A WHITE GOOD

Description

Technical Field

[0001] Present invention relates to white goods, such as ovens, in which a certain temperature value should be maintained during operation, and to operation methods of these white goods.

Prior Art

[0002] During operation of some white goods such as ovens, a certain temperature value should be maintained in a compartment comprised therein. Especially for the white goods in which high temperature values are obtained in the compartment, this high temperature value may damage components provided in the control panel where operation of the white good is arranged. In order to prevent this situation, in the white goods, a fan is utilised which provides to circulate outer environment air, having lower temperature than the temperature within the compartment, in a channel to cool said components. However, high temperature value within the compartment does not merely affect said components. Especially during a process like cooking performed within the compartment or at the end of the process, when a door controlling the access to the compartment is opened, air having the high temperature within the compartment and containing gases which are released after foods burn during the cooking process reaches to the outer environment through the opened door, and in the meantime, it negatively affects the user opening the door and/or furniture being close to the white good. For example, the user may suffer from burn problem and deteriorations may occur in the furniture due to this high temperature.

[0003] In order to solve said problem, the patent document no. US3387600A discloses an air curtain means obtained by blowing air through the side walls of an oven. The oven disclosed in said document comprises a fan provided at a bottom side of the cooking compartment; holes provided at a side edge of the compartment; a flexible hose which allows the outer environment air drawn by the fan to reach to the holes; and a sensor which senses that the door is opened. In the invention disclosed in said document, the sensor senses when the door is opened, and the fan is enabled to operate. When the fan operates, the outer environment air is transmitted to the holes through the hose, and is reached to door opening through the holes so as to form an air curtain in front of the compartment. By this way, the user is prevented from being negatively affected by the high temperature within the compartment. However, practice disclosed in said document requires making a lot of modification in existing ovens to obtain the air curtain, thereby both complicating the manufacturing process and increasing the manufacturing costs. In addition to this, in said document, there is no practice to prevent the high temperature within the compartment, during the cooking process, from damaging the components which control operation of the oven.

[0004] In order to solve said problem, the patent document no. US2017082296A1 discloses an oven comprising a case, a cooking chamber, a door, a control unit, a convection fan, a cooling fan, a heat blocking unit and a door open/close detector. The cooking chamber is a cooking space formed by a top plate, a bottom plate, both side plates, and a rear plate. A control panel configured to control an operation of the oven is installed in an upper end portion of the case. The oven also include the cooling fan configured to cool the door. The cooling fan may allow the external air to flow in the inside of the case through the plurality of inhalation holes of the case and allow the air to be discharged to the front of the oven again. As the air is circulated through the cooling fan, the door and the whole inside of the case may be cooled. In the oven, a cooling channel may be installed in an upper side of the top plate to discharge the air inhaled through the cooling fan toward the front of the oven. The cooling channel may include an air discharge hole in one end thereof close to the door so as to discharge the inhaled air. The air discharge hole may be located in rear of the door so that the air passing through the cooling channel is discharged to the upper portion of the door. Accordingly, the speed of the air discharged from the narrowed air discharge hole may be increased. As the speed of the air is increased, the pressure of the air may be reduced, and a venturi effect that inhales the air of atmospheric pressure may be generated in a place which the air passes through. Accordingly, the pressure in the upper portion of the door which the discharged air passes through may be reduced, and thus the surrounding air may be collected to the upper portion of the door. The door may be cooled using the force that the surrounding air is collected to the upper portion of the door. In the oven, the control unit may be located over the door. The heat blocking unit may block high-temperature heat and water vapor discharged upwardly from the cooking chamber in response to the door being opened after the cooking so that the high temperature heat and water vapor are not directed to the user. The heat blocking unit may include a blocking plate, a hinge pin, and an elastic member. Thanks to the blocking plate a wind shield from the upper portion of the opening of the cooking chamber to a lower portion of the opening through collision of air continuously discharged toward the blocking plate with the blocking plate is formed. Therefore efficiently blocking high-temperature heat or water vapor emitted toward a front of the cooking chamber from the cooking chamber is ensured. However in said document, there is no practice to prevent the high temperature within the compartment, during the cooking process, from damaging the components which control operation of the oven.

Description of Invention

[0012] For the white goods such as ovens, a compartment comprised within the white good should have a high temperature during operation. However, this high temperature negatively affects the components located in the control panel where operation of the white good is arranged, and therefore the white good may be prevented to operate at a required efficacy. To this end, for such white goods within the known art, as shown in figure 1, a fan (M) is provided, and the fan (M) makes the outer environment air, having a temperature lower than the compartment (B), pass through a channel (H) which is in thermal interaction with the control panel (P) such that the components are prevented from being affected by the high temperature. The air, which is passed through the channel (K) and heated due to high temperature within the compartment (B), is transmitted to the outer environment through a cavity located between the door (D) and the control panel (P). However, this high temperature together with various gases formed in the compartment due to the high temperature, especially when the door of the white good is opened, may negatively affect the user and/or the furniture being close to the white good as well as said components. Within this context, with the present invention, there is developed a white good which prevents both the components in the control panel, the door, and the objects around the white good when the door is opened, from being negatively affected by the high temperature within the compartment and, an operation method for this white good.

[0013] The white good (A) developed with the present invention, exemplary views of which are illustrated in figures 2-3, comprises at least one body (G); at least one compartment (B) which is located in the body (G), which has a temperature higher than the outer environment temperature during the operation of the white good (A), which is surrounded by at least one first side (B1) (preferably top side or ceiling), at least one second side (B2) opposite to the first side (B1) (preferably bottom side or base), and at least one third side located between the first side (B1) and the second side (B2) such that it connects a part of the first side (B1) with a part of the second side (B2) being opposed to said part of the first side (B1), and which comprises at least one opening (B4) for access to inside that is preferably provided opposite to the third side (B3); at least one control panel (P) which is provided at the body (G), at a part of the first side (B1) which does not face the compartment (B) (preferably at a top part of the first side), and which arranges the operation of the white good (A); at least one door (D) which controls the access to the opening (B4), which has a closed position to prevent access to the opening (B4) and an opened position to allow access to the opening (B4), which is able to move for transition between these opened/closed positions (this movement may be both performed by rotating around an axis parallel to the second side (B2) as exemplified in the figures, and performed by sliding), which comprises at least one fourth side (D1) which approaches to and move away from the first side (B1) during this movement, wherein at least one cavity, being in connection with the outer environment, is formed between the control panel (P) (and preferably the first side B1)) and the door (A) when in the closed position; at least one channel (H), at least one part of which opens into the cavity, which has at least one inlet opening at at least another part, which is provided at the body (G) so as to be in thermal connection with the control panel (P) (between the first side (B1) and the control panel (P)), and which, preferably, has a cross-sectional area that narrows from the inlet opening towards the cavity; at least one fan (M) which is provided at the body (G) preferably so as to be at the part where the inlet opening is provided, which draws, through at least one hole provided on the body (G), the outer environment air having a temperature lower than the temperature within the compartment (B), which directs this drawn air into the channel (H) through the inlet opening, and which enables the air to pass through the channel (H) so as to reach to the cavity, which, by this way, cools the control panel (P) in order not to damage the components at the control panel (P) by the temperature within the compartment (B), and which operates at at least one first operating speed (e.g. within the range of 800-1200 revolutions per minute) when the door (D) is in the closed position. The developed white good (A) also comprising at least one flap arrangement (K), exemplary embodiments of which are illustrated in figure 4 and figure 8 to figure 12, which comprises: at least one first hinge (K2) (preferably at least two); at least one first flap (K1) which has a plate structure extending parallel to the first side (B1), which is in connection with the first hinge (K2) so as to be able to move by rotating around an axis via at least one torsion spring preferably located at the first hinge (K2), which has a first position that allows the air, reaching to the cavity through the channel (H), to pass to the outer environment when the door (D) is in closed position, and a second position that enables the air reaching to the cavity to be directed, preferably in parallel with the opening (B4) or vertically to the second side (B2), towards the opening (B4) (and therefore towards the second side (B2)) by posing an obstacle to the connection of the cavity with the outer environment when (D) the door is opened (in the second position, there is no angle other than 0° exists between the first hinge (K2) and the first flap (K1)); and at least one movement equipment which allows the first flap (K1) to be in the first position when the door (D) is in the closed position, and allows the first flap (K1) to take place in the second position when the door (D) is opened.

[0014] In an exemplary embodiment of the invention, when the white good (A) is operated, the temperature within the compartment (B) reaches to a higher temperature than the outer environment within which the white good (A) is present. For that reason, in order not to affect the control panel (P) which arranges the operation of the white good (A) by the high temperature at the compartment (B), when the white good (A) starts to operate, the fan (M) also starts to operate. When the fan (M) operates, the outer environment air is drawn through the hole provided at the body (G) such that it is directed to the channel (H) through the inlet opening. Due to the fact that the channel (H) is in thermal connection with the control panel (P), the outer environment air circulating in the channel (H) both prevents control panel (P) from being affected by the temperature in the compartment (B), and cools the control panel (P). In the meantime, because of the fact that the door (D) is closed, the first flap (K1) is in the first position, and therefore the cavity is in connection with the outer environment. By this way, the air circulating through the channel (H) reaches to the cavity to pass to the outer environment. As shown in figure 3, when the door is started to be opened, the first flap (K1) rotates around the axis, passing through the region where it is in connection with the first hinge (K2), by moving such that its free side which is not in connection with the first hinge (K2) moves away from the first hinge (K2), and takes place in the second position in which the first flap (K1) is inclined with respect to the first side (B1), by this way, pose an obstacle to the connection of the cavity with the outer environment, and enables the air, which reaches from the channel (H) to the cavity, to be directed to the opening (B4) and therefore to the second side (B2) other than the outer environment. By this way, an air curtain is formed between the opening (B4) and the door (D), and the air inside the compartment (B) is prevented from escaping directly to the outer environment such that the user, objects like furniture that are present around the white good (A) are able to be prevented from being negatively affected by the hot air and gases inside the compartment (B). In addition to this, thanks to using equipment that are already provided in the white good (A) and adding only the flap arrangement (K) to the white good (A), a white good (A) is obtained which is cheap, easy and practical to produce.

[0015] In a preferred embodiment of the invention, the fan (M) has at least one second operating speed (e.g. within the range of 1200-1500 revolutions per minute) higher than the first operating speed, and the developed white good (A) preferably comprises at least one first sensor (K3) which, by sensing movement of the first flap (K1), enables to operate the fan (M) at the first operating speed if the first flap (K1) is in the first position and to operate the fan (M) at the second operating speed if the first flap (K1) is in the second position, and which accordingly controls the operating speed of the fan (M). By this way, it is able to be provided to form a more efficient air curtain in front of the opening (B4). The first sensor (K3) may preferably be a mechanical switch, an ultrasonic sensor, a laser sensor, an inductive sensor, a light sensor or a capacitive sensor. Operating time change of the fan (M) can be performed mechanically by the first sensor (K3), or by a control unit comprised within the white good (A) such that the control unit processes the signals received from the first sensor (K3).

[0016] In an embodiment of the invention which is shown in figure 4, the movement equipment preferably comprises at least one first protrusion (K4) provided at the surface of the first flap (K1) that faces the opening (B4) when in the first position, and at least one second protrusion (D2) provided at the fourth side (D1) of the door (D) so as to be in contact with the first protrusion (K4) when the first flap (K1) is in the first position. In this embodiment, while the door (D) takes place in the closed position from the opened position, the second protrusion (D2) contacts with the first flap (K4), thereby allowing the first flap (K1), being in the second position, to take place in the first position. When the door (D) takes place in the closed position, since the second protrusion (D2) and the first protrusion (K4) are in contact with each other, the first flap (K1) takes place in the first position so as to maintain this position until the door (D) starts to be opened. Therefore, when the door (D) is in the closed position, the first flap (K1) does not obstruct the connection of the cavity with the outer environment, and the air passing through the channel (H) is able to be delivered to the outer environment efficiently.

[0017] In another embodiment of the invention which is shown in figure 5, the movement equipment preferably comprises at least two movement elements (1a) (e.g. a coil, a pulley, a wheel etc.) which are provided such that at least one of them is at the part of the opening (B4) which is close to the first side (B1), and at least another of them is at the part of the opening (B4) which is close to the second side (B2); and at least one tension member (1b) (e.g. a rope, a wire etc.) which is connected, from at least one part, to the flap equipment (K) (to the first hinge (K2) or the first flap (K1)) by passing on the movement element (1a) which is provided at the part that is close to the first side (B1), and connected, from at least another part, to the door (D) (preferably to a part of the door (D) that is close to the second side (B2)) by passing on the movement element (1a) which is provided at the part that is close to the second side (B2), and which enables the first flap (K1) to take place in the second position when the door (D) takes place in the opened position, and enables the first flap (K1) to take place in the first position when the door (D) takes place in the closed position. Therefore, movement of the first flap (K1) is able to be practically controlled.

[0018] In another preferred embodiment which is shown in figure 6, the movement equipment comprises at least one first gear (2a) (e.g. a rack and pinion gear, a worm gear etc.) which is in connection with the door (D) and which is able to move with the movement of the door (D); at least one second gear (2b) (e.g. a pinion gear) which is in connection with the first gear (2a) and which transfer the movement of the first gear (2a) by moving (e.g. by rotating); at least one transfer element (2c) which is in connection with the second gear (2b) from at least one part, wherein the movement of the first gear (2a) (and therefore the door (D)) is transferred to the transfer element (2c) via the second gear (2b), which is able to rotate around its own axis as a result of this movement transfer, and which is preferably in the form of a shaft; and at least one third gear (2d) which is in connection with another part of the transfer element (2c) from one part, and in connection with the flap arrangement (K) from another part, which is able to move (e.g. rotate) with the rotational movement of the transfer element (2c), and which, as a result of this movement, enables the first flap (K1) to take place in the first or the second position. In this embodiment, when the door starts to open, it make the first gear (2a) move in a direction, and movement of the first gear (2a) and therefore of the door (D) is transferred to the transfer element (2c) via the second gear (2b). As a result of this movement transfer, the transfer element (2c) starts to rotate around its own axis in a direction (in clockwise or anti-clockwise), and with this rotational movement, it makes the third gear (2d) that is in connection with the transfer element move in a direction. Since the third gear (2d) is in connection with both the transfer element (2c) and the flap arrangement (K), the third gear (2d) allows the first flap (K1) to take place in the second position by moving with the movement received from the transfer element (2c). While the door (D) takes place in the closed position from the opened position, the first gear (2a) moves in a direction opposite to the movement direction occurring when the door (D) is opening, and this movement being in the opposite direction is transferred to the transfer element (2c) via the second gear (2b) such that the transfer element (2c) is enabled to rotate in a direction opposite to the rotation direction occurring when the door (D) is opening. This rotation of the transfer element (2c) which is in the opposite direction enables to move the third gear (2d) in a direction opposite to its initial movement direction, thus the first flap (K1) takes place in its first position when the door (D) is closed. Thanks to this embodiment, for the different opened positions of the door (D) (e.g. for different angles between the opening (B4) and the door (D)), various angles are provided between the first flap (K1) and the first hinge (K2) such that the first flap (K1) have different positions in the second position (e.g. the first flap (K1), in any position of the door (D) at each angle, can be allowed to be positioned so as to extend parallel to the fourth side (D1)). This case also provides to adjust the opening amount of the first flap (K1) according to the opening amount of the door (D) (in other words, obstructing the connection of the cavity with the outer environment)), thereby obtaining an efficient white good (A). In this embodiment, the developed white good (A) also preferably comprises at least one fourth gear (2e) which provides the connection of the third gear (2d) with the flap arrangement (K) (and therefore with the first flap (K1)) in order to be able to transfer the movement of the door (D) to the first flap (K1) in a more efficient manner, and at least one fifth gear (2f) which is located between the second gear (2b) and the transfer element (2c), and which transfers the movement of the second gear (2b) to the transfer element (2c). In another alternative embodiment, the white good (A) preferably comprises at least one sixth gear (2g) which is provided between the third gear (2d) and the fourth gear (2e), and which transfers the movement of the third gear (2d) to the fourth gear (2e).

[0019] In another exemplary embodiment shown in figure 7, the developed white good (A) preferably comprises at least one second sensor (3a) which senses the opened/closed positions of the door (D), and at least one motor (3b) which is in connection with the flap arrangement (K), and which enables the first flap (K1) to take place in the first position or the second position according to the opened/closed positions of the door (D) determined by the second sensor (3a). In this embodiment, the second sensor (3a) produces different signals according to the closed position, opened position of the door (D) and to the opening amount between the door (D) and the opening (B4), and the produced signals are transmitted to the control unit of the white good (A). In accordance with these signals, the control unit determines the angle amount that should be between the first hinge (K2) and the first flap (K1), and therefore determines the position that the first flap (K1) should have at the second position (e.g. the first flap (K1) is provided to be parallel to the fourth side (D1) continuously) and accordingly, adjusts the position of the first flap (K1) by energising the motor (3b). By this way, an efficient air curtain is provided to be formed at the opening (B4) so as to obtain a reliable white good (A).

[0020] In a preferred embodiment of the invention, the first hinge (K2) is in connection with the body (G) (preferably so as to be in a bottom region of the control panel (P)) from a part which is not in connection with the first flap (K1). In another preferred embodiment, the white good (A), as shown in figure 8 and figure 9, comprises at least one second hinge (K5), wherein another part of the first hinge (K2) that is not in connection with the first flap (K1) is connected to at least one part of the second hinge (K5), and wherein the second hinge (K5), from at least another part, is connected to the body (G) via at least one joint (K6) so as to be able to achieve rotary movement in the joint (K6) axis. Thanks to the second hinge (K5), when the first flap (K1) takes place in the first position, it rotates in the joint (K6) axis, and it takes place an inclined position such that an acute angle is formed between the first flap (K1) and the second hinge (K5) (e.g. such that the part which is in connection with the first hinge (K2) is at a higher location than the part which is in connection with the body (G)). By this way, when the door (D) is in the closed position, the first flap (K1) is provided to be positioned such that the connection of the cavity with the outer environment is not obstructed even a little, thereby obtaining an efficient white good (A).

[0021] In another alternative embodiment of the invention which is provided in figure 10, preferably, at least one end part of the first flap (K1) (preferably both of the end parts) has a folded structure such that it forms a lug towards the part of the first flap (K1) facing the first hinge (K2) when in the first position. By this way, when the first flap (K1) is in the second position, the air reaching to the cavity through the channel (H) is prevented from escaping to the outer environment from these end parts such that all of the air is utilised in formation of the air curtain, thereby increasing the efficacy of the air curtain.

[0022] In an example which is not part of the claimed invention, the white good (A), as shown in figure 11, preferably comprises at least one second flap (K7) which is in connection with the first flap (K1) so as to move on the first flap (K1) by sliding (preferably at the part of the first flap (K1) facing the first hinge (K2) when in the first position); and by this way, which, when the first flap (K1) is in the second position, is provided collaterally (or one on the top of the other) with the first flap (K1) such that it moves away from the first flap (K1) from the side of the first flap (K1) being opposite to the side that is in connection with the first hinge (K2) (in other words, such that it extends towards the door (D) or the opening or the second side (B1)); and which, when the first flap (K1) is in the first position, is provided on the first flap (K1) (preferably between the first flap (K1) and the first hinge (K2)) such that it matches up with the first flap (K1). By this way, the air reaching to the cavity is provided to form an air curtain in a more efficient manner.

[0023] As shown in figure 12, the white good (A) comprises at least one second flap (K7) which is connected to a side of the first flap (K1) being opposite to the side that is in connection with the first hinge (K2) such that it is able to move by rotating around a rotation axis (K8) parallel to said opposite side; which, when the first flap (K1) is in the second position, is provided collaterally (or one on the top of the other) with the first flap (K1) such that it moves away from the first flap (K1) from the opposite side (in other words, such that it extends towards the door (D) or the opening or the second side (B1)); and which, when the first flap (K1) is in the first position, is provided on the first flap (K1) (preferably between the first flap (K1) and the first hinge (K2)) such that it matches up with the first flap (K1) by rotating around the rotation axis (K8). I According to the invention, while the first flap (K1) takes place in the second position from the first position, the second flap (K7) positions alongside the first flap (K1) by rotating around the rotation axis (K8) such that the side being in connection with the first flap (K1) is collateral to said opposite side of the first flap (K1). Also, while the first flap (K1) returns to the first position, it laps on the first flap (K1) by rotating around the rotation axis (K8). Thanks to these features, connection of the cavity with the outer environment is obstructed in a more efficient manner, and the air amount transmitted to the opening (B4) is increased such that the air curtain becomes more efficient.

[0024] In another embodiment of the invention, the developed white good (A) preferably comprises at least one suction hole (preferably more than one) provided at the part (preferably at the side) of the door (D) that is close to the second side (B2), and at least one air circulation channel which is provided within the door (D), a part of which opens into the suction hole, and another partof which opens into the cavity. In this embodiment, when the door (D) is in the closed position, with the negative pressure forming due to heated air which reaches to the cavity through the channel (H) and which is sent to the outer environment through the cavity; the outer environment air is sucked through the suction hole such that it is received to the air circulation channel, and the air passing through the air circulation channel is sent to the outer environment through the cavity. By this way, the door (D) is prevented from being affected by the high temperature of the compartment (B).

[0025] In the operation method of the white good (A) developed by the present invention, the fan (M), which has the first operating speed and the second operating speed and which operates at the first operating speed when the door (D) is in the closed position, is provided to operate immediately at the second operating speed via the first sensor (K3) when the door (D) opens. In another preferred embodiment, the fan (M) operating at the first operating speed is provided to operate at the second operating speed via the first sensor (K3) following a first time after the door (D) opens. Thanks to this embodiment, while the door (D) is opening, the air having a temperature lower than the temperature of the compartment (B) is provided to be received inside the compartment (B) in fewer amounts such that the air within the compartment (B) is provided to be hotter. In another preferred embodiment, after being operated at the second operating speed for a second time, the fan (M) is passed to the first operating speed again via the first sensor (K3). The second time is determined to be such a time that the air having a high temperature within the compartment (B) is lowered to a temperature which does not harm any object. By this way, the fan (M) is prevented from consuming energy unnecessarily, and the user is provided to be minimally affected by the loud noise forming due to operation of the fan (M) at high revolutions.

[0026] Thanks to the white good (A) and the operation method developed by the present invention, it is provided that the air directed to the outer environment by the fan (M), which enables to cool the components that are already provided at the white good (A) and located at the control panel (P), forms an air curtain between the opening (B4) and the door (D) by being directed to the compartment (B) opening (B4) when the door (D) is in the closed position; therefore objects around the white good (A) can be prevented to be negatively affected by the air and gases of high temperature which are released from the compartment (B) to the outer environment when the door (D) is opened, and thus, a white good (A) is obtained which is cheap, easy and practical to produce.
