[0011] The cooking appliance 100 illustrated in FIGS. 1 and 2 is to cook an object to be
heated. The object to be heated is exemplified by a food material. The cooking appliance
100 includes a heating chamber 1, the opening and closing member 2, an operation panel
3, and a cooking chamber 100A.
[0012] In the present embodiment, a side of the cooking appliance 100 where the operation
panel 3 is arranged is assumed as the front side of the cooking appliance 100, and
a side (back face side) opposite to the front side is defined as the rear side of
the cooking appliance 100. A right side of the cooking appliance 100 as viewed from
the front side is assumed as the right side of the cooking appliance 100, and a side
opposite to the right side is defined as the left side of the cooking appliance 100.
An upper side of the cooking appliance 100 as viewed from the front side is assumed
as the upper side of the cooking appliance 100, and a side (bottom side) opposite
to the upper side is defined as the lower side of the cooking appliance 100. The sides
as above do not limit the orientation of the cooking appliance 100 upon use.
[0013] As illustrated in FIGS. 1 and 2, the heating chamber 1 is a box-shaped member. Specifically,
the heating chamber 1 has a right outer wall 1G, a left outer wall 1H, a top outer
wall 1J, a bottom outer wall 1F, and a rear outer wall 1K. The heating chamber 1 houses
the cooking chamber 100A.
[0014] The opening and closing member 2 opens and closes the cooking chamber 100A. The opening
and closing member 2 is rotatable about one side of the left outer wall 1H as an axis
of rotation, for instance. To be specific, the opening and closing member 2 is openably
supported by a hinge (hinging member).
[0015] The operation panel 3 accepts an operation by a user. Examples of the operation include
a process for cooking the object to be heated. Specifically, the operation panel 3
includes a display, a storage, and a controller. The display displays various kinds
of information. A specific display includes a liquid crystal panel.
[0016] Next referring to FIG. 3, the cooking appliance 100 is detailed. FIG. 3 is an exploded
perspective view of the cooking appliance 100 according to the present embodiment.
Specifically, FIG. 3 illustrates the cooking appliance 100, from which the heating
chamber 1 has been removed.
[0017] The cooking chamber 100A illustrated in FIG. 3 is to take in the object to be heated.
The shape of the cooking chamber 100A is nearly rectangular-parallelepipedic, for
instance. Specifically, the cooking chamber 100A has a right wall 1A, a left wall
1B, a rear wall 1E, an opening 100B, a top wall 1C, and a bottom wall 1D. The opening
100B opens in a first direction D1. The first direction D1 is a forward direction.
The opening 100B communicates with the exterior of the cooking chamber 100A. The rear
wall 1E is arranged apart from the opening 100B in a direction opposite to the first
direction D1. In other words, the opening 100B is opposite to the rear wall 1E.
[0018] The right wall 1A and the left wall 1B each extend from the rear wall 1E along the
first direction D1. The right wall 1A and the left wall 1B are opposite to each other
in a second direction D2. The second direction D2 is a leftward direction.
[0019] The top wall 1C and the bottom wall 1D each extend from the rear wall 1E along the
first direction D1. The top wall 1C and the bottom wall 1D are opposite to each other
in a third direction D3. The third direction D3 is an upward direction (direction
opposite to the vertical direction).
[0020] The right wall 1A, the left wall 1B, the top wall 1C, the bottom wall 1D, and the
rear wall 1E are made of metal, for instance.
[0021] A space R is formed between the heating chamber 1 and the cooking chamber 100A. Specifically,
the space R is located between the right outer wall 1G of the heating chamber 1 and
the right wall 1A. The space R is also located between the top outer wall 1J of the
heating chamber 1 and the top wall 1C.
[0022] The cooking appliance 100 further includes a grill 16. The grill 16 is arranged in
the space R between the top wall 1C and the top outer wall 1J. The grill 16 conducts
heat generated by a heater to the object to be heated, so as to cook the object to
be heated.
[0023] The cooking appliance 100 further includes an illuminator 300, a holder 400, and
a fitting acceptor 500. The illuminator 300 illuminates the cooking chamber 100A.
To the fitting acceptor 500, the holder 400 is fitted. The holder 400 holds the illuminator
300. The illuminator 300, the holder 400, and the fitting acceptor 500 are arranged
in the space R. The illuminator 300, the holder 400, and the fitting acceptor 500
are arranged on an upper side of the right wall 1A. The illuminator 300, the holder
400, and the fitting acceptor 500 are arranged on a front side of the right wall 1A.
[0024] In the top wall 1C, a plurality of openings are provided in a region located below
the illuminator 300. As a result, the illuminator 300 illuminates the cooking chamber
100A. The illuminator 300 emits light toward the rear wall 1E and the bottom wall
1D of the cooking chamber 100A. As a result, the interior of the cooking chamber 100A
or the object to be heated as placed in the interior of the cooking chamber 100A is
irradiated with the light. Such irradiation makes it possible to observe at length
the interior of the cooking chamber 100A or the object to be heated as placed in the
interior of the cooking chamber 100A.
[0025] Next referring to FIGS. 4 and 5, the illuminator 300, the holder 400, and the fitting
acceptor 500 are detailed. FIG. 4 is an enlarged perspective view illustrating the
illuminator 300, the holder 400, and the fitting acceptor 500 in the present embodiment.
FIG. 5 is an enlarged perspective view illustrating the illuminator 300, the holder
400, and the fitting acceptor 500 in the present embodiment.
[0026] As illustrated in FIG. 4, a lower end portion of the fitting acceptor 500 is secured
to an upper portion of the right wall 1A. The fitting acceptor 500 may be secured
to any of the right wall 1A, the left wall 1B, the top wall 1C, the bottom wall 1D,
the rear wall 1E, the right outer wall 1G, the left outer wall 1H, the top outer wall
1J, the bottom outer wall 1F, and the rear outer wall 1K.
[0027] Next referring to FIG. 6, the fitting acceptor 500 is detailed. FIG. 6 is an enlarged
perspective view illustrating the fitting acceptor 500 in the present embodiment.
As illustrated in FIG. 6, the fitting acceptor 500 includes a main body 510 and an
elastic body 520. The fitting acceptor 500 is made of a synthetic resin, for instance.
[0028] The main body 510 includes a perpendicular part 512 and a horizontal part 511. The
horizontal part 511 is nearly plate-shaped. The perpendicular part 512 and the horizontal
part 511 extend along a front and rear direction of the cooking appliance 100. To
be specific, the horizontal part 511 substantially has the shape of a plate perpendicular
to the third direction D3. The horizontal part 511 is secured on the upper side of
the right wall 1A. The perpendicular part 512 is nearly plate-shaped. To be specific,
the perpendicular part 512 substantially has the shape of a plate perpendicular to
the second direction D2. A lower portion of the perpendicular part 512 is secured
to an upper face of the horizontal part 511.
[0029] The elastic body 520 has the shape of a stick extending along an up and down direction.
The elastic body 520 extends along the third direction D3. A lower portion of the
elastic body 520 communicates with the upper face of the horizontal part 511. The
perpendicular part 512 and the elastic body 520 are spaced apart. Specifically, the
elastic body 520 is arranged apart from the perpendicular part 512 in the second direction
D2. In addition, the elastic body 520 is arranged apart from the perpendicular part
512 in the first direction D1. In other words, the elastic body 520 is arranged on
a side of the fitting acceptor 500 closer to the opening and closing member 2.
[0030] The elastic body 520 is elastically deformable with respect to the main body 510.
For instance, an upper portion of the elastic body 520 is elastically deformable along
the second direction D2. In other words, the upper portion of the elastic body 520
is elastically deformable along a direction perpendicular to the right wall 1A. In
other words again, the upper portion of the elastic body 520 is elastically deformable
in a direction where the illuminator 300 protrudes from the holder 400.
[0031] Next referring to FIG. 7, the illuminator 300 and the holder 400 are detailed. FIG.
7 is an enlarged perspective view illustrating the illuminator 300 and the holder
400 in the present embodiment. As illustrated in FIG. 7, the holder 400 includes a
first interlocker 410 and a second interlocker 420.
[0032] The first interlocker 410 is nearly plate-shaped. To be specific, the first interlocker
410 substantially has the shape of a plate perpendicular to the second direction D2.
The first interlocker 410 is interlocked with the main body 510. Specifically, the
first interlocker 410 is secured to the main body 510.
[0033] The second interlocker 420 is nearly plate-shaped. To be specific, the second interlocker
420 substantially has the shape of a plate perpendicular to the second direction D2.
The second interlocker 420 is interlocked with the elastic body 520. Specifically,
the second interlocker 420 is secured to the elastic body 520. The elastic body 520
is elastically deformable with respect to the main body 510. If the elastic body 520
moves along the second direction D2, for instance, the second interlocker 420 also
moves along the second direction D2.
[0034] When the opening and closing member 2 is opened or closed, the right wall 1A sometimes
vibrates along the second direction D2. Such vibration of the right wall 1A is transmitted
to the illuminator 300. If the right wall 1A vibrates along the second direction D2,
for instance, the elastic body 520 relieves the vibration of the right wall 1A. To
be specific: If the right wall 1A instantaneously moves along the second direction
D2, the elastic body 520 slowly transmits the movement of the right wall 1A to the
illuminator 300.
[0035] As described above with reference to FIGS. 1 through 7, the elastic body 520 of the
fitting acceptor 500 is elastically deformable with respect to the main body 510 of
the fitting acceptor 500. Consequently, the elastic body 520 is able to absorb the
impact of opening and closing of the opening and closing member 2. As a result, the
transmission of the impact of opening and closing of the opening and closing member
2 to the illuminator 300 is suppressed.
[0036] Since the elastic body 520 has the shape of a stick extending along the up and down
direction, the transmission of the impact of opening and closing of the opening and
closing member 2 to the illuminator 300 is suppressed with a simple configuration.
[0037] Next referring to FIGS. 8 through 10, the illuminator 300 and the holder 400 are
detailed. FIGS. 8 and 9 are perspective views illustrating the illuminator 300 in
the present embodiment. FIG. 10 is a perspective view illustrating the holder 400
in the present embodiment. As illustrated in FIGS. 8 through 10, the illuminator 300
and the holder 400 are separable from each other.
[0038] The illuminator 300 includes a bulb 310 and a socket 320, for instance. The bulb
310 has a filament. The bulb 310 is nearly cylindrical in shape with a center axis
extending along the second direction D2. The illuminator 300 may be a light emitting
diode (LED).
[0039] The socket 320 is nearly tubular in shape with a center axis extending along the
second direction D2. The socket 320 is made of a synthetic resin, for instance. To
the socket 320, the bulb 310 is attached. The bulb 310 is attached to the socket 320
through a screw-in mechanism, for instance. Specifically, the bulb 310 is attached
to the left of the socket 320 in the second direction D2.
[0040] The socket 320 has a tubular body 322, a first protrusion 323, a second protrusion
324, and a projected part 321. The first protrusion 323 protrudes outward from the
tubular body 322. Specifically, the first protrusion 323 extends from the tubular
body 322 along the direction opposite to the first direction D1. The first protrusion
323 has a first slit 323a extending along the up and down direction. The first slit
323a is recessed in the first direction D1.
[0041] The second protrusion 324 protrudes outward from the tubular body 322. Specifically,
the second protrusion 324 extends from the tubular body 322 along the first direction
D1. The second protrusion 324 has a second slit 324a extending along the up and down
direction. The second slit 324a is recessed in the direction opposite to the first
direction D1. The projected part 321 is nearly rectangular-parallelepipedic in shape.
The projected part 321 extends from the tubular body 322 along the third direction
D3.
[0042] The holder 400 includes a main body 470, a first socket anchor 430, a second socket
anchor 440, a recessed part 450, and a horizontal part 460. The recessed part 450
is an example of a "third interlocker". The main body 470 is nearly plate-shaped.
To be specific, the main body 470 substantially has the shape of a plate perpendicular
to the second direction D2. The holder 400 is made of metal or a synthetic resin,
for instance.
[0043] The recessed part 450 is interlocked with the projected part 321. The recessed part
450 is arranged between the first interlocker 410 and the second interlocker 420.
[0044] The first socket anchor 430 is arranged between the first interlocker 410 and the
recessed part 450. The first socket anchor 430 protrudes from the main body 470 in
the second direction D2. The first socket anchor 430 is inserted into the first slit
323a. Specifically, the first socket anchor 430 abuts a left face of the first slit
323a in the second direction D2, and the main body 470 abuts a right face of the first
slit 323a in a direction opposite to the second direction D2.
[0045] The second socket anchor 440 is arranged between the recessed part 450 and the second
interlocker 420. The second socket anchor 440 protrudes from the main body 470 in
the second direction D2. The second socket anchor 440 is inserted into the second
slit 324a. Specifically, the second socket anchor 440 abuts a left face of the second
slit 324a in the second direction D2, and the main body 470 abuts a right face of
the second slit 324a in the direction opposite to the second direction D2.
[0046] The illuminator 300 is arranged between the recessed part 450 and the fitting acceptor
500 in the up and down direction.
[0047] The horizontal part 460 is nearly plate-shaped. To be specific, the horizontal part
460 substantially has the shape of a plate perpendicular to the third direction D3.
The horizontal part 460 is arranged in an upper portion of the holder 400. As a result,
it is possible to press the horizontal part 460 when the first interlocker 410 is
inserted into an insertion acceptor 513 and the second interlocker 420 is interlocked
with the elastic body 520, so that the rotation of the holder 400 is facilitated.
[0048] As described above, the socket 320 and the holder 400 are different members. Consequently,
the socket 320 and the holder 400 can each be made of a more preferable material.
For instance, the socket 320 is made of a synthetic resin and the holder 400 is made
of metal or a synthetic resin.
[0049] The holder 400 includes the first socket anchor 430, the second socket anchor 440,
and the recessed part 450 and is as such able to suppress the rotation as well as
frontward and rearward tilts of the socket 320. Specifically, the interlock of the
projected part 321 and the recessed part 450 with each other suppresses the rotation
of the socket 320, and the interlock of the first slit 323a and the first socket anchor
430 with each other and the interlock of the second slit 324a and the second socket
anchor 440 with each other suppress the rotation as well as frontward and rearward
tilts of the socket 320. As a result, the vibration transmitted to the illuminator
300 is suppressed, so that the load on the illuminator 300 is reduced.
[0050] Moreover, the illuminator 300 is arranged between the first interlocker 410 and the
second interlocker 420, so that the transmission of the impact of opening and closing
of the opening and closing member 2 to the illuminator 300 is further suppressed.
[0051] Referring to FIGS. 5 and 6 again, the fitting acceptor 500 is detailed. As illustrated
in FIGS. 5 and 6, the elastic body 520 includes a first regulator 521 and a second
regulator 522. The first regulator 521 and the second regulator 522 are arranged on
a side farther from the cooking chamber 100A of the elastic body 520. The first regulator
521 and the second regulator 522 are spaced apart in the up and down direction. The
second interlocker 420 is arranged between the first regulator 521 and the second
regulator 522.
[0052] The second regulator 522 preferably extends in a direction inclined to a direction
where the first regulator 521 extends. To be specific, the distance between the second
regulator 522 and the first regulator 521 is gradually reduced in the first direction
D1. As a result, the movement in the first direction D1 of the second interlocker
420 with respect to the elastic body 520 is regulated.
[0053] The first regulator 521 protrudes more in the direction opposite to the second direction
D2 as the first regulator 521 extends lower. Such configuration makes it easy to arrange
the second interlocker 420 between the first regulator 521 and the second regulator
522.
[0054] The main body 510 includes the insertion acceptor 513. The insertion acceptor 513
is arranged on a side of the main body 510 closer to the cooking chamber 100A. The
first interlocker 410 is inserted into the insertion acceptor 513 so as to interlock
the insertion acceptor 513 with the first interlocker 410. The insertion acceptor
513 is in the form of a pocket opened in the first direction D1. As a result, it is
possible to regulate the movement in the direction opposite to the first direction
D1 of the first interlocker 410 with respect to the main body 510. It is preferable
that the insertion acceptor 513 is nearly rectangular in shape with at least one corner
rounded. Such shape facilitates the rotation of the holder 400 when the first interlocker
410 is inserted into the insertion acceptor 513 and the second interlocker 420 is
interlocked with the elastic body 520.
[0055] The following description is made with reference to FIG. 11 so as to fully explain
an attachment method for attaching the illuminator 300 and the holder 400 to the fitting
acceptor 500. FIG. 11 is a perspective view for explaining the attachment method.
As illustrated in FIG. 11, a manufacturer initially inserts the first interlocker
410 into the insertion acceptor 513.
[0056] Next, the manufacturer rotates the illuminator 300 and the holder 400 about the insertion
acceptor 513 as an axis of rotation. The second interlocker 420 then causes the upper
portion of the elastic body 520 to move in the second direction D2. The manufacturer
further rotates the illuminator 300 and the holder 400 about the insertion acceptor
513 as the axis of rotation. The upper portion of the elastic body 520 moves in a
direction opposite to the second direction D2 and, as a result, the second interlocker
420 is arranged between the first regulator 521 and the second regulator 522. As described
before, the elastic body 520 is arranged on the side closer to the opening and closing
member 2 of the fitting acceptor 500, which facilitates attachment works.
[0057] The embodiment of the present invention has been described above with reference to
the drawings. The present invention, however, is not limited to the above embodiment
but worked in various modes without departing from the gist thereof. In the figures,
respective components are chiefly illustrated in a schematic manner for easier understanding,
and the illustrated components are different in thickness, length, number, and the
like from actual components as a matter of convenience of drawing the figures. The
material, shape, size, and the like of each component described in the above embodiment
are merely examples and are not particularly limited, and various modifications can
be made as long as the effects of the present invention are practically achieved.
- (1) In the embodiment described with reference to FIGS. 1 through 11, the opening
and closing member 2 is rotatable about one side of the left outer wall 1H as the
axis of rotation, to which the present invention is not limited. The opening and closing
member 2 may be drawable in the first direction D1.
- (2) In the embodiment described with reference to FIGS. 1 through 11, the elastic
body 520 has the shape of a stick extending along the up and down direction, to which
the present invention is not limited. The elastic body 520 may be a spring.
- (3) In the embodiment described with reference to FIGS. 1 through 11, the illuminator
300 and the holder 400 are separable from each other, to which the present invention
is not limited. The illuminator 300 and the holder 400 may be integrated with each
other.
