Moreover, it is not required that the present disclosure is constructed or operated in a particular orientation, and shall not be construed to limit the present disclosure. In addition, the feature defined with "first" and "second" may indicate or imply that one or more of these features are provided. In the description of the present disclosure, the term "a plurality of' means two or more than two, unless specified otherwise.

[0023] In the description of the present disclosure, it should be understood that, unless specified or limited otherwise, the terms "mounted," "connected," and "coupled" are used broadly and may be such as fixed connections, detachable connections, or integral connections; may also be mechanical or electrical connections; may also be direct connections or indirect connections via intervening structures; may also be inner communications of two elements, which can be understood by those skilled in the art according to specific situations.

[0024] An outdoor unit for an air conditioner 100 according to embodiments of the present disclosure is described referring to FIG. 1 to FIG. 6. The outdoor unit for an air conditioner 100 can be a small multi-coupled-side-air-output outdoor unit. In the following description of the present disclosure, the small multi-coupled-side-air-output outdoor unit will be described as an example of the outdoor unit for an air conditioner 100. Certainly, one of ordinary skill in the art can understand that the outdoor unit for an air conditioner 100 can be other types of an outdoor unit for an air conditioner 100, and not limited to the small multi-coupled-side-air-output outdoor unit.

[0025] As illustrated in FIG. 1-FIG 6, the outdoor unit for an air conditioner 100 according to embodiments in a first aspect of the present application, such as the small multi-coupled-side-air-output outdoor unit, includes a body 1, a rotor 2, a welded member for electronic control 3, a waterproof member 5, and at least one baffle.

[0026] The rotor 2, the welded member for electronic control 3, the waterproof member 5, and the at least one baffle are all arranged in the body 1. Specifically, referring to FIG. 1 and FIG. 5, the welded member for electronic control 3 is arranged at a top portion within the body 1, and the welded member for electronic control 3 is located above the rotor 2. The welded member for electronic control 3 defines at least one opening in a bottom portion, and the electronic control component 4 is arranged in the welded member for electronic control 3. For example, in examples shown in FIG. 2 and FIG. 3, the welded member for electronic control 3 is in a shape of a substantial rectangle, and the welded member for electronic control 3 is open at a top portion and a right wall, such that the electronic control component 4 is mounted in the welded member for electronic control 3 from the upper to the lower. The opening runs through the bottom portion of the welded member for electronic control 3 in an up-down direction. The electronic control component 4 is provided with an electronic control element 41.

[0027] The waterproof member 5is connected to the bottom portion of the welded member for electronic control 3, and the waterproof member 5 is opposite to the opening. The waterproof member 5 and the welded member for electronic control 3 cooperatively define an airflow passage 51 in communication with the opening, two ends (a left end and a right end in FIG. 4, e.g.) of the waterproof member 5 are separately spaced apart from the welded member for electronic control 3 to define two airflow outlets 52 in communication with the airflow passage 51. As illustrated in FIG. 1 and FIG. 4, when the rotor 2 rotates (clockwise rotates, e.g.), air in the welded member for electronic control 3 can flow through the opening in the bottom portion of the welded member for electronic control 3, passes through the airflow passage 51 defined by the welded member for electronic control 3 and the waterproof member 5, and reaches at a side with the rotor 2 through the two airflow outlets 52 at two ends of the waterproof member 5, thereby carrying heat generated by the electronic control component 4 in the welded member for electronic control 3 during operation off. Therefore, with the two airflow outlets 52, heat generated by the electronic control component 4 during operation can quickly flow to the rotor 2 in quantity through the two airflow outlets 52, achieving quick ventilation and heat dissipation for the electronic control component 4.

[0028] Furthermore, with the arrangement that the waterproof member 5 is opposite the opening in the bottom portion of the welded member for electronic control 3, the waterproof member 5 shields the opening. For example, in case that the rotor 2 throws water, since the waterproof member 5 shields the opening in the bottom portion of the welded member for electronic control 3, water drops hardly comes into the welded member for electronic control 3 through the opening, guaranteeing normal operation of the electronic control component 4.

[0029] The baffle is arranged in the airflow passage 51 to prevent liquid from entering the welded member for electronic control 3 through the airflow passage 51. When the rotor 2 throws water, as illustrated in FIG. 5 and FIG. 6, with the baffle in the airflow passage 51, even water drops can enter the airflow passage 51 through the airflow outlets 52, the water drops hardly enter the welded member for electronic control 3 because of prevention by the baffle, thereby further guaranteeing the normal operation of the electronic control component 4.

[0030] In the outdoor unit for an air conditioner 100 according to embodiments of the present disclosure, such as the small multi-coupled-side-air-output outdoor unit, the waterproof member 5 is arranged at the bottom portion of the electrically controlled welded member 3 and opposite the opening, the waterproof member 5 and the welded member for electronic control 3 cooperatively define the airflow passage 51 in communication with the opening and the two airflow outlets 52 in communication with the airflow passage 51, and the baffle is arranged in the airflow passage 51, quick heat dissipation for the electronic control component 4 can be realized, and water and the like hardly enter the welded member for electronic control 3 through the opening, such that the electronic control component 4 in the welded member for electronic control 3 can normally operate.

[0031] According to some specific embodiments of the present disclosure, referring to FIG. 2, the waterproof member 5 is open at a top portion, two sides of the waterproof member 5 in a width direction are provided with connecting parts 53 respectively, and the connecting parts 53 extending outwards. The waterproof member 5 is connected to the bottom portion of the welded member for electronic control 3 by means of the connecting parts 53. Two ends (a left end and a right end in FIG. 2, e.g.) of the waterproof member 5 in a length direction are spaced apart from the welded member for electronic control 3 to define the two airflow outlets 52 respectively. For example, in the example in FIG. 2, each of the connecting parts 53 can extend outwards from a top edge of the waterproof member 5 in the width direction, the connecting parts 53 can be connected to the bottom portion of the welded member for electronic control 3 by means of screws, etc., such that the waterproof member 5 can be conveniently and firmly connected to the bottom portion of the welded member for electronic control 3 by means of the connecting parts 53. It should be noted herein, a direction "out" can be understood as a direction way from a center of the waterproof member 5, and an opposite direction is defined as "in", i.e. a direction towards the center of the waterproof member 5. Top surfaces of two ends of the waterproof member 5 in the length direction can be both lower than top surfaces of the two ends of the waterproof member 5 in the width direction, such that the two ends of the waterproof member 5 in the length direction can be spaced apart from the welded member for electronic control 3 to define the two airflow outlets 52 respectively. Therefore, the waterproof member 5 is simple in whole structure, easy to realize, and low in cost. Connection between the waterproof member and the welded member for electronic control 3 is convenient.

[0032] Optionally, as shown in FIG. 2-FIG 4, at least one of the two ends of the waterproof member 5 in the length direction is provided with an incline part 54, and the incline part 54 obliquely extends upwards in the direction away from the center of the waterproof member 5. The incline part 54 has a free end (a left end in FIG. 4, e.g.), and the free end is provided with a flange 55 horizontally extending outwards, an upper surface of the flange 55 is spaced apart from the bottom portion of the welded member for electronic control 3 to define the airflow outlet 52. For example, referring to FIG. 2 and FIG. 3 as well as FIG. 4, the incline part 54 obliquely extends upwards from a left end of the waterproof member 5, the flange 55 horizontally extends leftwards from a left end of the incline part 54. Therefore, with the incline part 54 and the flange 55, compared with a bottom wall of the waterproof member 5, the incline part 54 and the flange 55 are kept at smaller distances from the bottom portion of the welded member for electronic control 3. On the premise that air can smoothly pass through the airflow passage 51 and flow out through the airflow outlet 52, water and the like on the rotor 2 more hardly enter the waterproof member 5 through the airflow outlet 52, achieving a comparatively waterproof effect of the waterproof member 5.

[0033] Or optionally, as shown in FIG. 2-FIG. 4, at least one of the two ends of the waterproof member 5 in the length direction is provided with an extending part 56 vertically extending upwards. A top surface of the extending part 56 is spaced apart from the bottom portion of the welded member for electronic control 3 to define the airflow outlet 52. A distance between the top surface of the extending part 56 and the bottom portion of the welded member for electronic control 3 is less than a distance between the bottom wall of the waterproof member 5 and the bottom portion of the welded member for electronic control 3. Therefore, on the premise that air can smoothly pass through the airflow passage 51 and flow out through the airflow outlet 52, water and the like on the rotor 2 also more hardly enter the waterproof member 5 through the airflow outlet 52, also achieving a comparatively waterproof effect of the waterproof member 5. For example, referring to FIG. 2 and FIG. 3 as well as FIG. 4, the extending part 56 vertically extend upwards from a left end of the waterproof member 5, and the two ends of the extending part 56 in the length direction can extend to be in contact with two side walls of the waterproof member 5 in the width direction respectively, for a better waterproof effect.

[0034] It should be noted that, in examples in FIG. 2 to FIG. 4 and FIG. 6, one end of the waterproof member 5 in the length direction is provided with the incline part 54 and the flange 55, and the other end is provided with the extending part 56, in order to guarantee good ventilation and heat dissipation, as well as achieve the better waterproof effect. Certainly, the present disclosure is not limited thereto, each the two ends of the waterproof member 5 in the length direction can provided with the incline part 54 and the flange 55, or the extending part 56 (not shown in the drawings). It should be noted that, specific structures of the two ends of the waterproof member 5 in the length direction can be configured according to actually needs for better satisfying actual applications.

[0035] Optionally, referring to FIG. 6, a width of the airflow outlet 52 in an up-down direction is represented by a, a is greater than 0 mm and less than or equal to 10 mm. Therefore, when the width a of the airflow outlet 52 is greater than 10 mm, though heat of the electronic control component 4 can be carried out quickly, a risk that the water the like on the rotor 2 enter the waterproof member 5 through the airflow outlet 52 is large due to a large distance between ends of the waterproof member 5 in the length direction and the welded member for electronic control 3. In other words, by setting the width a of the airflow outlet 52 to fulfill 0<a≤10mm, on the premise of good ventilation and heat dissipation for the electronic control component 4, water and the like on the rotor 2 hardly enter the waterproof member 5 through the airflow outlet 52, thereby guaranteeing reliable operation of the electronic control component 4.

[0036] According to further embodiments of the present disclosure, as shown in FIG. 3, FIG. 4, and FIG. 6, the baffle includes a first sub-baffle 61, the first sub-baffle 61 surrounds the opening and extends downwards into the waterproof member 5. For example, referring to FIG. 3, FIG. 4, and FIG. 6, the opening is a substantial rectangular opening, the first sub-baffle 61 can be an annular baffle plate. The first sub-baffle 61 has an upper end connected to a side wall defining the opening, and a lower end vertically extending downwards and spaced apart from the bottom wall of the waterproof member 5. Therefore, with the above first sub-baffle 61, on the premise that the heat can be smoothly discharged, water drops entering the airflow passage 51 can be further stopped.

[0037] Furthermore, referring to FIG. 2, FIG. 4 and FIG. 6, the baffle further includes a second sub-baffle 62, the second sub-baffle 62 has a first end connected to the bottom portion of the electrically controlled welded member 3 and a second end extending downwards and spaced apart from the bottom wall of the waterproof member 5. The second sub-baffle 62 is arranged between the opening and the airflow outlet 52. For example, in examples of FIG. 2, FIG. 4, and FIG. 6, the second sub-baffle 62 is arranged between the first sub-baffle 61 and the airflow outlet 52 at a right side of the waterproof member 5. The second sub-baffle 62 is substantially L-shaped. Specifically, the second sub-baffle 62 includes a connecting plate horizontally extending and connected to the bottom portion of the welded member for electronic control 3, and a baffle part having a first end connected to the connecting plate and a second send vertically extending downwards. A lower end surface of the baffle part is spaced apart from a bottom wall of the waterproof member 5. Therefore, with the second sub-baffle 62, after water drops enter the airflow passage 51 through the airflow outlet 52 at the right side, firstly the second sub-baffle 62 stops the water drops. If some water droops can pass through the second sub-baffle 62, all the water drops can be substantially stopped at the first sub-baffle 61.

[0038] Furthermore, as shown in FIG. 3, FIG. 4, and FIG. 6, the opening includes a first orifice 31 and a second orifice 32 spaced apart from each other. The first sub-baffle 61 is connected at the first orifice 31. The second orifice 32 is located at a side of the first orifice 31 away from the second sub-baffle 62. A third sub-baffle 63 is arranged at the second orifice 32, and the third sub-baffle 63 is connected to a side wall of the second orifice 32 away from the first sub-baffle 61. For example, in examples in FIG. 3, FIG. 4, and FIG. 6, the third sub-baffle 63 is arranged between the airflow outlet 52 of the waterproof member 5 at the left side and the first sub-baffle 61, and the third sub-baffle 63 vertically extends downwards from a left side wall of the second orifice 32. Therefore, after water drops enter the airflow passage 51 through the airflow outlet 52 at the left side, firstly, the third sub-baffle 63 stops the water drops. If some water drops can pass through the third sub-baffle 63, all the water drops can also be substantially stopped at the first sub-baffle 61.

[0039] Therefore, with the above first sub-baffle 61, second sub-baffle, and third sub-baffle 63, a barrier of two layers can be achieved, water thrown from the rotor 2 hardly enters the welded member for electronic control 3 through the opening, thereby guaranteeing reliable operation of the electronic control component 4 in a long term.

[0040] Optionally, as shown in FIG. 6, the width of the airflow outlet 52 in the up-down direction is represented by a, a height of the first sub-baffle 61 is represented by b, a height of the second sub-baffle 62 is represented by c, and a distance between a bottom surface of the welded member for electronic control 3 and the bottom wall of the waterproof member 5 is represented by d, a, b, c, and d fulfill d≥a, a<b<d, and a<c<d. Therefore, by setting the width a of the airflow outlet 52 less than or equal to the distance d, water from outside hardly enters the waterproof member 5 through the airflow outlet 52. By setting the height b of the first sub-baffle 61 and the height c of the second sub-baffle 62 between the width a of the airflow outlet 52 and the distance d, on the premise that the stopping effect is guaranteed, heat generated during operation of the electronic control component 4 can be smoothly discharged. It should be noted that, Specific values of the above dimensions can be determined according to actual structure of the outdoor unit for an air conditioner 100.

[0041] According to some embodiments of the present disclosure, the electronic control component 4 is inverted in the welded member for electronic control 3. For example, in an example in FIG. 5, the electronic control element 41 is arranged at a lower surface of the electronic control component 4. During assembling, the electronic control component 4 is inverted and mounted to an upper portion of the body 1. Specifically, the electronic control component 4 can be mounted in the welded member for electronic control 3 from the upper to the lower.

[0042] The air conditioner according to embodiments of a second aspect of the present disclosure includes the outdoor unit for an air conditioner 100 according to embodiments of the first aspect of the present disclosure.

[0043] The whole performance of the air conditioner according to embodiments of the present disclosure can be improved with the outdoor unit for an air conditioner 100.

[0044] Other configurations and operations of the air conditioner according to embodiments of the present disclosure are known to those skilled in the art, which will not described in detail herein.
