In the drawings, the same or similar notations represent the same or similar parts or parts with the same or similar functions throughout.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0053] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood in a broad sense, for example, it can be fixed connection, or indirect connection through an intermediate medium, or internal communication of two elements or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0054] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0055] The terms "first", "second", "third" (if any) in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0056] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or display including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0057] In the prior art, the kitchen air conditioner includes a smoke machine unit, an air conditioner unit and an electric control box. The smoke machine unit is used to realize oil fume extraction, the air conditioner unit is used to realize temperature adjustment, and the electric control box is used to control the operation of the smoke machine unit and the air conditioner unit. However, the electric control box is easy to heat during operation, and the heat in the electric control box is not easy to dissipate in the kitchen air conditioner, which can cause damage to the electric control box.

[0058] After repeated thinking and verification, the inventor found that the kitchen air conditioner accommodates the air conditioner unit through two cavities, and the two cavities are used as cold cavities and heat cavities respectively. After the external gas of the kitchen air conditioner enters the cold cavity, the gas is cooled by the evaporator and then blown into the indoor through the air supply fan. The temperature in the cold cavity is relatively low. If the electric control box is installed in the cold cavity, the gas cooled by the evaporator can also flow through the electric control box, so that the electric control box can be cooled, and damage of the electric control box caused by high temperature can be avoided.

[0059] Therefore, the inventor designs a kitchen air conditioner. The shell of the kitchen air conditioner has a first cavity as a cold cavity. The evaporator, the air supply fan and the electric control box are installed in the first cavity respectively. The air supply fan can drive the external gas of the kitchen air conditioner to enter the first cavity and flow out of the first cavity from the air outlet of the shell. Along the flow direction of the gas in the first cavity, the electric control box is arranged downstream of the evaporator. In this way, the gas cooled by the evaporator can dissipate heat for the electric control box, so that damage of the electric control box caused by high temperature can be avoided.

[0060] The technical solutions of the kitchen air conditioner provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0061] Referring to FIG. 1, Figures 1 to 4 The kitchen air conditioner provided by the embodiments of the present application includes a shell 100, an air conditioner unit and an electric control box 500. The shell 100 has a first cavity 181. The shell 100 is provided with a first air inlet 1811 and a first air outlet 1812 which communicate with the first cavity 181. The first cavity 181 can be used as a cold cavity of the shell 100. The kitchen air conditioner can enter the first cavity 181 through the first air inlet 1811. The gas in the first cavity 181 can be blown to the indoor kitchen through the first air outlet 1812. For example, the first air inlet 1811 can be arranged at the top of the shell 100, and the first air outlet 1812 can be arranged at the front side of the shell 100, i.e. the side of the shell 100 facing the user.

[0062] The air conditioner unit includes an evaporator 210 and an air supply fan 220. The evaporator 210 and the air supply fan 220 are both installed in the first cavity 181. The air supply fan 220 is configured to drive the gas to flow into the first cavity 181 from the first air inlet 1811 and to flow out of the first cavity 181 from the first air outlet 1812.

[0063] The housing 100 also includes a second cavity 182 arranged side by side with the first cavity 181, which can serve as a heat cavity of the housing 100. The second cavity 182 can be separated from the first cavity 181 by the partition 160. The housing 100 also includes a second air inlet and a second air outlet arranged in communication with the second cavity 182. The air conditioner unit also includes a condenser 230 and a heat dissipation fan, both of which are installed in the second cavity 182. The heat dissipation fan can drive the gas outside the housing 100 to enter the second cavity 182 from the second air inlet, and then flow out of the second air outlet to the outside after flowing through the condenser 230.

[0064] The electric control box 500 is installed in the first cavity 181 and electrically connected to the air conditioner unit. The air conditioner unit also includes a compressor, and the electric control box 500 is electrically connected to the air supply fan 220, the heat dissipation fan, and the compressor to control the operation of the air conditioner unit.

[0065] It is worth mentioning that the kitchen air conditioner also includes a hood unit 400, which includes an exhaust fan and an exhaust duct. The electric control box 500 is also electrically connected to the exhaust fan to control the operation of the hood unit 400.

[0066] In the flow direction of the gas in the first cavity 181, the electric control box 500 is located downstream of the evaporator 210. It can be understood that the gas is cooled after flowing through the evaporator 210, and can carry away the heat of the electric control box 500 when flowing through the electric control box 500 to cool the electric control box 500.

[0067] The kitchen air conditioner provided by the embodiment sets the evaporator 210, the air supply fan 220, and the electric control box 500 in the first cavity 181 of the housing 100. The air supply fan 220 can drive the gas to enter the first cavity 181 from the first air inlet 1811 and flow out of the first cavity 181 from the first air outlet 1812. In the flow direction of the gas in the first cavity 181, the electric control box 500 is located downstream of the evaporator 210. In this way, the gas flowing in the first cavity 181 can carry away the heat generated by the electric control box 500 after being cooled by the evaporator 210, avoiding overheating of the electric control box 500 and ensuring the service life of the electric control box 500.

[0068] In one embodiment, as Figures 1-3As shown, the air inlet end of the evaporator 210 is in communication with the first air inlet 1811. Illustratively, the first air inlet 1811 is provided on the top plate of the housing 100, the air inlet end of the evaporator 210 is located at the top end of the evaporator 210, the top end of the evaporator 210 is connected to the top plate of the housing 100, and the air inlet end of the evaporator 210 is arranged opposite to the first air inlet 1811. Wherein, the shape and size of the air inlet end of the evaporator 210 are matched with the first air inlet 1811. The above arrangement can ensure that the gas enters the first cavity 181 from the first air inlet 1811 first passes through the evaporator 210 for cooling.

[0069] Along the height direction of the kitchen air conditioner, the air supply fan 220 is located below the evaporator 210, and the electric control box 500 is located below the air supply fan 220. When the air supply fan 220 drives the airflow to flow in the first cavity 181, at least part of the airflow can flow through the electric control box 500 to carry away the heat of the electric control box 500.

[0070] Through the above arrangement, along the flow direction of the gas in the first cavity 181, the electric control box 500 is located downstream of the evaporator 210, and the gas flowing in the first cavity 181 can carry away the heat generated by the electric control box 500.

[0071] As shown in Figures 1-3 , the housing 100 includes a front panel 110. It can be understood that the front panel 110 is located on the front side of the housing 100, which can cover the first cavity 181 of the housing 100.

[0072] The first air outlet 1812 is arranged on the front panel 110 and arranged opposite to the air supply fan 220. Illustratively, the air supply fan 220 can be connected to the front panel 110, and the air outlet end of the air supply fan 220 faces the first air outlet 1812. In a possible implementation, a turbofan can be used as the air supply fan 220, and the air inlet end of the turbofan faces the inside of the first cavity 181.

[0073] In this structure, the air supply fan 220 can directly blow the gas in the first cavity 181 out of the first air outlet 1812 to drive the flow of the gas in the first cavity 181, and in turn drive the gas flowing through the evaporator 210 to cool the electric control box 500.

[0074] In an embodiment, as shown in Figure 2 , Figure 3 and Figures 5-7 , the electric control box 500 includes a box body 510 and a circuit board assembly. The box body 510 has a containing cavity 511, and the circuit board assembly is installed in the containing cavity 511. It can be understood that the box body 510 of the electric control box 500 can protect the circuit board assembly, and the air conditioner unit and the range hood unit 400 of the kitchen air conditioner can be controlled through the circuit board assembly.

[0075] The box body 510 is provided with a through hole 5124 which communicates the accommodating cavity 511 and the first cavity 181. The number of the through hole 5124 can be one or multiple, and the cross-sectional shape of the through hole 5124 can be rectangular, square, circular or other suitable shape, which is not limited herein.

[0076] Those skilled in the art can understand that the circuit board assembly inside the box body 510 will generate heat during the operation of the electric control box 500. By providing the through hole 5124 on the box body 510, the heat generated by the circuit board assembly can flow out of the accommodating cavity 511 of the box body 510 through the through hole 5124, improving the cooling effect of the electric control box 500, and further improving the reliability of the electric control box 500.

[0077] In one possible implementation, as shown in Figure 5 Figure 6 and Figure 8 , a water blocking piece 515 can be installed in the through hole 5124, so that the condensed water outside the electric control box 500 is not easy to flow into the box body 510. The water blocking piece 515 can be provided with a slit which penetrates the water blocking piece 515, and the gas can pass through the water blocking piece 515 through the slit.

[0078] In one specific embodiment, as shown in Figures 5-7 , the electric control box 500 further comprises a bracket 530, which is installed in the accommodating cavity 511, and the bracket 530 divides the accommodating cavity 511 into a first cavity 5111 and a second cavity 5112.

[0079] Specifically, the bracket 530 can be installed in the middle of the accommodating cavity 511, and the space on one side of the bracket 530 in the accommodating cavity 511 is the first cavity 5111, and the space on the other side of the bracket 530 in the accommodating cavity 511 is the second cavity 5112. For example, the bracket 530 can be a plate-like structure which can be installed in the interior of the accommodating cavity 511 by fastening, and the first cavity 5111 and the second cavity 5112 are respectively located on the opposite sides of the plate-like structure.

[0080] ​The circuit board assembly further comprises a first circuit board 521 and a second circuit board 522, the first circuit board 521 is located in the first chamber 5111 and connected with the bracket 530, and the second circuit board 522 is located in the second chamber 5112 and connected with the bracket 530. It can be understood that the first circuit board 521 and the second circuit board 522 are respectively installed on the two opposite sides of the bracket 530. In a possible implementation, the first circuit board 521 can be used to control the air conditioning unit of the kitchen air conditioner, and the second circuit board 522 can be used to control the hood unit 400 of the kitchen air conditioner. The first circuit board 521 and the second circuit board 522 can be respectively fixed on the bracket 530 by fastening.

[0081] A part of the through holes 5124 are in communication with the first chamber 5111, and a part of the through holes 5124 are in communication with the second chamber 5112. That is to say, the number of the through holes 5124 on the box body 510 is at least two, at least one through hole 5124 is in communication with the first chamber 5111 and the first cavity 181, and at least one through hole 5124 is in communication with the second chamber 5112 and the first cavity 181.

[0082] In this structure, the heat generated by the first circuit board 521 can flow out of the containing cavity 511 of the box body 510 through the through holes 5124 in communication with the first chamber 5111, and the heat generated by the second circuit board 522 can flow out of the containing cavity 511 of the box body 510 through the through holes 5124 in communication with the second chamber 5112, thereby avoiding damage caused by excessively high temperature of the first circuit board 521 or the second circuit board 522, and further improving the reliability of the electric control box 500.

[0083] In a more specific embodiment, as shown in Figures 5-8 The box body 510 has a first side plate 5113 and a second side plate 5114 arranged oppositely, and the first side plate 5113 and the second side plate 5114 are respectively provided with through holes 5124.

[0084] Illustratively, the box body 510 comprises a box portion 512 and a first cover 513 arranged on the box portion 512, and the first side plate 5113 and the second side plate 5114 are two side plates of the box portion 512 arranged oppositely. The number of the through holes 5124 on the first side plate 5113 and the second side plate 5114 is non-limiting, for example, one, two or three, and is not uniquely limited herein.

[0085] In this structure, the gas outside the box body 510 can flow into the inside of the box body 510 through the through holes 5124 on one of the first side plate 5113 and the second side plate 5114, and flow out of the box body 510 through the through holes 5124 on the other of the first side plate 5113 and the second side plate 5114, so that the gas flows more smoothly in the box body 510, which is conducive to improving the heat dissipation efficiency of the electric control box 500.

[0086] It is worth mentioning that the box body 510 can be provided with the through hole 5124 on the remaining wall plates in addition to the first side plate 5113 and the second side plate 5114, which is not limited herein.

[0087] In a possible implementation, the bracket 530 is provided with a communication part between the opposite side walls of the box body 510, and the communication part communicates the first chamber 5111 and the second chamber 5112.

[0088] In a possible implementation, the bracket 530 can be spaced apart from the first side plate 5113 and the second side plate 5114, respectively, and the spacing between the first side plate 5113 and the bracket 530 and the spacing between the second side plate 5114 and the bracket 530 define the communication part.

[0089] In another possible implementation, the box body 510 further includes a third side wall and a fourth side wall arranged oppositely, and the third side wall and the fourth side wall are located between the first side plate 5113 and the second side plate 5114. One end of the bracket 530 is provided with a communication part between the third side wall, and the other end of the bracket 530 is provided with a communication part between the fourth side wall. The communication part can also be the spacing between the bracket 530 and the side wall of the box body 510.

[0090] The first chamber 5111 and the second chamber 5112 are communicated through the communication part, and when the gas outside the box body 510 enters the containing cavity 511 of the box body 510 through the through hole 5124 on one of the first side plate 5113 and the second side plate 5114, the gas can enter the first chamber 5111 and the second chamber 5112, respectively, through the communication part to cool the first circuit board 521 and the second circuit board 522, respectively. In addition, the through hole 5124 on the other of the first side plate 5113 and the second side plate 5114 can discharge the gas in the first chamber 5111 and the gas in the second chamber 5112 through the communication part.

[0091] Through the above arrangement, the first chamber 5111 and the second chamber 5112 are communicated through the communication part, and the gas flowing into the box body 510 from the through hole 5124 on one of the first side plate 5113 and the second side plate 5114 can enter the first chamber 5111 and the second chamber 5112, respectively, and the gas in the first chamber 5111 and the second chamber 5112 can flow out of the box body 510 from the through hole 5124 on the other of the first side plate 5113 and the second side plate 5114, so that the number of the respective through holes 5124 on the first side plate 5113 and the second side plate 5114 can be reduced, which is conducive to ensuring the structural strength of the box body 510, the number of the through holes 5124 on the box body 510 is reduced, and the electric control box 500 is not easy to be damaged by water.

[0092] In a specific embodiment, as Figures 5-8As shown, a through hole 5124 is formed on the first side plate 5113 and the second side plate 5114 respectively.
