[0081] Embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numbers represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0082] Reference will be made to Figures 1-29 The kitchen air conditioner 100 according to the embodiments of the present application is described below.

[0083] As Figures 1-6 shown, the kitchen air conditioner 100 according to the embodiments of the present application has a first air inlet 101, a first air outlet 102, a second air inlet 103 and a second air outlet 104.

[0084] The kitchen air conditioner 100 comprises a base plate 13 and a first unit 100a connected above the base plate 13. The first unit 100a comprises a first heat exchanger 3 and a first fan 2 for driving the air entering the first unit 100a from a first air inlet 101 to flow through the first heat exchanger 3 and discharged from a first air outlet 102 outside the first unit 100a.

[0085] The kitchen air conditioner 100 further comprises a second unit 100b connected above the base plate 13. That is, the first unit 100a and the second unit 100b are both mounted on the base plate 13, so that the kitchen air conditioner 100 forms an integrated air conditioner, which can realize efficient production and rapid installation.

[0086] The second unit 100b comprises a compressor 6, a second heat exchanger 5 and a second fan 4. The compressor 6 is connected with the first heat exchanger 3 and the second heat exchanger 5 to drive the refrigerant to circulate between the first heat exchanger 3 and the second heat exchanger 5. The second fan 4 is used to drive the air entering the second unit 100b from a second air inlet 103 to flow through the second heat exchanger 5 and discharged from a second air outlet 104 outside the second unit 100b.

[0087] In the cooling mode of the kitchen air conditioner 100, the first heat exchanger 3 acts as an evaporator, and the second heat exchanger 5 acts as a condenser. When the refrigerant flows through the first heat exchanger 3, it evaporates and absorbs the heat of the air flowing through the first unit 100a. When the refrigerant flows through the second heat exchanger 5, it releases heat to the air flowing through the second unit 100b and condenses. In this way, the temperature of the air flowing through the first unit 100a is reduced, and the air delivered from the first air outlet 102 of the first unit 100a to the indoor is cold air. Correspondingly, the temperature of the air flowing through the second unit 100b is increased, and the air delivered from the second unit 100b to the outdoor is hot air.

[0088] The first unit 100a and the second unit 100b are arranged in a first direction, and the base plate 13, the first unit 100a and the second unit 100b define a yielding through slot 14 with an opening facing upward, so that the joist 1100 is provided through the yielding through slot 14. The yielding through slot 14 is provided along a second direction, and the second direction is perpendicular to the first direction and both are horizontal directions. The first direction is the X direction shown in Figure 1 , and the second direction is the Y direction shown in Figure 1 .

[0089] For the convenience of understanding, if the first direction is defined as the front-rear direction, the second direction is defined as the left-right direction, the first unit 100a and the second unit 100b are arranged in the front-rear direction, and the accommodation slot 14 is actually a slot with a left opening, a right opening and an upper opening, in the process of installing the kitchen air conditioner 100 from bottom to top, the kitchen air conditioner 100 can avoid the keel 1100 through the accommodation slot 14, so that the keel 1100 is arranged in the accommodation slot 14.

[0090] Generally, as shown in Figure 7 The ceiling 1000 includes a keel 1100 as a support structure, and a plurality of spliced decorative plates 1200 installed on the keel 1100. The plurality of spliced decorative plates 1200 are connected to the keel 1100 and are arranged in a matrix shape, and the ceiling 1000 appears to be a horizontally arranged flat plate from a visual perspective.

[0091] The keel 1100 includes a plurality of first keels 1101 arranged in parallel and located on the same horizontal plane, and adjacent two first keels 1101 are spaced apart. The distance between adjacent two first keels 1101 is the same. In other schemes, the keel 1100 further includes a plurality of second keels 1102 extending in a direction perpendicular to the first keels 1101. Adjacent two second keels 1102 are spaced apart. The distance between adjacent two second keels 1102 is the same. The plurality of first keels 1101 and the plurality of second keels 1102 are configured as a mesh structure, and each spliced decorative plate 1200 covers a mesh hole in the mesh structure. The fixing manner of the keel 1100 on the wall is not limited here, and in some schemes, the end of the keel 1100 is fixed on the wall, and the roof of the kitchen is provided with a hoisting structure, and the keel 1100 is fixed on the hoisting structure, so that the whole ceiling 1000 is hoisted.

[0092] According to the prior art, when the kitchen air conditioner is installed, the body needs to be installed first, and then the ceiling is installed, or the ceiling is installed with part of the keel first, and then the body is hoisted, and the remaining keel and spliced decorative plate are installed, which cannot realize efficient installation. When the kitchen air conditioner needs to be cleaned or maintained, at least part of the spliced decorative plate needs to be removed, and if the machine needs to be disassembled for maintenance, the keel of the ceiling also needs to be removed, which leads to that the cleaning and maintenance of the kitchen air conditioner are very time-consuming and laborious, and the operation is complicated.

[0093] In the technical scheme, the first unit 100a, the second unit 100b and the bottom plate 13 are provided with the clearance slot 14, the clearance slot 14 is used for passing the first keel 1101 or the second keel 1102, and during installation of the kitchen air conditioner 100, the upper opening of the clearance slot 14 is aligned with the first keel 1101 below the ceiling 1000, then the height of the kitchen air conditioner 100 is lifted to make the first keel 1101 enter the clearance slot 14, until the first keel 1101 is located at the bottom of the clearance slot 14, finally the kitchen air conditioner 100 is fixed, and the installation is completed, and the installed keel 1100 does not need to be disassembled during installation of the kitchen air conditioner 100.

[0094] After the kitchen air conditioner 100 is installed, the first unit 100a and the second unit 100b can be hidden in the space above the ceiling 1000, and only the panel below the bottom plate 13 is exposed on the lower surface of the ceiling 1000, so that the installed kitchen air conditioner 100 is more beautiful. Accordingly, when the kitchen air conditioner 100 needs to be repaired, the kitchen air conditioner 100 can be disassembled by removing the fixing of the kitchen air conditioner 100 and vertically lowering the height of the kitchen air conditioner 100, and the installed keel 1100 does not need to be disassembled during disassembly of the kitchen air conditioner 100, effectively reducing the repair steps and time, and improving the maintenance efficiency.

[0095] Therefore, according to the kitchen air conditioner 100, the clearance slot 14 with the upward opening is defined by the first unit 100a, the second unit 100b and the bottom plate 13, on the one hand, during installation of the kitchen air conditioner 100, the installed keel 1100 does not need to be disassembled, the installation efficiency of the kitchen air conditioner 100 can be improved, and on the other hand, during cleaning or maintenance of the kitchen air conditioner 100, the keel 1100 of the ceiling 1000 does not need to be disassembled, the maintenance steps and time can be effectively reduced, the maintenance efficiency is improved, and the use experience of the user is improved.

[0096] According to some embodiments of the present application, the bottom plate 13 comprises a bottom plate body and a first shielding piece (not shown in the figure), and the first shielding piece is connected to the bottom plate body and the side of the first unit 100a facing the second unit 100b.

[0097] Specifically, the first machine group 100a and the second machine group 100b are arranged on the upper surface of the chassis body in the first direction, the first shielding member is connected with the region between the first machine group 100a and the second machine group 100b of the chassis body, and the first shielding member is also connected with the side of the first machine group 100a facing the second machine group 100b. In this way, the first shielding member can not only shield the connection between the chassis body and the first machine group 100a to achieve the function of hiding the connection, but also further connect the chassis body and the first machine group 100a to improve the connection reliability of the two.

[0098] The first shielding member can extend along the second direction and form an overall structural member with two ends close to the two ends of the first machine group 100a in the second direction. Of course, the number of the first shielding members can also be multiple, and the multiple first shielding members are arranged in the second direction and assembled together.

[0099] According to some embodiments of the present application, the chassis 13 comprises a chassis body and a second shielding member (not shown in the figure), and the second shielding member is connected with the chassis body and the side of the second machine group 100b facing the first machine group 100a.

[0100] Specifically, the first machine group 100a and the second machine group 100b are arranged on the upper surface of the chassis body in the first direction, the second shielding member is connected with the region between the first machine group 100a and the second machine group 100b of the chassis body, and the second shielding member is also connected with the side of the second machine group 100b facing the first machine group 100a. In this way, the second shielding member can not only shield the connection between the chassis body and the second machine group 100b to achieve the function of hiding the connection, but also further connect the chassis body and the second machine group 100b to improve the connection reliability of the two.

[0150] In the above technical solution, by arranging the electric control box 2a at the side of the first fan 2 away from the second air outlet 104 in the second direction, the electric control box 2a is arranged close to the compressor 6, the distance between the electric control box 2a and the compressor 6 in the second direction is reduced, so that the length of the wire between the electric control box 2a and the compressor 6 can be reduced, which can reduce the material cost on the one hand and facilitate wiring on the other hand.

[0151] As shown in the drawings, Figure 20 In some embodiments, the first heat exchanger 3 includes a first heat exchange part 31 and a second heat exchange part 32 connected in series, the first heat exchange part 31 extends in the second direction and is arranged opposite to the first fan 2 in the first direction, and the second heat exchange part 32 extends in the first direction and is located between the electric control box 2a and the first fan 2 in the second direction.

[0152] Therefore, by arranging the first heat exchanger 3 to include the first heat exchange part 31 and the second heat exchange part 32 connected in series, the contact area between the first heat exchanger 3 and the air can be increased, and the heat exchange efficiency can be improved; by arranging the second heat exchange part 32 between the electric control box 2a and the first fan 2, the air flow can pass through the electric control box 2a while flowing into the second heat exchange part 32, so that the heat of the electric control box 2a can be taken away, and the working performance of the electric control box 2a can be improved.

[0153] As shown in the drawings, Figure 20 In some embodiments, the first heat exchanger 3 further includes a third heat exchange part 33, the third heat exchange part 33 and the second heat exchange part 32 are arranged opposite to each other in the second direction, and the first heat exchange part 31 is connected between the second heat exchange part 32 and the third heat exchange part 33. That is, the first heat exchanger 3 is configured in a U shape. The first heat exchange part 31 and the second heat exchange part 32, and the first heat exchange part 31 and the third heat exchange part 33 can be connected by a circular arc transition.

[0154] In the above technical solution, by configuring the first heat exchanger 3 in a U shape, the contact area with the air is large and the heat exchange efficiency is high, the first fan 2 can be arranged in the internal cavity enclosed by the first heat exchanger 3 and the first partition plate 114, the layout is compact, and the first cavity 110 can be correspondingly reduced, so that the overall volume of the kitchen air conditioner 100 is small.

[0155] As shown in the drawings, Figures 16-18As shown, in some embodiments, the chassis 13 is provided with a water collecting groove 134, a water hitting groove 136 and a water leading groove 135. The water collecting groove 134 is located below the first heat exchanger 3. The water hitting groove 136 is located below the second heat exchanger 5. The water leading groove 135 is connected between the water collecting groove 134 and the water hitting groove 136.

[0156] Specifically, the chassis 13 is configured as a plate structure, which can be a flat plate. The chassis 13 can be configured as a substantially rectangular plate. One plate surface of the chassis 13 faces upward. The upward-facing plate surface of the chassis 13 is provided with a first area 131, a second area 133 and a connecting area 132. The first area 131 and the second area 133 are both rectangular areas. The connecting area 132 is arranged between the first area 131 and the second area 133. The connecting area 132 connects the first area 131 and the second area 133. The connecting area 132 can be configured as a straight strip, and the first area 131 and the second area 133 are located on opposite sides of the connecting area 132 in the width direction. The first air outlet 102 is arranged on the first area 131. The first air outlet 102 vertically penetrates the chassis 13.

[0157] The first unit 100a is arranged on the first area 131 of the chassis 13. The second unit 100b is arranged on the second area 133 of the chassis 13. The first unit 100a and the second unit 100b are arranged in the first direction with the spacing, and the gap 14 is located between the first unit 100a and the second unit 100b and above the connecting area 132.

[0158] The water collecting groove 134 is arranged on the first area 131 of the chassis 13 and below the first heat exchanger 3. The shape of the water collecting groove 134 can be the same as the shape of the projection of the first heat exchanger 3 on the chassis 13, for example, both are configured as a U shape. The water hitting groove 136 is arranged on the second area 133 of the chassis 13 and below the second heat exchanger 5. The height of the groove bottom of the water collecting groove 134 can be greater than or equal to the height of the groove bottom of the water hitting groove 136. The water leading groove 135 extends from the water collecting groove 134 to the water hitting groove 136. The water leading groove 135 connects the water collecting groove 134 and the water hitting groove 136. The water leading groove 135 can have a decreasing trend in the height of the groove bottom in the direction from the water collecting groove 134 to the water hitting groove 136.

[0159] The kitchen air conditioner 100 further comprises a water hitting assembly 7. For example, the water hitting assembly 7 can be arranged on the second area 133.

[0160] The water hitting assembly 7 comprises a water hitting wheel 71 and a water hitting motor 72. The water hitting wheel 71 at least partially extends into the water hitting groove 136. The water hitting motor 72 is drivingly connected to the water hitting wheel 71. The water hitting motor 72 is configured to drive the water hitting wheel 71 to rotate so that the water hitting wheel 71 throws the water in the water hitting groove 136 towards the second heat exchanger 5. The water hitting motor 72 is electrically connected to the electric control box 2a.

[0161] The water wheel 71 is configured in a substantially disc shape. The water wheel 71 is arranged above the bottom plate 13. The axis of the water wheel 71 is arranged horizontally, for example, the axis of the water wheel 71 extends along the first direction.

[0162] When the kitchen air conditioner 100 is running in the cooling mode, the temperature of the first heat exchanger 3 is lower than the temperature of the air flowing through the first unit 100a, the water vapor in the air is pre-cooled and condensed to the surface of the first heat exchanger 3 to form condensate water droplets. The condensate water droplets on the surface of the first heat exchanger 3 are subjected to the action of force and fall into the water collecting groove 134 to be collected. The condensate water in the water collecting groove 134 flows into the water wheel groove 136 along the water guide groove 135. Since the water wheel 71 extends into the water wheel groove 136, it can be in contact with the condensate water in the water wheel groove 136. When the water wheel 71 is driven to rotate by the water wheel motor 72, the condensate water in the water wheel groove 136 can be thrown onto the second heat exchanger 5. When the kitchen air conditioner 100 is running in the cooling mode, the surface temperature of the second heat exchanger 5 is relatively high, which can release heat to the condensate water to evaporate the condensate water. When the condensate water is evaporated, it absorbs the heat released by the second heat exchanger 5, thereby improving the heat exchange efficiency of the second heat exchanger 5, and further improving the energy efficiency of the kitchen air conditioner 100. At the same time, after the condensate water is evaporated, the water quantity of the condensate water in the water wheel groove 136 can be reduced, avoiding the overflow of the condensate water in the bottom plate 13, so that a drain pipe is not needed to guide the condensate water in the bottom plate 13 out of the kitchen air conditioner 100.

[0163] In an exemplary embodiment, the kitchen air conditioner 100 further comprises a water level switch 8. The water level switch 8 can be arranged in the water wheel groove 136, or arranged at one end of the water guide groove 135 close to the water wheel groove 136. The water level switch 8 can detect whether the water level in the water wheel groove 136 or the water guide groove 135 reaches a preset threshold. The water level switch 8 is configured to turn off the compressor 6 when it detects that the water level in the water wheel groove 136 or the water guide groove 135 reaches the preset threshold.

[0164] The preset threshold can be set to be slightly smaller than the water level height at which the water level switch 8 detects that the condensate water overflows from any one of the water wheel groove 136, the water collecting groove 134 and the water guide groove 135. When the water level in the water wheel groove 136 or the water guide groove 135 reaches the preset threshold, it indicates that there is a risk of condensate water overflowing from the water wheel groove 136, the water collecting groove 134 or the water guide groove 135. At this time, the compressor 6 is turned off, so that the rate of condensate water generated by the first heat exchanger 3 decreases, and at the same time the water wheel 71 continues to rotate to consume the condensate water that has been generated, which can prevent the condensate water from overflowing in the case of very high air humidity.

[0165] In an illustrative embodiment, a collection trough 137 is also provided on the chassis 13. The collection trough 137 is located below the second heat exchanger 5. The water-spraying trough 136 and the collection trough 137 are arranged sequentially in the direction of air flow within the second unit 100b, for example, sequentially arranged from the second air inlet 103 to the second air outlet 104. The extension directions of both the water-spraying trough 136 and the collection trough 137 can be perpendicular to the direction of air flow within the second unit 100b. The water-spraying trough 136 and the collection trough 137 are separated by a baffle. A through-hole 138 is provided on the baffle. The through-hole 138 can be configured as a through hole or a notch through the baffle. The location of the through-hole 138 can be higher than the bottom of the water-spraying trough 136. The through-hole 138 can be located in the middle vertical region of the baffle. The two ends of the through-hole 138 are connected to the collection tank 137 and the water-drawing tank 136, respectively.

[0166] In this way, after the water jet 71 throws out the condensate, some of the condensate droplets will be carried downstream by the airflow in the second cavity 120. At the same time, the condensate that has not been completely evaporated in the second heat exchanger 5 will also drip downwards. These condensate droplets will also be carried downstream by the airflow in the second unit 100b. Some of the condensate droplets that are deflected by the airflow will not fall back into the water jet 136, but will fall into the collection tank 137 and be collected. Then, they will flow back from the collection tank 137 into the water jet 136, preventing condensate from splashing onto other areas of the chassis 13 due to the wind force and causing condensate overflow.

[0167] In one illustrative embodiment, the body of the water pump 72 is located on the lower side of the second fan 4 and fixed to the chassis 13. In this embodiment, the second plate 415 is recessed into the first plate 414 to form a relief groove 4151, which is located on the lower side of the second fan 4, and the water pump body is disposed within the relief groove 4151. Positioning the body of the water pump 72 on the lower side of the second fan 4 fully utilizes the gap space between the second volute 416 of the second fan 4 and the chassis 13, making the structure of the kitchen air conditioner 100 more compact.

[0168] like Figure 20 As shown, in some embodiments, both the water pump motor 72 and the compressor 6 are located on the side of the second fan 4 away from the second air outlet 104 in the second direction. That is, both the water pump motor 72 and the compressor 6 are located close to the electrical control box 2a. This reduces the distance between the electrical control box 2a and the water pump motor 72 in the second direction, thereby reducing the length of the wires between the electrical control box 2a and the water pump motor 72. This reduces material costs and facilitates wiring.

[0169] In some embodiments, the first unit 100a comprises a first housing 11, the first housing 11 and the bottom plate 13 enclosing a first cavity 110, and the first heat exchanger 3 and the first fan 2 are arranged in the first cavity 110. Specifically, the first air inlet 101 can be arranged on the side wall of the first housing 11 away from the second housing 12, the bottom wall of the first cavity 110 is formed by the bottom plate 13, and the first air outlet 102 is arranged on the bottom wall of the first cavity 110. When the first fan 2 is working, it can drive air to enter the first cavity 110 from the side of the first housing 11, and drive the air in the first housing 11 to be transported downward of the first unit 100a.

[0170] As shown in Figure 19 , the electric control box 2a is at least partially exposed outside the first housing 11. In this way, on the one hand, the electric control box 2a can be directly disassembled from the outside of the first housing 11, which is beneficial to reduce the difficulty of subsequent maintenance, and on the other hand, the electric control box 2a can be directly in contact with the external air of the kitchen air conditioner 100, which is beneficial to heat dissipation of the electric control box 2a.

[0171] As shown in Figure 20 and Figure 21 , in some embodiments, the electric control box 2a comprises a shell 21a and a control panel 27a, the shell 21a defines a heat dissipation air duct 281 communicating with the upstream of the first cavity 110, and the side of the control panel 27a away from the first fan 2 has a wiring part and a heat sink 272, and the heat sink 272 is arranged in the heat dissipation air duct 281.

[0172] When the kitchen air conditioner 100 is running, indoor air can flow through the heat dissipation air duct 281 to flow to the first heat exchanger 3, and the airflow can be discharged from the first air outlet 102 after heat exchange with the first heat exchanger 3, and flow back to the indoor space to cool or heat the indoor space.

[0173] The side of the control panel 27a away from the first fan 2 has a wiring part and a heat sink 272, the wiring part can be connected to the first fan 2, the compressor 6 and the second fan 4 through wires, so that the shell 21a can control the first fan 2, the compressor 6 and the second fan 4 to work, and the heat sink 272 can be configured as a fin structure, and the heat sink 272 is arranged in the heat dissipation air duct 281, when the indoor air flows through the heat dissipation air duct 281, the heat sink 272 can exchange heat with the indoor air, so that the indoor air can cool the control panel 27a.

[0174] The shell 21a comprises a box body 211a and a box cover 212a, the box body 211a is arranged on the first housing 11 or the bottom plate 13 and loads the control panel 27a, and the box cover 212a covers the side of the control panel 27a away from the first fan 2.

[0175] Specifically, the box body 211a is provided with a mounting cavity with an open mouth, the control panel 27a is loaded in the mounting cavity, the wiring portion and the heat sink 272 of the control panel 27a are arranged opposite to the open mouth, and the box cover 212a is used for covering the side of the control panel 27a away from the first fan 2 to close the open mouth of the box body 211a, so as to close the control panel 27a between the box body 211a and the box cover 212a.

[0176] During installation, the box body 211a is connected with the first shell 11 first, then the control panel 27a is loaded in the mounting cavity of the box body 211a, then the connecting wire is extended into the mounting cavity from the open mouth to be connected with the wiring portion, and then the box cover 212a is covered on the side of the box body 211a away from the first fan 2, so that the assembly of the electric control box 2a is completed.

[0177] When the electric control box 2a needs to be repaired, the box cover 212a can be separated from the box body 211a, so that the wiring portion and the heat sink 272 can be exposed outward from the open mouth, so that the user can maintain the control panel 27a, and the practicability of the shell 21a is improved.

[0178] Therefore, by arranging the control panel 27a on the box body 211a, the control panel 27a can remain stationary during the disassembly and assembly of the box cover 212a, the connecting wire does not need to be reserved with excess length, the wiring difficulty can be reduced, the assembly difficulty of the electric control box 2a is reduced, the electric control box 2a is convenient for subsequent maintenance, and the practicability of the kitchen air conditioner 100 is improved.

[0179] As shown in FIG. Figure 19 In some embodiments, the box cover 212a is formed with a third air inlet 2122a, and the third air inlet 2122a is in communication with the heat dissipation air duct 281. The indoor air can flow into the heat dissipation air duct 281 through the third air inlet 2122a. It can be understood that the box cover 212a is relatively outward, easy to take in air, and easy to build a larger third air inlet 2122a, improve the ventilation volume, and improve the heat dissipation efficiency of the control panel 27a.

[0180] Of course, the utility model is not limited to this, the third air inlet 2122a can also be arranged on the box body 211a, and the box body 211a and the box cover 212a can also be arranged to jointly define the third air inlet 2122a. Therefore, different design requirements can be met.

[0181] In some embodiments, at least part of the third air inlet 2122a is arranged opposite to the heat sink 272. Therefore, the airflow flowing into the heat dissipation air duct 281 can directly dissipate heat for the heat sink 272, and the airflow path can be shortened, and the heat dissipation efficiency is improved.

[0182] In some embodiments, the first shell 11 comprises a first partition plate 114, a first plate member 112 and a second plate member 113, one end of the first partition plate 114 is connected with the bottom plate 13 and is arranged in the first direction away from the second unit 100b, the gap 14 is located between the first partition plate 114 and the second unit 100b, one end of the first plate member 112 is connected with the bottom plate 13, the first plate member 112 comprises a first side plate 1121 and a second side plate 1122 arranged at an angle, the first side plate 1121 and the first partition plate 114 are arranged opposite to each other in the first direction, one end of the second plate member 113 is connected with the bottom plate 13 and is arranged opposite to the second side plate 1122 in the second direction.

[0183] Wherein, one side of the second side plate 1122 is connected with the first side plate 1121, and the other side extends to the box body 211a. In this way, when the electric control box 2a is installed, the second side plate 1122 can be used to indicate or position, thereby improving the installation efficiency of the electric control box 2a.

[0184] As shown in Figure 19 , in some embodiments, the first side plate 1121 is provided with the first air inlet 101; and / or, the first side plate 1121 and the second plate member 113 have the first air inlet 101 therebetween.

[0185] Wherein, the second side plate 1122 is a closed plate and abuts against the box body 211a. In this way, during the operation of the kitchen air conditioner 100, the heat dissipation air duct 281 in the outer shell 21a can form a negative pressure state, so that more air can enter the heat dissipation air duct 281 from the third air inlet and flow towards the first heat exchanger 3, improving the heat dissipation efficiency of the electric control box 2a and thus improving the working performance of the electric control box 2a.

[0186] As shown in Figure 20 and Figure 21 , in some embodiments, the heat dissipation air duct 281 comprises a flow gap 2811 between the outer shell 21a and the heat sink 272, and a flow port 283 is formed on the box body 211a or between the box body 211a and the first shell 11, the flow port 283 communicates the first cavity 110 with the flow gap 2811, so that the heat dissipation air duct 281 is communicated upstream of the first cavity 110. Exemplarily, the flow port 283 can be formed on the box body 211a; or, the flow port 283 can be formed between the box body 211a and the first shell 11.

[0187] In this way, the flow direction of the airflow can be limited to make the airflow more stable, which is beneficial to reduce vortex and improve the stability of the airflow, thereby improving the heat dissipation efficiency.

[0188] The first shell 11 is provided with an opening 11a, and the box body 211a covers part of the opening 11a. An overflow gap 314 is formed between the edge of the opening 11a not covered by the box body 211a and the edge of the box body 211a. The box cover 212a covers the overflow gap 314, so that the overflow gap 314 is in communication with the indoor space through the heat dissipation air duct 281. In this way, the forming difficulty of the overflow gap 314 can be reduced, and the processing difficulty of the kitchen air conditioner 100 can be reduced.

[0189] As shown in Figure 20 and Figure 21 , the heat sink 272 includes a plurality of side surfaces arranged parallel to the length direction of the heat sink 272. A first side surface 2721 of the plurality of side surfaces is arranged towards the first ventilation heat exchange component, and the first side surface 2721 is used for heat exchange with related components (such as passive devices, etc.) on the electric control panel. A second side surface 2722 of the plurality of side surfaces is arranged towards the overflow gap 2811, and the second side surface 2722 is used for heat exchange with the air flow flowing to the overflow gap 2811.

[0190] In an exemplary embodiment, as shown in Figures 22-25 , the kitchen air conditioner 100 further includes an electric control box 2a and a throttling element. The electric control box 2a is connected to the first shell 11. The electric control box 2a can be connected to the second plate member 113.

[0191] The electric control box 2a includes a shell 21a, a control panel 27a, a heat dissipation bottom plate 22a, a heat dissipation cover plate 23a, and a cooling pipe 24a. The shell 21a is configured as a box-shaped structure. The shell 21a can be made of insulating material, such as plastic. The shell 21a is provided with a cavity. The control panel 27a is a logic control unit of the kitchen air conditioner 100.

[0192] The control panel 27a is arranged in the cavity of the shell 21a. The control panel 27a is a logic control unit of the kitchen air conditioner 100. A plurality of electrical elements are arranged on the control panel 27a. Some of the electrical elements can be chips. The electrical elements generate heat when working.

[0193] The heat dissipation bottom plate 22a is made of metal material, such as aluminum or aluminum alloy. The heat dissipation bottom plate 22a has good heat conduction performance. The heat dissipation bottom plate 22a can be configured as a rectangular plate. One plate surface of the heat dissipation bottom plate 22a abuts against the control panel 27a.

[0194] The heat dissipation cover plate 23a is made of metal material, such as aluminum or aluminum alloy. The heat dissipation cover plate 23a has good heat conduction performance. The heat dissipation cover plate 23a covers the plate surface of the heat dissipation bottom plate 22a away from the control panel 27a. The heat dissipation cover plate 23a and the heat dissipation bottom plate 22a enclose a cooling channel. In the embodiment, as shown in Figure 24 and Figure 25As shown, the heat dissipation bottom plate 22a is inwardly recessed towards the plate surface of the heat dissipation cover plate 23a to form a first recess 221a. The heat dissipation cover plate 23a is inwardly recessed towards the plate surface of the heat dissipation bottom plate 22a to form a second recess 231a. The first recess 221a and the second recess 231a have the same shape, and the first recess 221a and the second recess 231a are aligned with each other. The inner wall of the first recess 221a and the inner wall of the second recess 231a enclose a cooling channel.

[0195] The cooling pipe 24a can be made of metal material. The cooling pipe 24a can be a copper pipe or an aluminum pipe. The cooling pipe 24a has the same shape as the cooling channel. The cooling pipe 24a is arranged in the cooling channel and extends along the cooling channel. The outer diameter of the cooling pipe 24a is equal to the diameter of the cooling channel, and the outer wall of the cooling pipe 24a abuts against the inner wall of the cooling channel. The two ends of the cooling pipe 24a extend out of the heat dissipation cover plate 23a and the heat dissipation bottom plate 22a.

[0196] The throttling element can be an electronic expansion valve or a capillary tube. The throttling element can be arranged in the second cavity 120 and close to the compressor 6.

[0197] The compressor 6, the second heat exchanger 5, the cooling pipe 24a, the throttling element, and the first heat exchanger 3 are sequentially connected to form a refrigeration circuit. The outlet of the compressor 6 is connected to the inlet of the second heat exchanger 5 through a refrigerant pipe. The outlet of the second heat exchanger 5 is connected to one end of the cooling pipe 24a through a refrigerant pipe. The other end of the cooling pipe 24a is connected to the throttling element through a refrigerant pipe. The throttling element is further connected to the inlet of the first heat exchanger 3 through a refrigerant pipe. The outlet of the first heat exchanger 3 is connected to the inlet of the compressor 6 through a refrigerant pipe.

[0198] Thus, the control panel 27a of the kitchen air conditioner 100 generates heat during operation, and the heat is conducted to the heat dissipation base plate 22a. Some of the heat is directly conducted to the cooling pipe 24a, and the rest of the heat is first conducted to the heat dissipation cover plate 23a, and then conducted to the cooling pipe 24a. In the refrigeration mode, the compressor 6 compresses the refrigerant, and outputs the high-temperature and high-pressure refrigerant to the second heat exchanger 5. The refrigerant releases heat to the air flowing through the second cavity 120 when flowing through the second heat exchanger 5, and becomes low-temperature liquid refrigerant. The liquid refrigerant is transported to the cooling pipe 24a, and absorbs the heat on the heat dissipation base plate 22a and the heat dissipation cover plate 23a when flowing through the cooling pipe 24a, thereby taking away the heat generated by the control panel 27a from the electric control box 2a. After entering the throttling element, the throttling element throttles and depressurizes the liquid refrigerant to convert the refrigerant from liquid to gas-liquid mixed state. The gas-liquid mixed state refrigerant is transported to the first heat exchanger 3, absorbs heat from the air flowing through the first cavity 110, and evaporates into gas state. The gas state refrigerant returns to the compressor 6 to complete a cycle.

[0199] Thus, the refrigerant can take away the heat generated by the control panel 27a during the cycle, and the heat dissipation is fast, so that the temperature in the electric control box 2a does not become too high, and the electrical components on the control panel 27a can work stably at a suitable temperature. Meanwhile, the electric control box 2a has a simple structure, and is easy to assemble and disassemble.

[0200] In an exemplary embodiment, as shown in Figure 24 and Figure 25 , the cooling pipe 24a and the cooling channel are both configured in U shape. The U-shaped cooling pipe 24a has a large contact area with the heat dissipation base plate 22a and the heat dissipation cover plate 23a, and the heat conduction between the cooling pipe 24a and the heat dissipation base plate 22a and the heat dissipation cover plate 23a is faster, and the cooling effect is better. Meanwhile, the U-shaped cooling pipe 24a has a simple structure, and is easy to manufacture.

[0201] In an exemplary embodiment, the control panel 27a includes a circuit board 271a and a chip (not shown in the figure). The circuit board 271a is configured in a flat plate. The circuit board 271a can be a printed circuit board 271a. The chip is arranged on one plate surface of the circuit board 271a. The chip can be soldered on the circuit board 271a. The circuit board 271a is fixed on the shell 21a. The circuit board 271a and the shell 21a can be connected by screws.

[0202] As shown in Figure 24 and Figure 25As shown, the electric control box 2a further comprises an insulating support. The insulating support is made of insulating material. The insulating support can be configured as a rectangular plate structure. The insulating support is provided with a first through hole 214a. The first through hole 214a vertically penetrates the insulating support. One plate surface of the insulating support abuts against the circuit board 271a. The insulating support is connected to the circuit board 271a. The insulating support and the circuit board 271a can be connected by screws. The extending direction of the first through hole 214a is perpendicular to the plate surface of the circuit board 271a.

[0203] The heat dissipation bottom plate 22a is arranged on the side of the circuit board 271a away from the insulating support and is connected to the insulating support. The heat dissipation bottom plate 22a can cover the plate surface of the insulating support away from the circuit board 271a. One end of the first through hole 214a faces the circuit board 271a, and the other end of the first through hole 214a faces the heat dissipation bottom plate 22a. The chip of the control board 27a penetrates the first through hole 214a of the insulating support, and the surface of the chip away from the circuit board 271a abuts against the heat dissipation bottom plate 22a.

[0204] In this way, the heat dissipation bottom plate 22a is arranged on the side of the circuit board 271a away from the insulating support, and the insulating support separates the heat dissipation bottom plate 22a and the circuit board 271a of the control board 27a from each other, preventing the heat dissipation bottom plate 22a from directly contacting the circuit board 271a and causing short circuit of the circuit on the circuit board 271a. Meanwhile, the chip is the main heat source on the control board 27a, and the chip can contact the heat dissipation bottom plate 22a through the first through hole 214a, and the heat dissipation bottom plate 22a can conduct the heat generated by the chip to the cooling pipe 24a, avoiding excessive temperature of the chip.

[0205] In an exemplary embodiment, the side of the chip away from the circuit board 271a is provided with a positioning protrusion. The positioning protrusion can be configured as a circular truncated cone. The insulating support is provided with a positioning hole 215a, which can be a circular hole. The positioning protrusion of the chip extends into the positioning hole 215a of the insulating support.

[0206] The positioning protrusion of the chip and the positioning hole 215a of the insulating support cooperate with each other, and the alignment between the chip and the insulating support is more accurate.

[0207] In an exemplary embodiment, the electric control box 2a further comprises an insulating cover plate 26a. The insulating cover plate 26a is made of insulating material, which can be engineering plastic. The insulating cover plate 26a covers the side of the insulating support opposite to the circuit board 271a, and the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a are sandwiched between the insulating cover plate 26a and the insulating support. The insulating cover plate 26a and the insulating support enclose a mounting cavity, which accommodates the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a. In this embodiment, the insulating support is recessed towards the plate surface of the insulating cover plate 26a to form a first mounting groove 216a, and the heat dissipation bottom plate 22a is arranged in the first mounting groove 216a. The insulating cover plate 26a is recessed towards the plate surface of the insulating support to form a second mounting groove (not shown in the figure), and the heat dissipation cover plate 23a is arranged in the second mounting groove. The inner wall of the first mounting groove 216a and the inner wall of the second mounting groove enclose the mounting cavity that accommodates the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a.

[0208] In this way, the insulating support and the insulating cover plate 26a enclose a mounting cavity, and the heat dissipation bottom plate 22a, the heat dissipation cover plate 23a and the cooling pipe 24a are all arranged in the mounting cavity. The insulating support and the insulating cover plate 26a can be heat-insulated to seal the heat in the mounting cavity, so that most of the heat can only be output from the cooling pipe 24a to the outer shell 21a, preventing the temperature of other areas in the outer shell 21a from being too high.

[0209] In an exemplary embodiment, the insulating cover plate 26a and the insulating support are detachably connected. The insulating cover plate 26a and the insulating support can be snap-connected. The side wall of the insulating cover plate 26a is provided with a plurality of hooks 261a, which extend towards the insulating support. The side wall of the insulating support is provided with a plurality of protrusions, and the plurality of hooks 261a respectively hook the plurality of protrusions, thereby realizing the snap-connection between the insulating cover plate 26a and the insulating support.

[0210] The heat dissipation bottom plate 22a and the heat dissipation cover plate 23a are detachably connected. The heat dissipation bottom plate 22a and the heat dissipation cover plate 23a can be connected by screws.

[0211] In this way, the heat dissipation bottom plate 22a is connected with the heat dissipation cover plate 23a, and the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a can clamp the cooling pipe 24a, so that the gaps between the heat dissipation bottom plate 22a and the cooling pipe 24a and between the heat dissipation cover plate 23a and the cooling pipe 24a are as small as possible, and the heat transfer efficiency is improved. Meanwhile, the insulation cover plate 26a is connected with the insulation support, and can fix the heat dissipation bottom plate 22a, the cooling pipe 24a and the heat dissipation cover plate 23a. Since the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a are detachably connected and the insulation cover plate 26a and the insulation support are detachably connected, when overhauling, the insulation cover plate 26a and the insulation support can be first disassembled, and then the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a are disassembled, so that the cooling pipe 24a can be separated from other parts of the electric control box 2a, and the disassembly is more convenient.

[0212] In an illustrative embodiment, as shown in Figure 23 The box body 211a is detachably connected to the first shell 11 and is arranged outside the first shell 11. The box body 211a can be detachably connected to the outward side of the second plate member 113, i.e., the electric control box 2a is arranged on the outer side wall of the first shell 11. The bottom of the box body 211a can be provided with a plurality of hooks 20a, and the second plate member 113 is provided with a plurality of hook holes 1131. The hook holes 1131 penetrate through the second plate member 113. The plurality of hooks 20a are respectively hung on the second plate member 113 by penetrating through the plurality of hook holes 1131, so that the box body 211a can be hung on the second plate member 113 through the hooks 20a. A screw connection is further arranged between the second plate member 113 and the box body 211a. When it is needed to separate the box body 211a from the second plate member 113, only the screws connecting the second plate member 113 and the box body 211a need to be unscrewed, and then the box body 211a is lifted up to make the hooks 20a disengage from the hook holes 1131, so that the box body 211a can be disassembled.

[0213] The box cover 212a covers the box body 211a and encloses a cavity with the box body 211a. The box cover 212a is located on the side of the box body 211a away from the first shell 11. The box cover 212a is detachably connected to the box body 211a. The box body 211a and the box cover 212a can be screw-connected.

[0214] The control board 27a, the insulation support, the insulation cover plate 26a, the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a are all arranged in the cavity enclosed by the box cover 212a and the box body 211a. The circuit board 271a is connected to the side of the box body 211a facing the box cover 212a. The circuit board 271a and the box body 211a can be detachably connected, for example, screw-connected. The insulation support is arranged on the board surface of the circuit board 271a facing the box cover 212a.

[0215] In this way, when the electric control box 2a is disassembled for maintenance, the cover 212a can be dismounted from the shell 21a, the insulating cover plate 26a can be dismounted from the insulating support, the heat dissipation cover plate 23a can be dismounted from the heat dissipation bottom plate 22a, the cooling pipe 24a can be removed from the heat dissipation cover plate 23a, and finally the shell 21a can be dismounted from the first shell 11, which is convenient for dismounting. Meanwhile, the electric control box 2a is arranged outside the first shell 11, and is not affected by the temperature change in the first shell 11, which is more stable.

[0216] In an illustrative embodiment, as shown in Figure 23 the box body 211a of the electric control box 2a is arranged on the outer side wall of the first shell 11. The box body 211a or the cover 212a is provided with a first notch 2121a near the side wall of the chassis 13. The first notch 2121a can be arranged on the side of the cover 212a close to the box body 211a, and the opening of the first notch 2121a faces the box body 211a; or the first notch 2121a can be arranged on the side of the box body 211a close to the cover 212a, and the opening of the first notch 2121a faces the cover 212a. The two ends of the cooling pipe 24a can extend out of the shell 21a from the first notch 2121a. The compressor 6 and the throttling element are arranged on the side of the second heat exchanger 5 away from the electric control box 2a. The side of the second heat exchanger 5 away from the compressor 6 is close to the side wall of the second cavity 120.

[0217] As shown in Figure 26 the kitchen air conditioner 100 further comprises a first refrigerant pipe 91 and a second refrigerant pipe 92. The two ends of the first refrigerant pipe 91 are connected to the second heat exchanger 5 and one end of the cooling pipe 24a respectively. The two ends of the second refrigerant pipe 92 are connected to the other end of the cooling pipe 24a and the throttling element respectively. The first refrigerant pipe 91 and the second refrigerant pipe 92 extend along the upper surface of the chassis 13. The first refrigerant pipe 91 extends from the end of the second heat exchanger 5 close to the compressor 6 to the first area 131 of the chassis 13, then extends from the first area 131 to the groove bottom of the accommodation groove 14, extends along the groove bottom to the electric control box 2a, and finally extends to the bottom of the electric control box 2a to be connected to one end of the cooling pipe 24a. The second refrigerant pipe 92 extends from the throttling element to the first area 131 of the chassis 13, then extends from the first area 131 to the groove bottom of the accommodation groove 14, extends along the groove bottom to the electric control box 2a, and finally extends to the bottom of the electric control box 2a to be connected to the other end of the cooling pipe 24a.

[0218] Thus, when the electric control box 2a is disassembled, after the box cover 212a, the heat dissipation cover plate 23a and the insulating cover plate 26a are all disassembled, the cooling pipe 24a is exposed, and after the connection between the box body 211a and the first shell 11 is released, the box body 211a can be pulled out from the gap between the cooling pipe 24a and the first shell 11 by bending the cooling pipe 24a to the outside of the first shell 11, which is more convenient for disassembly. At the same time, the pipes in the first and second refrigerant pipes 91 and 92 along the groove bottom of the accommodation groove 14 make full use of the space of the groove bottom of the accommodation groove 14, reduce the space occupation of the first and second refrigerant pipes 91 and 92 to the first and second cavities 110 and 120, and make the kitchen air conditioner 100 more compact and the layout more reasonable. The first notch 2121a is arranged on the side of the shell 21a close to the bottom plate 13, and the two ends of the cooling pipe 24a extend out of the shell 21a from the first notch 2121a, which is convenient for connecting the first and second refrigerant pipes 91 and 92 extending along the bottom plate 13.

[0219] In an illustrative embodiment, as shown in Figure 26 the second heat exchanger 5 is arranged close to the compressor 6, and one end of the second heat exchanger 5 close to the compressor 6 is used for connecting the refrigerant pipe. That is, one end of the first refrigerant pipe 91 is connected to the end of the second heat exchanger 5 close to the compressor 6, and the refrigerant pipe adjacent to the compressor 6 is connected to the end of the second heat exchanger 5 close to the compressor 6. The end of the second heat exchanger 5 away from the compressor 6 is close to the side wall of the second cavity 120.

[0220] Thus, the end of the second heat exchanger 5 close to the compressor 6 is used for connecting the refrigerant pipe, so that the other end of the second heat exchanger 5 can be as close to the side wall of the second cavity 120 as possible, thereby making the kitchen air conditioner 100 more compact. At the same time, since the end of the second heat exchanger 5 close to the compressor 6 is used for connecting the refrigerant pipe, and all the U-shaped heat exchange pipes 51 are arranged at the other end of the second heat exchanger 5, the processing difficulty of the second heat exchanger 5 can be reduced.

[0221] In an illustrative embodiment, as shown in Figure 16 the kitchen air conditioner 100 further comprises a protective cover. The protective cover can be configured as a straight strip, and the protective cover covers the groove bottom of the accommodation groove 14. The protective cover is connected to the first shell 11, and the connection between the protective cover and the first shell 11 can be a buckle connection or a screw connection. The protective cover and the groove bottom of the accommodation groove 14 form a pipe laying channel. At least a part of the first refrigerant pipe 91 and at least a part of the second refrigerant pipe 92 extend along the pipe laying channel.

[0222] Thus, the protective cover can separate the keel 1100 in the accommodation slot 14 from the first and second refrigerant pipes 91 and 92, and prevent the first and second refrigerant pipes 91 and 92 from being damaged by the keel 1100.

[0223] In an exemplary embodiment, the kitchen air conditioner 100 further comprises a weak current cable, a strong current cable and a first wire arrangement la. One end of the strong current cable and the weak current cable are connected to the control panel 27a of the electric control box 2a, and the other end of the strong current cable and the weak current cable are used to connect to the electric devices controlled by the electric control box 2a. The weak current cable transmits a low voltage, for example, below V. The strong current cable transmits a high voltage, for example, above V.

[0224] As shown in Figure 28 The first wire arrangement la is made of an insulating material, for example, plastic, and has insulation. The first wire arrangement la is arranged in the first cavity 110 of the first shell 11. One end of the first wire arrangement la is close to the electric control box 2a. The first wire arrangement la is provided with a first wire slot 11a and a second wire slot 12a. The first wire slot 11a and the second wire slot 12a are arranged side by side. One end of the first wire slot 11a and the second wire slot 12a is close to the electric control box 2a. After the weak current cable extends out of the electric control box 2a, at least a part of the weak current cable is arranged along the first wire slot 11a. After the strong current cable extends out of the electric control box 2a, at least a part of the strong current cable is arranged along the second wire slot 12a.

[0225] Thus, at least a part of the weak current cable is arranged in the first wire slot 11a of the first wire arrangement la, at least a part of the weak current cable is arranged in the first wire slot 11a of the first wire arrangement la, and the first wire arrangement la separates the part of the weak current cable from the part of the strong current cable, preventing the strong current cable and the weak current cable from being electrically connected. At the same time, the weak current cable and the strong current cable can be arranged by being inserted into the first wire slot 11a and the second wire slot 12a respectively, which can improve the assembly efficiency and quickly and safely disassemble the weak current cable and the strong current cable from the first wire arrangement la during maintenance.

[0226] In an exemplary embodiment, the first wire arrangement la is configured in a strip shape. The first wire arrangement la can be configured in an L-shaped structure. The first wire arrangement la can extend from the top of the second plate 113 to the top of one end of the partition plate, and then extend from the top of one end of the partition plate to the middle of the top of the partition plate. The first wire slot 11a and the second wire slot 12a both extend along the first wire arrangement la from one end of the first wire arrangement la to the other end of the first wire arrangement la.

[0227] In this way, the first wiring member 1a is configured in a strip shape, and the first wiring groove 11a and the second wiring groove 12a are both extended along the first wiring member 1a, so that the first wiring member 1a has a simpler structure and occupies a smaller space.

[0228] In an exemplary embodiment, the first wiring member 1a is provided with a first cable clamping portion 13a on the inner side wall of the first wiring groove 11a. The first cable clamping portion 13a can be configured in a flat plate shape, and the first cable clamping portion 13a is parallel to the groove bottom of the first wiring groove 11a. The first cable clamping portion 13a extends from one inner side wall to the other inner side wall of the first wiring groove 11a, and there is a gap between the first cable clamping portion 13a and the other inner side wall. There is a certain spacing between the first cable clamping portion 13a and the first wiring groove 11a, and the weak current cable passes through the space between the first cable clamping portion 13a and the groove bottom of the first wiring groove 11a. Since the weak current cable is pressed against the side of the groove bottom of the first wiring groove 11a by the first cable clamping portion 13a, it is difficult for the weak current cable to come out of the first wiring groove 11a.

[0229] In an exemplary embodiment, the first wiring member 1a is provided with a plurality of first cable clamping portions 13a, and the plurality of first cable clamping portions 13a are arranged in sequence along the first wiring groove 11a. The first cable clamping portion 13a can be provided with one, two first cable clamping portions 13a are respectively arranged at opposite ends of the first wiring groove 11a, and the remaining one first cable clamping portion 13a is arranged at the middle of the first wiring groove 11a.

[0230] The plurality of first cable clamping portions 13a can more stably fix the weak current cable in the first wiring groove 11a.

[0231] In an exemplary embodiment, the second wiring member 1b is provided with a second cable clamping portion 14a on the inner side wall of the second wiring groove 12a. The second cable clamping portion 14a can be configured in a flat plate shape, and the second cable clamping portion 14a is parallel to the groove bottom of the second wiring groove 12a. The second cable clamping portion 14a extends from one inner side wall to the other inner side wall of the second wiring groove 12a, and there is a gap between the second cable clamping portion 14a and the other inner side wall. There is a certain spacing between the second cable clamping portion 14a and the second wiring groove 12a, and the strong current cable passes through the space between the second cable clamping portion 14a and the groove bottom of the second wiring groove 12a. Since the strong current cable is pressed against the side of the groove bottom of the second wiring groove 12a by the second cable clamping portion 14a, it is difficult for the strong current cable to come out of the second wiring groove 12a.

[0232] In an exemplary embodiment, the first wiring member 1a is provided with a plurality of second cable clamping portions 14a, and the plurality of second cable clamping portions 14a are arranged in sequence along the second wiring groove 12a. The second cable clamping portion 14a can be provided with one, two second cable clamping portions 14a are respectively arranged at opposite ends of the second wiring groove 12a, and the remaining one second cable clamping portion 14a is arranged at the middle of the second wiring groove 12a.

[0233] The plurality of second clamping portions 14a can more firmly fix the strong electric cable in the second routing groove 12a.

[0234] In an illustrative embodiment, the first routing member 1a is disposed in the first cavity 110 of the first housing 11. The first routing member 1a is disposed above the first heat exchanger 3. The first routing groove 11a and the second routing groove 12a are disposed on the upward side of the first routing member 1a. The opening of the first routing groove 11a and the opening of the second routing groove 12a are upward. The top wall of the first cavity 110 of the first housing 11 covers the opening of the first routing groove 11a and the opening of the second routing groove 12a. In this embodiment, the top wall of the first cavity 110 of the first housing 11 is the first top plate 111.

[0235] In this way, since the first routing member 1a is disposed above the first heat exchanger 3, and the opening of the first routing groove 11a and the opening of the second routing groove 12a are upward, the weak electric cable and the strong electric cable can be arranged into the first routing groove 11a and the second routing groove 12a, respectively, very conveniently before the first top plate 111 is installed, which improves the assembly efficiency. Meanwhile, after the wiring is completed, the first top plate 111 is installed in place, and the first top plate 111 covers the opening of the first routing groove 11a and the opening of the second routing groove 12a, which can further prevent the weak electric cable and the strong electric cable from being pulled out of the first routing groove 11a and the second routing groove 12a, respectively.

[0236] In an illustrative embodiment, as shown in Figure 28 The kitchen air conditioner 100 further comprises a second routing member 3a. The second routing member 3a is configured in a strip shape, which can be a straight strip shape. The second routing member 3a is disposed in the second cavity 120 of the first housing 11. The second routing member 3a can be vertically disposed on the bottom plate 13. The second routing member 3a extends downward from the end of the first routing member 1a away from the electric control box 2a to the bottom plate 13. The upward top end of the second routing member 3a is connected to the end of the first routing member 1a away from the electric control box 2a, and the downward bottom end of the second routing member 3a is connected to the bottom wall of the first cavity 110, which is the bottom plate 13. The second routing member 3a and the first routing member 1a, and the second routing member 3a and the bottom plate 13 can be screw-connected.

[0237] The second routing member 3a is provided with a third routing groove 31a and a fourth routing groove 32a. The third routing groove 31a extends from the top end of the second routing member 3a to the bottom end of the second routing member 3a, and the third routing groove 31a vertically penetrates the second routing member 3a. The fourth routing groove 32a extends from the top end of the second routing member 3a to the bottom end of the second routing member 3a, and the fourth routing groove 32a vertically penetrates the second routing member 3a.

[0238] The top end of the third routing groove 31a of the second routing member 3a is close to the end of the first routing groove 11a of the first routing member 1a which is away from the electric control box 2a. At least a part of the weak current cable is routed along the third routing groove 31a.

[0239] The top end of the fourth routing groove 32a of the second routing member 3a is close to the end of the second routing groove 12a of the first routing member 1a which is away from the electric control box 2a. At least a part of the strong current cable is routed along the fourth routing groove 32a.

[0240] Thus, the weak current cable which extends out of the end of the first routing groove 11a of the first routing member 1a which is away from the electric control box 2a can enter into the third routing groove 31a of the second routing member 3a and extend downwardly along the third routing groove 31a to the bottom plate 13 and then extend along the bottom plate 13 to the electric devices, which can be the water punching motor 72, the water level switch 8, etc. The strong current cable which extends out of the end of the second routing groove 12a of the first routing member 1a which is away from the electric control box 2a can enter into the fourth routing groove 32a of the second routing member 3a and extend downwardly along the fourth routing groove 32a to the bottom plate 13 and then extend along the bottom plate 13 to the electric devices, which can be the first motor 23, the second motor 43 or the compressor 6.

[0241] In an exemplary embodiment, the third routing groove 31a is provided with a third cable clamping portion 33a on the inner side wall thereof. The third cable clamping portion 33a can be configured as a flat plate structure, and the third cable clamping portion 33a is parallel to the groove bottom of the third routing groove 31a. The third cable clamping portion 33a extends from one inner side wall of the third routing groove 31a to the other inner side wall, and there is a gap between the third cable clamping portion 33a and the other inner side wall. There is a certain spacing between the third cable clamping portion 33a and the third routing groove 31a, and the weak current cable passes through the space between the third cable clamping portion 33a and the groove bottom of the third routing groove 31a. Since the weak current cable is pressed against the side of the groove bottom of the third routing groove 31a by the third cable clamping portion 33a, it is difficult for the weak current cable to come out of the third routing groove 31a.

[0242] In an exemplary embodiment, the second routing member 3a is provided with a plurality of third cable clamping portions 33a which are arranged in sequence along the third routing groove 31a. The third cable clamping portion 33a can be provided one, two third cable clamping portions 33a are respectively provided at opposite ends of the third routing groove 31a, and the remaining third cable clamping portion 33a is provided at the middle of the third routing groove 31a.

[0243] The plurality of third cable clamping portions 33a can more stably fix the weak current cable in the third routing groove 31a.

[0244] In an exemplary embodiment, the fourth wire slot 32a is provided with a fourth wire clamping portion 34a on the inner side wall. The fourth wire clamping portion 34a can be configured as a flat plate structure, and the fourth wire clamping portion 34a is parallel to the bottom of the fourth wire slot 32a. The fourth wire clamping portion 34a extends from one inner side wall to the other inner side wall of the fourth wire slot 32a, and there is a gap between the fourth wire clamping portion 34a and the other inner side wall. There is a certain spacing between the fourth wire clamping portion 34a and the fourth wire slot 32a, and the strong current cable passes through the space between the fourth wire clamping portion 34a and the bottom of the fourth wire slot 32a. Since the strong current cable is pressed against the side of the bottom of the fourth wire slot 32a by the fourth wire clamping portion 34a, it is difficult for the strong current cable to come out of the fourth wire slot 32a.

[0245] In an exemplary embodiment, the fourth wire slot 32a is provided with a fourth wire clamping portion 34a on the inner side wall. The fourth wire clamping portion 34a can be configured as a flat plate structure, and the fourth wire clamping portion 34a is parallel to the bottom of the fourth wire slot 32a. The fourth wire clamping portion 34a extends from one inner side wall to the other inner side wall of the fourth wire slot 32a, and there is a gap between the fourth wire clamping portion 34a and the other inner side wall. There is a certain spacing between the fourth wire clamping portion 34a and the fourth wire slot 32a, and the strong current cable passes through the space between the fourth wire clamping portion 34a and the bottom of the fourth wire slot 32a. Since the strong current cable is pressed against the side of the bottom of the fourth wire slot 32a by the fourth wire clamping portion 34a, it is difficult for the strong current cable to come out of the fourth wire slot 32a.

[0246] The plurality of fourth wire clamping portions 34a can more stably fix the strong current cable in the fourth wire slot 32a.

[0247] In an exemplary embodiment, the second wire member 3a extends downward along the side wall of the first cavity 110, which can be a partition. The openings of the third wire slot 31a and the fourth wire slot 32a face the side wall of the first cavity 110, and the side wall of the first cavity 110 covers the third wire slot 31a and the fourth wire slot 32a. In this embodiment, the second wire member 3a extends downward from the middle of the top end of the partition to the middle of the bottom of the partition, and the partition covers the openings of the third wire slot 31a and the fourth wire slot 32a.

[0248] In this way, since the openings of the third wire slot 31a and the fourth wire slot 32a face the side of the partition, it is very convenient to arrange the weak current cable and the strong current cable into the third wire slot 31a and the fourth wire slot 32a, respectively, before the partition is installed, which improves the assembly efficiency. At the same time, after the wiring is completed, the partition is installed in place, and the partition covers the openings of the third wire slot 31a and the fourth wire slot 32a, which can further prevent the weak current cable and the strong current cable from coming out of the third wire slot 31a and the fourth wire slot 32a, respectively.

[0249] In some embodiments, the strong current cables include a first strong current cable, a second strong current cable and a third strong current cable. One end of the first strong current cable is connected to the first fan 2, and the other end is connected to the electric control box 2a.

[0251] As shown in Figure 20 According to some embodiments of the present application, in the air flow direction in the first unit 100a, the first heat exchanger 3 is located between the first air inlet 101 and the first fan 2, and in the air flow direction in the second unit 100b, the second heat exchanger 5 is located between the second air inlet 103 and the second fan 4.

[0252] The first heat exchanger 3 and the second heat exchanger 5 are oppositely arranged in the first direction, the first fan 2 is arranged on the side of the first heat exchanger 3 facing the second heat exchanger 5, and the second fan 4 is arranged on the side of the second heat exchanger 5 facing the first heat exchanger 3.

[0253] That is, the first heat exchanger 3 and the second heat exchanger 5 are away from each other in the first direction. Therefore, by arranging the first heat exchanger 3 and the second heat exchanger 5 in this way, the distance between them in the first direction can be increased, and the heat insulation effect can be achieved to prevent the first heat exchanger 3 and the second heat exchanger 5 from being disturbed by each other's temperature.

[0254] As shown in Figures 16-18As shown, in some embodiments, the chassis 13 is provided with a water collection tank 134, a water spraying tank 136, and a water intake tank 135. The water collection tank 134 is located below the first heat exchanger 3, the water spraying tank 136 is located below the second heat exchanger 5, and the water intake tank 135 connects the water collection tank 134 and the water spraying tank 136. The kitchen air conditioner 100 also includes a water spraying assembly 7, which includes: a water spraying wheel 71, which at least partially extends into the water spraying tank 136; and a water spraying motor 72, which is drivenly connected to the water spraying wheel 71. The water spraying motor 72 is configured to drive the water spraying wheel 71 to rotate so that the water spraying wheel 71 throws water in the water spraying tank 136 toward the second heat exchanger 5.

[0255] When the kitchen air conditioner 100 is running in cooling mode, the temperature of the first heat exchanger 3 is lower than the temperature of the air flowing through the first unit 100a. Water vapor in the air condenses on the surface of the first heat exchanger 3, forming condensate droplets. These droplets, under pressure, drip into the water collection tank 134 and are collected. The condensate in the water collection tank 134 flows along the water inlet trough 135 into the water jetting trough 136. Since the water jetting wheel 71 extends into the water jetting trough 136, it comes into contact with the condensate. When the water jetting motor 72 drives the water jetting wheel 71 to rotate, it can throw the condensate in the water jetting trough 136 onto the second heat exchanger 5. When the kitchen air conditioner 100 operates in cooling mode, the surface temperature of the second heat exchanger 5 is relatively high, which allows it to release heat to the condensate to evaporate it. As the condensate evaporates, it absorbs the heat released by the second heat exchanger 5, thereby improving the heat exchange efficiency of the second heat exchanger 5 and thus increasing the energy efficiency of the kitchen air conditioner 100. Simultaneously, the evaporation of the condensate reduces the amount of condensate in the drain pan 136, preventing overflow from the chassis 13. Therefore, there is no need to install a drain pipe to lead the condensate out of the kitchen air conditioner 100.

[0256] like Figure 29 As shown, according to some embodiments of the present invention, the upper surface of the chassis 13 has an installation area 130. The first unit 100a and the second unit 100b are located in the installation area 130. The installation area 130 is rectangular in shape, and the four corners of the installation area 130 have connecting lugs 130a for connecting with the lifting assembly. That is, the installation area 130 is the rectangular area occupied by the first unit 100a, the second unit 100b, and the four connecting lugs 130a.

[0257] Among them, such as Figure 29 As shown, the length of the installation area 130 is L1, and the width is L2, as follows. Figure 19 As shown, the height of the first unit 100a / the second unit 100b is H, 575mm≤L1≤590mm, 550mm≤L2≤565mm, 250mm≤H≤265mm.

[0258] For example, the length L1 of the installation area 130 can be 575mm, 580mm, 590mm, etc., the width L2 of the installation area 130 can be 550mm, 555mm, 560mm, 565mm, etc., and the height H of the first unit 100a / second unit 100b can be 250mm, 255mm, 260mm, 265mm, etc.

[0259] Generally, the ceiling 1000 includes a keel 1100 as a supporting structure and decorative panels 1200 installed on the keel 1100. Therefore, considering the size of the commonly used square decorative panels 1200, the kitchen air conditioner 100 proposed in this application typically requires the removal of four decorative panels 1200 during installation. In other words, the overall size of the kitchen air conditioner 100 proposed in this application, excluding the chassis 13 (including the first unit 100a and the second unit 100b), needs to be smaller than the area of ​​the four decorative panels 1200 so that the first unit 100a and the second unit 100b can be installed above the ceiling 1000. Based on this, the maximum volume of the kitchen air conditioner 100 excluding the chassis 13 can meet L1×L2×H of 590mm×565mm×265mm, and the minimum volume can meet L1×L2×H of 575mm×550mm×250mm, etc. Of course, the number of splicing decorative panels 1200 that need to be removed when installing the kitchen air conditioner 100 is not limited to four, but depends on the area and shape of each splicing decorative panel 1200.
