[0039] According to the embodiment of the present utility model, please combine Figure 1 , Figure 3 and Figure 6 As shown, a housing assembly 100 is proposed, the housing assembly 100 includes a housing 20 and an electric control box 40, the housing 20 has an upper chamber 21 and an exhaust port 2101, the exhaust port 2101 is connected to the upper chamber 21 and is used to install a fan 201, and the upper chamber 21 is used to install a heat exchanger 202. The electric control box 40 has an electric control cavity 411, the electric control cavity 411 is used to accommodate an electric control device 203, the electric control device 203 specifically refers to various electric control components in the variable frequency unit in the air conditioner 200, and the electric control device 203 includes an electric control main board, a filter board, a PTC (Positive Temperature Coefficient, referred to as PTC) heating tube, a temperature sensor, a module board, an inductor, etc. The electric control box 40 is also provided with an air inlet 412 and an air outlet 424 connected to the electric control chamber 411. The air outlet 424 is connected to the upper chamber 21, so that when the upper chamber 21 is in a negative pressure state, under the action of the suction force of the upper chamber 21, external air can flow into the electric control chamber 411 through the air inlet 412, and flow into the upper chamber 21 through the electric control chamber 411 and the air outlet 424.

[0040] According to the shell assembly 100 proposed in the utility model, an air inlet 412 and an air outlet 424 are arranged on the electric control box 40, and the electric control chamber 411 is connected with the upper chamber 21 through the air outlet 424. When negative pressure is generated in the upper chamber 21 based on the driving action of the fan 201, the external air flow can enter the electric control chamber 411 through the air inlet 412, and flow into the upper chamber 21 through the electric control chamber 411 and the air outlet 424. Therefore, the air flow velocity in the electric control chamber 411 can be effectively increased, and the heat dissipation efficiency of the electric control chamber 411 can be improved.

[0041] It should also be noted that, in this embodiment, the electric control chamber 411 itself forms an air duct for heat dissipation, and utilizes the negative pressure of the upper chamber 21, so there is no need to additionally set a fan 201 for heat dissipation on the electric control box 40, which has a simple structure and saves costs. In addition, when the air conditioner 200 is in the process of heating, the heat exchanger 202 arranged in the upper chamber 21 is an evaporator, and after the external air flow flows through the electric control chamber 411 to dissipate the heat of the electric control device 203 in the electric control chamber 411, the heat dissipated by the electric control device 203 can be replaced into the upper chamber 21, thereby improving the heat absorption capacity of the heat exchanger 202 in the upper chamber 21, and making full use of the heat energy generated by the electric control device 203.

[0042] In some embodiments, Figure 1 and Figure 3 As shown, the housing assembly 100 further includes a partition 30, which is disposed in the housing 20. The partition 30 is disposed in the horizontal direction and divides the internal space of the housing 20 into an upper chamber 21 and a lower chamber 22. The lower chamber 22 is used to accommodate the compressor, shell tubes and piping systems, etc., wherein the electric control box 40 is installed in the lower chamber 22 in the vertical direction, the air inlet 412 is disposed at the bottom of the electric control box 40, the air outlet 424 is disposed at the top of the electric control box 40, and the air outlet 424 on the electric control box 40 is connected to the bottom of the upper chamber 21. In this embodiment, the electric control box 40 takes in air from the bottom, and when passing through the electric control cavity 411, the air can be fully exchanged with the electric control device 203 disposed in the electric control cavity 411 and then discharged from the top of the electric control cavity 411, thereby increasing the travel of the airflow in the electric control cavity 411 and improving the heat dissipation capacity of the electric control cavity 411.

[0043] In some embodiments, Figure 4 , Figure 5 and Figure 6As shown, the electric control box 40 includes an electric control main shell 41 and an air duct shell 42. The electric control main shell 41 is a rectangular shell structure. The air duct shell 42 is arranged at the top of the electric control main shell 41, and the air duct shell 42 is located between the partition 30 and the electric control main shell 41. The electric control main shell 41 is hollow inside to define an electric control cavity 411. The air duct shell 42 defines an air flow channel 421 inside. The air outlet 424 is arranged at the top of the air duct shell 42 and communicates with the air flow channel 421. The electric control cavity 411 is communicated with the upper chamber 21 through the air flow channel 421. The airflow in the electric control cavity 411 first enters the air flow channel 421 and flows through the air flow channel 421, and then enters the upper chamber 21 from the air outlet 424. The air duct shell 42 is provided with a water leakage port 422, which is in communication with the air flow channel 421. When the condensed water in the upper chamber 21 drips from the air outlet 424 to the air flow channel 421, the condensed water can flow out of the air flow channel 421 from the water leakage port 422. Specifically, along the first direction, the water leakage port 422 is located on one side of the electric control cavity 411, thereby preventing the condensed water flowing out of the water leakage port 422 from dripping into the electric control cavity 411, and taking into account the waterproof function of the electric control box 40 while improving the heat dissipation performance of the electric control box 40 by utilizing the negative pressure of the upper chamber 21, so as to prevent the condensed water in the upper chamber 21 from flowing into the electric control cavity 411 through the air outlet 424. In this embodiment, the first direction is parallel to the horizontal direction, so that the water leakage port 422 and the electric control cavity 411 are arranged at intervals in the horizontal direction, and the condensed water can drip downward to the outside of the electric control cavity 411 through the water leakage port 422 under the action of gravity. Understandably, in other embodiments, the first direction is at an angle to the horizontal direction, that is, the water leakage port 422 may be located obliquely above the electric control cavity 411 , and the projection of the water leakage port 422 on the horizontal plane is located outside the projection of the electric control cavity 411 on the horizontal plane.

[0044] In some embodiments, please combine Figure 3 , Figure 4 and Figure 6 As shown, along the direction from the electric control main shell to the air duct shell, the air flow channel 421 includes an air inlet section 4211, a middle section 4212 and an air outlet section 4213 which are connected in sequence, and the middle section 4212 extends along a first direction, which is parallel to the horizontal direction, so that the airflow in the middle section 4212 flows along the horizontal direction, and the water leakage port 422 is located in the air outlet section 4213, and the water dripping into the air flow channel 421 through the air outlet 424 (such as water dripping or splashing on the middle section 4212) can flow to one side of the air outlet section 4213 under the blowing of the air flow, so that the water in the air flow channel 421 can be gathered to the water leakage port 422 under the push of the air flow, thereby further reducing the probability of condensed water flowing into the electric control cavity 411 through the air flow channel 421.

[0045] In some embodiments, please combine Figure 1 , Figure 4 and Figure 6As shown, along the second direction, the air outlet 424 and the water leakage port 422 are arranged opposite to each other, and the second direction is parallel to the vertical direction. The condensed water dripping from the air outlet 424 into the air flow channel 421 can flow out directly through the water leakage port 422 under the action of gravity, thereby improving the drainage efficiency of the air flow channel 421 and reducing the amount of condensed water accumulated in the air flow channel 421. In this embodiment, the water leakage port 422 is located directly below the air outlet 424, that is, the projections of the water leakage port 422 and the air outlet 424 on the horizontal plane at least partially overlap.

[0046] In some embodiments, the second direction forms an angle with the vertical direction, that is, the water leakage port 422 is located obliquely below the air outlet 424 . At this time, condensed water flowing into the air flow channel 421 from the air outlet 424 can still be discharged through the water leakage port 422 .

[0047] In some embodiments, please combine Figure 5 and Figure 6 As shown, a drainage groove 423 is provided inside the bottom of the airflow channel 421. Along the second direction, the drainage groove 423 is arranged opposite to the air outlet 424, so that the projections of the drainage groove 423 and the air outlet 424 on the horizontal plane at least partially overlap, and the condensed water dripping from the air outlet 424 into the airflow channel 421 can directly drip and gather to the bottom of the drainage groove 423 under the action of gravity, and be discharged from the water leakage port 422 provided on the bottom wall of the drainage groove 423. By providing the drainage groove 423, the condensed water flowing into the airflow channel 421 from the air outlet 424 can be gathered in the drainage groove 423, reducing the probability of overflowing to the electric control chamber 411 due to a large amount of water accumulated in the airflow channel 421. In this embodiment, the inner wall of the drainage groove 423 close to the air inlet section 4211 is inclined relative to the first direction, increasing the exposure of the drainage groove 423 toward the air outlet 424 and increasing the probability of condensed water dripping directly into the drainage groove 423, so as to more efficiently discharge the condensed water through the leakage port 422.

[0048] In some embodiments, Figure 4 As shown, at least one air guide plate 50 is further provided in the electric control cavity 411, and the electric control cavity 411 has a preset area 4111, and the preset area 4111 is used to place power elements, wherein the power elements refer to electronic components with relatively large heat generation, such as capacitors, PTC heating tubes, etc. The air guide plate 50 is provided on one side of the air inlet 412 and is inclined toward the preset area 4111, and the air guide plate 50 is provided with an air guide surface (not shown in the figure), which is arranged toward the preset area and is arranged at an acute angle to the opening direction of the air inlet, so that the airflow flowing into the electric control cavity 411 from the air inlet 412 is guided to the preset area 4111 under the action of the air guide surface, thereby increasing the heat dissipation capacity of the preset area 4111, thereby enhancing the heat dissipation effect of the preset area 4111 for the power elements.

[0049] In some embodiments, Figure 4 and Figure 5 As shown, the housing assembly 100 further includes a water baffle 60, which is an L-shaped plate-shaped member. The water baffle 60 includes a connecting portion 61 and a water baffle 62. The connecting portion 61 is connected to the outer wall of the electric control box 40, and the connecting portion 61 extends in the vertical direction. The water baffle 62 is arranged at a 90-degree angle with the connecting portion 61 and is located at one end of the connecting portion 61 away from the electric control chamber 411. The water baffle 62 is arranged opposite to the air inlet 412 in the vertical direction, and in the vertical direction, the water baffle 62 is located below the air inlet 412 and is spaced from the air inlet 412. The function of the water baffle 60 is to prevent water dripping from the upper side of the electric control box 40 to the placement surface from splashing into the air inlet 412, thereby achieving a waterproof effect on the lower part of the electric control box 40.

[0050] The installation surface refers to the surface where the housing assembly 100 is installed, such as the ground, roof plane, etc. The water dripping from the electric control box 40 includes condensed water dripping from the water leak 422 and condensed water and rainwater on the housing assembly 100 in the natural environment.

[0051] In some embodiments, the electric control box 40 is detachably connected to the partition 30, and the air outlet 424 can be detached from top to bottom through the electric control box 40, which is convenient for installation. There are multiple connection modes between the electric control box 40 and the partition 30. For example, in some embodiments, a mounting portion is provided on the partition 30, and a fixing hole is correspondingly provided on the electric control box 40. The fasteners penetrating the fixing hole are fastened to the mounting portion to realize the detachable connection between the electric control box 40 and the partition 30; in other embodiments, a mounting portion is provided on the electric control box 40, and a fixing hole is correspondingly provided on the partition 30.

The detachable connection between the electric control box 40 and the partition 30 is realized by the clamping of the buckle and the slot.

[0052] In some embodiments, please combine Figure 1 , Figure 2 and Figure 3As shown, the position of the partition 30 relative to the air outlet 424 is also provided with an opening (not shown in the figure), the contour of the opening matches the contour of the air outlet 424, and along the vertical direction, the opening is relative to and communicates with the air outlet 424. The airflow in the electric control chamber 411 flows into the upper chamber 21 through the air outlet 424 and the opening in turn. In this embodiment, the shell assembly 100 also includes a water shield 70, which is connected to the partition 30. The water shield 70 is a cover-like structure. The water shield 70 includes a top plate 71 and a side plate 72 arranged around the circumferential edge of the top plate. The side plate 72 is annular in structure as a whole and is covered outside the opening. The condensed water dripping from the evaporator to the partition 30 is blocked outside the opening by the side plate 72. The top plate 71 is used to directly block the water dripping from the evaporator, thereby further reducing the probability of the condensed water in the upper chamber 21 falling into the electric control chamber 411 through the air inlet 412. Among them, the side wall of the water shield 70 is provided with at least one air hole 721, so that the air outlet 424 is connected to the upper chamber 21 through the opening and the air hole 721 in sequence. The side wall of the water shield 70 is the side plate 72 of the water shield 70. The air hole 721 is provided on the side wall of the water shield 70 to reduce the probability of condensed water entering the air outlet 424 through the air hole 721, so that the water shield 70 has a waterproof effect. In this embodiment, the side wall of the water shield 70 is provided with a plurality of air holes 721, and the plurality of air holes 721 are arranged in sequence and spaced along the circumference of the water shield 70.

[0053] According to the embodiments of the present utility model, Figure 1 As shown, an air conditioner 200 is also proposed, which includes a shell assembly 100, a fan 201, a heat exchanger 202 and an electronic control device 203, wherein the fan 201 is installed at an exhaust port 2101 in the shell assembly 100, the heat exchanger 202 is arranged in an upper chamber 21 in the shell assembly 100; and the electronic control device 203 is arranged in an electronic control chamber 411 in the shell assembly 100.

[0054] According to the air conditioner 200 proposed by the utility model, an air inlet 412 and an air outlet 424 are arranged on the electric control box 40, and the electric control chamber 411 is connected with the upper chamber 21 through the air outlet 424, and the fan 201 is used to drive the air in the upper chamber 21 to flow to the outside of the upper chamber 21, so that a negative pressure is generated in the upper chamber 21, and under the suction effect of the negative pressure of the upper chamber 21, the external air flow enters the electric control chamber 411 through the air inlet 412, and fully exchanges heat with the electric control device 203 in the electric control chamber 411 during the process of flowing through the electric control chamber 411, and flows into the upper chamber 21 through the electric control chamber 411 and the air outlet 424, thereby effectively improving the heat dissipation efficiency of the electric control device 203.

[0055] Furthermore, when the air conditioner 200 is in the process of providing heat, the heat exchanger 202 arranged in the upper chamber 21 serves as an evaporator. After the external airflow flows through the electric control chamber 411 to dissipate the heat for the electric control device 203 in the electric control chamber 411, the heat dissipated by the electric control device 203 can be replaced into the upper chamber 21, thereby improving the heat absorption capacity of the heat exchanger 202 in the upper chamber 21 and making full use of the heat energy generated by the electric control device 203.
