[0027] The specific embodiments of the present application have been shown in the above-described drawings, and will be described in more detail hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be described clearly and completely in the following by referring to the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.

[0029] The heat pump air conditioner of the related art comprises an outdoor unit and an electric control drive board arranged in the outdoor unit. The electric control drive board is responsible for controlling and driving various modules of the air conditioner to operate, for example, controlling the start, stop and operating speed of the compressor to adjust the efficiency of refrigeration or heating, etc. In order to cool the electric control drive board, a cold plate connected with the heat generating module of the electric control drive board is arranged in the outdoor unit. The refrigerant is delivered into the cold plate to indirectly cool the heat generating module of the electric control drive board.

[0030] However, after the heat generating module of the electric control driving board is cooled by the cold plate, condensate water is generated on the heat generating module. If the condensate water accumulates between the electric control driving board and the cold plate, the electric control driving board may be corroded by the condensate water, thereby causing the electronic components on the electric control driving board to be damaged.

[0031] To solve the above technical problems, the present application provides a condensate water drainage structure and a heat pump equipment. When condensate water is generated on the electric control driving board, part of the condensate water can flow into the recessed portion along the second drainage gap, and part of the condensate water can fall onto the cold plate. The condensate water on the cold plate can flow onto the bottom wall of the recessed portion along the first drainage gap between the cold plate and the inner wall of the recessed portion. Because the drainage hole on the bottom wall of the recessed portion is arranged at the lowest point, the condensate water on the bottom wall of the recessed portion can flow to the position of the drainage hole due to gravity, thereby being drained along the drainage hole. This prevents the condensate water from accumulating between the electric control driving board and the cold plate, causing the electric control driving board to be damaged, and prevents the condensate water from accumulating on the cold plate, causing the cold plate to be damaged. The service life of the electric control driving board and the cold plate is indirectly prolonged.

[0032] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can exist independently or in combination. For the same or similar concepts or processes, some embodiments may not be described again. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0033] In combination with Figures 1 to 3 A condensate water drainage structure comprises:

[0034] A tray 100 is used to mount a heat dissipation component. The tray 100 is provided with a recessed portion 130. A drainage hole 131 is arranged on the bottom wall of the recessed portion 130.

[0035] A first mounting assembly 200 is arranged on the tray 100. The first mounting assembly 200 is used to mount a cold plate 800 of the heat dissipation component, so that a first drainage gap 210 is formed between the cold plate 800 and the inner wall of the recessed portion 130.

[0036] In this embodiment, the heat dissipation component is an electric control driving board 700 of a heat pump equipment. The tray 100 comprises a bottom plate 110 and a side plate 120 arranged along the circumferential edge of the bottom plate 110. The recessed portion 130 is arranged as a region recessed downwardly from the bottom plate 110 of the tray 100. The recessed portion 130 is arranged in a "U" shape. The open end of the "U" shaped recessed portion 130 is used to pass through the refrigerant pipeline of the cold plate 800. The width of the cold plate 800 is smaller than the width between the opposite sides of the recessed portion 130, so that the condensate water can pass through between the cold plate 800 and the side wall of the recessed portion 130.

[0037] In the present application, by adopting the setting of the recess 130, the electric control driving plate 700 is installed on the tray 100, the cold plate 800 is arranged on the first mounting assembly 200, part of the condensed water on the electric control driving plate 700 can flow into the recess 130, the condensed water on the cold plate 800 can flow along the cold plate 800 to the recess 130, so that the condensed water entering the recess 130 is discharged along the drain hole 131, preventing the condensed water from accumulating between the electric control driving plate 700 and the cold plate 800, thereby preventing the condensed water from causing damage to the electronic components on the electric control driving plate 700; by adopting the setting of the first mounting assembly 200 and the first drainage gap 210, because the cold plate 800 is arranged in the recess 130, the flow of condensed water towards the recess 130 is prevented from being blocked by the cold plate 800, and the condensed water accumulated on the bottom wall of the recess 130 is prevented from causing damage to the cold plate 800, thereby improving the discharge efficiency of the condensed water and indirectly prolonging the service life of the cold plate 800.

[0038] As shown in Figure 2 The first mounting assembly 200 includes at least one pad, which is arranged on the bottom wall of the recess 130.

[0039] In the present embodiment, four pads are provided, and the cross section of the pad is circular. The position of the pad on the bottom wall of the recess 130 can be adjusted as needed; a screw is arranged on the pad, which is threaded through and connected to the bottom wall of the recess 130. By adopting the setting of the screw, the height of the pad can be adjusted, thereby facilitating the adjustment of the level of the cold plate 800, and the abutting effect between the cold plate 800 and the electric control driving plate 700 can be adjusted through the screw, thereby indirectly improving the heat dissipation efficiency of the cold plate 800 on the electric control driving plate 700; in other embodiments, the number and shape of the pad can be adjusted as needed, for example, the pad can be set as a rectangle, or the pad can be connected to the bottom of the recess 130 by clamping, the pad can be a protrusion integrally arranged on the bottom plate 110, or a flange integrally arranged or detachably arranged on the side plate 120.

[0040] In the present application, by adopting the setting of multiple pads, the pad is connected to the bottom wall of the recess 130, and the cold plate 800 is connected to the pad, so that the first drainage gap 210 is formed between the cold plate 800 and the bottom wall of the recess 130. The setting of multiple pads is simple in structure and facilitates the production and manufacture of multiple pads; by detachably connecting the pad to the bottom wall of the recess 130, the pad can be easily disassembled and maintained, thereby facilitating the maintenance of the bottom wall of the recess 130 and the pad.

[0041] In combination with Figures 1 to 3The condensed water drainage structure further comprises a second mounting assembly 300 arranged in the tray 100, and the second mounting assembly 300 is used for mounting the heat dissipation component, so that a second drainage gap 310 is formed between the heat dissipation component and the bottom wall of the tray 100.

[0042] In the present application, by arranging the second mounting assembly 300 and the second drainage gap 310, the condensed water accumulated on the bottom wall of the tray 100 can be prevented from contacting the electric control driving board 700, so that the condensed water cannot damage the electric control driving board 700, and the electric control driving board 700 cannot block the condensed water from flowing towards the recess 130, thereby further improving the drainage efficiency of the condensed water in the tray 100 and prolonging the service life of the electric control driving board 700 and the cold plate 800.

[0043] In combination with Figures 1 to 3 The second mounting assembly 300 comprises at least one mounting column arranged in the tray 100.

[0044] In the present embodiment, eight mounting columns are arranged, four of which are arranged on the bottom plate 110 of the tray 100 and located on one side of the bottom plate 110, and the other four are arranged on the bottom plate 110 of the tray 100 and located on the other side of the bottom plate 110; the cross section of the mounting column is circular; the electric control driving board 700 is detachably connected to the mounting column by a bolt, the bolt is arranged on the electric control driving board 700, and the bolt is threadedly connected in the mounting column, so that the electric control driving board 700 is fixed on the mounting columns; in other embodiments, the mounting column can be a protrusion arranged integrally or detachably on the bottom plate 110; the mounting column can also be a step arranged integrally or detachably on the side plate 120.

[0045] In the present application, by arranging a plurality of mounting columns and connecting the electric control driving board 700 to the mounting columns, the electric control driving board 700 is separated from the bottom wall of the tray 100 to form the second drainage gap 310, and the mounting column has a simple structure and is easy to manufacture; by detachably connecting the electric control driving board 700 to the mounting column, the electric control driving board 700 is easy to disassemble and assemble, thereby facilitating the maintenance of the electric control driving board 700 and the bottom wall of the tray 100.

[0046] As shown in Figure 3 The bottom wall of the recess 130 is conical or inclined, and the drainage hole 131 is arranged at the lowest point of the bottom wall of the recess 130.

[0047] In the present embodiment, the bottom wall of the recess 130 is conical.

[0048] In other embodiments, the recess 130 can also be set as a pyramid shape, and the drain hole 131 is set at the lowest point of the pyramid-shaped recess 130, so that the condensed water can also flow into the drain hole 131 due to gravity. The bottom wall of the recess 130 can be arc-shaped, and the drain hole 131 is set at the lowest point of the recess 130 notch, so that the condensed water can also flow into the drain hole 131 due to gravity.

[0049] In the present application, by setting the bottom wall of the recess 130 as a taper, and setting the drain hole 131 at the lowest point of the bottom wall of the recess 130, the condensed water flowing onto the bottom wall of the recess 130 can automatically move towards the drain hole 131 due to gravity, thereby improving the discharge efficiency of the condensed water on the bottom wall of the recess 130, preventing the condensed water from accumulating on the bottom wall of the recess 130, causing volatilization to affect the electric control driving board 700 and the cold plate 800.

[0050] In combination with Figure 4 and Figure 5 , the condensed water drainage structure further comprises a partition plate 400 and a connecting assembly 500, the partition plate 400 has a recess 410 for accommodating the recess 130, and the connecting assembly 500 is used to detachably connect the partition plate 400 to the tray 100.

[0051] In the present application, the partition plate 400 is provided and detachably connected to the tray 100 through the connecting assembly 500, so that the partition plate 400 can support the tray 100, thereby indirectly improving the strength of the tray 100; by adopting the recess 410, when the recess 130 is moved into the recess 410, one side of the partition plate 400 can abut against the tray 100 and drive the recess 410 to abut against the recess 130, thereby increasing the contact area between the partition plate 400 and the tray 100, thereby further improving the support strength of the partition plate 400 to the tray 100; by adopting the connecting assembly 500, the tray 100 is convenient to disassemble and maintain.

[0052] In combination with Figure 4 and Figure 4 Figure 5 The connecting assembly 500 comprises a flange 510 and a connecting bolt, the flange 510 is arranged at the edge of the partition plate 400 close to the tray 100, the flange 510 abuts against the tray 100, and the flange 510 is detachably connected to the tray 100 through the connecting bolt.

[0053] In the present embodiment, the connecting bolt is arranged on the flange 510, and the shank of the connecting bolt is used to be screwed on the bottom wall of the tray 100.

[0054] In the application, the contact area between the partition plate 400 and the tray 100 is further increased by adopting the setting of the flange 510, the support strength of the partition plate 400 to the tray 100 is improved, and thus the fixing strength of the partition plate 400 fixed on the tray 100 is improved; the flange 510 and the tray 100 are disassembled in the mode of the connecting bolt, the disassembling mode is convenient and simple, the convenience of the installer in disassembling is improved, and the fixing strength between the flange 510 and the tray 100 is improved by adopting the fixing mode of the connecting bolt.

[0055] In combination Figure 4 and Figure 5 , the condensed water drainage structure further comprises a positioning assembly 600 arranged on the outer wall of the recess 130, and the positioning assembly 600 is used for positioning the position of the partition plate 400 on the recess 130.

[0056] In the application, the position of the partition plate 400 on the recess 130 can be positioned by adopting the setting of the positioning assembly 600, so as to facilitate the installation of the partition plate 400 and the tray 100 by the installer, and prevent the installation position between the partition plate 400 and the tray 100 from deviating.

[0057] In combination Figure 4 and Figure 5 , the positioning assembly 600 comprises two vertical ribs 610, and the two vertical ribs 610 are arranged on the outer wall of the recess 130 and have a positioning space for the edge of the partition plate 400 to move in between the two vertical ribs 610.

[0058] In the embodiment, the vertical rib 610 is arranged in a "U" shape, and the vertical rib 610 in the "U" shape is arranged along the circumference of the outer wall of the recess 130.

[0059] In the application, when the partition plate 400 is moved into between the two vertical ribs 610, the two vertical ribs 610 can position the position of the partition plate 400 on the outer wall of the recess 130, and the partition plate 400 and the tray 100 are fixed by the cooperation of the two vertical ribs 610, the flange 510 and the connecting bolt. Since the vertical rib 610 can prevent the partition plate 400 from moving in a direction perpendicular to the vertical rib 610, the number of connecting bolts used is reduced, so that the installer can fix the partition plate 400 and the tray 100 by using fewer connecting bolts, thereby improving the fixing efficiency between the partition plate 400 and the tray 100.

[0060] The application also provides a heat pump equipment comprising an outdoor unit and the condensed water drainage structure of any one of the above embodiments arranged on the outdoor unit.

[0061] In the application, the specific structure of the condensed water drainage structure has been described in detail in the above embodiments, and will not be described again.

[0062] In this embodiment, the heat pump device is configured as a heat pump air conditioner. In other embodiments, the heat pump device may also be configured as a heat pump water heater or other heat pump devices.

[0063] The heat pump device provided in this application embodiment, by setting a condensate drainage structure, allows some condensate to flow along the second drainage gap 310 into the recess 130 when condensate is generated on the electronic control drive board 700, and some condensate to fall onto the cold plate 800. The condensate on the cold plate 800 can flow along the first drainage gap 210 between the cold plate 800 and the inner wall of the recess 130 to the bottom wall of the recess 130. Since the drainage hole 131 on the bottom wall of the recess 130 is set at the lowest point, the condensate on the bottom wall of the recess 130 can flow to the location of the drainage hole 131 due to gravity, and then be discharged along the drainage hole 131. This prevents condensate from accumulating between the electronic control drive board 700 and the cold plate 800, which would damage the electronic control drive board 700, and also prevents condensate from accumulating on the cold plate 800, which would damage the cold plate 800, thus indirectly extending the service life of the electronic control drive board 700 and the cold plate 800.
