[0002] When the heat pump system is in use, the heat pump unit (including compressor, evaporator, condenser and expansion valve) and the electronic control system (including electronic devices) are encapsulated in the box for protection. The conventional box is formed by setting a panel seal on the frame, wherein the front panel and the maintenance panel arranged on the front face are installed side by side, and the main components of the heat pump, such as the compressor, water pump, valve group, etc., are arranged at the corresponding position of the maintenance panel for subsequent maintenance.

[0003] In order to ensure the neatness and consistency of the front face, the front panel and maintenance plate of the existing heat pump box generally adopt a through-top design, that is, the top cover cannot be seen from the front. After the top cover is installed, the edges of the top cover abut against the inner sides of the front panel and the maintenance plate, resulting in an installation gap between the edge of the top cover and the inner sides of the front panel and the maintenance plate. Since the installation gap is located at the top of the box, when there is rain on the top, there is a risk of rainwater leaking into the box along the installation gap, and the connection point between the compressor, water pump, valve group and other components and the heat pump electric control box is also located in the inner area of ​​the box corresponding to the maintenance plate. If the waterproof measures for the installation gap are not in place, it may cause the connection point between the main components of the heat pump and the electric control box to short-circuit due to moisture. Therefore, there is still room for improvement. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0036] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] The utility model provides a heat pump housing. Figure 1 and Figure 2As shown, the length, width and height directions of the heat pump housing are respectively set as X direction, Y direction and Z direction. The end face of the heat pump housing includes a front panel 1 and a maintenance panel 7 arranged side by side along the length direction (X direction), which are respectively arranged and installed separately corresponding to the fan side and the electrical side. The maintenance panel 7 is arranged separately to facilitate the inspection and maintenance operation of the electrical side. The heat pump housing corresponding to the maintenance panel 7 is provided with the wiring of the heat pump main components and the electric control box 100. After installation, the front panel 1 and the maintenance panel 7 form an installation gap 3 along the X direction with the top plate 2, as shown in FIG. Figure 7 Along the width direction (Y direction) of the heat pump housing, the installation gap 3 and the electric control box 100 are staggered, that is, arranged in sequence, so as to avoid water leakage causing short circuit leakage of the electric control box 100. If water leakage occurs at the installation gap 3, especially if water leakage occurs at the installation gap 3 between the maintenance plate 7 and the top plate 2, it will cause the risk of short circuit leakage of the wiring of the electric control box 100. Therefore, the heat pump housing has high requirements for waterproofing and needs reliable waterproof protection. The existing top waterproof structure of the heat pump housing has low strength and low waterproof reliability, and needs to be improved.

[0038] like Figure 3-Figure 8 As shown, the heat pump housing includes a front panel 1, a maintenance plate 7 and a top plate 2, and a mounting gap 3 is formed between the front panel 1, the maintenance plate 7 and the top plate 2; a water retaining groove 4 is provided in the heat pump housing, the water retaining groove 4 is arranged below the mounting gap 3 and extends along the length direction of the mounting gap 3, a drainage groove 5 is provided at the bottom of the water retaining groove 4, and a drainage hole 51 is provided at the bottom of the drainage groove 5, and the drainage hole 51 is staggered with the maintenance plate 7 along the length direction (X direction) of the heat pump housing.

[0039] The heat pump box of the utility model is as follows Figure 3-Figure 8 The water retaining groove 4 is arranged below the installation gap 3, and both are arranged along the X direction. The length of the water retaining groove 4 is not less than the length of the installation gap 3. A drainage groove 5 is arranged at the bottom of the water retaining groove 4. Under the condition that the structure allows, a drainage groove 5 with a larger length may be arranged along the length direction of the water retaining groove 4 as much as possible, such as Figure 5The drainage groove 5 is arranged behind the front panel 1, and a drainage hole 51 is arranged at the bottom of the drainage groove 5. The drainage hole 51 and the maintenance plate 7 are offset along the length direction (X direction) of the heat pump case, and are arranged in sequence, that is, the drainage hole 51 and the front panel 1 are arranged correspondingly in the width direction (Y direction). When water leaks from the installation gap 3 and drips downward, the water retaining groove 4 will receive the leaked water, and since the drainage groove 5 is provided at the bottom of the water retaining groove 4, the leaked water can be further collected in the drainage groove 5, and then discharged through the drainage hole 51 in the drainage groove 5. Since the drainage hole 51 and the maintenance plate 7 are offset along the length direction of the heat pump case, the water body will not fall into the internal area of ​​the case corresponding to the maintenance plate 7, thereby preventing the leaked water from falling on the wiring of the main components of the heat pump and the electrical control box 100, thereby ensuring the stability of the heat pump operation. At the same time, the drainage groove 5 further increases the depth of the water retaining groove 4, thereby avoiding the risk of water overflowing from the top due to insufficient depth of the water retaining groove 4, and improving the waterproof reliability; the drainage groove 5 is arranged at the bottom of the water retaining groove 4 along the length direction, which has the effect of reinforcing and strengthening the water retaining groove 4, thereby improving the structural strength of the water retaining groove 4 and helping to increase the service life.

[0040] In one of the embodiments, the bottom of the water retaining groove 4 is inclined downward from the edge toward the drainage groove 5, which is more conducive to the water in the water retaining groove 4 flowing into the drainage groove 5 and only drained by the drainage groove 5. The drainage efficiency is high and the reliability is high, and the water in the water retaining groove 4 can be prevented from overflowing.

[0041] In one embodiment, a plurality of drainage holes 51 are provided, and the plurality of drainage holes 51 are spaced apart along the length direction of the drainage groove 5 .

[0042] like Figure 5 As shown, in this embodiment, six drainage holes 51 are arranged at the bottom of the drainage groove 5, and the drainage holes 51 are arranged at intervals. The drainage holes 51 are connected to the cavity on the fan side, so that the leakage water received by the water retaining groove 4 converges to the drainage groove 5 and then drains from the drainage holes 51. The interval arrangement of multiple drainage holes 51 can reduce the accumulation of water in the drainage groove 5, which is conducive to rapid emptying.

[0043] In one embodiment, the drainage groove 5 is formed by the bottom of the water retaining groove 4 being concave downward, and has good formability and sealing performance.

[0044] In one embodiment, the front edge of the top plate 2 has a first lower flange 21, the outer side of the first lower flange 21 abuts against the front panel 1 and the maintenance plate 7 to form an installation gap 3, and the inner side of the first lower flange 21 abuts against the inner plate 41 of the water retaining groove 4 facing the top plate 2.

[0045] like Figure 7 and Figure 8, the top plate 2 is folded downward toward one side of the installation gap 3 to form a first lower flange 21, and the top edges of the front panel 1 and the maintenance plate 7 are also folded twice to form a second lower flange 12. When the top plate 2 is installed, the first lower flange 21 and the second lower flange 12 abut to form the installation gap 3, and the installation gap 3 is staggered from the electric control box 100 along the Y direction. In this embodiment, the water retaining groove 4 is arranged below the installation gap 3, and the water retaining groove 4 is formed by bending a thin plate member. The two sides of the water retaining groove 4 are respectively an inner plate 41 and an outer plate 45, and the inner side surfaces of the inner plate 41 and the outer plate 45 are the groove walls of the water retaining groove 4, and the water retaining groove 4 is installed and fixed by the inner plate 41 and the outer plate 45. In order to achieve a better installation and positioning effect, the inner side surface of the first lower flange 21 is arranged to abut against the inner side surface of the inner plate 41, which has the effect of enhancing the strength of the first lower flange 21. The inner plate 41 can provide a force for the first lower flange 21 to abut against the second lower flange 12, thereby reducing leakage at the installation gap 3, enhancing the installation strength of the top plate 2, and facilitating the limiting of the top plate 2 during installation.

[0046] In one embodiment, the end of the first lower flange 21 of the top plate 2 abuts against the bottom of the water retaining groove 4 .

[0047] like Figure 8 As shown, when the end of the first lower flange 21 abuts against the bottom of the water retaining groove 4, it can prevent the leaking water in the water retaining groove 4 from overflowing upward through the inner plate 41 or the outer plate 45 of the water retaining groove 4, further increasing the waterproof effect of the wiring part of the electric control box 100. The end of the first lower flange 21 abuts against the bottom of the water retaining groove 4, which can provide a limit when installing the top plate 2, thereby improving the installation efficiency and installation accuracy.

[0048] In one embodiment, the top end of the inner side plate 41 of the water retaining groove 4 facing the top plate 2 has an upper flange 42 folded away from the water retaining groove 4 , and the upper flange 42 is connected to the electric control box 100 .

[0049] like Figure 5-Figure 8 The top of the inner plate 41 of the water retaining groove 4 is folded outward by 90° to form an upper flange 42, and the upper flange 42 is provided with a mounting hole. The upper flange 42 is covered on the upper surface of the electric control box mounting plate 101, and the electric control box mounting plate 101 is used to install the electric control box 100. The upper flange 42 is connected to the electric control box mounting plate 101 through a connecting piece to achieve the installation and fixation of the water retaining groove 4, and at the same time make the installation of the electric control box 100 more stable and firm. The upper flange 42 is formed by folding the top of the inner plate 41 of the water retaining groove 4, so it is an integrated structure with the water retaining groove 4, which has the effect of enhancing the overall structural strength of the water retaining groove 4.

[0050] In one embodiment, the outer side surface of the outer side plate 45 of the water retaining groove 4 abuts against the inner side surfaces of the front panel 1 and the maintenance plate 7 .

[0051] like Figure 3 As shown, the front end face of the heat pump housing is provided with a support column 6 for connecting and fixing the front panel 1 and the maintenance plate 7, wherein the longitudinal edge (Z direction) of the front panel 1 is provided with a connection portion 11 for connecting the support column 6, and similarly, the longitudinal edge of the maintenance plate 7 is also provided with a connection portion 11 for connecting the support column 6 (not shown in the figure), and when the water retaining groove 4 is installed, the outer side surface of the outer plate 45 of the water retaining groove 4 abuts against the inner side surface of the support column 6, and in the absence of the support column 6, the outer side surface of the outer plate 45 directly abuts against the connection portion 11 of the front panel 1 or the maintenance plate 7 to achieve the installation limit function. It can be understood that the groove width of the water retaining groove 4 is equal to the spacing between the support column 6 and the electric control box mounting plate 101, so as to facilitate the clamping between the two to achieve the water retaining function and stable installation.

[0052] In one embodiment, a water retaining plate 43 is provided at a first end of the water retaining groove 4 facing the maintenance plate 7 , and a drainage notch 44 is provided at a second end of the water retaining groove 4 facing the front panel 1 .

[0053] like Figure 4 and Figure 6 As shown, the end facing the maintenance plate 7 is the first end, and the first end is provided with a water retaining plate 43. The outer plate 45 is bent toward the end of the water retaining groove 4 and abuts against the inner plate 41 to form the water retaining plate 43. The water retaining plate 43 is welded and sealed with the inner plate 41. The water retaining plate 43 is used to block the water in the water retaining groove 4 to prevent leakage from the first end. The end facing the front panel 1 is the second end, and the second end is a drainage gap 44. The second end of the water retaining groove 4 is an open structure, and the end of the outer plate 45 is shortened by a section, so as to form a drainage gap 44 at the second end of the water retaining groove 4, which is conducive to the leakage water in the water retaining groove 4 to converge downward from the drainage gap 44 toward the end of one side of the front panel 1, and prevent water from accumulating in the water retaining groove 4. It can be understood that during installation, the horizontal height of the groove bottom of the first end can be set higher than the horizontal height of the groove bottom of the second end, which is conducive to the water in the water retaining groove 4 flowing from the first end to the second end, so that the water is collected and discharged at the end away from the maintenance plate 7, and the electrical waterproof reliability and safety are improved.

[0054] In one of the embodiments, a water receiving tray is provided in the heat pump housing, and the water receiving tray is arranged below the drainage groove 5 .

[0055] Usually, a water collecting pan is arranged at the bottom of the heat pump housing. The water collecting pan is arranged corresponding to the drainage groove 5 along the Z direction and is located at the inner bottom of the front panel 1. It can uniformly collect and process the water passing through the drainage hole 51 and the water passing through the drainage gap 44, so that the excess water can be discharged from the heat pump housing in time to avoid water accumulation.

[0056] An embodiment of the utility model further provides a heat pump system, comprising the heat pump box provided in the above embodiment.

[0057] The heat pump system of the present invention has a water retaining groove 4 arranged in the heat pump housing, a drainage groove 5 arranged at the bottom of the water retaining groove 4, a drainage hole 51 arranged at the bottom of the drainage groove 5, and the drainage hole 51 is staggered with the maintenance plate 7 along the length direction of the heat pump housing, which effectively avoids leaked water from falling into the cavity behind the maintenance plate 7, improves the waterproof reliability of the heat pump main components and the wiring of the electric control box in the heat pump housing, and the drainage groove 5 can avoid the risk of overflow and leakage at the top due to insufficient depth of the water retaining groove 4, thereby improving the waterproof reliability and the structural strength of the water retaining groove 4, which is conducive to improving the service life of the heat pump system.

[0058] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The specific contents of the above specific implementations only express several implementations of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
