[0025] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0026] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0027] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0028] In the pool dehumidification heat pump unit, a water collecting pan needs to be set at the bottom of the chassis of the heat exchanger section to collect condensed water and then discharge it centrally. The bottom plate of the existing water collecting pan is generally bent to set two or three drainage grooves. After the condensed water on the heat exchanger drips onto the water collecting pan, it will be collected in the drainage grooves and then discharged from the drainage holes set at both ends of the drainage grooves. The manufacturing process of the existing water collecting pan is generally sheet metal + welding process. Because the drainage grooves are bent on the bottom plate, the existing water collecting pan must be welded by splicing multiple metal plates. Since the length of the weld after splicing is long, in actual use, there is usually a problem of water leakage in the water collecting pan due to local lax welding.

[0029] In order to overcome the above technical problems, Figure 1-2 As shown, this embodiment provides a dehumidifier chassis, including a chassis frame 1, a water receiving tray 2 and a heat exchanger bracket 3, wherein the water receiving tray 2 is installed on the chassis frame 1, and the water receiving tray 2 is integrally formed and used to collect condensed water; the heat exchanger bracket 3 is installed on the water receiving tray 2 and used to support the heat exchanger 4.

[0030] The water receiving tray 2 is made in one piece, and can be made of a complete plate body by sheet metal + welding process, or can be cast in one piece, or can be made by milling a water receiving groove in the middle of a complete thick plate. Preferably, it is made of a complete plate body by sheet metal + welding process, which is simple to make, requires less consumables, and has low cost.

[0031] The dehumidifier chassis of this embodiment can be used to collect condensed water dripping from the heat exchanger 4 in the dehumidifier during operation. The dehumidifier chassis of this solution includes a chassis frame 1, a water receiving tray 2 and a heat exchanger bracket 3. The chassis frame 1 serves as the main support body at the bottom and can provide stable support for the water receiving tray 2. The water receiving tray 2 is directly made in one piece, and there is no splicing weld on the bottom plate of the water receiving tray 2, so the problem of water leakage due to weld defects can be effectively avoided. This solution also provides a heat exchanger bracket 3 on the water receiving tray 2 to support and fix the heat exchanger 4, thereby improving the reliability of the installation of the heat exchanger 4. Moreover, based on the support of the heat exchanger bracket 3, the installation height of the heat exchanger 4 can also be raised to prevent the bottom of the heat exchanger 4 from being immersed in water for a long time.

[0032] In one embodiment, referring to Figure 4 The water receiving tray 2 includes a tray bottom plate 21 and a tray surrounding wall plate 22. The tray bottom plate 21 is provided with a plurality of extension parts on its periphery. The tray surrounding wall plate 22 includes a plurality of side wall plates 221 formed by bending the extension parts. The adjacent connecting edges of each side wall plate 221 are fixedly connected by full welding.

[0033] Specifically, the water collecting pan 2 of the present embodiment is made of sheet metal + welding process. During the production, the excess scraps are cut off from the four corners of a complete metal plate, and the four sides are reserved for bending to form the material of the side wall plate 221. The middle is the pan bottom plate 21, and the material around the pan bottom plate 21 is the extension part. Then, the extension part around the pan bottom plate 21 is bent upward to form four side wall plates 221 connected end to end, and finally the joints of the side wall plates 221 are welded and sealed.

[0034] The bottom plate 21 of the water receiving tray 2 of the present solution is a complete plate, so there is no leakage problem. The connection between the bottom plate 21 and the side wall plate 221 is also made of one piece, so there is no leakage problem. The side wall plates 221 on all sides are welded together, the weld length is short, and the risk of leakage is also small.

[0035] To facilitate drainage, a drainage interface for connecting a drainage pipe is pre-opened on the side wall plate 221 of the water receiving tray 2.

[0036] In one embodiment, a side of the pan surrounding wall plate 22 away from the pan bottom plate 21 is connected to a folded edge 23 extending toward the center of the water receiving pan 2 .

[0037] The top side of the pan surrounding wall plate 22 is bent inward to form a folded edge 23, which can make the top edge of the pan surrounding wall plate 22 blunt and avoid cutting hands during assembly; and the folded edge 23 can provide a gripping point for hands, and during assembly, fingers can be buckled on the inner side of the folded edge 23 to move the water receiving pan 2, thereby facilitating assembly operations.

[0038] In one embodiment, the heat exchanger bracket 3 is fixed to the water receiving tray 2 by welding.

[0039] The heat exchanger bracket 3 is fixed to the water receiving pan 2 by welding, which can avoid water leakage caused by opening holes in the water receiving pan 2, and can reliably fix the heat exchanger bracket 3 to the water receiving pan 2 to ensure the stability of the heat exchanger 4 installed thereon.

[0040] In one embodiment, referring to Figure 1-3 The heat exchanger bracket 3 includes a plurality of support beams 31 arranged in parallel, and the support beams 31 are arranged perpendicular to the heat exchanger 4 .

[0041] Specifically, the heat exchanger 4 is generally a fin heat exchanger, a surface cooler, etc. The heat exchanger 4 is a flat rectangular parallelepiped, and the two surfaces with the largest area of ​​the rectangular parallelepiped are one windward side and the other windward side. The support beam 31 of this solution is vertically arranged with the heat exchanger 4, which means that the length direction of the support beam 31 is vertical with the windward side and the windward side of the heat exchanger 4. In a dehumidifier, multiple heat exchangers 4 are generally used side by side. The support beam 31 of this solution is vertically arranged with the heat exchanger 4, so that multiple heat exchangers 4 can be supported at the same time, providing a stable support foundation for multiple heat exchangers 4.

[0042] In one embodiment, the heat exchanger bracket 3 also includes a windbreak 32, which is arranged between each of the support beams 31, and the bottom side of the windbreak 32 contacts the surface of the water receiving tray 2, and the top side is used to contact the bottom side of the heat exchanger 4 to isolate the gap between the heat exchanger 4 and the water receiving tray 2.

[0043] Specifically, the support beam 31 in the heat exchanger bracket 3 serves as the main support body to support the heat exchanger 4, which can prop up the heat exchanger 4 to prevent the bottom of the heat exchanger 4 from being immersed in water. However, since there will be a certain gap between the bottom of the heat exchanger 4 and the water surface on the water receiving tray 2 during use, a small amount of wind will pass through the gap during operation. This part of the wind cannot pass through the thermal glue exchange with the heat exchanger 4 and is directly discharged, that is, there is a problem of air leakage. For this reason, the present solution also provides windproof strips 32 between the support beams 31. The windproof strips 32 are specifically provided according to the installation position of the heat exchanger 4 at a later stage, as long as the windproof strips 32 can contact the bottom side of the heat exchanger 4 after installation to achieve the windproof effect. Therefore, the windproof strips 32 provided in the heat exchanger bracket 3 of the present solution can effectively solve the problem of air leakage at the bottom of the heat exchanger 4.

[0044] Preferably, the wind shielding strip 32 is a C-shaped profile, which has a sufficiently large contact area with the heat exchanger 4 and the water receiving tray 2, and has better installation reliability. It also has the advantages of less consumables and light weight.

[0045] In one embodiment, referring to Figure 5-6 The support beam 31 includes a beam top plate 311 and beam side plates 312 respectively connected to both sides of the beam top plate 311 and extending toward the water receiving pan 2 relative to the beam top plate 311. The beam top plate 311 is provided with a positioning hole 3111 for locking the heat exchanger 4, and the beam side plates 312 are welded and fixed to the water receiving pan 2.

[0046] Specifically, the support beam 31 of this form is a hollow structure, which can provide a sufficiently large support area for the heat exchanger 4, can ensure reliable connection with the heat exchanger 4, and has the advantage of less consumables. A positioning hole 3111 is opened on the beam top plate 311, and the heat exchanger 4 can be locked to the beam top plate 311 by a bolt and nut assembly, that is, this structure can facilitate the assembly and fixation of the heat exchanger 4, and the installed heat exchanger 4 also has the advantage of convenient disassembly.

[0047] In one embodiment, a water hole 3121 is provided on one side of the beam side plate 312 connected to the water receiving tray 2 .

[0048] Specifically, water holes 3121 are provided on the bottom sides of the beam side plates 312 , so that the condensed water between the beam side plates 312 can flow to each other, so that the accumulated water on the entire water receiving tray 2 can be quickly discharged.

[0049] In one embodiment, one side of the beam side plate 312 connected to the water receiving tray 2 is bent to form a supporting edge 3122 parallel to the water receiving tray 2 .

[0050] Specifically, the support edges 3122 are formed by bending the bottom side of the beam side plate 312, which can effectively increase the connection area between the support beam 31 and the water receiving tray 2 and improve the reliability of the support beam 31 after welding. The support edges 3122 on the bottom sides of the two beam side plates 312 can be bent toward each other or away from each other.

[0051] In one embodiment, the chassis frame 1 includes an outer frame 11 and a supporting base frame 12 embedded in the outer frame body 11, the upper surface of the supporting base frame 12 is lower than the upper surface of the outer frame body 11, the supporting base frame 12 and the outer frame body 11 are surrounded to form an installation groove, and the water receiving tray 2 is installed in the installation groove.

[0052] Specifically, a support frame 12 is provided in the outer frame 11 to support the bottom of the water receiving tray 2, and support can be provided from the middle of the water receiving tray 2, so that the weight on the water receiving tray 2 can fall on the support frame 12, thereby preventing the water receiving tray 2 from being deformed under load. The water receiving tray 2 is embedded in the chassis frame 1, and the outer frame 11 can cover the water receiving tray 2 from all sides, which can further improve the stability of the installation of the water receiving tray 2.

[0053] Preferably, the supporting base frame 12 includes a plurality of bottom beams corresponding to the setting positions of the supporting beams 31, that is, under the water receiving tray 2, a bottom beam is correspondingly arranged under each supporting beam 31 to provide support, so that the downward gravity of the supporting beam 31 can directly act on the bottom beam, thereby reducing the load-bearing capacity of the water receiving tray 2.
