Description

Technical Field

[0001] This utility model relates to the field of heat pump unit technology, and in particular to a water receiving tray and a low-temperature heating module unit. Background Technology

[0002] With the continued advancement of the "coal-to-electricity" conversion, many areas in northern China have widely adopted low-temperature heating modular units as a winter heating solution. During operation in cold regions, the ice-melting capacity of the unit's drip tray becomes a key factor in ensuring the system's stable and efficient operation. If ice in the drip tray is not melted in time or drainage is obstructed, ice can easily accumulate under the evaporator fins, not only reducing heat exchange efficiency but also potentially causing the heat exchange copper pipes to freeze and crack, leading to unit malfunction and shutdown. Therefore, low-temperature heating modular units typically incorporate electric heating elements in the drip tray area to achieve anti-freezing and de-icing functions.

[0003] However, the traditional electric heating belt structure consists of the electric heating belt body and the terminal block. During installation, additional fixing brackets and screw fastening methods are required. This not only makes assembly complicated and inefficient, but also makes the screws prone to oxidation and corrosion during long-term operation, resulting in rust seepage and affecting the overall appearance quality of the unit.

[0004] In view of this, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a water receiving pan and a low-temperature heating module unit that is simple and efficient to assemble without affecting the overall appearance quality of the unit. This solves the problems of complex assembly, low efficiency, and the fact that screws are prone to oxidation and corrosion during long-term operation, resulting in rust seepage and affecting the overall appearance quality of the unit.

[0012] Optionally, the elastic buckle includes two latching portions that extend along the insertion direction of the heating assembly and are spaced apart from each other, forming a slot between the two latching portions.

[0013] Optionally, each of the latching parts is provided with a guide ramp, and the thickness of the latching part gradually increases as the distance from the slot decreases, so as to guide the elastic buckle into the slot along the guide ramp.

[0014] Optionally, the hook includes an extension and a snap-in portion disposed at one end of the extension, the snap-in portion being perpendicular to the extension and configured to snap into the slot.

[0015] Optionally, the sheath is elastic, and the side of the sheath facing the disc body is a heat-bonding surface, which abuts against the bottom of the disc body.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0030] Please see Figures 1-3 In a first aspect, this utility model provides a water receiving tray 100, comprising: a tray body 10 and a heating component 20. The tray body 10 is provided with a guide groove, and one side of the guide groove is provided with an opening. The heating component 20 includes a sheath 22 and at least one electric heating band 21 disposed on the sheath 22. The heating component 20 is inserted into the guide groove so that the electric heating band 21 supplies heat to the tray body 10.

[0031] The water receiving tray 100 of this utility model has a slot on the tray body 10. The heating component 20 is inserted into or removed from the slot through the opening at one end of the slot to fix the heating component 20 on the tray. In other words, the user can assemble or detach the heating component 20 from the tray body 10 by simply inserting or removing it. The assembly is simple and efficient, and no fasteners are involved in the assembly, so there is no risk of fastener rust affecting the overall appearance quality of the unit.

[0032] The sheath 22 provides mounting support for the electric heating band 21. During the insertion of the heating assembly 20 into the slot, the sheath 22 drives the electric heating band 21 to move synchronously. The electric heating band 21 is a slender strip structure with heating function, used to provide heat energy to the pan 10 to solve the problems of untimely ice melting and poor drainage in the water receiving pan 100, which easily leads to ice accumulation under the evaporator fins.

[0033] In one specific embodiment, the disc body 10 is provided with a hook 11, and the protective sleeve 22 is provided with an elastic buckle 23 adapted to the hook 11 on the side opposite to the disc body 10.

[0034] During the insertion of the heating component 20 into the slot, the sheath 22 drives the elastic buckle 23 to move synchronously until the elastic buckle 23 on the sheath 22 engages with the hook 11, so as to solve the problem that the heating component 20 still moves relative to the plate body 10 after being inserted into the slide groove, and further improves the stability of the installation of the heating component 20.

[0035] Unlike traditional hook and latch positioning, the hook 11 in this embodiment is elastic, and the elastic latch 23 adapts to both the pre-insertion and post-insertion scenarios through its own elastic deformation. Specifically, when the electric heating band 21 assembly is pushed horizontally along the guide groove, the elastic latch 23 undergoes elastic deformation under the pressure of the guide groove. After entering the guide groove, it returns to its original shape under its own rebound force, locking into the guide groove to form a self-locking mechanism, preventing the elastic band from coming out vertically. At the same time, the latch 232 restricts the degree of freedom of the electric heating band 21 in the horizontal direction.

[0036] During installation, the operator only needs to align one end of the electric heating strip 21 assembly with the starting end of the guide groove and push it smoothly in a horizontal direction. The elastic buckles 23 will automatically engage with the guide grooves one by one until the entire electric heating strip 21 is fully installed, without the need for any tools or auxiliary fasteners. For disassembly, appropriate external force can be applied to compress and deform the elastic buckles 23, allowing them to slide out easily, facilitating maintenance and replacement and providing a good user experience.

[0037] In one specific embodiment, the elastic buckle 23 includes two latching portions 231, which extend along the insertion direction of the heating component 20 and are spaced apart from each other, forming a slot 232 between the two latching portions 231.

[0038] The lateral width of each elastic buckle 23 is slightly larger than the inlet width of the preset guide groove on the water receiving tray 100 body, so that the hook 11 can fall into the slot 232. After the hook 11 falls into the slot 232, the locking parts 231 on both sides abut against the hook 11 and limit the hook 11 to keep the heating component 20 and the tray 10 relatively stationary.

[0039] Furthermore, each of the latching parts 231 is provided with a guide ramp, and the thickness of the latching part 231 gradually increases as the distance from the latching groove 232 decreases, so as to guide the elastic buckle 23 into the latching groove 232 along the guide ramp.

[0040] The snap-fit ​​portion 231 can be triangular. A guide ramp is provided on the side of the snap-fit ​​portion 231 facing away from the sheath 22. During the sliding of the heating assembly 20 within the slot 232 of the disc body 10, the hook 11 enters the slot 232 along the guide ramp of one of its snap-fit ​​portions 231, thus making the hook 11 engage with the elastic buckle 23 more smoothly and providing a better user experience.

[0041] Optionally, the hook 11 includes an extension 111 and a snap-in portion 112 provided at one end of the extension 111. The snap-in portion 112 is perpendicular to the extension 111 and is configured to snap into the slot 232.

[0042] The elastic latch 23 extends downward from the bottom wall of the disc body 10. Specifically, the extension 111 connects the disc body 10 and the latching portion 112. The length of the extension 111 is configured to be slightly longer than the thickness of the heating assembly 20 so that the latching portion 112 can be located below the heating assembly 20. Furthermore, the extension 111 is located on one side of the heating assembly 20 to avoid interference with its downward movement. The latching portion 112 is bent at 90° relative to the extension 111, and at least part of the latching portion 112 is located directly below the heating assembly 20. This specific structure of the latch 11 is configured to achieve a mating connection between the latching portion 112 and the latching groove 232.

[0043] In one specific embodiment, the sheath 22 is elastic, and the side of the sheath 22 facing the disc body 10 is a heat-bonding surface, which abuts against the bottom of the disc body 10.

[0044] The sheath 22 is elastic, allowing it to bend to a certain extent, further improving the assembly efficiency of the heating component 20. Preferably, the sheath 22 can be made of silicone rubber. Silicone rubber not only possesses elasticity, providing elastic support for the elastic buckle 23 to reduce its own deformation, but also exhibits excellent heat resistance, with relatively stable physical properties at high temperatures, making it suitable for applications involving the installation of the electric heating belt 21.

[0045] When the electric heating band 21 is energized, it generates heat, which is transferred to the sheath 22 via thermal conduction, and then from the sheath 22 to the disc body 10. The heat-bonding surface is in close contact with the disc body 10 to eliminate gaps between them, thereby improving heat conduction efficiency.

[0046] In one specific embodiment, there are multiple elastic buckles 23, which are evenly distributed on the sheath 22; the hooks 11 are set in a one-to-one correspondence with the elastic buckles 23.

[0047] By setting multiple elastic buckles 23 and configuring hooks 11 that correspond one-to-one with the elastic buckles 23, the contact points between the disc body 10 and the heating component 20 can be increased, thereby reducing the local stress of the heating component 20 and improving the stability and service life of the engagement between the hooks 11 and the elastic buckles 23.

[0048] In this embodiment, the elastic buckles 23 are divided into two groups, and each group of elastic buckles 23 includes three elastic buckles 23 evenly distributed along the length of the sheath 22.

[0049] In one specific embodiment, the electric heating band 21 is enclosed within the sheath 22.

[0050] Understandably, the electric heating band 21 is integrated onto the sheath 22 and encapsulated within the sheath 22.

[0051] The sheath 22 and the electric heating band 21 are integrally formed, and no additional means are needed to fix them together, which further improves the assembly efficiency of the heating component 20.

[0052] Of course, the electric heating band 21 can also be integrated into the sheath 22 by using adhesive or fasteners to lock the sheath 22 toward the side of the disc body 10, without being limited by the specific embodiment.

[0053] In one specific embodiment, there are multiple electric heating bands 21, which are arranged parallel to each other and spaced apart along the width direction of the sheath 22.

[0054] Multiple electric heating strips 21 are integrated onto the sheath 22 to improve the heating efficiency of the water receiving tray 100. The sheath 22 is rectangular, with the width direction of the sheath 22 being the relatively narrower side. It is understood that there can be three, four, five, or six electric heating strips 21, which is not specifically limited to this embodiment.

[0055] The integrated design of more than 21 electric heating strips not only increases the heating power density per unit area, but also significantly improves installation efficiency and structural stability. Furthermore, the structure is compact and the layout is reasonable.

[0056] A second aspect of this utility model provides a low-temperature heating module unit, comprising: any of the above-mentioned water receiving pans 100.

[0057] Low-temperature heating modular units are a type of heat pump unit that are suitable for use in low-temperature environments (e.g., -25℃ to -30℃) and can still stably and efficiently absorb heat from the air to provide hot water at a sufficient temperature for indoor heating terminals such as underfloor heating and fan coil units.

[0058] In this embodiment of the low-temperature heating module unit, the water receiving tray 100 of any of the above embodiments is used. A slot is provided on the tray body 10, and the heating component 20 is inserted into or removed from the slot through an opening at one end of the slot to fix the heating component 20 to the tray. In other words, the user only needs to insert or remove the heating component 20 to assemble or detach it from the tray body 10. Assembly is simple and efficient, and no fasteners are involved in the assembly. There is no risk of fastener rust affecting the overall appearance of the unit. The low-temperature heating module unit has high assembly efficiency and a good user experience.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the protection scope of this invention.
