Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a refrigeration device and a water receiving tray assembly for the refrigeration device. Background Technology

[0002] Refrigeration equipment such as refrigerators, refrigerated display cases, and refrigerated wine cabinets are widely used in people's daily lives. They typically include a cabinet with refrigeration space, a compressor, a condenser, and an evaporator. The condenser, evaporator, and compressor are each located inside the cabinet and are connected by an evaporation pipe. The refrigerant circulates within the evaporation pipe to circulate among the condenser, evaporator, and compressor to form a refrigeration system, which provides cooling to the refrigerated space.

[0003] When the evaporator transfers cooling energy to the refrigerator's interior, moisture in the air near the evaporator condenses on it, forming frost. This frost reduces the evaporator's efficiency, so most refrigeration systems have a defrosting function to remove the frost. This is achieved by installing a drip tray inside the refrigerator to collect the defrost water and then evaporate it, eliminating the need to drain the defrost water outside the refrigerator.

[0004] The relevant technology involves clamping the evaporator tube into the drip tray to fix the evaporator tube to the drip tray. This technical solution has the following shortcomings: First, when applying force to squeeze the evaporator tube into the clamp, it is easy to damage the evaporator tube and reduce its service life. Second, when the vibration generated by the compressor during operation is transmitted to the evaporator tube, it causes wear between the evaporator tube and the clamp. Long-term vibration and wear may lead to damage to the evaporator tube, resulting in refrigerant leakage and failure to cool, which is unreliable. Utility Model Content

[0005] This utility model proposes a refrigeration device and a water tray assembly for the refrigeration device, aiming to at least solve the technical problem in the prior art where the unreasonable installation structure of the evaporator and water tray leads to easy damage and affects the reliability of operation.

[0006] This utility model proposes a water receiving tray assembly for refrigeration equipment. The water receiving tray assembly includes a water receiving tray and an evaporation tube. The water receiving tray includes a tray body and a side plate surrounding the tray body. The tray body and the side plate surround each other to form an upward-facing water receiving cavity, in which the evaporation tube is partially accommodated. It also includes a tongue-shaped spring and a pressure plate. The tongue-shaped spring includes a fixing part that is fixedly connected to the side plate and an elastic part that extends obliquely downward from the fixing part to generate a downward elastic force. Tongue-shaped springs are respectively provided on two opposite inner walls of the side plate. The elastic part abuts against the end of the pressure plate to press and fix the evaporation tube and the tray body tightly.

[0007] In some preferred embodiments, the tongue-shaped spring and the water receiving tray are both integral structures.

[0008] In some preferred embodiments, the pressure plate includes a pressure plate body that abuts against the evaporator tube and reinforcing ribs disposed on the upper side of the pressure plate body.

[0009] In some preferred embodiments, reinforcing ribs are provided on two opposite long sides of the pressure plate body, the reinforcing ribs extend to the two ends of the pressure plate body, and the bottom end of the elastic part abuts between the reinforcing ribs on both sides.

[0010] In some preferred embodiments, the pressure plate body is a strip-shaped plate structure.

[0011] In some preferred embodiments, a buffer material is also provided between the pressure plate body and the evaporation tube.

[0012] In some preferred embodiments, a plurality of tongue-shaped springs and a plurality of corresponding pressure plates are provided in the water receiving tray, and each pressure plate abuts against the bottom end of the elastic part of one of the tongue-shaped springs.

[0013] In some preferred embodiments, the evaporation tube includes an inlet end, an outlet end, and an evaporation section connected in sequence between the inlet end and the outlet end; both the inlet end and the outlet end extend into a water receiving tray, and the evaporation section is laid and fixed on the tray.

[0014] In some preferred embodiments, the evaporation section includes multiple straight pipes and multiple U-shaped bends for connecting the ends of two adjacent straight pipes.

[0015] This utility model also discloses a refrigeration device, including a cabinet with a refrigeration space, a compressor, a condenser and an evaporator, wherein the condenser, evaporator and compressor are respectively disposed in the cabinet; it also includes the aforementioned water receiving tray assembly, wherein the evaporation pipe is connected between the outlet of the compressor and the inlet of the condenser.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When using the pressure plate to press and fix the evaporator tube to the plate, simply place the pressure plate between the two tongue-shaped springs and apply a downward force to the pressure plate. The downward elastic force generated by the elastic parts of the two tongue-shaped springs will press the two ends of the pressure plate down onto the evaporator tube, thus pressing and fixing the evaporator tube to the plate. The assembly is firm and will not damage the evaporator tube.

[0018] 2. The downward elastic force generated by the elastic part reduces or even completely eliminates the friction between the evaporator tube and the pressure plate and the tray body when the evaporator tube vibrates, ensuring that the evaporator tube will not be damaged by vibration and friction during long-term use, further improving the reliability of the water tray assembly and ensuring that the refrigeration equipment has reliable and durable refrigeration performance.

[0022] Figure 4 This is a schematic diagram of the internal structure of the water tray assembly. Detailed Implementation

[0023] To further illustrate the technical means and effects adopted by this application to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0024] This utility model proposes a water tray assembly for refrigeration equipment, aiming to at least solve the technical problem in the prior art where the unreasonable installation structure of the evaporator tube and water tray leads to easy damage and affects the reliability of operation.

[0025] Refrigeration equipment can be refrigerators, freezers, refrigerated display cases, or refrigerated wine cabinets, etc., including a cabinet with refrigeration space, a compressor, a condenser, and an evaporator. The condenser, evaporator, and compressor are respectively installed in the cabinet and connected by an evaporation pipe. The refrigerant circulates in the evaporation pipe to circulate among the condenser, evaporator, and compressor to form a refrigeration system.

[0026] The cabinet includes a door and has one or more refrigerated compartments inside. The refrigeration equipment provides a defrosting function, which melts the frost formed by the condensation of moisture in the air on the evaporator surface into frost water. The refrigeration equipment also includes a drip tray assembly for receiving and collecting the frost water.

[0027] Combination Figures 1-4 As shown, the water receiving tray assembly includes a water receiving tray 1 and an evaporation tube 2. The water receiving tray 1 includes a tray body 11 and a side plate 12 surrounding the tray body 11. The tray body 11 and the side plate 12 surround each other to form an upward-facing water receiving cavity. The evaporation tube 2 is partially accommodated in the water receiving cavity. The water receiving tray assembly also includes a tongue-shaped spring 3 and a pressure plate 4. The tongue-shaped spring 3 includes a fixing part 31 fixedly connected to the side plate 12 and an elastic part 32 extending obliquely downward from the fixing part 31 to generate a downward elastic force. Tongue-shaped springs 3 are respectively provided on two opposing inner walls of the side plate 12. The elastic part 32 abuts against the end of the pressure plate 4 to press and fix the evaporation tube 2 to the tray body 11.

[0028] Compared with the existing technology that uses buckles with upward-facing slots to fix the evaporator tube 2, the water receiving tray assembly of this utility model has the following beneficial technical effects:

[0029] 1. Easy to assemble and securely fixed. Since the two tongue-shaped spring pieces 3 fixed to the two opposing inner walls of the side plate 12 are arranged opposite each other, and the elastic portion 32 of the tongue-shaped spring pieces 3 extends obliquely downwards, when the evaporator tube 2 and the plate body 11 are pressed and fixed by the pressure plate 4, it is only necessary to place the pressure plate 4 between the two tongue-shaped spring pieces 3, and then apply a downward force to the pressure plate 4. The end of the pressure plate 4 applies a downward force to the upper surface of the elastic portion 32, causing the elastic portion 32 of each of the two tongue-shaped spring pieces 3 to deform in a direction away from each other. Until the end of the pressure plate 4 further extends downwards past the bottom end of the elastic portion 32, the elastic portion 32 of each of the two tongue-shaped spring pieces 3 undergoes elastic recovery deformation. The bottom end of the elastic portion 32 abuts against the upper surface of the end of the pressure plate 4, thereby using the downward elastic force generated by the elastic portion 32 of each of the two tongue-shaped spring pieces 3 to press the two ends of the pressure plate 4 downwards onto the evaporator tube 2, achieving a secure and fixed assembly of the evaporator tube 2 and the plate body 11. The assembly is secure and will not damage the evaporator tube 2.

[0030] 2. Since the pressure plate 4 elastically abuts against the evaporator tube 2 via the tongue-shaped spring 3, when the evaporator tube 2 vibrates due to the operation of the compressor, the downward elastic force generated by the elastic part 32 can weaken or even completely eliminate the vibration of the evaporator tube 22. This ensures that the pressure plate 4 always presses the evaporator tube 2 tightly against the plate 11 under the action of the downward elastic force generated by the elastic part 32, preventing the evaporator tube 2 from vibrating and rubbing against the pressure plate 4 and plate 11 due to vibration. Therefore, the downward elastic force generated by the elastic part 32 weakens or even completely eliminates the friction between the evaporator tube 2 and the pressure plate 4 and plate 11 when the evaporator tube 2 vibrates, ensuring that the evaporator tube 2 will not be damaged by vibration friction during long-term use, further improving the reliability of the water tray assembly and ensuring that the refrigeration equipment has reliable and durable refrigeration performance.

[0031] The tongue-shaped spring 3 is usually a one-piece structure made of fatigue-resistant metals such as spring steel, which is simple in structure and durable. The fixing part 31 of the tongue-shaped spring 3 and the side plate 12 can be fixed by any existing method, including but not limited to screwing, riveting, welding, etc.

[0032] The pressure plate 4 is preferably made of rigid materials such as stainless steel, so that it will not bend or warp in the middle due to the force on both ends during long-term use, ensuring that all parts of the pressure plate 4 keep in contact with the evaporator tube 2.

[0033] The pressure plate 4 typically includes a pressure plate body 41 that abuts against the evaporator tube 2 and reinforcing ribs 42 provided on the upper side of the pressure plate body 41. Providing reinforcing ribs 42 has the following advantages: firstly, it improves the structural strength of the pressure plate body 41; secondly, it facilitates maintenance and replacement of the pressure plate 4 by increasing the points of force application during disassembly through the reinforcing ribs 42.

[0034] Reinforcing ribs 42 are provided on two opposite long sides of the pressure plate body 41, and the reinforcing ribs 42 extend to the two ends of the pressure plate body 41. The bottom end of the elastic part 32 is located between the two reinforcing ribs 42. The reinforcing ribs 42 on both sides can not only further improve the overall structural strength of the pressure plate 4, but also limit the elastic part 32 on both sides, so as to avoid the failure of the contact between the elastic part 32 and the pressure plate 4 due to improper assembly, thereby further improving the overall structural reliability.

[0035] The pressure plate body 41 usually adopts a strip-shaped plate structure, so that the pressure plate body 41 and the evaporator tube 2 have a large contact area, avoiding excessive pressure on the evaporator tube 2 due to the small contact area, which would damage the evaporator tube 2.

[0036] Furthermore, a buffer material (such as shock-absorbing cotton) can be placed between the pressure plate body 41 and the evaporator tube 2 to protect the evaporator tube 2.

[0037] To improve the clamping and assembly of the evaporator tube 2 using the pressure plate 4, multiple sets of tongue-shaped springs 3 and corresponding pressure plates 4 can be installed in the water receiving tray 1 as needed. For example, as shown in the attached diagram, the water receiving tray 1 adopts a rectangular strip structure. Inside the tray body 11, at each of the two ends along the length direction, there is a set of tongue-shaped springs 3 and two corresponding pressure plates 4, thereby using the two plates 4 to clamp and assemble the evaporator tube 2.

[0038] The water receiving tray 1 can be a rectangular structure as shown in the attached diagram, or it can be square, round, or other shapes; there are no restrictions here.

[0039] Furthermore, to ensure that the water receiving cavity does not leak, the water receiving tray 1 is usually made of one piece.

[0040] Understandably, the evaporator tube 2 includes a metal tube used to transport refrigerant. When the evaporator tube 2, located in the water receiving chamber, is transporting high-temperature refrigerant, the high-temperature refrigerant transfers heat to the frost in the water receiving pan 1, thereby evaporating the frost.

[0041] The evaporator tube 2 includes an inlet end 21, an outlet end 22 connected in sequence, and an evaporation section 23 connected between the inlet end 21 and the outlet end 22; the inlet end 21 is connected to the outlet of the compressor of the refrigeration equipment, and the outlet end 22 is connected to the inlet of the condenser of the refrigeration equipment; both the inlet end 21 and the outlet end 22 extend into a water receiving tray 1, and the evaporation section 23 is laid and fixed on the tray body 11 of the water receiving tray 1.

[0042] The evaporation section 23 may include multiple straight pipes 231 and multiple U-shaped bends 232 for connecting the ends of two adjacent straight pipes 231. This arrangement allows for a sufficiently long evaporation section 23 to be laid on the limited area of ​​the disc 11, thereby increasing the evaporation area of ​​the evaporation pipe 2 and improving the efficiency of evaporation of frost water in the evaporation section 23.

[0043] In addition, the equal spacing between the multiple straight pipes 231 can effectively improve the uniformity of the evaporation water in the evaporation section 23.

[0044] To facilitate fixing the water tray 1 inside the refrigeration equipment, an assembly 5 is provided on the outer side of the water tray 1. For example, the assembly 5 is provided with an assembly hole 51, and the water tray assembly is fixedly assembled inside the refrigeration equipment by passing screws through the assembly hole 51.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
