Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a water receiving tray structure of a refrigerator. Background Art

[0002] After prolonged operation, refrigerators generate condensation, which drains through a pipe into an external drain pan. Currently, the primary method for treating this condensation is to utilize the residual heat from the refrigeration system's exhaust evaporator to evaporate it and prevent it from overflowing. However, due to exhaust temperature limitations, the amount of water that can be evaporated is limited. In large refrigerators or humid environments, where condensation is high, the exhaust evaporator cannot fully evaporate the water in the drain pan, causing it to overflow and impacting user experience. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a refrigerator water receiving tray structure which ensures that the water in the water receiving tray is completely evaporated.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a refrigerator water receiving tray structure, which also includes a water receiving tray and an evaporator tube arranged in the water receiving tray and connected to the exhaust port of the refrigeration system compressor, including a heating wire arranged on the inner wall of the water receiving tray and spaced apart from the bottom of the water receiving tray, and a starting block that slides with the heating wire along the height direction of the water receiving tray, and the starting block can move with the water level and can turn on the heating wire below the water surface.

[0005] Furthermore, the starting block includes an insulator that can float on the water surface and a conductor arranged at the bottom of the insulator.

[0006] Furthermore, the starting block and the heating wire are slidably matched with each other in a concave-convex structure.

[0007] Furthermore, it also includes a limiting component arranged on the water receiving tray, and the starting block is located between the limiting component and the water receiving tray.

[0008] Furthermore, the limiting assembly includes at least two limiting bars which are spaced apart and have an L-shaped cross section, and the two side corners of the starting block are respectively plugged into and slidably engaged with the two limiting bars.

[0009] Furthermore, the evaporation tube is coiled in the water receiving tray.

[0010] Furthermore, the heating wire is attached to the inner wall of the water receiving tray in a spiral layer.

[0011] The beneficial effects of the present invention are as follows:

[0012] The water receiving tray structure of the refrigerator of the utility model is arranged with a heating wire spaced apart from the bottom of the water receiving tray. When the amount of water in the water receiving tray is small, heating and evaporation are performed through the evaporation tube. When the amount of water increases and part of the heating wire is immersed in the water, the starting block realizes the conduction of the underwater heating wire, so that the evaporation tube and the heating wire realize heating and evaporation synchronously, ensuring that the heat of the heating wire directly evaporates the water stored in the water receiving tray, thereby maximizing the heat utilization.

[0017] See also Figure 1 .

[0018] The utility model discloses a refrigerator water receiving tray structure, comprising a water receiving tray 1 and an evaporating tube 2 arranged in the water receiving tray 1 and connected to the exhaust port of the refrigeration system compressor, further comprising a heating wire 3 arranged on the inner wall of the water receiving tray 1 and spaced apart from the bottom of the water receiving tray 1, and a starting block 4 that slides with the heating wire 3 along the height direction of the water receiving tray 1, and the starting block 4 can move with the water level and can turn on the heating wire 3 located below the water surface.

[0019] The water receiving tray structure of the refrigerator of the utility model is provided with a heating wire 3 spaced apart from the bottom of the water receiving tray 1. When the amount of water in the water receiving tray 1 is small, heating and evaporation are performed through the evaporation tube 2. When the amount of water increases and the heating wire 3 is partially submerged in the water, the start block 4 turns on the underwater heating wire 4, so that the evaporation tube 2 and the heating wire 3 are heated and evaporated synchronously, ensuring that the heat of the heating wire 4 directly evaporates the water stored in the water receiving tray, thereby maximizing the heat utilization.

[0020] And wherein, the interval between the heating wire 4 and the bottom of the water receiving tray 1 is H1, and the water level in the water receiving tray is higher than H1 to achieve heating assistance of the heating wire 4;

[0021] And wherein, the position of the starting block 4 is provided with heating wires 4 on both sides, and the starting block 4 and the heating wires 4 form Figure 2 In the circuit shown, the starting block 4 is similar to a sliding rheostat. Moving the starting block 4 can realize the conductive connection and conductive length of the heating wires 4 on the left and right sides below the water surface.

[0022] In one embodiment, see Figure 1 The starter block 4 includes an insulator 401 that can float on the water surface and a conductor 402 arranged at the bottom of the insulator 401. This design allows the conductor 402 to be completely immersed below the surface of the water stored in the water receiving tray 1 and contact the heating wire 4, responsible for conducting the heating wire 4 below the water surface. The insulator 401 ensures that the starter block 4 can float on the surface of the water stored in the water receiving tray 1, so that the starter block 4 will not sink in the water and cannot float up and down due to the water level. The insulator 401 does not conduct the heating wire 4 above the water surface, ensuring that the heat of the heating wire 4 directly evaporates the water stored in the water receiving tray 1, thereby maximizing heat utilization. In addition, the insulator 401 can be made of a plastic plate with strong buoyancy, and the conductor 402 can be made of copper.

[0023] In one embodiment, see Figure 1 The starting block 4 and the heating wire 3 are in a concave-convex structure and slide in cooperation. In this way, the starting block is limited so that it slides along the height direction of the water receiving tray 1 when the water level changes.

[0024] In one embodiment, see Figure 1 , further comprising a limiting assembly 5 provided on the water receiving tray 1, and the starting block 4 is located between the limiting assembly 5 and the water receiving tray 1. This design further limits the starting block 4 to prevent the starting block 4 from floating freely in other directions.

[0025] In one embodiment, see Figure 1 The limiting assembly 5 includes at least two spaced-apart limiting bars 501 with an L-shaped cross section, and the corners of the actuator block 4 are respectively plugged into and slidably engaged with the two limiting bars 501. This design allows the two limiting bars 501 to limit the position of one side of the actuator block 4, resulting in a simple structure and good limiting effect.

[0026] In one embodiment, see Figure 1 , the evaporation tube 2 is coiled in the water receiving tray 1. This design extends the pipeline path of the evaporation tube 2 in the water receiving tray 1 and enhances the heating and evaporation effect of the evaporation tube 2.

[0027] In one embodiment, see Figure 1 The heating wire 3 is attached to the inner wall of the water receiving tray 1 in a spiral layer. This design extends the pipeline path of the heating wire 3 in the water receiving tray 1 and enhances the heating and evaporation effect of the heating wire 3.

[0028] In one embodiment, see Figure 2 , as shown in the electrical schematic diagram of the refrigerator water tray structure: the power supply, current stabilizer, and heating wire 3 are connected in series in the circuit. The current stabilizer is responsible for ensuring that the current in the circuit remains constant. The connection length of the heating wire 3 varies with the water level in the water tray 1. When the water level in the water tray 1 is lower than H1, the heating wire 3 does not participate in the work, and the temperature of the evaporation tube 2 evaporates the water. When the water level in the water tray 2 is higher than H1, the starting block 4 moves up as the water level in the water tray 1 rises, and the connection length of the heating wire 3 also increases. In this design, according to P=I 2 R (where: P: heating power, I: current passing through the heating wire, R: resistance of the heating wire), the current is guaranteed to be constant, and the resistance is proportional to the length of the heating wire 3. The longer the access length, the greater the resistance and the greater the heating power. That is, the heating wire 3 can adjust the heating power in real time according to the water storage capacity of the water receiving tray 1, and this scheme is adjusted to a linear and continuous adjustment. Energy consumption is reduced as much as possible while ensuring that the water stored in the water receiving tray can be evaporated, saving energy and improving user experience.
