Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an installation structure of a water receiving tray assembly for a refrigerated display cabinet. Background Art

[0002] Currently, some refrigerated display cabinets have an evaporator located in the upper portion of the display cabinet. Below the evaporator is a drain pan to collect defrosted water. This water then flows through a drain pipe from the drain pan into a water sump in the machine compartment. Existing drain pipes are typically routed within the display cabinet's foam layer. This arrangement, however, places the drain pipe too close to the display cabinet's refrigeration tank, necessitating the installation of a heating device to prevent freezing and blockage. However, this heating device heats up the foam layer, which in turn raises the temperature of the display cabinet's refrigeration tank, increasing cooling power consumption. Therefore, improvements are necessary. Summary of the Invention

[0003] The purpose of the utility model is to provide an installation structure for a water receiving tray assembly for a refrigerated display cabinet, which can effectively ensure the timely discharge of defrost water without increasing power consumption, and effectively reduce refrigeration power consumption while ensuring the freezing temperature of the refrigerated display cabinet.

[0004] The purpose of this utility model can be achieved through the following technical solutions:

[0006] According to the optimized solution, the drain pipe also has a second pipe portion arranged vertically along the back of the cabinet, and a third pipe portion penetrating into the mechanical room. The first pipe portion, the second pipe portion and the third pipe portion are connected in sequence, and the end of the third pipe portion has a drain outlet, which is located above the water collection tray.

[0007] Furthermore, the third pipe portion has a U-shaped buffer pipe portion bent downward.

[0008] Furthermore, an outer cover for covering the second pipe portion is provided on the back side of the cabinet.

[0009] Further, the back of the cabinet body is provided with a plurality of clamping seats for positioning the second pipe part, the clamping seat has a clamping groove and is clamped on the outer wall of the second pipe part.

[0010] The optimization scheme has a water collecting bottom with a gradually narrowing from top to bottom on the bottom rear side of the water pan body, and the drain hole is arranged on the bottom rear side of the water collecting bottom.

[0011] The utility model has the following substantial features and progress: the utility model does not arrange the drain pipe for discharging defrosting water in the foaming layer of the cabinet body, thereby avoiding the drain pipe being too close to the freezer room, thereby effectively avoiding the defrosting water freezing under the influence of the low temperature of the freezer room during discharging along the drain pipe, so that it is not necessary to configure a heating device for the drain pipe, thereby reducing product cost and eliminating the loss of cold quantity of the freezer room caused by the heating device, while ensuring the freezing temperature of the freezer display cabinet, effectively reducing refrigeration power consumption and improving refrigeration efficiency.

[0018] EMBODIMENT

[0019] A kind of installation structure of water pan assembly for freezer display cabinet, it includes cabinet 1 and water pan assembly, the cabinet 1 is equipped with freezer room 11, the freezer room 11 is equipped with evaporator 2, the cabinet 1 is equipped with mechanical room 12 below freezer room 11, the mechanical room 12 is equipped with compressor 3 and water pan 4.

[0020] The water pan assembly comprises a water pan body 5 and a drain pipe. The water pan body 5 is in a disc shape with a water inlet at the top, and a drain hole 51 at the bottom rear side of the water pan body 5. The drain pipe has a first pipe section 61 which is downwardly inclined, and the front end of the first pipe section 61 is connected to the drain hole 51 of the water pan body 5. The water pan body 5 is located directly below the evaporator 2 in the cabinet 1, and the rear side of the water pan body 5 is close to the rear part of the cabinet 1. The end of the first pipe section 61 is arranged to pass through the rear part of the cabinet 1, so that the end of the first pipe section 61 is located on the back of the cabinet 1.

[0021] In the above structure, the water pan body 5 is used to collect defrosting water generated by the evaporator 2 during defrosting, and the defrosting water is drained along the drain pipe. The drain pipe is not arranged in the foaming layer 10 of the cabinet 1, so that the drain pipe is not too close to the freezer compartment 11, and the defrosting water is effectively prevented from freezing during the process of being drained along the drain pipe due to the low temperature of the freezer compartment 11.

[0022] Further, the bottom rear side of the water pan body 5 has a water collecting bottom 50 which is tapered from top to bottom, so that the defrosting water is concentrated in the water collecting bottom 50, and the defrosting water is easily drained. In addition, the drain hole 51 is arranged at the bottom rear side of the water collecting bottom 50, so that the drain pipe can pass through the rear part of the cabinet 1.

[0023] Further, the drain pipe further has a second pipe section 62 which is vertically arranged along the back of the cabinet 1, and a third pipe section 63 which passes through the mechanical chamber 12. The first pipe section 61, the second pipe section 62 and the third pipe section 63 are connected in sequence, and the end of the third pipe section 63 has a drain opening 64 which is located above the sump pan 4. In the above structure, the defrosting water is drained into the sump pan 4 in the mechanical chamber 12 along the first pipe section 61, the second pipe section 62 and the third pipe section 63 of the drain pipe, and the water in the sump pan 4 is evaporated by the high temperature of the mechanical chamber 12. At the same time, the evaporated water is beneficial to the cooling of the mechanical chamber 12.

[0024] Further, the third pipe section 63 has a U-shaped buffer pipe section 65 which is downwardly bent. The U-shaped buffer pipe section 65 is used to buffer the flow rate of the defrosting water falling into the sump pan 4, so that the falling water sound is reduced and water splashing is avoided.

[0025] Further, the back of the cabinet 1 is provided with an outer cover 7 which covers the second pipe section 62, so that the appearance of the back of the cabinet 1 is beautified.
