Description

Technical Field

[0001] This utility model relates to the field of storage device technology, specifically a drainage device for refrigeration equipment. Background Technology

[0002] The drain pipe of refrigerated products connects the internal space of the box to the external water tray for drainage. If volatile and flammable gases are stored inside the box, they can flow to the compressor compartment through the drain pipe. The compressor compartment contains electrical components such as compressors and fans. When the concentration of flammable gases reaches a certain level, there is a risk of ignition by an electric spark or even an explosion, which seriously affects the safety of personnel and the environment. At the same time, the cold air inside the box will leak out through the drain pipe, which will increase the product's energy consumption and cause energy waste.

[0003] Furthermore, if the refrigerated products are designed without drain pipes, a drip tray must be placed inside the box, which requires manual emptying of water, making the operation cumbersome.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-3 This utility model provides a technical solution:

[0034] A drainage device for refrigeration equipment, comprising:

[0035] The refrigeration unit 1 includes a cabinet 11 for refrigerating refrigerated products;

[0036] The drainage unit 2 includes a transfer assembly 21 located at the outlet end of the housing 11 for draining water from the housing 11, and a valve assembly 22 located at the lower end of the transfer assembly 21 for controlling the drainage status of the housing 11 and preventing cold air from being discharged from the housing 11.

[0037] It should be noted that when drainage occurs inside the housing 11, initially, the valve assembly 22 is in a closed state. The housing 11 drains water through the adapter 21 into the valve assembly 22 for accumulation. When a certain level of water accumulates in the valve assembly 22, the valve assembly 22 automatically opens under the pressure of the water, allowing the water inside to be discharged. After a portion of the water is discharged, the valve assembly 22 closes again to ensure that the water inside the valve assembly 22 can prevent flammable gases inside the housing 11 from flowing into the compressor 16, thus preventing the risk of explosion, and also to prevent cold air inside the housing 11 from leaking out through the drain pipe, which would increase energy consumption.

[0038] As an improvement, such as Figure 1 As shown, the refrigeration unit 1 further includes:

[0039] Evaporator 13 is fastened to the rear end of housing 11 by liner 12 and is used to cool the interior of housing 11;

[0040] The connecting pipe 14 has its upper end sleeved on the outside of the adapter assembly 21 and its lower end inserted into the outside of the valve assembly 22, and is used to guide water from the adapter assembly 21 into the valve assembly 22.

[0041] The water receiving tray 15 is located below the valve assembly 22 and is used to collect the water discharged from the valve assembly 22.

[0042] Furthermore, a compressor 16 is provided directly below the valve assembly 22 for evaporating the water collected in the water receiving tray 15.

[0043] Furthermore, such as Figure 1 , Figure 3 As shown, the adapter component 21 includes:

[0044] A water inlet 211 is located at the lower end of the tank 11 and is used to drain the water from the tank 11.

[0045] A water pipe connector 212 is connected to the lower opening of the water receiving tank 211 and is used to guide water in the water receiving tank 211 into the valve assembly 22.

[0046] A limiting protrusion 213 is provided on the outside of the water pipe joint 212 to limit the sleeve position of the connecting pipe 14.

[0047] As an improvement, such as Figure 1-2 As shown, the valve assembly 22 includes:

[0048] The housing 221 is sleeved on the lower end of the connecting pipe 14. The upper end of the housing 221 is provided with a water inlet 2211 that communicates with the water pipe connector 212. The housing 221 has a receiving cavity 2212 in the middle inside.

[0049] A plug 222 is inserted into the bottom of the inlet 2211 and located inside the receiving cavity 2212 to seal the inlet 2211. A guide rod 2221 is fixedly connected to the middle of the lower end of the plug 222. A guide groove 2215 is provided inside the housing 221 and located at the lower end of the receiving cavity 2212 to guide the guide rod 2221.

[0050] Spring 224 is sleeved on the outside of guide rod 2221 and located between plug 222 and bottom of receiving cavity 2212, for tightening plug 222.

[0051] Furthermore, a drain outlet 2213 is provided at the lower end of the housing 221;

[0052] A water outlet 2214 is provided inside the housing 221 and between the receiving cavity 2212 and the drain outlet 2213, for guiding water from the receiving cavity 2212 into the drain outlet 2213.

[0053] Furthermore, a sealing ring 223 is fitted on the upper outer side of the plug 222 to cooperate with the plug 222 to seal the inlet 2211.

[0054] It should be noted that: in the specific implementation process of this utility model, if... Figure 1-3 As shown, initially, the plug 222 seals the lower opening of the inlet 2211 under the elastic force of the spring 224. When the tank 11 drains water, the tank 11 discharges water through the water receiving groove 211 into the water pipe joint 212. The water pipe joint 212 discharges water into the housing 221 through the connecting pipe 14 and is located above the plug 222. As the water level in the connecting pipe 14 increases, when the combined weight of the water pressure in the connecting pipe 14 and the plug 222 exceeds the elastic force of the spring 224, the water in the connecting pipe 14 pushes the plug 222 downward to gradually compress the spring 224, causing the plug 222 to move the sealing ring 223 and the bottom part of the inlet 2211. At this time, the water in the connecting pipe 14 falls into the water receiving tray 15 for collection after passing through the receiving cavity 2212, the water outlet 2214, and the drain outlet 2213 in sequence. When the water in the connecting pipe 14 drops to a certain height, so that the combined weight of the water pressure in the connecting pipe 14 and the plug 222 is less than the elastic force of the spring 224, the spring 224 pushes the sealing ring 223 through the plug 222 to seal the bottom of the water inlet 2211, so that the water in the connecting pipe 14 always has a certain liquid level to block the combustible gas or cold air in the box 11, which prevents the volatile combustible gas from flowing to the compressor 16 and causing an explosion, and also prevents the cold air in the box 11 from leaking out and increasing energy consumption.

[0055] like Figure 1As shown, in addition, the water collected in the water tray 15 is evaporated by the heat generated by the compressor 16 during operation, so there is no need to manually clean the water in the water tray 15.
