DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0022] See also Figure 1 、 Figure 2 As shown, the present invention mainly relates to: a refrigeration device 100, including a refrigeration system, a box carrying the refrigeration system, an evaporating dish 111 provided in conjunction with the refrigeration system, and a water pipe 112 connected to the interior of the evaporating dish 111, the refrigeration system including a compressor 101, a condenser 102, a first capillary tube 104, and an evaporator 103 connected by pipelines, and also including a heating tube 108 connected to the outlet end of the compressor 101, a second capillary tube 105 connected to the outlet end of the heating tube 108, the pipeline including a first pipeline 109 provided in parallel with the second capillary tube 105 between the heating tube 108 and the condenser 102, a second pipeline 110 connected in parallel with the first capillary tube 104 between the condenser 102 and the evaporator 103, a first valve 106 for controlling communication between the second capillary tube 105 and the first pipeline 109, and a second valve 108 for controlling communication between the first capillary tube 104 and the second pipeline 110.

[0023] In the present invention, the first valve can be set at the inlet end of the second capillary 105 and the first pipeline 109, or at the outlet end of the second capillary 105 and the first pipeline 109. Correspondingly, the second valve can be set at the inlet end of the first capillary 104 and the second pipeline 110, or at the outlet end of the first capillary 104 and the second pipeline 110.

[0024] Combine Figure 1 As shown, in one embodiment of the present invention, the first valve 106 is connected to the first pipeline 109 and is arranged at the inlet end of the second capillary tube 105 and the first pipeline 109. The second valve 108 is connected to the first capillary tube 104 and is arranged at the outlet end of the first capillary tube 104 and the second pipeline 110. At this time, the defrost water / condensed water in the evaporating dish 111 is in a normal evaporation state.

[0025] Combine Figure 2 As shown, in one embodiment of the present invention, first valve 106 connects second capillary tube 105 and is located between the inlet of second capillary tube 105 and first pipeline 109. Second valve 108 connects second pipeline 110 and is located between the outlet of first capillary tube 104 and second pipeline 110. In this state, the defrosted water / condensed water in evaporating dish 111 is in an accelerated evaporation state. When second capillary tube 105 is connected, the condensation end of second capillary tube 105 is connected to heating tube 108 of evaporating dish 111. The higher the temperature of the heating tube in evaporating dish 111, the faster the evaporation of water in evaporating dish 111.

[0026] It should be noted that, in the present invention, the heating tube 108 can be disposed inside the evaporating dish 111 , at the bottom of the evaporating dish 111 , or around the periphery of the evaporating dish 111 .

[0027] Preferably, the heating tube 108 is disposed inside the evaporating dish 111 .

[0028] See also Figure 3 、 Figure 4 As shown, in the present invention, the refrigeration device 100 further includes a steam delivery device 200, and the steam delivery device 200 includes a cover plate 201 with an air outlet and a water vapor conduit 202 adapted to the air outlet.

[0029] Preferably, the water vapor conduit 202 near the gas outlet is in an inverted funnel shape, so that a portion of water vapor can be accumulated at the gas outlet to continuously provide the water vapor conduit 202 with generated water vapor.

[0030] Furthermore, a refrigeration compartment (not shown) is provided in the box, and the water vapor conduit 202 of the steam delivery device 200 leads to the refrigeration compartment, so that the generated water vapor can be used to humidify the refrigeration compartment to keep food fresh.

[0031] Combine Figure 3 As shown, in one embodiment of the present invention, the water pipe 112 guides the defrost water or condensed water at the evaporator 103 in the refrigeration system to the bottom of the evaporating dish 111, so that the water pipe 112 is below the liquid level to prevent water vapor from escaping from the water pipe 112.

[0032] Preferably, the cover plate 201 is located directly above the evaporating dish 111, and the width of the water conduit 112 is equal to the width of the cover plate 201 and the width of the evaporating dish 111, thus forming a relatively closed evaporation zone, which can fully utilize the evaporated water vapor to humidify the refrigerated compartment.

[0033] Combine Figure 4As shown, in an embodiment of the present application, the evaporation tray 111 is provided with a partition plate 113, which divides the evaporation tray 111 into a first evaporation area 1111 and a second evaporation area 1112, and the cover plate 201 is arranged higher than the partition plate 113, so that when the defrosting water / condensed water entering the first evaporation area 1111 is relatively large, the excess water is guided into the second evaporation area 1112.

[0034] Preferably, the water guide pipe 112 guides the defrosting water or condensed water at the evaporator 103 in the refrigeration system to the bottom of the first evaporation area 1111 of the evaporation tray 111, so that the water guide pipe 112 is below the liquid level, preventing water vapor from exiting the water guide pipe 112.

[0035] Further, the steam conveying device 200 is connected to the first evaporation area 1111 of the evaporation tray 111, i.e., the water vapor generated in the first evaporation area 1111 is guided into the refrigeration compartment.

[0036] In this embodiment, the defrosting water or condensed water is guided by the water guide pipe 112 to the first evaporation area 1111 of the evaporation tray 111, and the water vapor generated in the first evaporation area 1111 is guided into the refrigeration compartment by the steam conveying device 200 for humidification and food preservation. When the defrosting water or condensed water is relatively large, it passes through the partition plate 113 and enters the second evaporation area 1112 for evaporation, and then is discharged into the air, avoiding the occurrence of overflow caused by excessive accumulation of water, and also avoiding excessive humidity in the cabinet.

[0037] In combination Figure 5 As shown, in the present application, a humidity sensor 114 is arranged in the refrigeration compartment to detect the humidity of the refrigeration compartment, and the evaporation speed of the defrosting water / condensed water at the evaporation tray can be controlled according to the humidity of the refrigeration compartment.

[0038] Further, the refrigeration device 100 further comprises a controller 115 configured to control the communication direction of the first valve 106 and the second valve 107, so as to realize real-time control of the evaporation speed of the evaporation tray 111 through different communication directions.

[0039] Specifically, when the humidity value detected by the humidity sensor is less than or equal to a preset humidity value, the first valve 106 is controlled to be conductive to the first pipeline 109, and the second valve 108 is controlled to be conductive to the first capillary tube 104; when the humidity value detected by the humidity sensor 114 is greater than the preset humidity value, the first valve 106 is controlled to be conductive to the second capillary tube 105, and the second valve 108 is controlled to be conductive to the second pipeline 110.

[0040] Preferably, the preset humidity value is 45%.

[0041] In addition to controlling the evaporation rate of defrost water / condensate according to the humidity of the refrigerated compartment, the evaporation mode can also be adjusted according to the quality of the defrost water / condensate. For example, a weight sensor can be set at the evaporating dish. Of course, it can also be controlled according to time, temperature, defrost water / condensate flow rate, etc.

[0042] The refrigeration device 100 of the present invention can be a refrigerator, a freezer, a wine cabinet, etc. The evaporating dish 111 can be fixed to one side of the compressor 101 or to the top of the compressor 101 and can be adjusted according to the space size of the refrigeration device 100.

[0043] Compared to existing technologies, the present invention adds an optional heating branch to the refrigeration system, such as a heating tube and a second capillary branch located between the compressor and condenser. This heating branch can be activated when rapid evaporation of defrost water or condensed water in the evaporating dish is required, thereby increasing the evaporation rate. By utilizing the high temperatures at the compressor and condenser end to heat and evaporate the defrost water or condensed water, this not only prevents overflow but also cools the compressor. Furthermore, the evaporated water vapor from the defrost water / condensed water is directed into the refrigeration unit's cold storage compartment, humidifying the compartment and preserving food freshness.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
