Description

Technical Field

[0001] This application relates to the field of refrigerator structure technology, and in particular to a refrigerator. Background Technology

[0002] Refrigeration typically preserves food by cooling it down, which reduces the rate of respiration in plants and the rate of bacterial growth, thus extending the shelf life of food. However, with prolonged use, frost may condense on the evaporator inside the refrigerator, reducing the moisture in the refrigerator compartment. This leads to a continuous decrease in humidity, making it impossible to provide higher humidity levels and severely affecting the freshness of food. At the same time, existing humidification methods still suffer from poor humidification performance. Utility Model Content

This allows the liquid transmission pipe to collect the defrost water flowing from the evaporation module. Simultaneously, the defrost water in the collection module can flow into the humidification module, where it can be evaporated into the refrigerator compartment.

[0026] Hereinafter, embodiments will be described with reference to the accompanying drawings, which are not intended to limit the disclosure described in the claims.

[0027] Please see Figure 1 The following is combined with Figure 1 A refrigerator provided in the embodiments of this application will be described in detail.

[0028] This application provides a refrigerator, such as... Figure 1 As shown, specifically, the refrigerator includes a refrigerator shell 1, and an evaporation module 2, a defrosting heating module 3, a humidification module 4, and a defrosting water collection module 5 disposed within the refrigerator shell 1.

[0029] The defrosting heating module 3 has its heating port facing the evaporation module 2. The defrosting heating module 3 is used to heat the evaporation module 2 so that the frost on the evaporation module 2 melts and forms defrost water. The water outlet of the evaporation module 2 is connected to the input port of the humidification module 4 through the liquid transmission pipe 7. The defrost water collection module 5 is located on the liquid transmission pipe 7. The defrost water collection module 5 is used to collect the defrost water flowing out of the evaporation module 2 and transfer the collected defrost water to the humidification module 4. The output port of the humidification module 4 is facing the refrigerator compartment inside the refrigerator shell 1. The humidification module 4 is used to evaporate the defrost water into the refrigerator compartment.

[0030] In this embodiment, the evaporation module 2 can be an evaporator. During the operation of the refrigerator, frost will form on the evaporation module 2. If the frost on the evaporation module 2 is not cleaned for a long time, it will affect the performance of the refrigerator and consume more electricity. On the other hand, it will reduce the humidity in the refrigerator compartment, which will significantly reduce the preservation effect. Therefore, the defrosting heating module 3 heats the evaporation module 2 so that the frost on the evaporation module 2 can be melted by heat. The frost on the evaporation module 2 forms defrost water, which can reduce the impact on the performance of the refrigerator and reduce energy consumption. For example, the defrosting heating module 3 can be a device that provides heat.

[0031] Furthermore, the outlet of the evaporation module 2 is connected to the input port of the humidification module 4 via the liquid transmission pipe 7, and the defrost water collection module 5 is located on the liquid transmission pipe 7. The output port of the humidification module 4 is set towards the refrigerator compartment inside the refrigerator shell 1, so that the defrost water flowing out of the evaporation module 2 can be collected in the defrost water collection module 5 by the liquid transmission pipe 7. At the same time, there is an outlet in the defrost water collection module 5, which allows the defrost water in the defrost water collection module 5 to flow into the humidification module 4 when there is no obstruction at the outlet. Then, the defrost water can be evaporated into the refrigerator compartment by the humidification module 4 to improve the freshness of the food in the refrigerator compartment and extend the shelf life of the food. Furthermore, the defrost water can also be recycled, thereby saving energy.

[0032] It should be noted that the defrosting heating module 3 heats the evaporation module 2 intermittently. That is, the defrosting heating module 3 will stop heating the evaporation module 2 after a period of time to ensure the normal operation of the evaporation module 2.

[0033] In one specific implementation, see [link to implementation details]. Figure 1 The liquid transmission pipeline 7 is also equipped with a flow control valve 6, which is located between the defrost water collection module 5 and the humidification module 4. The flow control valve 6 is used to control the on / off connection between the defrost water collection module 5 and the humidification module 4.

[0034] In this embodiment, there may be no obstruction at the outlet of the defrost water collection module 5, meaning that the defrost water collection module 5 and the liquid transmission pipeline 7 are in a connected state. Therefore, a flow control valve 6 can be installed on the liquid transmission pipeline 7 between the defrost water collection module 5 and the humidification module 4 to control the connection and disconnection between the defrost water collection module 5 and the humidification module 4. When the flow control valve 6 is in the open state, the defrost water collection module 5 and the humidification module 4 are in a connected state, and when the flow control valve 6 is in the closed state, the defrost water collection module 5 and the humidification module 4 are in a disconnected state, thereby achieving water flow control.

[0035] In one specific embodiment, since the defrosting heating module 3 intermittently heats the evaporation module 2, and the humidification module 4 has a fixed capacity for defrosting water, when sufficient defrosting water is stored in the humidification module 4, the flow control valve 6 can be closed by the control module. The defrosting water can then be collected by the defrosting water collection module 5. When the defrosting water in the humidification module 4 decreases to a certain amount or when the defrosting water in the defrosting water collection module 5 does not flow into the humidification module 4 after a preset time interval, the flow control valve 6 can be opened by the control module. The defrosting water in the defrosting water collection module 5 can then flow into the humidification module 4 through the liquid transmission pipe 7. The humidification module 4 can then evaporate the defrosting water into the refrigerator compartment to improve the freshness of the food in the refrigerator compartment and extend its shelf life.

[0036] In practical applications, the flow control valve 6 is electrically connected to the control module. For example, the flow control valve 6 can be a solenoid valve.

[0037] In one specific implementation, the defrost water collection module 5, the flow control valve 6, and the humidification module 4 are arranged sequentially along the direction of gravity.

[0038] Specifically, by sequentially arranging the defrost water collection module 5, the flow control valve 6, and the humidification module 4 along the direction of gravity, the defrost water in the defrost water collection module 5 can flow into the humidification module 4 spontaneously due to gravity when the flow control valve 6 is open. This reduces the use of pumps and other devices, saving energy.

[0039] In one specific embodiment, the refrigerator casing 1 has a refrigerator compartment, which includes a refrigeration layer located at the bottom of the refrigerator compartment.

[0040] Specifically, there can be multiple refrigeration layers. For example, there can be two or three refrigeration layers. The defrosting water can be evaporated into multiple refrigeration layers through the humidification module 4 to humidify the food in multiple refrigeration layers and extend the shelf life of the food in multiple refrigeration layers.

[0041] In practical applications, multiple refrigeration layers can be stacked sequentially or spaced apart.

[0042] In one specific implementation, the diameter of the outlet of the evaporation module 2 decreases sequentially along the end closest to the liquid transmission pipe 7.

[0043] Specifically, the diameter of the outlet of the evaporation module 2 decreases sequentially along the end closest to the liquid transmission pipe 7 to collect the defrosting water flowing out of the evaporation module 2. Specifically, the diameter of the end of the outlet of the evaporation module 2 closest to the liquid transmission pipe 7 is the same as the diameter of the liquid transmission pipe 7 to prevent defrosting water from flowing out from the connection.

[0044] In one specific embodiment, the refrigerator further includes a water level detection device and a control module. The control module is electrically connected to the water level detection device and the flow control valve 6, respectively. The water level detection device is installed in the humidification module 4. The water level detection device is used to detect the water level data in the humidification module 4 and transmit the water level data to the control module so that the control module controls the opening and closing of the flow control valve 6 according to the water level data.

[0045] In this embodiment, the water level detection device can be a water level sensor. By setting up the water level detection device, the water level data in the humidification module 4 can be detected. The control module can then control the opening and closing of the flow control valve 6 based on the water level data to control the amount of water flowing into the humidification module 4, thereby preventing excessive water from flowing into the humidification module 4 and affecting its normal operation.

[0046] In practical applications, when the water level detection device detects that the water level in the humidification module 4 is lower than the first preset water level threshold, it indicates that there is less defrost water in the humidification module 4. The control module then controls the flow control valve 6 to be open so that the defrost water in the defrost water collection module 5 can flow into the humidification module 4. When the water level detection device detects that the water level in the humidification module 4 is higher than the second preset water level threshold, it indicates that there is more defrost water in the humidification module 4. The control module then controls the flow control valve 6 to be closed so as to prevent the defrost water in the defrost water collection module 5 from flowing into the humidification module 4, thereby achieving precise control of the defrost water flow.

[0047] The first preset water level threshold is less than the second preset water level threshold.

[0048] In one specific embodiment, the refrigerator further includes a humidity detection device; wherein, the humidity detection device is disposed inside the refrigerator compartment, the humidity detection device is electrically connected to the control module, the humidity detection device is used to detect the humidity data inside the refrigerator compartment, and transmit the humidity data to the control module, so that the control module controls the working state of the humidification module 4 according to the humidity data.

[0049] In this embodiment, the humidity detection device can be a humidity sensor. By setting up the humidity detection device, the humidity data in the cold storage layer can be detected, so that the control module can control the working state of the humidification module 4 according to the humidity data, thereby achieving precise control of the working state of the humidification module 4.

[0050] In practical applications, when the humidity detection device detects that the humidity data in the refrigerator compartment is lower than the first preset humidity threshold, it indicates that the humidity in the refrigerator compartment is too low, and the control module controls the humidification module 4 to be in operation. When the humidity detection device detects that the humidity data in the refrigerator compartment is higher than the second preset humidity threshold, it indicates that the humidity in the refrigerator compartment is too high, and the control module controls the humidification module 4 to be in a stopped operation state to avoid the humidity in the refrigerator compartment being too high, thus achieving precise control of the humidity in the refrigerator compartment.

[0051] The first preset humidity threshold is smaller than the second preset humidity threshold.

[0052] In one specific embodiment, the humidification module 4 is located outside the refrigerator layer, and the output port of the humidification module 4 is connected to the refrigerator layer through a water vapor transmission pipe, with the end of the water vapor transmission pipe extending into the refrigerator layer.

[0053] In this embodiment, the humidification module 4 can be placed outside the refrigerator layer. By connecting the output port of the humidification module 4 to the refrigerator layer through a steam transmission pipe, and extending the end of the steam transmission pipe into the refrigerator layer, steam can be transmitted to the refrigerator layer to preserve the food in the refrigerator layer.

[0054] In another specific embodiment, the humidification module 4 is located inside the cold storage layer, and a humidification spray element is provided at the output port of the humidification module 4. The humidification spray element is used to evenly spray the evaporated defrost water into the cold storage layer.

[0055] In this embodiment, the humidification module 4 can be installed inside the refrigerator layer, so that the food in the refrigerator layer can be kept fresh without the need for a water vapor transmission pipe. Thus, the humidification module 4 located inside the refrigerator layer can spray the evaporated defrost water evenly into the refrigerator layer through the humidification sprayer to keep the food in the refrigerator layer fresh.

[0056] In one specific embodiment, the refrigerator further includes a liquid container 9, which is connected to the top of the defrost water collection module 5 via a liquid guiding channel 8.

[0057] In this embodiment of the application, by setting up a liquid container 9, excess defrosting water can be contained in the liquid container 9, thereby avoiding the situation where the defrosting water in the evaporation module 2 cannot flow out when there is too much defrosting water.

[0058] Specifically, when too much defrost water flows out of the evaporation module 2, the defrost water collection module 5 will be full. The excess defrost water will flow out of the defrost water collection module 5. Then, the liquid guiding channel 8 can be used to introduce the defrost water that the defrost water collection module 5 cannot hold into the liquid container box 9 to ensure the normal operation of the refrigerator.

[0059] The above embodiments of this application have the following beneficial effects:

[0060] This application incorporates a defrosting heating module, a humidification module, and a defrosting water collection module. The evaporation module is connected to the humidification module via a liquid transmission pipe, and the defrosting water collection module is located on the liquid transmission pipe. This allows the defrosting water flowing from the evaporation module to be collected in the defrosting water collection module. Simultaneously, the defrosting water in the collection module can flow into the humidification module, where it can be evaporated into the refrigerator compartment. This improves the freshness of food in the refrigerator compartment, extends its shelf life, and further enables the recycling of defrosting water, thereby saving energy.
