Description

Technical Field

[0001] The invention belongs to the technical field of refrigerators, and in particular relates to a humidifying refrigerator. Background Art

[0002] As people's material living standards improve, higher and higher requirements are placed on the freshness-keeping performance of refrigerators. In particular, when users store food with high moisture content such as fruits and vegetables, they need the refrigerator to provide a storage space with high humidity. Due to the characteristics of the refrigeration system, the refrigerator compartment of a single-system air-cooled refrigerator has a low humidity problem, which causes fruits and vegetables to lose water and wilt after long-term storage. At present, there are few humidification technologies for single-system air-cooled refrigerators on the market, and most of them are mechanically controlled moisturizing technologies for small spaces and small drawers, which have weak humidification effects. In addition, there is also humidification by adding water externally, which has an obvious moisturizing effect, but is less convenient for users. Therefore, consumers are in urgent need of a humidification technology that can solve the problem of the refrigerator compartment of a single-system air-cooled refrigerator.

[0003] The present invention provides a refrigerator with a humidification function for refrigerator users. Through the functions of a micro fan, a pipeline, a water storage box, a hygroscopic material and a metal material, the moisture in the hygroscopic material is evaporated into a refrigerating chamber through the micro fan, thereby increasing the humidity of the refrigerating chamber, thereby improving the storage quality of fruits and vegetables, meeting the freshness requirements of consumers, and being easy to operate. Summary of the invention

[0004] The object of the present invention is to provide a humidifying refrigerator, which solves the problem that the low humidity in the refrigerator compartment of the existing single-system air-cooled refrigerator easily causes the fruits and vegetables to lose water and wilt, and the humidification operation is inconvenient through the functions of a micro fan, a pipeline, a water storage box, a hygroscopic material and a metal material.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a humidifying refrigerator, comprising a refrigerating chamber, a freezing chamber and a refrigerator control system;

[0007] A pipe connected to the outside is installed in the cold storage room; one end of the pipe is the pipe air inlet; the other end of the pipe is the pipe air outlet, which is connected to the cold storage room, so that high-humidity air from the outside is sucked in through a micro fan, and at the same time it is convenient for the backflow of overflowed condensed water; a water storage box is fixedly installed on the pipe air outlet, and the two are connected; a plurality of openings are provided on one side of the water storage box; a refrigeration air duct and a refrigeration return air outlet are arranged in the cold storage room; a plurality of refrigeration air outlets are arranged at one end of the refrigeration air duct; a freezing evaporator and a refrigeration fan are installed in the freezer room; a compressor compartment is installed on one side of the freezer room; a micro fan is arranged in the pipe; the inner wall of the water storage box is provided with metal material; and a hygroscopic material is arranged in the water storage box.

[0008] Furthermore, a water receiving pan is provided below the pipeline air inlet for receiving condensed water overflowing from the water storage box; the pipeline air inlet and the water receiving pan are both located in the compressor compartment.

[0009] Furthermore, a humidity sensor is provided in the refrigerating chamber for detecting the humidity in the refrigerating chamber. When the humidity sensor detects that the humidity in the chamber is lower than a set value, the micro fan is started to replenish humidity.

[0010] Furthermore, the water storage box has a top cover and forms a closed cavity; a plurality of the openings form a grid structure; the lowest point of the openings is higher than the lowest point of the air outlet of the pipe, thereby preventing condensed water from overflowing into the refrigerated chamber.

[0011] Furthermore, the metal material covers the entire inner wall of the water storage box or covers part of the inner wall of the water storage box.

[0012] Furthermore, the pipe air outlet extends 10 mm to 50 mm into the water storage box; the pipe air outlet forms an angle of 10° to 60° with the outer wall of the water storage box.

[0013] Furthermore, a plastic bracket is fixedly installed in the water storage box; a plurality of hygroscopic materials are fixed on the plastic bracket; the hygroscopic materials are in a sheet-like structure;

[0014] The inner bottom surface and the inner top wall of the water storage box are connected to the plastic bracket;

[0015] One side of the hygroscopic material faces the air outlet of the pipeline; the other side of the hygroscopic material faces the opening, so as to facilitate moisture absorption and water evaporation and diffusion into the refrigerating chamber.

[0016] Furthermore, the hygroscopic material has a thickness of 0.1 to 2.0 mm, a porosity of 30% to 80%, and a water absorption rate of 50% to 90%; and the hygroscopic material is made of a material with antibacterial and mildew-proof properties.

[0017] Furthermore, the pipeline is buried in the foaming layer of the refrigerator.

[0018] Furthermore, the micro fan is arranged at any position in the pipeline; the micro fan is connected to the refrigerator control system, and when the micro fan is started, the air flow direction is from the external environment to the refrigeration chamber.

[0019] The present invention has the following beneficial effects:

[0020] The present invention introduces high-humidity air from the outside into a water storage box in a cold storage room through a pipe by a micro fan. When the high-humidity air contacts the metal material in the water storage box, it is condensed into condensed water. The condensed water flows to the bottom of the water storage box and is sucked into the hygroscopic material. At the same time, the moisture in the hygroscopic material is evaporated into the cold storage room by the micro fan, thereby increasing the humidity in the cold storage room, thereby improving the storage quality of fruits and vegetables, meeting the freshness-keeping needs of consumers, and the operation is convenient, and moisture can be replenished in time to ensure the quality of fruits and vegetables in the cold storage room.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Preferably, Figure 1 As shown, a humidity sensor 13 is provided in the refrigerating chamber 1 for detecting the humidity in the refrigerating chamber 1. When the humidity sensor 13 detects that the humidity in the refrigerating chamber is lower than a set value, the micro fan 17 is started to replenish humidity.

[0033] Preferably, Figure 1-2 As shown, the water storage box 15 has a top cover and forms a closed cavity; a plurality of openings 20 form a grid structure; the lowest point 21 of the openings 20 is higher than the lowest point 22 of the air outlet of the pipe air outlet 14 to prevent condensed water from overflowing into the refrigerating chamber 1.

[0034] Preferably, Figure 1-2 As shown, the metal material 16 covers the entire inner wall of the water storage box 15 or covers a portion of the inner wall of the water storage box 15 .

[0035] Preferably, Figure 1-2 As shown, the pipe air outlet 14 extends 10 mm to 50 mm into the water storage box 15; the pipe air outlet 14 and the outer wall of the water storage box 15 form an angle of 10° to 60°.

[0040] The working principle of the present invention is as follows: when the freezer compartment 2 is refrigerated and the refrigerator compartment 1 is not refrigerated, the refrigerator compartment 1 is at a slight negative pressure, and the external air enters the pipe 8 due to the pressure difference, and the external high-temperature and high-humidity air enters the water storage box 15. Since the inner wall of the water storage box 15 is covered with a metal material 16, the temperature of the high-temperature and high-humidity air decreases, and water vapor condenses on the surface of the metal material 16 to form condensation. With the continuous inflow of high-humidity air, more and more condensation is produced. The condensation flows along the surface of the metal material 16 to the bottom of the water storage box 15 and is sucked into the hygroscopic material 19. Turn on the micro fan 17 to blow toward the surface of the hygroscopic material 19, so that the liquid water in the hygroscopic material 19 evaporates into gaseous water and diffuses into the refrigerator compartment 1, thereby achieving the effect of humidification. When the compressor stops, turn on the micro fan 17 to replenish the water removed by the refrigeration of the refrigerator compartment 1. In addition, if the humidity sensor 13 in the refrigerating chamber 1 detects that the humidity in the chamber is lower than 10% to 30%, it indicates that the refrigerating chamber 1 needs humidification, and the micro fan 17 is turned on to force high-humidity air flow into the refrigerating chamber 1 for humidification; when the water level in the water storage box 15 rises to the pipe outlet 14, the overflowing condensed water flows from the pipe 8 to the water receiving tray 11 of the compressor compartment 5.
