Description

A moisturizing refrigerator

technical field

The utility model relates to a refrigerator, in particular to a refrigerator with the function of maintaining humidity.

Background technique

Ordinary refrigerators usually condense and freeze the moisture in the air in the refrigerator when cooling, thereby reducing the humidity in the refrigerator, resulting in the humidity in the box is often between 30% and 40%, and the best relative humidity for fruit, vegetable and meat storage It is between 80% and 90%, such as 83% for peaches and 85% to 90% for pork, etc. This will cause fruits, vegetables and meat to easily dry out in ordinary refrigerators and lose their original umami quality. And along with the trend of my country's gradual urbanization and the improvement of residents' living standards, people require refrigerators to have a very good fresh-keeping function in order to become a good assistant for home cooking to adapt to the fast-paced life. To have a good fresh-keeping effect, the humidity in the refrigerator must be kept at the optimum storage humidity, so as to solve the defects of air-dried fruits, vegetables and meat in ordinary refrigerators. But also do not have a kind of refrigerator with constant humidity to sell temporarily on the market.

In the above-mentioned moisturizing refrigerator, a drain port is provided on the side of the casing.

In the above-mentioned moisturizing refrigerator, the casing is arranged in the refrigerator compartment or in the fruit and vegetable area of the refrigerator compartment.

In the above-mentioned moisturizing refrigerator, the housing is arranged in the compressor compartment of the refrigerator, and the steam exhaust port is provided with a dehumidification pipe communicating with the refrigerating chamber.

In the above-mentioned moisturizing refrigerator, part of the pipe section of the condenser of the refrigeration system passes through the casing and is immersed in the water in the casing.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

1. The work of the humidifier is controlled by the refrigerator controller, so that the humidity in the refrigerator room or the fruit and vegetable room can be kept within a certain range, which is beneficial to the storage of fruits and vegetables.

2. The structure is simple and the process is easy to realize.

3. The user does not need manual operation during the humidification process, which is convenient to use.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Implementation Mode 1

As shown in Figure 1, a controller 108 with a CPU central processing unit is placed on the top of the back of the refrigerator cabinet. Lights, compressors and other components are connected. The refrigeration system of a refrigerator mainly includes a compressor, a condenser, a capillary tube, and an evaporator connected in sequence, and only the compressor is shown in FIG. 1 . A housing 103 with a humidifier is installed in the compressor compartment where the compressor is placed. The housing 103 has a water inlet and a steam outlet 109. The lower part of the housing 103 holds water. The humidifier consists of a heater at the bottom of the housing 103. 101 and the fan 104 on the casing 103 top. Above the fan 104 is a steam exhaust port 109, and then the steam exhaust port 109 is connected with the refrigerator with the moisture exhaust pipe 106, and a humidity sensor 107 is placed on the wall of the refrigerator chamber (or in the fruit and vegetable area), and the humidity sensor 107 collects Humidity in the box, the humidity sensor is connected to the controller and transmits the humidity data to the CPU central processing unit, and the CPU humidity data controls the humidifier to work. Its working process is as follows: when the refrigerator is cooling, the humidity in the refrigerator drops. At this time, the humidity sensor of the refrigerator will collect the humidity data in the refrigerator and send it to the refrigerator controller. The controller will calculate and compare with the set value. Humidity comparison (the set humidity can be preset before leaving the factory, or set by the user through the operation display on the door), if it is lower than the set humidity, the controller sends a control signal to make the heater 101 heats, and fan 104 starts, and the water vapor that heater produces in water heating passes through the twitching of fan like this, enters in the cold room (fruit and vegetable area) through dehumidifying pipe 106, makes its humidity rise. When the humidity reaches the set value, the controller sends a control signal to stop the heater and the fan to stop the humidification. Through such humidification control, the humidity in the box is maintained within the optimum range. In order to prevent the water in the housing from being insufficient, a liquid level sensor 102 is installed in the housing 103. When the water level in the housing 103 drops to a certain position, the liquid level sensor 102 conducts at a low level and transmits the information to the controller. Output control signal to buzzer alarm, and cut off the power supply of heater 101, stop heating. When the user adds too much water, the high level of the liquid level sensor 102 is turned on and transmitted to the controller, and the controller also outputs a control signal to the buzzer to alarm, telling the user to add too much water. Fig. 2 shows the structural layout of the humidifier, the housing 103 has a water inlet and a steam exhaust port 109, the heater 101 is placed at the bottom of the housing, 102 is a liquid level sensor, the fan 104 is on the top of the housing, and the steam exhaust port 109 Below, the drain port 110 is at about 2/3 of the height of the housing. Fig. 3 is the electrical control principle block diagram of humidifier in the utility model, controller 108 has CPU central processing unit, liquid level sensor 102 and humidity sensor 107 are connected with the input port of controller, heater 101, fan 104, alarm 201 It is connected to the output terminal of the controller, and its work is controlled by the controller.

Implementation mode two

As another embodiment of the present utility model, the humidifier part is placed inside the refrigerator compartment or the fruit and vegetable area of the refrigerator compartment, and the water vapor produced by heating the water by the heater 101 is directly discharged to the refrigerator compartment (the fruit and vegetable area) from the steam outlet. ), the dehumidifying pipe 106 shown in Fig. 1 in order to be communicated with the steam outlet 109 with the refrigerating chamber can be cancelled. Others such as the control method for the operation of the humidifier 101 and the internal structure of the casing 103 are the same as the above-mentioned solutions and will not be described in detail.

Implementation Mode Three

In the refrigeration system of the refrigerator, the high-temperature and high-pressure refrigerant coming out of the compressor is cooled in the condenser, so the temperature of the condenser pipe is relatively high. If a part of the heat of the condenser is transferred to the water in the shell, the heater can be reduced 101 working hours, saving electricity and improving the efficiency of the condenser. For this reason, on the basis of Embodiment 1, a condensing pipe section connected to the outlet of the compressor is inserted from the top of the casing 103 and immersed in the water in the casing to form a U-shaped elbow. During the operation of the compressor , to heat the water in the shell.
