Description

Technical Field

[0001] The invention relates to a temperature and humidity control device. Background Art

[0002] Some items are sensitive to temperature and humidity, so the temperature and humidity control is relatively strict when storing these items. In order to achieve the refrigeration function, ordinary storage equipment generally places the evaporator of the refrigeration system in the storage space, and blows cold air into the storage space to achieve the temperature drop in the storage space. Similarly, in order to achieve the thermal insulation function, ordinary storage equipment generally blows hot air into the storage space to achieve the temperature rise in the storage space. Whether it is refrigeration or thermal insulation storage, both use the airflow to exchange heat with the gas in the storage space. Directly discharging the airflow for heat exchange will cause a sudden change in the temperature of the local location, and will also cause rapid changes in humidity, which is not conducive to the storage of items that are sensitive to temperature and humidity.

The compressor 310, the throttling device 330, and the evaporation device 340 are all located on the frame 100, the storage cavity 210 has a forward opening, and a door panel 240 capable of closing or opening the opening is rotatably provided on the box body 200.

[0029] The temperature and humidity control equipment utilizes the evaporation device 340 of the refrigeration system 300 to cool the liquid in the heat exchange container 400. The pump body 600 circulates the liquid in the heat exchange container 400 to the heat exchange tube 500. The heat exchange tube 500 exchanges heat with the box body 200, thereby cooling the air in the storage cavity 210. This can ensure that the temperature and humidity in the storage cavity 210 are uniform, and can avoid sudden changes in temperature and humidity, thereby providing a stable temperature and humidity environment for the items.

[0030] See also Figure 3 and Figure 4 In some embodiments of the present invention, the evaporation device 340 includes a coil connected to the throttling device 330, and the coil is wound on the outer circumferential surface of the heat exchange container 400. In this embodiment, the heat exchange container 400 is roughly cylindrical, the throttling device 330 is a capillary tube, the input end of the coil is connected to the capillary tube, and the output end of the coil is connected to the compressor 310. The coil is wound along the height direction of the circumferential outer wall of the heat exchange container 400, so that the coil can be close to the outer wall of the heat exchange container 400 to exchange heat, which helps to quickly cool the liquid in the heat exchange container 400.

[0031] See also Figure 1 and Figure 3 In some embodiments of the present invention, in order to improve the utilization rate of the cold energy emitted by the evaporation device 340, the outer cover of the heat exchange container 400 is provided with an insulation shell 700, and a closed space is formed between the insulation shell 700 and the outer wall of the heat exchange container 400. The cold air in the closed space exchanges heat with the outer wall of the heat exchange container 400.

[0032] See also Figure 4 Since the liquid in the heat exchange container 400 will cause impurities to be generated in the pipeline after a period of circulation, the heat exchange efficiency of the liquid carrying impurities will be reduced. Therefore, in some embodiments of the present invention, the upper part of the heat exchange container 400 is provided with a liquid inlet pipe 410, and the lower part of the heat exchange container 400 is provided with a sewage pipe 420. The liquid inlet pipe 410 and the sewage pipe 420 can be detachably installed with sealing plugs, and the upper part of the heat exchange container 400 is provided with a gas pressure relief valve 430. After removing the sealing plug corresponding to the sewage pipe 420, the liquid in the heat exchange container 400 can be discharged from the sewage pipe 420, and then the sealing plug corresponding to the sewage pipe 420 is installed, and the sealing plug corresponding to the liquid inlet pipe 410 is removed, so that the liquid in the heat exchange container 400 can be replaced by injecting liquid from the outside. When the liquid is injected into the heat exchange container 400, in order to achieve pressure balance inside and outside the heat exchange container 400, part of the gas can be discharged from the gas pressure relief valve 430.

[0033] See also Figure 5 In some embodiments of the present invention, the heat exchange container 400 is provided with a partition 460 that can separate its inner cavity into an upper cavity and a lower cavity, and a gap 470 for fluid to pass through is provided between the partition 460 and the inner wall of the heat exchange container 400, and the gap 470 connects the upper cavity and the lower cavity. The liquid entering from the liquid inlet pipe 410 can pass through the gap 470, and in this process, the liquid can quickly exchange heat with the inner wall of the heat exchange container 400, thereby improving the heat exchange efficiency of the heat exchange container 400.

The temperature sensor senses the temperature information in the storage cavity 210 and feeds the information back to the control module 450. The user sets the temperature through an APP program on a mobile terminal such as a mobile phone. After the wireless communication module receives the temperature setting information, the control module 450 adjusts the power of the heating component 440 or the refrigeration system 300 so that the temperature in the storage cavity 210 can match the set temperature. Of course, in other embodiments, the temperature setting can also be directly input on the input panel connected to the control module 450 for setting.

[0037] See also Figure 1 In some embodiments of the present invention, in order to prevent the humidity in the storage cavity 210 from being reduced due to the liquefaction of the water vapor in the storage cavity 210, thereby affecting the storage effect, the inner wall of the box body 200 is provided with a humidifying component and a humidity sensor located in the storage cavity 210, and the humidity sensor and the humidifying component are both electrically connected to the control module 450. When the humidity sensor senses that the humidity in the storage cavity 210 is too low, the control module 450 controls the humidifying component to work, thereby increasing the humidity to a set value. In this embodiment, the temperature sensor and the humidity sensor are integrated into one to form the temperature and humidity sensor 250.

[0038] See also Figure 1 In this embodiment, a drainage groove 201 is provided on the inner bottom surface of the box body 200, and a drainage pipe 202 extending downward is connected to the drainage groove 201.

The blowing device 230 blows the gas in the closed shell into the box body 200, and the gas is discharged from the exhaust port 203 to form a circulation, which helps to improve the temperature uniformity of various positions in the storage cavity 210.

[0040] In this embodiment, the blowing device 230 includes a cross-flow fan blade driven by a motor. When the storage cavity 210 needs to be disinfected and sterilized, the control module 450 can control the ozone generator to work, and then the ozone is quickly delivered to every corner through the blowing device 230.
