Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of humidity control of the internal environment of a storage cabinet, and in particular relates to a storage cabinet. Background Art
[0002] With the development of technology and the improvement of people's living standards, more and more items need to be stored. Specifically, some items need to be stored in a storage space with constant temperature and humidity conditions, such as tea, cigars, calligraphy and paintings, antiques, precision electronic instruments, medical equipment, etc. In order to prevent the above items from deteriorating or being damaged during long-term storage, a storage cabinet with constant temperature and humidity function is needed.
[0003] However, although the storage cabinet in the prior art has a constant temperature and humidity function, a gasification device for gasifying liquid water is usually set in the storage cabinet to humidify the storage cabinet. And a liquefaction device for liquefying gaseous water is set in the storage cabinet to dehumidify the storage cabinet. Specifically, the gasification device usually includes a water tank and a gasification device. The water tank is used to store water, and the gasification device is used to gasify liquid water in the water tank to humidify the inside of the storage cabinet. However, in order to ensure that the gasification device can humidify the storage cabinet at any time, it is necessary to have water in the water tank continuously, which requires water to be added to the storage cabinet. In addition, in order to avoid the situation where the storage cabinet is placed in a restricted position due to the need to connect the water inlet pipeline to the water tank of the storage cabinet, water is usually added to the water tank manually, which causes inconvenience in use.
[0004] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention
[0005] In order to solve the above problems in the prior art, that is, to solve the problem that the storage cabinet in the prior art needs to be manually filled with water, which causes inconvenience in use.
[0006] The present invention provides a storage cabinet, comprising a cabinet body, wherein a storage cavity for storing articles is formed inside the cabinet body, and the storage cabinet also comprises a humidity control module, which is arranged in the cabinet body and is configured to introduce gaseous water in the air outside the cabinet body into the storage cavity when humidifying the storage cavity, and to liquefy and then vaporize the gaseous water in the external air through the humidity control module to increase the air humidity of the air inside the storage cavity, and is also configured to liquefy and then vaporize the gaseous water in the air inside the storage cavity and discharge it to the outside of the cabinet body when dehumidifying the storage cavity to reduce the air humidity of the air inside the storage cavity.
[0007] In the case of adopting the above technical solution, when the air inside the storage cavity needs to be humidified, the gaseous water in the air outside the cabinet is first liquefied and then gasified and introduced into the storage cavity through the humidity control module to increase the air humidity of the air inside the storage cavity. When the air inside the storage cavity needs to be dehumidified, the gaseous water in the air inside the storage cavity can be first liquefied and then gasified and discharged to the outside of the cabinet to reduce the air humidity of the air inside the storage cavity. When the present invention controls the humidity of the air inside the storage cabinet, the gaseous water inside the storage cavity is exchanged with the gaseous water outside the cabinet through the humidity control module to control the air humidity inside the storage cavity. The above process does not require adding liquid water to the storage cabinet to humidify the inside of the storage cavity, and there is no need to manually add water to the storage cabinet, which makes it convenient for users to use and improves the user experience.
[0008] In the preferred technical solution of the above storage cabinet, the humidity control module includes:
[0009] a liquefaction unit for liquefying gaseous water, configured to liquefy gaseous water in the air outside the cabinet into first liquid water when the humidity control module humidifies the storage cavity, and further configured to liquefy gaseous water in the air inside the storage cavity into second liquid water when the humidity control module dehumidifies the storage cavity;
[0010] a vaporization unit for vaporizing liquid water, configured to vaporize the first liquid water to the storage cavity when the humidity control module humidifies the storage cavity, and further configured to vaporize the second liquid water and discharge it to the outside of the cabinet when the humidity control module dehumidifies the storage cavity;
[0011] The communication portion is disposed between the vaporization portion and the liquefaction portion and is configured to communicate the liquefaction portion and the vaporization portion so that the first liquefied water or the second liquefied water flows into the vaporization portion.
[0012] In the preferred technical solution of the above storage cabinet, the liquefaction unit includes:
[0013] A liquefaction chamber, which is arranged inside the cabinet;
[0014] a liquefaction element, which is disposed inside the liquefaction cavity and is used to liquefy the gaseous water inside the liquefaction cavity into the first liquid water or the second liquid water;
[0015] A first air inlet, which is provided in the liquefaction chamber and is configured to be connected or not connected with the outside of the cabinet;
[0016] The second air inlet is provided in the liquefaction chamber and is configured to be connected with or not connected with the interior of the storage chamber.
[0017] In the preferred technical solution of the above storage cabinet, the gasification part includes:
[0018] A gasification cavity, which is arranged inside the cabinet;
[0019] a gasification element, which is disposed inside the gasification cavity and is used to gasify the first liquid water or the second liquid water inside the gasification cavity into gaseous water;
[0020] A first gas outlet, which is provided in the gasification cavity and is configured to be connected or disconnected with the interior of the storage cavity;
[0021] The second gas outlet is arranged in the gasification cavity and is configured to be connected with or not connected with the outside of the cabinet.
[0022] In a preferred technical solution of the above storage cabinet, the storage cabinet further comprises a first partition and a second partition, the first partition and the second partition are connected to each other and form the liquefaction cavity and the gasification cavity which are adjacently arranged with the inner wall of the cabinet.
[0023] When the above technical solution is adopted, the liquefaction cavity and the gasification cavity are formed by the first partition and the second partition that are arranged inside the cabinet and connected to each other and the inner wall of the cabinet, so that the humidity control module of the present invention has a simple structure and reduces the cost of the storage cabinet.
[0024] In the preferred technical solution of the above storage cabinet, the vaporizing component and the liquefying component correspond to the hot end and the cold end of the semiconductor refrigeration chip.
[0025] When the above technical solution is adopted, the vaporization component is the hot end of the semiconductor refrigeration chip, and the liquefaction component is the cold end of the semiconductor refrigeration chip, so that the gaseous water in the air inside the liquefaction cavity is liquefied into the first liquid water or the second liquid water through the cold end of the semiconductor refrigeration chip, and the first liquid water or the second liquid water inside the vaporization cavity is vaporized into gaseous water through the hot end of the semiconductor refrigeration chip. Among them, since the liquefaction cavity and the vaporization cavity are connected, the first liquid water or the second liquid water liquefied by the cold end of the semiconductor refrigeration chip can flow into the vaporization cavity, thereby providing the first liquid water or the second liquid water to the hot end of the semiconductor refrigeration chip inside the vaporization cavity. In this way, in the process of humidifying or dehumidifying the storage cavity through the semiconductor refrigeration chip, the cold end of the semiconductor refrigeration chip liquefies the gaseous water in the air inside the liquefaction cavity, and then the hot end of the semiconductor refrigeration chip vaporizes the first liquid water or the second liquid water liquefied by the cold end of the semiconductor refrigeration chip. In the process of working through the semiconductor refrigeration chip, the hot end of the semiconductor refrigeration chip absorbs the heat in the vaporization cavity in the process of vaporizing the first liquid water or the second liquid water, so that the temperature of the vaporization cavity will be reduced accordingly, and then the temperature of the hot end of the semiconductor heating chip will be reduced accordingly, thereby improving the heat dissipation speed of the hot end of the semiconductor refrigeration chip, thereby improving the working efficiency of the semiconductor refrigeration chip.
[0026] In the preferred technical solution of the above storage cabinet, the vaporization part further includes a first fan, which is arranged inside the vaporization cavity and is configured to blow air to the hot end of the semiconductor refrigeration chip.
[0027] In the preferred technical solution of the above storage cabinet, the liquefaction part also includes a second fan, which is arranged inside the liquefaction cavity and is used to blow air to the cold end of the semiconductor refrigeration chip.
[0028] In the preferred technical solution of the above storage cabinet, the liquefaction part further includes a first water collecting box, which is used to receive the first liquid water or the second liquid water liquefied by the liquefaction member;
[0029] The gasification part further includes a second water collecting box, which is connected to the first water collecting box through the connecting part, so that the first liquid water or the second liquid water in the first water collecting box flows into the second water collecting box through the connecting part;
[0030] In the preferred technical solution of the above-mentioned storage cabinet, the storage cabinet also includes a humidity sensor and a controller, and the humidity sensor and the humidity control module are respectively connected to the controller, wherein the humidity sensor is used to detect the humidity of the air inside the storage cavity, so that the controller controls the humidity control module to dehumidify or humidify the storage cavity according to the humidity of the air inside the storage cavity, thereby achieving control of the humidity of the air inside the storage cavity.

[0040] Figure 1 It is a schematic diagram of the three-dimensional structure of a storage cabinet according to an embodiment of the present invention. Figure 2 It is a longitudinal cross-sectional view along the left-right direction at the guide pipe when the storage cabinet is in a humidification working state according to an embodiment of the present invention. Figure 3 It is a longitudinal cross-sectional view along the left-right direction at the guide pipe when the storage cabinet according to one embodiment of the present invention is in a dehumidification working state.
[0041] like Figure 1 See also Figure 2-Figure 3 In order to solve the problem of inconvenience for users in the technical solution of gasifying water in a water tank by a gasification device in an existing storage cabinet with a constant temperature and humidity function, it is usually necessary to manually add liquid water to the water tank. The present invention provides a storage cabinet 100, which includes a cabinet body 1, a cabinet door (not shown), and a storage cavity 2 for storing articles formed inside the cabinet body 1 by the cabinet body 1 and the cabinet door. The storage cabinet 100 also includes a humidity control module 3, which is arranged on the cabinet body 1 and is configured to introduce gaseous water in the air outside the cabinet body 1 into the storage cavity 2 when humidifying the storage cavity 2, and to liquefy and then gasify the gaseous water in the air outside the cabinet body 1 through the humidity control module 3 to increase the air humidity of the air inside the storage cavity 2, and is also configured to liquefy and then gasify the gaseous water in the air inside the storage cavity 2 and discharge it to the outside of the cabinet body 1 when dehumidifying the storage cavity 2, so as to reduce the air humidity of the air inside the storage cavity 2.
[0042] When the storage cavity 2 is humidified by the present invention, the humidity control module 3 introduces the gaseous water outside the cabinet 1 into the storage cavity 2 to humidify the air inside the storage cavity 2. Therefore, when the storage cavity 2 is humidified by the present invention, only the gaseous water outside the cabinet 1 is needed, and there is no need to add liquid water to the storage cavity 2. In this way, there is no need for the user to manually add water to the storage cabinet 100, which makes it more convenient for the user to use the storage cabinet 100.
[0043] Furthermore, when the storage cavity 2 is dehumidified, the humidity control module 3 discharges the gaseous water inside the cabinet 1 to the outside of the cabinet 1, so that when the storage cavity 2 is dehumidified, the humidity control module 3 discharges the gaseous water to the outside of the cabinet 1, and no liquid water is generated inside the storage cavity 2. This reduces the risk of liquid water accumulating inside the storage cavity 2 and breeding bacteria during the dehumidification process.
[0044] In addition, in the process of realizing the present invention, the inventors also found that: in the process of humidification of the storage cabinet 100 in the prior art, if the liquid water in the water storage tank is tap water, scale will form on the surface of the gasification device as the liquid water continues to evaporate. When the amount of scale reaches a certain level, the gasification efficiency of the gasification device will also decrease. Moreover, the scale on the surface of the gasification device will also cause damage to the gasification device. In order to avoid this situation, it is necessary to add pure water to the water storage tank, which increases the humidification cost of the storage cabinet 100.
[0045] The humidity control module 3 of the present invention liquefies the gaseous water in the air outside the cabinet 1 or the gaseous water in the air inside the cabinet 1, and then the humidity control module 3 vaporizes the liquid water liquefied by the humidity control module 3 itself, which saves water resources and does not form scale on the humidity control module 3, thereby ensuring the stability of the humidity control module 3 of the present invention and improving user satisfaction.
[0046] As a possible implementation, Figure 1 See also Figure 2-Figure 3 The humidity control module 3 includes: a liquefaction part 31, a vaporization part 33 and a connecting part 32. The liquefaction part 31 is used to liquefy the gaseous water outside the cabinet 1 into the first liquid water or to liquefy the gaseous water inside the storage cavity 2 into the second liquid water. When the humidity control module 3 humidifies the storage cavity 2, the liquefaction part 31 liquefies the gaseous water in the air outside the cabinet 1 to the liquefaction part 31. When the humidity control module 3 dehumidifies the storage cavity 2, the liquefaction part 31 liquefies the gaseous water in the air inside the storage cavity 2 to the liquefaction part 31. The vaporization part 33 is used to vaporize the first liquid water or the second liquid water. When the humidity control module 3 humidifies the storage cavity 2, the vaporization part 33 vaporizes the first liquid water to the storage cavity 2. When the humidity control module 3 dehumidifies the storage cavity 2, the vaporization part 33 vaporizes the second liquid water to the outside of the cabinet 1. The connecting portion 32 is disposed between the gasification portion 33 and the liquefaction portion 31, and is used to connect the liquefaction portion 31 and the gasification portion 33, so that the liquefaction portion 31 allows the first liquid water or the second liquid water liquefied by the liquefaction portion 31 to flow into the gasification portion 33 through the connecting portion 32, thereby realizing the transfer of the first liquid water or the second liquid water from the liquefaction portion 31 to the gasification portion 33, so that the gasification portion 33 can gasify the first liquid water or the second liquid water.
[0047] As a possible implementation, Figure 1 See also Figure 2-Figure 3 The liquefaction part 31 includes: a liquefaction chamber 311, a liquefaction element 313, a first air inlet 312 and a second air inlet 315. The liquefaction chamber 311 is arranged inside the cabinet 1. The liquefaction element 313 is arranged inside the liquefaction chamber 311, and is used to liquefy the gaseous water in the liquefaction chamber 311 into the first liquid water or the second liquid water. The first air inlet 312 is arranged in the liquefaction chamber 311, and is configured to be connected or not connected with the outside of the cabinet 1. The second air inlet 315 is arranged in the liquefaction chamber 311, and is configured to be connected or not connected with the inside of the storage chamber 2.
[0048] It should be noted that, although the liquefaction part 31 described above in conjunction with the accompanying drawings includes a liquefaction chamber 311, a liquefaction element 313, a first air inlet 312, and a second air inlet 315, this is not restrictive. In other embodiments of the present invention, the liquefaction part 31 may not have a liquefaction chamber 311, and correspondingly, may not have the first air inlet 312 and the second air inlet 315. Instead, it only needs to include a liquefaction element 313, which is mounted on the cabinet 1 in a rotatable manner. For example, the liquefaction element 313 is configured so that when the storage chamber 2 needs to be humidified, the liquefaction element 313 rotates to the outside of the cabinet 1 to liquefy the gaseous water in the air outside the cabinet 1, and when the storage chamber 2 needs to be dehumidified, the liquefaction element 313 rotates to the inside of the storage chamber 2 to liquefy the gaseous water inside the storage chamber 2.
[0049] Alternatively, the liquefaction part 31 can also be constructed to include a first liquefaction component 313 and a second liquefaction component 313. Specifically, the first liquefaction component 313 is constructed to be installed inside the storage cavity 2, and the second liquefaction component 313 is installed outside the cabinet 1. When the storage cavity 2 needs to be humidified, the first liquefaction component 313 does not work, and the second liquefaction component 313 works, and is used to liquefy the gaseous water in the air outside the cabinet 1 through the second liquefaction component 313. When the storage cavity 2 needs to be dehumidified, the first liquefaction component 313 works, and the second liquefaction component 313 does not work, and is used to liquefy the gaseous water inside the storage cavity 2 through the first liquefaction component 313.
[0050] Without departing from the basic principles of the present invention, technicians in this field can flexibly select the specific setting form of the liquefaction part 31 according to the specific application scenario, as long as it can achieve the purpose of liquefying the gaseous water in the air outside the cabinet 1 when humidifying the interior of the storage cavity 2, and liquefying the gaseous water inside the storage cavity 2 when dehumidifying the interior of the storage cavity 2.
[0051] As a possible implementation, Figure 1 See also Figure 2-Figure 3The gasification part 33 includes: a gasification cavity 332, a gasification element 333, a first gas outlet 335 and a second gas outlet 331. The gasification cavity 332 is arranged inside the cabinet 1. The gasification element 333 is arranged inside the gasification cavity 332, and is used to gasify the first liquid water or the second liquid water inside the gasification cavity 332 into gaseous water. The first gas outlet 335 is arranged in the gasification cavity 332, and is configured to be connected or not connected with the inside of the storage cavity 2. The second gas outlet 331 is arranged in the gasification cavity 332, and is configured to be connected or not connected with the outside of the cabinet 1.
[0052] It should be noted that although the vaporization section 33 described in combination with the accompanying drawings includes a vaporization chamber 332, a vaporization component 333, a first air outlet 335 and a second air outlet 331, this is not restrictive. In other embodiments of the present invention, the vaporization section 33 may not have a vaporization chamber 332, and correspondingly, may not have the first air outlet 335 and the second air outlet 331, but only include a vaporization component 333, which is rotatably mounted on the cabinet 1. For example, the vaporization component 333 is configured to rotate to the inside of the storage chamber when it is necessary to humidify the storage chamber 2, and to vaporize the first liquid water into the storage chamber 2; when it is necessary to dehumidify the inside of the storage chamber 2, the vaporization component 333 rotates to the outside of the cabinet 1, and to vaporize the second liquid water to the outside of the cabinet 1.
[0053] Alternatively, the vaporization part 33 may also be constructed to include a first vaporization component 333 and a second vaporization component 333. Specifically, the first vaporization component 333 is constructed to be installed on the outside of the cabinet 1, and the second vaporization component 333 is installed inside the storage cavity 2. When the storage cavity 2 needs to be humidified, the first vaporization component 333 does not work, and the second vaporization component 333 works, and is used to vaporize the first liquid water to the inside of the storage cavity 2 through the second vaporization component 333. When the storage cavity 2 needs to be dehumidified, the first vaporization component 333 works, and the second vaporization component 333 does not work, and is used to vaporize the second liquid water to the outside of the cabinet 1 through the first vaporization component 333.
[0054] Without departing from the basic principles of the present invention, technicians in this field can flexibly select the specific setting form of the vaporization part 33 according to the specific application scenario, as long as it can achieve that when the storage cavity 2 is humidified, the liquid water is vaporized to the inside of the storage cavity 2, and when the storage cavity 2 is dehumidified, the liquid water is vaporized to the outside of the cabinet 1.
[0055] As a possible implementation, Figure 2 See also Figure 3The storage cabinet 100 further includes a first partition 15 and a second partition 16. The first partition 15 is vertically arranged inside the cabinet 1, and the upper end of the first partition 15 is vertically connected to the top wall of the cabinet 1. The second partition 16 is horizontally arranged inside the cabinet 1, and the left and right ends of the second partition 16 abut against the left and right side walls of the cabinet 1, respectively, and the upper surface of the second partition 16 is vertically connected to the lower end of the first partition 15, so that the first partition 15 and the second partition 16 are vertically connected to each other and form a liquefaction cavity 311 and a vaporization cavity 332 arranged adjacent to the inner wall of the cabinet 1.
[0056] It should be noted that although the first partition 15 and the second partition 16 described in combination with the accompanying drawings are vertically connected to each other, this is not restrictive. Obviously, the first partition 15 and the second partition 16 may not be vertically connected to each other, as long as the first partition 15 and the second partition 16 are connected to each other and form a liquefaction cavity 311 and a gasification cavity 332 with the inner wall of the cabinet 1.
[0057] In addition, the liquefaction cavity 311 and the gasification cavity 332 may not be formed by interconnecting the first partition 15 and the second partition 16. Obviously, the liquefaction cavity 311 and the gasification cavity 332 may also be two sealed cavities installed inside the cabinet 1, and the two cavities may be interconnected or independently arranged.
[0058] Without departing from the basic principles of the present invention, those skilled in the art can flexibly select the specific settings of the liquefaction chamber 311 and the vaporization chamber 332 according to the specific application scenario, as long as it can be achieved that when the storage chamber 2 is humidified, the liquefaction chamber 311 is connected to the outside of the cabinet 1 and is not connected to the storage chamber 2, and the vaporization chamber 332 is connected to the storage chamber 2 and is not connected to the outside of the cabinet 1; and when the storage chamber 2 is dehumidified, the liquefaction chamber 311 is not connected to the outside of the cabinet 1 and is connected to the storage chamber 2, and the vaporization chamber 332 is not connected to the storage chamber 2 and is connected to the outside of the cabinet 1.
[0059] As a possible implementation, Figure 2 See also Figure 3, the first air inlet 312 is arranged on the left side wall of the cabinet 1, and the first air inlet 312 is rotatably connected to the first door body 11 through a rotation drive mechanism (not shown) to drive the first door body 11 to rotate relative to the first air inlet 312, so that the first air inlet 312 has an open state and a closed state. Preferably, the rotation drive mechanism is an electric hinge (not shown), so that the first door body 11 is rotatably installed at the first air inlet 312 through the electric hinge (not shown) to realize the opening and closing of the first air inlet 312. The second air inlet 315 is arranged on the second partition 16, and the second air inlet 315 is rotatably connected to the second door body 12 through a rotation drive mechanism (not shown) to drive the second door body 12 to rotate relative to the second air inlet 315, so that the second air inlet 315 has an open state and a closed state. Preferably, the rotation driving mechanism is an electric hinge (not shown), so that the second door body 12 is rotatably installed at the second air inlet 315 through the electric hinge (not shown) to realize the opening and closing of the second air inlet 315.
[0060] As a possible implementation, Figure 2 See also Figure 3 , the first air outlet 335 is arranged on the second partition 16, and the first air outlet 335 is rotatably connected to the third door body 13 through a rotation drive mechanism (not shown) to drive the third door body 13 to rotate relative to the first air outlet 335, so that the first air outlet 335 has an open state and a closed state. Preferably, the rotation drive mechanism is an electric hinge (not shown), so that the third door body 13 is rotatably installed at the first air outlet 335 through an electric hinge (not shown) to realize the opening and closing of the first air outlet 335. The second air outlet 331 is arranged on the right side wall of the cabinet 1, and the second air outlet 331 is rotatably connected to the fourth door body 14 through a rotation drive mechanism (not shown) to drive the fourth door body 14 to rotate relative to the second air outlet 331, so that the second air outlet 331 has an open state and a closed state. Preferably, the rotation driving mechanism is an electric hinge (not shown), so that the second door body 12 is rotatably installed at the second air inlet 315 through the electric hinge (not shown) to realize the opening and closing of the second air inlet 315.
[0061] Of course, in other embodiments, the rotation drive mechanism may also be a common rotation drive mechanism such as a motor drive or a hydraulic drive.
[0062] As a possible implementation, Figure 1 See also Figure 2-Figure 3The vaporization component 333 and the liquefaction component 313 are integrally connected to form a semiconductor refrigeration chip, wherein the vaporization component 333 is the hot end of the semiconductor refrigeration chip, the liquefaction component 313 is the cold end of the semiconductor refrigeration chip, and the semiconductor refrigeration chip is installed on the first partition 15 so that the hot end of the semiconductor refrigeration chip is located inside the vaporization cavity 332, and the cold end of the semiconductor refrigeration chip is located inside the liquefaction cavity 311, and the liquefaction cavity 311 and the vaporization cavity 332 are connected through the connecting part 32. At this time, when the storage cavity 2 needs to be humidified or dehumidified, the semiconductor refrigeration chip is in a working state, so that the cold end of the semiconductor refrigeration chip located inside the liquefaction cavity 311 has a lower temperature, and the hot end of the semiconductor refrigeration chip located inside the vaporization cavity 332 has a higher temperature, so that the cold end of the semiconductor refrigeration chip condenses the gaseous water in the air of the liquid cavity 311 into the first liquid water or the second liquid water, and the hot end of the semiconductor refrigeration chip vaporizes the first liquid water or the second liquid water that flows into the vaporization cavity 332 through the connecting portion 32. In this way, the gaseous water in the liquefaction cavity 311 is transferred to the inside of the storage cavity 2 or the outside of the cabinet 1, so that the humidification and dehumidification of the storage cavity 2 are achieved by controlling the connection state between the liquefaction cavity 311 and the vaporization cavity 332 and the outside of the cabinet 1 and the storage cavity 2.
[0063] Furthermore, during the operation of the semiconductor refrigeration chip, the cold end of the semiconductor refrigeration chip liquefies the gaseous water in the air, and then the hot end of the semiconductor refrigeration chip vaporizes the liquid water liquefied by the cold end of the semiconductor refrigeration chip, so that the gaseous water in the air outside the cabinet 1 is transferred to the storage cavity 2, or the gaseous water inside the storage cavity 2 is transferred to the outside of the cabinet 1, so that the humidification and dehumidification operations of the present invention do not require additional water resources to be added, so as to achieve the technical effect of not requiring the user to manually add water to the storage cabinet 100, so that the user can use the storage cabinet 100 of the present invention more conveniently, thereby improving the user's usage experience.
[0064] In addition, during the operation of the semiconductor refrigeration chip, the hot end of the semiconductor refrigeration chip absorbs the heat in the gasification cavity 332 during the process of gasifying the first liquid water or the second liquid water, so that the temperature of the gasification cavity 332 will be reduced accordingly, which will cause the temperature of the hot end of the semiconductor refrigeration chip to be reduced accordingly. Then, according to the thermoelectric effect of the semiconductor refrigeration chip, the reduction of the hot end temperature of the semiconductor refrigeration chip will cause the temperature of the cold end of the semiconductor refrigeration chip to be further reduced, thereby further improving the working efficiency of the semiconductor refrigeration chip, so that the present invention has higher humidification efficiency and dehumidification efficiency.
[0065] Of course, in other embodiments, the liquefied component 313 can also be a condenser connected to a compressor, used to cool the gaseous water in the air so that the gaseous water in the air is condensed into the first liquid water or the second liquid water. The vaporization component 333 is an evaporator connected to a compressor, used to heat and vaporize the first liquid water or the second liquid water into gaseous water, wherein the compressor can be installed outside the cabinet 1 or inside the cabinet 1. Obviously, the liquefied component 313 can also be other cooling devices with cooling function, and the vaporization component 333 can also be other heating devices with heating function that can accelerate the vaporization of liquid water.
[0066] Alternatively, the liquefied component 313 may also be a dehumidification device with a water absorption function, which absorbs gaseous water in the air into the interior of the dehumidification device, and enables the first liquid water or the second liquid water to seep out from the interior of the dehumidification device under the action of its own gravity. The vaporization part 33 may also be an atomizer with a function of atomizing the first liquid water or the second liquid water. Without departing from the basic principles of the present invention, those skilled in the art may flexibly select the specific setting form of the liquefied component 313 and the vaporization component 333 according to the specific application scenario, as long as the liquefied component 313 can liquefy the gaseous water in the air into the first liquid water or the second liquid water, and transfer the first liquid water or the second liquid water to the vaporization component 333, and then the vaporization component 333 vaporizes the received first liquid water or the second liquid water into gaseous water.
[0067] In addition, in the process of implementing the present invention, the inventors found that the hot end of the semiconductor refrigeration chip and the cold end of the semiconductor refrigeration chip are installed respectively in the adjacent vaporization cavity 332 and the liquefaction cavity 311, so that the vaporization cavity 332 has a lower temperature under the cooling effect of the adjacent liquefaction cavity 311 with a lower temperature, thereby avoiding the high temperature caused by the continuous operation of the hot end of the semiconductor refrigeration chip, thereby further ensuring the working efficiency of the semiconductor refrigeration chip.
[0068] Moreover, in the process of realizing the present invention, the inventors also found that when the hot end of the semiconductor refrigeration chip is set in the vaporization cavity 332, the temperature in the vaporization cavity 332 can be reduced more significantly when liquid water is heated and vaporized in the vaporization cavity 332, compared with directly setting the semiconductor refrigeration chip outside the cabinet 1 or in the storage cavity 2. Therefore, the semiconductor refrigeration chip in the implementation mode of setting the hot end of the semiconductor refrigeration chip in the vaporization cavity 332 has higher working efficiency than the implementation mode of directly setting the semiconductor refrigeration chip outside the cabinet 1 or in the storage cavity 2.
[0069] As a possible embodiment, the vaporization part 33 also includes a first fan (not shown), which is arranged inside the vaporization cavity 332 and is configured to blow air to the hot end of the semiconductor refrigeration chip, so that when the semiconductor refrigeration chip is working, the first fan blows air to the hot end of the semiconductor refrigeration chip, which is used to accelerate the flow speed of the gas on the surface of the semiconductor refrigeration chip, so as to accelerate the heat dissipation speed of the hot end of the semiconductor refrigeration chip, so that the heat is dissipated into the vaporization cavity 332 along the airflow, so as to accelerate the vaporization speed of the liquid water in the vaporization cavity 332, thereby improving the working efficiency of the semiconductor refrigeration chip.
[0070] As a possible implementation, the liquefaction unit 31 further includes a second fan (not shown), which is disposed inside the liquefaction chamber 311 and is configured to blow air to the cold end of the semiconductor refrigeration chip, so that when the semiconductor refrigeration chip is working, the second fan blows air to the cold end of the semiconductor refrigeration chip to accelerate the flow rate of the gas on the cold end surface of the semiconductor refrigeration chip, so as to accelerate the speed of liquefying gaseous water at the cold end of the semiconductor refrigeration chip, so as to improve the efficiency of liquefying gaseous water at the cold end of the semiconductor refrigeration chip. At the same time, by accelerating the flow rate of the gas on the cold end surface of the semiconductor refrigeration chip through the second fan, the risk of frost on the first liquid water or the second liquid water on the cold end surface of the semiconductor refrigeration chip due to too low temperature can also be reduced.
[0071] As a possible implementation, Figure 1 See also Figure 2-Figure 3 The liquefaction part 31 also includes a first water collecting box 314, which is used to receive the first liquid water or the second liquid water liquefied by the liquefier 313. The gasification part 33 also includes a second water collecting box 334, which is connected to the first water collecting box 314 through the connecting part 32, so that the first liquid water or the second liquid water in the first water collecting box 314 flows into the second water collecting box 334 through the connecting part 32. Preferably, the connecting part 32 is a guide pipe 321 provided with a one-way valve, so that the first liquid water or the second liquid water in the first water collecting box 314 flows to the second water collecting box 334 while preventing the liquid water from flowing back, so that the first liquid water or the second liquid water can stably flow into the gasification part 33, and then the gasification part 33 can stably gasify the first liquid water or the second liquid water liquefied by the liquefaction part 31, so as to ensure the stable operation of the humidification or dehumidification work of the storage cabinet 100.
[0072] As a possible implementation, the storage cabinet 100 further includes a humidity sensor and a controller, and the humidity sensor and the humidity control module 3 are connected to the controller respectively. The humidity sensor is arranged inside the storage cavity 2, and is used to detect the humidity of the air inside the storage cavity 2, so that the controller controls the humidity control module 3 to humidify or dehumidify the storage cavity 2 according to the humidity of the air inside the storage cavity 2, thereby realizing the control of the humidity of the air inside the storage cavity 2.
[0073] The working principle of the storage cabinet 100 of the present invention for humidifying and dehumidifying the storage cavity 2 is as follows:
[0074] When the humidity sensor detects that the humidity inside the storage cavity 2 is lower than the lower limit of the preset humidity threshold range, the controller controls the first air inlet 312 to open, the second air inlet 315 to close, the first air outlet 335 to open and the second air outlet 331 to close, so that the liquefaction cavity 311 is connected to the outside of the cabinet 1 and isolated from the storage cavity 2, and at the same time, the vaporization cavity 332 is connected to the storage cavity 2 and isolated from the outside of the cabinet 1, so that the liquefaction component 313 liquefies the gaseous water in the air outside the cabinet 1 into the first liquid water and transfers it to the liquefaction cavity 311, and then allows the first liquid water to flow into the vaporization cavity 332 through the guide tube 321, and finally the vaporization component 333 vaporizes the received first liquid water into the storage cavity 2, thereby humidifying the storage cavity 2.
[0075] When the humidity sensor detects that the humidity inside the storage cavity 2 is higher than the lower limit of the preset humidity threshold range, the controller controls the first air inlet 312 to be closed, the second air inlet 315 to be opened, the first air outlet 335 to be closed, and the second air outlet 331 to be opened, so that the liquefaction cavity 311 is in a connected state with the storage cavity 2 and is isolated from the outside of the cabinet 1, and at the same time, the gasification cavity 332 is isolated from the storage cavity 2 and is in a connected state with the outside of the cabinet 1, so that the liquefaction component 313 liquefies the gaseous water in the air inside the storage cavity 2 into second liquid water and transfers it to the liquefaction cavity 311, and then the second liquid water flows into the gasification cavity 332 through the guide pipe 321, and finally the gasification component 333 vaporizes the received second liquid water to the outside of the cabinet 1, thereby dehumidifying the storage cavity 2. Through the above control method, the humidity of the air inside the storage cavity 2 is within the preset humidity threshold range.
[0076] Furthermore, during the specific implementation of the present invention, the inventors discovered that, in the process of humidifying the storage cavity 2, due to the different humidity of the air outside the cabinet 1, the speed at which the liquefier 313 liquefies the gaseous water will also be different. This makes it possible that when the humidity in the air outside the cabinet 1 is within a normal range, the speed at which the liquefier 313 liquefies the gaseous water is equivalent to the speed at which the vaporizer 333 vaporizes the liquid water. At this time, when the storage cavity 2 is humidified, there is almost no liquid water remaining inside the liquefier 311 and the vaporizer 332, thereby reducing the risk of bacteria growing in the liquefier 311 and the vaporizer 332 due to residual water. However, when the humidity in the air outside the cabinet 1 is higher than the normal range, the speed at which the liquefied part 313 liquefies the gaseous water is greater than the speed at which the gasification part 333 gasifies the liquid water. In this way, when the storage cavity 2 is humidified, the speed at which the liquid water flows into the gasification cavity 332 is greater than the speed at which the liquid water gasifies, so that when the storage cavity 2 is humidified, liquid water will remain inside the gasification cavity 332, and even liquid water will remain in the liquefied cavity 311. Then, in order to avoid the problem of bacterial growth caused by the liquid water remaining inside the gasification cavity 332 and the liquefaction cavity 311. When the storage cavity 2 is humidified, the humidity of the air outside the cabinet 1 can be measured by an external humidity detector arranged outside the cabinet 1. When the humidity of the air outside the cabinet 1 is higher than the normal value, the gasification efficiency of the gasification part 333 is improved, for example, the rotation speed of the fan inside the gasification cavity 332 is increased, or the surface temperature of the gasification part 333 is increased. The speed at which the gasification component 333 gasifies liquid water is greater than or equal to the speed at which the liquefaction component 313 liquefies gaseous water in the air, so that there is no residual first liquid water or second liquid water in the gasification cavity 332 and the liquefaction cavity 311, or the amount of the first liquid water or the second liquid water remaining in the gasification cavity 332 and the liquefaction cavity 311 is less than a residual threshold value, wherein the residual threshold value can be determined according to specific needs, as long as the amount of liquid water remaining in the gasification cavity 332 and the liquefaction cavity 311 is less than the residual threshold value so that bacteria do not grow.
