Description

TECHNICAL FIELD

[0001] The present application relates to the field of dehumidification, in particular to a dehumidification device and a cabinet. BACKGROUND

[0002] The humidity in the plum rain season in Jiangsu and Zhejiang is extremely high. Especially when people are not at home, if the cabinet, which is a closed space, is not ventilated frequently, mold will be produced due to the moisture in the air, causing the cabinet to mildew. Moreover, the humidity will cause the cabinet to deform and crack, affecting the use and service life of the cabinet. In view of this problem, the related technology generally places a desiccant or other water-absorbing material in the cabinet to reduce the humidity of the cabinet, or uses a dehumidifier to reduce the humidity of the environment to avoid mildew in the cabinet. The method of using a desiccant or other water-absorbing material to reduce the humidity of the cabinet may need to replace the desiccant every day or even every half day in the case of high humidity, and is not suitable for people who are traveling or on business, and requires a lot of manpower. The dehumidification method using a dehumidifier has a better dehumidification effect than the desiccant, but the implementation cost is high: if it is always turned on, the energy consumption is high; if the dehumidifier is turned on and off manually, it requires a lot of manpower and cannot qualitatively solve the problem of the cabinet.

[0030] In one embodiment, Figure 1 A dehumidification device 100 is provided, as shown in the drawings. Figure 1 The dehumidification device 100 includes a box body 110, a dehumidification module 120, and a liquid collection module 130. The inner wall of the box body 110 is provided with an opening; the dehumidification module 120 is arranged in the box body 110 and connected to the opening; the dehumidification module 120 includes a sensing unit 121, a driving unit 122, and a refrigeration unit 123 connected in sequence; and the liquid collection module 130 is arranged in the box body 110 and disposed below the dehumidification module 120.

[0031] The opening in the inner wall of the box body 110 can be arranged at a specific position in the inner wall of the box body 110 according to actual needs, and the shape, size, and number of the opening can be adjusted according to specific application scenarios to optimize performance. The dehumidification module 120 is connected to the opening, and the dehumidification module 120 is used to absorb the heat of the air outside the box body 110 to promote the cooling of the air around the dehumidification module 120, and the condensed liquid in the air condenses into water droplets inside the box body 110. The liquid collection module 130 is used to collect the condensed liquid affected by the dehumidification module 120. By arranging the liquid collection module 130 inside the box body 110, it can be ensured that these liquids will not re-evaporate back into the air, and at the same time, it can avoid damage to the devices (wood, electrical components) around the box body 110 caused by the falling of the condensed liquid.

[0032] The sensing unit 121 is configured to measure the environmental parameters of the environment in which the dehumidification module 120 is located, and convert the measured values into electrical signals. The environmental parameters collected by the sensing unit 121 are related to the dehumidification state of the environment in which the dehumidification module 120 is located. The sensing unit 121 can provide one or more of the following parameters: the current environmental humidity level, the amount of liquid in the liquid collection module 130. The sensing unit 121 can obtain the current environmental humidity level through a humidity sensor 1211, and can also determine the liquid level in the liquid collection module 130 through a liquid level sensor to obtain the amount of liquid in the liquid collection module 130, or determine the weight of the liquid in the liquid collection module 130 through a weight sensor to obtain the amount of liquid in the liquid collection module 130.

[0033] One end of the driving unit 122 is connected to the sensing unit 121 and receives the sensing signals output by the sensing unit 121. The other end of the driving unit 122 is connected to the refrigeration unit 123 and outputs driving signals to the refrigeration unit 123 to change the operating state of the refrigeration unit 123. The sensing signals detected by the sensing unit 121 are different, and the signals output to the driving unit 122 are also different.

[0034] The refrigeration unit 123 is configured to promote the effective condensation of liquid in the air. The refrigeration unit 123 is operated in response to the driving signals output by the driving unit 122. Optionally, the refrigeration unit 123 starts operating in response to the first driving signals output by the driving unit 122, and stops operating in response to the second driving signals output by the driving unit 122.

[0035] In this embodiment, the sensing unit 121, the driving unit 122 and the refrigeration unit 123 are connected in sequence. The output signals of the sensing unit 121 change the operating state of the driving unit 122, and the refrigeration unit 123 can start or stop operating under the driving of the driving unit 122. The refrigeration unit 123 starts or stops refrigeration work based on the parameters collected by the sensing unit 121 to achieve automatic refrigeration, which can reduce the energy consumption during dehumidification.

[0036] In some embodiments, the sensing unit 121 includes a humidity sensor 1211, and the inner wall of the box body 110 is provided with a grid, and the humidity sensor 1211 is connected to the grid.

[0037] The inner wall grid of the box body 110 can be set in different shapes, sizes and arrangement modes according to actual needs, and the grid shape can be rectangular, circular or other geometric shapes; the shape, size and arrangement mode of the grid on the box wall are not limited in the embodiment. The air outside and inside the box body 110 can flow through the inner wall grid of the box body 110. Optionally, one or more humidity sensors 1211 can be arranged in the dehumidification unit, and the one or more humidity sensors 1211 are connected to the driving unit 122 at the same time. The number of grids on the inner wall of the box body 110 can correspond to the humidity sensor 1211, and the environmental humidity outside the box body 110 is obtained by setting one or more humidity sensors 1211 at different positions in the box body 110.

[0038] In the embodiment, the humidity sensor 1211 is connected with the grid at the box wall, so that the humidity sensor 1211 can collect the environmental humidity outside the box body 110.

[0039] In some embodiments, the sensing unit 121 includes a liquid level sensor located in the liquid collection module 130. The liquid level sensor is used to detect the height of the collected liquid in the liquid collection module 130. Optionally, one or more liquid level sensors can be arranged in the dehumidification unit, and the one or more liquid level sensors are connected to the driving unit 122 at the same time. The detection accuracy of the sensing unit 121 can be improved by the plurality of liquid level sensors.

[0040] In the embodiment, the liquid collection condition in the liquid collection module 130 can be obtained by arranging the liquid level sensor, so that the operation of the refrigeration unit 123 is changed according to the liquid collection condition in the liquid collection module 130.

[0041] Further, the sensing unit 121 includes a humidity sensor 1211 connected with the grid on the inner wall of the box body 110 and a liquid level sensor located in the liquid collection module 130. The humidity sensor 1211 and the liquid level sensor are connected to the driving unit 122 at the same time, so that the operation of the refrigeration unit 123 is adjusted by the humidity and the liquid level at the same time.

[0042] In some embodiments, the refrigeration unit 123 includes a semiconductor element 1231, the hot end of the semiconductor element 1231 is connected with the outer wall of the box body 110, and the cold end of the semiconductor element 1231 is connected with the inner wall of the box body 110.

[0043] The semiconductor element 1231 in the refrigeration unit 123 comprises an electric couple composed of two different types of semiconductor materials. Optionally, the semiconductor element 1231 comprises one or more pairs of N-type semiconductor and P-type semiconductor, which constitute the electric couple. When the refrigeration element operates, direct current passes through the electric couple composed of N-type semiconductor and P-type semiconductor, and energy transfer occurs at the junction of the N-type semiconductor and the P-type semiconductor, so that one end of the semiconductor element 1231 generates a heating effect, and the other end of the semiconductor element 1231 generates a refrigeration effect. The end generating the heating effect is the hot end of the semiconductor element 1231, and the end generating the refrigeration effect is the cold end of the semiconductor element 1231. The semiconductor element 1231 releases heat through the hot end and absorbs heat through the cold end. Optionally, in order to improve the refrigeration stability of the refrigeration unit 123, a heat sink can also be arranged at the hot end of the semiconductor element 1231 to reduce the heat of the hot end, so as to ensure that the temperature difference between the cold end and the hot end is within the range of relative temperature, and the dehumidification amount of the refrigeration module is kept stable.

[0044] In the embodiment, the hot end of the semiconductor element 1231 is connected to the outer wall of the box body 110, and the cold end of the semiconductor element 1231 is connected to the inner wall of the box body 110, so that the temperature of the air in the box body 110 of the dehumidification device 100 decreases after contacting the cold end and condenses into liquid, thereby achieving the effect of dehumidification. At the same time, the semiconductor element 1231 can make the noise and energy consumption generated during the operation of the refrigeration unit 123 small.

[0045] In some embodiments, the liquid collection module 130 comprises a flow guide assembly 131 and a liquid storage tray 132, and the liquid storage tray 132 is arranged below the liquid outlet of the flow guide assembly 131.

[0046] The flow guide assembly 131 is arranged at a position below the refrigeration module where condensed liquid is likely to be generated. The flow guide assembly 131 comprises one or more inclined flow guide plates and a liquid outlet, so that the condensed liquid can flow along the path formed by the flow guide plates to the liquid outlet. It can be understood that the positions of the flow guide plates in the flow guide assembly 131 can be adjusted according to actual needs to adapt to different installation environments and space limitations.

[0047] The liquid storage tray 132 is used to receive the condensed liquid output from the liquid outlet of the flow guide assembly 131. Optionally, the liquid storage tray 132 is provided with a liquid level sensor. Optionally, the liquid storage tray 132 can also be provided with a drain port.

[0048] In the embodiment, by combining the flow guide assembly 131 and the liquid storage tray 132, the problem of random dripping of condensed liquid during dehumidification can be effectively solved, and the effect of improving the use safety of the dehumidification device 100 is achieved.

[0049] Further, in an embodiment, the flow guide assembly 131 comprises a flow guide plate and a flow guide pipe; the flow guide plate is arranged below the refrigeration unit 123 and the flow guide plate is provided with a liquid discharge port; the flow guide pipe is connected with the liquid discharge port. The flow guide plate can be designed to have a specific angle and shape based on the actual liquid discharge requirement. Alternatively, the flow guide plate can be designed to have a slope with a certain angle to facilitate natural liquid discharge under the action of gravity. Alternatively, the inner wall of the flow guide pipe is smooth to reduce the flow resistance of the condensed liquid and prevent blockage caused by impurity deposition. The connection between the flow guide pipe and the liquid discharge port adopts a sealing design to ensure that the condensed liquid in the liquid collection module 130 does not leak.

[0050] In the embodiment, by arranging the flow guide plate and the flow guide pipe, liquid splashing caused by liquid droplets falling onto the liquid storage tray 132 is avoided, and the use safety of the dehumidification device 100 is further improved.

[0051] Further, in an embodiment, the liquid discharge port is located at the lowest position of the flow guide plate to enable the condensed liquid to flow into the flow guide pipe. By arranging the liquid discharge port at the lowest position of the flow guide plate, the condensed liquid can be completely discharged to the maximum extent, and the possibility of liquid accumulation on the flow guide plate causing corrosion problems or bacterial breeding problems is reduced. At the same time, the liquid discharge efficiency can be improved by gravity.

[0052] In some embodiments, the box body 110 comprises a box cover 111; the box cover 111 is located on the side of the box body 110, and the water level height in the liquid collection module 130 can be observed based on the box cover 111. The box cover 111 can be transparent or translucent. Alternatively, the box body 110 can be connected to the box body 110 through a hinge structure, or the box body 110 can be connected to the box body 110 through a bayonet, a magnetic lock or other locking structure. In the embodiment, the box cover 111 with a side opening cover can facilitate the observation of the water level height in the liquid collection module 130 from the side of the box body 110, and the dehumidification device 100 can be conveniently obtained or adjusted.

[0053] In some embodiments, the box body 110 comprises a clamping groove 112, the end of the clamping groove 112 close to the box cover 111 is higher than the end away from the box cover 111, and the clamping groove 112 is used to fix the liquid collection module 130.

[0054] The clamping groove 112 can be arranged on any one or more sides of the inside of the box body 110. Alternatively, the clamping groove 112 can be arranged along one side or both sides of the inner wall of the box body 110, and the position of the clamping groove 112 in the inner wall of the box body 110 can be arranged according to the actual requirement to adapt to the liquid collection module 130 with different sizes and shapes. Alternatively, the flow guide assembly 131 and the liquid storage tray 132 in the liquid collection module 130 are fixed through the clamping groove 112.

[0055] In this embodiment, the liquid collection module 130 is fixed by setting the card slot 112, so that the end of the liquid collection module 130 close to the box cover 111 is higher than the end away from the box cover 111, reducing the possibility of the liquid collection module 130 tipping over, improving the safety of the dehumidification device 100, and facilitating the taking of the liquid collection module 130.

[0056] The embodiments of the present application will be described and illustrated below through preferred embodiments.

[0057] In one embodiment, the dehumidification device 100 includes a box body 110, a dehumidification module 120, and a liquid collection module 130.

[0058] The dehumidification module 120 is used to condense water vapor in the air, and the liquid collection module 130 is arranged below the dehumidification module 120. Considering that direct dripping of condensed water may damage equipment or devices around the dehumidification module 120, Figure 2 A structural diagram of the box body 110 is provided. As shown in Figure 2 The box body 110 includes a flow guide assembly 131 and a liquid storage tray 132, and the liquid storage tray 132 is arranged below the flow guide assembly 131. By setting the flow guide assembly 131 and the liquid storage tray 132, the condensed water can be collected into a container for unified treatment. Optionally, a liquid level sensor is installed in the liquid storage tray 132, which generates a prompt to remind the user to pour water when the water amount exceeds the preset water amount threshold.

[0059] Since the condensed water may splash when flowing to the water storage box by gravity, affecting the normal use of the dehumidification device 100, a flow guide plate is arranged in the flow guide assembly 131, and the flow guide plate has a drainage port connected with a flow guide pipe. The condensed water can flow into the liquid storage tray 132 along the flow guide plate through the flow guide pipe, without splashing to the clothes or other places. The flow guide pipe can be a hose.

[0060] Figure 3 An assembly diagram of the dehumidification box is provided, as shown in Figure 3As shown, the box body 110 further comprises a box cover 111 arranged on the side of the box body 110. In view of aesthetics and practicability, the above-mentioned components are installed in a box with transparent door and openable door, so that the current water amount can be directly observed from outside to prevent partial accumulation of excessive moisture, and the box body can also prevent re-evaporation and diffusion of condensed water to affect the humidity in the cabinet. Optionally, the box body 110 can be designed to be inclined, so that the opening of the box body 110 is not perpendicular to the ground or the bottom surface of the box body 110, but is inclined at a certain angle. Optionally, the box cover 111 is larger than the shape of the box body 110, i.e., the size or unfolded area of the box cover 111 of the box body 110 in the open state exceeds the projection area of the box body 110 itself, thereby facilitating the user to take the liquid collection module 130 and the dehumidification module 120, and also playing a role in aesthetics, avoiding the exposure of the liquid collection module 130 and the dehumidification module 120.

[0061] The box body 110 further comprises a clamping groove 112. The flow guide assembly 131 comprises a flow guide plate, a flow guide pipe and a liquid storage tray 132. Optionally, the flow guide plate is fixed by a single clamping groove 112, which is easier to maintain than a double clamping groove 112 holding the flow guide plate, and is easy to clean when not used for a long time in winter. Optionally, considering that the box body 110 may be inclined when placed, and the placement position of the box body 110 may also be uneven, the clamping groove 112 is arranged inwardly inclined downward by 3 degrees to avoid the flow guide plate sliding forward or even falling off when the cabinet or the dehumidification box body is inclined forward. It can be understood that the angle of the inwardly inclined clamping groove 112 can be modified according to requirements.

[0062] The refrigeration unit 123 in the dehumidification module 120 comprises a semiconductor element 1231. The inner wall of the box body 110 is provided with an opening; the semiconductor element 1231 is fixed on the box body 110 and connected with the opening. By fixing the semiconductor element 1231 in the box body 110, the heat dissipation surface of the semiconductor can be avoided from directly affecting the cabinet 200 body. The dehumidification module 120 further comprises a sensing unit 121. The sensing unit 121 comprises a liquid sensor in the liquid storage tray 132 and a humidity sensor 1211. The humidity sensor 1211 is installed at a position away from the semiconductor element 1231, and a grid hole is provided in the box wall near the sensor, so that the sensor can accurately detect the humidity outside the dehumidification box. The sensing unit 121 is connected with the driving unit 122 of the semiconductor element 1231. Figure 4 For a running schematic diagram of the semiconductor element 1231 in an embodiment, as shown in Figure 4As shown, the semiconductor element 1231 is powered on to start the dehumidification box, and the humidity sensor 1211 acquires the ambient humidity S. When the humidity S is less than or equal to the humidity threshold S0, the semiconductor element 1231 stops running, and the stop duration is T. After the semiconductor element 1231 stops running for the time T, the step of acquiring the ambient humidity S by the temperature sensor can be performed again. When the humidity S is greater than the humidity threshold S0, the liquid level sensor acquires the water amount L in the liquid storage tray 132. The water amount L is compared with the water amount threshold L0. When the water amount L is less than or equal to the water amount threshold L0, the semiconductor element 1231 stops running, and the stop duration is T. After the semiconductor element 1231 stops running for the time T, the step of comparing the water amount L with the water amount threshold L0 can be performed again. When the water amount L is greater than the water amount threshold L0, the user is reminded of the water amount condition in the liquid storage tray 132.

[0063] The dehumidification device 100 in the embodiment automatically performs or stops performing the dehumidification function to avoid unnecessary power consumption; and all components of the dehumidification device 100 are easy to install, disassemble, maintain, and manage.

[0064] The embodiment also provides a cabinet 200. The cabinet 200 in the embodiment is used to implement the above-described embodiments and preferred embodiments, and will not be described again. As used below, the terms "module", "unit", "sub-unit", and the like can be a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, hardware, or a combination of software and hardware can also be implemented and conceived.

[0065] Figure 5 is a structural block diagram of the cabinet 200 in the embodiment of the application, as Figure 5 As shown, the cabinet 200 is provided with the dehumidification device 100. The dehumidification device 100 includes a box body 110, a dehumidification module 120, and a liquid collection module 130. The inner wall of the box body 110 is provided with an opening. The dehumidification module 120 is arranged in the box body 110 and connected with the opening. The dehumidification module 120 includes a sensing unit 121, a driving unit 122, and a refrigeration unit 123 connected in sequence. The liquid collection module 130 is arranged in the box body 110 and disposed below the dehumidification module 120.

[0066] The main reason for the mildew deformation of the cabinet 200 is that the air humidity in the cabinet is too high, and the board is in contact with the moisture in the air for a long time. Because the cabinet 200 is basically a closed box space when it is not opened, the internal air is basically not in communication with the external environment, in order to achieve dehumidification, only the internal space humidity needs to be reduced. In this embodiment, the refrigeration unit 123 can effectively reduce the water vapor content in the air and achieve the effect of effectively dehumidifying the cabinet 200. At the same time, considering that a large piece of cold condensate water will have a great impact on the service life of the board if it is allowed to drop in the cabinet 200, by setting the liquid collection module 130, the deformation of the cabinet 200 board can be avoided.

[0067] Based on the dehumidification box in this embodiment, the cabinet 200 does not need to be modified, and the dehumidification effect of the cabinet 200 can be enhanced without occupying much space. The dehumidification device 100 can be automatically turned on without manual dehumidification, which reduces the cost, noise and manpower.

[0068] In some embodiments, the sensing unit 121 includes a humidity sensor 1211 and / or a liquid level sensor. When the sensing unit 121 includes a humidity sensor 1211, the inner wall of the box body 110 is provided with a grid, and the humidity sensor 1211 is connected with the grid. When the sensing unit 121 includes a liquid level sensor, the liquid level sensor is located in the liquid collection module 130.

[0069] When the humidity is high, the dehumidification device 100 is automatically turned on without manual dehumidification, and the device is automatically turned off when it is not needed, reducing power consumption. Optionally, the liquid level sensor has a prompt unit, and when the water exceeds the preset value, the user can be reminded to pour out the water through the prompt unit.
