Description

Technical Field

[0001] This application relates to the technical field of dehumidification, and particularly to a dehumidification device and a dishwasher. Background Art

[0002] Dishwashers have facilitated people's lives, but many dishwashers cannot completely dry the tableware after the washing program is completed. After the undried tableware is placed for a period of time, a small amount of residual sewage will generate an unpleasant smell in the dishwasher and even breed harmful microorganisms. When the user opens the dishwasher to pick up the tableware, an unpleasant smell will be generated, resulting in a poor user experience and affecting the user's health and mood.

[0003] Currently, there are two ways to remove water vapor in the market. One is to directly exhaust the water vapor, and the other is internal circulation. Zeolite is added to the dishwasher. The zeolite absorbs the water vapor, and then the zeolite is heated to slowly exhaust the absorbed moisture; since the moisture content of the direct exhaust is relatively large, especially in the first ten minutes, this will cause the cabinet to become damp and moldy, and the fog of the moisture exhaust also makes the user experience bad. Especially in winter, a pool of water will condense on the kitchen tiles, which may cause the user to slip; the internal circulation zeolite absorbs moisture, and the amount of moisture absorption is limited, and when the zeolite is desorbed, it needs to be heated to one hundred or even two hundred degrees Celsius, which greatly increases the energy consumption.

[0004] Therefore, in order to solve the above technical problems, an improved dehumidification device is needed. Summary of the Utility Model

[0027] The embodiments will be described below with reference to the drawings, which do not limit the content of the application recorded in the claims in any way.

[0028] In the description of the embodiments of this application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. are all based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0029] Please refer to Figures 1-7 As shown, the embodiment of this application provides a dehumidification device, which includes a housing 1, a dehumidification structure 2 and an exhaust driving device; an air inlet passage 11 and an exhaust passage 12 are arranged in the inner cavity of the housing 1; the dehumidification structure 2 includes a connecting member 21 having a communication cavity and a support member 22 arranged in the communication cavity; one end of the communication cavity is communicated with the air inlet passage 11, and the other end of the communication cavity is communicated with the exhaust passage 12; the support member 22 is used to mount a dehumidification functional member having the function of adsorbing water vapor; the exhaust driving device can form a negative pressure in the inner cavity of the housing 1, and thus can suck steam from the air inlet passage 11, pass through the dehumidification functional member in the communication cavity and be discharged through the exhaust passage 12.

[0030] Specifically, the dehumidification functional member can be MOF powder, which is a porous crystalline material formed by connecting metal ions or clusters with organic ligands through coordination bonds to form a three-dimensional network structure, and has the characteristics of high specific surface area, high porosity and structural designability, so it can be used to adsorb more water vapor.

[0031] Specifically, the connection method between the MOF powder and the support member 22 can be to bond the MOF powder on the support member 22 through an organic adhesive, and improve the bonding force between the MOF powder and the support member by sintering, so as to ensure the connection stability between the MOF powder and the support member 22.

[0032] In the embodiment of the present application, a dehumidification structure is provided, and the air intake passage 11 is connected with the exhaust passage 12 through a connecting piece. Under the drive of the exhaust drive device, water vapor can be sucked in from the air intake passage 11, and discharged through the exhaust passage 12 after passing through the dehumidification functional parts in the connecting cavity. Then, the moisture in the water vapor can be removed through the dehumidification functional parts in the dehumidification structure, and the dried gas can be discharged. The dehumidification device has the advantages of simple structure, low cost, and low energy consumption.

[0033] Reference Figure 7 As shown, in some embodiments, the cross-section of the support member 22 is a honeycomb structure, and the dehumidification functional components are installed in each honeycomb hole 221.

[0034] Furthermore, the diameter of the honeycomb hole 221 is 3 mm to 6 mm, and preferably the diameter of the honeycomb hole 221 is 5 mm.

[0035] Specifically, the connecting member 21 includes a first connecting port 211 and a second connecting port 212 connected to the connecting cavity, the first connecting port 211 is connected to the steam inlet channel 11, and the second connecting port 212 is connected to the exhaust channel 12; the support member 22 is arranged between the first connecting port 211 and the second connecting port 212 in the connecting cavity.

[0036] Specifically, the support member 22 may be made of glass fiber material, and the use of honeycomb glass fiber to load MOF can achieve the goal of loading more MOF materials in a smaller space, exposing more small pores on the surface of the MOF and absorbing more water vapor.

[0037] It should be noted that the adsorption of water by MOF is usually a physical process. During the adsorption process, water molecules first enter the pores and form hydrogen bonds with unsaturated metal sites. Then, these water molecules act as nucleation sites and continue to form hydrogen bonds with other water molecules until the pores of the MOF structure are filled with water molecules. When the relative humidity is high, MOF will also adsorb through capillary action. This water adsorption through pore filling is usually reversible. In other words, compared with other porous materials such as zeolites, the desorption of MOF is significantly easier.

[0038] In the embodiment of the present application, by setting the cross-section of the support member 22 to a honeycomb structure and installing the dehumidification functional component in the honeycomb hole 221, the contact area between the water vapor and the dehumidification functional component is increased, thereby improving the dehumidification effect of the dehumidification structure 2.

[0041] Specifically, the driving device installation cavity 13 is arranged between the exhaust passage 12 and the connection cavity, one end of the driving device installation cavity 13 is communicated with the exhaust passage 12, and the other end of the driving device installation cavity 13 is communicated with the connection cavity.

[0042] Specifically, the exhaust driving device can be an exhaust pump. The intake end of the exhaust pump is communicated with the intake passage 11, and the exhaust end of the exhaust pump is communicated with the exhaust passage 12.

[0043] Specifically, the exhaust pump is accommodated in the driving device installation cavity 13, and the installation fixing part 14 is fixedly connected to the housing 1 through a fastener, and then the installation fixing part 14 is buckled and connected to the driving device installation cavity 13, ensuring the stability of the installation of the exhaust pump and the housing.

[0044] In the embodiment of the present application, by starting the exhaust pump, a negative pressure can be generated at the intake end of the exhaust pump. Then, water vapor can enter from the intake passage 11, pass through the dehumidification function part in the connection cavity, and the dehumidified gas can be discharged from the exhaust passage 12 through the exhaust end of the exhaust pump.

[0045] In some embodiments, the exhaust passage 12 is a curved passage.

[0046] In the embodiment of the present application, the exhaust passage 12 is designed as a curved passage, so as to increase the flow time of the gas in the exhaust passage 12 and further reduce the temperature of the gas.

[0047] In some embodiments, the housing 1 includes an upper housing 15 and a lower housing 16; the upper housing 15 and the lower housing 16 are detachably connected.

[0050] Specifically, both the upper housing 15 and the lower housing 16 can be made of rigid plastic material.

[0051] In the embodiment of the present application, by setting the housing 1 as a detachable upper housing 15 and lower housing 16, it is convenient for the installation and debugging of the exhaust pump.

[0052] In other embodiments, the dehumidification structure 2 can also be detachably installed on the side of the lower shell 16 facing away from the upper shell 15, so that the dehumidification structure 2 can be replaced in time according to specific usage conditions to ensure the dehumidification effect of the dehumidification structure 2.

[0054] Specifically, a plurality of card interfaces are provided on the line support 161 for card connection with the connection line of the exhaust pump to ensure neatness of the wiring of the connection line.
