The embodiment provides a water absorption and dehydration device, which comprises a water absorption and dehydration device 1, a cigarette machine body 2 and a sewage discharge pipe, as shown in figures 1 and 2;

the water absorption and dehydration device 1 comprises a water absorption and dehydration component 11 for absorbing water molecules, a heating element 12 and a water containing box 13;

the water absorbing and dehydrating component 11, the heating component 12 and the water containing box 13 are all arranged on the cigarette machine body 2, and the water absorbing and dehydrating component 11 is communicated with the water containing box 13; the heating element 12 is connected with the water absorption and dehydration component 11 and is used for heating the water absorption and dehydration component 11, so that water molecules adsorbed by the water absorption and dehydration component 11 escape from the water absorption and dehydration component 11 again and are condensed, and then flow into the water containing box 13 and are used for supplying water to the automatic cleaning system of the cigarette machine body 2;

the blow-off pipe is connected with the cigarette machine body 2 and is used for discharging the waste water generated by the automatic cleaning of the cigarette machine body 2.

When the cigarette machine body 2 is in a non-working state, the water absorption and dehydration component 11 absorbs water molecules from the air outside the cigarette machine body 2 and stores the water molecules in the water absorption and dehydration component 11.

When the cigarette machine body 2 is in a working state, the heating component 12 heats the water absorbing and dehydrating component 11, and after the water absorbing and dehydrating component 11 is heated, the adsorbed water molecules escape from the water absorbing and dehydrating component 11 again and are condensed, and finally flow into the water containing box 13; the water in the water containing box 13 can be used for an automatic cleaning system of the cigarette machine body 2, for example, the automatic cleaning function of the cigarette machine body 2 is started, the cigarette machine body 2 pumps the water in the water containing box 13 to the automatic cleaning system, and the automatic cleaning of the cigarette machine body 2 is realized;

because the drain pipe in this embodiment is connected to the cigarette maker body 2, the waste water produced by the automatic washing is finally discharged out of the cigarette maker body 2 along the drain pipe, for example, directly into the sewer of the kitchen of the user.

From the above description, the automatic cleaning range hood of the embodiment has the water absorbing and dehydrating device 1, so that water is not required to be added into the water containing box manually, and the actual use frequency of the automatic cleaning function of the automatic cleaning range hood by a user is improved.

Preferably, the automatic cleaning function of the cigarette machine body 2 can be manually started by a user or automatically started.

In the specific implementation, the water absorbing and dewatering component 11 has the function of actively absorbing water molecules and discharging the absorbed water molecules after being heated.

The water absorbing and dewatering component 11 comprises a shell 111 with a containing cavity and a porous hydrophilic adsorption material 112; the shell 111 is installed on the cigarette machine body 2, the shell 111 is connected with the heating element 12, and the porous hydrophilic adsorption material 112 is filled in the accommodating cavity and used for adsorbing water molecules outside the cigarette machine body 2.

Preferably, the accommodating cavity of the shell 111 is not communicated with the smoke collecting cavity of the cigarette machine body 2, so that oil stains are prevented from blocking the water suction holes 113 and the porous hydrophilic adsorption material 112.

The porous hydrophilic adsorbent material 112 adsorbs water molecules from the air outside the cigarette body 2 and is stored in a porous structure. When the heating element 12 heats the shell 111, the porous hydrophilic adsorption material 112 is indirectly heated, and water molecules adsorbed by the porous hydrophilic adsorption material 112 escape from the porous structure and gradually condense in the accommodating cavity, and finally flow into the water containing box 13.

Preferably, the porous hydrophilic adsorption material 112 has a porous structure, is hydrophilic, and is a material that easily desorbs water molecules.

Preferably, the porous hydrophilic adsorption material 112 is a metal-organic framework material, for example, the porous hydrophilic adsorption material 112 may be MOF-801, where MOF-801 is a combination of zirconium metal and adipic acid, can bind water vapor, and is like a sponge, and has a large internal surface area, which is convenient for adsorbing water molecules and is also convenient for storing water; in addition, the MOF-801 only needs little energy to enable the stored water molecules to escape from the internal porous structure of the MOF-801; for example, when MOF-801 is heated, water molecules inside it can escape from its internal porous structure.

Further, the water absorbing and dehydrating component 11 is also provided with a water absorbing hole 113, the water absorbing hole 113 is communicated with the accommodating cavity, and the water absorbing hole 113 is filled with a porous hydrophilic adsorption material 112; the water suction holes 113 ensure that the porous hydrophilic adsorption material 112 continuously contacts with the outside air of the housing 111 to adsorb water molecules in the air, and support the porous hydrophilic adsorption material 112 to a certain extent to prevent the porous hydrophilic adsorption material 112 from deforming greatly.

Preferably, in order to increase the contact area of the porous hydrophilic adsorption material 112 with the air outside the housing 111, the number of the water suction holes 113 is at least two.

Preferably, a water suction hole 113 is disposed on one side surface of the housing 111, as shown in fig. 2.

Preferably, the cross section of the water suction hole 113 may be circular, oval, or polygonal, for example, the cross section of the water suction hole 113 may be triangular, quadrangular, pentagonal, hexagonal, etc., and the cross section of the water suction hole 113 as shown in fig. 2 may be hexagonal.

Further, the water absorbing and dewatering component 11 is also provided with a water collecting cavity 114 and a water discharging hole 115; the water collecting cavity 114 is communicated with the accommodating cavity and is used for collecting water molecules escaping from the porous hydrophilic adsorption material 112; the water discharge hole 115 communicates with the water containing box 13 for guiding the water condensed and collected in the water collecting chamber 114 into the water containing box 13.

Because the water collecting cavity 114 is communicated with the accommodating cavity, when the heating element 12 heats the porous hydrophilic adsorption material 112, water molecules adsorbed by the porous hydrophilic adsorption material 112 can escape again, and diffuse into the water collecting cavity 114, and condense and collect into water in the water collecting cavity 114; and because the water discharge hole 115 is not only communicated with the water containing box 13, but also communicated with the water collecting chamber 114, the condensed water in the water collecting chamber 114 can flow into the water containing box 13 from the water discharge hole 115, thus realizing dehydration and water collection.

In the embodiment, the heating component 12 is used for heating the water absorbing and dehydrating component 11, so that the water molecules adsorbed by the water absorbing and dehydrating component 11 can escape from the water absorbing and dehydrating component 11 again.

The heating element 12 is installed on the shell 111 of the water absorbing and dehydrating assembly 11, and realizes direct heating of the shell 111, and further realizes indirect heating of the porous hydrophilic adsorption material 112.

The heating temperature of the heating element 12 is 25-60 ℃, so as to ensure that water molecules in the porous hydrophilic adsorption material 112 can escape, and the porous hydrophilic adsorption material 112 cannot be damaged due to heating; meanwhile, the energy consumption can be reduced as much as possible.

Further, the heating member 12 may also be a housing of the range hood. Because the range hood is in the in-process of work, the temperature in the collection petticoat pipe is higher, so can lead to the temperature rise of the casing of range hood, when the temperature rises to above 25 ℃, just can be used as the heating member in this embodiment.

Further, the heating element 12 can also be electrically connected with a control system of the cigarette machine body 2; for example, upon activation of the cigarette maker body 2, the control system of the cigarette maker body 2 controls activation of the heating member 12 to heat the water-absorbing dehydrating unit 11.

Preferably, the heating member 12 may be an electric heating plate, an electric heating film, or the like.

The control system of the cigarette machine body 2 comprises a control unit for controlling the heating element 12 to be started or closed according to the received signals and controlling the automatic cleaning system of the cigarette machine body 2 to be started or closed.

The control unit can be a single chip microcomputer and the like.

In the specific embodiment, in order to avoid the overflow of the water in the water containing box 13 and accurately obtain the water amount in the water containing box 13, the automatic cleaning range hood further comprises a water level detection element, the water level detection element is installed in the water containing box 13, and the water level detection element is electrically connected with the control system of the range hood body 2.

The water level detection element is used for detecting the water quantity in the water containing box 13 in real time and feeding the detection result back to the control system of the cigarette machine body 2 in real time, and when the water level detection element detects that the water quantity in the water containing box 13 reaches the maximum water quantity threshold value, the control system controls the heating component 12 to stop working, the water absorption and dehydration component 11 is stopped to be heated, and the water in the water containing box 13 is prevented from overflowing. Wherein the maximum water volume threshold is a value preset in the control system in advance.

When the water quantity detecting element detects that the water quantity in the water containing box 13 reaches the maximum water quantity threshold value or reaches the automatic cleaning water consumption, the control system controls the automatic cleaning function of the cigarette machine body 2 to be started, and water in the water containing box 13 is pumped out to be used for automatically cleaning the cigarette machine body 2.

Preferably, the water amount detecting member may be a water level detecting sensor.

In the specific embodiment, the automatic cleaning range hood further comprises an oil cup 3, the oil cup 3 is detachably mounted on the range hood body 2, and the drain pipe is communicated with the oil cup 3 and is used for discharging oil drops and waste water collected in the oil cup 3 into a sewer.

In the specific embodiment, the user can manually start the automatic cleaning function of the cigarette machine body 2, and can also automatically start the automatic cleaning function of the cigarette machine body 2 at a specified time by setting the starting time.

The working process of the automatic cleaning range hood of the embodiment is specifically described as follows:

when the cigarette machine body 2 is in a non-working state, for example, in a standby state, because the water suction holes 113 are filled with the porous hydrophilic adsorption material 112 (for example, MOF-801), the water molecules in the air outside the cigarette machine body 2 are adsorbed by the porous hydrophilic adsorption material 112 in the water suction holes 113 and stored in the porous structure of the porous hydrophilic adsorption material 112.

When the cigarette machine body 2 is in a working state, that is, in a state of smoking, the control system (for example, a single chip microcomputer) of the cigarette machine body 2 controls the heating element 12 to start working at the same time to heat the shell 111 connected with the heating element 12 (for example, an electric heating film), so that the porous hydrophilic adsorption material 112 is heated, and after the porous hydrophilic adsorption material 112 is heated, water molecules in the porous hydrophilic adsorption material gradually escape and are diffused in the water collecting cavity 114 to form water vapor; also, because the temperature in the water collection chamber 114 decreases, the water vapor may liquefy to droplets in the water collection chamber 114 and collect in the water collection chamber 114;

since the water discharge hole 115 communicates the water collection chamber 114 with the water containing box 13, the water in the water collection chamber 114 flows into the water containing box 13 through the water discharge hole 115.

Because the water level detection element (such as a water level detection sensor) is installed in the water containing box 13, the water level detection element can detect the water amount in the water containing box 13 in real time and feed the water amount back to the control system of the range hood body 2 in real time, and the control system controls the heating element 12 to be started or closed according to the water amount.

For example, when the amount of water in the water containing box 13 reaches the maximum water amount threshold, the control system of the cigarette maker body 2 will control the heating element 12 to stop working so as to avoid the water in the water containing box 13 from overflowing.

For example, when the water in the water containing box 13 reaches the water consumption for automatic cleaning, the control system of the cigarette machine body 2 controls the automatic cleaning function of the cigarette machine body 2 to start, so that the cigarette machine body 2 is automatically cleaned.

The waste water from the automatic cleaning flows into the oil cup 3 and finally flows along the drain pipe into the sewer of the user's kitchen.
