The dehumidifying apparatus 100 has a plurality of side walls constituting a housing 110, and a dehumidifying passage 101, an auxiliary passage 102, an air supply passage 103, a dehumidifying part, and a first switching part 140 are provided in the housing 110, and an air inlet 104 formed as an inflow passage of a gaseous medium and an air outlet 105 formed as an outflow passage of the gaseous medium are provided in the side walls of the housing 110. That is, the air inlet 104 allows a gaseous medium (such as air or other mixed media with additives, which will be described below as an example of air) from outside the dehumidifying apparatus 100, either indoors or outdoors, to enter the dehumidifying apparatus 100; the air outlet 105 discharges air in the dehumidifying apparatus 100 to the outside of the dehumidifying apparatus 100.

An inlet of the air supply passage 103 is arranged opposite to the air inlet 104, and a first passage partition plate 120 for partitioning the air supply passage 103 and the auxiliary passage 102 is arranged between the air supply passage 103 and the auxiliary passage 102; a second channel partition plate 130 that separates the auxiliary channel 102 and the dehumidification channel 101 is provided between the auxiliary channel 102 and the dehumidification channel 101 so that the air supply channel 103, the auxiliary channel 102, and the dehumidification channel 101 are arranged at intervals in order from the side close to the air inlet 104 to the side away from the air inlet 104, and are independent of each other. The dehumidification channel 101 and the auxiliary channel 102 are turned on in the first operation mode, and the air supply channel 103 is turned on in the second operation mode, that is, in the first operation mode, air flows in from the air inlet 104, is split by the dehumidification channel 101 and the auxiliary channel 102, merges at the upstream side of the air outlet 105, and flows out from the air outlet 105; in the second mode of operation, air flows in from the air inlet 104, through the air supply duct 103, and out the air outlet 105.

The first switching part 140 includes a wind deflector 141 formed in a flat plate shape and a rotation shaft 142 provided at one end of the wind deflector 141 to rotate the wind deflector 141. The air deflector 141 has two working positions, and the air direction of the air inlet 104 is switched between the dehumidification channel 101 and the auxiliary channel 102 and the air supply channel 103 by rotating the air deflector 141 around the rotating shaft 142, so that the dehumidification channel 101 and the auxiliary channel 102 are opened and the air supply channel 103 is closed at the same time; or the dehumidifying passage 101 and the auxiliary passage 102 are closed and the air supply passage 103 is opened at the same time.

Specifically, as shown in fig. 2, in one application scenario, the dehumidifying apparatus 100 is in communication with the heating apparatus 200, the air needs to be dehumidified by the dehumidifying apparatus 100 before entering the heating apparatus 200, the dehumidifying apparatus 100 enters the first operation mode, the dehumidifying apparatus 100 opens the dehumidifying channel 101 and the auxiliary channel 102 by the action of the first switching portion 140, that is, the first switching portion 140 rotates to fully open the dehumidifying channel 101 and the auxiliary channel 102 and closes the air supply channel 103, the air flows into the dehumidifying channel 101 and the auxiliary channel 102 and merges at the upstream side of the air outlet 105, and flows out from the air outlet 105.

Wherein the dehumidifying part is provided in the dehumidifying passage 101, which may include an evaporator 150, a condenser 160 and a compressor 170, a heat medium circulates among the evaporator 150, the condenser 160 and the compressor 170, and the heat medium may be understood as a compound having thermal stability and chemical stability, which may be used for heat transfer, for example, a liquid or gas which transfers heat. The evaporator 150 absorbs ambient latent heat by evaporating the heat medium to condense water vapor in ambient air and generate condensed water; the condenser 160 is provided at a downstream side of the evaporator 150, and heats air passing through the evaporator 150 by condensing the heat medium to release latent heat to the surroundings; the compressor 170 serves to compress a heat medium and communicates with the evaporator 150 and the condenser 160.

Specifically, the air entering the dehumidifying apparatus 100 from the air inlet 104 may exchange heat with the heat medium flowing in the dehumidifying apparatus 100, thereby achieving the purpose of dehumidification. The air passes through the evaporator 150 and exchanges heat with the heat medium in the evaporator 150 to reduce the temperature, and condensed water is released; then, the refrigerant passes through the condenser 160 and exchanges heat with the heat medium in the condenser 160 to raise the temperature, and the refrigeration cycle using the heat medium circulation is a common dehumidification technology in the prior art, and will not be described herein.

Of course, the dehumidifying part may be a member formed by mounting a material having water absorbability such as zeolite or silica gel on a honeycomb-like ceramic paper or the like as a base material, and the like, as long as the moisture in the air can be removed and the air humidity can be reduced.

In the first operation mode, since the split air, that is, a part of the air flows through the auxiliary passage 102, the air flowing through the dehumidifying passage 101 is reduced, the wind speed in the dehumidifying passage 101 is reduced, and the time for heat exchange with the heat medium in the dehumidifying part is increased, thereby improving the dehumidifying effect. Meanwhile, the dehumidification channel 101 and the auxiliary channel 102 are independent from each other due to the action of the second channel separation plate 130, that is, air passing through the auxiliary channel 102 does not pass through the dehumidification channel 101, so that air in the auxiliary channel 102 is not blocked by the dehumidification part and is reduced in wind resistance, and can smoothly reach the air outlet 105, and the air outlet volume of the air outlet 105 is improved. That is, the amount of air flowing into the heating appliance 200 can be increased. In practical application, the amount of air flowing through the dehumidifying part can be adjusted by adjusting the specific sizes of the dehumidifying channel 101 and the auxiliary channel 102 according to the required dehumidifying amount, so that the heating effect can be ensured, and the dehumidifying effect can be improved.

Moreover, since the inlet of the air supply channel 103 is opposite to the air inlet 104, the air supply channel 103, the auxiliary channel 102 and the dehumidifying channel 101 are sequentially arranged at intervals from the side close to the air inlet 104 to the side far away from the air inlet 104, that is, the inlets of the auxiliary channel 102 and the dehumidifying channel 101 are far away from the air inlet 104 compared with the inlet of the air supply channel 103, and after the air enters the housing 110 from the inlet, the air needs to be converted into a certain direction to enter the inlets of the auxiliary channel 102 and the dehumidifying channel 101, so that the air speed flowing into the dehumidifying channel 101 is further reduced, the time for heat exchange with the heat medium in the dehumidifying part is increased, and the dehumidifying effect is further improved.

It should be noted that, the dehumidifying part is only disposed in the dehumidifying channel 101, and the auxiliary channel 102 which is opened simultaneously with the dehumidifying channel 101 is not provided with a corresponding dehumidifying part, so that the problem that the heating effect is poor due to the pressure loss increase caused by the fact that the dehumidifying part blocks the air passage is avoided. Further, the condition that the air outlet is required to be ensured by increasing the air quantity in order to ensure the heating effect is avoided.

As shown in fig. 3, in one application scenario, it is not necessary to dehumidify by using the dehumidifying apparatus 100, the dehumidifying apparatus 100 enters the second operation mode, the dehumidifying apparatus 100 opens the air supply channel 103 by using the action of the first switching part 140, that is, the first switching part 140 rotates to a position of completely opening the air supply channel 103 and closes the dehumidifying channel 101 and the auxiliary channel 102, and air directly flows out of the air outlet 105 after passing through the air supply channel 103 without passing through the dehumidifying part. Since the air inlet 104 is disposed opposite to the inlet of the air supply duct 103, air can smoothly flow from the air inlet 104 to the inlet of the air supply duct 103 without changing the direction, pressure loss is suppressed, and the amount of air flowing into the air supply duct 103 in this application scenario is ensured, thereby ensuring a preferable heating effect.

In addition, regarding the arrangement of the first switching portion, the following two separate embodiments are exemplified.

First embodiment

As shown in fig. 2 and 3, the first switching part 140 is movably disposed at the downstream side of the air inlet 104 and at the upstream side of the inlets of the air supply passage 103, the auxiliary passage 102 and the dehumidifying passage 101 to switch the circulation passage of air between the air supply passage 103 and the auxiliary passage 102 and the dehumidifying passage 101. Further, it is possible to make the end of the first channel separation plate 120 near the air inlet 104 more distant from the side wall where the air inlet 104 is located than the end of the second channel separation plate 130 near the air inlet 104, for example, make the distance D1 between the end of the first channel separation plate 120 near the air inlet 104 and the side wall where the air inlet 104 is located equal to the cross-sectional width D2 of the inlet of the air supply channel 103, and the width of the air deflector 141 be at least greater than D1 and D2, so as to satisfy the opening and closing of the flow channel, and the rotating shaft 142 is provided at the end of the first channel separation plate 120 near the side wall where the air inlet 104 is located. In this way, in the first operation mode, the air deflector 141 may rotate about the rotation shaft 142 to the inlet of the air supply duct 103 to shield the inlet of the air supply duct 103, and air flows into the housing 110 from the air inlet 104 and then flows into the dehumidification duct 101 and the auxiliary duct 102; in the second working mode, the first switching part 140 may also rotate to a position between the first channel separation plate 120 and the sidewall where the air inlet 104 is located, where the position between the first channel separation plate 120 and the sidewall where the air inlet 104 is located is covered, that is, the first channel separation plate 120 and the air deflector 141 of the first switching part jointly separate the air supply channel 103 and the auxiliary channel 102, and after the air flows into the housing 110 from the air inlet 104, the air is blocked by the first channel separation plate 120 and the air deflector 141 of the first switching part, and cannot flow to the dehumidification channel 101 and the auxiliary channel 102, but only flows to the air supply channel 103. Since the distance D1 between the first channel separation plate 120 and the sidewall of the air inlet 104 is longer, a space is provided for the first switching part to be disposed and rotated, so the first switching part can be disposed closer to the inner side of the housing 110, thereby reducing the size of the housing 110 and facilitating the installation of the dehumidifying apparatus 100.

Second embodiment

Fig. 4 is a schematic structural view of a second embodiment of a dehumidifying apparatus 100' according to the present utility model. Fig. 4 shows a schematic view of the dehumidification apparatus 100' provided by the present disclosure in a first operation mode. As shown in fig. 4, the first switching part 140 'is movably disposed at the downstream side of the outlets of the air supply duct 103, the auxiliary duct 102 and the dehumidifying duct 101 and at the upstream side of the air outlet 105, and the rotating shaft 142' is disposed at the end of the first duct partition 120 near the sidewall of the air outlet 105. Further, the other end of the first channel separation plate 120 near the air outlet 105 may be disposed further away from the sidewall where the air outlet 105 is located than the other end of the second channel separation plate 130 near the air outlet 105, for example, the distance D3 between the other end of the first channel separation plate 120 near the air outlet 105 and the sidewall where the air outlet 105 is located is equal to the cross-sectional width D4 of the outlet of the air supply channel 103, and the width of the air deflector 141 'is at least greater than D3 and D4, so as to satisfy the opening and closing of the flow channel, and the rotating shaft 142' is disposed at the end of the first channel separation plate 120 near the sidewall where the air outlet 105 is located, so as to realize the switching of the flow channel of air between the air supply channel 103, the auxiliary channel 102 and the dehumidifying channel 101. In this way, in the first operation mode, the air deflector 141 'may rotate about the rotation shaft 142' to the outlet of the air supply duct 103 to shield the outlet of the air supply duct 103, and after the air flows into the housing 110 from the air inlet 104, the outlet of the air supply duct 103 is closed, so that the air flows into the dehumidification duct 101 and the auxiliary duct 102; in the second working mode, the first switching part 140 'may also rotate to a position between the side walls of the first channel separation plate 120 and the air outlet 105, where the side walls of the first channel separation plate 120 and the air outlet 105 are located, that is, the air supply channel 103 and the auxiliary channel 102 are separated by the first channel separation plate 120 and the air deflector 141' of the first switching part together, and after the air flows into the housing 110 from the air inlet 104, the outlets of the dehumidifying channel 101 and the auxiliary channel 102 are closed, so that the air flows to the air supply channel 103. Since the distance D3 between the first channel separation plate 120 and the sidewall where the air outlet 105 is located is longer, a space is provided for the arrangement and rotation of the first switching part 140', so the first switching part 140' can be arranged closer to the inner side of the housing 110, thereby reducing the size of the housing 110 and facilitating the installation of the dehumidifying apparatus 100.

The first switching unit 140' is provided in the above manner, and the following describes an embodiment in which the dehumidifying apparatus 100 is connected to another apparatus to form the air conditioning apparatus 1000.

FIG. 5 is a schematic diagram showing an assembly relationship of an air conditioning apparatus 1000 according to the present utility model; the connection arrangement of the dehumidification apparatus 100' and the heating apparatus 200 is mainly shown.

As shown in fig. 5, the air conditioning apparatus 1000 is configured by disposing the dehumidifying apparatus 100' on the upstream side of the heating apparatus 200. In the present embodiment, the air inlet 104 of the dehumidifying apparatus communicates with the room through a pipe.

The heating apparatus 200 includes a frame 210, an air inlet 201, a first air supply part 220, a second air supply part 230 and a heating part which are arranged in the frame 210, and an air outlet and a ventilation opening 204 which are arranged on the side wall of the frame 210. The air inlet 201 of the heating apparatus communicates with the air outlet 105 of the dehumidifying apparatus so that air blown out of the dehumidifying apparatus 100' can enter the heating apparatus 200. The air outlet of the heating apparatus 200 may be provided with two or more than two, such as the first heating air outlet 202 and the second heating air outlet 203 shown in fig. 5, and the first heating air outlet 202 and the second heating air outlet 203 communicate with the room so that the air in the heating apparatus 200 enters the room. The heating part of the heating apparatus 200 may include a first heating part 240 and a second heating part 250, such as PTC heaters, respectively provided at the upstream sides of the first heating air port 202 and the second heating air port 203 for heating the air discharged to the front of the room, corresponding to the number of air outlets of the heating apparatus 200.

The two air supply parts are respectively arranged corresponding to the first heating air port 202 and the second heating air port 203, and the first air supply part 220 is arranged on the downstream side of the air inlet 201 and the upstream side of the first heating part 240; the second air blowing unit 230 is disposed on the downstream side of the air intake 201 and on the upstream side of the second heating unit 250. The first air supply part 220 and the second air supply part 230 each include an air supply fan and an air supply snail shell accommodating the air supply fan. The air supply fan comprises an air supply fan and an air supply motor connected with the air supply fan to drive the air supply fan to rotate. The blower fan is, for example, a multi-wing centrifugal fan. The first air supply part 220 provides air to enter the air inlet 104 of the dehumidification device from the indoor through the rotation of the air supply fan, enters the air inlet 201 of the heating device after passing through the dehumidification device 100', and flows out of the first heating air inlet 202, namely the first air supply part 220 pumps the indoor air into the dehumidification device 100', sends the indoor air to the heating device 200, and then sends the air in the heating device 200 to the indoor or outdoor; the second air supply part 230 provides air from the indoor air inlet 104 of the dehumidifying device, the air inlet 201 of the heating device after passing through the dehumidifying device 100', and the power flowing out of the second heating air inlet 203 through the rotation of the air supply fan, namely the second air supply part 230 pumps the indoor air into the dehumidifying device 100', sends the indoor air into the heating device 200, and sends the air in the heating device 200 to the indoor or outdoor.

In one application scenario, the first heating air port 202 and the second heating air port 203 may also be respectively communicated with different indoor spaces, so that the air conditioning device 1000 may provide heated or dehumidified air to a plurality of rooms.

The ventilation port 204 communicates with the outside to allow air in the heating apparatus 200 to be discharged to the outside, and to provide the air conditioning apparatus 1000 with a ventilation function, for example, as shown in fig. 5, the ventilation port 204 may be provided beside the second heating port 203. In the case that the ventilation port 204 is provided beside the second heating air port 203, the heating apparatus 200 may further be provided with a second switching portion having a rotation shaft and rotating about the rotation shaft as a fulcrum. The ventilation port 204 and the second heating air port 203 are provided on the downstream side of the second switching portion, and the second air blowing portion 230 selectively communicates with the ventilation port 204, or communicates with the second heating air port 203, or communicates with both the ventilation port 204 and the second heating air port 203 by rotation of the second switching portion. Namely, the air conditioning apparatus 1000 can realize a heating function, a dehumidifying function, and an exhausting function.

In addition, a part of the dehumidifying apparatus 100 'is embedded in the interior of the heating apparatus 200, for example, the air outlet 105 of the dehumidifying apparatus and the first switching part 140' are located in the interior of the heating apparatus 200, at this time, the air outlet 105 of the dehumidifying apparatus is formed as the air inlet 201 of the heating apparatus, the housing 110 of the dehumidifying apparatus and the frame 210 of the heating apparatus can be coupled together by screws or the like, and the coupling position can be prevented from leaking air by sticking a sponge or the like. Thus, the overall size of the connection between the dehumidifying apparatus 100' and the heating apparatus 200 can be reduced, the air-conditioning apparatus 1000 can be miniaturized, and the installation convenience can be improved.

With the above-described structure, the air conditioning apparatus 1000 can realize at least the first operation mode and the second operation mode, that is, the heating mode in which the dehumidifying function operates and the heating mode in which the dehumidifying function does not operate.

In an application scenario, the dehumidifying device enters a first working mode, namely a heating mode in which a dehumidifying function operates, the first air supply part, the second air supply part, the first heating part, the second heating part and the dehumidifying part operate, the air deflector rotates by taking a rotating shaft as a pivot to open the dehumidifying channel and the auxiliary channel, and the air supply channel is closed. Indoor air enters the dehumidifying equipment from the air inlet, part of the indoor air enters the dehumidifying channel, and when the indoor air passes through the dehumidifying part, the indoor air is cooled by heat exchange with the evaporator and releases condensed water, and then the indoor air is subjected to heat exchange with the condenser to raise a certain temperature; the other part flows to the auxiliary channel, and the two parts of air respectively flow through the outlet of the dehumidifying channel and the outlet of the auxiliary channel and then enter the air supply snail shell of the heating equipment. Because a part of air flows through the auxiliary channel, and the dehumidifying channel is farthest from the air inlet of the dehumidifying apparatus compared with the air supply channel and the auxiliary channel, the air flowing through the dehumidifying channel is reduced, the air speed is reduced, and the time for heat exchange with the heat medium in the dehumidifying part is increased, thereby improving the dehumidifying effect. Meanwhile, the dehumidification channel and the auxiliary channel are mutually independent, namely, air passing through the auxiliary channel cannot pass through the dehumidification channel, so that the air in the auxiliary channel cannot be blocked by the dehumidification part in the dehumidification channel, wind resistance is less, the air can smoothly reach heating equipment, and the air is heated by the first heating part and the second heating part and then blown into a room, so that the heating air quantity and the heating effect are improved. The dehumidifying equipment is positioned at the upstream side of the heating equipment, namely the dehumidifying part is positioned at the upstream side of the first air supply part and the second air supply part, so that after air enters the dehumidifying channel from the air inlet, the air can enter the air supply snail shell through the dehumidifying treatment of the dehumidifying part, and compared with the downstream sides of the first air supply part and the second air supply part, the dehumidifying equipment has relatively lower air speed at the upstream sides of the first air supply part and the second air supply part, so that the air has enough heat exchange time in the dehumidifying part and the dehumidifying effect can be improved; in addition, according to the principle that the higher the wind speed is, the larger the pressure loss is, the dehumidifying part is arranged on the upstream side of the first air supply part and the second air supply part, so that the pressure loss can be reduced, and the air quantity can be improved. In addition, the wind speed on the upstream side of the first air supply part and the second air supply part is low, so that the water on the evaporator can be prevented from being blown away due to the excessively high wind speed.

In practical application, the air quantity flowing through the dehumidifying part can be adjusted by adjusting the specific sizes of the dehumidifying channel and the auxiliary channel according to the required dehumidifying quantity, so that the heating effect can be ensured, and the dehumidifying effect can be improved.

In an application scenario, the dehumidifying device enters a second working mode, namely a heating mode in which a dehumidifying function does not operate, the first air supply part, the second air supply part, the first heating part and the second heating part operate, the dehumidifying part does not operate, the air deflector rotates to open the air supply channel by taking the rotating shaft as a pivot, and the auxiliary channel and the dehumidifying channel are closed. Indoor or outdoor air enters the dehumidification device from the air inlet, does not pass through the dehumidification portion, but flows to the air supply snail shell of the heating device through the air supply channel, so that pressure loss caused by the dehumidification portion is avoided, more air can smoothly reach the heating device, and is heated and then blown indoors, and heating air quantity and heating effect are ensured.

In the above two working modes, the second switching portion may change the switching position according to actual needs, and the second switching portion includes: a first switching position, a second switching position, and a third switching position; under the first switching position, the second heating air port is conducted, the ventilation port is closed, and air blown out by the second air supply part is blown out through the second heating air port; under the second switching position, the second heating air port is closed, the ventilation port is communicated, and air blown out by the second air supply part is blown out through the ventilation port; and under the third switching position, the second heating air port and the ventilation port are both conducted, and air blown out by the second air supply part is blown out through the second heating air port and the ventilation port.

In a possible embodiment, the dehumidifying apparatus may also be connected to a heat exchange apparatus, an air cleaning apparatus, etc. to constitute other kinds of air conditioning apparatuses.
