With reference to fig. 1 and 2, an embodiment of the present disclosure provides a decarbonization module for indoor use, including: the device comprises an air inlet part 10, a power part 20, an air outlet part 30 and a switching device 40, wherein the air inlet part 10 is provided with an adsorption component capable of adsorbing and desorbing carbon dioxide; the power part 20 is communicated with the air inlet part 10 and is configured to drive air flow to enter the air inlet part 10; the air outlet part 30 comprises an indoor air outlet part 31 and an outdoor air outlet part 32, and both the indoor air outlet part 31 and the outdoor air outlet part 32 are communicated with the power part 20; the switching device 40 is disposed in the power unit 20 and configured to switch the power unit 20 between the indoor air outlet portion 31 and the outdoor air outlet portion 32.

The embodiment of the present disclosure may provide an indoor carbon dioxide removal module to realize the adsorption and removal of carbon dioxide in indoor air, and desorb the adsorbed carbon dioxide and discharge the desorbed carbon dioxide to the outdoor. Specifically, the adsorption and desorption of carbon dioxide can be realized by arranging the adsorption component, and the air inlet portion 10, the air outlet portion 30, the power portion 20 and the switching device 40 are arranged to realize the switching of the air flow directions of indoor air outlet and outdoor air outlet.

The embodiment of the present disclosure provides an adsorption module capable of adsorbing and desorbing carbon dioxide in the air inlet portion 10, and the indoor air can pass through the air inlet portion 10 and be discharged from the air outlet portion 30 by driving of the power portion 20, and the adsorption module can adsorb carbon dioxide in the indoor air and also can desorb the adsorbed carbon dioxide. When the indoor carbon dioxide needs to be removed, the indoor air outlet part 31 is switched on through the switching device 40, indoor circulation is started, and carbon dioxide in indoor air is adsorbed through the adsorption component; after the indoor carbon dioxide is removed, the outdoor air outlet part 32 can be switched on through the switching device 40, outdoor circulation is started, the adsorption component desorbs the carbon dioxide to discharge the carbon dioxide to the outdoor, so that the adsorption component recovers the adsorption capacity of the carbon dioxide, and the adsorption removal effect of the carbon dioxide is kept.

The carbon dioxide removal module is divided into two operation modes of indoor circulation (carbon dioxide adsorption) and outdoor exhaust (carbon dioxide desorption), and the wind directions of the two modes are switched by the switching device 40.

As an example, the switching device 40 is provided in the power unit 20, and switches the power unit 20 to the indoor air outlet unit 31 when it is necessary to remove indoor carbon dioxide, and switches the power unit 20 to the outdoor air outlet unit 32 when it is necessary to discharge carbon dioxide. Therefore, under the condition that indoor carbon dioxide needs to be removed, the carbon dioxide removing module can start indoor circulation, so that indoor air is adsorbed by the carbon dioxide removing module to remove carbon dioxide and is discharged back to the indoor environment again, and the indoor air quality is improved; under the condition that carbon dioxide needs to be discharged, the carbon dioxide removing module can start outdoor circulation, so that carbon dioxide is desorbed from the adsorption component and then is discharged outdoors, and the adsorption component recovers the adsorption capacity of the carbon dioxide.

As an example, the indoor air outlet portion 31 includes a first pipe, one end of which communicates with the power portion 20, the other end of which communicates with the indoor space, and the other end of which has an indoor air outlet. Thus, the airflow is discharged from the power unit 20 and then is discharged from the indoor outlet back into the room through the first pipe.

Optionally, the first pipeline is vertically arranged, the bottom of the first pipeline is communicated with the power portion 20, and the indoor air outlet is located at the top of the first pipeline. Thus, an indoor air outlet with an upward direction can be formed, and the air flow can be blown upwards and returned to the indoor. When the carbon dioxide removal module is applied to an air conditioner, air can be supplied from above the air conditioner.

When the carbon dioxide removing module is applied to an on-hook air conditioner, the indoor air outlet portion 31 and the power portion 20 may be disposed at the left and/or right side of the air conditioner main body. Therefore, the carbon dioxide removing module can be well matched with the structure of the air conditioner on-hook, so that the whole structure is more compact and reasonable.

As an example, the outdoor air outlet portion 32 includes a second pipeline, one end of which is communicated with the power portion 20, the other end of which extends to the outdoor and is communicated with the outdoor, and the other end of which is provided with an outdoor air outlet. Thus, the airflow is discharged from the outdoor outlet to the outside through the second duct after flowing out from the power unit 20.

Alternatively, the second conduit extends first against the housing of the power section 20 and then extends away from the power section 20. Thus, the outdoor air outlet part 32 and the power part 20 are relatively compact in structure.

As one example, the adsorbent assembly includes an adsorbent material 50 capable of adsorbing and desorbing carbon dioxide. The adsorbent 50 can separate carbon dioxide from indoor air by adsorbing carbon dioxide, and then can release carbon dioxide again into the air by desorbing carbon dioxide. The adsorbent 50 may be an existing adsorbent 50 capable of adsorbing and desorbing carbon dioxide.

In some embodiments, the power portion 20 includes a fan chamber 21 and a transition chamber 23, a fan 22 is disposed in the fan chamber 21, and the airflow inlet is communicated with the air inlet portion 10; the transition chamber 23 is communicated with an airflow outlet of the fan chamber 21 and is communicated with an indoor air outlet part 31 and an outdoor air outlet part 32; wherein the switching device 40 is arranged in the transition chamber 23.

In the disclosed embodiment, when fan 22 is rotated, negative pressure is formed in fan compartment 21, and indoor air enters air inlet portion 10, then enters fan compartment 21 from an airflow inlet, and flows into transition compartment 23 from an airflow outlet of fan compartment 21. When the switching device 40 controls to switch on the indoor air outlet part 31, the airflow flows into the indoor through the indoor air outlet part 31; when the switching device 40 controls to switch on the outdoor air outlet portion 32, the airflow flows into the outdoor space through the outdoor air outlet portion 32.

The power part 20 is arranged in two parts of the fan chamber 21 and the transition chamber 23, the fan 22 is limited in the fan chamber 21, and the switching device 40 is arranged in the transition chamber 23, so that the position interference between the fan 22 and the switching device 40 can be avoided, and the airflow can smoothly enter the transition chamber 23 from the fan chamber 21. The switching device 40 is in the transition chamber 23

As an example, the fan compartment 21 is disposed adjacent to the transition compartment 23, which facilitates the connection between the fan compartment 21 and the transition compartment 23 and enables smooth airflow from the fan compartment 21 into the transition compartment 23.

As an example, the indoor air outlet portion 31 is disposed above the transition chamber 23, the outdoor air outlet portion 32 is disposed at one side of the transition chamber 23, and the fan chamber 21 is disposed at the other side of the transition chamber 23. Thus, the layout of the fan chamber 21, the transition chamber 23, the indoor air outlet portion 31 and the outdoor air outlet portion 32 is compact and reasonable, airflow can conveniently flow through the fan chamber 21, the transition chamber 23 and the indoor air outlet portion 31/outdoor air outlet portion 32 in sequence, and the switching device 40 can conveniently switch on the indoor air outlet portion 31 and the outdoor air outlet portion 32.

As one example, the fan 22 is a centrifugal fan 22. The centrifugal fan 22 accelerates the gas using an impeller rotating at a high speed, and then decelerates and changes the flow direction, so that kinetic energy is converted into potential energy (pressure). In the centrifugal fan 22, the gas enters the impeller from the axial direction, changes to the radial direction as it flows through the impeller, and then flows out from the airflow outlet of the fan housing 21. The centrifugal fan 22 has large air volume and air pressure, and can effectively improve the carbon dioxide removal effect on indoor air.

In some embodiments, the switching device 40 comprises a blocking assembly movably disposed within the transition chamber 23 and a drive mechanism; the driving mechanism is connected with the blocking assembly, and drives the blocking assembly to rotate between a first position and a second position, the blocking assembly closes the airflow inlet of the indoor air outlet portion 31 in the first position, and closes the airflow inlet of the outdoor air outlet portion 32 in the second position.

Under the drive of actuating mechanism, the blocking component rotates between a first position and a second position, wherein the first position is the position of the indoor air outlet part 31 of the blocking component blocking room, and the second position is the position of the outdoor air outlet part 32 of the blocking component blocking room.

As an example, the airflow inlet of the indoor air outlet portion 31 and the airflow inlet of the outdoor air outlet portion 32 are at an angle of 90 degrees. Like this, the blocking subassembly can be through rotating the airflow import that switches the indoor air-out portion 31 of blocking and the airflow import of outdoor air-out portion 32 to the rotation route of blocking subassembly is shorter, and the smooth flow direction of also being convenient for air current is indoor air-out portion 31 or outdoor air-out portion 32.

As an example, the blocking assembly comprises a rotating shaft and a baffle plate, and the driving mechanism is connected with the rotating shaft. The driving mechanism drives the rotating shaft to rotate, and then drives the baffle to rotate.

As one example, the drive mechanism includes a motor including a drive shaft coupled to a shaft of the blocking assembly. The drive shaft of motor rotates, can drive the pivot and rotate, and then drives the baffle and rotate.

In some embodiments, the airflow outlet of the fan compartment 21 communicates with the bottom of the transition chamber 23 and the airflow inlet of the indoor air outlet 31 communicates with the top of the transition chamber 23. Like this, under the condition of auto-change over device 40 switch-on indoor air-out portion 31, the air current flows out from the top of fan room 21, then need not to change flow direction, can directly upwards flow and get into the airflow inlet of indoor air-out portion 31, can keep amount of wind and wind pressure as far as possible, is favorable to going on of indoor circulation, promotes the effect of getting rid of indoor carbon dioxide.

And, indoor air-out portion 31 can send the air after having got rid of carbon dioxide back to indoor through the air supply that upwards, can avoid the air current directly to blow indoor to promote user experience.

In some embodiments, the airflow inlet of the outdoor air outlet 32 is disposed on a sidewall of the transition chamber 23. Thus, when the switching device 40 turns on the outdoor air-out portion 32, the airflow flows out from the top of the fan housing 21, enters the outdoor air-out portion 32 from the airflow inlet located on the side wall of the transition chamber 23, and is discharged to the outside through the outdoor air-out portion 32. The airflow inlet of the outdoor air outlet part 32 is arranged on the side wall of the transition chamber 23, and can be close to the airflow inlet of the indoor air outlet part 31, so that the switching device 40 can be switched to be connected with different airflow inlets conveniently.

In some embodiments, the air inlet portion 10 includes a first air duct 11 and a second air duct 12, and the first air duct 11 is provided with an air inlet communicated with the indoor; one end of the second air duct 12 is communicated with the first air duct 11, and the other end is communicated with the power part 20; wherein, the adsorption component is disposed in the first air duct 11. In the embodiment of the present disclosure, indoor air enters the first air duct 11 from the air inlet, and carbon dioxide therein is adsorbed by the adsorption component and enters the power unit 20 through the second air duct 12; or, the indoor air enters the first air duct 11 from the air inlet, the adsorption assembly desorbs carbon dioxide, and only the second air duct 12 mixed with the carbon dioxide enters the power unit 20.

In some embodiments, the first air chute 11 extends in a horizontal direction and the second air chute 12 extends in a vertical direction. Thus, the indoor air flows horizontally in the first duct 11, and flows in the vertical direction after entering the second duct 12.

As an example, when the decarbonation module is applied to an on-hook air conditioner, the first air duct 11 may be disposed at a lower portion of a main body of the air conditioner, and the second air duct 12 may be disposed at a left or right side of the main body. Like this, first wind channel 11 extends along the lower part level of main part, and second wind channel 12 vertically extends and is located the left side or the right side of main part, makes except that the carbon dioxide module can be well adapted with the air conditioner on-hook, arranges the below and the side of air conditioner on-hook in, pleasing to the eye and reduce the space and occupy.

Moreover, the air inlet and the indoor air outlet can be far away from each other, the indoor air circulation range is improved, and the effect is better. And, first wind channel 11 extends along the horizontal direction, and the adsorbent material 50 that its inside was filled is also comparatively slim, can prolong the contact time of air and adsorbent material 50, and the adsorption effect is better.

In some embodiments, the adsorbing assembly includes an adsorbing material 50 and a heating element 51, the adsorbing material 50 being disposed in the first air duct 11; the heating member 51 is connected to the adsorbent 50 and configured to heat the adsorbent 50 to desorb carbon dioxide from the adsorbent 50.

When the heating member 51 heats the adsorbing material 50, the adsorbing material 50 can desorb carbon dioxide. In the indoor circulation (carbon dioxide adsorption) process, the heating element 51 is closed and is in a low-temperature air inlet state, and carbon dioxide is adsorbed after indoor air flows through the adsorbing material 50; during the outdoor circulation (carbon dioxide desorption), the heating element 51 is turned on, the carbon dioxide is desorbed after the temperature of the adsorbing material 50 rises, and the carbon dioxide is mixed into the air stream after the indoor air passes through the adsorbing material 50.

As an example, the heating member 51 is an electric heating member 51. The use of an electric heating element 51 facilitates the heating of the adsorbent material 50.

As an example, a screen 52 is provided at the air inlet. Through setting up filter screen 52, can filter impurity such as dust in the room air, avoid it to get into except that in the carbon dioxide module.

As an example, the first air duct 11, the filter screen 52 and the electric heating element 51 are all of a plug-in structure, so that cleaning and maintenance are facilitated.
