An indoor unit 100 for an air conditioner according to an embodiment of the present invention is described below with reference to fig. 1 to 23. The indoor unit 100 may be applied to an air conditioner. The air conditioner may be a cooling and heating machine having both cooling and heating functions, or may be a single cooling machine having only cooling functions. In the following description of the present application, the application of the indoor unit 100 to a cooling and warming machine will be described as an example.
As shown in fig. 1 to 23, an indoor unit 100 for an air conditioner according to an embodiment of the first aspect of the present invention includes a main body for hanging, a heat exchanger 2, a wind wheel 3, a filter screen 4, a dust sweeping mechanism 5, and an electric control unit.
Specifically, the top of the hanging machine body is provided with an air inlet 11, the bottom of the hanging machine body is provided with an air outlet 12, and an air deflector 121 for opening and closing the air outlet 12 is arranged at the air outlet 12. The air deflector 121 can control the opening and closing of the air outlet 12, and can adjust the air outlet quantity and the air outlet direction. The hanging machine body is formed with a dust discharge opening 13 for discharging dust, hair, etc. in the hanging machine body.
The heat exchanger 2 and the wind wheel 3 are arranged in the hanging machine body, and the heat exchanger 2 is arranged adjacent to the air inlet 11. The wind wheel 3 is located downstream of the heat exchanger 2. Here, "downstream" is understood to mean downstream in the flow direction of the air flow. When the air conditioner is in refrigeration or heating operation, for example, the air flow entering the hanging machine body from the air inlet 11 exchanges heat with the heat exchanger 2 and flows to the wind wheel 3.
The filter screen 4 is arranged between the air inlet 11 and the heat exchanger 2, and the filter screen 4 can be used for filtering dust, hair and the like in the air flow entering the hanging machine body from the air inlet 11 so as to ensure the cleanliness of the air flow blown out from the air outlet 12, and simultaneously ensure the cleanliness of the inside of the hanging machine body. Specifically, the sieve 4 includes a conducting portion 41 and a closing portion 42 connected to each other, the sieve 4 is movable between a first position (as shown in fig. 15 b) in which the conducting portion 41 is opposite to the air intake 11, and a second position (as shown in fig. 19 a) in which the closing portion 42 is opposite to the air intake 11, and when the sieve 4 is in the first position, the air flow entering from the air intake 11 is adapted to flow through the conducting portion 41 to the heat exchanger 2, so that the air conditioner such as a cooling and heating machine can be operated smoothly; the closing portion 42 closes a portion of the air intake 11 when the sieve 4 is in the second position, so as to facilitate the subsequent execution of the dust removal mode.
The dust sweeping mechanism 5 comprises a first driving mechanism 51 and a brush 52 matched with the first driving mechanism 51, the first driving mechanism 51 is used for driving the brush 52 to rotate so as to brush dust and hair on the conducting part 41 in the process of moving the filter screen 4 from the first position to the second position, the brush 52 is opposite to a non-closed part 42 (for example, a part which is not closed by the closed part 42) of the air inlet 11 when the filter screen 4 is in the second position, when the air deflector 121 closes the air outlet 12 and the wind wheel 3 rotates, and air flow entering from the non-closed part 42 of the air inlet 11 is suitable for flowing through the brush 52 under the driving of the wind wheel 3 so as to bring the brushed dust and hair to the dust discharging port 13. Wherein, by arranging the brush 52 opposite to the non-closed part 42 of the air inlet 11, when the filter screen 4 is at the second position, the wind wheel 3 operates, and the air flow entering from the non-closed part 42 of the air inlet 11 can smoothly flow to the brush 52, thereby the dust and hair brushed from the conducting part 41 can be well taken away and conveyed to the dust discharge opening 13.
The electric control assembly comprises a controller (not shown), two conductive terminals and a potential detection device, wherein the two conductive terminals are electrically connected with the filter screen 4 and are arranged on the filter screen 4 at intervals, the potential detection device is electrically connected with the controller, and the potential detection device is used for detecting potential difference between the two conductive terminals. When the air conditioner works, the filter screen 4 can be electrically connected with an electric control component in the electric control assembly through the two conductive terminals, and the filter screen 4 is electrified at the moment, so that the air conditioner has a strong adsorption effect on dust (for example, 10-100 micrometers) in the air, and the cleanliness of the air flow entering from the air inlet 11 is improved. The electric potential detection device can detect the electric potential difference between the two conductive terminals, the electric potential difference between the two conductive terminals is the electric potential difference of the filter screen 4 at the moment, the controller compares the detected electric potential difference with the dust removing electric potential difference preset in the electric potential difference, and when the electric potential difference is greater than or equal to the dust removing electric potential difference, the filter screen 4 does not need to be cleaned at the moment; when the above potential difference is smaller than the dust removing potential difference, the air conditioner enters a dust removing mode to clean dust, hair, etc. adhering to the filter screen 4. Therefore, the filter screen 4 dirt blocking detection mode is directly aimed at the filter screen 4, that is, the filter screen 4 dirt blocking state is directly monitored, and the accuracy of detection results is improved.
For example, when the indoor unit 100 of the air conditioner is applied to an air conditioner such as a cooling/warming machine, the air deflector 121 opens the air outlet 12, the wind wheel 3 rotates, the air conditioner is operated to cool or heat, and as shown in fig. 15a and 15b, the air flow entering from the air inlet 11 sequentially passes through the filter screen 4, the heat exchanger 2, and the wind wheel 3 and then is blown out from the air outlet 12, which is a normal air supply state.
As shown in fig. 16 and 17, when the air conditioner is turned off after the air conditioner operates in the cooling and heating modes, or after a dust removing key on a remote controller of the air conditioner is pressed, the air conditioner enters intelligent dust removing detection, at this time, the air conditioner detects the potential difference of the filter screen 4 through the potential detecting device and compares the potential difference with a preset dust removing potential difference in the controller to determine the following actions: when the potential difference is greater than or equal to the dedusting potential difference, the filter screen 4 is not required to be cleaned at the moment, the air conditioner can be normally shut down, and a dedusting green light indication is fed back to a user; when the potential difference is smaller than the dedusting potential difference, the air conditioner enters a dedusting mode.
As shown in fig. 18 to 20, after the air conditioner enters the dust removing mode, the filter screen 4 is moved from the first position to the second position, and in the above process, the brush 52 is rotated to brush down dust, hair, etc. on the conductive portion 41 of the filter screen 4, when the filter screen 4 is moved to the second position, the closing portion 42 of the filter screen 4 closes a portion of the air inlet 11, the air deflector 121 is closed to close the air outlet 12, the wind wheel 3 is started, and the air flow outside the on-hook body can enter the on-hook body from the non-closing portion 42 of the air inlet 11 and flow to the brush 52, thereby taking the dust, hair, etc. brushed down from the conductive portion 41 of the filter screen 4, and sending the dust, hair to the dust discharge port 13.
According to the indoor hanging machine 100 of the air conditioner, provided by the embodiment of the invention, the dirt blocking state of the filter screen 4 can be directly monitored by arranging the two conductive terminals and the electric potential detection device, so that the accuracy is improved. In addition, in the working process of the indoor unit 100, the filter screen 4 is electrified and has a strong adsorption effect on dust and the like, so that the filtering effect of the filter screen 4 is improved.
According to some embodiments of the present invention, referring to fig. 3 in combination with fig. 11 and 12, the on-hook body includes a grill 14, two guide grooves 141 are provided on the grill 14 to be opposite to each other, and conductive coatings 142 are coated on inner walls of the two guide grooves 141, wherein both ends of the filter screen 4 are respectively movably fitted into the two guide grooves 141 and contacted with the conductive coatings 142, and the two conductive terminals are respectively electrically connected with the conductive coatings 142 in the two guide grooves 141. Thus, by providing the guide groove 141 on the grill 14, the guide groove 141 has a good guide effect on the movement of the screen 4, and by coating the conductive coating 142 on the inner wall of the guide groove 141, the conductive terminal can be electrically connected with the screen 4 through the conductive coating 142 without moving together with the screen 4. Further, the two conductive terminals are connected with the two conductive terminals through conductive patches respectively.
As shown in fig. 13, the closing portion 42 of the screen 4 is in a fully closed form, and the conducting portion 41 is in a normal screen 4 form. The wires of the filter screen 4 are in a wire structure, and the conducting part 41 is in contact with the conductive coating 142 in the guide groove 141 of the grille 14, so that two ends of the grille 14 have a safe potential difference.
According to some embodiments of the present invention, as shown in fig. 4-7, the first driving mechanism 51 includes a first driving motor and a first transmission gear 511 matched with the first driving motor, wherein the brush 52 is fixedly connected with the first transmission gear 511, the brush 52 is preferably coaxially arranged with the first transmission gear 511, and the filter screen 4 is provided with a plurality of meshing teeth 43 meshed with the first transmission gear 511. Therefore, by adopting the driving mode of the first driving motor and the first transmission gear 511, the first driving mechanism 51 can drive the brush 52 to rotate and simultaneously drive the filter screen 4 to move in the guide groove 141, so that the bristles 521 on the brush 52 can well eject dust, hair and the like in the meshes of the filter screen 4, and further, the filter screen 4 is cleaned, and the structure is compact and simple and is easy to realize.
As shown in fig. 15b to 16, 19a and 22, each of the guide grooves 141 includes a first guide groove 1411 opposite to the air inlet 11 and a second guide groove 1412 bypassing the first driving gear 511 and having both ends communicating with the first guide groove 1411. The first guide channel 1411 is substantially flush with the air inlet 11 and is disposed immediately adjacent to the air inlet 11, whereby a better filtering effect is achieved when the screen 4 is in the first position. By providing the second guide groove 1412 in a form of bypassing the first transmission gear 511, the remaining parts of the dust sweeping mechanism 5 except the first transmission gear 511 and the brush 52 can be shielded by the closing part 42 of the filter screen 4 when the filter screen 4 is located at the first position; when the filter screen 4 is in the second position, the filter screen 4 may have a certain guiding effect on the air flow entering from the non-closed portion 42 of the air inlet 11, so as to guide most of the dust, hair, etc. to the dust discharge opening 13.
According to some embodiments of the invention, the conducting portion 41 completely covers the air intake 11 when the sieve 4 is in the first position. At this time, the conduction portion 41 entirely covers the air intake 11. Thus, a better filtering effect can be achieved.
When the sieve 4 is in the second position, the closing portion 42 closes a substantial part of the air intake 11. For example, the closing portion 42 may close 80% of the area of the air inlet 11, but is not limited thereto. It will be appreciated that the area of the sealing portion 42 for sealing the air inlet 11 may be specifically set according to practical requirements, so as to better meet practical applications.
Wherein, the filter screen 4 is preferably a conductive structure, so that the filter screen 4 is integrally processed and manufactured, the processing efficiency is improved, and the cost is reduced. Of course, the entire edge of the screen 4 and the conducting portion 41 may be of a conductive structure, and the central portion of the closing portion 42 other than the edge may be made of a non-conductive material.
According to some embodiments of the present invention, since the filter screen 4 is constructed of wires and has the ability to be electrically conductive as a whole, conductive patches are attached in the guide grooves 141 of the grill 14 and connected with corresponding parts in the electronic control box of the electronic control assembly by connection wires of conductive terminals (e.g., flat terminals) to transmit current signals, as shown in fig. 17.
After the operation of the air conditioner is finished or a user presses a dust removing key on a remote controller of the air conditioner, entering a filter screen 4 filth blocking detection mode, regarding the filter screen 4 and corresponding components in an electric control box connected through a conductive terminal as a simple loop, controlling the loop by the controller, outputting a detection potential difference at the tail end, comparing the detection potential difference with a dust removing potential difference preset in the controller, when the detection potential difference is smaller, starting dust sweeping action by the system, otherwise, directly shutting down the system, and outputting a green prompt. The dust removing potential difference is a preset value in the controller and is used for comparing with the currently returned detection potential difference in a difference mode.
According to a further embodiment of the present invention, the dust sweeping mechanism 5 further comprises: the second driving motor, the second transmission gear of intermeshing and third transmission gear, second transmission gear cooperates with the second driving motor, be equipped with on the second transmission gear and sweep the dirt strip 53, be equipped with the fender 54 on the third transmission gear, sweep dirt strip 53 and brush 52 contact in the course of filter screen 4 moves from the first position to the second position in order to be suitable for sweeping dust and hair on the brush 52 and fender 54 is located the side that is away from air intake 11 of brush 52 and heat exchanger 2 so that the air current that gets into from the non-closure 42 part of air intake 11 flows to dust exhaust port 13, sweep dirt strip 53 and brush 52 and fender 54 are located between brush 52 and heat exchanger 2 when filter screen 4 is located the first position. Thus, by providing the stopper 54 and the dust-sweeping bar 53, when the filter screen 4 is located at the first position, the remaining parts of the dust-sweeping mechanism 5 excluding the first transmission gear 511 and the brush 52 can be sealed by the closing part 42 of the filter screen 4 and the face frame 16 in the hanging machine body, etc., to prevent local air leakage. In the process of moving the filter screen 4 from the first position to the second position, the first transmission gear 511 drives the filter screen 4 to move in the guide groove 141, the brush hair 521 on the brush 52 ejects dust or hair 200 and the like on the filter screen 4, the dropped dust is brushed down by the dust sweeping bar 53, and the dust sweeping bar 53 is used for cleaning dust and hair and the like attached to the brush 52, so that on one hand, the cleanness of the brush 52 is ensured, and on the other hand, the brushed dust and hair and the like can conveniently flow to the dust discharge port 13 along with the airflow.
Specifically, the on-hook body includes a face frame 16, and referring to fig. 15b and 19a in combination with fig. 15c and 19b, the stopper 54 includes: the first blocking portion 541 and the second blocking portion 542, one end of the first blocking portion 541 is connected to the second transmission gear, one end of the second blocking portion 542 is connected to the other end of the first blocking portion 541, the other end of the second blocking portion 542 extends towards the direction of the heat exchanger 2, when the filter screen 4 is located in the second position, the first blocking portion 541 is suitable for guiding the air flow to the heat exchanger 2, and when the filter screen 4 is located in the first position, the second transmission gear and the third transmission gear are separated from the air duct formed by the air inlet 11, the heat exchanger 2, the wind wheel 3 and the air outlet 12 by the blocking member 54, the face frame 16 and the sealing portion 42. For example, the first blocking portion 541 is preferably a flat plate structure, and the second blocking portion 542 is preferably an arc-shaped structure protruding toward the heat exchanger 2. When the filter screen 4 is in the first position, the blocking part rotates to the position shown in fig. 15b and 15c, and at this time, the blocking part can seal the second transmission gear, the third transmission gear, the dust sweeping bar 53 and the like of the dust removing mechanism together with the sealing part 42 and the face frame 16 and the like of the filter screen 4, so that the purpose of preventing local air leakage is achieved. When the screen 4 is in the second position, the blocking part is turned to the position shown in fig. 19a and 19b, where the first blocking part 541 extends obliquely upwards in a direction towards the heat exchanger 2, so that the air flow through the brush 52 can be better directed towards the dust discharge opening 13 and the heat exchanger 2.
According to alternative embodiments of the present invention, as shown in fig. 10a to 10c, the second driving gear is provided with a dust bar shaft 531 coaxially arranged with the second driving gear, the dust bar shaft 531 is provided with a mounting hole 532 penetrating through a sidewall of the dust bar shaft 531, one end of the dust bar 53 is mounted in the mounting hole 532, and the other end of the dust bar 53 extends out of the mounting hole 532 to be suitable for sweeping dust and hair on the brush 52.

According to some embodiments of the present invention, the hanging machine body comprises a chassis 15, and a water receiving tray is arranged on the chassis 15, wherein the dust discharging port 13 is communicated with the water receiving tray. For example, the dust discharge opening 13 may also be provided on the chassis 15. Thereby, dust, hair, etc. discharged from the dust discharge port 13 can fall into the water pan, and finally be discharged outdoors with condensed water, etc. in the water pan. At this time, the dust discharge pipe 17 need not be separately provided.
Of course, the present invention is not limited thereto, and according to other embodiments of the present invention, the hanging machine body may be further provided with a dust exhaust pipe 17, and the dust exhaust pipe 17 communicates with the dust exhaust port 13. Thereby, dust, hair, etc. on the screen 4 can be discharged outside through the dust discharge port 13 via the dust discharge pipe 17.
Wherein in the dust removal mode the rotor 3 is operated at a lower rotational speed (e.g. lowest gear rotational speed). The indoor unit 100 may enter a breeze mode at this time. Therefore, the rotating speed of the wind wheel 3 is low, so that the power consumption is low, the noise is low, and the principle of economy and environmental protection is met.
Further, as shown in fig. 5, the indoor unit 100 further includes a sealing cover 55, and when the dust removing mechanism 5 is installed in the main body of the indoor unit, the sealing cover 55 is located at substantially the front side of the entire dust removing mechanism 5. Thus, by providing the seal cover 55, the seal cover 55 can function as a shield for the dust sweeping mechanism 5 on the rear side thereof, and the seal cover 55 can be detached when cleaning of the dust sweeping mechanism 5 is required or parts (e.g., the first transmission gear 511, the brush 52, etc.) thereon are replaced.
The specific operation modes of the air conditioner, such as the cooling and warming machine, when the air conditioner indoor unit 100 is applied to the air conditioner, such as the cooling and warming machine, are described in detail with reference to fig. 15a to 23 as follows:
when the air conditioner is operated, for example, in cooling or heating operation, as shown in fig. 15a and 15b, the air deflector 121 is rotated to open the air outlet 12, the filter screen 4 is at the first position, the dust sweeping bar 53 on the dust sweeping mechanism 5 is disengaged from the brush 52, the baffle member 54 is located between the brush 52 and the heat exchanger 2, the wind wheel 3 is started, the air flow entering from the air inlet 11 flows through the filter screen 4 to filter the air flow, and the filtered clean air flow exchanges heat with the heat exchanger 2 and then flows through the wind wheel 3 to be sent into a room from the air outlet 12.
When the air conditioner is turned off after the air conditioner, such as a cooling and heating machine, operates in a cooling or heating mode, or after a dust removing key on a remote controller of the air conditioner is pressed, the air conditioner, such as a cooling and heating machine, enters intelligent dust removing detection, as shown in fig. 16 and 17, at this time, the potential difference at both sides of the filter screen 4 is detected by the potential detecting device, and the potential difference is compared with a dust removing potential difference preset in the controller:
when the potential difference is greater than or equal to the dedusting potential difference, the filter screen 4 is not required to be cleaned at the moment, and the air conditioner such as a cold or warm machine can be normally shut down, and a dedusting green light indication is fed back to a user;
when the above potential difference is smaller than the dust removing potential difference, the air conditioner, such as a cooling and heating machine, enters a dust removing mode.
As shown in fig. 18 to 20, after an air conditioner such as a cooling and heating machine enters a dust removal mode:
the engagement teeth 43 on the filter screen 4, by cooperation with the first transmission gear 511 on the dust sweeping mechanism 5, move the closing part 42 towards the air inlet 11 until the air inlet 11 is completely closed for the vast majority by moving to the position shown in fig. 19 a. In this process, the brush 52 rotates to eject dust, hair, etc. on the conductive portion 41 of the screen 4, and the dropped dust, hair, etc. is brushed down by the dust-sweeping bar 53.
The air deflector 121 is driven to close the air outlet 12.
The baffle 54 rotates by a certain angle to lead the air duct to be communicated with the dust sweeping mechanism 5.
Then, the rotational speed of the indoor unit 100 of the air conditioner is controlled to enter a breeze mode, and the wind wheel 3 runs at a lower rotational speed. The flow direction of the air flow is shown by the arrow in fig. 19a, the air flow only enters from the non-closed part 42 of the air inlet 11 and enters the interior of the air duct through the middle space of the dust sweeping mechanism 5, specifically, the air flow flows to the dust sweeping mechanism 5, then is carried away and flows through the heat exchanger 2 and the wind wheel 3 in sequence, and then flows to the dust exhaust port 13.
Among them, dust, hair, and the like can be classified into two types:
1. small particle dust, hair and the like can enter the dust discharging pipe 17 from the dust discharging port 13 on the chassis 15 and enter the outdoor;
2. large particle dust, hair, etc. adhere to the heat exchanger 2 and are removed by self-cleaning as described below.
As shown in fig. 21-23, the self-cleaning mode of the heat exchanger 2 is as follows:
the screen 4 rotates back to the first position, the rotor 3 stops, and the deflector 121 remains closed.
The air conditioner, such as a cold and warm machine, firstly operates in a refrigerating mode, a large amount of water is generated and frozen due to the fact that the heat exchanger 2 does not exchange heat, when the required frosting amount is reached, the heat exchanger 2 begins to heat, the ice is melted into water by heating, the water flows down along the fins of the self-lubricating heat exchanger 2, dust, hair and the like attached to the heat exchanger 2 are washed down and sent outdoors along the water channel of the chassis 15 and the water receiving disc.
According to the indoor unit 100 of the air conditioner of the embodiment of the present invention, the dust sweeping mechanism 5 reduces a plurality of sealing members and a dust box as compared with the existing structure, and does not need to use an external dust collector to absorb the dust falling from the filter screen 4. In addition, the dust sweeping action is controlled more intelligently, and the dust sweeping command is controlled by detecting the dirt blocking of the filter screen 4, so that the indoor hanging machine 100 of the air conditioner can not sweep dust every time when the indoor hanging machine is shut down, but can execute operation according to criteria set by a program. In addition, the dust removal effect is better, and the filter screen 4 has a partial sealing function according to structural design, plays the role of shielding a main air inlet and guiding flow in the dust removal mode, and guides most of dust into the reserved dust exhaust pipe 17. In addition, dust can be removed from the water channels of the chassis 15 according to different particle sizes, and some dust can not be removed and accumulated on the heat exchanger 2 in a self-cleaning mode, so that the overall cleaning effect is more thorough, and manual cleaning is less or not required. The indoor unit 100 of the air conditioner according to the embodiment of the invention has a simple structure and is convenient to install and repair.
As shown in fig. 1 to 23, the air conditioner according to the second aspect of the present invention, such as a control method of a cooling/warming machine, includes the air conditioner indoor unit 100 and the air conditioner remote controller according to the above-described first aspect of the present invention.
The control method comprises the following steps:
when the air conditioner is in refrigerating or heating operation, the filter screen 4 is positioned at a first position;
when the air conditioner is shut down after stopping cooling or heating operation (for example, when cooling or heating is not needed and the air conditioner is ready to be shut down), or after a dust removing key on a remote controller of the air conditioner is pressed down, the potential difference between the two conductive terminals is detected by the potential detecting device to obtain a detection potential difference, and the detection potential difference is compared with a dust removing potential difference preset in the controller;
when the detected potential difference is greater than or equal to the dedusting potential difference, the air conditioner is normally shut down;
when the detected potential difference is smaller than the dedusting potential difference, the air conditioner enters a dedusting mode.
According to the control method of the air conditioner, such as the cooling and heating machine, provided by the embodiment of the invention, the filth blockage detection is directly aimed at the filter screen 4 by adopting a potential difference detection mode, so that the accuracy of a detection result is improved. The air conditioner such as the cold and warm machine can independently judge whether dust sweeping is needed, and the air conditioner is completely intelligent and energy-saving.
According to some embodiments of the invention, the dust removal mode specifically comprises the steps of:
controlling the filter screen 4 to move from the first position to the second position, in which the brush 52 brushes off dust and hair on the conducting part 41;
Controlling the air deflector 121 to close the air outlet 12;
the control dust sweeping bar 53 is contacted with the hairbrush 52, and the baffle piece 54 is positioned on one side of the hairbrush 52 and the heat exchanger 2, which is far away from the air inlet 11;
the wind wheel 3 is controlled to rotate at the lowest gear speed so that the air flow entering from the non-closed portion 42 of the air inlet 11 flows through the brush 52 to bring the brushed dust and hair toward the dust discharge opening 13.
Therefore, the dust sweeping action control is more intelligent, the dust sweeping command is controlled by detecting the dirt blocking of the filter screen 4, and the air conditioner such as a cold air conditioner cannot sweep dust every time when the air conditioner is shut down, but can execute operation according to criteria set by a program.
According to some embodiments of the invention, after controlling the rotor 3 to rotate at the lowest gear speed,
the dust removal mode further comprises the following steps:
controlling the filter screen 4 to move from the second position to the first position;
the wind wheel 3 is controlled to stop rotating;
controlling the air conditioner to perform refrigeration operation so as to freeze the heat exchanger 2;
the air conditioner is operated to heat so that ice on the heat exchanger 2 is melted into water to wash down dust and hair attached to the heat exchanger 2 and to deliver to the water pan.
Thus, self-cleaning of the filter screen 4 and the heat exchanger 2 can be realized, and the overall cleaning effect of the indoor unit 100 is more thorough, so that no or less manual cleaning is required.
It should be noted that, the specific control method of the air conditioner, such as the cooling and warming machine, is described in detail at the indoor hanging machine 100 of the air conditioner in the embodiment of the first aspect of the present invention, and will not be described herein again.
