The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The cabinet air conditioner 100 according to the embodiment of the present invention is described in detail below with reference to fig. 1 to 17.

As shown in fig. 1 in conjunction with fig. 9, 10, 13 and 16, the cabinet air conditioner 100 according to the embodiment of the present invention may generally include: a machine base 10, a plurality of air supply columns 20, a first heat exchanger 41 and an air flow driving member 30.

Specifically, as shown in fig. 1 and fig. 5, the base 10 forms an air cavity 101 having an air return opening 11, the plurality of air supply columns 20 are disposed on the base 10, each air supply column 20 forms an air duct 201 having an air outlet 211, the air duct 201 is communicated with the air cavity 101, the first heat exchanger 41 is disposed in the air cavity 101 for cooling or heating the air flow entering the air cavity 101, and the air flow driving member 30 is disposed in the base 10 and/or in the air supply column 20 for driving the air flow to circulate into the air duct 201.

It can be understood that, because the size of the cabinet air conditioner 100 in the length direction is large, the center of gravity of the cabinet air conditioner is not suitable to be set high, otherwise, the cabinet air conditioner is easy to topple over to damage the body of the cabinet air conditioner and even injure a user. According to the present invention, the first heat exchanger 41 is disposed in the base 10, and the base 10 is disposed below the air supply column 20, such that the center of gravity can be lowered, and the anti-toppling effect can be achieved.

In the above embodiments, as shown in fig. 1 and fig. 4, the airflow driving member 30 is disposed in the base 10 and/or the air supply column 20, that is, the airflow driving member 30 may be disposed in the base 10 to further reduce the center of gravity, or disposed in the air supply column 20, the airflow driving member 30 is closer to the air outlet 211, so that the air outlet distance is longer, or the air supply column is further disposed

20 and the base 10 are both provided with airflow driving parts 30, and the air quantity can be increased and the air supply distance can be increased by arranging a plurality of airflow driving parts 30.

According to the cabinet air conditioner 100 provided by the embodiment of the invention, the first heat exchanger 41 is arranged on the base 10, so that the weight of the base 10 can be increased, and the weight of the air supply column 20 can be reduced relatively, that is, the gravity center of the cabinet air conditioner 100 can be moved downwards, so that the cabinet air conditioner 100 can be placed more stably, and the cabinet air conditioner 100 has a better anti-toppling effect and higher safety performance.

As shown in fig. 5, each air supply column 20 extends in the vertical direction, and accordingly, the air duct 201 also extends in the vertical direction. The air supply column 20 is arranged to extend along the vertical direction, the air duct 201 extends along the vertical direction, the air outlet flow is blown out from the air duct 201 in a compliance mode, the coverage area along the vertical direction is wide, more parts of a human body can be taken care of, instead of blowing air in a small local area, and a user can feel the air blowing effect more uniformly.

As shown in fig. 13, 14, 15, 16, and 17, the second heat exchanger 42 is provided in the air supply column 20, and the air flow flowing out of the air chamber 101 enters the air duct 201 after having been subjected to heat exchange by the second heat exchanger 42. By arranging a plurality of heat exchangers 40, the air flow can be sufficiently heat-exchanged to reach the preset temperature, and the indoor temperature can be quickly reached.

Preferably, the first heat exchanger 41 and the second heat exchanger 42 operate relatively independently, that is, the second heat exchanger 42 does not operate when the first heat exchanger 41 operates, the first heat exchanger 41 does not operate and the second heat exchanger 42 operates, or the first heat exchanger 41 and the second heat exchanger 42 operate simultaneously. When a single heat exchanger 40 works, energy loss can be reduced, an energy-saving effect is achieved, and when a plurality of heat exchangers 40 work simultaneously, indoor temperature can be quickly reached.

The windward side of the second heat exchanger 42 is smaller than the inlet flow surface of the air duct 201, and the second heat exchanger 42 is positioned at the top of the air supply column 20. It can be understood that, when the air current after passing through the heat exchange of the first heat exchanger 41 in the air cavity 101 enters the air duct 201, because the air duct 201 extends along the vertical direction, the temperature of the air current can gradually change in the direction far away from the base 10, and the second heat exchanger 42 is arranged at the top of the air supply column 20, so that the effect of heat compensation can be achieved, the temperature of the air current in the air duct 201 tends to be consistent, and thus, the temperature of the air current blown out from the air outlet 211 is uniform, and the body feeling is good.

Of course, the above embodiments are only illustrative, and should not be construed as limiting the scope of the present invention, for example, the air supply column 20 includes a housing, the housing is provided with an air inlet grille, the air inlet grille extends along a vertical direction, the air inlet grille is communicated with the air duct 201, the second heat exchanger 42 is arranged between the air duct 201 and the air inlet grille and extends along the vertical direction, so that the air supply column 20 can supply air through the air inlet grille, and the air flow enters the air duct 201 after separately exchanging heat through the second heat exchanger 42.

At least one wind supply post 20 is rotatably provided on the housing 10. For example, taking the plurality of air supply columns 20 as two air supply columns 20 and one of the two air supply columns 20 can rotate relative to the base 10, wherein one of the air supply columns 20 rotates, the air flows blown out from the air outlets 211 of the two air supply columns 20 are blown out toward each other, and two air flows with approximately the same air direction are formed in the middle area of the two air supply columns 20, so that the air flow blown out from the air outlet 211 of the air supply column 20 and the air flow blown out from the air outlet 211 of the other air supply column 20 are converged wholly or partially and then blown out in a direction away from the air supply column 20, and at this time, the air flows blown out from the two air supply columns 20 are converged to form one air flow, that is, at this time, the cabinet air conditioner 100 is in a strong air mode, and achieves ultra-distance directional air supply; or one of the air supply columns 20 rotates, the air flows blown out from the air outlets 211 of the two air supply columns 20 face each other, and when the two air flows meet, the two air flows have a certain included angle, so that the air flow blown out from the air outlets 211 of the air supply columns 20 collides with the air flow blown out from the air supply outlet of the other air supply column 20, after the collision, the direction and the flow speed of the air flow can be changed to a certain extent, the two air flows change into large-area air supply at the downstream of the collision area, and the kinetic energy is lost due to the collision, so that the air speed can be reduced, the wind-free air supply is realized, and at the moment, the cabinet air conditioner 100 is in a collision mode; or one of the air supply columns 20 rotates, and the air flows blown by the two air supply columns 20 diffuse beyond the direction far away from each other, so that the air flows blown by the two air supply columns 20 do not interfere with each other, thereby realizing large-range air supply, realizing full-room surrounding air supply and uniform air blowing, and at the moment, the cabinet air conditioner 100 is in a surrounding air mode.

As shown in fig. 2 and 3, two symmetrically arranged air supply columns 20 are arranged at the top of the machine base 10, and outlets of the two air supply columns 20 are opposite. The air outlets 211 of the two air feeding columns 20 are oppositely arranged, the air flows blown by the two air feeding columns 20 can be blown in the direction of approaching each other, and the air flows blown by the air outlets of the two air feeding columns 20 can be converged or collided with each other more conveniently.

Of course, in other embodiments, the air outlets 211 of the two air supply columns 20 may also be arranged away from or parallel to each other, so as to realize air blowing in different directions and areas. The above-described various modes of blowing can be also realized by rotating the blowing columns 20.

In the present application, at least one air supply column 20 is rotatably disposed on the base 10, and two air supply columns 20 can be controlled independently or in linkage with each other, taking the example that the air supply column 20 includes two air supply columns:

one of the air supply columns 20 is rotatably disposed on the base 10, and the other air supply column 20 is fixedly connected to the base 10. By providing one of the air supply columns 20 to be rotatable, the number of driving members and transmission members can be reduced, simplifying the structure.

The two air supply columns 20 are both rotatable, mode switching can be achieved more quickly, the positions of the air outlets 211 of the two air supply columns 20 can be changed, the air supply range is large, and more room areas can be covered.

As shown in fig. 1, 13 and 15, one of the two air supply columns 20 supplies normal temperature air, and the other one supplies cooling air or heating air. Also two air supply columns 20 can blow off the air current of different temperatures, realize the differentiation air supply, and the air supply scope at two air outlets 211 is different, in same time, can satisfy different demands, if blow normal atmospheric temperature natural wind, cold wind or hot-blast, when there is alternately in the air supply scope of two air outlets 211, the air current that two air outlets 211 flow can mix to heat transfer each other, realize mixing the air-out effect, avoid blowing off the air current reach human body after the human body feels comparatively unhardened supercooling or the overheated sense.

As shown in fig. 1, the airflow driving member 30 includes a plurality of members, a centrifugal fan 31 is disposed in the housing 10, and a cross-flow fan 32 is disposed in the blowing column 20.

Through setting up the new trend module, can exchange indoor and outdoor air to guarantee that the room air is fresh, thereby avoid the room air to become turbid under airtight condition for a long time and influence the health. Specifically, the centrifugal fan 31 drives outdoor fresh air to enter the fresh air duct 201, and then the fresh air is driven by the cross flow fan 32 to enter the air duct 201 in the air supply column 20 and is blown out from the air outlet 211, so that the freshness of indoor air can be ensured.

It should be understood that the normal temperature wind inlet 212 herein does not mean that the inlet only can flow the normal temperature wind, and in fact, the air flowing into the normal temperature wind inlet 212 is the indoor air, that is, the temperature of the air flowing into the wind duct 201 from the normal temperature wind inlet 212 is the indoor air temperature. By arranging the normal-temperature air inlet 212, a part of air flow enters the air supply column 20 through the normal-temperature air inlet 212, and is mixed with another air flow which flows into the air duct 201 from the inside of the base 10 after heat exchange through the heat exchanger 40 and then is blown out from the air outlet 211, so that the two air flows with different temperatures can be mixed and heat exchanged in the air duct 201, the air flow blown out from the air duct 201 is closer to the room temperature, the temperature difference between the part of air flow and the room temperature is smaller, the body feeling of a user is better, and the body feeling cannot be influenced by blowing a harder cold air or hot air.

A control method of a cabinet air conditioner according to an embodiment of the present invention, which is applicable to the cabinet air conditioner of the above-described embodiment, is described in detail below with reference to fig. 1, 18 to 19.

In some embodiments, as shown in fig. 1, the cabinet air conditioner in this embodiment includes a base 10 and a plurality of air supply columns 20, the base 10 forms an air chamber 101 having an air return opening 11, the plurality of air supply columns 20 are disposed on the base 10, each air supply column 20 forms an air duct 201 having an air outlet, the air duct is communicated with the air chamber 101, a first heat exchanger 41 is disposed in the air chamber 101, and the first heat exchanger 41 is used for cooling or heating an air flow entering the air chamber 101.

In this embodiment, the control method of the cabinet air conditioner includes the following steps: the instruction executed by the cabinet air conditioner 100 in the current state is determined. The execution command includes, but is not limited to, a cooling command to start or stop, a heating command to start or stop, an air supply direction, an air supply range, an air supply mode, and the like.

For example, the cabinet air conditioner 100 may control the air supply column 20 to work in a cooling state and a heating state, or may adjust the air supply mode of the cabinet air conditioner 100 to be a left air supply mode, a right air supply mode, a no-wind-sensation mode, and the like according to the user requirement, and taking the left air supply mode as an example, the air supply column 20 located on the left may be controlled to be turned off or operated at a low wind speed, and the air supply column 20 located on the right may be turned on at a suitable wind speed, so as to implement air supply in the left direction; similarly, the right air supply mode controls the air supply column 20 located on the right to be closed or to be operated at a low air speed, and the air supply column 20 located on the left to be opened at a suitable air speed, thereby achieving air supply in the left direction. On the basis, according to the requirements of users, the cabinet air conditioner 100 can also be selected to work in a cooling state or a heating state, and according to the requirements of users for different powers, the number of the air supply columns 20 which are opened and closed can also be selected, and air supply parameters and air supply modes such as the positions or movement tracks of the air supply columns 20 can be controlled. The cabinet air conditioner 100 controls at least one of the air supply columns 20 according to the execution command under the current condition, so as to control the air supply quantity, the air direction and the like of the air supply column 20 corresponding to the cabinet air conditioner 100.

It can be understood that the control method of the present invention can control the air supply parameter or the air supply mode of a certain air supply column 20 alone or control the overall air supply direction and air supply temperature by controlling the movement tracks of a plurality of air supply columns 20, and can use the air in different directions to synthesize and overlap to make the cabinet air conditioner work in different operation modes under different instructions, that is, the air flows of a plurality of air supply columns 20 can be overlapped to synthesize the air flow in a certain direction, that is, the air supply temperature of the cabinet air conditioner 100 can be obtained by adjusting the air supply temperature of a plurality of air supply columns 20, thereby meeting the air demand of different people in different time periods in different areas.

For example, in the case that the cabinet air conditioner 100 has two air supply columns 20, one air supply column 20 may be kept stationary, and the other air supply column 20 rotates, for example, when strong air supply to a certain direction is required, two air supply columns 20 may be started to supply air to the same direction, for example, when air supply temperature needs to be adjusted, one air supply column 20 may supply cold air, and the other air supply column 20 may supply normal temperature air, and the cold air and the normal temperature air are mixed to form comfortable air meeting user body feeling. It is understood that the air supply mode of the cabinet air conditioner 100 can be coordinated in various ways according to the needs, and is not limited to the above.

As shown in fig. 18, in a further embodiment, when two air supply columns 20 which are arranged at an interval and are rotatable with respect to the base 10 are arranged on the base 10, and air outlets of the two air supply columns 20 are arranged oppositely, at least one air supply column 20 is controlled according to a current execution instruction, and an execution instruction of the cabinet air conditioner 100 is a wide-angle air supply instruction, so as to supply air in a wider wide-angle range through the air supply columns 20. The method for controlling the cabinet air conditioner provided with the two air supply columns comprises the following steps:

s201, when the current execution command of the cabinet air conditioner 100 is a wide-angle air supply command, controlling the two air supply columns 20 to rotate in the same direction (both counterclockwise and both clockwise), and when one air supply column 20 rotates to the limit position in the current direction, stopping the rotation until the other air supply column 20 rotates to the limit position in the current direction.

This step can be understood as a reset operation before the control of the cabinet air conditioner 100, and due to the needs of the user, the movement position of the air supply column 20 at a certain time may not be determined, and it is difficult to perform periodic control to obtain accurate air supply parameters such as air supply speed and wind direction; and at uncertain positions, the time difference caused by the difference of the stroke distance of the movement to the respective extreme positions, which makes the movement start in the same direction, wherein the same direction can rotate clockwise or counterclockwise simultaneously. Therefore, the reset process is designed to stop the air supply column 20 which reaches the limit position first, and wait for the other air supply column 20 to reach the corresponding limit position, so as to ensure that the current position of the air supply column 20 is known, realize synchronous control, and make the air supply process more controllable, and the following control steps can adjust the parameters of the air supply speed, the movement direction and the movement speed of the air supply column 20, so as to make the cabinet air conditioner 100 convenient for the control requirement of the next step, and further realize the synchronization of the movement state of the air supply column 20.

And S202, when the two air supply columns 20 reach the limit positions, controlling the two air supply columns 20 to rotate in the opposite directions simultaneously, and controlling the air supply speed of the two air supply columns 20 to change simultaneously in the process of controlling the air supply columns 20 to rotate in the opposite directions.

By controlling the two air supply columns 20 to run at the same speed and in the same direction, a synchronous and periodic movement is achieved. Alternatively, the air supply parameters such as air supply speed and the like or the air supply mode can be controlled to be periodically changed in the movement process so as to meet the requirements of temperature or air quantity in different occasions. For example, when the user needs the air conditioner to work in a low wind mode or a no wind mode and needs to control the temperature, in the moving process, the two air supply columns 20 can be controlled to move to a place with high overlap ratio of air supply ports to increase the air supply speed, and when the overlap ratio is low, the air speed is reduced.

Referring to fig. 19, in a further embodiment, the wind speeds of the two wind columns are controlled to change respectively during the process that the two wind columns rotate in opposite directions simultaneously, and the wind columns 20 are controlled to move to the limit positions through the control of the previous step, and the control is performed according to the current limit positions, and the method includes the steps of:

and S203, when the two air supply columns 20 are positioned at the left limit position, controlling the air supply speed of the air supply column 20 at the left side to gradually increase from a preset minimum air speed to a preset maximum air speed when the left air supply column in the two air supply columns 20 rotates from the preset leftmost limit position to the preset rightmost limit position, and controlling the air supply speed of the air supply column 20 at the right side to gradually decrease from the preset maximum air speed to the preset minimum air speed when the air supply column 20 at the right side rotates from the preset leftmost limit position to the preset rightmost limit position.

In the process that the air supply columns 20 move to the limit position on the right side, taking the right air supply mode as an example, the overlapping part of the air supply outlets of the two air supply columns 20 is larger, so that the air convection caused by the opposite air supply directions when the air supply columns move to the position reduces the composite air, and the effect of wide-angle air supply is influenced. Therefore, the air supply speed of the right air supply column 20 is reduced at the respective limit positions, so that the air blown out from the left air supply column 20 and blown to the right side is as large as possible, and optionally, the movement speed of the air supply column 20 is controlled to be accelerated when the air supply column moves to the periphery of the limit positions, so that the energy loss is reduced, and the utilization efficiency of energy is improved simultaneously under the condition that a customer needs a certain air volume in a large-angle area.

And S204, when the two air supply columns 20 are at the right limit position, controlling the air supply speed of the left air supply column to gradually decrease from the preset maximum air speed to the preset minimum air speed when the left air supply column of the two air supply columns rotates from the preset rightmost limit position to the preset leftmost limit position, and controlling the air supply speed of the right air supply column to gradually increase from the preset minimum air speed to the preset maximum air speed when the right air supply column of the two air supply columns rotates from the preset rightmost limit position to the preset leftmost limit position.

Similarly, in order to ensure that the two air supply columns 20 cooperate to supply air to the wide-angle area on the left, it is necessary to reduce the air supply speed of the left air supply column 20 when the convection is large, thereby reducing the energy consumption and simultaneously ensuring wide-angle air supply in the left direction.

In the above control flow, the position change of the air supply column 20 and the air supply speed are periodically controlled in synchronization and are matched with each other, so that air supply in a wide-angle range can be realized. Compared with the prior art, the control method can obviously increase the air supply angle, thereby meeting the use requirements of users on the cabinet air conditioner 100 to a greater extent. In addition, according to the control method in this embodiment, the requirement of the operation mode under the execution instruction, such as the start or stop of the cooling instruction, the start or stop of the heating instruction, the air supply direction, the air supply range, the air supply mode, and the like, can be fulfilled.
