Description

Technical Field

[0002] The existing floor-standing air conditioner is equipped with a filter device at the air inlet to prevent dust from being sucked into the evaporator and the interior of the air conditioner.

Specific embodiments

[0058] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present utility model. On the contrary, they are merely examples of devices consistent with some aspects of the present utility model as detailed in the appended claims.

[0059] Currently, for the existing air conditioners, when cleaning the filter screen, it needs to be manually disassembled and cleaned, which is time-consuming and laborious. The embodiment of the present utility model proposes a cabinet air conditioner with reversible air supply. By arranging the filter screen on the outer periphery of the heat exchanger and controlling the movement of the filter screen through the dust removal device for cleaning, on the one hand, arranging the filter screen on the outer periphery of the heat exchanger can prevent the filter screen arranged at the air outlets {upper air outlet and / or lower air outlet} of the body from affecting the air output volume while ensuring the air filtering effect {the air supply mode of the reversible air conditioner is different from that of the ordinary cabinet air conditioner. The air outlets located on the upper and lower sides of the body can be used as both air inlets and air outlets. When the air outlet is used as the air outlet, adding a filter screen at the air outlet position will affect the air output volume of the air conditioner}, and on the other hand, by adding a dust removal device in the body, it can also control the movement of the filter screen and clean it, thus eliminating the need for manual cleaning of the filter screen.

[0060] The following combines the attached Figure 1 - attached Figure 8The technical solution of this embodiment will be elaborated in detail. Without conflict, the following implementation manners and embodiments can be combined with each other.

[0061] Embodiment

[0062] As Figures 1 - 8 shown, this embodiment provides a cabinet air conditioner, which includes:

[0063] A body 1, with an upper air outlet 11 provided at the top of the body 1, a lower air outlet 12 provided at the bottom of the body 1, and an air supply duct between the upper air outlet 11 and the lower air outlet 12 inside the body 1. The air conditioner has a single lower air outlet mode with air inlet from the upper air outlet 11 and air outlet from the lower air outlet 12, and a single upper air outlet mode with air inlet from the lower air outlet 12 and air outlet from the upper air outlet 11;

[0064] A heat exchanger 2, which is arranged in the air supply duct and is used for heat exchange of the air flow when the air conditioner operates in the single lower air outlet mode or the single upper air outlet mode;

[0065] A filter screen 3, which surrounds the outer periphery of the heat exchanger 2;

[0066] A dust removal device, which is arranged inside the body 1 and includes:

[0067] A driving mechanism, which is used to drive the filter screen 3 surrounding the outer periphery of the heat exchanger 2 to move;

[0068] A cleaning mechanism, which is used to clean the surface of the filter screen 3 when the filter screen 3 moves.

[0069] For the cabinet air conditioner provided by the embodiment of the present invention, by arranging the filter screen 3 on the outer periphery of the heat exchanger 2 and controlling the movement of the filter screen 3 and cleaning it through the dust removal device. On the one hand, arranging the filter screen 3 on the outer periphery of the heat exchanger 2 can ensure the air filtration effect while preventing the filter screen 3 arranged at the air outlets {the upper air outlet 11 and / or the lower air outlet 12} of the body 1 from affecting the air outlet volume {it should be noted that the air supply mode of the reversible air conditioner is different from that of the ordinary cabinet air conditioner. The air outlets on the upper and lower sides of the body 1 can be used as both air inlets and air outlets. If a filter screen is added at the air outlet position, it will affect the air outlet volume of the air conditioner when the air outlet is used}. On the other hand, by adding a dust removal device inside the body 1, the movement of the filter screen 3 can be controlled and it can be cleaned, thus eliminating the need for manual cleaning of the filter screen.

[0070] It should be noted that the cabinet air conditioner in the embodiment of the present utility model operates in a single downward air outlet mode in the heating mode and a single upward air outlet mode in the cooling mode. Since the hot air is lighter in mass and easily accumulates at the top of the room, operating in the single downward air outlet mode in the heating mode can make the hot air gradually fill the entire room from bottom to top, thereby improving the heating effect. Since the cold air is heavier in mass and easily accumulates at the bottom of the room, operating in the single upward air outlet mode in the cooling mode can make the cold air gradually fill the entire room from top to bottom, thereby improving the cooling effect.

[0071] It should also be noted that the cabinet air conditioner in the embodiment of the present utility model can adopt an existing air duct structure to achieve upward and downward reversible air outlet, and the embodiment of the present utility model does not specifically describe the air duct structure for realizing upward and downward reversible air outlet.

[0072] In any of the above embodiments, the above-mentioned filter screen 3 is a flexible filter screen;

[0073] The above-mentioned dust removal device further includes:

[0074] A support mechanism for supporting the filter screen 3 surrounding the heat exchanger 2, so that the shape of the filter screen 3 surrounding the heat exchanger 2 is adapted to the outer contour shape of the heat exchanger 2;

[0075] Wherein the filter screen 3 supported by the support mechanism on the outer periphery of the heat exchanger 2 is spaced apart from the outer surface of the heat exchanger 2 by a distance.

[0076] In the embodiment of the present utility model, by providing a support mechanism to support the filter screen 3, the filter screen 3 can be made more stable during movement. At the same time, the shape of the filter screen 3 supported by the support mechanism is adapted to the external contour shape of the heat exchanger, thereby preventing the filter screen from occupying a large space inside the body 1 and causing an increase in the size of the body 1. Further, by the support mechanism, the filter screen 3 is spaced apart from the outer surface of the heat exchanger 2, which can also prevent the filter screen 3 from interfering with the heat exchanger 2 during movement, thereby further improving the stability of the filter screen 3 during movement.

[0077] In any of the above embodiments, as Figures 2 - 8 shown, the support mechanism includes a plurality of support wheels 4 provided inside the body 1 and used for supporting the filter screen 3, and the plurality of support wheels 4 are all in transmission cooperation with the filter screen 3;

[0078] Wherein at least one of the plurality of support wheels 4 can be driven by a driving mechanism to rotate, so as to drive the filter screen 3 in transmission cooperation with it to move.

[0079] In the embodiment of the present utility model, by setting the support mechanism as the support wheel 4, on the one hand, the support effect on the filter screen 3 can be achieved, and on the other hand, the effect of driving the filter screen 3 to move can also be achieved.

[0080] Preferably, the support wheel 4 and the filter net 3 can be drivingly engaged with each other by means of frictional engagement or by means of gear meshing. In the embodiment of the present invention, the specific driving manner between the support wheel 4 and the filter net 3 is not limited.

[0081] It should be noted that, in some embodiments not shown, the support mechanism may also adopt other support members. For example, the support mechanism can be set as a support frame, and a separate set of driving mechanisms can be provided to drive the filter net 3 to move on the support frame.

[0082] In any of the above embodiments, the support positions of the plurality of support wheels 4 in the machine body 1 are designed as follows:

[0083] When the filter net 3 is supported by the plurality of support wheels 4, the shape of the filter net can be supported by the plurality of support wheels 4 to be adapted to the outer peripheral contour shape of the heat exchanger 2.

[0084] That is, in the embodiment of the present invention, by designing the positions of the plurality of support wheels 4, on the one hand, the filter net 3 can be supported, and on the other hand, the shape of the supported filter net 3 can be adapted to the shape of the heat exchanger 2, thereby preventing the filter net 3 from occupying a large space in the machine body 1 and causing the machine body 1 to have a large size.

[0085] In any of the above embodiments, as Figures 2 - 5 shown, among the plurality of support wheels 4, there is included an active support wheel 41 and a plurality of driven support wheels 42;

[0086] Among them, the active support wheel 41 is drivingly connected to the driving mechanism.

[0087] That is, when the air conditioner in the embodiment of the present invention drives the filter net 3 to move, only one support wheel needs to be used as the active wheel, so that only one power source needs to be provided to realize the driving of the filter net 3, thereby reducing the manufacturing cost of the machine body 1.

[0088] In any of the above embodiments, the cleaning mechanism includes:

[0089] A cleaning component, the cleaning component can be driven to move, and when the cleaning component is driven to move, it can be attached to or separated from the surface of the filter net 3;

[0090] When the cleaning component is driven to move to a position where it is attached to the surface of the filter net 3, the cleaning component can clean the surface of the filter net 3. When the cleaning component is driven to move to a position where it is separated from the surface of the filter net 3, the cleaning component can avoid the filter net 3.

[0091] When it is necessary to clean the filter net 3, the cleaning component can be driven to fit the surface of the filter net 3, and at the same time, the filter net 3 is driven to move, so that the surface of the moving filter net 3 can be cleaned by the cleaning component, thereby realizing the self-cleaning effect of the filter net 3.

[0092] Specifically, as Figure 3 , Figure 5 and Figure 7 shown, the cleaning component includes a brush 5 that can be driven to rotate and a scraper 6 that can be driven to rotate;

[0093] When the brush 5 is driven to rotate, it has a first rotation position A and a first rotation position B. When the brush 5 is in the first rotation position A, the brush 5 fits the surface of the filter net 3, and when the brush 5 is in the first rotation position B, the brush 5 is separated from the surface of the filter net 3;

[0094] When the scraper 6 is driven to rotate, it has a second rotation position A and a second rotation position B. When the scraper 6 is in the second rotation position A, the scraper 6 fits the surface of the filter net 3, and when the scraper 6 is in the second rotation position B, the scraper 6 is separated from the surface of the filter net 3.

[0095] In the embodiment of the present utility model, by setting the cleaning component as a combination of the brush 5 and the scraper 6, different degrees of cleaning of the filter net 3 can be achieved through the combination of the two.

[0096] It should be noted that the hardness of the brush 5 is greater than that of the scraper 6. The scraper is a flexible silica gel plate for cleaning the floating dust on the surface of the filter net, and the brush 5 is used to clean the dust that is difficult to clean on the filter net 3.

[0097] Specifically, the air conditioner further includes:

[0098] A gas sensor, which is arranged at the upper air outlet 11 position and / or the lower air outlet 12 position;

[0099] A controller, which is used to control the rotation position of the brush and / or the rotation position of the scraper according to the detection data of the gas sensor;

[0100] Wherein the gas sensor is used to detect the air quality and / or air flow rate at the upper air outlet 11 position and / or the lower air outlet 12 position.

[0101] Taking the gas sensor detecting the air quality at the upper air outlet 11 position and / or the lower air outlet 12 position as an example, the rotation position of the brush and / or the rotation position of the scraper is controlled.

[0102] Specifically;

[0103] After the gas sensor detects that the air quality value at the upper air inlet 11 or the lower air inlet 12 is greater than or equal to the set air quality value, the filter net 3 can be cleaned normally at this time: At this time, the brush 5 can be controlled to rotate to the first rotation position B separated from the surface of the filter net, and the scraper 6 can be controlled to rotate to the second rotation position A attached to the surface of the filter net, that is Figure 3 As shown, at this time, only the scraper 6 contacts the surface of the filter net to clean the floating dust on the surface of the filter net {Preferably, the scraper 6 is a silica gel plate}, and the brush does not contact the filter net 3.

[0104] When the gas sensor detects that the air quality value at the upper air inlet 11 or the lower air inlet 12 is lower than the set air quality value, the filter net 3 can be deeply cleaned at this time; At this time, the brush 5 can be controlled to rotate to the first rotation position A attached to the surface of the filter net, and the scraper 6 can be controlled to rotate to the second rotation position A attached to the surface of the filter net 3, that is Figure 5 As shown, at this time, the scraper 6 and the brush 5 contact the filter net at the same time to clean the dust that is difficult to clean on the filter net {Preferably, the brush is used to clean dirt such as dust with greater viscosity, etc.}.

[0105] In any of the above embodiments, as Figure 3 , Figure 5 and Figure 6 shown, the above cleaning mechanism further includes:

[0106] A dust collection box 7, the dust collection box 7 is arranged below the cleaning component, and is used to collect the dust that falls off when the cleaning component cleans the filter net 3;

[0107] Among them, the dust collection box 7 is detachably installed inside the machine body 1, and at least part of the dust collection box is exposed on the surface of the machine body 1, so that the dust collection box 7 can be disassembled and assembled outside the machine body 1.

[0108] Preferably, in the embodiment of the present invention, the dust collection box adopts a pull-out structure design, which is convenient for the user to take out and clean, and prevents the active support wheel 41 from accumulating dust and jamming.

[0109] Furthermore, as Figure 6 shown, the cleaning mechanism further includes:

[0110] A brush motor 8, the brush motor 8 is used to drive the brush 5 to rotate;

[0111] A scraper motor 9, the scraper motor 9 is used to drive the scraper 6 to rotate;

[0112] The drive mechanism includes a support wheel motor 10, and the support wheel motor is used to drive the active support wheel 41 to rotate;

[0113] The dust removal device further includes;

[0114] A fixed mounting frame 20, wherein the active support wheel 41, the support wheel motor 10, the brush 5, the brush motor 8, the scraper 6 and the scraper motor 9 are integrated on the fixed mounting frame 20 and form an integral component with the fixed mounting frame 20;

[0115] The dust collection box installed in the body 1 is located below the overall component and is detachably connected to the overall component;

[0116] Cleaning teeth are also protruding from the fixed mounting frame, wherein the brush is driven to rotate to the first rotation position B and contacts the cleaning teeth so that the brush is cleaned by the cleaning teeth.

[0117] In the embodiment of the utility model, the active support wheel 41, the support wheel motor 10, the brush 5, the brush motor 8, the scraper 6 and the scraper motor 9 are integrated on the fixed mounting frame 20, which can facilitate the installation of the above components when producing the body 1 and improve the installation efficiency. At the same time, the cleaning teeth are protruding on the fixed mounting frame, which can also achieve a self-cleaning effect on the brush 5.

[0118] In any of the above embodiments, if Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the heat exchanger 2 is constructed as a V-shaped heat exchanger with an opening upward in the height direction of the body 1;

[0119] The V-shaped heat exchanger 2 has an upper heat exchange surface opposite to the upper air port 11, a lower heat exchange surface opposite to the lower air port 12, and a side wall surface between the upper heat exchange surface and the lower heat exchange surface, and the upper heat exchange surface and the lower heat exchange surface constitute the heat exchange surface of the heat exchanger;

[0120] The filter screen 3 is disposed around the outer periphery of the heat exchange surface of the heat exchanger 2 and avoids the side wall surface of the heat exchanger 2 .

[0121] The specific working mode of the air conditioner is as follows Figure 7 and Figure 8 As shown, the evaporator of the reversible air supply air conditioner is V-shaped.

[0122] like Figure 8 As shown, when the air conditioner is in cooling mode, air flows in from the lower air outlet and is blown out from the upper air outlet, and the air flows in contact with the lower heat exchange surface of the V-shaped evaporator. Therefore, dust will gather on the filter screen on the lower heat exchange surface of the heat exchanger. Therefore, it is necessary to clean the dust on the filter screen on the lower heat exchange surface side. Specifically, the filter screen can be driven to rotate clockwise by a driving mechanism so that the surface of the filter screen can be cleaned by a brush and / or a scraper.

[0123] like Figure 7As shown, when the air conditioner is in the heating mode, the air flow enters from the upper air outlet and blows out from the lower air outlet. The air flow contacts the upper heat exchange surface of the V-shaped heat exchanger. Therefore, dust will accumulate on the filter screen of the upper heat exchange surface of the heat exchanger. So at this time, it is necessary to clean the dust on the filter screen on the side of the upper heat exchange surface. Specifically, the filter screen can be driven to rotate counterclockwise by a driving mechanism to clean the surface of the filter screen through a brush and / or a scraper.

[0124] In summary, in the embodiment of the present invention, the air conditioner can realize self-cleaning of the filter screen of the air conditioner through the above structure, so that there is no need to manually clean the filter screen of the air conditioner.

[0125] After considering the specification and practicing the embodiments disclosed herein, those skilled in the art will readily conceive of other embodiments of the present invention.
