[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] In view of the water-washing self-cleaning of the air conditioner filter, it is necessary to collect the condensed water on the evaporator and enter the cleaning tank, and clean the filter in the cleaning tank. The structure is relatively complicated, and the roller brush is always in the cleaning tank storing the condensed water, which is easy to breed bacteria and cause secondary pollution. The embodiment of the present application provides an indoor unit, including: a shell, the shell is provided with an air inlet, and the shell is provided with: a filter, which is arranged at the air inlet; a first cleaner, which is used to dry brush the second cleaner; a second cleaner, which is used to clean the filter; a transmission device, which can controllably drive the filter and the first cleaner to move relative to the second cleaner, so that the second cleaner cleans the filter, or the first cleaner dry brushes the second cleaner.

[0044] It can be understood by those skilled in the art that the filter and the first cleaner in the present application can be connected, and one of them can be connected to the transmission device, or the filter and the first cleaner are not connected, and the two are installed on the transmission device respectively, as long as the transmission device can drive the two to move synchronously. In addition, the second cleaner can dry brush or clean the filter, and the first cleaner needs to dry brush the second cleaner to ensure that the second cleaner will not be immersed in water for a long time to prevent bacteria from growing.

[0045] In order to have a more specific understanding of the technical ideas of the present application, the exemplary embodiments are described below in conjunction with the accompanying drawings:

[0046] Figure 1 A layout diagram of a non-cleaning state of an indoor unit provided in an embodiment of the present application; Figure 2 A layout diagram of the steps for cleaning the filter screen of an indoor unit provided in an embodiment of the present application; Figure 3 A layout diagram of a second cleaning step of an indoor unit provided in an embodiment of the present application; Figure 4 A layout diagram of a second cleaning step of an indoor unit provided in an embodiment of the present application; Figure 5 A step diagram of a cleaning method for an indoor unit provided in an embodiment of the present application.

[0047] Reference Figure 1-Figure 5 As shown, an embodiment of the present application provides an indoor unit, including: a shell 100, wherein an air inlet is arranged on the shell 100, and the shell 100 is provided with: a filter 200 arranged at the air inlet; a first cleaner 300, used for dry brushing a second cleaner 400; a second cleaner 400, used for cleaning the filter 200; a transmission device 500, which can controllably drive the filter 200 or the first cleaner 300 to move relative to the second cleaner 400, so that the second cleaner 400 cleans the filter 200, or the first cleaner 300 dry brushes the second cleaner 400.

[0048] In the indoor unit provided in the embodiment of the present application, the transmission device 500 can drive the filter 200 and the first cleaner 300 to move. When the filter 200 moves to the corresponding position with the second cleaner 400, the second cleaner 400 cleans the filter 200, and there is no need to collect condensed water from the evaporator 600 to wash the filter 200. When the first cleaner 300 moves to the corresponding position with the second cleaner 400, the first cleaner 300 dry-brushes the second cleaner 400, thereby avoiding the problem in the related art that the second cleaner 400 is immersed in water for a long time, causing secondary pollution and breeding of bacteria, and automatically cleans the second cleaner 400, further improving the cleanliness and saving labor costs and time costs.

[0049] It should be noted that, in order to simplify the structure, the transmission device 500 can drive the filter screen 200 and the first cleaner 300 to move synchronously.

[0050] As for the transmission device 500, it mainly includes a transmission component and at least one first motor 52. The shape of the transmission component is adapted to the interior of the shell 100, and is used to connect the filter 200 and the first cleaner 300 to drive the two to move synchronously reciprocatingly or cyclically. The specific implementation method is that the filter 200 and the first cleaner 300 are independently installed on the transmission component, or the filter 200 and the first cleaner 300 are connected, so that at least one of them is installed on the transmission component.

[0051] This embodiment uses the two to be installed separately on the transmission component for further explanation. The transmission component includes a conveyor belt 511 and a support roller 512. The conveyor belt 511 forms a closed structure. The support roller 512 rolls and supports the conveyor belt 511 at the position where the conveyor belt 511 changes its transmission direction, and changes the transmission direction of the conveyor belt 511 from a straight line to a curve. The first motor 52 is one or two. When there is one, it abuts against the inner side of the closed space formed by the conveyor belt 511 to tighten the conveyor belt 511 from one side. When there are two, it abuts against both sides of the closed space formed by the conveyor belt 511 to tighten the conveyor belt 511 from both sides. The first motor 52 can drive the conveyor belt 511 to rotate clockwise or counterclockwise to drive the filter screen 200 and the filter screen 200 and the first cleaner 300 to move back and forth, and correspond to the second cleaner 400 respectively.

[0052] For the first cleaner 300, its function is to clean the second cleaner 400, so the first cleaner 300 is made of a plurality of comb teeth, and the plurality of comb teeth are evenly spaced on the conveyor belt 511. In order to allow the conveyor belt 511 to pass smoothly through the support roller 512, the comb teeth can be formed of an easily deformable material, such as rubber. When the conveyor belt 511 with comb teeth passes through a pair of support rollers 512, the comb teeth are deformed to allow the conveyor belt 511 to pass through, and the second cleaner 400 is dry-brushed with the comb teeth to clean large particles of dust on the second cleaner 400.

[0053] In addition, an evaporator 600 and a connector are disposed in the shell 100, wherein the evaporator 600 is disposed on the side of the filter 200 away from the air inlet, the connector surrounds the end of the evaporator 600, and a water collecting tank 700 is formed between the connector and the end of the evaporator 600. When dry brushing the filter 200 and the second cleaner 400, the fallen dust can fall into the water collecting tank 700 and form dust precipitation through condensed water, which is convenient for one-time cleaning later.

[0054] Further, for the second cleaner 400, the second cleaner 400 is arranged between the first cleaner 300 and the evaporator 600, and the second cleaner 400 is configured to be moved from the filter 200 to the evaporator 600, and the fine particles of the second cleaner 400 are cleaned with the condensed water generated during the operation of the evaporator 600, so as to complete the overall cleaning of the second cleaner 400, and the condensed water after cleaning falls into the sump 700, so as to realize the collection of sewage, and the moving range of the second cleaner 400 is outside the sump 700, so as not to cause secondary pollution to the second cleaner 400 due to long-term immersion, and in addition, the cleaned second cleaner 400 can be heated and evaporated by the heat generated during the operation of the evaporator 600, so as to remove the water vapor on the second cleaner 400, so as to facilitate the later use of the second cleaner 400. In order to drive the rotation of the second cleaner 400, the transmission device 500 also includes a second motor, and the second motor drives the second cleaner 400 to rotate in a clockwise direction or a counterclockwise direction.

[0055] In a second aspect, an embodiment of the present application provides an air conditioner, comprising the indoor unit described in any embodiment of the first aspect.

[0056] Thirdly, Figure 1-5 As shown, the embodiment of the present application provides a cleaning method for an indoor unit, comprising the following steps: Figure 2 As shown, cleaning the filter 200: moving the filter 200 to the first position, and making the filter 200 reciprocate in the first position, cleaning the filter 200 with the second cleaner 400: judging whether the filter 200 is cleaned: judging whether the filter 200 is cleaned, if not, repeating the step of cleaning the filter 200, and if so, performing the step of cleaning the second cleaner 400; Figure 3 As shown, cleaning the second cleaner 400 : the first cleaner 300 is moved to the first position, and the first cleaner 300 is reciprocated at the first position, so that the first cleaner 300 cleans the second cleaner 400 .

[0057] The cleaning method of the indoor unit provided in the embodiment of the present application does not involve cleaning with condensed water of the evaporator 600 in the two steps of cleaning the second cleaner 400, thereby reducing the problem of bacterial growth caused by cleaning with condensed water, and the second cleaner 400 does not need to be soaked in water to prevent secondary contamination.

[0058] The step of cleaning the second cleaner 400 also includes: controlling the second cleaner 400 to rotate from the first position to the empty position, moving the first cleaner 300 to the first position, and then controlling the second cleaner 400 to rotate from the empty position back to the first position.

[0059] After the step of cleaning the second cleaner 400, the method further includes: determining whether the cleaning of the second cleaner 400 is completed; if not, repeating the step of cleaning the second cleaner 400; if yes, performing the step of cleaning the second cleaner 400 and moving the filter 200 to the first position; Figure 4 As shown, cleaning the second cleaner 400: controlling the second cleaner 400 to move to the second position, and cleaning the second cleaner 400 with condensed water from the evaporator 600; second cleaner 400 cleaning determination: determining whether the second cleaner 400 has been cleaned, if not, repeating the steps of cleaning the second cleaner 400, and if so, controlling the second cleaner 400 to rotate from the second position to the empty position.

[0060] In summary, if Figure 1 As shown, when the second cleaner 400 is in the empty position, the filter screen 200 is not cleaned; then, as shown in FIG. Figure 2 As shown, when the second cleaner 400 is driven by the second motor to rotate counterclockwise to a certain angle, it can contact the filter 200. Driven by the first motor 52, the filter 200 slowly reciprocates clockwise, and the second cleaner 400 cleans the surface of the filter 200. The cleaned dust falls into the water collection tank 700 below, and the dust is washed away by the condensed water of the evaporator 600. In addition, in order to prevent the fallen dust from clogging the water collection tank 700, a dust collection box can also be provided under the second cleaner 400. The dust collection box can be cleaned after a period of time. At this time, the second cleaner 400 is in a state of cleaning the filter 200. When the second cleaner 400 finishes cleaning the filter 200, at this time, the mesh surface of the filter 200 and the first cleaner 300 are in contact with each other. Figure 1 In contrast, the filter 200 corresponds to the second cleaner 400, and the first cleaner 300 is located on the side of the filter 200 away from the second cleaner 400; at this time, the second motor drives the second cleaner 400 to rotate counterclockwise by a certain angle to return to the empty position, and at the same time, the filter 200 moves quickly (either clockwise or counterclockwise) to return to the empty position. Figure 1 ; after that, if Figure 3As shown, the first cleaner 300 is used to clean the large dust facing the second cleaner 400, that is, the second cleaner 400 is driven by the second motor to rotate clockwise or counterclockwise to a certain angle to contact the first cleaner 300 or the filter 200, and the first cleaner 300 is driven by the first motor 52 to perform slow counterclockwise reciprocating motion to comb the brush and clean the large dust remaining on the brush. Since the movement direction is counterclockwise and the second cleaner 400 is located between the filter 200 and the sump 700, after the large dust is brushed off, it can fall into the sump 700 with the help of gravity, so as to avoid the large dust from being raised and polluting the filter 200 or other internal parts of the air conditioner again; after the large dust is cleaned by the second cleaner 400, the filter 200 is driven by the first motor 52 to return to Figure 1 vacant space; Figure 4 As shown, the second cleaner 400 is driven by the second motor and rotates counterclockwise at a certain angle until it contacts the fins of the evaporator 600. The condensed water of the evaporator 600 is used to flush the second cleaner 400 to clean it. The high temperature of the evaporator 600 can also be used to dry the second cleaner 400 to avoid secondary contamination of the filter 200 by the dirty second cleaner 400. Finally, the second cleaner 400 returns to the cleaning position after completing the cleaning. Figure 1 of vacant space.

[0061] What those skilled in the art need to understand is that the first position refers to the position where the second cleaner 400 cleans the filter 200, and the first position is also the position where the first cleaner 300 dry-brushes the second cleaner 400, and the second position refers to the position where the second cleaner 400 is washed with condensed water from the evaporator 600, and the empty position is between the first position and the second position, which is the non-working position of the second cleaner 400.
