Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly relates to a cleaning component, an air conditioner and an air conditioner cleaning method. Background Art

[0002] In general household air conditioners, most of the used air conditioners are wall-mounted, and the indoor unit is generally suspended indoors. During the use of the air conditioner, the indoor unit inhales the indoor air and then passes through a condenser, an evaporator, etc. to achieve the purpose of reducing the air temperature, and then sends the low-temperature gas back to the room. During the process of inhaling air, since there are many dust and bacteria in the air, they will enter the air conditioner together with the air. Only a small amount of impurities will return to the room with the low-temperature gas, and most of the dust and bacteria will be adsorbed on the evaporator, filter screen and air duct inside the air conditioner. Coupled with the action of the condensate water inside the air conditioner, more stains and more bacteria will grow on the internal evaporator and filter screen.

[0003] In the prior art, generally, to clean an air conditioner, professional personnel are required to completely disassemble the air conditioner to clean the internal components of the air conditioner, so as to achieve the effect of air conditioner cleaning. There are special cleaning devices for the filter screen and evaporator on the market, but they all have certain limitations. For the cleaning of the filter screen, most of the methods adopted on the market are brush cleaning and collecting with a dust collection box.

[0004] Subsequent processing of the dust collection box needs to be carried out by the user, which not only is not conducive to the user experience, but also brings certain risks to the user.

[0005] In addition, for the cleaning of the evaporator, there is a self-cleaning technology for the evaporator on the market, which adsorbs dust by frosting the evaporator in the cooling mode to achieve the cleaning of the dirt on the evaporator. The evaporator needs to reach a certain temperature to frost in the cooling mode, which is not conducive to the user experience. If the user asks professional personnel to disassemble and clean the air conditioner, the user not only needs to pay relevant fees, but also needs to cooperate with time. Summary of the Invention

[0027] The water guide plate can be installed in the machine body in a guided manner and the water guide plate can be controlled and guided according to the operating state of the cleaning component;

[0028] When the cleaning component is in the open state, the bottom end of the water guide plate can be controlled to move toward one side of the drainage hole and block the air outlet of the machine body, and the water guide plate is in the closed state at this time;

[0029] When the cleaning component changes from an open state to a closed state, the bottom end of the water guide plate can be controlled to move toward a side away from the drainage hole and remove the obstruction to the air outlet of the machine body. At this time, the water guide plate is in an open state.

[0030] In the above technical solution, the air conditioner is a wall-mounted air conditioner.

[0031] A third aspect of an embodiment of the present invention provides an air conditioner cleaning method, which is applied to the air conditioner mentioned above. The cleaning method comprises:

[0032] The dust content value m in the machine body is obtained and compared with the first preset dust content value m1, and whether to start the cleaning component is selected according to the comparison result.

[0033] In the above technical solution, the method of selecting whether to start the cleaning component according to the comparison result includes:

[0034] If the dust content value m in the machine body is greater than the first preset dust content value m1, an alarm is issued to the user to remind the user whether to start the cleaning mode.

[0035] In the above technical solution, if the user chooses to start the cleaning mode, it is further compared whether the dust content value m in the machine body is greater than the second preset dust content value m2;

[0036] If the first preset dust content value m1 is less than the dust content value m in the machine body and less than the second preset dust content value m2, step S1 is executed: the water inlet valve and the first driving motor in the cleaning component are turned on, the water outlet of the cleaning water pipe is directly facing the filter screen, and the first driving motor drives the cleaning water pipe to move horizontally to perform a reciprocating cleaning of the internal parts of the machine body;

[0037] If the dust content value m in the machine body is greater than the second preset dust content value m2, then step S2 is executed: the water inlet valve, the first drive motor, and the second drive motor in the cleaning assembly are turned on, the second drive motor drives the cleaning water pipe to rotate a preset angle so that the water outlet of the cleaning water pipe is inclined towards the filter screen, and the first drive motor drives the cleaning water pipe to translate to perform a reciprocating cleaning of the internal parts of the machine body.

[0038] In the above technical solution, during the execution of step S2, the preset angles at which the second drive motor drives the cleaning water pipe to rotate include a first preset angle and a second preset angle;

[0039] When the cleaning water pipe moves towards the side of the micro switch, the second drive motor drives the cleaning water pipe to rotate clockwise by the first preset angle;

[0040] When the cleaning water pipe moves towards the side away from the micro switch, the second drive motor drives the cleaning water pipe to rotate counterclockwise by the second preset angle;

[0041] Where the second preset angle = 2 * the first preset angle.

[0042] In the above technical solution, after the first drive motor drives the cleaning water pipe to translate to perform a back-and-forth cleaning of the filter screen and the evaporator, the dust content value m in the machine body is obtained again and compared with the first preset dust content value m1 and the second preset dust content value m2;

[0043] If the dust content value m in the machine body is less than the first preset dust content value m1, the cleaning assembly is turned off and the cleaning mode ends;

[0044] If the first preset dust content value m1 < the dust content value m in the machine body < the second preset dust content value m2, then step S1 is executed;

[0045] If the dust content value m in the machine body is greater than the second preset dust content value m2, then step S2 is executed.

[0046] In the above technical solution, the cleaning method further includes:

[0047] After the execution of step S2, if the dust content value m in the machine body is less than the first preset dust content value m1 or the first preset dust content value m1 < the dust content value m in the machine body < the second preset dust content value m2, the second drive motor also drives the cleaning water pipe to rotate clockwise by a third preset angle;

[0048] Where the third preset angle = the first preset angle.

[0049] In the above technical solution, if the dust content value m in the machine body is greater than the first preset dust content value m1, the water guide plate can be controlled to be in a closed state;

[0065] Here, exemplary embodiments will be described in detail, and examples thereof 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 invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0066] For currently existing air conditioners, it is not convenient to clean components such as the filter screen and evaporator inside the body. In the embodiments of the present invention, a cleaning assembly capable of driving a cleaning water pipe to reciprocate is provided. When it is installed on an air conditioner body, it can clean the components in the air conditioner body, so that users can clean the air conditioner without relying on professional personnel.

[0067] The following combines the attached Figures 1-10 The technical solutions of this embodiment will be elaborated in detail. Without conflict, the following embodiments and examples can be combined with each other.

[0068] Embodiment

[0069] As Figures 1-6 shown, on the one hand, an embodiment of the present invention provides a cleaning assembly for cleaning an air conditioner, including:

[0070] A support frame 1, which encloses a rectangular notch;

[0071] A cleaning water pipe 2, installed in the rectangular notch and capable of being driven to reciprocally translate along the length direction of the rectangular notch;

[0072] Wherein a plurality of cleaning water outlets 21 are provided at the bottom of the cleaning water pipe 2 along the width direction of the rectangular notch.

[0073] The cleaning water pipe 2 in the embodiment of the present invention can be driven to reciprocate in the support frame 1. When installed on an air conditioner, it can clean components such as the filter screen 8 and evaporator 9 inside the air conditioner.

[0074] It should be noted that the "rectangle" mentioned in the embodiments of the present application does not require a geometric concept defined purely mathematically. As long as it has two parallel sides up and down, the width of the channel is restricted by these two sides, and the length of the channel is greater than the width of the channel, so that the cleaning water pipe 2 can be translated along the length of the channel.

[0075] Specifically, the cleaning assembly further includes:

[0076] A driving part, where the driving part includes a first driving part and a second driving part;

[0077] The first driving part is configured to drive the cleaning water pipe 2 to reciprocally translate along the length direction of the rectangular notch;

[0078] The second driving part is configured to change the water outlet angle of the cleaning water pipe 2.

[0079] In the embodiments of the present invention, by setting the second driving part, the water outlet angle of the cleaning water pipe 2 can be changed when there is more dust in the air conditioner, thereby improving the cleaning effect on the interior of the air conditioner.

[0080] More specifically, the first driving part includes a conveyor belt arranged along the length direction of the rectangular notch and a first driving motor 4 as the driving source of the conveyor belt. When the conveyor belt is driven, it drives the cleaning water pipe 2 to translate along the length direction of the rectangular notch;

[0081] The second driving part includes a second driving motor 5. The second driving motor 5 can drive the cleaning water pipe 2 to rotate to change the water outlet angle of the cleaning water pipe 2.

[0082] When there is more dust in the air conditioner, the second driving motor 5 can drive the cleaning water pipe 2 to rotate a preset angle, thereby changing the water outlet direction of the cleaning water port 21 at the bottom of the cleaning water pipe 2, so that the cleaning water port 21 discharges water obliquely, thereby improving the cleaning effect on the interior of the air conditioner. At the same time, when the cleaning water pipe discharges water obliquely, it can also increase the cleaning area, thereby further improving the cleaning effect.

[0083] In any of the above embodiments, grooves are provided on both side wall surfaces in the length direction of the support frame 1. The conveyor belt is installed in the grooves on both sides of the support frame. Driven by the first driving motor 4, it starts to drive. The second driving motor 5 is fixedly installed on the surface of the conveyor belt and placed in the groove. Specifically, the second driving motor 5 can be fixedly installed on the surface of the conveyor belt by bonding, so that when the conveyor belt is driven, the cleaning water pipe 2 can be driven to translate through the second driving motor 5.

[0084] It should be noted that when the first drive motor 4 controls the transmission belt during transmission, it only controls the transmission belt to run a certain distance. When the second drive motor 5 follows the movement of the transmission belt, it only makes a displacement in the horizontal direction, so that there will be no problem of interference between the second drive motor 5 and other components during the movement process.

[0085] In any of the above embodiments, a microswitch 6 is provided on the wall surface in the width direction of the support frame 1. When the cleaning water pipe 2 translates along the length direction of the support frame 1, it can contact the microswitch 6, and the translation direction of the cleaning water pipe 2 can be changed when the cleaning water pipe 2 contacts the microswitch 6.

[0086] On the other hand, an air conditioner as shown in Figures 7-9 is also provided in an embodiment of the present invention, including a body 7 and the cleaning assembly mentioned above;

[0087] An evaporator 9 and a filter screen 8 are provided in the body 7. The filter screen 8 is arranged above the evaporator 9. An installation position is provided at the top of the body 7. The cleaning assembly is installed at the installation position, and after installation, the cleaning water outlet in the cleaning assembly faces the filter screen 8 to clean the filter screen 8, the evaporator 9 and other parts in the body when the cleaning assembly operates.

[0088] In any of the above embodiments, the air conditioner further includes:

[0089] A controller and a dust content sensor, where the dust content sensor is used to detect the dust content in the body 7, and the controller can control the operation of the first drive motor 4 and / or the second drive motor 5 according to the dust content detected by the dust content sensor.

[0090] In any of the above embodiments, a water guide plate 10 is provided inside the body 7, and a drain hole 11 is provided at the bottom of the body 7;

[0091] When the cleaning assembly is turned on, the cleaning water after cleaning the filter screen and the evaporator is drained from the drain hole 11 after being guided by the water guide plate 10.

[0092] Specifically, the cleaning water pipe 2 is directly externally connected to a water source and is provided with a water inlet valve. When the water inlet valve is opened, high-pressure water flow directly cleans the inside of the air conditioner through the cleaning water outlet 21 at the bottom of the cleaning water pipe 2. When the first drive motor 4 is started, the cleaning water pipe 2 makes a reciprocating movement driven by the transmission belt, and the high-pressure water flow cleans the internal parts (such as the filter screen 8, the evaporator 9, etc.) of the air conditioner as the cleaning water pipe 2 moves. The dust in the air conditioner is washed by the water flow and flows along with the water flow. The water guide plate 10 guides the water flow into the water channel provided on the bottom shell of the body 7 and flows out from the drain hole 11 and flows to the outside. The internal parts of the air conditioner are cleaned.

[0093] In any of the above embodiments, the water guide plate 10 and the drain hole 11 are arranged on both sides of the bottom air outlet 12 of the machine body 7;

[0094] Among them, the water guide plate 10 can be installed in the machine body 7 in a guided manner and the water guide plate 10 can be controlled to be guided according to the operating state of the cleaning component;

[0095] Specifically, when the cleaning component is in the on state, the bottom end of the water guide plate 10 can be controlled to move towards one side of the drain hole 11 and block the air outlet 12 of the machine body 7. At this time, the water guide plate 10 is in the closed state;

[0096] When the cleaning component changes from the on state to the off state, the bottom end of the water guide plate 10 can be controlled to move towards the side away from the drain hole 11 and release the block of the air outlet 12 of the machine body 7. At this time, the water guide plate is in the open state.

[0097] Thus, it is avoided that the water guide plate 10 affects the normal air outlet of the air conditioner when it does not conduct water.

[0098] In any of the above embodiments, the air conditioner mentioned above is a wall-mounted air conditioner, and the cleaning component is installed on the indoor unit of the air conditioner.

[0099] On the other hand, the embodiment of the present invention also provides an air conditioner cleaning method as Figure 10 shown, which is applied to the air conditioner mentioned above. The cleaning method of the air conditioner includes:

[0100] Obtain the dust content value m in the machine body and compare it with the first preset dust content value m1, and select whether to start the cleaning component according to the comparison result.

[0101] In the above cleaning method, the method of selecting whether to start the cleaning component according to the comparison result includes:

[0102] If the dust content value m in the machine body > the first preset dust content value m1, an alarm prompt is sent to the user to remind the user whether to start the cleaning mode.

[0103] Specifically, if the user selects to start the cleaning mode, further compare whether the dust content value m in the machine body is greater than the second preset dust content value m2;

[0104] If the first preset dust content value m1 < the dust content value m in the machine body < the second preset dust content value m2, then execute step S1: the water inlet valve and the first drive motor 4 in the cleaning component are turned on, and the cleaning water outlet 21 of the cleaning water pipe 2 is facing the filter screen 8, and the first drive motor 4 drives the cleaning water pipe 2 to translate to perform a reciprocating cleaning on the filter screen 8 and the evaporator 9;

[0105] If the dust content value m in the machine body is greater than the second preset dust content value m2, then step S2 is executed: the water inlet valve, the first drive motor 4, and the second drive motor 5 in the cleaning assembly are turned on, and the second drive motor 5 drives the cleaning water pipe 2 to rotate a preset angle so that the water outlet of the cleaning water pipe 2 is inclined towards the filter screen 8, and the first drive motor 4 drives the cleaning water pipe 2 to translate to perform a reciprocating cleaning of the filter screen 8 and the evaporator 9.

[0106] During the execution of step S2, the preset angles at which the second drive motor 5 drives the cleaning water pipe 2 to rotate include a first preset angle and a second preset angle;

[0107] When the cleaning water pipe 2 moves towards the side of the micro switch 6, the second drive motor 5 drives the cleaning water pipe 2 to rotate clockwise by the first preset angle;

[0108] When the cleaning water pipe 2 moves towards the side away from the micro switch 6, the second drive motor 5 drives the cleaning water pipe 2 to rotate counterclockwise by the second preset angle;

[0109] Where the second preset angle = 2 * the first preset angle.

[0110] In the above cleaning method, after the first drive motor 4 drives the cleaning water pipe 2 to translate to perform a back-and-forth cleaning of the filter screen 8 and the evaporator 9, the dust content value m in the machine body is obtained again and compared with the first preset dust content value m1 and the second preset dust content value m2;

[0111] If the dust content value m in the machine body is less than the first preset dust content value m1, the cleaning assembly is turned off and the cleaning mode ends;

[0112] If the first preset dust content value m1 < the dust content value m in the machine body < the second preset dust content value m2, then step S1 is executed;

[0113] If the dust content value m in the machine body is greater than the second preset dust content value m2, then step S2 is executed.

[0114] In the above cleaning method, the cleaning method further includes:

[0115] After the execution of step S2, if the dust content value m in the machine body is less than the first preset dust content value m1 or the first preset dust content value m1 < the dust content value m in the machine body < the second preset dust content value m2, the second drive motor 5 also drives the cleaning water pipe 2 to rotate clockwise by a third preset angle;

[0116] Where the third preset angle = the first preset angle.

[0117] In the above cleaning method, if the dust content value m in the machine body is greater than the first preset dust content value m1, the water guide plate 10 can be controlled to be in a closed state;

[0118] When the dust content value m in the machine body is less than the first preset dust content value m1, the water guide plate 10 can be controlled to be in an open state.

[0119] Specifically, as Figure 10 shown, when the dust content inside the air conditioner exceeds the first preset dust content value m1, the air conditioner will issue an alarm prompt. This alarm prompt can be the appearance of a specific symbol on the indoor unit display or a form of sound and light alarm to remind the user that the dust content of the indoor unit has reached an unqualified value and it is necessary to start the cleaning mode to clean the indoor unit.

[0120] After the user starts the cleaning mode, further determine whether the dust content in the indoor unit is greater than the second preset dust content value m2, and select to start the first drive motor 4 alone or start the first drive motor 4 and the second drive motor 5 simultaneously according to the judgment result, that is, select to execute step S1 or step S2 in the above cleaning method.

[0121] When the system determines to execute step S1 or step S2, the water guide plate 10 is started under the action of a water guide plate motor (not shown in the figure); at the same time, the water inlet valve of the water inlet assembly is opened, and water automatically enters at the cleaning water pipe. The conveyor belt drives the cleaning water pipe 2 to translate toward one side of the micro switch 6, and high-pressure water flow cleans the components in the indoor unit through the cleaning water outlet 21 at the bottom of the cleaning water pipe.

[0122] After the cleaning water pipe 2 touches the micro switch 6, control the first drive motor 4 to reverse and drive the conveyor belt to move back, so as to realize the reciprocating cleaning of the indoor unit of the air conditioner.

[0123] The cleaned cleaning water is introduced into the water channel under the action of the water guide plate 10, passes through the drain hole 11, and the drain pipe is connected to the drain hole 11 to drain the cleaning water to the outside. The cleaning water pipe 2 returns to its original position under the drive of the conveyor belt, and the dust content sensor re-detects the dust content inside the machine body. When it is detected that the dust content reaches the qualified value, the cleaning mode will be automatically closed; if it does not reach the qualified value, steps S1 or S2 will be started again until the dust content in the indoor unit reaches the qualified value (that is, the dust content in the indoor unit is less than the first preset dust content).
