Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air duct cleaning device, method and air conditioner. Background Art

[0002] At present, wall-mounted air conditioners are suitable for installation in small indoor places such as bedrooms due to their compact structure. They do not occupy floor space and are convenient and beautiful. However, after long-term use, dust easily accumulates on the air duct and wind wheel inside the wall-mounted air conditioner. Due to the compact structure of the air conditioner, it is not convenient to clean. There is no device or method for automatically cleaning the air duct and wind wheel inside the air conditioner in the prior art. Summary of the invention

[0003] The main purpose of the present invention is to provide an air duct cleaning device, method and air conditioner, which are used to at least partially solve the above-mentioned technical problems.

[0004] To solve the above problems, the present invention provides an air duct cleaning device on one hand, characterized in that the device comprises: a cleaning member, which is arranged in the air duct, contacts the air duct wall, and extends along the arc of the air duct; a transmission assembly, connected to the first motor and the cleaning member, and is used to drive the cleaning member to move left and right in the air duct and between the two fixed ends of the wind wheel to clean the air duct and the wind wheel.

[0005] Thus, under the drive of the first motor, the transmission assembly drives the cleaning member disposed in the air duct and in contact with the air duct wall to move in the left and right directions to clean the air duct and the wind wheel. The air duct and the wind wheel of the air conditioner can be cleaned without disassembling the air conditioner, and the cleaning function can be automatically realized, which is convenient and fast, and improves the user experience.

[0006] Optionally, the transmission assembly includes: a slider connected to one end of the cleaning piece; a lead screw fixed on the air duct wall and connected to the first motor and parallel to the wind wheel rotation axis; the first motor drives the lead screw to rotate, and then drives the slider to move, driving the cleaning piece to move.

[0007] Optionally, the length of the lead screw is consistent with the length of the air duct or the wind wheel.

[0008] In this way, driven by the first motor, the lead screw rotates, thereby driving the slider connected to the lead screw to move along the length direction of the lead screw, that is, to translate in the length direction of the lead screw. At this time, the slider can drive the cleaning member to translate along the length direction of the lead screw. The length of the lead screw is consistent with the length of the air duct or the wind wheel, which can ensure that the moving distance of the cleaning member is long enough to achieve complete cleaning of the air duct or the wind wheel.

[0009] Optionally, a first groove is provided at the bottom of the air duct wall, and a baffle is provided at the opening of the first groove, and the baffle is connected to the second motor; the first groove and the baffle are used to accommodate the lead screw.

[0010] In this way, when the cleaning device is not used, the baffle is closed and the arrangement position of the lead screw will not hinder the normal operation of the air conditioner.

[0011] Optionally, a cavity is provided inside the baffle, and the cavity is communicated with the first groove and the fresh air cavity.

[0012] In this way, the fresh air fan and motor are started, and the fresh air chamber of the fresh air module forms a negative pressure. Because the baffle chamber is connected with the fresh air chamber, the baffle chamber also forms a negative pressure. When the dust wiped off by the cleaning member approaches the baffle, the dust will be carried into the baffle chamber by the airflow due to the connection between the baffle cavity and the first groove and the negative pressure formed in the baffle.

[0013] Optionally, the cleaning member is a brush of preset length, and the curvature of the brush is consistent with the curvature of the air duct, so as to facilitate cleaning of dust.

[0014] Optionally, the preset length is from the bottom of the air duct to a position where the cleaning member can contact the wind wheel.

[0015] In this way, the cleaning piece can clean the entire air duct, and the cleaning piece can contact the wind wheel to clean the wind wheel.

[0016] Optionally, a second groove is provided on the side wall of the air duct, and the second groove is used to receive the cleaning piece.

[0017] In this way, when the cleaning device is not used, the cleaning member will not hinder the normal operation of the air conditioner.

[0018] On the other hand, the present invention provides an air duct cleaning method, which includes: a first motor drives a cleaning piece to move left and right in the air duct and between two fixed ends of a wind wheel through a transmission assembly to clean the air duct, while the cleaning piece contacts the wind wheel to start the wind wheel to rotate, and the cleaning piece maintains contact with the wind wheel to clean the wind wheel; the fresh air motor is turned on to suck dust that slides down the air duct to near the baffle during cleaning into the internal cavity of the baffle to complete cleaning, and the cleaning piece is stored in the second groove.

[0019] The advantages of the air duct cleaning method are the same as those of the above-mentioned air duct cleaning device, which will not be described in detail here.

[0020] Another aspect of the present invention provides an air conditioner, comprising the air duct cleaning device described above.

[0021] The air conditioner has the same advantages as the above-mentioned air duct cleaning device, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the application purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] The embodiment of the present invention provides an air duct cleaning device, see below Figures 1 to 6 This embodiment is described in detail.

[0033] It should be noted that the directions or positional relationships indicated by "left", "right", etc., etc. of each structural component mentioned below refer to the orientations or positional relationships shown in the accompanying drawings; these positional relationships are only for the convenience and simplification of description, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] The air duct cleaning device comprises: a cleaning member 1, which is arranged in the air duct 2, contacts the air duct wall and extends along the arc of the air duct 2; a transmission assembly 4, which is connected to the first motor and the cleaning member 1, and is used to drive the cleaning member 1 to move left and right in the air duct 2 and between the two fixed ends of the wind wheel 3 to clean the air duct 2 and the wind wheel 3. The left and right movement here refers to Figure 1 The moving direction is shown by the double arrow N in FIG.

[0035] Thus, under the drive of the first motor, the transmission assembly drives the cleaning member disposed in the air duct and in contact with the air duct wall to move in the left and right directions to clean the air duct and the wind wheel. The air duct and the wind wheel of the air conditioner can be cleaned without disassembling the air conditioner, and the cleaning function can be automatically realized, which is convenient and fast, and improves the user experience.

[0036] In a feasible manner of this embodiment, the transmission assembly 4 includes: a slider 401, connected to one end of the cleaning member 1; a screw 402, fixed on the wall of the air duct and connected to the first motor, and parallel to the rotation axis of the wind wheel 3; the first motor drives the screw 402 to rotate, and then drives the slider 401 to move, driving the cleaning member 1 to move.

[0037] Driven by the first motor, the lead screw 402 rotates, thereby driving the slider 401 connected to the lead screw 402 to move along the length direction of the lead screw 402, that is, to translate along the length direction of the lead screw 402. At this time, the slider 401 can drive the cleaning member 1 to translate along the length direction of the lead screw 402. Since the lead screw 402 is usually fixed at both ends, in this embodiment, both ends are fixed in the first groove 5, the slider 401 can move from one end of the lead screw 402 to the other end. For example, when the lead screw 402 rotates in one direction, the slider 401 can move from the leftmost end to the rightmost end of the lead screw 402. When the lead screw 402 rotates in the opposite direction, the slider 401 can move from the rightmost end to the leftmost end of the lead screw 402. The length of the lead screw 402 is consistent with the length of the air duct 2 or the wind wheel 3, which can ensure that the moving distance of the cleaning member 1 is long enough to achieve complete cleaning of the air duct 2 or the wind wheel 3.

[0038] In a feasible manner of this embodiment, a first groove 5 is provided at the bottom of the air duct wall, and a baffle 6 is provided at the opening of the first groove 5, and the baffle 6 is connected to the second motor; the first groove 5 and the baffle 6 are used to accommodate the lead screw 402. A cavity is provided inside the baffle 6, and the cavity is communicated with the first groove 5 and the fresh air cavity.

[0039] The cavity is connected with the first groove 5 and the fresh air cavity, that is, a narrow slit is arranged near the first groove 5 on the baffle plate 6 to connect with the first groove 5, and the baffle plate 6 is connected with the fresh air module 10 through the pipeline 8, and the purification module 11 is required in the middle. When the fresh air blower and the motor are started, the fresh air cavity of the fresh air module forms a negative pressure, because the baffle cavity is connected with the fresh air cavity, the baffle cavity also forms a negative pressure, when the dust wiped off by the cleaning member approaches the baffle plate, due to the connection between the baffle cavity and the first groove and the negative pressure formed in the baffle plate, the dust will be carried into the baffle cavity by the airflow.

[0040] In addition, the cleaning member 1 is a brush of a preset length. The preset length is from the bottom of the air duct 2 to the position where the cleaning member 1 can contact the wind wheel. A second groove 7 is provided on the side wall of the air duct, and the second groove 7 is used to receive the cleaning member 1. That is, one end of the brush needs to be provided down to the bottom of the air duct 2 and up to the position where the brush can contact the wind wheel 3, so that while the brush cleans the entire air duct, it can contact the wind wheel 3 and clean the wind wheel 3. Moreover, the brush of the cleaning member can be set to have an arc that is consistent with the arc of the air duct 2. In this way, it can better fit the wall of the air duct, better clean the air duct, and also fit the arc of the wind wheel 3.

[0041] The second groove 7 should be connected to the first groove 5. The second groove 7 can be set on only one side wall of the air duct, such as the leftmost side wall of the air duct. It can also be set to two, for example, one second groove 7 is set on the leftmost side wall of the air duct and one second groove 7 is set on the rightmost side wall of the air duct. When cleaning is completed, the cleaning piece can be stored in one of the second grooves 7. Here, the air duct wall and the air duct side wall in the above text refer to the air conditioner base 9.

[0042] Embodiment 2

[0043] An embodiment of the present invention provides an air duct cleaning method, which includes the following steps S1-S3:

[0044] Step S1: Turn on the second motor to drive the baffle 6 to open; turn on the first motor, and the first motor drives the cleaning member 1 to move left and right in the air duct 2 and between the two fixed ends of the wind wheel 3 through the transmission assembly 4 to clean the air duct 2. At the same time, the cleaning member 1 contacts the wind wheel 3 to start the wind wheel 3 to rotate. The cleaning member 1 maintains contact with the wind wheel 3 to clean the wind wheel 3.

[0045] In this step, the first motor rotates forward, driving the lead screw 402 to move, and then the cleaning member 1 moves to the right along the width direction of the air duct through the slider 401; the air duct is cleaned for the first time; at the same time, the wind wheel 3 is started to run at a low speed; the wind wheel 3 touches the cleaning member 1, and the cleaning member 1 cleans the wind wheel 3; when the cleaning member 1 moves to the rightmost end, the first motor reverses, and the cleaning member 1 moves to the left along the width direction of the air duct 2; the air duct 2 is cleaned for the second time.

[0046] Step S2: Turn on the fresh air motor to suck the dust that slides down the air duct to the vicinity of the baffle 6 during cleaning into the internal cavity of the baffle 6.

[0047] When the fresh air fan and motor are started, negative pressure is formed in the fresh air cavity of the fresh air module. Since the baffle cavity is connected with the fresh air cavity, negative pressure is also formed in the baffle cavity. When the dust wiped off by the cleaning member approaches the baffle, the dust will be carried into the baffle cavity by the airflow due to the connection between the baffle cavity and the first groove and the negative pressure formed in the baffle.

[0048] Step S3: After cleaning is completed, the cleaning member 1 is stored in the second groove 7 .

[0049] When the cleaning member 1 returns to the second groove 7, the self-cleaning process of the air duct 2 and the wind wheel 3 ends; the first motor stops rotating, the second motor reverses, and drives the baffle 6 to close; the fresh air motor and the fan stop rotating; and the second motor stops rotating.

[0050] Embodiment 3

[0051] This embodiment provides an air conditioner, including the air duct cleaning device described in the first embodiment.

[0052] In summary, the present invention cleans the air duct and the wind wheel by using a transmission assembly to drive the cleaning member disposed in the air duct and in contact with the wall of the air duct to move in the left and right directions under the drive of the first motor. The air duct and the wind wheel of the air conditioner can be cleaned without disassembling the air conditioner, and the cleaning function can be automatically realized, which is convenient and fast, and improves the user experience. In addition, since a cavity is arranged inside the baffle, the cavity is connected to the first groove and the fresh air cavity. When the fresh air fan and the motor are started, a negative pressure is also formed in the baffle cavity. When the dust wiped off by the cleaning member approaches the baffle, the dust will be carried into the baffle cavity by the airflow, thereby realizing automatic dust collection.

[0053] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
