Referring to fig. 1, 2 and 3 together, the present application provides a range hood 100, the range hood 100 includes a body 10, a panel 20, a driving assembly 30 and a cleaning element 40, the panel 20 and the driving assembly 30 are both coupled to the body 10, the panel 20 has a shielding surface 21 facing away from the body 10, the cleaning element 40 is in transmission connection with the driving assembly 30, the cleaning element 40 has a pressing position pressing against the shielding surface 21 and an avoiding position where a projection in a plane of the shielding surface 21 is located outside the shielding surface 21; wherein the cleaning member 40 can move between the avoiding position and the pressing position under the action of the driving assembly 30.

In the conventional range hood 100, the cleaning element 40 is coupled to the body 10 and protrudes from the shielding surface 21, and the cleaning element 40 can scrape off the oil on the shielding surface 21 by moving on the shielding surface 21. However, since the dirt scraping member is always protruded from the shielding surface 21, the appearance of the range hood 100 is poor, and the user experience is low.

In the present application, when the shielding surface 21 is contaminated with oil, the driving assembly 30 drives the cleaning member 40 to switch from the avoiding position to the abutting position, so that the cleaning member 40 can clean the shielding surface 21; after the cleaning, the driving assembly 30 drives the cleaning member 40 to move from the abutting position to the avoiding position to prevent the cleaning member 40 from shielding the shielding surface 21, so that the range hood 100 has better aesthetic property and better user experience. It should be noted that the range hood 100 performs the smoking operation only when the cleaning member 40 is located at the avoiding position, and the range hood 100 stops smoking when the cleaning member 40 is located at the pressing position, so that the cleaning member 40 can be prevented from interfering with the smoking effect of the range hood 100.

It is worth mentioning that when the cleaning member 40 is in the pressing position, the cleaning member 40 can also move relative to the shielding surface 21 under the action of the driving assembly 30, so that the cleaning member 40 can clean the dirt on the shielding surface 21. Moreover, for promoting the cleaning effect of the shielding surface 21, a plurality of driving assemblies 30 and a plurality of cleaning pieces 40 can be further arranged, the plurality of driving assemblies 30 and the plurality of cleaning pieces 40 are in one-to-one correspondence, the corresponding driving assemblies 30 and the cleaning pieces 40 form a group of cleaning assemblies, the driving assemblies 30 in each group of cleaning assemblies drive the cleaning pieces 40 to clean the shielding surface 21, the areas of the shielding surfaces 21 cleaned by each cleaning piece 40 are different, and the sum of the areas cleaned by all the cleaning pieces 40 is equal to the area of the shielding surface 21, so that the shielding surface 21 can be cleaned comprehensively.

Specifically, the cleaning member 40 is configured to move in a translational and/or rotational manner between the retracted position and the pressing position upon actuation of the actuation assembly 30. The translational and/or rotational movement is simpler and the path of movement is shorter than the other movements, so that the cleaning element 40 can be simply and quickly repositioned.

Further, the cleaning member 40 has a transition position between the pressing position and the retracted position, the driving assembly 30 includes a rotary driving member 31, the rotary driving member 31 is in transmission connection with the cleaning member 40, and the rotary driving member 31 is configured to drive the cleaning member 40 to swing between the transition position and the pressing position around a connection point of the rotary driving member 31 and the cleaning member 40.

The range hood 100 is defined to have a reference surface, the shielding surface 21 is located in the reference surface, and the area of the reference surface is larger than that of the shielding surface 21. When the cleaning piece 40 is in the transition position, the cleaning piece 40 is positioned outside the shielding surface 21 and is pressed against the reference surface, and the projection of the cleaning piece 40 in the reference surface is positioned outside the shielding surface 21, so that the cleaning piece 40 can be directly and quickly switched to the pressing position by swinging a small angle in a small range, and the shielding surface 21 can be conveniently cleaned; when the cleaning piece 40 is in the abutting position, under the action of the driving assembly 30, the cleaning piece 40 abuts against the shielding surface 21, the cleaning piece 40 can move on the shielding surface 21, and under the action of the abutting force, a large friction force exists between the cleaning piece 40 and the shielding surface 21, so that the shielding surface 21 can be cleaned by the cleaning piece 40 conveniently.

Through the swing of the rotary driving member 31 driving the cleaning piece 40, compared with the way that the driving assembly 30 drives the cleaning piece 40 to do linear motion or curvilinear motion, the connection way of the cleaning piece 40 and the driving assembly 30 is simpler, and under the condition that the position of the driving assembly 30 is not changed, the cleaning piece 40 can move around the connection point of the driving assembly 30 and the cleaning piece 40, so that the driving assembly 30 can be prevented from shielding the shielding surface 21, and the cleaning piece 40 can more comprehensively clean the shielding surface 21.

Referring to fig. 4, specifically, the pressing position includes a first limit position and a second limit position, the first limit position is a position at which the cleaning member 40 swings from the transition position to an instant of pressing against the shielding surface 21, the second limit position is a position at which the rotary driving member 31 drives the cleaning member 40 to have a maximum swing angle relative to the first limit position, and after the cleaning member 40 is switched from the transition position to the pressing position by the rotary driving member 31, the cleaning member 40 swings back and forth between the first limit position and the second limit position to clean the shielding surface 21.

In particular, during the oscillation of the cleaning element 40 from the transition position to the first extreme position, the cleaning element 40 does not clean the shielding surface 21; during the pivoting of the cleaning element 40 between the first and the second limit position, the cleaning element 40 can clean the shielding surface 21.

In addition, in order to further reduce the shielding of the driving assembly 30 on the shielding surface 21, when the driving assembly 30 is disposed on the machine body 10, it is preferable that the driving assembly 30 is located outside the shielding surface 21, so that the driving assembly 30 does not shield the shielding surface 21 at all, thereby facilitating the cleaning piece 40 to clean the shielding surface 21 comprehensively.

Referring to fig. 5, the driving assembly 30 further includes a translational driving member 32, the rotational driving member 31 is drivingly connected between the translational driving member 32 and the cleaning member 40, and the translational driving member 32 is configured to drive the rotational driving member 31 to slide the cleaning member 40 between the retracted position and the transition position. Specifically, in the process that the translational driving element 32 drives the rotational driving element 31 to drive the cleaning element 40 to slide from the avoidance position to the transition position, the cleaning element 40 gradually approaches to the plane where the shielding surface 21 is located along the sliding direction of the cleaning element, and in the process that the translational driving element 32 drives the rotational driving element 31 to drive the cleaning element 40 to move from the transition position to the avoidance position, the cleaning element 40 gradually leaves away from the plane where the shielding surface 21 is located. Through setting up translation driving piece 32, translation driving piece 32 drives rotatory driving piece 31 and drives washing piece 40 rectilinear sliding to make washing piece 40 can realize the position fast and switch over. Alternatively, the translation drive 32 may be a powered push rod.

Referring to fig. 2 and 3 again, the range hood 100 further includes a conveying assembly, the conveying assembly includes a power member (not shown) and a storage member 50, the storage member 50 has a storage chamber for storing the cleaning agent, and the power member is configured to provide a driving force for driving the cleaning agent in the storage chamber to flow to the shielding surface 21. When the cleaning piece 40 is in the abutting position and moves on the shielding surface 21, the power piece is started and drives the cleaning agent in the storage cavity to flow to the shielding surface 21, and the cleaning agent can soften or dissolve dirt, so that the abutting piece can effectively and quickly remove the dirt in the process of abutting against and moving on the shielding surface 21, and the shielding surface 21 has a better cleaning effect. Specifically, to prevent the power member from shielding the shielding surface 21, the power member may be disposed on a surface of the machine body 10 except for a plane where the shielding surface 21 is located. Alternatively, the power member may be a drive pump.

Furthermore, the cleaning element 40 has a plurality of pores (not shown), and when the cleaning element is in the pressing position, the driving force provided by the power element can drive the cleaning agent in the storage chamber to flow to the shielding surface 21 through the plurality of pores. Specifically, the micropores are uniformly distributed on the cleaning element 40, and the cleaning agent flows toward the shielding surface 21 under the action of the power element, so that in the process of moving the pressing element on the shielding surface 21, dirt on the contact area between the pressing element and the shielding surface 21 can be cleaned, softened or dissolved, and the shielding surface 21 has a good cleaning effect.

Furthermore, the cleaning member 40 has a rigid portion 41 and a flexible portion 42 coupled to the rigid portion 41, the rigid portion 41 is in transmission connection with the driving assembly 30, and the flexible portion 42 is provided with a plurality of micro-holes; when the flexible portion 42 is in the pressing position, the flexible portion 42 presses against the shielding surface 21, and the cleaning agent in the storage chamber flows to the shielding surface 21 through the plurality of micro holes on the flexible portion 42. The rigid portion 41 is used for supporting the flexible portion 42, the flexible portion 42 is relatively soft, specifically, the flexible portion 42 can be a sponge, and in the process that the flexible portion 42 is pressed against the pressing surface, because the plurality of micropores are formed in the flexible portion 42, in the process that the flexible portion 42 is in contact with the shielding surface 21, it can be ensured that dirt on the area where the flexible portion 42 is in contact with the shielding surface 21 can be cleaned, softened or dissolved, so that a better cleaning effect is achieved. Moreover, since the flexible portion 42 is also soft, the flexible portion 42 can be prevented from scratching the shielding surface 21 when the flexible portion 42 is pressed against the shielding surface 21.

Specifically, the rigid portion 41 and the flexible portion 42 may be detachably connected, or the rigid portion 41 and the rotary driving member 31 may be detachably connected, so that, after the flexible portion 42 is soiled due to long-term use, the flexible portion 42 may be detached from the rigid portion 41, or the rigid portion 41 may be detached from the rotary driving member 31, so as to facilitate cleaning of the flexible portion 42.

Specifically, the range hood 100 further includes a controller (not shown), a switch (not shown), and a pipe structure (not shown), wherein the pipe structure is connected between the storage chamber and the plurality of micro holes, the switch is coupled to the pipe structure and electrically connected to the controller, and the controller is configured to control the switch to be turned on when the cleaning member 40 is located at the pressing position. Specifically, when the cleaning piece 40 swings to the abutting position, the controller controls the switch to be turned on so that the cleaning agent in the storage cavity can flow onto the shielding surface 21, and when the cleaning piece 40 is located at the avoiding position, the controller controls the switch to be turned off so that the cleaning agent in the storage cavity is prevented from flowing out and being wasted. Therefore, by arranging the controller, the switch and the pipeline structure, the cleaning agent in the storage cavity can be automatically sprayed out or automatically stopped to be sprayed out, so that the range hood 100 can be automatically cleaned.

Specifically, the controller is further electrically connected to the translational driving element 32 and the rotational driving element 31 of the driving assembly 30, when a user wants to clean the range hood 100, or the range hood 100 automatically detects that the shielding surface 21 is too dirty, the controller controls the translational driving element 32 and the rotational driving element 31 in the driving assembly 30 to sequentially start up, so that the cleaning element 40 can slide from the avoidance position to the transition position, and then swing from the transition position to the first limit position, further, the rotational driving element 31 drives the cleaning element 40 to swing back and forth between the first limit position and the second limit position to clean the shielding surface 21, and when the cleaning element 40 swings to the first limit position under the action of the rotational driving element 31, the controller controls the switch to be turned on, so that the cleaning agent can be sprayed onto the shielding surface 21. After the cleaning process is finished, the controller firstly controls the switch to be turned off, and then controls the cleaning piece 40 to move to the avoiding position through the first limit position and the transition position in sequence, so that the whole cleaning process is finished.

The pipe structure penetrates through the driving assembly 30 and the rigid part 41 of the cleaning piece 40 in sequence along the flowing direction of the cleaning agent, and is hidden in the driving assembly 30 and the rigid part 41. Specifically, part of or all of the micropores on the flexible portion 42 are communicated with the pipeline structure, and the cleaning agent in the storage chamber can flow into the micropores communicated with the pipeline structure through the pipeline structure, and then can flow to the shielding surface 21 through the micropores. The duct structure sequentially penetrates through the driving assembly 30 and the rigid portion 41, so that the duct structure can be hidden, and the aesthetic property of the range hood 100 can be further improved.

Referring to fig. 2 again, when the cleaning element 40 is located at the retracted position, the driving assembly 30 and the cleaning element 40 are both supported on the top end surface 11 of the machine body 10. Generally, the top end surface 11 of the machine body 10 is opposite to the ground in the vertical direction and is spaced from the ground, and the position is higher than the ground, so when the cleaning member 40 is located at the avoiding position, the driving assembly 30 and the cleaning member 40 are both carried on the top end surface 11 of the machine body 10, and are also higher than the ground, and the driving assembly 30 and the cleaning member 40 can be better hidden, so that the range hood 100 has better aesthetic property.

The range hood 100 further includes a fixing base 60, the fixing base 60 is fixed on the machine body 10, and the translational driving element 32 in the driving assembly 30 is fixed on the fixing base 60 so as to be fixed on the machine body 10 through the fixing base 60. By providing the mounting base 60, the translational drive member 32 may be conveniently mounted.

Next, the cleaning process of the entire range hood 100 will be described.

After the range hood 100 stops smoking, when dirt exists on the shielding surface 21, the controller controls the translational driving element 32 to extend, so that the cleaning element 40 can slide from the avoiding position to the transition position. Then, the rotary driving member 31 drives the cleaning member 40 to swing so that the rotary driving member 31 can swing from the transition position to the first limit position, and then the rotary driving member 31 continues to move, and the cleaning member 40 can swing back and forth between the first limit position and the second limit position to clean the shielding surface 21. It is worth mentioning that when the rotary driving member 31 swings from the transition position to the first limit position, the controller controls the switch to be turned on, and the cleaning agent in the storage chamber can flow to the shielding surface 21. After the cleaning process is finished, the controller controls the switch to be turned off, controls the rotary driving part 31 to drive the cleaning part 40 to swing from the current position to the transition position through the first limit position, and controls the translational driving part 32 to drive the cleaning part to contract reversely, so that the cleaning part 40 can slide to the avoidance position, and the whole cleaning process is finished.

In the range hood 100, when the shielding surface 21 is contaminated with oil, the driving assembly 30 drives the cleaning member 40 to switch to the abutting position, so that the cleaning member 40 can clean the shielding surface 21; after the cleaning, the driving assembly 30 drives the cleaning member 40 to move to the avoiding position to prevent the cleaning member 40 from shielding the shielding surface 21, so that the range hood 100 has better aesthetic property and better user experience.
