[ detailed description ] of the utility model

For the purposes of making the objects, aspects and advantages of the present application more apparent, the present application will be further described with reference to the drawings and preferred embodiments.

An embodiment of a range hood according to the present application, referring to fig. 1, includes a housing member 10 and a panel 20, wherein the panel 20 is detachably mounted to the housing member 10. The back of the panel 20 is provided with a relief portion 42 including a relief space, the housing member 10 is provided with a first mounting member 30, and the first mounting member 30 is provided with an elastic fastener 50. The mounting direction of the panel 20 is the X direction, wherein the X direction is the horizontal direction of the plane in which the panel 20 is located.

It should be noted that the plane of the panel 20 refers to the plane of the panel 20 facing the user or the kitchen range, and is generally the largest area in the daily use environment of the range hood. For clarity, fig. 1 shows an XYZ coordinate system in which the horizontal direction X, the normal direction Y and the vertical direction Z, which are perpendicular to each other, of the plane in which the panel 20 is located in a conventional state of the range hood are schematically shown by arrows.

As shown in fig. 2, during the actual installation of the panel 20, the relief portion 42 slides in the X direction, and presses the elastic fastener 50 to elastically deform. As shown in fig. 3, when the relief space reaches the elastic fastener 50, the elastic fastener 50 is no longer pressed by the relief portion 42 to generate elastic recovery, and is locked in the relief space, and at this time, the displacement of the panel 20 in the X direction is limited by the cooperation of the relief space and the elastic fastener 50. Thus, by the engagement of the connecting portion 40 and the elastic fastener 50, the panel 20 can be positioned in the horizontal direction without requiring a connection means such as a screw at the time of installation.

As shown in fig. 4, the back surface of the panel 20 is provided with a connecting portion 40, and a relief portion 42 is provided at the connecting portion 40; the first mounting member 30 is also provided with a catch. The connecting portion 40 cooperates with the retaining portion to define a displacement of the panel 20 in a Z direction, wherein the Z direction is a vertical direction of the plane in which the panel 20 is located. Specifically, as shown in fig. 5, the first mounting member 30 has an L-shaped cross section in the X-direction, and is composed of a pair of first and

second laths

31 and 32 perpendicular to each other. When the first mounting member 30 is fixed to the housing member 10, as shown in fig. 6, the first slat 31 is in a horizontal direction, and the second slat 32 is in a vertical direction. The elastic fastener 50 is disposed on the first slat 31, and the elastic fastener and the first slat may be connected by a screw, or may be integrally formed, and the specific manner is not limited. The catch is provided on the second slat 32, and in particular, the catch may be an opening in the second slat 32.

As shown in fig. 4 and 7, the connecting portion 40 includes a connecting portion body, and a first clamping plate 41 and a relief portion 42 provided on the connecting portion body. The connecting part body is arranged on the back surface of the panel 20, and one side of the connecting part body far away from the panel 20 is provided with a first clamping plate 41 and a abdication part 42. The catch cooperates with the first clamping plate 41 to limit displacement of the panel 20 in the Z direction. The relief space is disposed on the relief portion 42, and cooperates with the elastic fastener 50 to limit displacement of the panel 20 in the X direction. Specifically, the catch may include a first opening 321 and a second opening 322. The first opening 321 is disposed on the second lath 32 at a position corresponding to the first clamping plate 41, and is disposed along the X direction, and the width in the Z direction is just adapted to the thickness of the first clamping plate 41, so as to limit the displacement of the panel 20 in the Z direction; as shown in fig. 7, the first clamping plate 41 is formed at a position close to the connecting plate body, the width of the clamping slot 411 is equal to the thickness of the second lath 32, and the matching of the clamping slot 411 and the first opening 321 limits the displacement of the panel 20 in the Y direction. The second opening 322 is disposed on the second slat 32 at a position corresponding to the abdication portion 42, and is configured to allow the abdication portion 42 to pass through during the installation process of the panel 20, so as to cooperate with the elastic fastener 50.

Thus, through the cooperation of the connecting portion 40, the elastic fastener 50 and the clamping portion, the panel 20 and the shell member 10 realize detachable installation, and compared with the traditional screw fixation, the panel is convenient and quick and does not influence the appearance.

A. First embodiment:

in one embodiment, as shown in fig. 8, the elastic fastener 50 is a spring latch 51, and the spring latch 51 includes a pin body 511, a latch rod 512, a stopper plate 513, and a spring 514. The top surface of the pin body 511 is provided with a through hole 5111, and the insertion rod 512 is engaged with the through hole 5111 and penetrates the pin body 511. A stop plate 513 is provided on the plunger 512 and is located within the pin 511. The spring 514 is sleeved on the plunger 512, and two ends of the spring 514 respectively abut against the inner wall of the pin body 511 and the limiting plate 513. The end of the insert rod 512 away from the limiting plate 513 is provided with a handle 515, so that a user can conveniently lift the insert rod 512 to be separated from the abdication space when the panel 20 is detached. Specifically, the pin body 511 is in a shape of a Chinese character 'ji', and includes two end surfaces and a top surface, and the two end surfaces are respectively provided with a connecting hole. The first slat 31 is also provided with a connection structure at a position corresponding to the connection hole, so that the pin body 511 and the first slat 31 may be directly connected by means of a screw or the like. The through hole 5111 is a D-shaped through hole, and the insertion rod 512 includes a first rod 5121 and a second rod 5122. The first shaft 5121 has a D-shaped cross section, and is engaged with the through hole 5111 and penetrates the top surface of the pin body 511, and simultaneously, the rotation of the plunger 512 is prevented, thereby preventing the damage to the panel 20 caused by the random rotation of the handle 515 during the installation process. The second shaft 5122 is located in the pin 511 and penetrates the first slat 31 as shown in fig. 8. The second rod 5122 has a circular cross section, and cannot pass through the through hole 5111, so that the maximum distance for pulling up the handle 515 can be limited, and deformation caused by excessive compression of the spring 514 and excessive stress on the handle 515 can be avoided.

As shown in fig. 7, the relief portion 42 includes a plate 421 and a flange 422, and the relief space is disposed on the plate 421. The plate 421 includes adjacent first and second sides, the first side is adjacent to the connecting portion body, and the second side is adjacent to the flange 422. During the installation of the panel 20, the flange 422 and the plate 421 slide against the insert rod 512, so that the spring 514 is elastically deformed. Specifically, during the installation process, the flange 422 is in sliding contact with the insert rod 512, the insert rod 512 is pressed by the flange 422 to move upwards, and the limiting plate 513 also presses the spring 514 upwards to elastically deform the spring; after the flange 422 passes, the plate 421 continues to slide against the plunger 512, so that the spring 514 also continues to maintain the resiliently compressed state.

The space is a positioning hole, as shown in fig. 3, when the positioning hole slides to the position of the insert rod 512, the spring 514 elastically returns, and the positioning hole cooperates with the insert rod 512 to limit the displacement of the panel 20 in the X direction. Specifically, when the positioning hole slides to the position of the inserting rod 512 during the installation process, the inserting rod 512 slides down into the positioning hole under the action of the elastic restoring force and the gravity of the inserting rod until the limiting plate 513 abuts against the first slat 31. Preferably, when the limiting plate 513 abuts the first slat 31, the spring 514 is still in a resiliently compressed state, which is beneficial for improving the mounting reliability.

As shown in fig. 9, the end of the inserted link 512 located in the pin body 511 is provided with a first chamfer α, and an included angle β between the flange 422 and the plane of the plate body 421 is complementary to the first chamfer a. When the included angle between the flange 422 and the plane of the plate 421 is complementary to the first chamfer α, the flange 422 and the chamfer section are just fit, which is beneficial to better press the plunger 512 to move upward during the installation process. Preferably, the degree of the first chamfer α is 45 °.

Based on the above-mentioned mounting structure of the panel 20, the mounting method of the panel 20 of the present embodiment includes the following steps:

s1: the connecting plate 40 on the panel 20 is aligned with the mounting piece on the shell piece 10, mainly the position of the abdication part 42 and the first clamping plate 41 are sent into the corresponding opening;

s2: moving the panel 20 along the X direction to enable the folded edge 422 and the plate 421 to slide and press the inserting rod 512 in sequence, so that the spring 514 is elastically deformed;

s3: the movement is stopped until the positioning hole slides to the position of the inserting rod 512, and the installation is completed.

The method for disassembling the panel 20 of the present embodiment includes the following steps:

s1: pulling the pull handle 515 to disengage the plunger 512 from the positioning hole against the spring force;

s2: the panel 20 is slid and removed in the opposite direction to the installation, i.e. the removal is completed.

B. Second embodiment

In yet another embodiment, as shown in fig. 10, the elastic fastener 50 is a spring assembly 52, and the spring assembly 52 includes a spring fixing base 521 and a spring 522. The spring piece fixing base 521 is disposed on the first mounting member 30, and the spring piece 522 includes a mounting surface 5221, a pressing surface 5222, and a guide surface 5223, which are sequentially connected, and the spring piece 522 and the spring piece fixing base 521 are connected by the mounting surface 5221. Specifically, the spring plate fixing base 521 includes a set of horizontal bases 5211 parallel to the first slat 31 and a set of vertical bases 5212 perpendicular to the first slat. The horizontal base 5211 is provided with a connecting hole corresponding to the connecting hole of the first slat 31 for fixedly connecting the elastic fixing base 521 and the first slat 31. The vertical base 5212 is provided with a connecting hole corresponding to the connecting hole on the mounting surface 5221 for fixedly connecting the spring fixing base 521 and the spring 522. The first batten 31 is provided with a through avoidance channel 311 at a corresponding position for the elastic sheet 522 to pass through. Thereby, the spring plate assembly 52 and the first slat 31 are fixedly connected.

As shown in fig. 10, the pressing surface 5222 includes a first surface portion 5222a and a second surface portion 5222b, the first surface portion 5222a being adjacent to the mounting surface 5221 and the second surface portion 5222b being adjacent to the guide surface 5223. Specifically, the second face portion 5222b is substantially parallel to the mounting face 5221, i.e., the second face portion 5222b is substantially perpendicular to the first slat 31, and the top end of the second face portion 5222b is lower than the top end of the mounting face 5221 in vertical height. The first surface 5222a is used for connecting the second surface 5222b and the top end of the mounting surface 5221, so that the first surface 5222a is inclined from top to bottom, which is convenient for pressing during the mounting process to elastically deform the elastic sheet 522.

As shown in fig. 11, the relief portion 42 is an L-shaped hook, and the L-shaped hook includes a hook body 423 and a transition section 424 connecting the hook body 423 and the connecting portion body.

Referring to fig. 12 and 13, during the installation of the panel 20, the hook portion 4231 slides to press against the guide surface 5223 and the second surface 5222b to elastically deform the pressing surface 5222, and when the hook portion 4231 leaves the second surface 5222b, the elastic sheet 522 elastically returns to allow the space to abut against the second surface 5222b to limit the displacement of the panel 20 in the X direction. Specifically, the inclined surface 4231c first slidably contacts and presses the guide surface 5223 during the installation process, elastically deforming the pressing surface 5222; after the inclined surface 4231c passes through the guide surface 5223, the intermediate surface 4231b slides against the second surface 5222b, so that the pressing surface 5222 continues to be in an elastically compressed state; when the intermediate surface 4231b leaves the second surface 5222b, the yielding space completely reaches the second surface 5222b, and the second surface 5222b is no longer pressed and elastically restored, and at this time, the hook surface 4231a abuts against a side edge of the second surface 5222b, so as to limit the displacement of the panel 20 toward the transition section 424 in the X direction. In addition, the engagement of the catch 411 with the first opening 321 limits the displacement of the panel 20 away from the transition section 424 in the X-direction, so that the displacement of the panel 20 in the X-direction is fully limited.

As shown in fig. 7, the first clamping plate 41 is formed at a position close to the connecting plate body, the width of the clamping slot 411 is equal to the thickness of the second lath 32, and the matching of the clamping slot 411 and the first opening 321 limits the displacement of the panel 20 in the Y direction.

s2: the panel 20 is moved along the X direction, so that the hook 4231 slides to press the guide surface 5223 and the second surface 5222b in sequence, and the pressing surface 5222 is elastically deformed;

s3: the movement is stopped until the hook surface 4231a abuts against the side edge of the second surface 5222b, and the attachment is completed.

s1: pressing the first face 5222a to disengage the second face 5222b from the relief space;

In one embodiment, the connecting portion 40 further includes a second catch plate 43, and the housing member 10 is further provided with a second mounting member 30 'parallel to the first mounting member 30, the second mounting member 30' cooperating with the second catch plate 43 to limit displacement of the panel 20 in the Y-direction.
