Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a range hood. Background Art

[0002] There is a type of existing range hood including a body and a smoke damper. The body includes two side panels arranged at intervals. Hinges connecting the two side panels are respectively provided at both ends of the smoke damper. Both the side panels and the hinges are provided with through holes for threaded fasteners to penetrate, so that the side panels and the hinges are connected by threaded fasteners. Due to the existence of component processing errors, assembly positioning errors, and hole processing errors, the spacing between the through holes respectively opened in the two side panels and the spacing between the through holes respectively opened in the two hinges may be inconsistent, which will cause tension or pressure at both ends of the smoke damper, which may cause the smoke damper to deform and be damaged. When the smoke damper is made of glass and the two ends of the smoke damper are under pressure, the smoke damper will be arched and deformed, and there is a risk of bursting and damage during use. Utility Model Content

[0003] In view of this, the utility model provides a range hood capable of eliminating or reducing the tension or pressure on both ends of a smoke shield plate and preventing the smoke shield plate from being deformed and damaged.

[0004] The range hood provided by the utility model comprises a body and a smoke shield assembly, the body comprises a first side panel and a second side panel arranged along a first direction, the smoke shield assembly comprises a smoke shield, a first hinge connecting the first side panel and one end of the smoke shield, and a second hinge connecting the second side panel and the other end of the smoke shield; one of the first side panel and the first hinge is provided with a first connecting portion, and the other is provided with a first guide hole for the first connecting portion to move along the first direction; and / or one of the second side panel and the second hinge is provided with a second connecting portion, and the other is provided with a second guide hole for the second connecting portion to move along the first direction.

[0005] The range hood of the utility model allows for component processing errors in the body and the smoke shield assembly. The first guide hole allows the first connection part to approach or move away from the second connection part along the first direction, and the second guide hole allows the second connection part to approach or move away from the first connection part along the first direction, thereby allowing the distance from the first connection part to the second connection part in the first direction to vary within a certain range, so that deformation caused by compression or tension at both ends of the smoke shield can be released by the first guide hole and / or the second guide hole, thereby releasing the internal compressive stress or internal tensile stress of the smoke shield, thereby reducing the risk of deformation and damage to the smoke shield.

[0006] In one embodiment, the smoke shield is rotatably connected to the fuselage through a first hinge and a second hinge around a preset axis, and the first direction is parallel to the preset axis.

[0007] With this arrangement, the movement of the first connection part in the first guide hole along the first direction and the movement of the second connection part in the second guide hole along the first direction do not affect the rotation of the smoke shield relative to the fuselage, thereby not affecting the normal smoke shielding and collecting function of the smoke shield.

[0013] In this way, when the smoke shield assembly slides in the first guide hole through the first connecting column and the second connecting column slides in the second guide hole and completes the stress and strain release of the smoke shield, the first connecting column is connected to the first nut and the second connecting column is connected to the second nut, so that the relative position of the smoke shield and the fuselage can be fixed, thereby retaining only the freedom of the smoke shield to rotate relative to the fuselage around the preset axis.

[0014] In one embodiment, the width of the first guide hole and the width of the second guide hole are both constant in the first direction.

[0015] With such arrangement, the resistance encountered by the first connecting post when sliding in the first guide hole remains unchanged, and the resistance encountered by the second connecting post when sliding in the second guide hole remains unchanged, thereby ensuring smooth sliding.

[0017] With such arrangement, the assembly connection between the smoke shield assembly and the fuselage is easy and simple to implement.

[0018] In one embodiment, the first side panel further includes a first side wall bent and connected to the first flange, and the second side panel further includes a second side wall bent and connected to the second flange, and the first side wall and the second side wall are arranged along the first direction.

[0019] With such arrangement, the space between the first side wall and the second side wall can form an internal chamber of the range hood, which can be used to accommodate the fan.

[0020] In one embodiment, the smoke baffle includes a first end connected to a first hinge and a second end connected to a second hinge, an edge of the first end and the first side wall form a first step, an edge of the second end and the second side wall form a second step, the first step and the second step are symmetrical about a bisecting plane, the bisecting plane perpendicularly cuts the smoke baffle, and the distance from the first end to the bisecting plane is equal to the distance from the second end to the bisecting plane.

[0021] With this arrangement, the appearance of the range hood is neat and regular.

[0022] In one embodiment, the first hinge includes a third flange that fits the first flange, and the second hinge includes a fourth flange that fits the second flange;

[0023] One of the first flange and the third flange is provided with a first connecting portion, and the other is provided with a first guide hole; one of the second flange and the fourth flange is provided with a second connecting portion, and the other is provided with a second guide hole.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0032] In order to extract oil fumes more fully and efficiently, a type of range hood in the related art is equipped with a smoke baffle 21. The smoke baffle 21 is rotatably mounted on the body 10 of the range hood. A filter window is provided on one side of the body 10 for allowing the oil fume gas to be sucked into the fan. When the range hood is started and the oil fume extraction mode is running, the smoke baffle 21 rotates relative to the body 10 and opens the filter window. At the same time, a smoke blocking area connected to the filter window is formed between the smoke baffle 21 and the side where the filter window is located. After use, the smoke baffle 21 rotates relative to the body 10 to close the filter window.

[0033] See also Figure 1-2The utility model provides a range hood, including a body 10 and a smoke shield assembly 20, the body 10 includes a back panel 13, a first side panel 11 and a second side panel 12, the first side panel 11 and the second side panel 12 are arranged in sequence along a first direction, two ends of the back panel 13 are respectively connected to the first side panel 11 and the second side panel 12, the back panel 13 is used to be close to the kitchen wall, the back panel 13, the first side panel 11 and the second side panel 12 are surrounded to form a chamber for accommodating a fan, a filter window (not shown) is arranged between the first side panel 11 and the second side panel 12, and is arranged back to back with the back panel 13, the smoke shield assembly 20 includes a smoke shield plate 21, a first hinge 22 and a second hinge 23, the smoke shield plate 21 includes a first end and a second end arranged back to back, the first hinge 22 connects the first end with the first side panel 11, and the second hinge 23 connects the second end with the second side panel 12.

[0034] Furthermore, the range hood of the present invention also includes a smoke collecting drive component (not shown) for driving the smoke shield 21 to rotate relative to the body 10. The smoke collecting drive component can be installed on the body 10, and the smoke shield 21 can be rotated relative to the body 10 to open or close the filter window through the smoke collecting drive component, the first hinge 22 and the second hinge 23.

[0035] A conventional range hood is connected to the hinge and the body 10 by threaded fasteners. The first side panel 11 and the second side panel 12 are respectively provided with a first through hole and a second through hole for the threaded fasteners to pass through. The first hinge 22 and the second hinge 23 are respectively provided with a third through hole and a fourth through hole for the threaded fasteners to pass through. The first threaded fastener is passed through the first through hole and the third through hole to connect the first side panel 11 and the first hinge 22. The second threaded fastener is passed through the second through hole and the fourth through hole to connect the second side panel 12 and the second hinge 23.

[0036] Due to component processing errors of the first side panel 11 / the second side panel 12 and the first hinge 22 / the second hinge 23, there are assembly positioning errors between them, and hole position errors are generated when the first through hole / the second through hole / the third through hole / the fourth through hole are opened, there will be a situation where the center distance from the first through hole to the second through hole is inconsistent with the center distance from the third through hole to the fourth through hole, resulting in tension or pressure on both ends of the smoke barrier 21. When the center distance from the first through hole to the second through hole is smaller than the center distance from the third through hole to the fourth through hole, the two ends of the smoke barrier 21 are compressed and arched, which can easily cause damage to the smoke barrier 21, especially the glass smoke barrier 21 has the risk of bursting.

[0037] In view of this, the range hood of the utility model is improved as follows: one of the first side panel 11 and the first hinge 22 is provided with a first connecting portion, and the other is provided with a first guide hole 111 for the first connecting portion to move along the first direction; and / or one of the second side panel 12 and the second hinge 23 is provided with a second connecting portion, and the other is provided with a second guide hole 121 for the second connecting portion to move along the first direction. The first guide hole 111 has the function of guiding the first connecting portion to move along the first direction so that the smoke barrier assembly 20 as a whole moves relative to the body 10 along the first direction, and the second guide hole 121 has the function of guiding the second connecting portion to move along the first direction so that the smoke barrier assembly 20 as a whole moves relative to the body 10 along the first direction, and the smoke barrier assembly 20 as a whole moves relative to the body 10 along the first direction, so that the stress and strain generated by the tension or pressure on both ends of the smoke barrier 21 can be released.

[0038] In some embodiments, the first hinge 22 includes a first support 222 and a first rotating arm 223 hinged around a preset axis, the first support 222 is connected to the first side panel 11, the first rotating arm 223 is connected to one end of the smoke shield 21, one of the first support 222 and the first side panel 11 is provided with a first connecting portion, and the other is provided with a first guide hole 111, and the second hinge 23 includes a second support 232 and a second rotating arm 233 hinged around the preset axis, the second support 232 is connected to the second side panel 12, the second rotating arm 233 is connected to the other end of the smoke shield 21, one of the second support 232 and the second side panel 12 is provided with a second connecting portion, and the other is provided with a second guide hole 121. The smoke shield 21 is rotatably connected to the fuselage 10 around the preset axis through the first hinge 22 and the second hinge 23, wherein the first direction is parallel to the preset axis.

[0039] Specifically, see Figure 3-4 , see also Figure 2 The first guide hole 111 is a strip hole extending along the first direction, the second guide hole 121 is a strip hole extending along the first direction, the first connecting portion includes a first connecting column extending into the first guide hole 111, and the second connecting portion includes a second connecting column extending into the second guide hole 121. The first connecting column slides relative to the hole wall of the first guide hole 111 to shift in the first direction, and the second connecting column slides relative to the hole wall of the second guide hole 121 to shift in the first direction.

[0040] Figure 1 to Figure 4In the illustrated embodiment, the smoke barrier assembly 20 includes a first bolt and a second bolt, and the first connecting column and the second connecting column are both threaded columns. Specifically, the first connecting column is the screw portion of the first bolt, and the second connecting column is the screw portion of the second bolt. The first guide hole 111 is opened in the first side plate 11, and the second guide hole 121 is opened in the second side plate 12. The first hinge 22 also includes a first nut, and the second hinge 23 also includes a second nut. The first hinge 22 is provided with a first through-axis hole 221 for the first connecting column to pass through, and the second hinge 23 is provided with a second through-axis hole 231 for the second connecting column to pass through. The first connecting column penetrates from one side of the first through-axis hole 221, then penetrates the first through-axis hole 221 and the first guide hole 111 and is threadedly connected to the first nut, and the second connecting column penetrates from one side of the second through-axis hole 231, then penetrates the second through-axis hole 231 and the second guide hole 121 and is threadedly connected to the second nut.

[0041] by Figure 1 to Figure 4 Taking the range hood shown as an example, when installing the smoke shielding assembly 20 and the body 10, firstly, the screw portion of the first bolt is passed through the first through-axis hole 221 and the first guide hole 111, and the screw portion of the second bolt is passed through the second through-axis hole 231 and the second guide hole 121. The aperture of the first through-axis hole 221 matches the outer diameter of the screw portion of the first bolt, and the screw portion of the first bolt can move in the first direction in the first guide hole 111. The aperture of the second through-axis hole 231 matches the outer diameter of the screw portion of the second bolt, and the screw portion of the second bolt can move in the first direction in the second guide hole 121. Then, force is applied to the smoke shielding assembly 20 in the first direction so that the smoke shielding assembly 20 as a whole moves to a suitable position relative to the body 10 in the first direction. Finally, the first bolt is tightened with the first nut to fix the first hinge 22 and the first side panel 11, and the second bolt is tightened with the second nut to fix the second hinge 23 and the second side panel 12.

[0042] Optionally, the first direction is parallel to the back plate 13. In order to enable the smoke shielding assembly 20 as a whole to move accurately relative to the fuselage 10 along the first direction, to avoid the distance between the preset axis and the back plate 13 from changing, and to avoid the formation of an inclined angle between the preset axis and the back plate 13, the first guide hole 111 and the second guide hole 121 are both straight bar holes extending along the first direction, the width dimension of the first guide hole 111 and the width dimension of the second guide hole 121 are both constant values ​​in the first direction, the outer diameter of the first connecting column is equivalent to the width dimension of the first guide hole 111, and the outer diameter of the second connecting column is equivalent to the width dimension of the second guide hole 121. The width dimension of the first guide hole 111 and the width dimension of the second guide hole 121 are obtained by measuring the first guide hole 111 and the second guide hole 121 respectively in the direction perpendicular to the first direction.

[0043] Further, see Figure 2 , Figure 3 and Figure 4 The first side plate 11 includes a first flange 112 and a first side wall 113, the first flange 112 extends along the first direction into a flat plate structure, the first side wall 113 extends toward the ground and is bent and connected to the first flange 112, the first guide hole 111 is opened in the first flange 112, the second side plate 12 includes a second flange 122 and a second side wall 123, the second flange 122 extends along the first direction into a flat plate structure, the second side wall 123 extends toward the ground and is bent and connected to the second flange 122, the second guide hole 121 is opened in the second flange 122, the first side wall 113 and the second side wall 123 are arranged at intervals along the first direction, and the filter window is arranged between the first side wall 113 and the second side wall 123.

[0044] Furthermore, the first support 222 includes a third flange 2221 that is fitted with the first flange 112, the second support 232 includes a fourth flange 2321 that is fitted with the second flange 122, the first through-axis hole 221 is provided in the third flange 2221, and the second through-axis hole 231 is provided in the fourth flange 2321. In the process that the first connecting portion moves along the first guide hole 111 and the second connecting portion moves along the second guide hole 121 so that the smoke barrier assembly 20 as a whole moves relative to the fuselage 10 along the first direction, the first flange 112 and the third flange 2221 always maintain a relatively sliding plane fitting state, and the second flange 122 and the fourth flange 2321 always maintain a relatively sliding plane fitting state, thereby ensuring that the smoke barrier assembly 20 as a whole moves accurately along the first direction, and preventing the smoke barrier assembly 20 from changing its posture and causing the extension direction of the preset axis to change.

[0045] As mentioned above, the smoke baffle 21 includes a first end and a second end which are arranged opposite to each other and connected to the first hinge 22 and the second hinge 23 respectively. The edge of the first end forms a first step with the first side wall 113, and the edge of the second end forms a second step with the second side wall 123. The first step and the second step are symmetrical about the bisecting plane, wherein the bisecting plane refers to a plane vertically cutting the smoke baffle 21, and the distance from the edge of the first end to the bisecting plane is equal to the distance from the edge of the second end to the bisecting plane. The first step can be either the edge of the first end protruding from the first side wall 113 or the first side wall 113 protruding from the edge of the first end, and the second step can be either the edge of the second end protruding from the second side wall 123 or the second side wall 123 protruding from the edge of the second end.

[0046] It can be understood that in other embodiments, the side of the first side wall 113 facing away from the second side wall 123 is flush with the edge of the first end, and the side of the second side wall 123 facing away from the first side wall 113 is flush with the edge of the second end.

[0047] by Figure 1 to Figure 4Taking the range hood shown as an example, force is applied to the smoke shield assembly 20 to enable the smoke shield assembly 20 to move as a whole relative to the body 10 along a first direction. When the smoke shield assembly 20 moves to a suitable position, the first step and the second step are symmetrical about the bisecting plane, or the first side wall 113 is flush with the first end / the second side wall 123 is flush with the second end, and then the first connecting column is fastened with the first nut and the second connecting column is fastened with the second nut.

[0048] It can be understood that in some embodiments not shown in the figures, the first guide hole 111 can also be opened in the first hinge 22, the first through-axis hole 221 is correspondingly opened in the first side panel 11, the second guide hole 121 can also be opened in the second hinge 23, and the second through-axis hole 231 is correspondingly opened in the second side panel 12; the first hinge 22 and the first side panel 11, and the second hinge 23 and the second side panel 12 can also be fixedly connected by other types of fasteners, such as rivets or clips, and are not limited to being fixedly connected by threaded fasteners; the first guide hole 111 and the second guide hole 121 can be either through holes or blind holes, as long as the first connecting portion and the second connecting portion are allowed to move in the first guide hole 111 and the second guide hole 121 respectively along the first direction.

[0049] The range hood of the utility model allows for component processing errors in the body and the smoke shield assembly. The first guide hole allows the first connection part to approach or move away from the second connection part along the first direction, and the second guide hole allows the second connection part to approach or move away from the first connection part along the first direction, thereby allowing the distance from the first connection part to the second connection part in the first direction to vary within a certain range, so that deformation caused by compression or tension at both ends of the smoke shield can be released by the first guide hole and / or the second guide hole, thereby releasing the internal compressive stress or internal tensile stress of the smoke shield, thereby reducing the risk of deformation and damage to the smoke shield.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
