Description

Technical Field

[0001] The present invention belongs to the technical field of range hoods, and particularly relates to a range hood. Background Art

[0002] In order to make up for the insufficient light in the usage area caused by the range hood itself blocking or poor environmental light sources and improve the user experience, a lighting structure is added to the range hood. For the lighting structure of existing European-style T-shaped range hoods, an integrated LED lamp assembly with a fixed structure is installed on the reserved hole position of the smoke collecting hood of the range hood.

[0003] The existing installation structure of the LED lamp assembly itself requires designing reserved installation hole positions on the sheet metal structural parts, which will increase the complexity of the structural design, reduce its manufacturability, and increase the quality control risk points; moreover, since the LED lamp assembly is installed in the smoke collecting cavity, as the service life increases, it is inevitable that oil fumes will enter the inside of the smoke collecting hood from the installation gap, polluting and corroding the electrical components in the smoke collecting hood. And when a fire occurs, although the LED lamp cover uses heat-resistant and flame-retardant materials, because it is made of plastic itself, it cannot completely prevent the spread of the fire, but will instead become a combustion point; opening reserved hole positions on the smoke collecting hood destroys the overall appearance integrity of the smoke collecting hood and may become an appearance pain point for users; the LED lamp assembly is mainly composed of lamp beads, lamp sockets, lamp covers (heat-resistant and flame-retardant), fixed structures (elastic pieces, etc.), with a complex structure and relatively high cost; the illumination brightness uniformity of the LED lamp assembly is poor, and the brightness generally cannot be adjusted. Summary of the Invention

[0004] In order to solve the problem that oil fumes will enter the smoke collecting hood and pollute and corrode electrical components during long-term use of the current range hood, the present invention provides a range hood.

[0005] The present invention is implemented as follows:

[0006] The present invention provides a range hood, including a range hood body and a lighting assembly. A switch glass panel is installed on the front end face of the range hood body;

[0007] The front end face of the range hood body is an inclined surface that slopes downward towards the back of the range hood body. The lighting assembly is arranged between the switch glass panel and the front end face of the range hood body, and the lighting assembly is installed in the switch glass panel, so that the light irradiates towards the bottom direction of the switch glass panel.

[0008] A further improvement to the range hood of the present invention is that a mounting groove is provided on the back of the switch glass panel, the lighting assembly is installed in the mounting groove, the light emitted by the lighting assembly is directed toward the bottom of the mounting groove, refracted into the switch glass panel, and then refracted from the bottom of the switch glass panel to the stove.

[0009] A further improvement to the range hood of the present invention is that the lighting assembly includes a lamp housing and a lighting lamp arranged in the lamp housing; the lamp housing is installed in the installation groove to form a chamber, and the lighting lamp is arranged above the chamber so that the light is irradiated toward the bottom of the switch glass panel.

[0010] A further improvement to the range hood of the present invention is that the lamp housing includes a mounting plate and a baffle; one end of the mounting plate is inserted into the mounting groove, and the other end is connected to the baffle, and one end of the baffle away from the mounting plate is abutted against the switch glass panel to enclose the mounting groove to form a chamber; the lighting lamp is installed on the mounting plate so that the light shines toward the bottom of the mounting groove.

[0011] A further improvement to the range hood of the present invention is that the baffle is an arc-shaped plate convex toward the front end surface away from the switch glass panel.

[0012] A further improvement to the range hood of the present invention is that it further comprises a connecting piece, and the lighting assembly is detachably connected to the switch glass panel via the connecting piece.

[0013] A further improvement to the range hood of the present invention is that the connecting member comprises a fixing seat and a fixing buckle; a limit slot is provided on the fixing seat; and upper and lower limit slots of the fixing buckle are arranged in the limit slot.

[0014] A further improvement to the range hood of the present invention is that the angle γ between the inclined surface and the horizontal lower end surface of the smoke collecting hood of the range hood body is 100° to 120°.

[0015] A further improvement to the range hood of the present invention is that the angle α and angle γ formed by the back surface of the switch glass panel and the upper end surface of the smoke hood of the range hood body are complementary angles, and the angle α satisfies: 60°≤α≤β≤80°, wherein the angle β is the angle formed by the front end surface of the switch glass panel and the upper end surface of the smoke hood of the range hood body.

[0016] A further improvement to the range hood of the present invention is that the front end surface of the switch glass panel is opaque.

[0017] Compared with the prior art, the beneficial effects of the present invention adopting the above solution are as follows:

[0018] Since the lighting component of this embodiment is not installed at the bottom of the smoke collecting hood, this avoids opening installation holes at the bottom of the smoke collecting hood, ensuring the integrity and aesthetics of the smoke collecting hood, facilitating scrubbing, and also preventing oil fumes from entering the interior of the smoke collecting hood and corroding electrical components. Since the lighting component is disposed between the switch glass panel and the front end face of the range hood body, that is, the lighting component is outside the smoke collecting hood, this avoids the influence of oil fumes and high temperatures, effectively solving the problems of easy contamination and deformation existing in the lighting components of current range hoods. Also, since the front end face of the range hood body is an inclined surface that slopes downward toward the back of the range hood body, the lighting component is installed in the switch glass panel, and the light is irradiated toward the bottom direction of the switch glass panel, which enables the light emitted by the lighting component to be refracted into the switch glass panel and then refracted out from the bottom of the switch glass panel and irradiated toward the cooking stove to achieve cooking lighting.

[0036] In order to more clearly understand the above - mentioned objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0037] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0038] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The meaning of "a plurality" is two or more unless otherwise specifically defined.

[0039] In the present invention, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The current range hood includes a hood body 1 and a lighting assembly 2. A switch glass panel 12 is installed on the front end face of the hood body 1. For aesthetics, usually the switch glass panel 12 is in a cuboid structure and closely adheres to the front end face of the hood body 1. In addition, the switch glass panel 12 is provided with a power-on / off touch button, a timing touch button, a wind volume control touch button, etc. Users can use these touch buttons to turn on, turn off, time, and adjust the gear of the hood body 1.

[0041] Although the current range hood also has a lighting assembly 2, the lighting assembly 2 is usually installed at the bottom of the smoke collecting hood 11 of the hood body 1. At this time, it is inevitable to open installation holes in the smoke collecting hood 11, thus damaging the integrity of the smoke collecting hood 11. After long-term use, oil fumes will enter the smoke collecting hood through the installation gap and corrode the electrical components, and it is not conducive to cleaning the smoke collecting hood 11. In addition, the lighting assembly 2 will be contaminated and its transparency will be reduced after long-term contact with oil fumes, and it will be deformed after long-term contact with high temperature.

[0042] As Figures 1 - 3 shown, in order to solve the above problems, the front end face of the hood body 1 of the range hood in this embodiment is an inclined surface that slopes downward toward the back of the hood body 1. The lighting assembly 2 is arranged between the switch glass panel 12 and the front end face of the hood body 1, and the lighting assembly 2 is installed in the switch glass panel 12 so that the light irradiates toward the bottom direction of the switch glass panel 12.

[0043] In this embodiment, since the lighting assembly 2 of this embodiment is not installed at the bottom of the smoke collecting hood 11, this avoids opening installation holes at the bottom of the smoke collecting hood 11, ensuring the integrity and aesthetics of the smoke collecting hood 11, facilitating scrubbing, and also preventing oil fumes from entering the interior of the smoke collecting hood 11 and corroding electrical components. Since the lighting assembly 2 of this embodiment is disposed between the switch glass panel 12 and the front end face of the range hood body 1, that is, the lighting assembly 2 is outside the smoke collecting hood 11, this avoids the influence of oil fumes and high temperatures, and effectively solves the problems of easy contamination and deformation existing in the lighting assemblies of current range hoods. Also, since the front end face of the range hood body 1 of this embodiment is an inclined surface that slopes downward toward the back of the range hood body 1, the lighting assembly 2 is installed in the switch glass panel 12, and the light is irradiated toward the bottom direction of the switch glass panel 12, so that the light emitted by the lighting assembly 2 can be refracted into the switch glass panel 12, and then refracted out from the bottom of the switch glass panel 12 and irradiated toward the cooking appliance to achieve cooking lighting.

[0044] Preferably, the front end face of the switch glass panel 12 is light-tight. For example, a light-shielding film is attached to the front end face of the switch glass panel 12, which avoids the light from being emitted from the front end face of the switch glass panel 12 and ensures the light intensity irradiated onto the cooking appliance.

[0045] Since the lighting assembly 2 is disposed between the switch glass panel 12 and the front end face of the range hood body 1, the clamping force between the switch glass panel 12 and the front end face of the range hood body 1 plays a first stabilizing role on the lighting assembly 2. And the lighting assembly 2 is installed in the switch glass panel 12, then the acting force of the switch glass panel 12 on the lighting assembly 12 plays a second stabilizing role on the lighting assembly 2, so that it can effectively prevent the lighting assembly 2 from falling off during transportation.

[0046] As Figure 3 and Figure 4 shown, further, the installation height of the range hood by users is generally limited to a position 650 mm to 700 mm above the cooking stove. Therefore, in order to make the light refracted from the bottom of the switch glass panel 12 irradiate the cooking appliance as much as possible, in a specific implementation, the included angle γ between the bottom of the inclined surface and the horizontal lower end face of the smoke collecting hood 11 of the range hood body 1 is 100° to 120°, preferably 105° to 115°.

[0047] Generally, the switch glass panel 12 has a cuboid structure. When the switch glass panel 12 is installed on the front end face of the range hood body 1, the front end face of the switch glass panel 12 is parallel to the back face of the switch glass panel, that is, the included angle α formed by the back face of the switch glass panel 12 and the upper end face of the smoke collecting hood 11 of the range hood body 1 satisfies: α = β, where the included angle β is the included angle formed by the front end face of the switch glass panel 12 and the upper end face of the smoke collecting hood of the range hood body 1. Additionally, since the back face of the switch glass panel 12 is closely attached to the front end face of the range hood body 1, the included angle α formed by the back face of the switch glass panel 12 and the upper end face of the smoke collecting hood 11 of the range hood body 1 and the included angle γ are supplementary angles to each other.

[0048] Because an installation groove 121 needs to be opened on the back face of the switch glass panel 12, and in order to reduce the propagation distance of the light, the installation groove 121 is usually opened near the bottom of the switch glass panel 12. Therefore, for the convenience of opening the installation groove 121, the included angle α formed by the back face of the switch glass panel 12 of this embodiment and the upper end face of the smoke collecting hood of the range hood body 1 satisfies: α < β, where the included angle β is the included angle formed by the front end face of the switch glass panel 12 and the upper end face of the smoke collecting hood of the range hood body 1. At this time, the front end face of the switch glass panel 12 and the back face of the switch glass panel 12 are not parallel to each other, resulting in the thickness of the lower part of the switch glass panel 12 being greater than the thickness of the upper part of the switch glass panel 12, which is convenient for opening the installation groove 121 in the lower part of the switch glass panel 12. In this embodiment, 60° ≤ α ≤ β ≤ 80°, preferably, 65° ≤ α ≤ β ≤ 75°.

[0049] Preferably, the bottom face of the switch glass panel 12 is perpendicular to the back face of the switch glass panel 12.

[0050] As Figures 5 - 8 shown, further, an installation groove 121 is opened on the back face of the switch glass panel 12, and the lighting component 2 is installed in the installation groove 121. The light emitted by the lighting component 2 shoots towards the bottom of the installation groove 121, is refracted into the switch glass panel 12, and then is refracted out from the bottom of the switch glass panel 12 and shoots towards the cooking appliance.

[0051] After the light emitted by the lighting component 2 shoots towards the bottom of the installation groove 121, because the front end face of the switch glass panel 12 is opaque, the light is refracted into the switch glass panel and then propagates downward, and finally is refracted out from the bottom of the switch glass panel 12. Because the lower end of the switch glass panel 12 is inclined towards the back of the range hood body 1, the refracted light finally shoots towards the cooking appliance.

[0052] Preferably, the light emitted by the lighting component 2 is perpendicularly incident on the bottom of the installation groove 121. Since the refractive index of glass is generally between 1.5 and 1.9, if the light is perpendicular to the bottom of the installation groove 121, it can ensure that the light entering the switch glass panel 12 can be refracted out from the bottom of the switch glass panel 12 as soon as possible and then emitted towards the cooking appliance.

[0053] As Figure 5 and Figure 6 shown, further, the lighting component 2 includes a lamp housing 21 and a lighting lamp disposed inside the lamp housing 21; the lamp housing 21 is installed in the installation groove 121 to form a chamber, and the lighting lamp is disposed above the chamber so that the light irradiates towards the bottom direction of the switch glass panel 12. The light first enters the switch glass panel 12 by refraction from the bottom of the installation groove 121, propagates towards the bottom direction of the switch glass panel 12 inside the switch glass panel 12, and then is refracted out from the bottom surface of the switch glass panel 12 and finally emitted towards the cooking appliance.

[0054] As Figure 9 and Figure 10 shown, the lamp housing 21 includes a mounting plate 211 and a baffle plate 212; one end of the mounting plate 211 is inserted into the installation groove 121, and the other end is connected to the baffle plate 212. One end of the baffle plate 212 away from the mounting plate 211 abuts against the switch glass panel 12 to enclose the installation groove 121 to form a chamber; the lighting lamp is installed on the mounting plate 211 so that the light irradiates towards the bottom direction of the installation groove 12, and preferably the light is perpendicularly incident on the bottom of the installation groove 12.

[0055] As Figure 10 shown, in a specific embodiment, the lamp housing 21 has a "7"-shaped structure, wherein the mounting plate 211 and the baffle plate 212 are integrally formed. When the mounting plate 211 is inserted into the installation groove 121, the bottom of the baffle plate 212 abuts against the back surface of the switch glass panel 12, thus enclosing the installation groove 121 to form a chamber.

[0056] As Figure 9 and Figure 10 shown, preferably, the baffle plate 22 is an arc-shaped plate protruding towards the front surface direction away from the switch glass panel 12, which increases the space of the chamber.

[0057] As Figure 5 and Figure 6 shown, further, the range hood further includes a connecting member 3, and the lighting component 2 is detachably connected to the switch glass panel 12 through the connecting member 3. The connecting member 3 plays a triple stabilizing role for the lighting component 2.

[0058] As Figure 6 , as Figures 11 - 15As shown, the connecting member 3 includes a fixing base 31 and a fixing buckle 32; a limiting bayonet 33 is formed on the fixing base 31; the fixing buckle 32 is vertically and limitably clamped in the limiting bayonet 33.

[0059] In a specific implementation, the fixing base 31 is installed on the back of the switch glass panel 12, as Figure 6 shown, the fixing buckle 32 is connected to the lamp housing 21, as Figure 13 and Figure 14 shown. Preferably, the fixing buckle 32 and the lamp housing 21 are fixedly connected by screws. During installation, the lighting assembly 2 and the fixing buckle 32 are integrally fixed in an up-and-down limiting manner through the fixing buckle 32 and the limiting bayonet 33, which is convenient for quick disassembly and assembly.

[0060] As Figure 16 shown, the illuminating lamp includes multiple groups of lamp beads, and the controller of the range hood body is electrically connected to each group of lamp beads for adjusting the intensity of the illuminating lamp.

[0061] In a specific embodiment, the illuminating lamp is a light strip. Along the length direction of the lamp housing 21, the light strip is sequentially divided into three areas A, B, and C, and at least one LED lamp bead is provided in each area. Due to the multi-directionality of the light propagation inside the glass, the position and number of the lamp beads only affect the intensity of the light finally emitted to the cooker, and have little influence on its uniformity. Therefore, the brightness adjustment of the illuminating lamp can be divided into three gears. When the first gear is turned on, only the LED lamp beads in the middle area B emit light; when the second gear is turned on, the LED lamp beads in the two side areas A and C emit light; when the third gear is turned on, the LED lamp beads in areas A, B, and C all emit light. Preferably, the area division of the light strip can be further refined, and the corresponding gears can also be refined.

[0062] Installation process:

[0063] The maintenance personnel first fixedly connect the lamp housing 21 and the fixing buckle 32 by screws and install the illuminating lamp (light strip) on the mounting plate 211; then, install the lamp housing 21, the illuminating lamp and the fixing buckle 32 as a whole, that is, insert the mounting plate 211 into the mounting groove 121, and at the same time, the fixing buckle 32 is snapped into the limiting bayonet 33 from top to bottom. When the snapping is in place, the bottom of the baffle 212 abuts against the back of the switch glass panel 12 and covers the mounting groove 121 to form a chamber. At this time, the illuminating lamp is located above the chamber. When the illuminating lamp emits light, the light is vertically emitted to the bottom of the mounting groove 121, then refracted into the switch glass panel 12, and then refracted out from the bottom surface of the switch glass panel 12 and finally emitted to the cooker.
