Description

Technical Field

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

[0002] The existing range hood, such as the structure disclosed in the Chinese utility model patent "Random Hood" with patent number 202222310726.8 and authorization announcement number CN218295897U, includes: a body; a lighting lamp, which is driven by a driving mechanism and is rotatably connected to the body in an angle-adjustable manner; a position sensor, which is fixed relative to the body and is used to detect the height of the pot on the stove below the body; a controller, which is electrically connected to the position sensor and the driving mechanism, and controls the driving mechanism to move according to the pot height signal obtained by the position sensor, and then adjusts the lighting lamp to an irradiation angle that matches the pot height. After the range hood obtains the pot height information through the position sensor, it can control the driving mechanism to move according to the pot height signal obtained by the position sensor, and then adjust the lighting lamp to an irradiation angle that matches the pot height, thereby ensuring that users can experience better lighting effects when using pots of different heights, meeting the different needs of users.

[0003] When cooking, if the user temporarily leaves the stove for some reason, he cannot check the cooking status of the food in the pot from a distance. He must walk closer to the stove to check from above the pot. Moreover, the range hood is located above the pot, which to a certain extent affects the user's view from above the pot, causing inconvenience to the user. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a range hood in view of the current status of the prior art to improve the user experience.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a range hood, comprising:

[0006] The box body is hollow inside, the side of the box body facing the user is the front side, and the upper side of the front side wall of the box body is provided with a smoke inlet for the oil smoke flow to enter the box body;

[0007] It is characterized by also including:

[0008] A dimming mirror glass that can be adjusted to a transparent or opaque state is arranged on the front side of the box body and below the smoke inlet, with the front of the dimming mirror glass facing forward and tilting forward from bottom to top;

[0009] A component acting on the dimming mirror glass to switch the dimming mirror glass between a transparent state and an opaque state;

[0010] At the same time, a reflective layer is provided on the back side of the dimming mirror glass, and the reflective layer is arranged to reflect the light incident from the front side of the dimming mirror glass.

[0011] In this way, when the user needs to check the cooking status of the food in the pot, the dimming mirror glass can be adjusted to a transparent state. At this time, the light passes through the dimming mirror glass into the reflective layer and is reflected by the reflective layer, so that the user can observe the cooking status of the food in the pot through the dimming mirror glass. At this time, the user can observe from a distance without viewing from above the pot, thereby improving the user experience; conversely, when the user does not need to check the cooking status of the food in the pot, the dimming mirror glass can be adjusted to an opaque state. At this time, the dimming mirror glass blocks the light from entering the reflective layer and cannot reflect the light.

[0012] Preferably, the dimming mirror glass is an electrically controlled dimming mirror glass which is transparent when powered on and opaque when powered off;

[0013] The components include a power circuit for supplying power to the dimming mirror glass and a switch for controlling the on and off of the power circuit.

[0014] In this way, the transparency of the dimming mirror glass can be adjusted by controlling the switch, which is convenient to use.

[0015] Preferably, the box further comprises a sensing module for sensing a human body and a controller electrically connected to an output end of the sensing module, wherein the output end of the controller is electrically connected to the switch element.

[0016] When the range hood is in operation and the sensing module senses that a human body is away from the range hood, the controller controls the switch to connect the power circuit for supplying power to the dimming mirror glass, thereby automatically switching the dimming mirror glass to a transparent state, making it convenient for the user to view the cooking conditions in the pot from a distance.

[0017] Preferably, it also includes a voice module disposed on the box body and a controller for receiving the output signal of the voice module, and the output end of the controller is electrically connected to the switch element, so that the user can control the transparent state of the dimming mirror glass by voice, which is convenient to use.

[0018] In the above scheme, in order to adjust the transparency, preferably, the dimming mirror glass comprises a liquid crystal layer located in the center, a conductive film wrapped on the front and rear sides of the liquid crystal layer, a heat-insulating film layer wrapped on the front and rear sides of the conductive film, and a glass layer wrapped on the front and rear sides of the heat-insulating film layer, and the back of the rear glass layer is provided with the above-mentioned reflective layer;

[0019] When the power is on, the liquid crystal molecules in the liquid crystal layer are in a neatly arranged state, and when the power is off, the liquid crystal molecules in the liquid crystal layer are in an irregularly dispersed state.

[0020] Furthermore, the reflective layer is a thin silver layer, and the heat-insulating film layer is an EVA film layer. In addition, the reflective layer can also be a thin gold layer, an aluminum layer, etc.

[0021] In the above solutions, for the convenience of user observation, preferably, the angle between the dimming mirror glass and the vertical plane is 45°±10°. According to the principle of mirror incident angle = reflection angle, the light incident on the pot under the dimming mirror glass is just reflected horizontally, and the user can just see it.

[0022] Furthermore, the front side wall of the box body is inclined forward from bottom to top, and the dimming mirror glass is attached to the lower side of the front side wall of the box body.

[0023] In order to meet the needs of different users, the dimming mirror glass can be movably arranged on the front side of the box body to adjust the angle between the dimming mirror glass and the vertical plane, so that the user can adjust the angle of the dimming mirror glass according to his or her height.

[0024] To facilitate adjustment of the angle of the dimming mirror glass, preferably, it also includes an axially retractable push rod, the first end of which is arranged in the box body so as to be rotatable up and down around a rotating shaft extending left and right, and the second end of which passes through a through hole on the front side wall of the box body and is connected to the dimming mirror glass.

[0025] Compared with the prior art, the advantage of the utility model lies in that: by providing dimming mirror glass, a reflective layer and a component acting on the dimming mirror glass to switch the dimming mirror glass between a transparent state and an opaque state, when the user needs to check the cooking status of the food in the pot, the dimming mirror glass can be adjusted to a transparent state. At this time, light enters the reflective layer through the dimming mirror glass and is reflected by the reflective layer, so that the user can observe the cooking status of the food in the pot through the dimming mirror glass. At this time, the user can observe from a distance without viewing from above the pot, thereby improving the user experience; conversely, when the user does not need to check the cooking status of the food in the pot, the dimming mirror glass can be adjusted to an opaque state. At this time, the dimming mirror glass blocks the light from entering the reflective layer and thus cannot reflect the light. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 4 As shown, a preferred embodiment of a range hood of the utility model is shown, and the range hood includes a box body 1, a dimming mirror glass 2, components, a reflective layer 3, and a fan system.

[0032] The box body 1 is hollow inside, and the side of the box body 1 facing the user is the front side. The front side wall 10 of the box body 1 is inclined forward from bottom to top, and a smoke inlet 11 is provided on the upper side of the front side wall 10, and a smoke outlet is provided on the top wall of the box body 1.

[0033] The fan system is arranged in the box 1, and is used to drive the oil smoke flow to be sucked into the box 1 through the smoke inlet 11 and discharged through the smoke outlet. In this embodiment, the fan system is a prior art and is not shown in the figure.

[0034] The dimming mirror glass 2 can be adjusted to a transparent or opaque state and is arranged at the front side of the box body 1 and below the smoke inlet 11. The front of the dimming mirror glass 2 faces forward and is tilted forward from bottom to top. In this embodiment, the angle between the dimming mirror glass 2 and the vertical plane is 45°±10°, and the dimming mirror glass 2 can be movably arranged at the front side of the box body 1 to adjust the angle between the dimming mirror glass 2 and the vertical plane. Figure 4 As shown, in order to adjust the angle of the dimming mirror glass 2, the range hood of this embodiment further includes an axially retractable push rod 4, the first end of which faces backward and is arranged in the box body 1 so as to be rotatable up and down around a rotating shaft 41 extending left and right, and the second end of which faces forward and passes through a through hole on the front side wall 10 of the box body 1 and then connects to the dimming mirror glass 2. Thus, the dimming mirror glass 2 can move relative to the box body 1, and the dimming mirror glass 2 can move to a position that fits the lower side of the front side wall of the box body 1.

[0035] In order to adjust the transparency, the dimming mirror glass 2 of this embodiment is an electrically controlled dimming mirror glass that is transparent when powered on and opaque when powered off, and has a liquid crystal layer 21 located in the center, a conductive film 22 wrapped on the front and rear sides of the liquid crystal layer 21, a heat-insulating film 23 layer wrapped on the front and rear sides of the conductive film 22 (the heat-insulating film 23 layer is an EVA film layer), and a glass layer 24 wrapped on the front and rear sides of the heat-insulating film 23 layer. When powered on, the liquid crystal molecules in the liquid crystal layer 21 are neatly arranged, making the dimming mirror glass 2 transparent. When powered off, the liquid crystal molecules in the liquid crystal layer 21 are irregularly scattered, making the dimming mirror glass 2 opaque. For details, please refer to Figure 3 , 4 .

[0036] The above components act on the dimming mirror glass 2 to switch the dimming mirror glass 2 between transparent and opaque states. In this embodiment, the component includes a power circuit for powering the dimming mirror glass 2 and a switch for controlling the on and off of the power circuit. In order to improve the user experience, this embodiment also includes a sensing module for sensing the human body provided on the box 1, a voice module provided on the box 1, and a controller electrically connected to the output end of the sensing module and capable of receiving the output signal of the voice module, and the output end of the controller is electrically connected to the switch. During use, when the user is relatively far away from the range hood, the switch can be controlled by voice to adjust the transparency of the dimming mirror glass 2.

[0037] At the same time, a reflective layer 3 (a thin silver layer) is provided on the back side of the dimming mirror glass 2 (i.e., the back side of the glass layer behind the dimming mirror glass 2), and the reflective layer 3 is arranged to reflect the light incident from the front side of the dimming mirror glass 2.

[0038] In this way, when the user needs to check the cooking status of the food in the pot, the dimming mirror glass 2 can be adjusted to a transparent state. At this time, the light is emitted into the reflective layer 3 through the dimming mirror glass 2 and is reflected by the reflective layer 3, so that the user can observe the cooking status of the food in the pot through the dimming mirror glass 2. At this time, the user can observe from a distance without viewing from above the pot, thereby improving the user experience; conversely, when the user does not need to check the cooking status of the food in the pot, the dimming mirror glass 2 can be adjusted to an opaque state. At this time, the dimming mirror glass 2 blocks the light from entering the reflective layer and thus cannot reflect the light.

[0039] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "upper", "lower", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
