Description

Technical Field

[0001] The utility model relates to an automatic opening and closing structure of a ceiling-mounted range hood.

Background Art

[0002] A range hood is a common kitchen appliance. When the range hood works, it can suck the oil fumes generated by cooking food to prevent the oil fumes from escaping everywhere and affecting the ambient air. In some usage scenarios of island counter designs, traditional wall-mounted range hoods can no longer meet the usage requirements. Therefore, a ceiling-mounted range hood has emerged on the market. It is fixed on the ceiling and is set corresponding to the position of the gas stove on the island counter. However, the air inlet of this ceiling-mounted range hood is always exposed, especially the oil fume air net, which is extremely easy to be contaminated with dust, resulting in the blockage of the air holes and affecting the suction.

[0003] Therefore, it is necessary to make further improvements to it.

Content of the Utility Model

[0004] The purpose of the utility model is to overcome the above problems. We provide an automatic opening and closing structure of a ceiling-mounted range hood, which solves the problem of dust accumulation on the oil fume air net of the range hood.

[0005] To achieve the above purpose, the utility model provides an automatic opening and closing structure of a ceiling-mounted range hood, which includes a machine body, a first panel and a second panel. A ventilation device is arranged inside the machine body, and an air inlet is arranged at the bottom of the machine body. The first panel and the second panel are arranged at the bottom of the machine body and are used to block the air inlet. Opposite-opening guide rails are arranged on both sides of the bottom of the machine body. The first panel is connected to the first sliding seat of the opposite-opening guide rail, and the second panel is connected to the second sliding seat of the opposite-opening guide rail. A driving mechanism for driving the first panel or the second panel to move is arranged on the machine body. The first panel and the second panel can slide relative to each other to block or expose the air inlet.

[0006] In one or more embodiments, the driving mechanism is a cylinder. The cylinder is installed and fixed on the machine body, and the cylinder shaft of the cylinder is connected to the first panel or the second panel.

[0007] In one or more embodiments, lighting lamps and control boards are arranged on both the first panel and the second panel. The control board is electrically connected to the lighting lamps, the ventilation device and the driving mechanism.

[0008] In one or more embodiments, one or more oil fume air nets are detachably installed on the air inlet.

[0009] In one or more embodiments, a mounting bracket is arranged on the machine body, and mounting holes are reserved on the mounting bracket.

[0010] In one or more embodiments, the exhaust device includes a volute, a turbine, and a motor. The turbine is disposed inside the volute, and the motor is connected to the turbine to drive it to rotate. An air inlet grille communicating with the interior of the body is provided on the volute.

[0011] The effect of the present utility model compared with the background technology is that the ceiling-mounted range hood has a first panel and a second panel that can automatically open and close. When the range hood is idle, the first panel and the second panel can block the air inlet to prevent dust accumulation. The first panel and the second panel are connected by an opposed guide rail. When the first panel moves, the second panel can also move accordingly, so as to simultaneously move to block or expose the air inlet.

Detailed Embodiments

[0016] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0017] Referring to the attached Figures 1-4 , the present application provides an automatically opening and closing structure for a ceiling-mounted range hood, which includes a body 1, a first panel 2, and a second panel 3. An exhaust device 4 is provided inside the body. An air inlet is provided at the bottom of the body. The first panel 2 and the second panel 3 are disposed at the bottom of the body and are used to block the air inlet. Opposed guide rails 5 are provided on both sides of the bottom of the body. The first panel 2 is connected to the first sliding seat 6 of the opposed guide rail, and the second panel 3 is connected to the second sliding seat 7 of the opposed guide rail. A driving mechanism 8 for driving the first panel or the second panel to move is provided on the body. The first panel and the second panel can slide relative to each other to block or expose the air inlet. In this embodiment, the driving mechanism is connected to the first panel. When the driving mechanism drives the first panel to slide outwards, the second panel will also slide outwards in the opposite direction, thereby exposing the air inlet for sucking oil fumes; when the driving mechanism drives the first panel to slide inwards, the second panel will also slide inwards until it contacts the first panel to block the air inlet.

[0018] The driving mechanism 8 is a cylinder, which is fixedly installed on the body 1. The cylinder shaft of the cylinder is connected to the first panel or the second panel. Direct driving by the cylinder has the advantages of simple structure and easy installation.

[0019] Both the first panel 2 and the second panel 3 are provided with a lighting lamp 9 and a control board 10. The control board is electrically connected to the lighting lamp, the exhaust device, and the driving mechanism, so as to facilitate the user to operate the control board to perform the off function operation.

[0020] One or more oil fume filters 11 are detachably installed on the air inlet, so as to facilitate the user to regularly disassemble and clean the oil fume filter.

[0021] An installation bracket 12 is provided on the body 1. Installation holes are reserved on the installation bracket. The installation bracket and the body are installed and fixed by screws and fixed on the ceiling through the installation bracket.

[0022] The exhaust device 4 includes a volute, a turbine and a motor. The turbine is arranged inside the volute. The motor is connected to the turbine to drive it to rotate. An air inlet grille communicating with the inside of the body is opened on the volute.
