As shown in fig. 1 to 6, a range hood is taken as an example, and a control board 2 mounting assembly for a range hood according to the present utility model will be described.

Referring to fig. 1 to 6, the range hood includes a body 1, a blower system 15, a smoke baffle 13, and a control panel 2 mounting assembly.

The machine body 1 comprises a fume collecting hood 11 and a fan frame 12, wherein the fume collecting hood 11 is arranged at the bottom of the fan frame 12 and is communicated with the inside of the fan frame 12. The front side wall of the fume collecting hood 11 is inclined backward from top to bottom, specifically, the front side wall of the fume collecting hood 11 is provided with air inlets 14 extending in the left-right direction. The fan system 15 is a centrifugal fan, which is disposed inside the fan housing 12 and the fume collecting hood 11 and is inclined backward from top to bottom. The centrifugal fan includes a scroll 151, an impeller 152, and a motor 153, and the impeller 152 is provided inside the scroll 151 and is driven to rotate by the motor 153. An air suction port is formed in the front side wall of the volute 151, and the air suction port is opposite to the air inlet 14 in the front side wall of the fume collecting hood 11.

The smoke baffle 13 is a strip-shaped plate matched with the air inlet 14 of the smoke collecting hood 11, and the smoke baffle 13 is rotationally connected at the upper side edge of the air inlet 14 of the smoke collecting hood 11 by taking the upper side edge as a rotation axis and can open or close the air inlet 14 of the smoke collecting hood 11.

The smoke barrier 13 of the present embodiment includes a glass plate 131 and a back plate bracket 132 attached to the back surface of the glass plate 131.

The control board 2 mounting assembly includes a control board 2, a protective case 3, a sealing member 4, and an air supply device.

The protective case 3 is in the form of a case body open at the side. When installed, the opening of the protection box 3 faces the back plate bracket 132 of the smoke baffle 13, and can be connected to the back plate bracket 132 by screws. The protective case 3 and the corresponding region on the back plate bracket 132 define together a housing chamber 30 for accommodating the control board 2 in the mounted state of the protective case 3. The sealing member 4 is annular in shape as a whole and can be clamped between the open peripheral edge of the shield case 3 and the back plate bracket 132 to ensure tightness at the joint position between the two.

The seal 4 of the present embodiment employs a deformable rubber member that includes a seal body 41, an inner Zhou Chunbian 421 and an outer Zhou Chunbian 422.

The inner Zhou Chunbian of the seal 4 extends inwardly from the seal body 41, the outer Zhou Chunbian extends inwardly from the seal body 41, the outer Zhou Chunbian 422 is disposed at an angle to the inner Zhou Chunbian 421 and the outer Zhou Chunbian such that the cross section of the seal 4 is generally V-shaped with the opening toward the backplate support 132, such that when the seal 4 is initially installed between the guard and backplate support 132, the edges of the inner Zhou Chunbian 421 and the outer Zhou Chunbian of the seal 4 contact the backplate support 132 and together form a space that allows the inner Zhou Chunbian 421 and outer Zhou Chunbian of the seal 4 to continue to be concavely deformed toward the backplate support 132.

The inner part Zhou Chunbian 421 of the sealing element 4 protrudes into the receiving chamber 30, i.e. forms the sealing lip of the present embodiment. The air supply device is used for increasing air supply into the accommodating chamber 30, after the air pressure of the accommodating chamber 30 is increased to a certain extent, the sealing lip extending into the accommodating chamber 30 can be tightly attached to the back plate bracket 132 under the action of air pressure, and even if the number of screws for fixing the protection box 3 is small (the initial uneven stress on the circumference of the sealing element 4 is caused), the sufficient sealing effect can be ensured.

The air supply device comprises an air supply pipeline 5, a control valve 51, a pressure sensor, a pneumatic booster and a controller. The control valve 51 is provided on the air supply line 5, and is used for controlling the on-off of the air supply line 5. In order to further ensure the stability of the air supply pressure maintaining of the air supply line 5, the control valve 51 of the present embodiment is a one-way throttle valve.

The inlet of the air supply pipeline 5 is communicated with the air outlet of the volute 151, and the outlet of the air supply pipeline 5 is communicated with the accommodating chamber 30, so that when the centrifugal fan operates, air can be supplied into the accommodating chamber 30 by opening the control valve 51. In view of the limited air pressure provided by the fan system 15 alone, in particular in low wind speed gear, in order to ensure sufficient air pressure in the receiving chamber 30, the air supply line 5 is also provided with a pneumatic booster, wherein the pneumatic booster may be a VBA series pneumatic booster from the company SMC of japan,

a pressure sensor (not shown) is provided on the shield case 3 for detecting the air pressure in the accommodating chamber 30. The protection box 3 of this embodiment is formed by integrally stretching metal plates, and the pressure sensor is arranged on the protection box 3, so that the fixation is firmer.

The controller is electrically connected with the pressure sensor and the control valve 51, and can control the opening and closing of the control valve 51 according to pressure signals transmitted by the pressure sensor. Specifically, the controller analyzes and acquires a pressure signal from the pressure sensor, opens the control valve 51 when the pressure value is smaller than the set value, thereby ventilating and pressurizing the inside of the accommodating chamber 30, and closes the control valve 51 when it is detected that the pressure value is larger than the set value. Of course, if the control valve 51 is opened to vent and pressurize, the pressure value can not reach the set value (or a relatively long time is needed to reach the set value), and the sealing ring may fail, or other parts have poor sealing, the sealing ring needs to be replaced or other parts need to be detected, so that the damage caused by the water inlet of the components on the control panel 2 is prevented.

In this embodiment, the sealing piece 4 disposed between the protective case 3 and the component to be mounted has a sealing lip capable of extending into the accommodating chamber 30, and after the air supply device ventilates and pressurizes the accommodating chamber 30, the sealing lip of the sealing piece 4 can be pressed on the component to be mounted under the action of air pressure, and because the sealing lip of the sealing piece 4 is integrally pressed on the component to be mounted, the circumferential stress is more uniform, and the sealing effect between the protective case 3 and the component to be mounted is ensured.
