[0001] The present invention relates to the technical field of range hoods, and in particular to a range hood and a control method and a control device thereof. Background Art

[0002] Traditional range hoods only have the function of extracting oil smoke. In summer, when users cook in the kitchen, the temperature in the kitchen is relatively high, and the cooking experience is poor. In the related technology, air-conditioning range hoods have appeared. An air-conditioning module is arranged above the range hood body, which will cause the overall height of the range hood to be relatively large and is not suitable for all kitchen spaces. Summary of the invention

[0003] In view of this, the present invention provides a range hood and a control method and a control device thereof to solve the problem of high temperature in the kitchen and poor cooking experience.

[0004] In a first aspect, the present invention provides a range hood, comprising:

[0005] The range hood body has a smoke collecting chamber;

[0006] A fan module is installed on the range hood body and located at the front end of the smoke collecting chamber. The fan module has a top air inlet and a front air outlet. The fan module includes a fan.

[0007] Beneficial effect: By installing a fan module on the main body of the range hood, the fan module is located at the front end of the smoke collecting chamber, the fan module has a top air inlet and a front air outlet, and the fan module includes a fan. When the kitchen temperature is high, the fan module is operated, and air enters from the top air inlet and blows toward the user from the front air outlet, making the user feel cool and improving the cooking experience. In addition, installing the fan module at the front end of the smoke collecting chamber will not increase the overall height of the range hood.

[0008] In an optional embodiment, an air processing module is provided at the top air inlet, and the air processing module is capable of purifying the air.

[0009] Beneficial effect: By setting an air treatment module at the top air inlet of the fan module, the air treatment module can purify the air. After purification, the air is blown to the user from the front air outlet under the action of the fan, making the user feel cool, which can improve the air quality in the kitchen and ensure the health of the user.

[0010] In an optional embodiment, the air processing module includes a mounting bracket and a filter, and the filter is mounted on the mounting bracket.

[0011] Beneficial effects: The filter is installed at the top air inlet through the mounting bracket. The filter can filter and purify the air. After purification, the air is blown to the user from the front air outlet under the action of the fan, making the user feel cool, which can improve the air quality in the kitchen and ensure the health of the user.

[0012] In an optional embodiment, the filter screen is fixed to the mounting bracket by a buckle.

[0013] Beneficial effect: The filter is fixed to the mounting bracket by a buckle, and the assembly method of the filter and the mounting bracket is simple and convenient, which can improve the assembly efficiency.

[0014] In an optional embodiment, the air processing module further includes a heating device, and the heating device is mounted on the mounting bracket.

[0015] Beneficial effect: By setting up a heating device, when the ambient temperature is low, such as in winter, the heating device can be operated to heat the air entering from the top air inlet, and the heated air is blown toward the user from the front air outlet, making the user feel warm.

[0016] In an optional embodiment, the heating device includes an electrical box and heating wires arranged on both sides of the electrical box, a mounting groove is provided in the middle of the mounting bracket, and the electrical box is embedded in the mounting groove.

[0017] Beneficial effect: By setting up the electrical box, the circuit of the heating device can be protected. Electric heating wires are arranged on both sides of the electrical box, which can evenly heat the air entering from the top air inlet.

[0018] In an optional embodiment, the air processing module further includes an electrical box cover, and the electrical box cover is disposed on the electrical box.

[0019] Beneficial effect: The electrical box cover is arranged on the electrical box, and can protect the circuit inside the electrical box.

[0020] In an optional embodiment, the range hood further includes an air quality monitoring component, a reminder component and a controller, wherein the air quality monitoring component is used to detect the quality of air after being filtered by the filter, and the controller is communicatively connected with the reminder component and the air quality monitoring component.

[0021] Beneficial effect: By setting up an air quality monitoring component, the quality of air after being filtered by the filter can be detected. When the quality of air after being filtered by the filter is poor, it means that the filter needs to be cleaned or replaced. At this time, the reminder component sends a prompt message to remind the user to clean or replace the filter.

[0022] In an optional embodiment, the range hood further comprises a temperature monitoring component, wherein the temperature monitoring component is used to detect the ambient temperature, and the temperature monitoring component, the heating device and the fan module are all communicatively connected to the controller.

[0023] Beneficial effect: By setting up a temperature monitoring component, the temperature monitoring component can detect the ambient temperature. When the ambient temperature is high, the fan module can be controlled to open to blow air to the user, making the user feel cool. When the ambient temperature is low, the heating device can be controlled to heat the air and blow hot air to the user.

[0024] In an optional implementation, the height of the fan module is equal to the height of the smoke collecting chamber.

[0025] Beneficial effects: Since the height of the fan module is equal to the height of the smoke collecting chamber, on the one hand, the appearance can be made more beautiful, and on the other hand, the height of the fan module is small and does not occupy a large space.

[0026] In a second aspect, the present invention further provides a control method for a range hood, which is applied to the range hood, and the control method comprises:

[0027] Get air quality parameters;

[0028] Determine whether the air quality parameter is less than the preset value;

[0029] If the air quality parameter is greater than or equal to the preset value, the control reminder component sends a reminder message.

[0030] Beneficial effect: By obtaining air quality parameters, when the air quality parameters are greater than or equal to the preset value, it means that the air quality after filtering by the filter is poor, indicating that the filter needs to be cleaned or replaced. At this time, the reminder component sends a prompt message to remind the user to clean or replace the filter.

[0031] In an optional implementation, the control method further includes:

[0032] Get the ambient temperature;

[0033] If the ambient temperature is within the first temperature range, the heating device is controlled to operate and the fan module is controlled to operate at a first gear.

[0034] Beneficial effect: By obtaining the ambient temperature, when the ambient temperature is within the first temperature range, it means that the ambient temperature is low. At this time, the heating device is controlled to work, and the air entering from the top air inlet is heated. The heated air is blown to the user from the front air outlet, making the user feel warm. At this time, the gear of the fan module is low, which can make the user more comfortable.

[0035] In an optional implementation, the control method further includes:

[0036] If the ambient temperature is within the second temperature range, the fan module is controlled to operate at the second gear;

[0037] If the ambient temperature is within the third temperature range, the fan module is controlled to operate at the third gear.

[0038] Beneficial effect: When the ambient temperature is within the second temperature range, the fan module is controlled to operate at the second gear; when the ambient temperature is within the third temperature range, the fan module is controlled to operate at the third gear. The gear of the fan module is adjusted according to changes in ambient temperature to improve user comfort.

[0039] In an optional implementation, the control method further includes:

[0040] If the ambient temperature is within the fourth temperature range, the control prompt component sends a prompt message.

[0041] Beneficial effect: When the ambient temperature is within the fourth temperature range, it indicates that the ambient temperature is too high. At this time, the control reminder component sends a reminder message to remind the user that the temperature is too high.

[0042] In a third aspect, the present invention further provides a control device for a range hood, which is applied to the range hood, and the control device comprises:

[0043] A first acquisition module is used to acquire air quality;

[0044] The first judgment module is used to judge whether the air quality is less than a preset value;

[0045] The first control module is used to control the reminder component to send a reminder message when the air quality is greater than or equal to a preset value.

[0046] Beneficial effect: By obtaining air quality parameters, when the air quality parameters are greater than or equal to the preset value, it means that the air quality after filtering by the filter is poor, indicating that the filter needs to be cleaned or replaced. At this time, the reminder component sends a prompt message to remind the user to clean or replace the filter. BRIEF DESCRIPTION OF THE DRAWINGS
