Description

Technical Field

[0001] The invention relates to a wind cabinet cleaning method and a household appliance. Background Art

[0002] Range hoods and integrated stoves are commonly used in daily life, but since a large area of ​​​​our country has the habit of eating animal oil, especially in the winter in the north, the fumes produced by animal oil stick to the wind cabinet and wind impeller and easily form solid grease after pre-cooling, which is difficult to remove. This increases the load on the wind impeller and motor, affects the dynamic balance of the wind impeller, reduces the wind speed and air volume, and even causes damage to the motor and requires after-sales service. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a wind cabinet cleaning method and a household appliance, aiming to provide a structure for conveniently cleaning the solidified grease on the wind wheel wind cabinet.

[0005] S1. When the motor stops, the fan and the heating element work and blow hot air into the wind cabinet for a set time to melt the solidified grease in the wind wheel and the wind cabinet, and some large pieces or large grease drips and enters the oil leakage hole of the wind cabinet;

[0006] S2. When the motor stops, the fan stops, the heating element works to heat the water in the waterway, and after a set time, the water pump works to spray hot water or hot water mist to the wind wheel, so that the wind wheel is covered with hot water to dissolve the melted grease;

[0007] S3. Slowly start the motor, and the water with grease on the wind wheel is thrown toward the inner wall of the wind cabinet under the action of centrifugal force, and at the same time slides down along the inner wall of the wind cabinet and takes away the residual grease on the wind cabinet;

[0008] S4. Repeat S2 and S3 to remove the residual grease on the wind cabinet;

[0009] S5. After the motor is stopped and the fan and the heating element work simultaneously for a set time, the wind wheel and the wind cabinet are dried.

[0010] The water pump sprays water to the wind wheel to dissolve and clean the solidified grease. At the same time, the fan blows hot air to the wind cabinet and wind wheel to dissolve the fixed grease, increase the speed of removing the solidified grease, and form automatic cleaning. There is no need for manual work to reach into the wind cabinet to remove and clean the solidified grease.

[0011] In one or more embodiments, the water pump provides hot water or room temperature water to the wind wheel. In summer, the water pump in S2 sprays hot water or hot water mist or room temperature water or room temperature water mist to the wind wheel.

[0012] In one or more embodiments, when the water pump provides hot water to the wind wheel, it is used to dissolve the oil stains in the wind cabinet; when the water pump provides room temperature water to the wind wheel, it is used to clean the wind wheel.

[0013] In one or more embodiments, the fan provides hot air to the wind cabinet to dissolve oil stains on the wind wheel and the wind cabinet or to dry the wind wheel and the wind cabinet.

[0014] In one or more embodiments, a nozzle is provided at the outlet of the water channel to form a droplet-shaped spray or water mist to prevent impact on the wind wheel and affect the dynamic balance of the wind wheel, while being able to form a large-area spray so that the wind wheel is quickly covered with droplets.

[0015] In one or more embodiments, the heating element is a PTC heating element or a heating tube.

[0016] In one or more embodiments, a flow meter is also provided on the water channel, and a temperature probe is provided at a position on the wind wheel corresponding to the water outlet. The flow meter and the temperature probe are also electrically connected to the control device. After the water pump is started for a set time, the control device determines whether there is water in the water storage chamber based on the flow data and the temperature data change of the temperature probe and controls whether to issue an alarm. When the flow data is lower than the set value and the temperature data of the temperature probe does not change, the control device determines that there is no water in the water storage chamber and issues an alarm. When the flow data of the temperature probe is equal to or higher than the set value and the temperature data of the temperature probe changes, the control device determines that there is water in the water storage chamber and does not issue an alarm. This can intuitively inform the user that there is insufficient water in the water storage chamber and that water needs to be added. The system is highly automated and user-friendly.

[0017] In one or more embodiments, a temperature detection device for checking the temperature of the heating element is also provided on the heating element. The temperature detection device is electrically connected to the control device. When the temperature value of the temperature detection device is higher than the set value, the control device sends out an alarm, which can intuitively inform the user that the heat of the heating element is too high and heating needs to be stopped. The system is highly automated and user-friendly.

[0018] In one or more embodiments, the water channel is wound around the heating element.
