Description

Range hood, range hood cleaning device and control method thereof

Technical Field

The present invention relates to the technical field of household appliances, and in particular to a range hood cleaning device, a range hood, a control method for the range hood cleaning device, and a non-temporary computer-readable storage medium.

Background Art

After the range hood has been working for a long time, more and more oil will accumulate inside it, resulting in a decline in its performance (such as increased noise, reduced air volume, increased power consumption, etc.). At the same time, bacteria and mold colonies are easily generated inside it. Therefore, the range hood needs to be cleaned after working for a period of time.

Currently, the main cleaning methods for range hoods on the market include hot water cleaning and steam cleaning. Hot water cleaning, due to its low temperature, is less effective in cleaning grease. Furthermore, since the water undergoes no phase change during heating, its volume change is minimal, and the impact force relies solely on the high flow rate provided by the pump, resulting in low cleaning pressure. Steam cleaning, on the other hand, requires the nozzle to be very close to the cleaning surface, while also making it difficult to maintain a high cleaning temperature. Therefore, the cleaning effectiveness of these cleaning methods for range hoods still needs to be improved.

The present invention aims to at least partially address one of the above-mentioned technical problems. To this end, one object of the present invention is to provide a range hood cleaning device that not only provides a high cleaning pressure but also a high cleaning temperature with a slow decay, thereby significantly improving the range hood cleaning effect.

DETAILED DESCRIPTION

The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

The range hood, the range hood cleaning device and the control method thereof according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG1 is a block diagram of a range hood cleaning device according to an embodiment of the present invention.

As shown in FIG1 , the range hood cleaning device according to an embodiment of the present invention includes a water pump 100 , a heating assembly 200 , a temperature sensor 300 , a nozzle 400 and a control module 500 .

Among them, the water pump 100 is used to extract cleaning liquid when it is turned on; the heating component 200 is connected to the water pump 100; the temperature sensor 300 is set corresponding to the heating component 200, and the temperature sensor 300 is used to detect the temperature of the heating component 200; the nozzle 400 is connected to the heating component 200; the control module 500 is respectively connected to the water pump 100, the heating component 200 and the temperature sensor 300, and the control module 500 controls the heating component 200 to heat when the range hood starts the cleaning program, and after the temperature of the heating component 200 reaches the first preset temperature for the first time, controls the water pump 100 to turn on the first preset time and turn off the second preset time in each cleaning cycle, wherein, when the water pump 100 is turned on, the cleaning liquid is pumped into the heating component 200 for heating to generate a high-temperature and high-pressure water vapor mixture, and the water vapor mixture is sprayed out by the nozzle 400 to clean the range hood.

As shown in Figure 2 , the cleaning device according to this embodiment of the present invention may further include a water cup 600 for storing a cleaning fluid, such as water, oil-decomposition fluid, or a mixture of water and oil-decomposition fluid. As shown in Figure 3 , the inlet of the water pump 100 may be connected to the water cup 600 via a first water pipe 01 , so that the cleaning fluid can be drawn from the water cup 600 when the water pump 100 is turned on.

As shown in Figures 2 and 3, the heating assembly 200 may include a liquid storage chamber 210 and a heating element 220 arranged corresponding to the liquid storage chamber 210. The inlet of the liquid storage chamber 210 is connected to the water pump 100 through the second water pipe 02, and the outlet of the liquid storage chamber 210 is connected to the joint 211 through the third water pipe 03 so as to be connected to the nozzle 400.

As shown in FIG2 , the cleaning device according to an embodiment of the present invention may further include a pressure relief valve 700 , which is disposed between the water pump 100 and the inlet of the liquid storage chamber 210 so as to open and release pressure when the pressure within the liquid storage chamber 210 exceeds a pressure threshold. In a specific embodiment of the present invention, the pressure relief valve 700 may be integrated within the water pump 100 or at the outlet of the water pump 100 .

As shown in FIG3 , the control module 500 can be disposed on a control panel. The control module 500 can be connected to the water pump 100 via a first power line 04 and to the heating assembly 200 via a second power line 05 to provide power to the water pump 100 and the heating assembly 200. The control module 500 is also connected to the temperature sensor 300 via a wire 06 to provide power to the temperature sensor 300 and receive the temperature detected by the temperature sensor 300.

In one embodiment of the present invention, the control module 500 may include a timer and a power supply unit, wherein the timer is used to time the first preset time, the second preset time and the duration of the cleaning program; the power supply unit is connected to the heating element 220 and the water pump 100 respectively, wherein the power supply unit controls the heating element to start heating by supplying power to the heating element 220, and controls the water pump 100 to start or stop supplying power to the water pump 100.

Specifically, when the range hood starts the cleaning process, the power supply unit in the control module 500 can supply power to the heating element 220 to control the heating element 220 to turn on and heat the liquid storage chamber 210. As shown in Figure 4, the heating element 220 is continuously turned on throughout the cleaning process.

The temperature sensor 300 can detect the temperature of the heating element 220 or the liquid storage chamber 210. As shown in Figure 4, after the heating element 220 is turned on, the temperature of the heating element 200 detected by the temperature sensor 300 continues to rise. When the temperature of the heating element 200 first reaches a first preset temperature, or temperature t, the power supply unit in the control module 500 can power the water pump 100, controlling the water pump 100 to start pumping cleaning fluid into the liquid storage chamber 210. Because the temperature of the heating element 200 reaches the first preset temperature, i.e., the temperature of the liquid storage chamber 210 is relatively high, the cleaning fluid can instantly vaporize and expand when pumped into the liquid storage chamber 210, generating a mixture of high-pressure steam and high-temperature liquid cleaning fluid, i.e., a water-vapor mixture. As shown in Figure 2, the nozzle 400 includes multiple nozzles 410. Under high pressure, the high-pressure steam and high-temperature liquid cleaning fluid are sprayed through the nozzles 410 to the desired location within the range hood. The heat carried by the high-temperature liquid cleaning fluid reduces heat loss from the steam during the injection process, while the steam's impact force, or cleaning pressure, is high, effectively cleaning the range hood through the water-vapor mixture. As shown in Figure 4, the cleaning pressure, or the pressure in the liquid storage chamber 210, increases as the cleaning fluid is instantaneously heated and decreases as the water-vapor mixture is ejected. The first preset temperature is a temperature at which the cleaning fluid, when pumped into the liquid storage chamber 210, instantly vaporizes and expands, generating high-pressure steam and high-temperature liquid cleaning fluid. In one embodiment of the present invention, the first preset temperature is 120-160°C.

It should be understood that as the cleaning liquid continues to enter, the temperature of the liquid storage chamber 210 may decrease as the cleaning liquid absorbs heat. That is, as shown in Figure 4, after the water pump 100 is turned on for a period of time, the temperature of the heating component 200 may show a downward trend. When the temperature of the heating component 200 is low, the cleaning pressure may be difficult to meet the cleaning requirements. Therefore, in an embodiment of the present invention, when the on time of the water pump 100 reaches the first preset time T1 as measured by the timer, the water pump 100 can be controlled to be turned off so that the temperature of the heating component 200 rises again. After maintaining the closed state of the water pump 100 and the timer reaches the second preset time T2, the water pump 100 can be controlled to be turned on again to increase the cleaning pressure again to spray high-pressure steam and high-temperature liquid cleaning liquid to the position in the range hood that needs to be cleaned, thereby cleaning the range hood.

Furthermore, as shown in FIG4 , the time period T from when the temperature of the heating component 200 first reaches the first preset temperature to when the cleaning program ends may include multiple cleaning cycles. Each cleaning cycle may be divided into a first preset time T1 and a second preset time T2, and the water pump 100 may be controlled to turn on during the first preset time T1 and to turn off during the second preset time T2. In other words, the above-mentioned process of controlling the water pump 100 to turn on for the first preset time T1 and to turn off for the second preset time T2 may be cyclically executed to achieve pulse cleaning of the range hood. In a specific embodiment of the present invention, the first preset time is 1 to 3 seconds, the second preset time is 3 to 8 seconds, and the duration of the cleaning program is 4 to 12 minutes. The entire cleaning program may include 20 to 160 cleaning cycles, that is, 20 to 160 pulse cleanings may be performed during the entire cleaning program.

In other embodiments of the present invention, the water pump 100 may be controlled to turn on whenever the temperature of the heating assembly 200 reaches a first preset temperature, and to turn off when the water pump 100 has been on for a first preset time. In this way, there is no need to count the second preset time, and the cleaning cycle can be determined based on the temperature of the heating assembly 200 and the first preset time.

According to the cleaning device of the range hood according to the embodiment of the present invention, the control module is respectively connected to the water pump, the heating component and the temperature sensor. The control module controls the heating component to heat when the range hood starts the cleaning program, and after the temperature of the heating component reaches the first preset temperature for the first time, controls the water pump to turn on the first preset time and turn off the second preset time in each cleaning cycle. When the water pump is turned on, the cleaning liquid is pumped into the heating component for heating to generate a high-temperature and high-pressure water vapor mixture, and the water vapor mixture is sprayed out by the nozzle to clean the range hood. As a result, not only the cleaning pressure is large, but also the cleaning temperature is high and decays slowly, which can greatly improve the cleaning effect of the range hood.

Corresponding to the above embodiment, the present invention further provides a range hood.

The range hood of the embodiment of the present invention includes the range hood cleaning device proposed in the above embodiment of the present invention. Its specific implementation method can refer to the above embodiment and will not be described again here to avoid redundancy.

According to the range hood of the embodiment of the present invention, the cleaning device thereof not only has a high cleaning pressure, but also has a high cleaning temperature with a slow decay, thus achieving a better cleaning effect.

Corresponding to the above embodiment, the present invention further provides a control method for a cleaning device of a range hood.

Referring to the above embodiments and Figures 1 to 3, the cleaning device of the embodiment of the present invention includes a water pump, a heating component, a temperature sensor and a nozzle. The water pump is used to extract cleaning fluid when it is turned on. The heating component is connected to the water pump. The temperature sensor is set corresponding to the heating component. The temperature sensor is used to detect the temperature of the heating component. The nozzle is connected to the heating component.

As shown in FIG5 , the control method of the range hood cleaning device according to the embodiment of the present invention includes the following steps:

S1, controls the heating component to heat when the range hood starts the cleaning program.

S2, after the temperature of the heating component reaches the first preset temperature for the first time, the water pump is controlled to be turned on for the first preset time and off for the second preset time in each cleaning cycle, wherein when the water pump is turned on, the cleaning liquid is pumped into the heating component for heating to generate a high-temperature and high-pressure water vapor mixture, and the water vapor mixture is sprayed out from the nozzle to clean the range hood.

In one embodiment of the present invention, the heating assembly includes a liquid storage chamber and a heating element arranged corresponding to the liquid storage chamber. The inlet of the liquid storage chamber is connected to the water pump, and the outlet of the liquid storage chamber is connected to the nozzle.

Specifically, when the range hood starts the cleaning program, power can be supplied to the heating element to control the heating element to turn on and heat the liquid storage chamber. As shown in Figure 4, the heating element is continuously turned on during the entire cleaning program.

The temperature sensor detects the temperature of the heating element or the liquid reservoir. As shown in Figure 4, after the heating element is turned on, the temperature of the heating element detected by the temperature sensor continues to rise. When the temperature of the heating element first reaches a first preset temperature, or temperature t, the water pump is powered to control the pump to start pumping cleaning fluid into the liquid reservoir. Because the temperature of the heating element reaches the first preset temperature, i.e., the temperature of the liquid reservoir is relatively high, the cleaning fluid can instantly vaporize and expand when pumped into the reservoir, generating high-pressure steam and high-temperature liquid cleaning fluid, i.e., a water-vapor mixture. As shown in Figure 2, the nozzle includes multiple nozzles. Under high pressure, the high-pressure steam and high-temperature liquid cleaning fluid are sprayed through the nozzles to the desired location within the range hood. The heat carried by the high-temperature liquid cleaning fluid reduces heat loss during the steam injection process, while the steam's impact force, i.e., the cleaning pressure, is relatively high. This allows the water-vapor mixture to effectively clean the range hood. As shown in Figure 4, the cleaning pressure, i.e., the pressure in the liquid reservoir, increases as the cleaning fluid is instantaneously heated and decreases as the water-vapor mixture is ejected. Among them, the first preset temperature is the temperature at which the cleaning liquid can be instantly vaporized and expanded when pumped into the liquid storage chamber, generating high-pressure steam and high-temperature liquid cleaning liquid. In a specific embodiment of the present invention, the first preset temperature is 120-160°C.

It should be understood that as the cleaning liquid continues to enter, the temperature of the liquid storage chamber may decrease as the cleaning liquid absorbs heat. That is, as shown in Figure 4, after the water pump is turned on for a period of time, the temperature of the heating component may show a downward trend. When the temperature of the heating component is low, the cleaning pressure may be difficult to meet the cleaning requirements. Therefore, in an embodiment of the present invention, when the water pump is turned on for a first preset time T1, the water pump can be controlled to be turned off so that the temperature of the heating component rises again. After maintaining the water pump in the closed state for a second preset time T2, the water pump can be controlled to be turned on again so that the cleaning pressure is increased again to spray high-pressure steam and high-temperature liquid cleaning liquid to the location in the range hood that needs to be cleaned, thereby cleaning the range hood.

Furthermore, as shown in FIG4 , the time period T from the first time the temperature of the heating component reaches the first preset temperature to the end of the cleaning program may include multiple cleaning cycles, and each cleaning cycle may be divided into a first preset time T1 and a second preset time T2, and the water pump is controlled to be turned on during the first preset time T1, and to be controlled to be turned off during the second preset time T2. In other words, the above-mentioned process of controlling the water pump to turn on for the first preset time T1 and to turn off for the second preset time T2 may be cyclically executed to achieve pulse cleaning of the range hood. In a specific embodiment of the present invention, the first preset time is 1 to 3 seconds, the second preset time is 3 to 8 seconds, and the duration of the cleaning program is 4 to 12 minutes. The entire cleaning program may include 20 to 160 cleaning cycles, that is, 20 to 160 pulse cleanings may be performed during the entire cleaning program.

In other embodiments of the present invention, the water pump may be controlled to turn on whenever the temperature of the heating component reaches a first preset temperature, and to turn off when the water pump has been on for a first preset time. In this way, there is no need to count the second preset time, and the cleaning cycle can be determined based on the temperature of the heating component and the first preset time.

According to the control method of the cleaning device of the range hood according to the embodiment of the present invention, when the range hood starts the cleaning program, the heating component is controlled to heat, and after the temperature of the heating component reaches the first preset temperature for the first time, the water pump is controlled to open for the first preset time and close for the second preset time in each cleaning cycle, wherein when the water pump is turned on, the cleaning liquid is pumped into the heating component for heating to generate a high-temperature and high-pressure water vapor mixture, and the water vapor mixture is sprayed out from the nozzle to clean the range hood. As a result, not only the cleaning pressure is large, but also the cleaning temperature is high and decays slowly, thereby greatly improving the cleaning effect of the range hood.
