[0003] In the process of implementing the embodiments of this disclosure, it was found that at least the following problems exist in the related technology: Traditional kitchen appliances often perform self-cleaning after the device has been running for a set time, according to the set program instructions. In this case, the oil fumes have usually accumulated for a long time, and the cleaning effect is poor. Summary of the Invention

[0004] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0005] This disclosure provides a water pump control method and device, and an integrated stove, to solve the technical problem of how to control the water pumping volume according to the fan speed.

[0006] In some embodiments, the method for controlling the water pump includes:

[0007] Obtain the concentration of cooking fumes;

[0008] The fan speed is controlled by the concentration of oil fumes.

[0009] The pumping rate of the water pump is controlled according to the fan speed.

[0011] In some embodiments, the integrated stove includes a water pump control device as described above.

[0012] The water pump control method, device, and integrated stove provided in this disclosure can achieve the following technical effects: by controlling the fan speed based on the oil fume concentration, and then controlling the water pumping volume based on the fan speed, the equipment can achieve real-time self-cleaning, and the amount of water pumped is matched with the amount of oil fume dirt being cleaned, making the equipment cleaner, and avoiding waste due to excessive water pumping, making the equipment more intelligent and improving the user experience.

[0013] The above general description and the description below are exemplary and illustrative only and are not intended to limit this application. Attached Figure Description

[0014] One or more embodiments are illustrated by way of example with reference to the accompanying drawings. These illustrations and drawings do not constitute a limitation on the embodiments. Elements having the same reference numerals in the drawings are shown as similar elements. The drawings are not to be scaled. And wherein:

[0015] Figure 1 This is a flowchart of a water pump control method provided in an embodiment of this disclosure;

[0016] Figure 2 This is a schematic diagram of the control device for the water pump provided in an embodiment of this disclosure; Detailed Implementation

[0017] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0018] In some embodiments, when the integrated stove is running, oil fumes will adhere to the impeller of the integrated stove fan, producing oil fume dirt. If it is not cleaned in time, it will affect the operating performance of the integrated stove. The cleaning liquid is pumped to the cleaning nozzle by a water pump, and the cleaning liquid is sprayed onto the impeller through the cleaning nozzle. The cleaning liquid reacts with the oil fumes on the impeller to generate oil fume particles. The oil fume particles drip into the oil collection device, which can realize the real-time self-cleaning function of the integrated stove.

[0019] In some embodiments, a water pump draws cleaning water into a heating device, which heats the cleaning water to produce steam. The steam is then sprayed onto the impeller through a cleaning nozzle connected to the heating device, dissolving the oil fumes on the impeller surface into an oil fume solution. The oil fume solution drips into an oil collection device, thus enabling the integrated stove to perform real-time self-cleaning.

[0020] The water pump needs to deliver a matching amount of cleaning agent to ensure that the grease on the impeller is completely cleaned without wasting excessive cleaning agent. When the integrated stove is running, the more grease and fumes there are, the faster the fan needs to rotate to remove them quickly, resulting in more grease and grime. Therefore, controlling the fan speed based on the grease concentration, and then controlling the water pump's delivery volume accordingly, ensures the pump delivers the right amount of water to thoroughly clean the impeller without wasting water. Optionally, the cleaning agent can be a cleaning liquid or cleaning water. Optionally, the cleaning liquid can react with the grease to form grease particles, and the cleaning water can be tap water.

[0023] S102. Control the fan speed by controlling the oil fume concentration;

[0024] S103. Control the pumping volume of the water pump according to the fan speed.

[0025] In some embodiments, the concentration of oil fumes during the operation of the integrated stove is first obtained, then the fan speed during the operation of the integrated stove is controlled by the concentration of oil fumes, and finally, the pumping volume of the water pump is controlled according to the fan speed.

[0026] In some embodiments, obtaining the concentration of cooking fumes includes:

[0027] Acquire images of cooking fumes;

[0028] The concentration of cooking fumes is detected by analyzing images of cooking fumes.

[0029] In some embodiments, before each operation of the integrated stove, an initial image is first acquired by a camera device installed on the integrated stove, and then during the operation of the integrated stove, images of oil fumes are acquired in real time.

[0030] In some embodiments, during the operation of the integrated stove, a detection is performed every time t, that is, an image of oil fume is collected once. Optionally, t is 5 minutes.

[0038] In some embodiments, obtaining the oil fume concentration based on comparison information includes:

[0039] When |X n -Y n When |>S1, then Y n The corresponding pixel is the oil fume pixel, where S1 is the grayscale threshold; S1 > 0; optionally, S2 is 2; the corresponding preset oil fume concentration is matched according to the number of oil fume pixels, as shown in Table 1, which is the preset oil salt concentration matched according to the number of oil fume pixels.

[0053] In some embodiments, the method further includes obtaining the direction of the cooking fumes based on comparison information.

[0054] In some embodiments, obtaining the direction of cooking fumes based on comparison information includes: dividing the cooking fume image into regions; and determining the direction of cooking fumes based on the number of cooking fume pixels in each region.

[0055] In some embodiments, the integrated stove is equipped with multiple fans, each fan corresponding to a water pump. For example, the first fan corresponds to a first water pump, and the second fan corresponds to a second water pump. The oil fume image is divided into a first image region and a second image region. The first image region is the area where the first fan operates, and the second image region is the area where the second fan operates. According to Table 1, the oil fume concentration in the first image region and the second image region is determined by the number of oil fume pixels in the first image region and the second image region, respectively. Then, the rotation speed of the first fan and the second fan is controlled according to the oil fume concentration in the first image region and the second image region, respectively. Finally, the pumping volume of the first water pump and the second water pump is controlled according to the rotation speed of the first fan and the second fan, respectively. By dividing the oil fume image into regions and determining the oil fume concentration in each region, the direction of the oil fume can be determined. The corresponding fan speed is then controlled, and the water pump delivers a matching amount of water for cleaning based on the fan speed. For integrated stoves with multiple fans, targeted self-cleaning operations can be performed based on the fan's operating status. This allows for timely cleaning of the impellers of running fans that have generated oil fume and dirt, while cleaning is not performed on the impellers of non-running fans. This makes the equipment more energy-efficient, reduces power consumption, and improves the accuracy of oil fume detection, making the self-cleaning function of the equipment more rational and intelligent.

[0056] As can be seen from the water pump control method in the above embodiments, the water pump control method provided in this disclosure controls the fan speed by obtaining the oil fume concentration, and then controls the pumping volume of the water pump according to the fan speed. This enables the equipment to self-clean in real time and makes the amount of water pumped match the amount of oil fume and dirt cleaned, thus cleaning the equipment more thoroughly and without causing waste due to excessive water pumping. This makes the equipment more intelligent and improves the user experience.

[0057] This disclosure provides a control device for a water pump, the structure of which is as follows: Figure 2As shown, the system includes a processor 100 and a memory 101 storing program instructions.
