Detailed ways

Embodiments of the present invention are described in detail below, embodiments of which are illustrated in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

In the description of the embodiments of the present invention, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it may be a detachable connection or an integral connection; it may be a mechanical connection, It can also be electrically connected or can communicate with each other; it can be directly connected or indirectly connected through an intermediary. Those of ordinary skill in the art can understand the specific meanings of the above terms in the embodiments of the present invention according to specific situations.

Referring to FIG. 1 , an embodiment of the present invention provides a control method for a kitchen appliance 100 . The control method includes the following steps:

Step S10, obtaining the temperature information of the kitchen and the gas composition information of the kitchen;

Step S20, determine whether to turn on the fan assembly 60 of the kitchen appliance 100 according to the temperature information and the gas composition information;

Step S30, acquiring kitchen humidity information and kitchen dust information;

Step S40, determine whether to adjust the operating parameters of the fan assembly 60 according to the humidity information and the dust information.

The control method of the kitchen appliance 100 according to the embodiment of the present invention first judges whether the user starts cooking according to the temperature information and the gas composition information, so as to control the operation of the fan assembly 60 in time to prevent the oil fume from escaping in the kitchen before turning on the fan assembly 60, and then through Acquire the humidity information and dust information of the kitchen, adjust or keep the operating parameters of the fan assembly 60 unchanged, so that the air volume of the fan assembly 60 matches the oil fume and water vapor content of the kitchen.

Specifically, the temperature information is used to represent the temperature of the kitchen, and the temperature information can represent the temperature of the cooking appliance, because the temperature of the surrounding environment of the cooking appliance will also increase during the cooking process of the user, so the temperature information can also represent the temperature of the cooking appliance. The temperature of the environment surrounding the appliance, eg, the temperature somewhere inside the kitchen appliance 100 .

The gas composition information is used to indicate the gas composition in the kitchen. The gas composition information is related to the cooking fume. During the cooking fume process, specific gases such as polycyclic aromatic hydrocarbons will be produced. Therefore, based on the gas composition information, it can be judged whether the user is Start cooking.

When it is known that the current kitchen temperature rises according to the temperature information and the gas generated by cooking is known according to the gas composition information, it can be considered that the user is cooking, so the fan assembly 60 that is turned on in time, compared with the existing one that only relies on dust information To determine whether to turn on the kitchen appliance of the fan assembly, the embodiment of the present invention can make the operation of opening the fan assembly 60 faster, effectively avoiding the situation that the oil fume has already escaped in the kitchen, and the fan assembly 60 has just started to open.

It is worth noting that after the fan assembly 60 is turned on, the initial operating parameters of the fan assembly 60 can be adjusted according to actual use, simulation results, and the like. In some embodiments, because the cooking fumes are usually not large at the beginning of cooking, the initial operating parameters of the fan assembly 60 can be set relatively small. As the cooking progresses, the cooking fume gradually increases, and the humidity information and dust information are also collected. is completed, so the operating parameters can be increased according to the humidity information and dust information.

Humidity information is used to indicate the humidity of the kitchen. During the cooking process, water vapor will be generated, which will increase the humidity information. The fan assembly 60 can also be used to suck and discharge water vapor to prevent the kitchen from being too humid. Therefore, according to the humidity information , the operating parameters of the fan assembly 60 can be adjusted so that the fan assembly 60 can discharge the water vapor in the kitchen in time.

The dust information is used to represent the particles in the kitchen, and the particles may include soot particles, water vapor, etc. The greater the amount of dust represented by the dust information, the greater the operating parameters required by the fan assembly 60, so that the fan assembly 60 can be adjusted according to the dust information. operating parameters. It is worth noting that, in the case of the same dust information, when there is more water vapor and less soot particles, the operating parameters of the fan assembly 60 can be smaller; Can be larger.

It should be noted that it is possible to determine whether to adjust the operating parameters of the fan assembly 60 based solely on the humidity information or dust information. The air volume of the fan assembly 60, as another example, if the dust information indicates that the kitchen environment has a certain dust content, then it can be determined to adjust the operating parameters of the fan assembly 60 and increase the air volume of the fan assembly 60, because the embodiment of the present invention is based on temperature information and gas Composition information determines whether to turn on the fan assembly 60, and adjusts operating parameters according to the humidity information and dust information, so it can effectively avoid the situation that the fan assembly 60 is turned on by mistake. Turn on the fan assembly 60 by mistake; and for example, when the user uses flour in the kitchen, the fan assembly 60 will not be turned on by mistake because of the dust information.

It is worth noting that it is possible to determine whether to adjust the operating parameters of the fan assembly 60 according to the humidity information and dust information when it is determined to turn on the fan assembly 60 according to the temperature information and the gas composition information. Because usually, the temperature of the kitchen does not rise and the gas produced together with the cooking fume is not detected, it can be inferred that the user is not cooking, so there is no need to adjust the operating parameters of the fan assembly 60 . If the temperature information and gas composition information indicate that the current user is not cooking, but the humidity information exceeds the threshold, an abnormal reminder can be sent to the user, or if the dust information exceeds the threshold, an abnormal reminder can also be sent to the user, so that the user can change the threshold and monitor the sensor. Maintenance and other operations.

The operating parameters of the fan assembly 60 may include data such as air volume, voltage, and current, which are not specifically limited here.

It is worth adding that the kitchen appliance 100 can also be equipped with lamps, air conditioners and other components, and at the same time determine to turn on the fan assembly 60 according to the temperature information and gas composition information, and at the same time determine to turn on the lamps; it can also determine to turn on the air conditioner according to the temperature information , and adjust the operating parameters of the air conditioner according to the temperature information.

In some implementation manners, referring to FIG. 2, step S20 includes:

Step S21, when the temperature information is greater than the first temperature threshold and the gas composition information is greater than the first composition threshold, determine to turn on the fan assembly 60;

Step S23 , if the temperature information is less than the first temperature threshold and/or the gas composition information is less than the first composition threshold, it is determined not to turn on the blower assembly 60 .

Such setting avoids the situation that the fan assembly 60 is turned on incorrectly due to incorrect measurement of temperature information or gas composition information. The temperature information and gas composition information are mutually verified to ensure that the fan assembly 60 is turned on when the user starts cooking.

Specifically, the speed of obtaining temperature information and gas composition information is faster than that of humidity information and dust information. Therefore, determining whether to turn on the fan assembly 60 according to the temperature information and gas composition information can quickly respond to cooking fumes.

There are many kinds of values for the first temperature threshold, which can be set according to actual usage requirements, simulation results, etc., and no specific limitation is set here.

There are many kinds of values of the first component threshold, which can be set according to actual usage requirements, simulation results, etc., and are not specifically limited here.

In some implementations, referring to FIG. 3, the operating parameters of the fan assembly 60 include the air volume. Step S40 includes:

Step S41, increasing the air volume of the fan assembly 60 when the humidity information is greater than the first humidity threshold;

Step S42, when the humidity information is less than the first humidity threshold and greater than the second humidity threshold, keep the air volume of the fan assembly 60 unchanged, and the second humidity threshold is less than the first humidity threshold;

Step S43 , if the humidity information is less than the second humidity threshold, reduce the air volume of the fan assembly 60 .

With such arrangement, the air volume of the fan assembly 60 can be adjusted according to the humidity information, so that the air volume of the fan assembly 60 matches the humidity environment of the kitchen.

Specifically, there are many values of the first humidity threshold and the second humidity threshold, which can be set according to actual usage requirements, simulation results, etc., and are not specifically limited here. The value of the increased air volume or decreased air volume of the fan assembly 60 can be set by the manufacturer during production, or can be set by the user according to the needs of use, which is not specifically limited here.

In some implementations, please refer to FIG. 4, the operating parameters of the fan assembly 60 include the air volume, and step S40 includes:

Step S45, if the dust information is greater than the first dust threshold, increase the air volume of the fan assembly 60;

Step S46, when the dust information is less than the first dust threshold and greater than the second dust threshold, keep the air volume of the fan assembly 60 unchanged, and the second dust threshold is less than the first dust threshold;

Step S47, if the dust information is less than the second dust threshold, reduce the air volume of the fan assembly 60 .

With such arrangement, the air volume of the fan assembly 60 can be adjusted according to the dust information, so that the air volume of the fan assembly 60 matches the dust environment of the kitchen.

Specifically, there are many kinds of values for the first dust threshold and the second dust threshold, which can be set according to actual usage requirements, simulation results, etc., and are not specifically limited here. The value of the increased air volume or decreased air volume of the fan assembly 60 can be set by the manufacturer during production, or can be set by the user according to the needs of use, which is not specifically limited here.

It is worth noting that whether to adjust the operating parameters of the fan assembly 60 can be determined according to the humidity information and the dust information at the same time.

For example, when the humidity information is greater than the first humidity threshold and the dust information is greater than the first dust threshold, increase the air volume of the fan assembly 60; In other cases, keep the air volume of the fan assembly 60 unchanged; for another example, reduce the air volume of the fan assembly 60 when the humidity information is less than the second humidity threshold and the dust information is less than the second dust threshold.

At this time, the specific reduced air volume value or the specific increased air volume value can be calculated by adding or subtracting the air volume value obtained according to the humidity information and the air volume value obtained according to the dust information, and no specific limitation is set here.

It is also possible to determine whether to adjust the operating parameters of the fan assembly 60 according to the humidity information and the dust information respectively.

For example, if the humidity information is obtained first, step S41, step S42 or step S43 is performed according to the humidity information, and after the dust information is obtained, then step S45, step S46 or step S47 is performed according to the dust information.

Specifically, in a certain embodiment, if the humidity information is greater than the first humidity threshold, then according to the humidity information, increase the air volume of the fan assembly 60, and then obtain the dust information less than the second dust threshold, then reduce the fan assembly 60 according to the dust information. The air volume of the assembly 60.

It should be noted that the increased or decreased air volume value based on the humidity information may be the same as or different from the increased or decreased air volume value based on the dust information. In a certain embodiment, the value of the air volume increased according to the dust information is greater than the value of the air volume increased according to the humidity information, then when the dust information is greater than the first dust threshold and the humidity information is less than the second humidity threshold, increase The air volume of the fan assembly 60, and the increased value of the air volume of the fan assembly 60 is the value of the air volume increased according to the dust information minus the value of the air volume increased according to the humidity information.
