Description

Technical Field

[0001] The present invention relates to the field of small household appliances, and in particular to a cooking device heating method, a cooking device, a cooking device and a wall breaking machine. Background Art

[0002] Blenders, soymilk machines, health pots, etc. are all cooking equipment. When processing some ingredients, these cooking equipment usually needs to heat the ingredients to boiling. However, the ingredients in the cooking equipment are easily overflowed after being heated to boiling. On the one hand, the overflow of ingredients will pollute the table, and on the other hand, the overflow of ingredients will cause energy loss, increase the power consumption of the wall breaker, and may also affect the taste of the finished product.

[0003] In order to prevent the ingredients in the cooking equipment from overflowing due to boiling, the first thing to do is to determine the boiling point of the cooking equipment. However, the boiling point varies with altitude and it is difficult to set a fixed value in advance. Therefore, determining the boiling point of the cooking equipment is the key to improving the user experience.

[0004] There are several methods for judging boiling point in existing cooking equipment. The first method is that the user switches to high-altitude mode or normal mode when using it for the first time; the second method is that the cooking equipment itself determines boiling point by detecting that the temperature does not rise within a predetermined time period. The first method requires manual operation by the user, and there are only two modes, which is not accurate enough to judge the boiling point. The second method is not proactive and will still cause overflow of the cooking equipment.

[0005] It can be seen that the method of judging the boiling point of cooking equipment in the prior art is difficult to meet the needs of users. Summary of the invention

[0048] Figure 3 4 is a structural block diagram of a heating device for cooking equipment according to an embodiment of the present invention. DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Figure 1FIG. 1 is an application environment diagram of a cooking device heating method in an embodiment. Figure 1 , the cooking device heating method is applied to cooking equipment.

[0051] Figure 1 The wall-breaking machine shown is a type of cooking device. The cooking device of the embodiment of the present invention can also be a soybean milk machine, a cooking machine, a steaming pot, a health pot, etc., which will not be described in detail here.

[0052] Figure 2 The flowchart of the cooking device heating method according to the embodiment of the present invention is shown, and the method comprises:

[0053] Step 210, periodically obtaining the inner cavity air pressure through the air pressure sensor;

[0054] Step 220, determining whether the inner cavity air pressure is greater than the average air pressure;

[0055] Step 230, if the inner cavity air pressure in the current cycle is greater than the inner cavity average air pressure, and the inner cavity air pressure in the next cycle is less than or equal to the inner cavity average air pressure, then confirm that the air pressure fluctuates once;

[0056] Step 240, obtaining the total number of air pressure fluctuations within a preset time period;

[0057] Step 250: If the total number of inner cavity air pressure fluctuations within the preset time period is greater than or equal to the preset number, it is confirmed that the cooking device is in the boiling stage.

[0058] In actual applications, after the liquid inside the cooking device is heated, it will gradually reach the boiling point and boil. During the entire process from heating at room temperature to boiling, the liquid will vaporize into gas due to reaching the boiling point, causing the air pressure in the closed / relatively closed space to rise. The liquid continues to boil, and the air pressure continues to rise, which will cause the liquid to overflow. Since the volume of the liquid inside the cooking device is unknown, the maximum air pressure inside the cooking device is difficult to determine. Therefore, in the embodiment of the present invention, the gas pressure rising to a certain value is not used to determine whether the inside of the cooking device is boiling, nor is the temperature that changes with the altitude used to make the judgment. Instead, the air pressure fluctuation is used to make the judgment.

[0059] In the embodiment of the present invention, the air pressure rises, and the cooking device is not completely sealed, and a pressure vent hole is provided, or the top cover is opened, so that the inside and outside of the cooking device are connected, and the air pressure drops. In the embodiment of the present invention, the air pressure rises, and the air pressure makes the inside and outside of the cooking device connected, and the air pressure drops, which is recorded as one air pressure fluctuation. If the total number of air pressure fluctuations within the preset time period is greater than or equal to the preset number of times, it is confirmed that the cooking device is in a boiling state.

[0060] In the method of the embodiment of the present invention, the preset number of times can be set to 20 times, 30 times, etc., to avoid misjudgment caused by a single increase in air pressure. In the embodiment of the present invention, the total number of air pressure fluctuations is used to determine whether the cooking equipment is boiling, and boiling can be automatically determined without distinguishing the altitude of the use occasion, thereby improving the user experience. In addition, in the method of the embodiment of the present invention, since the liquid begins to vaporize when the temperature rises to the boiling point, the air pressure rises, and continuous boiling for a period of time will cause overflow. In the embodiment of the present invention, when the liquid just reaches the boiling point, it can be determined whether it has reached the boiling point by the total number of air pressure fluctuations, so that subsequent boiling processing can be performed, which has a certain degree of foresight and can avoid overflow of the cooking equipment.

[0061] In the embodiment of the present invention, Figure 1 As shown, a micro-pressure cover sheet 120 is provided in the inner cavity of the cooking device.

[0062] The micro-pressure cover sheet 120 is disposed adjacent to the air pressure sensor 110. The micro-pressure cover sheet 120 includes an open state and a closed state. When the micro-pressure cover sheet 120 is in the closed state, the inner cavity of the cooking device is isolated from the outside of the cooking device.

[0063] When the micro-pressure cover 120 is in the open state, the inner cavity of the cooking device is communicated with the outside of the cooking device.

[0064] The micro-pressure cover piece 120 may be circular, and a part of the circle is connected to the top cover of the cooking device through a movable connector, a hinge connector, etc., so that the micro-pressure cover piece 120 can be pushed open relatively easily.

[0065] The method further comprises:

[0066] If the first pressure on the micro-pressure cover sheet 120 is greater than the second pressure, the micro-pressure cover sheet 120 is in an open state, so that the inner cavity of the cooking device is connected to the outside, and the air pressure in the inner cavity of the cooking device decreases;

[0067] The first pressure is the pressure exerted on the micro-pressure cover sheet 120 by the inner cavity air pressure of the cooking device, and the second pressure is the sum of the pressure exerted on the micro-pressure cover sheet 120 by the external air pressure of the cooking device and the gravity exerted on the micro-pressure cover sheet 120.

[0068] In the embodiment of the present invention, when the first upward pressure is greater than the second downward pressure, the micro-pressure cover will be pushed open, that is, it is in an open state, so that the inner cavity of the cooking device is connected to the outside. After the inner cavity of the cooking device is connected to the outside, the internal and external air pressures of the cooking device are balanced, and under the action of its own gravity, the micro-pressure cover will fall, that is, it is in a closed state until it is pushed open next time.

[0069] The micro-pressure cover switches between an open state and a closed state. The air pressure detected by the air pressure sensor near the micro-pressure cover is low pressure when it is open and high pressure when it is closed, that is, the air pressure fluctuates. By recording the total number of fluctuations of the micro-pressure cover within a preset time period, it can be determined whether the inside of the cooking device is boiling.

[0070] In addition, the total number of air pressure fluctuations within the preset time period is also related to the boiling time of the cooking equipment. During the initial boiling, the total number of air pressure fluctuations is small, and when the boiling lasts for a long time, the total number of air pressure fluctuations is large.

[0071] In an embodiment of the present invention, before periodically acquiring the inner cavity air pressure through the air pressure sensor, the method further includes:

[0072] obtaining a heater temperature of the cooking device;

[0073] If the heater temperature is lower than the first temperature, multiple air pressures of the inner cavity of the cooking device are continuously acquired at interval sampling time, and an average value of the multiple air pressures is used as the average air pressure.

[0074] The heater is used to heat the food inside the cooking device. The temperature of the heater can be regarded as the temperature of the food inside the cooking device. Usually the first temperature can be set to 60-70 degrees. When the temperature is lower than the first temperature, the air pressure inside the cooking device is basically the same as the local atmospheric pressure, or the air pressure is slightly higher than the local atmospheric pressure because of the closed / semi-closed inner cavity. At this time, the average air pressure value obtained through multiple tests can be more objective.

[0075] In the embodiment of the present invention, the periodic acquisition of the inner cavity air pressure by the air pressure sensor includes:

[0076] obtaining a heater temperature of the cooking device;

[0077] If the heater temperature is greater than the first temperature and less than the second temperature, the inner cavity air pressure is periodically acquired through the air pressure sensor.

[0078] In an embodiment of the present invention, the second temperature can be set to 80-90 degrees. Below the second temperature, there is no need to periodically obtain the inner cavity air pressure, and the air pressure sensor can be in a standby state or a dormant state to reduce the overall power consumption of the cooking device.

[0079] In the embodiment of the present invention, after confirming that the cooking device is in the boiling stage, the method further includes:

[0080] Reduce the heater power to the third power.

[0081] In the embodiment of the present invention, after confirming that the cooking device is in the boiling stage, the method further includes:

[0082] The heater power is reduced according to the total number of air pressure fluctuations within a preset time period;

[0083] The greater the total number of air pressure fluctuations within the preset time period, the smaller the power of the heater will be after reduction.

[0084] In the embodiment of the present invention, if the temperature of the heater is lower than the first temperature, the power of the heater is adjusted to the first power;

[0085] If the temperature of the heater is greater than the first temperature and less than the second temperature, adjusting the power of the heater to the second power;

[0086] The first power is greater than the second power, and the second power is greater than the third power.

[0087] In the embodiment of the present invention, the power varies during the entire cooking process. The temperature of the heater can be considered as the temperature of the food in the inner cavity of the cooking device.

[0088] When the temperature of the heater is lower than the first temperature, the power of the heater is the first power, which may be the maximum power or full power of the cooking device. When the temperature of the heater is higher than the first temperature and lower than the second temperature, the power of the heater is the second power, which may be half to two-thirds of the full power. After the temperature of the heater is higher than the second temperature, the embodiment of the present invention provides two methods, the first is to directly increase the power to the third power, and the second is to reduce the power according to the total number of air pressure fluctuations within a preset time period.

[0089] The third power may be one-third or one-quarter of the full power. The greater the total number of air pressure fluctuations within the preset time period, the smaller the power of the heater after reduction, and the reduction may be in steps, for example, if the total number of fluctuations is 30 times, it is reduced to one-third of the full power, and if the total number of fluctuations is 40 times, it is reduced to one-quarter of the full power.

[0090] In the method of the embodiment of the present invention, the cooking device determines whether boiling occurs by the total number of air pressure fluctuations within a preset time period, and the boiling point can be determined in advance. The boiling point determination is not affected by the altitude, and the determination is accurate. The method of the embodiment of the present invention adjusts the power after determining the boiling point, which can avoid overflow of the cooking device.

[0102] The first pressure is the pressure exerted on the micro-pressure cover sheet by the inner cavity air pressure of the cooking device, and the second pressure is the sum of the pressure exerted on the micro-pressure cover sheet by the external air pressure of the cooking device and the gravity exerted on the micro-pressure cover sheet.
