Description

Technical Field

[0001] The present invention belongs to the technical field of cooking equipment control, and in particular relates to an over-temperature steamer and a control method, equipment and medium thereof. Background Art

[0002] An over-temperature steamer is a commonly used cooking device with an over-temperature heating function. At present, there are two conventional design schemes for over-temperature steamers. One is to achieve over-temperature heating by arranging a heating tube in the cavity, and the other is to heat the water inlet through an external heating module, vaporize it at high temperature, and then spray it into the cavity. However, both schemes have shortcomings: arranging a heating tube in the cavity will waste the internal space of the cavity and make the cavity difficult to clean; the external heating module needs to add a water inlet system to heat the water inlet, and it will cause the water vapor to liquefy when it reaches the surface of the food. It is also necessary to add equipment to remove the condensed water on the top of the cavity, which leads to problems such as cumbersome design and high cost. In addition, the over-temperature steamer usually discharges the generated water vapor directly out of the cavity without recycling it, resulting in problems such as high energy consumption and slow heating of the over-temperature steamer.

[0058] The present disclosure is further described below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0059] Example 1

[0060] This embodiment provides an over-temperature steam box, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the over-temperature steam box includes a cavity 1, and an air inlet ratio regulating valve 2, a hot air output device 8 and a controller 4 which are arranged outside the cavity and electrically connected;

[0061] The first air inlet 21 on the air inlet ratio regulating valve 2 is communicated with the external space outside the main structure of the overheated steam box, the second air inlet 22 on the air inlet ratio regulating valve 2 is communicated with the first air outlet 11 on the cavity through the outer cavity pipe 5, the second air outlet 23 on the air inlet ratio regulating valve 2 is communicated with the third air inlet 81 on the hot air output device 8, and the third air outlet 82 on the hot air output device 8 is communicated with the fourth air inlet 12 on the cavity 1 through the air inlet pipe 6;

[0062] The air inlet ratio regulating valve is used to adjust to a target opening based on a first control instruction sent by the controller, so as to control the ratio between the external air entering from the first air inlet and the internal air entering from the second air inlet at the same time, and to combine the external air and the internal air and transport them to the hot air output device;

[0063] The hot air output device is used to heat all the input gases based on the second control instruction sent by the controller, and then transport the hot air into the cavity through the air inlet duct to heat the cavity.

[0064] Specifically, the air inlet ratio regulating valve is used to simultaneously adjust the opening of the first air inlet and the second air inlet. For example, when the opening of the first air inlet is 60%, the opening of the second air inlet is 40%; when the opening of the first air inlet is 70%, the opening of the second air inlet is 30%. By controlling the opening of the two air inlets on the air inlet ratio regulating valve, the amount of gas entering from the two air inlets can be controlled, that is, the amount of external air entering from the first air inlet and the amount of internal air entering from the second air inlet. The temperature of the external air is comparable to the room temperature and is usually lower; while the internal gas comes from the cavity of the overheated steam box and is usually at a higher temperature. The air inlet ratio regulating valve combines the lower temperature external gas with the higher temperature internal gas and delivers them to the hot air output device.

[0065] The hot air output device is arranged outside the cavity of the over-temperature steam box. When the over-temperature steam box is working, all the gas delivered by the air inlet ratio regulating valve is heated and converted into hot air, and then delivered to the cavity through the air inlet duct to heat the inside of the cavity.

[0066] In this solution, the ratio between the input internal gas and the external gas is adjusted by the air inlet ratio regulating valve, and the inherent temperature of the gas from different sources can be utilized to adapt to the temperature control requirements of the over-temperature steamer in different modes, thereby saving energy and improving the efficiency of temperature control, thereby improving the overall performance of the over-temperature steamer.

[0067] In an practicable solution, the over-temperature steam box further includes a first temperature sensor disposed in the cavity and electrically connected to the controller;

[0068] The first temperature sensor is used to detect a first temperature in the cavity;

[0069] and / or,

[0070] The over-temperature steam box further includes a second temperature sensor 7 which is arranged on the air inlet duct 6 and is electrically connected to the controller 4;

[0071] The second temperature sensor is used to detect a second temperature in the air inlet duct.

[0072] Specifically, the first temperature sensor is used to detect the actual temperature inside the cavity, and the second temperature sensor is used to detect the actual temperature inside the air inlet duct.

[0073] In this solution, by setting the first temperature sensor and the second temperature sensor to detect the actual temperature in the cavity of the overheated steamer and the air inlet duct in real time, the temperature control mode can be adjusted in time according to the actual temperature, thereby achieving a dynamic balance of the temperature in the cavity and achieving a better heating effect.

[0074] In an practicable solution, the hot air output device 8 includes a blower 83 and a heater 84 which are electrically connected to the controller 4 respectively;

[0075] The air inlet of the blower is the third air inlet, the fourth air outlet on the blower is connected to the fifth air inlet on the heater, and the air outlet of the heater is the third air outlet;

[0076] The blower is used for sucking all the gas delivered by the air inlet ratio regulating valve based on the second control instruction sent by the controller, and delivering the gas to the heater through the fourth air outlet;

[0077] The heater is used to heat all the gases delivered by the blower, and deliver hot air into the cavity through the third air outlet via the air inlet duct.

[0078] Specifically, the blower is used to extract gas so that the gas enters the hot air output device; the heater is used to heat the gas so that the gas becomes hot air and then outputs it into the cavity.

[0079] In this solution, through the cooperation of the blower and the heater, all gases can be heated before being output, which is used for heating control of the over-temperature steamer and improves the heating effect of the over-temperature steamer.

[0080] In an implementable solution, the fourth air inlet is disposed on the side wall of the cavity and at a position less than a preset distance from the upper wall of the cavity.

[0081] Specifically, the fourth air inlet is arranged at a position close to the upper wall of the cavity, so that when hot air enters the cavity, condensed water on the upper wall of the cavity can be removed.

[0082] In this solution, by setting the hot air inlet of the cavity close to the upper wall of the cavity, the function of removing condensed water can be achieved, thereby improving the overall performance of the overheated steamer.

[0083] The overheated steamer provided in this embodiment adjusts the ratio between the input internal gas and the external gas through the air inlet ratio regulating valve, and can utilize the inherent temperature of the gases from different sources to adapt to the temperature control requirements in different modes of the overheated steamer, thereby saving energy and improving the efficiency of temperature control; at the same time, by transmitting hot air into the cavity through the hot air output device arranged outside the cavity, the liquefaction of water vapor can be reduced, the heating effect can be improved, and the overall performance of the overheated steamer can be improved.

[0084] Example 2

[0085] This embodiment provides a control method for an over-temperature steamer, which is used for the over-temperature steamer in Embodiment 1. Figure 5 As shown, the control method includes the following steps:

[0086] S1. Control the air inlet ratio regulating valve to adjust to the target opening, so as to control the ratio between the external air entering from the first air inlet and the internal air entering from the second air inlet at the same time, and transport the external air and the internal air together to the hot air output device;

[0087] S2. Control the hot air output device to heat all gases, and then deliver the hot air into the cavity through the air inlet duct to heat the cavity.

[0088] Specifically, by controlling the opening of the two air inlets on the air inlet ratio regulating valve, the amount of gas entering from the two air inlets can be controlled, that is, the amount of external air entering from the first air inlet and the amount of internal air entering from the second air inlet. The air inlet ratio regulating valve combines the lower temperature external air with the higher temperature internal air and delivers them to the hot air output device.

[0089] The hot air output device heats all the gases delivered by the air inlet ratio regulating valve, and delivers the hot air into the cavity through the air inlet duct to heat the inside of the cavity.

[0090] In this solution, the ratio between the input internal gas and the external gas is adjusted by the air inlet ratio control valve, and the inherent temperature of the gas from different sources can be utilized to adapt to the temperature control requirements of the overheated steamer in different modes, thereby saving energy and improving the efficiency of temperature control.

[0091] In one feasible solution, when the overheating steam box is in the preheating mode, Figure 6 As shown, step S1 includes:

[0092] S11. Control the opening of the first air inlet to be greater than the opening of the second air inlet.

[0093] Specifically, the actual temperature in the cavity during the preheating stage is relatively low and needs to be heated quickly. At this time, the amount of internal gas should be controlled to be greater than the amount of external gas.

[0094] To increase the heating speed, the first air inlet can be closed and only the second air inlet can be opened, that is, the opening of the first air inlet is controlled to 0% and the opening of the second air inlet is controlled to 100%, so that the gas in the cavity is continuously circulated and heated to quickly heat up.

[0095] In this solution, by controlling the opening of the air inlet ratio regulating valve and mainly inputting internal air, the preheating speed of the overheated steam box can be increased.

[0096] In an practicable solution, the over-temperature steam box further comprises a second temperature sensor disposed on the air inlet duct. When the over-temperature steam box is in the heat preservation mode, Figure 7 As shown, step S1 includes:

[0097] S12, controlling the second temperature sensor to obtain a second temperature in the air inlet duct;

[0098] S13, controlling the air inlet ratio regulating valve to adjust to a target opening according to the second temperature and the set temperature.

[0099] Specifically, the actual temperature in the air inlet duct, ie, the temperature of the hot air input into the cavity, is acquired by the second temperature sensor, and the opening of the air inlet ratio regulating valve is adjusted according to the relationship between the temperature of the hot air and the set temperature.

[0100] In this solution, according to the relationship between the temperature of the hot air in the air inlet duct and the set temperature, the amount of internal gas and external gas entering the air inlet ratio control valve is adjusted in real time, which can dynamically balance the temperature in the cavity to achieve better heating and insulation effects.

[0101] In one feasible solution, step S13 further includes:

[0102] If the second temperature is greater than the set temperature, the opening of the first air inlet is controlled to be greater than the opening of the second air inlet, wherein the opening of the first air inlet is positively correlated with the first temperature difference, and the first temperature difference is the difference between the second temperature and the set temperature;

[0103] and / or,

[0104] If the second temperature is lower than the set temperature, the opening of the first air inlet is controlled to be lower than the opening of the second air inlet, wherein the opening of the second air inlet is positively correlated with the second temperature difference, and the second temperature difference is the difference between the set temperature and the second temperature.

[0105] Specifically, if the temperature in the air inlet duct is higher than the set temperature of the overheated steam box, the temperature in the air inlet duct needs to be lowered. At this time, the opening of the first air inlet is controlled to be greater than the opening of the second air inlet, so that more low-temperature external air enters the circulation to lower the temperature in the air inlet duct. The greater the difference between the temperature in the air inlet duct and the set temperature, the greater the opening of the first air inlet is to achieve a faster cooling rate. Of course, it can also be supplemented by reducing the power of the heater in the hot air output device.

[0106] If the temperature in the air inlet duct is lower than the set temperature of the overheated steam box, the temperature in the air inlet duct needs to be increased. At this time, the opening of the first air inlet is controlled to be smaller than the opening of the second air inlet, so that more internal gas with a higher temperature enters the circulation to increase the temperature in the air inlet duct. The greater the difference between the set temperature and the temperature in the air inlet duct, the greater the opening of the second air inlet is to achieve a faster temperature increase. Of course, this can also be supplemented by increasing the power of the heater in the hot air output device.

[0107] If the temperature in the air inlet duct is equal to the set temperature of the over-temperature steam box, the current working state remains unchanged.

[0108] In this solution, the amount of internal gas and external gas entering the air inlet ratio regulating valve is adjusted in real time according to the relationship between the temperature of the hot air in the air inlet duct and the set temperature as well as the temperature difference, which can dynamically and quickly balance the temperature in the cavity to achieve better heating and insulation effects.

[0109] In one feasible solution, the hot air output device includes a heater;

[0110] When the second temperature is greater than the set temperature, the control method further includes: reducing the heating power of the heater to the first set power;

[0111] and / or,

[0112] When the second temperature is lower than the set temperature, the control method further includes: increasing the heating power of the heater to a second set power.

[0113] Specifically, if the temperature in the air inlet duct is higher than the set temperature of the overheated steam box, the temperature in the air inlet duct needs to be lowered. In addition to changing the opening of the air inlet ratio regulating valve, the power of the heater in the hot air output device can also be reduced.

[0114] If the temperature in the air inlet duct is lower than the set temperature of the overheated steam box, the temperature in the air inlet duct needs to be increased. In addition to changing the opening of the air inlet ratio regulating valve, the power of the heater in the hot air output device can also be increased.

[0115] In this solution, the efficiency of temperature control can be further improved by adjusting the power of the heater in the hot air output device.

[0116] In one feasible solution, when the over-temperature steam box is in the cooling mode, Figure 8 As shown, step S1 includes:

[0117] S14, controlling the opening of the first air inlet to be smaller than the opening of the second air inlet.

[0118] Specifically, the overheated steamer needs to be cooled down near the end of its operation or after the end of its operation. During the cooling stage, the amount of external gas needs to be controlled to be greater than the amount of internal gas.

[0119] To increase the cooling speed, only the first air inlet can be opened and the second air inlet can be closed, that is, the opening of the first air inlet is controlled to 100% and the opening of the second air inlet is controlled to 0%, so that a large amount of lower temperature external air enters the circulation to quickly reduce the temperature in the cavity.

[0120] In this solution, by controlling the opening of the air inlet ratio regulating valve and mainly inputting external air, the cooling speed of the overheated steam box can be increased.

[0121] In one feasible solution, the hot air output device includes a heater;

[0122] The control method also includes:

[0123] Detect the open / close status of the door of the over-temperature steam box;

[0124] If the door is closed, the heater is controlled to be turned off;

[0125] If the door is in an open state, the heater is controlled to operate at a third set power.

[0126] Specifically, if the door of the overheated steamer is closed and it is still in the cooling stage near the end of work, it is necessary to cool down quickly to avoid the instantaneous temperature being too high when the door is opened. Therefore, at this time, the heater should be controlled to be turned off and rapid cooling should be achieved by the entry of a large amount of external air.

[0127] If the door of the over-temperature steamer is open, the work is finished. At this time, in order to facilitate the user to clean, the heater can be turned on to a lower power for heating, so as to help the user to remove the water vapor in the cavity in time to achieve the effect of dehumidification and deodorization.

[0128] In this solution, the working mode of the heater is adjusted according to different requirements of the cooling stage of the overheated steamer, which can further improve the rationality and flexibility of the control method of the overheated steamer to adapt to different application scenarios and enhance the user experience.

[0129] In an implementable solution, a steam generating device is further provided in the overtemperature steam box, a first temperature sensor is provided in the cavity, and the control method further includes:

[0130] Controlling the first temperature sensor to obtain a first temperature in the cavity;

[0131] According to the first temperature and the set temperature, the working states of the hot air output device and the steam generating device are controlled to heat the interior of the cavity.

[0132] Specifically, the set temperature can be a temperature set by the user according to specific cooking requirements. According to the actual temperature in the cavity and the set temperature, the switch state and operating power of the hot air output device and the steam generating device are controlled to heat the cavity.

[0133] In this solution, by obtaining the actual temperature in the cavity, the steam generating device and the hot air output device work together to dynamically balance the temperature in the cavity and improve the heating control effect of the over-temperature steamer.

[0134] The complete control process of the control method of the over-temperature steamer provided in this embodiment is described below with a specific implementation method:

[0135] 1. Warm-up stage

[0136] After the over-temperature steamer is started, the water is not heated first, but the air in the cavity is quickly heated to make the top of the cavity have a certain temperature, so as not to quickly generate condensed water, and also to allow the cavity to quickly reach a thermal equilibrium, reducing the heating time. After the temperature sensor in the cavity detects that the cavity temperature has reached X degrees (the set temperature is different for different modes, for example, ordinary steaming is higher than over-temperature steaming, and this X cannot be too high, otherwise the food in the cavity will become dry or deformed), the steam generating device is turned on to generate steam.

[0137] 2. Insulation stage:

[0138] 1. Ordinary steam: The working time and working power of the heater are controlled by PWM (pulse width modulation) of the thyristor. The main purpose is to remove the condensed water on the top of the cavity and maintain the temperature in the cavity. The humidity level in the cavity is controlled by controlling the ratio of the heater and the steam generator. N levels will be set, and each level will set a different average power for the heater and steam generator to drive. For example: the heater has 1 to N gears, and the steam generator also has 1 to N gears. If the humidity gear is required to be 1 at this time, set the heater to N gear and the steam generator to 1 gear. Humidity control is achieved in this combination, and the dual-input proportional control valve (that is, the above-mentioned air inlet proportional control valve) is used for heating control.

[0139] 2. Over-temperature steaming: The switch, working power and working time of the heater will be adjusted according to the set over-temperature steaming temperature (i.e. the set temperature mentioned above) and the temperature in the cavity. When the preheating temperature reaches Z degrees, the steam generator can be turned on to allow it to gradually generate steam and shorten the heating time; after the cavity temperature reaches the set temperature, it can be controlled according to the humidity level. If the humidity level is set to 3 levels, the steam generator is controlled according to 3 corresponding powers. The control of the heater is based on the temperature sensor on the air inlet duct and the temperature sensor in the cavity. When the detected temperature of the cavity is higher than the set temperature, the outlet temperature of the heater is controlled within the set temperature - M degrees to achieve dynamic balance; when the detected temperature of the cavity is lower than the set temperature, the outlet temperature of the heater is controlled within the set temperature + N degrees to achieve dynamic balance, and cooperate with the dual-input proportional control valve for heating control.

[0140] 3. Double input proportional control valve control:

[0141] 1. Preheating stage: that is, when the temperature has not reached Z, the dual-input proportional control valve is mainly based on the steam air inlet, and the external air inlet is closed, so that the gas in the cavity is continuously circulated and heated to quickly reach the set temperature. That is, the proportion of the steam air inlet is defined as 100%, and the proportion of the external air inlet is defined as 0%.

[0142] 2. Insulation stage: When the temperature in the air inlet duct is higher than the set temperature X degrees, quickly adjust the control valve to introduce more low-temperature external air. Specifically, the proportion of steam air inlet is (5-X) / 5, and the proportion of external air inlet is X / 5; when X≥5, the proportion of steam air inlet is 0%, and the proportion of external air inlet is 100%. In addition, the power of the heater is gradually reduced at this time, because the heater has thermal inertia, and it is necessary to introduce external low temperature to accelerate the cooling;

[0143] When the temperature is too low, the temperature in the air inlet duct is lower than the set temperature Y degrees, the control valve is adjusted to introduce more high-temperature gas into the cavity. Specifically, the proportion of the steam inlet is Y / 5, and the proportion of the external air inlet is (5-Y) / 5; when Y≥5, the proportion of the steam inlet is 100%, and the proportion of the external air inlet is 0%.

[0144] 3.
