[0034] Those skilled in the art will appreciate that, unless otherwise stated, the singular forms "a", "an", "said" and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present application refers to the presence of the features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof. The term "and / or" used herein includes all or any unit and all combinations of one or more associated listed items.

[0035] like Figure 1-8As shown, the embodiment of the present application provides an integrated stove, which mainly includes a cabinet 1, a fan and a steam oven 2. The cabinet 1 has a smoke collecting chamber inside; the steam oven 2 is assembled in the cabinet 1, and the steam oven 2 includes an inner tank 21, a convection fan 22, and a supplementary heating element 23, a first normally open heating element 24, a second normally open heating element 25, a fan 26, a plurality of temperature sensors 27 and an air outlet net 28 arranged in the inner tank 21; the fan is assembled in the smoke collecting chamber, and the fan is arranged on one side of the steam oven 2, and is used to reduce the pressure in the inner tank 21 by exhausting air; wherein the first normally open heating element 24 and the second normally open heating element 25 are arranged away from each other in the longitudinal direction to form a heating area between the first normally open heating element 24 and the second normally open heating element 25; the supplementary heating element 23, the fan 26 and the air outlet net 28 are arranged on the same side so that the airflow generated by the fan 26 flows horizontally and flows through the heating area; the two ends of the convection fan 22 are respectively connected to the inner tank 21 through pipes to form a circulating air path.

[0036] In this embodiment, a smoke collecting chamber is formed in the cabinet 1, and a fan is installed in the smoke collecting chamber. A smoke inlet of the smoke collecting chamber is arranged above the cabinet 1, and a smoke outlet of the smoke collecting chamber is arranged below or at the bottom of the cabinet 1; the steam oven 2 is installed below the cabinet 1. The inner pot 21 has a accommodating cavity for accommodating food. The fan can be connected to the inner pot 21 through a pipeline. During the cooking stage, there is a large amount of heat in the inner pot 21, and there is a large pressure in the inner pot 21. The fan discharges the gas and heat in the inner pot 21, reduces the pressure in the inner pot 21, and forms an airflow in the inner pot 21, so as to redistribute the heat of the inner pot 21, reduce the temperature difference, and achieve uniform temperature distribution.

[0037] One of the first normally-on heating element 24 and the second normally-on heating element 25 is disposed at the top of the inner pot 21, and the other is disposed at the bottom of the inner pot 21; after the steam oven 2 is started, the first normally-on heating element 24 and the second normally-on heating element 25 continue to operate at a preset power until the steam oven 2 is turned off. The first normally-on heating element 24 and the second normally-on heating element 25 continuously provide heat for cooking ingredients in the longitudinal direction. The first normally-on heating element 24 and the second normally-on heating element 25 are both heating tubes, which can be bent to form different structures, and the specific structure is not specifically limited in this application.

[0038] The multiple temperature sensors 27 are used to detect temperature data at different locations in the inner liner 21, and the temperature data is used to determine whether there is a temperature difference in the inner liner 21. In some embodiments, a temperature sensor 27 is disposed on the left and right sides of the inner liner 21, that is, two temperature sensors 27, and the two temperature sensors 27 are a first temperature sensor and a second temperature sensor.

[0039] As an optional embodiment, the heating element 23 is annular; the fan 26, the heating element 23 and the air outlet net 28 are arranged in sequence along the horizontal direction, and the air flow generated by the fan 26 flows through the heating element 23 and the air outlet net 28 in sequence to flow into the heating area.

[0040] Based on the above embodiments, in this embodiment, the heating element 23 is arranged on the air outlet side of the fan 26, and the airflow generated by the fan 26 flows into the ring from one side of the heating element 23 and flows out from the other side. The air outlet side of the heating element 23 is provided with an air outlet net 28. When the heating element 23 is in operation, the airflow generated by the fan 26 takes away the heat generated by the heating element 23 to supplement the heat in the inner liner 21. Optionally, the heating element 23 and the fan 26 are both arranged on the left side of the inner liner 21, and the airflow generated by the fan 26 blows from the left area of ​​the inner liner 21 to the right area. Both the heating element 23 and the fan 26 operate under preset working conditions and are not components in a normally open state.

[0041] As an optional implementation, the two ends of the convection fan 22 connected to the inner liner 21 are arranged on opposite sides of the inner liner 21 .

[0042] Based on the above embodiments, in this embodiment, the convection fan 22 is arranged at a high position on the rear side of the steam oven 2, and the convection fan 22 has two ends, one end is used as an air inlet, and the other end is used as an air outlet; for example, when the convection fan 22 rotates in the forward direction, the first end is used as an air inlet, and the second end is used as an air outlet; when the convection fan 22 rotates in the reverse direction, the first end is used as an air outlet, and the second end is used as an air inlet. The convection fan 22 rotates in different directions to form a corresponding clockwise or counterclockwise circulation ventilation direction.

[0043] The two ends of the convection fan 22 are connected to ventilation ducts, one ventilation duct is connected to the left side of the inner container 21, and the other ventilation duct is connected to the right side of the inner container 21; under the action of the convection fan 22, the gas in the inner container 21 flows out of the inner container 21 from the left or right side, flows through the ventilation duct and the convection fan 22, and flows into the inner container 21 from the other side to form a circulating air path. The fan 26 and the convection fan 22, or only the convection fan 22, form transverse airflows of different flow rates to adjust the heat distribution of the steam oven 2.

[0044] In some embodiments, the integrated stove further comprises a controller, which is connected to and controls the fan, the supplementary heating element 23, the first normally open heating element 24, the second normally open heating element 25, the fan 26, the convection fan 22 and a plurality of temperature sensors 27. The specific control logic of the controller is detailed in the following embodiments.

[0045] The integrated stove provided in the embodiment of the present application confirms whether there is a temperature difference through temperature data obtained by multiple temperature sensors 27; if there is a temperature difference, the heating component 23, the fan 26 and / or the convection fan 22 are controlled according to different temperature difference conditions to reduce the temperature difference in the inner pot 21, so that the temperature inside the inner pot 21 quickly reaches a uniform distribution state, thereby realizing temperature difference control and improving the cooking effect of the ingredients.

[0046] like Fig. 9 As shown, based on the same inventive concept, the embodiment of the present application provides a control method of the integrated stove of the aforementioned embodiment, which mainly includes steps S1-S3:

[0047] Step S1: obtaining current temperature difference data of multiple temperature sensors 27;

[0048] Step S2: determining a current control instruction corresponding to the acquired current temperature difference data according to the preset correspondence between the temperature difference data and the control instruction and the acquired current temperature difference data;

[0049] Step S3: Output the determined current control instruction.

[0050] Based on the foregoing embodiments, in this embodiment, the multiple temperature sensors 27 only include a first temperature sensor and a second temperature sensor arranged on the left and right sides of the inner tank 21. Then the current temperature difference data obtained in step S1 is the temperature difference between the left and right relatively opposite areas of the inner tank 21. The temperature difference can be determined by the difference between the first temperature value obtained by the first temperature sensor and the second temperature value obtained by the second temperature sensor. The difference is positive, negative or 0; if the difference is positive, it means that the temperature of the left area of ​​the inner tank 21 is higher than the temperature of the right area of ​​the inner tank 21; on the contrary, if the difference is negative, it means that the temperature of the left area of ​​the inner tank 21 is lower than the temperature of the right area of ​​the inner tank 21; if the difference is 0, it means that the temperature of the left area of ​​the inner tank 21 is equal to the temperature of the right area of ​​the inner tank 21.

[0051] The current control instruction obtained in step S2 is a control instruction for the aforementioned three situations to quickly achieve a uniform temperature inside the inner tank 21. The current control instruction corresponding to the current temperature difference data determined includes at least one of the control information of the fan, the control information of the heating element 23, the control information of the fan 26 and the control information of the convection fan 22.

[0052] Outputting the determined current control instruction in step S3 is to transmit the current control instruction to the component associated with the current control instruction to execute the corresponding action.

[0053] The control method of the integrated stove provided in the embodiment of the present application detects the temperature of the left area and the temperature of the right area of ​​the inner pot 21 respectively through the first temperature sensor and the second temperature sensor; if there is a temperature difference, the heating component 23, the fan 26 and / or the convection fan 22 are controlled according to different temperature difference conditions to make the temperature inside the inner pot 21 quickly reach uniformity, so as to achieve stable and uniform temperature control, thereby improving the cooking effect of the ingredients.

[0054] As an optional implementation, the above step S2 determines the current control instruction corresponding to the acquired current temperature difference data according to the correspondence between the preset temperature difference data and the control instruction and the acquired current temperature difference data, mainly including the steps of:

[0055] Determine the current temperature difference level corresponding to the current temperature difference data according to the corresponding relationship between the preset temperature difference data and the temperature difference level and the acquired current target temperature difference data;

[0056] The current control instruction corresponding to the current temperature difference level is determined according to the corresponding relationship between the preset temperature difference level and the control instruction and the determined current temperature difference level.

[0057] Based on the above embodiments, in this embodiment, in order to facilitate temperature difference adjustment, the technical solution of this application is to first determine the current temperature difference level corresponding to the current temperature difference data, and the current temperature difference level can be divided into a larger temperature difference level, a medium temperature difference level and a smaller temperature difference level. Regardless of the temperature difference level, it involves the situation where the temperature of the left area is higher than the temperature of the right area or the temperature of the right area is higher than the temperature of the left area. Therefore, it is necessary to determine the corresponding control instructions for different temperature difference situations and different temperature difference degrees.

[0058] As an optional implementation, if the current temperature difference level belongs to the first level, the current control instructions determined include the fan being in the second gear exhaust state, the heat supply component 23 being in the closed state, the fan 26 being in the second gear blowing state and the convection fan 22 being in the first direction second gear circulation air exchange state.

In order to reduce the temperature difference, the fan is in the second gear exhaust state to form an airflow for discharging gas and heat in the inner liner 21; the airflow generated by the fan 26 in the second gear blowing state flows from left to right in the inner liner 21; the convection fan 22 is in the first direction second gear circulation and air exchange state stage, and the gas in the inner liner 21 flows out from the right side of the inner liner 21, flows through the convection fan 22, and then flows into the left side of the inner liner 21, so as to realize heat redistribution, reduce temperature difference, and achieve temperature uniformity.

[0060] In a specific embodiment, the first temperature sensor detects a first temperature, and the second temperature sensor detects a second temperature; if the difference between the first temperature and the second temperature is greater than 15 and less than or equal to 30, the heating component 23 is controlled to be in a closed state; the fan runs at 2 times the preset speed; the convection fan 22 rotates in the opposite direction at 2 times the preset speed, so that the airflow generated by the convection fan 22 enters the inner liner 21 from the left side and flows out from the right side of the inner liner 21.

[0061] It should be noted that the convection fan 22 has two different rotation directions, namely, forward and reverse, and different rotation directions can achieve corresponding circulation ventilation directions, namely, counterclockwise or clockwise. The first direction is forward or reverse.

[0064] Based on the foregoing embodiments, in a specific embodiment, if the difference between the first temperature and the second temperature is greater than 5 and less than or equal to 15, the heating element 23 is controlled to be in a closed state; the fan runs at a preset speed; and the convection fan 22 rotates in the reverse direction at a preset speed.

[0066] Based on the above embodiments, in this embodiment, the third level is when the temperature of the left area of ​​the inner liner 21 is lower than that of the right area, and there is a high temperature difference. In order to reduce the temperature difference, the fan is in the second gear exhaust state to form an airflow for discharging gas and heat in the inner liner 21; the airflow generated by the fan 26 in the second gear blowing state flows from left to right in the inner liner 21; the convection fan 22 is in the second direction second gear circulation and air exchange state stage, and the gas in the inner liner 21 flows out from the left side of the inner liner 21, flows through the convection fan 22, and then flows into the right side of the inner liner 21, so as to redistribute the heat, reduce the temperature difference, and achieve uniform temperature.

[0067] Based on the foregoing embodiments, in a specific embodiment, if the difference between the first temperature and the second temperature is greater than -30 degrees Celsius and less than or equal to -15, the heating component 23 is controlled to be in an open state; the fan runs at 2 times the preset speed; the convection fan 22 rotates forward at 2 times the preset speed, so that the airflow generated by the convection fan 22 enters from the right side of the inner liner 21 and flows out from the left side of the inner liner 21.

[0068] Optionally, the first direction is forward and the second direction is reverse.

[0069] Optionally, the first direction is reverse and the second direction is forward.

[0071] Based on the above embodiments, in this embodiment, the fourth level is when the temperature of the left area of ​​the inner liner 21 is lower than that of the right area, and there is a medium temperature difference. In order to reduce the temperature difference, the fan is in the second gear exhaust state to form an airflow for discharging gas and heat in the inner liner 21; the airflow generated by the fan 26 in the first gear blowing state flows from left to right in the inner liner 21; the convection fan 22 is in the second direction first gear circulation and ventilation state stage, and the gas in the inner liner 21 flows out from the left side of the inner liner 21, flows through the convection fan 22, and then flows into the right side of the inner liner 21, so as to realize heat redistribution, reduce temperature difference, and achieve temperature uniformity.
