Furthermore, detailed descriptions of known technologies that are unnecessary for the features of this application are omitted.

[0034] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the term “comprising” as used in the specification of this application means the presence of the stated 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” as used herein includes all or any units and all combinations thereof of one or more associatedly listed items.

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

[0036] In this embodiment, a smoke collection chamber is formed inside the cabinet 1, and a fan is installed inside the smoke collection chamber. A smoke inlet for the smoke collection chamber is located at the top of the cabinet 1, and a smoke outlet for the smoke collection chamber is located at the bottom or bottom of the cabinet 1; the steam oven 2 is installed below the cabinet 1. The inner liner 21 has a cavity for accommodating food. The fan can be connected to the inner liner 21 via a pipe. During the cooking stage, the inner liner 21 contains a large amount of heat and pressure. The fan expels the gas and heat from the inner liner 21, reducing the pressure inside the inner liner 21 while simultaneously creating airflow within the inner liner 21. This facilitates the redistribution of heat within the inner liner 21, reduces temperature differences, and achieves uniform temperature distribution.

[0037] One of the first normally open heating element 24 and the second normally open heating element 25 is located at the top of the inner cavity 21, and the other is located at the bottom of the inner cavity 21. After the steam oven 2 is started, both the first normally open heating element 24 and the second normally open heating element 25 operate continuously at a preset power until the steam oven 2 is turned off. The first normally open heating element 24 and the second normally open heating element 25 continuously provide heat for cooking food in the vertical direction. Both the first normally open heating element 24 and the second normally open heating element 25 are heating tubes, which can be bent into different structures. The specific structure is not specifically limited in this application.

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

[0039] As an optional implementation, the heat-generating component 23 is annular; the fan 26, the heat-generating component 23 and the air outlet 28 are arranged sequentially in the horizontal direction, and the airflow generated by the fan 26 flows sequentially through the heat-generating component 23 and the air outlet 28 to flow into the heating area.

[0040] Based on the aforementioned embodiments, in this embodiment, the heat-replenishing component 23 is disposed on the air outlet side of the fan 26. The airflow generated by the fan 26 flows into the ring from one side of the heat-replenishing component 23 and flows out from the other side. An air outlet mesh 28 is provided on the air outlet side of the heat-replenishing component 23. When the heat-replenishing component 23 is operating, the airflow generated by the fan 26 carries away the heat generated by the heat-replenishing component 23 to replenish the heat inside the inner liner 21. Optionally, both the heat-replenishing component 23 and the fan 26 are disposed on the left side of the inner liner 21, and the airflow generated by the fan 26 blows from the left side of the inner liner 21 to the right side. Both the heat-replenishing component 23 and the fan 26 operate under preset conditions and are not components that are in a normally open state.

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

[0042] Based on the aforementioned embodiments, in this embodiment, the convection fan 22 is positioned high behind the steam oven 2. The convection fan 22 has two ends, one end serving as an air inlet and the other end as an air outlet. For example, when the convection fan 22 rotates in the forward direction, the first end serves as the air inlet and the second end as the air outlet; when the convection fan 22 rotates in the reverse direction, the first end serves as the air outlet and the second end serves as the air inlet. The rotation of the convection fan 22 in different directions corresponds to forming a clockwise or counterclockwise air circulation direction.

[0043] The convection fan 22 has ventilation ducts connected to both ends. One ventilation duct connects to the left side of the inner liner 21, and the other connects to the right side of the inner liner 21. Under the action of the convection fan 22, the gas inside the inner liner 21 flows out from the left or right side, flows through the ventilation duct and the convection fan 22, and flows back into the inner liner 21 from the other side, forming a circulating airflow. By using the fan 26 and the convection fan 22, or only the convection fan 22, to create lateral airflows of different speeds, the heat distribution of the steam oven 2 can be adjusted.

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

[0045] The integrated stove provided in this application embodiment confirms the existence of a temperature difference by obtaining temperature data from multiple temperature sensors 27. If a temperature difference exists, the heating element 23, fan 26 and / or convection fan 22 are controlled according to different temperature difference conditions to reduce the temperature difference inside the inner pot 21, so that the temperature inside the inner pot 21 can quickly reach a uniform distribution state, thereby achieving temperature difference control and improving the cooking effect of food.

[0046] like Figure 9 As shown, based on the same inventive concept, this application provides a control method for the integrated stove described in the foregoing embodiments, which mainly includes steps S1-S3:

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

[0048] Step S2: Determine the current control command corresponding to the acquired current temperature difference data based on the preset correspondence between temperature difference data and control command and the acquired current temperature difference data;

[0049] Step S3: Output the current control command that has been determined.

[0050] Based on the aforementioned 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 liner 21. Therefore, the current temperature difference data obtained in step S1 is the temperature difference between the left and right relative regions of the inner liner 21. This 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 can be positive, negative, or 0. If the difference is positive, it means that the temperature of the left side of the inner liner 21 is higher than the temperature of the right side of the inner liner 21. Conversely, if the difference is negative, it means that the temperature of the left side of the inner liner 21 is lower than the temperature of the right side of the inner liner 21. If the difference is 0, it means that the temperature of the left side of the inner liner 21 is equal to the temperature of the right side of the inner liner 21.

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

[0052] In step S3, the determined current control command is output to the component associated with the current control command to execute the corresponding action.

[0053] The integrated stove control method provided in this application embodiment detects the temperature of the left and right sides of the inner tank 21 by using a first temperature sensor and a second temperature sensor, respectively. If there is a temperature difference, the heating element 23, fan 26 and / or convection fan 22 are controlled according to the different temperature difference conditions to make the temperature inside the inner tank 21 quickly reach uniformity, so as to achieve stable and uniform temperature control and thus improve the cooking effect of food.

[0054] As an optional implementation, step S2 above determines the current control command corresponding to the acquired current temperature difference data based on the preset correspondence between temperature difference data and control commands and the acquired current temperature difference data. This mainly includes the following steps:

[0055] The current temperature difference level is determined based on the preset correspondence between temperature difference data and temperature difference level, and the current target temperature difference data obtained.

[0056] The current control command corresponding to the current temperature difference level is determined based on the preset correspondence between the temperature difference level and the control command, and the determined current temperature difference level.

[0057] Based on the foregoing embodiments, in this embodiment, to facilitate temperature difference regulation, the technical solution of this application first determines the current temperature difference level corresponding to the current temperature difference data. This current temperature difference level can be divided into a large temperature difference level, a medium temperature difference level, and a small temperature difference level. Regardless of the temperature difference level, it involves situations where the temperature in the left region is higher than the temperature in the right region or vice versa. Therefore, it is necessary to determine corresponding control commands for different temperature difference situations and different degrees of temperature difference.

[0058] As an optional implementation, if the current temperature difference level is the first level, the determined current control command includes the fan being in the second exhaust state, the heat exchanger 23 being in the off state, the fan 26 being in the second blowing state, and the convection fan 22 being in the second circulating air exchange state in the first direction.

[0059] Based on the aforementioned embodiments, in this embodiment, the first level is when the temperature of the left side region of the inner liner 21 is higher than that of the right side region, and there is a large temperature difference. In order to reduce the temperature difference, the fan is set to the second exhaust mode to form an airflow that exhausts gas and heat out of the inner liner 21; the airflow generated by the fan 26 in the second blowing mode flows from left to right in the inner liner 21; the convection fan 22 is in the second circulation mode of the first direction, 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 in from the left side of the inner liner 21 to achieve heat redistribution, reduce the temperature difference, and achieve uniform temperature.

[0060] In one specific embodiment, a first temperature sensor detects a first temperature, and a 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 element 23 is controlled to be in a closed state; the fan runs at twice the preset speed; the convection fan 22 rotates in the opposite direction at twice the preset speed, so that the airflow generated by the convection fan 22 enters from the left side of the inner liner 21 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. Different rotation directions can achieve corresponding air circulation directions, namely counterclockwise or clockwise. The first direction is either forward or reverse.

[0062] As an optional implementation, if the current temperature difference level is the second level, the determined current control command includes the fan being in the second exhaust state, the heat exchanger 23 being in the off state, the fan 26 being in the first blowing state, and the convection fan 22 being in the first direction first level circulation state; the intensity of the second blowing state of the fan 26 is greater than the intensity of the first blowing state; the intensity of the second circulation state of the convection fan 22 is greater than the intensity of the first circulation state.

[0063] Based on the aforementioned embodiments, in this embodiment, the second level is characterized by a temperature difference where the left side of the inner liner 21 is higher than the right side. To reduce this temperature difference, the fan is set to its second exhaust setting to create an airflow that exhausts gas and heat within the inner liner 21; the fan 26, in its first blowing setting, generates airflow that flows from left to right within the inner liner 21; and the convection fan 22, in its first-direction, first-level circulating air exchange setting, causes gas within the inner liner 21 to flow out from the right side, pass through the convection fan 22, and then flow back in from the left side, thus redistributing heat, reducing the temperature difference, and achieving uniform temperature.

[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 the off state; the fan runs at a preset speed; and the convection fan 22 rotates in the opposite direction at a preset speed.

[0065] As an optional implementation, if the current temperature difference level is level three, the determined current control command includes the fan being in the second exhaust state, the heat exchanger 23 being in the on state, the fan 26 being in the second blowing state, and the convection fan 22 being in the second direction second-level circulating air exchange state; the first direction and the second direction are opposite.

[0066] Based on the aforementioned embodiments, in this embodiment, the third level is a situation where the temperature on the left side of the inner liner 21 is lower than the temperature on the right side, and there is a significant temperature difference. To reduce the temperature difference, the fan is set to the second exhaust mode to create an airflow that exhausts gas and heat within the inner liner 21; the fan 26 is set to the second blowing mode to generate airflow that flows from left to right within the inner liner 21; the convection fan 22 is set to the second direction and second level of circulation mode, where gas flows out from the left side of the inner liner 21, passes through the convection fan 22, and then flows in from the right side of the inner liner 21, thus redistributing heat, reducing the temperature difference, and achieving 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 degrees Celsius, the heating element 23 is controlled to be in the open state; the fan runs at twice the preset speed; the convection fan 22 rotates forward at twice 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 positive and the second direction is negative.

[0069] Optionally, the first direction is the opposite direction, and the second direction is the positive direction.

[0070] As an optional implementation, if the current temperature difference level is level four, the determined current control command includes the fan being in the second exhaust state, the heat exchanger 23 being in the on state, the fan 26 being in the first blowing state, and the convection fan 22 being in the second direction first level circulating air exchange state.

[0071] Based on the aforementioned embodiments, in this embodiment, the fourth level is characterized by a temperature difference where the temperature on the left side of the inner liner 21 is lower than that on the right side. To reduce this temperature difference, the fan is set to the second exhaust mode to create an airflow that exhausts gas and heat from the inner liner 21; the fan 26 is set to the first blowing mode to generate airflow that flows from left to right within the inner liner 21; and the convection fan 22 is set to the first circulating mode in the second direction, causing gas to flow out from the left side of the inner liner 21, pass through the convection fan 22, and then flow in from the right side of the inner liner 21. This redistributes heat, reduces the temperature difference, and achieves uniform temperature.

[0072] Based on the foregoing embodiments, in a specific embodiment, if the difference between the first temperature and the second temperature is greater than -15 degrees Celsius and less than or equal to -5 degrees Celsius, the heating element 23 is controlled to be in the open state; the fan runs at a preset speed; the convection fan 22 rotates forward at a 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.

[0073] As an optional implementation, if the current temperature difference level is level 5, the current control command is determined to include the fan being in the first exhaust state, the heat exchanger 23 being in the off state, the fan 26 being in the off state, and the convection fan 22 being in the alternating circulation state of the first direction and the second direction.

[0074] Based on the aforementioned embodiments, in this embodiment, the fifth level is a situation where, regardless of whether the temperature of the left or right side of the inner liner 21 is higher, there is a low temperature difference. At this temperature difference level, the convection fan 22 only needs to rotate alternately in the forward and reverse directions at preset time intervals to achieve alternating clockwise and counterclockwise air circulation.

[0075] Based on the foregoing embodiments, in a specific embodiment, if the difference between the first temperature and the second temperature is greater than -5 degrees Celsius and less than or equal to 0, or greater than 0 and less than or equal to 5, then the heating element 23 is controlled to be in a closed state; the fan is in a closed state; the convection fan 22 rotates alternately in the forward and reverse directions at 0.5 times the preset speed, with the alternation interval being a preset duration.

[0076] As an optional implementation, before performing the step of acquiring the current temperature difference data of the multiple temperature sensors 27, the method further includes:

[0077] Acquire the current temperature data detected by all temperature sensors 27;

[0078] If the current temperature data detected by any temperature sensor 27 meets the preset temperature control start conditions, then the step of acquiring the current temperature difference data of multiple temperature sensors 27 is executed.

[0079] Based on the aforementioned embodiments, in this embodiment, the steam oven 2 needs to be preheated before operation. The preheating temperature is lower than the set cooking temperature. Therefore, when at least one of the first temperature and the second temperature reaches the preheating temperature, the step of acquiring the current temperature difference data of multiple temperature sensors 27 is executed.

[0080] In some embodiments, the control method for the integrated stove further includes:

[0081] If the current temperature difference level is the same as the previously determined temperature difference level, then the step of obtaining the current temperature difference data of both the first temperature sensor and the second temperature sensor is executed.

[0082] Based on the aforementioned embodiments, in this embodiment, if the current temperature difference level is the same as the previously determined temperature difference level, it indicates that the temperature difference has not changed and further detection is required.

[0083] Based on the same inventive concept, this application provides a control device for the integrated stove described in the foregoing embodiments, which executes the control method of any one of the foregoing embodiments.

[0084] The integrated stove control device provided in this application embodiment confirms the existence of a temperature difference by obtaining temperature data from multiple temperature sensors. If a temperature difference exists, the heating element 23, fan 26 and / or convection fan 22 are controlled according to different temperature difference conditions to reduce the temperature difference inside the inner pot 21, so that the temperature inside the inner pot 21 can quickly reach a uniform distribution, thereby achieving temperature difference control and improving the cooking effect of food.
