[0044] Figure 1 A flowchart of a method for controlling a cooking appliance provided by an embodiment of the present invention is shown in FIG. Figure 2 A schematic diagram of the structure of a cooking appliance provided by an embodiment of the present invention. Figure 3 A schematic diagram of the structure of another cooking appliance provided by an embodiment of the present invention is shown in FIG. Figure 1-Figure 3 As shown, this embodiment is applicable to the situation where the user opens the door of the cooking appliance. The method can be executed by the control device of the cooking appliance. The control device can be implemented in the form of hardware and / or software, and the control device can be configured in the controller of the cooking appliance.

[0045] The cooking utensil may be any cooking utensil with a cooking box, such as an integrated stove, a steam oven, a steam box or an oven. The following embodiments are only described using the cooking utensil as an integrated stove as an example, but are not limited to this.

[0046] Specifically, Figure 2 and Figure 3 As shown, the cooking appliance includes a cooking box 10, a cooking cavity 11, a box door 12, a door control detection module 13, an air intake pipe 14, an exhaust pipe 15, a first solenoid valve 16, a second solenoid valve 17, an air intake pump 18 and an exhaust pump 19. The door control detection module 13 is used to detect the opening degree of the box door 12. The first solenoid valve 16 is arranged on the air intake pipe 14, and the second solenoid valve 17 is arranged on the exhaust pipe 15. The air intake pump 18 is used to draw the gas outside the cooking cavity 11 into the cooking cavity 11 through the air intake pipe 14, and the exhaust pump 15 is used to discharge the gas inside the cooking cavity 11 out of the cooking cavity 11 through the exhaust pipe 15.

[0047] The cooking box 10 may be a steam oven, a steam box or an oven box of an integrated stove.

[0048] The cooking cavity 11 in the cooking box 10 is used to hold food so as to heat the food.

[0049] The cabinet door 12 is used to close or open the cooking cavity 11 .

[0050] The air inlet pipe 14 is used to introduce the gas outside the cooking cavity 11 into the cooking cavity 11 , and the exhaust pipe 15 is used to discharge the gas in the cooking cavity 11 to the outside of the cooking cavity 11 .

[0051] The first solenoid valve 16 is used to control the opening and closing of the passage of the intake pipe 14 , and the second solenoid valve 17 is used to control the opening and closing of the passage of the exhaust pipe 15 .

[0052] Continue to refer Figure 1 As shown, the control method includes:

[0053] S110, obtaining the opening degree of the box door through the door control detection module.

[0054] S120, obtaining target opening degrees of the first solenoid valve and the second solenoid valve, and target powers of the intake pump and the exhaust pump according to the opening degree of the chamber door.

[0055] S130, controlling the first solenoid valve and the second solenoid valve to open at a target opening degree, and controlling the intake pump and the exhaust pump to operate at a target power.

[0056] Specifically, Figure 2 and Figure 3 As shown, the door 12 is connected to the cooking box 10. During the heating process of food, the door 12 is closed to seal the cooking cavity 11. After the food in the cooking cavity 11 is cooked, or during the heating process of the food in the cooking cavity 11, the user can open the door 12 to take out the food. It can be understood that the greater the opening degree of the door 12, the greater the opening angle of the door 12 relative to the cooking box 10, the greater the communication range between the cooking cavity 11 and the outside, and the more high-temperature gas will emerge from the cooking cavity 11.

[0057] Continue to refer Figure 2 and Figure 3 In this embodiment, a door control detection module 13 may be provided on a side of the cooking box 10 close to the box door 12 to detect the opening degree of the box door 12 , so that the opening degree of the box door 12 may be obtained through the door control detection module 13 .

[0058] The door control detection module 13 may be a pressure-sensitive sensor, a capacitive sensor, a magnetic sensor or other devices, but is not limited thereto.

[0059] It can be understood that the opening degree of the first solenoid valve 16 determines the flow rate of the external gas of the cooking cavity 11 in the channel of the air intake pipe 14. When the first solenoid valve 16 is closed, the external gas of the cooking cavity 11 cannot enter the cooking cavity 11 through the air intake pipe 14. When the first solenoid valve 16 is opened, the external gas of the cooking cavity 11 can enter the cooking cavity 11 through the air intake pipe 14. The greater the opening degree of the first solenoid valve 16, the greater the flow rate of the external gas of the cooking cavity 11 in the channel of the air intake pipe 14 will be.

[0060] The opening degree of the second solenoid valve 17 determines the flow rate of the internal gas of the cooking cavity 11 in the exhaust pipe 15 channel. When the second solenoid valve 17 is closed, the internal gas of the cooking cavity 11 cannot be discharged from the cooking cavity 11 through the exhaust pipe 15. When the second solenoid valve 17 is opened, the internal gas of the cooking cavity 11 can be discharged from the cooking cavity 11 through the exhaust pipe 15. The greater the opening degree of the second solenoid valve 17 is, the greater the flow rate of the internal gas of the cooking cavity 11 in the exhaust pipe 15 channel will be.

[0061] The power of the air intake pump 18 determines the flow rate of the external gas of the cooking cavity 11 in the air intake pipe 14 channel. The greater the power of the air intake pump 18, the faster the flow rate of the external gas of the cooking cavity 11 in the air intake pipe 14 channel, and the greater the flow rate of the external gas of the cooking cavity 11 in the air intake pipe 14 channel.

[0062] The power of the exhaust pump 19 determines the flow rate of the gas inside the cooking cavity 11 in the exhaust pipe 15 channel. The greater the power of the exhaust pump 19, the faster the flow rate of the gas inside the cooking cavity 11 in the exhaust pipe 15 channel, and the greater the flow rate of the gas inside the cooking cavity 11 in the exhaust pipe 15 channel.

[0063] In this embodiment, the target opening degrees of the first solenoid valve 16 and the second solenoid valve 17 and the target powers of the intake pump 18 and the exhaust pump 19 can be controlled according to the opening degree of the chamber door 12 .

[0064] Specifically, after the food in the cooking cavity 11 is cooked, or during the heating process of the food in the cooking cavity 11, there is a large amount of hot air in the cooking cavity 11. When the user opens the door 12, the high-temperature gas in the cooking cavity 11 will rush out of the door 12 and scald the user. The door control detection module 13 obtains the opening degree of the door 12. When the opening degree of the door 12 is 0%, that is, the door 12 is in a closed state, the target opening degree of the first solenoid valve 16 and the second solenoid valve 17 is determined to be 0%, and the target power of the air intake pump 18 and the exhaust pump 19 is 0. At this time, the external air of the cooking cavity 11 cannot enter the cooking cavity 11 through the air intake pipe 14, and the internal air of the cooking cavity 11 cannot be discharged from the cooking cavity 11 through the exhaust pipe 15. When the opening degree of the door 12 is 100%, that is, the door 12 is in an open state, the target opening degree of the first solenoid valve 16 and the second solenoid valve 17 is determined to be the maximum opening degree, and the target power of the air intake pump 18 and the exhaust pump 19 is the maximum power. At this time, the gas inside the cooking cavity 11 is discharged from the cooking cavity 11 through the exhaust pipe 15, and the air outside the cooking cavity 11 is replenished into the cooking cavity 11 through the air intake pipe 14, forming a circulation of hot air flow inside the cooking cavity 11 and air flow outside the cooking cavity 11, so as to play a role in heat dissipation and cooling, and prevent high-temperature gas from rushing out of the door 12 and scalding the user. At the same time, the air outside the cooking cavity 11 is replenished into the cooking cavity 11 through the air intake pipe 14, which can also neutralize the negative pressure formed by the exhaust pipe 15 exhausting the hot air, so as to facilitate the user to open the door.

[0065] It should be noted that the control method of the cooking appliance provided in the present embodiment controls the exhaust of the gas inside the cooking cavity 11 and the replenishment of air outside the cooking cavity 11 according to the opening degree of the oven door 12. Even when the food in the cooking cavity 11 is being heated, as long as the user opens the oven door 12, the first solenoid valve 16, the second solenoid valve 17, the air intake pump 18 and the exhaust pump 19 are controlled to extract the high-temperature gas in the cooking cavity 11 in time. Therefore, in the scenario where the user directly opens the oven door 12 without performing a standardized operation (for example, the user opens the oven door 12 before cooking is finished or a child accidentally opens the oven door 12, etc.), it is possible to prevent the high-temperature gas from rushing out of the oven door 12 and scalding the user.

[0066] In summary, the control method of the cooking appliance provided in the embodiment of the present invention obtains the opening degree of the cabinet door through the door control detection module, obtains the target opening degree of the first solenoid valve and the second solenoid valve, and the target power of the intake pump and the exhaust pump according to the opening degree of the cabinet door, and controls the first solenoid valve and the second solenoid valve to open at the target opening degree, and controls the intake pump and the exhaust pump to operate at the target power, so as to timely control the discharge of high-temperature gas inside the cooking cavity and the replenishment of air outside the cooking cavity according to the opening degree of the cabinet door, and perform heat dissipation and cooling in the cooking cavity, thereby preventing high-temperature gas from rushing out of the cabinet door and scalding the user when the cabinet door is opened.

[0067] Optionally, the greater the opening degree of the box door, the greater the target opening degree of the first solenoid valve and the second solenoid valve; and / or, the greater the opening degree of the box door, the greater the target power of the intake pump and the exhaust pump.

[0068] When the door is opened to a small extent, the hot air in the cooking cavity through the door is small. At this time, the first solenoid valve and the second solenoid valve can be controlled to open at a small target opening degree, so that the gas outside the cooking cavity can enter the cooking cavity through the air inlet pipe at a small flow rate, and the gas inside the cooking cavity can be discharged from the cooking cavity through the exhaust pipe at a small flow rate, so that when the user pulls the door by mistake and does not fully open the door, the hot air can be prevented from hitting the face, and the cooking cavity can be quickly warmed up, so that it is convenient to continue cooking food. When the door is opened to a large extent, the hot air in the cooking cavity through the door is large. At this time, the first solenoid valve and the second solenoid valve can be controlled to open at a large target opening degree, so that the gas outside the cooking cavity can enter the cooking cavity through the air inlet pipe at a large flow rate, and the gas inside the cooking cavity can be discharged from the cooking cavity through the exhaust pipe at a large flow rate, so that when the user opens the door, the high-temperature gas in the cooking cavity can be prevented from rushing out of the door and scalding the user.

[0069] Similarly, optionally, when the door is opened to a small extent, the air intake pump and the exhaust pump can be controlled to work at a smaller target power, so that the gas outside the cooking cavity can enter the cooking cavity through the air intake pipe at a smaller flow rate, and the gas inside the cooking cavity can be discharged from the cooking cavity through the exhaust pipe at a smaller flow rate, so that when the user pulls the door by mistake and does not fully open the door, hot air can be prevented from blowing in the face, and the cooking cavity can be quickly warmed up, so that it is convenient to continue cooking food. When the door is opened to a large extent, the air intake pump and the exhaust pump can be controlled to work at a larger target power, so that the gas outside the cooking cavity can enter the cooking cavity through the air intake pipe at a larger flow rate, and the gas inside the cooking cavity can be discharged from the cooking cavity through the exhaust pipe at a larger flow rate, so that when the user opens the door, the high-temperature gas in the cooking cavity can be prevented from rushing out of the door and scalding the user.

[0070] Optionally, the door opening degree is obtained through the door control detection module, including:

[0071] The closing pressure value between the box door and the box body is obtained through the door control detection module.

[0072] The opening degree of the door is obtained according to the closing pressure value, wherein the smaller the closing pressure value is, the greater the opening degree of the door is.

[0073] Specifically, Figure 2 and Figure 3 As shown, the door control detection module 13 can be fixed to a side of the cooking box 10 close to the door 12 to detect the fit between the door 12 and the door control detection module 13 (ie, the cooking box 10 ).

[0074] Exemplarily, the door control detection module 13 may use a pressure-sensitive sensor. When the cooking appliance is working, the user pulls the handle of the cabinet door 12, and the closing pressure between the cabinet door 12 and the door control detection module 13 decreases. The door control detection module 13 can transmit the instantaneous closing pressure value to the controller of the cooking appliance. The controller controls the target opening degree of the first solenoid valve 16 and the second solenoid valve 17 and the target power of the intake pump 18 and the exhaust pump 19 according to the closing pressure value. The smaller the closing pressure value, the greater the opening degree of the cabinet door 12. When the closing pressure value is zero, the cabinet door 12 is fully opened. At this time, the first solenoid valve 16 and the second solenoid valve 17 can be opened to the maximum opening degree, and the intake pump 18 and the exhaust pump 19 can be opened to the maximum power to prevent the high-temperature gas in the cooking cavity from rushing out of the cabinet door and scalding the user.

[0075] Furthermore, the relationship between the closing pressure value and the target power of the intake pump 18 and the exhaust pump 19, and the target opening degree of the first solenoid valve 16 and the second solenoid valve 17 can be a nonlinear relationship. The smaller the instantaneous closing pressure value (i.e., the greater the force used by the user to open the door 12), the greater the change in the target power of the intake pump 18 and the exhaust pump 19 caused by the pressure change, and the change in the target opening degree of the first solenoid valve 16 and the second solenoid valve 17. The specific relationship can be represented by a functional relationship K=G(a), a=F0-F. Among them, K is the opening degree of the door 12 (%), F0 is the force required by the user to completely open the door 12, and F is the real-time closing pressure value on the door control detection module 13 (0≤F≤F0), then a is the real-time force used by the user to pull the door when the door 12 is closed, that is, the pulling force of the user on the door 12.

[0076] Figure 4 A schematic diagram of a functional relationship between the degree of opening of a door and the pulling force of the door by the user provided in an embodiment of the present invention, such as Figure 4 As shown, the horizontal axis is the user's pulling force a on the door, and the vertical axis is the opening degree K of the door. When the door is closed normally, F=F0, a=0, K=G(0)=0, at this time, the target opening degree of the first solenoid valve 16 and the second solenoid valve 17 is 0, that is, the first solenoid valve 16 and the second solenoid valve 17 are completely closed, and the target power of the intake pump 18 and the exhaust pump 19 is 0, that is, the intake pump 18 and the exhaust pump 19 are not started; and when the door is just opened, F=0, a=F0, K=G(F0)=100%, at this time, the target opening degree of the first solenoid valve 16 and the second solenoid valve 17 is the maximum opening degree, that is, the first solenoid valve 16 and the second solenoid valve 17 are completely opened, and the target power of the intake pump 18 and the exhaust pump 19 is the maximum power, that is, the intake pump 18 and the exhaust pump 19 are opened to the maximum power.

[0077] Among them, Figure 4 As shown, when a<F1, the unit increment of K is small, and when a>F1, the unit increment of K is large and gradually increases. The specific values ​​of F0 and F1 can be obtained through multiple simulation tests, and the embodiment of the present invention does not make specific limitations on this.

[0078] It should be noted that the functional relationship between the opening degree of the above-mentioned door and the pulling force of the door by the user is only for illustration, and those skilled in the art can set the above-mentioned functional relationship according to actual needs.

[0079] In addition, the present invention is not limited to obtaining the degree of opening of the box door by the closing pressure value between the box door 12 and the box body 10. In another embodiment, the door control detection module 13 may also be provided to include a capacitive sensor, wherein two electrodes of the capacitive sensor are respectively provided on the box door 12 and the box body 10. The distance between the box door 12 and the box body 10 will change the capacitance value between the two electrodes. The greater the distance between the box door 12 and the box body 10, the greater the degree of opening of the box door 12. Thus, the degree of opening of the box door 12 can be obtained by the capacitance value of the capacitive sensor.

[0080] In another embodiment, the door control detection module 13 may also be configured to include a magnetic sensor, and the magnetic sensor and the magnet are respectively arranged on the box door 12 and the box body 10. The distance between the box door 12 and the box body 10 will change the magnetic value detected by the magnetic sensor. The greater the distance between the box door 12 and the box body 10, the greater the degree of opening of the box door 12. Therefore, the degree of opening of the box door 12 can be obtained by the magnetic value detected by the magnetic sensor. However, it is not limited to this, and those skilled in the art can make settings according to actual needs.

[0081] The control method of the cooking appliance provided in the embodiment of the present invention can, on the one hand, prevent the user from suddenly opening the door of the cooking appliance when the cooking appliance is working, resulting in the air intake pump and the exhaust pump not being started in time, causing part of the high-temperature gas in the cooking cavity to escape to the door and cause harm to the user; on the other hand, it can also prevent the situation where a child accidentally pulls the door of the cooking appliance but does not open it during the operation of the cooking appliance, and the door control detection module 13 is too sensitive, resulting in false detection and operation.

[0082] Continue to refer Figure 2 and Figure 3 Optionally, a temperature sensor 25 is provided in the cooking cavity 11 .

[0083] Before obtaining the opening degree of the door 12 through the door control detection module 13, the following steps are also included:

[0084] The real-time temperature in the cooking cavity 11 is acquired through the temperature sensor 25 .

[0085] If the real-time temperature in the cooking cavity 11 is greater than the first preset threshold, it is determined whether the cooking process is ended or paused.

[0086] The door control detection module 13 obtains the opening degree of the door 12, including:

[0087] When the real-time temperature in the cooking cavity 11 is greater than the first preset threshold value and the cooking program is not ended or paused, the opening degree of the door 12 is acquired through the door control detection module 13 .

[0088] Among them, Figure 2 and Figure 3As shown, the temperature sensor 25 may be disposed inside the cooking cavity 11 to detect the temperature inside the cooking cavity 11 .

[0089] Figure 5 A schematic diagram of the structure of another cooking appliance provided by an embodiment of the present invention is shown in FIG. Figure 2 , Figure 3 and Figure 5 As shown, exemplarily, when the cooking appliance starts working, the controller of the cooking appliance can obtain the real-time temperature in the cooking cavity 11 through the temperature sensor 25, and determine whether the real-time temperature in the cooking cavity 11 is greater than the first preset threshold value. If the real-time temperature in the cooking cavity 11 is greater than the first preset threshold value, it means that the current temperature in the cooking cavity 11 is high. If the user opens the door 12, hot air may hit the face. At this time, the controller determines whether the cooking program is ended or paused. If the cooking program is not ended or paused, that is, the food in the cooking chamber 11 is in the cooking process, the opening degree of the cabinet door 12 is obtained through the gate detection module 13, and the target opening degree of the first solenoid valve 16 and the second solenoid valve 17, as well as the target power of the intake pump 18 and the exhaust pump 19 are obtained according to the opening degree of the cabinet door 12, and the first solenoid valve 16 and the second solenoid valve 17 are controlled to open at the target opening degree, and the intake pump 18 and the exhaust pump 19 are controlled to operate at the target power, so as to control the working states of the first solenoid valve 16, the second solenoid valve 17, the intake pump 18 and the exhaust pump according to the opening degree of the cabinet door 12, thereby preventing the user from suddenly opening the cabinet door 12 during the cooking program, causing the high-temperature gas in the cooking chamber 11 to escape to the cabinet door and cause harm to the user.

[0090] Among them, the first preset threshold is a relatively high temperature. Technical personnel in this field can set it according to the temperature at which the hot air generated by the cooking cavity 11 may cause safety hazards to the user, such as setting it to 90°C~120°C. The embodiment of the present invention does not make any specific limitations on this.

[0091] Optionally, after controlling the first solenoid valve and the second solenoid valve to open at a target opening degree, and controlling the intake pump and the exhaust pump to operate at a target power, the method further includes:

[0092] The real-time temperature in the cooking chamber is obtained through the temperature sensor.

[0093] When the real-time temperature in the cooking cavity is less than or equal to a first preset threshold, the first solenoid valve, the second solenoid valve, the air intake pump and the exhaust pump are controlled to be closed.

[0094] For details, please refer to Figure 5As described above, when the real-time temperature in the cooking cavity is greater than the first preset threshold and the cooking program has not ended or paused, the target opening degrees of the first solenoid valve and the second solenoid valve and the target powers of the air intake pump and the exhaust pump are controlled according to the opening degree of the door, and then the real-time temperature in the cooking cavity continues to be obtained through the temperature sensor. If the real-time temperature in the cooking cavity is still greater than the first preset threshold, the target opening degrees of the first solenoid valve and the second solenoid valve and the target powers of the air intake pump and the exhaust pump continue to be controlled according to the opening degree of the door until the real-time temperature in the cooking cavity is less than or equal to the first preset threshold, and the first solenoid valve, the second solenoid valve, the air intake pump and the exhaust pump are closed. At this time, the temperature in the cooking cavity is relatively low, and even if the user suddenly opens the door, hot air will not hit the face and cause scalding of the user, thereby avoiding scalding of the user while reducing power consumption.

[0095] Among them, when the target opening degree of the first solenoid valve and the second solenoid valve and the target power of the air intake pump and the exhaust pump are controlled according to the opening degree of the oven door, when the user directly opens the oven door during the cooking process, the controller controls the first solenoid valve and the second solenoid valve to open at the maximum opening degree, and controls the air intake pump and the exhaust pump to operate at maximum power. At the same time, the cooking appliance stops working, that is, stops heating the food, to achieve a rapid cooling effect, thereby preventing the high-temperature gas in the cooking cavity from rushing out of the oven door and scalding the user.

[0096] Optionally, after determining whether the cooking process is finished or paused, the method further includes:

[0097] If the cooking program is ended or paused, the first solenoid valve and the second solenoid valve are controlled to open at a maximum opening degree, and the intake pump and the exhaust pump are controlled to operate at maximum power.

[0098] For details, please refer to Figure 2 , Figure 3 and Figure 5 When the real-time temperature in the cooking cavity 11 is greater than the first preset threshold value and the cooking program has ended or paused, the controller controls the first solenoid valve 16 and the second solenoid valve 17 to open to the maximum degree, and controls the air intake pump 18 and the exhaust pump 19 to operate at maximum power to achieve a rapid cooling effect, thereby preventing the high-temperature gas in the cooking cavity 11 from rushing out of the door 12 and scalding the user when the user opens the door 12 to take food.

[0099] Optionally, after controlling the first solenoid valve and the second solenoid valve to open to the maximum opening degree, and controlling the intake pump and the exhaust pump to operate at the maximum power, the method further includes:

[0100] The real-time temperature in the cooking chamber is obtained through the temperature sensor.

[0101] When the real-time temperature in the cooking cavity is less than or equal to a first preset threshold, the first solenoid valve, the second solenoid valve, the air intake pump and the exhaust pump are controlled to be closed.

[0102] For details, please refer to Figure 5 As described above, when the real-time temperature in the cooking cavity is greater than the first preset threshold and the cooking program ends or is paused, the controller controls the first solenoid valve and the second solenoid valve to open at the maximum opening degree, and controls the air intake pump and the exhaust pump to run at maximum power, and then continues to obtain the real-time temperature in the cooking cavity through the temperature sensor. If the real-time temperature in the cooking cavity is still greater than the first preset threshold, the first solenoid valve and the second solenoid valve continue to be controlled to open at the maximum opening degree, and the air intake pump and the exhaust pump are controlled to run at maximum power until the real-time temperature in the cooking cavity is less than or equal to the first preset threshold, and the first solenoid valve, the second solenoid valve, the air intake pump and the exhaust pump are closed. At this time, the temperature in the cooking cavity is relatively low. When the user opens the door to take food, it can avoid scalding the user and reduce power consumption.

[0103] Based on the same inventive concept, the embodiment of the present invention also provides a cooking utensil, such as Figure 2 and Figure 3 As shown, the cooking appliance provided in the embodiment of the present invention includes a cooking box 10, a cooking cavity 11, a box door 12, a door control detection module 13, an air intake pipe 14, an exhaust pipe 15, a first solenoid valve 16, a second solenoid valve 17, an air intake pump 18 and an exhaust pump 19. The door control detection module 13 is used to detect the opening degree of the box door 12, the first solenoid valve 16 is arranged on the air intake pipe 14, the second solenoid valve 17 is arranged on the exhaust pipe 15, the air intake pump 18 is used to draw the gas outside the cooking cavity 11 into the cooking cavity 11 through the air intake pipe 14, and the exhaust pump 15 is used to discharge the gas inside the cooking cavity 11 out of the cooking cavity 11 through the exhaust pipe 15. The cooking appliance also includes a controller (not shown in the figure), which is respectively connected to the gate detection module 13, the first solenoid valve 16, the second solenoid valve 17, the intake pump 18 and the exhaust pump 19. The controller is used to execute the control method of the cooking appliance provided by any of the above embodiments. Therefore, the cooking appliance provided by the embodiment of the present invention has the technical effect of the technical solution in any of the above embodiments, and the structures that are the same or corresponding to the above embodiments and the explanation of terms are not repeated here.

[0104] Continue to refer Figure 2 and Figure 3 Optionally, the air inlet pipe 14 is arranged above the cooking cavity 11 , the air outlet 141 of the air inlet pipe 14 is located at the door 12 , and the air outlet 141 of the air inlet pipe 14 is arranged toward one side of the door 12 .

[0105] Among them, after the food in the cooking cavity 11 is cooked, or during the heating process of the food in the cooking cavity 11, there is a large amount of hot air in the cooking cavity 11. The target opening degree of the first solenoid valve 16 and the second solenoid valve 17, as well as the target power of the intake pump 18 and the exhaust pump 19 can be controlled according to the opening degree of the cabinet door 12. When the user opens the cabinet door 12, the first solenoid valve 16, the second solenoid valve 17, the intake pump 18 and the exhaust pump 19 are opened, and the high-temperature gas inside the cooking cavity 11 is discharged through the exhaust pipe 15 to prevent the hot air from rushing out of the cabinet door 12 and scalding the user. At the same time, the air outside the cooking cavity 11 is replenished into the cooking cavity 11 through the intake pipe 14, forming a circulation of the hot air flow in the cooking cavity 11 and the air flow outside the cooking cavity 11, which can better play a role in heat dissipation and cooling. At the same time, it can also neutralize the negative pressure formed by the exhaust pipe 15 exhausting the hot air, making it easier for the user to open the door.

[0106] Continue to refer Figure 2 and Figure 3 Furthermore, the air outlet 141 of the air inlet pipe 14 is located above the door 12, and the air outlet 141 of the air inlet pipe 14 is arranged downward. When the user opens the door 12, the air outside the cooking cavity 11 forms an airflow through the air inlet pipe 14, and is blown out through the air outlet 141 to the position where the door 12 is opened. The blown air can counteract the hot air in the cooking cavity 11 that is emitted above the door 12, thereby changing the direction of the hot air flow and preventing the hot air from hitting the face and scalding the user.

[0107] Continue to refer Figure 2 and Figure 3 Optionally, the cooking box 10 includes a top shell 26 located above the cooking cavity 11, the top shell 26 includes an outer protrusion 27 protruding from the cooking cavity 11 in a horizontal direction, and the air outlet 141 of the air inlet pipe 14 is arranged on the surface of the outer protrusion 27 on the side close to the door 12.

[0108] Specifically, Figure 2 and Figure 3 As shown, the door 12 can be set as a downward flip door, and when the door 12 is closed, the convex part 27 of the top shell 26 is located above the door 12. The air inlet pipe 14 can be partially arranged in the top shell 26, and the air outlet 141 of the air inlet pipe 14 is arranged on the lower surface of the convex part 27, so that when the door 12 is closed, the air outlet 141 is located above the door 12. After the food in the cooking cavity 11 is cooked, or during the heating process of the food in the cooking cavity 11, if the user opens the door 12, the convex part 27 can block part of the hot air from escaping upwards, and at the same time, the air outlet 141 of the air inlet pipe 14 arranged on the lower surface of the convex part 27 blows out airflow downwards, which is counteracted by the hot air escaping from the cooking cavity 11, thereby changing the direction of the hot air flow to prevent the hot air from hitting the face and scalding the user.

[0109] Continue to refer Figure 2 and Figure 3 Optionally, the exhaust pipe 15 is located at the upper part of the cooking cavity 11 , and the air inlet 151 of the exhaust pipe 15 is arranged at the door 12 .

[0110] Specifically, Figure 2 and Figure 3 As shown, when the user opens the oven door 12, the hot air inside the cooking cavity 11 will escape upward through the gap of the oven door 12. In this embodiment, by arranging the exhaust pipe 15 at the upper part of the cooking cavity 11 and the air inlet 151 of the exhaust pipe 15 at the oven door 12, the hot air escaped upward through the gap of the oven door 12 can be discharged through the exhaust pipe 15, thereby preventing the hot air from scalding the user.

[0111] Continue to refer Figure 2 and Figure 3 Optionally, one end of the exhaust pipe 15 close to the door 12 is bent downward.

[0112] Among them, Figure 2 and Figure 3 As shown, by bending one end of the exhaust pipe 15 close to the oven door 12 downward, when the user opens the oven door 12, the hot air that escapes upward from the cooking cavity 11 can be discharged through the exhaust pipe 15, thereby reducing the hot air that emerges upward and preventing the user from being scalded by the hot air that emerges when the oven door 12 is opened.

[0113] Continue to refer Figure 2 and Figure 3 Optionally, a side of the cooking box 10 away from the box door 12 is provided with a range hood air cavity 21, a smoke exhaust fan 22 is provided in the range hood air cavity 21, a smoke exhaust duct 23 is provided at the air outlet of the smoke exhaust fan 22, an air outlet 152 of the exhaust pipe 15 is located in the range hood air cavity 21, and the air outlet 152 of the exhaust pipe 15 is located on the side of the smoke exhaust fan 22 away from the smoke exhaust duct 23.

[0114] Specifically, Figure 2 and Figure 3 As shown, taking the cooking utensil as an integrated stove as an example, a smoke exhaust fan 22 is provided in the hood air cavity 21 of the integrated stove. When the smoke exhaust fan 22 is turned on, the fumes in the kitchen can be discharged through the hood air cavity 21 and the smoke exhaust duct 23.

[0115] In this embodiment, the air outlet 152 of the exhaust pipe 15 is arranged above the exhaust fan 22 in the air cavity 21 of the range hood, so as to communicate with the air cavity 21 of the range hood. When the user opens the door 12, the exhaust fan 22 can be started to form a negative pressure in the air cavity 21 of the range hood, so that the hot air in the cooking cavity 11 is replenished into the air cavity 21 of the range hood through the exhaust pipe 15 and discharged through the exhaust duct 23, so that the hot air in the cooking cavity 11 is extracted, thereby preventing the hot air from escaping through the door 12 and scalding the user.

[0116] Continue to refer Figure 2 and Figure 3 Optionally, one end of the air outlet 152 of the exhaust pipe 15 is bent toward the side of the smoke exhaust fan 22 so that the hot air extracted from the cooking cavity 11 can be discharged through the smoke exhaust duct 23.

[0117] Continue to refer Figure 2 and Figure 3 Optionally, the air inlet 142 of the air inlet pipe 14 is located in the smoke exhaust fan air cavity 21 , and the air inlet 142 of the air inlet pipe 14 is located on a side of the exhaust pipe 15 away from the smoke exhaust fan 22 .

[0118] Specifically, Figure 2 and Figure 3 As shown, by setting the air inlet 142 of the air inlet pipe 14 in the range hood air cavity 21 to communicate with the range hood air cavity 21, when the user opens the door 12, the air in the range hood air cavity 21 is blown into the cooking cavity 11 through the air inlet pipe 14, and forms a counterattack with the hot air rising upward from the cooking cavity 11, thereby changing the direction of the hot air flow and preventing the hot air from hitting the face and scalding the user.

[0119] The air inlet 142 of the air inlet pipe 14 is arranged above the exhaust pipe 15 , so as to prevent the hot air discharged from the exhaust pipe 15 from being blown into the cooking cavity 11 through the air inlet pipe 14 .

[0120] Further, continue to refer to Figure 2 and Figure 3 One end of the air inlet 142 of the air inlet pipe 14 is bent toward a side away from the smoke exhaust fan 22 , so that the airflow in the smoke exhaust fan air cavity 21 can be blown into the cooking cavity 11 through the air inlet pipe 14 .

[0121] Continue to refer Figure 2 and Figure 3 Optionally, a fume filter 24 is provided on the side of the range hood air chamber 21 away from the air inlet pipe 14 .

[0122] Specifically, Figure 2 and Figure 3 As shown, after the exhaust fan 22 is started, the oil smoke in the kitchen can be discharged through the hood air chamber 21 and the exhaust duct 23. In this embodiment, an oil smoke filter 24 is arranged above the air inlet pipe 14 to filter the oil smoke entering the hood air chamber 21, thereby preventing the oil smoke from entering the cooking chamber 11 through the air inlet pipe 14 and contaminating the food.

[0123] Continue to refer Figure 2 and Figure 3 Optionally, the controller may be disposed at the outer protrusion 27 of the top shell 26, but is not limited thereto.

[0124] Continue to refer Figure 2 and Figure 3Optionally, the door control detection module 13 is located between the box door 12 and the box body 10, and the door control detection module 13 includes any one of a pressure-sensitive sensor, a capacitive sensor and a magnetic sensor.

[0125] Exemplarily, the door control detection module 13 may use a pressure-sensitive sensor, which may be fixed to a side of the cooking box 10 close to the door 12 to detect the fit between the door 12 and the door control detection module 13 (i.e., the cooking box 10). When the user pulls the door 12 handle, the closing pressure between the door 12 and the door control detection module 13 decreases, and the door control detection module 13 may transmit the instantaneous closing pressure value to the controller of the cooking appliance, and the controller obtains the degree of opening of the door according to the closing pressure value, wherein the smaller the closing pressure value, the greater the degree of opening of the door 12, and when the closing pressure value is zero, the door 12 is fully opened.

[0126] In addition, the present invention is not limited to obtaining the opening degree of the box door 12 by the closing pressure value between the box door 12 and the box body 10. In another embodiment, the door control detection module 13 may also be provided to include a capacitive sensor, and the two electrodes of the capacitive sensor are respectively provided on the box door 12 and the box body 10. The distance between the box door 12 and the box body 10 will change the capacitance value between the two electrodes. The greater the distance between the box door 12 and the box body 10, the greater the opening degree of the box door 12, so that the opening degree of the box door 12 can be obtained by the capacitance value of the capacitive sensor.

[0127] In another embodiment, the door control detection module 13 may also be configured to include a magnetic sensor, and the magnetic sensor and the magnet are respectively arranged on the box door 12 and the box body 10. The distance between the box door 12 and the box body 10 will change the magnetic value detected by the magnetic sensor. The greater the distance between the box door 12 and the box body 10, the greater the degree of opening of the box door 12. Therefore, the degree of opening of the box door 12 can be obtained by the magnetic value detected by the magnetic sensor. However, it is not limited to this, and those skilled in the art can make settings according to actual needs.

[0128] Continue to refer Figure 2 and Figure 3 Optionally, a temperature sensor 25 is provided in the cooking cavity 11, and the temperature sensor 25 is connected to the controller.

[0129] Among them, Figure 2 and Figure 3 As shown, the temperature sensor 25 may be disposed inside the cooking cavity 11 to detect the temperature inside the cooking cavity 11 .

[0130] Continue to refer Figure 2 and Figure 3Optionally, at the end of the normal cooking program, the controller controls the first solenoid valve 16 and the second solenoid valve 17 to open, and the air intake pump 18 and the exhaust pump 19 to start working, and the external gas of the cooking cavity 11 is blown into the cooking cavity 11 through the oil fume filter 24, the air intake pipe 14, the air intake pump 18 and the first solenoid valve 16 in sequence, and forms a counter-attack with the hot air from the cooking cavity 11 to the top of the door 12, thereby changing the direction of the hot air flow to avoid the hot air blowing on the face and scalding the user. At the same time, the high-temperature gas inside the cooking cavity 11 is discharged outward through the exhaust pipe 15, the second solenoid valve 17, the exhaust pump 19, the range hood air chamber 21 and the exhaust duct 23 in sequence, ensuring that the high-temperature gas inside the cooking cavity 11 can be discharged in time to avoid the hot air blowing on the face and scalding the user.

[0131] In addition, during the cooking process, the controller obtains the opening degree of the oven door 12 through the door control detection module 13 to judge the user's door opening behavior. If an abnormal door opening occurs, the first solenoid valve 16, the second solenoid valve 17, the air intake pump 18 and the exhaust pump 19 are controlled to be linked to each other, and measures such as extracting the hot air in the cooking cavity 11 and drawing the outside air into the cooking cavity 11 to offset the hot air are taken in time, which can solve the safety hazard of children accidentally opening the oven door.

[0132] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0133] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
