[0055] In the related art, a strong exhaust structure is generally introduced into cooking equipment such as a steamer or a steam-bake combination machine to exhaust the high-temperature steam in the cooking cavity before the user opens the door to prevent scalding the user. However, for embedded cooking equipment, except for the front facade, the rest is embedded inside the cabinet. The strong exhaust structure currently used mostly draws air from the inside of the equipment or the cabinet. Relatively speaking, the air inside the cabinet is relatively closed and mold is prone to grow. Therefore, the cooking equipment is forced to exhaust steam from the cavity by taking in air from the room.

[0056] Among them, the exhaust fan and exhaust valve body required for strong exhaust may fail. For example, when the exhaust valve body can be opened normally but the exhaust fan fails, the steam will flow back from the pipe and overflow from the exhaust fan port during the exhaust process. When the steam diffuses in the cavity with electrical structure outside the inner tank, it may cause a short circuit of the electrical gas parts, causing safety hazards; when the exhaust fan is normal and the exhaust valve body cannot be opened, the exhaust process is invalid, and there is still a lot of steam when the door is opened, resulting in a decrease in user experience. Therefore, it is necessary to promptly feedback the failure of the exhaust structure, and to conduct alarms and maintenance to avoid safety problems.

[0057] In response to the above technical problems, the embodiments of the present application provide a method for detecting a steam exhaust function and a cooking device. The method for detecting a steam exhaust function includes: running the cooking device, closing the steam exhaust valve and obtaining the exhaust temperature data on the inlet side of the exhaust valve; judging whether the exhaust valve is faulty based on the exhaust temperature data, and controlling the exhaust fan according to the judgment result. In this way, the present application can judge whether the exhaust structure has failed, and provide timely feedback when the exhaust structure has failed, reminding the user to perform maintenance, preventing steam from entering the electrical space outside the inner pot and condensing to produce condensed water, causing damage to electrical components, helping to avoid greater losses, ensuring the safe use of cooking equipment, and improving user experience.

[0058] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0059] Reference Figure 1 and Figure 2 As shown, an embodiment of the present application provides a cooking device 100 , including a housing 110 , an exhaust fan 120 , an exhaust valve 130 , and a controller, wherein the housing 110 has a cooking cavity 140 .

[0060] In the embodiment of the present application, there is no limitation on the type of the cooking device 100. For example, the cooking device 100 of the present embodiment may be an oven, a steamer, a steam-bake-in-one machine, or a steam-bake-in-one machine. In the present embodiment, the cooking device 100 is mainly described as a steam-bake-in-one machine.

[0061] The steam-bake combination machine integrates the functions of a gas stove, a steamer and an oven. As one machine is equivalent to multiple kitchen appliances with independent functions, it can achieve frying / stewing while steaming / baking, freeing up kitchen space. The principle is to use the heating system of the appliance to heat water into steam, and use the steam to steam, bake and cook food.

[0062] It should be noted that the shell 110 has an inner liner, and the cooking cavity 140 is formed in the inner liner. The inner liner is one of the core components of the steam-bake combination machine, and the inner liner is used to cook food. Among them, the material of the inner liner is not limited. Exemplarily, the material of the inner liner can be stainless steel, and the stainless steel inner liner can withstand higher temperature water and detergent. At the same time, stainless steel has antibacterial properties and is easy to clean; or, the material of the inner liner can be plastic, and the plastic inner liner has certain impact resistance and electrical insulation properties; or, the material of the inner liner can be ceramic, which has the advantages of smoothness, slow deterioration, and corrosion resistance, and can also increase the washing effect. This embodiment is not limited to this.

[0063] In the present application, refer to Figure 1 and Figure 2 As shown, the exhaust fan 120 and the exhaust valve 130 are arranged outside the cooking cavity 140. In this way, on the one hand, it is convenient for the exhaust fan 120 to draw air from the room, which helps to blow air into the cooking cavity 140 and squeeze out the steam in the cooking cavity 140; on the other hand, this design reduces the number of complex components inside the cooking cavity 140, making the device more concise, easy to clean and maintain; on the other hand, the external arrangement also facilitates the maintenance and replacement of the exhaust fan 120 and the exhaust valve 130, reducing the maintenance cost and further ensuring the safety of the device.

[0064] In the embodiment of the present application, the exhaust fan 120 is connected to the inlet of the exhaust valve 130, and the outlet of the exhaust valve 130 is connected to the cooking cavity 140. Figure 1 and Figure 2 As shown, the cooking device 100 may further include an air inlet pipe 160 and a connecting pipe 170 , wherein the exhaust fan 120 is connected to the exhaust valve 130 via the connecting pipe 170 , and the exhaust valve 130 is connected to the cooking cavity 140 via the air inlet pipe 160 .

[0065] There is no limitation on the type of the connecting pipe 170. For example, the connecting pipe 170 may be a reducer; or, the connecting pipe 170 may be an elbow; or, the connecting pipe 170 may be a three-way joint. This embodiment does not limit this. In addition, there is no limitation on the type of the air intake pipe 160, which may be selected according to actual needs.

[0066] In the embodiment of the present application, the connecting pipe 170 is mainly described as a reducer. In this way, the reducer can connect pipes of different diameters, realize smooth connection between pipes, and ensure efficient transmission of fluid or gas; in addition, the reducer can also reduce the resistance of the pipeline system, improve the flow efficiency and stability of the pipeline system, and help reduce operating costs and vibration noise.

[0067] In the embodiment of the present application, the cooking device 100 may include an exhaust pipe 190, an exhaust air duct, a condensation chamber, a condensation water return pipe, and a condensation water return box. The exhaust air duct is located outside the cooking cavity 140, the exhaust air duct is connected to the cooking cavity 140 through the exhaust pipe 190, and the condensation chamber is connected to the exhaust air duct; the condensation water return box is arranged in the condensation chamber and is used to receive condensation water; the first end of the condensation water return pipe is connected to the condensation water return box, and the second end of the condensation water return pipe can be connected to the water inlet pipe. In this way, it is conducive to realizing the recycling of water supply and improving the utilization rate of water supply.

[0068] The exhaust path of the embodiment of the present application is as follows: the exhaust fan 120 blows air into the cooking cavity 140, and the airflow passes through the connecting pipe 170 to the exhaust valve 130 in sequence, and then enters the cooking cavity 140 through the air inlet pipe 160, squeezing out the steam in the cooking cavity 140; at the same time, the exhaust pipe 190 is used to connect the cooking cavity 140 and the exhaust air duct to achieve internal and external air pressure balance, and discharge the steam inside the cooking cavity 140 into the exhaust air duct, condense in the condensation cavity, and the condensed water drips into the condensation water reflux box, and can flow back to the water inlet pipe through the condensation water reflux pipe.

[0069] The exhaust function detection method provided in the embodiment of the present application is described below.

[0070] In the embodiment of the present application, the exhaust function detection method is used for the above-mentioned cooking equipment, mainly to provide timely feedback when the exhaust fan 120 and the exhaust valve 130 fail, reminding the user to perform maintenance to avoid greater losses, ensure the safe use of the cooking equipment 100, and enhance the user experience.

[0071] In the embodiment of the present application, the specific detection method of the exhaust function detection method is not limited. For example, one implementation method is: by detecting the exhaust temperature data outside the cooking cavity 140, it can be determined whether the exhaust valve 130 and the exhaust fan 120 are faulty; another implementation method is: by detecting the status data inside the cooking cavity 140, it can be determined whether the exhaust valve 130 and the exhaust fan 120 are faulty; another implementation method is: by simultaneously detecting the exhaust temperature data outside the cooking cavity 140 and the status data inside the cooking cavity 140, it can be determined whether the exhaust valve 130 and the exhaust fan 120 are faulty.

[0072] It should be noted that the exhaust function detection method in this embodiment includes but is not limited to the above three implementation methods. As long as it can be used to determine whether the exhaust valve 130 and the exhaust fan 120 are faulty, they belong to the protection scope of this application.

[0073] The following is a detailed description of the three detection methods provided in the implementation of this application.

[0074] Embodiment 1: By detecting the exhaust temperature data outside the cooking cavity 140, it is determined whether the exhaust valve 130 and the exhaust fan 120 are faulty.

[0075] Specifically, in this embodiment, the cooking device 100 may further include a first detection unit 181 and a controller, wherein the first detection unit 181 is used to detect temperature data outside the cooking cavity 140, and the controller is used to execute the method of this embodiment.

[0076] In this embodiment, the type of the first detection unit 181 is not limited. For example, the first detection unit 181 in this embodiment can be a temperature sensor. Among them, the temperature sensor is a method of measuring temperature based on the change of physical properties. Common temperature sensors generally include thermistors, thermocouples, thermal resistors, and surface vibration temperature sensors. This embodiment does not limit this.

[0077] In this embodiment, there is no limitation on the location of the first detection unit 181. Figure 1 As shown, the first detection unit 181 is mainly set in the connecting pipe 170 (i.e., the reducer) as an example for explanation. It should be noted that if the first detection unit 181 is set in the air inlet pipe 160, the steam entering the outside of the inner tank will first reach the first detection unit 181, and will not reach the exhaust valve 130, so it is impossible to detect whether the exhaust valve 130 is faulty.

[0078] Therefore, by limiting the first detection unit 181 to be disposed between the exhaust fan 120 and the exhaust valve 130, when the exhaust valve 130 is normally closed, the steam will not contact the first detection unit 181, which is in communication with the air at the inlet of the exhaust fan 120. When the exhaust valve 130 fails, the exhaust valve 130 leaks, and the steam entering the outside of the inner tank will contact the first detection unit 181, so that the exhaust temperature data recorded by the first detection unit 181 can be used to determine whether the exhaust valve 130 is faulty.

[0079] In order to promptly remind the user when the exhaust valve 130 fails, in the embodiment of the present application, Figure 1 and Figure 2 As shown, the cooking device 100 may further include a control panel 150 , and when determining that the exhaust valve 130 is leaking, the control panel 150 may also include: reporting fault prompt information.

[0080] For example, a gas leak alarm device may be provided on the control panel 150. When the exhaust temperature data of the steam outside the inner tank exceeds a set value, the alarm will be triggered and an alarm signal will be issued to remind the user to take emergency measures; at the same time, an alarm sound and a warning light may be triggered to remind the user. This embodiment is not limited to this.

[0081] Reference Figure 3 As shown, the detection steps of the exhaust function detection method provided in this embodiment are as follows:

[0082] Step S01: operating the cooking device, closing the exhaust valve and obtaining exhaust steam temperature data on the inlet side of the exhaust valve;

[0083] Step S02: judging whether the exhaust valve is faulty based on the exhaust temperature data, and controlling the exhaust fan according to the judgment result.

[0084] It should be noted that in step S01 , the exhaust valve 130 needs to be closed when the cooking device 100 is running because the cooking device 100 starts working to heat the food in the cooking cavity 140 . At this time, there is no need to blow air into the cooking cavity 140 .

[0085] In the embodiment of the present application, the exhaust temperature data of the inlet side of the exhaust valve 130 is obtained, which helps to ensure that the steam entering the outside of the inner tank passes through the exhaust valve 130, which is conducive to improving the detection accuracy. In this embodiment, the exhaust temperature data is mainly obtained by the first detection unit 181.

[0086] In the present application, refer to Figure 4 As shown, step S02 may include the following steps:

[0087] Step S021: determining whether the exhaust steam temperature data exceeds a first preset value;

[0088] Step S022: If the value exceeds the first preset value, it is determined that the exhaust valve is leaking, the cooking device is stopped, and the exhaust fan is started;

[0089] Step S023: If the value does not exceed the first preset value, it is determined that the steam exhaust valve is normal and the cooking device continues to operate.

[0090] In the embodiment of the present application, the first preset value is not further limited and can be set according to actual conditions. For example, the first preset value can be the starting temperature TP0.

[0091] In the embodiment of the present application, the exhaust temperature data is not limited. Exemplarily, the exhaust temperature data may be a temperature value, so that when judging whether the exhaust temperature data exceeds a first preset value, it is possible to judge whether the temperature value exceeds the first preset temperature value. Exemplarily, the exhaust temperature data may be a temperature change slope, so that when judging whether the exhaust temperature data exceeds a first preset value, it is possible to judge whether the temperature change slope exceeds the first preset slope value.

[0092] For example, if there is steam leakage in the exhaust valve 130 , the temperature value will rise rapidly, or the temperature change slope will suddenly change, which is significantly different from the normal state, and a judgment can be made based on this.

[0093] It should be noted that in step S022, it is determined that the exhaust valve 130 is leaking, and stopping the cooking device 100 specifically means: stopping the heating module of the cooking device 100, that is, stopping the continued heating of the inside of the cooking cavity 140; the reason for starting the exhaust fan 120 is: there is steam outside the inner pot, even if the cooking device 100 is stopped, the steam will diffuse outside the inner pot, the steam condenses in the electrical space and produces condensed water, causing damage to the electrical components. Therefore, turning on the exhaust fan 120 can discharge the steam leaked to the outside of the inner pot into the cooking cavity 140 in time.

[0094] In an embodiment of the present application, after starting the exhaust fan 120, it may also include: the exhaust fan 120 is shut down after running for a first preset time; or, determining whether the exhaust temperature data is lower than a second preset value, and if the exhaust temperature data is lower than the second preset value, shutting down the exhaust fan 120.

[0095] The exhaust fan 120 is turned off after running for a first preset time, wherein the first preset time can be set according to actual conditions. For example, if the exhaust temperature data of the steam leaking to the outside of the inner tank is too high, the first preset time can be set longer. This embodiment does not limit this.

[0096] The second preset value can be set according to the actual situation, so that when the exhaust temperature data is lower than the second preset value, it can be determined that the leaked steam has been exhausted. This embodiment does not limit this.

[0097] The detailed steps of the exhaust function detection method provided in this embodiment are:

[0098] The cooking device 100 is operated, the exhaust valve 130 is closed, and the first detection unit 181 records the exhaust temperature data of the inlet side of the exhaust valve 130 in real time, such as TP1, and the controller determines whether TP1 exceeds the first preset value. If it exceeds, it is determined that the exhaust valve 130 is leaking, the cooking device 100 is stopped, and the exhaust fan 120 is started, and a fault prompt message is reported on the panel; if it does not exceed, it is determined that the exhaust valve 130 is normal, and the cooking device 100 continues to operate and monitor continuously.

[0099] Therefore, in this embodiment, the exhaust temperature data outside the cooking cavity 140 is detected by the first detection unit 181 to determine whether the exhaust valve 130 is faulty, and the detection accuracy is relatively high.

[0100] Embodiment 2: By detecting the status data inside the cooking cavity 140, it is determined whether the exhaust valve 130 and the exhaust fan 120 are faulty.

[0101] Specifically, in this embodiment, refer to Figure 2 As shown, the cooking device 100 may further include a second detection unit 182 and a controller. The second detection unit 182 is disposed in the cooking cavity 140. The second detection unit 182 is used to detect status data inside the cooking cavity 140. The controller is used to execute the method of this embodiment.

[0102] In this embodiment, the type of the second detection unit 182 is not limited. Exemplarily, the second detection unit 182 may include at least one of a temperature sensor and a humidity sensor.

[0103] For example, when the second detection unit 182 is a temperature sensor, the temperature inside the cooking cavity 140 is detected and judged against the threshold; when the second detection unit 182 is a humidity sensor, the humidity inside the cooking cavity 140 is detected and judged against the threshold; when the second detection unit 182 includes a humidity sensor and a humidity sensor, a combination of humidity and temperature is used to determine against the threshold. Thus, fault reminders are given in the above manner to improve detection accuracy.

[0104] It is understandable that the reason for using a humidity sensor for judgment is: during the normal exhaust process, since the air coming in from the outside is lower than the humidity of the steam inside the cooking cavity 140, during the exhaust process, as the steam content decreases, the humidity inside the cooking cavity 140 will also decrease accordingly. Therefore, it can be used to judge the exhaust effect of the cooking cavity 140.

[0105] Reference Figure 5 As shown, the detection steps of the exhaust function detection method provided in this embodiment are as follows:

[0106] Step S11: After cooking is finished, stop the cooking equipment, open the exhaust valve, and start the exhaust fan;

[0107] Step S12: Acquire status data in the cooking cavity; wherein the status data includes at least one of cavity temperature data and cavity humidity data;

[0108] Step S13: Determine whether the exhaust valve and the exhaust fan are faulty based on the status data.

[0109] It should be noted that the difference between the second embodiment and the first embodiment is that the detection premise of the first embodiment is that the cooking device 100 is in operation and the exhaust valve 130 is in a closed state; the detection premise of the second embodiment is that the cooking device 100 is in an operation end state, the exhaust valve 130 is in an open state, and the exhaust fan 120 is in a start state. In addition, the first embodiment detects the exhaust temperature data outside the cooking cavity 140, and the exhaust temperature data can be a temperature value or a temperature change slope; the second embodiment detects the state data inside the cooking cavity 140, and the state data can be temperature data or humidity data.

[0110] In the present application, refer to Figure 6 As shown, step S13 may include the following steps:

[0111] S131: Determine whether the status data is lower than a third preset value;

[0112] S132: If it is lower than the third preset value, it is determined that the exhaust valve and the exhaust fan are normal;

[0113] S133: If it is not lower than the third preset value, it is determined that the exhaust valve and the exhaust fan are faulty.

[0114] In the embodiment of the present application, the third preset value is not further limited and can be set according to actual conditions. For example, the third preset value can be the starting temperature TQ0.

[0115] The detailed steps of the exhaust function detection method provided in this embodiment are:

[0116] After cooking is finished, the cooking device 100 is stopped, the exhaust valve 130 is opened, and the exhaust fan 120 is started. The second detection unit 182 records the status data in the cooking cavity 140, such as TQ1, in real time. The controller determines whether the status data is lower than a third preset value. If so, the exhaust valve 130 and the exhaust fan 120 are determined to be normal and the detection is continued; if not, the exhaust valve 130 and the exhaust fan 120 are determined to be faulty, and a fault prompt message is reported on the panel.

[0117] It can be understood that if the temperature is lower than the third preset value, it can be determined that the exhaust valve 130 and the exhaust fan 120 are normal. In this way, the steam temperature inside the cooking cavity 140 has dropped to normal, thereby reducing the presence of large steam when the door is opened, thereby minimizing scalding of users, avoiding safety issues, improving the safety performance of the cooking device 100, and enhancing user experience.

[0118] Therefore, in this embodiment, the second detection unit 182 detects the status data in the cooking cavity 140 to determine whether the exhaust valve 130 and the exhaust fan 120 are faulty, and the detection accuracy is relatively high.

[0119] Embodiment 3: Simultaneously detect the exhaust temperature data outside the cooking cavity 140 and the status data inside the cooking cavity 140 to determine whether the exhaust valve 130 and the exhaust fan 120 are faulty.

[0120] Specifically, in this embodiment, the cooking device 100 includes a first detection unit 181, a second detection unit 182 and a controller. The first detection unit 181 is used to detect temperature data outside the cooking cavity 140, the second detection unit 182 is used to detect status data inside the cooking cavity 140, and the controller is used to execute the method of this embodiment.

[0121] It should be noted that the first detection unit 181 in this embodiment is the same component as the first detection unit 181 in the first embodiment, and the second detection unit 182 in this embodiment is the same component as the second detection unit 182 in the second embodiment. This embodiment will not be described in detail.

[0122] Reference Figure 7 As shown, the detection steps of the exhaust function detection method provided in this embodiment are as follows:

[0123] Step S21: After cooking is finished, stop the cooking equipment, open the exhaust valve, and start the exhaust fan;

[0124] Step S22: Acquire status data in the cooking cavity; wherein the status data includes at least one of cavity temperature data and cavity humidity data;

[0125] Step S23: Determine whether the exhaust valve and the exhaust fan are faulty based on the status data and the exhaust temperature data.

[0126] In the present application, refer to Figure 8 As shown, step S23 may include the following steps:

[0127] Step S231: determining whether the exhaust temperature data exceeds a first preset value, and whether the state data is lower than a third preset value;

[0128] Step S232: if the exhaust temperature data does not exceed the first preset value, and the state data is lower than the third preset value, it is determined that the exhaust valve and the exhaust fan are normal;

[0129] Step S233: if the exhaust temperature data does not exceed the first preset value, and the state data is not lower than the third preset value, it is determined that the exhaust valve is not open;

[0130] Step S234: if the exhaust temperature data exceeds the first preset value, and the state data is lower than the third preset value, it is determined that the exhaust valve is leaking;

[0131] Step S235: If the exhaust temperature data exceeds the first preset value and the status data is not lower than the third preset value, it is determined that the exhaust valve is open and the exhaust fan is not started.

[0132] In an embodiment of the present application, in step S231, the first preset value may be the starting temperature TP0, and the method for determining whether the exhaust temperature data exceeds the first preset value is the same as that in Embodiment 1, and will not be repeated in this embodiment; the third preset value may be the starting temperature TQ0, and the method for determining whether the status data is lower than the third preset value is the same as that in Embodiment 2, and will not be repeated in this embodiment.

[0133] In the embodiment of the present application, in step S232, if the exhaust temperature data does not exceed the first preset value, and the state data is lower than the third preset value, that is, the steam temperature outside the cooking cavity 140 and the steam temperature inside the cooking cavity 140 are both within the normal range, and the exhaust valve 130 and the exhaust fan 120 are both normal.

[0134] In the embodiment of the present application, in step S233, if the exhaust temperature data does not exceed the first preset value, and the state data is not lower than the third preset value, that is, the steam temperature inside the cooking cavity 140 is too high, and the steam temperature outside the cooking cavity 140 is normal, that is, the exhaust valve 130 is not opened.

[0135] In the embodiment of the present application, in step S234, if the exhaust temperature data exceeds the first preset value and the state data is lower than the third preset value, that is, the steam temperature outside the cooking cavity 140 is too high and the steam temperature inside the cooking cavity 140 is normal, that is, the exhaust valve 130 is leaking.

[0136] In the embodiment of the present application, in step S235, if the exhaust temperature data exceeds the first preset value, and the state data is not lower than the third preset value, that is, the steam temperature inside the cooking cavity 140 has not dropped, and the steam temperature outside the cooking cavity 140 has increased. That is, the exhaust valve 130 is open, and the exhaust fan 120 is not started.

[0137] Therefore, in this embodiment, by jointly judging the exhaust temperature data detected by the first detection unit 181 and the status data detected by the second detection unit 182 and reporting fault prompt information on the control panel 150 accordingly, the detection accuracy can be improved.

[0138] The embodiment of the present application provides a method for detecting a steam exhaust function and a cooking device. The method for detecting a steam exhaust function includes: running the cooking device, closing the steam exhaust valve and obtaining the exhaust temperature data on the inlet side of the exhaust valve; judging whether the exhaust valve is faulty based on the exhaust temperature data, and controlling the exhaust fan according to the judgment result. In this way, the present application can judge whether the exhaust structure has failed by detecting the temperature, and provide timely feedback when the exhaust structure has failed, reminding the user to perform maintenance, preventing steam from entering the electrical space outside the inner pot and condensing to produce condensed water, causing damage to electrical components, helping to avoid greater losses, ensuring the safe use of the cooking device, and improving the user experience.
