[0026] In order to make the technical solutions in the specific embodiments or prior art of the present application clearer, the drawings needed in the specific embodiments or prior art description will be briefly introduced as follows. Obviously, the drawings in the following description are some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative effort on the basis of these drawings.

[0027] At present, most of the existing double-cavity integrated stoves are simply one cavity to realize one function, for example: one cavity of the double-cavity integrated stove realizes the function of an electric steamer, and the other cavity of the double-cavity integrated stove realizes the function of an electric oven. However, the function realized by each cavity of the existing double-cavity integrated stove is relatively single, which cannot meet the diverse needs of users and the faster cooking needs and better cooking effect. In addition, the existing double-cavity integrated stove lacks safety protection measures, which may cause safety hazards caused by the pressure in the cavity exceeding the safety threshold or the failure of the steam valve, thereby reducing the user experience.

[0028] Based on this, the embodiment of the present application provides a control method and device of an integrated stove external steam system, and specifically provides a control logic of a double-cavity integrated stove external steam system. If the pressure data of the cavity is greater than a first pressure threshold or the state of the steam valve is a failure state, the cavity stops working; if the pressure data of the steam generator is greater than a second pressure threshold, the water vapor is discharged into the range hood. The safety hazards caused by the pressure in the cavity exceeding the safety threshold or the failure of the steam valve can be prevented, and the user experience is improved.

[0029] To facilitate the understanding of the present embodiment, first, a control method of an integrated stove external steam system disclosed by the present embodiment is introduced in detail.

[0030] Embodiment one:

[0031] The embodiment of the present application provides a control method of an integrated stove external steam system, and the integrated stove includes multiple cavities and a range hood, and the steam system includes a steam generator and multiple steam valves.

[0032] Referring to the flow chart of the control method of the integrated stove external steam system shown in Figure 1 The control method of the integrated stove external steam system includes the following steps:

[0033] In step S102, it is determined that the multiple cavities are in a steam function working state, and the pressure data of the multiple cavities, the pressure data of the steam generator and / or the state of the multiple steam valves are obtained.

[0034] The steam system in the present embodiment can be located above the top of the steam baking module and the rear of the steam baking module. The steam system can include multiple cavities and a steam generator. Taking two cavities as an example, two cavities can share one steam generator, and by combining the opening and closing of the steam valve, each cavity can independently run the steam function, and each cavity can also run the steam function at the same time, and the synchronous running of the steam baking function and the steam function of each cavity is also met.

[0035] In the present embodiment, the steam functions of the multiple cavities can be controlled to work at the same time. Taking two cavities as an example, the steam functions of the two cavities can be controlled to run at the same time, that is, the cavities are in a steam function working state.

[0036] After the steam functions of the multiple cavities work at the same time, the present embodiment can monitor the pressure data of the cavities, the pressure data of the steam generator and / or the state of the multiple steam valves. The state of the steam valve can include an effective state and a failure state, and the pressure data of the cavities and the pressure data of the steam generator can be represented by specific numerical values.

[0037] If the pressure data of at least one cavity is greater than a preset first pressure threshold or the state of at least one steam valve is a failure state, the plurality of cavities stop working.

[0038] In order to prevent safety hazards, the first pressure threshold can be preset in the embodiment, if the pressure data of at least one cavity is greater than the first pressure threshold, it means that safety hazards may occur, at this time, the plurality of cavities can be controlled to stop working. In addition, if the state of at least one steam valve is a failure state, it also means that safety hazards may occur, at this time, the plurality of cavities can also be controlled to stop working.

[0039] Taking two cavities as an example, the pressure data of cavity 1 is a and greater than the first pressure threshold x, at this time, the two cavities can be controlled to stop working; or, the state of steam valve 1 is a failure state, at this time, the two cavities can also be controlled to stop working.

[0040] If the pressure data of the steam generator is greater than a preset second pressure threshold, the water vapor is discharged into the range hood.

[0041] In order to prevent safety hazards, the second pressure threshold can also be preset in the embodiment, if the pressure data of at least one steam generator is greater than the second pressure threshold, it means that safety hazards may occur, at this time, the water vapor can be discharged into the range hood, so as to reduce the pressure data of the steam generator.

[0042] The embodiment of the present application provides a control method of an integrated stove external steam system, determines that the plurality of cavities are in a steam function working state, acquires pressure data of the plurality of cavities, pressure data of the steam generator and / or states of the plurality of steam valves; if the pressure data of at least one cavity is greater than a preset first pressure threshold or the state of at least one steam valve is a failure state, the plurality of cavities stop working; if the pressure data of the steam generator is greater than a preset second pressure threshold, the water vapor is discharged into the range hood. Safety hazards caused by the pressure in the cavity exceeding the safety threshold or the steam valve failure can be prevented, and the use experience of the user is improved.

[0043] Embodiment two:

[0044] The embodiment provides another control method of an integrated stove external steam system, which is realized on the basis of the above-mentioned embodiment, and the flow chart of another control method of an integrated stove external steam system is shown in FIG. 2. Figure 2 The control method of the integrated stove external steam system in the embodiment includes the following steps:

[0045] Step S202, determining that the plurality of cavities are in a steam function working state, acquiring pressure data of the plurality of cavities, pressure data of the steam generator and / or states of the plurality of steam valves.

[0046] In some embodiments, the steam system in the present embodiment further comprises: a water tank assembly, a control board assembly, a micro switch; the present embodiment can insert the water tank assembly filled with water into the control board assembly, so that the top rod at the rear end of the water tank assembly touches the micro switch, and the micro switch sends a first signal to the control board assembly; the control board assembly controls the plurality of cavities to work based on the steam function working state based on the first signal and the user's steam function setting operation for the plurality of cavities.

[0047] In the present embodiment, it can be determined that the plurality of cavities are in the steam function working state first. First, the water tank assembly can be filled with water, and then the water tank assembly is inserted into the corresponding hole of the control board assembly. The top rod at the rear end of the water tank assembly touches the micro switch, and the micro switch can feed back the first signal that the water tank assembly is inserted into the control board assembly to the control board assembly.

[0048] The user can perform the steam function setting operation, taking the left cavity and the right cavity as an example. The user can set the steam function, temperature and time of the left cavity and the right cavity, close the door body, and press the start key. The control board assembly controls the plurality of cavities to work based on the steam function working state based on the first signal and the user's steam function setting operation for the plurality of cavities.

[0049] In some embodiments, the steam system further comprises: a water inlet pump, a water inlet pipeline assembly, and a heating pipe assembly; the water inlet pump draws the water in the water tank assembly into the steam generator through the water inlet pipeline assembly; when the water level of the steam generator reaches a preset first water level threshold, the water inlet pump stops working, and the steam generator and the heating pipe assembly start working; after the water in the steam generator is converted into water vapor, the water vapor enters the plurality of cavities through a plurality of steam valves, so that the plurality of cavities enter the preheating phase of the steam function working state.

[0050] Taking the left cavity and the right cavity as an example, the cavities can first enter the preheating phase after starting to work. The water inlet pump and the cooling fan in the preheating phase start to work, and the right cavity steam valve and the left cavity steam valve are opened. The water inlet pump draws the water in the water tank assembly into the steam generator through the water inlet pipeline assembly through the water pipe. When the water in the steam generator reaches the first water level threshold (i.e. the highest water level), the water inlet pump stops working, and the steam generator and the heating pipe assembly start working. The water inlet pump can be controlled by time to calculate the time required to reach the first water level threshold.

[0051] The heating pipe assembly can include the inner pipe in the right cavity lower heating pipe assembly, the right cavity upper heating pipe assembly, the left cavity upper heating pipe assembly, and the inner pipe of the left cavity lower heating pipe assembly. The right cavity upper heating pipe assembly and the left cavity upper heating pipe assembly cannot work at the same time and need to work alternately.

[0052] After the steam generator and the heating pipe assembly start to work, the embodiment can convert the water in the steam generator into water vapor, and then make the water vapor enter the cavities through the steam valves, so that the cavities all enter the preheating phase of the steaming function working state.

[0053] In some embodiments, the steam system further comprises a three-way steam pipe, a plurality of pressure relief valves, a plurality of air inlet pipes, and a plurality of cavity and inner container assemblies; the embodiment can make the water vapor enter the plurality of pressure relief valves through the three-way steam pipe; the water vapor in the plurality of pressure relief valves enters the plurality of cavities through the plurality of steam valves respectively; and the water vapor in the plurality of cavities enters the plurality of inner container assemblies through the plurality of air inlet pipes.

[0054] Taking two cavities (i.e., left cavity and right cavity) as an example, when the water in the steam generator becomes water vapor, the water vapor enters the pressure relief valve and the left cavity steam valve through the two ends of the three-way steam pipe respectively, then enters the right cavity steam valve through the other end of the pressure relief valve, then enters the right cavity air inlet pipe through the other end of the right cavity steam valve, and finally enters the right cavity inner container assembly, while entering the left cavity air inlet pipe through the other end of the left cavity steam valve, and finally entering the left cavity inner container assembly.

[0055] After entering the preheating phase of the steaming function working state, whether to enter the holding state of the steaming function working state can be determined by detecting the temperature, for example, detecting the temperature data of the plurality of inner container assemblies; when the plurality of temperature data all reach the preset temperature threshold, the steam generator and the heating pipe assembly stop working, so that the plurality of cavities all enter the holding phase of the steaming function working state.

[0056] In some embodiments, the steam system further comprises a plurality of temperature sensors; the plurality of temperature sensors detect the temperature data of the plurality of inner container assemblies; when the plurality of temperature data all reach the preset temperature threshold, the plurality of temperature sensors send a second signal to the control board assembly; and the control board assembly controls the steam generator and the heating pipe assembly to stop working based on the second signal, so that the plurality of cavities all enter the holding phase of the steaming function working state.

[0057] Taking two cavities (i.e., left cavity and right cavity) as an example, when the water vapor is continuously generated, the temperature in the right cavity inner container assembly and the left cavity inner container assembly continuously rises, and the right cavity temperature sensor and the left cavity temperature sensor can respectively monitor the temperature in the right cavity inner container assembly and the left cavity inner container assembly in real time; when the temperature in the right cavity inner container assembly and the left cavity inner container assembly reaches the preset temperature threshold, the right cavity temperature sensor and the left cavity temperature sensor feed back the second signal to the control board assembly, at which time the steam generator, the right cavity upper heating pipe assembly, and the left cavity upper heating pipe assembly stop working and enter the holding phase.

[0058] In some embodiments, the steam generator and the heating pipe assembly work based on the steam amount and temperature data; when the water level of the steam generator reaches the preset second water level threshold, the steam generator and the heating pipe assembly stop working, and the water inlet pump starts working; the water inlet pump draws the water in the water tank assembly into the steam generator through the water inlet pipeline assembly.

[0059] Taking two cavities (i.e., left cavity and right cavity) as an example, the steam generator, the inner pipe in the right cavity lower heating pipe assembly, and the inner pipe in the left cavity lower heating pipe assembly can be regularly turned on according to the steam amount and the temperature in the cavity, for example: the steam generator works for 20s and stops working for 40s in a 60s cycle; the right cavity upper heating pipe assembly and the left cavity upper heating pipe assembly work for 1s-8s and stop working for 59s-52s in a 60s cycle; the inner pipe in the right cavity lower heating pipe assembly and the inner pipe in the left cavity lower heating pipe assembly work for 40s-60s and stop working for 20s-50s in a 60s cycle, and the working time is adjusted according to the condensate water at the bottom of the cavity and the temperature PID (Proportional Integral Derivative) in the cavity, to form a cycle.

[0060] When the water level of the steam generator reaches the preset second water level threshold, it indicates that the water needs to be continuously drawn into the steam generator, the steam generator and the heating pipe assembly stop working, and the water inlet pump starts working; the water inlet pump can draw the water in the water tank assembly into the steam generator through the water inlet pipeline assembly.

[0061] In some embodiments, the steam system further comprises a water level probe assembly; the water level probe assembly sends a third signal to the control board assembly; the control board assembly controls the steam generator and the heating pipe assembly to stop working and controls the water inlet pump to start working based on the third signal.

[0062] As the water in the steam generator is gradually heated into steam, when the water level probe assembly detects that the water in the steam generator decreases to the second water level threshold (i.e., the lowest water level), a third signal is fed back to the control board assembly, the steam generator stops heating, and at the same time, the water inlet pump starts working, draws the water in the water tank assembly into the steam generator through the water inlet pipeline assembly, and works in a cycle.

[0063] In step S204, if the pressure data of at least one cavity is greater than the preset first pressure threshold or the state of at least one steam valve is a failure state, the plurality of cavities stop working.

[0064] Taking two cavities (i.e., left cavity and right cavity) as an example, when the pressure data in the cavity (right cavity inner container assembly and left cavity inner container assembly) exceeds the first pressure threshold or the two steam valves (right cavity steam valve and left cavity steam valve) are invalid, the plurality of cavities stop working.

[0065] Step S206, if the pressure data of the steam generator is greater than the preset second pressure threshold, the water vapor is discharged into the range hood.

[0066] In some embodiments, the steam system further comprises: a pressure relief valve; the water vapor can be discharged into the range hood through the pressure relief valve. When the pressure data of the steam generator exceeds the second pressure threshold, in order to reduce the pressure of the steam pressure generator, the water vapor can be discharged into the range hood through the pressure relief valve.

[0067] Step S208, when the multiple cavities all end work, the water pump draws the water of the steam generator back to the water tank assembly through the back-pumping pipeline assembly.

[0068] In some embodiments, the steam system further comprises: a back-pumping water pump and a back-pumping pipeline assembly; when the multiple cavities all end work, the user can press the power key on the control panel assembly to shut down, and the back-pumping water pump can draw the water of the steam generator and the back-pumping pipeline assembly into the water tank assembly.

[0069] The above method provided by the embodiment of the present application determines that the multiple cavities are all in the steam function working state, acquires the pressure data of the multiple cavities, the pressure data of the steam generator and / or the state of the multiple steam valves; if the pressure data of at least one cavity is greater than the preset first pressure threshold or the state of at least one steam valve is the failure state, the multiple cavities stop working; if the pressure data of the steam generator is greater than the preset second pressure threshold, the water vapor is discharged into the range hood. The safety hidden danger caused by the pressure exceeding the safety threshold in the cavity or the failure of the steam valve can be prevented, and the use experience of the user is improved.
