Description

Technical Field

[0001] The present invention relates to the field of household appliances, and particularly to a smoke range linkage system, a control method thereof, and a computer-readable storage medium. Background Art

[0002] Existing range hoods and gas stoves can achieve smoke range linkage, which can provide convenience for users.

[0003] Some existing gas stoves can automatically turn off the fire and emit a beeping sound to remind when a fault occurs. However, when there is smoke range linkage, the noise of the range hood is often too loud while the fault warning sound of the gas stove is too small, and users cannot timely know the fault situation, so there are potential safety hazards. Summary of the Invention

[0004] The first object of the present invention is to provide a control method for a smoke range linkage system that ensures users can timely discover the sound reminder of the stove fault.

[0005] The second object of the present invention is to provide a smoke range linkage system that ensures users can timely discover the sound reminder of the stove fault.

[0006] The third object of the present invention is to provide a computer-readable storage medium that can implement the control method of the above-mentioned smoke range linkage system.

[0007] The control method for the smoke range linkage system provided by the first object of the present invention includes controlling the operation of the range hood; if it is confirmed that the stove is in a fault state, sending a sound reminder signal, and controlling the fan of the range hood to decelerate or stop during the duration of the sound reminder signal.

[0008] As can be seen from the above solution, the main influencing factor that hinders users from receiving the stove fault reminder sound is the noise generated by the fan inside the range hood when it is working. Therefore, based on the linkable characteristics of the smoke range linkage system, when the stove is in a fault state, not only a sound reminder signal is sent, but also the range hood decelerates or stops during the duration of the sound reminder signal. Therefore, it can ensure that the reminder sound signal can be conveyed to the user in the first time and ensure safety.

[0009] A further solution is that in the step of sending a sound reminder signal and controlling the fan of the range hood to decelerate or stop during the duration of the sound reminder signal if it is confirmed that the stove is in a fault state, it includes: if it is confirmed that the stove is in the first fault state, sending a sound reminder signal and controlling the fan of the range hood to decelerate during the duration of the sound reminder signal; if it is confirmed that the stove is in the second fault state, sending a sound reminder signal and controlling the fan of the range hood to stop during the duration of the sound reminder signal; the first fault state is a state where there is a faulty stove top and a working stove top; the second fault state is a state where there is a faulty stove top and the rest of the stove tops are all non-working stove tops.

[0010] As can be seen from the above, for the case where the cooking appliance fails, the control method of the present invention also combines the usage scenarios of the cooking appliance and adjusts the operation of the range hood in different ways. For example, when one cooking hob fails while the other is in use, the range hood needs to work in this scenario, and there is a need for fume extraction at this time, so the range hood is controlled to operate at a reduced speed; for another example, when one cooking hob fails but no other cooking hobs are working, there is no need for fume extraction, so the range hood is controlled to stop directly. With this setting, the functional rationality can be ensured in combination with the usage scenario, and a better power-saving effect can be achieved.

[0011] A further solution is that if it is confirmed that the cooking appliance is in the first failure state, the range hood is controlled to reduce its speed to the lowest speed gear.

[0012] As can be seen from the above, further, even if other cooking hobs are working, in order to ensure that the sound reminder signal can be conveyed to the user in the first time as much as possible, preferably, the speed of the range hood is adjusted down to the lowest.

[0013] A further solution is that in the step of sending a sound reminder signal and controlling the fan of the range hood to reduce its speed or stop during the duration of the sound reminder signal if it is confirmed that the cooking appliance is in a failure state, it includes that if it is confirmed that there is a faulty cooking hob and the power of the cooking appliance is lower than a preset value, it is confirmed that the cooking appliance is in a low-power failure state; if it is confirmed that the cooking appliance is in a low-power failure state, a sound reminder signal is sent and the fan of the range hood is controlled to stop during the duration of the sound reminder signal.

[0014] As can be seen from the above, since the failure of the cooking appliance may be an automatic shutdown caused by the low battery power of the cooking appliance, the system confirms this situation as a low-power failure state. Since all the functions of the cooking appliance are turned off under low power, there is no need for fume extraction at this time, so controlling the range hood to stop can ensure that the sound reminder signal is conveyed to the user to the greatest extent.

[0015] A further solution is that the cooking appliance is provided with a first sound sending module, and the range hood is provided with a second sound sending module; in the step of sending a sound reminder signal if it is confirmed that the cooking appliance is in a failure state, it includes that if it is confirmed that the cooking appliance is in a low-power failure state, a sound reminder signal is sent through the first sound sending module and the second sound sending module; or, if it is confirmed that the cooking appliance is in a low-power failure state, a sound reminder signal is sent only through the second sound sending module.

[0016] A further solution is that in the step of sending a sound reminder signal through the first sound sending module and the second sound sending module if it is confirmed that the cooking appliance is in a low-power failure state, it includes that if it is confirmed that the cooking appliance is in a low-power failure state, a first sound reminder signal is first sent by the first sound sending module and maintained for a preset duration, and then a second sound reminder signal is sent by the second sound sending module.

[0017] As can be seen from the above, when the battery of the cooking appliance has sufficient power, the sound reminder signal is generally emitted by the cooking appliance. However, when the battery of the cooking appliance has low power and is insufficient to maintain the operation of the first sound transmission module for a long time, and the range hood is powered by mains electricity, therefore, based on the linkage characteristics of the cooking appliance and range hood linkage system, combining the first sound transmission module of the cooking appliance and the second sound transmission module of the range hood can ensure the continuity of the sound reminder signal.

[0018] A further solution is that the sound frequency of the second sound reminder signal is the same as that of the first sound reminder signal.

[0019] As can be seen from the above, preferably, as a continuation of the first sound reminder signal, on the premise that the user usually knows that the first sound reminder signal is a fault reminder, if the sound frequency of the second sound reminder signal is the same as that of the first sound reminder signal, it can cause a better auditory response, which is more conducive to the user to identify and detect the situation.

[0020] Another further solution is that in the step of confirming that the cooking appliance is in a fault state, it includes first judging whether the cooking appliance is in a low-power fault state. If not, execute the confirmation steps for other fault states other than the low-power fault state of the cooking appliance.

[0021] As can be seen from the above, too low battery power may cause the gas stove to fail to complete the timed turn-off normally and cannot continuously emit sound reminders. Therefore, the low-power state should be judged first. If the judgment result is yes, execute the early automatic turn-off and transfer the emission of sound and information reminders to the range hood.

[0022] The range hood and cooking appliance linkage system provided by the second object of the present invention includes a processor, and the processor is used to implement the control method of the above-mentioned range hood and cooking appliance linkage system when executing the computer program stored in the memory.

[0023] The computer-readable storage medium provided by the third object of the present invention stores a computer program, and the computer program implements the control method of the above-mentioned range hood and cooking appliance linkage system when executed by a processor.

[0027] Embodiment of the range hood and cooking appliance linkage system

[0028] See Figure 1 and Figure 2 As shown in Figure 1 and Figure 2 , the smoke range interlock system of the present invention is composed of a gas stove 1 and a range hood 2. The gas stove 1 is the stove of the present invention. The gas stove 1 includes a first cooking surface 101 and a second cooking surface 102. A first digital tube 14 serving as a display module is arranged on the surface of the gas stove 1, and a second digital tube 24 serving as a display module is arranged on the front side of the range hood 2.

[0029] The gas stove 1 includes a first controller 11, a first electromagnetic valve 121, a second electromagnetic valve 122, a first buzzer 13, the above-mentioned first digital tube 14, and a radio frequency transmitting module 15. The electromagnetic valve 12, the first buzzer 13, the above-mentioned first digital tube 14, and the radio frequency transmitting module 15 are all electrically connected to the first controller 11. The range hood 2 includes a second controller 21, a blower 22, a second buzzer 23, the above-mentioned second digital tube 24, and a radio frequency receiving module 25. The blower 22, the second buzzer 23, the above-mentioned second digital tube 24, and the radio frequency receiving module 25 are all electrically connected to the second controller 21. Communication can be achieved between the gas stove 1 and the range hood 2 through the radio frequency transmitting module 15 and the radio frequency receiving module 25. Among them, the first buzzer 13 and the second buzzer 23 are respectively the first sound sending module and the second sound sending module of the present invention.

[0030] The first controller 11 controls the first electromagnetic valve 121 and the second electromagnetic valve 122 to achieve automatic shutdown of the first cooking surface 101 and the second cooking surface 102. When the system determines that a fault occurs in the first cooking surface 101 and the second cooking surface 102, a first sound reminder signal can be emitted through the first buzzer 13 and a fault code can be displayed through the first digital tube 14. Since the gas stove 1 and the range hood 2 can communicate, when the system determines that a fault occurs in the first cooking surface 101 and the second cooking surface 102, a second sound reminder signal can also be emitted through the second buzzer 23 and a fault code can be displayed through the second digital tube 24. The fault code is the reminder information of the present invention. Among them, preferably, the sound frequency of the second sound reminder signal emitted by the second buzzer 23 is the same as the sound frequency of the first sound reminder signal emitted by the first buzzer 13. In addition, in the range hood 2, the start and stop of the blower 22 and the speed regulation of the blower 22 can be controlled through the control signal of the second controller 21.

[0031] Embodiment of the control method of the smoke range interlock system

[0032] The control method of the present invention is based on a stove with an automatic shutdown function and combines the actual use situation to solve the problem that the noise generated by the range hood hinders the user from receiving the sound reminder signal of the stove fault. The first processor 11 is used to implement the control method of the above-mentioned smoke range interlock system when executing the computer program stored in the memory.

[0033] The control method of the smoke range interlock system includes:

[0034] Combined with Figures 1 to 3 , first, the system will perform step S1. The first controller 11 confirms the stove failure through the corresponding signal. For example, it confirms the failure of the first stove top 101. Subsequently, step S2 is executed, and the corresponding failure code of the first stove top 101 is displayed on the first digital tube 14.

[0035] Subsequently, the system executes step S3 to determine whether the battery of the gas stove 1 has a low power. For example, the system performs real-time detection of the battery power of the gas stove 1, and the system can use the real-time detection data as the basis for the judgment in step S3. If the judgment result is yes, step S8 is executed to confirm that the current is in the low-power failure state and perform corresponding control; if the judgment result is no, step S4 is executed. First, the faulty stove top is turned off, that is, the first stove top 101 in the above example, and then step S5 is continued to determine whether other stove tops other than the faulty stove top are working. For example, after confirming that the first stove top 101 is the faulty stove top, it is necessary to determine whether the second stove top 102 is working in step S5.

[0036] If the judgment step of step S5 is yes, step S6 is executed to confirm that the current is in the first failure state and perform corresponding control; if the judgment step of step S5 is no, step S7 is executed to confirm that the current is in the second failure state and perform corresponding control.

[0037] It can be seen that after confirming the failure of the gas stove 1, the system will further determine which state among the low-power failure state, the first failure state, and the second failure state it is in, and according to the judgment result, control the gas stove 1 and the range hood 2 in different ways. Among them, it can be seen that the system first determines whether the stove is in the low-power failure state. If not, it executes the confirmation step for other failure states other than the low-power failure state of the stove. In this embodiment, other failure states other than the failure state refer to the first failure state and the second failure state.

[0038] The reason is that confirming the failure state requires sending out a sound reminder signal and displaying the failure code and lasting for a certain period of time. If the battery power of the gas stove is insufficient, it not only cannot normally complete the timed shutdown of the fire, but may not be sufficient to support the first buzzer 13 and the first digital tube 14 to last for a sufficient period of time. Therefore, it is necessary to report the failure of the gas stove 1 through the range hood 2 based on the range hood and stove linkage system.

[0039] Therefore, in this embodiment, in steps S3 and S8, when the battery voltage in the gas stove 1 is lower than 60%, the system confirms that the current is in a low battery power failure state. At this time, the corresponding control for the low battery power failure state includes: turning off all stove tops, that is, turning off the faulty first stove top 101 and the non-faulty second stove top 102. The purpose is to automatically turn off the fire in advance to remind the user that the stove has been turned off. In addition, the corresponding control also includes controlling the blower 22 to stop, controlling the first buzzer 13 to emit a first sound reminder signal for a short duration, and controlling the first digital tube 14 to display the fault code and the low battery power information for a short duration, and then controlling the second buzzer 23 to emit a second sound reminder signal at the same sound frequency as the first sound reminder signal and controlling the second digital tube 24 to display the fault code of the gas stove as a continuous reminder. This setting can ensure that the gas stove 1 can be turned off in time to ensure safety, and can also ensure that the fault reminder information can last for a sufficient duration. Of course, more importantly, controlling the blower 22 to stop ensures that the first sound reminder signal and the second sound reminder signal can be effectively conveyed to the user in the first place, and in the current situation, there is no working stove top and no need for fume extraction, so directly turning off the blower 22 is more power-saving.

[0040] When the judgment result of step S3 is negative, that is, it means that the battery power of the current gas stove 1 is sufficient to support the continuous operation of the first buzzer 13 and the first digital tube 14 for a long time. Therefore, in steps S6 and S7, whether the first fault state or the first fault state is confirmed, in the corresponding control of both, the first buzzer 13 and the first digital tube 14 on the gas stove 1 are used to emit the fault reminder signal.

[0041] When the judgment result of step S3 is negative, first execute step S4 to turn off the faulty first stove top 101 and display the fault code on the first digital tube 14. Subsequently, the system also distinguishes the first fault state and the second fault state according to two different actual usage scenarios and further selects different corresponding control methods. The main difference between the above different corresponding control methods lies in the difference in the way of controlling the blower 22. Further, it is to choose to control the blower 22 to stop or choose to control the blower 22 to reduce speed.

[0042] Further, continuing with the above example, when the first cooking range 101 is confirmed as a faulty cooking range, the above two different actual usage scenarios are as follows: 1. The second cooking range 102 is in the process of firing up and working; 2. The second cooking range 102 is in a non-working state. When the second cooking range 102 is in the process of firing up and working, there is a need for fume extraction and the blower 22 should not be controlled to stop. On the contrary, when the second cooking range 102 is in a non-working state, there is no need for fume extraction, and directly controlling the blower 22 to stop is more conducive for the user to clearly hear the sound reminder signal and is more power-saving. For this reason, step S5 is used to determine which of the above two actual usage scenarios the current situation belongs to. If the judgment result of step S5 is yes, that is, the current second cooking range 102 is in the process of firing up and working, it is confirmed that the current is in the first fault state, the first buzzer 13 sounds and continues for a preset duration, and during the continuous time when the first buzzer 13 sounds, the blower 22 is controlled to reduce its speed to the lowest speed gear. When the sound of the first buzzer 13 stops, the blower 22 speeds up and resumes its original speed gear.

[0043] If the judgment result of step S5 is no, that is, the current second cooking range 102 is in a non-working state, it is confirmed that the current is in the second fault state, the blower 22 is directly controlled to stop, and the first buzzer 13 sounds and continues for a preset duration.

[0044] Therefore, the control method of the present invention is based on the linkage between the range hood and the cooking range. After confirming that the cooking range is in a fault state, the blower 22 of the range hood 2 is controlled to reduce its speed or stop to reduce noise, ensuring that the sound reminder signal is conveyed to the user in the first instance. Moreover, the control logic is refined according to several different actual situations to ensure the continuous effectiveness of the sound reminder signal and the display of the fault information, minimizing the impact on the normal operation of the range hood 2 during the fault reporting process and being more power-saving.

[0045] Finally, it should be emphasized that the above description is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0046] In other embodiments, if it is confirmed that the cooking range is in a low battery fault state, only the second buzzer and the second digital tube of the range hood are used to report the fault in the corresponding control.

[0047] In other embodiments, regardless of whether the cooking range is in a low battery fault state, only the second buzzer and the second digital tube of the range hood are used to report the fault.

When the processor of the computer device reads and executes the computer program stored in the memory, the steps of the control method of the above-mentioned smoke range linkage system can be implemented.
