Description

Technical Field

[0001] The utility model relates to the technical field of kitchen electrical equipment, in particular to a smoke and stove linkage system. Background Art

[0002] The smoke and stove linkage system is an intelligent application technology that integrates the range hood and gas stove, and can achieve synchronous startup and adjustment of the two. The existing smoke and stove linkage system has a one-button stir-fry function. By setting a one-button stir-fry button on the gas stove and changing the gas stove's control system, the stir-fry firepower and high-fire firepower of the gas stove can be controlled.

[0036] The utility model specifically provides an embodiment of a smoke stove linkage system. Figure 1 , including a gas stove control unit, a range hood control unit, a linkage module, at least one ignition micro switch, at least one high-fire micro switch, at least one one-touch stir-fry start button and at least one monostable valve assembly; the ignition micro switch is arranged on the gas stove, and is used to provide an ignition signal identification to the gas stove control unit; the high-fire micro switch is arranged on the gas stove, and is used to provide a high-fire state signal identification to the gas stove control unit; the monostable valve assembly is arranged on the high-fire gas transmission channel of the gas stove, and is controlled by the gas stove control unit to open or close the valve; the one-touch stir-fry start button is arranged on the range hood, and is used to provide user operation and send a one-touch stir-fry start signal or a one-touch stir-fry stop signal to the range hood control unit; the linkage module is used to enable the gas stove control unit and The range hood control units communicate with each other; the gas stove control unit is configured to receive an ignition signal and a high-fire status signal and transmit them to the range hood control unit via a linkage module. It is also configured to receive a one-touch stir-fry start signal or a one-touch stir-fry stop signal from the range hood control unit and control the monostable valve assembly to inhale or open the valve to switch between the high-fire state and the stir-fry power state. The range hood control unit is configured to receive the ignition signal and the high-fire status signal and the one-touch stir-fry start signal or the one-touch stir-fry stop signal from the gas stove control unit, control the range hood to start according to the ignition signal, indicate that the one-touch stir-fry start button is available according to the high-fire status signal, and transmit the one-touch stir-fry start signal or the one-touch stir-fry stop signal to the gas stove control unit via the linkage module. Through the communication between the gas stove control unit, the range hood control unit, the linkage module, the ignition microswitch, and the high-fire microswitch, a user can control the monostable valve assembly to open or inhale by touching the one-touch stir-fry start button on the range hood, thereby quickly turning the stir-fry power of the gas stove on or off. Through the range hood and stove linkage system, a one-touch stir-fry start button can be set on the range hood, avoiding changing the gas stove's control system and also avoiding an increase in the power consumption of the gas stove's control system.

[0037] In this embodiment, the gas stove can be divided into a single-burner gas stove and a double-burner gas stove; when the gas stove is a single-burner gas stove, the smoke stove linkage system includes a gas stove control unit, a range hood control unit, a linkage module, an ignition micro switch, a high-fire micro switch, a one-touch stir-fry start button and a monostable valve assembly. The working process is shown in FIG. Figure 2That is: when the ignition microswitch is closed, the gas stove control unit receives the ignition signal sent by the ignition microswitch, and sends the ignition signal to the range hood control unit through the linkage module. After receiving the ignition signal, the range hood control unit controls the range hood to start and start to absorb oil smoke. At this time, the gas stove is in medium or low heat state, and the range hood control unit prompts that the one-button stir-fry start button is unavailable; when the high-fire microswitch is closed, the gas stove control unit receives the high-fire state signal sent by the high-fire microswitch, and sends the high-fire state signal to the range hood control unit through the linkage module. After receiving the high-fire state signal, the range hood control unit prompts that the one-button stir-fry start button is available. At this time, touch Alternatively, after pressing the stir-fry start button, the range hood control unit sends a stir-fry start signal to the cooker control unit via the linkage module. The cooker control unit then controls the monostable valve assembly to energize, switching the cooker to the stir-fry mode. When the user presses the stir-fry start button again, a stir-fry stop signal is sent to the range hood control unit. The range hood control unit then sends a stir-fry stop signal to the cooker control unit via the linkage module. Upon receiving the stop signal, the cooker control unit controls the monostable valve assembly to open, switching the cooker to the high heat mode. Repeated operation of the stir-fry start button allows for quick switching between the high and low heat modes, making operation very convenient. Furthermore, if the user does not turn off the stir-fry mode within a specified time (e.g., 1 minute, 2 minutes, or 3 minutes) after the stir-fry mode is activated, the cooker control unit automatically controls the monostable valve assembly to open, switching the stir-fry mode to the high heat mode to ensure safety.

[0038] When the gas stove is a double-burner gas stove, the smoke / stove linkage system includes a gas stove control unit, a range hood control unit, a linkage module, two ignition microswitches (divided into a left ignition microswitches and a right ignition microswitches), two high-fire microswitches (divided into a left high-fire microswitches and a right high-fire microswitches), two one-touch stir-fry start buttons (divided into a left one-touch stir-fry start button and a right one-touch stir-fry start button), and two monostable valve assemblies (divided into a left monostable valve assembly and a right monostable valve assembly). When the double-burner gas stove is used on one side, its workflow refers to that of the single-burner gas stove; when the double-burner gas stove is used on both sides at the same time, its workflow refers to that of the Figure 3, that is: when the left ignition microswitch and the right ignition microswitch are closed, the gas stove control unit receives the ignition signal sent by any ignition microswitch, and sends the ignition signal to the range hood control unit through the linkage module. After receiving the ignition signal, the range hood control unit controls the range hood to start and start to absorb oil smoke. At this time, the two burners on the gas stove are in medium or low heat state, and the range hood control unit prompts that the two one-button stir-fry start buttons are unavailable; when the left high-fire microswitch is closed or the right high-fire microswitch is closed, the gas stove control unit receives the high-fire state signal sent by the left high-fire microswitch or the right high-fire microswitch, and sends the high-fire state signal to the range hood control unit through the linkage module. After receiving the high-fire state signal, the range hood control unit prompts that the left one-button stir-fry start button or the right one-button stir-fry start button is available. At this time, touch Or after pressing the left one-button stir-fry start button or the right one-button stir-fry start button, the range hood control unit sends a one-button stir-fry start signal to the stove control unit through the linkage module, and then the stove control unit controls the monostable valve assembly on the corresponding side to suck the valve, thereby switching the firepower of the burner on the corresponding side to the stir-fry firepower state. When the user operates the one-button stir-fry start button on that side again, it sends a one-button stir-fry shutdown signal to the range hood control unit, and then the range hood control unit again sends a one-button stir-fry shutdown signal to the stove control unit through the linkage module. After receiving the one-button stir-fry shutdown signal, the stove control unit controls the monostable valve assembly on the corresponding side to open the valve, thereby switching the firepower of the burner on the corresponding side to the high fire state. By the user repeatedly operating the one-button stir-fry start button on either side, the firepower on the corresponding side can be quickly switched between the high fire state and the stir-fry firepower state, which is very convenient to operate. Similar to a single-burner gas stove, after the stir-fry mode is turned on, if the user does not turn off the stir-fry mode within a certain period of time (such as 1 minute, 2 minutes or 3 minutes, etc.), to ensure safety, the stove control unit will automatically control the monostable valve assembly on the corresponding side to open the valve to switch the stir-fry mode to high fire mode.

[0039] In a preferred embodiment, the gas stove includes a gas supply assembly, which includes a knob valve body assembly 1, a medium and small fire gas supply channel 3, and a high fire gas supply channel 4. The monostable valve assembly 6 is arranged on the high fire gas supply channel 4. The input end of the knob valve body assembly 1 is used to receive the input of gas, and the output end of the knob valve body assembly 1 is respectively connected to the input end of the medium and small fire gas supply channel 3 and the input end of the high fire gas supply channel 4. The output end of the medium and small fire gas supply channel 3 and the output end of the high fire gas supply channel 4 are respectively used to supply gas to the center ring fire 21 and the outer ring fire 22; the input end and output end of the monostable valve assembly 6 are respectively connected to the high fire gas supply channel 4, and the input end and output end of the monostable valve assembly 6 are arranged on the high fire gas supply channel 4 in sequence along the gas supply direction. The monostable valve assembly 6 is used to adjust the gas flow at the output end of the high fire gas supply channel 4, so that the high fire gas supply channel 4 has a high fire mode and a stir-fry mode.

[0040] When the monostable valve assembly 6 on the high-fire gas transmission channel 4 is in the suction state, the gas flow rate at the output end of the high-fire gas transmission channel 4 increases, and the high-fire gas transmission channel 4 is in the stir-fry mode. When the monostable valve assembly 6 on the high-fire gas transmission channel 4 is in the open state, the gas flow rate at the output end of the high-fire gas transmission channel 4 decreases, and the high-fire gas transmission channel 4 is in the non-stir-fry mode. The output end of the knob valve body assembly 1 is used to supply gas to both.

[0041] The present invention is provided with at least one knob valve body assembly 1, that is, when it is a single-burner gas stove, there is only one knob valve body assembly 1, and when it is a double-burner gas stove, there are two knob valve body assemblies 1, divided into a left knob valve body assembly and a right knob valve body assembly. In the case of a double-burner gas stove, the two burners correspond to two sets of gas supply assemblies, divided into a left gas supply assembly and a right gas supply assembly, and the gas supply assemblies on both sides have the same structure. When in use, the input end of the knob valve body assembly 1 is connected to the external gas supply pipe, and the output ends of the medium and small fire gas supply channel 3 and the high fire gas supply channel 4 are respectively connected to the center ring fire 21 and the outer ring fire 22, so that the installation can be completed, and the installation difficulty is small. The present invention has a simple structure, can be adapted to various types of burners, has strong versatility, and is low in cost.

[0042] In a preferred embodiment, the monostable valve assembly 6 includes a stir-frying gas transmission channel 5 and a steady-state valve 62 arranged therein. The stir-frying gas transmission channel 5 is connected in parallel with the high-fire gas transmission channel 4, and the input and output ends of the stir-frying gas transmission channel 5 are arranged along the transmission direction of the high-fire gas transmission channel 4; the steady-state valve 62 controls the on-off of the stir-frying gas transmission channel 5; the monostable valve assembly 6 also includes a stir-frying valve core 61 and a stir-frying chamber 63. The stir-frying chamber 63 is connected to the high-fire gas transmission channel 4. The stir-frying valve core 61 is arranged in the stir-frying chamber 63. The input end of the stir-frying gas transmission channel 5 is connected to the stir-frying chamber 63. The steady-state valve 62 realizes the on-off of the stir-frying gas transmission channel 5 by controlling the stir-frying valve core 61. When the stir-fry gas supply channel 5 is completely closed by the steady-state valve 62 and the stir-fry valve core 61 (that is, the valve is open), only the high-fire gas supply channel 4 is used to transport gas, that is, it is in high-fire mode; when the stir-fry valve core 61 is completely opened (that is, the suction valve), the stir-fry gas supply channel 5 and the high-fire gas supply channel 4 are in parallel, and the channel cross-section for transporting gas and the flow rate of transported gas become larger. At this time, it is in stir-fry mode, and the channel cross-section for transporting gas reaches a maximum value; of course, in some embodiments, the cross-sectional area of ​​the channel for transporting gas is different by opening the stir-fry valve core to different degrees to achieve the size adjustment of the stir-fry mode.

[0043] In a preferred embodiment, a gas output nozzle 7 is also provided on the high-fire gas supply channel 4. The stir-frying jet hole 71 of the gas output nozzle 7 is arranged toward one end of the outer ring fire 22. The gas is transported to the outer ring fire 22 by the stir-frying jet hole 71 of the gas output nozzle 7. The output end of the stir-frying gas supply channel 5 is a stir-frying gas outlet 51. The stir-frying gas outlet 51 is connected to the stir-frying jet hole 71, and the stir-frying gas outlet 51 is a drill hole opened by the gas output nozzle 7 at the stir-frying jet hole 51 and inclined toward the stir-frying jet hole 71.

[0044] In a preferred embodiment, the steady-state valve 62 further includes a reset spring, which is disposed between the stir-frying valve core 61 and the stir-frying chamber 63 . The reset spring provides a restoring force to enable the stir-frying valve core to block the stir-frying gas transmission channel 5 .

[0045] In a preferred embodiment, the cross-sectional area of ​​the stir-fry gas channel 5 is smaller than that of the high-fire gas channel 4. The gas flow rate output by the medium-low heat gas channel 3 is smaller than that output by the high-fire gas channel 4. The monostable valve assembly 6 is detachably connected to the high-fire gas channel 4.

[0046] In a preferred embodiment, the gas supply assembly also includes an outer ring ejector pipe 211 and a center ring ejector pipe 221. The input end of the outer ring ejector pipe 211 is connected to the output end of the large fire gas transmission channel 4, and the input end of the center ring ejector pipe 221 is connected to the output end of the medium and small fire gas transmission channel 3. The outer ring ejector pipe 211 is used to transport gas to the outer ring fire 22, and the center ring ejector pipe 221 is used to transport gas to the center ring fire 21.

[0047] In a preferred embodiment, the ignition micro switch and the high-fire micro switch are both provided on the knob valve body assembly 1 of the gas stove, and the two are spaced apart along the circumference of the knob valve body assembly 1 .

[0048] Rotate the knob valve assembly 1 (the structure of the knob valve assembly 1 is conventional) on the gas stove until the ignition microswitch is closed to perform the ignition operation. Gas enters the knob valve assembly 1 through the air passage and enters the medium and low-fire gas supply channel 3. The gas in the medium and low-fire gas supply channel 3 passes through the center nozzle, flows into the center ring ejector tube 221, and then passes through the center mixing chamber and enters the center ring fire 21. The gas is separated by the fire holes of the center ring fire 21, and the electric spark ignites the gas to produce a flame. Continue rotating the knob valve assembly 1 until the high-fire microswitch is closed. Gas enters the knob valve assembly 1 through the air passage and enters the high-fire gas supply channel 4. The gas flows through the monostable valve assembly 6. Because the stable valve 62 is in the closed state (i.e., the valve is open), the stir-fry valve core 61 blocks the stir-fry gas supply channel 5, preventing gas from passing through. The gas can only flow out through the main channel of the stir-fry nozzle 7, enter the outer ring ejector tube 211, and then enter the outer ring mixing chamber. Finally, the gas is separated by the outer ring fire 22 and ignited by the center fire. When using the stir-fry function, lightly tap the stir-fry start button, which opens the steady-state valve 62 (also known as the suction valve) in the aforementioned manner, increasing the firepower to the stir-fry mode. Specifically, upon receiving the signal, the stove control unit 8 controls the steady-state valve 62 to open (also known as the suction valve), causing the stir-fry valve core 61 to leave the stir-fry gas channel 5. A gas branch is generated in the high-fire gas channel 4, which then flows through the stir-fry gas channel 5 and the main gas channel of the stir-fry nozzle 7 and enters the outer ring ejector tube 211. During this process, due to the addition of a gas branch, the cross-sectional area of ​​the gas flow channel increases, and the gas pressure remains almost unchanged when the stove activates the stir-fry function. According to the flow formula, flow rate = flow rate × flow channel cross-sectional area, it can be seen that the gas flow rate increases. More gas enters the outer ring ejector tube 211, passes through the outer ring mixing chamber, and passes through the outer ring flame 22, generating a flame. The outer ring flame is clearly longer than before the stir-fry function was activated, and the overall heat load is greater. The gas flow within the valve body is shown as an arrow. This monostable valve assembly can achieve the function of freely and conveniently controlling gas flow without changing the overall structure of existing gas stove products on the market, simply by cleverly improving the existing valve body structure. Through the clever design of the stir-fry nozzle, the stir-fry gas transmission channel 5 is integrated into the traditional gas nozzle. One or more stir-fry channels are created by drilling holes in the inner side of the outer end of the nozzle main nozzle in an inclined direction toward the nozzle mouth. This effectively solves the problem of existing stir-fry gas stoves on the market that high smoke after stir-frying requires the design of an additional supplementary air intake system. Compared with some stoves with multiple nozzle designs, this design avoids the need to change the burner, is more versatile, and is more beautiful and neat than existing products on the market, and is more cost-effective.

[0049] In a preferred embodiment, the linkage module includes a stove linkage module arranged on the gas stove and a range hood linkage module arranged on the range hood, and the stove linkage module is signal-connected with the range hood linkage module; the linkage module is a 433 radio frequency module, a 2.4G radio frequency module, a Bluetooth module or a WIFI module.

[0050] In a preferred embodiment, the range hood is further provided with a prompt element in signal communication with the range hood control unit. The prompt element prompts whether the stir-fry start button is available or unavailable according to the control of the range hood control unit. Specifically, the prompt element can be a voice announcement speaker that plays a voice prompt to indicate whether the stir-fry start button is available or unavailable. The prompt element can also be a prompt light that turns off to indicate that the stir-fry start button is unavailable and turns on to indicate that the stir-fry start button is available. Alternatively, the prompt element can be a red light that indicates that the stir-fry start button is unavailable and a green light that indicates that the stir-fry start button is available.

[0051] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
