[0002] Household gas stoves convert the chemical energy of gas into heat energy to cook dishes and process food, which brings great convenience to people's lives. However, it is easy to cause overburning and gas leakage due to forgetting to turn off the fire. The timer gas stove can solve the problem of forgetting to turn off the fire after cooking. The timer gas stove in the prior art is usually a touch-controlled structure, that is, the timing module is installed on the back of the stove, and the mode and duration are selected by touch. The positioning module needs to be powered by a special wiring harness during installation, and a wiring harness is also required to connect the controller to feed back the timing signal to the controller. The assembly is cumbersome, and the user needs to select the duration by multiple touches, which is relatively complicated to operate and time-consuming.

[0050] Embodiment 1

[0051] Figure 1 A schematic structural diagram of a gas stove switch device provided in this embodiment is shown. Figure 2 The exploded schematic diagram of the gas stove switch device provided in this embodiment is shown. Figure 3 FIG. 2 shows a cross-sectional schematic diagram of the gas stove switch device provided in this embodiment. Figure 1-Figure 3 As shown, this embodiment provides a gas stove, which includes a stove panel 100 and a gas stove switch device. The stove panel 100 is provided with an avoidance hole; the gas stove switch device includes a control valve 1, a firing knob 2 and a timing module 3. The control valve 1 includes a valve body 11 and a valve stem 12 rotatably arranged on the valve body 11. The valve body 11 is arranged below the stove panel 100. The valve stem 12 passes through the avoidance hole of the stove panel 100 and is connected to the firing knob 2. The firing knob 2 can drive The valve stem 12 rotates; the timing module 3 includes a timing dial assembly 31 and a timing paddle switch 32, the timing dial assembly 31 is sleeved on the valve stem 12 and is located between the valve body 11 and the firing knob 2, and the timing paddle switch 32 is located on one side of the valve stem 12; the timing paddle switch 32 includes a fixed end 321 arranged on the valve body 11 and a timing paddle 322 movably arranged on the fixed end 321, and rotating the timing dial assembly 31 can drive the timing paddle 322 to move to transmit a timing signal.

[0052] In the gas stove provided in this embodiment, rotating the fire knob 2 can drive the valve stem 12 to rotate to realize the ignition operation of the stove; rotating the timing dial assembly 31 can drive the timing paddle 322 to move, which can transmit the timing signal, effectively avoiding accidents such as overburning and gas leakage caused by the user forgetting to turn off the fire, and ensuring the safety of the gas stove; in addition, the timing control of the stove can be achieved through a simple twisting action, which is convenient and quick to operate, and can also omit unnecessary wiring harnesses for easy assembly.

[0053] In this embodiment, the timing paddle 322 is swingably disposed on the fixed end 321, and can automatically reset after the timing paddle 322 swings a preset angle relative to the fixed end 321. It is defined that when the timing paddle 322 swings a preset angle relative to the fixed end 321 and resets, it is defined as one action. The timing paddle 322 moves once and the controller records the unit time length as t. Of course, in other embodiments, the timing paddle 322 can also be slidably disposed on the fixed end 321, and can automatically reset after the timing paddle 322 slides a preset distance relative to the fixed end 321. For the convenience of description, this embodiment is described by taking the timing paddle 322 swingably disposed on the fixed end 321 as an example.

[0054] Figure 4 A schematic structural diagram of the control valve 1 provided in this embodiment is shown. Figure 5 FIG. 2 shows a schematic diagram of the structure of the firing knob 2 provided in this embodiment. Figure 4-Figure 5 As shown, the valve stem 12 is engaged with the firing knob 2 to ensure that the firing knob 2 can drive the valve stem 12 to rotate, thereby realizing the ignition operation of the stove. Optionally, a plug hole 21 is provided on the firing knob 2, and the valve stem 12 can be plugged into the plug hole 21 to realize the engagement between the firing knob 2 and the valve stem 12. It should be noted that the shape of the plug hole 21 is not circular, and the cross-sectional shape of the top of the valve stem 12 is the same as the shape of the plug hole 21, so as to prevent the firing knob 2 and the valve stem 12 from rotating relative to each other, thereby affecting the firing efficiency.

[0055] Exemplarily, the shape of the plug hole 21 can be a regular polygon, an irregular polygon, or an irregular shape composed of connected straight lines and curves. In this embodiment, the cross-sectional shape of the top of the valve stem 12 is D-shaped, and a limiting plate is also provided on the top of the valve stem 12. The plug hole 21 is D-shaped, and a limiting hole connected to the plug hole 21 is also provided on the firing knob 2. The valve stem 12 can be plugged into the plug hole 21, and the limiting plate can be plugged into the limiting hole of the firing knob 2, thereby further ensuring the fixing effect between the firing knob 2 and the valve stem 12.

[0056] Figure 6 A schematic structural diagram of the manual dial 311 provided in this embodiment is shown. Figure 7 FIG. 3 shows a schematic diagram of the structure of the transmission dial 312 provided in this embodiment. Figure 6-Figure 7Combined with Figure 2 As shown, the timing dial assembly 31 includes a manual dial 311 and a transmission dial 312 arranged and connected in the upper and lower parts, and the transmission dial 312 is provided with a plurality of timing toggle teeth spaced along its circumferential direction; when the timing paddle 322 is located at the middle position of the fixed end 321, it can extend between two adjacent timing toggle teeth, and when the timing paddle 322 swings a preset angle, it can be disengaged from between the two adjacent timing toggle teeth and reset. By setting the connected manual dial 311 and the transmission dial 312, the manual dial 311 can be set above the stove panel 100 to facilitate the user to rotate, and the transmission dial 312 and the timing paddle switch 32 are set below the stove panel 100 to prevent the user from accidentally touching and ensure the user's safety. In addition, in this embodiment, when the user rotates the timing dial assembly 31, the timing paddle 322 swings a preset angle and can be disengaged from between the two adjacent timing toggle teeth of the transmission dial 312 and reset, at which time, the controller of the gas stove records the unit time length as t. With this setting, each time the user turns on the stove for use, the timing paddle 322 is in the middle position of the fixed end 321, that is, there is no timing duration in the initial state of the gas stove. This can avoid the situation where the user forgets to reset the timing module 3 after using the gas stove, resulting in an initial timing duration when the gas stove is restarted, and the initial timing duration cannot meet the current cooking needs, resulting in the flameout in the middle of cooking.

[0057] Preferably, the timing paddle switch 32 is a two-way paddle switch. When the user turns the manual dial 311 clockwise, the timing duration increases, and when the user turns the manual dial 311 counterclockwise, the timing duration decreases, so as to meet the cooking time requirement, improve the taste of cooked food, and enhance the user experience. It should be noted that the two-way paddle switch is a prior art, and the specific structure of the two-way paddle switch is not described in detail in this embodiment.

[0058] It should be noted that the middle position of the fixed end 321 refers to the timing paddle 322 being located at the "0 gear" of the fixed end 321. When the timing paddle 322 swings clockwise at a preset angle, the timing paddle 322 is located at the "1 gear" of the fixed end 321. When the timing paddle 322 swings counterclockwise at a preset angle, the timing paddle 322 is located at the "-1 gear" of the fixed end 321. In this embodiment, when the timing paddle 322 is set to be located at the "1 gear" of the fixed end 321, the controller adjusts the timing duration to increase; when the timing paddle 322 is set to be located at the "-1 gear" of the fixed end 321, the controller adjusts the timing duration to decrease. Of course, in other embodiments, the corresponding relationship between the increase or decrease of the timing duration and the position of the timing paddle 322 can also be adjusted according to the installation position of the timing paddle switch 32, and this embodiment is not limited to this. In addition, the preset angle is the angle at which the timing paddle 322 swings from the "0 gear" of the fixed end 321 to the "1 gear" or from the "0 gear" of the fixed end 321 to the "-1 gear". This embodiment does not limit the specific value of the preset angle, and designers can make adjustments based on the model of the timing paddle switch 32 they choose.

[0059] It should be noted that the manual dial 311 and the transmission dial 312 are both sleeved on the valve stem 12, but the timing paddle 322 can extend between two adjacent timing dial teeth of the transmission dial 312, and the force exerted by the timing paddle 322 on the transmission dial 312 is greater than the friction between the transmission dial 312 and the valve stem 12. Therefore, the manual dial 311 and the transmission dial 312 can both rotate relative to the valve stem 12, but cannot rotate with the valve stem 12.

[0060] like Figure 6-Figure 7 As shown, one of the manual dial 311 and the transmission dial 312 is provided with a connection slot, and the other is provided with a connection convex, which is engaged with the connection slot to achieve the connection between the manual dial 311 and the transmission dial 312, so that when the user turns the manual dial 311, the transmission dial 312 can be driven to rotate synchronously. Specifically, the manual dial 311 includes a first dial 3111 and a first connecting portion 3112 connected to each other, and the transmission dial 312 includes a second dial 3121 and a second connecting portion 3122 connected to each other, the first dial 3111 is located above the first connecting portion 3112, the second dial 3121 is located below the second connecting portion 3122, and the first connecting portion 3112 and the second connecting portion 3122 are engaged with each other. In this embodiment, the first connection part 3112 and the second connection part 3122 are both cylindrical structures, and the first connection part 3112 is sleeved outside the second connection part 3122 to increase the contact area between the first connection part 3112 and the second connection part 3122 and improve the stability of the connection between the two.

[0061] In this embodiment, a connection protrusion is provided on the inner wall of the first connection part 3112, and a connection slot is provided on the outer wall of the second connection part 3122. Optionally, there are multiple connection protrusions, and the multiple connection protrusions are arranged at intervals along the circumference of the first connection part 3112, and each connection protrusion can correspond to a connection slot. Of course, in other embodiments, the connection protrusion can also be arranged on the outer wall of the second connection part 3122, and the connection slot can be arranged on the inner wall of the first connection part 3112, which can also achieve the above effect.

[0062] like Figure 6-Figure 7 Combined with Figure 3 As shown, an elastic member 313 is provided between the manual dial 311 and the transmission dial 312. By providing the elastic member 313, on the one hand, when the user turns the firing knob 2 to perform the ignition operation, the firing knob 2 needs to be pressed downward at the same time. The provision of the elastic member 313 can provide a certain travel space for the manual dial 311 to ensure the normal pressing and ignition operation of the firing knob 2; on the other hand, the elastic member 313 can also limit the transmission dial 312 to prevent the transmission dial 312 from moving along the axis direction of the valve stem 12, causing the timing paddle 322 to disengage from the two adjacent timing toggle teeth of the transmission dial 312, thereby affecting the timing operation. In this embodiment, the elastic member 313 is a spring, which has a simple structure, is easy to assemble, and is easy to obtain materials, which can reduce production costs.

[0063] In order to ensure the smooth movement of the manual dial 311 along the axial direction of the valve stem 12, in the present embodiment, the connecting protrusion and the connecting groove are both long strips and extend along the axial direction of the valve stem 12, so as to achieve the effect that the manual dial 311 and the transmission dial 312 can move relative to each other along the axial direction of the valve stem 12, and the manual dial 311 can drive the transmission dial 312 to rotate synchronously when it rotates.

[0064] To facilitate the user to rotate the manual dial 311 , the outer surface of the manual dial 311 is provided with a plurality of anti-slip edges at intervals along its circumference to prevent the user's fingers from sliding relative to the manual dial 311 and affecting the timing operation.

[0065] Embodiment 2

[0066] Figure 8 The flow chart of the gas stove timing control method provided in this embodiment is shown as follows Figure 1 .like Figure 8 Combined with Figure 1-Figure 3 As shown, this embodiment provides a gas stove timing control method, and the gas stove timing control method includes the following steps:

[0067] Step S1: Rotate the timing dial assembly 31 to drive the timing paddle 322 to move and enter the timing mode;

[0068] Step S2: The controller records the single timing duration T n0 =kt;

[0069] Wherein, k is the number of times the timing paddle 322 moves when the timing dial assembly 31 rotates once, and t is the unit duration of one movement of the timing paddle 322 .

[0070] It should be noted that one rotation of the timing dial assembly 31 means that the user manually rotates the timing dial assembly 31 once. At this time, the timing dial assembly 31 can be rotated one circle, half a circle, 1 / 4 circle or 2 / 3 circle. This embodiment does not limit this. After the user releases the timing dial assembly 31 and continues to rotate it, the control is recorded as the second rotation of the timing dial assembly 31. At this time, the total timing duration is accumulated.

[0071] The gas stove timing control method provided in this embodiment only requires a simple twisting action when the user needs to perform a timing operation on the gas stove. The structure is simple and the adjustment process is convenient and quick. The mechanical structure is used to transmit power, so that accurate and reliable electrical signals can be obtained, and no redundant wiring harness is required. The assembly process can also be simplified, so the assembly efficiency is high and the manufacturing cost is low.

[0072] Furthermore, step S2 specifically includes:

[0073] Compare the number of actions V of the timing paddle 322 per unit time t With the preset number of actions V 0 size;

[0074] If V t ≥V 0 , turn the timing dial assembly 31 controller once to record the single timing duration T n0 =kt 1 ;

[0075] If V t <V 0 , turn the timing dial assembly 31 once to record the single timing duration T of the controller n0 =kt 2 ;

[0076] Among them, t 1 >t 2 .

[0077] In this embodiment, the preset number of actions V of the timing paddle 322 per unit time is 0 There is no limitation, and the specific value can be adjusted by the designer according to the actual situation or changed by the user according to his own situation.

[0078] The gas stove timing control method provided in this embodiment, when performing timing operation, the controller of the gas stove will first compare the number of actions V of the timing paddle 322 in a unit time. t With the preset number of actions V 0 The size of V t ≥V 0 , indicating that the user rotates the timing dial assembly 31 at a faster frequency, and the controller will record the single timing duration T n0 =kt 1 ; When V t <V 0 , indicating that the user rotates the timing dial assembly 31 at a slow frequency, and the controller will record the single timing duration T n0 =kt 2 ; and t 1 >t 2 This design can reduce the number of times the user turns the timing dial assembly 31 when timing for a long time, thereby improving the user's timing operation efficiency and enhancing the user's experience. 1 and t 2 The specific value of is not limited, and the specific value can be adjusted by the designer according to the actual situation or changed by the user according to his own situation.

[0079] Fig. 9 The flow chart of the gas stove timing control method provided in this embodiment is shown as follows Figure 2 .like Fig. 9 As shown, in order to facilitate the user to adjust the timing duration in real time according to the current cooking situation, in this embodiment, when the gas stove is in the timing mode, the rotation direction of the timing dial assembly 31 when the nth time is turned;

[0080] If the rotation direction of the timing dial assembly 31 is the first direction, the total timing duration T after the timing dial assembly 31 is turned for the nth time is n =T n-1 +T n0 ;

[0081] If the rotation direction of the timing dial assembly 31 is the second direction, the total timing duration T after the timing dial assembly 31 is rotated for the nth time is n =T n-1 -T n0 ;

[0082] Among them, T n-1 is the total timing duration after the timing dial assembly 31 is rotated for the n-1th time; n is an integer, when n=1, T n-1 =0.

[0083] It should be noted that the gas stove timing control method provided in this embodiment can be implemented by the gas stove provided in the first embodiment, and the timing paddle switch 32 is a two-way paddle switch. Exemplarily, the first direction refers to the clockwise direction, and the second direction refers to the counterclockwise direction, that is, when the user turns the timing dial assembly 31 clockwise, the timing duration increases, and when the user turns the timing dial assembly 31 counterclockwise, the timing duration decreases, so as to meet the cooking time requirements, improve the taste of cooked food, and improve the user experience. Of course, in other embodiments, the first direction can also be defined as the counterclockwise direction, and the second direction can be defined as the clockwise direction.

[0084] To avoid the situation where the timing time is shorter than the cooking time, resulting in the food being undercooked, in this embodiment, after the countdown in the timing mode ends, the human body sensor sends a human activity signal to the controller at intervals of a first preset time;

[0085] If the human body sensor sends a human activity signal to the controller, the controller controls the gas stove to continue working;

[0086] If the human body sensor sends a signal indicating that no one is active to the controller, the controller controls the gas stove to stop working.

[0087] When the countdown in the timing mode ends, if the human body sensor can sense human activity, it means that the user is still in the cooking process at this time, then the controller controls the timing mode to end, but does not turn off the gas stove, so that the user can continue to use the gas stove; if the human body sensor cannot sense human activity, it means that the user is not in the kitchen at this time, and in order to ensure the personal and property safety of the user, the controller controls the gas stove to stop working. It should be noted that this embodiment does not limit the first preset time, and its specific value can be adjusted by the designer according to the actual situation or changed by the user according to his own situation.

[0088] Optionally, the human body sensing element is an infrared sensing switch or a proximity switch.

[0089] Furthermore, when the countdown in the timing mode ends, the human body sensor sends an unattended activity signal to the controller, and the controller controls the alarm to sound an alarm. When the user is stewing food, the user starts the timing mode and leaves the kitchen to rest in the living room. When the timing mode ends, the human body sensor sends an unattended activity signal to the controller, and the controller also controls the alarm to sound an alarm to remind the user to come to the kitchen to check the stewing status of the food, so as to determine whether the gas stove needs to be restarted to prevent the food from not being cooked due to the gas stove being turned off in advance. Optionally, the alarm can be a buzzer or a voice announcer.

[0090] When the gas stove is in the timing mode, if the user turns off the gas stove in advance, the timing mode ends; when the gas stove is restarted, the timing mode starts again. This design can prevent the timing time from accumulating when the user restarts the gas stove and enters the timing mode, resulting in the phenomenon of burning food due to excessive cooking time.

[0091] In order to facilitate the user to observe the current remaining time in the timing mode, a display screen component is provided on the stove panel 100 of the gas stove, and the display screen component can display the current remaining time in the timing mode. By setting the display screen component, it is convenient for the user to know the current timing time in time and adjust it in time according to the cooking situation. In other embodiments, the gas stove includes a voice broadcast component, and the voice broadcast component is configured to broadcast the current remaining time in the timing mode every second preset time, so that the user can know the current timing time in time and adjust it in time according to the cooking situation. It should be noted that this embodiment does not limit the second preset time, and its specific value can be adjusted by the designer according to the actual situation or changed by the user according to his own situation.

[0092] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
