Description

Technical Field

[0001] The utility model relates to a gas stove fire control device, and in particular to providing a gas stove timer switch capable of timing to adjust the fire strength and shut down the fire, and a gas stove safety device further equipped with a temperature sensor capable of adjusting the fire strength or shutting down the fire according to timing conditions or temperature conditions. Background Art

[0002] Generally, a gas stove is provided with an igniter corresponding to each burner head. Each igniter mainly has an ignition switch shaft for igniting and controlling the intensity of the fire, and is also provided with an ignition switch knob sleeved with the ignition switch shaft. When in use, the ignition switch knob is turned, and the ignition switch knob drives the ignition switch shaft to rotate in the direction of igniting or turning off the gas.

[0003] Currently, the burners of gas stoves on the market usually adopt a dual fire design with external fire and internal fire. When in use, after lighting the fire, the ignition switch knob can be turned in the ignition direction or the fire-off direction to adjust between strong and medium fire of the gas stove. The ignition switch knob can be continuously turned in the ignition direction to the maximum limit, so as to turn off the external fire and keep only the internal fire, and adjust the fire of the gas stove to a weak fire state.

[0004] Furthermore, a gas stove timing switch device is known, which is attached to the gas stove panel and connected to its ignition switch shaft. The timing function can be activated when the user turns the gas stove ignition switch knob to a suitable fire intensity. After a designed time has passed, the ignition switch knob and the ignition switch shaft are driven to turn off the fire, thereby avoiding the risk of food burning or even causing a fire due to forgetting to turn off the fire.

[0005] However, the existing gas stove timer switch can only control the ignition switch knob to turn off the fire after being started, and cannot automatically turn the ignition switch knob to the low fire direction to continue cooking for a period of time after a set time has passed. For cooking needs that usually require boiling with high heat first and then switching to low heat to continue simmering, the gas stove timer switch cannot be used to automatically adjust the fire strength and then turn off the fire, so there is still room for improvement. Utility Model Content

[0006] In view of this, the main purpose of the utility model is to provide a gas stove timer switch that can adjust the intensity of the fire and turn off the fire, and further cooperate with a temperature sensor to form a gas stove safety device that can adjust the intensity of the fire or turn off the fire according to timing conditions or temperature conditions.

[0008] By utilizing the above-mentioned structural features, the gas stove timing switch of the utility model can set relevant action modes and corresponding control conditions through the switch human-machine module. For example, after the gas stove operates for a set time with an adjusted fire intensity, the switch control module can drive the knob together with the ignition switch shaft to the fire-off position according to the set mode and control conditions; or after operating for a set time with the adjusted fire intensity, the steering conversion module and the switch drive module are controlled to operate and drive the knob together with the ignition switch shaft to the low fire position. After operating for a set time with low fire, the steering conversion module and the switch drive module are controlled to operate and drive the knob together with the ignition switch shaft to the fire-off position, so as to achieve the automatic control effect of timing to adjust the fire intensity and turning off the fire.

DETAILED DESCRIPTION

[0032] The utility model mainly provides a gas stove timer switch device capable of timing and adjusting the intensity of the fire and shutting down the fire, and further equipped with a temperature sensor, so as to form a gas stove safety device capable of adjusting the intensity of the fire or shutting down the fire according to the timing condition or the temperature condition. Figures 1 to 3 As shown, the gas stove timer switch 10 of the utility model basically comprises:

[0033] A switch body 11 has a base 111 and a knob 112 for connecting to the ignition switch shaft 41 of the gas stove 40; during implementation, the base 111 can be a casing configuration for accommodating related components, and the base 111 is installed on the panel of the gas stove 40 relative to the ignition switch shaft 41.

[0034] A switch electrical unit 12 is electrically integrated with a switch driving module 121 for driving the knob 112 to rotate relative to the base 111, a switch power module 122, a switch control module 123 with a timing function, a switch human-machine module 124, and a direction conversion module 125 for changing the direction of the knob 112 at the switch body 11.

[0035] During implementation, the switch driving module 121 includes: a servo motor (not shown), a gear set (not shown) constituting a transmission connection between the servo motor and the knob 112; in this embodiment, the switch control module 123 and the steering conversion module 125 are presented in the form of a structure integrated into a microcontroller (MCU), and the steering conversion module 125 controls the current direction of the servo motor.

[0036] The switch human-machine module 124 includes: a liquid crystal display panel 1241, at least one function selection button 1242, a timer setting knob 1243, and a timer start button 1244; the liquid crystal display panel 1241 presents information corresponding to the at least one function selection button 1242, the timer setting knob 1243, and the timer start button 1244.

[0037] Furthermore, the switch electrical unit 12 can further be electrically integrated with a switch audio module 126 at the switch body 11; during the operation or operation of the gas stove timing switch 10, the switch audio module 126 can emit corresponding audio or voice according to the set mode, thereby improving the practicality and operational convenience of the overall gas stove timing switch 10.

[0038] When the gas stove timer switch 10 of the present invention is used, the relevant action mode and corresponding control conditions can be set through the switch human-machine module 124; for example, Figure 4 As shown, set the flame to high power and then turn off the flame after setting time (20 minutes); or Figure 5 As shown, first set the high fire to operate for a set time (20 minutes) and then switch to low fire to operate for a set time (10 minutes) before turning off the fire.

[0039] exist Figure 5 In the embodiment shown, when the user rotates the knob 112 to complete ignition and turns the knob 112 to the high fire state, the user presses the timing start button 1244, and the switch control module 123 controls the steering conversion module 125 and the switch drive module 121 to operate according to the set action mode and the corresponding control conditions (timing conditions) after the high fire operation for 20 minutes, and drives the knob 112 together with the ignition switch shaft 41 to the low fire position (such as Figure 6 shown).

[0040] Then, after operating at low flame for 10 minutes, the steering conversion module 125 and the switch drive module 121 are controlled to operate, driving the knob 112 and the ignition switch shaft 41 to turn to the off position (such as Figure 7 As shown), the automatic control effect of timing adjustment of the intensity of the stove fire and turning off the stove fire can be achieved to meet the cooking needs of dishes that need to be boiled first and then switched to low heat to continue cooking.

[0041] The utility model also provides a gas stove safety device that can adjust the intensity of the fire and turn off the fire according to the timing condition or temperature condition. Figure 8 and Fig. 9 As shown, the gas stove safety device basically includes: a gas stove timer switch 10 and a temperature sensor 20.

[0042] Please also refer to Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown, the gas stove timing switch 10 is composed of a switch body 11 and a switch electrical unit 12; the switch body 11 has a base 111, and a knob 112 for connecting the ignition switch shaft 41 of the gas stove 40 is provided on the base 111.

[0043] The switch electrical unit 12 is electrically integrated with a switch driving module 121 for driving the knob 112 to rotate relative to the base 111, a switch power module 122, a switch control module 123 with a timing function, a switch human-machine module 124, a direction conversion module 125 for changing the direction of the knob 112, and a switch wireless signal communication module 127 for establishing a signal transmission connection with an external device.

[0044] As mentioned above, the switch electrical unit 12 can further be electrically integrated with a switch audio module 126 at the switch body 11; the switch drive module 121 includes: a servo motor (not shown), a gear set (not shown) constituting a transmission connection between the servo motor and the knob 112; the switch control module 123 and the steering conversion module 125 are presented in the form of a structure integrated into a microcontroller (MCU), and the steering conversion module 125 controls the current direction of the servo motor.

[0045] The switch human-machine module 124 includes: a liquid crystal display panel 1241, at least one function selection button 1242, a timer setting knob 1243, and a timer start button 1244; the liquid crystal display panel 1241 presents information corresponding to the at least one function selection button 1242, the timer setting knob 1243, and the timer start button 1244.

[0046] As for the temperature sensor 20, it is composed of a temperature sensor body 21 and a temperature sensor electrical unit 22; the temperature sensor electrical unit 22 is electrically integrated with a temperature sensing module 221, a temperature sensor power module 222, a temperature sensor control module 223, and a temperature sensor wireless signal communication module 224 for forming a signal transmission connection with the switch wireless signal communication module 127 at the temperature sensor body 21.

[0047] Similarly, the thermosensor electrical unit 22 can further be electrically integrated with a thermosensor audio module 225 at the thermosensor body 21. During the operation of the gas stove 40, the thermosensor audio module 225 can emit corresponding audio or voice according to the set mode and temperature conditions to remind the user to pay attention to the temperature changes of the gas stove 40.

[0048] In this embodiment, the temperature sensor body 21 is presented in the form of a pot cover button structure, which can be installed on the pot cover 51. The pot cover 51 covers a pot 50 to sense the temperature information inside the pot 50, so that the corresponding gas stove timer switch 10 can use it as a basis for adjusting the fire intensity or immediately turning off the fire.

[0049] For example, the gas stove safety device of the present invention can be set by the gas stove timer switch 10 to directly turn off the fire after the adjusted fire operation setting time; or set to first adjust the fire operation setting time and then turn off the fire after the low fire operation setting time.

[0050] The gas stove timing switch 10 can also cooperate with the temperature information of the temperature sensor body 21 to first control the steering conversion module 125 and the switch drive module 121 to operate, so that the gas stove 40 is maintained at a preset temperature condition for a period of time, and then control the steering conversion module 125 and the switch drive module 121 to change the fire intensity of the gas stove 40, so that the gas stove 40 can be turned off after operating at the adjusted temperature condition for a period of time.

[0051] In particular, when the gas stove timing switch 10 receives the temperature information from the temperature sensor 20 that has reached the safety setting value, even if the gas stove 40 is still operating under the timing conditions originally set by the gas stove timing switch 10, the temperature conditions at that time must be given priority to directly control the switch drive module 121, or simultaneously control the steering conversion module 125 and the switch drive module 121 to drive the knob 112 to rotate in the direction of turning off the fire, thereby immediately turning off the fire to avoid danger.

[0052] Please also refer to Fig.10 As shown, when the gas stove safety device of the present invention is implemented, it can further include at least one smart phone 30 for controlling the operation of the gas stove timer switch 10 and the temperature sensor 20 .

[0053] Not only can the gas stove timer switch 10 and the temperature sensor information 20 be received through each smart phone 30 to instantly grasp the operating status of the gas stove 40, but the action mode or control condition of the gas stove timer switch 10 and the temperature sensor 20 can also be adjusted at any time according to actual needs.

[0054] Specifically, the gas stove timer switch provided by the utility model can directly turn off the fire after the fire intensity is adjusted to a set time; or it can first operate the fire intensity at a set time and then switch to a low fire to operate for a set time before turning off the fire, thereby achieving an automatic control effect of timing to adjust the fire intensity and turn off the fire, so as to meet the cooking needs of cooking that needs to be boiled first and then switched to a low fire to continue boiling.

[0055] In addition, the gas stove timer switch provided by the utility model can be further constructed with a temperature sensor to form a gas stove safety device that can adjust the fire strength and turn off the fire according to timing conditions or temperature conditions.

[0056] Even more, the gas stove safety device of the utility model can be further integrated with at least one smart phone, so that the user can receive the information of the gas stove timer switch and temperature sensor through the smart phone, and instantly grasp the operating status of the gas stove. The action mode or control conditions of the gas stove timer switch and temperature sensor can be adjusted at any time according to actual needs, thereby improving the safety and convenience of operation of the gas stove in a relatively more active and reliable way.
