New description: [New technical field] In more detail, it refers to the safety department of a stove with the furnace and the controller. [Prior Art] According to the conventional gas stoves that use gas as fuel, they can be roughly classified into gas stoves, ovens, heaters, etc., in order to improve the safety during use, the gas stoves currently seen on the market. The following two designs are adopted to produce the effect of maintaining the safety of the user. First, it is mainly used to add control functions such as shutdown and timed shutdown in the furnace body of the gas stove, and the second is A structure is provided on the panel of the furnace body to prevent the gas switch from being directly activated to ignite the fire. There are quite a few patents related to the two designs, which are not described here. However, regardless of the type of safety design, it is necessary to change the existing structure of the gas stove, and the production cost is inevitably relatively increased, which affects the profit of the product marketing. Secondly, the conventional gas stoves use gas switches to control the flow of gas to the burner (bake) for combustion. However, the gas switches that are currently seen cannot be used to control large-flow gas (such as natural gas of more than 100,000 btu). Therefore, the conventional gas stoves still have limitations in their scope of use.

The differential pressure film 14 is a flexible differential pressure film of a conventional differential pressure disc between the cover body 24 and the open end of the cover body 28 for partitioning the space between the two to form an inner and outer pressure chamber 54, 56. The control device 15 is disposed in the chamber η Μ, a closure member 60, a voltage stabilizing member 62 and an elastic member 64. ^ "动# 5 8 system through the shaft hole 5 of the branch block 13 〇 and the connection pressure difference = 14 / the closure 60 is attached to the other end of the drive rod 58 and corresponding to the control port $ two coated parts 62 6 is formed on the side of the closing member 60. The flow regulating portion of the gas flow path is 6: the rod-shaped portion 66 is opposite to the regulating portion 68 when the regulating portion 38 ^ 14 is disposed at the connecting portion 6.

In addition, the main body 26 further defines a receiving portion 72 of the gas flow passage 36. The flow regulating rod 74 is movably disposed on the receiving opening 72. The outlet end of the exhaust solenoid valve 17 can be connected to a female ignition igniter (not shown) for igniting the oven 20. Therefore, the safety controller 1 is activated in the following manner: As shown in the second figure, when the safety controller 10 is not actuated, the gas can enter the external pressure chamber 56 via the pressure solenoid valve 16, so that the The outer pressure chamber 56 generates air pressure to push the differential film 14 so that the closing member 6 紧密 can tightly seal the control port 38 so that the gas in the chamber 30 does not flow into the gas flow path 36 and the air flow. Road 3 4. As shown in FIG. 5, when the power switch 70 is activated, the pressurizing solenoid valve 16 and the exhaust solenoid valve 17 can be actuated by energization, and the pressurizing solenoid valve becomes a normally closed state. 17 becomes a normally open state. The gas in the external pressure chamber 56 can flow to the parent fire igniter with the opening of the exhaust solenoid valve 17, and the gas switch 203 of the stove 20 can be rotated to ignite the mother. The fire, when the mother fire is ignited, the controller of the stove 2 can further actuate the pressurizing solenoid valve 16 and the exhaust solenoid valve 17, so that the pressurizing solenoid valve 16 is normally open, and the exhaust solenoid valve 17 becomes In the normally closed state, the gas pressure in the inner pressure chamber 54 can exceed the air pressure of the outer pressure chamber 56, and the pressure film 14 is pushed toward the outer pressure chamber 56. The drive rod 58 can be moved, and the closure member 60 is no longer Close the control port 38, the gas can flow through the control port 38, M319383 • the rolling muscle channel 34 to the stove 2〇, then the mother fire can ignite the stove 2 (main fire) at this time, due to the row The gas solenoid valve 丨7 is in a closed state, and the pressure difference Μ 14 is no longer moved, thereby fixing the closing member 6〇 to the unclosed control port 3 The position of 8 is such that the gas of sustainable output is used for the combustion of the stove 20 (main fire), and the main fire is ignited by the mother fire to prevent the stove 20 from being ignited under the condition of large gas flow. Risk of deflagration. Secondly, the regulating portion 68 of the voltage stabilizing member 62 can control the increase and decrease of the air passage cross section with respect to the control port 38, and can generate a stable voltage supply effect of the air supply. As can be seen from the above, the safety controller 1 can control whether the gas flows to the stove 2 () by being disposed upstream of the gas source of the stove 20. 'When the person wants to start the gas switch 203 to ignite the fire The power switch 70 must be activated first. The safety controller 1 can be actuated to allow gas to flow into the stove 20. The gas switch 203 can ignite the fire, and the utility model can be used for the safety function. Moreover, under the existing structure without changing the stove, only the safety controller 10 needs to be added at the front end of the gas inlet of the stove, so that the effect of making the stove safer is obtained, and the creation is obviously economical. value. Further, the stove 20 may be a conventional gas stove for generating heat by burning gas such as a heater. Secondly, the safety controller 10 can also be coupled with a pressure solenoid valve 16 and an exhaust solenoid valve 17 to electrically connect a temperature setter and a temperature sensor (not shown). The temperature setter can be used to set the furnace. The heating temperature of the head, the sensing end of the M319383 temperature sensor is placed beside the burner of the stove 20. When the temperature sensor senses that the combustion temperature of the burner is not up to expectations, the controller will send a control signal to re-open the closed exhaust solenoid valve 17 to discharge a small amount of gas in the external pressure chamber 56, so that the pressure The differential film 14 is moved by the change of the pressure, and the closing member 60 is further away from the regulating port 38, and the gas flow rate of the outlet air passage 34 is increased to increase the flame of the burner to a preset temperature. Conversely, when the temperature sensor senses that the combustion temperature of the burner is overheated, the control sends a control signal, causing the pressure solenoid valve 16 to appeal to the valve hole, and a small amount of gas enters the external pressure chamber 56, so that The differential pressure film 14 is pushed toward the inner pressure chamber 54 to reduce the diameter of the gas flow passage between the sealing member 60 and the control port 38, thereby reducing the gas flow rate of the outlet air passage 34 and reducing the flame of the burner. Up to the preset temperature. Therefore, the temperature of the combustion head of the burner can be induced by the temperature sensor to cause the pressure electromagnetic solenoid 16 and the exhaust solenoid valve 17 to automatically change the distance between the closing member 6 and the control port 38, thereby changing the air outlet passage 34. The output of the gas flow is automatically adjusted to the effect of the furnace head temperature. In addition, the temperature setting device can be manually set and adjusted by the user to adjust the heating temperature of the burner. The remote control device can also be used to generate the remote control operation mode. The safety control of the provided stove can directly break through the limitation of the design of traditional gas stoves, and solve the problem of missing the former gas switch. The reason is that this (four) disc is in line with the new profit, and is proposed according to law. Application.
