Description

  The present invention detects vibration caused by earthquakes in order to prevent a fire caused by a fall of a gas combustion device due to an earthquake, a fall of flammable material on the gas combustion device, or a spillage of oil from a starch pan in a gas stove. Thus, the present invention relates to a safe gas combustion equipment control device that shuts off gas and stops combustion.

  As a method for detecting the fall of the gas combustion device itself, the fall of the combustible material on the gas combustion device, and the strong shaking during the earthquake, a fall switch having a contact structure using a mechanical conductive ball is used. The fall switch has been widely adopted as a fall detection method for gas combustion equipment because it is easy and inexpensive. In addition, a system that cuts off gas piping routes using emergency earthquake warnings has been considered in recent years, and its adoption is expanding.

  The start in FIG. 1 is, for example, a state where the cooking utensil is put on a gas combustion device that has been ignited (step 111). In the gas combustion device, for example, accelerations in the x-axis direction, the y-axis direction, and the z-axis direction are detected by a built-in acceleration sensor (steps 112, 122, and 132). The accelerations in the x-axis direction, y-axis direction, and z-axis direction are sampled every predetermined time (steps 113, 123, and 133). The sampled data are added or averaged at predetermined intervals (steps 114, 124, 134).

  On the other hand, acceleration data of a tremor earthquake and a main earthquake are stored in advance (step 141). The acceleration data is data in the x-axis direction, the y-axis direction, and the z-axis direction as necessary.

The earthquake determination means to be described later compares the detected acceleration data with data stored in advance, and determines whether it is a microtremor earthquake or a main earthquake (step 144). The tremor and main earthquake data stored in advance are, for example, data in the x-axis direction, the y-axis direction, and the z-axis direction, similarly to the data detected by the acceleration sensor. When the earthquake determination means determines that the acceleration data is a microtremor earthquake or a main earthquake, the gas solenoid valve is shut off by the gas solenoid valve opening / closing means (step 145). The earthquake determination means continuously checks whether there is a tremor earthquake or a main earthquake.

  The gas solenoid valve opening / closing means locks the gas solenoid valve of the gas fuel device so that it does not return immediately even after the earthquake ends (step 146) when it detects a tremor or main earthquake. The normalization determination means for the gas fuel device checks the operation history of the gas fuel device and checks whether there is a gas leak from the gas fuel device (steps 147, 151, 152). When the gas fuel device normalization determination means determines that the gas fuel device is normal, the gas fuel device normalization determination means unlocks the gas solenoid valve (step 149).

  The acceleration sensor 311 in the x-axis direction, the y-axis direction, and the z-axis direction is not necessarily an all-axis acceleration sensor, and can be a required one-axis or two-axis acceleration sensor. The sampling data averaging processing means 313 averages or adds the sampled data over a certain period, and is the average value or the added data at the same time as the sampling in the tremor and main earthquake data storage means 314. The earthquake determination means 316 makes a determination by comparing the data detected by the acceleration sensor with the data stored in advance in the tremor and main earthquake data storage means 314.

  The gas electromagnetic valve locking means 318 is configured so that gas cannot be supplied to the gas fuel device even if the power is restored when the gas electromagnetic valve is closed by the gas electromagnetic valve opening / closing means 317. The gas fuel device operation history storage means 321 stores an operation history before the gas is shut off. The gas fuel device operation history storage means 321 stores, for example, whether or not gas and electricity have been supplied. The gas fuel device gas leak detection means 322 detects that the gas is not leaking due to the pressure of the gas, the combustion temperature, etc. and is normal.

The acceleration sensor also detects a single vibration 44 in addition to the tremor earthquake and the main earthquake.

  In FIG. 4B, the acceleration sensor provided in the gas fuel device also detects sudden vibrations 44 other than earthquakes. However, the sudden vibration 44 usually does not last long. Therefore, it is understood that the sudden vibration 44 does not lead to an earthquake by adding or averaging the sampling data for a predetermined period (Δx in the figure) for the value detected by the acceleration sensor.
