The battery container can be substituted.

Japanese Patent Laying-Open No. 2006-269193 (paragraph 0017, FIG. 1)

  By the way, in Japan where earthquakes occur frequently, the microcomputer meter of each household gas meter stops the gas supply when it feels a shaking with a seismic intensity of about 5 to prevent the occurrence of fire due to gas leakage. However, since the cassette-type stove used on the table uses a cassette-type gas cylinder, it is not subject to gas supply control by a microcomputer meter. The same is true for kerosene-type heaters. If the fire source of these devices is not completely extinguished and evacuated when an earthquake occurs, there is a high possibility of causing a fire.

  It would be desirable for such a device that would cause a fire to have an earthquake sensing device. However, a product combining an earthquake detection device is expensive and difficult to market. In addition, there are many households that prepare radio to collect information when an earthquake occurs, but it is impossible to quickly find the radio in the state where the earthquake actually occurred and the furniture was scattered Is also expected.

  As mentioned above, the problems that occur at the time of the earthquake have been pointed out. However, various products using batteries have recently appeared. By improving the functions of electric products using batteries, various problems including these safety issues have been introduced. The problem may be solved.

  <First Embodiment of the Invention>

  Next, a first embodiment of the present invention will be described.

FIG. 4 shows the appearance of the battery device according to the first embodiment of the present invention. The battery device 100 includes a resin battery case body 101 having an appearance size equivalent to that of a single-type battery. The battery case main body 101 has three vertically long openings 102 formed at equal intervals along the outer periphery thereof. However, only one is shown in the figure. The opening 102 is for mounting the AA batteries 103 _{1 to} 103 ₃ one by one inside the battery case body 101. In the present embodiment, each of the AA batteries 103 _{1 to} 103 ₃ is attached to the battery case main body 101 with the upper side as the side where the positive electrode terminal is arranged in the drawing.

  From the upper center of the battery case main body 101, a positive electrode terminal 104 corresponding to the positive electrode terminal of the single-type battery protrudes in a disk shape. Further, a negative electrode terminal made of a metal plate having a diameter larger than that of the positive electrode terminal 104 is embedded in the bottom portion of the battery case body 101, although not shown. A pair of external connection wires 105 and 106 are drawn out from the vicinity of the lower end of the battery case main body 101 by a predetermined length.

The bottom of the battery case body 101 has a double bottom structure of an upper bottom plate portion 108 and a lower bottom plate portion (not shown) that constitutes the original bottom portion. Therefore, a negative terminal (not shown) a portion from the opening portion 102 is disposed at the bottom of the AA batteries 103 ₁ appear as one example, the spring member of the leaf spring-shaped electrode plate 109 provided on the upper base plate 108 Is given a force in the direction of moving upward. With this force, the bottom of the AA battery 103 ₁ is pressure-bonded to the leaf spring electrode plate 109, and the positive terminal 110 protruding from the upper center of the AA battery 103 ₁ is disposed so as to be opposed thereto. The positive electrode plate that is not bonded is also pressure-bonded.

FIG. 5 shows the connection relationship of each battery when three AA batteries are attached to the battery device of the first embodiment. The positive terminals 110 _{1 to} 110 ₃ of the AA batteries 103 _{1 to} 103 ₃ are commonly connected to a common positive electrode plate 121. The positive electrode plate 121 is also electrically connected to the positive terminal 104 of the single-type battery in the battery case body 101.

On the other hand, each of the negative electrode terminal 122 ₁ to 122 ₃ AA batteries 103 ₁ to 103 ₃ are connected in common to the leaf spring-shaped electrode plate 109. The leaf spring-like electrode plate 109 has a shape in which, for example, a band-shaped portion extending in three directions of a single metal plate having a Y shape is folded upward from a predetermined position, and the folded portion is a negative electrode. The terminals 122 _{1 to} 122 ₃ are crimped one by one.

  The leaf spring electrode plate 109 is connected to one end of the external connection electric wire 105 inside the battery case main body 101. The negative electrode terminal 124 disposed at the bottom of the battery case main body 101 is connected to one end of the external connection electric wire 106 inside the battery case main body 101.

As described above, the battery device 100 according to the present embodiment has a single connection between the positive terminal 104 and the negative terminal 124 of the battery case body 101 with the other end of the pair of external connection wires 105 and 106 open. No voltage is generated by the three-type batteries 103 _{1 to} 103 ₃ , and the battery does not play a role. When the other ends of the pair of external connection wires 105 and 106 are electrically connected, the voltage of the AA batteries 103 _{1 to} 103 ₃ is between the positive terminal 104 and the negative terminal 124 of the battery case body 101. Will occur and serve as a battery.

  FIG. 6 shows a first example using the battery device of the first embodiment. Here, the battery device 100 is used for the purpose of improving the safety of the cassette-type stove 200 against an earthquake such as an earthquake. The cassette-type stove 200 obtains thermal power using a cassette-type gas cylinder (not shown). The cassette-type stove 200 is provided with a valve adjusting device 201 that supplies gas from a gas cylinder to a stove (not shown) through a valve (not shown). The valve adjusting device 201 has a built-in circuit that checks the pressure of the gas delivered from the gas cylinder and prevents the occurrence of an abnormality such as an explosion accident.

  For this reason, the valve regulator 201 is supplied with power from, for example, a battery case 203 in which a predetermined number of single-type batteries 202 are connected in series. This power source is also used to supply electric energy at the time of ignition, but is always supplied to the valve adjusting device 201 when the cassette type stove 200 is used. If the supply of power from the battery case 203 is cut off, the valve is closed from the viewpoint of ensuring safety and the supply of gas from the gas cylinder is shut off to extinguish the fire.

  In the present embodiment, the seismic sensor 210 is attached to a predetermined position such as the main body side of the cassette type stove 200. When the seismic sensor 210 senses a vibration greater than a predetermined seismic intensity, the seismic sensor 210 changes the switch 211 provided on the output side from a closed state (on) to an open state (off). Therefore, one of the single AA batteries 202 in the battery case 203 is replaced with the battery device 100 of the present embodiment, and the ends of the pair of external connection wires 105 and 106 are connected to both ends of the switch 211. Connect one by one.

  In a normal state where no vibration is generated, the switch 211 is on. Therefore, the battery case 203 is supplied with the same power as the predetermined number of single-size batteries 202 connected in series to the valve regulator 201, and the cassette-type stove 200 can be used normally.

  Assume that a vibration occurs when the cassette type stove 200 is used. Assume that the seismic sensor 210 senses this vibration and turns off the switch 211. Thereby, the path | route through which the electric current between the positive electrode terminal 104 of the battery apparatus 100 and the negative electrode terminal 124 (both refer FIG. 5) flows is cut | disconnected. As a result, the supply of power to the valve adjusting device 201 is cut off, and the fire of the cassette type stove 200 is automatically extinguished.

  FIG. 7 shows a second example in which the battery device of the first embodiment is used. In FIG. 7, the same parts as those in FIG. 6 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  In the second example, the battery device 100 is used as a radio power source that can listen to news about an earthquake when an earthquake occurs. The radio 220 includes a radio main body 221 such as a tuner (not shown) or an amplifier that outputs a broadcast of a broadcasting station selected by the tuner by sound. The radio body 221 is supplied with power from the battery case 203. In the case of this second example, the radio 220 selects an optimal broadcasting station in advance to hear information related to the earthquake, and turns on a power switch (not shown).

  The seismic sensor 210A of the second example is attached to the side of the emergency radio 220 or placed in a stable place near the radio 220, and the battery case 203 is used instead of the single battery 202. The pair of external connection wires 105 and 106 of the battery device 100 set in the battery device 100 are connected to both ends of the switch 211A. Unlike the switch 211 in the first example, the switch 211A in this example is a normally open switch, and the contact is closed when a seismic intensity exceeding a predetermined level is detected.

  Therefore, the user installs the radio 220 in a predetermined position of the house and sets the seismic sensor 210A with his / her hand in a state in which two single-size batteries 202 that can be used for a long time and the battery device 100 are set in the battery case 203. The switch 211 is turned on to turn it on. Then, power is supplied to the radio body 221 to perform tuning and volume adjustment. Thereafter, a reset button (not shown) of the seismic sensor 210A is pressed to return the switch 211 to the initial OFF state. Then, the supply of power to the radio main body 221 is cut off, and the radio 220 enters a standby state.

  The seismic sensor 210 shown in FIG. 6 or the seismic sensor 210A shown in FIG. 7 may be an electronic sensor. However, if it is a mechanical sensor, the advantage is that power is not used in an earthquake standby state. There is. As such a mechanical seismic sensor, a commercially available one or a prior art such as Japanese Patent Application Laid-Open No. 2007-93364 filed by the present applicant can be used.

  In the usage example of the battery device 100 shown in FIG. 7, even when the installation location of the emergency radio 220 is usually forgotten or the location of the radio is remembered, the furniture moves due to the occurrence of a large earthquake. Even when the location of the radio is lost, the radio 220 emits sound as the earthquake occurs. Therefore, necessary earthquake information can be acquired. Even when the resident cannot move, the sound of the radio 220 is continuously output to the outside. Therefore, the position of the house where the radio is located becomes clear from the outside, and quick rescue is possible.

  <Second Embodiment of the Invention>

  Next, a second embodiment of the present invention will be described.

  FIG. 8 shows the appearance of the battery device according to the second embodiment of the present invention. In FIG. 8, the same parts as those in FIG. 4 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  The battery device 300 according to the second embodiment includes a resin battery case body 101A having an appearance size equivalent to that of a single-type battery. The battery case main body 101A has three vertically long openings 102 formed at equal intervals along the outer periphery thereof. In one opening 102 shown in FIG. 8, a lid 301 is fixed to the upper part of the battery case main body 101 </ b> A with a screw 302. The remaining openings (not shown) do not have a lid as in the case of the openings 102 shown in FIG.

Two AA batteries 103 ₂ and 103 ₃ can be mounted inside the battery case main body 101A from two openings where the lid 301 is not present. A small hole 303 is formed in the lower portion of the lid 301, and a control line 304 passes therethrough. The control line 304 is connected to an abnormality detection unit 305 having the same shape as the AA batteries 103 ₂ and 103 ₃ . Since the abnormality detection unit 305 has the same shape as the AA battery, it can be mounted inside the battery case main body 101A in the same manner as the AA battery 1031 of the _first embodiment.

  A controller 306 is attached to the other end of the control line 304. The abnormality detection unit 305 of the present embodiment is a sensor unit that senses both abnormal vibrations such as earthquakes and abnormal temperatures. For this reason, the controller 306 includes a normal LED (Light Emitting Diode) 311 that is lit when both vibration and abnormal temperature are not detected, an abnormal LED 312 that is lit when any abnormality is detected, a reset button 313, and A sensitivity setting unit 314 is provided. The sensitivity setting unit 314 can set the sensed seismic intensity roughly in three stages by button operation.

  When any one of vibration and abnormal temperature is detected and the abnormal LED 312 is turned on, the current path between the positive terminal 104 and the negative terminal (not shown) of the battery device 300 in the shape of a single-type battery is interrupted. The reset button 313 is used to open a current path between the positive terminal 104 and the negative terminal when operated after the user confirms safety.

FIG. 9 shows the connection relation of each part in the battery device according to the second embodiment. The positive terminal 110 ₃ of the AA battery 103 ₃ is electrically connected to the positive terminal 104 corresponding to the positive terminal of the AA battery in the battery case body 101A. The positive terminal 110 ₂ of the AA battery 103 ₂ is connected to the positive terminal 110 ₁ in order to supply power to the abnormality detection unit 305.

The abnormality detection unit 305 includes first to third terminals 321, 322, and 323 on the negative electrode side. Of course, these terminals 321, 322, and 323 may be arranged at other appropriate locations on the outer surface of the abnormality detection unit 305. The first terminal 321 is connected to the negative terminal 122 ₂ of the AA battery 103 ₂ for power supply.

The second terminal 322 and the third terminal 323 are connected to both ends of a switch 331 for controlling the output in the abnormality detection unit 305. The switch 331 is kept in an on state when it is normal, and is switched to an off state when an abnormal situation occurs. The second terminal 322 is connected to the negative terminal 122 ₃ of the AA battery 103 ₃ , and the third terminal 323 is connected to the negative terminal 124 disposed at the bottom of the battery case body 101A.

As a result, the abnormality detection unit 305 is the battery case body 101A during normal not to sense the abnormality is to serve as a battery for one piece of AA batteries 103 _3. Further, the abnormality detection unit 305 senses the abnormality, open the switch 331, a battery case body 101A becomes a state where AA batteries 103 ₃ is removed, the current path is blocked.

  FIG. 10 shows an outline of the circuit configuration of the controller and the abnormality detection unit. The abnormality detection unit 305 includes a CPU (Central Processing Unit) 341 and a main control unit 343 storing a memory 342 such as a ROM (Read Only Memory) storing a control program executed by the CPU 341. The main control unit 343 is connected to each unit in the abnormality detection unit 305 via a bus 344 such as a data bus.

  Among these, the triaxial acceleration sensor 345 is a sensor that detects acceleration in the three axial directions of X, Y, and Z, and detects acceleration with small size and high accuracy by using MEMS (Micro Electro Mechanical Systems) technology. be able to. The time series data storage unit 346 stores the output of the triaxial acceleration sensor 345 in time series. The comparison unit 347 compares the three time limit data stored in the time series data storage unit 346, and determines when an earthquake of a magnitude to be detected has occurred. The temperature sensor 348 detects the internal temperature of the battery case main body 101A. A small bimetal may be used instead of the temperature sensor 348.

  The threshold value setting unit 349 sets a threshold value of the magnitude of vibration that the comparison unit 347 should detect. The threshold setting unit 349 is connected to the sensitivity setting unit 314 in the controller 306, and can adjust the sensitivity with which the user senses vibration.

  The relay excitation circuit 351 excites the relay 352 whose contact operates as the switch 331 when the comparison unit 347 detects an abnormal vibration or when the temperature sensor 348 detects a predetermined abnormal temperature. Abnormal vibrations and abnormal temperatures are often temporary, but for safety, the relay excitation circuit 351 continuously excites the relay 352 using a self-holding circuit (not shown). This excited state can be released by pressing a reset button 313 in the controller 306.

  The display control unit 353 controls lighting of the normal LED 311 and the abnormal LED 312 in the controller 306. In the present embodiment, the normal LED 311 lights in green in a state where neither abnormal vibration nor temperature is sensed. When abnormal vibration or temperature is detected and the switch 331 is turned off, the abnormal LED 312 is lit in red until the reset by the reset button 313 is performed. When the switch 331 is turned off, the current path between the positive terminal 104 and the negative terminal 124 of the battery case body 101A is interrupted as described with reference to FIG.

Therefore, for example, it is assumed that the battery case main body 101A of the second embodiment is used in the cassette type stove 200 shown in FIG. Then, it is not necessary to attach the seismic sensor 210, and when an abnormal vibration occurs or an abnormal temperature occurs, the power supply to the valve adjustment device 201 is stopped and the gas flame is extinguished. Thus although the power supply to the valve adjusting device 201 is cut off, the abnormality detection unit 305 itself is supplied with power from AA batteries 103 ₂ abnormality occurs. Therefore, notification of the occurrence of an abnormal situation due to the lighting of the abnormal LED 312 can be continuously performed.

  Moreover, according to the second embodiment, the battery case body 101A accommodates a device that senses an abnormality such as an earthquake. Therefore, a space for externally attaching the seismic sensor 210 and the seismic sensor 210A to the apparatus such as the cassette-type stove 200 shown in FIG. 6 and the radio 220 shown in FIG. 7 is unnecessary.

  Further, since the battery case main body 101A is provided with the lid 301 at the place where the abnormality detection unit 305 is attached, there is no risk of attaching the normal AA battery 103 to that place by mistake. Furthermore, the user can deal with various abnormalities by purchasing a desired type of abnormality detection unit 305 and mounting it on the battery case body 101A.

In FIG. 9, only the positive electrode terminal 110 ₃ is connected to the positive electrode terminal 104 corresponding to the positive electrode terminal of the single-type battery, but the other positive electrode terminals 110 ₁ and 110 ₁ are connected to the common positive electrode plate 121 as shown in FIG. 110 ₂ may be connected in common. In this manner, the abnormality detection unit 305 does not particularly require the use environment can be fitted with a conventional AA batteries 103 ₁ in a position for mounting the abnormality detection unit 305. Then, the negative electrode terminal 122 ₁ of AA batteries 103 ₁ is connected to the negative terminal 124 of the battery case body 101A, resulting in the negative electrode terminal 122 ₁ to 122 ₃ are connected to the negative electrode terminal 124. That is, by attaching the conventional AA batteries 103 ₁ can easily switch it to the form of connection three AA batteries 103 ₁ to 103 ₃ are connected in parallel.

  In the first and second embodiments described above, the battery case body 101 is the size of an AA battery, and three AA batteries or an abnormality detection unit having the same external dimensions as the AA battery is accommodated therein. However, it is natural that the battery case body of a predetermined size may accommodate a battery of a smaller size or an abnormality detection unit having the same external dimensions. The same applies to the button battery.

  Further, the number of batteries housed in one abnormality detection unit or the number of abnormality detection units having the same external dimensions is not limited to the example described in the embodiment of the present invention. For example, when the battery case body 101 is the size of an AA battery, the AA battery or anomaly detection units having the same external dimensions as that of the AA battery are not limited to a total of three. There may be two or four in total.

  Further, the abnormality detection unit does not need to have the same shape as the battery unless consideration is given to the compatibility with other batteries. For example, the abnormality detection unit may have a quadrangular prism shape, or may be incorporated into the bottom of the abnormality detection unit or a gap portion when each battery is mounted. In this way, by using the empty space when the battery is accommodated, the space allocated to the abnormality detection unit can be allocated to the other battery accommodating space.

  Furthermore, in the first and second embodiments, the cylindrical battery case main body is shown, but the battery case main body has various shapes depending on the shape of each battery and the arrangement (series or parallel) of the batteries. It can be. Moreover, the individual batteries accommodated in one battery case main body do not have to be equal in size.

In the second embodiment, the power source of the abnormality detection unit is obtained from the battery attached to the battery case body. However, the present invention is not limited to this. If houses a built-in button battery for example, the abnormality detection unit 305, need not be used as AA batteries 103 ₂ source of power shown in FIG.

  Further, in the second embodiment, the switch that becomes the contact point of the relay is arranged in the abnormality detection unit, but it may be arranged in a predetermined place of the battery case main body.
