Description

MPU with power supply terminal {MAGNETIC POWER UNIT HAVING POWER SUPPLY TERMINAL}

The present invention relates to MPU, and more particularly to MPP configured to operate the gas inlet opening valve before the thermocouple is operated by receiving power from the outside.

Gas leakage automatic shutoff device used in home gas stove can prevent gas explosion by preventing gas leakage in case of fire extinguishing due to unexpected situation such as overflow during food cooking. As the device configured, the sensing of the extinguishing is made by a thermocouple, and comprises a solenoid valve configured to block the gas flow in accordance with the sensing of the extinguishing by the thermocouple. The thermocouple is composed of a closed circuit by joining two kinds of metal wires having different materials, and is configured according to a Seebeck effect that a thermoelectric power is generated in the closed circuit when a temperature difference is generated at the joined contact.

A typical domestic gas stove generates thermoelectric power by heating an element of a thermocouple provided in a gas leakage auto shutoff device by igniting a gas discharged to a pilot burner with a spark plug, and the current caused by the thermoelectric power is applied to the gas leakage auto shutoff device. Flowing through the coil provided in the to generate the adsorption electron force in the magnetic body, by maintaining the state in which the valve to control the flow of the gas by the adsorption electron force is configured to burn the gas. In addition, when combustion is stopped due to an unexpected external factor such as strong wind or food overflow during the combustion process as described above, the thermoelectric power generated by heating of the thermocouple element is dissipated, and thus is generated in the magnetic body. Since the adsorption electromagnetic force is also dissipated, the valve is automatically closed to block the flow of gas.

Hereinafter, a conventional gas leakage automatic shutoff apparatus will be described with reference to the accompanying drawings.

1 is a cross-sectional view showing the internal configuration of a conventional gas leakage automatic shutoff device.

As shown in FIG. 1, a conventional automatic gas leakage blocking device is moved downward when a thermoelectric power due to a Seebeck effect is applied to a coil 16 to a magnetic body 14 provided inside a housing 12. When the contact and the thermoelectric power is extinguished, the MPU assembly part 10 including the valve 20 moved upward again by the restoring force of the spring 22 and the element part 50 formed by protruding the lower end part in a needle shape. And an cable 40 connecting the MPU assembly unit 10 and the element unit 50, and an element cable 42 coupled to one end of the element unit 50. The coupling between the MPU assembly unit 10 and the cable 40 is such that a connection terminal 30 coupled to one end of the cable 40 is inserted into the socket pin terminal 18 of the MPU assembly unit 10. Configured to fit.

At this time, when the valve 20 moves downward to contact the magnetic body 14, the gas inlet is opened. When the valve 20 moves upward and spaced apart from the magnetic body 14, the gas inlet is opened by the valve 20. I get stuck.

In addition, the coupling portion of the circular terminal 30 and the socket pin terminal 18 of the automatic gas leakage automatic shutoff device configured as described above is generally caused by corrosion caused by moisture generated due to the nature of the kitchen using a lot of water. It is easy to cover the moisture-proof cap 44 is formed of a vinyl to protect the coupling portion is configured to prevent conductivity degradation due to corrosion.

However, when using the conventional gas leakage automatic shutoff device as described above, the user until the element portion 50 is heated to generate a thermoelectric power enough to maintain the state in which the valve 20 is in contact with the magnetic body 14 There was an inconvenience that you have to hold down the ignition switch.

In addition, the user cannot know whether or not the thermoelectric power is generated to keep the valve 20 in contact with the magnetic body 14. Therefore, when the user releases the operation of the ignition switch before the thermoelectric power is generated, the valve 20 moves upward by the elastic force of the spring 22 to block the gas inlet so that the user must operate the ignition switch repeatedly. There was a problem.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an MP oil having a structure that can open the gas inlet even if the ignition switch is not pressed for a long time.

MP oil according to the present invention for solving the above problems, the electromagnet including a magnetic body wound around the first coil and the second coil, and a portion corresponding to the magnetic body is made of a magnetic material and in contact with the magnetic body And a valve configured to be operable to be spaced apart. The magnetic body has a portion corresponding to the valve divided into two or more pillars, the first coil and the second coil is wound on at least one pillar.

In this case, MPU according to the present invention further includes a first pin terminal connected to the first coil and a second pin terminal connected to the second coil. In addition, it is preferable to further include an elastic means for applying an elastic force to the valve in a direction away from the magnetic body.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the MP oil and gas leakage automatic shutoff device including the same according to the present invention.

2 is a cross-sectional view of the MP oil according to the present invention, Figure 3 is a bottom view of MP oil according to the present invention.

MPU 100 according to the present invention for solving the above problems, a pair of magnetic bodies 110 and a first coil wound on the outer surface of the pair of magnetic bodies 110 spaced a predetermined interval ( 122, the second coil 124 wound around the magnetic body 110 on one side, and is positioned in the upper side of the magnetic body 110 is configured to the vertical movement to be in contact with or spaced apart from the magnetic body 110 The valve 130, a spring 140 for applying an elastic force to the valve 130 in a direction away from the magnetic body 110, and a first pin terminal 152 connected to the first coil 122 and protruding to the bottom surface. ), And a second pin terminal 154 connected to the second coil 124 and protruding to the bottom surface.

In this case, the structure in which the coils 122 and 124 are wound on the magnetic body 110 is a structure of an electromagnet that generates magnetic force in the magnetic body 110 when a current is applied to the coils 122 and 124. In the present embodiment, the magnetic body 110 is provided as a pair, but the number and shape of the magnetic body 110 is not limited and may be freely changed according to a user's selection. For example, the first coil 122 and the second coil 124 may be wound on one magnetic body 110, and two or more pillars may be formed on the magnetic body 110 corresponding to the valve 130. After the first coil 122 and the second coil 124 may be wound around each pillar.

Since the valve 130 is a portion corresponding to the magnetic body 110, that is, the bottom surface is made of a magnetic material, when the magnetic force is generated in the magnetic body 110, the bottom surface is moved downward to contact the upper surface of the magnetic body 110. When the magnetic force generated in the magnetic body 110 is lost, it is moved upwardly to be spaced apart from the magnetic body 110 by the elastic force of the spring 140. At this time, since the upper surface of the valve 130 is configured to open and close the gas inlet (not shown), when the bottom surface moves downward to contact the upper surface of the magnetic body 110, the gas inlet is opened and spaced apart from the magnetic body 110. If it is moved upward, close the gas inlet.

Thus, since the structure of opening and closing the gas inlet by vertically reciprocating the valve 130 is the same as the conventional MP oil 100, a detailed description thereof will be omitted.

When power is applied through the first pin terminal 152, a current flows in the first coil 122 to generate a magnetic force in the magnetic body 110, and the valve 130 is caused by the magnetic force of the magnetic body 110. The bottom surface is in close contact with the upper surface of the magnetic body 110 by moving downward. In addition, even when power is applied through the second pin terminal 154, current flows in the second coil 124 to generate magnetic force in the magnetic body 110. The upper surface of the magnetic body 110 is in close contact.

At this time, when the current flowing to the first coil 122 or the second coil 124 is cut off, the magnetic body 110 loses the magnetic force, the valve 130 is moved upward by the elasticity of the spring 140. In the embodiment shown in FIG. 2, the coil type spring 140 is used as a means for applying elasticity to the valve 130 in a direction away from the magnetic body 110. The present invention is not limited thereto and may be variously changed according to a user's selection.

Accordingly, as the element part 200 is heated, thermal power is generated, and thus, a magnetic force pulling the valve 130 is formed in the magnetic body 110.

In addition, even when power is applied from the power supply unit 300 to the second coil 124 through the second cable 430, a magnetic force that pulls the valve 130 is formed in the magnetic body 110. In this case, when the ignition switch (not shown) is operated, the power supply unit 300 applies power to the second coil 124 so that a magnetic force that pulls the valve 130 to the magnetic body 110 is generated, and thermal power is generated. When the magnetic force is formed in the magnetic to maintain the state in which the valve 130 is in contact with the magnetic body 110 is configured to block the application of power to the second coil (124). That is, when the operation of the ignition switch is started, the power is applied from the power supply unit 300 to the second coil 124, the valve 130 is attached to the magnetic by the magnetic force formed in the magnetic, and after the thermoelectric power is generated The thermoelectric power is applied to the valve 130 is attached to the magnetic by the magnetic force formed in the magnetic.
