[Prior art]

 Electrical appliances require outlets and are widely used in various places. Outlet that is used by fixing it in an embedded box on a wall or column, a moving outlet (table tap) that uses a slightly extended cord by changing the position, and the number of electrical appliances used by increasing the receptacle for plugs Various types of outlets have been proposed depending on the application, such as outlets for increasing the number of outlets. The usage rules are specified on the device itself so that each outlet will not be used unduly. When an excessive current is used, the power supply is equipped with a breaker, fuse, etc., ensuring safety against excessive current.

[0003]

[Problems to be solved by the device]

 If the outlet has increased electrical resistance due to rust, discharge, etc., dust or moisture has penetrated, or power is being used beyond the standard of the outlet, or if the room temperature rises above a certain level, the outlet will overheat and the outlet circuit There is a case that dust or paper dust attached to the etc. ignites, or the outlet itself burns, leading to a fire. This is because the exothermic temperature exceeded the flash point of the material around the outlet and the ignition point of the outlet or the accessory code due to the excess of the power consumption. Conventionally, there is no safety device in the power supply itself, and safety is ensured in the breaker and fuse of the power supply, so even if the current value of the outlet standard is exceeded, the capacity of the breaker and fuse of the power supply must be exceeded. No trouble will occur. However, installing a breaker or fuse in the outlet not only makes it inconvenient to use the computers and world processors that have been widely used in recent years, but also increases the electrical resistance due to rust and discharge in the outlet. I cannot perceive changes. For this reason, when the outlet becomes overheated and a dangerous state approaches, it is necessary to prevent the fire by issuing an alarm by sound or light. We have made slight improvements to the outlets that have been used so far, and at a reasonable price, make it easy for people with children with eyes or ears, children, and infants who have a visual or ear impairment to know what the alarm is and to properly identify the fire. There is a need for something that predicts and strongly appeals that the danger is near. Also, the danger may be imminent and the computer or world processor may turn off suddenly while you are working on it, or you may hear unpleasant noises while watching a movie or art, or during a lecture or important meeting. If you do, the effect will be halved. There is a demand for outlets that allow accurate determination of how to use and manage electrical appliances, and have few obstacles that anyone can use with peace of mind anytime, anywhere.

The present invention was devised based on the above requirements, and predicts overheating of an outlet in advance, prevents various harmful effects due to overheating, and shuts off the circuit when the prediction is overlooked.

[Embodiment of device]

 Hereinafter, an embodiment of an outlet overheat alarm protector 11 according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a basic configuration diagram of the present invention. To explain with the configuration diagram of Fig. 1, put the voltage applied to the outlet on the temperature sensor 3B, plug several electric appliances into the plug insertion port 2, and use the electric power of the electric appliances. Depending on the conditions, electrical resistance is generated between the plug and the metal of the plug insertion port 2, and heat is applied. Dust, water, room temperature, and various conditions are added to it to cause overheating. When the outlet itself becomes overheated, the temperature sensor 3B detects this and turns on the circuit. When the circuit of the temperature sensor 3B is turned on, a current flows through the alarm sound generator 4 and the alarm lamp 6 to generate an alarm by sound and light. Sounds are harmful to the environment if they are listening to movies, music, etc., or during important speeches such as lectures. Therefore, the alarm sound stop button 5 that can temporarily stop only the sound is installed. If the alarm cannot be corrected and overheating progresses, the temperature sensor 3A, which is one of the circuit breaking means, includes the outlet overheat alarm protector 11 and the electrical appliances engaged with the plug insertion port 2. The circuit is cut so that safety can be ensured.

This is a form in which the outlet overheat alarm protector 11 of the present invention is embedded in one of them. The electricity received in the outlet is connected to the outlet overheat alarm protector 11 of the present invention as a power source, and is connected to the terminal of the plug insertion port 2 via the outlet overheat alarm protector 11. Therefore, the temperature sensor 3B is placed with a potential applied thereto, and the circuit is normally open so that no current flows. When the outlet overheats and the temperature sensor 3B operates, the circuit closes and a current flows, so that the alarm sound generator 4 and the alarm lamp 6 also operate to emit sound or light. Also, by pressing the alarm sound stop button 5, only the sound can be temporarily stopped. Furthermore, even if the alarm continues to be issued, the entire electric circuit is automatically cut off when the temperature reaches the limit temperature when a person is absent and cannot be treated. The temperature sensor 3A, which automatically restores the entire electric circuit when the temperature of the overheated outlet is lowered, is provided for safe use. Furthermore, a facial expression projection plate 12 is formed on the surface of the outlet overheat alarm protector 11 so that young children can also be interested.

FIG. 4 and FIG. 5 show an outlet overheat alarm protector 11 of the present invention integrated in a moving outlet (tabletap). By using one moving outlet, overheating is prevented. Not only can it function as an alarm protector, but it can also be plugged into several electric appliances by changing the position or increasing the number of plug insertion ports 2. Moreover, it is a mobile outlet with a built-in overheat alarm protector that is simple and can be used with confidence. 4 and 5 show that the power is supplied from the outside by the power cord 14 and the electric potential is applied to the temperature sensor 3B. When the outlet is overheated, the temperature sensor 3B is activated and the alarm sound generator 4 and the alarm lamp 6 are electrically activated. Sends a sound and emits a light to alert you. When the sound is unnecessary due to the environment of use such as a room, the alarm sound stop button 5 can be pressed to temporarily stop the sound so that it can surpass the situation. Since the metal plate of the plug insertion port 2 and the power cord 14 generate excessive heat, the metal plate of the plug insertion port 2 is extended to approach the temperature sensor 3B, and further, the temperature sensor is used. When overheating reaches the limit due to 3A, all circuits are automatically turned off in consideration of the case where no one receives an alarm, and a restoration device is added to enhance safety. In addition, the facial expression projection plate 12 is formed on the surface of the context overheat alarm preventer 11 of the present invention in order to make children and young children interested.

FIGS. 6 and 7 show that the outlet overheat alarm protector 11 of the present invention is inserted into the ready-made transfer outlet 17 with the rotary insertion plug 16, the power source is installed from the plug 11, and When the transfer outlet 17 overheats, the heat is transferred from the rotary insertion plug 16, the cord 18 of the ready-made transfer outlet, the alarm device storage box 13, etc. This is the same as the outlet overheat alarm protector 11 of the above. In order to give an alarm by this method, it is necessary to improve heat conduction. Therefore, increase the cross-sectional area of the plug contact plate and heat conduction plate 15 or attach the cord 18 of the ready-made transfer outlet to the temperature sensor. , The alarm leg storage box 13 is also fitted with a stabilizing leg 19 (folding the leg when attaching to a wall-mounted outlet) in order to firmly attach it. This is an outlet overheat alarm protector that is designed so that the temperature sensor 3A, 3B can be set at a lower limit temperature of about 20 to 30% because the distance between heat conducting parts is a little longer and that it can be used with peace of mind.
