危険感を持たれている。Conventional technology Electric stoves are equipped with a heat generating device such as a quartz tube heater.
If the heater falls to the floor while the heater is still energized, the floor surface will be scorched, and in the worst case, it will lead to a fire. Therefore, conventionally, a fall OFF switch is provided to stop the power supply to the heater in the event of a fall. Therefore, in the event of a fall, the heater will stop energizing and there is no risk of fire, but in recent years, vertical stoves with vertically arranged quartz tube heaters have become more popular, and their main bodies are long and long. There is a sense of danger in itself because it is easy to fall over.
以下に従来の電気ストーブについて説明する。A conventional electric stove will be explained below.

接点を開くようになっている。FIG. 4 is a cross-sectional view of a conventional electric stove in which a quartz tube heater is arranged vertically.A fall-off switch 3 is housed in a stand 2 that supports the main body 1, and when the product is in use, a push rod 4 is The movable contact plate 5 of the fall OFF switch is pressed to close the contact of the fall OFF switch 3. In the event of a fall, the push rod 4 will no longer be pushed up from the floor, so the fall OFF switch 3 will be activated by the spring force of the movable contact plate 5.
It is designed to open the contacts.
発明が解決しようとする課題
しかしながら上記従来の構成では、製品が転倒するとき

大へのコスト増などの課題を有していた。Problems to be Solved by the Invention However, in the above conventional configuration, a switch is activated only when the product falls over, and a detachable cord is used so that the power cord comes off when the product is hooked by foot. There are ways to prevent this from happening, but since the stove is a product with a relatively large current capacity, there are issues such as decreased reliability due to the increased number of connections on the electric circuit, and increased costs due to the increased number of parts. had.
本発明は上記従来の課題を解決するもので、製品を転倒

定している。As shown in the figure, a quartz tube heater 12 and a reflection plate 13 having a parabolic cross section with the center of the quartz tube heater 12 as a focal point are provided at the front openings of the vertically long main body cases 7 and 11. A connector 16 for a power cord 16 is installed behind the stand 14 that supports the main body case 711. Here, the body-side plug 17 of the power cord 15 has a magnetic material 18 provided at its tip, and the conductive portion 1 of the plug 17 is brought into close contact with a metal piece 21 provided at the center of the body-side cradle 20.
9 and the conductive portion 22 of the pedestal 20 are connected. Plug 17
The outer shape of the stepped portion 3 that comes into contact with the outer frame 23 of the pedestal 20 is
It has 0. The outer frame 23 has a compression spring 2 inside the main body.
It is pressed from behind at 4 and is attached movably in the insertion direction of the plug 1. A hole 26 is provided below the outer frame 23.
An inverted U-shaped convex portion 27 of the leaf spring 26 is provided at a position where the plug 17 is engaged when inserted into the pedestal 2o. The push rod 29 is still held by the stand bottom plate 28 so as to be able to move up and down. are held together, and the outer frame 23 is fixed against the compression spring 24.
以上のように構成された本実施例の電気ストプについて
以下その動作を説明する。The operation of the electricity stopper of this embodiment configured as described above will be explained below.

バネ２６の凸起２７が外枠２３の穴２５からはずれる。First, when the body switch (not shown) is turned on, the quartz tube heater 12 is energized, and the heat emitted from it is directly or
It is reflected by the reflector 13 and radiates forward. If you accidentally trip over the power cord 16 during use, the plug 17 will not fall over because the magnetizing force between the plug 17 and the cradle 20 is smaller than the body's own weight. It will come off the main body. Also, if you accidentally knock down the main body directly, the push rod 29 loses its pushing force from the floor, so it moves downward under the pushing force of the leaf spring 26, and the protrusion 27 of the leaf spring 26 pushes against the outer frame 26. It comes off from hole 25.
そして圧縮バネ２４の反発力により外枠２３が外方へ押

電するという危険性が解消される。As described above, according to this embodiment, a removable plug is provided at the connection part of the power cord on the main body side, and the outer frame of the cradle is movable, and the protruding force of the outer frame is regulated by the force of the push rod. This enables the two parts of the conventional detachable plug and tipping OFF switch, which opens and closes in the event of a tipping over, to be performed in one part, reducing production costs and reducing reliability due to an increase in the number of electrical connections. can reduce the risk of falling. Furthermore, when falling, the quartz tube often breaks, and in this case, the internal conductor is exposed, and in the worst case, live parts are exposed, creating a risk of electric shock. According to the company, both sides of the power supply wire can be shut off, eliminating the risk of electric shock when returning the product to its original position.

ぐれた電気ストーブを実現できるものである。Effects of the Invention The present invention provides a removable plug at the connection part of the power cord on the main body side, makes the outer frame of the cradle movable, and regulates the protruding force of the outer frame by the push-up force from the floor surface of the push rod. As a result, even if the power cord is accidentally tripped over during use, the plug will easily come off, reducing the risk of the product falling over, and if the main unit is directly knocked over, the outer frame The plug is forcibly removed by the pushing force,
Energization to the quartz tube heater can be stopped. In addition, the conventional cord connection part and 2 contacts of the OFF switch in the event of a fall,
By making two parts into one part of the connector, the number of contacts on the electric circuit is reduced, reliability is improved, and an excellent electric stove can be realized that has the effect of reducing production costs. It is something.
