Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electric stove that performs radiant heating using the heat generated by a quartz tube heater installed in the electric stove body.

Conventional configurations and their problems Conventional vertical electric stoves, mainly sold in the United States, have insufficient safety models, as they do not take into account the possibility of the quartz tube heater cracking when it falls over. Some models are equipped with cushions for safety reasons, but in models with cushions,
In order for this cushion to perform the function of preventing the quartz tube heater from cracking when it falls over, it is necessary to install a cushion made of wire around the electric stove body at a distance from the outer periphery of the electric stove body. The size of the electric stove body is larger than the model, and as a result, the volume when packed is larger due to the cushion, which is a factor in increasing costs.

Also, in order to avoid increasing the volume during packaging, the cushion is made into a unit, and this unitized cushion is packaged with the electric stove itself, and when the electric stove is used, the cushion unit is fixed to the electric stove body with screws. However, in this case, it is necessary to use a tool such as a screwdriver to attach the cushion unit before using the electric stove, which makes it extremely difficult to use. In this case, even if the cushion is not attached, there will be no change in the performance of the electric heater as long as it is used under normal conditions. In many cases, electric heaters are used without being installed, and in that case, it is impossible to prevent the quartz tube heater from cracking.
It was not possible to sufficiently ensure safety.

Purpose of the invention In view of the above-mentioned conventional problems, the purpose of the present invention is to provide an electric stove with a structure that does not increase the volume when packaged and also ensures that the quartz tube heater is prevented from cracking when it falls over. shall be.

Structure of the Invention In order to achieve the above object, the present invention provides an insertion hole and a locking part on both sides of the electric stove body, and connects the quartz tube heater to the electric stove body by making the insertion hole and the locking part face at least one locking part on the side of the electric stove body. A switch is provided to turn the electricity on and off, and both ends of a cushion material made of an elastic wire are inserted into the insertion hole so as to protrude outward from the outer periphery of the electric stove body. A portion of the cushion material is locked in the locking portion to hold the cushion material in that position, and the switch is pressed by the end insertion portion of the cushion material to turn on. According to this configuration, no tools are required. The cushion material can be easily attached to the electric stove body using its elasticity, and the quartz tube heater cannot be energized unless the cushion material is attached to the electric stove body, which prevents the electric stove body from tipping over. Since the cushion material sometimes comes into contact with the floor and absorbs the impact, it is possible to reliably prevent the quartz tube heater installed inside the electric stove from cracking.
In addition, during packaging, the cushion material can be easily removed from the electric stove body without tools, making it possible to package this cushion material with the electric stove body.As a result, the packaging volume is reduced to the specification without the cushion. Since the same size is sufficient, the cost does not increase.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. Fig. 1 shows a vertical electric stove according to an embodiment of the present invention, and 1 is an electric stove body with an opening at the front. A front reflector 2 with a parabolic cross section, and this front reflector 2
upper and lower reflectors 3 and 4 installed above and below the
A quartz tube heater 5 is provided on the front side of the front reflector 2 and vertically attached to the upper and lower reflectors 3 and 4. The quartz tube heater 5 has a coil-shaped heating element inside and is constructed by insulating the outside with a quartz tube. 6 is a guard attached to the front opening of the electric stove body 1, and this guard 6
is provided to prevent contact with the quartz tube heater 5. 7 is the electric stove body 1
8 is a power supply/capacity selector switch provided at the lower front of the electric stove body 1; one end of this switch 8 is connected to the power cord 9, and the other end is connected to the quartz tube heater 5. has been done.

FIG. 2 shows the related structure of the cushion material 10 that is detachably attached to the electric stove body 1 and the electric stove body 1. At the upper side of both sides of the electric stove body 1, mounting brackets 11 are installed with screws 1.
The mounting fitting 11 is provided with an insertion hole 13, a locking portion 14, and a notch 15 for locking a portion of the cushion material 10 with the locking portion 14. Further, the cushion material 10 is made of an elastic wire material, and its outer periphery is configured to be large so as to protrude outward from the outer periphery of the electric stove main body 1, and the side located on the back side of the electric stove main body 1 is opened, and insertion portions 16 are formed at both ends thereof to be inserted into the insertion holes 13 of the mounting bracket 11. Reference numeral 17 denotes a protrusion that is integrally formed close to the locking portion 14 of the mounting fitting 11 to prevent it from coming off, and 18 is a handle portion attached to the back side of the electric stove body 1.

Fig. 3 shows the cushion material 10 attached to the mounting bracket 11 of the electric stove body 1. When attaching the cushion material 10 to the mounting bracket 11, first use the elasticity of the cushion material 10 to slightly tighten the cushion material 10. In the expanded state, insert the insertion portions 16 formed at both ends of the cushion material 10 into the insertion holes 1 of the mounting fittings 11.
3, then insert a part of the cushion material 10 through the lower end opening of the notch 15, and
to be locked. This holds the cushion material 10 in position as shown in FIG. In this way, the cushion material 10 can be easily attached to the electric stove body 1 without any tools.

Further, as shown in FIGS. 4 and 5, the lever 23 of the micro switch 22 provided on the electric stove body 1 is arranged to face the insertion hole 13 of the mounting bracket 11, and When the insertion part 16 is inserted into the insertion hole 13 of the mounting bracket 11, the lever 23 of the micro switch 22 is pushed by the tip of the insertion part 16, and the micro switch 22 shown in the electrical circuit diagram of FIG. 6 is turned on. , and the quartz tube heater 5 can be energized.This makes it impossible to energize the quartz tube heater 5 unless the cushion material 10 is attached to the electric stove body 1. Therefore, even in normal use, the user cannot is a safety device in the event of a fall, i.e. cushion material 1
0 cannot be used unless it is attached to the electric stove body 1. As a result, in the event of a fall, the cushion material 10 made of elastic wire hits the floor 21 and absorbs the impact, as shown in FIG. Since the quartz tube heater 5 is absorbed by the water, the quartz tube heater 5 is not cracked or damaged, and safety is ensured.

Effects of the invention As described above, according to the invention, the cushion material can be attached to the electric stove body without any tools.
The cushion material can be easily attached to the electric stove body using its elasticity, and the quartz tube heater cannot be energized unless the cushion material is attached to the electric stove body, so even in normal use, When the electric stove falls over, the cushion material comes into contact with the floor and absorbs the impact, ensuring that the quartz tube heater installed inside the electric stove is prevented from cracking, and can be packed without the need for tools. Since the cushion material can be easily removed from the electric stove body, it is possible to package this cushion material with the electric stove body, and as a result, the packaging volume only needs to be the same size as the specification without cushion. This has the advantage of not increasing costs.
