It can be rotated to any angle.

In addition, the outer diameter of the heater stopper located at the top of the mounting bracket and fixed to the end of the sheathed heater is υ larger than the outer diameter of the mounting bracket and the through hole, and when normally installed, the heater stopper is transparent. The hole is closed to prevent foreign matter from entering.

Furthermore, the mounting bracket is made of a metal with good thermal conductivity to enhance heat diffusion and lower the temperature of the sealed portion of the sheathed heater. Furthermore, a spring, which is a biasing member, is interposed between the through hole at the top of the body and the mounting bracket to improve the feel when the heater unit is rotated up and down.

The outer diameter of the mounting bracket 18 is approximately the same as the diameter of the through hole 17,
Moreover, the diameter of the lower part is made larger than the diameter of the through-hole part 17, thereby making the entire heater unit 13 vertically movable and preventing it from being pulled out. Also, on the back side of the heater stopper 16, a grounding metal fitting (
(not shown) is attached.

A box-shaped back plate 19 is fixedly connected to the back surface of the body 11. A lead wire 2o is connected to the sheathed heater 14, and this lead wire 20 passes through the inside of the back plate 19 and is led out to the outside, and is connected to the control section 21.
is electrically coupled to.

Further, the entire container body is fixed to the table surface 22 by being clamped and crimped to the table surface 22 with the locking fittings 23 via the packing 12.

The operation of the above configuration will be explained next.

In other words, during cooking, the boiled liquid is absorbed into the body 11.
Since it is stored in the concave portion 11a of the container, it does not fall into the inside of the back plate 19, and this storage state can be easily confirmed from the outside. In addition, when cleaning the boiled liquid stored in the concave portion 111L, the entire heater unit 13 is connected to the through hole portion 17 of the body 11 and the mounting bracket 1.
8 is configured to allow one vertical sliding movement and to prevent removal, so the concave portion 11a of the body 11 can be cleaned with a simple operation, thereby reducing the number of parts to be cleaned. In conjunction with this, it is possible to improve the efficiency of processing and time.

In addition, since there is a heater attachment part in the rear corner of the container, it does not get in the way during normal cooking.
This allows for improved operability.

In addition to this, the temperature of the sealing part (final terminal part) of the sheathed heater 14 is preferably lower from the viewpoint of insulation properties and sealing material cost. Combined with the simplicity of the entire vessel, it produces good effects. Also, attach the mounting part to body 1.
1, it is possible to prevent as much as possible the boiling liquid that overflows from the concave portion 11 & of the body 11 from entering, and the heater stopper 16 always closes the through hole 17. Because of this, splashing of boiled soup,
It is possible to prevent foreign matter from entering, thereby making it possible to prevent electrical failure and to prevent the inside of the back plate 19 from becoming dirty.

In addition, since the mounting bracket 18 is made of metal with good thermal conductivity, heat conduction and heat diffusion are smooth, and it plays the role of lowering the temperature of the sealing part of the sheathed heater 14, and has insulation resistance. It is effective in ensuring that

As a result, it is possible to obtain an electric stove that has a small number of parts, is easy to clean, and is inexpensive.

In addition, in FIGS. 1 and 3, the heater unit 13
The heater support fitting 15, which is a component of the sheathed heater 14, is radial from the spiral center of the sheathed heater 14 and is made of sheet metal. If the inner diameters of the concave portions 11a of the body 1 are set to be approximately the same, the entire heater unit 13 will not rotate during normal use.
The heater unit 13 has a simple configuration that serves to minimize the external force applied to the mounting part provided at the top of the heater unit 13.
The durability of the material can be guaranteed.

FIG. 4 shows a second embodiment of the present invention, in which an annular guard 24 is attached to the outermost diameter portion of the heater support fitting 15.

The annular guard 24 may be made of a round wire rod or a sheet metal (in the embodiment, a round wire rod is used), and the guard 24 is longer than the outer diameter of the spiral portion of the sheathed heater 14, and extends downward from the top surface of the spiral portion. The heater support fitting 15 is fixedly connected to the heater support fitting 15 at a certain position. In addition, the mounting method is that it can be attached to the tip of the heater support fitting 15 by engaging it, and if the guard 24 is to be made removable, it can be fitted by applying the biasing spring force of the guard 24. It is sufficient to do so.

In the first embodiment shown in FIGS. 1 to 3 above, the heater support fittings 15 are configured radially, thereby preventing a decrease in mechanical strength due to an external force in the radial direction, thereby eliminating a sense of anxiety. In addition, although the sheathed heater 14 is generally in a red-hot state during cooking, it is also possible to prevent the danger of accidentally touching the heat generating part directly.

FIG. 5 shows a third embodiment of the present invention, in which the through hole 17 of the body 11 is formed in a D shape, and the outer diameter part of the mounting bracket 18 is also formed in a D shape. This is what I did. The lower part of the mounting bracket 18 is set to be larger than the diameter of the through hole 1T, and the lower end is provided with a flange part 18&, which is made of a metal with good thermal conductivity as described above.

Note that the D shape is constructed by pouring an appropriate amount downward, and the portion between the above-mentioned flange 1B& is shaped so that it can be rotated at any angle within the through hole 17 from the lower position. It is configured. As a result, the entire heater unit 13 is
The heater unit 13 cannot be rotated until it is pulled up a certain distance, and when it is pulled up any further, it can be rotated to any desired angle.
It is possible to prevent the entire body from rotating and moving, thereby eliminating the feeling of anxiety.

Further, when using this configuration, the rotation angle can be arbitrarily set in either the clockwise or counterclockwise direction, depending on the direction setting of the D shape.

In the above embodiment, the outer ring part of the sheathed heater 14 can be rotated to the position of the side part of the square shape, and when cleaning, the user can pull up the heater unit 1-1:35 and rotate it. Therefore, even if electricity is accidentally turned on, it is possible to prevent an abnormal temperature rise on the wall surface of the kitchen unit. In this way, it is possible to provide an electric stove that is easy to clean and safe.

Furthermore, as shown in FIG. By holding the heater unit 13 in place and creating a structure in which a biasing force is always exerted to push the heater unit 13 downward, it is possible to prevent vertical movement caused by external vibrations. It provides a clean feel during one vertical sliding turn, and can add additional functions with simple components.

FIG. 6 shows a fourth embodiment of the present invention, in which an opening 26 is provided in the center of the concave portion 11a of the body 11, and a dish-shaped plate is provided above the opening 26. The soup receiver is on plate 2
7 is detachably provided. In this case, body 1
1 is made of a stainless steel plate such as 5US430° or 5US304, and the saucepan 27 is made of a steel plate which has been subjected to a hollow treatment. -Sheath heater 1 for boat fishing
In the case of an earthenware pot or iron frying pan with a large bottom diameter, the temperature of the part 11 of the body directly below the heat generating part 4 increases, causing thermal discoloration. Therefore, it was necessary to ensure a distance between the concave portion 11a at the center of the body 11 and the sheathed heater 14 to prevent discoloration. In this embodiment, the hollow-treated soup tray is equipped with a plate 27, so that it is possible to check the accumulation of boiled water, improve cleaning efficiency, and prevent thermal discoloration of the stainless steel body 11. The distance between the sheathed heater 14 and the soup receiver can be maintained at an appropriate distance from the bottom of the dish 27, and the vessel can be kept simple.

FIG. 7 shows a sixth embodiment of the present invention, in which both ends of the spiral shape of the sheathed heater 14 are configured to extend υ from the outer ring of the spiral portion, In conventionally known spiral-shaped sheathed heaters, the end portion from the inner circumferential portion of the spiral is bent downward, and the end portion passes below the spiral portion and extends in the horizontal direction, and in this case,
Due to processing technology, it is necessary to keep a certain distance from the bottom of the spiral part, and therefore, the body 11 and the soup receiver corresponding to that part require a certain design consideration for the plate 2. However, the present invention In this embodiment, the electric stove can extend on the same plane as the spiral part of the sheathed heater 14, and by bending both of the extended ends vertically downward, the cleaning level is high and the number of parts is small. It is possible to obtain it.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
The juice that boils over during cooking is stored in the concave shape in the center of the body, so you can observe the storage status from the outside and prevent it from dripping into the back plate. The heater unit is located at the top of the body, and the heater stopper is fixed to the end of the sheathed heater, so the action of the heater stopper prevents liquids and foreign matter from entering the through-holes of the body. Moreover, because the heater unit can be moved up and down by the action of the mounting bracket, the level of cleaning is high, such as easy removal of boiled liquid, and the number of times the heater unit can be moved is reduced. This makes it possible to obtain an electric stove that can be operated easily.
