Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a water heater, and more specifically to an immersion type water heater for boiling a small amount of water.

[Conventional technology]

BACKGROUND ART A plunge-type water heater using a rod-shaped heater has conventionally been provided as a device for easily boiling a small amount of water, about the size of a cup. As shown in Fig. 6, this water heater has a main body A with a rod-shaped heater B facing downward.
Further, this main body A has a mounting groove C formed therein. When the main body A is attached to the pot D by fitting the mounting groove C into the edge E of the pot D filled with water, the heater B is immersed in the water inside the pot D.
Thereafter, by energizing the heater B, the water in the pot D is heated and becomes hot water.

[Problem that the invention attempts to solve]

By the way, in the water heater having the above configuration, the main body A' cannot be attached to a ceramic teacup or the like whose wall is thicker than the opening width F of the attachment groove C. In other words, the water heater described above is limited in the types of containers that can be used, resulting in poor versatility.

[Means and actions for solving problems]

In view of the above-mentioned circumstances, the purpose of this invention is to provide a highly versatile plunge-type water heater.
To achieve this purpose, the upper part of the stand is provided with an arm extending horizontally, a bar-shaped heater is installed in this arm extending downward, and the lower end of the stand is provided with a cut-out on the opposite inner side. A pair of legs having recessed portions are supported so as to be movable toward and away from each other along a substantially horizontal plane.

According to this configuration, the pair of legs are opened,
By juxtaposing the stand with the container, the rod-shaped heater can be immersed in the water poured into the container.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the drawings showing one embodiment.

1 to 3 show a water heater according to the present invention. This water heater 1 is
It is equipped with a stand 2 extending vertically in the figure,
An arm 3 is provided from the top of the stand 2 and extends in a substantially horizontal direction. Furthermore, a rod-shaped ceramic heater 4 is fixedly attached to the arm 3 so as to hang downward from its lower surface 3a (see FIG. 3). Furthermore, a pair of legs 5 and 6 are provided at the lower end 2a of the stand 2, facing in the direction in which the arm 3 extends, and extend so that the distance between them increases as they go toward the tip. The legs 5, 6 and the bottom of the stand 2 work together to hold the stand 2 upright. Further, in the figure, reference numeral 7 is a switch, reference numeral 8 is a pilot lamp, and reference numeral 9 is a power cord.

To boil water using the water heater 1 with the above configuration, first, as shown in Figure 1, pour water into the pot 1.
0 is placed between legs 5 and 6, and the ceramic heater 4 is immersed in water in the pot 10. Next, by turning on the switch 7, the ceramic heater 4 is energized, and the water in the cup 10 is heated by the heating of the ceramic heater 4 and becomes hot water.

On the other hand, the base ends 5a, 6a of the legs 5, 6 are
are pivotally supported by the stand 2, so that the legs 5 and 6 can be used in a position where they are far apart from each other as shown in FIG. It can be swung between a non-use position and a non-use position. Furthermore, the above foot 5,
6 are each provided with a stopper (not shown) so as not to swing inward from the non-use position shown. In addition, recesses 5d and 6d that are open upward are formed in the opposing inner surfaces 5c and 6c of the legs 5 and 6, respectively (see FIGS. 2 and 3). When 5 and 6 are placed in the non-use position, the tip 4a of the ceramic heater 4 fits into the recesses 5d and 6d. When the feet 5 and 6 are placed in the non-use position, the feet 5 and 6 are
Since the water heater 1 extends substantially parallel to the arm 3, the overall appearance of the water heater 1 becomes flat, and it does not take up much space when being transported or stored. Further, the tip portion 4a of the ceramic heater 4 has concave portions 5d, 6d.
Since the ceramic heater 4 is stored and held, damage to the ceramic heater 4 can be prevented as much as possible even if external force is applied during transportation or storage. Note that the reference numeral 11 in FIG. 2 is a cylindrical cover that covers the ceramic heater 4 when not in use.

Also, the arm 3 of the water heater 1 is the stand 2.
It is configured to be detachable from the As shown in FIG. 3, a pair of engaging recesses 12a and 12b are formed on the upper end surface 2b of the stand 2, while a pair of tongue pieces 13a and 13b are protruded from the end bottom surface 3b of the arm 3. The arm 3 is held at the upper part of the stand 2 by fitting the tongues 13a and 13b into the engaging recesses 12a and 12b, respectively. Note that the power cord 9 is pulled out from the bottom surface 3b of the end of the arm 3, while the back of the stand 2 has a
A groove 14 is formed for letting the power cord 9 escape when the arm 3 is attached to the stand 2.

As mentioned above, the arm 3 can be attached to and detached from the stand 2, so the arm 3 can be attached to the stand 2 in various ways.
It can be used in combination with. Figure 4 shows an example of this, in which the handle of the cup functions as a stand. A handle 21 is fixed to the tip 20, and a pair of engagement recesses 22 are provided on the upper end surface 21a of the handle 21.
a, 22b are formed. Each engagement recess 2
2a, 22b, tongue pieces 13a, 13b of the arm 3;
By fitting the above-mentioned handles 21
Arm 3 is attached to. Furthermore, when the arm 3 is attached to the handle 21, the ceramic heater 4
is located inside the tip 20 (see Fig. 5).
In the above configuration, when it is desired to boil water, water is first poured into the pot 20 with the arm 3 removed, and then the arm 3 is attached to the handle 21. Next, when the switch 7 is turned on, the ceramic heater 4 is energized, thereby heating the water in the pot 20 and turning it into hot water. Thereafter, the arm 3 can be removed and used in the same way as a regular pot with a handle.

[Effect of idea]

As described in detail above, according to the water heater according to the present invention, an arm extending horizontally is provided at the upper part of the stand, a rod-shaped heater is installed downwardly on this arm, and further, a rod-shaped heater is provided at the lower end of the stand. , a pair of legs having notch recesses on opposing inner surfaces are supported so as to be movable toward and away from each other along a substantially horizontal plane.

According to the above configuration, in order to immerse the rod-shaped heater into the water poured into the container to boil water, it is only necessary to open the pair of legs and place the stand side by side with the container. Regardless of the method, it becomes possible to boil water using a wide variety of containers, providing extremely high versatility.

In addition, by closing the above pair of legs, the overall appearance becomes flat, so it does not take up much space during transportation or storage.Furthermore, by closing the pair of legs, the tip of the rod-shaped heater can be Since the heater is housed and held in the recess formed in the leg, damage to the heater can be prevented.
