Description

[Detailed explanation of the idea] The present invention relates to an electric pot.

In general, electric pots require a plug receptacle with a connection terminal for the power source, and an indicator lamp to indicate the usage status, such as when the water is boiling, keeping warm, or a timer is running. The lamp case of the lamp is, for example,
As seen in the plug receiver disclosed in Japanese Patent No. 10551, it is usually formed separately from the bottom member of the outer case.

However, in such a conventional example, the number of constituent members and parts to be attached to each member increases, and the number of assembly steps also increases, leading to an increase in costs.

In order to solve the problems of the above conventional example, the present invention
In an electric pot that has a plug holder that connects to a power plug and a lamp case for an indicator lamp,
The plug receptacle and the lamp case are integrally formed with a bottom case attached to the lower end of the outer case, and at least the plug receptacle is integrally molded with the plug receptacle projecting upward.

According to this invention, the plug receptacle and the indicator lamp case are integrally molded with the bottom case attached to the lower end of the outer case, and the plug receptacle is in an upward protruding state, so that the number of parts can be minimized and the cost increase can be kept low. Moreover, since the plug receptacle and the like are provided in an upward protruding state on the bottom case, the protruding part serves both to position the bottom case and to prevent it from rotating, ensuring a secure attachment to the outer case.

The present invention will be explained in detail below based on embodiments shown in the drawings.

The first embodiment of the present invention shown in FIGS. 1 to 3 relates to an electric pot equipped with an air pump, which includes an outer case 1, a bottom case 2, a lower opening member (not shown), and a discharge pot. A stainless steel inner container is housed in a container body 4 made of a pipe case or the like, and a lid 6 equipped with an air pump (not shown) is pivotally attached to the container body 4. A band-shaped heater unit 9 including a water heater 7 and a heat-retaining heater 8 (see FIG. 3) is attached in a wound manner to the lower part of the side peripheral wall of the inner container 5. Above the heater unit 9, a thermostat 10 is attached to the side peripheral wall of the inner container 5. The bottom case 2 is made of synthetic resin and is formed into a ring shape, and a metal plate bottom plate 11 is attached in the space thereof. A metal inner container support member 13 is attached to the upper surface of the bottom plate 11 using screws 12. Further, a terminal 14 and a temperature fuse 15 are attached to this inner container support member 13. As shown in FIG. 1, a lamp housing case 18 is integrally formed on the front surface of the bottom case 2 (left end in FIG. 1), and includes a water boiling indicator lamp 16 and a heat retention indicator lamp 17 (see FIG. 3).

On the top of the rear part of the bottom case 2 (right side in Figure 1),
A plug receiver 19 made of synthetic resin is integrally molded. The plug receiver 19 is supported by the notch 20 of the outer case 1 at its upper side, lower side, and both sides, and force-fitting means is used as a fixing means therefor. ,
For example, screw fixing can be used. A connecting plate 22 having plug receiving connecting protrusions 21, 21 and a magnet 25 is attached to the lower part of the plug receiving member 19, and a timer 23 is attached to the upper part using screws 24, 24. In this embodiment, a mechanical timer is used as the timer 23, and the timer body 26 includes a timer mechanism T and a switch 27 (see FIG. 3).
The timer body 26 is arranged inside the plug receiver 19, and a dial 28 for setting the timer body 26 projects outside the plug receiver 19.
A power plug 29 is inserted into the connecting protrusions 21, 21.

The water boiling heater 7, the warming heater 8, and the thermostat 10 are wired as shown in FIG. The main circuit 30 is de-energized, while the switch 27 is closed after the set time of the timer 23 has elapsed (the same applies when the timer 23 is not activated), and the main circuit 30 is energized. . Incidentally, when the main circuit 30 is in the energized state,
When the temperature detected by the thermostat 10 is below a predetermined temperature, the thermostat 10 becomes energized and
The water boiling heater 7 mainly generates heat to bring the water to a boiling state, and the water boiling indicator lamp 16 lights up.
On the other hand, when the detected temperature exceeds a predetermined temperature, the thermostat 10 opens, the heat-retaining heater 8 mainly generates heat, and the temperature-retaining state is established, and the heat-retaining indicator lamp 17 lights up. In addition, in FIG. 3, r and r are resistances.

Further, in FIG. 1, 31 is a liquid pumping pipe, 32 is a discharge pipe, and 33 is a handle. Further, 34 is a heat insulating material that covers the inner container 5, and the lower rear end of this heat insulating material 34 is used to insulate between the timer main body 26 and the heater unit 9, so that the heat from the heater unit 9 is transferred to the timer. It is made so that it is difficult to be transmitted to the main body 26.

In the second embodiment of the present invention shown in FIG. 4, when the timer 23 is not operating, the changeover switch 38 is closed to the main circuit 30 side, and the main circuit 30 is in an energized state. At this time, timer lamp 3
5 and 36 are off. Next, when the timer 23 is set to a predetermined set time, the changeover switch 38
is closed to the electric motor M side, and the electric motor M is energized and operates, while the main circuit 30 is de-energized. At the same time, the timer lamps 35, 3
6 lights up. Since the timer lamps 35 and 36 are attached not only to the back but also to the front of the container main body 4, whether or not the timer 23 is set can be easily checked from the front.
When the set time of the timer 23 has elapsed, the changeover switch 38 is switched to the main circuit 30 side, the main circuit 30 is energized, and water boiling is started. At the same time, the timer lamps 35 and 36 are turned off.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, the present invention can be implemented in a general electric pot that is not equipped with an air pump. Further, the main circuit 30 is not limited to that shown in the above embodiment, and any form may be used as long as it includes the water heater 7 and the heat-retaining heater 8. Further, in the above embodiment, the plug receptacle 19 is provided with a magnet 25, but the plug receptacle 19 may be configured to allow a normal power plug 29 to be inserted therein.

Since the present invention has the above-mentioned configuration, it is possible to minimize the increase in the number of components and parts to be attached to each component in an electric pot having a plug holder and a lamp case, thereby reducing assembly man-hours and costs. In addition, the bottom case can be positioned or prevented from rotating with respect to the outer case by fitting the plug receiver etc. integrally provided with the bottom case with the outer case, and the two can be easily and reliably connected. In this case, it is possible to provide an electric pot that does not cause rattling even when the plug receiver and the like are integrated with the bottom case and also used for the rotation prevention and positioning purposes.
