Description

[Detailed description of the invention] The invention relates to a rice cooker equipped with a heater and an electric timer for controlling rice cooking.The purpose of the invention is to prevent the electric timer from being affected by heat generated by the heater. A method of cooking rice that can effectively protect the timer from the heat from the heater and the harmful effects of water caused by condensation of steam generated during rice cooking, and also simplify the installation work of the timer. It is to provide the equipment.

An embodiment of the present invention will be described below with reference to all the drawings.

1 is the main body of the rice cooker, which consists of a substantially cylindrical outer case 2. A bottom frame 3 fitted to the lower part of the outer case 2. An inner case 4 disposed inside the outer case 2, a heat insulating material 5 disposed between the outer case 2 and the inner case 4, and an indicator lamp 6 attached to the outside of the outer case 2 so as to extend vertically therein. It consists of a decorative cover 7 for storing electrical equipment such as .6.

Further, reference numeral 8 denotes a pot detachably disposed within the inner case 4;
1 is a heater disposed at the inner bottom of the inner case 4, and 10 is a lid provided with a handle 11.

Reference numeral 12 denotes a temperature switch of a well-known configuration, which includes a magnetic temperature sensing section 13 that is pressed into contact with the outer bottom of the pot 8. It consists of an operating lever 14 whose one end is connected to the temperature sensing part 13 and whose other end projects outward from the decorative cover 7, and a microswitch 15 which is operated in accordance with the reciprocating rotation of the operating lever 14.

Incidentally, 16 is a well-known cord reel portion disposed on the outer bottom of the bottom frame 3.

Therefore, the decorative cover 7 has a shape in which the lower part thereof is bent so as to be substantially parallel to the bottom frame 3, and the bent end portion is located above the bottom frame 3 and is approximately parallel to the bottom frame 3. Parallel heating plates 17 are connected and held by integral molding.

On the other hand, a concave portion 18 is formed in a portion of the bottom frame 3 that faces the bottom heating plate 17 from below, so that the bottom heating plate 17 is positioned so as to cover the concave portion 18 from above. has been done.

A timer 19 for controlling rice cooking, which is located in the recessed part 18, is arranged and fixed on the lower surface of the heat plate 17.

The timer 19 has an electrical configuration that uses a timer motor to operate a cam switch in a predetermined manner. Specifically, the timer 19 operates for a predetermined time after rice cooking is completed when the heater 9 is turned off by the temperature switch 12. It consists of a repeating timer that starts the timer operation, closes the cam switch for a certain period of time during the timer operation, reenergizes the heater 9, and executes so-called double cooking (for example,
(See 4th Patent Application No. 38971).

An annular ice-blocking wall 20 is integrally provided on the lower surface of the heat plate 17 so as to surround the timer 19 and project downwardly, while a plurality of drain holes 21 are bored in the lower part of the recessed part 18. It is set up.

According to the above embodiment, since the electric timer 19 is attached and fixed to the bottom surface of the heat plate 17, the heat effect of the heat generated by the heater 9 applied during rice cooking, etc. is reduced on the timer 19.
All of this can be effectively prevented by using the hot plate 17.
Thereby, the timer 19 can be effectively protected from the adverse effects of heat.

Further, according to the above embodiment, since the heat plate 17 is connected and held to the decorative cover 7, the timer 19 is set in advance to the heat plate 17 before the decorative cover 7 is attached to the outer case 2. All you have to do is attach it, and therefore, the wiring work related to the timer 19 can be easily done, and as a result, the timer 19 installation work can be simplified.

Furthermore, according to the above embodiment, the timer 19 is provided on the lower surface of the heat plate 17 and the annular ice-blocking wall portion 20 surrounds it.
Since the drain hole 21 is formed in the lower part of the concave part 18, water generated by condensation of steam inside the rice cooker main body 1 flows into the concave part 18 during rice cooking. However, this water can be prevented from coming into contact with the timer 19 by the ice wall part 20, and the iron water can be discharged from the drain hole 21 to the outside of the rice cooker main body 1, thereby protecting the timer 19 from the adverse effects of water. can.

Moreover, the effect that the timer motor of the timer 19 is cooled by the wind flowing through the water drain hole 21 can be expected.

As can be understood from the above, the present invention includes a heater and an electric timer for controlling rice cooking, which are respectively arranged inside the rice cooker main body, and electrical components, etc., located outside the rice cooker main body. 3. A rice cooker equipped with a decorative cover, a heating plate is connected and held to the decorative cover, and the timer is attached to the heating plate, thereby suppressing heat from the heater to the timer. The invention is characterized in that an ice wall surrounding the timer is provided on the heat insulating plate to hang down, thereby preventing the timer from generating heat from the heater and condensing water vapor generated during cooking. The timer can be effectively protected from the harmful effects of heat, and the timer installation work can be simplified. It is something.
