JPH09192014A - Opening and closing device of charging cover of washed rice cooker - Google Patents

Abstract

PROBLEM TO BE SOLVED: To securely protect troubles of the detector for the charging cover, by providing an opening/closing device of the charging cover at the body frame of the rear outside of a rice cooker and also providing a detector for the presence of the charging cover at the rear outside of the opening/closing device. SOLUTION: An opening/closing device 42 for a charging cover 41 opening or closing the mounting aperture of a rice cooker 4 cover 9 is provided at the body frame 5 of the rear outside of the rice cooker 4 and a detector 43 for the presence of the charging cover 41 is provided at the rear outside of the opening/closing device 42. That is, the detector 43 of the charging cover is arranged at the further rear outside of the opening/closing device 42 arranged at the body frame 5 of the rear outside of the rice cooker. In this arrangement, troubles of the detector 43 of the charging cover, caused by the cooking heat or steam, are eliminated. Hence, the presence of the charging cover 41 can be always accurately detected. When rice has been completely cooked, the rice cooker 4 is pulled out to the front outside from the body frame 5 and then cooked rice is taken out. And hence, still more, influence of the heat or steam is less.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading lid opening / closing device for a rice washing and cooking machine.

[0002]

2. Description of the Related Art In a conventional rice-cooking rice cooker, the presence or absence of a charging lid provided above the supply port provided on the lid of the rice cooker is detected by the charging lid detecting means provided at the top of the rice cooker, When it is detected that the lid is present, the opening lid is controlled to move to the open state by the opening and closing device, the supply port is opened, and both the washed rice and the water are supplied from the opened supply port. When the supply of these is completed, the opening lid is controlled to move to the closed state by the opening / closing operation device, and when the supply port is closed by the opening lid, rice cooking is started by the rice cooker to cook rice. To be done.

[0003]

When the rice is cooked, the charging lid detection means is installed on the top of the rice cooker, which causes heat generated during the rice cooker or steam generated during the rice cooker. In some cases, the closing lid detecting means may fail and the presence / absence of the closing lid may not be accurately detected. This is intended to be solved.

[0004]

To this end, according to the present invention, a rice cooker 4 for cooking white rice or the like is provided in a machine frame 5 so as to be movable back and forth, and a pot lid 9 of the rice cooker 4 has been washed with rice. A supply port 40 for supplying white rice is provided, an opening lid 41 is provided on the upper side of the supply port 40 so as to be openable and closable, and an opening / closing operation device 42 is provided on the rear outside of the rice cooker 4 for opening and closing the insertion lid 41. In addition to being provided on the frame 5, a closing lid detecting means 43 for detecting the presence or absence of the closing lid 41 is provided on the outer rear side of the opening / closing operation device 42.

[0005]

In the rice washing rice cooker, the presence or absence of the closing lid 41 provided above the supply port 40 provided in the pot lid 9 of the rice cooker 4 is determined by the outside of the opening / closing operation device 42 for opening and closing the closing lid 41. The input lid 41 is detected by the installed input lid detection means 43.
When it is detected that the rice cooker 4 is present,
The opening / closing operation device 42 provided in the rear outer machine frame 5 controls the movement to an open state, the supply port 40 opens, and both the washed rice and the water are supplied from the opened supply port 40. When the supply of these ends, the input lid 41
The opening / closing operation device 42 controls the movement to the closed state, and when the supply port 40 is closed by the input lid 41, rice cooking is started by the rice cooker 4 and rice is cooked.

[0006]

EFFECT OF THE INVENTION When the rice is cooked, the input lid detecting means 43 is used.
Is an opening / closing device 4 provided on a machine frame 5 outside the rice cooker 4
By being installed further rearward of 2 and above, the insertion lid detecting means 43 will not break down due to heat at the time of cooking rice, steam generated during cooking rice, etc. The presence or absence of the insertion lid 41 can always be detected accurately. When the rice cooker 4 finishes cooking, the rice cooker 4 is pulled out from the inside of the machine frame 5 to the front outside,
By removing the rice, it is less affected by heat and steam.
