て健康を損なう恐れがある等の問題点があった。Although it is possible to prevent the main body 1 from moving by pressing the hook lever button part 15 while holding the hinge side with the other hand, it is necessary to hold the hinge side with one hand each time, making handling operations extremely cumbersome. In addition, the force of pressing the button horizontally is combined with the opening operation of the lid 7 that causes the center of gravity to shift, causing the main body 1 to suddenly move and knock over a bottle or container placed on the hinge 8 side, or the recoil of the push may cause the pot to move. The water inside 3 may vibrate and spill out. In particular, when a large amount of rice is cooked, the amount of water that flows out increases, and not only does the reduced amount of water have to be added, but it is also troublesome to clean up the rice and water that flow out. If the amount of water spilled is not replenished, there are problems such as the possibility of cooking raw rice with a core, which may be harmful to health.

It has a hinge mechanism that has a hinge spring that applies spring force, and a latch mechanism that has a push button that is provided on the other end side of the main body and is exposed on the side of the main body. In a rice cooker that automatically opens the top of the main unit by rotating around a hinge shaft, there is a hanger in which the upper end of the rice cooker is movably attached to the main body, and the locking part of the hanger faces toward the front side. A latch mechanism is comprised of a spring that applies spring force and a push button that is swingably suspended from the main body and has an upwardly inclined surface at the lower front surface, and that releases the engagement of the latch by pushing the inclined surface of the push button. This is a rice cooker that has been realized.

At this time, when the push button is pressed, the pushing force is divided into horizontal and vertical components by the upward pressing surface, and the push button rotates about the upper fulcrum. Since the pressing force applied to the push button is divided into two component forces, the force pushing the rice cooker body in the horizontal direction is weakened accordingly, and the movement of the rice cooker body is regulated. When the push button is rotated, the hanger is removed from the receiving part, and the lid body is automatically rotated by the spring around the hinge, and the upper part of the main body is opened. You can set the inner pot containing polished rice and water inside the open body, and press the button again to open the lid and check the water level. In addition, the rice that has just been cooked in the inner pot,
It is served in a rice bowl with shamoji.

The temperature of the water 41 inside rises and the steam generated flows into the steam cylinder 3.
8 is released into the atmosphere. When the rice cooking progresses and the water 41 boils and the moisture in the pot 11 decreases and the temperature rises rapidly, the control unit 19 that receives the detection signal from the temperature sensor 16 automatically stops the electricity supply to the heating coil 8 to prevent unevenness. Let's move on to the process. After the cooking process is completed, the device shifts to the warming mode, and at the scheduled time, the rice is evenly cooked until it is ready to eat, and a display and a blowing sound are emitted to indicate that the rice has finished cooking. The rice cooking, steaming, and warming processes are displayed in different colors by display lamps 34 on the inclined surface of the main body 1, and the rice cooking operation can be monitored from a distant location such as a dining table. When the latch mechanism 14 provided on the side of the main body 1 is operated, the lid body 24 rotates around the hinge shaft 26 due to the elastic force of the hinge spring, and the top surface of the main body 1 is automatically opened, allowing freshly cooked rice to be served. is served.

A push button 14j is provided to indirectly drive the push button 14j, and as described above, the push button 14j is formed with an upward pressing surface 14m. For this reason, when the pressing surface 14m is pressed after receiving the notification of the end of rice cooking through a blowing sound, the pressing force F is divided into horizontal and vertical component forces fh and fv, and the swinging end of the push button 14j is held in the pin position. Move counterclockwise around 14k (Figure 2
). When the push button 14j is moved, the hanger 14f rotates clockwise around the pin 14h while pushing the spring 14i, and as shown in FIG.
As shown in , the engagement between the locking portion 14g of the hanger 14f and the receiving portion 24a on the lid body 24 side is disengaged. Since the pressing force F applied to the push button 14j at this time is divided into two component forces fh and fv by the upward pressing surface 14m, the force pushing the rice cooker main body 1 in the horizontal direction is weakened accordingly, and the movement of the main body 1 is reduced accordingly. will be prevented.
