Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric cooking device such as a domestic rice cooker.

Conventional Technology Traditionally, the main structure of this type of cooker was to open and close the outer lid with a handle, but in recent years, cookers with an automatic opening mechanism as shown in Figure 2 have become available. Ta.

That is, it has a pot 1 for storing food to be cooked, an outer lid 2 that covers the nigga opening, a biasing spring 4 provided on the hinge portion 3 of the outer lid 2, and a mechanism for locking with a hook portion 5. A control board 6 is provided near the hook part 6 in the outer cover 2 so that the top surface can be operated, and the outer cover 2 is automatically opened by operating the hook part 5. Ta.

Problems to be Solved by the Invention However, with such a structure, after the rice cooking is completed, the outer lid 2
When opening the lid, it opens automatically by operating the grip part 5, but since the center of gravity of the outer lid 2 is on the hook side, the inertial force of the outer lid 2 becomes strong.2-The opening angle exceeds 90°. At the same time, a strong inertial force was generated on the outside, causing problems such as a strong impact force, movement of the container body, and the possibility of damage to the hinge. Since there is a control board 6 to be operated, in order to avoid steam coming from the pot 1, an unintended switch may be turned on by mistake, and there is a risk of erroneous operation.

Therefore, the present invention provides a rice cooker that reduces the inertial force as much as possible when the outer lid is opened to reduce movement of the container body and malfunction of the container body, and reduces the risk of accidentally operating the switch on the operating section when the outer lid is closed. The purpose is to obtain.

Means for Solving the Problems and In order to achieve the above object, the present invention provides a hook portion in the direction opposite to the hinge portion of the outer cover, and an operating portion located approximately at the center of the hinge portion and the hook portion, or at the hinge portion. It is located close to the side.

Function: With the above configuration, the electric cooker of the present invention opens the outer cover after preparing or finishing cooking, so when the hook part is operated,
The outer cover opens automatically due to the biasing force of the spring, but since the center of gravity of the outer cover itself is located at the center or on the hinge side, the opening force can be set to be low, and if the opening angle exceeds 90°, the biasing force of the spring and the outer cover will open automatically. gravitational force acts in the same direction, but this reduces the moment applied to the hinge, reducing the risk of failure or damage to the hinge. In addition, when closing the outer lid, the operating part is set away from the hook side, which prevents steam from escaping from the pot, and allows you to operate it by placing your hand away from the edge of the outer lid. This reduces the risk of accidentally operating the switch part.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIG. 1, reference numeral 7 denotes a body with an open top, and a pot 12 for storing food to be cooked is detachably attached to a protective frame 11 disposed inside the body 10.

13 is an outer lid that covers the upper surface of the pot 12 and the body 10;
A spring 15 is disposed on the hinge portion 14 to bias the outer cover 13 in the opening direction. A hook portion 16 is formed on the side opposite to the hinge portion 14, and is configured to be able to be locked as appropriate. Reference numeral 17 denotes an operating section having a switch mechanism provided on the top side of the outer lid 13, and is located approximately at the center of the hinge section 14 and the hook section 16 or close to the hinge section 14 side.

A cable 18 is connected to the operating section 17, and is connected to a power supply board (not shown) inside the body 7 through the hinge section 14. This cable 18 is connected to the hinge portion 14
Since it can be bent at any time, materials with excellent bending durability are used. The shape of the outer lid 13 and the body 10 is cylindrical along the cylindrical steel 12, and only the hinge portion 14 side is protruded and is square, so that the space is minimized.

Reference numeral 19 indicates a hook button that operates to be engaged with the hook portion 16, and reference numeral 2o indicates a heat sink forming the lower surface of the outer lid 13.

Next, the operation of the configuration of this embodiment will be explained. When the hook button 19 is pressed to open the outer lid 13 in preparation for cooking, taking out food, etc., the hook portion 16 is released and the outer lid 13 is rotated by the biasing force of the spring 15 of the hinge portion 14. At this time, since the operation part 17 is located at the center of the outer cover 13 or on the hinge side, the center of gravity of the outer cover 13 approaches the hinge part 16 side, and the biasing force of the spring 15 can be set small, improving the durability of the spring 16 itself. . Furthermore, when the outer cover 13 opens and reaches an angle of 900 degrees or more, the rotational force of the spring 15 and the gravity of the outer cover 13 act in the same direction, increasing the overall rotational force of the outer cover, but the center of gravity of the outer cover 13 approaches the hinge side. Since the rotation moment is set as low as possible, it stops. Therefore, the impact force applied to the hinge portion 14 is reduced, and failures and damage to parts are reduced. Next, when closing the outer lid 13, operate the hook part 16 side of the outer lid 13 with your hand, but if food is stored in the pot 12, steam will flow out.
Push the outer lid 13 at a position away from the end surface. At this time, since the operating part 17 having a switch function is located away from the hook part 16 side of the outer cover 13, there is less risk of erroneous operation. Further, since the operating section 17 is close to the hinge section 14 side, the cable 18 connecting the operating section 17 and the internal wiring of the body 10 can be set short.

Effects of the Invention As described above, the present invention has an operation part having a switch function on the top surface of the outer cover, a spring that biases the hinge part of the outer cover in the opening direction, and a hook in the opposite direction of the hinge part of the outer cover. and the operating portion is provided at a substantially central portion between the hinge portion and the hook portion or at a position close to the hinge side.
When the outer cover is automatically opened, the center of gravity of the outer cover does not shift to the hook side, which reduces the set biasing force of the spring and improves durability.Even when the outer cover rotates beyond 90 degrees and stops, the inertia force is reduced. And the rotational moment is small, so there is little impact and durability.
Become highly reliable. Furthermore, when closing the outer lid, the operation part is not on the hook side, which reduces the risk of accidentally pressing the switch, making it safer. Furthermore, the cable passing through the hinge portion can be set short, reducing costs.
