Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cooker, and more particularly to a rice cooker for reducing the size of a main body by rational arrangement of functional elements.

[0002]

In recent rice cookers, a handle for carrying the main body is movably provided on the side surface of the main body, and when moving the main body, the handle is raised and used for normal use. When the rice is cooked or kept warm, the handle is tilted to the rear of the main unit. Generally, the handle is U-shaped as a whole, and both ends of the handle are pivotally supported on both sides of the main body, and a horizontal handle for carrying is formed in the center, but the handle is tilted backward. In this state, if the handle has a large inclination to the rear, when the handle is raised when carrying the main body, there is a practical problem that the handle is difficult to raise because the handle has a lower position at the rear of the main body. Also, when the handle is tilted, only the handle is in a tilted position,
The appearance also deteriorates. Therefore, the structure is such that the handle receiving portion is projected on the rear surface of the main body so that the handle is in a substantially horizontal position when the handle is tilted.

On the other hand, the reduction of the space occupied by the installation and the reduction of the amount of materials used due to the downsizing of the main body has been a problem not only for rice cookers but also for various types of equipment. Normally, the body dimensions of the device are evaluated by the vertical (depth), horizontal (width), and height,
Actually, each dimension when the handle is tilted is what should evaluate the size of the main body. Therefore, the protrusion of the handle receiving portion toward the rear of the main body becomes an important factor for increasing the depth (front-back direction) of the main body. Further, the protrusion of the handle receiving portion has a problem that the outer box becomes large, for example, even when the main body is packed, the amount of packaging material used increases, and the space occupied by the warehouse increases. In addition, the structure in which the handle projects from the main body when the handle is tilted also causes a deterioration in the appearance of the rear portion of the main body.

In order to solve these problems, Japanese Patent No. 2720797 discloses an electric rice cooker in which a handle is pivotally mounted in the front-rear direction of the main body so that the handle can be rotated in an arc direction. It is disclosed that an upward step is formed, and when the handle is tilted rearward, the handle is placed substantially horizontally on the step. In this case, when the handle is tilted rearward, the difficulty of raising the handle due to the handle being in the lower position at the rear of the main body is eliminated, but when the handle is tilted rearward, both sides of the handle rest on the step. Since the outer surfaces of both side portions of the handle and the outer surface of both side portions of the main body are substantially flush with each other, it is difficult to put a hand on both side portions of the handle, and there is a concern that the handle is difficult to raise in another sense. In addition, the step portion as the mounting portion of the handle is also formed on the side of the shaft supporting portion of the handle,
The structure is such that the handle has to be attached to and detached from the main body while being placed along the step surface. Therefore,
In the normal use of holding the handle or placing the handle on the placing portion, there is a fear that the handle may come out of the main body due to force majeure.

By the way, in the case where the operation panel is arranged on the upper surface of the lid body, the main body can be downsized because the operation panel is not provided on the main body, and the usability is good in the upper surface operation.
Also, with movable handles arranged on both sides of the main body, you can hold the main body with one hand when carrying the main body, if you tilt the handle backward when cooking rice or keeping warm, you can hold the main body with one hand. This leads to improved usability. However, when the handle is tilted forward, it is necessary to avoid the problem that an impact is applied to the operation panel or the operation switch of the operation unit is erroneously pressed. That is, the impact when the handle is tilted forward may adversely affect the display unit and the operation unit that form the operation panel, or the operation switch may be erroneously operated. Also, even if you do not hit the operation panel, if the handle is tilted forward and the handle is located at the top of the operation panel, the display part will be hidden and you will not be able to operate it. As a result, the handle will get in the way, causing a problem in use.

[0006] Further, during cooking rice, steam is discharged from the steam port on the upper surface of the lid, and heating of the cooking rice is adversely affected. Therefore, carrying the main body should be prohibited. However, there are cases in which steam has not been completely discharged immediately after cooking rice, and in this case, carrying the main body with the handle may cause the steam to heat the hand.

Therefore, the present invention has a common object to eliminate various problems associated with the handle of the rice cooker, and provides a rice cooker capable of improving the handle mounting structure and downsizing the main body. That is the first purpose.

A second object of the present invention is to obtain a rice cooker capable of eliminating the deterioration of the appearance in the rear part of the main body .

A third object of the present invention is to prevent the operation panel from being impacted or causing a trouble in use when the handle is tilted forward, and moreover steam is generated when carrying the main body. To get a rice cooker that is hard to reach.

[0010]

Means for Solving the Problems] cooker according to the first aspect of the present invention, in order to achieve a pre-Symbol third object, the operation unit and a display unit on an upper surface of the outer lid to form the lid, or An operation panel provided with either an operation unit or a display unit is provided, a steam port for discharging steam to the outside is provided on the upper surface of the lid body, and a handle for carrying the main body is rotated on the upper side surface of the main body. The handle is rotatably supported so that when the handle is tilted forward, the handle does not come into contact with or overlap the operation unit or the display unit of the operation panel, and the handle is used to carry the main body. When the handle is made substantially vertical, the grip portion of the handle is prevented from being located immediately above the steam outlet of the steam port.

According to the structure of the first aspect , it is possible to eliminate the problem that the impact when the handle is tilted forward has a bad influence on the display section and the operation section of the operation panel and the operation switch is erroneously operated. In addition, when the handle is tilted forward, the display unit of the operation panel is hidden and cannot be seen, or the operation unit is hidden and cannot be operated. Furthermore, even if you hold the handle part of the handle to carry the main body when steam or steam is still generated from the steam port when keeping warm immediately after cooking rice, steam is not directly located at the steam outlet. It is hard to hit.

The packing 91 is provided in an annular shape. The lid packing 88 is made of an elastically deformable member, and is specifically made of silicone rubber or fluorine rubber. When the pan 5 is provided inside the main body 1 as in the present embodiment and the rice is cooked or kept warm in the pan 5, the lid packing 88 is brought into contact with the upper surface of the pan 5 to cover the lid 51 and the main body 1. It suffices to prevent steam from leaking through the gap between and.

Here, the structure of the handle 60 and its surroundings will be described in more detail. The handle 60 is substantially U-shaped as a whole, and the shaft portion 101 pivotally supported on both side surfaces of the main body 1 serves as a fulcrum.
A pair of arm portions 102, 102 which rotate along both side surfaces of the main body,
It is configured by a bar-shaped handle 103 that connects the arms 102 and 102. Then, the grip 103 is formed by the arm 102,
Despite the position of 102, the main body 1 and the lid 51
Are arranged horizontally across the left and right direction of the. On the other hand, in the upper rear part of the main body 1, a hinge portion 105 including the hinge shaft 55 that pivotally supports the lid body 51 and a hinge spring 104 that gives a force to open the lid body 51 is arranged. The rear portion 59 of the main body 1 is provided further rearward. As shown in FIG. 4, the rear portion 59 does not partially project from the rear surface (back surface) of the main body 1, but entirely projects rearward of the main body 1 over the entire width (left-right direction) of the main body 1. In other words, this portion is not the portion protruding from the main body 1 but the rear portion 59 itself of the main body 1. The rear outer surface 62, which is the rear outer surface of the rear portion 59, has a gentle curved surface shape without unevenness, and is connected to the outer surface that forms the outer bottom side (bottom plate 3) of the main body 1 and the outer surfaces on both sides of the main body 1. There is.

A mounting surface 61 is formed on the upper surface of the rear portion 59 corresponding to the stepped portion, on which the lower surface of the grip portion 103 of the handle 60 comes into contact when the handle 60 is tilted rearward of the main body 1. It The mounting surface 60 is formed only on the rear portion of the main body 1, and is not provided on both side portions of the main body 1. As a result, it becomes easy to put a hand on the side portion of the handle 60, that is, the arm portion 102, and the handle 60 can be easily raised even when the handle 60 is at the rear. Further, when the handle 60 is tilted to the rear of the main body 1, the rear outer surface 62 of the rear portion 59 of the main body 1, which corresponds to the receiving portion of the handle 60, that is, the outer surface of the outer frame 2 behind the space 27, becomes the handle 60. Is formed at substantially the same position as the outer surface on the rear side in the vertical direction so as to prevent unevenness. A vertical wall 107 that is substantially vertical is formed on the top of the mounting surface 61, and the vertical wall 107 and the mounting surface 61 form a recess 108 that receives the handle 60.

As described above, the handle 60 rotates about the shaft 101 within the range of a predetermined angle. In FIG. 1, in addition to when the handle 60 is tilted backward (position P1), when the handle portion 103 of the handle 60 is held by hand and the main body 1 is carried (position P3), the normal handle 60 is used. Although it is in use, in this embodiment, other than these positions, only at the position where the handle 60 is tilted to the frontmost position (position P2),
A handle attaching / detaching mechanism (not shown) capable of attaching / detaching the handle 60 to / from the main body 1 is provided. This prevents the handle 60 from coming off during normal use. Further, the operation panel 68 having the display unit and the operation unit is provided at a position deviated from the rotation range of the handle 60, and even when the handle 60 is tilted to the frontmost position, the operation unit and the display unit of the operation panel 68 are arranged. It is configured so that it does not come into contact with or overlap with the upper part. Further, when the handle 60 is made substantially vertical for carrying the main body 1, the grip portion 103 of the handle 60 is not covered by the lid 5.
The steam outlet 81 provided on the upper surface of 1 is not positioned directly above the steam outlet.

As shown in FIG. 5, the mounting surface 61 of the handle 60 provided on the rear portion 59 of the main body 1 behind the lid 51.
Is lower than the horizontal upper surface 100 of the main body 1 facing the lower surface of the lid 51. In addition, the depth width L of the above-described mounting surface 61
1 is formed to be equal to the thickness L2 in the height direction of the portion on the back surface side (back surface portion) of the lid body 51 or smaller than the thickness L2 of the back surface portion of the lid body 51 (L1 ≦ L2). In addition, the upper surface 100 of the main body 1
The height L3 from the mounting surface 61 to the mounting surface 61 is approximately the same as or slightly higher than the width L4 in the height direction of the handle 60 when the handle 60 is mounted on the mounting surface 61 (L3 ≧ L4). . That is, the height L3 from the upper surface 100 of the main body 1 to the mounting surface 61 is
The handle 60 is formed to have a height that is substantially the same as the width L4 of the handle 60 in the height direction.

The rear portion 59 of the main body 1 located below the mounting surface 61
In the space 27 formed inside, the electrical components such as the cord reel 24 and various boards (heating unit 21 and power supply board 2
5) is stored. Due to these electrical components, the mass of the rear part of the main body 1 located behind the center C of the main body 1 is larger than the mass of the front part of the main body 1 located forward of the center C of the main body 1. Therefore, when the main body 1 is lifted by holding the handle 60 with the rice in the pan 5, the shaft portion 101 of the handle 60 has a center C (to prevent the main body 1 from tilting forward or backward). It is located on the back side from the intermediate position between the back side and the front side of the main body 1. Handle 60 arm 102
The length of the handle 60 is shorter than that when the shaft portion 101 of the handle 60 is provided at an intermediate position between the front surface and the rear surface of the main body 1.
The impact force applied to the placement surface 61 is reduced when the is tilted backward. Further, it is possible to mitigate the adverse effects of vibrations exerted on the electrical components provided inside the rear portion 59 of the main body 1 and reduce the breakdown of the electrical components.

At the time of cooking rice, the pot 5 is heated by electromagnetic induction, and the amount of heating to the pot 5 is adjusted based on the temperatures detected by the pot temperature sensor 14 and the lid temperature sensor 70 and time management. Specifically, when rice is cooked, the rice to be cooked in the pan 5 and water are heated, and when the pan temperature sensor 14 for detecting the temperature of the pan 5 reaches a predetermined cooking temperature (for example, 120 ° C.), the rice is cooked. It stops heating and shifts to Murashi, which is continued for 15 minutes to cook the rice in the pan 5. In addition, heat retention heating is performed subsequent to heating rice. This heat insulation heating is done in the pan 5
Is heated by electromagnetic induction to adjust the heating amount to the pan 5 based on the temperature detected by the pan temperature sensor 14 and the lid temperature sensor 70 and the time management, and the temperature of the pan 5 detected by the pan temperature sensor 14 is adjusted. Is maintained at 60 ° C to 80 ° C. At this time, based on the temperature detected by the lid temperature sensor 70, the temperature of the inner surface of the lid 51 is kept slightly higher than the temperature of the rice in the pan 5.

Although not shown, a power supply voltage detecting means for detecting the power supply voltage supplied to the main body 1 at the time of rice cooking and heat retention is provided, and the power supply voltage is detected, and even if the power supply voltage fluctuates, the rating is obtained. The current value of the heating coil 11 is adjusted so that the heating output at a voltage (for example, AC 100 V) is kept. For example, if the heating output of the heating coil 11 is 500 W at the rated power supply voltage of 100 V and the power supply voltage fluctuates to 90 V or 110 V during heat retention, 500 W that is the heating output at the rated voltage can be kept. Even when the power supply voltage differs between homes or the voltage changes due to voltage drop during use, it is possible to maintain heat with a stable heating amount. Also, during rice cooking, a lid heater
The lid 51 is heated by 69, and the inner surface of the lid 51, that is, the inner lid
The dew condensation on 57 is reduced, and when the lid 51 is opened at the end of rice cooking, the phenomenon that dew drops from the lid 51 to the upper portion of the main body 1 is suppressed.

The handle 60 is configured to be placed on the upper surface of the rear portion 59 of the main body 1, and the handle 60 is detachably attached to the main body 1 when the handle 60 is tilted forward.

In this case, when the rice is cooked or the temperature is kept warm, the handle 60 is used in a state in which the handle 60 is tilted backward. The handle support portion, which is provided by partially protruding the outer shell of the main body 1 for supporting, is the outermost rear surface of the main body 1. A space is formed below the 60 and the handle support portion, and a wasteful space space is generated in the technique of reducing the size of the main body 1. However, in this embodiment, since the handle support portion when the handle 60 is tilted is provided on the upper surface of the rear portion 59 of the main body 1, no wasted space space is generated in reducing the size of the main body 1. The volume efficiency of the main body 1 is improved. In addition, when the rear side of the main body 1 is installed on the wall side during use, the handle
The space under 60 and the handle support is reduced as much as possible to reduce the installation space. Thus, the handle 60
The rear portion 59 of the main body 1 on which to mount the main body 1 is integrally formed with the outer shell of the main body 1 without locally protruding from the main body 1, thereby improving the mounting structure of the handle 60 and downsizing the main body 1. It is possible to improve the practicality, resource saving, designability, and handling of logistics. Further, since the rear portion of the main body 1 does not partially project, when the handle 60 is tilted rearward, a sense of unity can be obtained between the handle 60 and the outer shell of the main body 1. Therefore, the deterioration of the appearance at the rear part of the main body 1 can be eliminated.

Further, since the handle 60 is placed on the upper surface of the rear portion 59 of the main body 1 which is projected rearward from the hinge portion 105, when the handle 60 is tilted rearward, the handle 60 The side portion, that is, the arm portion 102 is in a state in which nothing is placed.
