2. Description of the Related Art Conventionally, in various types of cookers typified by rice cookers and electric pots, a lid at an upper part of a main body is made detachable from the main body so that the lid can be easily washed. In some cases, the cleanability of the lid is improved. On the other hand, by providing the operation panel with the operation unit and the display unit on the lid, the user can operate the operation unit without bending, and moreover, the display can be easily visually recognized.
Some of them have improved usability as cookers. Therefore,
It can be easily analogized that by combining these components, both cleanability and usability can be improved.

However, the structure in which the cover and the main body are detachable with the cover provided with the operation panel is in a situation where the structure is complicated and difficult to realize. Specifically, when an operation panel is provided on the lid, a control board for mounting an operation unit and a display unit is provided inside the operation panel,
A control board inside the operation panel and thus the lid,
A signal line for transmitting control signals is required between a power supply provided inside the main unit and a heating substrate (a substrate that controls heating means such as a heater and a heating coil). In order to separate the lid and the main body from the hinge part that supports the shaft, a structure that can be easily attached and detached while increasing the reliability of the wiring of the signal lines from the operation panel is required. For this reason,
If the lid can be removed from the main unit, the actual situation is that the operation panel is not provided on the lid, but an operation panel is provided at the top of the main unit to cope with the situation. Is disadvantageous in that the size in the front-rear direction increases.

[0004] When the lower surface of the lid facing the upper surface of the container is heated by the lid heating means for the purpose of preventing dew condensation or the like, similarly to the case where the operation panel is provided on the lid, a hinge portion is used. It is necessary to connect the power line of the lid heating means so as to be detachable. For this reason, when the lid can be removed from the main body, the lower surface of the lid is formed of a metal material, and the heating plate provided on the upper surface of the main body is brought into contact with the periphery of the lower surface of the lid, so that the heat from the upper part of the main body can be removed. The lower surface of the lid is heated by conduction, and the power line of the lid heating means is not wired to the hinge portion. However, in such a configuration, when a foreign object is caught in the contact portion between the heating plate at the upper part of the main body and the periphery of the lower surface of the lid or the contact condition is deteriorated due to deformation of the lower surface of the lid, the lower surface of the lid is heated. Has the disadvantage of causing unevenness.

In view of the above problems, the present invention has a structure in which the lid can be removed from the main body without impairing the reliability of the signal line wiring of the operation panel in a state where the operation panel is provided on the lid.

The base member 35 is formed integrally with the base member 35. The rear part of the base member 35 is supported by a hinge shaft 36 provided on the upper part of the main body 1. The base member 35 does not necessarily need to be supported by a shaft member such as the hinge shaft 36, and various hinge portions other than the shaft member may be used as long as the base member 35 can be rotatably provided with respect to the main body 1. The pivot support in the present invention means that the base member 35 is provided rotatably with respect to the main body 1.

An operation panel 38 is provided on an upper surface of the base member 35, that is, a concave window portion 37 formed near the upper front of the panel base 32. The operation panel 38 includes an operation unit 39 related to cooking operations such as rice cooking and heat retention, and a display unit 40 for displaying, in addition to the current time and the timer time, a process display and a cooking related menu such as a selected rice cooking menu.

Reference numeral 41 denotes a cover member that forms the lower surface of the lid 31 facing the upper surface of the main body 1 and a part of the upper surface of the lid 31 so as to surround the periphery of the base member 35. This cover member 41
The outer cover 42 forms a part of the upper surface of the lid 31 and forms a periphery of the base member 35, and the outer lid cover forms the lower surface of the lid 31.
43 and an inner lid 44. The part of the upper surface of the lid 31 formed by the outer lid 42 indicates the outer surface of the lid 31 around the base member 35, and the area exposed on the outer surface of the lid 31 may vary. Regardless, if the upper surface area (occupied area) of the lid 31 formed by the base member 35 is relatively small, the upper surface area of the lid 31 formed by the outer lid 42 is increased.

When the hinge shaft 36 is set to the rear, the cover member 41 is configured to be pulled out from the front side of the base member 35, detached, pushed in, and mounted. That is, the base member 35 has an outer shape in which the front side is formed in a U-shape when viewed from a plane, and the guide groove 46 is formed along the side surface. A U-shaped recess 47 having a shape matching the base member 35 is formed in the cover member 41, and a guide projection 48 with which the guide groove 46 can be engaged and disengaged is formed along the side surface of the U-shaped recess 47. It is formed. The structure for attaching and detaching the cover member 41 is not limited to the present embodiment, and may be appropriately changed in consideration of the detachability of the cover member 41. Also, when installing the cover member
Some locking mechanism may be provided to prevent 41 from easily detaching. In this case, the cover member 41 is detached from the base member 35 after releasing the lock mechanism, so that the cover member 41 does not accidentally come off and the safety is improved.

Inside the base member 35, a lid heating means 49 for heating the inner lid 44 corresponding to the lid lower surface member formed by the cover member 41 is provided. The configuration is such that the 44 is heated to reduce the condensation of water on the inner lid 44. The material of the inner lid 44 is made of austenitic stainless steel or an aluminum plate made of anodized metal, and is made of a material having good heat conductivity in order to prevent corrosion due to steam and reduce uneven heating of the cooking object in the pan 5. Is selected. The material of the heat radiating plate 34 that forms the lower surface of the base member 35 facing the inner lid 44 is made of austenitic stainless steel or a metal obtained by anodizing an aluminum plate, and is formed by a cord-shaped electric heater provided on the back surface of the heat radiating plate 34. When the lid heating means 49 heats the radiator plate 34, the radiator plate 34
Is efficiently radiated to the inner lid 44, and even when the lid heating means 49 is abnormally heated, the radiator plate 34 is prevented from melting. In addition, the material of the inner lid 44 is a magnetic metal such as a ferritic stainless steel or an enameled plate,
The heat radiating plate 34 may be formed of an electrically insulating material such as polypropylene, a heating coil may be provided as the lid heating means 49 inside the lid 31, and the inner lid 44 may be heated by electromagnetic induction. In this case, since the inner lid 44 itself generates heat, the temperature of the radiator plate 34 does not rise so much, and the radiator plate 34 can be formed of a plastic material. Therefore, there is an advantage that the lid 31 can be easily formed in a free shape corresponding to a complicated structure.

Inside the base member 35, there is provided a lid temperature sensor 51 as lid temperature detecting means for detecting the temperature of the inner lid 44. The lid temperature sensor 51 has a built-in thermistor or the like as a heat-sensitive element, detects the generation of steam from the inside of the pot 5 when cooking rice or keeping warm, and prevents condensation on the inner lid 44 when cooking rice or keeping warm. Therefore, it is used for purposes such as setting a heating temperature. The lid temperature sensor 51 is urged downward by a spring 52 serving as an elastic member on the upper surface of the inner lid 44, but the outer shell of the lid temperature sensor 51 that contacts the inner lid 44 selects a material similar to the inner lid 44. I do. This is to prevent electrical corrosion due to the difference in metal ionization tendency. Therefore, when the inner lid 44 is made of stainless steel, the outer heat-sensitive portion of the lid temperature sensor 51 is also made of stainless steel.

By the way, in a cooker provided with a lid temperature sensor for detecting the steam generated from the inside of the pan or the temperature of the lower surface of the lid inside the lid facing the pan, the heat-sensitive portion of the lid temperature sensor is used. When formed of stainless steel, this stainless steel has poor heat conductivity as compared with aluminum, and has a problem that heat conductivity to an internal thermistor is poor. Therefore, the lid temperature sensor cannot perform accurate temperature detection, and there is a concern that the performance of the cooker is adversely affected.

In order to solve such a problem, in the present embodiment, the thickness of the heat-sensitive part of the lid temperature sensor 51 which is in contact with the inner lid 44 which is the lower surface of the lid 31 is formed as thin as 0.1 to 0.3 mm. are doing. This focuses on the fact that stainless steel has higher strength than aluminum, and the thickness of the heat-sensitive part of the lid temperature sensor 51 can be made as thin as possible within an allowable range where the strength is not impaired. In addition, it is possible to eliminate poor thermal conductivity with respect to the internal thermistor. This configuration is not limited to the present embodiment, and the inner lid is brought into contact with the lid
Applicable to all cookers that detect 44 temperatures.

The lid packing 53 is made of an elastically deformable member, and is specifically made of silicone rubber or fluorine rubber. In addition, when the pot 5 is provided inside the main body 1 as in the present embodiment, and rice is cooked or kept warm in the pot 5, the lid packing 53 is brought into contact with the upper surface of the pan 5, and the lid 31 and the main body 1 are placed. What is necessary is just to prevent vapor from leaking out from the gap between the first and the second.

On the front front side of the main body 1 on the side opposite to the hinge shaft 36, a hook button 54 as a lid locking portion is provided. The hook button 54 is provided so as to be rotatable about a hook shaft 55, and is constantly urged by a hook spring 56 in a direction in which the hook button 54 projects forward. Also,
On the front part of the cover member 41, a hook part 58 is formed as a projection to be engaged with the claw part 57 of the hook button. When the lid 31 is to be closed with the hinge shaft 36 as the center of rotation, the claw 57 of the hook button 54 goes over and engages the hook 58 against the elasticity of the hook spring 56. As long as the hook 54 is not operated, the engagement between the claw portion 57 of the hook button 54 and the hook portion 58 is maintained by the elasticity of the hook spring 56, and the lid 31 is held in the closed state. Also, the lid 31
When the hook button 54 is operated from the front of the main body 1 in a state in which is closed, the hook portion 57 of the hook button 54 is disengaged from the hook portion 58, and a hinge spring (not shown) provided on the hinge shaft 36 is provided.
The lid 31 is automatically opened by the elasticity of the cover 31.

The inner lid 44 is provided with a steam hole 61 for discharging steam generated from the inside of the pot 5 during cooking such as rice cooking. Further, the base member 35 facing the steam hole 61 includes:

It is mounted on a plate 34. The steam port packing 64 is formed with an engagement projection 66 protruding inward. When the steam port 63 is pushed from above the concave portion 62, the flange 67 at the lower end of the steam port 63 is engaged with the engagement projection 66. 66, the steam port 63 is housed in the recess 62, and conversely, the base member
When the steam port 63 is pulled up from above the 35, the engagement between the flange portion 67 and the engagement projection 66 is released. Reference numeral 68 denotes a plurality of steam outlets formed on the upper surface of the steam port 63.

Here, the configuration around the lid temperature sensor 51 will be described with reference to FIG. 5. The lid temperature sensor 51 has a thermosensitive element 72 such as a thermistor for connecting a pair of signal lines 71. Are recesses 75 formed in the head 74 of the holder 73.
It is attached to. The lower surface of the heat-sensitive element 72 is covered with a plate-shaped heat conductive material 76 having good heat conductivity, and a cup-shaped head 74 of a holder 73 on which the heat-sensitive element 72 and the heat conductive material 76 are mounted. Of the heat sensitive plate 77 is fitted. Then, the heat-sensitive element 72 and the heat conductive material 76 are fixed in a tight contact state inside the concave portion 75, and the heat conductive material 76 and the heat-sensitive plate 77 are also in close contact with each other. Although the signal line 71 is led out from the hollow portion 79 of the holder 73, a filler 78 is injected into the hollow portion 79, thereby fixing the signal line 71 near the thermal element 72. .

On the other hand, the head 74 of the holder 73 has a flange 80
A spring 52 that presses the lid temperature sensor 51 against the inner lid 44 is provided between the flange 80 and the panel base cover 33. As a result, the heat-sensitive plate 77 is
And the lower end thereof is always in contact with the back surface of the inner lid 44. Since the heat-sensitive element 72 of the lid temperature sensor 51 is pressed and fixed to the holder 73 together with the heat conductive material 76 inside the heat-sensitive plate 77, even if the tension of the signal line 71 is applied, the heat-sensitive element 72 can be easily heated from the heat-sensitive plate 77. The element 72 does not float. Therefore, it is possible to prevent the temperature detection performance of the lid temperature sensor 51 from deteriorating. In addition, as described above, the inner cover that is always in contact with the material of the heat sensitive plate 77 is provided.
By using the same material as 44, even if moisture adheres during use, there is no fear of electrical corrosion due to the difference in metal ionization tendency. In addition, a heat sink
An elastically deformable sensor packing 83 for closing a gap with the sensor packing 34 is provided. Thereby, it is possible to prevent water from entering the inside of the lid 31 when cleaning the cooker.

Next, the detailed configuration of the operation panel 38 will be described with reference to FIG. In the concave window portion 37 of the base member 35 located on the back side of the operation panel 38, operation buttons 85 constituting the operation portion 39, a display 86 such as an LCD or LED constituting the display portion 40, and a control device An operation board 88 on which a microcomputer 87 is mounted is provided.

90 is provided in a state where a coating is formed on the surface of the sheet member 91. The panel member 89 is formed of a transparent AS resin or the like, and the sheet member 91 is also transparent.
It is formed of T resin or the like. Thus, an effect of decomposing oil stains adhering to the surface of the operation panel 38 during use is obtained. In addition, the surface of the operation panel 38, which cannot be removed from the lid 31 and is inferior in cleaning performance, can be made hard to adhere to the surface by the photocatalytic action of the photocatalytic film 90. Furthermore, even when the surface of the operation panel 38 is soiled, the hydrophilicity is enhanced by the photocatalyst film 90, so that the soil can be easily removed with a cloth soaked with water,
The cleaning property can be improved by compensating for the drawback that cannot be removed from the main body 1 and cannot be washed.

As described above, in the cooking device of the present embodiment, the base member 35 constituting a part of the lid 31 covering the upper surface of the main body 1 is pivotally supported on the upper portion of the main body 1 and the operating member is attached to the base member 35.

The operation panel 38 provided with any one of 40 is connected to the main body 1 via, for example, a hinge shaft 36 serving as a hinge portion when the base member 35 is supported by the main body 1. Therefore, the lid 31
In spite of the structure in which the operation panel 38 is provided on the side, the reliability of the wiring of the signal lines from the operation panel 38 is not impaired similarly to the conventional case where the operation panel 38 is provided on the main body 1 side. . Further, connection of signal lines from the operation panel 38 to the main body 1 becomes unnecessary, and the usability is improved by providing the operation panel 38 on the lid 31.

The base member 35 including the operation panel 38
The cover member 41 constituting the upper surface and the lower surface of the lid body 31 other than the
Since the cover member 41 is detachable from the base member 35, the cover member 41 alone can be removed from the lid body 31 to perform cleaning. In this case, since the electrical components of the operation panel 38 do not enter the cover member 41, even if water enters the inside of the cover member 41, no electrical problem occurs. Therefore, it is possible to immerse the lid 31 that is soiled at the time of use and to wash the lid 31 substantially in water, thereby significantly improving the cleaning property. Also, with the base member 35 of the lid 31 having the operation panel 38 pivotally supported by the main body 1, most of the outer shell of the other lid 31 can be attached and detached.
A structure in which the lid 31 can be substantially removed from the main body 1 can be realized, and the provision of the operation panel 38 on the lid 31 allows the main body 1 to be downsized. In other words, in a state where the operation panel 38 is provided on the lid 31, a structure in which the lid 31 can be substantially detached from the main body 1 can be easily realized without impairing the reliability of the connection of the signal lines of the operation panel 38, and the cleaning can be easily performed. It is possible to improve the operability and usability and to reduce the size of the main body.

The member 41 can be attached to and detached from the base member 35 from the front side of the base member 35. As a result, the cover member 41 is attached to the base member 35 with the lid 31 opened.
Simply pull it out from the front side of the
Can be removed from 31. Further, the cover member 41 is
When the cover member 41 is mounted on the cover member 31, the cover member 41 can be simply mounted on the lid 31 by simply pushing the cover member 41 from the front side of the base member 35. Therefore, the attachment / detachment of the cover member 41 is extremely good and can be easily performed, and the cover 31 with respect to the main body 1 is attached.
Can be easily attached and detached.

In this embodiment, in addition to the operation panel 38, an inner cover 44 serving as a lower surface member of a cover formed by a cover member 41 is provided.
Is provided inside the base member 35. As a result, the lid heating means 49 is provided inside the base member 35 pivotally supported on the upper part of the main body 1, so that the wiring of the lid heating means 49 can be performed similarly to the signal lines from the operation panel 38. For example, by using the space in the hinge portion connecting the cover and the lid 31, wiring similar to that of the related art can be performed, and the reliability of the wiring of the power line to the lid heating means 49 does not decrease. Therefore, a structure in which the lid 31 can be substantially detached from the main body 1 can be easily realized without impairing the reliability of the wiring of the power line to the lid heating means 49. Further, since the inner lid 44 formed by the cover member 41 is indirectly heated by radiant heat from the inside of the base member 35, a conventional structure in which the inner lid 44 is brought into contact with the heating surface of the upper portion of the main body 1 is used. In addition, it is possible to prevent the occurrence of uneven heating due to the deformation of the inner lid 44 and the pinching of foreign matter. Therefore, uneven heating of the object to be cooked is reduced, and the cooking performance can be improved.

In this embodiment having the lid heating means 49, in this embodiment, the material of the inner lid 44 formed of the cover member 41 is made of metal, and the base member 35 facing the inner lid 44 is made of metal.
The material of the radiator plate 34 as the lower surface member is made of metal, and a lid heating means 49 for heating the radiator plate 34 of the base member 35 is provided inside the base member 35. In this case, the metal has better heat conduction than plastic, and the heat of the heat generating portion of the lid heating means 49, which is local heat generation, is transmitted to the entire heat radiating plate 34 and dispersed, and the local heat to the heat radiating plate 34 is reduced. ease. In addition, the metal has good heat radiation due to the oxide film or the alumite film on the surface, and the heat radiation from the heat sink 34 is good, and the metal has good heat absorption due to the oxide film or the alumite film on the surface, The uniformly radiated heat is well absorbed by the inner lid 44. As a result, the inner lid 44 is uniformly heated with less temperature unevenness, and it is possible to provide a cooker with good heating efficiency and good cooking performance. Also, since the heat sink 34 is metal,
Even if the heating of the inner lid 44 becomes abnormal (continuous heating) in the event that the lid heating means 49 breaks down, the problem that the heat sink 34 is melted can be solved.

Further, either the heat radiating plate 34 or the inner lid 44,
Alternatively, if a plurality of uneven portions are formed on both surfaces of the heat radiating plate 34 and the inner lid 44, the surface area is increased, the heat radiation area or the heat receiving area is increased, and the heating efficiency is further improved. become.

In the structure provided with the lid heating means 49, the material of the inner lid 44 formed by the cover member 41 is made of magnetic metal, and the lid heating means 49 for electromagnetically heating the inner lid 44 inside the base member 35 is provided. May be provided. With this configuration, since the inner lid 44 itself generates heat, the heating efficiency of the inner lid 44 is increased, and when the object to be cooked needs to be heated, the inner lid 44 can be immediately heated. Further, since the lower surface member of the base member 35 facing the inner lid 44, that is, the heat radiating plate 34 can be made of plastic also for insulation of the heating coil, the heat radiating plate 34 and thus the lid 31
Can be made into a free shape, and the design is improved. Further, a lid heating means for the operation panel 38 provided on the upper surface of the base member 35

That is, it is possible to provide a cooker with excellent cooking performance that is excellent in instantaneous heat, and is also excellent in design, and furthermore, it is possible to reduce the thermal effect on the operation panel 38.

In addition, in this embodiment, the base member 35 is provided with a lid temperature sensor 51 as a lid temperature detecting means for detecting the temperature of the inner lid 44 formed by the cover member 41. In this case, since the lid temperature sensor 51 is provided on the base member 35 which is pivotally supported on the upper part of the main body 1, the wiring of the lid temperature sensor 51 is similar to the signal line from the operation panel 38.
For example, the same wiring as that of the related art can be performed by utilizing a space in the hinge portion connecting the cover 31 and the cover 31. Therefore, the lid 31
With the attachment / detachment, there is no need to removably connect the wiring of the lid temperature sensor 51 in the middle, and the temperature detection of the inner lid 44 can be accurately detected without impairing the reliability of the wiring of the lid temperature sensor 51. Can do it. In addition, since the temperature detection of the inner lid 44 becomes accurate, for example, when cooking such as rice cooking, it is possible to accurately detect boiling, adjust the amount of heating of the object to be cooked, and prevent spills and overheating. When keeping warm, heat the inner lid 44 properly
The heating of the inner lid 44 can be adjusted so as not to excessively heat the object to be cooked in the pan 5 from the inner lid 44 while suppressing the dew condensation of moisture on the 44.

In the present embodiment, a lid packing 53 for closing the gap with the main body 1 is provided around the lower surface of the lid 31 formed by the cover member 41. In this case, it is possible to prevent steam from leaking from the gap between the main body 1 and the lid 31 during cooking of rice cooking and the like, and to prevent intrusion of cool air from the gap during heat retention or the like, so that the pot 5 is kept at a uniform temperature. The temperature of the food inside can be maintained. The biggest advantage is that the lid packing 53
Is provided on the cover member 41, so that the lid packing
The cover member 41 can be removed from the base member 35 together with the cover member 53, and the lid packing 53 can be washed together with the components of the cover member 41 (in this embodiment, the inner lid 44 and the outer lid 42, etc.). As a result, the lid packing 53 and the lid
Although it was necessary to clean the gasket 31 and the gasket 31 separately, in this embodiment, the trouble is eliminated, and the cleanability of the lid packing 53 is significantly improved.

Further, since the steam port packing 64 is provided around the steam hole 61, the steam passing through the steam hole 61 is prevented from entering between the inner lid 44 and the heat radiating plate 34, and Dirt on the surface side of the plate 34 is prevented. Thereby, it is substantially only the cover member 41 that gets dirty during cooking such as rice cooking, and if the cover member 41 is removed and cleaned in a round during cleaning,
Even if the cleaning of the base member 35 is not performed, almost all the cleaning of the soiled portion is completed, and the labor for cleaning is reduced.

In this embodiment, a hook 58 for engaging the cover 31 with the main body 1 when the cover 31 is closed is provided on a part of the cover member 41. In this case, with the cover member 41 removed, the lid 31 cannot be closed to the main body 1 only by the base member 35, and with the cover member 41 removed,
It is possible to prevent cooking such as cooking rice or keeping warm by mistake. In addition, this effect can be realized with a very simple configuration in which the hook portion 58 is provided on a part of the cover member 41 without using a dedicated lid closing prevention mechanism.

In this embodiment, a steam port 63 for discharging steam from the inside of the main body 1 is provided at a position behind the operation panel 38. In this case, the steam outlet 63 is provided in front of the operation panel 38.
Is disposed, when operating the operation panel 38 during use, steam may hit the hand, or the display of the operation panel 38 may be difficult to see from the front of the main body 1 due to the generation of steam. Since the steam port 63 is located behind the operation panel 38, such a problem can be solved. Further, if the steam port 63 is behind the operation panel 38, the steam from the steam port 63 will not hit the hand when the lid 31 is opened and closed.

In the present embodiment, a steam port 63 for discharging steam generated from the inside of the main body 1 to the outside of the lid 31 is detachably provided on the base member 35, and the steam port 63 is provided from outside the base member 35.
