(Example 1)

Example 1 of this invention is demonstrated using FIGS. The rice cooker main body 1 has a pot-shaped accommodating part 1a of a user cylinder shape, and the pot accommodating part upper edge part 1b is connected from the upper end part of the pot accommodating part 1a. The pot housing upper edge 1b supports the outer circumference by the outer circumferential wall surface portion 1c. And it is arrange | positioned that it is the metal main body cover 13 on the upper surface of the pot accommodating part upper edge part 1b.

The pot 2 is freely detachable from the top of the main body, so that the pot housing part 1a is detached, and the outer pot 2a of the pot 2 attaches the pot 2 to the pot housing part 1a of the main body 1. When stored, it is located above the pot accommodating upper edge 1b (FIG. 2).

The pot 2 is heated by an induction heating method by the heating coil 5 to cook and heat. Reference numeral 6 is a control unit for controlling the heating operation of the rice cooker. Reference numeral 15 denotes a floor sensor that detects the temperature of the pot 2 at the time of cooking and warming, and transmits a signal to the controller 6. Reference numeral 3 denotes a lid covering the upper part of the main body, and the hinge axis 4 is pivoted about the main axis to cover the main body 1 freely. The lid 3 has an inner lid 7 that is freely detachable and has a steam hole 7a through which steam during cooking passes. In addition, the lid 7 has a tubular steam port 9 through which steam during cooking flows out to the outside, and the steam port 9 and the inner lid 7 prevent steam from flowing into the lid 3. Encapsulate with steam packing 10. The inner lid 7 has an inner lid packing 8 in contact with the pot front portion 2a of the pot 2 on the outer circumference, and prevents steam during cooking from leaking outward from the steam port 9.

Steam generated from the rice during cooking or warming will come in contact with the inner lid (7). The steam contacting the inner lid 7 is cooled to form dew, and is attached to the inner lid 7. To reduce the adhesion of dew, the lid heater 14 heats the inner lid, but heating to the lid heater 14 is limited, because excessive heating causes the surface of the rice in the pan to dry or yellow. Dew will remain on the inner lid. In addition, the inner lid packing 8 is harder to heat than the inner lid 7, and dew is easy to attach.

When the lid 3 is opened, the dew attached to the inner lid 7 or the inner lid packing 8 falls downward, and eventually, on the pot housing upper edge 1b of the main body 1 or the pot of the pot 2. It is dripped on the whole 2a. The dew dropped on the pot front part 2a of the pot 2 is dripped on the pot storage part upper part 1b very soon, since the pot front part 2a is located in the upper surface of the pot accommodating part upper part 1b. (FIG. 3).

However, the pot housing upper edge 1b is covered with the main body cover 13, and the dew dropped from the inner lid 7 or the inner lid packing 8 accumulates on the main body cover. Since the main body cover is made of metal, water repellency is better than that of the upper portion of the pot housing portion 1b made of resin. For this reason, the dew dropped on the main body cover 13 can be easily wiped off with a cloth. In addition, although the rice pressure is also adhered to and attached to the pot housing upper edge 1b, since the main body cover is made of metal, it does not stick firmly and can be easily wiped off with a dishcloth, which is very hygienic and easy to clean.

And since the resin part is covered with metal, heat at the pot front part 2a of the pot is cut off by the main body cover, and the temperature of the pot accommodating part upper edge part 1b which is a resin part becomes lower than before. This resin part has high heat resistance, it is not necessary to use expensive resin with good dimensional stability, and inexpensive resin can be employ | adopted, and low cost is attained. In addition, since the temperature decreases, the amount of heat deformation of the resin portion is also reduced, and the step and gap between the lid and the main body are reduced, thereby improving the appearance quality and preventing discoloration due to aging deterioration of the upper portion of the pot housing portion.

The upper surface of the main body cover is provided with a U-shaped groove 13a in cross section (Fig. 4). Dew or rice grains are guided to the grooves and accumulated in the grooves, and do not fall to the outside of the body to pollute the outer wall or the bottom surface, or fall to the inner pot housing to pollute the inner wall surface. Moreover, the dew and rice grains left in the grooves are simply wiped off the grooves of the body cover, and the dew is easily wiped off and is very easy to clean. Although this groove | channel may be excreted over the whole periphery of a main body cover, only the vicinity of the hinge part in which dew is easy to drop | disappear is fully effective.

The bottom sensor 15 detects the temperature of the pot 2 and transmits a signal to the controller 6 as described above. However, if a foreign object such as water or a workpiece is attached, the bottom sensor 15 detects an incorrect temperature or cannot detect a temperature. As a result, the cooker does not operate normally. However, since the inner circumferential edge portion 13b is higher than the outer circumferential edge portion 13c (FIG. 4), the main body cover 13 has no water or blood overflowing from the main body cover even if water or a cooked object flows from the pot 2 by mistake. The food overflows outside the main body 1 and is not attached to the pot accommodating part 1a or the bottom sensor part 15. Furthermore, when the pot 2 is detached from the main body 1, the pot 2 is removed by holding the pot 2a of the pot, but the outer periphery of the main body cover 13 is the inner portion of the main body cover 13. Since it is lower than the peripheral part, it is easy to insert a finger in the lower part of the pot front part 2a, and the pan 2 is easily taken out.

The main body cover is made of metal, but since the main body 1 is made of resin, the dimensional shrinkage ratio due to aging deteriorates. For this reason, the main body cover floats or the cross section of the metal part is exposed. Here, it covers with the main body cover from the inner wall surface 1d of the pot accommodating part 1a to the outer peripheral wall surface part 1c of a main body, the inner wall surface 1d of the pot accommodating part 1a, and the outer peripheral wall surface part 1c of a main body. ) And a slight gap corresponding to the dimensional shrinkage in advance in the main body cover (FIG. 5), the gap between the main body cover 13 and the main body 1 becomes inconspicuous, and the cross section is not exposed. Moreover, the metal part is unevenly distributed in the outer part of the main body, and the texture of the main body appearance also increases due to the glossiness of the metal part.

Here, the metal body cover exhibits the effects of claims 1, 2 and 3 of the present invention regardless of the thickness. However, if the main body cover 13 is formed from a sheet metal part, the workability is good, and if too thick, the workability is poor. In addition, when the thickness of the main body cover 13 is thick, the material cost is high, and the rice cooker becomes more heavy than necessary, which causes inconvenience in transportation. In the present invention, about 1 mm or less (0.6-0.8 mm of material) The body cover is composed of thin plates.

The above embodiment is not limited to the method of the present embodiment for heating the pot, and the same effect can be obtained also with a heater system such as a casting heater.

Embodiment 2 of this invention is demonstrated using FIGS. 8-12. The rice cooker main body 101 has a user tub-shaped pot accommodating portion 101a, and the pot accommodating portion upper edge portion 101b is connected from the upper end of the pot accommodating portion 101a. The pot housing upper edge 101b is supported by the outer circumferential wall surface portion 101c. Then, the main cover 113 is disposed on the upper surface of the pot housing upper edge 101b.

The pot 102 is freely detachable from the top of the main body so that it can be freely attached to the pot housing 101a, and the outer pot 102a of the pot 102 allows the pot 102 to be attached to the pot housing 101a of the main body 101. When stored, it is located above the pot accommodating upper edge 101b (FIG. 9).

The pot 102 is heated by an induction heating method by the heating coil 105 to cook and heat. Reference numeral 106 is a control unit for controlling the heating operation of the rice cooker. Reference numeral 115 denotes a floor sensor that detects the temperature of the pan 102 at the time of cooking and warming, and transmits a signal to the control unit 106. Reference numeral 103 denotes a lid covering the upper portion of the main body, and the hinge shaft 104 is pivoted about the axis to cover the main body 101 freely opening and closing. The lid 103 is detachably free and has an inner lid 107 having a steam hole 107a through which steam during cooking passes. In addition, the lid 103 has a tubular steam port 109 through which steam in the outflow is discharged to the outside, and the steam port 109 and the inner lid 107 are provided such that steam does not flow into the lid 103. Sealed with a vapor port packing (110). The inner lid 107 has an inner lid packing 108 in contact with the pot front portion 102a of the pot 102 on the outer circumference thereof, and prevents the steam during cooking from leaking out of the steam port 109 to the outside.

Steam generated from the rice during cooking or warming will come in contact with the inner lid (107). The steam contacting the inner lid 107 is cooled to form dew, and is attached to the inner lid 107. The lid heater 114 heats the inner lid to reduce the attachment of dew, but heating to the lid heater 114 is limited because excessive heating causes the surface of the rice in the pan to dry or yellow. This will remain on the inner lid. In addition, the inner lid packing 108 is harder to heat than the inner lid 107, and dew is likely to adhere.

When the lid 102 is opened, the dew attached to the inner lid 107 or the inner lid packing 108 falls downward, and eventually, on the pot housing upper edge portion 101b of the main body 101 or the pot of the pot 102. It is dripped on the whole 102a. The dew dropped on the pot front part 102a of the pot 102 is dripped on the pot accommodating part 101b because the pot part 102a is located on the upper surface of the pot accommodating part 101b. (FIG. 10).

However, the pot housing upper edge 101b is covered with the main body cover 113, and the dew dropped from the inner lid 107 or the inner lid packing 108 is accumulated on the main body cover. In addition, a grain of rice may be attached to the main body cover 113 in some cases. Moreover, the rice cooker is often installed around the kitchen, and is exposed to the softness generated by cooking using oil, and the softness is attached to the upper portion of the pot accommodating portion 101b.

The circumference | surroundings of the pan storing part upper edge part 101b receive heat from the pot front part 102b of the pan 102, and it is temperature to the temperature which is easy to propagate at 60-70 degrees Celsius during cooking, and about 40-60 degrees Celsius during heat retention Rises. Dew, rice grains or softness attached to the periphery of the pot accommodating portion 101b are warm, and bacteria are easy to propagate, and mold or mold odors, decaying smells, and abnormal smells caused by various bacteria are generated. However, in the rice cooker of the present embodiment, since the main body cover is made of an antimicrobial material, propagation of various bacteria by dew, rice grains, or softening is prevented, and no mold, mold smell, decaying smell, or abnormal smell of various bacteria are generated. As an antibacterial material, when a main body cover is formed from a resin molded article, what is necessary is just to add an antibacterial agent to resin. Antibacterial agents include mainly silver-based inorganic antibacterial agents. In addition, when the main body cover is formed of metal parts, the main body cover 113 is coated with a ceramic material to which an antimicrobial agent such as silver-based inorganic antimicrobial agent is added to the metal surface, or a metal having an antimicrobial effect, for example, silver or copper. ) May be formed, or the surface may be formed by silver plating or copper plating.

While the dew and rice can be kept clean by removing the pot housing upper edge portion 101b, the softness cannot be wiped off simply by wiping with a dishcloth, and must be wiped off with a detergent or the like. However, since it was a part where food contacted, it had to be wiped off so that detergent might not remain, and it was laborious work. Here, in the rice cooker of the present embodiment, using the oil-decomposable material on the main body cover, the attached softening is decomposed into inorganic material. As an oil-decomposable material, there is a method of applying a titanium oxide-based ceramic material to the surface of the body cover 113 by using a photocatalytic action such as titanium oxide. By being decomposed into inorganic substances, no detergent or the like is required, and the cloth can be easily wiped off, and the care is very easy.

The rice attached to the pot housing upper edge 101b immediately dries and clings to the pot housing upper edge 101b. In addition, the flexibility is soaked so attached to the pot housing upper edge portion 101b is very difficult to wipe. However, in the rice cooker of this embodiment, a material having high water repellency such as fluorine is applied to the surface of the main body cover. Because of high water repellency, the grains of rice are hard to stick to, and the softness can be easily wiped off, so it is easy to clean.

The pot housing upper edge portion 101b is provided with a pot 102 and retains the outer portion of the main body 101 and the pot 102, so that sufficient strength is required. When the upper portion of the pot housing portion is made of metal, the weight of the rice cooker becomes heavy, making it difficult to carry the rice cooker, and also it is not able to withstand dropping impact, and in most cases, it is formed of a resin product. However, the resin is easy to be charged, and surrounding dust easily adheres to it. Since the upper portion of the pot housing 101b is easily in contact with food such as rice grains, the attached dust is not sanitary unless wiped off with a dishcloth. Here, in the rice cooker of this embodiment, since the main body cover 113 is comprised from the material which is hard to charge, it is hard to attach dust. The effort to clean the dust is greatly reduced, making it easy to clean. As a material which is hard to be charged, when a main body cover is formed from a metal or formed from resin, there exist methods, such as adding an antistatic agent to resin.

The effects described so far in the present embodiment have the same effect even if the heating method of the pot 102 is not an induction heating method but a rice cooker heated by a casting heater.

In the rice cooker for heating the pot 102 of the induction heating furnace of the present embodiment, magnetic lines are generated by induction heating. Magnetic lines may cause radio interference to electronic devices such as radios and televisions close to the main body, depending on the amount of generation. In some cases, a ring-shaped magnetic shielding plate is installed inside the main body to surround the pot 102, and the magnetic force lines are prevented from leaking out of the main body by the magnetic shielding plate, thereby preventing radio waves from interfering with an electronic device such as a radio or a television. Do not. Here, when the main body cover is formed of a material having substantially metal anti-magnetic effect, the main body cover acts as a magnetic shield plate. As a material having an anti-corrosion effect, a thin plate of stainless steel or aluminum is easy to process and can be made at a low cost, and furthermore, it is suitable as a material for a main body cover having a anti-corrosion effect because it is hard to corrode even when dew is dropped. In addition, when the main body cover is formed into a ring shape, the anti-corrosion effect is further improved.

Embodiment 3 of the present invention will be described with reference to FIGS. 13 to 19. The rice cooker main body 201 has the user tub-shaped pot accommodating part 201a, and the pot accommodating part upper part 201b is connected from the upper end part of the pot accommodating part 201a. The pot housing upper edge 201b supports the outer circumference by the outer circumferential wall surface portion 201c. Then, the main cover 213 is disposed on the upper surface of the pot housing upper edge 201b.

The pot 202 is housed in the pot storage unit 201a so as to be freely detachable from the upper side of the main body, and the outer pot portion 202a of the pot 202 attaches the pot 202 to the pot housing 201a of the body 201. When stored, it is located above the pot accommodating upper edge 201b (Fig. 14).

The pot 202 is heated by the heat generated by the bottom heater 205 to cook and heat. Reference numeral 206 denotes a control unit for controlling the heating operation of the rice cooker. Reference numeral 215 detects the temperature of the pot 202 at the time of cooking and warming with a floor sensor, and transmits a signal to the controller 206. Reference numeral 203 denotes a lid covering the upper portion of the main body. The hinge shaft 204 is pivoted about the main shaft to cover the main body 201 so as to be freely opened and closed. The lid 203 is detachably free and has an inner lid 207 having a steam hole 207a through which steam during cooking passes. In addition, the lid 203 has a tubular steam port 209 through which steam during cooking flows out to the outside, and the steam port 209 and the inner lid 207 prevent steam from flowing into the lid 203. Sealed with a vapor port packing (210). The inner lid 207 has an inner lid packing 208 in contact with the pot front portion 202a of the pot 202 on the outer circumference thereof, and prevents steam during cooking from leaking out of the steam port 209 to the outside.

Steam generated from the rice during cooking or warming will come in contact with the inner lid (207). The steam contacting the inner lid 207 is cooled to form dew, and is attached to the inner lid 207. The lid heater 214 heats the inner lid to reduce the attachment of dew, but heating to the lid heater 214 is limited because excessive heating causes the surface of the rice in the pan to dry or yellow. This will remain on the inner lid. In addition, the inner lid packing 208 is harder to heat than the inner lid 207, and dew is easy to attach.

When the lid 202 is opened, the dew attached to the inner lid 207 or the inner lid packing 208 falls downward, and eventually, on the pot housing upper edge 201 b of the main body 201 or the pot of the pot 202. It is dripped on the whole 202a. The dew dropped on the pot front part 202a of the pot 202 is dripped on the pot storage part upper part 201b soon after the pot front part 202a is located in the upper surface of the pot accommodating part upper part 201b. (FIG. 15).

In addition, the rice grains are attached to the upper portion of the pot housing portion 201b, or the rice cooker is often installed around the kitchen, and is exposed to the softness generated by cooking with oil, and thus the softness is attached.

The circumference | surroundings of the pan storing part upper part 201b receives heat from the pot front part 202a of the pan 202, and is temperature to the temperature which is easy to multiply germs at about 60-70 degreeC during cooking, and about 40-60 degreeC during warming Rises. Dew, rice grains, or softness attached to the periphery of the pot accommodating portion 201b are warm, and various germs are easy to breed, and mold or mold odors, decaying odors, and abnormal odors caused by various germs are generated.

However, in the rice cooker of this embodiment, the pot housing upper edge 201b is covered with the metal body cover 213. For this reason, the dew, rice grains, or casting | flow_spread which dripped from the inner lid 207 or the inner lid packing 208 accumulate on the main body cover 213. FIG. Since the main body cover 213 is made of metal, it is difficult to stick and can be easily wiped off with a cloth, so that the pot housing upper edge 201b can be kept clean.

Moreover, the metal body cover makes the glossiness which a metal has made a rice cooker feel cleanliness, and a high quality, and the marketability of a rice cooker becomes high.

Here, since the thin sheet of stainless steel and the thin sheet of aluminum are easy to process and hardly cause rust or the like, they are suitable as a material for the main body cover 213.

As shown in FIG. 16, when the main body cover 213 is installed with the screw 223, the main body cover 213 can be firmly attached to the upper portion of the pot housing portion. When the product is disposed of, the screw is removed, so that the main body cover 213 of the metal part and the main body 202 of the resin part can be separated in the vertical direction.

In addition, as shown in FIG. 17, the same effect can be acquired even if the pot accommodating upper-rim part 201b is a rice cooker which also serves as a main body outer peripheral part.

Further, the main body cover 213 has a hole-shaped mounting portion 220 that engages with the protruding engagement portion 219 provided in the pot housing portion and the outer circumferential wall surface portion. By removing the engagement with the engagement portion, it is disposed so as to be detachable freely in the vertical direction (Fig. 18). For this reason, the main body cover 213 can be disassembled and cleaned from a rice cooker and it is easy to clean it. When the entire pot housing upper edge 201b is covered with the body cover, only the main body cover 213 can be trimmed to remove dew, rice grains, or softening dropped onto the pot housing upper edge 201b.

The main body cover 213 has a ring shape, which covers the pot housing upper end 201b, the pot housing upper end 201d, and the main body wall surface upper end 201e, and which one of the main body 201 precedes. According to the main body 201, the portion along the main body 201 serves as a guide when the main body cover 213 is attached or detached in advance, so that the main body cover 213 can be detachably attached (FIG. 18). ). At this time, the portion along the main body cover 213 may be either a portion covering the outer circumferential wall surface portion 201c or a portion covering the pot housing portion 201a.

In FIG. 19, a slight gap 217 is provided between the main body cover 213 and the pot housing upper edge 201b. Since the main body cover 213 is made of metal, it has good thermal conductivity and becomes uniformly warmed at the time of cooking and warming. On the other hand, the pot accommodating upper edge 201b is often formed of a resinous component, and it is difficult to transfer heat. A slight gap 217 between the body cover 213 and the pot housing upper edge 201b serves as a heat insulating layer, and heat is hard to leak out of the body. Therefore, the quantity of heat which flows out outside at the time of cooking and warming is reduced, and power consumption is reduced. In addition, even if water enters between the main body cover and the upper part of the pot housing part, since the drain hole 218 is provided in the upper part of the pot housing part and the water is discharged to the outside, the abnormal odor or mold is released in the body. Does not occur.

In FIG. 20, reference numeral 216 denotes a bottom coil, which heats the pot 202 by induction heating instead of the floor heater 205 of the third embodiment. In the induction heating rice cooker, the resin pot accommodating portion 201a covers the pot to the pot bottom 202c. In the induction heating method, the pot bottom 202c is heated, and the temperature of the pot bottom 202c rises above the heat resistance temperature of the pot storage part, so that a slight gap between the pot storage part 201a and the pot bottom 202c is achieved. Install it. Compared with the pot bottom 202c, the pot front part 202a rises only to the temperature which can be sufficiently maintained if it is heat-resistant resin, and the pot 202 is pot top part 201b in the pot front part 202a. It is installed in).

The main body cover 213 is formed of a metal, and is easy to transfer heat. In direct contact with the pan 202, the body cover 213 takes heat from the pan 202 and the temperature of the pan 202 drops. Therefore, as shown in FIG. 21, when the pot mounting stand 221 formed of resin with heat resistance is arrange | positioned between the pot front part 202a of the pot 202, and the main body cover 213, the pot water may be used by the rice cooker of an induction heating system. The payment upper edge 201b can be made hygienic and easy to care for.

In addition, as shown in FIG. 22, when the pot accommodating part upper-end | tip part 201b is formed of resin with heat resistance, the pot mounting stand 221 becomes unnecessary and the pot 202 can be provided with a simple structure. And as shown in FIG. 23, it becomes a removal guide of the main body cover 213, and also attaches or detaches the main body cover 213 easily.

Here, although the main body cover 213 is detachably attached to the pot housing upper end 201b, when it is inserted into the pot mounting stand 221 and the pot housing upper end 201b, when the pot 202 is installed, The cover 213 can be securely mounted at a predetermined position, so that the cover 213 is not mounted in an accidentally injured state (Fig. 24).

As shown in FIG. 25, when the handle 222 is disposed on the pot 202 and the handle is formed of a heat resistant resin, the pot holder 221 becomes unnecessary and the pot 202 can be easily taken out of the main body. . In addition, since the temperature of the handle 222 of the pot 202 is only about 60 to 70 ° C. immediately after cooking, the pot 202 can be taken out of the body with bare hands without using pot tongs. Can be.

Embodiment 5 of the present invention will be described with reference to FIGS. 26 to 29.

26 is a cross-sectional view showing a rice cooker of a fifth embodiment of the present invention. The rice cooker main body 301 has the user cylindrical pot accommodating part 302, and the main body opening upper surface part 303 is connected from the upper end part of the pot accommodating part 302. As shown in FIG. The outer circumference of the main body opening upper surface portion 303 is supported by the outer circumferential side portion 304. In addition, the pot 305 is accommodated in the pot housing 302 so as to be freely detachable from above the main body, and the outer flange 306 of the pot 305 is housed in the pot housing 302 of the body 301. At this time, it is located above the main body opening upper surface portion 303.

In addition, a lid 307 covering the top of the pot 305 is located above the main body opening upper surface portion 303. In addition, the main body opening upper surface portion 303 has a rising ring-shaped ring portion 308 facing the outer circumferential flange portion 306 of the pan 305 and a rear hinge rising wall 309 for rotatably supporting the lid 307. The first cover 310 is disposed in the main body opening upper surface portion 303 including the annular ring 308.

In addition, a second cover 311 is disposed on the rear hinge rising wall 309.

Next, the function of the rice cooker is explained. The pot 305 is electromagnetically heated by the bottom coil 312, and the pot 305 is heated to cook and insulate.

Reference numeral 313 denotes a control board for controlling the heating operation of the rice cooker. Reference numeral 314 denotes a floor sensor that detects the temperature in the pan 305 at the time of cooking and warming, and transmits a signal to the control board 313.

In addition, the lid 307 is provided with an inner lid 316 having a steam hole 315 through which steam during cooking is passed. In addition, the lid 307 has a tubular steam port 317 through which the steam during cooking flows out to the outside, and the steam port 317 and the inner lid 316 are provided with a steam port packing 318 to provide steam. Is sealed so as not to flow into the lid (307).

In addition, an inner lid packing 319 disposed on the outer circumferential portion of the inner lid 316 in contact with the outer circumferential flange portion 306 of the pot 305, and the steam generated during cooking and warming is external to the steam port 317. To prevent leakage.

Steam generated during cooking and warming is attached to the inner lid 316, the steam is cooled to dew. Induction heating of the inner lid 316 with the lid coil 320 disposed in the lid in order to reduce the adhesion of the dew generated, but because the excessive heating to dry or yellow the surface of the rice, the lid coil 320 There is a limit to the electromagnetic induction heating by, so that some dew is left on the inner lid (316).

In addition, since the inner lid packing 319 is not heated again by the inner lid 316, dew is likely to adhere. When the lid 307 is opened in such a state, the dew attached to the inner lid 316 or the inner lid packing 319 falls downward, and eventually drops to the upper surface portion 303 of the main body opening of the main body 301, thereby causing dirt. Cause.

In addition, a grain of rice is attached to the main body opening upper surface portion 303, or the rice cooker is often installed around the kitchen, and is exposed to the flexibility caused by cooking using oil, so that the flexibility is attached.

In addition, the annular ring portion 308 of the upper surface portion 303 of the main body opening receives radiation heat from the outer flange portion 306 of the pot 305, and becomes 60 to 70 ° C. during cooking and 50 to 60 ° C. during warming. It becomes the temperature which is easy to breed. Thus, the dew, rice grains, or soft and seasonings attached to the main body opening upper surface portion 303 become warm to easily breed various germs, and mold, mold smell, or decaying smell are generated.

However, in the rice cooker of the present invention, a first metal cover is disposed on the main body opening upper surface portion 303 including the annular ring 308, and a second metal cover is provided on the rear hinge lift wall 309. .

For this reason, dew, rice grains, or softening dropped from the inner lid 316 and the inner lid packing 319 are attached to the second cover and accumulated on the first cover.

Here, since the first and second covers are made of metal, they are difficult to stick to, and can be easily wiped off with a cloth or the like to keep the main body opening upper surface portion 303 clean.

In addition, in the metal first and second covers, the glossiness of the metal can make the rice cooker feel clean and high-quality, thereby increasing the commercial power of the rice cooker.

Here, since the thin sheet of stainless steel and the thin sheet of aluminium are easy to process and hardly cause corrosion such as rust, it can be said that they are suitable as materials for the first cover 310 and the second cover 311.

In addition, since the second cover 311 is covered and fixed at the upper end of the first cover 310, it is assumed that an injury or the like of the first cover occurs due to the residual stress or the like caused by the press working of the first cover 310. Since it is suppressed by the 2nd cover, there also exists an effect that a problem, such as an injury, does not arise.

Here, after the toe bend 330 is inserted into the insertion hole 331 from above, the toe bend 330 can be bent using an auxiliary tool or the like to completely fix the body opening upper surface 303. By adopting such a configuration, when the toenail bent portion 330 is folded back, it can be easily taken out from the main body opening upper surface portion 303, so it is excellent in reproducibility. In addition, it can be said that the claw bending direction is preferably provided toward the inside of the product in consideration of the heat shrinkage of the upper surface portion 303 of the main body opening.

In addition, in the structure of the outer peripheral part of the main body opening upper surface part 303 in FIG. 27, the code | symbol 332 is the cross section of the main body opening upper surface part 303, and the outer peripheral cross section 332 contacts a human finger 333. In addition, in FIG. Even if the finger is bent, bending is performed. By setting it as such a structure, there is no injuries of a consumer, and it is the structure which made much of safety.

Reference numeral 307 denotes a lid, which is disposed at the upper end of the main body opening upper surface portion 303 and can be opened and closed freely. Here, the outer circumferential end portion 332 of the main body opening upper surface portion 303 is configured to be bent by 1 to 2 mm in the lid 307 and the main body opening upper surface portion 303. With such a configuration, even when the human finger 333 tries to contact the outer peripheral end portion 332 of the main body opening upper surface portion 303 during cooking, it is very difficult to make contact. There is no risk of safety and can be called a configuration that emphasizes safety.

28 is an embodiment of a method of securing the second cover to the rear hinge lift wall 309. Reference numeral 334 denotes a fixing claw disposed on the second cover, and reference numeral 335 denotes a space for securing the toenail bend. Here, the second cover 311 is provided above the rear hinge rising wall 309 to be covered by the first cover. After installation, the fixing claw 334 of the second cover is bent using an auxiliary tool or the like, and the fixing claw 334 is fixed to the space 335 by fixing. By such a configuration, even if there is no movement of the second cover in the vertical direction, even if the first cover is raised or the like due to the residual stress due to the press working of the first cover 310, the second cover is generated. It also has the effect that it does not cause problems such as injury because it is suppressed at.

In FIG. 29, reference numeral 341 denotes dew generated during cooking and warming described above, but when the lid 307 is opened, the upper portion of the upper end of the main body opening upper surface portion 303 moves along the same path as the reference numeral 342. The cover 310 and the second cover 311 are attached.

Here, the binding portion 343 of the first cover 310 and the second cover 311 is disposed above the flat portion 344 in front of the first cover 310, so that the dropped dew is flat portion 344 Since it is not accumulated above, the water is unlikely to enter the main body from the binding portion 343, and safety can be ensured.

In addition, a dew accommodating portion 345 may be disposed under the rear hinge rising wall 309 of the first cover 310 to collect the dew 341 generated by cooking and warming.

By adopting such a configuration, since the range which becomes dirty by the dew is limited to the range of the dew storage part 45, and the range which becomes dirty does not become wide, since cleaning can be simplified, the cleanability is also improved.

In such a configuration, even when the coupling portion 343 of the first cover 310 and the second cover 311 is removed to form an integrated configuration, the same effects as described above can be obtained, and the assembly performance is improved. And the reproducibility can be improved.
