Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooker and a cooking lid for cooking and cooking that can be steamed with steam generated at the same time as cooking and cooking.

[0002]

2. Description of the Related Art In cooking cooking, a cooking lid is used to suppress the emission of steam and maintain a predetermined pressure and cooking temperature. In any case, the steam is restricted but escaped to the outside. A technology for introducing steam generated in an electric rice cooker into a steamer and performing steam cooking is described in Utility Model Registration No. 3009.
912 and JP-A-63-5716. In an electric rice cooker, most of the used water is evaporated and diffused from one location of the lid to the outside, so that it is suitable for use of steam.

[0003]

However, if the steam generated at the time of cooking is used for steaming, but a single steamer is used as in the above-mentioned conventional method, a steaming container for accommodating the food is used as the steamer. In addition to the need for a lid for trapping the steam introduced into the steaming vessel, special support means such as using a suction cup to stably place the steamer on the cooking lid are required, which is complicated. In addition, it becomes expensive, and the attaching and detaching work is complicated and difficult to use. Moreover, the steamer only serves as a steamer between the cooker and the cooker.

[0004] It is an object of the present invention to provide a simple and inexpensive structure in which a cooking lid in a cooker has been improved, and that it is easy to work, and that steam cooking using steam in cooking and cooking can be performed. It is an object of the present invention to provide a cooker and a cooking lid capable of enhancing the heat retaining function of the cooker even when the cooker is not in use.

[0005]

Means for Solving the Problems In order to achieve the above-mentioned object, a cooking cooker according to the present invention has a cooking lid having a steam port for releasing steam generated during cooking to the outside, A cooking container is formed on the upper surface of the cooking lid, a steam cover is provided so as to detachably mount the cooking container and the steam port, and a steam hole is provided in the steam cover to allow steam to escape to the outside. It is characterized by the following.

[0006] In such a configuration, the steam generated by the cooker during cooking is released to the outside through the steam port of the cooking lid.
This steam escapes to the outside through the steam hole of the steam cover while first being trapped between the cooking lid and the steam cover of the cooking lid and the steam port surrounding the cooking object placement portion. Cooking is not disturbed, and when the steam is trapped in the steam cover, the food can be steamed if the food is placed on the food placing portion. In addition, since the trapping of steam in the steam cover means that the heat is trapped at the same time, it is possible to bring about a heat retaining effect of suppressing heat from easily escaping from the lid even when the food is not placed.
In addition, since it has a simple structure in which a cooking object placement part is formed on a cooking lid with a steam port and a steam cover is provided on the cooking lid so that it can be attached and detached, it is realized at low cost and easy to handle and use. It is convenient. Such a lid can be provided as a single cooker used by being detachably attached to various cooking containers, and by being detachably attached to the cooker,
Each can be washed with a steam cover.

Also, since the steam cover covers almost the entire upper surface of the cooking lid, a wider range of the upper surface of the cooking lid can be used for steam cooking, while a wider range of the cooking lid is covered with the steam cover. The above-mentioned heat retention effect can be enhanced by covering and holding steam.

If the total opening area of the steam hole is smaller than the total opening area of the steam port, the steam discharged from the steam port flows out of the steam cover while being trapped in the steam cover, but the steam from the steam port enters the steam cover. Since the resistance of the steam when flowing out of the steam hole to the outside is larger than when the steam flows out, the outflow of the steam to the outside of the steam covering can be suppressed, so that the steam can easily be trapped in the steam covering, In addition, the steam can be easily spread to all corners, and the efficiency of contacting the food placed on the food placement portion with the food can be enhanced even if the steam is discharged from one steam port. Therefore, the present invention is suitably applied to a known cooker such as an electric rice cooker or a pressure cooker having a steam port of this kind.
A pressure cooker is particularly suitable because it has a high steam temperature and has a function of dispersing released steam around.

[0009] By having a configuration in which the steam hole is located at least at a portion including the vicinity of the food storage portion and away from the steam port of the food storage portion, the steam entering the steam cover is provided. Most of the steam that has entered the steam cover flows out while contacting the food placed on the food storage part because it passes through the food storage part to let the water flow out of the steam hole to the outside. As a result, the contact efficiency of the steam with the food, that is, the steaming efficiency, can be improved.

[0010] By employing a configuration in which the food placing portion has a concave portion for receiving the food, the placed food is stabilized, so that it is easy to use without falling off.

By providing a sub-passage to the inside of the cooking lid in a part of the food placing portion, the sub-passage serves as a steam passage for allowing steam to flow directly to the food placing portion, so that the steaming efficiency is improved. Even if the condensed water or oneva that has condensed steam in the steam cover accumulates in the concave food storage section, the condensed water or oneva can be returned to the inside of the cooking lid through the sub-passage. It is possible to prevent dew water or oneva from accumulating in the storage portion and make the food sticky, and prevent the food from absorbing the dew water and becoming soaked.

[0012] By adopting a structure having an adjusting means for adjusting the opening area of the steam hole, the difficulty of the steam flowing out of the steam port and trapped in the steam cover to the outside through the steam hole, in other words, into the steam cover. , The degree of working of the steam on the cooked food can be adjusted.

The upper surface of the steam cover has an inclined surface which becomes lower from the outer periphery toward the center, and a steam hole is provided on the inclined surface. Even if dew is formed on the upper surface of the cover, the condensed water is transmitted to the central side of the steam cover, so that the water does not travel outside and wet the surroundings.

Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be used alone or in combination as variously as possible.

[0015]

The present invention can be applied to a general cooking pot or a pressure cooker for cooking and cooking, and is also effective as a single cooking lid generally used for various cooking pots and the like, and all of them belong to the scope of the present invention.

The electric rice cooker shown in FIGS. 1 and 3 has an outer case 4 made of a synthetic resin and an inner case 5 made of a metal housed inside thereof, which are connected by a shoulder member 6 made of a synthetic resin. 1. The shoulder member 6 has a fitting portion 7 which is fitted on the rim of the outer case 4 from above at the outer periphery, and the rim of the inner case 5 is applied to the inner periphery from below and is screwed with a screw 8. are doing. The bottom of the inner case 5 is screwed from the bottom of the outer case 4 through the bottom of the outer case 4 and screwed to each other by a screw 9 so that the shoulder member 6 is pulled into the outer case 4 via the inner case 5 and fixed. I have.

The heater 3 is a surface heater having a sheathed heater 12 built in a hot plate 11 made of a metal having good heat conductivity such as aluminum, and is mounted on the bottom of the interior case 5 via a heat insulating material 13. The inner pot 2 has a relatively deep shape that fits around the bottom. The depth of the heater 3 is less than about 1/3 of the depth of the inner pot 2, and is approximately 1 to the height of the rice cooking area where the inner surface of the cooking lid 14 closing the mouth of the vessel 1 and the inner pot 2 faces. / 3. Thereby, the heat of the sheath heater 12 can be widely and strongly heated at the bottom of the inner pot 2, and combined with the heating from the body heater 15 provided around the body of the interior case 5, delicious rice can be obtained. I can cook. A shoulder heater 16 is provided on the inner peripheral side of the shoulder member 6 so as to be fitted between the upper cover 17 made of metal and the lower cover 18 made of synthetic resin. On the other hand, the cooking lid 14 is provided with a metal lid 19 for heat conduction on its inner surface, and the metal lid 19 is pressed against the upper cover 17 of the shoulder heater 16 by closing the cooking lid 14, and
The heat from the shoulder heater 16 is received through the inner pan 2 and radiated from above into the inner pot 2, and is used to keep the rice warm after cooking. In order to keep the rice warm, the body heater 15 is also used, and the rice in the inner pan 2 is heated appropriately from above mainly to keep the temperature warm so that the water does not fly excessively. Of course, the heater 3 is also energized with a low energizing capacity, and can be used for heat retention by weak heating. In order to keep the temperature from being dew-condensed, care is taken to prevent a temperature difference from occurring in the inner pan 2.

The metal cover 1 is attached to a hollow lid body 25 in which an upper plate 21 and a lower plate 22 made of a synthetic resin are fitted up and down by fitting portions 23 at the inner and outer circumferences and screwed or the like.
9 in combination. The lid main body 25 can be opened and closed by rotation with respect to the shoulder member 6 by a hinge part (not shown), and is also provided with a lock member that is detachably connected and locked in a closed state. Illustration and detailed description are omitted.

The metal lid 19 is provided with a seal member 26 facing the edge of the inner pot 2. When the cooking lid 14 is closed, the seal member 26 is pressed against the edge of the inner pot 2 so that the inner lid 2 is pressed.
To the closed state. In this closed state, a steam port 31 for letting steam generated in the inner pot 2 during cooking rice escape to the outside is provided in, for example, a central portion of the metal lid 19. If necessary, it can be provided at an eccentric position. Steam port 3 in electric rice cooker
1 is to limit the escape of steam to the outside.
It has a so-called pressure regulation function that adjusts the inside to a pressure suitable for cooking rice. The restriction on the release of the steam to the outside is provided by providing a steam valve 32 that closes by its own weight in the steam passage 31a of the steam port 31, and the steam 41 is closed only when the pressure in the inner pan 2 is higher than a predetermined value.
Presses the steam valve 32 open and flows out. The steam passage 31a has an appropriate passage cross-sectional area and an opening area to the outside that pushes the steam valve 32 open and flows out, and that emits the oneva flowing out along with the steam 41 without strongly scattering it around. And designed to have.

Specifically, the steam outlet 31 is screwed to the upper surface of the metal cover 19 with a screw 33 and provided through a through hole 36 provided in the cover body 25 to the upper surface of the cover body 25.
5a has a steam port body 35 made of a synthetic resin, and the steam port body 35 communicates with the steam discharge port 35a from the inside of the inner pot 2 through the steam outlet hole 19a of the metal lid 19 and the oneva pool 40 thereabove. A steam passage 31a is formed, and a steam valve 32 is inserted into a steam passage 31a having a valve retaining rib 31c thereon through an extension 31b provided at a lower portion of the steam passage 31a, so that the steam passage 31a, the extension 31b The steam valve 32 closes the valve port 34a of the valve seat plate 34 by its own weight by receiving it from below with a valve seat plate 34 fixed by welding or the like against the downward step surface 31c. The reason why there are a plurality of vapor discharge ports 35a is to disperse the released vapor, and basically one vapor discharge port may be provided. An elastic member 37 made of silicon rubber or the like is provided on the outer periphery of the steam port main body 35 by fitting it into the groove 38. The elastic member 37 and the opening edge 22 a of the lower plate 22 of the lid main body 25 are elastically fitted. The metal lid 19 can be opened and closed integrally with the lid main body 25, and can be handled.
Is handled by itself, so that it can be washed. By removing the cooking lid 14 from the container 1, each of the lid main body 25 and the metal lid 19 can be handled independently, and the whole can be washed.

On the upper surface of the lid body 25, that is, around the through hole 36 facing the steam port 31 on the upper surface of the cooking lid 14,
The inclined surface 25a becomes lower toward the through hole 36, and the oneva that has flowed out together with the dew condensation water or steam condensed around the opening of the through hole 36 flows toward the through hole 36 to form the steam port 31.
And flows down from the gap 36a. Therefore, the metal lid 19 is formed in a shape having a concave portion forming an oneva reservoir 40 on the upper surface, and the oneva reservoir 40 receives the oneva flowing through the steam outlet hole 19a and the dew water or oneva flowing down the through hole 36. I'm trying to store. At the same time, a sealing member 39 sandwiched between the upper plate 21 and the lower plate 22 is provided on the lower surface of the outer peripheral portion of the lid main body 25, and is pressed against the outer periphery of the metal lid 19 to seal between them. In addition, the vapor 41 entering the oneva pool 40, the dew condensation water and the oneva stored therein are prevented from flowing out. Oneva pool like this 4
Even if dew condensation water or oneva accumulates at 0, the lid main body 25 and the metal lid 19 can be easily cleaned including the through hole 36 and the steam port 31 by separately washing the whole with the metal lid 19. The lower surface of the lower plate 22 is covered with a metal plate 30 and a gap 20 is provided in a portion except for the inner and outer peripheral portions between the lower plate 22 and the metal plate 30, so that the lower plate 22 is exposed to steam or heat. Is prevented.

In such an electric rice cooker, the steam generated during cooking and released to the outside from the steam port 31 as described above is effectively used for steaming cooking. In each of the embodiments shown in FIGS. 3 and 4, a cooking object placing portion 42 is formed on the upper surface of the cooking lid 14 having the steam port 31 for allowing the steam 41 generated during cooking to escape to the outside. A steam cover 43 is provided to surround the mounting portion 42 and the steam port 31 so as to be detachable.
Is provided with a steam hole 44 for allowing the air to escape to the outside. As a result, the electric rice cooker allows steam 41 generated during cooking to escape from the steam port 31 of the cooking lid 14 to the outside.
First, the steam cover 43 surrounding the cooking port 42 and the steam port 31 in the cooking lid 14 is evacuated to the outside through the steam hole 44 of the steam cover 43 while being squeezed first. Therefore, it does not disturb the normal rice cooking by the electric rice cooker. When the steam 41 is trapped in the steam cover 43 and the food 45 such as an egg is placed on the food placing portion 42, the steam is steamed. You can raise it, and if it's an egg, you can make a boiled egg.

Also, since the steam 41 is trapped in the steam cover 43 at the same time that heat is trapped therein,
Can prevent the heat from escaping easily from the lid even when it is not placed.
1 is effectively used. Further, a cooking object placing portion 42 is formed on the cooking lid 14 having the steam port 31 and the steam cover 4 is formed thereon.
Since it has a simple structure in which it is only provided so that it can be attached and detached, it can be realized at low cost, and is easy to handle and convenient to use. Further, such a lid structure can be provided and used as a single cooker that is detachably used in various cookers. Also, as shown in FIGS. 1 to 4, the steam cover 43 covers almost the entire upper surface of the cooking lid 14, so that a wider range of the upper surface of the cooking lid 14 can be used for steam cooking. By covering a wider area of the cooking lid 14 with the steam cover 43 and trapping the steam 41, the above-mentioned heat retaining effect can be enhanced.

It is preferable that the total opening area of the steam holes 44 is set to be smaller than the total opening area of the steam discharge ports 35a in the steam port 31. With this configuration, the steam 41 that has exited from the steam port 31 flows out of the steam cover 43 through the steam hole 44 while being trapped in the steam cover 43, but the steam flows out of the steam port 31 into the steam cover 43. Also, the outflow of the steam 41 can be suppressed by an amount corresponding to the greater resistance when the steam flows out from the steam hole 44 to the outside, so that the steam 41 can be easily trapped in the steam cover 43, and the steam can be spread to every corner. You can get around. Therefore, even if the food 45 placed on the food placing part 42 is the steam 41 flowing out from one steam port 31, the contact efficiency with the food 45 can be increased, and thus such a steam port 31 is used. It is suitable to be applied to a cooker such as a pressure cooker in addition to the electric rice cooker as in the present embodiment having one. A pressure cooker is particularly suitable because it has a high steam temperature and has a function of dispersing released steam around.

As shown in FIGS. 1 to 4, the steam hole 44 is located at least at a part including the vicinity of the food placing portion 42 and a portion away from the steam port 31 of the food placing portion 42. I have to do it. In these embodiments, since the steam port 31 is provided at the central portion of the cooking lid 14 and the food placing portion 42 is provided around the outside, the steam port 4 is provided.
Reference numeral 4 includes at least the food placing portion 42 and is provided on at least a part of a portion on the outer peripheral side of the portion 42. Thereby, the steam 41 that has entered the steam cover 43
Is allowed to flow out of the steam hole 44 to the outside through the food placing portion 42. Therefore, most of the steam 41 that has entered the steam cover 43 flows out to the outside while being in contact with the food 45 placed on the food placing portion 42, so that the efficiency of contact of the steam 41 with the food 45 is increased. That is, the steaming efficiency can be increased. In addition, the steam port 31 is the cooking lid 1
4 is provided eccentrically to one side.
The above condition can be satisfied by providing the position 4 eccentrically on the opposite side of the food placing portion 42, so that a wide portion between the steam port 31 and the steam hole 44 eccentric on both sides can be satisfied. By providing the food placing portion 42, the steam 41 can be efficiently brought into contact with the food 45 placed there.

Further, as shown in FIGS. 1 to 4, the food placing portion 42 has a concave portion for receiving the food 45.
Since the placed food 45 is stabilized with eggs or the like, it becomes easy to use without falling off. In particular, in the embodiment shown in FIGS. 1 to 4, the concave shape is a ring shape concentric with that around the steam port 31.
The food 4 which is easy to roll by forming a seat 42a for receiving
Even with 5, the steam cooking can be performed stably in a predetermined direction. However, the present invention is not limited to these forms. In the case where the steam port 31 and the steam hole 44 are distributed to both sides as described above, a dish-shaped recess may be formed between them. . Further, depending on the case, an auxiliary receiver for stabilizing eggs or the like individually or in several portions in one concave portion of the food placing portion 42 may be used. In short, the food placing section 42 may take any form as long as the food 45 can be stably placed and used for steam cooking.

Further, a sub-passage 46 communicating with the inside of the cooking lid 14 is provided in a part of the food placing portion 42 forming a concave portion. In the embodiment shown in FIGS. 1 to 4, the passage 41 is provided so as to communicate with the inner pot 2 through the hole 47 of the metal lid 19, and the sub passage 46 serves as a passage for allowing the steam 41 to flow directly to the food placing portion 42. While increasing the steaming efficiency, even if dew condensation water or oneva which dewed steam 41 in the steam cover 43 accumulates in the food storage portion 42 forming the concave portion, the dew water or oneva is conveyed to the cooking lid 14 through the sub passage 46. Since the food can be returned to the inside, it is possible to prevent the dewed water or oneva from accumulating in the depot 42 and make the food 45 sticky or prevent the food 45 from absorbing the dewed water and becoming soggy. However, the sub passage 46
May be provided so as to open to the oneva pool 40 formed by the metal lid 19. In this case, the dew condensation water and the oneva stored in the food placing portion 42 are returned to the oneva pool 40 and stored therein. 2 can be prevented from returning.

Further, in the embodiment shown in FIGS. 1 to 4, the upper surface of the steam cover 43 becomes lower from the outer periphery toward the center.
3a, and a steam hole 44 is provided on the inclined surface 43a. As a result, even if the steam 41 flowing out from the steam hole 44 to the upper surface of the steam cover 43 is condensed on the upper surface of the steam cover 43, the condensed water is transmitted to the center side of the steam cover 43 and thus flows outward. It doesn't fall and get wet around you. In addition, the lowest part 4 of the inclined surface 43a
3d has a vapor hole 44, and the center side is higher from the lowest part 43d. As a result, the steam hole 44 in the lowest portion 43d normally causes the condensed water condensing on the upper surface of the steam cover 43 to flow along the inclined surface 43a while flowing the steam 41 trapped in the steam cover 43 to the outside. Store in 43d,
The condensed water collected in the lowest part 43d is transferred to the steam hole 4 there.
4 can be returned into the steam cover 43. In particular,
In the embodiment shown in FIGS. 1 and 2, the lowest portion 43 d is located at a position corresponding to the food placing portion 42, and the dew condensation water returned from the steam hole 44 of the lowest portion 43 d to the inside of the steam cover 43 is used for cooking. It is dropped and received on the object placing portion 42 and returned to the inside of the cooking lid 14 through the sub passage 46. 3 and 4
In the embodiment shown in FIG. 4, the lowest part 43d corresponds to the inclined surface 25a around the through hole 36, and the dew condensation water returned from the steam hole 44 of the lowest part 43d to the inside of the steam cover 43 is on the inclined surface 25a. After being dropped and received, it is guided to the through hole 36 and reaches the oneva pool 40 of the metal lid 19 and is stored there.
