  The present invention is provided with a handle on the upper surface side of the lid body, and using the handle, a lid for a cooking container that can freely open and close an upper opening of a cooking container in which a cooking space is formed, and a lid for the cooking container Related to cooking utensils.

Such a cooking utensil has a generally bottomed cylindrical cooking container with a cooking space formed therein and an upper opening, and a cooking container on the lower surface side of the lid body by gripping a handle provided on the upper surface side of the lid body. And a cooking container lid that can be freely opened and closed.
As a cooking utensil, for example, as shown in Patent Document 1, a main body having a heating unit such as an electric heater, a cooking plate (an example of a cooking container) housed in the main body, and a lid that closes an upper opening of the cooking plate ( An example of a grill pan provided with a cooking container lid), or, for example, as shown in Patent Document 2, a pan (an example of a cooking container) and a lid that closes an upper opening of the pan (an example of a cooking container lid) The thing provided with can be illustrated. In addition, although the grill pan as a cooking appliance is an example of an electric heating cooker, a hot plate, a home bakery, etc. other than a grill pan can be illustrated as the said electric heating cooker.

  Here, for example, as shown in Patent Documents 1 and 2, the cooking state of the cooked material such as ingredients cooked in the cooking space of the cooking container with the upper opening of the cooking container closed by the lid for the cooking container In order to make these visible, it is performed that the lid for the cooking container is made of a transparent member such as tempered glass. However, when the cooked food in the cooking space is heated, steam is generated from the cooked food, and the steam adheres to the lower surface of the lid for the cooking container that bulges upward toward the upper side. There has been a problem that the visibility of the transparent member constituting the container lid is very low because the lower surface of the transparent member becomes cloudy or drops adhere to the lower surface.

  For this reason, in Patent Document 1, a wiper that slides in contact with the lower surface of the cooking container lid is provided on the cooking container lid, and droplets attached to the lower surface of the cooking container lid by sliding the wiper are removed. It is set as the structure which prevents the fall of visibility by removing.

Furthermore, by providing conical protrusions as a plurality of droplet guiding elements on the lower surface of the cooking container lid, when the vapor adhering to the film on the lower surface becomes droplets, the droplets become protrusions. It is set as the structure which is guide | induced and dripped below (in cooking space). That is, the lowering of the visibility of the portion (excluding the portion where the protrusion is formed) on the lower surface of the cooking container lid is prevented, and the inside of the cooking space can be visually recognized from above through the portion. ing.

JP-A-6-237867 JP 2011-239999 A

  In the configuration disclosed in Patent Document 1, since it is necessary to provide a wiper separately, the number of parts increases and the configuration becomes complicated. In addition, since it is necessary to start or stop the wiper sliding, an extra operation is required. It becomes necessary.

  In addition, in the configuration disclosed in Patent Document 2, it is necessary to coat the lower surface of the cooking vessel lid with a metal oxide or the like as a hydrophilic treatment, and to provide a conical protrusion. This increases process complexity and manufacturing costs. On the other hand, if the coating is not performed, it is difficult to prevent the visibility of the cooking container lid from being lowered.

  The present invention has been made in view of such circumstances, and its purpose is to prevent fogging of a viewing window made of a transparent member and generation of liquid droplets with a simple configuration and without requiring special operation. In addition to being able to provide a lid for a cooking container and a lid for the cooking container that allows the cooked food in the cooking space to be satisfactorily visually recognized through the visual window even when fogging or droplets occur It is to provide cooking utensils.

The lid for a cooking container according to the present invention for achieving the above object comprises a handle on the upper surface side of the lid body, and the upper opening of the cooking container in which a cooking space is formed can be opened and closed with the handle. The cooking container lid has a characteristic configuration
The lid body is formed with a convex bulge that bulges from the lid body toward one point on the lower side, and all or part of the convex bulge is composed of a transparent member,
In the closed posture in which the upper opening is closed on the lower surface side of the lid body, the portion made of the transparent member of the convex bulge is configured as a viewing window for viewing the inside of the cooking space. It is in.

  According to the above characteristic configuration, the lid body of the cooking container lid is formed with a convex bulging portion that bulges from the lid body toward one point on the lower side, and all or part of the convex bulging portion is formed. In a closed position in which the upper opening of the cooking container is closed by the lower surface side of the lid body with the handle positioned on the upper surface side of the lid body, the portion made of the transparent member of the convex bulging portion Since it is configured as a viewing window for viewing the inside of the cooking space from the upper side, it has a simple structure and does not require special operation, and the viewing window made of a transparent member has good fog and generation of droplets In addition to being able to be prevented, it is possible to satisfactorily visually recognize a cooked item such as food in the cooking space through the viewing window even if fogging or droplets are generated.

In other words, when the cooking container lid is set to the above-described closed position and the food contained in the cooking space of the cooking container is heated, the steam generated from the food rises and reaches the lower surface of the lid body. At this time, the steam is guided upward along the lower surface of the convex bulging portion that bulges from the lid main body toward one point on the lower side, and around the convex bulging portion on the lower surface of the lid main body. Will reach and spread. For this reason, the lower surface of the convex bulging portion of the lid body is a portion to which liquid droplets due to the vapor are difficult to adhere, and all or part of the portion (convex bulging portion) is made of a transparent member. By configuring the part to be a viewing window for visually recognizing the inside of the cooking space, it is possible to make it difficult for liquid droplets to adhere to the viewing window (transparent member). The convex bulging portion that bulges from the lid body toward one point on the lower side is a configuration in which at least the lower surface of the convex bulging portion bulges toward one point on the lower side from the lower surface of the lid body. For example, in a cross-sectional view, the lower surface of the convex bulge is configured by a part of a circle, a part of an ellipse, a part of a triangle, a part of a quadrangle, a part of a polygon, and the like.
In addition, even if liquid droplets adhere to the lower surface of the viewing window (transparent member), the viewing window has a convex bulge that bulges from the lid body toward a point on the lower side of the lid body. Because it is all or part of it, moving the liquid droplets to a point on the lower side along the lower surface of the convex bulge makes it easy to make the viewing window wet. Since it is easy to do, it becomes a big droplet and it becomes easy to be dripped below (in cooking space).
Therefore, it is a simple configuration and does not require any special operation, so that the visible window (transparent member) formed on all or part of the convex bulging portion of the lid body of the cooking container lid is free of fogging and droplets. In addition to being able to prevent generation well, even if fogging or droplets occur, the effects of fogging and droplets on the viewing window can be reduced, and the visibility of the viewing window can be improved. Thus, the cooked food in the cooking space can be viewed well through the viewing window.

  A further characteristic configuration of the lid for a cooking container according to the present invention is that a portion other than the viewing window in the lid body is formed of an opaque metal member.

  According to the above characteristic configuration, the portion other than the viewing window in the lid body is formed of an opaque metal member, so that only the viewing window forming portion necessary for visually confirming the cooking space is relatively heavy. It can be constituted by a transparent member such as tempered glass, and the other parts can be constituted by a relatively light metal member, so that the weight of the entire lid body can be reduced. Further, steam generated from the food is guided upward along the lower surface of the convex bulge portion, and around the convex bulge portion on the lower surface of the lid body (at least around the visual recognition window made of a transparent member). Since the metal member reaches and diffuses, the temperature of the metal member can be kept high, and the cooking performance of the food existing below the metal member can be improved.

  A further characteristic configuration of the lid for a cooking container according to the present invention is such that the thickness of the transparent member constituting the viewing window is configured to be constant or substantially constant, and in the closed position, the viewing window is on the cooking space side. It is in the point comprised as all or one part of the recessed part dented in.

  According to the above characteristic configuration, since the thickness of the transparent member constituting the viewing window is configured to be constant or substantially constant, the transparent member constituting the viewing window can be easily manufactured. The distortion of the image when visually recognizing the inside of the cooking space can be prevented. Furthermore, since the whole or part of the concave portion is formed in a state where the thickness of the transparent member constituting the viewing window is constant or substantially constant, the weight of the transparent member can be reduced.

  The further characteristic structure of the cooking container lid which concerns on this invention exists in the point by which the said visual recognition window is formed in the center part of the said lid main body by planar view.

  According to the above characteristic configuration, since the visual recognition window is formed in the central portion of the lid body, when the cooking space is visually recognized from the upper side of the lid main body through the visual recognition window, only the cooked food present in the central portion of the cooking space. In addition, the cooked food present on the outer side than the central portion can be easily visually recognized.

  A further characteristic configuration of the cooking container lid according to the present invention is such that the convex bulging portion is formed in a circular shape or an elliptical shape in a bottom view, and the lower surface of the convex bulging portion is a sectional view. Thus, it is a point formed by a convex curve that bulges toward one point on the lower side.

According to the above characteristic configuration, the lower surface of the convex bulging portion has one curved surface (a convex curved surface that bulges downward or a downward depression) that radiates upward from the lowermost point of the lower surface over the entire circumference. A concave curved surface). In this case, the lower surface of the convex bulging portion is constituted by, for example, a part of a circle and a part of an ellipse in a sectional view.
Thereby, when the steam generated from the cooked food in the cooking space rises and reaches the lower surface of the convex bulging portion, the steam radiates from one point at the bottom of the curved surface on the lower surface of the convex bulging portion. In addition, the air smoothly flows upward along the curved surface, and flows outward toward the space around the convex bulging portion. Therefore, the generated steam convects and diffuses radially upward and outward along the lower surface of the convex bulge, and the steam stays in the convex bulge, particularly in the vicinity of the viewing window. It is possible to prevent the vapor from adhering to the vicinity of the viewing window or to form droplets. Moreover, since the lower surface of the convex bulging portion constitutes one curved surface (a part of a sphere or a part of an ellipsoid), the visibility of the viewing window can be improved.

  A further characteristic configuration of the lid for a cooking container according to the present invention is such that, in the closed position, the lowermost portion of the convex bulge portion comes into contact with the cooking container formed on the outer peripheral portion of the lower surface of the lid body. The point is located above the surface.

  According to the above characteristic configuration, in the closed posture in which the upper opening is closed on the lower surface side of the lid body, the lowermost portion of the convex bulge portion contacts the cooking container formed on the outer peripheral portion of the lower surface of the lid body. Since it is located above the surface, even if there is a convex bulging portion that bulges downward (cooking space side) on the lower surface of the lid body, it is possible to prevent a reduction in the volume of the cooking space, Many cooking items can be accommodated in the cooking space.

  A further characteristic configuration of the lid for a cooking container according to the present invention is that a portion other than the viewing window in the lid body is formed of an opaque metal member, and the handle is provided on the upper surface side of the metal member.

  According to the above characteristic configuration, since the handle is provided on the metal member that constitutes the portion other than the viewing window in the lid body, the handle may be an obstacle when the inside of the cooking space is viewed through the viewing window. In addition, since the handle is provided on the upper surface side of the metal member in the lid body, the lid body can be used to open and close the upper opening of the cooking container. It can be done reliably.

  A further characteristic configuration of the cooking container lid according to the present invention is that the transparent member is configured to be detachable from the lid body.

  According to the above characteristic configuration, since the transparent member is configured to be detachable from the lid main body, the transparent member can be detached as necessary, and convenience can be improved. For example, during cooking, when you want to visually check the cooking space directly while minimizing temperature drop in the cooking space, or when you want to add seasonings to the food, etc., the lid body remains in the closed position, Since only the transparent member can be removed from the lid body, convenience can be improved.

  In order to achieve the above object, a cooking utensil according to the present invention comprises the cooking container lid according to any one of the above characteristics and the cooking container having the upper opening that can be opened and closed by the cooking container lid. It is in the point.

  According to the above characteristic configuration, the cooking utensil can close the upper opening of the cooking container with the cooking container lid having the above-described configuration. Therefore, in the cooking utensil, steam generated from the cooked food in the cooking space of the cooking container is used. Can effectively prevent fogging of the viewing window and droplets from being generated, and even if fogging or droplets of the viewing window occur, the effects of fogging and droplets on the viewing window can be reduced. By improving the visibility, the cooked food in the cooking space can be seen well through the viewing window.

A heat shield plate 7 having a bottom portion 7a and a side wall portion 7b formed in substantially the same shape as the main body portion 3 is disposed on the upper surface of the bottom portion 3a. The outer diameter of the side wall 7b of the heat shield 7 is formed to be slightly smaller than the inner diameter of the side wall 3b of the main body 3, and the height of the side wall 7b is formed to be lower than the height of the side wall 3b. ing.
In addition, an electric heater 6 made of a heating wire bent in a planar shape is provided on the upper surface of the bottom portion 7a of the heat shield plate 7 provided in the main body 3, and the electric heater 6 on the upper surface of the bottom portion 7a. On the outer peripheral side (between the bottom part 7a and the side wall part 7b) from the arrangement location of the cooking plate mounting step part 7c located above the upper end part of the electric heater 6 is provided.

  The cooking plate 4 is formed in a substantially oval shape in a plan view, and has a substantially dish shape (an example of a bottomed cylindrical shape) including a bottom portion 4a and a side wall portion 4b extending upward on the outer peripheral side of the bottom portion 4a in a cross-sectional view. The upper opening 4c having a substantially elliptical shape is formed on the inner peripheral side of the side wall 4b. Therefore, a cooking space S surrounded by the bottom 4a and the side wall 4b and having an upper side opened by the upper opening 4c is formed in the cooking plate 4.

  At the upper end portion of the side wall portion 4b of the cooking plate 4, a flange portion 4d extending outward (horizontal direction) is formed over the entire circumference. Further, the pair of short sides of the side wall 4b of the cooking plate 4 extend inward (upward opening 4c side) at a position below the upper surface of the flange 4d over substantially the entire length thereof. A pair of lid placing steps 4e is provided. Thereby, although mentioned later for details, it is comprised so that the lid | cover 5 can be mounted on the upper surface of the step part 4e for lid | cover mounting.

  The outer diameter of the side wall 4b of the cooking plate 4 is slightly smaller than the inner diameter of the side wall 7b of the heat shield plate 7, and the outer diameter of the flange 4d of the side wall 4b is larger than the outer diameter of the side wall 7b. And the height of the flange 4d of the side wall 4b is higher than that of the side wall 7b and lower than that of the side wall 3b. Thereby, the cooking plate 4 is placed in a state where the bottom surface 4a of the cooking plate 4 is placed on the cooking plate placement step 7c of the heat shield 7 and close to the electric heater 6, and The heat shield plate 7 is disposed inside. Further, in this state, the flange portion 4 d of the side wall portion 4 b of the cooking plate 4 is configured to be located above the side wall portion 7 b of the heat shield plate 7 and below the side wall portion 3 b of the main body portion 3. Has been.

  The lid 5 includes a lid body 5A and a handle 5B on the upper surface side of the lid body 5A, and the upper opening 4c of the cooking plate 4 in which the cooking space S is formed can be freely opened and closed using the handle 5B. It is configured.

  The lid body 5A is formed in a substantially oval shape that is substantially the same shape as the cooking plate 4 in plan view, but the outer diameter of the lid body 5A is slightly smaller than the inner diameter of the side wall portion 4b of the cooking plate 4 and is mounted on the lid. It is formed in a size that can be placed on the upper surface of the mounting step 4e. The lid body 5A is made of a metal member (for example, aluminum).

  Further, the lid main body 5A is formed so as to bulge out in a convex shape (convex shape on the upper surface side) as a whole in a cross-sectional view, and the outer peripheral portion 5a becomes the lower end. Accordingly, the lower surface of the outer peripheral portion 5a of the lid body 5A (an example of a contact surface with the cooking plate) is placed on the upper surface of the lid placing step portion 4e of the cooking plate 4 and above the cooking plate 4. The opening 4c can be closed. That is, the lid 5 is in a closed posture in which the upper opening 4c of the cooking plate 4 is closed on the lower surface side of the lid body 5A. In this closed position, the lid 5 is positioned with respect to the cooking plate 4 to prevent relative movement inward and outward.

The lid main body 5A is formed with a convex bulging portion 5b that bulges from the lid main body 5A toward one point on the lower side, and the convex bulging portion 5b is formed in a circular shape in plan view and bottom view, It is formed in the central part of the lid body 5A in a plan view and a sectional view. Each of the upper surface and the lower surface of the convex bulging portion 5b is formed by a convex curve (a part of an ellipse) that bulges toward one point on the lower side in a sectional view. That is, each of the upper surface and the lower surface of the convex bulging portion 5b is formed by a part of an ellipsoid that is one curved surface.
Further, the entire convex bulging portion 5b is composed of a transparent member C, and this transparent member C has a predetermined constant thickness (approximately the thickness other than the portion where the convex bulging portion 5b is formed in the lid body 5A). The same thickness) of tempered glass. Although illustration is omitted, the transparent member C is fixed to the lid body 5A by a known fixing means. In addition, although the thickness of the transparent member C is made constant, the thickness of the transparent member C may be configured by a substantially constant thickness that is slightly different depending on the part. Moreover, the transparent member C does not need to be tempered glass as long as it is transparent, and can be composed of heat-resistant glass, resin, or the like.
In the closed posture in which the upper opening 4c is closed on the lower surface side of the lid body 5A, the lowermost portion of the convex bulge portion (transparent member C) 5b is a contact surface with the lid mounting step 4e. The curvature of the curved surface of the convex bulging portion (transparent member C) 5b is set so as to be located above the lower surface of the outer peripheral portion 5a of 5A. Therefore, even when there is a convex bulging portion 5b that bulges downward (cooking space S side) on the lower surface of the lid body 5A, the volume of the cooking space S can be prevented from decreasing, and the cooking space S can be reduced. It can accommodate many dishes.

And in this embodiment, the convex bulging part (transparent member C) 5b provided in the lid body 5A in this way is configured as a visual recognition window W for visually recognizing the cooking space S of the cooking plate 4. is there.
Accordingly, since the portion other than the visual recognition window W in the lid main body 5A is formed of an opaque metal member, only the portion of the lid main body 5A where the visual recognition window W is formed is formed by a transparent member C such as a relatively heavy tempered glass. It can comprise, and a site | part other than that can be comprised with a comparatively light metal member, and can achieve weight reduction in the whole lid body 5A. The transparent member C constituting the viewing window W is configured to have a constant thickness, and in the closed position, the recessed portion in which the viewing window W is recessed toward the cooking space S (the convex bulging portion 5b that bulges downward). ), The transparent member C constituting the viewing window W can be easily manufactured, and the distortion of the image when the inside of the cooking space S is viewed through the transparent member C can be prevented. it can. Moreover, since the whole of the concave portion (the convex bulging portion 5b bulging downward) is formed in a state where the thickness of the transparent member C constituting the viewing window W is constant, the weight of the transparent member C is reduced. be able to. Furthermore, since the visual recognition window W is formed in the central part of the lid body 5A in plan view, when the cooking space S is visually recognized from the upper side of the lid main body 5A through the visual recognition window W, the central part of the cooking space S is displayed. As well as the cooked food present at the center, the cooked food present on the outer side of the central portion can be easily visually recognized.

  The handle 5B is provided in the central portion on the upper surface side of the lid body 5A, that is, the central portion on the upper surface side of the convex bulge portion (transparent member C, viewing window W) 5b, and from the lower surface side to the upper surface side of the transparent member C. It is fixed to the transparent member C by a screw (not shown) penetrating through the transparent member C.

  Next, when cooking a cooked material (not shown) such as food in the cooking space S of the cooking plate 4 using the hot plate 1 having the above-described configuration, steam (not shown) generated from the cooked product is used. In addition to being able to satisfactorily prevent fogging and droplets from being generated in the viewing window W provided on the lid 5, even when fogging or droplets are generated, The point which can visually recognize this cooking thing favorably is demonstrated.

First, after the cooked food is stored in the cooking space S of the cooking plate 4 placed in the main body 3, the handle 5 </ b> B of the lid 5 is gripped, and the outer peripheral portion 5 a of the lid main body 5 </ b> A is covered with the cooking plate 4. It mounts on the mounting step 4e, and the lid 5 is set to a closed posture in which the upper opening 4c of the cooking plate 4 is closed.
Then, when the food in the cooking space S is heated by the electric heater 6, the steam generated from the food rises and reaches the lower surface of the lid body 5A. At this time, the steam is guided upward along the lower surface of the convex bulging portion 5b bulging from the lid main body 5A toward one point on the lower side, and the convex bulge on the lower surface of the lid main body 5A. It will reach and diffuse around the part 5b. That is, the steam smoothly flows radially from one point at the bottom of the curved surface on the lower surface of the convex bulging portion 5b and upward along the curved surface, and the space around the convex bulging portion 5b. To the outside. Accordingly, the generated steam convects and diffuses radially upward and outward along the lower surface of the convex bulging portion 5b, and the convex bulging portion (transparent member C) 5b, particularly the viewing window W. It is possible to prevent the steam from staying in the vicinity.

  Thereby, the lower surface of the convex bulging portion 5b of the lid main body 5A becomes a portion to which liquid droplets due to the vapor hardly adhere, and the entire portion (convex bulging portion 5b) is constituted by the transparent member C, and the transparent By configuring the portion made of the member C as a visual recognition window W for visualizing the inside of the cooking space S, it is possible to prevent the vapor from adhering or forming droplets in the vicinity of the visual recognition window W. It can be set as the structure which the droplet by vapor | steam does not adhere easily to the window (transparent member C) W.

  Further, even if a droplet adheres to the lower surface of the viewing window (transparent member C) W, the viewing window W protrudes from the lid body 5A toward the lower point on the lower surface of the lid body 5A. Since it is the bulging portion 5b, moving the liquid droplets to a lower point along the lower surface of the protruding bulging portion 5b and collecting them makes it easy to bring the viewing window W into a wet state. Since the droplets are easy to coalesce, they become large droplets and can be easily dropped downward (in the cooking space S).

  Therefore, in the hot plate 1 provided with the lid 5, a visual recognition window (transparent) formed on the entire convex bulging portion 5b of the lid body 5A of the lid 5 with a simple configuration and does not require any special operation. Member C) In addition to being able to satisfactorily prevent clouding of W and generation of liquid droplets, even if clouding or liquid droplets are generated, the effects of clouding and liquid droplets on the viewing window W can be reduced. In addition, by improving the visibility of the visual recognition window W, the cooked food in the cooking space S can be favorably visually recognized through the visual recognition window W.

For example, as shown in FIG. 6, a convex bulging portion 50 bulging from the lid main body 5A toward one point on the lower side is provided at a position biased outward from the central portion of the lid main body 5A. The entire convex bulging portion 50 may be configured as the transparent member C, and the portion formed by the transparent member C may be configured as the visual recognition window W. 6 is formed in a circular shape (a part of a circle in a cross-sectional view) in a plan view, the shape is elliptical in a plan view (one of the ellipses in a cross-sectional view). Part) etc., and the number is not limited to one, but a plurality of positions can be provided as shown in FIG.
For example, as shown in FIG. 8, a convex bulging portion 51 bulging from the lid main body 5A toward one point on the lower side is provided at the center of the lid main body 5A. Only a portion near the center of the transparent member C (only a donut-shaped ring-shaped portion in plan view) is made of a transparent member C, and other portions are made of an opaque metal member. May be configured as the viewing window W.
Furthermore, for example, as shown in FIG. 9, a convex bulging portion 51 bulging from the lid main body 5 </ b> A toward one point on the lower side is provided at the center of the lid main body 5 </ b> A. The transparent member C is configured by forming only a part (only a schematic arc-shaped part or a band-shaped part in a plan view) that is biased outward from the center of the transparent member C and the other part by an opaque metal member. You may comprise only the site | part formed by the visual recognition window W. FIG.

(E) In the above embodiment, the lid body 5A of the lid 5 is configured by the transparent member C and the opaque metal member. However, all or part of the convex bulging portion 5b of the lid body 5A is configured by the transparent member C. As long as the viewing window W is configured, parts other than the viewing window W may be configured by the transparent member C. That is, the entire lid body 5A of the lid 5 may be configured by the transparent member C.

(F) In the above embodiment, in the closed posture in which the upper opening 4c is closed on the lower surface side of the lid body 5A, the lowermost portion of the convex bulge portion (transparent member C) 5b is the lid mounting step 4e. The curvature of the curved surface of the convex bulge portion (transparent member C) 5b is set so as to be located above the lower surface of the outer peripheral portion 5a of the lid body 5A that is the contact surface of The lowermost portion of the portion (transparent member C) 5b may be configured to be located at the same position as or below the lower surface of the outer peripheral portion 5a of the lid body 5A that is a contact surface with the lid mounting step 4e.
