Description

  The present invention relates to a steamer, more specifically, a steamer having a metal steaming container having a steam hole for passing steam at the bottom, and a lid for closing the opening of the steaming container. It is related with the steamer which attached the handle made from a non-metal having.

  This type of steamer is generally placed on a cooker body that generates steam by being heated by an open flame as disclosed in Patent Document 1 below, and the generated steam is placed in the bottom steam hole. The food is stored in a closed space with a lid, and the stored food is steamed. Even during cooking, the steamer is removed to check the remaining amount of water in the cooker body and to supply water, so the steamer in a high temperature state is handled by hand. The same is true even when steamed. For such handling, the steamer described in Patent Document 1 is attached so that a heat-insulating one-handed handle can be attached to and detached from the outer periphery of the opening of the steaming container by a metal connecting part, and is thermally safe. Is secured so that it can be handled. In addition, a steam escape opening is formed in the upward step formed on the interruption of the peripheral wall of the cooker body so that the steam in the cooking container is blown outward and downward around the cooking container, and a blowout directed toward the handle is made. It is preventing.

  On the other hand, in Patent Document 2 below, an outwardly projecting portion is provided at an appropriate number around the flange of the opening of the steaming container, and a heat insulating container handle is insert-molded on the projecting portion. It is attached. In addition, a heat-insulating lid handle is insert-molded on the overhanging portion provided at appropriate locations on the outer periphery of the lid, and the lid handle is placed on the container handle via the positioning engagement portion, and the container body and the lid are placed. A gap is formed in the circumferential area outside the container handle and lid handle engagement area to release steam to the outside, and the discharged steam passes through the side of the lid handle and container handle so that it can be handled by the container handle. The above thermal safety is aimed at.

  On the other hand, although not hitting a steamer, techniques for providing a heat-insulating handle around the outside of the opening of the container in order to ensure thermal safety in handling can also be seen in Patent Documents 3 and 4 below. Patent document 3 forms the handle located in the flange overhang | projection area under the outward flange formed in the opening part in the pan of the rice cooker in two places in the circumferential direction of the annular member fitted to the outer periphery of the pan. The technique of welding the handle part to the upper part of the peripheral wall of the pan and screwing it to the mounting bracket is disclosed, and the overhang of the handle is suppressed.

  Patent Document 4 describes a cooking board for an electric heating cooker, in which a heat-insulating handle that surrounds the outer periphery of the opening is provided with a gap between the cooking board and a cooking tool at several places in the circumferential direction. A technique of connecting and fixing to a board is disclosed, and the heat is made to be difficult by preventing the heat of the cooking board from being transmitted to the handle by the gap. In addition, the handle is the same height as the flange surface of the cooking board, but a protective wall that rises upward is formed on the inner peripheral side of the handle so that steam blown from between the cooking board and the lid does not face the handle side. It also provides thermal safety against blown steam.

  By the way, while the recent resource saving is screamed, the thickness of the accessory cooking utensils such as steaming vessels is becoming thinner. For this reason, with a one-handed handle as described in Patent Document 1, a handle is difficult to handle with a large steaming container, and the handle mounting part of the steaming container has a load during handling while gripping the handle. Concentration becomes a problem in durability. The thing of patent document 1 respond | corresponds by thickening the lip including the flange part of a steaming container, but such correspondence is contrary to resource saving and the steaming container becomes heavy, so it is inconvenient to handle. Become. In addition, there is a problem that the amount of overhang of the one-handed handle is large and it is easy to interfere with the surroundings.

  The one described in Patent Document 2 is a two-handed type with a pair of handles, so it is easy to handle, but the attachment to the steaming container is not different from the one-handed type handle of Patent Document 1, and the thin steaming container is used at the time of handling. Load concentration is a problem. In addition, there is no contrivance to regulate the steam blowing direction between the steaming container and the lid, and by making the handle lower than the opening of the steaming container, even if steam blows out to the side, it is difficult to achieve thermal safety. However, the amount of extension of the handle attached via the mounting bracket is relatively large, and it protrudes at the position where the outer periphery of the steaming container is interrupted, so there is a problem that it easily interferes with the surroundings.

  The handle described in Patent Document 3 has few members and does not have its own overhang, but is provided at two circumferential positions of an annular member that is in close contact with the outer periphery of the opening including the flange portion of the steaming vessel. Although it is close to the steaming vessel and is attached to the steaming vessel via a metal fitting, it is easy to be affected by heat from the steaming vessel and the temperature rises easily. There is a problem that the steam blown from between the container and the lid tends to reach.

  The handle described in Patent Document 4 is not easily affected by steam and heat from the cooking board, but requires a large number of connecting portions in the circumferential direction, and the volume of the cross section of the handle is large, which extends to the entire circumference. As a result, the entire volume of the handle is large, and it is expensive against resources.

  An object of the present invention is to provide a steamer capable of preventing steam from reaching the handle part without particularly complicating or increasing the volume of the handle member having a two-handed handle and the steaming container.

In order to solve the above-described problems, the steamer of the present invention includes a metal steaming container having a steam hole through which steam passes and a non-metallic handle having heat insulation, and the handle is steamed. A non-metallic ring-shaped handle member that is attached to the opening of the container and receives the lid is formed in a double-handed shape, and the handle member receives steam rising from the upper side of the peripheral wall of the steaming container from above. One feature is that a steam guide for guiding the lid toward the center of the steaming container from the receiving position of the lid is formed.

In such a configuration, the handle member is an annular form having a two-handed handle, and includes a handle for heat insulation to the outside of the opening of the metal steaming vessel, while satisfying including a handle. Regardless of the above, the lid is received by utilizing the annular shape, and the steam rising from the upper side of the peripheral wall among the steam from the bottom steam hole of the steaming container is received from above, and the steaming container is placed more than the receiving position of the lid. It is only necessary to form a steam guide that guides inward, and it is easy to prevent the steam from turning to the lid receiving position of the handle member by the steam guide by the steam guide and coming out to the outside, and is guided to the center side. Steam flows along the inside of the lid and wraps around the steaming area that reaches the center of the lid.

  In the above, the inner peripheral end of the steam guide may be further located inside the opening of the steaming container.

In such a configuration, in addition to the above, the steam guide extends further to the inside than the opening of the steaming vessel, so that the steam is guided to the center side, and the force flowing to the center side can be increased.

The steamer of the present invention also has a two-handed handle attached to the opening of the steaming vessel to receive a lid, and receives steam rising from the upper side of the peripheral wall of the steaming vessel from above. A steam guide for guiding toward the center of the steaming container is formed rather than the receiving position of the lid, and the width of the handle member in plan view is now larger on the handle side than on the side without the handle. One of is characterized.

In such a configuration, the handle member is an annular form having a two-handed handle, and regardless of the attachment form to the opening of the steaming container, the lid is received utilizing the annular form, and the peripheral wall of the steaming container It is sufficient to form a steam guide that receives steam rising from the upper side and guides the steam toward the inside of the steaming vessel from the receiving position of the lid, and the steam is guided by the steam guide to receive the lid of the handle member. It is easy to prevent it from turning to the outside and coming out to the outside, and the steam guided to the center side flows along the inside of the lid to wrap around the steaming area to the center part, and also entrains the surrounding steam It can be convected to enhance the work on the food. In particular, the strength of the handle side with a large handling load can be increased while suppressing the volume of the handle member. For this purpose, it is preferable that the width is increased to be elliptical or parabolic, with the outer circumference gradually distant from the circular inner circumference of the handle member.

According to one feature of the steamer of the present invention, the handle member is an annular form having a two-handed handle, and includes a handle for heat insulation around the opening of the metal steaming container, Regardless of the form of attachment to the opening, the lid can be received all around and only a vapor guide can be formed to guide the vapor rising from the inside of the peripheral wall out of the vapor at the bottom of the steaming vessel. The structure, steaming container, and lid are not particularly complicated or high in volume, and the steam guides the steam to the lid receiving position, or it goes out to the outside so that there is a person or hand. Because it makes it difficult to reach the side with the handle, it has thermal safety in use, and the flow that wraps around the steaming area guided to the center side also entrains the surrounding steam and convects it to the cooked food Steaming efficiency is improved by improving the work of Improvement, elimination of steamed non-uniformity can be achieved.

  In addition to the above, the steam guide extends further to the inside than the opening of the steaming vessel and guides the steam to the center side to increase the power flowing to the center side. Therefore, steam efficiency is further improved by steam convection and steaming. Unevenness can be eliminated.

According to another feature of the steamer of the present invention, the handle member is an annular shape having a two-handed handle, and the lid is received around the entire circumference regardless of the form of attachment to the opening of the steaming vessel. By simply forming a steam guide that guides the steam rising inside the peripheral wall of the entire circumference, the handle structure, steaming container, and lid are not particularly complicated or increase in volume, and the steam guide by the steam guide Since the steam moves to the lid receiving position or escapes to the outside, it becomes difficult to reach the side where there is a person or handle with hand, so it can be used for thermal safety and guided to the center side The steam that wraps around the steaming area entrains the surrounding steam and convects it to improve the effect on the cooked food, improving steaming efficiency and eliminating steaming. In particular , the width of the handle member in plan view, from the inner side of the handle toward the handle part, by increasing the outer diameter gradually from the inner circumference of the circle to an elliptical shape, parabolic shape, etc. Without complicating, it is possible to increase the strength of the handle side with a large handling load while suppressing the overall volume.

  One specific example of the steamer according to the embodiment of the present invention will be described with reference to FIGS. 1 to 8 for the understanding of the present invention. The following description is a specific example of the present invention and does not limit the description of the scope of claims. Other problems 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 in various combinations as much as possible.

  A steamer 100 according to the present embodiment shown in FIGS. 1 and 2 has an annular handle member 5 that has two-handed handles 1 and 2 and is attached to the opening 3 a of the steaming vessel 3 to receive the lid 4. A steam guide 8 is formed which receives steam 6 indicated by a solid line arrow rising from the upper side of the peripheral wall 3b of the steaming container 3 from above and guides the steam 6 toward the center of the steaming container 3 from the receiving position 7 of the lid 4. Yes. Thus, the handle member 5 of the present embodiment is an annular form as shown in FIG. 2 having the two-handed handles 1 and 2, regardless of the attachment form to the opening 3 a of the steaming container 3, A steam guide 8 that receives the lid 4 taking advantage of the annular form, receives the steam 6 rising from the upper side of the peripheral wall 3b of the steaming vessel 3 from above, and guides it from the receiving position 7 of the lid 4 toward the inside of the steaming vessel 3. It is easy to prevent the steam 6 from turning to the receiving position 7 of the lid 4 of the handle member 5 by the guidance of the steam 6 by the steam guide 8 and guided to the center side. The steam 6 flows in such a way as to wrap around the steaming region 11 extending to the center along the inside of the lid 4, and the surrounding steam is also involved and convected to enhance the action on the cooked food.

As a result, the handle member 5 is an annular form having the two-handed handles 1 and 2, and the lid 4 is received around the entire circumference of the steam container 3 regardless of the form of attachment to the opening 3 a of the steam container 3. Only by forming the steam guide 8 that guides the steam 6 rising inside the 3b around the entire circumference, the handle structure, the steaming vessel 3, and the lid 4 are not particularly complicated or increased in volume. As the steam 6 is guided to the receiving position 7 of the lid 4 by the guidance of the steam 6, it is difficult to reach the side where the person has a handle 1 or 2 held by hand. In addition to providing thermal safety in use, the flow of the steam 6 guided to the center side envelops the steaming region 11 also entrains the surrounding steam and causes convection as shown by the dashed arrows in FIG. Improve steaming efficiency and eliminate steaming unevenness It is.

  Here, the inner peripheral end of the steam guide 8 is assumed to be located inside the opening 3 a of the steaming container 3 as shown in FIGS. 1, 2, and 5. Thus, since the steam guide 8 extends to the inner side of the opening 3a of the steaming vessel 3, the steam 6 can be guided to the center side and the force flowing to the center side can be increased. Further improvement of steaming efficiency by convection and elimination of steaming unevenness can be achieved. Further, by this, the handle member 5 can receive the lid 4 by using the extension of the steam guide 8 to the inside of the opening 3a of the steaming container 3, and the steam guide 8 is shared by the mounting portion of the lid 4. The shape of the opening 3a of the steaming vessel 3 is not complicated, can be easily handled by setting the cross section of the handle member 5 by resin molding, and can easily take the form of the stepped portion 12 to which the lid 4 is fitted. . As a result, the receiving position 7 of the lid 4 is located farther from the handles 1 and 2 on the inner side than the opening 3a of the steaming vessel 3, and the thermal safety due to the leaked steam is enhanced. In addition, the stepped portion 12 can enhance the thermal safety due to the leaking steam by directing the leaking steam upward.

  The width of the handle member 5 in a plan view is such that the width B2 on the handle part 1, 2 side is larger than the width B1 on the side without the handle 1, 2 as seen in FIGS. It is said. Thus, the strength of the handles 1 and 2 with a large handling load can be increased while suppressing the volume of the handle member 25 inside the handles 1 and 2. For this purpose, the increase in width from B1 to B2 is preferably an elliptical or parabolic shape whose outer periphery is gradually far from the circular inner periphery of the handle member 5 shown in FIGS. In addition, the strength of the handles 1 and 2 with a large handling load can be increased while suppressing the overall volume without complicating the shape, and the appearance is not impaired. Separately or in combination with this, the handle member 5 can be increased in strength against the handling load on the handles 1 and 2 side by increasing the wall thickness in accordance with the increase from the width B1 to the width B2. These strength increases also increase the mounting strength of the steaming container 3 on the opening 3a on the handle 1, 2 side where the handling load is large. In FIG. 3, the outer periphery of the handle member 5 is switched at the switching position 19.

  Moreover, as shown in FIGS. 1, 2, 5, and 6, the top surfaces 1a and 2a of the handles 1 and 2 are made lower than the top surface 5a of the handle member 5. Even when cooking is used in a steam-closure state, even if the lid 4 is lifted somewhat and the steam 6 leaks sideways between the handle member 5 and the lid 4, it will reach the handles 1 and 2. Since this can be prevented, the thermal safety of the handles 1 and 2 can be achieved.

  As shown in FIGS. 1 and 2, a steam vent 23 is provided at the center of the lid 4 so that the steam hole 22 can be opened and closed by rotating the shutter 21 with the lever 21a. While enabling the advantageous use for repeated convection of the fully closed steam 6, when the steam vent 23 is opened, it reaches the center position of the steam 6 guided toward the center by the steam guide 8 according to the opening degree. In order to create a stronger flow, increase the circulation to the cooked food, and activate the convection flow and convection of the steam 6 from the peripheral wall 3b side of the steaming vessel 3 to the central position according to the degree of closing of the steam vent 23. I can plan. As a result, the steam vent 23 is directed to the center side by the steam guide 8 according to the opening degree at the center of the lid 4 while enabling advantageous use for repeated convection of the steam 6 with the steam vent 23 fully closed. The longer and stronger flow to the center position of the steam 6 to be guided increases the direction to the cooked food, and the steam 6 extends from the peripheral wall 3b side of the steaming vessel 3 to the center position according to the degree of closing of the steam vent 23. By increasing the flow rate and convection, steaming efficiency can be further improved and steaming unevenness can be eliminated.

  More specifically, the handle member 5 includes an upper handle member 51 made of synthetic resin as shown in FIG. 3 and a lower handle member 52 made of synthetic resin shown in FIG. 4 and an upper handle member 51 shown in FIG. As shown in FIGS. 1 and 5, the engaging claws 51b formed integrally with the left and right handle pieces 51e of the outer peripheral wall 51a are forcibly fitted to the outer peripheral notch edge 52b1 of the handle piece 52b of the lower handle member 52. The upper and lower fitting members 51 are fitted to the upper part 3a of the upper handle member 51 by fitting the upper and lower parts and sandwiching the periphery of the opening part 3a including the outward flange 3c of the steamer container 3. The handle pieces 51e and 51e of the lower handle member 52 and the handle pieces 52b and 52b of the lower handle member 52 are sandwiched by screws 61 screwed from below the handle piece 52b as shown in FIG. It can be securely held by fastening in the direction. , It can also detent between the upper handle member 51 and the lower handle member 52. Further, the upper handle member 51 has a main form including the handles 1 and 2 of the handle member 5 and the steam guide 8, and the lower handle member 52 is formed between the outer peripheral wall 51a and the inner peripheral wall 51d as an auxiliary member for clamping. It is accommodated in the downward concave portion 51c so as not to be covered. At the same time, the upper handle member 51 has a deep recess 51c1 that accepts the opening 3a including the outward flange 3c of the steaming vessel 3 of the recess 51c higher than the top surfaces 1a and 2a of the handles 1 and 2 from below. A gap having a bowl-shaped cross section (Γ-type) is formed between the base 52 and the base peripheral wall 52a of the member 52, and the upper part of the bowl-shaped (Γ-type) peripheral wall 3b of the steaming vessel 3 and the flange 3c are sandwiched. Further, a seal packing 31 is sandwiched between the flange 3c and the upper handle member 51 as shown in FIG.

  Further, the outer peripheral wall 51d excluding the handle piece 51e of the upper handle member 51 and the thickness of the base peripheral wall 52a of the lower handle member 51 are increased from the side without the handles 1 and 2 to the side of the handles 1 and 2, It is thicker than that of the upper handle member 51 on the first and second sides. Further, the steaming container 3 and the upper handle member 51 are expanded to provide a screw hole 62 for fastening by the screw 61 on the inner peripheral surface of the outer peripheral wall 51a of the upper handle member 51 where the handle piece 51e is not provided. The rotation is prevented by the engagement between the formed rib 51f and the notch 3d shown in FIG. 8 formed on the outer periphery of the flange 3c of the steaming vessel 3. Correspondingly, the lower handle member 52 has an undercut portion 63 that escapes from the rib 51f on the outer periphery, a peripheral wall 64a from the inner peripheral surface to the handle piece 52b side, and is formed in an undercut shape from the lower surface side. The attached mounting surface 64 extends in a groove shape on the back side of the handle piece 52b, and the mounting surface 65 is formed so as to penetrate the mounting hole 65 corresponding to the screw hole 62 up to the upper surface of the handle piece 52b. The screw 61 is screwed into the screw hole 62 through the hole 65.

  As shown in FIG. 8, steam holes 3e, 3f, 3g, and 3j having different sizes are provided at the bottom of the steaming vessel 3, particularly the central region 3k that is the lowest level, and the amount of steam as a whole and While adjusting the street distribution, the small steam holes 3f and 3g restrict the water suction and suction. The large steam holes 3e are limited to the number of four locations around the bottom and the number of them is limited so that they can easily flow out even if there is intrusion water or dew condensation water. The steam holes 3f are arranged almost evenly over the entire bottom so as to secure the passage of steam while restricting the suction of water, and the diameter is effective, for example, as 3 to 5 mm, which is halved than usual. The small steam hole 3g is provided in the reinforcing installation part 3h having a rib shape or the like protruding downward at the bottom part, and has a diameter that is more difficult for water to pass because it is closest to the water surface side. Yes. The steam hole 3j is arranged on the outermost periphery of the central region 3k so that the condensed water that is condensed and transferred mainly on the inner surface of the peripheral wall of the steaming vessel 3 can easily flow down to the bottom before reaching the steaming region 11. . For this purpose, the steam hole 3j is preferably at least as large as the steam hole 3f. However, in order to prevent a large amount of steam from bypassing the outer periphery of the steam region 11, Since it becomes a problem to make it as large as 3e, it is preferable to set the upper limit of the large diameter dimension of the steam hole 3f.

  The present invention complicates a handle member having a two-handed handle and a steaming container in the steamer, and can prevent the steam from reaching the handle portion without increasing the volume.
