Description

  The present invention relates to a cover for heating a content, for example, a cover for enhancing a heat retaining effect by attaching to a pot. It relates to a cover for attaching to a pan such as a small pan. It also relates to the container itself for heating the contents.

  With reference to FIG. 14, the usage form of the conventional small-sized pan is demonstrated. Conventionally, when it is desired to heat some contents using the size pan 1, the size pan 1 containing the content is placed on the stove 3 as it is and heated from below by the flame 2 that the stove 3 emits. However, when the size pan 1 is large, it takes time until the contents are sufficiently heated. Therefore, while heating from below, the heat escapes from the outer peripheral surface of the short pan 1 and the like, which is inefficient.

In order to solve this problem, what is called an energy saving warm cover is proposed as disclosed in Utility Model Registration No. 3087029 (Patent Document 1).
Utility model registration No. 3087029

  The energy-saving heat insulation cover shown by the said patent document 1 is aiming at the fixed effect which raises the heat insulation efficiency of a hollow pot by forming the hollow cylindrical space covered with the cylindrical member in the outer periphery of a hollow pot. I can hear. However, this energy-saving insulation cover is provided with a bottom ring at the lower end, so that the hollow cylindrical space inside is completely closed, so even if this energy-saving insulation cover is attached, it is heated with strong heat. In this case, it is considered that the flame 2 protrudes further outside the energy-saving heat retaining cover 100 as shown in FIG. Therefore, a part of the heat of the flame 2 escaped into the air, and the heat energy originally generated by the flame 2 was not sufficiently absorbed by the short-bottle pan 1.

  Therefore, in the present invention, when heating the contents using a container such as a small-sized pan, the purpose is to prevent waste of energy associated with the flame protruding outside the container and to make effective use of the energy. To do.

  In order to achieve the above object, a cover according to the present invention is a cover that can be attached to a container for heating the contents so as to cover the outer peripheral surface of the container, and is separated from the outer peripheral surface by a certain distance. An outer shell for surrounding the outer peripheral surface is provided, and an open portion is provided between the lower end of the outer shell and the container. By adopting this configuration, the flame that protrudes outside the container can be taken into the outer shell from the open part, so that the heat energy of the flame is hardly released to the outside and is directed to heating the contents of the container with high efficiency. be able to. Moreover, since the flame which tries to protrude from the container can be enclosed inside the outer shell, the temperature rise of the surrounding environment can also be prevented.

  Preferably, in the above invention, the outer shell is divided into two parts, and the attachment to the container is performed such that the container is sandwiched between the two parts. By adopting this configuration, it is not necessary to move or lift the container, and the installation and removal operations can be simplified.

  Preferably in the above invention, a pipe disposed along the outer peripheral surface of the container inside the outer shell, a liquid inlet for supplying liquid to the pipe, and a liquid for taking out the liquid from the pipe A liquid outlet. By adopting this configuration, by flowing the liquid into the pipe from the liquid inlet to the liquid outlet, the liquid can be taken out in a high temperature state by effectively using the thermal energy of the flame taken into the outer shell from the open portion. .

  Preferably, in the above invention, the outer shell is divided into two parts, and each of the two parts is provided with a pipe disposed separately along the outer peripheral surface of the container on the inner side. The attachment is performed such that the container is sandwiched between the two parts, and includes a liquid inlet for supplying liquid to the tube and a liquid outlet for taking out the liquid from the tube, The tube is arranged to meander along the outer peripheral surface inside each of the two portions. By adopting this configuration, it is possible to simplify the installation and removal work, and the liquid is allowed to flow into the pipe from the liquid inlet to the liquid outlet in each of the two parts, and is taken into the outer shell from the open portion. The liquid can be taken out at a high temperature by effectively using the heat energy of the flame. In particular, since the tube is arranged to meander within each of the two parts, the liquid circulating inside the tube can be exposed to a flame for a long distance in the circulation, and the temperature can be sufficiently raised. it can.

  Preferably, in the above invention, an upper cover plate that closes a gap between the outer peripheral surface and the outer shell is provided at an upper end of the outer shell. By adopting this configuration, hot air or flame can be prevented from being ejected from the upper end, which is safe for the operator.

  In the above invention, preferably, the pipe is a copper pipe. By adopting this configuration, it is possible to obtain a tube that is inexpensive, easy to process, and excellent in thermal conductivity.

  In order to achieve the above object, a container according to the present invention includes any one of the above-described covers as a cover portion. By adopting this configuration, the flame that protrudes outside can be taken into the inside of the cover part, so that it becomes a container that can direct the heating of the contents with high efficiency without escaping the thermal energy of the flame almost to the outside. . Further, since the flame can be contained inside the cover portion, the temperature rise in the surrounding environment can be prevented.

  Preferably, in the above invention, the cover portion is configured integrally with the container body. By adopting this configuration, the trouble of attaching the cover to the container body can be saved. Further, there is no fear that the cover will be undesirably removed or displaced during use, and the worker can concentrate on the work with peace of mind.

  According to the present invention, since the flame that protrudes outside the container can be taken into the outer shell, the contents of the container can be efficiently used by effectively utilizing the heat energy of the flame that has been conventionally discharged into the air and wasted. Can be heated. Moreover, since the flame which is going to protrude from the container can be enclosed inside the outer shell, the temperature rise of the surrounding environment can be prevented, which contributes to the improvement of the worker's environment. In addition, the risk of ignition to the surrounding area due to the protruding flame can be reduced.

(Embodiment 1)
(Constitution)
With reference to FIGS. 1-3, the cover 110 in Embodiment 1 based on this invention is demonstrated. FIG. 1 shows a perspective view of the cover 110 alone. This cover 110 is a cover that can be attached to a container for heating the contents so as to cover the outer peripheral surface of the container. The container for heating the contents is a pan or the like, but here, as an example, a short-sized pan is assumed, and a cover that can be attached to the short-sized pan is provided.

  The cover 110 includes an outer shell 15 as shown in FIG. The outer shell 15 is used to surround the outer peripheral surface of the short pan by being spaced apart from the outer peripheral surface of the short pan by a certain distance when attached to the short pan. The cover 110 is divided into two parts, that is, a right side part 40a and a left side part 40b symmetrically by dividing the outer shell 15 into two parts. These two parts are connected to each other by a hinge (not shown) at one end. The right side portion 40a and the left side portion 40b are provided with upper cover plates 8a and 8b on the upper side, respectively. As shown in FIG. 1, at the lower end of the cover 110, unlike the upper end, there is no plate serving as a bottom surface, and the inside of the outer shell 15 is open, which are open portions 9a and 9b.

(Example of use)
With reference to FIG. 2, the usage example of the cover 110 in this Embodiment is demonstrated. The cover 110 is attached to the girdle pan 1 so as to cover the outer peripheral surface 19 thereof. That is, the cover 110 wraps around the outer peripheral surface 19 of the inked pan 1 so as to be sandwiched between the right side portion 40a and the left side portion 40b. The tips of the right side 40a and the left side 40b are not fixed in FIG. 2 but are actually fixed to each other by a known technique. For example, the method may be a method in which the through holes are overlapped to penetrate the rod, a method of locking with a hook, or a method of attracting with a magnet. In short, what is necessary is just to be able to fix in the state which pinched | interposed the pancake 1 between the right side part 40a and the left side part 40b.

(Action / Effect)
FIG. 3 shows a partial cross-sectional view in the vicinity of the cover 110 when in use. The contents 17 are contained in the inner pot 1. In order to heat the contents 17, the flame 2 is applied to the bottom surface of the full-size pan 1. The flame 2 does not fit only on the bottom surface of the screen pan 1 and protrudes outside the screen pan 1.

  However, since the cover 110 is attached to the outside of the size drum pan 1, and the cover 110 has the open portion 9a, the flame 2 that protrudes outward from the bottom surface of the size drum pan 1 enters the gap 18 from the open portion 9a.

  In this way, the hot pot 1 is heated from the outer peripheral surface 19 in a state where the front end of the flame 2 is confined in the gap 18 which is a space surrounded by the outer shell 15. In the present embodiment, since the outer side of the flame 2 is surrounded by the outer shell 15, heating of the outer peripheral surface 19 or the inside of the gap 18 is performed without releasing most of the heat energy that has been released to the outside. Can be directed to the heating of air. The air in the gap 18 that has reached a high temperature contributes to the heating of the girdle pan 1. Therefore, as a whole, in the present embodiment, the heat energy of the flame 2 can be directed to the heating of the contents 17 of the full-size pan 1 with high efficiency without escaping to the outside. In addition, in the prior art, the main body 1 was heated mainly from the lower surface, whereas in the present embodiment, the flame 2 extends upward along the gap 18 and the outer shell 15 is formed. Since the heated air is held in the entire range, the inner pan 1 is heated not only from the lower surface of the pan 1 but also from a relatively high position on the outer peripheral surface 19. Thus, the contents 17 at a high position can be quickly heated.

  In the present embodiment, since the flame 2 that has conventionally protruded to the outside enters the gap 18 and is covered with the outer shell 15, it is possible to prevent the temperature of the surrounding environment from rising. Therefore, it is possible to provide a more comfortable environment to surrounding workers who have been forced to work at high temperatures. In addition, since the flame 2 is confined in the outer shell 15, the risk that the protruding flame 2 may ignite other surrounding objects can be reduced.

  In FIG. 3, the upper cover plate 8 a is in intimate contact with the outer peripheral surface 19 of the screen pan 1. The close contact is preferable because the effect of maintaining the high-temperature air in the gap 18 is enhanced, but a certain effect can be obtained even if the close contact is not necessarily achieved. If necessary for ventilation, the upper cover plate 8a or the outer shell 15 may be appropriately provided with a through hole.

(Embodiment 2)
(Constitution)
With reference to FIGS. 4-7, the cover 120 in Embodiment 2 based on this invention is demonstrated. FIG. 4 shows a perspective view of the cover 120 alone. This cover 120 is a cover that can be attached to the short-span pan, similarly to the cover 110 in the first embodiment.

  The cover 120 includes an outer shell 15 as shown in FIG. The outer shell 15 is the same as that described in the first embodiment. The cover 120 is divided into two parts, that is, a right side part 40a and a left side part 40b symmetrically by dividing the outer shell 15 into two parts. These two parts are connected to each other by a hinge (not shown) at one end. In FIG. 4, for convenience of explanation, a part of the outer shell 15 is notched in the right side portion 40a.

  The right side portion 40a and the left side portion 40b are provided with upper cover plates 8a and 8b on the upper side, respectively. Liquid inlets 6a and 6b and liquid outlets 7a and 7b are disposed on the upper cover plates 8a and 8b, respectively. Tubes 5 a and 5 b are arranged inside the outer shell 15. The tube 5a is accommodated in the right side portion 40a, and the tube 5b is accommodated in the left side portion 40b. The upper sides of the tubes 5a and 5b are covered with upper cover plates 8a and 8b, respectively. The tubes 5a and 5b are covered with the outer shell 15 when viewed from the outside, but are exposed to the inside.

  Inside the right side 40a of the cover 120, the pipe 5a connects the liquid inlet 6a and the liquid outlet 7a. An arrangement example of the pipe 5a is shown in FIG. In FIG. 5, the right side portion 40a, which is originally curved in a semi-cylindrical shape, is expanded into a flat state for convenience of explanation, and the arrangement of the tubes 5a is shown. In FIG. 5, the pipe 5a meanders along the outer peripheral surface of the short pan, but the shape of the pipe 5a is merely an example, and is a path from the liquid inlet 6a to the liquid outlet 7a inside the right side 40a. If it exists, another route may be used.

  Similarly, the pipe 5b is disposed in the left side 40b of the cover 120, and connects the liquid inlet 6b and the liquid outlet 7b.

  As shown in FIG. 4, at the lower end of the cover 120, unlike the upper end, there is no plate-like portion constituting the bottom surface, which is open, and these are open portions 9a and 9b.

(Example of use)
With reference to FIG. 6, the usage example of the cover 120 in this Embodiment is demonstrated. The cover 120 is attached to the girdle pan 1 so as to cover the outer peripheral surface 19 thereof. This attachment method is the same as that described in the first embodiment.

  Further, an inlet-side outer pipe 10 is connected to the liquid inlets 6a and 6b. The other end of the inlet-side outer pipe 10 is connected to a water supply or the like. An outlet side outer pipe 11 is connected to the liquid outlets 7a and 7b. A faucet 12 is connected to the outlet-side outer pipe 11. In FIG. 6, only one faucet 12 is displayed, but a plurality of faucets may be arranged.

(Action / Effect)
As described above, the cover 120 is attached to the size pan 1 and the inlet-side outer pipe 10 is provided, so that new water is supplied into the cover 120 from the liquid inlets 6 a and 6 b through the inlet-side outer pipe 10.

  FIG. 7 shows a partial cross-sectional view in the vicinity of the cover 120 in use. The contents 17 are contained in the inner pot 1. In order to heat the contents 17, the flame 2 is applied to the bottom surface of the full-size pan 1. The flame 2 does not fit only on the bottom surface of the screen pan 1 and protrudes outside the screen pan 1.

  However, since the cover 120 is attached to the outside of the size drum pan 1 and the cover 120 has the open portion 9a, the flame 2 that protrudes outward from the bottom surface of the size drum pan 1 enters the gap 18 from the open portion 9a. Thus, the same effect as described in the first embodiment can be obtained first.

  Furthermore, there is a tube 5a in the gap 18, and the flame 2 that has entered the gap 18 heats the tube 5a. Since water supplied from the liquid inlets 6a and 6b passes through the pipe 5a, the water is heated to become hot water. The hot water can be taken out by opening the tap 12 shown in FIG. The extracted hot water may be freely used for various purposes.

  Since the pipe 5a meanders along the outer peripheral surface 19 of the short pan 1 in the gap 18, even in a state where water is continuously circulated in the pipe 5a with the faucet 12 kept open. If 2 is sufficiently strong, the water is sufficiently heated while passing through the pipe 5a. As a result, hot water can be continuously taken out from the tap 12. The hot water taken out in this way is obtained by effectively using the heat energy that was previously wasted by the flame 2 protruding to the outside, and does not require additional input of new energy. It is obtained. Here, the state in the right side portion 40a is described, but the same operation and effect can be obtained in the left side portion 40b. The water heated by the pipe 5 a and the water heated by the pipe 5 b merge at the outlet-side external pipe 11 and are supplied toward the faucet 12.

  If this cover 120 is used, in addition to the effects described in the first embodiment, there is a merit that water can be changed to hot water by using the extra thermal energy of the flame 2.

  The cover may have a structure in which the inner shell 16 is provided in addition to the outer shell 15 as in the cover 121 shown in FIG. Like the outer shell 15, the inner shell 16 is configured to be separable left and right. In this case, the tubes 5a and 5b are covered with the inner shell 16 and cannot be seen even when viewed from the inside in a state of being removed from the size pan 1. In the cover 121, a space sandwiched between the outer shell 15 and the inner shell 16 becomes a gap 18 as shown in FIG. When the cover 121 is used, the flame 2 that has entered the gap 18 passes through the inner shell 16 when heating the outer peripheral surface 19 of the girdle pan 1, so in terms of supplying heat energy to the girdle pan 1. Although the efficiency is slightly worse, the presence of the inner shell 16 has the advantage that the strength of the entire cover can be improved and that the pipes 5a and 5b can be prevented from being damaged due to inadvertent contact accidents.

  The tubes 5a and 5b are preferably copper tubes. This is because the material is inexpensive, easy to process, and excellent in thermal conductivity.

  In the present embodiment, an example is shown in which the liquid flowing inside the tubes 5a and 5b is water, but the liquid may be other than water. For example, it may be soup.

  In the present embodiment, as shown in FIG. 6, the bifurcated inlet side outer pipe 10 is used to supply liquid in parallel to both the right side 40a and the left side 40b, and the right side 40a. In this example, the liquids that have passed through the liquid outlets 7a and 7b through the interiors of the left and right side portions 40b and merged in the outlet-side outer pipe 11 are joined. The way is not limited to such parallel ones. For example, they may be connected in series. In that case, when any one of the right side portion 40a and the left side portion 40b is referred to as a first side and the other side is referred to as a second side, the inlet side external pipe 10 is connected to the liquid inlet on the first side. The liquid is supplied only to the second side, the liquid passing through the first side and exiting from the liquid outlet is guided to the second side liquid inlet to pass through the second side, and the second side The liquid exiting from the liquid outlet is guided to the faucet 12 and the like by the exit-side outer pipe. In this way, the length of the path through which the liquid flows while being heated is increased, and the liquid can be heated more reliably.

  In either case of serial connection or parallel connection, the positions of the liquid inlet and the liquid outlet of the right side 40a and the left side 40b may be appropriately set according to the convenience. For example, when connecting in series, If it arrange | positions so that the inlet_port | entrance of 2 side may mutually become close, since the length of the pipe | tube required for the connection between both can be shortened, it is preferable.

  In the first and second embodiments, the upper cover plates 8a and 8b are provided. In this case, since the upper end of the gap 18 is closed by the upper cover plates 8a and 8b, air heated inside the outer shell 16 can be confined in the gap 18, which is preferable. However, even if the upper cover plates 8a and 8b are not provided and the upper end is open like the lower end, the flame that tries to protrude outside is taken into the outer shell, and the contents of the container are placed on the outer peripheral surface of the container. Therefore, a certain degree of effect can be obtained. Compared to this, if the upper cover plates 8a and 8b are provided, hot air or flame can be prevented from being ejected from the upper end, which is safer and more preferable for the operator.

  In both of the first and second embodiments, the cover structure is divided into two parts on the right and left sides, and these are connected to each other via a hinge. However, as a cover based on the present invention, It is not restricted to such a form. There may be no left and right separated state when there is no hinge and it is removed. Moreover, it may consist of three or more parts instead of two on the left and right. Moreover, it is an integral cylindrical thing, Comprising: It may be the form which fits in from a top or the bottom with respect to a size drum pan.

(Embodiment 3)
(Constitution)
With reference to FIG. 10, description will be given of an inked pan 1 i as an example of a container according to Embodiment 3 of the present invention. The size pan 1i includes a cover part 130 as a part thereof. The cover part 130 is covered so that the outer side of the pan main body outer peripheral surface 19n may be surrounded. Although the cover part 130 may be comprised so that attachment or detachment is possible as a separate component with respect to the main body of the full-size pan 1i, it may be connected with respect to the main body of the full-size pan 1i, and may be integral. In this embodiment, it is assumed that it is an integrated object.

(Example of use)
FIG. 11 shows a partial cross-sectional view of the size pan 1i in use.

(Action / Effect)
Also in this embodiment, the same effect as the effect in Embodiment 1 can be obtained. Furthermore, if the cover part 130 is formed integrally with the main body part of the pancake pan, the trouble of attaching the cover to the pancake pan can be saved. Further, there is no fear that the cover will be undesirably removed or displaced during use, and the worker can concentrate on the work with peace of mind.

(Embodiment 4)
(Constitution)
With reference to FIG. 12 and FIG. 13, description will be given of a small-sized pan 1 j as an example of a container according to Embodiment 4 of the present invention. FIG. 12 is a perspective view of the small-size pan 1j as seen from diagonally below. FIG. 13 is a partial cross-sectional view of the size pan 1j. The small pan 1j is provided with a cover 131 that covers the outside of the pan body outer peripheral surface 19n. The cover part 131 is formed integrally with the main body part of the full-size pan 1j. A gap 18 is formed between the cover portion 131 and the pan body outer peripheral surface 19n. A lower cover plate 9 f is provided at the lower end of the cover portion 131 so as to cover the gap 18. However, the lower cover plate 9f is provided with a flame intake hole 9h as an open portion, and the flame can enter the gap 18 from the flame intake hole 9h when used.

(Action / Effect)
In the present embodiment, there is a possibility that the flame that has not entered the flame intake hole 9h may escape to the outside of the cover portion 131, and in terms of the utilization efficiency of heat energy, it is different from the other embodiments. Although it is slightly inferior to that of the prior art, it is still possible to sufficiently increase the utilization efficiency compared to the prior art and to obtain substantially the same effect as that of the third embodiment. Furthermore, in the case where the cover portion 130 is formed integrally with the main body portion of the case-like pan as in the case-pan 1i (see FIG. 11) in the third embodiment, the cover portion 130 cannot be removed and washed, In addition, since the lower side of the cover part 130 is widely opened as the open parts 9a and 9b, the dirt inside the cover part 130 can be seen well, but the size of the pan 1j according to the fourth embodiment (see FIGS. 12 and 13). If the cover portion 131 is provided as described above, the presence of the lower cover plate 9f makes it difficult to see dirt inside the cover portion 131, and the aesthetic appearance can be maintained. In addition, when the heating by the flame from below is stopped, in this embodiment, the air flow path between the inside and outside of the cover part 131 is limited to the flame intake hole 9h, so the high temperature air inside the cover part 131 is It becomes difficult to escape to the outside and stays inside the cover part 131 for a longer period of time, so that the contents of the short-size pan 1j are difficult to cool.

  In the containers of the third and fourth embodiments, the concept of the second embodiment may be applied to provide a structure in which a pipe can be provided inside the cover unit 130 or the cover unit 131 to allow liquid to flow.

  In addition, in the cover of Embodiment 1, 2, it is good also as providing the lower side cover board which has a flame intake hole like Embodiment 4. FIG. In this way, high-temperature air remains inside the cover even after the supply of flame is stopped, and the heat retention can be improved.

  In each of the above embodiments, an example in which the container to be heated is a full-size pan is shown, but a pan other than the full-size pan may be used. Further, the container is not limited to cooking utensils such as pots, and may be containers of other fields as long as the contents are heated.

  In addition, the said embodiment disclosed this time is an illustration in all the points, Comprising: It is not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and includes all modifications within the scope and meaning equivalent to the terms of the claims.
