Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of instant food, in particular to a heating device-grade instant food bowl. Background Art
[0002] Existing self-heating instant foods usually use self-heating bags immersed in room temperature water to generate steam for heating, which is mainly used to steam solid instant foods such as rice and vegetables, and cannot effectively heat foods containing a lot of liquid water such as soups and porridge in a short time. In addition, existing self-heating bags cannot be directly added with hot water, because the self-heating bags react quickly when they come into contact with water, which can easily cause hot water to splash and scald people. Therefore, only room temperature water can be added, which limits its use.
[0003] Existing instant foods are generally brewed with boiling water or hot water, which has the following problems: (i) In a cold environment, the heat of hot water dissipates quickly and cannot reach the temperature to fully brew the food, and cannot restore the taste of the food well; (ii) For ingredients such as rice noodles that require a long time and high temperature to undergo gelatinization, the energy of hot water alone is not enough to heat and restore the ingredients. Therefore, a heating device that can heat food is needed. Utility Model Content

DETAILED DESCRIPTION
[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.
[0030] Embodiment 1
[0031] like Figure 1 As shown, a heating device 16 provided in this embodiment includes a first shell 1, a second shell 2, a water vapor channel 3, a self-heating bag 4, a first partition 5, a second partition 6, a first through hole 7, a second through hole 8, a third through hole 9, a fourth through hole 10, a water storage tank 11, a self-heating tank 12, a water-soluble film 13 and a gelling powder bag 14.
[0032] The first shell 1 has a length direction X and a width direction Y, and can be designed as a cylindrical, closed structure. A third through hole 9 is arranged on the upper side wall, and the third through hole 9 is 2-3 mm higher than the top of the second shell 2. A fourth through hole 10 is arranged at each end of the length direction X of the lower side wall.
[0033] The second shell 2 is cylindrical and is placed inside the first shell 1, and shares a bottom plate with the first shell 1. There is a gap between the first shell 1 and the second shell 2 on both sides of the length direction X, and the gap forms a water vapor channel. The interior of the second shell 2 is provided with a self-heating bag 4, a first partition 5 and a second partition 6 from bottom to top. The second partition 6 is the top plate of the second shell 2.
[0034] The first partition plate 5 is provided with a first through hole 7 , and the first through hole 7 is covered with a water-soluble film 13 . The water-soluble film 13 is a starch film. The thicker the film is, the slower the film is dissolved, so as to reduce the contact time between water and the natural bag 4 .
[0035] The second partition 6 is provided with a second through hole 8, a self-heating chamber 12 is formed between the first partition 5 and the self-heating bag 4, and a water storage chamber 11 is formed between the first partition 5 and the second partition 6. The fourth through hole 10, the water vapor channel 3, the second through hole 8, the water storage chamber 11, the first through hole 7 and the self-heating chamber 12 are connected. The second through hole 8 and the first through hole 7 are aligned up and down. The third through hole 9 is provided with a gelling powder bag 14 that can solidify rainwater. The content of the gelling powder bag 14 can be carrageenan, sodium alginate or ice powder used to make jelly snacks.
[0036] In this embodiment, the second partition plate 6 is a structure with a downward depression in the middle, and the second through hole 8 is disposed in the middle of the second partition plate 6 .
[0037] like Figure 2 As shown, the utility model also provides a convenient food bowl, including a container 15 and the above-mentioned heating device 16, wherein the heating device 16 is placed in the middle of the container 15, and the bottom of the heating device 16 can be detachably bonded to the bottom of the container 15.
[0038] When in use, food is placed in the container 15. Hot water is injected into the container 15 and the hot water reaches the water filling scale line on the inner wall of the container 15. The upper edge of the third through hole of the heating device is also marked with a water filling line. During the water filling process, hot water enters the water vapor channel 3 from the fourth through hole 10. At this time, the air in the heating device 16 is discharged from the third through hole 9 (the gelling powder package 14 is breathable in a dry state). When the water level in the container 15 reaches the water filling scale line, the water in the heating device 16 is submerged above the second partition 6 and the third through hole 9 at the same time, and then enters the water storage tank 11 from the second partition 6 through the second partition 6. The gelling powder package 14 on the third through hole 9 becomes a colloid when it meets water, blocking the third through hole 9, so that the gas in the heating device 16 is no longer discharged from the third through hole 9, and the water no longer enters the water vapor channel 3 from the fourth through hole 10.
[0039] The water in the water storage tank 11 contacts the water-soluble film 13, causing the water-soluble film 13 to slowly dissolve. At the beginning, due to the thicker thickness of the water-soluble film 13, the speed at which the water-soluble film 13 is dissolved is slower, thereby controlling the opening time of the first through hole 7 to control the time when the self-heating bag 4 starts heating, which is usually designed to be dissolved in 15 to 20 seconds.
[0040] Put a lid on the container 15. The water in the water storage tank 11 passes through the water-soluble membrane 13 and enters the self-heating tank 12 to contact the self-heating bag 4. The self-heating bag 4 undergoes an exothermic reaction to produce a large amount of high-temperature steam. As the steam pressure in the device rises, the high-temperature steam passes through the first through hole 7 and the second through hole 8 in sequence upward into the water vapor channel 3, and is discharged from the fourth through hole 10 to the container 15 together with the water remaining in the water vapor channel 3 to contact the food for heat exchange to achieve heating. At the same time, the heat of the high-temperature steam and the self-heating bag passes through the side wall of the second shell 2 and the side wall of the first shell 1, and is transferred to the food in the container 15 to achieve heating. When eating, the heating device 16 can be pulled out.
[0041] Embodiment 2
[0042] like Figure 3 As shown, the first embodiment is repeated, except that, in this embodiment, the second partition plate 6 is inclined to one side, the second through hole 8 is disposed on the inclined end of the second partition plate 6, the first shell 1 and the second shell 2 share a bottom plate and a side wall (one side in the width direction Y), and the shared side wall is in contact with the inner wall of the container 15 (as shown in FIG. Figure 4 As shown in FIG. 1 ), the water vapor channel 3 is formed on the other side of the second shell 2 in the width direction Y. The fourth through hole 10 is provided with one.
[0043] Embodiment 3
[0044] The second embodiment is repeated, except that, in addition to the water vapor channel 3 being provided on one side of the width direction Y of the first shell 1 and the second shell 2, both are also provided with water vapor channels 3 on both sides of the length direction X, and three fourth through holes 10 corresponding to the water vapor channels 3 are provided on the side wall of the first shell 1.
[0045] The heating device of the utility model controls the water volume by its internal air pressure, and the self-heating chamber is reserved with a safety space, so even if the water is overfilled accidentally, there will be no danger of hot water overflow. The double-layer partition can effectively prevent the solution after the reaction in the self-heating chamber from flowing back.
[0046] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
