[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0046] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0047] At present, there are many beverage processing equipment such as kettles, coffee machines and milk tea machines on the market that have heating function and instant heating function, which can instantly heat beverages; generally, beverage processing equipment with instant heating function basically includes an inner tank, a heating wire and an instant heating pipe, the heating wire is attached to the instant heating pipe, and the instant heating pipe connects the inner tank with the water outlet pipeline of the beverage processing equipment; when the user uses the instant heating function of the beverage processing equipment, the heating pipe is powered on and heated, and then the heat is transferred to the instant heating pipe, and the liquid in the instant heating pipe absorbs heat to complete the heating process of the beverage.

[0048] In order to reduce the volume of beverage processing equipment while retaining the heating function and instant heating function, the heating wire is generally set on the instant heating pipe, the instant heating pipe is connected to the inner tank and the water outlet pipe, and the instant heating pipe and the heating wire are both attached to the bottom of the inner tank of the beverage processing equipment, thereby reducing the overall volume of the beverage processing equipment. However, the above arrangement method will cause most of the heat generated by the heating wire to be transferred to the inner tank, resulting in insufficient heat transferred to the instant heating pipe, thereby reducing the upper limit of the water outlet temperature of the instant heating pipe.

[0049] Reference Figures 1 to 3 In order to solve the above problems, the utility model proposes a liquid heating container, including a water pipe 100 and a heating pipe 200. The water pipe 100 is connected with the inner tank of the beverage processing equipment, so that the water in the inner tank can flow out through the water pipe 100; correspondingly, the heating pipe 200 is used to heat the water pipe 100, so that the water can absorb the heat generated by the heating pipe 200 when flowing through the water pipe 100, so that the heat generated by the heating pipe 200 will increase the temperature of the water in the water pipe 100, and then the temperature of the water after flowing out of the water pipe 100 is higher than the temperature before entering the water pipe 100, thereby completing the instant heating of the water.

[0050] Reference Figures 2 to 4 In order to improve the instant heating efficiency of the overall structure for water, that is, to enable the water to obtain more heat in the process of flowing through the water pipe 100, in one embodiment of the present invention, the water pipe 100 is spirally arranged, so that the water flow time in the water pipe 100 is prolonged when the flow velocity of the water flow remains unchanged, that is, the time required for the water flow to flow out of the water pipe 100 is prolonged, so that when the heat generation per unit time of the heating tube 200 remains unchanged, the extension of the time for the water flow to flow through the water pipe 100 can enable the water in the water pipe 100 to absorb more heat, and then the water pipe 100 can make the water therein reach a higher temperature.

[0051] Accordingly, in order to further improve the instant heating efficiency of the overall structure for water, in the present invention, the heating pipe 200 is also spirally arranged, so that the actual length of the heating pipe 200 is also extended, that is, the volume of the heating pipe 200 is increased; thereby, the power of the heating pipe 200 can be increased, so that the heating pipe 200 generates more heat, and the heating effect of the heating pipe 200 on the water pipe 100 is further improved.

[0052] On the basis of the above, in order to make the heat generated by the heating pipe 200 better absorbed by the water in the water pipe 100, the tube wall of the heating pipe 200 is connected to the tube wall of the water pipe 100; specifically, the outer layer of the water pipe 100 is wrapped with aluminum, which is a good heat transfer material, and the heating pipe 200 is made of metal, so the outer layer of the water pipe 100 can be directly welded to the heating pipe 200, so that when the heating pipe 200 is powered on and generates heat, the heat can be directly transferred to the water pipe 100; however, it should be noted that the heating pipe 200 and the tube wall of the water pipe 100 can also be made by methods such as integral molding to ensure good heat conduction between the two.

[0053] Reference Figures 2 to 4 It should be noted that in the present invention, the heat generated by the traditional single C-type heating tube 200 may cause the local temperature of the water pipe 100 to be too high, so that the water flow may be vaporized when flowing through the area with too high temperature in the water pipe 100, affecting the water outlet effect of the water pipe 100; therefore, in order to ensure the stability of the water outlet performance of the overall structure, the heating tube 200 is also spirally arranged, and the number of spiral circles of the heating tube 200 is equal to the number of spiral circles of the water pipe 100, that is, the actual length of the heating tube 200 is similar to the length of the water pipe 100, so that the tube wall of the heating tube 200 can correspond to the tube wall of the water pipe 100, so that the heat emitted by the heating tube 200 can be evenly transferred to the water pipe 100, and then the water in the water pipe 100 can be evenly heated, ensuring the stability of the water outlet performance of the water pipe 100.

[0054] It should be noted that the actual power of the heating tube 200 can be adjusted according to the actual water outlet temperature requirement of the water pipe 100, that is, when the water outlet temperature requirement of the water pipe 100 is low, the voltage and current on the heating tube 200 can be reduced to reduce the heat generated by the heating tube 200 to adapt to the actual temperature requirement; correspondingly, when the water outlet temperature requirement of the water pipe 100 is low, the voltage and current on the heating tube 200 are increased to increase the heat generated by the heating tube 200.

[0055] In the present invention, based on the above idea, the number of the heating tubes 200 can be adjusted to improve the heating effect of the heating tubes 200 on the water pipe 100 .

[0056] Reference Figures 5 to 7 Specifically, the present invention further proposes a liquid heating container, comprising a water pipe 100 and two heating pipes 200. The water pipe 100 is also connected to the inner tank of the beverage processing equipment, and the water pipe 100 is also spirally arranged, so the water pipe 100 has the same effect as the above-mentioned heating device in the present invention, which will not be described in detail here.

[0057] The difference from the above-mentioned heating device is that the heating device proposed in the present invention includes two heating tubes 200, both of which are ring-shaped with a notch, that is, both ends of the two heating tubes 200 are at the notch to facilitate electrical connection with the outside world; accordingly, in order to enable the two heating tubes 200 to heat the water pipe 100 without interfering with each other, the two heating tubes 200 include a first heating tube 200a and a second heating tube 200b, and the ring diameter of the first heating tube 200a is smaller than that of the second heating tube 200b; specifically, the outer ring diameter of the ring formed by the first heating tube 200a is smaller than the inner ring diameter of the ring formed by the second heating tube 200b, so that the installation and heating process of the first heating tube 200a will not affect the second heating tube 200b.

[0058] Reference Figures 5 to 7 In another embodiment of the present invention, the tube walls of the first heating tube 200a and the second heating tube 200b are both connected to the tube wall of the water pipe 100; similar to the above-mentioned heating device, the outer layer of the water pipe 100 in the heating device proposed by the present invention is also wrapped with aluminum, and the tube walls of the first heating tube 200a and the tube walls of the second heating tube 200b are respectively welded to the tube walls of the water pipe 100, that is, from a certain viewing angle, the first heating tube 200a is approximately arranged in the inner circle of the second heating tube 200b, which can be more commonly described as the second heating tube 200b is sleeved on the outer periphery of the first heating tube 200a, but there is no direct connection between the first heating tube 200a and the second heating tube 200b.

[0059] The arrangement of the first heating tube 200a and the second heating tube 200b also increases the amount of heat that the water pipe 100 can absorb in disguise, so that the water in the water pipe 100 can also absorb more heat, thereby increasing the upper temperature limit that the water in the water pipe 100 can reach; and it should be noted that, compared with the traditional single C-type heating tube 200, the cooperation of the first heating tube 200a and the second heating tube 200b can also reduce the possibility that the local temperature of the water pipe 100 is too high, thereby reducing the possibility that the water will vaporize when flowing through the area with too high temperature in the water pipe 100; specifically, the arrangement of the first heating tube 200a and the second heating tube 200b similar to a sleeve allows most areas on the water pipe 100 to be heated, so that when the outlet water temperature requirement of the water pipe 100 is high, the simultaneous heating of the first heating tube 200a and the second heating tube 200b can meet the heat requirement for the water in the water pipe 100 to reach the required temperature, but will not generate excessive heat locally to vaporize the water in the area, thereby ensuring the water outlet effect of the water pipe 100.

[0060] Reference Figures 5 to 7In this embodiment, in order to make the water pipe 100 heated more evenly, the direction of the notch of the first heating tube 200a is opposite to the direction of the notch of the second heating tube 200b, that is, the water pipe 100 at the notch of the first heating tube 200a will be heated by the second heating tube 200b, and similarly, the water pipe 100 at the notch of the second heating tube 200b will be heated by the first heating tube 200a, so that the water pipe 100 is heated more evenly.

[0061] In combination with the above description, it should be noted that in order to better utilize the heat, a heat transfer aluminum plate 300 is generally provided at the bottom of the inner tank to transfer the heat on the heating pipe 200 or the water pipe 100 to the inner tank, thereby maximizing the utilization of heat.

[0062] In the above two heating devices, a heat transfer aluminum plate 300 is provided at the bottom of the inner tank, the water pipe 100 is spirally arranged on the heat transfer aluminum plate 300, and the heating pipe 200 is arranged on the water pipe 100 and is not directly connected to the heat transfer aluminum plate 300, that is, the water pipe 100 is arranged between the heat transfer aluminum plate 300 and the heating pipe 200; the first heating pipe 200a and the second heating pipe 200b are also arranged on the water pipe 100 and are not directly connected to the heat transfer aluminum plate 300, that is, the water pipe 100 is arranged between the first heating pipe 200a, the second heating pipe 200b and the heat transfer aluminum plate 300. Specifically, in order to ensure the normal use of the heating function, the water pipe 100 can be used to heat the entire inner pot; that is, in the heating mode, the heating pipe 200, or the first heating pipe 200a and the second heating pipe 200b also heat the water pipe 100, but the water pipe 100 does not discharge water at this time; since the temperature generated by the heating pipe 200, or the first heating pipe 200a and the second heating pipe 200b is relatively high, the water pipe 100 will also have a relatively high temperature, which may exceed the boiling point of water, so that the water in the water pipe 100 will form steam, and the steam will pass through the water pipe 100 0 returns to the inner pot, and then stirs the water in the inner pot that heats up slowly. The steam exchanges heat with the water in the inner pot during the stirring process, and the inner pot is generally sealed during the heating process, so the steam will cause the water in the inner pot to heat up, and the stirring effect of the steam on the water in the inner pot will also accelerate the heat transfer, so that the water in the inner pot can heat up quickly; at the same time, the heat on the water pipe 100 will be transferred to the heat transfer aluminum plate 300, and the heat transfer aluminum plate 300 will transfer the heat to the inner pot to further heat the inner pot; this setting can maximize the use of heat.

[0063] Reference Figures 8 to 10 In the case where the first heating tube 200 a and the second heating tube 200 b are provided, the heat transfer aluminum plate 300 can be adjusted to change the installation positions of the first heating tube 200 a and the second heating tube 200 b.

[0064] In another embodiment of the present invention, specifically, the water pipe 100 is also spirally arranged on the heat transfer aluminum plate 300, and the tube wall of the second heating tube 200b is also connected to the tube wall of the water pipe 100, that is, the tube wall of the second heating tube 200b is welded to the water pipe 100, and the water pipe 100 is arranged between the second heating tube 200b and the heat transfer aluminum plate 300, which means that the second heating tube 200b is arranged on the water pipe 100 but not directly connected to the heat transfer aluminum plate 300, and the heat generated by the second heating tube 200b needs to be transferred to the heat transfer aluminum plate 300 through the water pipe 100.

[0065] Reference Figures 10 to 13 In order to allow as much heat as possible to be absorbed by the water in the water pipe 100 under the instant heating function, a heat transfer ring 310 is provided on the outer periphery of the heat transfer aluminum plate 300, and a connecting step 320 is provided between the heat transfer ring 310 and the heat transfer aluminum plate 300, or a plurality of heat insulating hollows 330 are opened on the heat transfer ring 310, so that there is a gap between the heat transfer ring 310 and the bottom of the inner tank. Since the heat transfer efficiency of air is much lower than that of metal, the existence of the gap will greatly reduce the direct heat exchange between the heat transfer ring 310 and the bottom of the inner tank, so that the heat on the heat transfer ring 310 can only be transferred to the inner tank through the heat transfer aluminum plate 300, thereby limiting the efficiency of the heat transfer from the heat transfer ring 310 to the heat transfer aluminum plate 300.

[0066] Based on the above, the water pipe 100 is spirally arranged on the heat transfer coil 310, and the water pipe 100 is arranged on the outer side of the heat transfer coil 310, so that when the instant heating function is started, the water in the water pipe 100 is heated first; and the first heating pipe is also arranged on the heat transfer coil 310, and the first heating pipe is arranged on the inner side of the heat transfer coil 310; when the water pipe 100 needs to be heated, the second heating pipe 200b directly heats the water pipe 100, and the first heating pipe 200a heats the water pipe 100 through the heat transfer coil 310, thereby forming a double-sided heating effect on the water pipe 100 in disguise.

[0067] It should be noted that the heat transfer aluminum plate 300 and the heat transfer ring 310 can be integrally formed by stamping, or can be manufactured by methods such as welding, and the first heating tube 200 a is welded to the heat transfer ring 310 .

[0068] Reference Figure 4 , Figure 7 and Fig.10In order to ensure the heating effect of the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b on the water pipe 100, and to facilitate welding the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b to the water pipe 100, or to facilitate welding the first heat pipe 200a to the heat transfer ring 310, the cross section of the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b perpendicular to the extension direction thereof is a quadrilateral, so that the heat pipe 200 0, or the first heating tube 200a and the second heating tube 200b can be provided with one side as a contact surface 210, so as to facilitate welding the water pipe 100 to the heating tube 200, or the first heating tube 200a and the second heating tube 200b; further, the heating tube 200, or the first heating tube 200a and the second heating tube 200b can be square, rectangular, rhombus or trapezoidal; in this embodiment, in order to maintain the heating tube 200, or the first heating tube 200a and the second heating tube 200b In order to maintain the heating effect of the heating tube 200, or the first heating tube 200a and the second heating tube 200b, and to maximize the contact area 210 between the heating tube 200, or the first heating tube 200a and the second heating tube 200b and the water pipe 100, the cross section of the heating tube 200, or the first heating tube 200a and the second heating tube 200b perpendicular to the extension direction thereof is a trapezoid, and the lower bottom surface of the trapezoid is the heating tube 200, or the first heating tube 200a and the second heating tube 200b. b, the trapezoidal arrangement enables the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b to have a larger contact surface 210 with the water pipe 100 without reducing the volume, so that the heat transfer effect between the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b and the water pipe 100 can be improved as much as possible while ensuring the heating effect of the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b;In order to ensure that the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b have the largest contact surface 210 while ensuring the compatibility between the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b and other structures, the cross section of the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b perpendicular to its extension direction is an isosceles trapezoid, so that the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b can have the largest contact surface 210 (that is, the lower bottom surface of the cross section of the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b) while also having an installation surface that is compatible with other structures (that is, the upper bottom surface of the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b), so that the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b can have a maximum contact surface 210 after installation. The mounting surface matched with other structures makes it difficult for the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b to shake after installation and matching with other structures, thereby improving the stability of the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b; and the setting of the mounting surface facilitates the heat insulation of the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b, thereby improving the stability of the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b, while reducing the possibility of the heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b directly contacting with other structures during use, thereby reducing the possibility of other structures contacting with the high-temperature heat pipe 200, or the first heat pipe 200a and the second heat pipe 200b and melting or even catching fire, further improving the safety of the overall structure. ;

[0069] It should be noted that, in different application modes, the length ratio between the upper bottom surface and the lower bottom surface of the heating tube 200, or the first heating tube 200a and the second heating tube 200b can be adjusted, that is, the overall shape of the heating tube 200, or the first heating tube 200a and the second heating tube 200b can be adjusted to improve the adaptability of the overall structure; and in the utility model, in order to further improve the adaptability of the overall structure, the cross-sectional area of ​​the first heating tube 200a in its extension direction is smaller than the cross-sectional area of ​​the second heating tube 200b in its extension direction, so as to ensure that the second heating tube 200b can be sleeved on the outer ring of the first heating tube 200a without interfering with each other.

[0070] The utility model also proposes a thermos, which includes the two heating devices mentioned above. The specific structures of the two heating devices refer to the above embodiments.
