[0042] 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.
[0043] 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.
[0044] Reference Figures 1 to 4 In order to solve the above problems, the utility model proposes a heating device, including an instant hot water pipe 100, a heating pipe 200 and a heat transfer aluminum plate 300; wherein the instant hot water pipe 100 is used to discharge water, the heating pipe 200 is used to heat the instant hot water pipe 100, and the heat transfer aluminum plate 300 is used to transfer the heat on the instant hot water pipe 100 to the inner pot; specifically, the heat transfer aluminum plate 300 is arranged at the bottom of the inner pot, the instant hot water pipe 100 is arranged on the side of the heat transfer aluminum plate 300 away from the inner pot, and the heating pipe 200 is arranged on the instant hot water pipe 100 and the heating pipe 200 is not in direct contact with the heat transfer aluminum plate 300, so that the heat generated by the heating pipe 200 needs to be transferred to the heat transfer aluminum plate 300 via the instant hot water pipe 100, and then further transferred to the inner pot. As a result, the heat generated by the heating pipe 200 will be first absorbed by the instant hot water pipe 100, thereby completing the heating of the liquid in the instant hot water pipe 100.
[0045] However, after the instant hot water pipe 100 is heated, a portion of the heat will still be transferred to the heat transfer aluminum plate 300 through the instant hot water pipe 100, and then absorbed by the inner tank; and the inner tank is large in volume and contains a large amount of liquid, so under the effect of the temperature difference, a large amount of heat will still be absorbed by the inner tank, thereby limiting the upper temperature limit of the instant hot water pipe 100; for this reason, the utility model is provided with a heat conducting structure 310 on the heat transfer aluminum plate 300, and the heat conducting structure 310 is used to reduce the amount of heat transferred from the instant hot water pipe 100 to the heat transfer aluminum plate 300, but does not prevent the heat from being transferred from the instant hot water pipe 100 to the heat transfer aluminum plate 300, thereby maintaining the heating function of the heating tube 200 on the inner tank, while reducing the amount of heat transferred to the heat transfer aluminum plate 300 through the instant hot water pipe 100 under the instant heating function state, thereby allowing more heat to be gathered on the instant hot water pipe 100, thereby increasing the upper temperature limit of the instant hot water pipe 100.
[0046] It should be noted that the heat-conducting structure 310 can increase the upper temperature limit of the instant hot water pipe 100 while also increasing the water outlet speed of the instant hot water pipe 100, that is, reducing the time required for the instant hot water pipe 100 to heat up to the set temperature. Specifically, through the heat-conducting structure 310, more heat is collected on the instant hot water pipe 100 and is not easy to dissipate, so that the instant hot water pipe 100 heats up faster, and then at the corresponding set temperature, the instant hot water pipe 100 can reach the set temperature faster, that is, the instant hot water pipe 100 has a higher water outlet speed.
[0047] In addition, in order to ensure the heat retention effect of the heat-conducting structure 310, in the utility model, the heat transfer aluminum plate 300 is arranged on the bottom wall of the inner pot, so that in the direction perpendicular to the plane where the heat transfer aluminum plate 300 is located, the projection area of the heat-conducting structure 310 on the bottom wall is smaller than the projection area of the heating pipe 200 on the bottom wall, thereby limiting the heat transferred to the inner pot through the heat-conducting structure 310 as much as possible.
[0048] In this embodiment, in order to further increase the upper temperature limit that the hot water pipe 100 can reach, the hot water pipe 100 has a certain length so that the hot water pipe 100 can be spirally arranged on the heat transfer aluminum plate 300, thereby extending the heating time of the water in the hot water pipe 100, and then the water in the hot water pipe 100 can obtain more heat and have a higher temperature.
[0049] In order to achieve a good heating effect for the spirally arranged instant hot water pipe 100, that is, when the water flows in the instant hot water pipe 100, the water can be heated and absorb heat all the time, the diameter of the heating pipe 200 in this embodiment is larger than the diameter of the instant hot water pipe 100; since the instant hot water pipe 100 is spirally arranged, the contact surface 210 of the heating pipe 200 and the instant hot water pipe 100 is increased, thereby improving the heat transfer efficiency between the heating pipe 200 and the instant hot water pipe 100; in the actual application process, that is, in a unit time, after being heated by the heating pipe 200, the water in the instant hot water pipe 100 can reach a higher temperature, that is, the heating effect of the heating pipe 200 on the instant hot water pipe 100 is improved.
[0050] In this embodiment, in order to better transfer the heat generated by the heating tube 200 to the instant hot water pipe 100, a contact surface 210 is provided on the heating tube 200, and the instant hot water pipe 100 is connected to the contact surface 210; specifically, the outer layer of the instant hot water pipe 100 is wrapped with aluminum, which is a good heat transfer material, and the heating tube 200 is made of metal, so the outer layer of the instant hot water pipe 100 can be directly welded to the heating tube 200, so that when the heating tube 200 is powered on and generates heat, the heat can be directly transferred to the instant hot water pipe 100. Further, the contact surface 210 provided on the heating tube 200 facilitates the welding of the instant hot water pipe 100 to the heating tube 200 during installation, thereby improving the convenience of the overall structure during assembly; and the provision of the contact surface 210 can increase the contact surface 210 area after the heating tube 200 and the instant hot water pipe 100 are welded, so as to facilitate better heat transfer.
[0051] It should be noted that, in order to make the heating tube 200 have a contact surface 210, in the present embodiment, the heating tube 200 is annular and has a notch, and an electrode can be installed at the notch to connect the circuit, so that the heating tube 200 can generate heat by using the current; and the cross section of the heating tube 200 perpendicular to its extension direction is a quadrilateral, so that the heating tube 200 can be set to have one side as the contact surface 210, which is convenient for welding the instant hot water pipe 100 to the heating tube 200. Furthermore, the heating tube 200 can be square, rectangular, rhombus or trapezoidal. In this embodiment, in order to maintain the volume of the heating tube 200, that is, to maintain the heating effect of the heating tube 200, and at the same time maximize the contact surface 210 area between the heating tube 200 and the instant hot water pipe 100, the cross section of the heating tube 200 perpendicular to its extension direction is a trapezoid, and the lower bottom surface of the trapezoid is the contact surface 210 of the heating tube 200. The trapezoidal setting enables the heating tube 200 to have a larger contact surface 210 area with the instant hot water pipe 100 without reducing the volume, so that the heating effect of the heating tube 200 can be guaranteed while the heating effect of the heating tube 200 can be guaranteed. The heat transfer effect between the heating pipe 200 and the instant hot water pipe 100 is improved as much as possible; and in order to make the heating pipe 200 have the largest contact surface 210 while ensuring the compatibility between the heating pipe 200 and other structures, the cross section of the heating pipe 200 perpendicular to its extension direction is an isosceles trapezoid, so that the heating pipe 200 can have the largest contact surface 210 (that is, the lower bottom surface of the cross section of the heating pipe 200) and also have a mounting surface (that is, the upper bottom surface of the heating pipe 200) that is compatible with other structures, and then the heating pipe 200 can have a mounting surface that is compatible with other structures after installation, so that the heating pipe 200 is not easy to shake after installation and matching with other structures, thereby improving the stability of the heating pipe 200; and the setting of the mounting surface facilitates the heat insulation of the heating pipe 200, thereby improving the stability of the heating pipe 200 while reducing the possibility of direct contact between the heating pipe 200 and other structures during use, thereby reducing the possibility of other structures contacting with the high-temperature heating pipe 200 and melting or even catching fire, and further improving the safety of the overall structure.
[0052] Reference Figures 4 to 6In a certain embodiment of the utility model, the heat-conducting structure 310 includes a heat-conducting ring 311 and a plurality of heat-conducting ribs 312, one end of the plurality of heat-conducting ribs 312 is arranged on the heat-conducting aluminum plate 300 at intervals, and the other end of the plurality of heat-conducting ribs 312 is connected to the heat-conducting ring 311; in this embodiment, the hot water pipe 100 is connected to the heat-conducting ribs 312 and the heat-conducting ring 311, so that the heat emitted by the hot water pipe 100 will be transferred to the heat-conducting aluminum plate 300 via the heat-conducting ribs 312 and the heat-conducting ring 311, and then the arrangement of the heat-conducting ribs 312 and the heat-conducting ring 311 can complete the heat transfer between the hot water pipe 100 and the heat-conducting aluminum plate 300. When the heat is applied to the hot water pipe 100, the heat transferred to the heat transfer aluminum plate 300 is reduced; specifically, a heat insulation space is formed between two adjacent heat conductive ribs 312, and the heat insulation space is filled with air, and the heat conductivity of air is low, thereby reducing the heat transfer between the hot water pipe 100 and the heat transfer aluminum plate 300; from another perspective, the provision of the heat conductive ribs 312 and the heat conductive ring 311 reduces the contact area between the heat transfer aluminum plate 300 and the hot water pipe 100, thereby reducing the heat transfer between the hot water pipe 100 and the heat transfer aluminum plate 300, thereby reducing the heat loss from the hot water pipe 100 and increasing the temperature upper limit of the hot water pipe 100.
[0053] In this embodiment, the instant hot water pipe 100 is connected to the thermal ribs 312 and the thermal ring 311, specifically by welding; the thermal ribs 312 and the thermal ring 311 are also made of metal; based on the above description that the outer metal of the instant hot water pipe 100 is aluminum, the welding of the thermal ribs 312 and the thermal ring 311 with the instant hot water pipe 100 can ensure that heat is transferred from the instant hot water pipe 100 to the thermal ring 311 and the thermal ribs 312, and then transferred to the heat transfer aluminum plate 300 via the thermal ring 311 and the thermal ribs 312, and finally transferred to the inner tank to heat the liquid in the inner tank.
[0054] However, it should be noted that, in the present embodiment, the heat transfer aluminum plate 300 is circular, and the diameter of the heat conductive ring 311 is larger than the diameter of the heat transfer aluminum plate 300, so that the heat conductive ring 311 can be arranged on the outer periphery of the heat transfer aluminum plate 300, and the heat conductive rib 312 is connected between the heat conductive ring 311 and the heat transfer aluminum plate 300; specifically, the heat conductive rib 312, the heat conductive ring 311 and the heat transfer aluminum plate 300 can be manufactured using a stamping process, and the heat conductive ring 311 and the heat conductive rib 312 are stamped out from a whole circular aluminum plate to form the heat transfer aluminum plate 300 and the heat conductive structure 310; alternatively, the heat conductive ring 311 and the heat conductive rib 312 can be manufactured using a casting or other integrated molding process, all of which can achieve the same effect.
[0055] It should be emphasized that, based on the above description, the arrangement of the heat-conducting ribs 312 and the heat-conducting rings 311 can reduce the heat transferred to the inner pot via the instant hot water pipe 100 while not completely blocking the process of heat being transferred to the inner pot via the instant hot water pipe 100; from the perspective of the overall beverage processing equipment, it means that while strengthening the instant heating function of the beverage processing equipment, the heating function of the beverage processing equipment is retained.
[0056] Reference Figures 7 to 11 In another embodiment of the utility model, the heat transfer aluminum plate 300 can also be circular as a whole, and the heat conductive structure 310 is configured as a heat transfer ring 313, the inner ring diameter of the heat transfer ring 313 is larger than the diameter of the heat transfer aluminum plate 300, and the heat transfer ring 313 is connected to the outer periphery of the heat transfer aluminum plate 300; the heat transfer ring 313 is also connected to the instant hot water pipe 100, so that the heat transfer ring 313 can transfer the heat on the instant hot water pipe 100 to the heat transfer aluminum plate 300, and then transfer it to the inner tank via the heat transfer aluminum plate 300 to increase the temperature of the liquid in the inner tank.
[0057] Based on the idea of reducing the amount of heat transferred from the instant hot water pipe 100 to the heat transfer aluminum plate 300, a connector 314 is provided between the heat transfer coil 313 and the heat transfer aluminum plate 300. The connector 314 is used to connect the inner ring of the heat transfer coil 313 and the outer edge of the heat transfer aluminum plate 300. It should be noted that the arrangement of the connector 314 makes the heat transfer coil 313 and the heat transfer aluminum plate 300 in a step-like shape, that is, there will be a certain height difference between the heat transfer coil 313 and the heat transfer aluminum plate 300 in the vertical direction, so that there will be a gap between the instant hot water pipe 100 and the inner tank; due to the poor heat transfer efficiency of air, most of the heat transferred from the instant hot water pipe 100 to the heat transfer coil 313 can only be transferred to the heat transfer aluminum plate 300 through the connector 314, which limits the efficiency of heat transfer from the heat transfer coil 313 to the heat transfer aluminum plate 300.
[0058] In this embodiment, the connecting member 314 is ring-shaped, that is, the connecting member 314 has an inner ring, an outer ring and two opposite side surfaces, and the inner ring and the outer ring are both located between the two side surfaces; in this embodiment, the heat transfer aluminum plate 300 is connected to the inner ring of the connecting member 314, and the top surface of the heat transfer aluminum plate 300 is flush with the side surface of the connecting member 314 with a relatively higher height, while the inner ring of the heat transfer ring 313 is connected to the outer ring of the connecting member 314, and the top surface of the heat transfer ring 313 is flush with the other side surface of the connecting member 314 with a relatively lower height, so that the height difference between the heat transfer ring 313 and the heat transfer aluminum plate 300 is the thickness of the connecting member 314 itself.
[0059] It should be noted that the heat transfer aluminum plate 300, the heat transfer ring 313 and the connecting piece 314 can also be manufactured by an integrated molding method. Furthermore, the heat transfer aluminum plate 300, the heat transfer ring 313 and the connecting piece 314 can be manufactured by stamping. That is, a whole piece of aluminum plate can be used to stamp out the heat transfer aluminum plate 300, the heat transfer ring 313 and the connecting piece 314 by a stamping process, and the height difference between the heat transfer aluminum plate 300 and the heat transfer ring 313 can be stamped out.
[0060] In combination with the above, the heating device proposed in the utility model can retain the heating function of the inner tank while allowing the instant hot water pipe 100 to collect more heat generated by the heating tube 200, that is, it can increase the upper limit of the temperature that the instant hot water pipe 100 can heat, or in other words, at the same set temperature, reduce the time required for the instant hot water pipe 100 to heat water to the set temperature.
[0061] The utility model also proposes a hot water kettle, which includes the above-mentioned heating device and an inner tank. The specific structure of the heating device refers to the above-mentioned embodiment. Since the present hot water kettle adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. However, it should be noted that in order to ensure the normal use of the heating function, the instant hot water pipe 100 can be used to heat the inner tank as a whole; that is, in the heating mode, the heating tube 200 also heats the instant hot water pipe 100, but the instant hot water pipe 100 does not discharge water at this time; since the temperature generated by the heating tube is relatively high, the instant hot water pipe 100 will also have a relatively high temperature, which can exceed the boiling point of water, so that the water in the instant hot water pipe 100 will form steam, and the steam will return to the inner tank through the instant hot water pipe 100, thereby stirring the slower temperature rise in the inner tank. The steam in the inner pot is heated by the water in the water pipe 100, and the stirring process of the steam will exchange heat with the water in the inner pot. The inner pot is generally sealed during the heating process, so that the steam will cause the water in the inner pot to heat up. 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 hot water pipe 100 will be transferred to the heat transfer aluminum plate 300 via the heat conduction structure 310, and the heat transfer aluminum plate 300 will transfer the heat to the inner pot to further heat the inner pot. This arrangement can maximize the use of heat.
[0062] The utility model also proposes a wall breaking machine, which includes the above-mentioned heating device. The specific structure of the heating device refers to the above-mentioned embodiment. Since the wall breaking machine adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which are not described one by one here; the heating process of the inner tank of the wall breaking machine can also refer to the description of the heating process of the inner tank of the above-mentioned kettle.
[0063] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
