Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to tea bar machine technical field, especially a local heating structure for instant tea bar machine and tea bar machine thereof. BACKGROUND
[0002] The existing tea bar machine heating system usually adopts one-way water conveying structure, and a one-way flow path is formed between the main heating body and the water outlet nozzle through the water conveying pipe. When the user finishes taking water, because the water conveying mode is pump suction, there is un-drained water in the water conveying pipe at this time, and the water is retained in the pipeline due to the lack of a backflow channel, which leads to the following problems:
[0003] The retained water quickly dissipates heat in a stationary state, and the main heating body needs to reheat the cold water as a whole when taking water next time, resulting in repeated energy consumption (experimental data shows that the retained amount in the water conveying pipe after single water taking can reach 50-100 mL, and the repeated heating energy consumption increases by about 15%-20%).
[0004] The long-term retained cold water is prone to breed microorganisms and form a "dead water section", which threatens the drinking water health and safety;
[0005] The main heating body needs to be frequently started and stopped to compensate for the temperature loss after the pipeline cold water is mixed, which aggravates the equipment wear and tear.
[0006] Although some products try to shorten the water conveying distance by optimizing the pipeline layout to reduce the retained amount, due to the one-way water conveying characteristics, the problem of passive cooling and repeated heating of the residual water cannot be fundamentally solved. INVENTION CONTENTS
[0007] The utility model aims at overcoming the problem of high energy consumption and drinking water health caused by the dead water section in the existing water conveying pipe, and provides a local heating structure for instant tea bar machine and a tea bar machine thereof.
[0008] A local heating structure for instant tea bar machine, comprising a main heating body and a water outlet nozzle, a water conveying pipe is connected and arranged between the main heating body and the water outlet nozzle; a heating element is sleeved and arranged on the water conveying pipe.
[0009] Further, the heating element is composed of a heating wire spirally sleeved on the water conveying pipe.
[0010] Further, the heating element comprises tin paper, and a heating wire is wrapped inside the tin paper.
[0011] An instant tea bar machine has any one of the above local heating structures.
[0012] The utility model discloses a beneficial effect is: through setting up heating spare outside water delivery pipe, when user takes water again, heating spare can directly carry out partial heating to the cooling water body that remains in water delivery pipe, need not rely on main heating body repeated heating, effectively reduce the start -stop frequency of main heating body, when taking water again, the residual water of this time will not dilute the hot water that comes out from main heating body, has guaranteed the temperature control of taking water.

[0018] The following through specific concrete example explains the embodiment of the utility model, and the person skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification. The utility model can also be implemented or applied by another different specific embodiment, and each detail in the specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the utility model. It should be noted that the following examples and features in the examples can be combined with each other without conflict.
[0019] It should be noted that the drawings provided in the following examples only illustrate the basic concept of the utility model in a schematic manner, and only show the components related to the utility model in the drawings, not the number, shape and size of the components when actually implemented. The shape, number and proportion of each component in actual implementation can be changed arbitrarily, and the component layout pattern can be more complex. Example 1
[0020] As Figure 1As shown, a local heating structure for an instant hot tea bar machine includes a main heating element 1 and a water outlet 2, with a water supply pipe 3 connecting the main heating element 1 and the water outlet 2; a heating element 4 is sleeved on the water supply pipe 3. Specifically, the main heating element 1 is fixed inside the tea bar machine's flower rack, and the water outlet 2 is installed at the water inlet. The two are connected by a water supply pipe 3 made of food-grade silicone material, with a total length of 4-10cm and a diameter of 8mm.
[0021] In this design, the heating element 4 consists of a heating wire spirally sleeved on the water supply pipe 3. Specifically, a heating wire is spirally sleeved on the water supply pipe 3 between the outlet end of the main heating body 1 and the water outlet 2. The heating wire, made of nickel-chromium alloy with a diameter of 0.5mm, is wound around the outer wall of the water supply pipe 3 with a spiral spacing of 3mm. Through this spiral heating wire structure, the heating element 4 can operate in a low-power mode during non-water intake periods, maintaining the stagnant water temperature in the water supply pipe 3 above the critical antibacterial temperature of 50℃, thus preventing the formation of a "dead water section" due to microbial growth. Compared to traditional solutions, the risk of bacterial growth is reduced by 80%, and no additional antibacterial coating is required, meeting food-grade hygiene standards. Example 2
[0022] like Figures 2-3 As shown, a local heating structure for an instant hot tea bar machine includes a main heating element 1 and a water outlet 2. A water supply pipe 3 is connected between the main heating element 1 and the water outlet 2. A heating element 4 is sleeved on the water supply pipe 3.
[0023] The heating element 4 includes tin foil 41, inside which a heating wire 42 is wrapped. Specifically, the heating wire 42 is configured with a serpentine structure, sandwiched within double layers of tin foil 41 to form a flexible heating band, which is wrapped around the outer wall of the water pipe 3, with the gaps filled by thermally conductive silicone. The composite structure of tin foil 41 wrapping the heating wire 42 can efficiently reflect heat energy, reduce heat loss, and ensure that the heat from the heating element 4 is concentrated on the water in the water pipe 3. At the same time, the surface temperature of the heating wire 42 is evenly diffused through the tin foil layers, avoiding localized high-temperature oxidation. Example 3
[0024] like Figure 4 As shown, an instant hot tea bar machine has any of the above-mentioned local heating structures.
[0025] Preferably, based on this solution, the control logic of the tea bar machine can be set, specifically: the heating element 4 is connected to an independent temperature control module, and two working modes are set: water dispensing mode: when the tea bar machine dispenses water, the heating element 4 operates at full power of 500W to compensate for the water temperature in the water supply pipe 3 in real time; standby mode: when the tea bar machine is not in use, the heating element 4 switches to the heat preservation power of 50W to maintain the water temperature in the pipe ≥55℃.
[0026] In another aspect, the sleeve mounting design of the heating element 4 supports quick disassembly and assembly, and the user can flexibly adjust the coverage area of the heating element, such as the high residual area of the bending part, according to the residual water distribution characteristics of the water supply pipe 3.
[0027] The above-described embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
