Description

Technical Field

[0001] This utility model relates to the field of tea bar machine technology, and in particular to a water guiding structure for an instant hot tea bar machine and the tea bar machine thereof. Background Technology

[0002] Existing instant hot water dispensers commonly suffer from a "dead water zone" problem in their water path design between the heating element and the water outlet, severely restricting drinking water hygiene and safety as well as the stability of thermal efficiency. In traditional structures, the main heating element's water outlet is usually directly connected to the water outlet via a straight-through pipe, or a simple branched water path is used to achieve dual-mode hot and cold water supply. With this design, after the water path is closed, approximately 50-150ml of residual water remains in the horizontal or low-angled pipe from the heating chamber to the water outlet, unable to drain naturally.

[0003] After the main heating element stops, the temperature gradually drops to the 40-60℃ range. This stagnant water remains in a warm and humid environment for an extended period, becoming a breeding ground for bacteria. Laboratory tests show that the total bacterial count can exceed 800 CFU / mL within 72 hours, far exceeding the GB 5749 standard for drinking water. Furthermore, the residual water mixes with newly added cold water during the next heating cycle, causing initial water temperature fluctuations of ±5℃ or more, severely impacting brewing quality. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of stagnant water in the pipeline between the heating component and the water outlet of the existing instant hot tea bar machine, and to provide a water guiding structure for the instant hot tea bar machine and the tea bar machine itself.

[0005] A water guiding structure for an instant hot tea bar machine includes a main heating element and a water outlet. A three-way pipe is sleeved on the water outlet end of the main heating element. One port of the three-way pipe is connected to the water outlet through a first water supply pipe. A water guiding element is connected to the other port of the three-way pipe.

[0006] Furthermore, the height of the water outlet is lower than the height of the T-connector, and the first water supply pipe is inclined; the water guide is configured as a valve, and the water guide is electrically connected to the main control unit of the tea bar machine.

[0007] Furthermore, the water guide is configured as a pump, and the outlet end of the pump is connected to one end of a tee pipe via a second water supply pipe; the pump is electrically connected to the main control unit of the tea bar machine.

[0008] An instant hot tea bar machine has any of the above-mentioned water guiding structures.

[0009] The beneficial effects of this utility model are: by adding a water guide between the main heating element and the water outlet, the residual water in the first water supply pipe can be effectively removed after the water supply is stopped, avoiding the formation of stagnant water and fundamentally eliminating the problem of bacterial growth in a warm and humid environment.

[0014] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0015] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex. Example 1

[0016] like Figure 1 As shown, a water guiding structure for an instant hot tea bar machine includes a main heating element 1 and a water outlet 2. A three-way pipe 3 is sleeved at the water outlet end of the main heating element 1. One port of the three-way pipe 3 is connected to the water outlet 2 via a first water supply pipe 21; the other port of the three-way pipe 3 is connected to a water guiding component 4. Specifically, the main heating element 1 and the water outlet 2 are existing technologies in the field of tea bar machines and will not be elaborated upon here. In this solution, the main heating element 1 is preferably a stainless steel inner tank type rapid heating device, and its water outlet end is threadedly sleeved with a stainless steel three-way pipe 3. Port A of the three-way pipe 3 is vertically connected to the water outlet of the main heating element 1, port B is connected to the water outlet 2 via a food-grade silicone first water supply pipe 21, and port C is connected to the water guiding component 4.

[0017] In this scheme, the height of the water outlet 2 is lower than the height of the three-way pipe 3, and the first water supply pipe 21 is inclined; specifically, the installation height of the water outlet 2 is 2~3cm lower than the center line of the three-way pipe 3, and the first water supply pipe 21 extends downward at an angle of 15°~30°.

[0018] The water guide 4 is configured as a valve and is electrically connected to the main control unit of the tea bar machine. Specifically, the water guide 4 is a normally closed solenoid valve (operating voltage DC12V), and its outlet end is connected to the C interface of the three-way pipe 3 via a quick-connect connector. The main heating element 1 and the solenoid valve are both connected to the control motherboard via wires, and the main control chip coordinates the timing of their actions. In use, when the normally closed solenoid valve (operating voltage DC12V) is opened, the pressure inside the first water supply pipe 21 is the same as the external pressure. Because the first water supply pipe 21 is inclined, the residual water inside the first water supply pipe 21 will flow out from the outlet 2.

[0019] During normal use, the normally closed solenoid valve (operating voltage DC12V) is closed, and a sealed water supply channel is formed between the water outlet 2 and the main heating element 1. The overall operation is the same as the existing water supply process of the tea bar machine.

[0020] The workflow of this solution:

[0021] Heating and dispensing stage: When the user selects the hot water function, the main control chip activates the main heating element 1, while keeping the solenoid valve of the water guide element 4 closed. Cold water is injected from the bottom of the main heating element 1 by the suction pump 5, heated to the set temperature (e.g., 98℃), and then forms vapor pressure, pushing the hot water through the A→B channel of the three-way pipe 3, and discharged from the outlet 2 by gravity along the inclined first water delivery pipe 21. At this time, the C port of the three-way pipe 3 forms a physical stop point due to the closed solenoid valve, ensuring unidirectional water output.

[0022] Shutdown and purging phase: After water discharge, the main heating element 1 stops working, and the solenoid valve of the water guide 4 is opened. At this time, the residual water in the pipeline is at the same pressure at the A and C ports of the tee pipe 3. The 15° inclination angle of the first water supply pipe 21 creates a positional difference between sections B and C. Water in the first water supply pipe 21 continues to flow out from the outlet 2. Experiments show that a single drainage volume can reach 135ml, with only ≤1ml of water droplets remaining on the pipe wall.

[0023] This embodiment achieves zero stagnant water and intelligent drainage by leveraging the multi-directional characteristics of the three-way pipe and the linkage control of the water guiding components, thus possessing the dual advantages of simplified structure and improved hygiene performance. Example 2

[0024] like Figure 2As shown, the structure in this embodiment is the same as that in embodiment 1, except that: the water guide 4 is a pump, and the outlet end of the pump is connected to one end of the tee pipe 3 through the second water supply pipe 41; the pump is electrically connected to the main control unit of the tea bar machine. Specifically, the water guide 4 is a pump, and its inlet end is connected to the outside, allowing air to be drawn into the pump 4. The outlet end of the pump 4 is connected to the second water supply pipe 41, and the second water supply pipe 41 is connected to port C of the tee pipe 3. The pump 4 is electrically connected to the main control board.

[0025] How this solution works:

[0026] Heating and output stage: Cold water is injected from the bottom of the main heating element 1 under the action of the suction pump 5. After being heated to the set temperature (such as 98°C), it forms steam pressure, which pushes the hot water through the A→B channel of the three-way pipe 3 and is discharged from the outlet 2 by gravity acceleration along the inclined first water supply pipe 21. At this time, the pump is not working, and the second water supply pipe 41 is in a closed state.

[0027] Active evacuation stage: When the main heating element 1 stops working and the cavity temperature drops to 50°C, the control board starts the pump 4. The pump 4 draws in outside air and applies pressure to the three-way pipe 3 through the C interface, forcing the remaining water to flow out from the outlet 2 along the first water supply pipe 21.

[0028] This embodiment uses pump 4 to actively regulate pressure, breaking through the tilt angle limitation of traditional gravity drainage. It is especially suitable for horizontally installed or complex water system with multiple bends, and at the same time realizes the lossless transportation and drainage of residual water. Example 3

[0029] like Figure 3 As shown, an instant hot tea bar machine has any of the above-mentioned water guiding structures.

[0030] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
