[0029] An embodiment of the present utility model provides a cup warming structure for a coffee machine. Among them, as Figure 1 and Figure 5 shown, the coffee machine includes a machine body 8 and a heating boiler 2 disposed inside the machine body 8. A heating tube 84 is provided inside the heating boiler 2, and the heating tube 84 can heat the water inside the heating boiler 2 to form hot water and water vapor.

[0030] Among them, the heating boiler 2 is a water storage boiler. During the working process, about half of the water volume is loaded inside the boiler. The heating tube 84 is used to heat the water to boiling to generate steam. The upper half inside the pot is steam, and the lower half is hot water. The steam valve 86 on the coffee machine is connected to the upper part of the boiler to take out steam for use, and the hot water valve 87 on the coffee machine is connected to the lower part of the boiler to take out hot water for use.

[0031] As Figure 1 shown, the cup warming structure of this embodiment mainly includes a cup warming plate 1 and a heating assembly.

[0032] The cup warming plate 1 is disposed on the top cover of the machine body 8. The cup warming plate 1 is used to hold the coffee cup 9, and it can absorb heat to heat the coffee cup 9, thereby realizing the function of warming the coffee cup 9.

[0033] The heating assembly includes a heat conducting water pipe 3, a circulation water pump 4 and a circulation pipeline 5. The heat conducting water pipe 3 is located below the cup warming plate 1. The circulation pipeline 5 communicates the heat conducting water pipe 3, the heating boiler 2 and the circulation water pump 4. The circulation pipeline 5 is connected to the lower half of the heating boiler 2.

[0034] The circulation water pump 4 is used to pump the hot water inside the heating boiler 2 into the heat conducting water pipe 3 through the circulation pipeline 5, and then flow back into the heating boiler 2. The heat of the hot water in the heat conducting water pipe 3 can be transferred to the cup warming plate 1, and the cup warming plate 1 absorbs the heat and becomes hot to heat the coffee cup 9.

[0035] The cup warming structure of the utility model can utilize the hot water in the heating boiler 2 to flow into the heat conducting water pipe 3, and the heat generated by the heat conducting water pipe 3 is transferred to the cup warming plate 1, thereby warming the coffee cup 9 placed on the cup warming plate 1. The cup warming structure has fast heat conduction efficiency and improves the cup warming effect.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments, the hot water pipe 3 abuts against the bottom surface of the cup warming plate 1 . The hot water pipe 3 abuts against the cup warming plate 1 , and the heat transfer efficiency can be improved.

[0037] In some embodiments, the cup warming structure further includes a fixing frame 6 , which is connected to the cup warming plate 1 to fix the hot water pipe 3 on the cup warming plate 1 .

[0038] Among them, the fixing frame 6 is located on the side of the hot water pipe 3 away from the cup warming plate 1. The fixing frame 6 is provided with a slot for clamping the hot water pipe 3. Through the connection between the fixing frame 6 and the cup warming plate 1, the hot water pipe 3 can be directly fixed on the cup warming plate 1.

[0039] The structure of the fixing frame 6 in this embodiment is not specifically limited, and its specific shape can be determined according to the structure of the hot water pipe 3 .

[0040] As for the connection structure between the fixing frame 6 and the cup warming plate 1 , there is no specific limitation, and it can be a bolt connection or a clamping connection.

[0041] In some embodiments, Figure 2 and Figure 3 As shown, the cup warming structure further includes a thermostat 7 and a controller (not shown in the figure). The thermostat 7 is fixed on the cup warming plate 1 and is used to detect the temperature of the cup warming plate 1.

[0042] The controller is electrically connected to the thermostat 7 and the circulating water pump 4. The thermostat 7 is used to detect the temperature of the cup warming plate 1 and transmit the detected temperature to the controller.

[0043] The controller can receive the temperature transmitted by the thermostat 7, and when the detected temperature exceeds the preset first temperature (such as 55 degrees), control the circulating water pump 4 to stop pumping water, thereby preventing the cup warming plate 1 from overheating. Or when the detected temperature is lower than the preset second temperature (such as 55 degrees), control the circulating water pump 4 to start pumping water, thereby preventing the cup warming plate 1 from being too hot and unable to achieve the cup warming function. It should be noted that the preset first temperature and second temperature are not specifically limited and can be determined according to user needs.

[0044] By providing the thermostat 7 and the controller, the start and stop of the circulating water pump 4 can be controlled according to whether the temperature of the cup warming plate 1 reaches a specified temperature.

[0045] In some embodiments, the heat-conducting water pipe 3 may include at least two interconnected pipe groups. For example, the number of pipe groups is three, and each pipe group corresponds to a region of the warming cup plate 1, that is, each pipe group is used to heat the corresponding region.

[0046] Coffee cups 9 can be respectively placed in the regions corresponding to the three pipe groups, so that the three coffee cups 9 can be heated simultaneously.

[0047] Of course, the number of pipe groups can also be more than three, which can be determined according to the sizes of the warming cup plate and the coffee cups.

[0048] In some embodiments, words for reminding users to place the coffee cups 9, such as "warming cup area" and the like, can be marked on the upper surface of the warming cup plate 1 in the regions corresponding to the three pipe groups respectively, so that users can know in which region to place the coffee cups 9.

[0049] Preferably, as Figure 4 shown, the shape of each pipe group in the heat-conducting water pipe 3 of this embodiment can be respectively a vortex shape. The entire outer diameter of the vortex-shaped pipe group is larger than the outer diameter of the coffee cup 9. The pipe group with this structure can increase the contact area between the pipe group and the warming cup plate 1, thereby improving the heat transfer effect.

[0050] In some other embodiments, the heat-conducting water pipe 3 can also be an S-shaped water pipe as a whole, as shown in Figure 2 and Figure 3 shown. Through this heat-conducting water pipe 3, the entire warming cup plate 1 can be heated, so that the coffee cups 9 can be placed in any region on the warming cup plate 1 for heating.

[0051] In some embodiments, cup positioning grooves (not shown in the figure) corresponding to the multiple pipe groups one by one can be provided on the upper surface of the warming cup plate 1. The bottom of the coffee cup 9 can be embedded into the positioning grooves, so as to ensure the stability of the coffee cup 9 placed on the warming cup plate 1.

[0052] In some embodiments, the warming cup structure further includes a heat reflection plate (not shown in the figure), and this heat reflection plate is located below the heat-conducting water pipe 3 and fixed on the warming cup plate 1.

[0053] A layer of heat-reflecting material can be provided on the surface of the heat reflection plate facing the heat-conducting water pipe 3. This heat reflection plate can reflect the heat radiated by the heat-conducting water pipe 3 upward, so as to ensure that most of the heat of the heat-conducting water pipe 3 is transferred to the warming cup plate 1, thereby improving the heating efficiency of the warming cup plate 1. The specific structure of the heat reflection plate is not specifically limited in the embodiments of the present invention.

[0054] In some embodiments, a notch for placing the warming cup plate 1 can be provided on the top cover of the coffee machine body 8, and the warming cup plate 1 covers this notch and is coplanar with the top cover.

[0055] A sealing ring is provided between the warming cup plate 1 and the top cover. Through this sealing ring, the water on the warming cup plate 1 can be prevented from flowing into the coffee machine, thus ensuring the sealing of the connection between the two.

[0056] As Figure 5 shown, this embodiment also provides a coffee machine, which includes a warming cup structure for a coffee machine described in any one of the above embodiments.

[0057] In the coffee machine of this embodiment, the warming cup plate 1 is located above the heating boiler 2, and the warming cup plate 1 can also be assisted in heating by the heat radiation on the surface of the heating boiler 2.

[0058] As Figure 1 shown, in some embodiments, a water inlet pipeline 88 connected to the heating boiler 2 is also provided on the coffee machine. An inlet water joint 80 is connected to the port of the water inlet pipeline 88. Through this inlet water joint 80, a tap water faucet 85 can be connected, so that the drinking water to be heated can be injected into the heating boiler 2 through the water inlet pipeline 88.

[0059] In some embodiments, an inlet water pressure reducing valve 81, an inlet water solenoid valve 82 and a booster pump 83 are sequentially provided on the water inlet pipeline 88 along the water flow direction. The inlet water pressure reducing valve 81 is used to reduce the pressure of the drinking water flowing into the water inlet pipeline 88 through the tap water faucet 85. The inlet water solenoid valve 82 is used to control the on-off of the water inlet pipeline 88. The booster pump 83 can boost the drinking water in the water inlet pipeline 88 and then pump it into the heating boiler 2.
