Description

Technical Field

[0001] This application relates to the field of coffee machine technology, and more particularly to a coffee machine water tank assembly and a coffee machine. Background Technology

[0002] Coffee machines can use internal or external water sources to provide the water needed for brewing coffee. The water inside the coffee machine is stored in its water tank. The coffee machine is equipped with a brewing module. After the water in the tank is heated, it is supplied to the brewing module. In the brewing module, hot water passes through the coffee grounds to brew coffee liquid. In current coffee machines, the water tank is usually placed directly on the water tank stand. In order to make it convenient for users to remove the water tank to refill, the water tank and the water tank stand are not locked. The water tank is only pressed on the water tank stand by the weight of the water inside. When people use coffee machines to brew coffee, their usual actions such as twisting their bodies or reaching out may touch the water tank and cause it to tip over. The water in the tank will spill out, soaking the countertop, the floor, and people's clothes. This undoubtedly affects people's mood when brewing and drinking coffee, increases the cleaning work, and reduces the user experience. Utility Model Content

[0040] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0041] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] like Figures 1-8 As shown, in a first aspect, this application provides a coffee machine water tank assembly, including a water tank base 1 and a water tank 2; the water tank base 1 has an anti-tipping portion 11, the water tank 2 has a body 21, the top of the body 21 is provided with a water inlet 22, and the bottom edge of the body 21 protrudes downward to form an assembly portion 23; the inner peripheral side of the assembly portion 23 and the outer peripheral side of the anti-tipping portion 11 form an abutment, and the ratio between the vertical engagement length of the assembly portion 23 and the anti-tipping portion 11 and the height of the body 21 is 1 / 12-1 / 8, and / or, the ratio between the vertical engagement length of the anti-tipping portion 11 and the assembly portion 23 and the height of the water tank base 1 is greater than or equal to 1 / 2.

[0044] This application is used in coffee machines as an accessory to provide water when brewing coffee. The application sets the ratio of the mating length of the water tank 2 and the water tank base 1 at the mating position to the height of the water tank 2 or the height of the water tank base 1. The water tank 2 does not need to be locked, and the water tank 2 will not tip over when the user accidentally touches it during the coffee brewing process due to habitual actions such as twisting or reaching out. This allows the user to enjoy the coffee brewing process.

[0045] The water tank 2 and the water tank base 1 are not locked together, and users can easily remove the water tank 2 from the water tank base 1. For example, when the water in the water tank 2 is used up, the user can carry the water tank 2 to refill it, or take the water tank 2 to the bathroom for cleaning. Sometimes, the user can also directly open the water tank cover 3 and use a container to pour water into the water tank 2, in which case it is not necessary to remove the water tank 2 from the water tank base 1.

[0046] When users perform habitual actions, they may inadvertently touch water tank 2, and the direction of the force exerted on water tank 2 is unpredictable. Some users also have pet cats that like to climb on desks and countertops, and in this case, the cat may touch water tank 2, and the direction of the force exerted by the cat on water tank 2 is also unpredictable. Here, it is required that water tank 2 and water tank base 1 can form multiple points of contact, with forces acting at multiple points between water tank 2 and water tank base 1. Water tank base 1 should be able to support water tank 2 and keep it upright and not tip over when subjected to forces from various directions.

[0047] Therefore, any position on the outer periphery of the anti-tipping part 11 of the water tank seat 1 can form an abutting fit with the assembly part 23. Alternatively, the outer periphery of the anti-tipping part 11 can have multiple mating positions, which are distributed at intervals around the center of the anti-tipping part 11, and the anti-tipping part 11 can form an abutting fit with the assembly part 23 at the mating positions.

[0048] So that when the water tank 2 is subjected to external forces from different directions, the water tank base 1 can generate opposite supporting forces on the water tank 2 to resist the external forces and keep the water tank 2 upright and prevent it from tipping over.

[0049] In some embodiments, the outer diameter of the anti-tipping part 11 gradually decreases from bottom to top, and the inner diameter of the assembly part 23 gradually increases from top to bottom. In this way, the user can quickly align the assembly part 23 with the anti-tipping part 11 and quickly assemble the body 21 onto the water tank seat 1.

[0050] The outer peripheral surface of the anti-tipping part 11 is an inclined surface, which is slightly inclined relative to the vertical direction.

[0051] A first oblique line L1 is formed by any position on the outer peripheral surface of the anti-tipping part 11 intersecting with the vertical plane, and a second oblique line L2 is formed by any position on the inner peripheral surface of the assembly part 23 intersecting with the vertical plane. The angle α formed between the first oblique line L1 and the vertical direction is equal to the angle β formed between the second oblique line L2 and the vertical direction, and the angle α is between 0 degrees and 5 degrees. In this way, the outer peripheral surface of the anti-tipping part 11 and the inner peripheral surface of the assembly part 23 can fit well together, and the water tank 2 can be smoothly and quickly assembled on the water tank base 1.

[0052] This can be understood as follows: a vertical plane is used to cut off the anti-tipping part 11 and the assembly part 23. The cross section of the anti-tipping part 11 and the vertical plane have an intersecting line, namely the first oblique line L1. The first oblique line L1 is on the outer peripheral surface of the anti-tipping part 11. Similarly, the cross section of the assembly part 23 and the vertical plane have an intersecting line, namely the second oblique line L2. The second oblique line L2 is on the inner peripheral surface of the assembly part 23. Both the first oblique line L1 and the second oblique line L2 are inclined relative to the vertical direction. The angles between each of them and the vertical direction represent the degree of inclination of the anti-tipping part 11 and the assembly part 23, respectively.

[0053] Users can access clean water or pour water out through the inlet 22, and can also clean the inside of the water tank 2 through the inlet 22. The water tank 2 also includes a water tank cover 3, which is used to seal the inlet 22 to prevent dust and other pollutants from entering the inside of the water tank 2 and contaminating the inner wall of the water tank 2 and the water inside. The water tank cover 3 is rotatably connected to an adapter 4. The other end of the adapter 4 is rotatably connected to the inside of the main body 21 at the inlet 22. When the water tank cover 3 is on the inlet 22, the adapter 4 is located inside the main body 21 and cannot be seen by the user. In this way, the main body 21 and the water tank cover 3 make the entire water tank 2 look unified and coordinated, and visually more beautiful.

[0054] The water tank base 1 also has a support portion 13 and a boss 12. The support portion 13 is located below the anti-tipping portion 11. A step 14 is formed between the support portion 13 and the anti-tipping portion 11. The bottom end of the mounting portion 23 abuts against the step surface of the step 14. The vertical mating length between the anti-tipping portion 11 and the mounting portion 23 is 20mm to 40mm. The boss 12 is formed on the top surface of the anti-tipping portion 11. A recess 24 is formed on the outer bottom surface of the body 21. The recess 24 and the boss 12 match, and the vertical mating length between the recess 24 and the boss 12 is at least 15mm. In this way, the assembly between the body 21 of the water tank 2 and the water tank base 1 is more secure.

[0055] The portion of the recess 24 within the body 21 protrudes relative to the inner bottom surface of the body 21. That is, the recess 24 formed by the inward indentation of the outer bottom surface of the body 21 protrudes upward relative to the inner bottom surface of the body 21. A buoy 5 is provided on the recess 24, and a detection element 6 is provided inside the protrusion 12. The detection element 6 can detect the height of the buoy 5. A frame is provided on the top surface of the recess 24, and the buoy 5 is confined within the frame. When the water level in the body 21 is high, the buoy 5 is always located at a higher position within the frame. When the water level in the body 21 is low, the buoy 5 follows the water level at the same height. When the water level in the body 21 is lower than the recess 24, the buoy 5 will fall onto the recess 24.

[0056] Optionally, a magnetic element is installed on the float 5, and a Hall element is selected as the detection element 6. When the water level in the main body 21 is low, the user uses water to brew coffee, and the water in the main body 21 gradually decreases. The height of the float 5 drops accordingly. The detection element 6 detects the change in magnetic flux and determines the current water level. It can then send feedback to the alarm circuit inside the coffee machine to remind the user to add water. The low water level alarm circuit inside the coffee machine is well known to those skilled in the art, and its technical details will not be disclosed here.

[0057] In other alternatives, a transparent viewing window can be provided on the side wall of the main body 21 to allow users to observe the water level inside the main body 21 at any time.

[0058] In some embodiments, the water tank assembly further includes a heating device 7 and a water pipe 8. A water outlet valve 25 is provided at the bottom of the main body 21. The main body of the water pipe 8 is disposed inside the water tank seat 1. When the water tank 2 is assembled on the water tank seat 1, the water outlet valve 25 is opened, and the water inlet end of the water pipe 8 is connected to the interior of the main body 21. Water in the main body 21 can flow into the water pipe 8 from the water outlet valve 25. The water outlet end of the water pipe 8 extends out of the water tank seat 1 and is connected to the heating device 7. Water in the water pipe 8 can flow into the interior of the heating device 7 and be heated. Specifically, the water outlet end of the water pipe 8 is connected to a water pump 9. The water outlet end of the water pump 9 is connected to the heating device 7. The water pump 9 draws water out of the main body 21, passes through the water pipe 8, and delivers it to the heating device 7.

[0059] The outlet valve 25 can be made of commonly used components in existing technologies, which will not be listed here.

[0060] The heating element 7 is assembled inside the coffee machine housing. The coffee machine is equipped with a brewing module that can receive water from the outlet of the heating element 7. The water volume, water temperature, and water flow rate can be set. The heating element 7 has a water pipe section 71 and heating sections 72 located on both sides of the water pipe section 71. The water pipe section 71 is connected to the outlet of the water pipe 8. When the heating section 72 is powered, it can generate heat to heat the water in the water pipe section 71. The outlet of the water pipe section 71 is equipped with a temperature sensor 73 for detecting the water temperature. The temperature sensor 73 can accurately detect the water temperature. The user can control the water temperature according to the type of coffee being brewed so that the coffee liquid formed by brewing coffee powder has both flavor and aroma. A fuse 74 for overheat protection is located on the outer side of the middle part of the water pipe section 71. If the temperature of the water pipe section 71 is too high, the fuse inside the fuse 74 will blow, causing the heating section 72 to break the circuit and protect other components inside the coffee machine in time to prevent malfunctions due to high temperature.

[0061] The brewing module of a coffee machine can be set with water volume, water temperature, and water flow rate. The specific implementation method can be designed using common methods in existing technologies, and its technical details will not be described in detail here.

[0062] The fuse 74 can be any of the commonly used devices in the prior art, which will not be listed here.

[0063] The heating element 7 is an integral structure made of metal, which can reduce heat loss during the heat transfer process. The heating element 7 can be manufactured using common processes in the existing technology. When the heating part 72 of the heating element 7 is powered on, it can generate heat, which can be quickly transferred to the water pipe part 71 to heat the water in the water pipe part 71.

[0064] In a second aspect, this application also proposes a coffee machine, including a water tank assembly as described in the first aspect. The coffee machine of this application sets the ratio of the mating length of its water tank 2 and water tank base 1 at the mating position to the height of the water tank 2 or the height of the water tank base 1, so that the water tank 2 does not need to be locked and can be prevented from being easily touched and tipped over, so that the user can enjoy using the coffee machine to brew coffee.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
