Description

Technical Field

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

[0002] Automatic beverage machines, such as coffee machines, are equipped with a water tank. A water pump draws water from the tank and sends it to a heating element for heating. At the same time, a drive mechanism extends a water outlet above a coffee basket, from which water is dispensed. The hot water is then introduced into the filter cup of the coffee basket, allowing for even brewing of the coffee grounds. These coffee machines allow users to control multiple variables according to their personal preferences, such as water flow rate and speed, water temperature, vibration frequency and rotation speed of the coffee basket, etc., to more precisely control the flavor of the coffee and produce unique coffee with both taste and aroma.

[0003] However, the coffee machine mentioned above does not isolate water and electricity, and does not isolate the drive control circuit, water temperature, water speed and water volume control circuit and water circuit. If the water circuit inside the coffee machine housing leaks due to component aging, the leaked water may come into contact with these control circuits, causing leakage and posing a risk of electric shock to the user, or even endangering the user's personal safety.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] like Figures 1-7 As shown in the illustration, this application provides a beverage machine, including a housing assembly 1, a circuit module 2, and a water circuit module 3. The housing assembly 1 includes an inner frame 11 and an outer shell 12. The inner frame 11 is provided with a first space 111 and a second space 112, which are separated by a partition. The outer shell 12 surrounds the outer periphery of the inner frame 11 and encloses the first space 111 and the second space 112. The circuit module 2 is disposed in the first space 111, and the water circuit module 3 is disposed in the second space 112. The water circuit module 3 is capable of drawing water from the beverage machine's water tank 7 or water from an external water source.

[0043] The circuit module 2 is located in the first space 111, and the water circuit module 3 is located in the second space 112. The circuit module 2 and the water circuit module 3 can be electrically connected through the upper part of the partition. If the water circuit module 3 leaks due to component aging, the water will not enter the first space 111 through the partition, will not come into contact with the circuit module 2, and will not cause a short circuit. The leaked water will flow to the bottom of the second space 112 and seep from the connection between the outer shell 12 and the inner frame 11, informing the user. The user can then immediately turn off the power of the beverage machine and repair it, or send the beverage machine for repair.

[0044] Thus, the beverage machine of this application has divided the installation areas of the circuit module 2 and the water circuit module 3, realizing the isolation of the water circuit and the circuit control, so that users can safely use the beverage machine to produce their favorite beverage products.

[0045] The beverage machine described in this application can be a coffee machine, a soy milk machine, a juicer, or other machine capable of producing beverages.

[0046] This application can be used to brew coffee and soy milk; brewed coffee has both flavor and aroma, making it popular among many young people; while soy milk, as a healthy beverage to accompany breakfast, is rich in high-quality plant protein, vitamins (such as vitamin E and B vitamins), minerals (calcium, magnesium, iron, etc.), and dietary fiber, which helps to enhance immunity and is loved by the elderly; when producing beverages such as coffee or soy milk, this application requires hot water to brew the coffee powder or soy milk powder. For this purpose, the water circuit module 3 can heat the water it draws. After the water is heated to a certain temperature, it can flow out from the water outlet window on the outer shell 12 for brewing coffee powder and soy milk powder.

[0047] The first space 111 and the second space 112 are adjacent. The circuit module 2 and the water circuit module 3 are separated only by a partition, and the thickness of the partition is generally not very thick. When the water circuit module 3 heats water, the heat generated will be transferred to the first space 111 through the partition, causing the temperature of the circuit module 2 to rise. The circuit module 2 will also generate heat when it is working. The accumulation of heat will cause the circuit module 2 to overheat or even burn out.

[0048] To avoid this situation, a mounting part 114a is formed on the partition. The circuit module 2 has a circuit board 21, on which the water temperature, water volume and water speed control circuit of the water circuit module 3 is integrated. The opposite ends of the circuit board 21 are respectively locked and fixed to the mounting part 114a, so that the circuit board 21 and any wall of the first space 111 formed by the inner frame 11 are left with gaps. Although the heat generated when the water circuit module 3 heats water will be transferred to the partition or other walls of the first space 111, only a very small amount of heat will be transferred to the circuit board 21. That is, when the water circuit module 3 heats water, it will not cause the circuit board 21 to be too hot, so as to ensure that the circuit module 2 can work normally for a long time.

[0049] In some embodiments, the inner frame 11 has a middle partition 114, a top partition 115, a bottom partition 116, and two side partitions 117. Here, the middle partition 114 is the partition mentioned above. The top partition 115 is connected to the top of the middle partition 114, the bottom partition 116 is connected to the bottom of the middle partition 114, and the two side partitions 117 surround the opposite sides of the top partition 115 and the bottom partition 116. The middle partition 114, the top partition 115, the bottom partition 116, and the two side partitions 117 enclose a first space 111 and a second space 112, and the first space 111 and the second space 112 are arranged opposite to each other. The circuit module 2 and the water channel module 3 can be well separated by the middle partition 114, the two side partitions 117, the top partition 115, and the bottom partition 116.

[0050] The beverage machine of this application also includes a water dispensing module 4, which has a water dispensing device 41 and a drive mechanism 42; the inner frame 11 is also provided with a third space 113, which is distributed on the top of the inner frame 11; the water dispensing device 41 is disposed in the third space 113, the water outlet end of the water circuit module 3 is connected to the water dispensing device 41, the main body of the drive mechanism 42 is disposed in the first space 111 and electrically connected to the circuit module 2, the drive end of the drive mechanism 42 is connected to the third space 113 and is connected to the water dispensing device 41 for transmission, and a window is provided on the outer shell 12 corresponding to the position of the water dispensing device 41. The drive mechanism 42 can drive the water dispensing device 41 to extend out of the third space 113 from this window, that is, to extend out of the outer shell 12 to dispense water, or drive the water dispensing device 41 to retract into the third space 113.

[0051] The inner frame 11 also includes a fence panel 118 and a rear panel 119. The fence panel 118 surrounds one side of the top partition 115 and connects to the two side partitions 117. The rear panel 119 surrounds the other side of the top partition 115 and connects to the two side partitions 117. The top partition 115, the side partitions 117, the fence panel 118, and the rear panel 119 together form a third space 113. The water channel module 3 can deliver water to the water outlet device 41 in the third space 113. The drive mechanism 42 of the water outlet module 4 is in the first space 111. If water leaks in the third space 113, it will not flow into the first space 111, will not come into contact with the drive mechanism 42 and the circuit module 2, and will not cause a short circuit.

[0052] As a preferred embodiment, the drive mechanism 42 of the water outlet module 4 includes a lead screw and nut drive mechanism, a cylinder, a linear motor, a gear and rack drive mechanism, etc. It can be set up with a structure commonly used in the prior art to drive the water outlet device 41 to move, extending out of the outer shell 12 or retracting into the third space 113.

[0053] In some embodiments, the inner frame 11 is an integral structure formed by injection molding, or the inner frame 11 is assembled by splicing and sealed at the splicing position. The inner frame 11 has openings for the electrical components of the water circuit module 3, and the openings are located above these components. The circuit module 2 is electrically connected to these components through these openings.

[0054] In some embodiments, the water circuit module 3 includes a water pump 31 and a heating device 32. The inlet of the water pump 31 is connected to the water tank 7 of the beverage machine or an external water source, and the outlet of the water pump 31 is connected to the heating device 32. The outlet of the heating device 32 is connected to the water outlet device 41. The water pump 31 can draw water from the water tank 7 of the beverage machine or water from an external water source and drive the water into the heating device 32 for heating. Under the drive of the water pump 31, water is transported from the heating device 32 to the water outlet device 41. Before this, the drive mechanism 42 can drive the water outlet device 41 from a third... The space 113 extends outward to the outside of the outer shell 12. A support platform 122 is provided on the outer shell 12 to hold a container or coffee basket 20. The coffee basket 20 is used to hold filter paper and coffee powder when brewing coffee. The water outlet of the water outlet device 41 is above the container or coffee basket 20. When water enters the water outlet container, the water will flow out from the water outlet of the water outlet device 41 under its own gravity and the drive of the water pump 31, and fall into the container or coffee basket 20. Hot water soaks the coffee powder to form coffee liquid, and the coffee liquid can flow out from the bottom of the coffee basket 20 into the beverage pot 10 of the beverage machine.

[0055] The heating element 32 is fixed on the intermediate partition 114. The heating element 32 has a water pipe section and heating sections on both sides of the water pipe section. The water inlet end of the water pipe section is connected to the water outlet end of the water pump 31, and the water outlet end of the water pipe section is connected to the water inlet end of the water outlet device 41. The top of the heating section extends upward into the first space 111 through an electric wire and is electrically connected to the circuit board 21 of the circuit module 2. The top of the water pump 31 also extends upward into the first space 111 through an electric wire and is electrically connected to the circuit board 21 of the circuit module 2. If water leaks at the connection between the water pipe section and the water outlet end of the water pump 31 or at the water inlet end of the water pump 31, the water will flow downward under the force of gravity and will not come into contact with the circuit interface between the heating element 32 and the circuit module 2, nor with the circuit interface between the water pump 31 and the circuit module 2, so that a short circuit will not occur.

[0056] The circuit board 21 integrates a coffee brewing circuit, and users can set the water volume, water temperature, and water flow rate.

[0057] The water circuit module 3 also includes a temperature sensor. The main body of the temperature sensor is located on the outer side of the top of the water pipe section. The main body of the temperature sensor is electrically connected to the circuit module 2 via a wire. The detection end of the temperature sensor extends into the water outlet of the water pipe section to detect the water temperature at the water outlet. Users 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 for overheat protection is installed on the outer side of the middle part of the water pipe section. If the temperature of the water pipe section is too high, the fuse inside the fuse will blow, causing the heating part to break the circuit, so as to protect other components inside the second space 112 in time to prevent failure due to high temperature.

[0058] In fact, the water outlet of the water pipe is connected to the inlet of the water outlet device 41 and the detection end of the temperature sensor through a three-way fitting. Specifically, the three-way fitting has a first end, a second end and a third end. The first end is connected to the water outlet of the water pipe, the second end is connected to the inlet of the water outlet device 41 through a deformable water pipe, and the detection end of the temperature sensor is connected to the inside of the three-way fitting through the third end. Furthermore, the wire used by the temperature sensor to connect its detection end and the third end form a seal to prevent water leakage.

[0059] Optionally, the heating element 32 is an integral structure made of metal, which can reduce heat loss during the heat transfer process. The heating element 32 can be manufactured using common processes in the prior art, so that the heating part of the heating element 32 can generate heat when energized, and the heat can be quickly transferred to the water pipe to heat the water in the water pipe.

[0060] Generally, condensation will form on the inner wall of the water outlet device 41, and when the water outlet device 41 is forced to remain inside the third space 113, the condensation will drip from the outlet of the water outlet device 41 into the third space 113, accumulate in the third space 113, and may even enter the second space 112 through the gap.

[0061] If necessary, the condensate dripping from the water outlet should be collected to prevent other problems such as bacterial growth or odor.

[0062] A wastewater collection pipe 5 can be installed in the third space 113. The wastewater collection pipe 5 is set with the outlet of the water outlet device 41. The portion of the outer shell 12 surrounding the second space 112 is provided with a wastewater discharge hole 121. The wastewater discharge hole 121 connects the second space 112 and the outside. The wastewater collection pipe 5 is connected to the wastewater discharge hole 121 via a water pipe. The box assembly 1 also includes a base 6. The inner frame 11 and the outer shell 12 are both set on the base 6. The base 6 is detachably provided with a water receiving tank 61. The water receiving tank 61 is used to hold the water flowing out from the wastewater discharge hole 121.

[0063] In addition, a limiting protrusion 611 is provided inside the water receiving tank 61, and a grid plate 62 for receiving the beverage jug 10 is connected to the opening of the water receiving tank 61. The limiting protrusion 611 supports the bottom of the grid plate 62 so that the grid plate 62 and the inner bottom surface of the water receiving tank 61 have space for water to be filled.

[0064] The side wall of the water inlet 612 is inclined and connected directly below the wastewater discharge hole 121. The water flowing out of the wastewater discharge hole 121 flows into the water inlet 612 of the water tank 61 under the force of gravity. After the water tank 61 is full of water, the user can remove it from the base 6, go to the bathroom to empty the water and clean the water tank 61, and then reinstall the water tank 61 on the base 6.

[0065] like Figure 7-9 As shown, the beverage machine of this application also includes a water tank 7, which is detachably connected to the base 6. The water tank 7 and the outer casing 12 stand side by side on the base 6, and the water tank 7 can supply water to the water circuit module 3.

[0066] Specifically, a water tank seat 63 is formed on the base 6 for assembling the water tank 7. The water tank seat 63 has an anti-tipping part 631. The water tank 7 has a body 71. The top of the body 71 is provided with a water inlet 72. The bottom edge of the body 71 protrudes downward to form an assembly part 73. The inner peripheral side of the assembly part 73 and the outer peripheral side of the anti-tipping part 631 form an abutment. Furthermore, the ratio between the vertical mating length of the assembly part 73 and the anti-tipping part 631 and the height of the body 71 is 1 / 12-1 / 8, and / or the ratio between the vertical mating length of the anti-tipping part 631 and the assembly part 73 and the height of the water tank seat 63 is greater than or equal to 1 / 2.

[0067] The proportion of the mating length of the water tank 7 and the water tank base 63 at the mating position of the beverage machine to the height of the water tank 7 or the height of the water tank base 63 is set so that the water tank 7 does not need to be locked and the water tank 7 will not tip over when the user accidentally touches it during the user's habitual actions such as twisting or reaching out.

[0068] Any position on the outer periphery of the anti-tipping part 631 of the water tank base 63 forms an abutment fit with the assembly part 73. Alternatively, the outer periphery of the anti-tipping part 631 has multiple mating positions, which are distributed at intervals around the center of the anti-tipping part 631. The anti-tipping part 631 forms an abutment fit with the assembly part 73 at the mating positions. There are multiple forces between the water tank 7 and the water tank base 63. The water tank base 63 can support the water tank 7 to remain upright and not tip over when subjected to forces from various directions.

[0069] The outer diameter of the anti-tipping part 631 gradually decreases from bottom to top, while the inner diameter of the assembly part 73 gradually increases from top to bottom. This allows the user to quickly align the assembly part 73 with the anti-tipping part 631 and quickly assemble the body 71 of the water tank 7 onto the water tank base 63.

[0070] The outer peripheral surface of the anti-tipping part 631 is an inclined surface that is slightly inclined relative to the vertical direction.

[0071] A first oblique line is formed by any position on the outer peripheral surface of the anti-tipping part 631 intersecting with the vertical plane, and a second oblique line is formed by any position on the inner peripheral surface of the assembly part 73 intersecting with the vertical plane. The angle α formed between the first oblique line and the vertical direction is equal to the angle β formed between the second oblique line 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 631 and the inner peripheral surface of the assembly part 73 can fit well together, and the water tank 7 can be smoothly and quickly assembled on the water tank base 63.

[0072] This can be understood as follows: a vertical plane is used to cut off the anti-tipping part 631 and the assembly part 73. The cross-section of the anti-tipping part 631 and the vertical plane have an intersecting line, namely the first oblique line, which is on the outer peripheral surface of the anti-tipping part 631. Similarly, the cross-section of the assembly part 73 and the vertical plane have an intersecting line, namely the second oblique line, which is on the inner peripheral surface of the assembly part 73. Both the first oblique line and the second oblique line are inclined relative to the vertical direction, and the angles they make with the vertical direction represent the degree of inclination of the anti-tipping part 631 and the assembly part 73, respectively.

[0073] The water tank 7 also includes a water tank cover, which is used to seal the water inlet 72 to prevent dust and other pollutants from entering the interior of the water tank 7 and contaminating the inner wall of the water tank 7 and the water inside. The water tank cover is rotatably connected to an adapter, the other end of which is rotatably connected to the inside of the main body 71 at the water inlet 72. When the water tank cover is on the water inlet 72, the adapter is located inside the main body 71 and cannot be seen by the user. In this way, the main body 71 and the water tank cover make the appearance of the entire water tank 7 look unified and coordinated, and visually more beautiful.

[0074] As a preferred embodiment, the water tank base 63 also has a support portion 632 and a boss 633. The support portion 632 is located below the anti-tipping portion 631, and a step is formed between the support portion 632 and the anti-tipping portion 631. The bottom end of the mounting portion 73 abuts against the step surface. The vertical mating length between the anti-tipping portion 631 and the mounting portion 73 is 20mm to 40mm. The boss 633 is formed on the top surface of the anti-tipping portion 631, and a recess 74 is formed on the outer bottom surface of the body 71. The recess 74 and the boss 633 match, and the vertical mating length between the recess 74 and the boss 633 is at least 15mm. In this way, the assembly between the body 71 of the water tank 7 and the water tank base 63 is more secure and less prone to shaking.

[0075] The portion of the recess 74 within the body 71 protrudes relative to the inner bottom surface of the body 71. That is, the recess 74, formed by the inward indentation of the outer bottom surface of the body 71, protrudes upward relative to the inner bottom surface of the body 71. A buoy is provided on the recess 74, and a detection element is provided inside the protrusion 633. The detection element can detect the height of the buoy. A frame is provided on the top surface of the recess 74, and the buoy is confined within the frame. When the water level in the body 71 is high, the buoy is always located at a higher position within the frame. When the water level in the body 71 is low, the buoy follows the water level at the same height. When the water level in the body 71 is lower than the recess 74, the buoy will fall onto the recess 74.

[0076] Optionally, a magnetic element is installed on the buoy, and a Hall element is selected as the detection element. When the water level in the main body 71 is low, after water is used, the water in the main body 71 gradually decreases, and the height of the buoy drops accordingly. The detection element 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 beverage machine is well known to those skilled in the art, and its technical details will not be disclosed here.

[0077] In other alternatives, a transparent viewing window can be provided on the side wall of the main body 71 to allow users to observe the water level inside the water tank body 71 at any time.

[0078] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
