[0001] This utility model belongs to the field of small household appliance technology, and in particular relates to a coffee machine. Background Technology

[0002] Currently, ice drip coffee machines on the market can only be used to make cold coffee and cannot make hot coffee. For example, Chinese patent CN221242531U discloses a constant temperature ice drip coffee machine, which can only be used to make cold coffee. When users want to drink hot coffee, they need to use a separate coffee machine that can make hot coffee. Utility Model Content

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of this utility model embodiment is to provide a coffee machine. This coffee machine achieves the functional effects of an integrated cold and hot coffee machine.

[0004] The technical solution adopted in this embodiment of the utility model is:

[0005] A coffee machine, comprising:

[0006] The machine body has a box compartment and a cup compartment, the cup compartment being located below the box compartment and used to hold coffee cups;

[0007] A brewing box is detachably installed inside the compartment, and the brewing box can hold coffee powder or ice cubes;

[0008] A brewing head is provided on the machine body. When the brewing box is installed in the box compartment, the brewing head can be connected to the brewing box to drip the liquid in the brewing box into the coffee cup.

[0009] A cooling component and a hot water component are respectively disposed on the main body. The cooling component is used to cool the cup compartment. The hot water component includes at least a water tank, a water pump, a water inlet pipe, a heating element, and a hot water pipe. The water inlet of the water pump is connected to the water tank, and the water outlet of the water pump is connected to the hot water pipe through the heating element. The water pump is used to pump water from the water tank into the heating element for heating, and the heated water can be sent into the brewing chamber through the hot water pipe.

[0010] In some embodiments, the body has a compartment cover that can open or close the compartment, the compartment cover is provided with a water outlet, the hot water pipe is connected to the water outlet, and the hot water in the hot water pipe can flow into the brewing box through the water outlet.

[0011] In some embodiments, the center of the lid has a protruding water storage cavity, and the cavity wall of the water storage cavity is provided with multiple water outlets, forming the water outlet section. Hot water generated inside the heating element can be sprayed from the top of the coffee powder through the water outlet section for better brewing of the coffee powder.

[0012] In some embodiments, the hot water pipe is connected to the water storage chamber via a flexible hose, allowing hot water from the pipe to flow into the chamber. The hose can bend and deform when the chamber lid is open or closed. This ensures connection to the hot water pipe regardless of whether the chamber lid is open or closed, preventing water leakage.

[0013] In some embodiments, the hot water assembly further includes a flow meter disposed on the inlet pipe.

[0014] In some embodiments, the body includes a main support frame and an outer shell, the box compartment and the cup compartment are respectively disposed on the main support frame, the outer shell covers the main support frame, and a shell cavity is defined between the outer shell and the main support frame, and the refrigeration component and the hot water component are respectively disposed in the shell cavity.

[0015] In some embodiments, the main support has an air inlet and an air outlet communicating with the cup compartment;

[0016] The refrigeration assembly further includes a cooling element, a heat-conducting element, and a blower. The heat-conducting element is connected to the cooling element and is used to absorb the cooling capacity of the cooling element. The air inlet of the blower is opposite to the air outlet. The blower can draw air out of the cup compartment and blow it onto the heat-conducting element for cooling. The cooled air can then re-enter the cup compartment through the air inlet. This structure is simple and can ensure that a low-temperature environment is maintained inside the cup compartment.

[0017] In some embodiments, the refrigeration assembly further includes insulation cotton with a through-hole. The shape of the through-hole is adapted to the shape of the refrigeration component, and the refrigeration component is embedded in the through-hole. This insulation cotton can prevent the cold air from leaking out of the refrigeration component.

[0018] In some embodiments, the body further includes insulating foam located between the main support frame and the outer shell. The shape of the insulating foam is adapted to the shape of the outer shell and conforms to the inner wall of the outer shell. The insulating foam can insulate the cup compartment, thereby better maintaining the low-temperature environment inside the cup compartment.

[0019] In some embodiments, the brewing head includes a drip head and an adjustment knob. The drip head has a drip channel passing through its opposite ends. One end of the drip channel is used to communicate with the brewing chamber, and the other end is opposite to the mouth of the coffee cup.

[0020] The outer peripheral wall of the drip head has a knob channel communicating with the drip channel. The adjustment knob is screwed into the knob channel and extends into the drip channel. Rotating the adjustment knob can adjust the opening and closing degree of the drip channel. By rotating the adjustment knob, the dripping speed of melted water or coffee in the brewing chamber can be controlled.

[0021] Compared with the prior art, the beneficial effects of the embodiments of this utility model are as follows:

[0022] The coffee machine in this embodiment integrates a refrigerator, an ice drip coffee machine, and a hot coffee machine into one unit. It can be used to make ice drip coffee as well as hot coffee. It also has a cooling function for the ice storage cavity of the machine, so that coffee can be brewed in a low-temperature environment and can be drunk immediately after brewing, eliminating the need for refrigeration and thus shortening the user's waiting time.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly. To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0042] like Figures 1 to 3 As shown, this utility model embodiment provides a coffee machine, which mainly includes a body 1 and a brewing chamber 2, a brewing head 8, a cooling component 3 and a hot water component 4 respectively disposed on the body 1.

[0043] The machine body 1 has a box compartment 17 and a cup compartment 18. The cup compartment 18 is located below the box compartment 17 and is used to hold the coffee cup 7.

[0044] The brewing chamber 2 is detachably installed inside the chamber 17, and the brewing chamber 2 can hold at least coffee powder 21 or ice cubes 22. When the brewing chamber 2 is installed inside the chamber 17, the brewing head 8 can be connected to the brewing chamber 2 to drip the liquid in the brewing chamber 2 into the coffee cup 7.

[0045] For example, when ice cubes 22 are placed in the brewing tank 2, the melted ice water can drip into the coffee cup 7 below through the brewing head 8; when coffee powder 21 is placed in the brewing tank 2, hot water can be introduced into the brewing tank 2 to make hot coffee, and the hot coffee can drip into the coffee cup 7 below through the brewing head 8.

[0046] The cooling component 3 and the hot water component 4 are respectively installed on the body 1, such as Figure 2 and Figure 4 As shown, the cooling component 3 is used to cool the cup compartment 18, thereby lowering the temperature inside the cup compartment 18. When making iced drip coffee, the cup compartment 18 can be cooled to brew coffee in a low-temperature environment, allowing it to be drunk immediately after brewing, eliminating the need for refrigeration, thus shortening the user's waiting time and improving the user experience.

[0047] like Figure 2 and Figure 5As shown, the hot water assembly 4 includes at least a water tank 41, a water pump 42, an inlet pipe 43, a heating element 44, and a hot water pipe 45. The inlet end of the water pump 42 is connected to the water tank 41, and the outlet end of the water pump 42 is connected to the hot water pipe 45 through the heating element 44. The water pump 42 is used to pump water from the water tank 41 into the heating element 44 for heating to form hot water, and the heated hot water can be sent into the brewing tank 2 through the hot water pipe 45.

[0048] It is readily apparent that, when the coffee machine of this application needs to make iced drip coffee, ice cubes 22 can be placed in the brewing chamber 2, and then the cup compartment 18 is cooled during the iced drip coffee making process. (See...) Figure 4 As shown. When hot coffee is needed, coffee powder 21 can be placed in brewing chamber 2, and then hot water can be introduced into brewing chamber 2. At this time, the cooling component 3 does not need to be activated, and the cup compartment 18 can be kept at room temperature. See Figure 5 As shown.

[0049] The coffee machine in this embodiment integrates a refrigerator, an ice drip coffee machine, and a hot coffee machine into one unit. It can be used to make ice drip coffee and hot coffee. It also has a cooling function for the ice storage cavity of the machine body 1, so that coffee can be brewed in a low-temperature environment and can be drunk immediately after brewing, eliminating the need for refrigeration and thus shortening the user's waiting time.

[0050] In some embodiments, the container 17 may be located at the upper part of the body 1, and the cup compartment 18 may be located at the lower part of the body 1. The top of the body 1 has a cover 13 that can open or close the container 17, and when the cover 13 closes the container 17, it may be directly opposite the open end of the brewing tank 2. For example, the cover 13 may be rotatably connected to the body 1, and the cover 13 may rotate relative to the body 1 to open or close the container 17.

[0051] The lid 13 is provided with a water outlet 14. The hot water pipe 45 in the hot water assembly 4 can be connected to the water outlet 14. The hot water formed in the heating pipe 44 can be sprayed from the top of the coffee powder 21 through the water outlet 14 to better brew the coffee powder 21.

[0052] For example, such as Figure 3 As shown, the lid 13 has a protruding water storage cavity in the middle of the side opposite to the container 17, and the cavity wall of the water storage cavity has multiple water outlets 140. The water storage cavity can form a water outlet 14. When the lid 13 closes the container 17, hot water can be directly introduced into the water outlet 14 and then sprinkled onto the coffee powder 21 through the water outlets 140.

[0053] It should be noted that the connection between the water outlet 14 and the hot water pipe 45 in this embodiment can be in various ways. For example, the cover 13 can also be provided with a water inlet channel communicating with the water storage chamber. When the cover 13 is closed and the tank 17 is closed, the water inlet channel can be directly connected to the hot water pipe 45. At this time, the hot water assembly 4 can be activated to produce hot water, which can flow into the water storage chamber through the water inlet channel. When the cover 13 is opened and the tank 17 is opened, the water inlet channel is disconnected from the hot water pipe 45.

[0054] Alternatively, the hot water pipe 45 in the hot water assembly 4 can be directly connected to the water storage cavity on the cover 13 via a heat-resistant hose (not shown in the figure). During the process of closing or opening the compartment 17, the hot water pipe 45 is always connected to the water storage cavity via the heat-resistant hose. In this way, the connection between the cover 13 and the hot water pipe 45 can be achieved regardless of whether the compartment 13 is open or closed, thus preventing water leakage from the hot water pipe 45.

[0055] In some embodiments, the hot water assembly 4 may also include a flow meter 46 disposed on the inlet pipe 43, and the coffee machine may be provided with a control assembly 6, which includes a circuit board 61. The circuit board 61 is connected to the water pump 42 and the flow meter 46 respectively. The flow meter 46 can be used to monitor the amount of water that the water pump 42 can measure, and the circuit board 61 can control the start and stop of the water pump 42 according to the measured amount of water.

[0056] like Figure 3 As shown, in some embodiments, the brewing head 8 may include a dripping head 81, a connector 82, and an adjustment knob 84. The dripping head 81 may have a dripping channel (not shown in the figure) that runs through the upper and lower ends of the brewing head 8. The outer peripheral wall of the dripping head 81 may have a knob channel 85 that connects to the dripping channel.

[0057] The connector 82 can be located above the drip head 81 and is used to fix the drip head 81 to the body 1. The connector 82 can be equipped with a sealing ring 83, which can ensure that the blended water or coffee in the brewing tank 2 flows to the outside of the brewing head 8.

[0058] The adjusting knob 84 is screwed into the knob channel 85 and extends into the drip channel. By rotating the adjusting knob 84, the opening and closing degree of the drip channel can be adjusted, thereby adjusting the dripping speed of the water.

[0059] Furthermore, the bottom of the brewing tank 2 may have a liquid outlet that communicates with the upper end of the drip channel, through which the ice water or brewed coffee mixed in the brewing tank 2 flows into the drip channel of the brewing head 8.

[0060] like Figure 1 and Figure 2As shown, in some embodiments, the body 1 may include a main support 10 and an outer shell 11. The compartment 17 and the cup compartment 18 are respectively formed on the main support 10, and the outer shell 11 may completely or at least partially cover the main support 10.

[0061] The main body 1 may also include a door 15 for opening or closing the cup compartment 18, and the door 15 is closed when the cup compartment 18 needs to be cooled.

[0062] A cavity (not shown in the figure) can be defined between the outer shell 11 and the main support 10, and the cooling component 3 and the hot water component 4 are respectively disposed in the cavity.

[0063] The main body 1 may also include a bracket 47 for fixing the heating element 44. The bracket 47 can be directly fixed to the main body bracket 10, and the hot water pipe 45 can be directly fixed to the main body bracket 10.

[0064] The water tank 41 can be mounted on the main support 10, and the outer casing 11 can be provided with a water inlet communicating with the water tank 41, through which water can be added to the water tank 41. Alternatively, the water tank 41 can be detachably mounted on the main support 10, and the outer casing 11 can be provided with a water tank door. By opening the water tank door, the water tank 41 can be taken out and water can be added. After adding water, the water tank 41 can be reassembled on the main support 10, and then the water tank door can be closed.

[0065] In some embodiments, thermal insulation foam 12 may be provided between the outer shell 11 and the main support 10. The shape of the thermal insulation foam 12 is adapted to the shape of the outer shell 11 and is attached to the inner wall of the outer shell 11. The thermal insulation foam 12 can keep the cup compartment 18 warm, so as to better maintain the low temperature environment inside the cup compartment 18.

[0066] In some embodiments, the refrigeration assembly 3 may include a refrigeration element 31, a first heat-conducting element 32, and a blower 33.

[0067] The cooling component 31 can be a semiconductor cooling component 31, which can perform cooling after being powered on. The first heat-conducting component 32 can be connected to the cooling side of the cooling component 31 to achieve heat transfer. After the cooling component 31 cools down, the heat of the first heat-conducting component 32 also decreases due to the heat conduction effect.

[0068] The main support 10 of the body 1 can be provided with an air inlet 102 and an air outlet 101 that communicate with the cup compartment 18. The air inlet side of the blower 33 corresponds to the air outlet 101 on the main support 10, and the air outlet side of the blower 33 is opposite to the first heat conduction element 32. When the blower 33 is started, the blower 33 can draw the air from the cup compartment 18 through the air outlet 101 and blow it toward the first heat conduction element 32. After being cooled by the airflow through the first heat conduction element 32, it can be blown back into the air inlet 102 on the main support 10. This allows the cold air to flow in the cup compartment 18, thereby better cooling the cup compartment 18.

[0069] In some embodiments, the coffee machine may further include a heat dissipation assembly 5, which may include a cooling fan 51 and a second heat-conducting element 52. The cooling fan 51 may be opposite to the heat dissipation side of the cooling component 31, and the second heat-conducting element 52 is connected to the heat dissipation side of the cooling component 31 and located between the cooling fan 51 and the cooling component 31. The second heat-conducting element 52 absorbs the heat generated by the cooling component 31 during operation. During the operation of the cooling component 31, the cooling fan 51 can be activated to dissipate heat from the second heat-conducting element 52, ensuring that the cooling component 31 can operate for a long time. The first heat-conducting element 32 and the second heat-conducting element 52 may be made of materials with high thermal conductivity, such as aluminum plates or copper plates.

[0070] In some embodiments, the refrigeration component 3 may further include insulation cotton 34 for wrapping the refrigeration component 31. The insulation cotton 34 has a through-hole adapted to the shape of the refrigeration component 31. The refrigeration component 31 can be embedded in the through-hole. The insulation cotton 34 can prevent the cold air of the refrigeration component 31 from overflowing, thereby better maintaining its refrigeration effect.

[0071] For example, such as Figure 2 As shown, the cooling component 31 has opposing cooling and heat dissipation surfaces. The cooling surface can contact the first heat-conducting component 32 through the heat-conducting block 35, while the heat dissipation surface directly contacts the second heat-conducting component 52. The first heat-conducting component 32 and the second heat-conducting component 52 are also shown.

[0072] like Figure 3 As shown, in some embodiments, the control component 6 on the coffee machine may further include a control board 62, which may be provided with a power button 621, a hot coffee button 622, an iced coffee button 623, a room temperature button 624 and a cooling button 625, which are respectively connected to the circuit board 61 of the coffee machine.

[0073] For example, when you need to make iced coffee, press the power button 621 and the coffee machine will be in standby mode. Then press the iced coffee button 623, put the filter 9 into the rated coffee powder 21 and put it into the coffee cup 7, then put the coffee cup 7 into the cup compartment 18 and close the compartment door 15.

[0074] Next, open the chamber lid 13 on the machine body 1, put the rated ice cubes 22 into the brewing chamber 2, and then close the chamber lid 13. The ice water after the ice cubes 22 melt will drip through the brewing head 8 onto the filter screen 9 containing coffee powder 21, and finally drip into the coffee cup 7.

[0075] At this time, if the refrigerator needs to be cooled, the cooling button 625 can be pressed, and the coffee machine will start the cooling component 31 to cool the cup compartment 18.

[0076] When you need to make hot coffee, first add room temperature water to the water tank 41. After pressing the power button 621, press the hot coffee button 622. The machine will start the water pump 42 and draw a fixed amount of water from the water tank 41 into the heating element 44 for heating. When the target temperature is reached, the hot water will pass through the hot water pipe 45 and the water outlet 14 on the cover 13 to brew the coffee powder 21 in the brewing chamber 2. Finally, the coffee liquid will flow into the coffee cup 7 through the brewing head 8.

[0077] During this period, if the refrigerator does not need to cool, the normal temperature button 624 can be pressed, and the main unit will not start the cooling component 31.

[0078] In some embodiments, the body 1 may also include a water-absorbing pad 16 disposed in the shell cavity. The water-absorbing pad 16 can be used to wrap the cooling component 3. The water-absorbing pad 16 can not only absorb the liquid water generated by the cooling component 3, but also absorb the liquid water inside the body 1, so as to keep the body 1 in a relatively dry environment.

[0079] As for the structure of the absorbent pad 16, this application embodiment does not impose specific limitations, and it can be set according to the structure and layout of the entire cooling component 3.

[0080] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
