Description

Technical Field

[0001] The present application relates to the technical field of coffee machines, and in particular to a brewing head for a coffee machine and a coffee machine. Background Art

[0002] The brewing head of a coffee machine usually needs to be screwed together with a handle to extract coffee. The existing brewing heads of coffee machines can be divided into two types according to the brewing head bracket: 1. An integrated bracket. 2. The bracket includes an outer frame and an inner frame of injection molding material.

[0003] The integrated bracket is generally made of two materials: stainless steel and aluminum alloy. The cost of the stainless steel bracket is higher than that of the aluminum alloy bracket, and the thermal conductivity of stainless steel is lower. Although the thermal conductivity of the integrated aluminum alloy bracket brewing head is higher, when extracting coffee, the handle needs to be screwed into the brewing head and has an interference fit with the brewing head bracket. When the handle and the brewing head rotate relative to each other, the aluminum alloy brewing head bracket is easily worn, resulting in severe wear of the brewing head and a short life.

[0004] In the brewing head whose bracket includes an outer frame and an inner frame of injection molding material, the inner frame of injection molding material can be used in conjunction with a metal outer frame, but this brewing head has no heat preservation effect. As we all know, in order to extract a cup of coffee with a rich taste and overflowing aroma, a stable extraction pressure and a constant water temperature are required. When water of a specified temperature flows into the brewing head of the coffee machine, the hot water encounters the brewing head bracket with a lower temperature. The brewing head bracket easily absorbs the heat of the water, resulting in the temperature of the water not reaching the specified temperature when extracting coffee, and causing poor consistency in the extraction water temperature when extracting coffee multiple times, which has a great impact on extracting ideal coffee.

[0027] The present application provides a coffee machine, which includes a brewing head. In addition, in one embodiment, the coffee machine may also include components such as a water tank, a heating chamber, and a water pump. When the coffee machine is turned on, the water in the water tank can be pumped into the heating chamber by the water pump and heated to the extraction temperature in the heating chamber. The brewing head is connected to the liquid path of the heating chamber, and the heated hot water can be used to extract coffee in the brewing head, and finally the coffee is discharged from the brewing head for the user to use. Among them, the brewing head can have the same or similar structure as the brewing head of any of the following embodiments, and achieve the same or similar functions.

[0028] like Figure 1-6 As shown, the present application also provides a brewing head for a coffee machine (hereinafter referred to as a brewing head). The brewing head includes a bracket 10, an abutment member 20 and a heating assembly 30. Figure 4 and Figure 5 As shown, the coffee machine may further include a handle 40 and a powder bowl 50. The powder bowl 50 is installed in the handle 40, and coffee powder cakes may be placed in the powder bowl 50. The handle 40 is installed on the bracket 10, and hot water may flow into the powder bowl 50, thereby extracting the coffee powder cakes in the powder bowl 50 into coffee, and finally the coffee flows out from the bottom of the handle 40 for the user to use.

[0029] The bracket 10 includes an outer frame 15 and an inner seat 16 connected to each other. The inner seat 16 is disposed inside the outer frame 15. The inner seat 16 and the outer frame 15 enclose a handle mounting cavity 13. In one embodiment, the outer frame 15 and the inner seat 16 can be integrally formed to eliminate the assembly process of the outer frame 15 and the inner seat 16. In another embodiment, the outer frame 15 and the inner seat 16 can also be two separate parts connected together.

[0030] A water flow channel 11 is provided in the inner seat 16. The water flow channel 11 has a water inlet end and a water outlet end. The water inlet end is used for hot water in the heating chamber to flow into the water flow channel. The water outlet end is connected to the handle installation cavity 13 so that the water in the water flow channel can flow out of the water flow channel 11 from the water outlet end and then flow into the handle 40 installed in the handle installation cavity 13.

[0031] Specifically, in one embodiment, Figure 4 As shown, the handle 40 has a handle body 41 and a protrusion 42. The handle body 41 has a receiving cavity 411, and the receiving cavity 411 is used to install the powder bowl 50. One end of the receiving cavity 411 has an installation opening 4111, and the installation opening 4111 is used to supply hot water to flow into the receiving cavity 411. The protrusion 42 is arranged on the annular side wall of the handle body 41, and the protrusion 42 is arranged at a position close to the installation opening 4111. The number of the protrusions 42 can be two, and the two protrusions 42 can be symmetrically distributed in the circumferential direction of the annular side wall.

[0032] Furthermore, if Figure 2As shown, in one embodiment, the outer frame 15 includes an annular side wall 151 and a bottom wall 152 connected to each other, and the inner seat 16 is arranged inside the annular side wall 151. The annular side wall 151, the bottom wall 152 and the inner seat 16 cooperate to form a handle installation cavity 13. An opening 131 is provided on the bottom wall 152, and the opening 131 can be used for one end of the handle 40 having the installation opening 4111 to enter and exit the handle installation cavity 13.

[0033] The inner seat 16 includes a recessed portion 14, which is formed by a recessed portion 14 on one side of the inner seat 16 facing the handle mounting cavity 13. A water flow channel 11 is provided in the recessed portion 14. Figure 5 As shown, the diameter of the opening 131 can be slightly larger than the diameter of the mounting opening 4111 of the handle 40, and the outer diameter of the recess 14 can be slightly smaller than the diameter of the mounting opening 4111, so that the mounting opening 4111 of the handle 40 can be sleeved on the outer periphery of the recess 14 through the opening 131, so that the handle 40 can receive the hot water flowing out of the recess 14.

[0034] The brewing head further includes an elastic member 60, which is sleeved on the outer periphery of the recessed portion, that is, the elastic member 60 may be annular in shape. The elastic member 60 may be made of an elastic material, such as a silicone material. The elastic member 60 has a first abutting surface 61 on one side facing the opening 131.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment, the abutment member 20 has a mounting portion 21, which is disposed on the bottom wall 152 of the outer frame 15, and is arranged around the contour of the opening 131. The mounting portion 21 is disposed opposite to the elastic member 60, and the mounting portion 21 has a second abutment surface 211 on the side facing the first abutment surface 61. When the handle 40 is installed in the handle installation cavity 13, the first abutment surface 61 and the second abutment surface 211 are used to limit the end of the handle 40 close to the installation opening 4111 (such as Figure 5 As shown), the end of the handle 40 close to the installation opening 4111 can be interference fit with the elastic member 60.

[0036] When in use, the protrusion 42 of the handle 40 is first misaligned with the mounting portion 21, so that the handle 40 can enter the handle mounting cavity 13 through the opening 131, and the end surface of the handle 40 close to the mounting opening 4111 abuts against the first abutting surface 61. Then the handle 40 is rotated along the axis of the handle 40 until the protrusion 42 of the handle 40 abuts against the second abutting surface 211 of the mounting portion 21. At this time, the end of the handle 40 close to the mounting opening 4111 is interference-fitted with the first abutting surface 61, so that the handle 40 can be fixed in the handle mounting cavity 13. When the handle 40 needs to be removed, it only needs to continue to rotate the handle 40 so that the protrusion 42 of the handle 40 is misaligned with the mounting portion 21, and the handle 40 can be taken out of the handle mounting cavity 13.

[0037] In order to facilitate the interference fit between the handle 40 and the elastic member 60, as shown in FIG. Figure 3 As shown, the second abutting surface 211 of the mounting portion 21 can be an inclined surface. The protrusion 42 can rotate along the inclined surface from the lower position to the higher position of the inclined surface. The closer the protrusion 42 is to the higher position of the inclined surface, the greater the interference fit between the handle 40 and the elastic member 60.

[0038] In some embodiments, the number of the abutment members 20 is at least two, and preferably, the number of the abutment members 20 is the same as the number of the protrusions 42 of the handle 40, and the distribution in the circumferential direction is the same, so that the abutment members 20 and the protrusions 42 can abut one-to-one. For example, the abutment members 20 can be evenly distributed in the handle mounting cavity 13 in the circumferential direction.

[0039] like Figure 1 As shown, the heating component 30 is thermally connected to the outer frame, and / or the heating component 30 is thermally connected to the inner seat. The outer frame 15 and / or the inner seat 16 are made of thermally conductive material. When the outer frame 15 and the inner seat 16 are integrally formed, both the outer frame 15 and the inner seat 16 are made of thermally conductive material. When the outer frame 15 and the inner seat 16 are two separate components, at least one of the outer frame 15 and the inner seat 16 needs to be made of thermally conductive material, and the thermally conductive material can be, for example, a material with high thermal conductivity such as metal or alloy, for example, aluminum alloy.

[0040] For example, in one embodiment, the outer frame 15 and the inner seat 16 of the bracket 10 can be two parts, and only the inner seat 16 can be configured as an aluminum alloy inner seat 16, so that the thermal conductivity of the inner seat 16 is higher, and the material of the outer frame 15 of the bracket 10 is not limited, for example, it can be configured as a plastic material, thereby reducing the cost of the bracket 10. In some embodiments, the outer frame 15 of the bracket 10 can also be configured as a metal material such as aluminum or stainless steel, and it is heated and heat-conducted by the heat conducting plate 33, so as to achieve the effect of keeping the liquid flowing therein warm.

[0041] The outer frame 15 and / or the inner seat 16 are thermally connected to the heating assembly 30 , wherein the thermally conductive connection means that the heat generated by the heating assembly 30 can be transferred to the outer frame 15 and / or the inner seat 16 to heat the outer frame 15 and / or the inner seat 16 .

[0042] Some existing brewing heads are made of one-piece stainless steel or aluminum alloy. One-piece stainless steel has high cost. Although one-piece aluminum alloy has high thermal conductivity, the brewing head needs to be directly in contact with the handle. The hardness of one-piece aluminum alloy is relatively low, which leads to wear and damage of one-piece aluminum alloy. Other existing brewing heads are formed by an inner frame of injection molding material and a metal bracket, but this type of brewing head has no heat preservation effect, and the metal bracket is just for appearance.

[0043] In the present application, on the one hand, the brewing head is provided with an abutment 20 in the bracket 10, and the abutment 20 can replace the bracket 10 to abut against the handle 40. When the handle 40 is screwed with the abutment 20, the handle 40 will wear the abutment 20 instead of directly wearing the bracket 10, thereby avoiding the problem that the handle 40 directly wears the bracket 10 and causes a shorter service life of the brewing head. On the other hand, the brewing head is provided with a heating component 30, and the outer frame 15 and / or the inner seat 16 are set as a heat-conducting material. When the heating component 30 heats the outer frame 15, the outer frame 15 can preheat the air in the handle installation cavity 13 to prevent the air from absorbing the heat of the extracted water in the handle 40; when the heating component 30 heats the inner seat 16, the temperature of the inner seat 16 is relatively high. When water flows through the water flow channel of the inner seat, the heat will not be absorbed by the inner seat 16 in large quantities, thereby achieving the effect of keeping the extracted water temperature warm. In this solution, the abutment 20 and the bracket 10 are two separate components. The abutment 20 can be set to a wear-resistant material, and the bracket 10 can be set to a material with high thermal conductivity as needed, which not only solves the problem of wear and insulation, but also solves the problem of heat preservation and can reduce costs.

[0044] In some embodiments, when the coffee machine is powered on and not in sleep mode, the heating component 30 continues to heat the bracket 10. At the same time, a sensor (not shown) is provided on the bracket 10 to monitor the temperature of the bracket 10 to ensure that the temperature of the bracket 10 is maintained at an appropriate temperature value.

[0045] In one embodiment, if Figure 1 and Figure 2As shown, the heating assembly 30 includes a heating element 32 and a heat conducting plate 33. The heat conducting plate 33 is mounted on the bracket 10, and the heat conducting plate 33 can be thermally connected to the outer frame 15 and / or the inner seat 16. The heating element 32 can be, for example, a heating strip. The heat conducting plate 33 is used to conduct the heat generated by the heating element 32 to the bracket 10. Since the contact area between the heating element 32 and the bracket 10 is limited, the heat transfer efficiency is low, which will cause the heat distribution of the bracket 10 to be uneven and the heat transfer efficiency to be low. By providing the heat conducting plate 33, the heat conducting plate 33 can evenly conduct the heat to the bracket 10, thereby improving the heat transfer efficiency of the bracket 10, so that the heat distribution on the surface of the bracket 10 is even and the heat transfer efficiency is high. It can be understood that in some embodiments, the heating element 32 can also be directly mounted on the outer frame 15 and / or the inner seat 16. In some embodiments, the heat conducting plate 33, the outer frame 15 and the inner seat 16 can be an integrally formed structure.

[0046] Since the inner seat 16 of the bracket 10 is provided with a water flow channel 11, when hot water flows slowly in the water flow channel 11, water tends to gather near the water inlet end of the water flow channel 11, and the inner seat 16 tends to absorb heat. Based on this, the heat conducting plate 33 can be attached to the side of the inner seat 16 away from the handle mounting cavity 13, and the heating element 32 can be attached to the side of the heat conducting plate 33 away from the inner seat 16. Therefore, the heat conducting plate 33 can mainly heat the inner seat 16 on the water inlet end side of the water flow channel 11.

[0047] In one embodiment, the brewing head further includes a heating strip pressing plate 70, one end of the heating strip pressing plate 70 is connected to the bracket 10, and the other end of the heating strip pressing plate 70 is pressed against the surface of the heating element 32 so that the heating element 32 is pressed tightly between the heating strip pressing plate 70 and the heat conducting plate 33.

[0048] In one embodiment, the brewing head further includes a connecting member (not shown), one end of which is connected to the heating assembly 30, and the other end of which is disposed in the handle mounting cavity 13 and connected to the abutment member 20. The connecting member is used to fix the heating assembly 30 and the abutment member 20 on the inner seat 16. Since both the abutment member 20 and the heating assembly 30 need to be fixed to the bracket 10, by connecting the abutment member 20 and the heating assembly 30 together, the assembly features (assembly holes, etc.) on the bracket 10 can be reduced, which is conducive to simplifying the assembly of the brewing head.

[0049] like Figure 2 and Figure 3 As shown, the abutment member 20 also has a connecting portion 212, which is connected to the mounting portion 21, wherein the connecting portion 212 is mainly used to connect and fix the abutment member 20. The connecting portion 212 can be arranged on the annular side wall 151 for connecting with the bracket 10.

[0050] In one embodiment, if Figure 6 As shown, Figure 6 for Figure 1 A schematic structural diagram of a brewing head for a coffee machine without a heating component 30 and a brewing head pressing piece 80.

[0051] like Figure 6 As shown, when the outer frame 15 and the inner seat 16 are integrally formed, in order to ensure successful demolding, an opening 161 is provided on the inner seat 16 to ensure smooth demolding. In some embodiments, the brewing head further comprises a brewing head pressing sheet 80, and the brewing head pressing sheet 80 is covered at the opening 161 to block the opening 161. Since the heating assembly 30 may need to be coated with thermal conductive silicone grease for heat conduction, the brewing head pressing sheet 80 covers the opening 161 to prevent the thermal conductive silicone grease from being squeezed and flowing through the opening 161 to the handle mounting cavity 13.

[0052] like Figure 1 As shown, in some embodiments, the connector penetrates the brewing head pressing piece 80, so that the brewing head pressing piece 80, the heating component 30 and the connecting part 212 are all connected together through the connector. Since the brewing head pressing piece 80, the heating component 30 and the connecting part 212 all need to be fixed in the bracket 10, if the brewing head pressing piece 80, the heating component 30 and the connecting part 212 are connected to the bracket 10 respectively, not only more mounting holes need to be provided on the bracket 10, but also more installation steps will be required, resulting in low installation efficiency. In this embodiment, by connecting the brewing head pressing piece 80, the heating component 30 and the connecting part 212 together through the connector, the number of assembly holes can be reduced, the installation steps can be reduced, and the installation efficiency can be improved.

[0053] Specifically, the heating assembly 30 is provided with a first mounting hole 31, and further, the first mounting hole 31 can be provided on the heat conducting plate 33. The brewing head pressing plate 80 is provided with a second mounting hole 81, and the connecting portion 212 is provided with a third mounting hole 2121. The first mounting hole 31, the second mounting hole 81 and the third mounting hole 2121 are arranged opposite to each other, and the connecting member passes through the first mounting hole 31, the second mounting hole 81 and the third mounting hole 2121 to connect the heating assembly 30, the brewing head pressing plate 80 and the abutment member 20. Among them, the connecting member can be, for example, a screw, and the heating assembly 30, the brewing head pressing plate 80 and the abutment member 20 are connected together by the screw, the assembly process is simple, the assembly features are less, and the efficiency of the installation can be improved.

[0054] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
