[0050] Please refer to Figures 1 to 5 , the present utility model provides a brewing cylinder and the brewing module and beverage processing device to which it is applied.

[0051] It can be understood that there is no restriction on the specific form of the beverage processing device. Taking the coffee beverage processing device as an example: In actual application, the beverage processing device can be directly set as a brewer, that is, a device that basically only serves the brewing function and can press and brew the existing coffee powder. Or, the beverage processing device can be set as a fully automatic or semi-automatic coffee machine. According to actual needs, the coffee machine further includes a grinding module. The grinding module can grind coffee beans to obtain coffee powder and then transfer the coffee powder to the brewing module for pressing and brewing.

[0052] Among them, the brewing module includes a brewing cylinder, two piston members, a driving mechanism, and a water supply assembly.

[0053] The brewing cylinder includes a cylinder body 100, and the cylinder body 100 is provided with a through channel. It can be understood that there is no restriction on the specific installation orientation of the brewing module in this design. However, for the convenience of understanding, in the following embodiments, it is described by taking the brewing cylinder being generally cylindrical and its channel extending generally in the vertical direction as an example. Among them, the channel has a first port and a second port arranged oppositely, and the first port can be vertically below the second port.

[0054] The two piston members can be a first piston member 300 and a second piston member respectively. The first piston member 300 can be a piston member extending into the channel from the first port; the second piston member can be a piston member extending into the channel from the second port.

[0055] Among them, one of the first piston member 300 and the second piston member can be fixed relative to the brewing cylinder, and the other can reciprocate along the channel. For example, the first piston member 300 extends into the channel from the first port, or is maintained flush with the first port, so that the bottom of the brewing cylinder is blocked by the first piston member 300. The second piston member can move out of the channel, so that the second port is opened, and coffee powder can be introduced into the channel through the second port; then the second piston member can extend into the channel from the second port and can move toward the first port, approaching the first piston member 300, to press the coffee powder into a cake, and finally realize the brewing and extraction of the cake.

[0056] Alternatively, both the first piston member 300 and the second piston member can be movably arranged relative to the brewing cylinder. For example, the first piston member 300 can extend into the channel from outside the channel through the first port and can move toward the second port; the second piston member can extend into the channel from outside the channel through the second port and can move toward the first port.

[0057] In order to realize the driving of the movement of the first piston member 300 and / or the second piston member, the brewing module further includes a driving mechanism, and correspondingly, it can be a first driving mechanism for driving the movement of the first piston member 300 and / or a second driving mechanism for driving the movement of the second piston member. The specific forms of the first driving mechanism and / or the second driving mechanism are not limited, and can be a linear cylinder or other drivers, or a combination of a linear cylinder, a motor and other drivers and a transmission component. Among them, the transmission component can be set as a reversing transmission component according to actual needs, such as a gear rack mechanism, a lead screw nut mechanism, etc.; it can also be set as a transmission component for speed regulation and position adjustment, such as a gear set.

[0058] After the first piston member 300 extends into the channel from the first port, the first port of the channel is covered, that is, together with the cylinder body 100, a brewing chamber 110 with a closed bottom is defined. When the first piston member 300 and the second piston member approach each other in the brewing chamber 110 and press the coffee powder received by the first piston member 300, a cake is obtained. Then the water supply component can supply, for example, hot water to the cake to realize the brewing and extraction of the cake.

[0059] In view of the above, the brewing cylinder in this design further includes a heating device. The heating device is arranged on the cylinder body 100 and is used to heat the brewing chamber 110 so that the brewing chamber 110 is maintained within a preset temperature range.

[0060] In the technical solution provided by the present utility model, the heating device acts in the brewing cylinder to maintain the temperature in the brewing chamber 110 within a preset temperature range, so that the brewing chamber 110 is always in a heat preservation state before brewing and extracting the powder cake, avoiding a large temperature difference with the hot water connected subsequently, which helps to ensure that the operation of brewing and extracting the powder cake subsequently basically meets the theory, and ultimately helps to ensure that the prepared beverage has a high quality.

[0061] It can be understood that the specific value of the preset temperature range can be set according to actual needs. For example, it can be a value range default set by the brewing module and / or the beverage preparation device before leaving the factory, a value range automatically determined by a preset program, a value range detected and calculated by relevant detection devices, a value range entered by the user based on, for example, a touch panel set on the beverage preparation device, etc.

[0062] The main purpose of the heating device is to achieve heat preservation of the brewing chamber 110 in the cylinder body 100, especially when no extraction operation is performed on the powder cake in the brewing chamber 110. Therefore, in actual application, the beverage preparation device and / or the brewing module have a working state and a non-working state. Among them, the working state can be any working mode that requires brewing and extracting the powder cake in the brewing cylinder, such as a conventional beverage preparation mode, a debugging mode of beverage preparation parameters, etc.; the non-working state is, for example, a standby mode, a shutdown mode, etc. Among them, for example, when it comes to continuously or intermittently performing multiple beverage preparation operations, the interval stage between adjacent two beverage preparation operations should also belong to the non-working state.

[0063] The heating device is generally applied in the non-working state, that is, when it is confirmed that the brewing module is in the non-working state, the heating device starts to operate and heats and keeps warm the brewing chamber 110. Of course, there are various ways to determine whether the brewing module is in the non-working state. For example, it is manually triggered and confirmed by the user based on the above input module such as a touch panel, automatically triggered and confirmed by a preset program associated with relevant modes, sensed and confirmed by relevant sensor devices, etc.

[0064] Of course, in addition to being applied in the non-working state, the heating device can also be applied in the working state. When applied in the working state, the purpose of the heating device to heat the brewing chamber 110 is not for heat preservation, but for, for example, preheating or auxiliary heating to improve the beverage preparation efficiency and the quality of the prepared beverage. Or when it is necessary to clean the brewing chamber 110, for example, scraping the inner cavity wall of the brewing chamber 110 through the first piston member 300 and / or the second piston member, flushing the brewing chamber 110 with hot water or normal temperature water, etc., the heating device can assist in heating the brewing chamber 110, which helps to soften or solidify the residues on the inner cavity wall of the brewing chamber 110 and helps to improve the cleaning effect.

[0065] When the heating device can be applied in both the non - working state and the working state, the heating intensity of the heating device in the non - working state can be set to be different from that in the working state. Specifically, for example, the heating intensity of the heating device in the non - working state can be set to be not greater than that in the working state. The heating intensity can be reflected by, for example, the heating temperature, the heating speed, the heating duration, etc.

[0066] Specifically, the beverage preparation device further includes a sensor device and a controller device. The sensor device is used to sense the working parameters of the brewing cylinder; the controller device is electrically connected to the heating device and the sensor device respectively, and controls the heating device to start running when the working parameters sensed by the sensor device meet the preset conditions.

[0067] The sensor device is specifically set differently according to different working parameters sensed in the brewing cylinder. For example, when the working parameter includes a temperature value, the sensor device can specifically be a temperature sensor. When the temperature sensor senses that the temperature in the brewing chamber 110 is lower than the preset temperature threshold, it can be confirmed that the brewing chamber 110 currently needs to be heated, meeting the preset conditions, and the controller device can control the heating device to start running. Or for example, when the working parameter includes a duration, such as the interval duration between two adjacent beverage preparation operations, the sensor device can specifically be a time relay. When the time relay senses that the interval duration between two adjacent beverage preparation operations is greater than the first preset time threshold, it can be confirmed that the brewing chamber 110 currently needs to be heated, meeting the preset conditions, and the controller device can control the heating device to start running to meet the preset conditions. Of course, conversely, when the interval duration reaches the second preset time threshold (the second preset time threshold is greater than the first preset time threshold), for example, when it can be basically determined that there is no need to continue the next beverage preparation operation in the subsequent long period, the controller device can control the heating device to stop running.

[0068] Of course, the heating device can also be associated and set with relevant modes through a preset program as described above. For example, when it is confirmed that the beverage preparation device is shut down, the controller device automatically controls the heating device to stop running; and / or when it is confirmed that the beverage preparation device is powered on, the controller device automatically controls the heating device to start running; and / or when the target time point is reached, the controller device automatically controls the heating device to start running; and / or when it is determined from the currently executed mode that the next associated mode belongs to the working state, the controller device automatically controls the heating device to start running, etc.

[0069] In view of the above, there are multiple solutions for the heating device that can achieve the above - mentioned purpose:

[0070] In one embodiment, the heating device includes a heating resistance wire 210. The heating resistance wire 210 is used to generate heat when powered on. The power-on and power-off of the heating resistance wire 210 can be controlled and achieved by the power supply module inherent in the brewing module and / or the beverage processing device; or the power-on and power-off of the heating resistance wire 210 can be controlled and achieved by a specially provided power supply module.

[0071] In one embodiment, the heating device includes a heat exchange tube 220. The heat exchange tube 220 is used to circulate hot water and / or hot air. Sufficient heat is generated by the hot water and / or hot air circulating in the heat exchange tube 220, and then the heat is transferred into the brewing chamber 110 through the heat exchange tube 220.

[0072] In the above two embodiments, whether it is the heating resistance wire 210 or the heat exchange tube 220, the heating device shows a long-shaped structure. Therefore, when specifically arranged, in order to increase the heat exchange area with the inside of the brewing chamber 110, the heating device is wound around the periphery of the brewing chamber 110 in a spiral shape, that is, arranged in a spiral shape along the length direction and the circumferential direction of the brewing chamber 110. And / or, the heating device is arranged in multiple turns around the periphery of the brewing chamber 110. The multiple turns can be multiple turns arranged in sequence along the length direction of the brewing chamber 110, or multiple turns arranged in sequence along the width direction of the brewing chamber 110 (for example, the radial direction of the channel). And / or, the heating device is arranged in a grid pattern around the periphery of the brewing chamber 110. The grid pattern can be composed of multiple heating resistance wires 210 and / or heat exchange tubes 220 that extend in a long shape along the length direction of the brewing chamber 110 and are arranged in sequence along the circumferential direction of the brewing chamber 110.

[0073] In one embodiment, the heating device includes a heat storage bin 231, a connecting pipeline 232, and a pump body 233. Among them, the heat storage bin 231 is used to store hot water and / or hot air; the connecting pipeline 232 is connected to the heat storage bin 231 and the brewing chamber 110 in a switchable manner; the pump body 233 is arranged at the heat storage bin 231 or the connecting pipeline 232, and when the brewing module is switched to the non-working state, at the same time or afterwards, the hot water and / or hot air in the heat storage bin 231 is connected into the brewing chamber 110; and before the brewing module is switched to the working state, the hot water and / or hot air in the brewing chamber 110 is connected out to the heat storage bin 231.

[0074] It can be understood that the heat storage chamber 231 can be a structure independently used to provide hot water and / or hot air to the brewing chamber 110, or can be a structure directly using the inherent structure in the beverage processing device that can generate hot water and / or hot air, such as a hot water boiler system for brewing and extraction. The heat storage chamber 231 can directly store external hot water and / or hot air that meets the heat exchange requirements; or the heat storage chamber 231 can directly convert normal temperature liquid and / or gas into corresponding hot water and / or hot air that meets the heat exchange requirements through heating. Similarly, the connecting pipeline 232 can be a pipeline structure independently used to realize the circulation of hot water and / or hot air between the heat storage chamber 231 and the brewing chamber 110, or can be a pipeline structure directly using the inherent structure in the beverage processing device that can realize the circulation of hot water and / or hot air between the heat storage chamber 231 and the brewing chamber 110.

[0075] When it is determined that the brewing module has switched to the non-working state, or after that, that is, when the brewing chamber 110 needs to be heated, the pump body 233 is started and the hot water and / or hot air in the heat storage chamber 231 that meets the heat exchange requirements is connected into the brewing chamber 110 through the connecting pipeline 232; since the current hot water and / or hot air occupies the space of the brewing chamber 110, before it is determined that it is necessary to switch to the working state, the pump body 233 is started to connect the hot water and / or hot air in the brewing chamber 110 out of the brewing chamber 110 through the connecting pipeline 232, so as to vacate the space of the brewing chamber 110. The hot water and / or hot air realizes circulation between the heat storage chamber 231 and the brewing chamber 110.

[0076] Of course, based on any of the above embodiments, an installation cavity 130 is formed in the outer cylinder wall of the brewing chamber 110 of the cylinder body 100, and the cylinder wall separating and blocking between the installation cavity 130 and the brewing chamber 110 is the first cylinder wall 120, and at least the first cylinder wall 120 is made of a heat-conducting material; at least part of the heating device is arranged in the installation cavity 130. For example, a heating device set as a heating resistance wire 210 and / or a heat exchange tube 220 can be installed in the installation cavity 130. Compared with the scheme of directly installing in the brewing chamber 110, it can prevent the heating device from having an adverse effect on the normal brewing and extraction operation of the brewing cylinder. And since the first cylinder wall 120 or the cylinder body 100 as a whole is made of a heat-conducting material, the heat generated by the heating device in the installation cavity 130 can be more efficiently transferred into the brewing chamber 110 to achieve the purpose of heat preservation.

[0077] Of course, when the heating device includes the heat storage chamber 231, the connecting pipeline 232 and the pump body 233 as described above, the installation cavity 130 can also be selected to replace the brewing chamber 110 at this time, that is, under the action of the pump body 233, the circulation of hot water and / or hot air between the installation cavity 130 and the heat storage chamber 231 is realized. The hot water and / or hot air does not occupy the space in the brewing chamber 110.

[0078] In addition, based on the above, especially when the entire cylinder block 100 is made of a heat-conducting material, further, the brewing cylinder further includes a heat-insulating layer, which is at least provided on the side of the heating device facing away from the brewing chamber 110. The heat-conducting performance of the heat-insulating layer is inferior to that of the material of the cylinder block 100, so as to weaken the intensity of heat exchange between the cylinder block 100 and the external environment of the cylinder block 100. That is, it can avoid the loss of heating the brewing chamber 110 by the heating device, and further helps to improve the heating efficiency of the heating device for the brewing chamber 110.

[0079] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
