Description

Technical Field

[0001] This application relates to the field of heating technology for beverage makers, and in particular to heating devices and beverage making equipment. Background Technology

[0002] In recent years, beverage-making equipment such as coffee machines and self-service beverage machines have become increasingly common in various daily life and work settings. Consequently, consumers are placing higher demands on the performance of these devices. Furthermore, with the growing market, the increasing variety of beverages, and the need to meet customers' demands for different beverage serving temperatures, the heating devices in multi-functional beverage equipment require the ability to quickly and accurately control and adjust temperatures, as well as provide a continuous supply of hot water at various temperatures.

[0003] In existing technologies, hot water or steam is typically supplied to beverage equipment using boilers or electric heating plates. Boilers heat room temperature water to a set temperature before brewing or extracting the beverage, allowing for direct hot water dispensing during brewing or extraction. While this method offers strong continuous production capacity, it suffers from a delay in temperature feedback, making it unsuitable for brewing or extracting beverages at various temperatures. Electric heating plates, on the other hand, allow room temperature water to enter the heating plate before brewing or extraction, enabling real-time heating and controllable extraction temperature. However, this method has poor continuous production capacity and cannot accommodate continuous beverage production. Utility Model Content

Detailed Implementation

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] See Figure 1One embodiment of this application provides a beverage making device, including a heating device 100, a water injection assembly, pipelines, and a brewing assembly. The brewing assembly has a brewing chamber. A liquid such as water can be brewed or extracted within the brewing chamber to obtain a beverage.

[0032] Specifically, such as Figure 2 as well as Figure 3 As shown, the heating device 100 includes a heat storage heating assembly 110, an instant heating assembly 120, and a first liquid pipe 101. The heat storage heating assembly 110 is provided with a heating chamber 111 and a first heating element 112. The first heating element 112 is disposed in the heating chamber 111 and is used to heat the liquid in the heating chamber 111. A water injection assembly is connected to the heating chamber 111 and is used to connect a water source to the heating chamber 111. The water source can refer to municipal water or bottled water, etc.

[0033] like Figure 4 as well as Figure 5 As shown, the instant heating assembly 120 includes a heating channel 121 and a second heating element 122. The second heating element 122 is disposed in the heating channel 121 and is used to heat the liquid within the heating channel 121. The storage heating assembly 110 has a liquid inlet 1101 and a liquid outlet 1102. The instant heating assembly 120 has a liquid inlet 1201 and a liquid outlet 1202. The liquid outlet 1102 of the storage heating assembly is connected to the liquid inlet 1201 of the instant heating assembly via a first liquid pipe 101, and the liquid outlet 1202 of the instant heating assembly is connected to the brewing chamber via a pipe.

[0034] Understandably, the water injection assembly injects cold water into the heating chamber 111, where it is heated by the first heating element 112 and stored within the heating chamber 111. The heating chamber 111 is connected to the heating channel 121 via the first liquid pipe 101, allowing hot water from the heating chamber 111 to enter the heating channel 121 and then from the heating channel 121 into the brewing chamber of the brewing assembly. The heating chamber 111's ability to store hot water ensures the stability of the hot water flow rate during the extraction process, thereby improving the continuity of the hot water production process. This, in turn, enhances the compatibility between the hot water output flow rate and the flow rate requirements of the extraction process, optimizing the extraction effect.

[0035] Correspondingly, the cooperation of the heating channel 121 and the second heating element 122 enables the hot water in the heating chamber 111 to be reheated to form hot water at a higher temperature, thereby achieving precise and efficient temperature regulation, improving the accuracy of hot water production, avoiding insufficient continuous output capacity caused by the instantaneous heating component directly processing low-temperature water, and thus improving the adaptability of the hot water output temperature to the temperature requirements of the extraction process, and optimizing the extraction effect.

[0036] Furthermore, the heating cooperation between the heat storage heating component 110 and the instant heating component 120 reduces the temperature difference requirement that the second heating element 122 needs to overcome, and allows for further heating using the heat from the heating chamber 111, thereby improving heating efficiency.

[0037] In addition, in one example scenario, the temperature difference change of the liquid after heating in the heating chamber 111 is greater than the temperature difference change of the liquid in the heating channel 121. At this time, the first heating element 112 shares most of the basic heating load, while the instantaneous heating component only needs to supplement the temperature slightly, which reduces the instantaneous power requirement of the instantaneous heating component and helps to reduce losses.

[0038] It should be noted that the first heating element 112 in the above embodiments may be, but is not limited to, a metal resistance heating tube, a PTC ceramic heater, or an electromagnetic induction heating coil. Furthermore, the second heating element 122 in the above embodiments may be, but is not limited to, a metal resistance heating tube, an electric heating wire, or a thick-film heating element. No further restrictions are placed on the types of the first heating element 112 and the second heating element 122.

[0039] In some embodiments, such as Figures 1 to 5 As shown, the heating device 100 also includes a second liquid pipe 102, a third liquid pipe 103, a liquid outlet control valve 130, and a flow meter 140. The liquid outlet control valve 130 is connected to the liquid outlet 1202 of the instantaneous heating component via the second liquid pipe 102. Figure 3 as well as Figure 4 As shown, the inlet end 1401 of the flow meter 140 is connected to the outlet control valve 130 through the third liquid pipe 103, and the outlet end 1402 of the flow meter 140 is connected to the brewing chamber through a pipeline. The outlet control valve 130 is used to control the flow direction of the liquid in the second liquid pipe 102, and the flow meter 140 is used to measure the liquid entering the brewer.

[0040] Understandably, when the liquid outlet control valve 130 controls the flow of the second liquid pipe 102, the liquid material passing through the instant heating component 120 can pass through the second liquid pipe 102, sequentially through the liquid outlet control valve 130, the third liquid pipe 103, the inlet end 1401 of the flow meter 140, and the outlet end 1402 of the flow meter 140, and finally be connected to the brewing chamber through the pipeline. The flow meter 140 is designed to facilitate the control of the hot water output, thereby improving the compatibility between the hot water output and the water volume requirements of the required extraction mode, and optimizing the extraction effect.

[0041] In the above embodiments, the liquid discharge control valve 130 can be, but is not limited to, a solenoid valve, a switching valve, a throttle valve, etc., and no further restrictions are imposed here.

[0042] Furthermore, in one embodiment, see back Figure 1 as well as Figure 5 The liquid outlet control valve 130 includes an inlet end 1301, a first outlet end 1302, and a second outlet end 1303. A second liquid pipe 102 is connected between the liquid outlet of the instantaneous heating assembly 120 and the inlet end 1301 of the liquid outlet control valve 130. A third liquid pipe 103 is located between the first outlet end 1302 of the liquid outlet control valve 130 and the inlet end 1401 of the flow meter 140. The liquid outlet control valve 130 has a first open state and a second open state.

[0043] When the liquid discharge control valve 130 is in the first open state, the inlet end 1301 is connected to the first outlet end 1302. When the liquid discharge control valve 130 is in the second open state, the inlet end 1301 is connected to the second outlet end 1303.

[0044] It is understandable that when the liquid outlet control valve 130 is in the first open state, the inlet end 1301 is connected to the first outlet end 1302, and the water source, water injection component, heating chamber 111, first liquid pipe 101, heating flow channel 121 and brewing chamber are connected in sequence, which can produce hot water at a higher temperature and input it into the brewing chamber.

[0045] When the liquid outlet control valve 130 is in the second open state, the inlet end 1301 is connected to the second outlet end 1303.

[0046] Thus, by switching between the first and second open states of the liquid outlet control valve 130, the beverage preparation equipment can switch between multiple extraction and beverage preparation scenarios, meeting different beverage preparation needs and improving the extraction quality. Furthermore, unlike setting multiple valves to control the opening and closing of the second liquid pipe 102 and the second outlet 1303, the setting of the liquid outlet control valve 130 improves the integration performance of the heating device 100, reduces the number of valves, and thus facilitates the miniaturization of the heating device 100 and reduces costs.

[0047] It should be noted that the liquid outlet control valve 130 can be a solenoid valve or a mechanical valve. The liquid outlet control valve 130 can be a three-way valve or a four-way valve, etc., without further restrictions.

[0048] Specifically, in one embodiment, the heating device further includes a pressure relief switch. The pressure relief switch is connected to the second outlet end 1303 of the liquid outlet control valve 130. The pressure relief switch is used to switch from a closed state to an open state when the operating pressure in the second liquid pipe 102 is greater than a preset pressure, thereby relieving pressure at the second outlet end 1303. Thus, when the operating pressure in the second liquid pipe 102 is greater than the preset pressure, the pressure relief switch is in the open state, allowing the second liquid pipe 102 to communicate with the outside. When the operating pressure is less than or equal to the preset pressure, the pressure relief switch is in the closed state, preventing the second liquid pipe 102 from communicating with the outside.

[0049] In this way, the pressure relief switch can be used to relieve pressure in the second liquid pipe 102, ensuring the safety performance of the heating device 100. The pressure relief switch can be a mechanical pressure relief valve or an electronic pressure relief switch, etc.

[0050] In another embodiment, the beverage making device further includes a waste discharge component, which is connected to the liquid outlet 1202 of the instant heating component 120. In one example, the second outlet 1303 is connected to the waste discharge component of the beverage making device. In this case, the liquid outlet 1202 of the instant heating component 120 is connected to the second outlet 1303 through the second liquid pipe 102, and the liquid outlet of the instant heating component 120 is depressurized through the waste discharge component.

[0051] Understandably, the waste discharge component enables the pressure relief function of the instant heating component and also handles waste liquid generated during the operation of the beverage making equipment. Specifically, when neither the storage heating component 110 nor the instant heating component 120 is working or has not reached the appropriate temperature, some liquid that does not meet beverage standards will be generated. This liquid can flow into the waste discharge component through the second outlet 1303, improving the safety and reliability of the beverage making equipment's operation, effectively handling waste liquid, and ensuring the normal use of the equipment and the quality of the beverage.

[0052] Optionally, in one embodiment, the heating device 100 further includes at least two flow meters 140 and a multi-way connector 150. The beverage making device has at least two brewing chambers, and the third liquid pipe 103 is provided with multiple branch pipes 104. The third liquid pipe 103 is connected between the first outlet end 1302 and the multi-way connector 150. Each branch pipe 104 is connected to the inlet end 1401 of the multiple flow meters 140 through the multi-way connector 150. The outlet ends 1402 of at least two flow meters 140 are respectively connected to at least two brewing chambers through pipelines.

[0053] Specifically, the branch pipe 104 in the third liquid pipe 103 that is connected to the first outlet end 1302 is connected to the other branch pipes 104 through the multi-port connector 150. The other branch pipes 104 are connected to the inlet ends 1401 of multiple flow meters 140 one by one, so that the amount of hot water entering different brewing chambers can be measured by multiple flow meters 140, which improves the accuracy of different brewing and extraction processes and optimizes the extraction and brewing effect.

[0054] Optionally, the at least two brewing chambers in the above embodiments can be used to extract the same beverage or to extract different beverages. For example, one brewing chamber can be used to brew tea, and the other brewing chamber can be used to brew coffee.

[0055] In some embodiments, such as Figure 6 As shown, the heating device 100 also includes a control component 300.

[0056] In one embodiment, the control component 300 is a control component of a beverage making device. The control component 300 is electrically connected to the first heating element and the second heating element. The control component is used to control the energization state and / or output power of the first heating element and / or the second heating element.

[0057] In some embodiments, the first heating element is controlled by intermittent frequency switching, and the second heating element's output power is adjusted by the control component of the beverage making device to reheat the liquid (hot water) after it has been heated by the heat storage heating component. By precisely controlling the output power of the second heating element through the control component, the heating device can flexibly adjust the hot water temperature according to the different beverage preparation requirements, enriching the beverage making scenarios. For example, when making tea, the control component can increase the output power of the second heating element to allow the hot water to reach a higher temperature, fully extracting the aroma and nutrients of the tea leaves. When making coffee, the control component can relatively reduce the output power of the second heating element to maintain a moderate hot water temperature, preventing the coffee from being extracted at excessively high temperatures and producing a bitter taste.

[0058] In another embodiment, the control component 300 is communicatively connected to the liquid outlet control valve 130. The control component 300 is used to control the liquid outlet control valve 130 to switch between a first open state and a second open state according to control commands. In this way, by controlling the liquid outlet control valve 130 through the control component 300, the electronic control process of hot water output is realized, thereby improving the intelligence level of the beverage making equipment.

[0059] Furthermore, in one embodiment, such as Figure 5 As shown, the heating device 100 further includes a first temperature detection element 160. The first temperature detection element 160 is connected to the heat storage heating assembly 110, and at least a portion of the first temperature detection element 160 is disposed within the heating chamber 111. The first temperature detection element 160 is used to detect the liquid temperature within the heating chamber 111 and control the heating of the first heating element 112 based on the detected temperature.

[0060] For ease of understanding, the following explanation will focus on the process of controlling the liquid outlet control valve 130 based on the liquid temperature detected by the first temperature sensor 160 in an example scenario. However, the switching process by which the control component 300 controls the liquid outlet control valve 130 to switch between a first open state and a second open state based on the liquid temperature is not limited to this example scenario.

[0061] Specifically, in this example scenario, the control command includes a first preset temperature. When the liquid temperature in the heating chamber 111 is lower than the first preset temperature, it means that the hot water temperature in the heating chamber 111 is insufficient and needs to be heated further. At this time, the control component of the beverage making device will control the first heating element to be turned on for heating 112 or adjust the heating power or heating frequency of the first heating element 112 when the first heating element is working.

[0062] Generally, the first preset temperature can be used as the minimum standard value for defining different temperatures of hot water required for different beverages. This setting allows the hot water output from the heating chamber 111 to only need to be kept warm when passing through the instant heating component 120 when low-temperature brewing or extraction is required, without the need for further heating, thus meeting the requirements for the minimum brewing or extraction temperature.

[0063] Furthermore, such as Figure 5 as well as Figure 6 As shown, the heating device 100 also includes a second temperature detection element 170. The second temperature detection element 170 is connected to the liquid outlet disposed in the second liquid pipe 102 or the instant heating element 120. The control component 300 of the beverage making equipment is communicatively connected to the second temperature detection element 170 and the second heating element 122. The second temperature detection element 170 is used to detect the liquid temperature in the second liquid pipe 102.

[0064] Specifically, the second temperature detection element 170 is connected to the liquid outlet of the second liquid pipe 102 or the instant heating component 120. This means that the detection end of the second temperature detection element 170 is located inside the liquid outlet of the second liquid pipe 102 or the instant heating component 120, so that the detection end can be wetted by the fluid inside the liquid outlet of the second liquid pipe 102 or the instant heating component 120, thereby realizing the detection of the liquid temperature inside the liquid outlet of the second liquid pipe 102 or the instant heating component 120 by the second temperature detection element 170.

[0065] The control component 300 is used to adjust the output power of the second heating element 122 so that the liquid temperature output from the instantaneous heating component 120 reaches the second preset temperature.

[0066] In addition, the control component 300 can also control the liquid discharge control valve 130 to switch between a first open state and a second open state based on the temperature detected by the second temperature sensor 170.

[0067] Specifically, when the temperature of the liquid heated by the instant heating element 120 reaches the second preset temperature, the control element 300 controls the liquid outlet control valve 130 to be in the first open state. The second preset temperature is the target temperature required for beverage brewing or extraction. At this time, the liquid outlet control valve 130 can be placed in the first open state, allowing the liquid to enter the third liquid pipe 103 through the second liquid pipe 102, and then enter the brewing chamber through the third liquid pipe 103. When the temperature of the liquid heated by the instant heating element 120 is lower than the second preset temperature, the control element 300 adjusts the output power of the second heating element 122 for heating. During this process, the control valve 130 can be in the second open state, discharging the liquid that has not reached the target temperature through the second outlet 1303. This allows for precise control of the liquid temperature for brewing or extraction, optimizing the extraction effect.

[0068] It is understandable that the liquid temperature in the second liquid tube 102 is detected by the second temperature detection element 170, thereby providing feedback on whether the hot water temperature has reached the extraction temperature (i.e., the second preset temperature) requirement. When the liquid temperature in the second liquid tube 102 reaches the second preset temperature, it indicates that the hot water temperature has reached the extraction temperature requirement, and the output power of the second heating element 122 is maintained. When the liquid temperature in the second liquid tube 102 is less than or equal to the second preset temperature, it indicates that the hot water temperature has not reached the extraction temperature requirement, and the output power of the second heating element 122 is increased.

[0069] Thus, by adjusting the output power of the second heating element 122, real-time multi-level hot water temperature adjustment can be achieved to meet the requirements of various extraction temperatures, enabling the high-quality production of various beverages. Furthermore, the first temperature detection element 160 and the second temperature detection element 170 in this application can be NTC sensors, thermocouple sensors, RTD sensors, or IC sensors, etc.

[0070] In some embodiments, a third preset temperature is also provided. When the first temperature sensor 160 or the second temperature sensor 170 exceeds the third preset temperature, the heating device is depressurized. At this time, the control component 300 controls the liquid outlet control valve 130 to switch to the second open state.

[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
