Description

Technical Field

[0001] Some embodiments of the present invention relate to a coffee machine, and particularly to a water heating control method, a coffee powder extraction method, a water heating device, and a coffee machine. Background Art

[0002] A portable coffee machine is a portable device that can directly extract coffee powder or coffee capsules. Due to its small size and portability, users can drink freshly ground coffee anytime and anywhere.

[0003] Furthermore, to allow users to enjoy coffee anytime, anywhere, current portable coffee machines not only store and heat water but also use the heated water to extract coffee powder. However, the inventors discovered that due to the different boiling points of water at high altitudes and on plains, when used at high altitudes, the water may reach a relatively low boiling point and boil at 92°C. At this point, no matter how much the water is heated, its temperature cannot continue to rise. Consequently, once the set water temperature exceeds the boiling point, the coffee machine will continue to heat without stopping, which can not only damage the coffee machine but also pose a safety hazard, easily scalding the user. Furthermore, water nearing or reaching its boiling point produces a large amount of air. This water vapor mixture significantly affects the vacuum formed by the water pump, causing the pump to lose pressure and thus preventing the pump from discharging water. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to design a water heating control method, a coffee powder extraction method, a water heating device, and a coffee machine, so that when the coffee machine is used in high-altitude areas, it can effectively avoid the problem of continuous water heating without stopping due to the low boiling point of water, thereby ensuring the safe use of the coffee machine and avoiding safety hazards.

[0005] To achieve the above objectives, some embodiments of the present invention provide a water heating control method, which is applied to a coffee machine. The water heating control method includes the following steps:

[0006] Get the water temperature T0 and heating time M0 of the coffee machine in real time when heating water;

[0007] Determine whether to continue heating the water based on the obtained water temperature T0 and heating time M0;

[0008] If it is determined that the water is no longer to be heated, the instruction to stop heating the water is executed, so that the currently obtained water temperature reaches the preset water temperature T1, or the currently obtained water temperature reaches the highest water temperature T2 which is lower than the preset water temperature T1.

[0009] In addition, some embodiments of the present invention further provide a coffee powder extraction method, characterized in that the extraction method comprises the following steps:

[0010] The control method described above is used to heat the water stored in the liquid tank of the coffee machine;

[0011] After the water is heated, the water stored in the liquid tank is extracted and continuously pumped into the powder cup of the coffee machine to extract the coffee powder contained in the powder cup.

[0012] In addition, some embodiments of the present invention further provide a water heating device, comprising:

[0013] A heating module heats the water stored in the liquid tank of the coffee machine;

[0014] a temperature detection module, for detecting in real time the temperature of water when it is heated by the heating module;

[0015] A timing module is used to detect the heating time of water when it is heated by the heating module:

[0016] Among them, the heating module, the temperature detection module and the timing module are all communicatively connected to the main control module of the coffee machine, and are used to enable the main control module to obtain the water temperature measured by the temperature detection module and the heating time measured by the timing module in real time, and to enable the main control module to determine whether to continue heating the water based on the obtained water temperature and heating time, and when it is determined that the water heating is no longer to be continued, control the heating module to perform a shutdown operation, so that the water temperature currently measured by the temperature detection module reaches the preset water temperature, or the water temperature currently measured by the temperature detection module reaches the highest water temperature lower than the preset water temperature.

[0017] In addition, some embodiments of the present invention further provide a coffee machine, comprising:

[0018] Liquid tank, used to store water;

[0019] The water heating device as described above is provided on the liquid tank and is used to heat the water in the liquid tank;

[0020] Powder cup, used to hold coffee powder;

[0021] a liquid pumping device, connected to the liquid tank and the powder cup, respectively, for extracting water from the liquid tank and continuously pumping the extracted water into the powder cup;

[0022] A main control module is communicatively connected with the liquid pumping device and the water heating device respectively;

[0023] The main control module is used to control the water heating device according to the instruction, so that the water heating device heats the water in the liquid tank;

[0024] The main control module is also used to control the pumping device according to instructions after the water heating device completes heating the water, so that the pumping device extracts water from the liquid tank and continuously pumps the extracted water into the powder cup to extract the coffee powder in the powder cup.

[0025] Compared to the prior art, the embodiments of the present invention, when heating water, can obtain the water temperature and heating duration in real time. Based on the obtained water temperature and heating duration, the coffee machine can determine whether to continue heating the water. If it is determined that water heating is no longer necessary, a command to stop heating the water can be executed, causing the currently obtained water temperature to reach a preset water temperature T1, or to reach a maximum water temperature T2 that is less than the preset water temperature T1. Therefore, when the coffee machine is used in a high-altitude environment, the coffee machine can be effectively prevented from continuously heating without stopping when the preset water temperature is greater than the boiling point. This not only protects the coffee machine and avoids safety hazards during use, but also reduces the generation of water vapor mixture in the pumping device, maintains the pressure of the pumping device, and improves the stability and reliability of the pumping device during coffee extraction.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that many technical details are provided in the embodiments of the present invention to help readers better understand the present application. However, even without these technical details and the various variations and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented.

[0036] Example 1

[0037] The first embodiment of the present invention relates to a water heating control method, which is applied to a coffee machine, and Figure 1 As shown, the water heating control method includes the following steps:

[0038] Step 110 , obtaining in real time the water temperature T0 and the heating time M0 of the coffee machine when heating water.

[0039] Step 120 : Determine whether to continue heating the water based on the obtained water temperature T0 and heating time M0 .

[0040] In step 130, if it is determined that the water heating is no longer to be continued, the instruction to stop heating the water is executed, so that the current water temperature reaches the preset water temperature T1, or the current water temperature reaches the maximum water temperature T2 which is lower than the preset water temperature T1. If it is determined that the water heating is to be continued, the process returns to step 110.

[0041] As can be readily seen from the foregoing, when the coffee machine is heating water, the water temperature and heating duration are acquired in real time, and the machine determines whether to continue heating the water based on the acquired water temperature and heating duration. If it is determined that the water heating is no longer appropriate, a command to stop heating the water is executed, causing the currently acquired water temperature to reach a preset water temperature T1, or a maximum water temperature T2 that is less than the preset water temperature T1. Therefore, when the coffee machine is used at high altitudes, the machine can effectively prevent continuous heating without stopping when the preset water temperature is above the boiling point. This not only protects the coffee machine and avoids potential safety hazards during use, but also reduces the generation of water vapor mixtures in the pumping device, ensuring pressure in the pumping device, and improving the operational stability and reliability of the pumping device when extracting coffee powder.

[0042] Specifically, in some embodiments, in the step of determining whether to continue heating the water based on the obtained water temperature T0 and heating time M0, step 120 specifically includes:

[0043] If the currently obtained water temperature T0 is lower than the preset water temperature T1, and the heating time M0 when the currently obtained water is heated to the water temperature T0 is lower than the preset time M1, it is determined to continue heating the water.

[0044] If the currently obtained water temperature T0 is lower than the preset water temperature T1, and the heating time M0 when the currently obtained water is heated to the water temperature T0 is equal to or greater than the preset time M1, it is determined that the heating is no longer continued.

[0045] If the currently obtained water temperature T0 is equal to the preset water temperature T1, it is determined that the water is no longer to be heated.

[0046] For example, in some embodiments, when the coffee machine is used in a high-altitude environment, such as an altitude of 2000 meters, the boiling point of water is approximately 93°C. Therefore, if the preset water temperature T1 used by the coffee machine to heat the water is greater than 93°C, for example, if the preset water temperature is set to 96°C, the coffee machine will only be able to heat the water to 93°C at most, and will not be able to heat the water to 96°C. Therefore, in some embodiments, if the coffee machine takes approximately 60 seconds to heat water from room temperature to 93°C, the coffee machine can set the preset water heating time M1 to be greater than 60 seconds, such as 70 seconds. Therefore, if the current water temperature T0 is less than the preset water temperature T1, i.e., T0 < 96°C, and the heating time M0 for the current water to reach the water temperature T0 is less than the preset time M1, i.e., M0 < 70 seconds, it indicates that the water temperature can continue to rise, and it can be determined that the water can continue to be heated. On the contrary, when the currently obtained water temperature T0 is lower than the preset water temperature T1, that is, T0<96℃, and the heating time M0 when the currently obtained water is heated to the water temperature T0 is greater than or equal to the preset time M1, that is, M0≥70s, it means that the water temperature at this time has reached the maximum water temperature and the water temperature cannot continue to rise. At this time, it can be determined that the water heating is no longer required, so that the coffee machine can execute the stop water heating instruction and make the current water temperature T0 reach the maximum water temperature T2 which is lower than the preset water temperature T1, that is, the current water temperature reaches the boiling point of water 93℃.

[0047] Similarly, in a high-altitude environment, if the preset water temperature is set to 90°C, the coffee machine will take less than 60 seconds to heat the water from room temperature to 90°C, and therefore must be less than the preset time M1, that is, M0 < 70s. Therefore, when the current water temperature T0 reaches the preset water temperature T1, that is, T0 = 90°C, it can be determined that the water should no longer be heated, so that the coffee machine can execute the stop water heating instruction and make the current water temperature T0 reach the preset water temperature T1, that is, T0 = T1 = 90°C.

[0048] Furthermore, it is worth noting that when the coffee machine is used in a plain environment, since the boiling point of water is 100°C, in some embodiments, if the heating time for the coffee machine to heat water from room temperature to 100°C is approximately 65 seconds, the control method for heating water in a plateau environment is also applicable to a plain environment. For example, if the currently obtained water temperature T0 is less than 100°C, T0 < 100°C, the heating time for the currently obtained water to be heated to the water temperature T0 must be less than the preset time M1, that is, M0 < 70s, indicating that the water temperature can continue to rise. Similarly, if the currently obtained water temperature T0 is equal to 100°C, that is, T0 = 100°C, the heating time for the currently obtained water to be heated to the water temperature T0 must also be less than the preset time M1, that is, M0 < 70s. It is not difficult to find that when the coffee machine is used in a plain environment, no matter how much the preset water temperature T1 is set to, the coffee machine can heat the water to that temperature very well. However, it should be noted that the preset time M1 set in the coffee machine should be as long as possible greater than or equal to the heating time when the water is heated to 100°C, so that the coffee machine can meet the usage requirements in both plain and high-altitude environments.

[0049] In addition, as a preferred solution, in other embodiments, after executing the instruction to stop heating water, that is, after step 130, as shown in FIG. Figure 2 As shown, the water heating control method further includes the following steps:

[0050] Step 140: Determine whether the coffee machine is currently in a high altitude environment based on the currently obtained water temperature.

[0051] Step 150: If the coffee machine is determined to be in a high altitude environment, a prompt message is issued. For example, the prompt message includes at least one of a first message notifying the user that the coffee machine is in a high altitude environment and a second message for the user to readjust the preset water temperature T1.

[0052] As can be seen from this, once the coffee machine has finished heating the water, it can use the current water temperature to determine whether it is in a high-altitude environment. Once the coffee machine determines it is in a high-altitude environment, it will issue a prompt message to alert the user. Furthermore, the user can use this prompt message to promptly adjust the coffee machine's preset water temperature T1, further protecting the coffee machine and effectively reducing the coffee machine's energy consumption when heating water.

[0053] Furthermore, it should be noted that the first information in the prompt message can be a light alarm, an audible alarm, or an audible and visual alarm. Therefore, when the first information is a light alarm, a light alarm unit such as an LED or light-emitting diode can be provided on the coffee machine to provide a light alarm prompt. When the first information is an audible alarm, a audible alarm unit such as a buzzer or speaker can be provided on the coffee machine to provide an audible alarm prompt. Of course, in other embodiments, a display can be provided on the coffee machine to display the first information in the form of text or code. To enable the coffee machine to emit the second information, in other embodiments, the coffee machine can also be provided with a display module that can display the current preset water temperature T1 set by the coffee machine. Physical or touch buttons can also be provided on the coffee machine to adjust the current preset water temperature T1. Of course, as an alternative, a touch display module, such as a touch screen, can be provided on the coffee machine to simultaneously display the second information and adjust the preset water temperature T1, thereby further improving the practicality of the coffee machine.

[0054] Example 2

[0055] The second embodiment of the present invention relates to a coffee powder extraction method, which is applied to a coffee machine, and Figure 3 As shown, the extraction method comprises the following steps:

[0056] In step 210 , the water stored in the liquid tank 1 of the coffee machine is heated using the control method described in the first embodiment.

[0057] In step 220 , after the water is heated, the water stored in the liquid tank 1 is extracted and continuously pumped into the coffee machine's powder cup 2 to extract the coffee powder in the powder cup 2 .

[0058] As can be readily seen from the foregoing, when the coffee machine is extracting ground coffee, it can first obtain the water temperature and heating duration in real time within the liquid reservoir 1. Based on the obtained water temperature and heating duration, it can determine whether to continue heating the water. If it is determined that water heating is no longer necessary, it can execute a command to stop heating the water, causing the currently obtained water temperature to reach a preset water temperature T1, or to reach a maximum water temperature T2 that is less than the preset water temperature T1. Therefore, when the coffee machine is used in a high-altitude environment, when the preset water temperature is greater than the boiling point of water, the coffee machine can be effectively prevented from continuously heating without stopping. This not only protects the coffee machine and avoids potential safety hazards during use, but also reduces the generation of water vapor mixtures in the pumping device, ensuring pressure in the pumping device. This improves the operational stability and reliability of the pumping device when the coffee machine is extracting ground coffee.

[0059] In addition, it is worth mentioning that after the heating of the water is completed, that is, after step 210, and before the water stored in the liquid tank 1 is extracted, that is, before step 220, as shown in FIG. Figure 4 As shown, the coffee powder extraction method further includes the following steps:

[0060] Step 211, obtaining the current amount of water in the liquid tank 1.

[0061] Step 212: Determine, based on the obtained amount of water, whether the amount of water meets the water amount required for one extraction of coffee powder.

[0062] If it is determined that the water volume satisfies the water volume for one extraction of coffee powder, step 220 is executed, i.e., water stored in the liquid tank 1 is extracted and the extracted water is continuously pumped into the powder cup 2 of the coffee machine to extract the coffee powder in the powder cup 2.

[0063] Step 213: If it is determined that the amount of water required for one extraction of coffee powder is not sufficient, a prompt message is issued.

[0064] When the water is heated to a preset temperature T1 or to a maximum temperature T2 less than the preset temperature T1, the amount of water currently in the liquid reservoir 1 may be insufficient for a single extraction of the coffee powder due to evaporation. Therefore, to prevent insufficient water in the liquid reservoir 1 from causing inadequate extraction of the coffee powder, the current amount of water in the liquid reservoir 1 needs to be detected after the water is heated and before the water stored in the liquid reservoir 1 is drawn to extract the coffee powder in the powder cup 2. Therefore, in some embodiments, a liquid level sensor (not shown) may be provided in the coffee machine to detect the water level in the liquid reservoir 1. The main control module 5 of the coffee machine can also calculate and determine the current amount of water in the liquid reservoir 1 based on the water level measured by the liquid level sensor, and compare this amount with the preset amount of water for a single extraction of the coffee powder. Specifically, if the currently obtained amount of water is less than the preset amount, it indicates that the current amount of water in the liquid reservoir 1 is insufficient. In this case, the coffee machine may issue a prompt message to remind the user to refill the liquid reservoir 1 with water. Conversely, if the currently obtained water volume is equal to or greater than the preset water volume, it indicates that the current water volume in the liquid tank 1 is sufficient. The main control module 5 of the coffee machine can then control the pumping device 4 to extract water from the liquid tank 1 and continuously pump the extracted water into the powder cup 2 to extract the coffee powder in the powder cup 2. Furthermore, it should be noted that the method for obtaining the water volume in the above embodiment is based solely on detecting the water level in the liquid tank 1 using a liquid level sensor. In other embodiments, the water volume in the liquid tank 1 can also be obtained by weighing the liquid tank 1. In this embodiment, the method for obtaining the water volume in the liquid tank 1 is not specifically limited.

[0065] From the above content, it can be seen that after the water is heated, it is necessary to obtain the water amount in the liquid tank 1 to determine whether the current water amount meets the water amount for one extraction of coffee powder. Therefore, based on this solution, in order to avoid the phenomenon of empty burning of the liquid tank 1 due to too little water in the liquid tank 1, in other embodiments, before adopting the water heating control method as described in Example 1 to heat the water stored in the liquid tank 1 of the coffee machine, that is, before step 210, as shown in FIG. Figure 4 As shown, the coffee powder extraction method further includes the following steps:

[0066] Step 201, obtaining the current amount of water in the liquid tank 1.

[0067] Step 202: Determine, based on the obtained amount of water, whether the amount of water meets the water amount required for one extraction of coffee powder.

[0068] If the water volume is determined to be sufficient for a single extraction of the coffee powder, step 210 is executed, where the water stored in the liquid reservoir 1 of the coffee machine is heated using the control method described in Example 1. If the water volume is determined to be insufficient for a single extraction of the coffee powder, step 213 is executed, where a prompt message is issued. It should be noted that the prompt message mentioned in this embodiment may be a visual alarm, an audible alarm, or an audible and visual alarm. Therefore, if the prompt message is a visual alarm, a light alarm unit such as an LED light source or a light-emitting diode may be provided on the coffee machine to provide a visual alarm. If the prompt message is an audible alarm, a buzzer or speaker may be provided on the coffee machine to provide an audible alarm. Of course, in other embodiments, a display may be provided on the coffee machine to display text or code information in real time for prompts.

[0069] Example 3

[0070] The third embodiment of the present invention relates to a water heating device, such as Figure 9 As shown, the water heating device 3 includes a heating module 31, a temperature detection module 32, and a timing module 33. The heating module 31 heats the water stored in the coffee machine liquid tank 1. The temperature detection module 32 is used to detect the water temperature of the water being heated by the heating module 31 in real time, while the timing module 33 is used to detect the heating duration of the water being heated by the heating module 31.

[0071] Among them, combined Figure 9 As shown, the heating module 31, the temperature detection module 32, and the timing module 33 are all communicatively connected to the main control module 5 of the coffee machine, so that the main control module 5 can obtain the water temperature measured by the temperature detection module 32 and the heating time measured by the timing module 33 in real time. The main control module 5 can also determine whether to continue heating the water based on the obtained water temperature and heating time. If it is determined that the water heating is no longer necessary, the heating module 31 is controlled to shut down the coffee machine, so that the water temperature currently measured by the temperature detection module 32 reaches a preset water temperature, or the water temperature currently measured by the temperature detection module 32 reaches a maximum water temperature that is lower than the preset water temperature. As can be seen from this, when the coffee machine is used in a high-altitude environment, when the preset water temperature is greater than the boiling point of water, the coffee machine can be effectively prevented from continuously heating without shutting down. This not only protects the coffee machine and avoids safety hazards during use, but also reduces the generation of water vapor mixture in the pumping device, ensuring the pressure of the pumping device, and improving the stability and reliability of the pumping device during operation when the coffee machine is extracting coffee powder.

[0072] Specifically, in some embodiments, the temperature detection module 32 may be a temperature sensor, and the timing module 33 may be a timer, or the timing module 33 may be integrated into the main control module 5. In addition, in order to enable the heating module 31 to effectively heat the water in the liquid tank 1, in some embodiments, such as Figure 7 and Figure 8 As shown, the heating module 31 includes: a metal substrate 311 disposed at the bottom of the liquid tank 1, and a heating thick film 312 disposed on the metal substrate 311. The heating thick film 312 is electrically connected to the main control module 5, so that the main control module 5 can control the heating thick film 312 to generate heat. It is not difficult to see that the entire metal substrate 311 can be transformed into a heating plate under the action of the heating thick film 312, so that when it generates heat, it can transfer its own heat to the liquid tank 1, thereby heating the water in the liquid tank 1. It should also be noted that the heating module 31 in the above embodiment can also use other heating elements. In this embodiment, the structure and type of the heating module 31 are not specifically limited.

[0073] However, as a preferred solution, the metal substrate 311 in the heating module 31 can also be used as the bottom of the liquid tank 1, and the metal substrate 311 can be welded to the side wall of the liquid tank 1 (not shown in the figure), so that the liquid tank 1 can not only store water, but also directly heat the water. While improving the heating efficiency, it can also reduce the overall mass and volume of the coffee machine, making the coffee machine easier to carry, thereby further improving the convenience of the coffee machine.

[0074] As can be readily seen from the foregoing, this embodiment is an embodiment of a water heating device corresponding to Example 1, and this embodiment can be implemented in conjunction with Example 1. The relevant technical details mentioned in Example 1 remain valid in this embodiment and, to reduce repetition, are omitted here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied in Example 1.

[0075] Example 4

[0076] The fourth embodiment of the present invention relates to a coffee machine, such as Figure 5 and Figure 6 As shown, the coffee machine includes: a liquid tank 1, a water heating device 3 as described in the third embodiment, a powder cup 2, a liquid pump device 4 and a main control module 5.

[0077] The water heating device 3 is arranged on the liquid tank 1, specifically as follows Figure 5 As shown, the heating module 31 of the water heating device 3 composed of the metal substrate 311 and the heating thick film 312 can be set at the bottom of the liquid tank 1, and the water heating device 3 is used to heat the water in the liquid tank 1. Secondly, the powder cup 2 is used to hold coffee powder. In addition, as Figure 6As shown, the pumping device 4 is connected to the liquid tank 1 and the powder cup 2 respectively. The pumping device 4 is used to extract water from the liquid tank 1 and continuously pump the extracted water into the powder cup 2. Finally,

[0078] In addition, if Figure 9 As shown, the main control module 5 is in communication with the liquid pumping device 4 and the water heating device 3. When the main control module 5 receives a command, it first controls the water heating device 3 according to the command, causing the water heating device 3 to heat the water in the liquid tank 1. Furthermore, after the water heating device 3 finishes heating the water, the main control module 5 controls the liquid pumping device 4 according to the command, causing the pumping device 4 to extract water from the liquid tank 1 and continuously pump the extracted water into the coffee cup 2 to extract the coffee powder contained in the coffee cup 2.

[0079] As can be readily seen from the foregoing, this embodiment is a coffee machine embodiment corresponding to Example 2, and can be implemented in conjunction with Example 2. The relevant technical details mentioned in Example 2 remain valid in this embodiment and, to reduce repetition, are omitted here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied in Example 2.

[0080] Those skilled in the art will appreciate that the above embodiments are specific embodiments for implementing the present invention, and that in actual applications, various changes may be made in form and detail without departing from the spirit and scope of the present invention.
