[0017] Figure 1 This is a schematic diagram of an embodiment of a coffee machine with a dehumidification function provided by the utility model. DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] The utility model provides a coffee machine with a dehumidification function, which can discharge moisture generated in the coffee machine during the coffee extraction process, reduce the humidity of the internal space of the coffee machine, prevent organic matter therein from breeding fungi, effectively ensure the health of users, and reduce the probability of failure of the coffee machine.
[0020] The coffee machine with dehumidification function provided by the utility model is implemented as follows Figure 1 As shown, Figure 1The present invention is a schematic diagram of an embodiment of a coffee machine with a dehumidification function provided by the utility model. The coffee machine with a dehumidification function may include a coffee machine body 1. The coffee machine body 1 is provided with an internal air pressure regulating system 3 which is communicatively connected to a control device 2, a dehumidification start determining device 4 and a dehumidification end determining device 5. The internal air pressure regulating system 3 may include an internal air pressure regulating device 31 which is communicatively connected to the control device 2, an exhaust port 32 and an air inlet 33 which are provided on the coffee machine body 1 and communicate with the outside world. The internal air pressure regulating device may be, but is not limited to, an exhaust fan which is arranged adjacent to the exhaust port 32. In this case, a negative pressure environment may be formed inside the coffee machine, and the hot and humid gas in the coffee machine may be extracted and discharged from the exhaust port 32 to the outside world. Thereby, moisture is prevented from staying in the space inside the coffee machine, and external dry gas is introduced into the coffee machine from the air inlet 33 to realize air exchange. Moreover, the internal air pressure regulating device 31 can also be selected as an inlet fan arranged close to the air inlet 33, and the inlet fan can preferably be connected to a compressed gas container, which can preferably contain an inert gas, such as argon, nitrogen, etc., so that a higher pressure dry gas can be filled into the coffee machine. In this case, the high-pressure gas is used to push the hot and humid gas inside the coffee machine outward and push it out from the exhaust port 32 to the external environment, so that the internal environment of the coffee machine is drier and bacteria are avoided. It can be seen that these two methods can achieve the same purpose of discharging moisture. It should also be noted that Figure 1The numbers in brackets of the icons in the figure represent major categories, while the numbers outside the brackets represent minor categories. For example, 31 (3) indicates that the internal air pressure regulating device 31 is a part of the internal air pressure regulating system 3, and the internal air pressure regulating system 3 also includes an exhaust port 32 and an air inlet 33, wherein the air path between the air inlet 33 and the exhaust port 32 passes through the steam evaporation position of the brewing device 6 in the coffee machine body 1, and the opening position of the air inlet 33 must ensure that no turbulence is generated to avoid bringing coffee powder into an inappropriate space and making it unable to come out. It should be noted that the steam evaporation position is generally located above the brewing device 6, because steam naturally flows upward. In this case, the gas on the above-mentioned air path can be used to more accurately remove the moisture generated at the steam evaporation position to avoid moisture remaining in the coffee machine. The moisture removed is It can be discharged from the exhaust port 32 to the external environment, and the vertical distance between the center of the exhaust port 32 and the brewing device 6 can preferably be 10 cm to 15 cm, so that it can be closer to the place where the steam is concentrated, so as to take away the humid air more efficiently. Moreover, the control device 2 is used to start the internal air pressure regulating system 3 for dehumidification after receiving the dehumidification start signal sent by the dehumidification start determination device 4, and stop the internal air pressure regulating system to end dehumidification after receiving the dehumidification end signal sent by the dehumidification end determination device 5. It should be noted here that after each coffee extraction is completed, the dehumidification purpose can be achieved after it continues for a certain period of time. Therefore, it can be set here to automatically start dehumidification, and automatically turn off the dehumidification after the dehumidification target is reached. No personnel supervision and intervention are required, thereby freeing up manpower and saving energy consumption. It should also be noted that Figure 1 It is also shown that the coffee machine body 1 also has a water tank 7, a flow meter 8, a water pump 9, a heating unit 10, a powder collector 11, a coffee spout 12 and a water receiving tray 13, which are the basic structures of the coffee machine and will not be described in detail here.
[0021] It can be seen from the above technical scheme that in the embodiment of the above-mentioned coffee machine with dehumidification function provided by the utility model, since the coffee machine body is provided with an internal air pressure regulating system, a dehumidification start determining device and a dehumidification end determining device which are communicatively connected to the control device, the internal air pressure regulating system includes an internal air pressure regulating device which is communicatively connected to the control device, an exhaust port and an air inlet which are opened on the coffee machine body and connected to the outside world, wherein the air path between the air inlet and the exhaust port passes through the steam evaporation position of the brewing device in the coffee machine body, and the control device is used to start the internal air pressure regulating system for dehumidification after receiving the dehumidification start signal issued by the dehumidification start determining device, and stop the internal air pressure regulating system to end dehumidification after receiving the dehumidification end signal issued by the dehumidification end determining device. Therefore, these components can be used to discharge the moisture generated in the coffee machine due to the coffee extraction process, reduce the humidity in the internal space of the coffee machine, avoid the growth of fungi from organic matter therein, effectively ensure the health of the user, and reduce the probability of failure of the coffee machine.
[0022] In a specific embodiment of the above-mentioned coffee machine with dehumidification function, the dehumidification start determining device 4 can preferably be a position sensor arranged next to the brewing device 6, and the position sensor is used to detect the signal of the brewing device returning to its original position after brewing is completed. It should be noted that, in this case, when the brewing device finishes brewing, it will return to its original position. At this time, the position sensor can detect its return to its original position, and then send a relevant signal to the control device 2 according to this situation, so that the control device 2 can control the start of the dehumidification process. It can be seen that there is no need for relevant personnel to start the dehumidification, not only the start timing is controlled more accurately, but also the maximum power saving effect can be achieved. In a further embodiment, the position sensor can preferably be an infrared sensor, a micro switch or a rebound displacement sensor, which can be selected according to actual needs. Taking the infrared sensor as an example, an infrared emitting component can be set on the first side of the brewing device 6, and an infrared receiving component can be set on the second side opposite to it. During the coffee brewing process, since the brewing device 6 is in the upper position, the front of the infrared emitting component will not be blocked by the brewing device 6, and the light of the infrared emitting component can be received by the infrared receiving component on the opposite side. When the brewing process is completed, the brewing device 6 moves down until it blocks the light path of the infrared emitting component. At this time, the infrared receiving component The receiving component cannot receive the infrared light emitted by the infrared emitting component. At this time, a signal can be sent to the control device 2 that the brewing device has finished brewing and returned to its original position, thereby controlling the start of the dehumidification process. It can be seen that the timing of starting dehumidification can be more accurate, and compared with the visible light sensor, this infrared method is not affected by the brightness of the light in the environment, and accurate detection and dehumidification control can be achieved in any environment. When a micro switch is used, it can be installed under or on the side of the brewing device. When the brewing device moves down to its original position, the brewing device presses the micro switch, and after the pressure is applied to the action reed of the micro switch, the action reed is displaced to the critical point to produce an instantaneous action, so that the moving contact at the end of the action reed is quickly connected or disconnected with the fixed contact, thereby sending a signal to the control device 2 that the brewing device has returned to its original position after brewing, thereby controlling the start of the dehumidification process. It can be seen that this method is also not affected by ambient light and has a stronger instant response capability. Of course, it can also be replaced by a rebound displacement sensor to achieve the same function, which will not be repeated here.
[0023] In another specific embodiment of the coffee machine with dehumidification function, the dehumidification end determination device 5 can be preferably a humidity detection device, which is used to compare the collected real-time humidity signal with the preset humidity threshold, and send a dehumidification end signal when the real-time humidity signal is less than the preset humidity threshold. That is to say, as the dehumidification process proceeds, the humidity of the internal environment of the coffee machine becomes lower and lower. When the humidity is lower than the preset humidity threshold, the dehumidification process can be ended. Here, the humidity detection device is used as the dehumidification end determination device, which can more conveniently and accurately determine the dehumidification end point without manual participation, save electricity, and do not need to perform unnecessary dehumidification operations. In a further embodiment, the humidity detection device may preferably be located on the air path between the air inlet and the air outlet to detect the real-time humidity value on the air path. It should be noted that the air path generally passes through the position where dehumidification is most needed. Therefore, by setting a humidity detection device on such an air path, the humidity can be measured more accurately. It is preferably set downwind of the position where dehumidification is most needed. In this way, when the humidity drops to a certain level, it proves that the dehumidification purpose has been achieved. At this time, the dehumidification can be controlled to stop. Of course, the setting position of the humidity detection device can be adaptively adjusted according to actual needs, which is not limited here.
[0024] In another specific embodiment of the coffee machine with dehumidification function, the dehumidification end determination device 5 can also be preferably a timing device, which can be used to start timing after receiving the dehumidification start signal and send a dehumidification end signal after reaching the preset dehumidification time. It should be noted that in this case, a fixed time can be set at the time of leaving the factory, and the timing starts at the same time as the dehumidification is started after each coffee extraction is completed. When the fixed time is reached, the dehumidification process is automatically stopped, which also realizes the automatic start and stop of dehumidification without the participation of personnel, saving labor costs. In a further embodiment, the timing device may preferably be a timing IC arranged on the control device, and the timing IC is connected to a timing button, and the timing button is used to receive a user input instruction for determining the dehumidification time. That is to say, a timing button may be arranged on the external panel of the coffee machine, which may be a button, a knob, or a touch key on a liquid crystal screen. There is no restriction here. The user may change the dehumidification time when necessary. For example, when the humidity of the external air is relatively high, the dehumidification time may be set longer, otherwise it may be set shorter. In this way, corresponding settings may be made according to the actual situation each time, thereby ensuring a better dehumidification effect. Of course, if the dehumidification time is not set before a certain coffee extraction, the dehumidification process may be controlled according to the system default time or the dehumidification time set last time.
[0025] In a preferred embodiment of the coffee machine with dehumidification function, a pipe can be preferably provided on the air path between the air inlet 33 and the air outlet 32. The side of the pipe is densely provided with a plurality of through holes for connecting the space inside and outside the pipe. The through holes are used to introduce the moisture in the space outside the pipe into the space inside the pipe and discharge it to the outside when the pipe is in a negative pressure state. The outside here refers to the environment outside the coffee machine. It should be noted that the through holes provided on the side of the pipe can be circular, square or other shapes. When circular, the diameter of the through holes can be preferably 1mm to 2mm, and the spacing between adjacent through holes can be preferably 2mm to 5mm. In this way, the humid gas outside the pipe can be smoothly introduced into the pipe, and the air flow in the pipe can be effectively ensured to flow accurately to the air outlet, and it is not easy to be dispersed outside the pipe. The use of such a pipe can better guide the direction of the air flow and better prevent the coffee powder from being sucked away. This is because the pipe can be set away from the position where the coffee powder is located. In addition, the exhaust process will cause the gas in the pipe to decrease. In this way, the gas outside the pipe is sucked in under the action of the pressure difference, and the external moisture also enters the pipe with the gas, and finally can be discharged from the exhaust. The air outlet 32 is used to discharge the moisture to the external environment, so as to avoid health hazards caused by excessive moisture in the coffee machine. When the compressed gas is charged from the air inlet 33, the pipe can be of a shorter length. It is only necessary to connect the pipe from the air inlet 33 to the top of the brewing device. In this way, the gas can be pushed to this position in a more direction. At this time, the moisture generated inside the coffee machine can be pushed to the position of the exhaust port 32 along with the gases and finally discharged. Of course, another section of the pipe can be set between the upper position of the brewing device 6 and the position of the exhaust port 32 to achieve more directional gas transmission, so as to achieve the purpose of dehumidification based on the use of less compressed gas, and the production cost and dehumidification cost of the coffee machine will be further reduced.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
