[0033] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0034] Embodiment 1

[0035] In the preferred Embodiment 1 of the present invention, a humidifying device control method is provided. This control method can be directly applied to a humidifying device as shown in Figures 1 to 5 Figure, including: an evaporation cylinder 1, in which a water volatilization component (not shown in the figure) is provided; a water storage tank 3, which is communicated with the evaporation cylinder 1, and the lowest point of the water storage tank 3 is higher than the lowest point of the evaporation cylinder 1, or the lowest point of the water storage tank 3 is at the same horizontal plane as the lowest point of the evaporation cylinder 1; a negative pressure mechanism, which is provided on the water storage tank 3 and can generate negative pressure in the water storage tank 3. Under the action of the negative pressure mechanism, the water storage tank 3 obtains a certain amount of water from the evaporation cylinder 1 for storage, and gradually replenishes water to the evaporation cylinder 1 as the water level in the evaporation cylinder 1 drops, so as to ensure that the water level in the evaporation cylinder 1 always remains within a set range. At this time, the water volatilization component remains partially soaked in the water in the evaporation cylinder 1, so as to ensure the humidifying effect of the water volatilization component, and further ensure the humidifying effect of the humidifying device.

[0036] When the water level in the evaporation cylinder 1 is within the preset range, the humidifying effect of the water evaporation component is relatively high at this time. As the water evaporation component evaporates water, the water in the evaporation cylinder 1 gradually decreases. When the liquid level in the evaporation cylinder 1 is lower than the connection position between the water storage cylinder 3 and the evaporation cylinder 1, air will enter the water storage cylinder 3 through the connection position between the water storage cylinder 3 and the evaporation cylinder 1, so that part of the water in the water storage cylinder 3 flows into the evaporation cylinder 1, the liquid level in the evaporation cylinder 1 rises, and the water volume in the evaporation cylinder 1 returns to the preset range again. At this time, the connection position between the water storage cylinder 3 and the evaporation cylinder 1 is again below the liquid level of the evaporation cylinder 1, and air will not enter the water storage cylinder 3. At this time, the water storage cylinder 3 will not replenish water to the evaporation cylinder 1, thus achieving the purpose of ensuring the water level in the evaporation cylinder 1.

[0037] When the water level in the evaporation cylinder 1 is lower than the preset range and the water volume in the water storage cylinder 3 is also insufficient, water can be added to the evaporation cylinder 1. At the same time, the negative pressure mechanism generates negative pressure in the water storage cylinder 3, so that the water in the evaporation cylinder 1 enters the water storage cylinder 3 under the action of negative pressure and is stored in the water storage cylinder 3. When the water volume in the water storage cylinder 3 reaches the maximum, continue to replenish water to the evaporation cylinder 1 until the water level in the evaporation cylinder 1 reaches the preset range, completing the water replenishment process for the evaporation cylinder 1.

[0038] As an implementation manner, the negative pressure mechanism includes a piston 4. The piston 4 is movably arranged in the water storage cylinder 3, and the piston 4 divides the interior of the water storage cylinder 3 into a water storage chamber 31 and a back pressure chamber 32. The water storage chamber 31 is communicated with the evaporation cylinder 1. The volumes of the water storage chamber 31 and the back pressure chamber 32 are adjustable. As Figure 2 shown, when the humidifying device replenishes water, water is injected into the evaporation cylinder 1. At the same time, when the piston 4 is controlled to move upward, the volume of the water storage chamber 31 gradually increases, while the volume of the back pressure chamber 32 gradually decreases. At this time, the water in the evaporation cylinder 1 will be sucked into the water storage chamber 31 as the volume of the water storage chamber 31 increases. When the piston 4 moves to the highest position above, the water storage chamber 31 is completely filled with water, achieving the purpose of storing water. When the humidifying device stops replenishing water, since the piston 4 remains different, the negative pressure in the water storage chamber 31 will not disappear at this time, so that the water storage in the water storage chamber 31 can be ensured reliably. Only when the water level in the evaporation cylinder 1 is lower than the connection position between the evaporation cylinder 1 and the water storage cylinder 3, air can enter the water storage chamber 31, and the water in the water storage chamber 31 flows into the evaporation cylinder 1. As the water is gradually injected into the evaporation cylinder 1, the water level in the evaporation cylinder 1 increases, closing the connection position between the evaporation cylinder 1 and the water storage cylinder 3, and air stops entering the water storage chamber 31. The water storage chamber 31 also stops replenishing water to the evaporation cylinder 1, achieving the effect of automatic water replenishment.

[0039] The negative pressure mechanism further includes a driving mechanism, which is arranged on the water storage tank 3 or in the back pressure chamber 32, and the piston 4 is connected to the driving mechanism. The driving mechanism can drive the piston 4 to move, so as to achieve the water storage effect of the water storage tank 3.

[0040] Specifically, the driving mechanism includes a driving motor 5 and a rack 6. The rack 6 is arranged on the piston 4, the driving motor 5 is arranged on the water storage tank 3, and the output gear of the driving motor 5 is directly or indirectly meshed with the rack 6.

[0041] The driving motor 5 includes a servo motor. When there is no relevant power signal instruction, the position of the servo motor is in a locked state, so the position of the piston 4 can be kept fixed, thus ensuring the stability of the negative pressure in the water storage chamber 31.

[0042] The water storage tank 3 has an upper cover, and the upper end of the rack 6 can abut against the upper cover to bend the rack 6 in the water storage tank 3. By bending the rack 6, it is possible to avoid the need for a large space when the rack 6 moves upward, thereby reducing the occupied space of the humidifying device.

[0043] A guiding structure 33 is arranged in the water storage tank 3, and the rack 6 can be bent under the guiding action of the guiding structure 33.

[0044] Specifically, the guiding structure 33 includes guiding ribs. The rack 6 has opposite first and second side surfaces. Teeth meshing with the output teeth are arranged on the first side surface. The rack 6 can be bent towards the second side surface under the guiding action of the guiding ribs, avoiding damage to the rack 6 caused by the collision of the teeth on the first side surface during the bending process of the rack 6.

[0045] In order to facilitate the controllable bending of the rack 6, a bending section is arranged at the upper end of the rack 6. When the rack 6 moves upward, the bending section abuts against the upper cover and bends under the extrusion of the upper cover. As the rack 6 continues to move upward, the rack 6 can also bend along the bending arc of the bending section, thereby realizing the controllable bending of the rack 6.

[0046] The guiding structure 33 further includes a limiting rib, which is arranged on the guiding rib, and the limiting rib can prevent the bending degree of the rack 6 from being too large and causing self-interference.

[0047] As an implementation manner, the water storage tank 3 is arranged in the evaporation tank 1, and a communication hole is arranged on the part of the water storage tank 3 located in the evaporation tank 1. The water storage tank 3 is communicated with the evaporation tank 1 through the communication hole.

[0048] The humidifying device further includes a water level detection mechanism 7 which is arranged in the evaporation cylinder 1 and electrically connected to the negative pressure mechanism. The water level detection mechanism 7 can obtain the water level in the evaporation cylinder 1. When the water level is lower than the preset range, the water level detection mechanism 7 can send out a water shortage signal. The control mechanism of the humidifying device receives this water shortage signal and controls the negative pressure mechanism to work in the reverse direction (i.e., making the piston 4 move downward), reducing the negative pressure in the water storage cylinder 3 and making the negative pressure in the water storage cylinder 3 reach the minimum value. Then, the evaporation cylinder 1 is replenished with water. At this time, the water level detection mechanism 7 controls the negative pressure mechanism to work, pumping negative pressure in the water storage cylinder 3, and knowing that the water storage amount in the water storage cylinder 3 reaches the set value, completing the water replenishment operation of the evaporation cylinder 1.

[0049] The humidifying device further includes a water replenishment mechanism, and the water outlet of the water replenishment mechanism is communicated with the evaporation cylinder 1. When the water level in the evaporation cylinder 1 is lower than the preset range, the water replenishment mechanism can replenish water into the evaporation cylinder 1.

[0050] Specifically, the water replenishment mechanism includes a water replenishment pipe 8 and a water replenishment valve. One end of the water replenishment pipe 8 is communicated with an external water source, and the other end is communicated with the evaporation cylinder 1. The water replenishment valve is arranged on the water replenishment pipe 8 and electrically connected to the water level detection mechanism 7. When the water level in the evaporation cylinder 1 is lower than the preset range, the water replenishment valve is opened, and the water replenishment pipe 8 introduces the external water source into the evaporation cylinder 1 for water replenishment. When the water level in the evaporation cylinder 1 reaches the preset range, the water replenishment valve is closed, and the water replenishment to the evaporation cylinder 1 is stopped.

[0051] The water replenishment pipe 8 can be communicated with a water tank or an external water source. Preferably, the water tank is a water dispenser water tank, that is, clean water is replenished into the evaporation cylinder 1, thus avoiding problems such as bacteria existing when using defrosting water in the prior art and affecting the safety of food in the refrigeration equipment.

[0052] Based on the above humidifying device, in the preferred embodiment 1 of the present invention, a control method for the humidifying device is further provided. Figure 6 An optional flowchart showing this method is as Figure 6 shown. This method includes the following steps S602 - S606:

[0053] S602: Monitor the water level of the evaporation cylinder;

[0054] S604: Determine the current working state of the humidifying device according to the water level of the evaporation cylinder;

[0055] S606: Control the operation of the water level regulating device according to the current working state of the humidifying device.

[0056] In the above-described embodiment, a precise humidification device control solution is provided. By monitoring the water level in the evaporation cylinder, the current working state of the humidification device is determined, and then the operation of the water level adjustment device is controlled according to the current working state of the humidification device to precisely and dynamically control the humidification device, improving the accuracy of the humidification device control. Moreover, there is no need for manual frequent operation of the humidification device, effectively improving the user experience and the operating efficiency of the humidification device.

[0057] The above water level adjustment device is connected to the evaporation cylinder and the water storage cylinder, and is used to add water to the evaporation cylinder and / or to the water storage cylinder; the water level adjustment device includes the above-mentioned negative pressure mechanism, the negative pressure mechanism is arranged on the water storage cylinder, and the negative pressure mechanism can generate negative pressure in the water storage cylinder for adding water to the water storage cylinder; and a water replenishing mechanism, the water outlet of the water replenishing mechanism is connected to the evaporation cylinder for adding water to the evaporation cylinder.

[0058] As described above, the current working state of the humidification device at least includes: humidification state, evaporation cylinder water adding state, water storage cylinder water adding state, and water shortage state; further, determining the current working state of the humidification device according to the water level in the evaporation cylinder includes: when the water level in the evaporation cylinder is less than the first preset value, for example, 3 mm, determining that the current working state of the humidification device is the water shortage state; when the water level in the evaporation cylinder is greater than the second preset value, for example, 30 mm, determining that the current working state of the humidification device is the evaporation cylinder water adding state; where the first preset value is less than the second preset value; when the water level in the evaporation cylinder is greater than or equal to the first preset value and less than or equal to the second preset value, determining that the current working state of the humidification device is the humidification state, or the evaporation cylinder water adding state, or the water storage cylinder water adding state.

[0059] Specifically, determining that the current working state of the humidification device is the humidification state, or the evaporation cylinder water adding state, or the water storage cylinder water adding state includes: judging whether the negative pressure mechanism is operating; if so, determining that the current working state of the humidification device is the water storage cylinder water adding state; otherwise, further judging whether the water replenishing mechanism is opened, if it is opened, determining that the current working state of the humidification device is the evaporation cylinder water adding state, if it is not opened, determining that the current working state of the humidification device is the humidification state.

[0060] When the current working state of the humidification device is the water shortage state, the water replenishing mechanism is opened to add water to the evaporation cylinder; after opening the water replenishing mechanism to add water to the evaporation cylinder, it further includes: detecting whether the water level in the evaporation cylinder reaches the third preset value; if so, controlling the water replenishing mechanism to close; that is, monitoring the water level during water replenishment to avoid water overflow from the evaporator. At the same time, after the water replenishing mechanism is closed, controlling the negative pressure mechanism to generate negative pressure in the water storage cylinder, so that the water in the evaporation cylinder enters the water storage cylinder under the action of negative pressure to add water to the water storage cylinder, that is, after the evaporation cylinder water adding is completed, adding water to the water storage tank.

[0061] When the current working state of the humidifying device is the state of adding water to the evaporation cylinder, the water supply mechanism is controlled to close; when in the state of adding water to the evaporation cylinder, that is, when the water level in the evaporation cylinder is greater than the second preset value, the water valve needs to be closed in time to prevent water from overflowing.

[0062] When the current working state of the humidifying device is the state of adding water to the water storage cylinder, the water level in the evaporation cylinder is monitored. When the water level in the evaporation cylinder is less than the third preset value, the negative pressure mechanism is controlled to stop operating; where the third preset value is greater than the first preset value and less than the second preset value; during the process of adding water to the water storage cylinder, the water level situation in the evaporation cylinder is monitored in real time. When the water level in the evaporation cylinder is lower than the third preset value, for example, 4 mm, the water storage is completed and the servo motor stops running. When the water level in the evaporation cylinder is higher than 4 mm, the water storage operation continues.

[0063] When the current working state of the humidifying device is the humidifying state, the water level in the evaporation cylinder is monitored. When the water level in the evaporation cylinder is less than the first preset value, the humidifying device is controlled to enter the state of adding water to the water storage cylinder. When it is detected that the water level in the evaporation cylinder is lower than the first preset value, at this time the humidifying device is in a water shortage state, the water valve is immediately opened, and the water level is monitored in real time.

[0064] In addition, after the water supply mechanism is opened to add water to the evaporation cylinder, it further includes: obtaining the opening time of the water supply mechanism; when the opening time is greater than the preset time, an alarm message is sent, and the alarm message is used to prompt that the water supply device of the water supply mechanism needs to add water. That is, too long water addition time indicates that the water tank is short of water and it is necessary to remind the user or the system to add water to the water tank to ensure the normal water use of the humidifying device.

[0065] In the preferred embodiment 1 of the present invention, another method for controlling a humidifying device is further provided. Specifically, Figure 7 An optional flowchart showing the method is as Figure 7 shown. The method includes the following steps S702 - S724:

[0066] S702: Start;

[0067] S704: Read the water level height K of the evaporation cylinder; the water level detector in the evaporation cylinder reads the water level data and feeds it back to the main control;

[0068] S706: (K, 3, 30); that is, whether K is within the range of 3 - 30 (mm); if K > 30, go to step S714, if K < 3, go to step S708;

[0069] S708: Open the water valve; when it is detected that the water level in the evaporation cylinder is lower than 3 mm, the humidifying device is in a water shortage state, the water valve is immediately opened, and the water level height is monitored in real time;

[0070] S710: Determine whether the opening time of the water valve is greater than 1 minute; if so, go to step S712, otherwise, go to step S704;

[0071] S712: Activate the alarm for 1 minute; when the opening time of the water valve is greater than 1 minute, the main control will issue a 1-minute alarm to remind that the water tank needs to be refilled;

[0072] S714: Close the water valve; when the water level is higher than 30 mm, it is in the state of adding water to the evaporation cylinder, and the water valve needs to be closed in time to prevent water from overflowing;

[0073] S716: Reset the servo motor; after the water addition to the evaporation cylinder is completed, the servo motor resets to control the piston to move to the lowest end of the water storage cylinder to remove the excess air in the water storage cylinder;

[0074] S718: The servo motor works for water storage; after the servo motor, then control the piston to move up to complete the water storage process;

[0075] S720: Read the water level data; during the water storage in the water storage cylinder, monitor the water level situation in the evaporation cylinder in real time;

[0076] S722: Determine whether the water level in the evaporation cylinder > 4 mm holds; if so, go to step S720, otherwise, go to step S724;

[0077] S724: The servo motor stops rotating; when the water level in the evaporation cylinder is lower than 4 mm, the water storage is completed and the servo motor stops running. When the water level in the evaporation cylinder is higher than 4 mm, the water storage action continues.

[0078] The above humidifying device control solution controls the opening and closing timing of the water valve, collects the information of the water level detector, feeds back and controls the operation of the servo motor, completes one cycle of operation of the humidifying device, dynamically controls the water level, ensures that the evaporation efficiency is in the optimal state, avoids frequent manual water addition by the user, and improves the user experience and the operation efficiency of the humidifying device.
