Description

Technical Field

[0001] This application relates to the field of air cooler technology, and in particular to a water tank, an air cooler, and a control method and device thereof. Background Technology

[0002] Air evaporators are direct evaporative cooling and humidifying devices. Their working principle involves a water pump delivering water from a tank to a cooling pad. Air passing through the cooling pad carries moisture, and the evaporation of water absorbs heat, achieving cooling and humidification. However, existing air evaporators use conventional water tanks, and most internal components can only detect low water levels, not critical levels. This leads to repeated empty pumping, wasted energy, and noise. Furthermore, when the water level is critical, the pump cannot deliver enough water to the cooling pad. Additionally, existing water tanks rely solely on ice packs for cooling, which is limited, and residual water in the pump and internal components is not treated after use, preventing the cooling pad from drying effectively. Summary of the Invention

[0003] To address the aforementioned problems, this application provides a water tank, a cooler, and a control method and device thereof. By setting the structure of the water tank, it is possible to detect whether the water in the tank has reached a critical water level. When the water in the tank is detected to have reached the critical water level, the water pump can be controlled to stop, thereby avoiding repeated empty pumping.

The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0044] If the application documents contain similar descriptions such as "first, second, third", the following explanation shall be added: In the following description, the terms "first, second, third" are used only to distinguish similar objects and do not represent a specific order of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0046] Based on the problems existing in related technologies, this application provides a water tank, which includes: a water tank body 1, a water pump 2, a water supply pipe 3, a float ring 4, a first detection component 5, and a second detection component 6. The water pump 2 is disposed within the water tank body 1. One end of the water supply pipe 3 is connected to the water pump 2, and the other end is connected to a wet curtain. A first limiting part 7 and a second limiting part 8 are provided within the water supply pipe 3, positioned on either side of a critical dry-running position. The float ring 4 is disposed within the water supply pipe 3, between the first limiting part 7 and the second limiting part 8. The first detection component 5 is disposed between the first limiting part 7 and the critical dry-running position. The second detection component 6 is disposed between the critical dry-running position and the second limiting part 8. The first detection component 7 and the second detection component 8 are used to detect the position of the float ring 4.

[0047] In this embodiment, the shape and size of the water tank body can be customized according to the needs of the cooling fan. The water tank body is used to hold water. The water pump is used to input water into the water supply pipe, and the water pump is installed inside the water tank body and located at the bottom.

[0048] In this embodiment, the first limiting part and the second limiting part can be protrusions, which limit the floating ring so that the floating ring can only move between the first limiting part and the second limiting part.

[0049] In this embodiment, the float ring has a central hole. When the water pump inputs water into the water pipe, the water causes the float ring to float. When water is input, the float ring floats towards the first limiting part; if there is no water, the float ring contacts the second limiting part.

[0050] In this embodiment, the critical position for air evacuation can be determined experimentally. The air evacuation threshold corresponds to the critical water level in the water tank.

[0051] In this embodiment, the first detection component and the second detection component can be Hall effect sensors. By setting the first detection component between the first limiting part and the air-drying critical position, and the second detection component between the air-drying critical position and the second limiting part, when the floating ring floats between the first limiting part and the air-drying critical position, the first detection component can obtain a detection signal of the floating ring's position; when the floating ring is between the second limiting part and the air-drying critical position, the second detection component can obtain a detection signal of the floating ring's position.

[0052] In this embodiment, if the detection component does not detect the floating ring, the detection signal can be a low-level signal; if the detection component detects the floating ring, it can output a high-level signal.

[0053] See also Figure 1 In some embodiments, a residual water storage area 10 is provided at the bottom of the water tank body, and the water tank further includes:

[0054] A refrigeration device 9 is disposed at the bottom of the water tank body. The device includes a refrigeration heat sink 91, which is disposed opposite to the residual water storage area 10.

[0055] The third detection component 11 is disposed on the water tank body and is used to detect the amount of water in the residual water storage area 10.

[0056] In this embodiment, the size of the residual water storage area can be set.

[0057] In this embodiment, the cooling device may be a semiconductor refrigeration chip, with one side of the semiconductor refrigeration chip being a cooling chip heat-conducting sheet and the other side of the semiconductor refrigeration chip being a cooling heat sink.

[0058] In this embodiment, a float and a third detection component can be set in the residual water storage area. The third detection component can detect the float to determine whether there is a lot of residual water in the residual water storage area.

[0059] In some embodiments, the water tank body is further provided with a fourth detection component 12, which is used to detect the water volume in the water tank body. The distance between the position of the fourth detection component 12 and the bottom of the water tank body is greater than the distance between the position of the third detection component 11 and the bottom of the water tank body.

[0060] In this embodiment of the application, the fourth detection component can be a Hall effect detection board.

[0061] In some embodiments, the water tank further includes a cooling fan, which is connected to the water supply pipe via a one-way check valve;

[0062] Drain pipe 13, one end of which is connected to water supply pipe 3 and the other end of which is connected to residual water storage area, and a solenoid valve 14 is provided in drain pipe 13.

[0063] In this embodiment, a four-way pipe can be provided, with one port connected to the water supply pipe, one port connected to the water pump outlet, one port connected to the cooling fan, and the last port connected to the solenoid valve for discharging residual water in the water supply pipe.

[0064] This application provides a cooling fan, including: the water tank described in any of the above claims.

[0065] Based on the air cooler provided in the above embodiments, this application provides a control method, the execution subject of which can be an electronic device. The electronic device can be an air cooler, laptop, tablet, desktop computer, set-top box, mobile device (e.g., mobile phone, portable music player, personal digital assistant, dedicated messaging device, portable gaming device), or other types of terminals, or it can be implemented as a server. The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms.

[0066] In some embodiments, the electronic device may be a controller for a cooling fan. The following description uses the application of this control method to chilled water as an example.

[0067] The control method provided in this application can achieve its functions by having the processor of an electronic device call program code, wherein the program code can be stored in a computer storage medium.

[0068] This application provides a control method. Figure 2 This is a schematic diagram illustrating the implementation flow of a control method provided in an embodiment of this application, as shown below. Figure 2 As shown, it includes:

[0069] Step S101: With the humidification mode of the cooling fan turned on and it confirmed that the water tank is not short of water, control the water pump to work and obtain the first detection information of the first detection component and the second detection information of the second detection component.

[0070] In this embodiment of the application, the cooling fan can have multiple working modes, such as humidification mode, normal mode, and cooling and humidification mode.

[0071] In this embodiment, each mode can be activated via a trigger command. Taking the humidification mode as an example, in actual implementation, the trigger command for the humidification mode can be in the form of pressing the physical button of the cooling fan, touching the display screen of the cooling fan, or using voice commands. The trigger command for the drying mode can also be in the form of a command issued through a smart terminal such as a mobile phone, tablet, or smart wearable device, wherein a communication connection is established between the humidification mode and the smart terminal.

[0072] In this embodiment, the electronic device can be communicatively connected to the fourth detection component, and can determine whether the water tank is short of water based on the detection signal from the fourth detection component. When the detection signal is a high-level signal, it can be determined that the water tank itself is not short of water. If the detection signal is a low-level signal, it can be determined that the water tank itself is short of water.

[0073] In this embodiment of the application, when the water tank body is not short of water, the electronic device can send control commands to the water pump to make the water pump start working.

[0074] In this embodiment, after the water pump starts working, it will pump water in and out of the water supply pipe. If the water level in the tank is below the critical level, the water pump can normally deliver water to the evaporative cooling pad, thus achieving humidification mode. However, even if the water tank is not short of water, there may be a situation where the water level in the tank is at the critical level. In this case, if the water pump continues to work, water cannot be delivered to the evaporative cooling pad. If no detection is performed, the water pump will run dry. Therefore, in this embodiment, the electronic device can acquire the first detection information from the first detection component and the second detection information from the second detection component.

[0075] Step S102: Determine whether the water level in the water tank has reached the critical water level based on the first detection information and the second detection information.

[0076] In this embodiment, it can be determined whether the water pump can continuously deliver water to the wet curtain based on the first detection information and the second detection information; it can also be determined whether the water level in the water tank has reached a critical water level based on whether the water pump can continuously deliver water to the wet curtain. Specifically, if the water pump can continuously deliver water to the wet curtain, it is determined that the water level in the water tank is higher than the critical water level; if the water pump cannot continuously deliver water to the wet curtain, it is determined that the water level in the water tank body has reached the critical water level.

[0077] In this embodiment, if both the first detection information and the second detection information are continuously at a high level, it is determined that the water pump can continuously deliver water to the wet curtain. If the first detection signal switches between high and low levels and the second detection signal is at a high level, it is determined that the water pump cannot continuously deliver water to the wet curtain.

[0078] Step S103: When it is determined that the water level in the water tank has reached the critical water level, the water pump is controlled to stop working and an alarm message is output. When the water level in the water tank reaches the critical water level, the water pump cannot deliver water to the wet curtain of the cooling fan through the water pipe.

[0079] In this embodiment of the application, the electronic device can send control commands to the water pump, thereby causing the water pump to stop working.

[0080] In this embodiment, an alarm device can be used to output alarm notification information. This alarm device can be a display screen, a sound playback device, an indicator light, etc. For example, the display screen can output text to display alarm notification information; or a sound playback device can directly output a pre-stored alarm notification sound. Another example is controlling an indicator light to flash.

[0081] In some embodiments, the method further includes:

[0082] After the air cooler is turned on, all other functions of the air cooler will work normally if the humidification function is not activated.

[0083] In some embodiments, the method further includes:

[0084] If the humidification mode of the cooling fan is turned on and it is determined that the water tank is low on water, an alarm signal will be output.

[0085] In some embodiments, the cooling fan includes a cooling device, a cooling fan, and a solenoid valve, which controls the cooling device to operate when the cooling fan is in humidification mode and the water tank is determined to be full.

[0086] In this embodiment of the application, controlling the operation of the refrigeration device can generate cold air, thereby achieving a refrigeration effect.

[0087] In some embodiments, after step S103, the method further includes:

[0088] In step S104, upon receiving a shutdown command for the cooling fan, the refrigeration device is controlled to continue operating, and the solenoid valve is opened and the cooling fan is operated.

[0089] In this embodiment, when the refrigeration device continues to work, the refrigeration heat sink will generate heat, causing the water in the residual water storage area to evaporate. In addition, after the solenoid valve is opened, the water in the water supply pipe will enter the residual water storage area. By controlling the cooling fan to work, the water in the water supply pipe can be dried.

[0090] Step S105: After a preset time, control the cooling fan to turn off.

[0091] In this embodiment of the application, the preset duration can be obtained from experiments. The manufacturer can set the preset duration when the air cooler leaves the factory.

[0092] After a preset time, the water in the residual water storage area and water pipes will evaporate, thus drying these components.

[0093] In this embodiment of the application, the cooling fan can be controlled to turn off.

[0094] Based on the foregoing embodiments, this application provides another control method. When the air cooler is turned on, the entire unit begins to work. The unit first performs a water shortage detection. If the output level signal of the detection board A (same as the fourth detection component in the above embodiments) is low, the controller E (same as the electronic device in the above embodiments) receives the signal from the detection board A and determines that the water level in the water tank is low. Then, the controller E determines whether the circulating air cooler has been turned on in humidification mode by the user. If humidification mode is not turned on, the water pump does not work, and there is no need to issue a water shortage alarm; other functions operate normally. If the user presses to turn on humidification mode, the display panel issues a water shortage alarm (buzzer alarm), and the water pump does not work.

[0095] If the output signal of detection board A is high (where low level is represented by 0 and high level by 1), then controller E determines that the water level in the tank is not low and the humidification function is activated. Simultaneously with activating the water pump, it is also necessary to check detection board B (same as the first detection component in the above embodiment) and detection board C (same as the second detection component in the above embodiment). Similarly, the input signals are processed multiple times within a cycle. If the level signal received by the main control chip of controller E is consistently 11 within the cycle, the water pump continues to operate normally. If the level signal received by the main control chip of controller E is 10 and 11 repeatedly within the cycle, it indicates that the water level in the tank is critical and the water volume cannot meet the normal water supply requirements for the wet curtain. The main control chip of controller E then drives the water pump's I / O port to output a stop signal; the water pump stops running dry and issues an alarm indicating insufficient water level.

[0096] After the user presses the power button, the machine shuts down after a delay (the delay time can be set according to actual needs). During this time, the water pump is turned off first, while the thermoelectric cooler (same as the cooling device in the above embodiment) continues to work. Then, the solenoid valve is opened to drain the water in the water pipe into the residual water treatment area, where the heat generated by the thermoelectric cooler evaporates the residual water. After the water in the water pipe is drained, the exhaust fan is turned on to blow hot air into the water pipe and the water pump, drying these components. After completing the above steps, the entire machine is shut down and returns to standby mode.

[0097] The method provided in this application uses commonly available detection elements and the working principle and characteristics of semiconductor cooling chips to accurately determine the critical water level in the water tank, solve the problem of dry pumping, and take into account the problem of residual water in the water pump delivery pipe after the pump stops working, which significantly improves the user experience.

[0098] Based on the foregoing embodiments, this application provides a control device. The modules and units included in the device can be implemented by a processor in a computer device; of course, they can also be implemented by specific logic circuits. In the implementation process, the processor can be a central processing unit (CPU), a microprocessor (MPU), a digital signal processor (DSP), or a field programmable gate array (FPGA), etc.

[0099] This application provides a control device, which includes:

[0100] The first control module is used to control the water pump to work when the humidification mode of the air cooler is turned on and it is determined that the water tank is not short of water, and to acquire the first detection information of the first detection component and the second detection information of the second detection component.

[0101] The determining module is used to determine whether the water level in the water tank has reached the critical water level based on the first detection information and the second detection information;

[0102] The second control module is used to control the water pump to stop working and output an alarm message when it is determined that the water level in the water tank has reached the critical water level. When the water level in the water tank reaches the critical water level, the water pump cannot deliver water to the wet curtain of the cooling fan through the water pipe.

[0103] In some embodiments, determining whether the water level in the water tank body has reached a critical water level based on the first detection information and the second detection information includes:

[0104] Based on the first detection information and the second detection information, determine whether the water pump can continuously deliver water to the wet curtain;

[0105] The water level in the water tank is determined to be above the critical water level based on whether the water pump can continuously deliver water to the wet curtain. If the water pump can continuously deliver water to the wet curtain, the water level in the water tank is determined to be above the critical water level. If the water pump cannot continuously deliver water to the wet curtain, the water level in the water tank is determined to have reached the critical water level.

[0106] In some embodiments, the cooling fan includes: a cooling device, a cooling fan, and a solenoid valve. When the cooling fan is in humidification mode and the water tank is determined to be full, the control device controls the cooling device to operate. The control device is further configured to:

[0107] Upon receiving a shutdown command for the cooling fan, the system controls the refrigeration unit to continue operating, and controls the solenoid valve to open and the cooling fan to operate.

[0108] After a preset time, the cooling fan is turned off.
