Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
The mobile air conditioner includes shell subassembly, evaporimeter, condenser, compressor, exhaust subassembly and other electronic spare parts etc. and the evaporimeter, condenser and compressor all set up inside shell subassembly for the mobile air conditioner forms an integral type air conditioner from this, in other words, the mobile air conditioner has cancelled traditional air conditioner and has divided into the setting mode of interior machine and outer machine, integrates traditional interior machine and outer machine as an organic whole, can make things convenient for the mobile air conditioner to place the setting in the indoor space optional position. The exhaust assembly is led out of the shell assembly so as to conveniently guide out the air flow passing through the condenser outdoors.
In the prior art, electronic components inside a mobile air conditioner generate a lot of heat during operation, for example, a controller in the mobile air conditioner. The controller needs a sealed design and has poor heat dissipation. When the operation frequency of the compressor is too high, the current is too large or the use environment is worse, the controller can generate more heat, if the controller cannot be subjected to cooling treatment, the temperature rise of the electric device can reach the limit, and the reliability cannot be ensured. In order to ensure reliability, frequency limiting protection is often performed, but the performance of an air conditioner is affected, and the user experience is affected. At present, most of variable frequency mobile air conditioners are air-cooled heat dissipation designs, and the controller is poor in heat dissipation effect and has great limitation on air conditioning performance.
In order to improve the above technical problems, in other words, in order to improve the technical problem of poor heat dissipation effect of the controller in the prior art, the present application provides a mobile air conditioner, and a cooling control method and device applied to the mobile air conditioner.
The mobile air conditioner comprises a main body assembly, an evaporator, a condenser and a controller. The evaporator, condenser and controller are all disposed within the body assembly, and the evaporator is located above the condenser and controller. It should be noted that, in order to make the mobile air conditioner operate normally and have a general function, a compressor, an expansion valve, and other electronic components are further disposed in the main body assembly, which will not be described herein. In addition, the main body component is internally provided with a mounting bracket, a first water discharge component and a second water discharge component. Wherein the evaporator is mounted on the mounting bracket and condensed water generated by the evaporator during operation may drip on the mounting bracket, in other words, the mounting bracket may be used for receiving condensed water generated by the evaporator. The first drainage assembly and the second drainage assembly are both connected to the mounting bracket, and the first drainage assembly and the second drainage assembly are used for guiding out condensed water received on the mounting bracket. The first drainage assembly is arranged corresponding to the condenser and used for guiding condensed water to flow to the condenser so that the condensed water exchanges heat with the condenser, and therefore the heat exchange efficiency of the condenser can be improved, and the energy efficiency of the mobile air conditioner is improved. The second drainage assembly is connected with the controller and used for guiding condensed water to flow to the controller so as to cool the controller, thereby achieving the effect of cooling and radiating the controller and ensuring the controller to stably operate. Based on the above, the technical problem of poor heat dissipation effect of the controller in the prior art can be solved by arranging the second water draining component.
In the mobile air conditioner, the condensed water generated by the evaporator in the running process can be received by the mounting bracket, and the condensed water received on the mounting bracket can be discharged to the condenser by the first drainage assembly, so that the condensed water exchanges heat with the condenser, and the heat exchange efficiency of the condenser can be improved; in addition, the condensed water can be discharged to the controller through the second water discharging assembly so as to cool the controller, thereby achieving the purpose of reducing the temperature of the controller, and further solving the technical problem that the heat dissipation effect of the controller in the prior art is poor. Of course, the controller may be used to control the water discharge amount of the first water discharge assembly and the water discharge amount of the second water discharge assembly, thereby controlling the amount of condensed water guided to the controller by the second water discharge assembly according to actual conditions, so as to provide an effective cooling effect to the controller, and improving the stability of the controller.
In addition, the first drainage assembly and the second drainage assembly are electrically connected with the controller, the controller can control the drainage amount of the first drainage assembly, and the controller can also control the drainage amount of the second drainage assembly; the cooling effect provided to the controller can be adjusted according to the actual situation by controlling the water discharge amount of the first water discharge assembly and the water discharge amount of the second water discharge assembly by the controller. When the controller needs a stronger cooling effect, the controller can control the water discharge amount of the second water discharge assembly to be increased so as to sufficiently cool the controller and ensure the stable operation of the controller; when the demand of the controller for the cooling effect is small, the controller may control the drain amount of the second drain assembly to be reduced, and may reduce the amount of condensed water used to cool the controller, thereby ensuring the amount of condensed water flowing to the condenser, thereby ensuring the heat exchange efficiency of the condenser. It is worth noting that, due to the limited condensed water generated by the evaporator, the controller controls the water discharge amount of the first water discharge assembly to be reduced while controlling the water discharge amount of the second water discharge assembly to be increased; similarly, the water discharge amount of the first water discharge assembly is controlled to be increased while the water discharge amount of the second water discharge assembly is controlled to be decreased.
It should be noted that, under the general condition, when the mobile air conditioner is just started or the starting time is shorter, the running time of the controller is shorter, so that the heat generated by the controller is less; or, under the condition that the temperature of the environment where the mobile air conditioner is positioned is lower, the heat dissipation effect of the controller is better. In both cases, the controller can operate normally, so that the controller does not need to be provided with a cooling effect. Based on this, in some embodiments of the present application, the second drain assembly may be set to a normally closed state, and in case the controller needs cooling, the controller may control the second drain assembly to be opened to guide condensed water to flow to the controller. In addition, in order to ensure that the condenser can exchange heat effectively, thereby improving the energy efficiency of the mobile air conditioner, in some embodiments of the present application, the first drainage assembly is set to be in a normally open state, in other words, in general, condensed water generated by the evaporator is guided to flow to the condenser by the first drainage assembly. It should be understood that in other embodiments of the present application, the first drain assembly and the second drain assembly may be disposed in other manners, for example, the opening and closing of the first drain assembly and the second drain assembly are completely controlled by the controller; or the second drain assembly is opened with a preset amount of drain water, etc.
In some embodiments of the present application, in order to facilitate drainage of condensate received by the mounting bracket, the mounting bracket may optionally be provided with a plurality of first drain holes and a plurality of second drain holes. The first water draining assemblies are used for guiding out condensed water through at least one first water draining hole; the plurality of second drain holes are all connected with the second drain assembly, and the second drain assembly is used for leading out the comdenstion water through at least one second drain hole. In other words, the first drain assembly may draw condensed water from the at least one first drain hole and direct the condensed water to the condenser; the second drain assembly may direct condensed water from the at least one second drain hole and to the controller.
In order to control the water discharge amount of the first water discharge assembly and the water discharge amount of the second water discharge assembly, the controller may control the first water discharge assembly to open the number of the first water discharge holes to control the water discharge amount of the first water discharge assembly; similarly, the controller can control the number of the second water discharge holes opened by the second water discharge assembly to control the water discharge amount of the second water discharge assembly. That is, the greater the number of first drain holes opened by the first drain assembly, the greater the amount of water drained by the first drain assembly, and the lesser the number of first drain holes opened by the first drain assembly, the lesser the amount of water drained by the first drain assembly; similarly, the larger the number of second drain holes opened by the second drain assembly, the larger the drainage amount of the second drain assembly, and the smaller the number of second drain holes opened by the second drain assembly, the smaller the drainage amount of the second drain assembly. In addition, because the condensed water generated by the evaporator is limited, when the second water drain holes with the preset number are controlled to be opened, the first water drain holes with the corresponding number are synchronously closed; similarly, when the second water drain holes with the preset number are controlled to be closed, the first water drain holes with the corresponding number are synchronously opened.
It should be noted that, in some embodiments of the present application, the first drainage assembly may be configured as a stop valve for opening or closing the first drainage hole, and of course, the first drainage assembly may be configured as other switch structures. The stop valve is electrically connected with the controller, and the controller can control the opening and closing of the stop valve so as to realize the opening and closing of the first drain hole. Based on this, the first drain hole may be provided above the condenser, and condensed water may directly fall out of the first drain hole in case that the controller controls the shut-off valve to be opened, so that the condensed water falls onto the condenser. Wherein setting the first drain assembly to a normally open state means that the shut-off valve is normally in an open state so that condensed water can fall onto the condenser through the first drain hole.
Additionally, the second drain assembly may include a conduit and an on-off valve; the conduit may be a multi-access conduit, each access end being connected to a second drain hole to obtain condensate from the second drain hole. And each access end is provided with a switch valve, so that the second drain hole can be opened and closed by opening and closing the switch valve. In order to facilitate the cooling of the controller, the guide pipe passes through the controller, and the condensed water can exchange heat with the controller in the flowing process of the guide pipe, thereby realizing the purpose of cooling the controller. The plurality of switch valves are all electrically connected with the controller, and the controller can control the opening and closing of the switch valves to realize the adjustment of the quantity of the conducted second water discharge holes, so that the water discharge quantity of the second water discharge assembly can be adjusted. The second drainage component is set to be in a normally closed state, namely, the normally-closed state of the switch valve is adopted to prevent condensed water from being led out through the second drainage hole, so that in a general state, enough condensed water can be ensured to flow to the condenser, the heat exchange efficiency of the condenser is improved, and the energy efficiency of the mobile air conditioner is improved.
Of course, in other embodiments of the present application, the adjustment manner of the drainage amount of the first drainage assembly is not limited to the adjustment by adjusting the number of openings of the first drainage hole. For example, the first drain assembly may include a drain pipe that may draw condensed water from the mounting bracket to guide the condensed water to the condenser, and a flow valve that may adjust a flow rate of the drain pipe so that a drainage amount of the first drain assembly may be adjusted; in other words, the opening degree of the drain pipe may be adjusted by the flow valve to achieve adjustment of the drainage amount of the first drainage assembly. Similarly, in other embodiments, the second drain assembly may also be configured with a drain pipe and a flow valve, so that the opening of the drain pipe is adjusted by the flow valve to adjust the drainage of the second drain assembly. For another example, the first drain assembly may include a drain pipe and a water pump, the amount of water discharged by the drain pipe being adjusted by adjusting an operating power of the water pump, thereby effecting adjustment of the amount of water discharged by the first drain assembly; similarly, in other embodiments of the present application, the second water discharge assembly may also be configured by a water discharge pipe and a water pump, so as to adjust the water discharge amount of the second water discharge assembly by adjusting the operation power of the water pump.
Optionally, in order to ensure that condensed water flows to the condenser, thereby improving the heat exchange efficiency of the condenser, in some embodiments of the present application, the number of first drain holes is smaller than the number of second drain holes; in other words, the number of the first drain holes formed in the mounting bracket is smaller than the number of the second drain holes formed in the mounting bracket. Thereby, it is ensured that condensed water is guided to the condenser, thereby ensuring heat exchange efficiency of the condenser. In some embodiments of the present application, the number of the first drain holes ranges from 1 to 7, in other words, the number of the first drain holes may be 1, 2, 3, 4, 5, 6, 7, or the like. In addition, the number of the second drain holes is in the range of 2 to 8, in other words, the number of the second drain holes may be 2, 3, 4, 5, 6, 7, 8, or the like.
Referring to fig. 1, a water receiving tray 10 is further disposed at the bottom of the main body assembly, and the water receiving tray 10 is used for receiving condensed water. In other words, after the condensed water is guided to the condenser or the controller, the condensed water flows into the water receiving tray 10, which can prevent the condensed water from being lost, and also prevent the condensed water from flowing into the room to cause a decrease in the indoor cleanliness. Meanwhile, the condensed water is received by the water receiving disc 10, and can be recycled.
Wherein, the water receiving tray 10 is provided with a first water tank 11 and a second water tank 12 which are mutually communicated. The first water tank 11 is disposed corresponding to the first drain assembly to receive condensed water of the first drain assembly directed to the condenser. In other words, the first water tank 11 is disposed below the first drain hole, and in the case where condensed water is led out in the first drain hole, the condensed water falls onto the condenser, and after passing through the condenser, the condensed water falls into the first water tank 11. Naturally, it is also possible to consider that the first water tank 11 is provided below the condenser, and after the condensed water exchanges heat with the condenser, the condensed water drops from the condenser into the first water tank 11. The second water tank 12 is disposed corresponding to the second drain assembly to receive condensed water from the second drain assembly directed to the controller. In other words, the conduit in the second drain assembly is introduced into the second water tank 12 after passing through the controller such that the condensed water after cooling the controller is directed to the second water tank 12. Because the temperature of the condensed water exchanging heat with the condenser is lower than that of the condensed water of the cooling controller, the condensed water exchanging heat with the condenser is distinguished from the condensed water of the cooling controller by arranging the first water tank 11 and the second water tank 12, and the condensed water with lower temperature can be distinguished from the condensed water with higher temperature, so that the condensed water with higher temperature is convenient for evaporating and absorbing heat, the heat exchange efficiency of the condenser is improved in an auxiliary way, and the condensed water with lower temperature can be reused for cooling and radiating of the controller.
Optionally, the bottom wall of the first water tank 11 is lower than the bottom wall of the second water tank 12. Based on this, the water in the first water tank 11 and the second water tank 12 can be distinguished, and the second water tank 12 can be lifted, so that the evaporation of condensed water can be promoted to absorb the heat of the space where the condenser is located, thereby promoting the improvement of the heat exchange efficiency of the condenser.
The mobile air conditioner may further include a pumping assembly 20 and a water pumping assembly 30. The water pumping assembly 20 is arranged in the first water tank 11, and the water pumping assembly 20 is connected with the controller; the water pumping assembly 20 is used for pumping condensed water in the first water tank 11 to guide the condensed water to the controller. In other words, the water pumping assembly 20 may pump out the condensed water having a lower temperature in the first water tank 11 to be directed to the controller, thereby ensuring that the controller can be cooled effectively. The water pumping assembly 20 comprises a water pump and a water pipe, the water pump is arranged at the bottom of the first water tank 11, and the water pipe is connected with the water pump; the water pump may guide the water in the first water tank 11 to the controller through the water pipe. In addition, a water-beating assembly 30 is provided in the second water tank 12 for beating water to spray condensed water onto the condenser. Wherein, be provided with water-beating wheel and motor in the subassembly 30 of beating water, motor drive water-beating wheel rotates in second basin 12, and at the in-process that the wheel rotated of beating water, the water-beating wheel can hit the condensate water in the second basin 12, makes the comdenstion water drench on the condenser from this to improve the heat exchange efficiency of condenser.
It should be noted that the water pump is electrically connected to the controller, and the controller may control the operation of the water pump to pump condensed water to the controller. In some embodiments, the water pump is in an off state with less heat generated by the controller or the controller in an environment that may be such that the controller is actively dissipating heat. Similarly, the motor in the water pumping assembly 30 can also be electrically connected with a controller, and the controller can control the running power of the motor, so as to control the water pumping amount and adjust the amount of condensed water sprayed onto the condenser.
In order to conveniently adjust the cooling effect on the controller, the mobile air conditioner also comprises a temperature detection device and a current detection device. The temperature detection device is arranged on the main body assembly and is used for detecting the temperature of the environment where the mobile air conditioner is located. The current detection device is arranged on the controller and is used for detecting the current of the controller. In addition, the temperature detection device and the current detection device are both connected with the controller, and the controller can receive the environmental temperature value detected and sent by the temperature detection device, and the environmental temperature value represents the temperature of the environment where the mobile air conditioner is positioned; the controller may also receive a current value detected and emitted by the current detection means, which current value is indicative of the current at which the controller is operating.
It should be noted that the environmental temperature value may reflect the temperature of the environment where the mobile air conditioner is located, so as to determine whether the environment where the controller is located can provide a good heat exchange environment for the controller. The current value may reflect the operation of the controller, and if the current value is larger, the heat generated by the controller is larger, and if the current value is smaller, the heat generated by the controller is smaller.
It should be appreciated that in other embodiments of the present application, the amount of heat generated by the controller may be determined in other ways instead of using a way to detect the controller current; for example, by detecting the power at which the controller operates, or directly detecting the heat generated by the controller, or detecting the operating time of the controller, etc.
In addition, the controller may be an integrated circuit chip with signal processing capabilities. The controller may be a general-purpose processor, including a central processing unit (Central Processing Unit, CPU), a single-chip microcomputer, a micro-control unit (Microcontroller Unit, MCU), a complex programmable logic device (Complex Programmable Logic Device, CPLD), a Field-programmable gate array (Field-Programmable Gate Array, FPGA), an application specific integrated circuit (Application Specific Integrated Circuit, ASIC), an embedded ARM, or other chips, and may implement or execute the methods, steps, and logic blocks disclosed in the embodiments of the present invention.
In a possible implementation manner, the air conditioner may further include a memory, where the memory is used to store program instructions that may be executed by the controller, for example, the cooling control device provided in the embodiment of the present application includes at least one cooling control device that may be stored in the memory in a form of software or firmware. The Memory may be a stand-alone external Memory including, but not limited to, random access Memory (Random Access Memory, RAM), read Only Memory (ROM), programmable Read Only Memory (Programmable Read-Only Memory, PROM), erasable Read Only Memory (Erasable Programmable Read-Only Memory, EPROM), electrically erasable Read Only Memory (Electric Erasable Programmable Read-Only Memory, EEPROM). The memory may also be provided integrally with the controller, e.g. the memory may be provided integrally with the controller in the same chip.
Based on the above provided mobile air conditioner, in order to improve the technical problem that the heat dissipation effect of the controller in the mobile air conditioner is poor, the application also provides a cooling control method, and the controller can execute the cooling control method to improve the technical problem that the heat dissipation effect of the controller is poor.
Referring to fig. 2, the cooling control method includes:
step S10, receiving an ambient temperature value.
And step S20, if the environmental temperature value is smaller than or equal to the first set target value, controlling the first water draining component to be opened and controlling the second water draining component to be closed.
When the environmental temperature value is smaller than or equal to the first set target value, the temperature of the environment where the mobile air conditioner is located is lower, the spontaneous radiating effect of the controller can meet the radiating requirement of the controller, and the controller can normally operate, so that the second drainage assembly can be closed, and the controller spontaneously radiates and cools; meanwhile, the first drainage component is opened, so that condensed water can flow to the condenser, the heat exchange efficiency of the condenser is improved, and the energy efficiency of the mobile air conditioner is improved.
It should be noted that, in the embodiment of the present application, controlling the first drain assembly to open refers to controlling the first drain assembly to open all the first drain holes by the controller, that is, controlling the stop valve to open all the first drain holes by the controller. Similarly, controlling the second drain assembly to close refers to the controller controlling the second drain assembly to close all of the second drain holes, i.e., the controller controlling all of the on-off valves to close all of the second drain holes.
It should be understood that, in other embodiments of the present application, when the first drain assembly is configured by a drain pipe and a flow valve, the controller controlling the first drain assembly to be opened refers to controlling the flow valve to fully open the drain pipe, that is, guiding condensed water at a maximum opening degree of the drain pipe. Similarly, when the second drain assembly is configured with the drain pipe and the flow valve, the controller controlling the second drain assembly to close refers to the controller controlling the flow valve to completely close the drain pipe. In addition, when the first drainage assembly adopts the setting mode of drain pipe and water pump, control first drainage assembly opens and refers to, control water pump with the gear of predetermineeing open can, should predetermineeing the gear only need satisfy can last effectual acquisition installing support on the comdenstion water, avoid the water pump idle running can. Similarly, when the second water draining assembly adopts the arrangement mode of the water draining pipe and the water pump, controlling the second water draining assembly to be closed refers to controlling the water pump to be closed.
Alternatively, in an embodiment of the present application, in order to ensure that the controller can effectively perform self-heat dissipation without opening the second drain assembly, the value range of the first set target value may be 16 ℃ to 25 ℃, in other words, the value of the first set target value may be 16 ℃, 17 ℃, 18 ℃, 19 ℃, 20 ℃, 21 ℃, 22 ℃, 23 ℃, 24 ℃, 25 ℃, or the like.
Step S30, if the environmental temperature value is greater than the first set target value, receiving a current value.
When the environmental temperature value is greater than the first set target value, it indicates that the environmental temperature affects the self-heat dissipation of the controller, and at this time, it is required to determine whether the controller needs auxiliary heat dissipation according to the current value of the controller, that is, determine whether the controller needs to turn on the second water draining assembly to assist the heat dissipation of the controller. Of course, in other embodiments of the present application, the power value or the emitted heat value of the controller may also be used to determine whether the controller needs auxiliary heat dissipation.
And S40, adjusting the water discharge amount of the first water discharge assembly and the water discharge amount of the second water discharge assembly according to the numerical interval where the current value is located.
In the embodiment of the application, the amount of heat generated by the controller can be judged through the current value of the controller, and based on the amount of heat, the cooling amount required by the controller can be judged under the condition that the ambient temperature is greater than the first set target value, so that the water discharge of the second water discharge assembly of the first water discharge assembly is conveniently controlled.
Optionally, in an embodiment of the present application, the controller adjusts the drainage amount of the first drainage assembly by controlling the first drainage assembly to open or close the first drainage hole, and the controller adjusts the drainage amount of the second drainage assembly by controlling the second drainage assembly to open or close the second drainage hole, based on which, referring to fig. 3, step S40 may include:
Step S41, if the current value is greater than or equal to the first preset current value and less than the second preset current value, controlling the first drainage assembly to close the first drainage holes of the first preset number, and controlling the second drainage assembly to open the second drainage holes of the first preset number.
Step S41 may also be regarded as controlling the first drain assembly to close the first preset number of first drain holes and controlling the second drain assembly to open the first preset number of second drain holes when the current of the controller reaches or exceeds the first preset current value and is not higher than the second preset current value.
Under the condition that the current of the controller is larger than or equal to a first preset current value and smaller than a second preset current value, the controller generates more heat, and under the condition that the ambient temperature is larger than a first set target temperature, the spontaneous heat dissipation of the controller can not meet the heat dissipation requirement of the controller, based on the heat dissipation requirement, the first water drain hole of the closing part of the first water drain assembly is controlled, and the second water drain hole of the opening part of the second water drain assembly is controlled, the heat dissipation effect provided for the controller can be improved, and therefore stable operation of the controller is ensured.
Alternatively, the value range of the first preset current value may be 1A to 10A, in other words, the value of the first preset current value may be 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A, or the like. In addition, the value range of the second preset current value may be 1A to 12A, in other words, the value of the second preset current value may be 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A, 11A, 12A, or the like.
Alternatively, to ensure that a sufficient cooling effect can be provided to the controller, the first preset number of values may be in the range of 2-5, in other words, the first preset number of values may be 2, 3, 4, 5, etc.
Step S42, if the current value is greater than or equal to the second preset current value and less than the third preset current value, controlling the first drainage assembly to close the second preset number of first drainage holes, and controlling the second drainage assembly to open the second preset number of second drainage holes.
Wherein the second preset number is greater than the first preset number.
It should be noted that, in step S42, controlling the first drain assembly to close the second preset number of the first drain holes refers to controlling the total number of the first drain assemblies to close the first drain holes to the second preset number, and in the case of step S41, the controller may control the number of the first drain assemblies to close the first drain holes to be the difference between the first preset number and the second preset number. Similarly, controlling the second drain assembly to open the second preset number of second drain holes refers to controlling the total number of the second drain assemblies to open the second drain holes to be the second preset number, and in the case based on step S41, the controller may control the number of the second drain assemblies to open the second drain holes to be the difference between the first preset number and the second preset number.
Step S42 may also be regarded as that, when the current value of the controller reaches or exceeds the second preset current value and does not reach the third preset current value, the controller controls the first drain assembly to close the second preset number of the first drain holes, and the controller controls the second drain assembly to open the second preset number of the second drain holes.
In other words, the increase of the current value of the controller from the first preset current value to the second preset current value to the third preset current value indicates that the heat generated by the controller increases, and therefore, the number of the second drain holes needs to be increased, based on which the number of the second drain holes is controlled to be increased to the second preset number, thereby improving the cooling effect on the controller.
Alternatively, the second preset number of values may be in the range of 3-7, in other words, the second preset number of values may be 3, 4, 5, 6, 7, or the like. In addition, the value range of the third preset current value may be 1A to 14A, in other words, the value of the third preset current value may be 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A, 11A, 12A, 13A, 14A, or the like.
It should be noted that, in some embodiments of the present application, the sum of the first preset number and the second preset number is smaller than the number of the second drain holes. It is thereby ensured that the condensate directed to the condenser has sufficient condensate, so that the condenser is ensured to be able to exchange heat effectively, in order to increase the energy efficiency of the mobile air conditioner.
In the case where the conditions of any one of the steps are satisfied, the corresponding step may be executed without limitation to the order of the steps S41 and S42.
It should be noted that, when the current value of the controller does not reach the first preset current value, at this time, the heat generated by the controller is less, and even if the ambient temperature is greater than the first set target value, the normal operation of the controller is not affected, and based on this, when the current value of the controller is less than or equal to the first preset current value, the second drain hole is maintained in a completely closed state.
Similarly, the current value of the controller may also reach or exceed the third preset current value, and in other embodiments, the number of the second drain holes may be continuously increased to improve the cooling effect on the controller. However, since in some embodiments of the present application, the mobile air conditioner is provided with a pumping assembly, based thereon, step S40 may further include:
Step S43, when the current value is greater than or equal to a third preset current value, the first water discharging assembly is controlled to close the first water discharging holes of the second preset number, the second water discharging assembly is controlled to open the second water discharging holes of the second preset number, and the water pumping assembly 20 is controlled to open.
In other words, in some embodiments of the present application, when the current value of the controller increases to or above the third preset current value based on the case in step S42, the controller increases the heat dissipation efficiency of the controller by controlling the extraction assembly to extract water in the first water tank 11 to flow through the controller to promote the cooling effect provided to the controller.
In addition, in an actual application environment, the temperature of the environment where the mobile air conditioner is located may directly reach a higher temperature, so that the heat dissipation effect of the controller is affected, and therefore, in some embodiments of the present application, please continue to refer to fig. 2, the cooling control method may further include:
and S50, if the environmental temperature value is greater than or equal to a second set target value, and the current value is greater than or equal to a fourth preset current value and less than a fifth preset current value, controlling the first water discharge assembly to close the second preset number of first water discharge holes, and controlling the second water discharge assembly to open the second preset number of second water discharge holes.
Alternatively, the range of values of the second set target value may be 25℃to 43℃or, in other words, the range of values of the second set target value may be 25℃26℃27℃28℃29℃30℃31℃32℃33℃34℃35℃36℃37℃38℃39℃40℃41℃42℃42℃43℃or the like. In addition, the value range of the fourth preset current value may be 1A to 13A, in other words, the value of the fourth preset current value may be 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A, 11A, 12A, 13A, or the like. The range of the fifth preset current value may be 1A to 15A, in other words, the value of the fifth preset current value may be 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A, 11A, 12A, 13A, 14A, 15A, or the like.
If the environmental temperature value reaches or exceeds the second set target value, the influence of the environmental temperature on the heat dissipation effect of the controller increases, and based on this, when the heat generated by the controller itself is slightly more, the second drain holes of the second preset number need to be opened, so as to ensure that the controller can effectively dissipate heat and cool.
Step S60, if the ambient temperature value is greater than or equal to the second set target value and the current value is greater than or equal to the fifth preset current value, the first water draining assembly is controlled to close the second preset number of first water draining holes, the second water draining assembly is controlled to open the second preset number of second water draining holes, and the water pumping assembly 20 is controlled to open.
In the case where step S60 is based on the case of step S50, the current value of the controller is increased to reach or exceed the fifth preset current value, and at this time, the cooling effect required by the controller is increased, based on which, in order to ensure that the controller can cool down effectively, the controller can control the water pumping assembly 20 to be turned on, thereby ensuring that the controller can operate stably.
In addition, when the ambient temperature value is reduced and/or the current value of the controller is reduced, the heat dissipation effect required by the controller is reduced, and based on this, the water pumping assembly 20 may be preferentially controlled to be turned off, and then the number of the second water draining holes may be gradually reduced and opened according to the reduction of the heat dissipation effect required by the controller.
In an embodiment of the present application, in order to execute the above cooling control method, referring to fig. 4, the present application further provides a cooling control device, where the cooling control device is applied to the above mobile air conditioner, and the cooling control device may execute the above cooling control method to improve the technical problem of poor heat dissipation effect of the controller in the prior art.
The cooling control device comprises a first receiving module 1, a first control module 2, a second receiving module 3 and a second control module 4.
The first receiving module 1 is configured to receive an ambient temperature value, where the ambient temperature value represents a temperature of an environment in which the mobile air conditioner is located.
Optionally, the first receiving module 1 is specifically configured to perform step S10 in the foregoing respective figures, so as to achieve a corresponding technical effect.
The first control module 2 is configured to control the first drainage component to be turned on and control the second drainage component to be turned off when the ambient temperature value is less than or equal to the first set target value.
Optionally, the first control module 2 is specifically configured to perform step S20 in the foregoing respective figures, so as to achieve a corresponding technical effect.
The second receiving module 3 is configured to receive a current value when the ambient temperature value is greater than the first set target value, the current value representing a current of the controller.
Optionally, the second receiving module 3 is specifically configured to perform step S30 in the foregoing respective figures, so as to achieve a corresponding technical effect.

Optionally, the second control module 4 is specifically configured to execute step S40 and the sub-steps thereof in the foregoing respective figures, so as to achieve a corresponding technical effect.
It should be noted that the second control module 4 may also be used to execute the above step S50 and step S60 to achieve the corresponding technical effects.
Alternatively, in other embodiments of the present application, the first receiving module 1 and the second receiving module 3 may be the same receiving module, and similarly, the first control module 2 and the second control module 4 may be the same control module.
In summary, the mobile air conditioner, the cooling control method and the device provided in the embodiments of the present application may drain the condensed water to the controller through the second drainage component to cool the controller, thereby achieving the purpose of reducing the temperature of the controller, and thus, the technical problem of poor heat dissipation effect of the controller in the prior art may be improved. Of course, the controller may be used to control the water discharge amount of the first water discharge assembly and the water discharge amount of the second water discharge assembly, thereby controlling the amount of condensed water guided to the controller by the second water discharge assembly according to actual conditions, so as to provide an effective cooling effect to the controller, and improving the stability of the controller. In other words, since the controller radiates heat slowly in the case where the ambient temperature is high, and the controller can be promoted to radiate heat well in the case where the ambient temperature is low; in addition, when the current of the controller is large, the controller generates a large amount of heat. Based on the above, the cooling control method is applied to the mobile air conditioner, and the water discharge of the first water discharge assembly and the water discharge of the second water discharge assembly can be controlled according to the environment temperature of the mobile air conditioner and the current of the controller, so that proper condensed water is provided for the controller according to actual conditions, the heat dissipation effect of the controller is improved, the controller is ensured to stably operate, and the technical problem of poor heat dissipation effect of the controller in the prior art is solved.
