fig. 1 is a flowchart of a control method of a mobile air conditioner according to an embodiment of the present invention.
Detailed Description
A mobile air conditioner according to an embodiment of the present invention, including a compressor, a lower fan, a pumping motor, a water receiving tank, a water pump, a temperature sensor, and a controller, is described with reference to fig. 1.
The mobile air conditioner performs a refrigeration cycle of the mobile air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator in the present application. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The mobile air conditioner can adjust the temperature of the indoor space throughout the cycle.
Specifically, the refrigerant circulation loop circulates the refrigerant in a loop formed by a compressor, a condenser, an expansion valve, an evaporator, a four-way valve and a pressure reducer; the compressor is used for compressing low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure refrigerant gas and discharging the high-temperature and high-pressure refrigerant gas to the condenser; the water receiving tank is used for receiving the condensed water generated by the condenser, and a low water level switch and a high water level switch are arranged in the water receiving tank; the water pumping motor is used for pumping the condensed water in the water receiving tank onto the condenser; the water pump is connected with the water receiving tank; the temperature sensor is used for detecting the exhaust temperature of the compressor; the controller is configured to control the water beating motor to stop when receiving the cleaning instruction. Wherein, the "discharge temperature" may refer to a temperature of the compressor body.
The controller is configured to control the water beating motor to stop when receiving the cleaning instruction. The method comprises the steps of detecting the exhaust temperature of a compressor, controlling the running state of the compressor and/or a water pumping motor to increase the amount of condensed water in a water receiving tank until a high water level switch is closed when the detected exhaust temperature of the compressor does not reach a first preset threshold value, controlling the water pumping motor to run and start a water pump, and turning off the water pump when a low water level switch is turned off.
It should be noted that, the high water level switch and the low water level switch may be both sensors, the low water level switch is used to detect whether the condensed water in the water receiving tank is located at the preset low water level, and the high water level switch is used to detect whether the condensed water in the water receiving tank is located at the preset high water level. When the high water level switch is closed, the condensed water in the water receiving tank is higher than the preset high water level or is flush with the preset high water level; when the high water level switch is switched off, the condensed water in the water receiving tank is lower than the preset low water level or is flush with the preset high water level. The working principle of the low water level switch is the same as that of the high water level switch, and the detailed description is omitted here.
It can be understood that, because of the long-time operation back of mobile air conditioner, the foreign matter can appear in the water receiving tank, and the foreign matter can block up the outlet, and lead to the capacity of water receiving tank to become low, can influence the normal use of water pump, the motor of fetching water even. Therefore, the mobile air conditioner can enter a cleaning mode to discharge foreign matters in the water receiving tank. The water beating motor of the mobile air conditioner is used for beating the condensed water in the water tank to the condenser, so that the condenser can be cleaned, and meanwhile, the water beating motor can stir the water in the water receiving tank, so that the foreign matter sinking effect is prevented from being influenced.
The water pump is connected with the water receiving tank, so that condensed water in the water receiving tank can be conveniently discharged. The controller is configured to control the water beating motor to stop when receiving the cleaning instruction so as to prevent the condensed water in the water receiving tank from being atomized, and therefore more condensed water can be collected in the water receiving tank quickly. The lower fan operates at the lowest wind speed, which may be beneficial to increase the discharge temperature of the compressor to increase the temperature of the condenser.
The temperature sensor is used for detecting the exhaust temperature of the compressor. When the detected temperature does not reach a first preset threshold value at the exhaust temperature of the compressor, the running state of the compressor and/or the water pumping motor is controlled to increase the amount of condensed water in the water receiving tank, so that the condensed water in the water receiving tank quickly reaches a preset high water level. And when the low water level switch is switched off, the water pump is switched off. At this moment, can judge that the water level of the comdenstion water in the water receiving tank is higher, the foreign matter in the water receiving tank can be taken out to the drainage comdenstion water, consequently, can start the water pump, high water level switch is closed, this moment, the water level of the comdenstion water in the water receiving tank is higher, the operation of the motor of beating water is so that stir the comdenstion water in the basin, prevent that the foreign matter from sinking to the end, and start the water pump and carry out the drainage, when low water level switch disconnection, this moment, the comdenstion water level in the water receiving tank has been less than predetermined low water level department, close the water pump, then can withdraw from cleaning function.
According to the mobile air conditioner provided by the embodiment of the invention, when the water level in the water receiving tank reaches the preset high water level, the water pump is started to drain water, so that foreign matters in the water receiving tank can be completely drained, the speed of gathering condensed water by the water receiving tank can be increased by starting the water pumping motor when the water level reaches the high water level, and meanwhile, the foreign matters in the water tank can be stirred by the water pumping motor during drainage, so that the foreign matters are further completely drained. The exhaust temperature of the compressor is adjusted by controlling the frequency of the compressor and the lower fan, so that the exhaust temperature of the compressor can be guaranteed to be reasonable, the condition of trip is prevented, and the generation speed of condensed water can be guaranteed. Simultaneously, judge the water level condition of the comdenstion water of current water receiving tank through high water level switch, low water level switch, judge that the mode is simple and the degree of accuracy is high, and the rejection thing of the water receiving tank of mobile air conditioner is effectual, prevents that the foreign matter from blockking up the outlet or reducing the basin capacity, prevents to beat water motor and water pump and receive the foreign matter too much and influence life, has improved mobile air conditioner's life and job stabilization nature.
In some embodiments, the mobile air conditioner further comprises: a lower fan for flowing outside air through the condenser to adjust a temperature of the condenser. For example, the lower fan may lower the temperature of the condenser. The measuring body of the controller for increasing the condensed water in the water receiving tank is configured to control the current operation frequency of the compressor to be increased and/or the lower fan to be stopped. The amount of the condensed water in the water receiving tank can be increased by controlling the current operation frequency of the compressor to rise and the lower fan to stop operation, for example, the water beating motor can be controlled to stop to prevent the condensed water in the water receiving tank from being atomized and evaporated, so that more condensed water can be collected in the water receiving tank quickly. Or the temperature of the condenser can be increased by operating the lower fan at the lowest wind speed, so that the rate of generating condensed water by the condenser can be increased, and the amount of the condensed water in the water receiving tank can be increased.
Further, the controller is configured to control the current operation frequency of the compressor to increase and the lower fan to stop operating when the detected exhaust temperature does not reach a second preset threshold, the second preset threshold being smaller than the first preset threshold; at this moment, the exhaust temperature of the compressor is low, so that a large amount of condensed water cannot be rapidly generated, and the exhaust temperature of the compressor needs to be increased to ensure the cleaning efficiency, so that the frequency of the compressor can be increased, the lower fan is controlled to stop running, and the generation of a large amount of condensed water is ensured rapidly. The compressor and the lower fan can simultaneously improve the efficiency of generating condensed water.
And when the detected exhaust temperature reaches the second preset threshold value and does not reach the first preset threshold value, controlling the current running frequency of the compressor to be unchanged and stopping running of the lower fan. That is, the exhaust temperature range of the compressor is reasonable, a large amount of quick condensate water can be generated, the refrigerating capacity is good, and the machine tripping caused by overhigh temperature of the compressor can be avoided. Therefore, at this time, the current operating frequency of the compressor is not changed, that is, the discharge temperature of the compressor is moderate, and the frequency of the compressor does not need to be changed. And the lower fan stops running to reduce the evaporation condition of the condensed water, and the water receiving tank is favorable for quickly collecting a large amount of condensed water. For example, the first predetermined threshold may be 80 ℃ to 90 ℃. Further, the first preset threshold may be 85 ℃. The second predetermined threshold may be 40-50 ℃. Further, the second preset threshold may be 45 ℃.
In some embodiments, the controller is further configured to reduce the frequency of the compressor and/or control the lower fan to operate when the detected discharge temperature of the compressor reaches a first preset threshold. That is to say, at this moment, the exhaust temperature of compressor is higher, and in order to protect the compressor, prevent that the compressor from jumping, can reduce the exhaust temperature of compressor through the mode that reduces the frequency of compressor, control lower part fan operation, has guaranteed the job stabilization nature and the life of compressor.
Further, controlling the lower fan operation is specifically configured such that the lower fan operates at the highest wind speed. Therefore, the temperature of the compressor is high, the priority of reducing the temperature of the compressor is higher than the priority of preventing condensed water from evaporating, and therefore the lower fan runs at the highest wind, the exhaust temperature of the compressor can be effectively reduced, and the compressor is prevented from tripping.
In some embodiments, the control of the operation of the water beating motor is specifically configured such that the water beating motor operates at the highest rotation speed, so that the speed of the water beating motor for stirring the condensed water can be ensured, the foreign matter can be effectively prevented from sinking to the bottom, and the effect of discharging the foreign matters is improved.
According to some alternative embodiments of the present invention, the mobile air conditioner further comprises: and the timer is configured to start timing when the low water level switch is turned off and close the water pump when the timing time of the timer reaches a preset time. For example, the timer time is 20s to 40s, and further, the timer time is 30 s. When the accumulated time of the timer reaches the preset time, the water pump is closed, so that the condensed water in the water receiving tank can be completely discharged, and the situation that the condensed water in the water receiving tank cannot be completely discharged is prevented.
The control method of the mobile air conditioner is characterized in that the mobile air conditioner comprises a compressor, a lower fan, a water pumping motor, a water receiving tank, a water pump, a controller and a temperature sensor, wherein a low water level switch and a high water level switch are arranged in the water receiving tank, the water pump is connected with the water receiving tank, and the temperature sensor is used for detecting the exhaust temperature of the compressor.
The control method of the mobile air conditioner comprises the following steps:

s2, when a cleaning instruction is received, the water beating motor is controlled to stop so as to collect more condensed water in the water receiving tank quickly, and the lower fan runs at the lowest wind speed so as to improve the temperature of the condenser and improve the generation speed of the condensed water.
Wherein, the user can send the instruction by operating the remote controller or the display panel of the mobile air conditioner. Also, the mobile air conditioner may include a cleaning indicator lamp to prompt the user that the mobile air conditioner is in a cleaning mode at this time. If the mobile air conditioner does not receive the instruction, the mobile air conditioner continues to operate in a normal mode, the cleaning indicator lamp is not turned on at the moment, and if the mobile air conditioner receives the cleaning instruction, the cleaning indicator lamp is turned on to prompt a user to turn on a cleaning function at the moment.
S3, detecting the exhaust temperature of the compressor; and when the detected exhaust temperature of the compressor does not reach a first preset threshold value, controlling the running state of the compressor and/or the water pumping motor to increase the amount of condensed water in the water receiving tank until the high water level switch is closed. Therefore, the exhaust temperature of the compressor can be divided into a plurality of sections, and different processing modes of each temperature section are controlled, so that the production efficiency of the condensed water, the amount of the condensed water in the water receiving tank and the condition that the compressor is tripped are considered conveniently, and the mobile air conditioner can clean the foreign matters more effectively.
And S4, closing the high water level switch. At the moment, the water level of the condensed water in the water receiving tank is higher than the preset high water level, so that more condensed water in the water receiving tank can be judged, and foreign matters in the water receiving tank can be effectively taken out, so that drainage can be started.
S5, controlling the water pumping motor to operate, starting the water pump, so that the condensed water in the water receiving tank is stirred by the water pumping motor, and meanwhile, the condensed water in the water receiving tank can be pumped to the condenser to clean the condenser.
S61, the low water level switch is disconnected, at the moment, the low water level switch is disconnected, the water level of condensed water in the water receiving tank is judged, the water level is lower than the low water level, foreign matters are discharged out of the water receiving tank along with the discharged condensed water, the foreign matter discharging effect of the water receiving tank of the mobile air conditioner is good, the water outlet is prevented from being blocked by the foreign matters or the capacity of the water tank is reduced, the service life of the water pumping motor and the water pump is prevented from being influenced by the excessive foreign matters, and the service life and the working stability of the mobile air conditioner are improved. Of course, if the low level switch is not turned off, step S5 is repeated.
And S7, turning off the water pump. To complete the cleaning operation. Of course, it can be understood that if the low water level switch is not turned off, the water level is high, and the condensed water is not drained completely, so that the operation of the water pumping motor needs to be controlled continuously, and the water pump needs to be kept on until the low water level switch is turned off.
According to the control method of the mobile air conditioner, when the water level in the water receiving tank is high, the water pump is started to drain water, foreign matters in the water receiving tank can be completely drained, when the water level reaches the high water level, the water pumping motor is started, the water collecting speed of the water receiving tank can be increased, and meanwhile, the water pumping motor can stir the foreign matters in the water tank during drainage, so that the foreign matters can be further completely drained. The quantity of the condensed water in the water receiving tank is adjusted and increased by controlling the frequency of the compressor and the lower fan, so that the quantity of the condensed water in the water receiving tank and the generation speed of the condensed water can be increased. Meanwhile, the water level condition of the condensate water of the current water receiving tank is judged through the high water level switch and the low water level switch, the judging mode is simple, the accuracy is high, and the foreign matter discharging effect of the water receiving tank is good.
Further, the mobile air conditioner further includes: and the lower fan is used for enabling outside air to flow through the condenser so as to adjust the temperature of the condenser, and the increase of the amount of the condensed water in the water receiving tank is specifically to control the current running frequency of the compressor to be increased and/or the lower fan to stop running. For example, the water beating motor can be controlled to stop to prevent the condensed water in the water receiving tank from being atomized and evaporated, so that more condensed water can be collected in the water receiving tank quickly. Or the temperature of the condenser can be increased by operating the lower fan at the lowest wind speed, so that the rate of generating condensed water by the condenser can be increased, and the amount of the condensed water in the water receiving tank can be increased. Moreover, the current operating frequency of the compressor is controlled to rise, and meanwhile, the lower fan stops operating, so that the improvement of the amount of condensate water of the water receiving tank, the speed and the cleaning efficiency are further facilitated.
In some embodiments, the control method comprises the steps of:
s31, when the detected exhaust temperature does not reach a second preset threshold value, controlling the current running frequency of the compressor to rise, stopping running of the lower fan, and enabling the second preset threshold value to be smaller than the first preset threshold value. At the moment, the exhaust temperature of the compressor is moderate, and a large amount of condensed water can be ensured to be quickly generated only by stopping the operation of the lower fan.
In some embodiments, the control method of the mobile air conditioner further includes the steps of:
s32, detecting the exhaust temperature of the compressor; and when the detected temperature of the compressor reaches the first preset threshold value, reducing the frequency of the compressor and/or controlling the operation of a lower fan. For example, the frequency of the compressor is reduced and the lower fan operation is controlled. That is to say, at this moment, the exhaust temperature of compressor is higher, and in order to protect the compressor, prevent that the compressor from jumping, can reduce the exhaust temperature of compressor through the mode that reduces the frequency of compressor, control lower part fan operation, has guaranteed the job stabilization nature and the life of compressor. For example, the lower fan is operated with the highest wind to further lower the discharge temperature of the compressor, improving the cooling efficiency.
Further, the control method of the mobile air conditioner further comprises the following steps:
s33, detecting the exhaust temperature of the compressor; when the detected exhaust temperature does not reach a second preset threshold value, controlling the current running frequency of the compressor to rise, and stopping running of the lower fan, wherein the second preset threshold value is smaller than the first preset threshold value, for example, the frequency of the compressor is increased, and the lower fan is controlled to stop running. At this moment, the exhaust temperature of the compressor is low, so that a large amount of condensed water cannot be rapidly generated, and the exhaust temperature of the compressor needs to be increased to ensure the cleaning efficiency, so that the frequency of the compressor can be increased, the lower fan is controlled to stop running, and the generation of a large amount of condensed water is ensured rapidly. Here, "reaching the first preset threshold" may mean being greater than the first preset threshold. Not reaching the "first preset threshold" may mean being less than or equal to the first preset threshold.
In some embodiments, the mobile air conditioner further comprises a timer; the control method of the mobile air conditioner further comprises the following steps:
and S62, starting timing by a timer when the low water level switch is turned off, and closing the water pump when the timing time of the timer reaches a preset time. Certainly, in order to further ensure that the condensed water in the water receiving tank is completely drained, when the low water level switch is turned off, the timer counts and accumulates the preset time, and then the next step is carried out. For example, the predetermined time of the timer may be 30 s.
