Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The embodiment of the invention provides a control method of a mobile air conditioner, which comprises a water tank and a chassis, wherein the water tank is used for containing evaporator condensate water. The chassis is arranged below the water tank, and a control valve is arranged between the water tank and the chassis. Optionally, the water tank is fixed on a fixing bracket of the evaporator, and the control valve is arranged at the bottom of the water tank. Only a water tank and a control valve are added on the hardware, so that the cost is low.
Wherein, the basin directly accepts the comdenstion water that the evaporimeter produced, then the comdenstion water in the basin gets into the chassis through this control valve. In this embodiment, through controlling the opening and closing of this control valve, can adjust the volume that the comdenstion water got into the chassis to prevent the full protection fault of water, improve user experience.
Fig. 1 is a schematic flowchart of a control method of a mobile air conditioner, which is applied to the mobile air conditioner, in an embodiment of the present invention, and includes the following steps:
s102, periodically acquiring a first water level of the chassis.
In order to accurately acquire the amount of condensed water in the base plate, a first water level sensor may be provided in the base plate, and the first water level sensor may be connected to a controller of the mobile air conditioner, and the controller may periodically acquire a water level signal of the first water level sensor. In this embodiment, the determination steps described in the following embodiments are performed each time the water level signal of the first water level sensor is obtained, so as to control the states of the water pumping motor and the control valve, and output a water full protection signal.
And S104, if the first water level is greater than or equal to the first early warning water level of the water tank, controlling the control valve to be closed, and controlling the water fetching motor to operate.
The first early warning water level is a preset early warning water level threshold, when the water level of the chassis is higher than the first early warning water level, the water quantity in the chassis is larger, and the risk of water fullness is higher when condensed water is continuously injected. Under the condition, the control valve can be closed, and the condensed water is temporarily stored in the water tank and stops being injected into the chassis, so that the chassis is prevented from being full of water. Under the condition, the water pumping motor is controlled to operate, the heat exchange efficiency of the condenser is improved, and the condensed water on the base plate volatilizes along with the condensed water.
Because the control valve is closed, the condensed water is temporarily stored in the water tank, the rotating speed of the water beating motor is not required to be increased to increase the volatilization speed of the condensed water, and the noise value of the water beating motor is smaller.
And S106, if the first water level is smaller than the first early warning water level and larger than the water beating trigger water level of the water tank, controlling the control valve to be opened, and controlling the water beating motor to run.
The water fetching trigger water level is a preset initial water level threshold value of the operation of the water fetching motor, and when the water level of the chassis is higher than the water fetching trigger water level, the water amount in the chassis is indicated to meet the minimum requirement of the operation of the water fetching motor. If the water level is lower than the water pumping trigger water level, the water pumping motor stops when no water or less water exists in the chassis, and therefore electric energy is saved.
Under the condition that the first water level is smaller than the first early warning water level and is larger than the water fetching trigger water level of the water tank, the control valve can be opened, and the condensed water temporarily stored in the water tank begins to be injected into the chassis. The operation of the water-fetching motor can increase the heat exchange efficiency of the condenser, and the condensed water on the chassis volatilizes.
It should be noted that in the process of executing S106, the condensed water is continuously injected into the chassis until the water level of the chassis meets the condition of S104, and then the operation is executed according to the action of S104; and in the process of executing S104, the condensed water stops being injected into the chassis, the water level of the chassis is reduced until the condition of S106 is met, and the operation is executed according to the action of S106. The S104 and the S106 can run circularly, the water level in the chassis is kept safe, and the rotating speed of the water fetching motor does not need to be increased.
The control method of the mobile air conditioner provided by the embodiment comprises the water tank and the base plate, the water tank is used for containing the evaporator condensate water, the control valve is arranged between the water tank and the base plate, the condenser is controlled to be opened and closed according to the water level of the base plate, whether the condensate water flows into the base plate or not is controlled, the water quantity in the base plate can be effectively controlled, the water full protection fault is avoided, the rotating speed of the water pumping motor is not required to be improved, the noise is low, only the water tank and the control valve are required to be added, the cost is low, and the control is simple.
The control valve and the water beating motor are controlled based on the first water level of the chassis, and under the condition that the first water level meets other conditions, the method can further comprise the following steps:
if the first water level is lower than the water fetching trigger water level, controlling the control valve to be opened, and controlling the water fetching motor to be stopped; and if the first water level is greater than or equal to the first full water level of the chassis, controlling the control valve to close, and controlling the air conditioner to stop and output a full water protection signal.
When the first water level is lower than the water beating triggering water level, no water or less water is in the chassis, the water beating motor is stopped to save energy, and the control valve is opened to enable condensed water to enter the chassis from the water tank in time. When the first water level is larger than or equal to the first water full level of the chassis, the danger of chassis water overflow is indicated to be about to occur, the air conditioner is controlled to stop, and a water full protection signal is output, so that water leakage of the mobile air conditioner can be avoided.
In consideration of the situation that the condensed water is temporarily stored in the water tank and stops being injected into the chassis, if the air is in a high humidity state and the condensed water in the water tank continuously increases, the overflow condition may occur, and the safe operation of the mobile air conditioner is not facilitated. Based on this, in the embodiment, a second water level sensor is arranged in the water tank to obtain the amount of the condensed water in the chassis, and corresponding control steps are provided to coordinate the amounts of the condensed water in the water tank and the chassis. The above method may further comprise the steps of:
(1) and periodically obtaining a second water level of the water tank. The controller may periodically acquire a water level signal of the second water level sensor in a similar manner to the first water level acquisition of the chassis. The determination steps described in the subsequent embodiments are performed each time the water level signal of the second water level sensor is acquired.
(2) And if the second water level is greater than or equal to the second early warning water level of the water tank and the first water level is less than the first early warning water level, controlling the control valve to open.
(3) And if the second water level is greater than or equal to the second full water level of the water tank and the first water level is less than the first full water level of the chassis, controlling the control valve to open.
Wherein the first full water level is greater than the first pre-warning water level, and the second full water level is greater than the second pre-warning water level.
The above-described judgment processes (2) and (3) are performed on the basis of the method shown in fig. 1, i.e., the judgment processes (2) and (3) are compatible with the judgment conditions of the first water level shown in fig. 1. Specifically, the second early warning water level is a preset early warning water level threshold, when the water level of the water tank is higher than the second early warning water level, it is indicated that the water amount in the water tank is large, and then the condensate water is continuously received, so that a large water full risk exists. In this case, if the first water level is lower than the first early warning water level (corresponding to the control valve is opened in fig. 1), the control valve can be opened to prevent the water level in the water tank from rising continuously, and a part of space in the chassis is still available for accommodating condensed water, so that the water amount in the water tank and the water amount in the chassis are coordinated.
When the second water level is greater than or equal to the second water full level of the water tank, it indicates that overflow of water from the water tank is about to occur, and if there is some space in the chassis, i.e. the first water level is less than the first water full level, the condensed water can be partially released to the chassis, thereby coordinating the water volume in the water tank and the chassis.
On the basis of the control steps, a supplementary step of controlling the control valve and the water beating motor based on the volume of the condensed water in the water tank and the chassis is also provided, so that the efficiency of coordinating the water quantity in the water tank and the chassis is further improved. It may be performed after the steps shown in fig. 1 are performed, or before it.
Based on this, the above method further comprises:
under the condition that the control valve is closed and the water fetching motor is stopped, if the volume of the condensed water corresponding to the second water level is less than or equal to the residual volume of the condensed water corresponding to the first water level, controlling the control valve to be opened and the water fetching motor to operate; alternatively, the first and second electrodes may be,
and under the condition that the control valve is opened and the water beating motor operates, if the residual volume of the condensed water corresponding to the second water level is larger than that of the condensed water corresponding to the first water level, the control valve is controlled to be closed and the water beating motor operates.
Aiming at the scene that the control valve is closed, if the volume of the condensed water corresponding to the second water level is smaller than or equal to the residual volume of the condensed water corresponding to the first water level, the condensed water in the water tank is completely released into the chassis, and the water cannot overflow, so that the condensed water can be released into the chassis for the water pumping motor to pump water, and the heat exchange efficiency of the condenser is improved. Aiming at the scene that the control valve is opened, if the residual volume of the condensed water corresponding to the second water level is larger than that of the condensed water corresponding to the first water level, the problem that the chassis water overflows easily occurs when the condensed water is continuously released, and the water fetching motor is continuously operated under the condition, so that the control valve is closed.
Fig. 2 is a schematic flowchart of another control method of a mobile air conditioner in an embodiment of the present invention, including the steps of:
and S201, refrigerating and starting the mobile air conditioner. After the machine is started, the evaporator generates condensed water, and the condensed water enters a water tank of the evaporator. Under the condition that the control valve is opened, condensed water in the water tank enters the chassis through the control valve.
S202, the water level sensor detects the water level of the chassis. The water level sensor may also be a water level switch.
And S203, judging whether the water level of the chassis is greater than the 1 st set water level. If yes, go to step S204, otherwise go to step S208. When the water level switch on the chassis detects that the water level reaches or does not reach the 1 st set value, the control valve is opened, the water pumping motor is stopped, no water or less water exists at the moment, and energy conservation is preferentially considered.
And S204, judging whether the water level of the chassis is greater than the 2 nd set water level. If so, S205 and S209 are executed, otherwise, S208 is executed. When the water level switch on the chassis detects that the water level reaches the 2 nd set value, the control valve is opened, the water pumping motor is started, and the heat exchange efficiency of the condenser is increased.
And S205, judging whether the water level of the chassis is greater than the 3 rd set water level. If yes, S207, S209, and S211 are executed, and if no, S206 is executed. When the water level switch on the chassis detects that the water level reaches the 3 rd set value, the control valve is closed, the condensed water is temporarily stored in the water tank of the evaporator fixed bracket, the water-fetching motor is started, at the moment, the number of the retained condensers in the chassis is large, the condenser is continuously increased, and the controllability (such as circuit short circuit) of the air conditioner is influenced.
And S206, judging whether the water level of the chassis is less than the 4 th set water level. If so, go to S210, otherwise go to S205. On the premise of S205, after the water beating motor operates for a period of time, the evaporation of water in the chassis is reduced, and when the water level switch detects that the water level is reduced to a 4 th fixed value, the control valve is opened, and the water beating motor works; after the power-on, S205 and S206 are circulated.
And S207, judging whether the water level of the chassis is greater than the 5 th set water level. If so, S212 is executed, otherwise, S205 is executed. When the water level switch on the chassis detects that the water level reaches the 5 th set value, all loads of the air conditioner are shut down, water full protection is reported, at the moment, the water level exceeds the limit value, and the reliability cannot be met.
And S208, stopping the water fetching motor.
And S209, operating the water fetching motor.
And S210, opening the control valve.
And S211, controlling the valve to be closed.
And S212, stopping the machine, and reporting water full protection.
The method provided by the embodiment has the advantages that the rotating speed of the water pumping motor is not required to be increased under the high humidity condition, the noise value is small, only the water tank, the control valve and the water level switch are added to hardware, and the cost is low.
