In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to an embodiment of the present invention, a method for controlling a dehumidifier is provided, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method of the present invention. The control method of the dehumidifier can be applied to the dehumidifier with the water pump circulating system, and the control method of the dehumidifier can comprise the following steps: step S110 to step S130.
In step S110, the outlet air temperature of the dehumidifier is obtained when the compressor of the dehumidifier is in operation.
Optionally, the obtaining of the outlet air temperature of the dehumidifier in step S110 may include: and acquiring the temperature at the air outlet of the dehumidifier detected and fed back by the temperature sensing module, and taking the temperature at the air outlet of the dehumidifier as the air outlet temperature of the dehumidifier.
The temperature sensing module is arranged at an air outlet of the dehumidifier and can be used for detecting and feeding back the temperature at the air outlet of the dehumidifier to a main board of the dehumidifier.
For example: and a temperature sensing bulb is added at the air outlet of the dehumidifier, and the temperature is fed back to the main board.
Therefore, the temperature sensing module is arranged at the air outlet of the dehumidifier to detect the air outlet temperature of the dehumidifier, so that the air outlet temperature of the dehumidifier can be conveniently and accurately acquired.
At step S120, it is determined whether the outlet air temperature of the dehumidifier is greater than or equal to a set temperature threshold.
In step S130, if the outlet air temperature of the dehumidifier is greater than or equal to the set temperature threshold, the condenser of the dehumidifier is cooled and/or depressurized to reduce the outlet air temperature of the dehumidifier.
For example: low-temperature water is sprayed to the surfaces of the fins of the condenser, and preferably condensed water in a water receiving tank of the dehumidifier can be sprayed to the surfaces of the fins of the condenser, so that the surface temperature of the condenser is reduced, the temperature of air blown out from an air duct is reduced, the problem of high air outlet temperature can be solved, and the comfort is improved; the high pressure of the system can be reduced, the compression ratio is reduced, and the energy efficiency is improved; the high pressure of the system can be linearly controlled, the temperature of the pipe is reduced, and the shutdown caused by overhigh temperature of the pipe is reduced; the temperature range of the dehumidifier can be widened, and the indoor excessive sultriness in 3 and 4 months in the south can be avoided.
Therefore, the air outlet temperature of the dehumidifier can be reduced by carrying out temperature reduction and/or pressure reduction treatment on the condenser of the dehumidifier under the condition that the air outlet temperature of the dehumidifier is higher than the set temperature threshold, so that indoor sultry caused by hot working conditions can be avoided, and the comfort feeling of a user is improved.
Optionally, the cooling and/or depressurizing the condenser of the dehumidifier in step S130 may include: by controlling the spraying system, water in a set temperature range is sprayed on the surface of the condenser of the dehumidifier so as to reduce the temperature and/or pressure of the surface of the condenser.
The spraying system can be a preset automatic spraying system or a temporarily built manual spraying system. For example: the automatic spraying system can be automatically started when the outlet air temperature of the dehumidifier is greater than or equal to a set temperature threshold value, so that water or other environment-friendly and safe liquid which can be cooled is sprayed on the surface of the condenser through the automatic spraying system, and the temperature and/or the pressure on the surface of the condenser are/is reduced. Through the manual spraying system, a prompt message can be sent when the outlet air temperature of the dehumidifier is greater than or equal to a set temperature threshold value, so that a user can be prompted to manually build and start the manual spraying system according to the prompt message, water or other environment-friendly and safe liquid which can be cooled is sprayed onto the surface of the condenser through the manual spraying system, and the temperature and/or the pressure of the surface of the condenser are/is reduced.
For example: the air outlet temperature of the dehumidifier can be reduced by cooling the condenser fins, and the comfort is improved. If the working condition is higher, the compression ratio of the system can be reduced through the water pump circulating system, and the system problems such as shutdown and the like caused by overhigh temperature of the pipe are reduced.
Therefore, the temperature and/or the pressure on the surface of the condenser are/is reduced by controlling the spraying system to spray water on the surface of the condenser, the temperature and/or the pressure on the surface of the condenser can be rapidly reduced, the outlet air temperature of the dehumidifier is reduced, and indoor sultry caused by overhigh outlet air temperature when the indoor temperature is higher is avoided, so that the comfort experience of a user is improved.
More optionally, the spraying system may comprise: and a water pump circulating system. The water pump circulation system may include: the condensed water circulating system takes the condensed water in the water receiving tank of the dehumidifier as the water source.
For example: the water pump circulating system can be applied to the dehumidifier, the outlet air temperature of the dehumidifier is reduced by cooling the condenser fins, and the comfort is improved. Under the higher condition of operating mode, reduce system's compression ratio through water pump circulation system, reduce system's problems such as shut down because of the pipe high temperature leads to.
In particular, where the spray system may include a water pump circulation system, controlling the spray system may include: and controlling the water pump circulating system to linearly spray water in the water pump circulating system to the surface of a condenser of the dehumidifier. That is, the water pump circulation system is controlled to be turned on, and the flow rate of the water pump circulation system is linearly controlled to spray water in the water pump circulation system toward the surface of the condenser of the dehumidifier. The water in the water pump circulating system can be water within a set temperature range.
For example: the water pump circulation system can be utilized to control the opening of the water pump and linearly control the flow according to the temperature feedback of the temperature sensing bulb at the air outlet, the condenser is sprayed, the surface temperature and the pressure of the condenser are reduced, and therefore the air outlet temperature of the dehumidifier is reduced.
Therefore, the water in the water pump circulating system is linearly sprayed to the surface of the condenser of the dehumidifier by utilizing the water pump circulating system such as a condensed water circulating system taking condensed water in a water receiving tank of the dehumidifier as a water source, so that the outlet air temperature of the dehumidifier can be stably and gradually reduced, the comfort feeling of a user is stably and gradually improved in a rhythmic manner, and the user is prevented from being uncomfortable due to the sudden high or low temperature.
Still further optionally, the water in the water pump circulation system may comprise: condensed water in a water receiving tank of the dehumidifier. The water pump circulation system is controlled, as can be seen in the following exemplary description of one specific process.
Referring to fig. 2, a flow chart of an embodiment of the method for controlling a water pump circulation system according to the present invention will be further described, wherein the specific process for controlling the water pump circulation system may include: step S210 and step S220.
And step S210, draining the condensed water in the water receiving tank to the top of the condenser by controlling a water pump at the water receiving tank of the dehumidifier. And the spray head at the top of the condenser is controlled to enable the condensed water sprayed by the spray head to flow across the surface of the condenser from top to bottom. And the number of the first and second groups,
and S220, collecting the condensed water left on the surface of the condenser through the condenser of the dehumidifier and the water receiving tray at the bottom of the evaporator, and draining the condensed water left on the surface of the condenser into the water receiving tank again to realize the recycling of the condensed water.
Specifically, the condensed water circulation system may include: water pump, leading water pipe, shower nozzle and receiving disc. For example: can increase water pump and leading water pipe in water receiving tank department, increase the shower nozzle at the condenser top, utilize the comdenstion water in the water pump leads the condenser top in with the water tank, flow through the condenser with water top-down through the action of gravity to realize the cooling, the condenser bottom is furnished with the water collector with the evaporimeter is the same, will be used for the comdenstion water that the cooling flows down to lead to in the water receiving tank once more. Wherein, the water pan assembly is shared to condenser and evaporimeter bottom, can be used for collecting the water that the heat exchanger flows down and lead to the water receiving case.
From this, the comdenstion water through cyclic utilization condenser reduces the air-out temperature, has practiced thrift the required low-temperature water of cooling on the one hand, and on the other hand avoids the comdenstion water to spill over and influence sanitation.
In an alternative example, the controlling the water pump circulation system may further include: before water in a water pump circulating system is linearly sprayed to the surface of a condenser of the dehumidifier, under the condition that a compressor of the dehumidifier is operated, whether the water level height of condensed water in a water receiving tank of the dehumidifier is greater than or equal to a set height threshold value or not is determined, and the water pump circulating system is controlled to be started and is linearly sprayed to the surface of the condenser of the dehumidifier under the condition that the water level height is greater than or equal to the set height threshold value.
For example: and a water pump is added at the water receiving tank and controlled by the main board. The top of the condenser is added with a spray head. The outlet of the water pump is connected with the spray head through a water pipe. The inlet of the water pump is connected with a water pipe, and the lowest end of the water pipe is fixed at a safe water level line (the water pipe can be used for pumping water).
When the dehumidifier is actually used, if the compressor of the dehumidifier is not operated, or if the water level height of the condensed water is smaller than a set height threshold value such as a safe water level under the condition that the compressor of the dehumidifier is operated, the water pump circulating system is closed. Of course, when the compressor of the dehumidifier is running and the water level height of the condensed water is greater than or equal to the set height threshold value, such as the safe water level, if the outlet air temperature of the dehumidifier is less than the set temperature threshold value, such as 37 ℃, the water pump circulation system is also closed.
For example: after the compressor is started, when the water in the water receiving tank exceeds the safe water level, the water pump can start to work at the moment. And when the temperature sensing bulb at the air outlet detects that T is more than or equal to 37 ℃, the water pump is started. Water in the water receiving tank is pumped to the spray head through the water pump and then sprinkled on the top of the condenser through the spray head, and the condenser is cooled by the water from top to bottom, so that the aim of cooling is fulfilled.
Therefore, the water pump circulating system is started when the water level of the condensed water reaches the safe water level, and the water pump circulating system can be reliably and safely used.
A large number of experiments verify that by adopting the technical scheme of the embodiment, the air outlet temperature of the dehumidifier is reduced by cooling the condenser fins, so that indoor sultry can be avoided, and the comfort experience of a user is improved.

For example: and a temperature sensing bulb is added at the air outlet of the dehumidifier, and the temperature is fed back to the main board.
Therefore, the temperature sensing module is arranged at the air outlet of the dehumidifier to detect the air outlet temperature of the dehumidifier, so that the air outlet temperature of the dehumidifier can be conveniently and accurately acquired.

Therefore, the water in the water pump circulating system is linearly sprayed to the surface of the condenser of the dehumidifier by utilizing the water pump circulating system such as a condensed water circulating system taking condensed water in a water receiving tank of the dehumidifier as a water source, so that the outlet air temperature of the dehumidifier can be stably and gradually reduced, the comfort feeling of a user is stably and gradually improved in a rhythmic manner, and the user is prevented from being uncomfortable due to the sudden high or low temperature.
Still further optionally, the water in the water pump circulation system may comprise: condensed water in a water receiving tank of the dehumidifier. The control unit 106 controls the water pump circulation system, as can be seen in the following exemplary description of one specific process.
The control unit 106 may be further configured to control a water pump at the water receiving tank of the dehumidifier to drain the condensed water in the water receiving tank to the top of the condenser. And the spray head at the top of the condenser is controlled to enable the condensed water sprayed by the spray head to flow across the surface of the condenser from top to bottom. The specific functions and processes of the control unit 106 are also referred to in step S210.
The control unit 106 may be further configured to collect condensed water remaining from the surface of the condenser through a water receiving tray at the bottom of the condenser and the evaporator of the dehumidifier, and to guide the condensed water remaining from the surface of the condenser to the water receiving tank again, so as to recycle the condensed water. The specific function and processing of the control unit 106 are also referred to in step S220.
Specifically, the condensed water circulation system may include: water pump, leading water pipe, shower nozzle and receiving disc. For example: can increase water pump and leading water pipe in water receiving tank department, increase the shower nozzle at the condenser top, utilize the comdenstion water in the water pump leads the condenser top in with the water tank, flow through the condenser with water top-down through the action of gravity to realize the cooling, the condenser bottom is furnished with the water collector with the evaporimeter is the same, will be used for the comdenstion water that the cooling flows down to lead to in the water receiving tank once more. Wherein, the water pan assembly is shared to condenser and evaporimeter bottom, can be used for collecting the water that the heat exchanger flows down and lead to the water receiving case.
From this, the comdenstion water through cyclic utilization condenser reduces the air-out temperature, has practiced thrift the required low-temperature water of cooling on the one hand, and on the other hand avoids the comdenstion water to spill over and influence sanitation.
In an optional example, the control unit 106 controls the water pump circulation system, and may further include: the control unit 106 may be further configured to determine whether a water level height of condensed water in a water receiving tank of the dehumidifier is greater than or equal to a set height threshold value under a condition that a compressor of the dehumidifier is operated before water in the water pump circulation system is linearly sprayed onto a surface of a condenser of the dehumidifier, so that the water pump circulation system is controlled to be turned on and the water pump circulation system is linearly sprayed onto the surface of the condenser of the dehumidifier when the water level height is greater than or equal to the set height threshold value.
For example: and a water pump is added at the water receiving tank and controlled by the main board. The top of the condenser is added with a spray head. The outlet of the water pump is connected with the spray head through a water pipe. The inlet of the water pump is connected with a water pipe, and the lowest end of the water pipe is fixed at a safe water level line (the water pipe can be used for pumping water).
When the dehumidifier is actually used, if the compressor of the dehumidifier is not operated, or if the water level height of the condensed water is smaller than a set height threshold value such as a safe water level under the condition that the compressor of the dehumidifier is operated, the water pump circulating system is closed. Of course, when the compressor of the dehumidifier is running and the water level height of the condensed water is greater than or equal to the set height threshold value, such as the safe water level, if the outlet air temperature of the dehumidifier is less than the set temperature threshold value, such as 37 ℃, the water pump circulation system is also closed.
For example: after the compressor is started, when the water in the water receiving tank exceeds the safe water level, the water pump can start to work at the moment. And when the temperature sensing bulb at the air outlet detects that T is more than or equal to 37 ℃, the water pump is started. Water in the water receiving tank is pumped to the spray head through the water pump and then sprinkled on the top of the condenser through the spray head, and the condenser is cooled by the water from top to bottom, so that the aim of cooling is fulfilled.
Therefore, the water pump circulating system is started when the water level of the condensed water reaches the safe water level, and the water pump circulating system can be reliably and safely used.
