Specifically, the water outlet is arranged at the bottom of the indoor unit 1, and can guide a condensation chamber generated by an evaporator in the indoor unit 1 to the condenser 21 through the pipeline 4; the steam inlet is arranged on the side surface of the indoor unit 1 and is used for introducing the steam in the pipeline 4 into the indoor unit 1;
more specifically, the pipe 4 is divided into three parts, namely a first pipe, a second pipe and a third pipe, by the indoor unit 1, the outdoor unit 2 and the water vapor conversion module 3, and the water discharge port, the inlet of the first pipe, the outlet of the first pipe, the condenser 21, the inlet of the second pipe, the outlet of the second pipe, the water vapor conversion module 3, the inlet of the third pipe, the outlet of the third pipe and the steam inlet are sequentially connected to form a closed loop.
The basis for realizing the humidification function of the embodiment is condensed water generated by the air conditioner, and the condensed water can be directly used for humidification without frequent addition, so that inconvenience caused by frequent water addition is avoided; the air conditioner has simple structure and convenient use; secondly, the condensed water in the traditional technology is generally directly discharged, so that not only is the environment influenced, but also certain waste is caused, and the embodiment skillfully takes the condensed water as the basis for realizing the humidifying function, so that the energy-saving advantage is achieved; in addition, the humidifying function is integrated on the air conditioner, so that the using number of household appliances is reduced;
in addition, when the air conditioner in this embodiment is used for refrigeration, the water vapor conversion assembly receives condensed water generated by the evaporator of the indoor unit 1, the condensed water is subjected to first evaporation purification by the condenser 21 of the outdoor unit 2 to obtain first-stage steam, the first-stage steam is subjected to second evaporation purification by the water vapor conversion assembly 3 to obtain second-stage steam, and the second-stage steam enters the indoor unit 1 through the steam inlet to further humidify air; as is known, evaporation is accompanied by purification, because water containing impurities can be evaporated into water vapor at 100 ℃ when the water is heated, and other impurities cannot be evaporated, the evaporation process is necessarily accompanied by purification, so that the water vapor in the room is finally blown to be safer and healthier.
When the air conditioner of the present embodiment is in a heating state, the water vapor conversion assembly 3 receives condensed water generated by the condenser 21 of the outdoor unit 2, and water vapor is obtained after passing through the water vapor conversion assembly 3 and enters the indoor unit 1 through the steam inlet, thereby humidifying air. In this process, when the condensed water flows into the water vapor conversion component 3 through the pipe 4, there is also partial evaporation, which corresponds to the first evaporation purification of the air conditioner in the condenser 21, and then the second evaporation purification similar to the refrigeration.
That is, the air conditioner provided by the embodiment has the humidifying function no matter which working state the air conditioner is in.
In a specific embodiment: the water vapor conversion assembly 3 comprises a condensing unit 31 and an evaporating unit 32, and the condensing unit 31 and the evaporating unit 32 are arranged in sequence along the flowing direction of the condensed water; and the evaporation unit 32 serves to convert the condensed water in the liquid state into water vapor.
Specifically, the main functions of the condensing unit 31 are: changing the water vapor into water, namely realizing condensation; the main functions of the evaporation unit 32 are: changing water into vapor, namely realizing evaporation; the evaporation and the condensation are two opposite physical processes, the embodiment changes the water used for humidification into distilled water through condensation and evaporation, and the distilled water is high in purity and basically free of impurities, so that the embodiment enables the water vapor in the evaporation chamber to have water quality and the humidified air to be healthier.
More specifically, when the air conditioner in the present embodiment is used for cooling, the indoor unit 1 generates condensed water, the condensed water first passes through the condenser 21 of the outdoor unit 2, the condenser 21 releases heat, the distilled water is evaporated for the first time by the heat to become steam, the steam enters the condensing unit 31 along the pipe 4, is condensed into water by the condensing unit 31, and then enters the evaporating unit 32 along the pipe, and is evaporated into steam by the evaporating unit 32, and the steam is used for humidifying air;
when the air conditioner in this embodiment is used for heating, the condensed water generated by the condenser 21 enters the pipe 4, and a part of the condensed water is evaporated into water vapor in the pipe 4, and then enters the condensing unit 31, and is totally condensed into water by the condensing unit 31, and then enters the evaporating unit 32 along the pipe, and is evaporated into water vapor by the evaporating unit 32, and the water vapor is used for humidifying air.
In addition, a switch 33 is provided on the pipe 4 between the condensing unit 31 and the evaporating unit 32, and when the amount of water in the condensing unit 31 is insufficient, the switch 33 is turned off.
In a specific embodiment: the condensing unit 31 includes a condensing chamber 311, a semiconductor cooling plate 312 and a first fan 313, the semiconductor cooling plate 312 and the first fan 313 are both disposed in the condensing chamber 311, and a water outlet 314 is disposed on the condensing chamber 311.
Specifically, under the action of the first fan 313, the water vapor in the pipeline 4 enters the condensation chamber 311 and adheres to the semiconductor chilling plate 312, and the condensed water entering the condensation chamber 311 through the pipeline 4 is discharged together with impurities through the water outlet 314; the water vapor attached to the semiconductor chilling plates 312 is pre-chilled to be converted into water droplets and then introduced into the evaporation unit 32 through a pipe.
In order to ensure that water droplets attached to the semiconductor chilling plates 312 can smoothly flow into the evaporation unit 32, the semiconductor chilling plates 312 are inclined downward in the condensation chamber 311 along the flow direction of the condensed water; thus, the condensed water evaporated by the condenser 21 and/or the pipe 4 is changed into steam, and is condensed into water drops by the semiconductor chilling plates 312, and the water drops are collected at one end inclined downwards along the semiconductor chilling plates 312 and then drop into the condensing chamber 311 under the action of gravity.
In the design process, if the right side of the semiconductor chilling plate 312 is inclined downward (in the direction of fig. 1), the water outlet 314 is disposed at the left side in the condensation chamber 311, so as to prevent the condensed water droplets from being discharged along the water outlet 314.
In a specific embodiment: the condensation chamber 311 has an inlet end receiving the liquid or gas in the conduit 4 and an outlet end delivering the liquid out of the condensation chamber 311 and arranged inclined downwards along the flow direction of the condensed water; a first fan 313 is provided at the inlet end.
More specifically, an inlet is opened on one of the side walls of the condensation chamber 311, and the inlet is used for receiving condensed water and/or water vapor from the pipeline 4; an outlet is formed in the other side wall and used for conducting condensed water formed after condensation to the evaporation unit; the bottom surface of the condensing chamber 311 is divided into a first part and a second part, wherein the water outlet 314 is arranged in the first part, one end of the second part close to the water outlet 314 inclines upwards, and the semiconductor chilling plate 312 which is arranged obliquely is arranged above the second part which is arranged obliquely; in this way, when the water drops fall onto the second portion by the gravity of the water drops, the water drops can smoothly flow toward the direction in which the evaporation unit 32 is located.
In a specific embodiment: the evaporation unit 32 includes an evaporation chamber 321 and semiconductor heating fins 322, and the semiconductor heating fins 322 are located in the evaporation chamber 321.
Thus, after the water is introduced into the evaporation chamber 321, the water is converted from a liquid state to a gas state under the action of the semiconductor heating sheet 322, so as to prepare for subsequent humidification; the plurality of semiconductor heating sheets 322 are uniformly arranged in the evaporation chamber 321, so that the evaporation of the water droplets can be efficiently realized by the semiconductor heating sheets 322, and the water droplets are uniformly atomized.
The semiconductor heating sheet 322 is a high-efficiency heat transfer element, the heat conductivity coefficient of the semiconductor heating sheet 322 is 103-104 times that of copper, and the main function is to transfer the heat of the semiconductor refrigerating sheet 312 to the semiconductor heating sheet 322 in a working state, so that the temperature of the semiconductor heating sheet 322 is increased, and the moisture in the evaporation chamber 321 is evaporated and then humidified indoors.
In a specific embodiment: the semiconductor chilling plate 312 is connected with the semiconductor heating plate 322, and the heat of the semiconductor chilling plate 312 can be conducted to the semiconductor heating plate 322.
In principle, the semiconductor cooling plate 312 and the semiconductor heating plate 322 together form a heat transmission tool, when a thermocouple formed by connecting an N-type semiconductor material and a P-type semiconductor material has current flowing through the thermocouple, heat transfer occurs between the two ends, and the heat is transferred from one end to the other end, so that temperature difference is generated to form a cooling end and a heating end.
More specifically, as shown in fig. 2, the semiconductor chilling plate 312 and the semiconductor heating plate 322 are actually components on the same device, and structurally, two ends of the semiconductor chilling plate 312 are connected to the dc power supply 315, the semiconductor chilling plate 312 is also in contact with the red copper block 316, and the semiconductor heating plate 322 is inserted into the red copper block 316; and, around the semiconductor heating sheet 322, there are also provided fins 317, the fins 317 being a heat exchange element for improving the heat exchange efficiency of the semiconductor heating sheet 322.
In a specific embodiment: an evaporator 11 is arranged in the indoor unit 1, a detection unit 12 is arranged above the evaporator 11, a water receiving tray 13 is arranged below the evaporator 11, the water receiving tray 13 is arranged in an inclined mode, and a water outlet is formed in one end, inclined downwards, of the water receiving tray 13.
Specifically, the detection unit 12 is disposed at the air inlet of the indoor unit 1, the water pan 13 is disposed below the evaporator 11, and can receive the condensed water falling from the evaporator 11, and the water pan 13 is disposed obliquely, so that the condensed water can flow to the outdoor unit 2 through the water outlet more smoothly.
