[0003] Therefore, the relevant technology generally integrates the humidification function on the air conditioner. The most widely used air conditioner is the wall-mounted air conditioner, which is also called a split air conditioner. In order to make the hot air and cold air blown out from the air conditioner better spread to various parts of the room, the indoor part of the wall-mounted air conditioner is generally installed at a higher position.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example 1

[0037] This embodiment provides an air conditioner, such as Figure 1 As shown, the air conditioner includes an indoor unit 1 and an outdoor unit 2, and the air conditioner also includes a water vapor conversion component 3; the indoor unit 1 has a drain outlet and a steam inlet, and the outdoor unit 2 includes a condenser 21; the drain outlet, the condenser 21, the water vapor conversion component 3 and the steam inlet are connected in sequence through a pipe 4, and the pipe 4 is used to collect condensed water generated by the indoor unit 1 or the outdoor unit 2, and make the condensed water flow along the indoor unit, the outdoor unit and the water vapor conversion component in sequence.

[0038] Specifically, the drain port is provided at the bottom of the indoor unit 1, and the condensation chamber generated by the evaporator in the indoor unit 1 can be drained to the condenser 21 through the pipe 4; the steam inlet is provided at the side of the indoor unit 1, and is used to introduce the steam in the pipe 4 into the indoor unit 1;

[0039] More specifically, the pipe 4 is divided into three parts by the indoor unit 1, the outdoor unit 2 and the water vapor conversion component 3, namely the first pipe, the second pipe and the third pipe. The drain outlet, 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 component 3, the inlet of the third pipe, the outlet of the third pipe and the steam inlet are connected in sequence to form a closed loop.

[0040] The basis for realizing the humidification function in this embodiment is the condensed water generated by the air conditioner, and the condensed water can be directly used for humidification without frequent addition, thus avoiding the inconvenience caused by frequent water addition; and the air conditioner has a simple structure and is easy to use; secondly, in the traditional technology, the condensed water is generally discharged directly, which not only affects the environment but also causes certain waste. This embodiment cleverly uses the condensed water as the basis for realizing the humidification function, which has the advantage of saving energy; and this embodiment integrates the humidification function on the air conditioner, thus reducing the number of household appliances used;

[0041] In addition, when the air conditioner in this embodiment is used for cooling, the water vapor conversion component receives the condensed water produced by the evaporator of the indoor unit 1, and performs the first evaporation purification through the condenser 21 of the outdoor unit 2 to obtain primary steam. Thereafter, the primary steam performs the second evaporation purification through the water vapor conversion component 3 to obtain secondary steam. The secondary steam enters the indoor unit 1 through the steam inlet, thereby humidifying the air. As is well known, evaporation is accompanied by purification, because when water containing impurities is heated, the water can evaporate into water vapor at 100 degrees, and other impurities will not evaporate with it. Therefore, the evaporation process must be accompanied by purification, which makes the water vapor in the room safer and healthier.

[0042] When the air conditioner of this embodiment is in the heating state, the water vapor conversion component 3 receives the condensed water generated by the condenser 21 of the outdoor unit 2, and obtains water vapor after passing through the water vapor conversion component 3. The water vapor enters the indoor unit 1 through the steam inlet, thereby realizing the humidification of the air. In this process, when the condensed water flows into the water vapor conversion component 3 through the pipe 4, part of it will also evaporate. This evaporation is equivalent to the first evaporation purification performed in the condenser 21 during the air conditioner cooling. After that, similar to cooling, the second evaporation purification is performed.

[0043] That is to say, the air conditioner provided in this embodiment has the humidification function no matter what working state the air conditioner is in.

[0044] In a specific embodiment: the water vapor conversion component 3 includes a condensation unit 31 and an evaporation unit 32, and the condensation unit 31 and the evaporation unit 32 are arranged in sequence along the flow direction of the condensed water; and the evaporation unit 32 is used to convert the liquid condensed water into water vapor.

[0045] Specifically, the main function of the condensation unit 31 is to change water vapor into water, that is, to achieve condensation; the main function of the evaporation unit 32 is to change water into water vapor, that is, to achieve evaporation; evaporation and condensation are two opposite physical processes. In this embodiment, the water used for humidification is converted into distilled water through condensation and evaporation. As is known to all, the purity of distilled water is very high and basically contains no impurities. In this way, the water vapor used for evaporation in the room has water quality, and the humidified air is healthier.

[0046] More specifically, when the air conditioner in this embodiment is used for cooling, the indoor unit 1 generates condensed water, which first passes through the condenser 21 of the outdoor unit 2. At this time, the condenser 21 releases heat, and the distilled water evaporates for the first time under the action of the heat and becomes steam. The steam enters the condensing unit 31 along the pipe 4, and condenses into water under the action of the condensing unit 31. Then, it enters the evaporating unit 32 along the pipe, and evaporates into water vapor under the action of the evaporating unit 32. The water vapor is used to humidify the air.

[0047] When the air conditioner in this embodiment is used for heating, the condensed water generated by the condenser 21 enters the pipe 4, and part of the condensed water evaporates into water vapor in the pipe 4, and then enters the condensing unit 31, where it is all condensed into water, and then enters the evaporating unit 32 along the pipe, where it evaporates into water vapor, and the water vapor is used to humidify the air.

[0048] In addition, a switch 33 is provided on the pipe 4 between the condensing unit 31 and the evaporating unit 32. When the amount of water in the condensing unit 31 is insufficient, the switch 33 is closed.

[0049] In a specific embodiment: the condensation unit 31 includes a condensation chamber 311, a semiconductor refrigeration plate 312 and a first fan 313, the semiconductor refrigeration plate 312 and the first fan 313 are both arranged in the condensation chamber 311, and a water outlet 314 is opened on the condensation chamber 311.

[0050] 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 refrigeration plate 312, and the condensed water entering the condensation chamber 311 through the pipeline 4 is discharged from the water outlet 314 together with the impurities; the water vapor attached to the semiconductor refrigeration plate 312 is pre-cooled and converted into water droplets, and then enters the evaporation unit 32 through the pipeline.

[0051] In order to ensure that the water droplets attached to the semiconductor refrigeration plate 312 can flow smoothly into the evaporation unit 32, the semiconductor refrigeration plate 312 is arranged to be tilted downward in the condensation chamber 311 along the flow direction of the condensed water; in this way, after the condensed water evaporated by the condenser 21 and / or the pipeline 4 becomes steam, it is condensed into water droplets through the semiconductor refrigeration plate 312. The water droplets gather at the downward tilted end along the semiconductor refrigeration plate 312, and then drip into the condensation chamber 311 under the action of gravity.

[0052] In the design process, it is assumed that the right side of the semiconductor cooling plate 312 is tilted downward ( Figure 1 In the direction of the middle, the water outlet 314 is arranged on the left side of the condensation chamber 311 to prevent the water droplets formed after condensation from being discharged along the water outlet 314.

[0053] In a specific embodiment: the condensation chamber 311 has an inlet end and an outlet end, the inlet end receives the liquid or gas in the pipeline 4, the outlet end transmits the liquid in the condensation chamber 311, and the outlet end is arranged to be inclined downward along the flow direction of the condensed water; the first fan 313 is arranged at the inlet end.

[0054] More specifically, an inlet is provided on one of the side walls of the condensation chamber 311, and the inlet is used to receive condensed water and / or water vapor from the pipe 4; an outlet is provided on the other side wall, and the outlet is used to conduct the condensed water formed after condensation to the evaporation unit; the bottom surface of the condensation chamber 311 is divided into a first part and a second part, wherein the water outlet 314 is provided in the first part, and the end of the second part close to the water outlet 314 is inclined upward, and the upper part of the inclined second part is the inclined semiconductor refrigeration plate 312; in this way, when the water droplets fall onto the second part under the action of gravity, the inclined setting allows the water droplets to flow smoothly in the direction of the evaporation unit 32.

[0055] In a specific embodiment, the evaporation unit 32 includes an evaporation chamber 321 and a semiconductor heating plate 322 . The semiconductor heating plate 322 is located in the evaporation chamber 321 .

[0056] In this way, after the water is drained into the evaporation chamber 321, under the action of the semiconductor heating plate 322, the water is converted from liquid to gas, preparing for subsequent humidification; a plurality of semiconductor heating plates 322 are arranged, which are evenly arranged in the evaporation chamber 321, so that under the action of the semiconductor heating plates 322, the evaporation of water droplets can be efficiently achieved, and the water droplets are evenly atomized.

[0057] The semiconductor heating plate 322 is a highly efficient heat transfer element. The thermal conductivity of the semiconductor heating plate 322 is 103-104 times that of copper. Its main function is to transfer the heat of the semiconductor cooling plate 312 in the working state to the semiconductor heating plate 322, so that the temperature of the semiconductor heating plate 322 rises, and the water in the evaporation chamber 321 evaporates to humidify the room.

[0058] In a specific embodiment, the semiconductor cooling sheet 312 is connected to the semiconductor heating sheet 322 , and the heat of the semiconductor cooling sheet 312 can be transferred to the semiconductor heating sheet 322 .

[0059] In principle, the semiconductor cooling sheet 312 and the semiconductor heating sheet 322 together constitute a heat transmission tool. When current passes through a thermocouple formed by a piece of N-type semiconductor material and a piece of P-type semiconductor material, heat transfer will occur between the two ends. Heat will be transferred from one end to the other, thereby generating a temperature difference to form a cold and hot end.

[0060] More specifically, if Figure 2 As shown, the semiconductor refrigeration sheet 312 and the semiconductor heating sheet 322 are actually components of the same device. Structurally, both ends of the semiconductor refrigeration sheet 312 are connected to a DC power supply 315, the semiconductor refrigeration sheet 312 is also in contact with a copper block 316, and the semiconductor heating sheet 322 is inserted into the copper block 316; and, surrounding the semiconductor heating sheet 322, fins 317 are also provided, and the fins 317 are a heat exchange element for improving the heat exchange efficiency of the semiconductor heating sheet 322.

[0061] In a specific embodiment, an evaporator 11 is disposed in the indoor unit 1, a detection unit 12 is disposed above the evaporator 11, a water receiving pan 13 is disposed below the evaporator 11, the water receiving pan 13 is inclined, and a drain outlet is provided at one end of the water receiving pan 13 that is inclined downward.

[0062] Specifically, the detection unit 12 is arranged at the air inlet of the indoor unit 1, and the water receiving tray 13 is arranged below the evaporator 11 to receive the condensed water dropped from the evaporator 11, and the water receiving tray 13 is inclined so that the condensed water can flow to the outdoor unit 2 more smoothly through the drain outlet.

[0063] In a specific embodiment: the detection unit 12 includes a humidity sensor and a controller. The humidity sensor detects an indoor humidity signal and sends the indoor humidity signal to the controller. The controller controls the working state of the water vapor conversion component 3 according to the indoor humidity signal.

[0064] A humidity threshold is preset in the controller. When the indoor humidity detected by the humidity sensor is lower than the humidity threshold, it is determined that the indoor humidity is insufficient. At this time, the water vapor conversion component 3 is started, which can be started manually or automatically by the controller. On the contrary, when the indoor humidity detected by the humidity sensor is not lower than the humidity threshold, it is determined that the indoor humidity is sufficient. At this time, the water vapor conversion component 3 is not started.

[0065] In a specific embodiment: a DC power source 315 is applied to both ends of the semiconductor cooling plate 312 , and the controller is used to control the power applied to the semiconductor cooling plate 312 by the DC power source 315 .

[0066] The above-mentioned method of starting the water vapor conversion component 3 through the controller is: starting the DC power supply 315 through the controller; and the controller is also preset with the power of the DC power supply 315 corresponding to each indoor humidity. For example, when the indoor humidity detected by the humidity sensor is less than the humidity threshold, and the absolute value of the difference between the indoor humidity and the humidity threshold is greater than a fixed value, the controller controls the DC power supply 315 to apply a first power to the semiconductor refrigeration plate 312; and when the absolute value of the difference between the indoor humidity and the humidity threshold is not greater than a fixed value, the controller controls the DC power supply 315 to apply a second power to the semiconductor refrigeration plate 312, wherein the first power is greater than the second power.

[0067] In the air conditioner provided in this embodiment, the water vapor conversion component 3 has a high conversion efficiency and a small size. The components included are relatively simple, and the condensation chamber and the evaporation chamber can be designed into a smaller space. The overall water vapor conversion component 3 can be miniaturized and can be installed inside the outdoor unit 2 without occupying valuable indoor space. At the same time, there is no need to increase the size of the outdoor unit 2, and the manufacturing cost of the outdoor unit 2 will not be increased.

[0068] Example 2

[0069] This embodiment provides a humidification control method for an air conditioner, and the humidification control method for an air conditioner is used to control the air conditioner of Embodiment 1, comprising:

[0070] When the air conditioner is in cooling mode: the condensed water generated by the indoor unit 1 is first evaporated and purified by the condenser 21 of the outdoor unit 2 to obtain primary steam;

[0071] The primary steam is evaporated and purified for the second time through the water vapor conversion component 3 to obtain secondary steam;

[0072] The secondary steam enters the indoor unit 1 through the steam inlet, thereby humidifying the air.

[0073] Evaporation is accompanied by purification, because when water containing impurities is heated, the water can evaporate into water vapor at 100 degrees, and other impurities will not evaporate along with it. Therefore, the evaporation process must be accompanied by purification. In the humidification control method of the air conditioner provided in this embodiment, the condensed water is heated and evaporated by the condenser 21, thereby achieving the first stage of purification of the condensed water, making the humidified water source healthier. The water vapor conversion component 3 is used to achieve the second stage of purification of the condensed water, while making the water droplets evenly atomized, greatly improving the humidification efficiency and humidification effect, and improving the user experience.

[0074] In a specific embodiment:

[0075] The humidification control method of the air conditioner also includes:

[0076] When the air conditioner is in heating state: the water vapor conversion component 3 receives the condensed water produced by the outdoor unit 2, and obtains water vapor after passing through the water vapor conversion component 3;

[0077] The water vapor enters the indoor unit 1 through the steam inlet, thereby humidifying the air.

[0078] In this process, when the condensed water flows into the water vapor conversion component 3 through the pipe 4, it will also partially evaporate. This evaporation is equivalent to the first evaporation purification performed in the condenser 21 during air conditioning cooling. After that, similar to cooling, a second evaporation purification is performed.

[0079] In a specific embodiment:

[0080] When the water vapor conversion assembly 3 includes the semiconductor cooling sheet 312 and the semiconductor heating sheet 322, and the heat of the semiconductor cooling sheet 312 can be transferred to the semiconductor heating sheet 322, and the working state of the semiconductor cooling sheet 312 is controlled by the DC power supply 315:

[0081] Before the water vapor conversion component 3 works, the indoor humidity is detected, and the power applied to the semiconductor refrigeration chip 312 by the DC power supply 315 is controlled by the indoor humidity; specifically, the indoor humidity is negatively correlated with the power applied to the semiconductor refrigeration chip 312 by the DC power supply 315, that is, the lower the indoor humidity, the greater the power applied to the semiconductor refrigeration chip 312 by the DC power supply 315.

[0082] Specifically, the controller also presets the power of the DC power supply 315 corresponding to each indoor humidity. For example, when the indoor humidity detected by the humidity sensor is lower than the humidity threshold, and the absolute value of the difference between the indoor humidity and the humidity threshold is greater than a fixed value, the controller controls the DC power supply 315 to apply a first power to the semiconductor refrigeration chip 312; and when the absolute value of the difference between the indoor humidity and the humidity threshold is not greater than a fixed value, the controller controls the DC power supply 315 to apply a second power to the semiconductor refrigeration chip 312, wherein the first power is greater than the second power.

[0083] In summary, it is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous technical features can be freely combined and superimposed.

[0084] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
