Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

An air conditioner 1 according to an embodiment of the present invention is described below with reference to the drawings.

As shown in fig. 1 to 11, an air conditioner 1 according to an embodiment of the present invention includes a case 100, a heat exchanger, a water tray 300, a humidifying device 400, and a drain part 500.

In some embodiments of the present invention, the housing 100 has a receiving cavity 110, a heat exchanger is disposed in the receiving cavity 110, and the water pan 300 is disposed in the receiving cavity 110 and below the heat exchanger. Wherein the housing 100 is disposed to separate the components in the accommodating chamber 110 from the external environment, so as to ensure the stability of the operation of the components in the accommodating chamber 110. When the heat exchanger performs heat exchange operation, a part of condensed water is generated, and the condensed water can be provided to the humidifying device 400, and the humidifying device 400 can perform humidifying operation by using the condensed water generated by the heat exchanger.

In particular, a heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. In the present application, the heat exchanger may be an evaporator, and when the air conditioner 1 is refrigerating, the evaporator may cool the air entering the air conditioner 1, at this time, condensed water may be formed, and the formed condensed water may be collected in the water receiving tray 300 and transported to the humidifying device 400, so as to provide water for humidifying the air for the humidifying device 400, thereby reducing the frequency of adding water to the humidifying device 400 by the user.

In addition, the water receiving tray 300 has a water replenishing opening 310 and a water discharging opening 320, the humidifying device 400 includes a water storage tank 410, the water replenishing opening 310 is connected to the water storage tank 410, and the water discharging opening 320 is connected to the water discharging part 500. When the water storage tank 410 of the humidifying device 400 needs to be replenished, condensed water collected in the water receiving tray 300 can enter the water storage tank 410 through the water replenishing port 310, and thus, automatic water replenishing of the water storage tank 410 can be realized, and the frequency of replenishing water to the water storage tank 410 by a user is reduced. When the amount of water in the water storage tank 410 of the humidifying device 400 is sufficient, the water generated by the heat exchanger can be discharged out of the air conditioner 1 from the water discharge part 500 through the water discharge port 320, so that the water in the water receiving tray 300 is prevented from overflowing the water receiving tray 300 due to excessive water accumulation, and other components in the accommodating cavity 110 are prevented from being damaged.

Therefore, the air conditioner 1 according to the embodiment of the present invention has the advantages of automatically replenishing water to the water storage tank 410, reducing the number of times of artificial water replenishment, and the like.

An air conditioner 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

In some embodiments of the present invention, as shown in fig. 1 to 11, an air conditioner 1 according to an embodiment of the present invention includes a housing 100, a heat exchanger, a water tray 300, a humidifying device 400, and a drain part 500.

In some embodiments of the present invention, the height of the water replenishment port 310 is lower than the height of the water discharge port 320. The arrangement is convenient for accumulating a certain amount of condensed water in the water receiving tray 300, and when water needs to be replenished, the water in the water receiving tray 300 preferentially enters the water storage tank 410 from the water replenishing port 310 so as to replenish the water storage tank 410.

In some optional embodiments of the present invention, the difference between the height of the water replenishing port 310 and the height of the water draining port 320 is 10-20 mm. The arrangement ensures that enough condensed water can be stored in the water receiving tray 300, water can preferentially enter the water replenishing port 310 to replenish water to the water storage tank 410 in the water shortage state of the water storage tank 410, and when the water in the water storage tank 410 is sufficient, part of the water is gathered near the water replenishing port 310, so that the water can be replenished to the water storage tank 410 in time when the water storage tank 410 needs to replenish water again.

Specifically, the height difference between the water replenishing port 310 and the water draining port 320 may be 12-18 mm, and may be 14 mm, 15 mm or 16 mm.

In some embodiments of the utility model, the inner bottom surface of the drip tray 300 has an inclined area 330, and the water replenishing port 310 and the water discharging port 320 are provided in the inclined area 330. The inclined area 330 is convenient for water to flow downwards from the inner bottom surface of the water-receiving tray 300 along the inclined area 330, so that the water in the water-receiving tray 300 can smoothly flow into the water replenishing opening 310 or the water discharging opening 320, and the water in the water-receiving tray 300 is prevented from being left in other areas.

For example, the bottom surface of the water-receiving tray 300 is lower to the left (left and right as shown in fig. 5), the water replenishing opening 310 is lower than the water discharging opening 320, that is, the water replenishing opening 310 is located at the position of the left side of the bottom surface of the water-receiving tray 300, the water discharging opening 320 is located at the position of the right side of the bottom surface of the water-receiving tray 300, and water flows from the right side of the water-receiving tray 300 to the left along the inclined area 330. When the water storage tank 410 needs to be replenished, water in the water receiving tray 300 flows to the leftmost position on the bottom surface of the water receiving tray 300 along the inclined area 330 and flows into the water replenishing opening 310. When the water in the storage tank 410 is sufficient and the water is not required to be replenished, the water may be collected at the leftmost position of the drip tray 300, and when the water level is aligned with the height of the drain port 320 in the left-right direction, the water exceeding the height of the drain port 320 flows into the drain port 320 and is discharged out of the air conditioner 1 through the drain part 500. The arrangement is convenient for gathering water near the water replenishing port 310, and when the water storage tank 410 needs to be replenished, the water can flow into the water storage tank 410 in time to replenish the water storage tank 410.

In some embodiments of the present invention, the storage tank 410 defines a storage chamber 411, and an inlet 413 of the storage chamber 411 is connected to the water replenishing port 310 through a water replenishing pipe 412, and the inlet 413 is located at an upper end of the storage tank 410. That is, the water in the water receiving tray 300 may flow into the water replenishing pipe 412 through the water replenishing port 310 and flow into the water storage chamber 411 from the water inlet 413, and in this way, the water in the water receiving tray 300 is transferred into the water storage chamber 411 to replenish the water storage chamber 411. The water inlet 413 is arranged at the upper end of the water storage tank 410, so that water in the water receiving tray 300 can smoothly flow into the water inlet 413 and enter the water storage cavity 411.

In some optional embodiments of the present invention, the water storage tank 410 is provided with a control valve for controlling the opening and closing of the water inlet 413. When the water in the water storage tank 410 is insufficient, the control valve controls the water inlet 413 to be opened, and at the moment, the water in the water receiving tray 300 and the water replenishing pipe 412 can enter the water storage cavity 411 through the water inlet 413. When the water in the water tank is enough, the control valve controls the water inlet 413 to be in a closed state, at the moment, the water in the water receiving tray 300 can flow into the water replenishing pipe 412, part of the water is gathered near the water replenishing port 310, the water exceeding the water level of the water outlet 320 can flow out from the water outlet 320, therefore, whether water replenishing is carried out or not can be controlled by the control valve, and the water can be timely replenished to the water storage tank 410 by controlling the water inlet 413 to be opened when the water amount in the water storage tank 410 is insufficient.

In some alternative embodiments of the present invention, the water storage tank 410 is provided with a movable float 440, and the float 440 is adapted to control the opening and closing of the water inlet 413 according to the water level in the water storage chamber 411. That is, the float 440 may move up and down according to the change of the water level. The movement of the float 440 can be controlled according to the level of the water in the water storage tank 410, so as to control the opening and closing state of the water inlet 413. For example, when the water in the water storage tank 410 is sufficient, the water level is high, the float 440 blocks the water inlet 413 to seal the water inlet 413, and the water in the water pan 300 and the water replenishing pipe 412 stops entering the water storage tank 410. When the water in the water storage tank 410 is insufficient, the water level is low, the floater 440 is far away from the water inlet 413, at the moment, the water inlet 413 is in an open state, and the water in the water receiving tray 300 and the water replenishing pipe 412 starts to enter the water storage tank 410 to replenish the water in the water storage tank 410.

In some embodiments of the present invention, a guide 450 is provided in the water storage chamber 411, the guide 450 is provided around the water inlet 413 and has a water passing opening, and the float 440 is fitted in the guide 450 to be movable up and down (up and down direction is shown in fig. 1). The guide 450 is provided to limit the movable range of the float 440 so as to control the movement of the float 440 in the up-and-down direction within the guide 450, and the opening or closing of the water inlet 413 can be controlled by adjusting the position of the float 440 with respect to the water passing port.

For example, the guide 450 is formed as a hollow cylinder, the guide 450 has a first sidewall 453, a first bottom 454, a restriction 452, and a water passing port formed at the first sidewall 453, the water storage chamber 411 communicates with the guide 450 through the water passing port, and the first sidewall 453 and the first bottom 454 are connected and define a guide chamber. The float 440 has a float lower body 441 and a float upper body 442. The upper body 442 of the float is formed in a cylindrical shape, the lower body 441 of the float is formed in a cylindrical shape, the upper body 442 of the float has a diameter smaller than that of the lower body 441 of the float, the upper body 442 and the lower body 441 of the float both have axes extending in the vertical direction and are positioned on the same straight line, and since the lower body 441 of the float has a diameter larger than that of the upper body 442 of the float, a first mesa 443 may be formed at the junction of the lower body 441 of the float and the upper body 442 of the float, with the first mesa 443 facing upward.

The float 440 is disposed in the guide chamber, and the axis of the lower body 441 of the float is aligned with the axis of the first bottom surface 454, and extends in the up-down direction, and the side surface of the lower body 441 of the float is in contact with the first sidewall 453 of the guide 450. In which the restriction member 452 is disposed above the float 440, and the restriction member 452 is formed as a circular ring body, that is, the first bottom surface 454 restricts the range of downward movement of the float 440, and the restriction member 452 restricts the range of upward movement of the float 440.

When humidification device 400 utilizes the water in water storage chamber 411 to humidify the air, the water level in water storage chamber 411 reduces gradually, guide 450 passes through the mouth of a river and communicates with water storage chamber 411, the water level in guide 450 also reduces gradually this moment, float 440 moves down, when the position of float 440 is less than the mouth of a river, water inlet 413 is open mode, water storage chamber 411 can pass through mouth of a river and water inlet 413 intercommunication this moment, water in water collector 300 and the moisturizing pipe 412 can flow into in water storage chamber 411 through water inlet 413 this moment, carry out the moisturizing to storage water tank 410. If the water level in the water storage chamber 411 is lower than the first bottom surface 454, the bottom surface of the lower float body 441 contacts the first bottom surface 454, and the float 440 does not move downward. The provision of the guide 450 restricts the position of the float 440 in the water storage chamber 411, which facilitates accurate and timely control of the opening or closing of the water inlet 413 by the float 440.

When the water storage tank 410 is replenished, the water level in the water storage cavity 411 gradually rises, water in the water storage cavity 411 can enter the guide 450 through the water outlet, the float 440 gradually moves upwards due to the action of buoyancy, when the height of the float 440 is higher than the water outlet, the water inlet 413 is in a closed state, at this time, water in the water receiving tray 300 and the water replenishing pipe 412 can not enter the water storage cavity 411 through the water outlet, if a user continues replenishing water to the water storage cavity 411, the water level in the water storage cavity 411 continues to rise, the float 440 continues to move upwards in the guide 450, when the first platform 443 of the float 440 is in contact with the lower surface of the limiting piece 452, the side surface of the upper body 442 of the float is in contact with the limiting piece 452, the float 440 is limited by the limiting piece 452, and does not continue to move upwards, so that reliable sealing is realized. For example, the upper body 442 of the float has a thickness in the up-down direction that is the same as the thickness of the restriction 452 in the up-down direction, which facilitates better cooperation of the float 440 with the restriction 452 for blocking the water inlet 413.

In some embodiments of the present invention, the humidifying device 400 further comprises a sterilization module 420, at least a portion of the sterilization module 420 being disposed within the water storage tank 410. The sterilization module 420 can sterilize the water in the water storage tank 410, so that bacteria generated in the water storage tank 410 are prevented from entering air through the humidification module, and the user is prevented from being injured by the bacteria.

In some optional embodiments of the present invention, the sterilization module 420 is an ultraviolet sterilization module, and the ultraviolet sterilization module is disposed on a sidewall of the water storage tank 410. Ultraviolet sterilization's wide range, fast, and generally can not produce the disinfection accessory substance in aqueous, generally can not produce the quality of water problem, place ultraviolet sterilization module in storage water tank 410's lateral wall, be convenient for make storage water tank 410 internal water all in ultraviolet sterilization module's sterilization scope to the realization is disinfected to the water in the water tank.

In some alternative embodiments of the present invention, the sterilization module 420 is disposed adjacent to the outlet of the water storage tank 410. The water which is often flowable is input or output near the water outlet, and the sterilization device is arranged near the water outlet, so that the sterilization of the water of the normally flowing part is facilitated.

Specifically, the water outlet is located on the bottom wall of the water storage tank 410, water in the water storage tank 410 can enter the spraying component through the water outlet, and the humidifying device 400 is used for processing the water into a water mist device so as to humidify air. The sterilizing device is arranged near the water outlet, and can sterilize the water for humidifying the air in time. Can avoid the bacterium to pass through humidification device 400 and get into in the air, avoid the user to inhale internal harm healthy, can guarantee the cleanliness factor that is used for humidifying air moisture simultaneously to carry out healthy, clear humidification to the air.

In some embodiments of the utility model, the water storage tank 410 is located below the drip tray 300. The water in the water receiving tray 300 can smoothly reach the water storage tank 410 through gravity, so that the water storage tank 410 can be automatically replenished.

In some embodiments of the present invention, the humidifying device 400 includes a spraying part provided at the air outlet 120 of the housing 100 and extending in a height direction of the heat exchanger, and the spraying part is connected to the water storage tank 410. The humidifying device 400 can form water into fine water mist, and the formed water mist is sprayed out through the spraying part and enters the outside air from the air outlet 120 in the air conditioner 1, so as to achieve the effect of humidifying the air.

For example, the humidifying device 400 may be an ultrasonic humidifying device 400 or a thermal evaporation type humidifying device 400, and the ultrasonic humidifying device 400 may atomize water into ultrafine particles of 1-5 μm by using ultrasonic high-frequency oscillation frequency. The heat evaporation type humidifier 400 heats water in a heating body to 100 degrees, and the heated water can generate water vapor. The spraying part has a spraying pipe 430, the spraying pipe 430 extends in the up-down direction and is located at the rear side of the air outlet 120, and the spraying pipe 430 can uniformly spray water mist in the up-down direction and enter the outside air from the air outlet 120 to humidify the outside air.

Specifically, humidification device 400 is arranged in and is held chamber 110, and the heat exchanger is located and holds chamber 110 and can be with inspiratory room air cooling for cold air, holds and still has the wind wheel in the chamber 110, and the wind wheel is used for blowing into in the air with the cold air after the heat exchanger heat transfer and the water smoke that the part of spraying spun from air outlet 120. Wherein the spray pipe 430, the heat exchanger and the wind wheel are all located in the same area of the accommodating chamber 110 and are arranged in the front-back direction (the front-back direction is shown in fig. 1, it should be understood that the above-mentioned directions are only limited for convenience of describing the drawings, and do not limit the actual installation position and direction of the air conditioner 1). The heat exchanger consists of two plates arranged in a V-shaped configuration at an angle, for example, 60 degrees, 90 degrees or 135 degrees. The wind wheel is arranged in front of the heat exchanger and can be positioned on an angular bisector formed by the heat exchange fins, and the wind blowing direction of the wind wheel is forward, so that cold air treated by the heat exchanger can be blown out from the air outlet 120. The spray pipe 430 is located in front of the wind wheel and can be located on an angular bisector formed by the heat exchange fins, and when air is blown out by the wind wheel, water mist sprayed out of the spray pipe 430 can be blown into the outside air together, so that the indoor space is humidified.

In some embodiments of the present invention, the humidifying device 400 in the air conditioner 1 can replenish the water storage tank 410 in two ways, one is to replenish the water storage tank 410 automatically through the water receiving tray 300, and the other is to replenish the water storage tank 410 manually by adding water into the water storage tank 410.

In some embodiments of the present invention, the air conditioner 1 includes a case 100, a heat exchanger, a wind wheel, a water tray 300, a humidifying device 400, and a drain part 500. The housing 100 has a receiving chamber 110 and an air outlet 120 therein, the drip tray 300 has a water replenishing opening 310, a water discharging opening 320 and an inclined area 330, and the humidifying device 400 has a water storage tank 410, a control valve, a float 440, a guide 450, a water outlet, a sterilizing module 420 and a spraying part. The water storage tank 410 defines a water storage chamber 411, the guide 450 has a water passing opening, and the spraying part has a spraying pipe 430. When the air conditioner performs cooling, the heat exchanger performs heat exchange operation, and a part of condensed water is generated, and the part of condensed water can flow into the water receiving tray 300 below the heat exchanger under the influence of gravity, while the inner bottom surface of the water receiving tray 300 is provided with an inclined area 330, and then the water can flow to the lowest part of the inclined area 330, namely the vicinity of the water replenishing port 310. When the humidifying device 400 performs humidifying operation, water in the water storage tank 410 flows out from the water outlet after being sterilized by the sterilizing module 420, the humidifying device 400 atomizes the water flowing out from the water outlet, and the formed water mist is sprayed out from the spraying pipe 430 and is blown into the external environment from the air outlet 120 by the wind wheel. When the humidifying device 400 consumes a portion of water to cause a shortage of water in the water storage tank 410, the water level in the water storage tank 410 is low, the guide 450 and the water storage chamber 411 are communicated through the water passing opening, and the water level in the guide 450 is also low, so that when the float 440 is positioned lower than the water passing opening, water can enter the water inlet 413 through the water replenishing pipe 412 from the water replenishing opening 310 and then flow into the water storage chamber 411 from the water passing opening in the guide 450. At this time, the water level in the water storage cavity 411 gradually rises, the float 440 moves upwards due to the action of buoyancy, when the position of the float 440 is higher than the water outlet, the water in the water receiving tray 300 does not enter the water storage tank 410 any more, but gathers in the water replenishing pipe 412 and near the water replenishing opening 310, if the heat exchanger still performs heat exchange work at this time, the water in the water receiving tray 300 is still gradually increased, the water level in the water receiving tray 300 is gradually increased, and when the water level in the water receiving tray 300 is the same as the height of the water outlet 320, the water exceeding the height of the water outlet 320 can be discharged from the water outlet 320 and discharged from the water discharging part 500.
