The embodiment of the invention provides an air conditioner indoor unit, which comprises a shell, a fan and an evaporator, wherein the shell is provided with an air inlet and an air outlet; also comprises a water receiving tray and a water distributing piece.
The water receiving tray is arranged below the evaporator and used for containing condensed water generated by the evaporator; the water distribution piece is of a capillary structure which can generate capillary phenomenon with water and comprises a water diversion part extending into the water receiving tray to be contacted with the condensed water and an action part positioned in an action area of the fan; the water distributing member guides the condensed water to the acting part through the water guiding part.

And because the action part is positioned in the action area of the fan, the condensed water on the water distribution piece is blown out from the air outlet along with the air flow under the action of the fan, thereby playing the role of humidifying the air by utilizing the condensed water.
By the design, firstly, the problem that the use experience of a user is influenced due to water dripping and water leakage caused by the dripping of the condensed water is solved; secondly, the condensate water is reused for humidifying the air, so that the waste of the condensate water is avoided, the humidity of the air is improved, and the use experience of a user is improved.
Example two
Fig. 1 to 6 show an air conditioner indoor unit, which is a cylindrical cabinet with a cylindrical outline, according to an embodiment of the present invention. The vertical place is on ground during cylinder cabinet-type machine installation, and because of area is little, the air-out coverage area is comparatively identical with human shared space when standing, and novel structure, advantage such as pleasing to the eye receive user's unanimous favor.
The cylindrical cabinet machine comprises a base 3, a shell, a mounting bracket 4, an evaporator 1, a cross-flow fan 6, an air guide piece, a wind sweeping mechanism, a water pan 2 and a water distribution piece 7.
Referring to fig. 1, the base 3 is supported on the ground for supporting the cylindrical cabinet air conditioner, and is provided with an installation structure for installing other components such as a front shell and a rear shell. The lower surface of base 3 is provided with anti-skidding structure usually to make cylinder cabinet-type machine stably support subaerial, guaranteed the stability that cylinder cabinet-type machine supported. In order to facilitate carrying and moving, universal wheels can be convexly arranged on the lower surface of the base 3, so that the cylindrical cabinet machine can move on the ground when necessary. The anti-skid structure is arranged on the base 3 in a telescopic arrangement mode.
The casing is installed in base 3 top, including preceding shell, back shell and top cap. The front shell and the rear shell are combined to form a cylindrical circumferential side face, and a cylindrical central axis formed by combining the front shell and the rear shell is a vertical axis. The top cover covers the top openings mounted to the front and rear housings. The top cover can be manufactured into an integral structure with the front shell or the rear shell, and can also be an independently arranged structure and is installed with the front shell and the rear shell in a threaded fastener, a buckle and other modes.
The front shell is provided with an air outlet, and the rear shell is provided with an air inlet. The air outlet is a vertically extending strip-shaped opening. The air inlet is covered with a grid structure and an air filter screen to prevent impurities in the air from entering the inside of the cylindrical cabinet machine.
The base 3 is a disc-shaped structure which is matched with the shape of the shell. It will be appreciated that to ensure a larger support area, the base plate is designed as a disc structure of larger diameter than the circular shape formed by the combination of the front and rear shells, which are attached to the base 3 with a smooth curved surface. Obviously, when the shape and contour of the casing are changed, the base 3 should be adapted to the change to ensure the reliability of the support and the overall aesthetic appearance, for example, when the indoor unit of the air conditioner is a square cabinet, the shape and contour of the casing are cuboid, and correspondingly, the base 3 is a rectangular disc-shaped structure.
As shown in fig. 3, the mounting bracket 4 is mounted in the housing space above the base 3 by a mounting structure, and includes a pillar 42, an upper mounting seat 41, and a lower mounting seat 43. The upright post 42 extends in the vertical direction, and an upper mounting seat 41 and a lower mounting seat 43 are respectively mounted at the upper end and the lower end of the upright post. The upper and lower mounting seats 41 and 43 are each a horizontally extending structure. The evaporator 1 and the cross flow fan 6 are disposed between the upper mount 41 and the lower mount 43.
The evaporator 1 is arranged at a position close to the air inlet and is a copper tube fin type heat exchanger. As shown in fig. 2, the evaporator 1 includes a plurality of horizontally extending copper pipes arranged in parallel in the height direction. The evaporator 1 extends in the height direction between the upper mount 41 and the lower mount 43. The copper pipe that extends horizontally is the U type structure that the opening gradually enlarges, and the opening of U type structure deviates from the air intake. So design, structural feature and the inner space of make full use of casing increase the heat transfer area of evaporimeter 1, improve heat exchange efficiency. Correspondingly, the air inlet and the air outlet are both vertically extending opening structures corresponding to the evaporator 1. In some variant embodiments, the horizontally extending copper tube is of an arcuate configuration corresponding to the inner wall of the housing.
The cross-flow fan 6 is arranged between the evaporator 1 and the air outlet and drives the air flow to move from the air inlet to the air outlet. Air enters the shell from the air inlet and then passes through the evaporator 1 to be blown out from the air outlet. When the evaporator 1 works, the temperature of the surface of the evaporator changes, and therefore the effect of adjusting the outlet air temperature is achieved. For example, the surface temperature of evaporator 1 is greatly reduced during cooling, and the air flowing across the surface of evaporator 1 exchanges heat with evaporator 1, and the air temperature is reduced accordingly, thereby achieving the effect of reducing the outlet air temperature.
The crossflow blower 6 comprises a crossflow impeller, a volute tongue assembly 5 and an electric motor. The cross-flow impeller is multi-blade type and long cylindrical, and is provided with forward multi-wing blades. The rotation axis of the cross-flow impeller is a vertical axis, two ends of the cross-flow impeller are respectively rotatably mounted on the upper mounting seat 41 and the lower mounting seat 43, and the cross-flow impeller is driven by the motor to drive airflow to move. The motor is a power part of the cross-flow fan 6 and can be supplied with alternating current or direct current.
Referring to fig. 2, the volute tongue assembly 5 is disposed between the evaporator 1 and the air outlet, and is used for guiding the airflow generated by the cross-flow impeller to the air outlet, and has an inlet end facing the evaporator 1 and an outlet end facing the air outlet, and the volute tongue assembly 5 between the inlet end and the outlet end is of a streamlined design. The cross-flow wind wheel is arranged in the volute tongue component 5 and used for driving air at the inlet end to be transferred to the outlet end by high-speed rotation to form wind blown out to the air outlet. The volute tongue component 5 is generally formed by punching a metal sheet and can also be formed by casting plastic or aluminum alloy. In the embodiment, the volute tongue component 5 adopts a streamline design, so that the loss of airflow can be effectively reduced, and the working efficiency of the cross-flow fan 6 is greatly improved.
As can be seen from fig. 2, the cylindrical cabinet in this embodiment is a dual through-flow cabinet including two air outlets, two volute tongue assemblies 5 and two through-flow impellers. Obviously, the present invention is not limited to this, and the cylindrical cabinet may also be a single through-flow cabinet having one air outlet, one volute tongue assembly 5 and one through-flow impeller, or a multi-through-flow cabinet having a plurality of air outlets, a corresponding number of volute tongue assemblies 5 and a corresponding number of through-flow impellers.
And an air guide piece for guiding the airflow generated by the cross flow fan 6 to blow towards the air outlet is arranged between the outlet end of the volute tongue component 5 and the air outlet. The air sweeping mechanism is arranged on the inner side of the air outlet, faces the air outlet and is used for sweeping the air outlet left and right or up and down.
As shown in fig. 1, a water pan 2 is disposed below the evaporator 1, and the water pan 2 is mounted on the lower mounting seat 43 and has a disk-shaped structure for receiving the condensed water on the evaporator 1. It is known that during the cooling process of an air conditioner, moisture contained in the indoor air is condensed and condensed into small water drops on the surface of the evaporator 1 with a low temperature, and thus condensed water is generated. The condensate water can drip after accumulating more to appear leaking or the phenomenon of dripping, influence the refrigeration performance and the use of cylinder cabinet-type air conditioner and experienced, and caused the reduction of indoor air humidity. The water receiving tray 2 can be used for containing condensed water generated by the evaporator 1, so that the phenomenon of water dripping and water leakage caused by the condensed water of the cylindrical cabinet machine is avoided.
Specifically, referring to fig. 3 to 6, the water pan 2 includes a bottom plate structure 21 and a side structure. The bottom plate structure 21 is a horizontally extending plate-shaped structure, and the side structures are arranged around the edge of the bottom plate structure 21 and vertically extend upwards to set the height, so that a container structure capable of containing condensed water is formed. The floor structure 21 may be a regular plate structure, such as a rectangle, trapezoid, circle or diamond, or an irregular plate structure. As shown in fig. 5, the floor structure 21 in the present embodiment has an irregular shape. By the design, the maximum receiving range can be obtained in the limited space inside the shell.
The side plate structure 22 extends in the height direction by a set height to contain a certain amount of condensed water. The extension area of the water pan 2 and the height of the side plate structure 22 jointly determine the water receiving capacity of the water pan 2, and the water receiving capacity can be determined according to factors such as the internal installation space, the power of the air conditioner, the working environment, the size of the evaporator 1 and the like.
It will be appreciated that in order to catch as much condensate as possible that drips from the evaporator 1, the drip tray 2 arranged below the evaporator 1 should be larger than the projection of the evaporator 1 in the horizontal plane. Because the condensed water has light weight and can incline towards the air outlet along with the airflow of the cross flow fan 6 in the dropping process, it is further preferable that the water receiving tray 2 correspondingly has a certain length of extension towards the air outlet.
As shown in fig. 3 to 6, a water distributing member 7 is provided above the water receiving tray 2. The water distribution member 7 is located between the evaporator 1 and the cross flow fan 6 and has a vertically extending rectangular plate-like structure. The bottom end of the water distributing part 7 extends into the water receiving tray 2 and is a water diversion part contacted with the condensed water. The water-introducing portion and the operating portion are used to describe different positions of the water-distributing member 7, and the difference in the structure between the water-introducing portion and the operating portion is not necessarily shown. The opposite larger vertical side surface of the rectangular plate-shaped structure is an expanded surface, and the expanded surface is arranged right opposite to the air inlet.
The water distributing member 7 has a capillary structure capable of generating capillary phenomenon with water. For example, the filter element can be a paper filter element made of chemical fiber filter paper, glass fiber filter paper, wood pulp paper or cotton pulp paper. It is understood that the paper filter element should also include a support structure for supporting chemical fiber filter paper, glass fiber filter paper, wood pulp paper or cotton pulp paper.
The working principle of the water distribution piece 7 is as follows: because the water distributing member 7 is of a capillary structure which can generate capillary phenomenon with water, the condensed water in the water receiving tray 2 rises along the action part from the water guiding part due to the capillary action and is distributed on the action part. And because the action part is positioned in the action area of the fan, the condensed water on the water distribution piece 7 is blown out from the air outlet along with the air flow under the action of the fan, thereby playing the role of humidifying the air by utilizing the condensed water.
By the design, firstly, the problem that the use experience of a user is influenced due to water dripping and water leakage caused by the dripping of the condensed water is solved; secondly, the condensate water is reused for humidifying the air, so that the waste of the condensate water is avoided, the humidity of the air is improved, and the use experience of a user is improved.
The two ends of the water distributing part 7 vertically extend, the bottom end of the water distributing part is positioned in the water receiving disc 2 and is contacted with the condensed water in the water saving disc, and the top end of the water distributing part is close to the upper mounting seat 41. In this embodiment, the bottom end of the water distribution member 7 abuts against the lowest position of the water receiving tray 2, thereby ensuring that the water diversion portion is always in contact with the condensed water.
The water receiving tray 2 is provided with a matching groove with an opening facing the water distribution piece 7, the matching groove is matched with the bottom end of the water distribution piece 7 to limit the water distribution piece 7 to a certain degree, and the water distribution piece 7 is prevented from shaking under the action of the cross-flow fan 6 to influence normal use and normal work of other parts such as the cross-flow fan 6. Obviously, the height of the mating slot should be substantially less than the height of the side panel structure 22.
Referring to fig. 3, the top end of the water distributing member 7 is connected to the upper mounting seat 41 through the lifting device 8. The lifting device 8 is mounted to the upper mount 41 and includes a lifting motor and a lifting mechanism. The lifting mechanism drives the water distributing piece 7 to move up and down under the driving of the lifting motor. The lifting mechanism may be a linear drive mechanism known to those skilled in the art, such as a slider-crank mechanism, a crank-link mechanism, a rack-and-pinion mechanism, etc. The water distributing member 7 is close to or far away from the water receiving tray 2 under the action of the lifting device 8. When the water distributing member 7 is close to the water receiving tray 2 and contacts with the condensed water, the condensed water in the water receiving tray 2 rises upwards along the water distributing member 7 due to the capillary action and is distributed on the unfolded surface. And because the water distribution piece 7 is positioned in the action area of the cross-flow fan 6, and the unfolded surface is opposite to the air inlet, condensed water on the water distribution piece 7 is blown out from the water outlet along with the air flow under the action of the cross-flow fan 6, thereby playing the role of humidifying the air.
When the water distribution member 7 is far away from the water receiving tray 2 and cannot be contacted with the condensed water, the condensed water cannot rise through the water distribution member 7, and the humidification of the air is stopped. Through setting up hoisting device 8, can realize the control to the humidification function, accord with the in-service use demand more.
As shown in fig. 4 and 6, a vertically extending drain post 23 is provided on the floor structure 21 of the drip tray 2. The drainage column 23 comprises an inner column body positioned on the inner side of the water pan 2 and an outer column body positioned on the outer side of the bottom of the water pan 2. The top of the inner side column body is provided with a water drainage hole, the bottom of the outer side column body is provided with a water drainage hole, and the water receiving column further comprises a cavity communicated with the water receiving hole and the water drainage hole. The outer side column body is sleeved with a drain pipe. Through setting up drainage column 23, the outlet is located and sets for the water level height, and when the excessive drainage that reachs the outlet height of condensate water in the water collector 2, discharge through drainage column 23 and drain pipe to avoid the excessive drip that overflows and lead to of condensate water in the water collector 2 and leak. Obviously, the drainage holes can also be arranged at the side of the drainage columns 23, the drainage columns 23 can be arranged at the side plate structures 22, or the drainage holes can be directly arranged at the side structures.
As a deformable embodiment of the water distributing member 7, the water distributing member 7 has a vertically extending columnar structure.
As a deformable embodiment of the water distribution member 7, a plurality of water distribution members 7 are provided between the evaporator 1 and the cross-flow fan 6. As can be appreciated, more water distribution members 7 can improve the humidifying efficiency and the utilization rate of the condensed water in the water pan 2. The water distribution member 7 may also be disposed between the cross flow fan 6 and the air outlet. Usually, a fan action area disposed behind the evaporator 1 is sufficient.

The condensate water can drip after accumulating more to appear leaking or the phenomenon of dripping, influence the refrigeration performance and the use of cylinder cabinet-type air conditioner and experienced, and caused the reduction of indoor air humidity. The arrangement of the water receiving tray can contain the condensed water generated by the evaporator, and the phenomenon of water dripping and water leakage caused by the condensed water of the cylindrical cabinet machine is avoided.
Specifically, the water pan is a V-shaped bucket structure with an opening facing the evaporator. By the design, the maximum receiving range can be obtained in the limited space inside the shell. It will be appreciated that in order to catch as much condensate as possible that drips from the evaporator, the drip tray disposed below the evaporator should be larger than the projection of the evaporator in the horizontal plane.
A water distributing part is arranged above the water receiving tray. The water distribution piece is positioned between the evaporator and the cross-flow fan and is of a plate-shaped structure. The bottom end of the water distribution piece extends into the water receiving tray and is a water diversion part contacted with the condensed water. The larger side of the plate-shaped structure is an expanded surface which is opposite to the inlet end of the volute tongue assembly. It can be understood that, due to the particularity of the internal structure of the wall-mounted indoor unit, the water distribution piece can be bent in the vertical direction corresponding to the inlet end to fully utilize the installation space in order to ensure a larger area of the unfolded surface.
The water distribution piece is of a capillary structure which can generate capillary phenomenon with water. For example, the filter element can be a paper filter element made of chemical fiber filter paper, glass fiber filter paper, wood pulp paper or cotton pulp paper. It is understood that the paper filter element should also include a support structure for supporting chemical fiber filter paper, glass fiber filter paper, wood pulp paper or cotton pulp paper.
The working principle of the water distribution piece is as follows: because the water distribution piece is of a capillary structure which can generate capillary phenomenon with water, condensed water in the water receiving tray rises along the action part from the water guide part due to the capillary action and is distributed on the action part. And because the action part is positioned in the action area of the fan, the condensed water on the water distribution piece is blown out from the air outlet along with the air flow under the action of the fan, thereby playing the role of humidifying the air by utilizing the condensed water.
By the design, firstly, the problem that the use experience of a user is influenced due to water dripping and water leakage caused by the dripping of the condensed water is solved; secondly, the condensate water is reused for humidifying the air, so that the waste of the condensate water is avoided, the humidity of the air is improved, and the use experience of a user is improved.
The bottom of the water distribution piece is abutted to the lowest position of the water receiving tray, so that the water leading part is always in contact with the condensed water. The water receiving tray is also provided with a matching groove with an opening facing the water distribution piece, the matching groove is matched with the bottom end of the water distribution piece to limit the water distribution piece to a certain degree, and the water distribution piece is prevented from shaking under the action of the cross-flow fan to influence normal use and normal work of other parts such as the cross-flow fan. Obviously, the height of the mating grooves should be considerably lower than the height of the side panel structure.
The water collector lateral wall corresponds and sets for the water level height and has seted up the outlet, and the water collector outside is provided with the link with the outlet intercommunication, and the link has cup jointed the drain pipe. Through setting up the outlet, the outlet is located and sets for the water level height, and when the condensate water was too much when reacing the outlet height in the water collector, discharge through the drain pipe to the condensate water that avoids in the water collector excessively spills over the water leakage that drips that leads to.
