Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a duct-type air conditioner and air conditioning system. Background Technology

[0002] Air conditioners are common household appliances in people's daily lives. Air conditioners are divided into wall-mounted air conditioners and floor-standing air conditioners. An air conditioner usually consists of an indoor unit and an outdoor unit. The indoor unit is installed on the indoor side, and the outdoor unit is installed on the outdoor side.

[0003] In the existing technology, indoor units can be classified into floor-standing indoor units, wall-mounted indoor units, and ducted air conditioners according to their installation method. Among them, ducted air conditioners are widely used because they occupy less effective indoor space.

[0004] However, existing ducted air conditioners (or ducted units) have simple functions, with few additional features besides cooling and heating, which cannot meet the needs of users. Summary of the Invention

[0005] This invention provides a ducted air conditioner and air conditioning system to solve the technical problem that existing ducted air conditioners have limited functions and cannot meet user needs, thereby enriching the functions of ducted air conditioners and improving the user experience.

[0006] This invention provides a ducted air conditioner, comprising: a housing having a return air inlet and an air outlet; a fan disposed within the housing and located at the air outlet; an evaporator disposed within the housing and located at the return air inlet; and an integrated structure disposed within the housing and located between the fan and the evaporator for humidifying the air and cleaning the evaporator.

[0007] In an embodiment of the present invention, the integrated structure includes a humidifier and an evaporator cleaning component connected to the humidifier.

[0008] In an embodiment of the present invention, a drive structure is further included, located inside the housing and connected to the housing and the integrated structure. The integrated structure has a first position and a second position. The drive structure is used to drive the integrated structure to move from the first position to the second position. In the state where the integrated structure is in the first position, the humidifier is used to humidify the air. In the state where the integrated structure is in the second position, the evaporator cleaning component is used to clean the evaporator, and the distance between the humidifier and the evaporator is greater than the distance between the evaporator cleaning component and the evaporator.

[0009] In an embodiment of the present invention, the evaporator cleaning component is located above the humidifier. When the integrated structure is in the first position, the integrated structure is vertical. When the integrated structure is in the second position, the integrated structure is tilted. The tilting direction of the integrated structure is from top to bottom towards the air outlet.

[0010] In an embodiment of the present invention, the drive structure includes a first slide rail, a second slide rail, a motor, a lead screw, and a lead screw nut; the first slide rail is vertically disposed within the housing and located between the fan and the evaporator; the second slide rail is disposed within the housing along the direction from the air outlet to the air return outlet and located between the fan and the evaporator; the motor is disposed within the housing; the lead screw is disposed within the housing along the direction from the air outlet to the air return outlet, and the end of the lead screw is connected to the output shaft of the motor; the lead screw nut is sleeved on the lead screw and connected to the integrated structure.

[0011] In an embodiment of the present invention, the integrated structure has a first side and a second side arranged along its length direction. The first side is provided with a first pulley and a second pulley. When the integrated structure is in a first position, the first pulley and the second pulley are located in a first slide rail. When the integrated structure is in a second position, the first pulley is located in the first slide rail and the second pulley is located in the second slide rail. The second side is provided with a drive shaft, which is connected to the drive shaft by a nut.

[0012] In an embodiment of the present invention, a drive shaft connector is also included. The lower end of the drive shaft connector has a first groove, and the upper end of the nut has a second groove. When the drive shaft is located in the second groove, the drive shaft connector can be disposed on the upper end of the nut to connect the first groove and the second groove, so that the drive shaft can be rotatably passed through the through hole formed by the first groove and the second groove.

[0013] In an embodiment of the present invention, the evaporator cleaning component extends along the length of the integrated structure and has a closed end and an open end. The evaporator cleaning component is gradually narrowed from the open end to the closed end. The open end is used for water inlet. The side wall of the evaporator cleaning component is provided with a plurality of water spray holes. The plurality of water spray holes are evenly spaced from the open end to the closed end. The water spray holes face the evaporator when the integrated structure is in the second position.

[0014] In an embodiment of the present invention, a water curtain is also included, which is disposed inside the housing and located on the side of the evaporator facing the return air inlet. When the integrated structure is cleaning the evaporator, the water curtain covers the return air inlet.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] In the description of this embodiment, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this embodiment and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this embodiment.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this embodiment, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this embodiment, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this embodiment according to the specific circumstances.

[0031] Figures 1 to 7 The ducted air conditioner and air conditioning system provided by the present invention are shown. As can be seen from the figure, the ducted air conditioner of the present invention includes a housing 1, a fan 2, an evaporator 3, and an integrated structure 4. The housing 1 has a return air inlet 112 and an air outlet 111. The fan 2 is disposed inside the housing 1 and located at the air outlet 111. The evaporator 3 is disposed inside the housing 1 and located at the return air inlet 112. The integrated structure 4 is disposed inside the housing 1 and located between the fan 2 and the evaporator 3, and is used for humidifying the air and cleaning the evaporator 3.

[0032] The ducted air conditioner and air conditioning system of the present invention integrates a structure 4 that can humidify the air and clean the evaporator 3. Thus, in addition to cooling and heating, the ducted air conditioner also has the functions of humidifying the air and cleaning the evaporator 3 to meet the needs of users. This solves the technical problem that the existing ducted air conditioners have limited functions and cannot meet the needs of users, enriches the functions of the ducted air conditioner, and improves the user experience.

[0033] like Figure 5 As shown, in an embodiment of the present invention, the integrated structure 4 includes a humidifier 41 and an evaporator cleaning component 42 connected to the humidifier 41. That is, the humidifier 41 and the evaporator cleaning component 42 are connected together.

[0034] In practice, the above-mentioned structural configuration can form a modular design, which can improve the efficiency of loading and unloading the humidifier 41 and the evaporator cleaning component 42.

[0035] like Figure 3 As shown, according to one embodiment of the present invention, the ducted air conditioner of the present invention may further include a drive structure 5, located inside the housing 1 and connected to the housing 1 and the integrated structure 4. The integrated structure 4 has a first position and a second position. The drive structure 5 is used to drive the integrated structure 4 from the first position to the second position. In the state where the integrated structure 4 is in the first position, the humidifier 41 is used to humidify the air; in the state where the integrated structure 4 is in the second position, the evaporator cleaning component 42 is used to clean the evaporator 3, and the distance between the humidifier 41 and the evaporator 3 is greater than the distance between the evaporator cleaning component 42 and the evaporator 3. Figure 3 As shown, integrated structure 4 is located in the second position.

[0036] In practice, the above-mentioned structural arrangement allows the humidifier 41 to be kept away from the evaporator 3 when cleaning the evaporator 3, thereby reducing the splashing of dirt from the surface of the evaporator 3 onto the surface of the humidifier 41.

[0037] It is understandable that since the humidifier 41 and the evaporator cleaning component 42 are connected together, if the position of the humidifier 41 remains unchanged before and after cleaning the evaporator 3, the dirt on the surface of the evaporator 3 will easily splash onto the surface of the humidifier 41 when the evaporator cleaning component 42 cleans the surface of the evaporator 3, causing dirt on the surface of the humidifier 41.

[0038] like Figure 5 As shown, in an embodiment of the present invention, the evaporator cleaning component 42 is located above the humidifier 41. When the integrated structure 4 is in the first position, the integrated structure 4 is vertical. When the integrated structure 4 is in the second position, the integrated structure 4 is tilted. The tilting direction of the integrated structure 4 is from top to bottom towards the air outlet 111.

[0039] In specific implementation, the first position can be the position where the humidifier 41 humidifies the air, that is, the position of the humidifier 41 when the evaporator 3 does not need to be cleaned. The second position can be the position of the humidifier 41 when the evaporator 3 is being cleaned. Since the humidifier 41 is located below the evaporator cleaning component 42 when the integrated structure 4 is in the second position, and the humidifier 41 is farther away from the evaporator 3 when the integrated structure 4 is tilted, dirt on the surface of the evaporator 3 is less likely to splash onto the surface of the humidifier 41.

[0040] Understandably, when the air conditioner compressor stops and the air conditioner enters the self-cleaning mode of the evaporator 3, the angle between the lead screw 54 and the integrated structure 4 can only be an acute angle or a right angle, and cannot be an obtuse angle. This ensures that the evaporator cleaning component 42 (or spray water pipe) of the integrated structure 4 is the part of the entire device closest to the evaporator 3, making better use of water pressure to clean the evaporator 3, and also ensures that the humidifier 41 is far away from the evaporator 3, protecting the humidifier 41 (humidifying fiber) from being contaminated by dirty water.

[0041] like Figure 3 and Figure 6 As shown, according to one embodiment of the present invention, the drive structure 5 may include a first slide rail 51, a second slide rail 52, a motor 53, a lead screw 54, and a lead screw nut 55; the first slide rail 51 is vertically arranged inside the housing 1 and located between the fan 2 and the evaporator 3; the second slide rail 52 is arranged inside the housing 1 along the direction from the air outlet 111 to the air return 112 and located between the fan 2 and the evaporator 3; the motor 53 is arranged inside the housing 1; the lead screw 54 is arranged inside the housing 1 along the direction from the air outlet 111 to the air return 112, and the end of the lead screw 54 is connected to the output shaft of the motor 53; the lead screw nut 55 is sleeved on the lead screw 54 and connected to the integrated structure 4.

[0042] In practice, the rotation of motor 53 can drive nut 55 to reciprocate linearly along the direction from air outlet 111 to air return outlet 112. Since nut 55 is connected to integrated structure 4, nut 55 can drive integrated structure 4 to move between the first position and the second position during the reciprocating linear motion.

[0043] In some embodiments, the duct-type air conditioner of the present invention may further include a limit switch disposed inside the housing 1 and corresponding to the position of the lead screw 54, for controlling the extreme position of the lead screw nut 55.

[0044] like Figure 4As shown, in an embodiment of the present invention, the integrated structure 4 (e.g., humidifier 41) has a first side and a second side arranged along its length direction L. The first side is provided with a first pulley 43 and a second pulley 44. When the integrated structure 4 is in the first position, the first pulley 43 and the second pulley 44 are located in the first slide rail 51. When the integrated structure 4 is in the second position, the first pulley 43 is located in the first slide rail 51 and the second pulley 44 is located in the second slide rail 52. The second side is provided with a drive shaft 45, and a nut 55 is connected to the drive shaft 45.

[0045] like Figure 3 and Figure 7 As shown, according to one embodiment of the present invention, the duct-type air conditioner of the present invention may further include a drive shaft connector 6. The lower end of the drive shaft connector 6 has a first groove 61, and the upper end of the nut 55 has a second groove 551. When the drive shaft 45 is located in the second groove 551, the drive shaft connector 6 can be disposed at the upper end of the nut 55 to connect the first groove 61 and the second groove 551, so that the drive shaft 45 can be rotatably passed through the through hole formed by the first groove 61 and the second groove 551.

[0046] In practical implementation, when it is necessary to install the drive shaft 45, the drive shaft 45 can be placed in the second groove 551 first, and then the drive shaft connector 6 can be installed on the upper end of the nut 55, so that the drive shaft 45 can rotatably pass through the through hole formed by the first groove 61 and the second groove 551. That is, the drive shaft connector 6 and the nut 55 are equivalent to a clamp, which can fit the drive shaft 45. The drive shaft connector 6 can be in the shape of "Ω".

[0047] It is understandable that since the motor 53 is located inside the housing 1, that is, the motor 53 is located inside the housing 1 and connected to the inner wall of the housing 1, the motor 53 is fixed. However, the space of the housing 1 is relatively small, making it inconvenient to move the integrated structure 4 significantly so that its drive shaft 45 can be rotatably inserted into the nut 55. Through the above structural arrangement, the installation difficulty of the drive shaft 45 can be reduced, making the installation of the drive shaft 45 easier.

[0048] like Figure 1 and Figure 2As shown, in some embodiments, the upper end of the housing 1 has a first opening 113 for mounting the first slide rail 51, the second slide rail 52 and the integrated structure 4. The side of the housing 1 has a second opening 114, the position of which corresponds to the drive shaft connector 6. The second opening 114 is used to mount the drive shaft connector 6. When mounting the integrated structure 4, the vertically positioned integrated structure 4 can be inserted downward into the housing 1 through the first opening 113 from the top of the housing 1, so that the first pulley 43 and the second pulley 44 extend into the first slide rail 51, and the drive shaft 45 is located in the first groove 61. Finally, the drive shaft connector 6 is extended into the housing 1 through the second opening 114 and mounted on the upper end of the nut 55, so that the drive shaft 45 can rotatably pass through the through hole formed by the first groove 61 and the second groove 551.

[0049] According to one embodiment of the present invention, the evaporator cleaning component 42 extends along the length direction L of the integrated structure 4 and has a closed end and an open end. The evaporator cleaning component 42 is gradually narrowed from the open end to the closed end. The open end is used for water inlet. The side wall of the evaporator cleaning component 42 is provided with a plurality of water spray holes. The plurality of water spray holes are evenly spaced from the open end to the closed end. The water spray holes face the evaporator 3 when the integrated structure 4 is in the second position.

[0050] In practice, the evaporator cleaning component 42 is gradually narrowed from the open end to the closed end, which can reduce the pressure loss of water and make the water pressure of the water sprayed from the spray holes at both ends of the length direction L of the integrated structure 4 more stable, thereby enhancing the cleaning effect of the evaporator cleaning component 42 and enabling high-pressure rinsing of the surface of the evaporator 3.

[0051] According to one embodiment of the present invention, the duct air conditioner of the present invention may further include a water curtain, which is disposed inside the casing 1 and located on the side of the evaporator 3 facing the return air inlet 112. When the integrated structure 4 is cleaning the evaporator 3, the water curtain covers the return air inlet 112.

[0052] In specific implementation, since the integrated structure 4 is located between the fan 2 and the evaporator 3, when the integrated structure 4 (evaporator cleaning component 42) cleans the evaporator 3, the water spray hole will spray water towards the evaporator 3. Through the above structural setting, the water curtain can be used to cover the return air port 112, thereby preventing the water sprayed from the water spray hole from entering the pipe connected to the return air port 112.

[0053] In some embodiments, the duct-type air conditioner of the present invention may further include a water curtain telescopic structure 7 (or a scissor-type lifting structure), which is disposed inside the casing 1 and located at the return air inlet 112. The water curtain is connected to the water curtain telescopic structure 7, which can extend and retract vertically. That is, the water curtain telescopic structure 7 has an extended state and a folded state. When the integrated structure 4 is cleaning the evaporator 3, the water curtain telescopic structure 7 is in the extended state, and the water curtain covers the return air inlet 112. When the integrated structure 4 is not cleaning the evaporator 3, the water curtain telescopic structure 7 is in the folded state, the water curtain is retracted, and the return air inlet 112 is exposed to connect the return air inlet 112 and the air outlet 111.

[0054] like Figure 6 As shown, in some embodiments, the duct-type air conditioner of the present invention may further include a water receiving tray 8, which is disposed below the evaporator 3, the integrated structure 4 and the water curtain inside the casing 1.

[0055] In practice, the above-mentioned structural design can accommodate the wastewater after cleaning the evaporator 3.

[0056] The present invention also provides an air conditioning system, including at least one of the above-described ducted air conditioners. The specific structure, working principle, and beneficial effects of the ducted air conditioner are the same as those in the above-described embodiments, and will not be repeated here.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0058] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
