Detailed Description

In the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., are based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the device or element being referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present application.

The terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any particular number of features being indicated. Thus, a feature defining "a first", "a second" or the like may include one or more such features explicitly or implicitly. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted", "connected" and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.

The basic functions of the air treatment machine of the application are mainly to adjust the temperature of the air, such as an air conditioner, a refrigerant fresh air machine and the like, and the working principles are as follows: the refrigeration cycle is performed by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged.

The compressor compresses refrigerant gas in a low-temperature and low-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air handler may regulate the temperature of the indoor space throughout the cycle.

The outdoor unit of the air handler refers to a portion of the refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air handler includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The main differences of the air conditioner and the refrigerant fresh air machine are as follows: the air conditioner realizes the circulation of indoor air, and the fresh air of the refrigerant is sent to the indoor after being temperature-regulated by the fresh air machine, so that the temperature of the indoor air can be regulated, and the quality of the indoor air can be improved.

In the following description, a refrigerant fresh air machine is described as an example, but it is understood that the following concepts are equally applicable to an air conditioner.

Referring to fig. 1 to 4, an air handler according to an embodiment of the present application includes: a housing 10 having an air inlet 11 and an air outlet 12, a heat exchanger 40 performing heat exchange with air introduced into the housing 10, and a blower assembly 30 driving air flow.

The housing 10 forms the overall appearance of the air handler, including a chassis 26 forming a bottom structure, a top plate 21 forming a top surface structure, a rear side plate 22 having an air inlet 11, a front side plate 23 having an air outlet 12, a right side plate 24, and a left side plate 25. Among them, the rear side plate 22, the front side plate 23, the right side plate 24, and the left side plate 25 constitute four side walls of the case 10.

The outer surface of the rear side plate 22 can be provided with an air inlet flange 13, the outer surface of the front side plate 23 can be provided with an air outlet flange 14, and the air inlet flange 13 and the air outlet flange 14 are used for connecting air pipes. In the present example, the air inlet flange 13 is formed by flanging the edge of the air inlet 11 outwards, and the air outlet flange 14 is an independent sheet metal part, and is connected to the outer surface of the front side plate 23 corresponding to the air outlet 12. In other examples, the air inlet flange 13 and the rear side plate 25 may be two-piece, and the air outlet flange 14 may be formed by bending the front side plate 23 into a flange.

When the air pipe connected with the air inlet flange 13 extends outdoors and the air pipe connected with the air outlet flange 14 extends indoors, the air processor is a new cooling medium fan, and under the forced driving action of the fan assembly 30, the outdoor new air enters the shell 10 through the air pipe, exchanges heat with the heat exchanger 40, and is sent indoors through the air pipe at the air outlet flange 14.

When the air pipe connected with the air inlet flange 13 extends indoors, and the air pipe connected with the air outlet flange 14 extends indoors, the air processor is an air pipe machine in the air conditioner, under the forced driving action of the fan assembly 30, indoor air enters the shell 10 through the air pipe, exchanges heat with the heat exchanger 40, and then circulates indoors through the air pipe at the air outlet flange 14.

[ Chassis ]

In some embodiments, referring to fig. 5-7, the chassis 26 includes a skeleton 261 and an upper cover plate 262. The frame 261 is formed by connecting a plurality of beams. An upper cover plate 262 is attached to the top end of the frame 26.

The bottom end of the fan assembly 30 abuts against the upper cover plate 262, and on the projection of the top surface of the upper cover plate 262, the bottom surface of the fan assembly 30 coincides with the frame 261, that is, some or all of the bottom surface of the fan assembly 30 is located directly above the frame 261, so that the frame 261 supports the fan assembly 30.

In the prior art, a layer of plate is mostly adopted as a chassis, and when the air processor is hoisted and used, the weight of the fan assembly 30 is completely acted on the chassis. When the fan assembly 30 is larger and heavier, the chassis is easy to deform, and the supporting and bearing functions of the chassis cannot meet the requirements; and if the thickness of the plate is increased, the overall weight of the machine is increased.

In the application, the chassis 26 adopts the structure of the skeleton 261 and the upper cover plate 262, the upper cover plate 262 can ensure the flatness of the wind cavity, and wind resistance caused by uneven bottom surface of the shell 10 when the upper cover plate 262 is omitted is avoided; the frame 261 can increase the load bearing capacity of the chassis 26 without adding too much weight. The structure of the chassis 26 of the present application thus provides the advantage of a highly reliable and lightweight machine.

According to an embodiment of the present application, the frame 261 includes an outer frame 263 and a plurality of support beams 264.

Four beams are connected to each other to form a rectangular outer frame 263, and a plurality of support beams 264 are connected to the inner frame 263. The support beams 264 are provided to carry the fan assembly 30 on the one hand and to strengthen the overall strength of the frame 261 on the other hand.

In the present example, the support beams 264 include four first support beams 265 and two second support beams 266. The four first support beams 265 are parallel and connected with the outer frame 263 at both ends, the first support beams 265 extend in the front-rear direction and are positioned below the fan 31 in the fan assembly 30 and are used for supporting the fan 31; the second support beam 266 extends in the left-right direction, and has one end connected to the first support beam 265 and the other end connected to the outer frame 263, and the second support beam 266 is located below the motor 32 in the fan assembly 30 and is used for supporting the motor 32.

The chassis 26 may further include a lower cover 267 attached to the bottom end of the frame 261. The arrangement of the lower cover plate 267 can strengthen the connection stability of the skeleton, and in addition, can also block air that has permeated into the skeleton 261 from leaking to the outside of the machine.

[ Water pan ]

Referring to fig. 4 and fig. 6 to 9, the chassis 26 is further provided with a water pan 27, and the water pan 27 is located below the heat exchanger 40 and is used for collecting condensed water flowing down on the heat exchanger 40.

For a suction air handler, the heat exchanger 40 is located on the suction side of the fan assembly 30. Therefore, the water pan 27 is located at one side of the frame 261 near the air inlet 11.

Specifically, the rear end of the chassis 26 is provided with a receiving space 260, and the water pan 27 is located in the receiving space 260.

In the current example, two beams at the left and right ends of the frame 261 continue to extend toward the rear ends to form left and right walls of the accommodating space 260, the beams at the rear end of the frame 261 form the front wall of the accommodating space 260, and the rearmost end of the chassis 26 is connected to one beam to form the rear wall of the accommodating space 260.

For convenience of description, a beam at the front end of the receiving space 260 is referred to as a middle beam 260a, and a beam at the rear end of the receiving space 260 is referred to as an edge beam 260b. The lower ends of the middle beam 260a and the edge beam 260b are connected with the reinforcing beam 260c, which can increase the connection strength of the accommodating space 260 and ensure the stability and reliability of the structure.

The chassis 26 further includes a bottom plate 268, the bottom plate 268 covering under the lower cover plate 267 and the accommodating space 260, forming a bottom surface of the chassis 26.

The inner layer (upper surface) of the bottom plate 268 is provided with a sound insulating layer 269 such as felt or the like, which can reduce noise and prevent the seepage of the condensed water from the bottom plate 26.

In the structure of the chassis 26, the parts may be connected by screws or welding.

The upper end of the water pan 27 has a laterally outwardly extending flange which overlaps the top end of the receiving space 260. The top surface of the front end of the water pan 27 is flush with the upper cover plate 262.

With the heat exchanger 40 as a dividing line, a part of the water pan 27 located on the air outlet side of the heat exchanger 40 is a first area, and a part of the water pan 27 located on the air inlet side of the heat exchanger 40 is a second area.

The width of the first region is not less than the width of the heat exchanger 40 in the direction of air flow. In this way, the width of the first area is prevented from being too narrow, so that the air outlet at the lower end of the heat exchanger 40 cannot flow well to the air outlet 12, and the working efficiency of the machine is further affected.

Because the fan assembly 30 is located at the air outlet side of the heat exchanger 40, under the action of the fan assembly 30, water in the water pan 27 is very easy to splash onto the fan assembly 30, so that the normal operation of the fan assembly 30 can be affected.

Thus, in some embodiments of the present application, the water tray 27 is provided with a water baffle 28, and the water baffle 28 covers the first area from the top end of the water tray 27, so that splashing of the condensed water can be prevented.

One end of the water baffle 28 near the air outlet 12 is connected with a side wall (a middle beam 260 a) of the accommodating space 260, and the rear end of the water baffle 28 abuts against the heat exchanger 40.

Specifically, the water baffle 28 includes a water baffle portion 281, and the water baffle portion 281 extends laterally and is located at the top end of the first region to block water from splashing upward.

According to an embodiment of the present application, the water deflector 28 may include a connection portion 282, the connection portion 282 is formed by extending a front end of the water deflector 281 downward, the connection portion 282 abuts against a front sidewall of the water pan 27, and the connection portion 282 and the front sidewall may be connected by welding.

In some embodiments, the water blocking portion 281 is provided with a plurality of louver holes 283, the openings of the louver holes 283 do not face the air outlet 12 side, and the top wall of the louver holes 283 protrudes upward.

Under the fan assembly 30, air under the water guard 28 may flow to the air outlet 12 side through the louver holes 283.

The louver holes 283 are arranged, so that air below the water baffle 28 can continue to flow, water drops can be blocked, and air flowing through the lower part of the heat exchanger 40 is not affected.

The louver holes 283 may be opened toward the heat exchanger side, thus providing a good blocking effect for water droplets.

In some embodiments, the dam 28 may also include a support 284. The support portion 284 is formed by the water blocking portion 281 extending downward. The lower end of the supporting portion 284 is adjacent to or abuts against the water receiving tray 27, so that the water receiving tray 27 can form a support for the rear end of the water blocking portion 281 by the supporting portion 284.

If the support portion 284 is not provided, the water blocking portion 281 has a cantilever structure, and is easily deformed by a force (e.g., air flow blowing), thereby affecting the blocking effect of the water blocking portion 281. Therefore, in the present application, the support portion 284 is provided, and the support portion 284 supports the rear end of the water blocking portion 281, thereby ensuring the overall strength of the water blocking plate 28.

The support portion 284 may be provided at the rearmost end of the water blocking portion 281. The water deflector 28 may be a sheet metal member whose opposite ends are bent downward to form a connection portion 282 and a support portion 284, respectively.

According to an embodiment of the present application, the support 284 is provided with a plurality of flow holes 285. The flow holes 285 allow water to flow through both sides of the support 284.

If the flow holes 285 are not provided, the flow of water in the first region is slow due to the blocking of the support part 284, thereby affecting the collecting effect of the condensed water in the region of the first region located at the front side of the support part 284, and the flow of water at the front side of the support part 284 cannot flow to the rear side to be discharged rapidly when the drip tray 27 discharges water.

Thus, the flow holes 285 provided in the present application ensure the normal water collection and drainage rate of the drip tray 27.

Similarly, if the flow holes 285 are not provided, air passing through the lower end of the heat exchanger 40 cannot smoothly continue to flow toward the air outlet 12 due to the blocking of the support 284, which may affect the working efficiency of the machine. Therefore, the flow holes 285 also function to circulate air, so that the air flow passing through the lower end of the heat exchanger 40 flows to the louver holes 283 through the flow holes 285, and the influence of the support 284 on the air flow is avoided.

The bottom end of the flow holes 285 are opened to avoid the flow of water at the bottom of the first region from being blocked.

The tip of the flow hole 285 exceeds the lateral center line of the support 283. Thus, the flow holes 285 are arranged in the height direction to be relatively high, so that the blocking of water flow can be reduced more, and the water flow efficiency can be improved.

According to an embodiment of the present application, the drain pan 27 is provided with a drain hole 271 for draining condensed water in the drain pan 27.

Drain 271 may be provided in a second region where water from the first region needs to flow back to the second region to drain. The inner bottom surface of the first region is an inclined surface 272, and the inclined surface 272 is inclined from high to low from the air outlet 12 to the air inlet 11 (from front to back). The inclined surface 272 is beneficial to drainage operation, improves drainage efficiency and prevents accumulated water from generating peculiar smell.

The drain holes 271 may be provided one at each of the left and right ends of the water receiving tray 27, and two drain holes 271 further improve the drainage efficiency.

[ sterilizing device ]

Referring to fig. 2, 10 to 12, the air handler may include a UVC sterilizing apparatus 51 provided at an air inlet side of the heat exchanger 40 for sterilizing the heat exchanger 40 and air.

Specifically, the UVC sterilizing apparatus 51 may be connected to the rear panel 22, and a space is formed between the heat exchanger 40 and the rear panel 22, so that a distance is provided between the UVC sterilizing apparatus 51 and the heat exchanger 40, and fewer lamp beads may irradiate the heat exchanger 40.

The UVC sterilization device 51 includes a mounting assembly 511 and a UVC module 512. The UVC module is provided with lamp beads for emitting an ultraviolet light source outwards; the UVC module is connected to the mounting assembly 511, and the UVC sterilization assembly 51 is mounted on the machine by connection of the mounting assembly 511 to the housing 10.

The mounting assembly 511 is typically formed of a metal material. In the related art, the mounting component 511 is connected to the housing 10 by metal contact, and the UVC sterilization device 51 is affected by electromagnetic interference to cause unstable performance.

In the application, the UVC sterilization device 51 is in insulating connection with the shell 10, so that the influence of electromagnetic interference on the performance of the UVC sterilization device 51 can be avoided, and the sterilization effect is ensured.

In some embodiments, the insulating connection between UVC sterilization device 51 and housing 10 is achieved by an insulator 52.

Insulator 52 may be cylindrical in particular. An insulator 52 is attached to the housing 10 and the UVC sterilization device 50 is attached to the insulator 52 to isolate the mounting assembly 511 from the housing 10 by the insulator 52.

The insulator 52 may be connected to the housing 10 by a fastener (e.g., a screw) with a through hole in the middle of the insulator 52 through which the screw is threaded to the housing 10.

The insulator 52 includes a first stopper 521, a stopper 522, and a second stopper 523 in the axial direction. The outer circumference of the limiting body 522 is recessed relative to the stopping body, that is, the outer diameters of the limiting body 522 are smaller than the first stopping body 521 and the second stopping body 523.

The end of the mounting component 511 is provided with a mounting hole 515, and the mounting hole 515 is sleeved on the limiting body 522.

The first stop 521 and the second stop 523 limit the mounting assembly 511, so as to connect the mounting assembly 511 with the insulator 52.

According to an embodiment of the present application, the mounting assembly 511 is provided with a notch 516, one end of the notch 516 is connected to the mounting hole 515, and the opposite end is open.

When assembled, the limiting body 522 is clamped into the mounting hole 515 from the notch 516. The width of the notch 516 is smaller than the outer diameter of the limiting body 522, so that the limiting body 522 can be prevented from falling out of the notch 516.

Both ends in the longitudinal direction of the mounting assembly 511 are mounted to the housing 10 through insulators 52, respectively.

In some embodiments, two mounting holes 515 may be provided at one end of the mounting assembly 511, and correspondingly, two insulators 52.

The two mounting holes 515 are arranged in a vertically opposite mode, the notch 516 at the upper mounting hole 515 is located at the top end, and the notch 516 at the lower mounting hole 515 is located at the bottom end. Specifically, with reference to the circular line of the two mounting holes 515, the notch 516 is located on the extension line of the circular line.

The connection of the two mounting holes 515 may enhance the connection reliability and stability of the mounting assembly 511.

In order not to affect the connection of the ductwork to the intake flange 13, an insulator 52 is provided inside the rear side plate 22. Disassembly and maintenance of the UVC sterilization device 51 within the housing 20 is cumbersome and even requires disassembly of the side panels of the machine.

Thus, in an embodiment of the present application, the mounting assembly 511 includes a mounting stem 513 and two connecting tabs 514. Two connecting pieces 514 are connected to both ends of the mounting lever 513, respectively.

Wherein the UVC module 512 is attached to a mounting bar 513. The mounting assembly 511 is provided in a form of separate connection of the mounting rod 513 and the connecting sheet 514, and only the mounting rod 513 can be detached during maintenance without operating at the insulator 52, thereby improving maintenance convenience.

The connection location of the mounting bar 513 and the connecting piece 514 may be located within the intake flange so that the connection location may be manipulated from the intake 11. In maintenance, the mounting rod 513 is directly detached from the connecting piece 514.

In some embodiments, the connecting tab 514 includes a first tab 517 and a second tab 518. The first sheet 517 is provided with the above-mentioned mounting hole 515 and notch 516, that is, the first sheet 517 is connected to the insulator 52. The second sheet 518 extends from an end of the first sheet 517 in a direction away from the heat exchanger 40.

A gap is formed between the second sheet 518 and the air inlet flange, so that the second sheet 518 is prevented from contacting the air inlet flange.

The connecting piece 514 may include a mounting body 519, where the mounting body 519 is connected to an end of the second sheet 518 remote from the first sheet 517, and the first sheet 517 and the mounting body 519 are respectively located on two sides of the second sheet 518.

The mounting rod 513 abuts against the rear side surface of the mounting body 519, and a fastener (e.g., a screw) is inserted through the mounting rod 513 from the rear side to be connected to the mounting body 519.

The head of the screw faces the air inlet 11, and the screw can be detached from the air inlet 11 during disassembly and maintenance, and the mounting rod 513 can be removed.

The mounting rod 513 may be provided with a U-shaped groove with an opening facing the air outlet 12, and the UVC module 512 is installed in the U-shaped groove; in addition, the mounting body 519 is inserted into the U-shaped groove, and the mounting rod 513 is positioned initially relative to the connecting piece 514 by matching the mounting body 519 with the connecting piece, so that subsequent screwing operation is facilitated.

In the present application, the second sheet 518 extends to the rear side with respect to the first sheet 517, so that the mounting rod 513 is located in the air inlet flange 13 and is as close to the rear side of the housing 10 as possible, which is convenient for maintenance, and avoids the problem that the heat exchanger 40 needs to be disposed to the front side when the UVC sterilizing module 51 is located inside the air inlet 11, thereby increasing the size of the machine in the front-rear direction.

[ Heat exchanger ]

The heat exchanger 40 is disposed within the housing 10 adjacent to the air intake 11 and is located in an air flow path from the air intake 11 to the air outlet 12. The heat exchanger 40 serves to absorb heat from or transfer heat to the air introduced into the air intake 11.

In some embodiments, sealing strips are provided between the two sides of the heat exchanger 40 in the length direction and the housing 10, and between the top surface of the heat exchanger 40 and the housing 10, to achieve a sealed design for the heat exchanger 40, and to prevent air flow from flowing to the fan assembly 30 (from the gap between the heat exchanger 40 and the housing 10) without passing through the heat exchanger 40. Therefore, on one hand, the heat exchange effect is improved, and on the other hand, the condensation can be prevented.

In some embodiments, referring to fig. 3, a support bar 41 is provided between the air intake side of the heat exchanger 40 and the rear side plate 22 of the housing 10 for supporting the heat exchanger 40; in addition, a support bar 41 may be provided between the air outlet side of the heat exchanger 40 and the front side plate 23 of the casing 10.

The supporting bar 41 is positioned at the middle upper part of the heat exchanger 40 in the height direction so as to form a support for the upper part of the heat exchanger 40, prevent the heat exchanger 40 from tilting, and ensure the stability and the firmness of the heat exchanger 40.

One end of the support bar 41 may be connected to end plates of the left and right ends of the heat exchanger 40, and the other end of the support bar 41 is connected to the case 10. The support rods 41 are positioned at the edge of the heat exchanger 40, so that air can not be blocked from flowing through the heat exchanger 40, and the heat exchange performance of the heat exchanger 40 is ensured.

Specifically, the supporting rod 41 is a sheet metal strip, two ends of the supporting rod are bent in opposite directions to form a turned edge, and the supporting rod 41 is approximately in a right-angle Z shape, so that the supporting rod 41 is not easy to deform when being stressed, and the supporting effect of the supporting rod on the heat exchanger 40 is better.

In some embodiments, the air supply opening of the blower assembly 30 is disposed opposite the air outlet 12 for allowing air to flow from the air inlet 11 to the air outlet 12. The air supply of the fan assembly 30 is directly blown to the outside of the machine body, so that the inside of the shell 10 is in a negative pressure area, and thus, the machine body is not easy to leak air outwards, condensation is not easy to generate, and the air leakage and condensation preventing device has the advantages of air leakage prevention and condensation prevention.

In the present example, the air supply end of the fan assembly 30 may be plugged into the air outlet 12. In other embodiments, the air delivery end of the fan assembly 30 may be connected to the air outlet 12, which ensures that the air delivered by the fan assembly 30 is directed out of the machine body.

[ Fan Assembly ]

When the air handler is applied to large places such as shops and office buildings, the power of one fan often cannot meet the use requirement, and thus, in some embodiments of the present application, two fan assemblies 30 are used.

Two air outlets 12 are arranged on the shell 10 in a transverse side-by-side manner, namely a first air outlet 121 and a second air outlet 122. Accordingly, the two fan assemblies 30 are a first fan 301 and a second fan 302, respectively. The first fan 301 corresponds to the first air outlet 121, and the second fan 302 corresponds to the second air outlet 122.

Referring to fig. 13, fig. 13 shows a wind field without a wind separator, when two fan assemblies 30 are simultaneously operated, different rotation speeds are caused by different loads between the fans, and when the rotation speeds are different, the wind field at the heat exchanger is uneven, so that the heat exchange capacity is affected, and the motor with high rotation speed may be operated at an excessive rated power, thereby causing the motor to burn. In addition, uneven wind field also can cause the unstable scheduling problem of unit.

In the present application, therefore, referring to fig. 3 and 14, fig. 14 is a schematic view of a wind field after the wind barrier is provided, and a wind barrier 15 is added between two fan units 30, and the wind field is equalized by the wind barrier 15.

The space in the housing 10 on the air outlet side of the heat exchanger 40 is defined as an air chamber, and the air partition 15 is provided in the air chamber and divides the air chamber into a first air chamber 16 and a second air chamber 17.

The first air outlet 121 is positioned on the side wall of the first air cavity 16, and the first fan 301 is positioned in the first air cavity 16; the second air outlet 122 is located on a side wall of the second air chamber 17, and the second fan 302 is located in the second air chamber 17.

Specifically, the front end of the wind partition 15 abuts against the front side plate 23 of the housing 10, and the rear end of the wind partition 15 abuts or abuts against the heat exchanger 40.

According to the embodiment of the application, referring to fig. 15, a side flange 151 is arranged at one end, close to the air outlet 12, of the air partition plate 15, the side flange 151 abuts against the front side plate 23, and screws penetrate through the front side plate 23 to be connected with the side flange 151.

The bottom end of the wind partition plate 15 is provided with a bottom flanging 152, the bottom flanging 152 is propped against an upper cover plate 262 of the chassis 26, and screws sequentially penetrate through the bottom flanging 152, the upper cover plate 262 and the framework 261.

The holes in the bottom flange 152 through which the screws pass may be formed as waist-shaped holes having a prolate direction identical to the flow direction of air. The provision of the waist-shaped holes enables fine adjustment of the position of the wind separator 15, thereby avoiding misalignment of screw holes due to assembly dimensional tolerances.

In addition, the rollover 151 may be fixed using at least two screws. The screw connection position at the bottom flange 152 is arranged close to the heat exchanger 40, i.e. the screws sequentially penetrate through the waist-shaped holes, the upper cover plate 262 and the middle beam 260a.

The side flanges 151 fix the front end of the wind barrier 15 and the bottom flanges 152 fix the rear end of the wind barrier 15, thereby realizing the secure connection of the wind barrier 15 with minimum screws.

In some embodiments, referring to fig. 16 and 17, the first blower 301 and the second blower 302 are identical in structure, and each includes a fan 31 and a motor 32. The motor 32 is connected to the outside of the fan 31 by a belt transmission.

In the prior art, the fan mostly adopts a structure that the motor is connected inside the fan, and when the power of the fan is larger, the vibration noise generated by the fan is larger because the whole load of the fan is larger.

The motor 32 is connected to the outside of the fan 31, and is driven by belt transmission, so that the load impact of the fan is reduced, the vibration and noise of the unit are reduced, and the hoisting is more stable.

Specifically, the end of the driving shaft of the motor 32 is connected to a driving pulley, the center shaft of the fan 31 extends outward, the end of the center shaft is connected to a driven pulley, and the driving pulley and the loosening pulley are connected by a belt. When the motor 32 is operated, the fan 31 is driven to rotate by the driving pulley through belt transmission.

According to the embodiment of the application, the two sides of the fan 31 are connected with the supporting plates 33, the bottom ends of the supporting plates 33 are propped against the upper cover plate 262 of the chassis 26 and are positioned above the first supporting beams 265, and the supporting effect on the fan 31 is formed by the first supporting beams 265.

The bottom end of the support plate 33 is specifically provided with a lateral edge through which fasteners (e.g., bolts) are sequentially inserted, the upper cover plate 262 and the first support beam 265.

The position of the edge where the bolt is penetrated can be set as a waist-shaped hole, and the prolate direction of the waist-shaped hole is perpendicular to the axis of the fan 31. The position of the fan 31 can be finely adjusted through the waist-shaped hole, so that the air supply end of the fan 31 can be aligned with the air outlet 12.

In the related art, the fan 31 is mostly fixed by a side connection method, that is, the air supply end of the fan is connected with the side wall of the housing, and in the case that the fan is large and heavy, the side connection easily causes the side wall to deform. Therefore, the application adopts the form of bottom connection, which can support the fan 31 as a whole, and the structure of the chassis 26 adopts the skeleton type reinforcing design, thereby ensuring the connection reliability and stability of the shell 10 and the fan 31.

According to an embodiment of the present application, the air conditioner may include a motor base 35, the motor base 35 being coupled to the chassis 26.

Since the fan 31 has a connection relationship with the front side plate 23, in terms of design, the distance from the center of the fan 31 to the front side plate 23 cannot be changed, and if the motor 32 is located on the front side of the axis of the fan 31, the length of the belt is limited; the fan 31 and the heat exchanger 40 have no connection relationship, and the distance between the fan 31 and the heat exchanger 40 can be changed in design, so that the length range of the belt is wider, and therefore, the motor 32 is arranged at the rear side of the axis of the fan 31.

In the left-right direction, the motor 32 is located on the side of the fan 31 away from the wind partition 15, specifically, the motor 32 is located on the right side of the fan 31 in the first fan 301, so that the motor 32 can be maintained by detaching the right side plate 24, and the motor 32 is located on the left side of the fan 31 in the second fan 302, so that the motor 32 can be maintained by detaching the left side plate 25.

Thus, in the present application, the right side plate 24 and the left side plate 25 can be provided to be detachably connected to the housing 10, and the maintenance operation can be performed on the motor 32 in the direction. In other embodiments, a service plate may be provided on the right side plate 24 and the left side plate 25, and the service operation may be performed by removing the service plate.

According to the embodiment of the present application, the motor 32 is connected to the motor base 35 by the mounting bracket 34, and the position of the mounting bracket 34 on the motor base 35 can be adjusted, that is, the mounting bracket 34 has a plurality of mounting positions on the motor base 35, thereby being used for adjusting the distance between the motor 32 and the fan 31 to adapt to the belt requirements of different lengths and adjusting the tension of the belt.

Specifically, the mounting bracket 34 may include a slider 37 and a support bracket 36. The motor 35 is connected to the support 36, and the slide 37 is connected to the bottom of the support 36.

In some embodiments of the present application, the mount 34 is coupled to the motor base 35 by a screw drive.

The slide seat 37 is provided with two lead screws 371 extending forwards and transversely, the lead screws 371 penetrate through the front side wall of the motor base 35, the side wall is called a first limit wall 35a for installation description, at least two nuts are screwed on the lead screws 371, and the two nuts are respectively positioned on two sides of the first limit wall 35 a; the nut located at the front side of the first limiting wall 35a is a distance adjusting nut 381, and the nut located at the rear side of the first limiting wall 35a is a near adjusting nut 382.

The distance adjusting nut 381 abuts against the first limiting wall 35a to limit the movement of the mounting frame 34 to the rear side, and the distance adjusting nut 382 abuts against the first limiting wall 35a to limit the movement of the mounting frame 34 to the front side, so that when both nuts abut against the first limiting wall 35a, the position of the screw rod 371 relative to the motor base 35 is fixed; when the distance between the two nuts is greater than the thickness of the first limiting wall 35a, the mounting frame 34 is loosened relative to the motor base 35, the position of the mounting frame 34 on the motor base 35 can be adjusted by moving the mounting frame 34 along the extending direction of the screw rod 371, and after the adjustment is finished, the nuts are screwed to abut against the first limiting wall 35a, so that the adjustment of the position of the motor 32 is finished.

Illustratively, when the distance between the motor 32 and the fan 31 needs to be increased, the motor 32 needs to be moved backward, and then the remote nut 381 on the front side is screwed to move the remote nut 381 on the front side, then the mounting frame 36 is moved backward, and after the position is adjusted, the two nuts are screwed to the first limiting wall 35 a.

In some embodiments, the motor base 35 is provided with a housing cavity with an open upper end, and the slide 37 is disposed in the housing cavity. A sliding groove 35b is provided on a side wall of the motor base 35 away from the fan 31, and a fastener such as a bolt penetrates through the sliding groove 35b to be connected with the sliding seat 35.

The extending direction of the sliding groove 35b is the front-back direction, which can adapt to different positions of the sliding seat on the motor base 35.

The mounting position of the bolts on the slider 37 may be close to the rear end of the slider 37, so that the rear end of the mounting bracket 34 is prevented from being tilted upward.

When the bolts are unscrewed, the adjustment of the position of the mounting frame 34 is not affected, and when the position is adjusted, the bolts are screwed down again.

The left-right dimension of the accommodating cavity can be matched with the left-right dimension of the slide seat 37, so that when the position of the mounting frame 34 is adjusted in the front-back direction, the accommodating cavity can play a guiding role, and the deformation of the screw rod 371 caused by the inclination of the mounting frame 34 during the movement is avoided.

According to an embodiment of the present application, the front end of the motor base 35 is connected to the second support beam 266 by a screw; the rear end of the motor base 35 is located on the water baffle 28 and can be in threaded connection with the water baffle 28, so that on one hand, the size of the machine in the front-rear direction is more compact, and on the other hand, the motor base 35 plays a lifting role on the water baffle 28, and the water baffle 28 is prevented from being deformed vertically.

According to an embodiment of the present application, the support 36 includes a first support 361 and a second support 362 connected in half. The first support frame 361 and the second support frame 362 enclose a mounting cavity, and the motor 32 is connected in the mounting cavity.

The first support frame 361 supports the left side of the motor 32, and the second support frame 362 supports the right side of the motor 32.

The two-body structure of the support frame 36 can facilitate the installation of the motor 32; compared with a two-body structure which is different, the two-body structure has the advantages that the design and the processing of one part can be reduced, and the cost is saved.

The bottom ends of the first support frame 361 and the second support frame 362 are respectively connected to the slider 37, and the upper ends of the first support frame 361 and the second support frame 362 are connected by a shield case 71 of the reactor 70 (described later).

[ reactor ]

Referring to fig. 16 and 18, since the motor 32 has a vertical dimension much smaller than that of the fan 31, there is an excessive space above the motor 32, and the reactor 70 is connected above the motor 32 in the present application, so that the space can be used. The reactor 70 may also be cooled by the air flow in the case 10.

Compared with the prior art that the size of the electric box is enlarged when the reactor 70 is arranged in the electric box, and the heat generated by the reactor 70 affects other electric components, the application can utilize the fan 31 to radiate the heat of the reactor 71, and the size of the electric box can be smaller after the reactor 70 is separated from the electric box.

According to the embodiment of the application, the reactor 70 can be arranged in the protective box 71, so that the potential safety hazard caused by the exposure of the reactor 70 can be avoided.

Specifically, the shield case 71 is attached to the upper end of the support frame 36. The bottom wall of the protection box 71 is respectively connected with the first supporting frame 361 and the second supporting frame 362 through bolts, so that the connection between the protection box 71 and the supporting frame 361 and the connection between the first supporting frame 361 and the second supporting frame 362 are realized.

A space is provided between the top wall of the support 36 and the motor 32 for the avoidance of bolts.

In some embodiments, the reactor 70 is connected to the bottom wall of the shield case 71 by bolts. An escape groove corresponding to the bolt is provided on the top wall of the support 36 for escaping the bolt.

According to the embodiment of the present application, the front side wall, the left and right side walls and the top wall of the protection box 71 are provided with heat dissipation holes 72 for realizing the ventilation of the inside and outside of the protection box 71 so as to dissipate heat of the protection box 71.

Since the rear side wall of the protection box 71 faces the heat exchanger 40, in order to prevent water drops on the heat exchanger 40 from splashing into the protection box under the action of wind force, the application does not provide the heat dissipation holes 72 on the rear side wall of the protection box 71.

The heat dissipation holes 72 are elongated, so that the area of the protection box 71 can be increased as much as possible while the strength of the protection box is ensured, thereby improving the heat dissipation effect.

In some embodiments, the shield box 71 includes a first shield portion 73 and a second shield portion 74. The first guard 73 and the second guard 74 are both channel-shaped and are joined together in a box shape.

The first guard portion 73 has a first side wall 731 and a second side wall 732 which are opposite to each other, a first stopper portion 733 extending in the direction of the second side wall 732 is provided at both lateral ends of the first side wall 731, and a second stopper portion 734 extending in the direction of the first side wall 731 is provided at both lateral ends of the second side wall 732. The second guard portion 74 is located between the first limit portion 733 and the second limit portion 734.

Illustratively, the first sidewall 731 of the first guard 73 is located at the front side, the second sidewall 732 is located at the rear side, and the first sidewall 731 and the second sidewall 732 form a front-rear limit for the second guard 74; the first limiting portion 733 and the second limiting portion 734 limit the second guard portion 74 in the left-right direction, and positioning of the second guard portion 74 on the first guard portion 73 is achieved.

The bottom end of the second guard 74 is connected to the bottom end of the first guard 73 by a fastener.

Air-out shutter

Referring to fig. 19, the air outlet of fig. 19 has no louver, when the first fan 301 is not operated, the air flow blown by the second fan 302 enters the machine from the first air outlet 121, so that the return air is shorted, and the air flow continues to blow to the first fan 301 to generate a reaction force, so that the motor is burned.

Thus, in the embodiment of the present application, referring to fig. 1, 20 to 22, the air handler further includes a louver 60, and the louver 60 is disposed at the air outlet 12.

The louvers 60 are rotatable when subjected to a force, when the fan assembly 30 is not in operation, the louvers 60 are in a vertical position to close the air outlet 12 (shown in fig. 21), and when the fan assembly 30 is in operation, the louvers 60 are rotated to a horizontal position to open the air outlet 12 (shown in fig. 22).

When the first fan 301 does not operate, the louver 60 closes the first air outlet 31 in a vertical state, so that the air flow blown by the second fan 302 is prevented from flowing into the first air outlet 31, and the phenomenon of air return short circuit is avoided.

According to some embodiments of the application, the louvers 60 are self-hanging louvers. When the self-hanging type shutter is not stressed, the self-hanging type shutter is in a vertical state under the action of dead weight, and when the fan assembly 30 works, the self-hanging type shutter is blown to a transverse state by air flow.

The adoption of the self-hanging shutter structure can omit the electric control arrangement, simplify the product structure and save the cost.

The air handler may include two louvered frames 61. Two shutter frames 61 are connected in the air outlet flange 14 in one-to-one correspondence with two air outlets 12.

The shutter frame 61 has a rectangular frame shape, and can be screwed with the air outlet flange 14. A gasket is provided between the peripheral portion of the louver frame 61 and the housing 10, so that air flow is prevented from returning from the gap between the louver frame 61 and the housing 10.

The plurality of louvers 60 are arranged from top to bottom, and the louvers 60 are rotatably connected in a louver frame 61 through a rotating shaft 62.

In some embodiments, the shutter 60 includes a shutter body 601 and an adapter 602. The switching parts 602 are respectively connected to two ends of the shutter body 601 in the length direction; in the width direction, the joint 602 is close to one end of the shutter body 601 in the width direction, and the rotating shaft 62 is connected to the joint 602.

Because the adaptor 602 is designed to be offset (deviated from the transverse center line) in the width direction of the shutter body 601, the shutter 60 will be in a vertical state under the dead weight effect, and at this time, the rotating shaft 62 is connected with the upper portion of the shutter 60.

A mounting groove 63 with an opening facing the direction of the air inlet 11 can be arranged on the side wall of the shutter frame 61; the side wall of the mounting groove 63 near the center of the shutter frame 61 is defined as a mounting side wall 64, and the rotating shaft 62 is inserted into the mounting side wall 64.

According to the embodiment of the application, the air supply end of the fan assembly 30 is inserted into the shutter frame 60, so that the air supply of the fan assembly 30 is directly blown to the outside of the machine, and the inside of the machine is ensured to be in a negative pressure area. Specifically, the air delivery end of the fan assembly 30 may be inserted into the mounting slot 63.

In some embodiments, stop blocks 65 are provided on the inner side walls of the shutter frame 61, specifically, the stop blocks 65 are provided on the mounting side walls 64.

The stop block 65 is located at the inner side of the louver body 601, and the stop block 64 can be abutted against the louver body 601 in a vertical state, so that the louver 60 is prevented from rotating towards the air inlet 11.

When the first fan 301 does not work, the air flow blown by the second fan 302 flows to the louver 60 at the first air outlet 121, and a backward force is generated on the louver 60, and at this time, the stop block 64 stops the louver 60, so that the louver 60 can be ensured to be in a vertical state to close the first air outlet 121.

The two ends of each shutter 60 in the length direction correspond to one stop block 64 respectively, so that the uniform stop force of the stop block on the shutter 60 can be ensured, and the problem that the shutter 60 is easy to deform when being stopped by only one stop block 64 is avoided.

[ Electrical box ]

Referring to fig. 23-27, the air handler includes an electrical box assembly 80. The electrical box assembly 80 is connected outside the right side plate 24, so that the electrical box assembly 80 can be conveniently and directly maintained without disassembling and assembling the shell 10, and the convenience of maintenance operation is improved.

In other embodiments, the electrical box assembly 80 may also be attached outside the left side plate 25, or the electrical box assembly 80 may be attached inside the housing 10.

In the prior art, the drive plate 84 is typically mounted directly to the electrical mounting plate 82, and the heat sink 842 is screwed from the back to the electrical mounting plate 82, which requires the entire electrical mounting plate 82 to be removed for maintenance of the drive plate 84, which is time consuming and labor intensive.

In the application, the driving plate 84 is connected to the switching mounting plate 83, and the switching mounting plate 83 is connected to the electric mounting plate 82, so that when the driving plate 84 is maintained, the switching mounting plate 83 is only required to be removed from the electric mounting plate 82, the whole electric mounting plate 82 is not required to be disassembled, and the maintenance operation of the driving plate is facilitated.

Specifically, the switching mounting plate 83 is provided with a first avoidance groove 831 for avoiding the driving substrate 841. When the driving board 84 is assembled, the driving board 841 is inserted into the first escape recess 831 from the back surface of the switch mounting board 83, and then the heat sink 842 is screwed from the back surface to the switch mounting board 83.

The electrical mounting plate 82 is provided with an adapter groove 821. When the adapter mounting plate 83 is assembled, the heat sink 842 is inserted into the adapter slot 821 from the front, and the adapter mounting plate 83 is screwed from the front to the electrical mounting plate 82, so that the adapter mounting plate 83 can be directly operated and removed from the front when the drive plate 84 is repaired.

According to the embodiment of the application, the box bottom of the electric box 81 is provided with a second avoidance groove 811 for avoiding the radiator 842. When the electric mounting board 82 is mounted on the electric box 81, the heat sink 842 is inserted into the second escape groove 811. In the assembled state, the heat sink 842 exposes the electrical box 81 from the second escape groove 811.

In some embodiments, the electrical mounting board 82 is spaced from the bottom of the electrical box 81 to accommodate pins of the components, etc.

The adapter mounting plate 83 includes a receiving portion 832 and a burring portion 833. The burring 833 is formed by burring the front side edge of the housing 832, the burring 833 being abutted against the front surface of the electrical mounting plate 82, the housing 832 being inserted from the transit groove 832.

The back surface of the accommodating portion 832 is flush with the inner bottom surface of the electrical box 81, or the back surface of the accommodating portion 832 is located in the second escape groove 811. Since the heat sink 842 is connected to the back surface of the accommodating portion 832, the heat sink 842 can be completely exposed to the electrical box 81, and the heat dissipation effect can be improved.

In some embodiments, a plurality of wire-laying racks 85 are connected to the electrical mounting board 82 for wire laying, so as to ensure that the wires in the electrical box 81 are neat and beautiful.

The wiring groove frame 85 is long. The partial wire groove frame 84 extends along the front-rear direction, and the partial wire groove frame 84 extends along the up-down direction, so that wires in all directions can be considered.

Specifically, the driving board 84 is located at the front side of the electric mounting board 82, and one wiring groove frame 85 is provided on each of the front and rear sides of the driving board 84, and the electric wires can be wired along the wiring groove frame 85 at the front side and then extend from the front side of the electric box 81 to the outside of the electric box 81. Wires between the driving substrate 841 and other substrates may be routed through the backside wire-trace rack 85.

According to an embodiment of the present application, the wire groove 851 is formed on the wire groove frame 85, and the wire groove 851 extends along the length direction of the wire groove frame 85. A clamping groove part 852 is arranged on the groove side wall of the wiring groove 851; from the clamping groove portion 852, the electric wire enters the wiring groove 851.

In some embodiments, a third escape groove 241 is provided on the housing 10. When the electrical box 81 is assembled to the housing 10, the radiator 842 extends into the housing 10 from the third avoiding groove 241, and the radiator 842 can be cooled by the wind power of the fan, so that the cooling effect is further improved.

According to an embodiment of the present application, the side wall of the case 10 is provided with the wire outlet hole 231, and in the present example, the wire outlet hole 231 is provided on the front side plate 23. The electrical box assembly 80 and the inside of the housing 10 can be wired through the wire outlet 231.

A wire outlet cover 291 is connected to the wire outlet hole 231, and the wire outlet cover 291 covers the wire outlet hole 231 and is connected to the front side plate 23. An outlet space is enclosed between the outlet cover 291 and the front side plate 23, and sealing cotton 293 is filled in the outlet space for preventing air leakage at the outlet hole 231.
