Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners, and particularly relates to an outdoor unit of an air conditioner and a split kitchen air conditioner. Background Art

[0002] At present, there are more and more kitchen air conditioner products on the market, and the integrated embedded ceiling type is the mainstream direction. Kitchen ceilings are mostly composed of rows of side-by-side trusses plus aluminum gusset plates of a certain specification. The gap between the trusses is slightly less than 300 mm, and the height inside the ceiling is generally about 400 mm. For an integrated kitchen air conditioner to be placed in this ceiling space, its volume must be made very small, but this will inevitably result in a loss of performance and fail to meet the refrigeration requirements of the kitchen environment. In a related technology, to save space, axial flow fans are used instead of centrifugal fans at both the evaporation and condensation ends of the integrated kitchen air conditioner, and the air pressure is very small, so it is impossible to send air to a suitable position through the air duct. In another related technology, to save space, the centrifugal fans at the evaporation end and the condensation end of the integrated kitchen air conditioner are both external type, and are relatively far from the heat exchanger, resulting in extremely low heat exchange efficiency.

[0003] The split kitchen air conditioner can well solve the contradiction between small size and high performance. In related technologies, this split scheme is also adopted, but it is necessary to drill holes in the exterior wall, introduce outdoor air through pipes, and discharge the air into the flue through pipes. Its essence is an external circulation of heat exchange air. This method is essentially no different from placing the condensation end alone as an outdoor unit, and it is necessary to drill two relatively large air holes in the wall, which is likely to cause dissatisfaction among users. The air inlet of the condensation end is a hole connected to the pipe, the fan is a horizontal single-suction centrifugal fan, and the condenser is a right-angled vertical type. Under this layout, the air inlet area of the condensation end is very small, resulting in more air passing through a section of the condenser close to the air inlet, and almost no air passing through the other right-angled section, and the heat exchange is extremely uneven.

[0004] Since the air inlet of the condensation end of the split kitchen air conditioner in the prior art is a hole connected to the pipe, the fan is a horizontal single-suction centrifugal fan, and the condenser is a right-angled vertical type, only part of the condenser is opposite to the air inlet. Under this layout, the air inlet area of the condensation end is very small, resulting in more air passing through a section of the condenser close to the air inlet, and almost no air passing through the other right-angled section, and there are technical problems such as extremely uneven heat exchange. Therefore, the utility model researches and designs an outdoor unit of an air conditioner and a split kitchen air conditioner. Summary of the Utility Model

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0032] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0033] For the sake of convenience in description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to cover different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0034] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0035] See in conjunction with Figures 1-9As shown in the figure, according to an embodiment of the present utility model, an outdoor unit of an air conditioner is provided, which includes: a main body disposed in the ceiling space of the kitchen. The air inlet 11 of the main body is communicated with the ceiling space. A centrifugal fan and a condenser 12 are disposed in the main body. The air suction port of the centrifugal fan faces the air inlet 11, and an air flow channel is formed between the air suction port of the centrifugal fan and the air inlet 11. The condenser 12 is located in the air flow channel and is directly opposite to the air inlet 11. A first through hole 26 is provided on the main body and is disposed opposite to the centrifugal fan. A first mounting plate 23 is detachably connected to the main body, and the first mounting plate 23 is used to close or open the first through hole 26. Preferably, the air suction port of the centrifugal fan faces the air inlet 11, and the condenser 12 is located between the air suction port and the air inlet 11. Taking the cross-section of the air inlet 11 as the projection plane, the area of the end of the condenser 12 facing the air inlet 11 is not greater than the area of the air inlet 11. In this technical solution, since the condenser 12 is located between the air suction port and the air inlet 11 and the area of the end of the condenser 12 facing the air inlet 11 is not greater than the area of the air inlet 11, the air flow flowing into the air inlet 11 can perform all-round and uniform heat exchange on the condenser 12, improving the heat exchange efficiency of the condenser 12. Further, since the air suction port of the centrifugal fan faces the air inlet 11, the air flow path between the air inlet 11 and the air suction port is greatly reduced, improving the space utilization rate of the main body and reducing the volume of the main body. Through the first through hole 26 and the first mounting plate 23, when after-sales maintenance or replacement of the fan blade and motor is required, only the first mounting plate 23 needs to be opened, and the entire fan component can be taken out through the first through hole 26. The installation action is the opposite, which is convenient and fast.

[0036] Further, the main body is installed in the ceiling space. When after-sales maintenance or replacement of the fan blade and motor is required, only the aluminum gusset of the ceiling needs to be opened, and then the first mounting plate 23 is opened. The entire fan component can be taken out through the first through hole 26. The installation action is the opposite, which is convenient and fast, greatly improving the efficiency and reducing the labor cost.

[0037] The air inlet 11 of the main body is communicated with the ceiling space. Further, the air outlet pipe of the main body can be communicated with the building flue of the kitchen. It can be understood that the air inlet 11 is exposed in the ceiling space, and the air flow flowing into the air inlet 11 is the air in the ceiling space. Of course, the air inlet 11 can also be designed as a ceiling air inlet. The ceiling space is formed by assembling and separating multiple aluminum gussets and corresponding frames in the top area of the kitchen. The positions of some aluminum gussets are designed as ceiling air inlets, that is, the air inlet air flow of the main body all comes from the indoor side, that is, the kitchen space. Further, the central axis of the centrifugal fan volute coincides or is parallel to the central axis of the air inlet 11 to ensure that the air suction port of the centrifugal fan faces the air inlet 11.

[0038] When installing the air conditioner, it is only necessary to dig a ventilation hole in the existing building flue in the kitchen as the exhaust channel of the main body, without the need to dig a corresponding ventilation hole for the intake air of the main body on the building wall, which can meet the relevant regulations of the property management party regarding the building structure modification, and can reduce the installation cost of the air conditioner, with a relatively high user acceptance; on the other hand, the air inlet 11 of the main body can communicate with the ceiling space, so that the air flow in the indoor space cools and dissipates heat from the condenser. Compared with the case of using outdoor air when the external environmental temperature is relatively high, the cooling effect on the condenser is better, so the overall performance of the air conditioner is improved to a certain extent.

[0039] In some embodiments, the centrifugal fan includes a housing 13, the housing 13 has an air suction port and an air outlet, the air suction port is arranged along the axial direction of the housing 13, and the air outlet is arranged along the radial direction of the housing 13. In another embodiment, the housing 13 has an air suction channel, the housing 13 is arranged in the main body, one end of the air suction channel faces away from the air inlet 11, and one end of the air suction channel is in a closed state, and the other end of the air suction channel forms the air suction port. In this technical solution, a centrifugal fan is adopted in the outdoor unit of the air conditioner of the present invention, which greatly reduces the volume of the outdoor unit of the air conditioner. One end of the air suction channel faces away from the air inlet 11, and one end of the air suction channel is in a closed state, and the other end of the air suction channel forms the air suction port. That is to say, the centrifugal fan has only one air suction port, which improves the air suction intensity of the centrifugal fan, so that after the air flow enters the main body from the air inlet 11, it can uniformly and comprehensively exchange heat with the condenser 12, and improves the heat exchange efficiency of the condenser 12.

[0040] In some embodiments, the main body includes a top plate 1, a right side plate 2, a left side plate 3, a front side plate 4, a bottom plate 6 and a rear side plate. The top plate 1, the right side plate 2, the left side plate 3, the front side plate 4, the bottom plate 6 and the rear side plate enclose to form a cavity structure. The air inlet 11 is provided on the top plate 1, and the first through hole 26 and the first mounting plate 23 are provided on the bottom plate 6. In this technical solution, through the bracket 17, the noise generated by the driving member 15 can be greatly reduced. The vibration generated by the driving member 15 is sequentially transmitted to the bottom plate 6 through the mounting plate 16 and the bracket 17. During this process, the mounting plate 16 and the bracket 17 will absorb most of the vibration, thereby reducing the noise generated by the housing 13 and improving the user experience. A plurality of brackets 17 are first fixed on the bottom plate 6, and they can be connected to the bottom plate 6 by screws, spot welding, riveting, or other connection methods. Four compressor positioning bolts are installed at the right side position of the bottom plate 6. To ensure the connection strength, the bracket is made of a sheet metal part, and a screw hole is provided on each bracket. The first mounting plate 23 located above the chassis is fixed to the bracket by screws. The compressor is fixed to the chassis by four compressor positioning bolts. To save space and reduce the external machine housing. The air inlet 11 is provided on the top plate 1. A plurality of neatly arranged openings such as louvers are provided at the place corresponding to the condenser 12 on the left side of the top plate 1 for the air intake of the external machine. The main body is installed in the ceiling space. When maintenance is required, only the aluminum gusset of the ceiling needs to be opened, and then the first mounting plate 23 is opened. The entire fan component can be taken out through the first through hole 26. The installation operation is the opposite, which is convenient and fast, greatly improving the efficiency and reducing the labor cost.

[0041] In some embodiments, a third mounting plate 22 is provided on the bottom plate 6. The third mounting plate 22 is connected to the inner wall of the bottom plate 6 by a plurality of brackets 17. The housing 13 is disposed on the third mounting plate 22. A second through hole 24 is provided on the third mounting plate 22, and the second through hole 24 is disposed opposite to the first through hole 26. A second mounting plate 16 is provided on the third mounting plate 22, and a driving member 15 is provided on the second mounting plate 16. A wind blade 14 is provided on the driving shaft of the driving member 15, and the wind blade 14 is located inside the housing 13. In another embodiment, the second mounting plate 16 can close one end of the air suction channel. In this technical solution, the driving member 15 is a motor, and the motor is fixed to the second mounting plate 16 by a plurality of screws. Then, a centrifugal wind blade, a housing, etc. are installed on its upper part. The centrifugal wind blade is fixed to the rotating shaft of the motor. The lower part of the housing 13 is fixed to the third mounting plate 22. The second mounting plate 16 is fixed to the third mounting plate 22 by screws. The front side surface of the third mounting plate 22 near the air outlet is also fixed to the front side plate installed at the back. After the housing 13 is installed, the upper end surface of the third mounting plate 22 and the inner surface of the housing 13 form an air duct cavity, which together with the centrifugal wind blade and the centrifugal fan form a centrifugal air duct system, realizing an air inlet mode of upward air inlet and a side air outlet air path form. The front and rear sides of the condenser 12 are respectively fixed to the corresponding positions of the left side plate and the front side plate installed at the back through the condenser side plates thereon.

[0042] In order to save the mold opening cost and speed up production, shell parts such as the bottom plate, left side plate, right side plate, front side plate, top cover, etc. are all designed as sheet metal numerical control parts.

[0043] In some embodiments, the diameter of the first through hole 26 is larger than the diameter of the second mounting plate 16. The second mounting plate 16 can close or block the second through hole 24, and the wind blade 14 can sequentially pass through the first through hole 26 and the second through hole 24. In this technical solution, a first through hole 26 with a diameter of φ4 is left at the middle position of the bottom plate 6, and its size can at least pass through the second mounting plate 16 described below. The diameter of the second mounting plate 16 is φ3, and it is used to pass the pre-assembled fan component through this hole. A second through hole 24 with a diameter of φ2 is left at the middle position of the third mounting plate 22, and its size can at least pass through the centrifugal wind blade described below. The diameter of the centrifugal fan is φ1.

[0044] The fan component mainly consists of components such as the second mounting plate 16, motor, motor fixing screws, wind blade 14, wind blade fixing nuts, etc. Before the overall machine assembly, the fan component is pre-assembled first. When pre-assembling the fan component, first fix the motor to the second mounting plate 16 by a plurality of screws, and then install a centrifugal wind blade on its upper part. The centrifugal wind blade 14 is fixed to the rotating shaft of the motor by a wind blade fixing nut.

[0045] When installing the centrifugal fan, fix the lower part of the housing 13 on the third mounting plate 22 fixed on the bottom plate 6, and also fix the front side of the housing 13 near the air outlet to the front side plate 4 installed at the back. After installing the housing 13, the pre-assembled fan components sequentially pass through the first through hole 26 and the second through hole 24, and fix the motor mounting plate on the second mounting plate 16 through a number of fan component fixing screws, thereby fixing the fan components on the second mounting plate 16. At this time, the upper end surfaces of the second mounting plate 16 and the third mounting plate 22 and the inner surface of the housing 13 form an air duct cavity, which together with the centrifugal impeller and the fan forms a centrifugal air duct system, realizing an air inlet mode of upward air inlet and a side air outlet air path form.

[0046] The first mounting plate 23 is fixed on the bottom plate 6 through a number of screws. The diameter of the first mounting plate 23 is φ5. The first mounting plate 23 has the functions of beautifying the appearance of the housing, strengthening the strength of the housing, and sealing the internal parts of the housing to prevent oil fumes, dust, etc. The first mounting plate 23 can be an injection molded part or a sheet metal part. A card slot can be set on the bottom plate 6, and a buckle 25 can be set on the first mounting plate 23, and the first mounting plate 23 is fixed on the bottom plate 6 by the cooperation of the buckle 25 and the card slot.

[0047] Furthermore, the first mounting plate 23 can also adopt a structure of one screw and a number of buckles 25, which has a simple structure, high installation efficiency and low cost. During installation, align a number of buckles with the mounting hole positions on the corresponding chassis, rotate a certain angle, and then fix one screw.

[0048] Furthermore, in order to meet the operations such as installation and after-sales maintenance, the diameters of each part are set as: φ1 < φ2 < φ3 < φ4 < φ5. The diameter of the second mounting plate 16 is φ3, the diameter of the first through hole 26 is φ4, the diameter of the second through hole 24 is φ2, and their sizes can be at least determined by the following centrifugal impeller 16. The diameter of the centrifugal fan is φ1, and the diameter of the motor baffle is φ5.

[0049] Furthermore, in order to better dissipate heat from the fan, heat dissipation holes, slots, etc. can also be provided on the first mounting plate 23.

[0050] Furthermore, since the main body is placed in a relatively enclosed kitchen ceiling space with less dust, the first mounting plate 23 and its attached fixing screws can also be directly removed, thereby further increasing the heat dissipation of the motor and making it more convenient for after-sales maintenance and replacement of the fan components.

[0051] In some embodiments, an air outlet duct 5 is provided on the front side plate 4. The air outlet duct 5 is communicated with the air outlet of the centrifugal fan. A compressor 18 is further provided in the main body. The compressor 18 is arranged in parallel with the centrifugal fan, and the axis of the compressor 18 is parallel to the central axis of the air outlet duct 5. In this technical solution, the air outlet of the air outlet duct 5 can be communicated with the building flue of the kitchen. The air outlet duct 5 discharges the heat-exchanged air flow into the building flue. That is, only a wind hole needs to be dug in the building flue for the air outlet of the outdoor unit of the air conditioner in the present utility model, reducing the installation difficulty. A compressor 18 is further provided in the main body. The compressor 18 is arranged in parallel with the centrifugal fan, and the axis of the compressor 18 is parallel to the central axis of the air outlet duct 5. The compressor is a horizontal compressor, that is, the axial direction of the compressor cylinder block is the front-back direction of the outer machine housing. The space inside the main body is reasonably utilized, thereby reducing the volume of the main body and facilitating the installation of the air conditioner.

[0052] In some embodiments, the rear side plate includes a first side plate 7 and a second side plate 8. The centrifugal fan is opposite to the first side plate 7, and the compressor 18 is opposite to the second side plate 8. An electrical box 19 is provided in the main body.

The wiring terminals of the compressor 18 are close to the rear of the compressor, so as to facilitate electrical connection with the electrical box components provided at the right rear of the compressor. It is convenient for after-sales installation, maintenance, etc. It is easy to disassemble for repairing the main board, wiring or components in the internal electrical box 19.

[0053] In some embodiments, a plurality of wire passing holes 20 are provided on the rear side plate. The wire passing holes 20 are located near the compressor. A valve body 21 is further provided on the rear side plate. In this technical solution, specifically, the wire passing holes 20 are provided on the second side plate 8.

A suspension rod 9 is provided on each fixing part 10, and the main body is hoisted at the top area of the ceiling space through the suspension rod 9. In this technical solution, a plurality of fixing parts 10 are provided on the outer wall of the main body, and a suspension rod 9 is provided on each fixing part 10. First, a plurality of suspension rods 9 are fixed to the fixing parts 10. Preferably, the fixing parts 10 are installed on the left side plate and the right side plate, and the connection can be by screw connection, spot welding connection, riveting connection, or other connection methods. The fixing part 10 can adopt a hook, and the lower end of the suspension rod 9 required for installing the outer machine main body is fixed to the hook with a nut. An expansion bolt is provided at the upper end of the suspension rod 9, which is fixed to the ceiling of the kitchen for hanging the entire outer machine housing.

[0055] In some embodiments, the condenser 12 adopts a flat plate structure, and there is a distance h between the condenser 12 and the air inlet 11, which satisfies 100mm ≥ h ≥ 20mm. In this technical solution, the condenser 12 adopts a flat plate structure, that is to say, the condenser 12 is in a flat plate shape, so that the space occupied by the condenser 12 is greatly reduced. Further, there is a distance h between the condenser 12 and the air inlet 11, which satisfies 100mm ≥ h ≥ 20mm. While ensuring that the air inlet 11 can evenly introduce the air flow in the ceiling space into the centrifugal fan, it can also make the air inflow on the heat dissipation surface of the condenser 12 relatively uniform, and the heat exchange is more uniform and the effect is better.

In this technical solution, the indoor unit of the air conditioner and the outdoor unit of the air conditioner are in refrigerant communication with each other's evaporators and condensers through refrigerant pipes. Of course, corresponding cables are also provided between the two to achieve electrical connection. Except for the connection formed by the foregoing refrigerant pipes and cables, there is no other direct contact between the indoor unit of the air conditioner and the outdoor unit of the air conditioner in terms of physical structure. The foregoing indoor unit of the air conditioner and outdoor unit of the air conditioner are respectively hoisted at the top area of the ceiling space through corresponding suspension rods 9, and both the indoor unit of the air conditioner and the outdoor unit of the air conditioner are arranged in the ceiling space of the kitchen.

[0058] Below the ceiling is the kitchen working space. Air circulation between the ceiling and the kitchen is carried out through the air intake panel and the air supply panel, with a flexible position and can be installed and arranged according to actual needs. One corner of the ceiling is the building flue, and the kitchen fumes and the hot air after heat exchange of the outdoor unit of the air conditioner can be discharged into the building flue through the air outlet pipe 5.

[0059] The indoor unit and the outdoor unit of the split kitchen air conditioner are respectively suspended on the ceiling by multiple suspension rods 9, and the appropriate positions can be freely selected for layout. The kitchen ceiling space is usually very narrow, and there are pipes with unknown lines and building beams arranged, so the installation is full of uncertainties. The small-sized outdoor unit and indoor unit of the split type well solve this problem, can make full use of the spare space, adopt the principle of proximity, adapt to local conditions, and are flexible and convenient. At the same time, compared with the integrated layout, the exhaust pipe and the air supply pipe of the split kitchen air conditioner can be closer to the exhaust port and the air supply port, shortening the pipe length, greatly increasing the air volume of the indoor unit of the air conditioner, and improving the performance.

[0060] It is easy for those skilled in the art to understand that, on the premise of no conflict, the advantageous technical features of the above-mentioned various methods can be freely combined and superimposed.

[0061] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
