Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a vertical air conditioner. Background Art

[0002] In North America, most household air conditioners are vertical air conditioners, which are mainly composed of a heat exchanger and a centrifugal fan. This type of air conditioner mainly uses a centrifugal fan to blow air into the user's room. The motor of the centrifugal fan is generally fixed on the side of the fan volute. There are two air inlets on both sides of the centrifugal fan, and the motor will extend into one of the air inlets.

[0003] Since the diameter of the motor is relatively large, the cross-sectional area of ​​the motor occupies almost 50% to 70% of the area of ​​an air inlet. In this way, the net value of the air inlet area is greatly reduced, and the air volume passing through this air inlet will be greatly reduced, resulting in a reduction in the air output of the entire indoor unit.

[0004] At the outlet of the vertical air conditioner, an electric heating component for heating is installed. Since the motor is installed on the side of the volute, it will block the air inlet, resulting in a small air volume at the outlet of the vertical air conditioner. The electric heating wire cannot dissipate heat in time, which will cause a red-hot problem. After long-term use, it may overheat and burn, and the surface of the electric heating wire will oxidize and turn black, affecting the service life of the electric heating component.

[0005] In addition, the motor is set at the air inlet of the centrifugal fan, and the motor will generate more heat when working. Under refrigeration conditions, the cold and warm air flow meet, which is easy to cause condensation near the motor volute.

[0052] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0053] The vertical air conditioner is connected by a pipeline to transmit refrigerant, and the vertical air conditioner includes an indoor heat exchanger and an indoor fan. The outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan and an expansion valve. The compressor, the outdoor heat exchanger, the expansion valve and the indoor heat exchanger connected in sequence form a refrigerant circuit, and the refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger and the indoor heat exchanger respectively, so as to realize the cooling mode or heating mode of the indoor unit of the ducted air conditioner. The outdoor heat exchanger is configured to perform heat exchange between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger.

[0054] For example, the outdoor heat exchanger works as a condenser in the cooling mode of the indoor unit of the ducted air conditioner, so that the refrigerant compressed by the compressor dissipates heat to the outdoor air through the outdoor heat exchanger and condenses. The outdoor heat exchanger works as an evaporator in the heating mode of the indoor unit of the ducted air conditioner, so that the decompressed refrigerant absorbs heat from the outdoor air through the outdoor heat exchanger and evaporates.

[0055] In some embodiments, the outdoor heat exchanger also includes heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant. The outdoor fan is configured to suck the outdoor air into the outdoor unit through the second air inlet of the outdoor unit, and send the outdoor air after heat exchange with the outdoor heat exchanger through the third air outlet of the outdoor unit. The outdoor fan provides power for the flow of outdoor air. The expansion valve is connected between the outdoor heat exchanger and the indoor heat exchanger, and the opening size of the expansion valve regulates the refrigerant pressure flowing through the outdoor heat exchanger and the indoor heat exchanger to regulate the refrigerant flow between the outdoor heat exchanger and the indoor heat exchanger. The flow and pressure of the refrigerant circulating between the outdoor heat exchanger and the indoor heat exchanger will affect the heat exchange performance of the outdoor heat exchanger and the indoor heat exchanger.

[0056] The expansion valve may be an electronic valve. The opening of the expansion valve is adjustable to control the flow and pressure of the refrigerant flowing through the expansion valve. The air conditioner further includes a control device. The control device is configured to control the operating frequency of the compressor, the opening of the expansion valve, the speed of the outdoor fan, and the speed of the indoor fan. The control device is connected to the compressor, the expansion valve, the outdoor fan, and the indoor fan via a data line to transmit communication information. The control device includes a processor. The processor may include a central processing unit (CPU), a microprocessor, an application specific integrated circuit (ASIC), and may be configured to perform the corresponding operations described in the control device when the processor executes a program stored in a non-transitory computer-readable medium coupled to the control device. The non-transitory computer-readable storage medium may include a magnetic storage device (e.g., a hard disk, a floppy disk, or a tape), a smart card, or a flash memory device (e.g., an erasable programmable read-only memory (EPROM), a card, a stick, or a keyboard drive).

[0057] Reference below Figure 1-Figure 20 A floor-type air conditioner 100 according to an embodiment of the present invention is described.

[0058] like Figure 1 and Figure 8As shown, a vertical air conditioner 100 according to an embodiment of the present invention includes: a housing 10, a heat exchanger 20 and a fan assembly 30. A chamber is formed in the housing 10, an air outlet 11 is arranged at the top of the housing 10, and the heat exchanger 20 is arranged at the lower part of the chamber. After the air in the chamber is heat exchanged by the heat exchanger 20, it flows into the room from the air outlet 11 under the action of the fan assembly 30.

[0059] The heat exchanger 20 is arranged at the lower part of the chamber, and the fan assembly 30 is arranged above the heat exchanger 20. An air duct can be formed in the chamber of the housing 10, and the air entering the chamber is firstly heat-exchanged through the heat exchanger 20, and the fan assembly 30 delivers the hot air or cold air after heat exchange to the air outlet 11 at the top of the housing 10 through the principle of negative pressure air supply, so as to adjust the indoor temperature.

[0060] The fan assembly 30 includes: a duct member 31, a fan 32 and a motor 33. The duct member 31 is arranged at the upper part of the chamber. An air inlet 311 is formed on at least one side of the duct member 31, and an air supply port 312 is arranged on the top of the duct member 31. The air supply port 312 is arranged opposite to the air outlet 11.

[0061] The air inlet 311 can be provided on both the left and right sides of the air duct member 31, so that the air intake volume can be increased, thereby increasing the air outlet volume, and further improving the air outlet efficiency of the vertical air conditioner 100. The air entering from the air inlet 311 of the air duct member 31 is transported to the air outlet 312 by the fan 32, which can increase the air flow rate, and the air from the air outlet 312 is then discharged from the air outlet 11 at the top of the housing 10, thereby improving the air outlet speed of the vertical air conditioner 100.

[0062] The fan 32 is disposed in the air duct member 31. The air after heat exchange by the heat exchanger 20 enters the air duct member 31 from the air inlet 311, and flows from the air supply port 312 to the air outlet 11 under the action of the fan 32. The fan 32 has a fan shaft 321, and the motor 33 has a motor shaft 331. The motor shaft 331 is transmission-connected with the fan shaft 321, so as to drive the fan 32 to rotate.

[0063] The motor shaft 331 is connected to the fan shaft 321 , and the motor 33 drives the fan 32 to rotate, which can increase the rotation speed of the fan 32 and the air supply volume, thereby improving the air supply efficiency.

[0064] In addition, the motor 33 is arranged outside the housing 10 , and a first through hole 12 is arranged on the housing 10 . The motor shaft 331 passes through the first through hole 12 and is drivingly connected to the fan shaft 321 , so that the motor 33 can avoid the air inlet 311 .

[0065] Specifically, the motor 33 of the existing fan 32 is generally fixed on the side of the air duct member 31. Since the diameter of the motor 33 is relatively large, the cross-sectional area of ​​the motor 33 almost occupies 50% to 70% of the area of ​​the air inlet 311, so that the net value of the area of ​​the air inlet 311 is greatly reduced, and the air volume passing through the air inlet 311 will be significantly reduced, which will cause the air volume of the entire vertical air conditioner 100 to be reduced.

[0066] Therefore, it is necessary to optimize the arrangement position of the motor 33 in the air duct member 31 .

[0067] Specifically, Fig. 9 As shown, the motor 33 is arranged outside the housing 10, and the motor 33 can be arranged on the left or right side of the housing 10. In this way, the motor 33 can avoid blocking the air inlet 311 on the air duct member 31, and the air inlet area of ​​the air inlet 311 can be increased, so that the air inlet volume at the air inlet 311 is increased, thereby increasing the air outlet volume of the vertical air conditioner 100. The motor shaft 331 is arranged to pass through the first through hole 12 on the housing 10, and the housing 10 can separate the motor 33 from the fan 32, and the air inlet area at the air inlet 311 can be fully guaranteed.

[0068] Furthermore, compared with the conventional arrangement of the motor 33 at the air inlet 311 of the air duct member 31, the motor 33 generates more heat when working. Under refrigeration conditions, cold and warm flows meet, and condensation is likely to occur near the air duct member 31 of the motor 33. The condensation water near the air duct member 31 of the motor 33 is likely to enter the electric control area, causing a short circuit risk to the electric control components.

[0069] The motor 33 is arranged outside the housing 10 so that the motor 33 will not be affected by the condensed water, thereby increasing the service life of the motor 33 and avoiding interference between the motor 33 and the fan 32 .

[0070] In addition, the motor 33 installation module can be stored in the cavity space of the air conditioner, without taking up additional packaging space, having no effect on the packing volume for sea transportation, and not increasing the transportation cost. Under the same speed, since the blocking area of ​​the air inlet 311 of the air duct member 31 is greatly reduced, the air intake volume can be significantly increased.

[0071] Moreover, under the condition of the same air volume requirement, the power used by the motor 33 can be reduced, and the energy consumption can also be reduced.

[0072] Thus, the motor 33 is arranged outside the housing 10, so that the motor 33 can avoid blocking the air inlet 311 on the air duct member 31, and the air inlet area of ​​the air inlet 311 can be increased, so that the air inlet volume at the air inlet 311 is increased, thereby increasing the air outlet volume of the vertical air conditioner 100. Moreover, the motor 33 will not be affected by condensed water, so that the service life of the motor 33 can be increased.

[0073] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, the vertical air conditioner 100 further includes: a mounting bracket 40 , the mounting bracket 40 surrounds the outer circumference of the motor 33 , the mounting bracket 40 is disposed outside the casing 10 , and the mounting bracket 40 is fixedly connected to the casing 10 .

[0074] The mounting bracket 40 is fixedly connected to the outer periphery of the motor 33 , and the motor 33 is fixed to the left or right side of the housing 10 through the mounting bracket 40 , so that the motor 33 can be fixed more stably and firmly.

[0075] According to some embodiments of the present invention, Figure 5 As shown, the mounting bracket 40 includes: a plurality of external clamps 41, mounting legs 42 and a second fastener 44. The plurality of external clamps 41 surround the outer peripheral side of the motor 33, and adjacent external clamps 41 are fixedly connected by the first fastener 43. One end of the mounting leg 42 is arranged between the external clamp 41 and the outer peripheral side of the motor 33, and the other end of the mounting leg 42 is provided with a shock-absorbing pad 45. The second fastener 44 passes through the other end of the corresponding mounting leg 42 and the shock-absorbing pad 45 and is fixedly connected to the housing 10.

[0076] Specifically, one end of the mounting foot 42 is connected between the motor 33 and the external clamp 41, and the outer peripheral side of the motor 33 and the external clamp 41 can clamp and fix the mounting foot 42, so that the mounting foot 42 can be connected more stably. Adjacent external clamps 41 are fixedly connected by the first fastener 43, which can facilitate disassembly and installation.

[0077] Moreover, if Figure 6 As shown, a shock-absorbing pad 45 is provided at the other end of the mounting foot 42. The shock-absorbing pad 45 is in contact with the housing 10, and can attenuate the vibration transmitted from the motor 33 to the housing 10, and can prevent the motor 33 from vibrating the housing 10 during operation, thereby ensuring the stability of the vertical air conditioner 100 during operation.

[0078] In addition, the shock-absorbing pad 45 is engaged with the circular hole at the other end of the mounting leg 42 to make the engagement more tight. Further, the other end of the mounting leg 42 is fixed to the housing 10 by a second fastener 44 .

[0079] Specifically, the second fastener 44 is inserted into the circular gasket, the shock-absorbing pad 45 and the housing 10 in sequence. The second fastener 44 can be a hexagonal screw. One end of the second fastener 44 that is inserted into the housing 10 is screwed and fixed with the blind hole nut to prevent the connection between the mounting foot 42 and the housing 10 from loosening. Moreover, the blind hole nut can be welded on the housing 10, which can further make the connection between the mounting foot 42 and the housing 10 more stable and firm.

[0080] On the side of the housing 10 where the motor 33 is not installed, a separate plug is no longer needed to seal the nut hole on the housing 10, and the blind hole nut is used for packaging, which can play a role in sealing and heat preservation.

[0081] Furthermore, if Figure 6 As shown, the mounting foot 42 is L-shaped, and the mounting foot 42 can be an integrally formed sheet metal part. The mounting foot 42 is provided with a protrusion structure of different shapes and sizes. The setting of the protrusion structure can not only enhance the strength of the mounting foot 42, but also reduce the frequency of vibration between the mounting foot 42 and the housing 10, thereby ensuring the stability of the connection between the mounting foot 42 and the housing 10.

[0082] According to some embodiments of the present invention, Figure 9-11 As shown, the vertical air conditioner 100 also includes: a seat plate 50 and a bearing 60. The seat plate 50 is arranged in the chamber. An installation cavity is formed between the seat plate 50 and the casing 10. The bearing 60 is arranged in the installation cavity. The motor shaft 331 passes through the first through hole 12 and the bearing 60 in sequence.

[0083] The bearing 60 is embedded in the seat plate 50, and the seat plate 50 can provide an installation space for the bearing 60. The motor shaft 331 passes through the hole of the bearing 60 to achieve positioning, so that the motor shaft 331 and the hole of the bearing 60 can be aligned.

[0084] According to some embodiments of the present invention, first through holes 12 are respectively provided on opposite sides of the casing 10, there are two seat plates 50 and two bearings 60, the two seat plates 50 and the two bearings 60 are respectively and correspondingly provided on opposite sides of the casing 10, the motor shaft 331 is selectively provided outside one side of the casing 10, and the motor shaft 331 passes through the corresponding first through holes 12 and bearings 60.

[0085] Specifically, the motor shaft 331 is selectively disposed outside one side of the housing 10, that is, according to actual use, the motor 33 can be disposed on the left side of the housing 10, and the motor 33 can be disposed on the right side of the housing 10. Therefore, the housing 10 is provided with first through holes 12 for the motor 33 to pass through, and correspondingly with seat plates 50 for mounting the bearing 60, so that the motor shaft 331 and the bearing 60 can be aligned.

[0086] According to some embodiments of the present invention, Figure 7 and Fig.10 As shown, the vertical air conditioner 100 further includes: a heat preservation seal 70 , which is selectively disposed on the other side of the casing 10 , and the heat preservation seal 70 seals the corresponding first through hole 12 and the bearing 60 .

[0087] The heat preservation seal 70 is used to seal the side of the housing 10 where the motor 33 is not installed. When the motor 33 is arranged on the left side of the housing 10, the heat preservation seal 70 is arranged on the right side of the housing 10. The seat plate 50 is fixedly connected to the housing 10 by two screws, which can be easily installed and removed. The heat preservation seal 70 is filled in the hole of the bearing 60. A horizontal handle is arranged on the outside of the heat preservation seal 70 for easy manual operation.

[0088] The heat-insulating seal 70 can be manually rotated to be squeezed in, or manually rotated to be taken out. The heat-insulating seal 70 has the advantages of quick and convenient installation, can achieve sealing and heat preservation, and can also prevent the outside air that has not passed through the heat exchanger 20 from directly flowing into the casing 10, thereby ensuring the heat exchange efficiency of the heat exchanger 20 in the vertical air conditioner 100.

[0089] According to some embodiments of the present invention, Figure 11-Figure 14 As shown, the fan assembly 30 also includes: a support frame 34, the support frame 34 is arranged on the opposite sides of the air duct member 31, the fan shaft 321 is rotatably arranged on the two support frames 34, and a second through hole 341 is arranged on the support frame 34. The motor shaft 331 passes through the second through hole 341 of the support frame 34 on one side and is transmission-connected with the fan shaft 321.

[0090] Among them, support frames 34 are arranged at both sides of the air duct member 31, and the structure of the support frame 34 is a cross frame. The support frame 34 is fixedly connected to the air inlet 311 of the air duct member 31, and the air inlet 311 is circular. The support frame 34 is locked and fixed at the four quadrant points of the circular air inlet 311 of the air duct member 31 by four screws, so that the support frame 34 and the air duct member 31 can be fixed more firmly.

[0091] According to some embodiments of the present invention, Fig.14 As shown, the support frame 34 includes: a shaft seat 342 and a plurality of legs 343, the shaft seat 342 is provided with a second through hole 341, the shaft seat 342 is also provided with a mounting groove 344 connected to the second through hole 341, the end of the fan shaft 321 is arranged in the mounting groove 344, the plurality of legs 343 are arranged at intervals around the outer periphery of the shaft seat 342, and the plurality of legs 343 are respectively fixedly connected to the side walls of the air duct member 31.

[0092] The plurality of legs 343 are arranged at intervals around the outer circumference of the shaft seat 342 , which can increase the stability of the connection between the plurality of legs 343 and the side wall of the air duct member 31 .

[0093] In addition, a second through hole 341 is provided at the center of the support frame 34, and the motor shaft 331 can pass through the second through hole 341. A mounting groove 344 connected to the second through hole 341 is also provided at the center of the support frame 34, and the mounting groove 344 is in the shape of a circular hole. The mounting groove 344 is connected and matched with the outer diameter of the fan shaft 321, and the mounting groove 344 can limit the position of the fan shaft 321, and can ensure that the fan shaft 321 is located at the center of the air duct member 31, so that the fan shaft 321 and the circular mounting groove 344 can be aligned.

[0094] When the motor 33 is installed on site later, there is no need to adjust the position of the fan 32, and only the motor 33 assembly needs to be installed, which has the advantage of quick and convenient installation.

[0095] Furthermore, the support frame 34 can connect the motor shaft 331 with the fan shaft 321 , and the motor shaft 331 can enter the shaft hole of the fan shaft 321 , thereby achieving the matching of the shaft holes of the motor shaft 331 and the fan shaft 321 .

[0096] At the same time, the motor shaft 331 is provided with a rotation-stopping surface, and the shaft hole of the fan shaft 321 is also provided with a rotation-stopping surface accordingly. The motor shaft 331 is connected and matched with the rotation-stopping surfaces of the shaft hole of the fan shaft 321, so that the motor shaft 331 and the fan shaft 321 can be matched more closely. When the motor 33 rotates, the motor shaft 331 drives the fan shaft 321 to rotate synchronously, so that the fan 32 can send air outward.

[0097] According to some embodiments of the present invention, Figure 1 As shown, the vertical air conditioner 100 further includes a protective cover 80 , which is disposed outside the casing 10 and covers the motor 33 .

[0098] The provision of the protective cover 80 can prevent the motor 33 from being hit by external objects.

[0099] In addition, the protective cover 80 can be fixedly connected to the housing 10 by screws, and the protective cover 80 is provided with a wire hole 91, so that the wires of the motor 33 can be passed through. The wires of the motor 33 extend to the outside through the wire hole 91, and the wires of the motor 33 can be connected to the control panel of the vertical air conditioner 100, so that the speed of the motor 33 can be easily controlled.

[0100] According to some embodiments of the present invention, Fig. 20 As shown, the vertical air conditioner 100 further includes: an electric heating element 90 , which is disposed in the chamber and located between the air supply port 312 and the air outlet 11 , and is used to heat the air flowing out of the air supply port 312 .

[0101] Specifically, the motor 33 of the vertical air conditioner 100 is arranged outside the housing 10, which can solve the problem of blockage of the air inlet 311 of the air duct member 31, and can also increase the air intake area of ​​the air inlet 311, thereby increasing the air output. When the air output increases, the electric heating wire can fully dissipate heat, thereby avoiding reddening and overheating.

[0102] In addition, the motor 33 itself will emit heat during operation. Since the motor 33 is arranged outside the casing 10, it does not pass through the cooling environment and does not form a cold and warm intersection. It can prevent the generation of condensation near the air duct member 31, thereby increasing the service life of the vertical air conditioner 100.
