Description

Technical Field

[0001] The present invention belongs to the field of heat pumps, specifically, an air-source heat pump. This air-source heat pump utilizes an all-in-one structure, with the condenser positioned at the bottom of the unit, which improves overall stability and enhances wall-mounted stability. Furthermore, the unit includes a protective plate that protects the condenser and is assembled with the fan frame, further enhancing structural stability while also reducing noise and vibration. Background Art

[0002] With the development of heat pump applications, heat pump product designs have also diversified. Larger side-discharge air-source heat pump chillers were initially designed as modular units, typically with top-discharge. Side-discharge air-source heat pump chillers, on the other hand, have typically been concentrated in smaller models, but are currently trending towards larger units.

[0003] Due to the current structural limitations of the air source heat pump chiller with a side-outlet design, the air source heat pump chiller with a smaller power output generally adds a condenser (water side) to the top of the existing air conditioner. However, such a design will cause the center of gravity of the entire machine to be too high, resulting in insufficient stability of the center of gravity of the product. In another solution of the prior art, the space in the compressor compartment of the machine body is larger, so the condenser (water side) is placed in the compressor compartment, but there is also a technical problem that the center of gravity is biased towards the compressor side, resulting in structural instability. In addition, the use of this solution will result in limited selection of condensers, and only shell and tube heat exchangers or plate heat exchangers can be selected. Shell and tube heat exchangers generally have better heating effects, but there is a large gap in cooling effects. Although plate heat exchangers have better heat exchange, they are less adaptable to complex water quality and require higher installation conditions and higher subsequent maintenance costs.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of existing technologies by providing an air-source heat pump with a condenser positioned at the bottom of the heat pump body. By adjusting the structural space within the heat pump body, the condenser can be inserted through the fan and compressor compartments, effectively utilizing the internal storage space. Furthermore, the heat pump body incorporates a protective plate structure for the condenser. A mounting mechanism connects a portion of the fan frame to the protective plate, stabilizing the overall structure while also providing vibration and noise reduction.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] The present invention provides an air source heat pump, comprising:

[0008] The shell is provided with a middle partition for dividing the internal accommodation space;

[0009] The fan is installed on the fan frame on one side of the middle partition;

[0010] The evaporator is arranged along the side wall and the rear wall of the shell and is on the same side of the middle partition as the fan;

[0011] The compressor and electronic control components are located on the other side of the middle partition opposite to the fan;

[0012] The air source heat pump further comprises a condenser covering the inner bottom of the shell and passing through the middle partition. The condenser is provided with a guard plate abutting against the middle partition.

[0013] In the above solution, the condenser (water side) in the heat pump is arranged at the bottom of the body, which can lower the center of gravity of the whole machine and stabilize the overall structure. Compared with the solution in which the condenser is only arranged at the bottom of the fan compartment or the bottom of the compressor compartment, which causes the center of gravity to shift, the condenser provided by the present invention passes through the middle partition and completely occupies the bottom space of the body, further increasing its stability. In addition, this design method also avoids the existing method of placing the condenser at the top of the body, which causes the defrost water (or rainwater) to pass through the lower compressor and electrical structure when draining, reducing the waterproof and water-conducting requirements of the internal components of the body. Furthermore, in order to prevent the insulation layer on the surface of the condenser tube from falling off during long-term use, thereby affecting the safe operation of the fan, the present invention provides a protective plate covering the condenser. The protective plate is offset against the middle partition to achieve a relatively simple connection.

[0014] In the above solution, the compressor is positioned above the condenser. A support plate is installed at the bottom of the compressor, overlapping the center partition and the side wall of the housing. This supports the compressor's weight while reducing the impact of compressor vibration on the condenser. The electronic control components are located above the compressor, near the top of the housing. Their heat dissipation structure extends through the center partition toward the fan compartment, enhancing heat dissipation. Furthermore, an air vent is provided on the front wall of the housing, corresponding to the location of the fan.

[0015] A further solution of the present invention is that the fan frame is mounted on the top of the guard plate, or the fan frame is mounted on the top of the condenser.

[0016] In the above scheme, since the present invention occupies the bottom space of the machine body with the condenser, the fan rack cannot be connected directly to the chassis of the machine body in the same way as in the prior art. In this regard, the present invention, from the perspective of space utilization and installation firmness, can directly assemble the fan rack with the condenser, or install the fan rack on the guard plate. When adopting the above different schemes, it is necessary to make corresponding adjustments to the assembly structure of the fan rack according to different needs. For example, screw holes are provided on the side surface of the bottom of the fan rack, which are installed corresponding to the screw holes of the plates vertically provided on the upper surface of the condenser, so as to realize the direct connection between the fan rack and the condenser; for another example, screw holes are provided on the bottom plane of the fan rack, which are connected corresponding to the screw holes on the horizontal surface of the top of the guard plate.

[0017] A further solution of the present invention is that at least one side of the bottom of the fan frame is provided with a flange extending in the horizontal direction, and the flange abuts against the guard plate after the fan frame is assembled; preferably, the flange is provided with screw holes for assembling the air supply frame and the guard plate or condenser.

[0018] In the above solution, since the fan frame is vertically installed within the machine body along the height of the evaporator, its height is relatively high, and multiple fans may be installed and operating simultaneously, so its stability needs to be further enhanced. The present invention provides a horizontally bent flange structure at the bottom edge of the fan frame. This flange structure abuts against the top surface of the guard plate or the top surface of the condenser, increasing the contact area between the fan frame and the guard plate or condenser, thereby improving stability. The flange can also be provided with screw holes, which enable stable installation of the fan frame and the guard plate or condenser. The fan frame, abutting the guard plate, can use its own weight to press and secure the guard plate.

[0019] A further solution of the present invention is that the upper surface of the guard plate is made of elastic material so that the flange of the wind turbine frame and the guard plate are interference-fitted after assembly.

[0020] In the above scheme, the surface of the guard plate can be adhered or coated with a functional material layer. When a material with a certain elasticity is selected to cover the upper surface of the guard plate, the flange at the bottom of the fan frame can form an interference fit with the surface of the guard plate. On the one hand, the firmness of the assembly can be increased. On the other hand, the elastic material layer can absorb the vibration generated when the fan is running, thereby playing a role in shock absorption and noise reduction.

[0021] A further solution of the present invention is: it also includes a support assembled with the bottom of the fan frame, the support is installed on the top of the guard plate, or is located on the top of the condenser and passes through the guard plate; preferably, the support is integrally formed with the top of the condenser.

[0022] In the above solution, when multiple fans are installed on a fan rack, or the fan housing is relatively tall, a support structure can be added to the guard plate or condenser to increase the load-bearing capacity of the fan rack. The support not only increases the mounting stability of the fan rack, but also reduces the stress generated by the fans during operation, thereby extending the service life of the guard plate and protecting the structural stability of the condenser.

[0023] A further solution of the present invention is that: at least two opposite sides of the support are provided with bayonet holes, and the bottom of the fan rack is provided with claws corresponding to the bayonet holes; the support and the bottom of the fan rack are also provided with corresponding screw holes respectively.

[0024] In the above solution, after long-term use of the heat pump, the vibration generated by the fan will weaken the firmness of the screw connection, causing the overall structure of the fan frame to loosen. However, the support used in the present invention not only uses screw holes to achieve connection with the fan frame, but also includes a bayonet corresponding to the claw at the bottom of the fan frame. After the screws are loosened, the overall assembly structure can still maintain the installation firmness and will not loosen.

[0025] A further solution of the present invention is that one end of the guard plate along the length direction of the condenser abuts against the bottom of the middle partition, so that the guard plate is arranged in contact with the upper surface of the condenser; preferably, the guard plate passes through the middle partition and completely covers the condenser.

[0026] In the above solution, the bottom of the middle partition is provided with an opening for the condenser to pass through. The edge of the opening is provided with a mounting flange that abuts the upper surface of the guard plate. The mounting flange is also provided with screw holes to achieve a fixed connection with the guard plate. The lower surface of the guard plate fits the shell and tube structure of the condenser, making the overall structure more compact and secure.

[0027] A further solution of the present invention is that a plurality of elastic fixing clips for carrying the condenser pipelines are provided at the bottom of the guard plate, and the elastic fixing clips are engaged with the clip holes on the guard plate corresponding to the positions of the condenser pipelines.

[0028] In the above solution, the locking holes are two opposing stepped holes, with the hole opening on the closer side larger than the farther side. The elastic fixing clip is U-shaped, with two clips at the top of the U extending into the larger portion of the hole. The clips are then snapped into the farther sides of the holes using their own elasticity, achieving a snap connection. The U-shaped bottom of the elastic fixing clip scoops up the condenser pipe, thereby supporting its weight.

[0029] A further solution of the present invention is that the guard plate is formed by bending a single plate multiple times, and a plurality of gaskets are provided on the lower surface thereof to abut against the smooth part of the condenser.

[0030] In the above scheme, due to the presence of a smooth tube structure on the upper surface of the shell and tube condenser, there are still some gaps between it and the lower surface of the guard plate formed by the bending of the plate. In order to reduce the decrease in structural stability caused by the gap, a gasket is arranged on the lower surface of the guard plate to fill the gap, thereby making the structure more compact and firm.

[0031] A further embodiment of the present invention provides a plurality of bosses for mounting the power supply motor on the fan frame. These bosses protrude from the fan frame surface and are provided with inwardly recessed reinforcing ribs, the recessed ribs being oriented in the opposite direction to the protruding bosses. The bosses and inwardly recessed ribs work together to ensure that the structural strength of the fan motor portion meets standard requirements.

[0032] A further solution of the present invention is that the condenser is a shell and tube condenser, and its water outlet and water inlet are both arranged on the compressor side of the shell accommodating space.

[0033] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0034] 1. The air-source heat pump provided by the present invention locates the condenser (water side) at the bottom of the machine body, which lowers the center of gravity of the entire machine and stabilizes the overall structure. Compared with solutions that only locate the condenser at the bottom of the fan compartment or the bottom of the compressor compartment, which results in a shift in the center of gravity, the condenser provided by the present invention penetrates the middle partition and completely occupies the space at the bottom of the machine body, further increasing its stability. In addition, this design avoids the existing practice of locating the condenser at the top of the machine body, which requires defrost water (or rainwater) to drain through the lower compressor and electrical structure, thus reducing the need for waterproofing and water diversion of internal components.

[0035] 2. In the air source heat pump provided by the present invention, a horizontally bent flange structure is provided at the bottom edge of the fan frame. The flange structure abuts against the top surface of the guard plate or the top surface of the condenser, thereby increasing the contact area between the fan frame and the guard plate or condenser, thereby improving stability.

[0036] 3. In the air source heat pump provided by the present invention, the surface of the guard plate can be adhered or coated with an elastic material layer, so that the flange at the bottom of the fan frame forms an interference fit with the surface of the guard plate. On the one hand, this can increase the firmness of the assembly, and on the other hand, the elastic material layer can absorb the vibration generated by the operation of the fan, thereby playing a role in vibration reduction and noise reduction.

[0037] 4. In the air source heat pump provided by the present invention, a support structure connected to the fan frame can be added to the guard plate or condenser. The support structure not only increases the installation strength of the fan frame, but also reduces the stress generated by the fan during operation, thereby extending the service life of the guard plate and protecting the structural stability of the condenser.

[0038] 5. In the air source heat pump provided by the present invention, the fan frame and the support are connected not only by screws, but also by a clamping connection between a claw provided at the bottom of the fan frame and a clamping slot on the support, thereby preventing the screws from loosening due to long-term vibration and causing a decrease in the stability of the assembly structure.

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

Therefore, they cannot be understood as limiting the present invention.

[0052] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0053] like Figures 1 to 7 As shown, the present invention provides an air-source heat pump with a condenser located at the bottom of the heat pump body. By adjusting the structural space within the heat pump body, the condenser can be inserted through the fan and compressor compartments, effectively utilizing the internal storage space. Furthermore, the heat pump body is equipped with a protective plate structure for the condenser. A mounting mechanism is installed between a portion of the fan frame and the protective plate, stabilizing the overall structure while also providing vibration and noise reduction.

[0054] The heat pump includes components such as a shell 9, a fan 6, an evaporator 7, a compressor 5 and an electronic control element 8. The accommodating space in the shell 9 is divided into a fan compartment and a compressor compartment by a middle partition 4. The fan compartment includes a fan 6, a fan frame 2 and an evaporator 7 partially arranged around the fan. The compressor compartment includes a compressor 5 arranged at the bottom and an electronic control element 8 arranged at the top.

[0055] The air source heat pump further includes a condenser 10 covering the inner bottom of the shell 9 and passing through the middle partition 4 . The condenser 10 is provided with a guard plate 1 that abuts against the middle partition 4 .

[0056] The compressor 5 is positioned above the condenser 10. A support plate 51 is located at the bottom of the compressor 5, overlapping the center partition 4 and the side wall of the housing 9. This supports the weight of the compressor 5 while also reducing the impact of compressor 5 vibration on the condenser 10. The electronic control element 8 is located above the compressor 5, near the top of the housing. Its heat dissipation structure extends through the center partition 4 toward the fan compartment, enhancing heat dissipation. Furthermore, an air vent is provided on the front wall of the housing 9, corresponding to the location of the fan.

[0057] Example 1

[0058] In this embodiment, Figure 1 As shown, an air source heat pump is provided, comprising:

[0059] The housing 9 is provided with a partition 4 for dividing the internal accommodation space;

[0060] The fan 6 is provided on the fan frame 2 on one side of the middle partition 4;

[0061] The evaporator 7 is arranged along the side wall and the rear wall of the housing 9 and is located on the same side of the middle partition 4 as the fan 6;

[0062] The compressor 5 and the electronic control element 8 are both arranged on the other side of the middle partition 4 opposite to the fan 6;

[0063] The air source heat pump further includes a condenser 10 covering the inner bottom of the shell 9 and passing through the middle partition 4 . The condenser 10 is provided with a guard plate 1 that abuts against the middle partition 4 .

[0064] In this embodiment, the condenser (water side) in the heat pump is arranged at the bottom of the body, which can lower the center of gravity of the whole machine and stabilize the overall structure. Compared with the solution of arranging the condenser only at the bottom of the fan compartment or the bottom of the compressor compartment, which causes the center of gravity to shift, the condenser provided by this embodiment passes through the middle partition and completely occupies the bottom space of the body, further increasing its stability. In addition, this design method also avoids the existing method of arranging the condenser at the top of the body, which causes the defrost water (or rainwater) to pass through the lower compressor and electrical structure when draining, reducing the waterproof and water-conducting requirements of the internal components of the body. Furthermore, in order to prevent the insulation layer on the surface of the condenser tube from falling off during long-term use, thereby affecting the safe operation of the fan, this embodiment provides a protective plate covering the condenser. The protective plate is offset against the middle partition to achieve a relatively simple connection.

[0065] In this embodiment, the compressor 5 is positioned above a portion of the condenser 10. A support plate 51 is provided at the bottom of the compressor 5, overlapping the intermediate partition 4 and the sidewalls of the housing 9. This supports the weight of the compressor 5 while also reducing the impact of compressor 5 vibration on the condenser 10. The electronic control element 8 is located above the compressor 5, near the top of the housing. Its heat dissipation structure extends through the intermediate partition 4 toward the fan compartment, enhancing heat dissipation. Furthermore, an air vent is provided on the front wall of the housing 9, corresponding to the location of the fan.

[0066] In this embodiment, the fan frame 2 is assembled on the top of the guard plate 1 .

[0067] In this embodiment, because condenser 10 occupies the bottom space of the machine body, the fan frame cannot be directly connected to the chassis of the machine body, as in the prior art. To address this issue, this embodiment, considering space utilization and secure installation, mounts fan frame 2 on the guard plate 1. Specifically, screw holes can be provided on the bottom plane of fan frame 2 to align with corresponding screw holes on the top horizontal surface of guard plate 1.

[0068] In this embodiment, Figure 4 As shown, at least one side of the bottom of the fan rack 2 is provided with a flange 21 extending in the horizontal direction, and the flange 21 abuts against the guard plate 1 after the fan rack 2 is assembled; preferably, the flange is provided with screw holes for assembling the air supply rack and the guard plate or condenser.

[0069] In this embodiment, since the fan frame 2 is vertically arranged within the machine body along the height of the evaporator 7, its height is relatively high, and there may be multiple fans 6 operating simultaneously, its stability needs to be further enhanced. In this embodiment, a flange structure that bends horizontally is provided at the bottom edge of the fan frame 2. The flange structure abuts against the top surface of the guard plate 1 or the top surface of the condenser 10, which can increase the contact area between the fan frame 2 and the guard plate 1 or condenser 10, thereby improving stability. Screw holes can also be provided on the flange 21, through which the fan frame and the guard plate or condenser can be stably installed. The fan frame 2 abutting against the guard plate 1 can use its own weight to press and fix the guard plate 1.

[0070] In this embodiment, the upper surface of the guard plate 1 is made of elastic material, so that the flange 21 of the wind frame 2 and the guard plate 1 are interference-fitted after assembly.

[0071] In this embodiment, the surface of the guard plate 1 can be adhered or coated with a functional material layer. When a material with a certain elasticity is selected to cover the upper surface of the guard plate 1, the flange 21 at the bottom of the fan frame 2 can form an interference fit with the surface of the guard plate 1. On the one hand, the firmness of the assembly can be increased. On the other hand, the elastic material layer can absorb the vibration generated when the fan is running, thereby playing a role in shock absorption and noise reduction.

[0072] In this embodiment, the condenser 10 is a shell and tube condenser, and its water outlet and water inlet are both arranged on one side of the compressor 5 in the housing space of the shell 9.

[0073] Example 2

[0074] The difference between this embodiment and embodiment 1 is that:

[0075] In this embodiment, the fan frame 2 is assembled on the top of the condenser 10 .

[0076] In this embodiment, because condenser 10 occupies the bottom space of the machine body, the fan frame cannot be directly connected to the chassis of the machine body as in the prior art. Therefore, to optimize space utilization and ensure secure installation, fan frame 2 is mounted on condenser 10. Specifically, screw holes are provided on the bottom side of fan frame 2 to correspond with the screw holes on the vertical plates on the upper surface of condenser 10.

[0077] Other implementations of this embodiment are the same as those of Example 1.

[0078] Example 3

[0079] This embodiment is a further improvement of the air source heat pump based on the first embodiment, specifically including:

[0080] In this embodiment, Figure 2 As shown, the heat pump further includes a support 3 assembled with the bottom of the fan frame 2 , and the support 3 is installed on the top of the guard plate 1 .

[0081] In this embodiment, when multiple fans 6 are installed on fan rack 2 or the housing is relatively high, a support structure can be added to guard plate 1 to increase the load-bearing capacity of the fan rack. The support 3 not only increases the mounting stability of fan rack 2, but also reduces the stress generated by fans 6 during operation, thereby extending the service life of guard plate 1.

[0082] In this embodiment, Figure 4 As shown, at least two opposite sides of the support 3 are provided with bayonet holes 31, and the bottom of the fan frame 2 is provided with claws 22 corresponding to the bayonet holes 31; the bottoms of the support 3 and the fan frame 2 are also provided with corresponding screw holes.

[0083] In this embodiment, after long-term use of the heat pump, the vibration generated by the fan 6 will weaken the firmness of the screw connection, causing the overall structure of the fan frame 2 to loosen. However, the support 3 used in this embodiment not only uses screw holes to achieve connection with the fan frame 2, but also includes a bayonet 31 corresponding to the claw 22 at the bottom of the fan frame 2. After the screws are loosened, the overall assembly structure can still maintain the installation firmness and will not loosen.

[0084] In this embodiment, one end of the guard plate 1 along the length direction of the condenser 10 abuts against the bottom of the middle partition 4, so that the guard plate 1 is arranged in contact with the upper surface of the condenser 10; preferably, the guard plate passes through the middle partition 4 and completely covers the condenser.

[0085] In this embodiment, Figure 2 As shown, the bottom of the middle partition 4 is provided with an opening for the condenser 10 to pass through, and the edge of the opening is provided with a mounting flange 41, which abuts against the upper surface of the guard plate 1. At the same time, the mounting flange 41 is provided with a screw hole to achieve a fixed connection with the guard plate 1. The lower surface of the guard plate 1 fits the shell and tube structure of the condenser 10, making the overall structure more compact and firm.

[0086] In this embodiment, Figure 2 and Figure 3 As shown, a plurality of elastic fixing clips 12 for supporting the pipelines of the condenser 10 are provided at the bottom of the protective plate 1 , and the elastic fixing clips 12 are engaged with the clip holes 11 on the protective plate 1 corresponding to the positions of the pipelines of the condenser 10 .

[0087] In this embodiment, Figure 5 As shown, the locking holes 11 are two opposed stepped holes, with the hole opening on the closer side larger than the farther side. The elastic fixing clip 12 is U-shaped, with two clips at the top of the U extending into the larger portion of the locking hole 11. The clips are clamped into the farther sides of the two locking holes 11 by their own elasticity, achieving a locking connection. The U-shaped bottom of the elastic fixing clip 12 scoops over the condenser 10 pipes, thereby bearing their weight.

[0088] In this embodiment, Figure 6 As shown, the guard plate 1 is formed by bending a single plate multiple times, and a plurality of gaskets 13 are provided on the lower surface thereof to abut against the smooth part of the condenser 10 .

[0089] In this embodiment, due to the presence of a smooth tube structure on the upper surface of the shell and tube condenser, there are still some gaps between it and the lower surface of the guard plate 1 formed by the bending of the plate. In order to reduce the decrease in structural stability caused by the gap, a gasket 13 is provided on the lower surface of the guard plate 1 to fill the gap, thereby making the structure more compact and firm.

[0090] Example 4

[0091] The difference between this embodiment and embodiment 3 is that:

[0092] In this embodiment, Figure 3 As shown, the heat pump further includes a support 3 assembled with the bottom of the fan frame 2, the support 3 is mounted on the top of the condenser 10 and passes through the guard plate 1; preferably, the support is integrally formed with the top of the condenser.

[0093] In this embodiment, when multiple fans 6 are installed on the fan rack 2 or the housing is relatively high, a support structure can be added to the condenser 10 to increase the load-bearing capacity of the fan rack. The support 3 not only increases the installation security of the fan rack 2, but also reduces the stress generated by the fans 6 during operation, thereby protecting the structural stability of the condenser 10.

[0094] Other implementations of this embodiment are the same as those of Example 3.

[0095] Example 5

[0096] This embodiment is a further improvement of the air source heat pump based on embodiment 1, 2, 3 or 4, specifically including:

[0097] In this embodiment, Figure 7 As shown, the fan frame 2 is equipped with several bosses 23 for mounting the power supply motor. These bosses 23 protrude from the fan frame surface and are equipped with inwardly recessed reinforcing ribs 24. The recessed direction of the ribs is opposite to the protrusion direction of the bosses. These bosses 23 and the inwardly recessed reinforcing ribs 24 work together to ensure that the structural strength of the fan frame 2 housing the fan motor meets standard requirements.

[0098] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
