Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples.
It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Fig. 1 is a schematic structural view illustrating an embodiment of an outdoor unit for an air conditioner according to the present invention. The outdoor unit 1 of the air conditioner may include a compressor 2 and a pipe, specifically, a suction pipe 3 and a discharge pipe 4 communicated with the compressor 2, and a refrigerant is sucked into the compressor 2 through the suction pipe 3 or discharged out of the compressor 2 through the discharge pipe 4. The outdoor unit 1 is provided with an air inlet and an air outlet, and the outdoor unit can also be provided with components such as a heat exchanger, an axial flow fan, an axial flow motor, a throttling device, a four-way valve and the like. The compressor 2 can be a fixed-frequency compressor, the power supply of the fixed-frequency compressor is directly provided by commercial power, the voltage is alternating current 220V, the frequency is 50Hz, the theoretical rotating speed is 3000r/min, and the actual rotating speed is 2800r/min due to resistance and the like during operation. More generally, the compressor 2 is a variable-frequency compressor, the power supply of which is provided by a variable-frequency module, the frequency of the analog three-phase alternating current output by the module can vary within 15-120Hz, and the voltage can vary between 30-200V. The speed of the compressor 2 can thus be varied within the range of 1500-9000 r/min. Taking the refrigeration mode as an example, when the rotating speed of the compressor 2 is increased, the refrigerating capacity is increased, the refrigerating effect is accelerated, and the room temperature is rapidly reduced in the refrigeration mode. When the temperature in the room is lowered to the vicinity of the set temperature, the rotational speed of the compressor 2 is lowered, the cooling capacity is lowered, and the room temperature is maintained. In designing the intake pipe 3 and the exhaust pipe 4 as the peripheral piping of the compressor 2, it is necessary to take into consideration various factors such as refrigerant resistance, noise, design of installing a temporary filter, a gas-liquid separator, a position of a nozzle, and a shape of a casing, and therefore, the design space of the intake pipe 3 and the exhaust pipe 4 is very small, and it is preferable that the bending is as small as possible. In the outdoor unit 1 of the air conditioner shown in fig. 1, the compressor 2 is disposed at the bottom of the outdoor unit, but is not limited thereto. It should be understood that the compressor 2 may be provided at other positions of the outdoor unit of the air conditioner by adjusting the suction pipe 3 and the discharge pipe 4 and the internal layout of the housing.
Specifically, as shown in fig. 2, a counterweight assembly 10 is disposed on the pipeline, and the natural frequency of the pipeline is changed by the counterweight assembly 10, so as to avoid the occurrence of operating noise or severe vibration caused by the superposition of the natural frequency of the pipeline and the operating frequency of the compressor. The weight assembly 10 shown in fig. 3 may be placed anywhere on a pipeline and is particularly suited for installation on a length of vertically oriented pipeline, such as the pipe section 31 shown in fig. 2. Such a tube section 31 has a continuous outer wall extending in the vertical direction. Therefore, the design space of the elbow pipe section 31 can be fully released, and meanwhile, the counterweight assembly 10 is more flexibly installed and is convenient for operation, replacement or maintenance of constructors. As shown in fig. 3, the weight assembly 10 mainly includes a weight block 11. The weight member 11 is made of a soft material having elasticity or a hard material. If hard material is used to make the weight block 11, a thicker soft material is wrapped outside the weight block to avoid scratching the pipeline. The soft material may be rubber or other composite material. The weight of the counter weight 11 can be obtained through software simulation according to the actual model of the compressor 2.
An elastic receiving portion 12 is formed in the weight 11. The elastic receiving portion 12 is recessed and formed integrally with the weight member 11. In the original state, the cross-sectional area of the elastic receiving portion 12 is smaller than the circular arc area of the corresponding position of the outer wall of the pipe. In use, the conduit passes through the resilient receptacle 12 and has a portion of its outer wall embedded in the resilient receptacle 12. After the assembly of the weight assembly 10 is completed, the elastic containing part 12 expands correspondingly to form a limit to the relative movement of the outer wall of the pipeline on one side of the outer wall of the pipeline.
The weight assembly 10 further includes a first fixing portion 13. The first fixing portion 13 is connected to the elastic accommodating portion 12. The first fixing portion 13 is disposed around a portion of the outer wall of the pipeline to form a first contact point 21 and a second contact point 22 on the outer wall of the pipeline. The positions of the first contact point 21 and the second contact point 22 have a height difference to create a self-locking between the weight assembly 10 and the pipeline.
Thus, through the counterweight assembly 10, even if the counterweight assembly is installed on the vertical pipe section 31, because the position between the first contact point 21 and the second contact point 22 has a height difference, self-locking between the counterweight assembly 10 and the pipeline can be formed under the self-gravity of the counterweight block 11, the counterweight block 11 cannot move downwards in the long-time use process, the pipeline and the running frequency of the compressor 2 cannot generate resonance, and the stability of the air conditioner is improved.
A preferred construction of the weight assembly 10 is further described with reference to fig. 3-5. As shown in fig. 3, the first fixing portion 13 has a spiral shape. The first fixing portion 13 is preferably made of a rigid material, such as a metal wire having a smooth surface and a suitable diameter. The first fixing portion 13 may be deformed to some extent on the basis of a certain external force applied by an operator, so as to install the weight assembly 10 outside the pipe. The first fixing portion 13 has a length of approximately 70% of the circumference of the outer wall of the pipe, and is bent in a spiral shape to entirely cover half of the circumference of the outer wall of the pipe. The first fixing portion 13 specifically includes a first end 14 and a second end 15 disposed higher than the first end 14. The first end 14 is disposed in the elastic receptacle 12. An opening is formed between the first end 14 and the second end 15, and the pipe enters the elastic container 12 from the opening formed between the first end 14 and the second end 15 and is fitted into the elastic container 12. When the pipe is inserted into the elastic receiving portion 12, the elastic receiving portion 12 is elastically deformed, and the restoring force of the elastic material acts on the first end 14 of the first fixing portion 13 to press the first end 14 toward the outer wall of the pipe to form the first contact point 21. On the other side, due to the penetration of the pipe, the first fixing portion 13 deforms itself so that the second end 15 is pressed against the outer wall of the pipe forming the second contact point 22. Thereby form the contact point respectively at the both ends of pipeline outer wall to under the effect of gravity, form the auto-lock, ensure that counter weight component 10 can not slide down when using.
In order to control the friction coefficient of the first contact point 21 and the second contact point 22, ensure the self-locking effect, and simultaneously play a role in protecting the outer wall of the pipeline, an elastic limiting part 16 is arranged in the elastic accommodating part 12. The first end 14 extends into the elastic limiting portion 16 to form a connection therebetween. The elastic receiving portion 12 elastically deforms to press the first end 14 toward the outer wall of the pipeline so that the elastic stopper portion 16 abuts against the outer wall of the pipeline to form a first contact point 21. At the other end, the first fixing portion 13 further includes an elastic protector 17 for the same purpose. The second end 15 is arranged in the elastic protection member 17, the first fixing portion 13 is deformed so that the second end 15 presses the outer wall of the pipeline, and the elastic protection member 17 abuts against the outer wall of the pipeline to form a second contact point 22. The elastic limiting portion 16 is preferably formed integrally with the elastic accommodating portion 12, and is fixed to a side wall of the elastic accommodating portion 12 contacting with an outer wall of the pipeline in a ring shape. The first end 14 is fixed to protrude from the elastic receiving portion 12. The elastic protector 17 is preferably an elastic sheath made of a soft material, and has a length of about one third of the total length of the first fixing portion 13. Preferably, the elastic protection member 17, the weight 11 and the elastic protection sleeve are made of the same material.
The self-locking effect is ensured by the relationship between the friction coefficient of the first contact point 21 and the second contact point 22, the height difference of the first contact point 21 and the second contact point 22 along the extension direction of the pipeline, and the distance between the center of gravity of the counterweight 11 and the center of the pipeline. Specifically, after selecting the materials of the elastic protection member 17, the weight 11 and the elastic protection sleeve, the friction coefficient of the soft material, i.e. the friction coefficient μ of the first contact point 21 and the second contact point 22, is determined by means of a look-up table. The distance x between the center of the weight 11 and the center line of the pipe is further determined. The height difference h of the first contact point 21 and the second contact point 22 in the direction of extension of the pipeline is determined by the friction coefficient mu and the distance x of the center of gravity of the counterweight 11 from the centerline of the pipeline. The three meet the following conditions: mu > h/2 x. Therefore, when assembling the counterweight assembly 10, the height difference between the first contact point 21 and the second contact point 22 along the pipeline extending direction can be adjusted according to the known friction coefficient and the distance between the gravity center of the counterweight 11 and the pipeline central line, so as to ensure the self-locking effect. Only one range of constraints need to be met due to the height difference, while the operational requirements are reduced. After the overall shape and weight of the balancing weight 11 are designed, the center of gravity of the balancing weight can be obtained through computer simulation.
In consideration of the possibility of collision against the packing box of the outdoor unit 1 during transportation and installation, it is preferable to further provide the second fixing portion 19. The second fixing portion 19 is provided around the outer wall of the pipe. An annular groove 18 is formed on the side of the weight member 11 away from the elastic receiving portion 12, and a second fixing portion 19 integrally limits the relative movement of the pipeline and the weight member 10 through the annular groove 18. The second fixing portion 19 is preferably provided below the first fixing portion 13, and is independent from and does not interfere with each other. The second fixing portion 19 is preferably a wire.
In another aspect, an air conditioner is also disclosed. The air conditioner includes a case 5 provided on an indoor side. The casing 5 is provided therein with a compressor 2 and an indoor-side heat exchanger 6. One indoor heat exchanger may be provided to exchange heat with only air. Two or more may be provided to exchange heat with air and other media, such as domestic water, etc. The casing 5 shown in fig. 7 is provided with only the indoor-side heat exchanger 6 that exchanges heat with air. The indoor heat exchanger 6 is disposed uppermost in the casing 5, and an indoor fan and a compressor 2 are sequentially disposed from top to bottom. In this structure, the structure at the position of the compressor 2 is more compact, and the piping design space is smaller. In order to achieve the damping effect, a weight assembly 10 is additionally provided to the suction pipe 3 or the discharge pipe 4 of the compressor 2.
Referring to fig. 3 to 5, in the air conditioner, the natural frequency of the pipeline is also changed by the weight assembly 10, so that the occurrence of operation noise or severe vibration caused by the superposition of the natural frequency of the pipeline and the operation frequency of the compressor 2 is avoided. The illustrated weight assembly 10 may be placed anywhere on a pipeline, and is particularly suited for installation on a vertical length of pipeline, such a pipe section 31 having a continuous outer wall extending in a vertical direction. Therefore, the design space of the elbow pipe section 31 can be fully released, and meanwhile, the counterweight assembly 10 is more flexibly installed and is convenient for operation, replacement or maintenance of constructors. As shown in fig. 3, the weight assembly 10 mainly includes a weight block 11. The weight member 11 is made of a soft material having elasticity or a hard material. If hard material is used to make the weight block 11, a thicker soft material is wrapped outside the weight block to avoid scratching the pipeline. The soft material may be rubber or other composite material. The weight of the balancing weight 11 can be obtained through software simulation according to the actual model of the compressor 2.
An elastic receiving portion 12 is formed in the weight 11. The elastic receiving portion 12 is recessed and formed integrally with the weight member 11. In the original state, the cross-sectional area of the elastic receiving portion 12 is smaller than the circular arc area of the corresponding position of the outer wall of the pipe. In use, the conduit passes through the resilient receptacle 12 and has a portion of its outer wall embedded in the resilient receptacle 12. After the assembly of the weight assembly 10 is completed, the elastic containing part 12 expands correspondingly to form a limit to the relative movement of the outer wall of the pipeline on one side of the outer wall of the pipeline.
The weight assembly 10 further includes a first fixing portion 13. The first fixing portion 13 is connected to the elastic accommodating portion 12. The first fixing portion 13 is disposed around a portion of the outer wall of the pipeline to form a first contact point 21 and a second contact point 22 on the outer wall of the pipeline. The positions of the first contact point 21 and the second contact point 22 have a height difference to create a self-locking between the weight assembly 10 and the pipeline.
Through the counter weight component 10, even install on vertical pipe section 31, because the position between first contact point 21 and the second contact point 22 has the difference in height, can form the auto-lock between counter weight component 10 and the pipeline under the self gravity of balancing weight 11, in long-time use, balancing weight 11 can not the lapse, ensures that pipeline and compressor 2 operating frequency can not produce resonance, improves the stability of air conditioner.
The first fixing portion 13 is formed in a spiral shape. The first fixing portion 13 is preferably made of a rigid material, such as a metal wire having a smooth surface and a suitable diameter. The first fixing portion 13 may be deformed to some extent on the basis of a certain external force applied by an operator, so as to install the weight assembly 10 outside the pipe. The first fixing portion 13 has a length of approximately 70% of the circumference of the outer wall of the pipe, and is bent in a spiral shape to entirely cover half of the circumference of the outer wall of the pipe. The first fixing portion 13 specifically includes a first end 14 and a second end 15 disposed higher than the first end 14. The first end 14 is disposed in the elastic receptacle 12. An opening is formed between the first end 14 and the second end 15, and the pipe enters the elastic container 12 from the opening formed between the first end 14 and the second end 15 and is fitted into the elastic container 12. When the pipe is inserted into the elastic receiving portion 12, the elastic receiving portion 12 is elastically deformed, and the restoring force of the elastic material acts on the first end 14 of the first fixing portion 13 to press the first end 14 toward the outer wall of the pipe to form the first contact point 21. On the other side, due to the penetration of the pipe, the first fixing portion 13 deforms itself so that the second end 15 is pressed against the outer wall of the pipe forming the second contact point 22. Thereby form the contact point respectively at the both ends of pipeline outer wall to under the effect of gravity, form the auto-lock, ensure that counter weight component 10 can not slide down when using. In order to protect the pipeline, the outer side of the first fixing portion 13 may be covered with a soft material, so that the first fixing portion 13 and the weight block 11 are integrally formed.
The self-locking effect is ensured by the relationship between the friction coefficient of the first contact point 21 and the second contact point 22, the height difference of the first contact point 21 and the second contact point 22 along the extension direction of the pipeline, and the distance between the center of gravity of the counterweight 11 and the center of the pipeline. Specifically, after selecting the materials of the elastic protection member 17, the weight 11 and the elastic protection sleeve, the friction coefficient of the soft material, i.e. the friction coefficient μ of the first contact point 21 and the second contact point 22, is determined by means of a look-up table. The distance x between the center of the weight 11 and the center line of the pipe is further determined. The height difference h of the first contact point 21 and the second contact point 22 in the direction of extension of the pipeline is determined by the friction coefficient mu and the distance x of the center of gravity of the counterweight 11 from the centerline of the pipeline. The three meet the following conditions: mu > h/2 x. Therefore, when assembling the counterweight assembly 10, the height difference between the first contact point 21 and the second contact point 22 along the extension direction of the pipeline can be adjusted according to the known friction coefficient and the distance between the center of the counterweight 11 and the central line of the pipeline, so as to ensure the self-locking effect. Only one range of constraints need to be met due to the height difference, while the operational requirements are reduced. After the overall shape and weight of the balancing weight 11 are designed, the center of gravity of the balancing weight can be obtained through computer simulation.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
