Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and particularly provides a fixing structure for an air conditioner compressor air delivery pipeline and an air conditioner. Background Art

[0002] In recent years, with the continuous improvement of people's living standards and the continuous increase of living space, central air conditioners have gradually begun to be installed in different regional locations. Therefore, higher requirements are put forward for the applicability and reliability of air conditioner products. For the high-capacity output of the outdoor unit, there must be a high-capacity output of the compressor. Therefore, a compressor with gas injection and enthalpy increase is designed to enhance the capacity output of the compressor. However, the air delivery pipeline corresponding to the compressor body is relatively slender, and the compressor is the largest power vibration source of the entire outdoor unit. Therefore, there is a risk of rupture of the compressor body air delivery pipeline during the long-term operation of the outdoor unit, which will cause the outdoor unit to stop running normally, seriously affecting the product quality.

[0003] To solve the above problems, an integrated fixing member is usually provided on the existing compressor air delivery pipeline. The integrated fixing member is sleeved outside the air delivery pipeline to fix the air delivery pipeline and absorb the vibration on the air delivery pipeline at the same time. However, since the operating frequency of the compressor changes within a specific range, when the operating frequency of the compressor is consistent with the natural frequencies of the integrated fixing member and the air delivery pipeline, the integrated fixing member and the air delivery pipeline will have large-amplitude fluctuations. Therefore, how to avoid large-amplitude fluctuations of the fixing member and the air delivery pipeline has become a technical problem to be solved urgently in this field.

[0004] In view of this, a new fixing structure for an air conditioner compressor air delivery pipeline and an air conditioner are needed in this field to solve the existing problems. Summary of the Utility Model

Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios.

[0025] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "install", "connect", "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0026] First, the existing air conditioner compressors are described. The existing compressor's gas delivery pipeline is usually relatively slender. Since the compressor is the main vibration source of the air conditioner, when the air conditioner operates for a long time, if the gas delivery pipeline is not well fixed, the gas delivery pipeline will vibrate driven by the compressor, posing a risk of pipeline breakage. To solve the above problems, an integrated fixing member is usually provided on the existing compressor gas delivery pipeline. The integrated fixing member is sleeved outside the gas delivery pipeline to fix the gas delivery pipeline and absorb the vibration on the gas delivery pipeline. However, since the operating frequency of the compressor varies within a specific range, when the operating frequency of the compressor is the same as the natural frequencies of the integrated fixing member and the gas delivery pipeline, the integrated fixing member and the gas delivery pipeline will experience large-amplitude fluctuations. Therefore, how to avoid large-amplitude fluctuations of the fixing member and the gas delivery pipeline has become a technical problem urgently to be solved in this field. For this reason, the following embodiments are proposed.

[0027] Embodiment 1:

[0028] As Figures 1 - 3 shown, to solve the problem that the compressor of the existing air conditioner will resonate with the gas delivery pipeline and the fixing member during the frequency conversion process, causing large-amplitude fluctuations of the gas delivery pipeline and the fixing member, the fixing structure 1 of the air conditioner compressor gas delivery pipeline of the present utility model includes a body 11. The body 11 includes a detachable first part 111 and a second part 112. The first part 111 and / or the second part 112 are used to fix the gas delivery pipeline and form a combined body with the gas delivery pipeline. The first part 111 and the second part 112 can be separated or combined to change the size of the combined body. The fixing structure 1 further includes a driving device 12. The driving device 12 is drivingly connected to the first part 111 and / or the second part 112 to drive the first part 111 and the second part 112 to combine or separate. The driving device 12 is a coil 121 and a magnet 122. The magnet 122 is provided on the first part 111, and the coil 121 is provided on the second part 112. When the coil 121 is energized in the first direction, the magnetic field generated by the coil 121 can attract the magnet 122. When the coil 121 is energized in the second direction, the magnetic field generated by the coil 121 repels the magnet 122.

[0029] In the case of adopting the above-mentioned implementation manner, during the operation of the air conditioner compressor of the present utility model, as the operating frequency of the compressor changes, when the operating frequency of the compressor is consistent with the natural frequency of the combination formed by the main body 11 of the fixed structure 1 and the air duct, in order to avoid resonance between the compressor and the combination, the first part 111 and the second part 112 of the main body 11 can be separated or combined by energizing the coil 121 on the second part 112 in different directions (the change is based on the initial state of the first part 111 and the second part 112). After the first part 111 and the second part 112 are separated or combined, since the size of the combination changes, the natural frequency of the combination itself will also change accordingly. Specifically, when the operating frequency of the compressor is consistent with the natural frequency of the combination, the coil 121 can be energized in the first direction, so that the magnetic field generated by the coil 121 attracts the magnet 122, thereby combining the first part 111 and the second part 112, and further reducing the natural frequency of the combination. Or the coil 121 can be energized in the second direction, so that the magnetic field generated by the coil 121 repels the magnet 122, thereby separating the first part 111 and the second part 112, and further increasing the natural frequency of the combination. Through the above two methods, the natural frequency of the combination can be staggered from the operating frequency of the compressor, avoiding resonance, and solving the problem that the compressor of the existing air conditioner generates resonance with the air duct and the fixing parts during the frequency conversion process, causing large fluctuations in the air duct and the fixing parts.

[0030] In a possible implementation manner, the driving device 12 is a coil 121 and a magnet 122. A magnet 122 is provided on the first part 111, and a coil 121 is provided on the corresponding second part 112. The first part 111 and the second part 112 can be combined when the coil 121 is energized. The fixed structure 1 further includes a reset device (not shown in the figure). The reset device can be a reset spring. The two ends of the reset spring are respectively connected to the first part 111 and the second part 112. The first part 111 and the second part 112 can be separated under the action of the reset spring when the coil 121 is de-energized.

[0031] In the case of adopting the above-mentioned implementation manner, different from the previous implementation manner, in this implementation manner, the magnetic field direction of the coil 121 is not controlled by the method of positive and negative power supply, and then the combination and separation of the first part 111 and the second part 112 are controlled. Instead, only the attraction between the energized coil 121 and the magnet 122 is used to overcome the elastic force of the reset spring to combine the first part 111 and the second part 112, and the first part 111 and the second part 112 are separated by the elastic force of the reset spring after the coil 121 is de-energized. Compared with the previous implementation manner, in this implementation manner, there is no need to set up equipment for positive and negative power supply to the coil 121, and only a simple reset spring needs to be set to meet the requirements, reducing the equipment cost.

[0032] Example Two

[0033] The foregoing embodiments expounded on the problems existing in the compressor, gas pipeline, and fixing structure 1 in terms of principle. Next, a description will be given in combination with specific circumstances. As Figures 1 - 3 shown, in this embodiment, the gas pipeline includes an intake pipe, a return pipe, and an exhaust pipe. Correspondingly, the main body 11 includes a detachable first part 111, a second part 112, and a third part 113. The first part 111, the second part 112, and the third part 113 respectively fix the intake pipe, the return pipe, and the exhaust pipe. The first end of the second part 112 is detachably connected to the first part 111, and the second end of the second part 112 is detachably connected to the third part 113. A magnet 122 is provided on the first part 111. Correspondingly, a coil 121 is provided at the first end of the second part 112, and a magnet 122 is provided at the second end of the second part 112. Correspondingly, a coil 121 is provided on the third part 113. Mounting grooves 114 for placing the magnet 122 or the coil 121 are provided on the first part 111, the second part 112, and the third part 113. A winding post 115 is provided in the mounting groove 114 for placing the coil 121. Fixing holes 116 for fixing the intake pipe, the return pipe, and the exhaust pipe are respectively provided on the first part 111, the second part 112, and the third part 113. The fixing holes 116 are connected to channels 117 for the intake pipe, the return pipe, and the exhaust pipe to enter. A fillet 118 is provided at the inlet of the channel 117, and the side wall of the channel 117 is provided as a guiding bevel 119.

[0034] In the case of adopting the above embodiment, first, the magnet 122 and the coil 121 are placed in the mounting grooves 114 on the first part 111, the second part 112, and the third part 113, and the coil 121 is wound around the winding post 115 in the mounting groove 114 for fixation. Then, the intake pipe, the return pipe, and the exhaust pipe are respectively fixed in the fixing holes 116 through the channels 117 on the first part 111, the second part 112, and the third part 113. Then, according to the vibration conditions of the intake pipe, the return pipe, and the exhaust pipe, the first part 111, the second part 112, and the third part 113 are selectively combined or separated by energizing the coil 121 in the forward and reverse directions, thereby avoiding resonance.

[0035] The advantages of the above setting method are as follows: through the above embodiments, the first part 111 and the second part 112, the second part 112 and the third part 113, or the first part 111, the second part 112 and the third part 113 can be selectively split or combined, which is more flexible and convenient to operate. On the other hand, by setting rounded corners 118 at the inlets of the channels 117 on the first part 111, the second part 112 and the third part 113 and setting the side walls of the channels 117 as guiding bevels 119, it is convenient to install the intake pipe, the return air pipe and the exhaust pipe into the fixing holes 116 of the first part 111, the second part 112 and the third part 113, improving the installation efficiency.

[0036] Further, in a possible embodiment, as Figure 1 , Figure 3 shown, fixing grooves 1110 are provided on the waists of the outer side walls of the first part 111, the second part 112 and the third part 113, and the fixing grooves 1110 are used to fix the first part 111, the second part 112 and the third part 113.

[0037] The advantages of the above embodiments are as follows: by providing the fixing grooves 1110 on the first part 111, the second part 112 and the third part 113, an elastic member such as an elastic rope can be sleeved in the grooves. On the one hand, the first part 111, the second part 112 and the third part 113 can be simply fixed to prevent misalignment and make it impossible to be split and combined by the coil 121 and the magnet 122. On the other hand, since the elastic rope itself has the characteristic of combining the first part 111, the second part 112 and the third part 113, on this basis, those skilled in the art only need to set the magnetic fields of the coil 121 and the magnet 122 to be mutually repulsive, that is, only need to energize the coil 121 in a single direction, reducing the equipment cost.

[0038] In addition, regarding the setting method of the coil 121 and the magnet 122 on the first part 111, the second part 112 and the third part 113 mentioned above, those skilled in the art can make changes according to actual needs. The coil 121 can be set on the first part 111, the magnet 122 can be set at the first end of the second part 112, the coil 121 can be set at the second end of the second part 112, and the magnet 122 can be set on the third part 113. These changes do not exceed the technical principle of the present invention, so they will also be included in the protection scope of the present invention.

[0039] It should be noted that the above embodiments are only used to illustrate the principle of the present invention and are not intended to limit the protection scope of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0040] In addition, the present utility model further provides an air conditioner, which has the fixing structure 1 for the air conditioner compressor gas pipeline described in any one of the above embodiments.

[0041] So far, the technical solution of the present utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present utility model.
