Technical Field

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

[0002] In recent years, most household variable-frequency units have had the problem of noise reduction, especially household air source heat pump units of around 50kw, which may be installed near residential buildings in China. Because the current domestic real estate development has reached a state of sky-high land prices, this trend will become more serious in the future. If the noise is too loud, it will affect the normal use of the product.

[0003] Especially in variable frequency units, the full-frequency operation of the variable frequency compressor will emit noise of various qualities. Traditional noise reduction solutions can only weaken one quality of noise, which cannot meet the needs of full-frequency noise reduction operation of the air conditioner. Summary of the Invention

[0004] An embodiment of the present invention provides an air-conditioning unit to solve the technical problem that the shell noise reduction technology in the prior art cannot meet the noise reduction requirements of the air-conditioning unit when operating at different frequencies.

[0009] In one embodiment, a matching portion is formed on the noise reduction frequency adjustment member, and the matching portion matches with the unblocked portion of the noise reduction hole to form a noise reduction opening.

[0010] In one embodiment, the matching portion is arc-shaped, and the arc-shaped matching portion and the unblocked portion of the noise reduction hole form a circular or elliptical noise reduction opening.

[0011] In one embodiment, the noise reduction housing further comprises: a driving member connected to the noise reduction frequency adjusting member and configured to drive the noise reduction frequency adjusting member to move on the housing.

[0012] In one embodiment, the driving member includes a motor and a connecting rod, a first end of the connecting rod is connected to the output shaft of the motor, and a second end of the connecting rod is connected to the noise reduction frequency adjustment member.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0022] Figure 1 The embodiment of the noise reduction shell of the present invention is shown, which includes a shell 10 and a noise reduction frequency adjustment member 20. A noise reduction hole 11 is opened on the shell 10, and the noise reduction frequency adjustment member 20 is movably arranged on the shell 10 for adjusting the opening of the noise reduction hole 11.

[0023] By applying the technical solution of the present invention, a noise reduction hole 11 is opened on the shell 10. According to different operating frequencies of the air-conditioning unit, the opening of the noise reduction hole 11 is adjusted by the noise reduction frequency adjustment member 20, thereby controlling the attenuation volume of the noise reduction hole 11 to adapt to different operating frequencies of the air-conditioning unit.

[0024] It should be noted that, in the technical solution of this embodiment, only one of the multiple noise reduction holes 11 on the shell 10 is used as an example, and the other noise reduction holes 11 on the shell 10 can also use the technical solution of this embodiment.

[0025] like Figure 1 As shown, in the technical solution of this embodiment, the noise reduction frequency adjustment member 20 is slidably mounted on the housing 10, and the noise reduction frequency adjustment member 20 adjusts the opening of the noise reduction hole 11 by sliding to block the size of the portion of the noise reduction hole 11. Preferably, in the technical solution of this embodiment, a slide groove 12 is formed on the housing 10, and the noise reduction frequency adjustment member 20 is mounted in the slide groove 12. Figure 1 For example, when the noise reduction frequency adjustment member 20 slides upward along the chute 12, the opening of the noise reduction hole 11 is reduced; when the noise reduction frequency adjustment member 20 slides downward along the chute 12, the opening of the noise reduction hole 11 is increased. More preferably, the chute 12 is a T-shaped chute, and the noise reduction frequency adjustment member 20 is mounted in the T-shaped chute. The T-shaped chute not only facilitates the sliding of the noise reduction frequency adjustment member 20, but also serves as a mounting mechanism for the noise reduction frequency adjustment member 20.

[0026] In other optional embodiments, the noise reduction frequency adjustment member 20 may also be rotatably and slidably mounted on the housing 10 .

[0027] like Figure 1 and Figure 2 As shown, a fitting portion 21 is formed on the noise reduction frequency adjustment member 20. The fitting portion 21 cooperates with the unobstructed portion of the noise reduction hole 11 to form a noise reduction opening. Adjusting the size of the noise reduction opening is equivalent to adjusting the opening of the noise reduction hole 11. More preferably, the fitting portion 21 is arc-shaped, and the arc-shaped fitting portion 21 and the unobstructed portion of the noise reduction hole 11 form a circular or elliptical noise reduction opening. As another optional embodiment, if the noise reduction hole 11 is a square hole, the fitting portion 21 can also be linear, and the arc-shaped fitting portion 21 and the unobstructed portion of the noise reduction hole 11 form a rectangular noise reduction opening.

[0028] like Figure 2 and Figure 3As shown, in the technical solution of this embodiment, the noise reduction shell also includes a driving member 30, which is connected to the noise reduction frequency adjustment member 20 and is used to drive the noise reduction frequency adjustment member 20 to move on the shell 10. Optionally, in the technical solution of this embodiment, the driving member 30 includes a motor 31 and a connecting rod 32, the first end of the connecting rod 32 is connected to the output shaft of the motor 31, and the second end of the connecting rod 32 is connected to the noise reduction frequency adjustment member 20. Optionally, the connecting rod 32 includes a rocker 321 and a transmission rod 322, the first end of the rocker 321 is fixedly connected to the output shaft of the motor 31, the second end of the rocker 321 is hinged to the first end of the transmission rod 322, and the second end of the transmission rod 322 is hinged to the noise reduction frequency adjustment member 20. When in use, the output shaft of the motor 31 rotates, driving the rocker 321 to swing in a circle, and then driving the transmission rod 322 to extend or retract, so that the noise reduction frequency adjustment member 20 slides on the shell 10. As shown Figure 4 As shown in FIG. 1 , it is a process in which the driving member 30 drives the noise reduction frequency adjusting member 20 to adjust the opening of the noise reduction hole 11 to become larger.

[0029] As another optional implementation, an electric push rod or a movable cylinder may also be used to drive the noise reduction frequency adjustment member 20 to move.

[0030] The present invention further provides an air conditioning unit including the aforementioned noise reduction housing. The air conditioning unit using the aforementioned noise reduction housing can reduce noise at different operating frequencies, thereby enabling the air conditioning unit to better meet customer needs for low-noise operation.

[0031] It should be noted that the above-mentioned technical solution of the air-conditioning unit is particularly suitable for variable frequency units.

[0032] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
