Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a liquid dispenser and a refrigeration device. Background Art

[0002] Air conditioners can make abnormal noise during use. The main sources of noise in the indoor unit are fluorine flow noise, indoor unit anomalies, indoor unit motor anomalies, thermal expansion and contraction, and uneven air flow. Fluorine flow noise is the noise that most affects the user experience. Fluorine flow noise refers to the noise generated by the flow of refrigerant in the pipes, and is particularly noticeable in the liquid distributor. Related technologies attempt to reduce the noise level by wrapping damping blocks or soundproofing cotton around the liquid distributor. However, the relatively small installation space inside the indoor unit makes installing the soundproofing cotton or damping blocks more difficult, and larger soundproofing cotton or damping blocks cannot be used for wrapping, resulting in a poor noise reduction effect on the air conditioner's noise.

[0011] In some embodiments, the diameter of the noise reduction hole is greater than or equal to 0.05 mm and less than or equal to 0.5 mm.

[0012] In some embodiments, the cross-section of the noise reduction hole is rectangular, polygonal, or circular.

[0013] In some embodiments, the noise reduction hole is arranged to extend along the axial direction of the shell.

[0014] In some embodiments, the noise reduction holes are arranged to extend radially along the shell.

[0015] In some embodiments, the noise reduction hole extends around the axis of the shell.

[0016] In some embodiments, an axis of the noise reduction hole and an axis of the shell form an angle, and the angle is an acute angle.

[0017] In some embodiments, the liquid dispenser is made of metal, and the shell and the noise reduction interlayer are integrally formed.

[0018] In some embodiments, the noise reduction interlayer is formed by additive manufacturing.

[0019] In some embodiments, the diversion chamber is provided with a liquid inlet section, a liquid separation section and multiple liquid outlet sections connected in sequence, one side of the shell is provided with a liquid inlet connected to the liquid inlet section, and the other side is provided with multiple liquid outlets, and the liquid outlets are connected to the liquid outlet sections one by one.

[0020] On the other hand, an embodiment of the present application provides a refrigeration device, including the liquid separator as described above.

[0021] In an embodiment of the present application, the liquid distributor includes a shell and a noise reduction interlayer. A diversion chamber is provided in the shell, and the diversion chamber is used for circulating refrigerant. A noise reduction interlayer is provided between the outer wall of the diversion chamber and the inner wall of the shell. The noise reduction interlayer extends around the outer wall of the diversion chamber. Noise is generated when the refrigerant rubs against the cavity wall of the diversion chamber. When the refrigerant flows into the diversion chamber, the flow path changes, and the friction between the refrigerant and the cavity wall will cause the noise to increase. Because the noise reduction interlayer is provided around the outer wall of the diversion chamber, the noise reduction interlayer can absorb or consume noise in time, so that the noise transmitted to the outside of the shell is reduced. In this way, the liquid distributor chamber and the noise reduction interlayer are provided in the same shell, that is, there is no need to provide sound insulation cotton on the outside of the shell to achieve noise reduction. Compared with the embodiment where the space is too small to install sound insulation cotton on the outside of the liquid distributor, the noise reduction effect of the air conditioner equipped with the liquid distributor can be enhanced.

It should be understood that one of ordinary skill in the art can recognize that the present application can be implemented without using these specific details.

Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0033] On the one hand, an embodiment of the present application provides a liquid dispenser, including a shell 1 and a noise reduction interlayer 2; a diversion chamber 3 is provided in the shell 1; the noise reduction interlayer 2 is arranged in the shell 1 and located outside the diversion chamber 3, and the noise reduction interlayer 2 is arranged around the outer wall of the diversion chamber 3.

[0034] Among them, the air conditioner will produce abnormal noise during use, especially when the noise occurs indoors, it greatly affects the user's living environment and office environment. The main sources of noise in the indoor unit are fluorine flow noise, indoor unit abnormalities, indoor unit motor abnormalities, thermal expansion and contraction, uneven air output, etc. Among them, fluorine flow noise accounts for the largest proportion of all noise sources and is the noise source that most affects the user's experience. Fluorine flow noise refers to the noise generated by the flow of refrigerant in the pipeline. The location where fluorine flow noise is generated is usually in the indoor unit evaporator pipeline, distributor and the bend of the pipeline. The fluorine flow noise generated in the distributor is the most obvious; in the related technology, the space inside the air conditioner shell 1 is small, the distributor is welded on the flow path of the refrigerant, and the space around the distributor is very small. It is difficult for assemblers to wrap thicker sound insulation cotton on the distributor, resulting in poor noise reduction effect.

[0035] In an embodiment of the present application, the liquid separator includes a shell 1 and a noise reduction interlayer 2. A diverter chamber 3 is provided in the shell 1. The diverter chamber 3 is used for circulating refrigerant. A noise reduction interlayer 2 is provided between the outer wall of the diverter chamber 3 and the inner wall of the shell 1. The noise reduction interlayer 2 extends around the outer wall of the diverter chamber 3. Noise is generated when the refrigerant rubs against the cavity wall of the diverter chamber 3. When the refrigerant flows into the diverter chamber 3, the flow path changes, and the friction between the refrigerant and the cavity wall will cause the noise to increase. Because the noise reduction interlayer 2 is provided around the outer wall of the diverter chamber 3, the noise reduction interlayer 2 can absorb or consume noise in time, so that the noise transmitted to the outside of the shell 1 is reduced. In this way, the liquid separator chamber and the noise reduction interlayer 2 are provided in the same shell 1, that is, there is no need to provide sound insulation cotton outside the shell 1 to achieve noise reduction. Compared with the embodiment where the space is small and sound insulation cotton cannot be installed outside the liquid separator, the noise reduction effect of the air conditioner equipped with the liquid separator can be enhanced.

[0036] In some embodiments, a plurality of noise reduction holes 21 are provided in the noise reduction interlayer 2 .

[0037] Specifically, when the noise waves are transmitted outward, they will pass through multiple noise reduction holes 21. The hole wall of each noise reduction hole 21 can reflect the sound waves. The more noise reduction holes 21 there are, the more sound waves are reflected. After multiple reflections, the sound waves will gradually attenuate, thereby achieving the purpose of reducing noise. This arrangement can enhance the noise reduction effect of the noise reduction interlayer 2, thereby enhancing the noise reduction effect of the liquid separator. In some other embodiments, multiple resonance plates are provided in the noise reduction interlayer 2. The natural frequency of the resonance plates is close to the frequency of the sound waves transmitted to the noise reduction interlayer 2. The strong vibration of the resonance plates consumes the sound energy of the sound waves, thereby achieving the purpose of reducing noise.

[0038] In some embodiments, the plurality of noise reduction holes 21 are spaced apart from each other.

[0039] Specifically, the multiple noise reduction holes 21 in the noise reduction interlayer 2 are arranged at uniform intervals, that is, the multiple noise reduction holes 21 together form a regular lattice structure. In this way, the production difficulty of the noise reduction interlayer 2 can be reduced and the production cost can be reduced; the multiple noise reduction holes 21 can also be arranged at uneven intervals, that is, together form an irregular lattice structure. This arrangement can set more noise reduction holes 21 at locations with stronger noise energy, so that the intervals between the noise reduction holes 21 are small, and the frequency and number of sound wave reflections are increased, thereby improving the noise reduction effect.

[0040] In another embodiment, a plurality of noise reduction holes 21 are arranged to communicate with each other.

[0041] Specifically, the multiple noise reduction holes 21 in the noise reduction interlayer 2 are connected to each other. The multiple noise reduction holes 21 can be connected in sequence to form an irregularly shaped long strip noise reduction hole 21, or the multiple honeycomb-shaped noise reduction holes 21 can be connected to each other. This arrangement can make the sound wave reflect farther in the noise reduction hole 21, thereby increasing the sound energy consumption of the sound wave to achieve the purpose of noise reduction.

[0042] In some embodiments, the porosity of the noise reduction interlayer 2 is greater than or equal to 20% and less than or equal to 80%.

[0043] Specifically, the porosity refers to the percentage of the volume of the noise reduction holes 21 to the overall volume of the noise reduction interlayer 2. The porosity is 20%, 30%, 40%, 50%, 60%, 70% or 80%. The greater the porosity, the more noise reduction holes 21 there are. The number of noise reduction holes 21 in the noise reduction interlayer 2 is determined based on the noise level. If the noise generated by the flow of the refrigerant is large, more noise reduction holes 21 need to be set to improve the noise reduction effect. If the noise is small, the setting of the noise reduction holes 21 can be adaptively reduced. Such a setting can improve the universality of the dispenser, and dispensers of different specifications can be selected according to different models. In some other embodiments, the porosity of the noise reduction interlayer 2 is greater than 80%.

[0044] In some embodiments, the diameter of the noise reduction hole 21 is greater than or equal to 0.05 mm and less than or equal to 0.5 mm.

[0045] Specifically, the aperture of the noise reduction hole 21 is 0.05mm, 0.10mm, 0.15mm, 0.20mm, 0.25mm, 0.30mm, 0.35mm, 0.40mm, 0.45mm or 0.50mm; the aperture of the noise reduction hole 21 is determined according to the size of the noise, and the volume of the noise reduction interlayer 2 is also determined according to the volume of the shell 1. When the volume of the noise reduction interlayer 2 is large enough, the aperture of the noise reduction hole 21 can be increased to obtain a better noise reduction effect, or the noise reduction effect can be improved by providing a large number of noise reduction holes 21 with small apertures. This arrangement makes the structure of the noise reduction interlayer 2 more adaptable and can be designed according to different objective conditions to improve universality. In some other embodiments, the aperture of the noise reduction hole 21 is greater than 0.5mm.

[0046] In some embodiments, the cross-section of the noise reduction hole 21 is rectangular, polygonal, or circular.

[0047] Specifically, the cavity in the noise reduction hole 21 can be in various forms, such as: cubic, spherical, etc., and the cross-section of the noise reduction hole 21 can be divided from the middle part of the dispenser. It can be rectangular, polygonal or circular. The cross-sectional area of ​​noise reduction holes 21 of different shapes is different, and the reflection effect of sound waves is different. In this way, the shape of the noise reduction hole 21 can be designed according to different needs.

[0048] In some embodiments, the noise reduction hole 21 is arranged to extend along the axial direction of the housing 1 .

[0049] Specifically, the shell 1 is cylindrical, the axial direction of the shell 1 is the up-down direction, the noise reduction hole 21 extends in the up-down direction, and the noise reduction hole 21 can be extended into a long strip-shaped hole.

[0050] In another embodiment, the noise reduction hole 21 is provided to extend along the radial direction of the housing 1 .

[0051] Specifically, the radial direction of the cylindrical shell 1 is the left-right direction or the front-back direction, and the noise reduction hole 21 can extend in the left-right direction, or in the front-back direction, or part of the noise reduction hole 21 can extend in the left-right direction and part of the noise reduction hole 21 can extend in the front-back direction.

[0052] In another embodiment, the noise reduction hole 21 extends around the axis of the housing 1 .

[0053] Specifically, the noise reduction hole 21 extends around the axis of the shell 1 to form a ring, which can be a closed ring or an open ring. The noise reduction hole 21 can also extend into a torsion spring shape. Regardless of the extension method, the noise reduction hole 21 surrounds the diversion cavity 3.

[0054] In another embodiment, the axis of the noise reduction hole 21 and the axis of the housing 1 form an acute angle.

[0055] Specifically, the noise reduction hole 21 is tilted within the noise reduction interlayer 2. This creates an acute angle between the axis of the noise reduction hole 21 and the axis of the housing 1. Different extensions of the noise reduction hole 21 can provide different noise reduction effects, and the desired extension should be tailored to the specific situation.

[0056] In some embodiments, the liquid dispenser is made of metal, and the shell 1 and the noise reduction interlayer 2 are integrally formed.

[0057] Specifically, the entire liquid dispenser is made of metal, which can be copper, stainless steel, aluminum alloy, or titanium alloy. In this embodiment, the liquid dispenser is made of copper, and the shell 1 and the noise reduction interlayer 2 are formed together through one-piece molding. When the shell 1 is formed, the liquid separation cavity can be directly formed. This arrangement can reduce production costs, and the connection between the multiple structures is tighter without gaps, thereby improving the overall strength and service life of the liquid dispenser. In some other embodiments, the noise reduction interlayer 2 is welded inside the shell 1.

[0058] In some embodiments, the noise reduction interlayer 2 is formed by additive manufacturing.

[0059] Specifically, the noise reduction interlayer 2 is formed by 3D printing, and a plurality of noise reduction holes 21 are directly formed during the printing process. This arrangement can ensure that the overall strength of the noise reduction interlayer 2 is high and the consistency of the plurality of noise reduction holes 21 can be ensured.

[0060] In the embodiment where the shell 1 and the noise reduction interlayer 2 are integrally formed, the shell 1 and the noise reduction interlayer 2 are jointly manufactured by 3D printing, i.e., the liquid separation cavity and the noise reduction hole 21 are jointly formed by 3D printing. This arrangement can further ensure the overall strength and structural consistency of the liquid dispenser.

[0061] In some embodiments, the diversion chamber 3 is provided with a liquid inlet section 31, a liquid separation section 32 and multiple liquid outlet sections 33 that are connected in sequence. One side of the shell 1 is provided with a liquid inlet 11 connected to the liquid inlet section 31, and the other side is provided with multiple liquid outlets 12, and the liquid outlets 12 are connected to the liquid outlet sections 33 one by one.

[0062] Specifically, a liquid inlet 11 is provided at the upper end of the shell 1, and a plurality of liquid outlets 12 are provided at the lower end of the shell 1. In the present embodiment, there are three liquid outlets 12 at the bottom. The number of the liquid outlets 12 can be changed according to actual diversion requirements. A plurality of liquid outlet sections 33 are set according to the number of liquid outlets 12. The plurality of liquid outlets 12 are axially symmetrically distributed, that is, the plurality of liquid outlets 12 are evenly spaced circumferentially along the central axis of the liquid inlet section 31. The noise reduction interlayer 2 is located between the shell and the liquid inlet section 31, the liquid separation section 32, and the plurality of liquid outlet sections 33. The liquid separation section 32 includes a plurality of branches, which are connected to the liquid outlet sections 33 one by one. The liquid inlet section 31 is respectively connected to the liquid separation section 32 and the liquid inlet 11. The liquid separation section 32 is used to change the flow direction of the refrigerant. The liquid inlet section 31 bulges upward and protrudes from the upper surface of the shell 1, forming a convex column structure at the top of the shell 1, which is used for welding.

[0063] In some embodiments, edges of the liquid inlet 11 and the liquid outlet 12 are both chamfered.

[0064] Specifically, a chamfer is provided at the liquid inlet 11 to reduce the diameter, and a chamfer is provided at the liquid outlet 12 to expand the diameter of each liquid outlet 12. This arrangement can make the refrigerant entering the liquid separator faster and the refrigerant flowing out of the liquid separator flow smoother.

[0065] On the other hand, an embodiment of the present application provides a refrigeration device, including the liquid separator as described above.

[0066] Specifically, the refrigeration equipment is an indoor air conditioner, and the liquid distributor is installed in the indoor air conditioner. In this way, the liquid distributor can be directly welded and used, and there is no need to add additional sound insulation cotton or other noise reduction structures on the outside.

[0067] The above is a detailed introduction to the liquid dispenser and refrigeration equipment provided in the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for those skilled in the art, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope.
