DETAILED DESCRIPTION

[0024] The present application will be described in detail below with reference to specific embodiments shown in the drawings. However, these embodiments do not limit the present application, and any changes in structure, method, or function made by those of ordinary skill in the art based on these embodiments are included in the protection scope of the present application.

[0025] It should be understood that the terms such as "upper", "above", "lower", "below", and the like used herein to indicate spatial relative positions are for the purpose of facilitating description to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The spatial relative position terms can be intended to include different orientations of the device in use or in operation other than the orientation shown in the drawings.

[0026] An embodiment of the present application provides a refrigeration device and a production method thereof. The refrigeration device emits less noise, and the internal noise reduction device almost does not occupy the internal available space, so the space utilization rate is high, and the user's use experience is greatly improved.

[0027] The refrigeration appliance of the present embodiment can be a refrigerator, such as Figure 5 The refrigeration appliance of the present embodiment is a refrigerator structure, and an internal refrigeration system is arranged therein. The refrigeration system has a flow circuit for circulating refrigerant flow. The refrigeration system includes a compressor, a condenser, a throttling pipeline, and an evaporator connected in sequence. At least the compressor is arranged in a press chamber 2. The press chamber 2 can be arranged at any position of the refrigerator, such as the bottom, the middle, or the top. In the present embodiment, the press chamber 2 is arranged at the bottom of the refrigerator. Figure 5The compressor compartment 2 is located at the bottom of the refrigerator.

[0028] This embodiment improves the noise radiated outward from the compressor chamber 2 to solve the noise problem in the prior art.

[0029] To clearly express the position and direction described in this embodiment, in this embodiment, up and down can be defined in the approximate direction of gravity when the refrigerator is placed on a horizontal ground. Since the compressor chamber 2 is located inside the refrigerator, the direction from the back of the refrigerator towards the refrigerator body is called back, the rear of the refrigerator is called front, and the two sides perpendicular to the front and back direction are called left and right.

[0030] A refrigeration device 100 according to this embodiment includes a compressor chamber 2 and a housing 3. The compressor chamber 2 is disposed within the housing 3, and a foaming space is provided between the compressor chamber 2 and the housing 3. The housing 3 is... Figure 5 The refrigerator has an outer shell and an inner liner. A foamed space is formed outside the inner liner and compressor compartment 2, inside the shell 3. This foamed space is used to inject foaming agent, providing insulation. The foamed space generally has a certain thickness to achieve this insulation effect. The compressor compartment 2 includes side walls 21 on both sides, a back panel, a bottom panel, and a cover plate. These panels together enclose the cavity 20 of the compressor compartment 2. Inside the cavity 20 are a compressor, condenser, fan, and drip tray. The compressor compartment 2 includes an internal vent 210 connecting to the outside, and the shell 3 includes an external vent 31 opposite to the internal vent 210. These two vents allow heat to escape from the cavity 20.

[0031] The refrigeration equipment 100 also includes a sound-absorbing device 1 disposed within the foaming space, such as... Figures 1-4 As shown, the silencing device 1 is used to reduce the noise emitted by the cavity 20. The silencing device 1 includes a silencing channel 12, which connects the inner vent 210 and the outer vent 31. Preferably, the cavity 20 can only communicate with the outside world through the silencing channel 12, that is, the compressor chamber 2 is not directly connected to the outside world through other means. Since the foaming space itself must occupy a certain amount of space, installing the silencing device 1 in this position has several advantages:

[0032] Firstly, the silencer 1 no longer occupies space inside the inner liner or the compressor chamber 2, making the space utilization rate of the compressor chamber 2 higher, the structure can be made more compact, the space of the inner liner can be made larger, and the effective utilization rate of the refrigerator is higher. When users consider the refrigerator's smaller footprint and larger storage space, it becomes a favorable selling point for the refrigerator, increasing refrigerator sales and improving the user experience.

[0033] Secondly, the space position occupied by the sound-damping device 1 is the position where the compressor chamber 2 communicates with the outside and dissipates heat. The foaming at this position of the existing refrigerator will affect the heat dissipation of the compressor chamber 2. After the sound-damping device 1 is arranged at this position in the embodiment, the foaming material filled at this position will be reduced, thereby being more conducive to the heat in the compressor chamber 2 being dissipated outward from this position and being conducive to the cooling of the compressor chamber 2.

[0034] Thirdly, the foaming material itself has a fixed effect. After the foaming material is injected into the foaming space, the foaming material will tightly fix the sound-damping device 1 at the position after solidification, thereby reducing the vibration of the sound-damping device 1. The sound-damping device 1 itself is used to reduce noise, so it is necessary to stably fix the sound-damping device 1. Since the compressor is a rotating machine, it will vibrate during operation. The compressor is fixed on the bottom plate of the compressor chamber 2 and will drive the entire compressor chamber 2 to vibrate during operation. If the sound-damping device 1 is fixed in the compressor chamber 2, it cannot be stably fixed compared with being arranged in the foaming space. In addition, after a long time, the sound-damping device 1 will be loose under long-term vibration. However, the sound-damping device 1 is arranged in the foaming space and is fixed by the foaming material. The foaming material itself has a vibration-absorbing function and can stably fix the sound-damping device 1. The noise reduction effect is greatly improved and can be maintained in a stable state for a long time.

[0035] Fourthly, it does not affect the space structure design of the existing compressor chamber 2. The sound-damping device 1 can be installed on the premise that the space structure design, heat dissipation design, mechanical strength design, internal wiring design, and overall size of the refrigerator of the compressor chamber 2 are not changed. Since the position of the sound-damping device 1 has little or no spatial interference with the existing design, it is not necessary to make great adjustments to the existing structure. The production process, production parameter, and mold design are rarely changed. The refrigeration equipment 100 with the sound-damping device 1 can be transformed on the basis of the existing refrigeration equipment 100, thereby greatly reducing the production cost.

[0036] Fifthly, the noise reduction effect is good. The specific structure of the sound-damping device 1 is described below. After the sound enters the sound-damping device 1, it is transmitted along the sound-damping channel 12. A plurality of sound-damping cavities 15 are arranged on the side wall 21 of the sound-damping channel 12. The sound enters the inside of the sound-damping cavity 15 and propagates, thereby increasing the propagation path of the sound passing through the through hole, reducing the energy of the sound radiated outward, and achieving the noise reduction effect. The volume of the sound-damping cavity 15 can determine the frequency band of the sound that can be eliminated by the sound-damping cavity 15. Different sound-damping cavities 15 have different sound-damping frequency bands. Therefore, different sound-damping cavities 15 can be adjusted in volume, different frequencies of noise can be eliminated by the sound entering different sound-damping cavities 15, and the sound-damping device 1 has a wider sound-damping frequency.

[0037] Further, as shown in FIG. 6, the sound-damping device 1 can be arranged in the foaming space of the compressor chamber 2. Figure 1As shown, the left and right sides of the press chamber 2 are each provided with an inner vent 210, a sound attenuation device 1 corresponding to the inner vent 210, and an outer vent 31. One of the inner vents 210 is provided as an air inlet, and the other is provided as an air outlet. The press chamber 2 includes a cavity 20 and side walls 21 arranged on both sides of the cavity 20. The refrigeration equipment 100 includes a compressor arranged in the cavity 20. The inner vent 210 is arranged on the side wall 21 and communicates with the cavity 20. The sound attenuation device 1 is fixed to the side wall 21. In the prior art, the sound attenuation device 1 is arranged on the side wall 21 on the left and right sides of the press chamber 2. As shown in Figure 1 As shown, the air flow in and out of the cavity 20 passes through the sound attenuation device 1, which facilitates the air flow and reduces the noise directly transmitted outward at the air inlet and outlet.

[0038] Specifically, the side wall 21 is provided with a plurality of first clamping members 22. The sound attenuation device 1 includes a sound attenuation body 11 and a plurality of second clamping members 13 arranged on one side of the sound attenuation body 11 facing the side wall 21 and clamped with the first clamping members 22. The side wall 21 and the sound attenuation device 1 are fixedly connected by a fastener 4. The two are fixedly connected by clamping, and then tightly fixed by the fastener 4. The purpose is that the fastener 4, such as a bolt or a screw, can generally fix a few points, but the sealing performance of the position is very important. If the sealing performance is not good, the foaming material will enter the cavity 20 of the press chamber 2 through the gap. Therefore, the first clamping member 22 and the second clamping member 13 are connected in the form of clamping first. The first clamping member 22 and the second clamping member 13 can be arranged in the form of a ring or around the inner vent 210 to ensure that they can be fixed and sealed in the entire range.

[0039] The inner vent 210 and the outer vent 31 can be circular, so the first clamping member 22 and the second clamping member 13 can be distributed in the form of a circular ring, as shown in Figure 2 and 3 The first clamping member 22 includes a clamping hole 221 and a first clamping block 222. The second clamping member 13 includes a second clamping block 131 and a clamping groove 132. The clamping hole 221 and the first clamping block 222 are arranged in multiple groups around the inner vent 210, such as the four groups shown in the figure. The second clamping block 131 and the clamping groove 132 are correspondingly arranged in multiple groups around the inner vent 210, such as the four groups shown in the figure. The second clamping block 131 is connected to the first clamping block 222 through the clamping hole 221. The first clamping block 222 is fixed in the clamping groove 132 to fixedly connect the sound attenuation device 1 and the side wall 21.

[0040] During installation, the first clamping block 222 of the sound attenuation device 1 is inserted into the cavity 20 through the clamping opening 221 of the side wall 21, and then the sound attenuation device 1 is rotated to a certain angle, so that the first clamping block 222 of the side wall 21 is clamped into the clamping groove 132 of the sound attenuation device 1, and the clamping groove 132 is a groove formed between the second clamping block 131 and the sound attenuation body 11, thereby fixedly connecting in one whole circle. After being installed in place, the sound attenuation device 1 and the side wall 21 are fastened and connected through the fastener 4, so as to avoid separation of the two.

[0041] The flow channel 10 is arranged between the sound attenuation device 1 and the shell 3 and / or the side wall 21, as shown in the figure. Figure 4 The flow channel 10 communicates the foaming space above the sound attenuation device 1 with the foaming space below the sound attenuation device 1, so that the foaming material enters the lower or upper space through the flow channel 10 when the foaming agent is injected into the foaming space. As a result, the flow of the foaming agent is not hindered at the position where the sound attenuation device 1 is arranged, and the heat preservation performance in other foaming spaces is not affected.

[0042] Further, the sound attenuation device 1 is sealingly connected with the shell 3, and the sound attenuation device 1 comprises the sound attenuation body 11 and the protection member 14 arranged between the shell 3 and the sound attenuation body 11, as shown in the figure. Figures 1-3 The protection member 14 comprises a protection net 141 transversely arranged between the sound attenuation channel 12 and the outer vent 31, and the protection member 14 is clamped to the port of the sound attenuation channel 12. The protection member 14 is used to prevent insects, rats and the like in the external environment from entering the cavity 20, and does not affect the inflow and outflow of air. The protection member 14 is provided with buckles 142, which are clamped with the sound attenuation body 11, so that the assembly is convenient.

[0043] Further, the sound attenuation device 1 comprises a plurality of sound attenuation cavities 15 arranged on the path of the sound attenuation channel 12. The sound attenuation cavity 15 comprises an opening 151 facing the sound attenuation channel 12, and the volumes of at least two sound attenuation cavities 15 are different. At least part of the sound enters the sound attenuation cavity 15 through the opening 151. The sound attenuation cavity 15 has a certain depth, and the sound propagates inside the sound attenuation cavity 15 after entering the opening 151, so that the propagation path of the sound through the through hole is increased. By arranging the acoustic metamaterial, the noise reduction effect is achieved. The volume of the sound attenuation cavity 15 can determine the frequency band of the sound that can be eliminated by the sound attenuation cavity 15, that is, different sound attenuation cavities 15 have different sound attenuation frequency bands. Therefore, by adjusting the volumes of different sound attenuation cavities 15, different frequencies of noise can be eliminated by entering different openings 151, so that the sound attenuation device 1 has a wider sound attenuation frequency.

[0044] In addition, an embodiment of the present application provides an assembling method of the refrigeration equipment 100. The refrigeration equipment 100 is the refrigeration equipment 100 described above, and the assembling method comprises the following steps:

[0045] The sound attenuation device 1 is fixedly connected in the foaming space outside the press machine bin 2.

[0046] The mounting shell 3 is installed in the foaming space.

[0047] The foaming agent is injected into the foaming space.

[0048] That is, the soundproofing device 1 is first fixed in the foaming space, and then the foaming agent is injected into the foaming space, so that the foaming agent firmly fixes the soundproofing device 1 in the foaming space, thereby achieving the beneficial effects of the above-mentioned "foaming material itself has a fixing effect".

[0049] Compared with the prior art, the embodiment has the following beneficial effects:

[0050] By arranging the soundproofing device 1 in the foaming space, since it is inevitable that the foaming space occupies a part of the space, the space is not used to occupy the space inside the refrigeration equipment 100, and the press machine warehouse 2 is connected with the outside through the soundproofing channel 12, so that the sound energy is weakened in the process of heat dissipation to the outside, and the noise radiated to the outside is reduced, so that the scheme achieves a good balance between noise reduction and space occupation of the refrigeration equipment 100, the noise emitted by the refrigeration equipment 100 is small, the space utilization rate is high, and the user's use experience is greatly improved.

[0051] It should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.

[0052] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present application, and they are not used to limit the protection scope of the present application, and any equivalent embodiments or changes made without departing from the spirit of the present application should be included in the protection scope of the present application.
