Here, the fan 30 can drive the air flow to flow into the compressor compartment, exchange heat with the compressor 10 and/or the condenser 20 in the compressor compartment, and then flow out of the compressor compartment, thereby achieving heat dissipation to the compressor 10 and the condenser 20.

Optionally, as shown in fig. 1 and 2, the air intake passage 401 and/or the air outlet passage 404 are configured with a muffler device 505.

In this embodiment, the airflow in the press cabin mainly flows through the air inlet channel 401 and the air outlet channel 404, and the muffler device 505 is disposed in the air inlet channel 401 and/or the air outlet channel 404, so that when the airflow flows through the air inlet channel 401 and/or the air outlet channel 404, the muffler device 505 can absorb noise in the airflow. Meanwhile, the noise of the compressor 10 and the fan 30 can be absorbed by the muffler 505 in the process of outward transmission, so that the muffler 505 can cut off the transmission path of the noise, and the effects of sound absorption and sound insulation are achieved, thereby reducing the overall noise of the refrigerator.

Optionally, the press cabin comprises a bottom plate 40 and an air duct plate 50, the bottom plate 40 being located at the bottom of the press cabin; the air duct plate 50 is located above the bottom plate 40, the number of the air duct plates 50 is multiple, the air duct plates 50 enclose a plurality of silencing cavities 501, the silencing cavities 501 are arranged above the bottom plate 40 at intervals, an air duct is formed between adjacent silencing cavities 501, through holes 502 are formed in the silencing cavities 501 towards the side wall of the air duct, and the silencing device 505 comprises the silencing cavities 501 and the through holes 502.

When the frequency of the incident sound wave is consistent with the natural frequency of the resonator structure, the generated resonance amplitude is maximum, and the consumed energy is the largest.

Optionally, as shown in fig. 2, the refrigerator further includes a sound absorbing material 801, and the sound absorbing material 801 is disposed in the sound attenuation chamber 501.

In this embodiment, the sound absorbing material 801 is located in the sound absorbing cavity 501, and can absorb the sound energy in the airflow, so as to play a role in noise elimination and noise reduction.

Optionally, the sound absorbing material 801 abuts the perforations 502 such that sound waves pass through the perforations 502 and the sound absorbing material 801 into the sound attenuation chamber 501.

Optionally, when air channels are disposed on two sides of the sound-deadening cavity 501, the refrigerator further includes a middle partition board 80, the middle partition board 80 is located in the sound-deadening cavity 501, the middle partition board 80 divides the sound-deadening cavity 501 into two cavities, each cavity is provided with a perforation 502 and a sound-absorbing material 801, so as to form two helmholtz resonance structures, and the two helmholtz resonance structures are corresponding to and communicated with the air channels on two sides of the sound-deadening cavity 501.

In this embodiment, when the two sides of the sound-absorbing cavity 501 are all provided with air channels, the two sides of the sound-absorbing cavity 501 facing the air channels are all provided with the sound-absorbing device 505, so that the air channels on the two sides of the sound-absorbing cavity 501 can be both subjected to sound-absorbing and noise-reducing, and the sound-absorbing and noise-reducing effects are further achieved.

It should be noted that: when the multiple sides of the muffling cavity 501 are all provided with air channels, the muffling cavity 501 can be divided into multiple helmholtz resonating structures, which can muffling and noise reducing the multiple air channels.

Optionally, the compressor 10 and the condenser 20 are located at the rear end of the bottom plate 40, the air ducts extend in the front-rear direction, the air inlet of the air inlet channel 401 is located at the front end of the air inlet channel 401, and/or the air outlet of the air outlet channel 404 is located at the front end of the air outlet channel 404.

In this embodiment, the cabin and the condenser 20 are located at the rear end of the bottom plate 40, the air inlet channel 401 and the air outlet channel 404 extend along the front-rear direction, and the air flows along the front-rear direction, so that the air flow can be prevented from flowing in other directions, the radiation of noise is reduced, and the noise elimination and reduction effect is further improved.

Optionally, as shown in fig. 3 to 5, the refrigerator further includes a back plate 60, and the back plate 60 is connected to the rear end of the bottom plate 40 and extends upward so that the rear end of the press cabin is closed.

Meanwhile, the installation position of the double-suction centrifugal fan 301 is the same as that of the existing axial flow fan 30, and two centrifugal fans 30 are not required to be installed in the press cabin, so that the occupied space of the fans 30 can be reduced, and the structural complexity of the refrigerator is reduced.

In addition, when the refrigerator is an embedded refrigerator, the refrigerator needs to be embedded into the cabinet, and for noise of the refrigerator, as four faces (left, right, back and top) are all shielded by the cabinet panel, sound waves can be completely transmitted to the air from the front end of the refrigerator through superposition. The sound wave is reflected in a series in a narrow space of the cabinet, and is transmitted out from the front end through superposition, so that the noise value of the front end is increased. The compressor 10 is located at the bottom of the refrigerator and is the most dominant source of noise. In the prior art, an axial flow fan is generally adopted for heat dissipation, and the noise of the axial flow fan is large. According to the embodiment of the disclosure, the working wind pressure of the double-suction centrifugal fan 301 is larger, turbulence is avoided, the wind outlet is uniform, the working noise of the double-suction centrifugal fan 301 is smaller, and the noise of a refrigerator can be reduced.

While the ambient air flows through the condenser 20, then flows into the first fan chamber from the second inlet, and then flows out from the outlet 3013. That is, the double suction centrifugal fan 301 achieves cooling and heat dissipation of the condenser 20 and the compressor 10, respectively, through the first inlet 3011, the second inlet and the outlet 3013.

Optionally, the number of the air intake channels 401 is multiple, and the multiple air intake channels 401 include a first air intake channel 402 and a second air intake channel 403, where the first air intake channel 402 is communicated with the first inlet 3011, and the dual-suction centrifugal fan 301 drives external air to flow through the first air intake channel 402, flow through the compressor 10, the first inlet 3011 and the impeller sequentially after flowing in, and then flow out from the outlet 3013.

In this embodiment, the air inlet channels 401 are divided into two, and the two air inlet channels 401 can avoid the mutual interference of the air flows of the first inlet 3011 and the second inlet, and can ensure the air quantity flowing to the compressor 10 and the condenser 20. In fig. 3, the bold arrow indicates the airflow direction of the first air intake channel 402, the dotted arrow indicates the airflow direction of the second air intake channel 403, and the thin arrow indicates the airflow direction of the air outlet channel 404.

Alternatively, the first air inlet channel 402 is located at a side of the first inlet 3011 facing the compressor 10, and the number of the first air inlet channels 402 is plural, and the plural first air inlet channels 402 are sequentially spaced along the direction from the compressor 10 to the double suction centrifugal fan 301.

In this embodiment, the first air inlet channel 402 is located at a side of the first inlet 3011 facing the compressor 10, so that the flow path of the air flow can be reduced, and the air flow flowing to the first inlet 3011 and the air flow flowing to the second inlet are prevented from interfering with each other. The provision of the plurality of first air intake passages 402 can increase the amount of intake air and improve the heat dissipation effect to the compressor 10.

Optionally, the second air inlet channel 403 is located at a side of the second inlet towards the condenser 20, and the number of the second air inlet channels 403 is plural, and the plural second air inlet channels 403 are sequentially spaced from each other along the direction from the condenser 20 to the double suction centrifugal fan 301.

And the arrangement of the plurality of second air inlet channels 403 can increase the air inlet quantity of the second inlet, so as to improve the heat dissipation effect of the condenser 20.

Optionally, an air outlet channel 404 is located between the first air inlet channel 402 and the second air inlet channel 403.

In this embodiment, the double suction centrifugal fan 301 is located between the condenser 20 and the compressor 10, and the outlet 3013 is located at the bottom of the double suction centrifugal fan 301, so that the air outlet channel 404 is located between the first air inlet channel 402 and the second air inlet channel 403, so as to facilitate the air outlet of the double suction centrifugal fan 301.

In this embodiment, the double suction centrifugal fan 301 of the present application can improve the heat dissipation effect on the compressor 10 and the condenser 20 through the multi-inlet and single-outlet air duct structure of the bottom plate 40, and can also reduce the noise of the fan 30 running.

It should be noted that: the number of the air outlet channels 404 may be plural, and the air outlet channels 404 are all communicated with the outlet 3013 of the double-suction centrifugal fan 301, so as to increase the air volume.

In other alternative embodiments, as shown in fig. 4 and 5, blower 30 includes a double suction cross flow blower 302, and double suction cross flow blower 302 includes a second housing defining a second blower 30 cavity and a third blower 30 cavity, second blower 30 cavity having a third inlet and a first outlet 3013, and third blower 30 cavity having a fourth inlet and a second outlet 3013. The double suction cross flow fan 302 further comprises a second impeller, a third impeller and a motor, wherein the second impeller is positioned in the first fan cavity; the third impeller is positioned in the cavity of the second fan 30 and is coaxially arranged with the second impeller; the motor is connected between the second impeller and the third impeller, and the motor is used for driving the second impeller and the third impeller to rotate.

In this embodiment, the double suction cross flow fan 302 has two inlets and two outlets 3013, that is, the air flows can flow in from the two inlets and then flow out from the two outlets 3013, respectively. Thus, when the double-suction cross-flow fan 302 is applied to a refrigerator, the condenser 20 and the compressor 10 in the compressor cabin can flow into the double-suction cross-flow fan 302 from two inlets respectively, then flow out from two outlets 3013, and heat dissipation of the condenser 20 and the compressor 10 can be realized through one double-suction cross-flow fan 302 respectively, so that the heat dissipation effect in the compressor cabin is improved. The problem of poor heat dissipation effect of the compressor 10 caused by small temperature difference between the air flow and the surface of the compressor 10 due to the fact that the air flow firstly flows through the condenser 20 and then flows through the compressor 10 in the prior art can be avoided. Meanwhile, the positions of all parts in the press cabin do not need to be improved, two fans 30 do not need to be additionally arranged, the heat dissipation effect can be improved, meanwhile, the occupied space of the fans 30 can be reduced, and the complexity of the refrigerator is reduced.

The number of the air inlet channels 401 is multiple, the air inlet channels 401 comprise a third air inlet channel 407 and a fourth air inlet channel 408, the third air inlet channel 407 is communicated with a third inlet, and the fourth air inlet channel 408 is communicated with a fourth inlet. That is, each inlet is correspondingly provided with an air inlet channel 401, so that the air flows of the two inlets are prevented from interfering with each other. Specifically, the third air intake passage 407 is located on a side of the third inlet facing the compressor 10, and the fourth air intake passage 408 is located on a side of the fourth inlet facing the condenser 20.

In this way, the airflows flowing out from the two outlets 3013 of the double-suction cross-flow fan 302 flow out from the two air outlet channels 404 respectively, so that the air output of the double-suction cross-flow fan 302 can be ensured.

The solid arrows in fig. 4 indicate the flow direction of the air flow of the third air intake passage 407, the compressor 10, the double suction cross flow fan 302, and the first air outlet passage 405.
