Fig. 1 is a schematic structural view of a compressor cartridge for a refrigerator according to an embodiment of the present utility model, and in combination with fig. 2, the present utility model provides a compressor cartridge for a refrigerator including a first housing 2 and a heat transfer pad 4. The first housing 2 defines a sealed vacuum space 3 therein, and the sealed vacuum space 3 is provided for mounting the compressor 1 of the refrigerator therein. One surface of the heat transfer foot pad 4 is in contact with and abuts against the end face of the mounting post of the compressor 1, and the other surface of the heat transfer foot pad 4 is in contact with and abuts against the inner wall of the bottom wall of the first casing 2.

In the present embodiment, as shown in fig. 1, a compressor 1 is used to circulate a refrigerant to cool a refrigerator compartment. The first housing 2 has a sealed vacuum space 3 therein, and the sealed vacuum space 3 may be directly surrounded by a peripheral wall of the first housing 2 or may be formed by other structures in the first housing 2. The sealed vacuum space 3 does not contain air or has a low air content, that is, has a high vacuum degree. In the prior art, vibration and noise of the compressor 1 are generally transmitted to the outside of the compressor compartment through solid transmission and transmission in the form of air as a medium. When the compressor 1 is arranged in the sealed vacuum space 3, vibration and noise generated during operation of the compressor 1 cannot be conducted to the outside of the first shell 2 by taking air as a medium, or the vibration and noise transmitted to the outside of the first shell 2 by the air are less, so that the vibration and noise generated during operation of the compressor 1 by the compressor bin are reduced, and the user experience is improved.

On the other hand, the sealed vacuum space 3 reduces heat conduction of the compressor 1 while reducing vibration and noise of operation of the conductive compressor 1. The compressor 1 is arranged in the sealed vacuum space 3, so that heat generated during operation of the compressor is not easy to dissipate, the operation efficiency of the compressor 1 is possibly reduced, and even the compressor 1 is overheated and damaged when heat generation is serious. To solve this problem, the present utility model proposes to provide a heat transfer foot pad 4. When the compressor 1 is mounted in the first casing 2, the mounting column of the compressor 1 is necessarily in contact with the first casing 2. The heat transfer foot pad 4 is provided at the contact position of the compressor 1 and the first housing 2, and the heat transfer foot pad 4 is provided to make full use of the contact position, thereby further optimizing heat dissipation of the compressor 1. The heat transfer pad 4 may be made of a material having a high heat conductivity coefficient, such as aluminum, copper, etc., and may rapidly transfer heat of the mounting column of the compressor 1 to the first housing 2 and be emitted from the first housing 2. The heat transfer foot pad 4 can effectively transfer or radiate heat of the compressor 1 to the outside of the compressor bin, so that the heat radiation efficiency is improved, the temperature of the compressor 1 is maintained within a rated working temperature range, and the efficiency reduction or overheat damage of the compressor 1 is avoided.

In the present embodiment, one face of the heat transfer pad 4 is in contact with and abuts against the end face of the mounting post of the compressor 1, and the other face is in contact with and abuts against the inner wall of the bottom wall of the first casing 2, based on the fact that the compressor 1 is generally mounted on the upper side of the bottom wall of the first casing 2. In some cases, the compressor 1 is in an upside-down mounting state, the mounting column of the compressor 1 is located at the upper side of the body of the compressor 1, then the heat transfer foot pad 4 is also located at the upper side of the mounting column, and the other surface of the heat transfer foot pad 4 is in contact with and abuts against the inner wall of the top wall of the first housing 2.

In some embodiments of the compressor compartment for a refrigerator of the present utility model, as shown in fig. 1, the compressor compartment further includes a first heat dissipating bracket 8. The first heat dissipation fagging 8 level sets up, and first heat dissipation fagging 8 fixed connection is in first casing 2 downside, and is connected with the diapire heat of first casing 2.

In this embodiment, the first heat dissipation stay 8 is generally made of a material with high thermal conductivity, and heat generated during operation of the compressor 1 is conducted to the heat transfer foot pad 4 through the mounting post of the compressor 1, and is rapidly conducted to the bottom wall of the first housing 2 by the heat transfer foot pad 4. A small portion of the heat absorbed by the bottom wall of the first housing 2 is conducted to the side wall, top wall, etc. of the first housing 2 and dissipated through the side wall, top wall, etc. A large part of the heat absorbed by the bottom wall of the first housing 2 is conducted to the first heat dissipation stay plate 8, and rapidly dissipated by the first heat dissipation stay plate 8. By providing the first heat dissipation stay plate 8, the heat dissipation efficiency of the compressor 1 can be further improved.

In some embodiments of the compressor compartment for a refrigerator of the present utility model, the first housing 2 includes a first heat dissipating strut 8, the first heat dissipating strut 8 forming a bottom wall of the first housing 2, the first heat dissipating strut 8 having a higher thermal conductivity than the thermal conductivity of the side walls and top wall of the first housing 2.

In this embodiment, the bottom wall of the first housing 2 is the first heat dissipation supporting plate 8, and the heat generated during the operation of the compressor 1 is conducted to the heat transfer foot pad 4 through the mounting post of the compressor 1, is rapidly conducted to the first heat dissipation supporting plate 8 by the heat transfer foot pad 4, and is rapidly dissipated by the first heat dissipation supporting plate 8. By providing the first heat dissipation stay plate 8, the heat dissipation efficiency of the compressor 1 can be further improved.

In some embodiments of the compressor cartridge for a refrigerator of the present utility model, as shown in fig. 1, the first housing 2 has at least one air outlet 5.

The compressor compartment further comprises a vacuum pump 6, the vacuum pump 6 being in communication with the air outlet 5, the vacuum pump 6 being configured to draw air from within the sealed vacuum space 3 and to discharge it out of the first housing 2.

It should be noted that the first housing 2 may be provided with a fixed sealed vacuum space 3 to maintain a vacuum environment inside thereof, but this way requires a high requirement for the manufacturing process of the first housing 2. The first housing 2 may also be provided with an air outlet 5 through which air is drawn from the interior of the first housing 2 when the first housing 2 is manufactured, to form the sealed vacuum space 3. However, in this way, when the air outlet 5 is not tightly sealed, air leaks into the sealed vacuum space 3, which requires a user to inform maintenance personnel to perform secondary air suction, thereby increasing the failure rate and maintenance cost of the refrigerator.

In this embodiment, as shown in fig. 1, the compressor compartment is provided with at least one air outlet 5 in the first housing 2 and a vacuum pump 6, and the air outlet 5 is in communication with the vacuum pump. So configured, the vacuum pump 6 can perform a vacuuming operation on the sealed vacuum space 3, so that the sealed vacuum space 3 maintains a high vacuum state. At the same time, the vacuum pump 6 does not need too much power and does not increase too much power consumption. In addition, the vacuum pump 6 does not continuously work, and only when the vacuum degree in the sealed vacuum space 3 is low or is out of a preset range, intermittent work is needed so as to reduce the energy consumption of the whole refrigerator as much as possible.

In some embodiments of the compressor compartment for a refrigerator of the present utility model, as shown in fig. 2, a vacuum pump 6 is provided in the sealed vacuum space 3, and an exhaust port of the vacuum pump 6 communicates with the air outlet 5.

In this embodiment, as shown in fig. 2, the vacuum pump 6 is disposed in the sealed vacuum space 3, the air inlet of the vacuum pump 6 communicates with the sealed vacuum space 3, and the air outlet of the vacuum pump 6 communicates with the air outlet 5 of the first housing 2. When in operation, the vacuum pump 6 is started to pump the gas in the sealed vacuum space 3 and discharge the gas out of the first shell 2 through the gas outlet 5 of the first shell 2. The air pump is disposed in the sealed vacuum space 3 such that vibration and noise generated when the vacuum pump 6 is operated are not easily transmitted to the outside of the first housing 2. On the other hand, the whole structure of the compressor bin is compact, and the space occupation ratio of the internal equipment of the refrigerator to the whole refrigerator is reduced.

In some embodiments of the compressor compartment for a refrigerator of the present utility model, as shown in fig. 1, a vacuum pump 6 is provided outside the first housing 2, and an air inlet of the vacuum pump 6 communicates with an air outlet 5.

In this embodiment, the vacuum pump 6 is disposed outside the first housing 2, the air inlet of the vacuum pump 6 is communicated with the air outlet 5 of the sealed vacuum space 3, the air outlet of the vacuum pump 6 is located outside the first housing 2, and the vacuum pump 6 discharges the air in the sealed vacuum space 3 outside the first housing 2 through the air outlet 5. The vacuum pump 6 has a lower power and produces less vibration and noise during operation. The vacuum pump 6 is provided outside the first casing 2, so that the volume of the first casing 2 can be reduced, the vacuum degree of the sealed vacuum space 3 can be improved, or the high vacuum degree can be maintained relatively easily, compared with the case where the vacuum pump 6 is provided inside the first casing 2. Meanwhile, refrigerators of different specification models may need to be equipped with compressors 1 of different powers, while the vacuum pump 6 generally does not need to be replaced in model to match different compressors 1. By arranging the vacuum pump 6 outside the first housing 2, the first housing 2 and the compressor 1 in the first housing 2 can have different specifications and models without replacing the vacuum pump 6. The versatility of the vacuum pump 6 can be improved.

In actual use, when the vacuum degree in the sealed vacuum space 3 is low, it is optional to temporarily stop the operation of the compressor 1 and start the operation of the vacuum pump 6. Until the vacuum degree in the sealed vacuum space 3 is restored to be within the preset range, the operation of the vacuum pump 6 is stopped, and then the operation of the compressor 1 is resumed. In this way, the vibration and noise of the compressor 1 can be ensured not to be transmitted out of the compressor cabin as much as possible. The compressor 1 may be waited for to run normally, and after the preset refrigerating cycle is completed, the compressor 1 is stopped and then the vacuum pump 6 is started to run. Therefore, the vibration and noise of the compressor bin can be reduced as much as possible on the premise of ensuring the refrigeration and freezing quality of the refrigerator.

In some embodiments of the compressor compartment for a refrigerator of the present utility model, the compressor compartment further includes an air pressure sensor configured to detect air pressure of the sealed vacuum space 3 to control an operation state of the vacuum pump 6.

Air may enter the sealed vacuum space 3 to reduce the vacuum degree thereof, and the air may transmit vibration and noise of the compressor 1 to the outside of the first housing 2. In this embodiment, an air pressure sensor is provided to detect the air pressure of the sealed vacuum space 3. The air pressure sensor can be integrally arranged in the sealed vacuum space 3, and a cable of the air pressure sensor extends out of the sealed vacuum space 3 to be electrically connected with the refrigerator controller. The sensing part of the air pressure sensor can also be arranged in the sealed vacuum space 3, the electric control part of the air pressure sensor is arranged outside the sealed vacuum space 3, for example, the inside of a refrigerator controller, and the electric control part is electrically connected with the refrigerator controller. In this embodiment, when the air pressure is higher than the preset air pressure, it is indicated that the air in the sealed vacuum space 3 is more and needs to be exhausted. The air pressure sensor may be set to start operation in synchronization with the compressor 1 or to operate at preset timings or intervals, for example, at intervals of 1 hour or at every 1 hour of operation of the compressor 1 when the refrigerator is operated. Preferably, the air pressure sensor starts operation only when the compressor 1 stops operation, and then determines and controls the operation of the vacuum pump 6. Therefore, the vibration and noise of the compressor bin can be reduced as much as possible on the premise of ensuring the refrigeration and freezing quality of the refrigerator.

In some embodiments of the compressor cartridge for a refrigerator of the present utility model, as shown in fig. 1, the compressor cartridge further includes a second housing 7, the second housing 7 being disposed adjacent to the first housing 2 and sharing one housing wall.

The vacuum pump 6 is located within the second housing 7.

In this embodiment, the second housing 7 is used to accommodate the vacuum pump 6, which makes the compressor compartment modularized, facilitates installation in the refrigerator, and simplifies the assembly process. The second shell 7 is arranged adjacent to the first shell 2 and shares a shell wall, so that the material consumption of the second shell 7 can be reduced, and the heat transfer between the second shell 7 and the first shell 2 can be realized. When the refrigerator works normally, the heat generated by the compressor 1 is far greater than the heat generated by the vacuum pump 6, and when the compressor 1 works, the temperature of the first shell 2 is higher, and the temperature of the second shell 7 is relatively lower. In this way, the heat of the first casing 2 is quickly transferred to the second casing 7, and is dissipated through the second casing 7, which helps to improve the heat dissipation efficiency of the compressor 1.

In some embodiments of the compressor compartment for a refrigerator of the present utility model, as shown in fig. 1, the compressor compartment further includes a second heat dissipating bracket 9.

In this embodiment, the second heat dissipation supporting plate 9 is provided to further improve heat dissipation efficiency and reduce the operating temperature of the compressor 1. The first shell 2 transfers heat to the second shell 7, the second shell 7 dissipates part of the heat, the second shell 7 also transfers part of the heat to the second heat dissipation supporting plate 9, and the part of the heat is dissipated by the second heat dissipation supporting plate 9.

In some embodiments of the compressor compartment for a refrigerator of the present utility model, the first and second heat dissipating stay plates 8 and 9 are integrally formed to form the bottom wall of the first housing 2 and the bottom wall of the second housing 7.

In this embodiment, the first heat dissipation supporting plate 8 and the second heat dissipation supporting plate 9 are integrally formed, so that the first heat dissipation supporting plate 8 can rapidly conduct heat to the second heat dissipation supporting plate 9 and radiate the heat to the outside of the compressor bin.

In some embodiments of the compressor compartment for a refrigerator of the present utility model, the vacuum pump 6 is a variable frequency vacuum pump 6, and the operating state includes the magnitude of the operating power of the vacuum pump 6.

In this embodiment, when the vacuum degree is low as a result of detection by the air pressure sensor, the vacuum pump 6 can be controlled to start to operate, or the vacuum pump 6 can be controlled to operate with higher power, so as to extract air in the sealed vacuum space 3 as soon as possible, and improve the vacuum degree. When the vacuum degree is higher as a result of detection by the air pressure sensor, the vacuum pump 6 can be controlled to stop running, or the vacuum pump 6 can be controlled to run at lower power so as to stop or slow down the air pumping of the sealed vacuum space 3, and the energy consumption and noise of the vacuum pump 6 are reduced.

In some embodiments of the present utility model, the compressor compartment for a refrigerator, the compressor compartment further comprises a heat transfer plate. The heat transfer plate is fixedly connected to the shared shell wall of the second shell 7 and the first shell 2 and is positioned on the wall surface close to the compressor 1, or

In this embodiment, the second housing 7 not only can be connected to the first housing 2 to realize heat transfer, but also the heat transfer plate absorbs the heat radiation of the compressor 1 and transfers the heat of the heat transfer plate to the second housing 7, and the heat is dissipated through the second housing 7. The heat transfer plate is arranged, so that the heat dissipation efficiency can be further improved, and the working temperature of the compressor 1 can be reduced.
