Description

refrigerator

The present invention relates to a refrigerator, in particular to a refrigerator with multiple doors.

The existing refrigerator includes two refrigerated spaces with different temperatures (e.g., a freezer and a refrigerator), and the air cooled by a heat exchange device is blown to the refrigerated spaces with different temperatures through a cold air passage, and the higher temperature gas in the original refrigerated space is guided back to the heat exchange device for cooling through the independent return air path of each refrigerated space, so that the refrigerated spaces with different temperatures are maintained at different low temperature states. However, the outlets of the return air paths converge near the heat exchange device, so that the gas in the refrigerated space with a higher temperature flows into the refrigerated space with a lower temperature through the outlets of the return air paths, causing the temperature of the refrigerated space with a lower temperature to rise. The compressor needs to be started again to return the temperature of the refrigerated space with a lower temperature to the set value, resulting in excessive power consumption of existing refrigerators.

Therefore, the purpose of the present invention is to provide a refrigerator that can solve the above-mentioned problems.

Therefore, the refrigerator of the present invention comprises a refrigerator shell, a freezing chamber body, a refrigerating chamber body, a refrigerating chamber return air passage and a baffle.

The refrigerator shell defines a refrigeration space.

The freezing chamber box body is arranged in the refrigerator shell and defines a freezing space. The freezing space has a freezing chamber return air inlet structure connected to the refrigeration space.

The refrigerating chamber box body is arranged in the refrigerator shell body and defines a refrigerating space separated from the freezing space.

The refrigerating chamber return air passage is arranged in the refrigerator shell and connected to the refrigerating space, and comprises a return air passage outlet connected to the refrigerating space and located at the same side of the refrigerating space as the refrigerating chamber return air inlet structure.

The baffle is arranged in the refrigeration space and between the return air inlet structure of the refrigerating chamber and the return air passage outlet. The baffle is used to block the gas from flowing from the return air passage outlet to the return air inlet structure of the refrigerating chamber.

In some embodiments, the return air duct outlet is located below the return air inlet structure of the refrigerating chamber. The baffle extends transversely above the return air duct outlet to block the gas from flowing from the return air duct outlet to the return air inlet structure of the refrigerating chamber.

In some embodiments, the refrigerator further includes a heat exchange device and a fan. The heat exchange device is installed in the refrigeration space and is used to allow the gas to exchange heat and cold. The fan is installed in the refrigeration space and is located above the heat exchange device. The return air inlet structure of the freezing chamber is connected to the bottom of the refrigeration space. The return air duct outlet is connected to the bottom of the refrigeration space and is located below the return air inlet structure of the freezing chamber. The fan is used to suck the gas from the return air duct outlet upward, so that the gas circulates in the refrigeration space and is blocked by the baffle and cannot flow to the return air inlet structure of the freezing chamber, and can pass through the heat exchange device.

In some embodiments, the refrigerating chamber body is located in front of the heat exchange device, and the refrigerating chamber return air inlet structure is aligned backward with the heat exchange device. The refrigerator also includes a partition. The partition is arranged in the refrigerating space and is located between the refrigerating chamber return air inlet structure and the heat exchange device. The partition divides the refrigerating space into an extended channel portion adjacent to the refrigerating chamber return air inlet structure and a refrigerating channel portion for the heat exchange device to be arranged. The fan is used to suck the gas from the refrigerating chamber return air inlet structure through the extended channel portion to the refrigerating channel portion, so that the gas can pass through the heat exchange device.

In some embodiments, the opening of the extended channel portion is downward. The baffle extends backward from the rear side of the top edge of the refrigerating chamber return air channel to shield a part of the opening of the extended channel portion.

The effect of the present invention is that by setting the baffle, the gas in the return air passage of the refrigerating chamber can be blocked from flowing into the refrigerating space, so that the temperature of the refrigerating space is not disturbed and remains unchanged, thereby reducing the operating frequency of the air conditioner compressor to achieve the effect of energy saving.

Referring to FIG. 1 , an embodiment of the refrigerator of the present invention is shown. First, the directional terms used in the description herein are defined. In FIG. 1 , the left side of the refrigerator is defined as the “front side”, and the right side of the refrigerator is defined as the “rear side”. The refrigerator can be used for refrigerating or freezing food or other items, and is provided with a door and components such as a compressor and a control circuit module that are not shown in the figure, and includes a refrigerator housing 1 that opens forward, and a heat exchange device 2, a fan 3, a freezing chamber body 4, a refrigerating chamber body 5, a refrigerating chamber return air duct 6, a baffle 7, and a partition 8 arranged in the refrigerator housing 1.

Referring to FIG. 1 , the inner side of the refrigerator shell 1 and the rear side of the refrigerating chamber body 4 define a refrigerating space 11 for the heat exchange device 2 and the fan 3 to be arranged, but the refrigerating space 11 may also be defined by the inner side of the refrigerator shell 1 and other components in the refrigerator shell 1, and is not limited to the above description. The heat exchange device 2 can be driven by the compressor to perform cold and heat exchange. The heat exchange device 2 is installed in the refrigerating space 11 and is used to allow the gas passing through the heat exchange device 2 to perform cold and heat exchange to achieve the effect of cooling the gas. The fan 3 is installed in the refrigerating space 11 and is located on the side of the heat exchange device 2 away from the refrigerating chamber body 5. The fan 3 is used to drive the air flow in the refrigeration space 11, so that the air passes through the heat exchange device 2, and blows the air that has passed through the heat exchange device 2 and has been cooled into the refrigeration chamber body 4. In this embodiment, the fan 3 is located above the heat exchange device 2 and is aligned with the top of the refrigeration chamber body 4, so that the cold air blown into the refrigeration chamber body 4 by the fan 3 flows from top to bottom according to the convection mechanism.

Referring to FIG. 1 , the refrigerating chamber housing 4 is, for example, a cube but not limited thereto, and defines a refrigerating space 41 that opens forward. The refrigerating space 41 is provided with an air inlet that is not shown in the figure and is aligned with the fan 3, and has a refrigerating chamber return air inlet structure 411 formed at the rear side of the refrigerating chamber housing 4 and connected to the refrigerating space 11. The refrigerating chamber return air inlet structure 411 is located at the bottom of the refrigerating chamber housing 4 and is aligned with the heat exchange device 2, so that the gas in the refrigerating space 41 can be guided to the heat exchange device 2 through the refrigerating space 11. In this embodiment, the height of the refrigeration chamber return air inlet structure 411 is lower than the height of the air inlet of the refrigeration space 41, so that the cooling circulation in the refrigeration space 41 flows from top to bottom. In addition, the refrigeration chamber return air inlet structure 411 is exemplified by multiple slits, but the refrigeration chamber return air inlet structure 411 can also be a single hole, depending on actual needs.

Referring to FIG. 1 , the refrigerating chamber body 5 is, for example, a rectangular parallelepiped but not limited thereto and is installed below the freezing chamber body 4 and defines a refrigerating space 51 which opens forward and is separated from the freezing space 41. The temperature in the refrigerating space 51 is higher than that in the freezing space 41. The refrigerating chamber return air passage 6 is connected to the refrigerating space 51 and includes a return air passage outlet 61 connected to the refrigerating space 11. The return air passage outlet 61 is located below the refrigerating chamber return air inlet structure 411 and is located on the same side of the refrigerating space 11 as the refrigerating chamber return air inlet structure 411. In other words, the return air passage outlet 61 and the refrigerating chamber return air inlet structure 411 are both facing backward to guide the gas to the heat exchange device 2. In this embodiment, the refrigerating chamber return air passage 6 is in the shape of a long strip, and the refrigerating chamber return air passage 6 extends from the front side of the top of the refrigerating chamber body 5 to the rear and upward to the bottom of the refrigerating space 11, so that the gas in the refrigerating space 51 that is heated by the outside world can flow back from bottom to top to the refrigerating space 11. However, the refrigerating chamber return air passage 6 can also be just an opening (i.e., the return air passage outlet 61) formed on one side wall of the refrigerating chamber body 5 and connected to the refrigerating space 11, and is not limited to a specific form.

Referring to FIG. 1 and FIG. 2 , the baffle 7 is rectangular but not limited thereto, and is disposed in the refrigeration space 11 and between the return air outlet structure 411 of the refrigerating chamber and the return air duct outlet 61. The baffle 7 is used to block the gas from flowing from the return air duct outlet 61 to the return air outlet structure 411 of the refrigerating chamber. More specifically, the baffle 7 extends rearwardly and laterally from the rear side of the top edge of the return air duct 6 of the refrigerating chamber, and can effectively block the gas from flowing from the return air duct outlet 61 to the return air outlet structure 411 of the refrigerating chamber. However, the baffle 7 can also extend backward from a portion of the refrigerator housing 1 located above the return air duct 6 of the refrigerating chamber, or extend backward from the bottom edge of the refrigerating chamber body 4, depending on actual needs.

Referring to Fig. 1 and Fig. 2, the partition 8 is disposed in the refrigeration space 11 and is located between the refrigeration chamber return air outlet structure 411 and the heat exchange device 2. More specifically, the partition 8 is in an inverted L-shape, and one side of the partition 8 is connected to the rear side of the refrigeration chamber body 4 and is located above the refrigeration chamber return air outlet structure 411, while the other side of the partition 8 stands vertically between the refrigeration chamber return air outlet structure 411 and the heat exchange device 2, so as to divide the refrigeration space 11 into an extended channel portion 111 adjacent to the refrigeration chamber return air outlet structure 411 and opening downward, and a refrigeration channel portion 112 for the heat exchange device 2 to be disposed. In this embodiment, the height of the bottom edge of the partition 8 is lower than the height of the refrigerating chamber return air inlet structure 411, so that the gas from the refrigerating chamber return air inlet structure 411 is restricted by the partition 8 and cannot be directly blown to the heat exchange device 2, and the extended channel portion 111 generates a downward airflow, thereby blocking the gas from flowing upward from the return air channel outlet 61 to the refrigerating chamber return air inlet structure 411. In addition, the front side portion of the opening of the extended channel portion 111 is shielded by the baffle 7 to prevent the gas from the return air channel outlet 61 from flowing to the refrigerating chamber return air inlet structure 411.

Referring to FIG. 1 and FIG. 2 , the cooling cycle of the refrigerator is described in detail below. First, the fan 3 is driven by the control circuit module to produce an exhaust effect, driving the gas in the refrigeration space 11 to flow from bottom to top through the heat exchange device 2 to perform a heat exchange of the gas and reduce the temperature of the gas. Then, the fan 3 blows the cooled gas from the back to the front to the freezing space 41, and then allows the low-temperature gas to flow from the freezing space 41 to the refrigerated space 51, or the fan 3 blows the cooled gas to the refrigerated space 51 through other cooling channels not shown in the figure, so that the temperature of the freezing space 41 and the refrigerated space 51 is maintained at a set value. Then, through the heat convection mechanism and the continuous air extraction of the fan 3, the higher temperature gas in the refrigerated space 51 will be guided by the refrigerating chamber return air channel 6 and flow to the refrigerating space 11 through the return air channel outlet 61. In addition, the gas from the return air channel outlet 61 will be blocked and guided by the baffle 7 located above and extending laterally, and flow backward to the refrigerating channel portion 112 of the refrigerating space 11. At the same time, the higher temperature gas in the freezing space 41 will also be affected by the continuous air extraction of the fan 3, and will flow out from the freezing chamber return air port structure 411, and will be guided by the extended channel portion 111 to flow to the refrigerating channel portion 112 of the refrigerating space 11. Finally, the gas from the return air duct outlet 61 and guided by the baffle 7 and the gas from the freezer chamber return air inlet structure 411 and guided by the extended channel portion 111 will both flow toward the refrigeration channel portion 112 and can be driven by the fan 3 again to pass through the heat exchange device 2 to complete the cooling cycle path of the refrigerator.

In summary, by providing the baffle 7, the gas in the cold room return air passage 6 can be blocked from flowing into the refrigerating space 41, so that the temperature of the refrigerating space 41 is not disturbed and remains unchanged, thereby reducing the operating frequency of the air-conditioning compressor to achieve energy saving effect, and thus the purpose of the present invention can be achieved.

However, the above is only an embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.
