Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and more specifically to a refrigerator. Background Art

[0002] At present, refrigerators on the market often use fans to drive airflow to circulate between the refrigeration chamber and the cold source to achieve rapid refrigeration in the refrigeration chamber. For example, Chinese patent number CN221114858U discloses a cosmetic sample refrigerator, which can conveniently place frozen ice bags by setting a placement bucket, a first fan and a barrier, and then use multiple first fans to increase the circulation effect of the airflow, thereby quickly reducing the temperature inside the refrigerator body. Although this prior art has a good refrigeration effect, the fan inside the refrigerator is still running at high speed after the door is opened. The high-speed fan will generate a lot of noise, resulting in a poor user experience. At the same time, when the refrigerator door is opened, the high-speed fan will also blow away the original cold air inside the refrigerator, which will consume the coldness inside the product and cause unnecessary waste. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a noise-reducing and energy-saving refrigerator, which can reduce the noise of products and save the power consumption of products.

[0005] The technical solution provides a refrigerator that can detect the opening of the door through an induction door opening device. When the door is opened, the cooling fan inside the box will stop running and no longer generate noise.

Therefore, the refrigerator can reduce the noise of the product while also saving the power consumption of the product, making it more energy-saving and environmentally friendly.

[0006] In a preferred technical solution, when the door opening sensing device detects that the door body has been in the open state for a period of time exceeding a preset period, the control circuit board controls the cold fan to start rotating again to prevent the cold fan from stopping rotating for too long, causing excessive frost on the cooling components and jamming the fan.

[0008] In a preferred technical solution, there are two refrigeration cavities, and the two refrigeration cavities are respectively located at the upper and lower parts of the back side of the refrigeration cavity, so as to more fully cool the refrigeration cavity.

[0009] In a preferred technical solution, the cold transfer component includes a cold transfer aluminum plate and a cold transfer aluminum block.

The cold transfer aluminum plate has a larger area and can better cool the air entering the refrigeration chamber, thereby ensuring the refrigeration efficiency.

[0010] In a preferred technical solution, the cold source component is a semiconductor refrigeration plate, and the cold transfer aluminum block is in contact with and connected to the cold end of the semiconductor refrigeration plate to conduct cold energy.

[0011] In a preferred technical solution, a heat dissipation cavity is provided between the outer shell and the inner shell behind the refrigeration cavity, and the heat dissipation cavity is separated from the refrigeration cavity and connected to the outside; a heat dissipation component is provided in the heat dissipation cavity, and the heat dissipation component is used to drive the air in the heat dissipation cavity to circulate with the external air, so as to achieve rapid heat dissipation in the heat dissipation cavity.

In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0023] Reference Figure 1-3A refrigerator according to an embodiment of the present invention is described.

[0024] In one embodiment, Figure 1-2 As shown, a refrigerator comprises a box body 1, a door body 2 and a control circuit board 3. The box body 1 comprises an outer shell and an inner liner arranged in the outer shell. The inner liner forms a refrigeration chamber 12. A refrigeration chamber connected to the refrigeration chamber 12 is arranged between the outer shell and the inner liner. A cold fan 13, a cold transfer component 14 and a cold source assembly 15 are arranged in sequence in the refrigeration chamber from the inner liner to the outer shell; wherein the cold fan 13, the cold transfer component 14 and the cold source assembly 15 together constitute a refrigeration assembly for cooling the refrigeration chamber 12. As an implementation method of this embodiment, the refrigeration chamber is located between the rear side plate of the inner liner and the rear side plate of the outer shell.

[0025] A magnet 21 is provided in the middle of one side of the door body 2 for opening and closing, and an induction door opening device 11 is provided at a position of the box body 1 corresponding to the magnet 21 of the door body 2; the control circuit board 3 is respectively connected to the induction door opening device 11 and the cooling fan 13, and controls the cooling fan 13 to stop rotating when the induction door opening device 11 detects that the door body 2 is opened. The induction door opening device 11 can adopt an existing door magnetic sensor.

[0026] On the one hand, the refrigerator can realize the door opening noise reduction function. After the door body 2 is opened, the door opening induction device 11 does not sense the magnet 21, and will send a door opening signal to the control circuit board 3. After receiving the door opening signal, the control circuit board 3 sets the voltage output to the cooling fan 13 to 0V, and the cooling fan 13 stops working, and the cooling fan 13 inside the box body 1 will not generate noise. On the other hand, the refrigerator can realize the door opening energy saving function.

[0027] When the door of the refrigerator is opened, the cooling fan 13 stops running, and the cold air in the refrigeration chamber 12 stops flowing. The cold air is in a static state inside the box body 1, so most of the cold air remains inside the box body 1. When the door is closed, the refrigerator only needs a small amount of cooling to make the refrigerator reach the required temperature point again and enter the insulation state. Therefore, the cooling fan 13 stops working after the door is opened, which not only reduces the power consumption of the fan itself, but also locks the cold air in the box body 1, achieving a double energy-saving effect.

[0028] In this embodiment, the above-mentioned refrigerator can detect the opening of the door body 2 through the induction door opening device 11. When the door body 2 is opened, the cold fan 13 inside the box body 1 will stop running and no longer generate noise; at the same time, since the cold fan 13 stops working, the cold air inside the box body 1 will not be blown out, which can reduce the power consumption of the product.

[0029] In this embodiment, when the door opening sensing device 11 detects that the door body 2 has been in the open state for a period exceeding a preset period, the control circuit board 3 controls the cold fan 13 to start rotating again to prevent the cold fan 13 from stopping rotating for too long, causing excessive frost on the cold transfer component 14 and jamming the fan.

[0030] The above-mentioned refrigerator can realize the function of preventing excessive frost in the refrigerator by opening the door. The preset time length may be in the range of 1 to 10 minutes, for example, 5 minutes.

[0031] When implementing it, Figure 2 From the air flow direction indicated by the middle arrow, it can be seen that the cold source component 15 is at the back of the box body 1. When the cold source component 15 is powered on, it generates cold energy and conducts the cold energy to the cold transfer component 14. The cold fan 13 blows the cold energy directly toward the cold transfer component 14, blowing the cold energy to the refrigeration chamber 12 inside the box body 1, thereby reducing the temperature inside the refrigeration chamber 12.

[0032] After the refrigerator door is opened, in order to ensure the stability of the temperature inside the box 1, the cold source component 15 needs to continue cooling, but at this time the cold fan 13 stops working and cannot blow the cold energy generated by the cold source component 15 into the box 1, resulting in more and more cold energy on the cold transmission component 14. When the cold energy accumulates to a certain amount, the cold transmission component 14 will cool down to below zero degrees. At this time, the cold transmission component 14 will frost. If there is too much frost, there is a risk of the cold fan 13 being stuck, affecting the product function. In other words, the cold fan 13 cannot stop working for a long time, and the cold transmission component 14 will be frosted and stuck. Therefore, the control circuit board 3 can be set to open the door for more than a preset time, for example, after the door is opened for 5 minutes, if the door body 2 has not been closed, the cold fan 13 is automatically turned on to blow away the cold energy on the cold source component 15 and the cold transmission component 14 to prevent the fan from being stuck by frost.

[0033] In this embodiment, an air outlet and an air return port are provided on the inner tank, and the refrigeration chamber is connected with the cold storage chamber 12 through the air outlet and the return port, and a cold fan 13 is installed corresponding to the air outlet so as to draw the air in the cold storage chamber 12 from the air outlet into the refrigeration chamber for cooling, and then blow the cooled air back into the cold storage chamber 12 from the return port to realize cooling of the cold storage chamber 12.

[0034] As an implementation of the above embodiment, the number of refrigeration cavities is two, and the two refrigeration cavities are respectively located at the upper and lower parts of the back side of the refrigeration cavity 12, so as to more fully cool the refrigeration cavity 12.

[0035] In specific implementation, the two refrigeration chambers can be located at the left and right parts of the back of the refrigeration chamber 12 respectively. More or fewer refrigeration chambers can be designed according to actual needs, and the refrigeration chamber can also be arranged on the side of the refrigeration chamber 12.

[0036] In this embodiment, if Figure 3 Shown Figure 2 The enlarged structure of part A, the cooling component 14 includes a cooling aluminum plate 141 and a cooling aluminum block 142, the front of the cooling aluminum plate 141 is installed corresponding to the cooling fan 13, the back of the cooling aluminum plate 141 is in contact with and connected to the cooling aluminum block 142, and the cooling aluminum block 142 is in contact with and connected to the cold source component 15.

[0037] Among them, the size of the cold transfer aluminum block 142 can be consistent with the cold source component 15 so as to completely conduct the cold. The cold transfer aluminum plate 141 has a larger area and can better cool the air entering the refrigeration chamber to ensure the refrigeration efficiency.

[0038] In specific implementation, the cold energy of the cold source assembly 15 is transferred to the cold transfer aluminum plate 141 through the cold transfer aluminum block 142, and the cold fan 13 draws the air of the refrigerating chamber 12 from the air outlet and blows it to the cold transfer aluminum plate 141. The air becomes cold after passing through the cold transfer aluminum plate 141, and then returns to the refrigerating chamber 12 through the return air port. In the above process, the cold fan 13 drives the air flow to circulate in the refrigerating chamber 12 and the refrigerating chamber, so as to realize rapid refrigeration in the refrigerating chamber 12.

[0039] As an implementation of the above embodiment, the cold source component 15 is a semiconductor refrigeration plate, and the cold transfer aluminum block 142 is in contact with the cold end of the semiconductor refrigeration plate to transfer the cold from the cold end of the semiconductor refrigeration plate to the cold transfer aluminum plate 141.

[0040] In this embodiment, if Figure 3 As shown, a heat dissipation cavity is provided behind the refrigeration cavity between the outer shell and the inner tank, and the heat dissipation cavity is separated from the refrigeration cavity and communicated with the outside; a heat dissipation component is provided in the heat dissipation cavity.

[0041] The heat dissipation assembly may include a heat dissipation aluminum plate 16 and a heat dissipation fan 17 arranged in sequence from the inner tank to the outer shell, the heat dissipation fan 17 is installed corresponding to the air outlet of the outer shell, and the heat dissipation aluminum plate 16 is in contact with the hot end of the semiconductor cooling plate. The heat dissipation assembly can drive the air in the heat dissipation cavity to circulate with the external air, realize rapid heat dissipation in the heat dissipation cavity, thereby improving the heat dissipation efficiency of the semiconductor cooling plate and further ensuring the cooling efficiency.

[0042] In this embodiment, the control circuit board 3 is installed at the bottom of the rear side plate of the housing. In specific implementation, the control circuit board 3 can be arranged in the box body and installed at the concave position at the bottom of the rear side plate of the housing, which is convenient for installation and maintenance.
