Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and particularly to a refrigerator. Background Art

[0002] As one of the indispensable household appliances in modern families, the background art of refrigerators covers multiple fields, including refrigeration technology, material science, electronic technology, and intelligent technology, etc.

[0003] In the prior art, a refrigerator includes a box body, a compressor, an evaporator, and a condenser; the refrigerant output by the compressor enters the evaporator after releasing heat through the condenser, and the refrigerant absorbs the heat inside the box body in the evaporator and then returns to the compressor to achieve refrigeration inside the refrigerator. In addition, in some refrigerators, a dew removal pipe is provided between the evaporator and the condenser. When the temperature difference between the inside and outside of the refrigerator is large and the environmental humidity is relatively high, dew is likely to form around the refrigerator, forming water droplets. This not only affects the appearance but may also cause corrosion to the refrigerator. By flowing the refrigerant through the dew removal pipe, the temperature is raised, the temperature difference is reduced, and evaporation and condensation are reduced, achieving the dew removal effect.

[0004] However, when the humidity is very high, such as during the southward return of the warm current in the south, the condensation is severe, and the existing technology solutions cannot effectively achieve the dew removal effect. Therefore, in some cases, the high-temperature refrigerant output by the compressor is directly passed through the dew removal pipe to achieve dew removal. However, in this solution, the refrigerant can only pass through the dew removal pipe, and when the customer does not need dew removal, the dew removal function cannot be turned off. And the refrigerant passing through the dew removal pipe will cause factors such as an increase in the compressor pressure, resulting in higher power consumption. Summary of the Utility Model

[0005] The present utility model solves at least one of the technical problems in the related art to a certain extent.

[0006] For this reason, the present application aims to provide a refrigerator that can adjust the dew removal intensity according to requirements. And in the normal refrigeration state, the refrigerant can directly enter the evaporator through the branch pipe and then return, without passing through the dew removal pipe. Therefore, while ensuring the refrigeration capacity, energy loss is reduced, achieving the effect of high energy efficiency.

[0007] To achieve the above object, the present utility model provides a refrigerator, including:

[0008] A box body;

[0009] A compressor, the compressor is arranged inside the box body;

[0010] A condenser, the condenser is arranged inside the box body;

[0011] An evaporator, the evaporator is arranged inside the box body; the compressor, the condenser, and the evaporator are connected and used for flowing the refrigerant;

[0012] Dew removal pipe, the dew removal pipe is arranged between the condenser and the compressor;

[0013] Branch pipe, both ends of the branch pipe are respectively connected and communicated with both ends of the dew removal pipe;

[0014] First valve body, the first valve body is arranged on the branch pipe and is used to control the flow rate of the branch pipe;

[0015] Reversing valve, the reversing valve has a first state and a second state;

[0016] In the first state, the refrigerant output by the compressor passes through the condenser and then through the branch pipe, and / or, the dew removal pipe; and then returns to the compressor after passing through the evaporator;

[0017] In the second state, the refrigerant output by the compressor passes through the branch pipe, and / or, the dew removal pipe; and then returns to the compressor after passing through the condenser and the evaporator in sequence.

[0018] In the technical solution, in the normal refrigeration state, the first valve body makes the branch pipe communicate. At this time, the refrigerant will directly pass through the condenser and then enter the evaporator through the branch pipe and then return, and at this time the refrigerant does not pass through the dew removal pipe. In the normal dew removal state, the reversing valve enters the first state, the first valve body closes the branch pipe, the refrigerant enters the dew removal pipe after passing through the condenser, and returns after passing through the evaporator. When the humidity is high and large-scale dew removal is required, it enters the strong dew removal state. At this time, the reversing valve enters the second state, and the refrigerant directly enters the dew removal pipe and then enters the condenser and the evaporator in sequence and then returns. Because the refrigerant does not pass through the condenser for cooling, its temperature is higher and has a better dew removal effect. In this application, the dew removal intensity can be adjusted according to requirements. And in the normal refrigeration state, the refrigerant can directly enter the evaporator through the branch pipe and then return, without passing through the dew removal pipe. Therefore, while ensuring the refrigeration capacity, the energy loss is reduced, and the effect of high efficiency and energy saving is achieved.

[0019] In some embodiments of the present application, both ends of the dew removal pipe are respectively connected and communicated with a first main pipe and a second main pipe; the second main pipe is connected and communicated with the condenser;

[0020] Both ends of the branch pipe are respectively connected and communicated with the first main pipe and the second main pipe.

[0021] In the technical solution, through the design of the first main pipe and the second main pipe, the flow of the refrigerant is ensured, and it is ensured that the refrigerant can enter the corresponding dew removal pipe or branch pipe through the first main pipe or the second main pipe.

[0022] In some embodiments of the present application, the inner diameter of the branch pipe is not less than the inner diameters of the first main pipe and the second main pipe.

[0023] In the technical solution, this design helps to maintain the pressure stability of the refrigerant during the flow process, reduce the flow resistance caused by the change of pipe diameter, and improve the refrigeration efficiency. It reduces the excessive pressure at any end due to the too small inner diameter of the branch pipe, thereby reducing the refrigerant flow rate into the dew removal pipe and reducing the energy loss, ensuring the refrigeration effect.

[0024] In some embodiments of the present application, a second valve body is provided at any end of the dew removal pipe, and the second valve body is used to control the flow rate of the dew removal pipe.

[0025] In the technical solution, the refrigerant flow rate into the dew removal pipe is adjusted by the second valve body. When dew removal is not required, the dew removal pipe can be completely closed to further avoid flow loss.

[0026] In some embodiments of the present application, the reversing valve includes a first interface, a second interface, a third interface, and a fourth interface;

[0027] Among them, the output end of the compressor is communicated with the first interface; the end of the condenser far from the connection with the dew removal pipe is communicated with the second interface;

[0028] The input end of the evaporator is communicated with the third interface;

[0029] The first main pipe is communicated with the fourth interface.

[0030] In the technical solution, the control of the refrigerant flow direction is achieved by the on-off between the first interface, the second interface, the third interface, and the fourth interface on the reversing valve.

[0031] In some embodiments of the present application, when the reversing valve is in the first state, the first interface is communicated with the second interface; the third interface is communicated with the fourth interface;

[0032] When the reversing valve is in the second state, the first interface is communicated with the fourth interface; the second interface is communicated with the third interface.

[0033] In some embodiments of the present application, the first valve body is a flow valve, and the flow rate of the branch pipe is controlled by the flow valve, thereby controlling the refrigerant flow rate passing through the dew removal pipe.

[0034] In the technical solution, through the precise control of the flow valve, the refrigerant flow rate passing through the dew removal pipe can be adjusted, so as to realize the adjustment and control of the temperature of the dew removal pipe, ensuring the stability and precise control of the dew removal effect.

[0035] In some embodiments of the present application, a throttling member is provided at the input end of the evaporator, and the throttling member is used to reduce the refrigerant pressure.

[0036] In the technical solution, the refrigerant cooled by the condenser still has a relatively high temperature due to its high pressure. When passing through the throttling member, the pressure of the refrigerant is released, so that the temperature of the refrigerant drops instantaneously. The low-temperature and low-pressure refrigerant enters the evaporator to cool the inside of the refrigerator.

[0037] In some embodiments of the present application, an inner liner is provided on the box body, and the inner liner has an opening; the dew removal pipe is close to the opening of the inner liner.

[0038] In the technical solution, dew is removed at the opening of the inner liner to avoid excessive condensed water. And it avoids the situation that the condensed water freezes and causes the refrigerator door to be unable to open.

[0039] In addition, the present application also provides a refrigerator, which includes:

[0040] A box body;

[0041] A compressor, which is arranged inside the box body;

[0042] A condenser, which is arranged inside the box body;

[0043] An evaporator, which is arranged inside the box body; the compressor, the condenser and the evaporator are connected and used for flowing the refrigerant;

[0044] A dew removal pipe, which is arranged between the condenser and the compressor;

[0045] A branch pipe, the two ends of which are respectively connected and communicated with the two ends of the dew removal pipe;

[0046] A three-way valve, which is arranged at the connection of the branch pipe and the dew removal pipe, and the three-way valve is used to control the refrigerant to enter the dew removal pipe or the branch pipe;

[0047] A reversing valve, which has a first state and a second state;

[0048] In the first state, the refrigerant output by the compressor passes through the condenser and then through the branch pipe, and / or, the dew removal pipe; and then returns to the compressor after passing through the evaporator;

[0049] In the second state, the refrigerant output by the compressor passes through the branch pipe, and / or, the dew removal pipe; and then passes through the condenser and the evaporator in sequence and returns to the compressor.

[0050] In the technical solution, in the normal refrigeration state, the three-way valve connects the branch pipe. At this time, the refrigerant will directly pass through the condenser and then enter the evaporator through the branch pipe and then return, and at this time the refrigerant does not pass through the dew removal pipe. In the normal dew removal state, the reversing valve enters the first state, the three-way valve connects the dew removal pipe, the refrigerant passes through the condenser and then enters the dew removal pipe, and then returns after passing through the evaporator. When the humidity is high and large-scale dew removal is required, it enters the strong dew removal state. At this time, the reversing valve enters the second state, and the refrigerant directly enters the dew removal pipe and then enters the condenser and evaporator in sequence and then returns. Because the refrigerant does not pass through the condenser for cooling, its temperature is higher and it has a better dew removal effect. In the present application, the dew removal intensity can be adjusted according to requirements. And in the normal refrigeration state, the refrigerant can directly enter the evaporator through the branch pipe and then return, without passing through the dew removal pipe. Therefore, while ensuring the refrigeration capacity, the energy loss is reduced, and the effect of high efficiency and energy saving is achieved.

It reduces the excessive pressure at any end caused by the too small inner diameter of the branch pipe 600, thereby reducing the refrigerant flow rate entering the dew removal pipe 500, reducing the energy loss, and ensuring the refrigeration effect.

At this time, the reversing valve 700 enters the second state, the refrigerant directly enters the dew removal pipe 500 and then enters the condenser 200 and the evaporator 300 in sequence and then returns. Because the refrigerant does not pass through the condenser 200 for cooling, its temperature is higher and has a better dew removal effect. In the present application, the dew removal intensity can be adjusted according to requirements. And in the normal refrigeration state, the refrigerant can directly enter the evaporator 300 through the branch pipe 600 and then return, without passing through the dew removal pipe 500. Therefore, while ensuring the refrigeration capacity, the energy loss is reduced, and the effect of high efficiency and energy saving is achieved.

[0137] In some embodiments, on the basis of providing the three-way valve 110, a second valve body 900 is further provided. The second valve body 900 is arranged on the dew removal pipe 500, and the second valve body 900 is used to control the flow rate of the refrigerant passing through the dew removal pipe 500, so as to achieve precise control of the temperature of the dew removal pipe 500.

[0138] In some embodiments, one end of the dew removal pipe 500 is connected and communicated with a first main pipe.

[0139] In some embodiments, the end of the dew removal pipe 500 far from the first main pipe is connected and communicated with a second main pipe.

[0140] In some embodiments, the second main pipe is connected and communicated with the condenser 200.

[0141] In some embodiments, both ends of the branch pipe 600 are respectively connected and communicated with the first main pipe and the second main pipe.

[0142] In some embodiments, the three-way valve 110 can be arranged at the connection between the first main pipe and the branch pipe 600.

[0143] In some embodiments, the three-way valve 110 can only connect the first main pipe and the dew removal pipe 500, that is, the refrigerant can only enter the dew removal pipe 500.

[0144] In some embodiments, the three-way valve 110 can only connect the first main pipe and the branch pipe 600, that is, the refrigerant can only enter the branch pipe 600.

[0145] In some embodiments, the three-way valve 110 can be arranged at the connection between the second main pipe and the branch pipe 600.

[0146] In some embodiments, the three-way valve 110 can only connect the second main pipe and the dew removal pipe 500, that is, the refrigerant can only enter the dew removal pipe 500.

[0147] In some embodiments, the three-way valve 110 can only connect the second main pipe and the branch pipe 600, that is, the refrigerant can only enter the branch pipe 600.

[0148] In some embodiments, the three-way valve 110 can connect all three ports at the same time, that is, the refrigerant can pass through the dew removal pipe 500 and the branch pipe 600 at the same time. Part of the refrigerant enters the dew removal pipe 500, and part of the refrigerant directly enters the evaporator 300 through the branch pipe 600, reducing energy loss while ensuring the dew removal effect.

[0149] In some embodiments, in the normal refrigeration state, the refrigerant does not need to enter the dew removal pipe 500. At this time, the first valve body 800 is opened to form a passage for the branch pipe 600. In this state, the reversing valve 700 can be in the first state or the second state.

[0150] In some embodiments, in the normal refrigeration state, while the first valve body 800 is opened, the second valve body 900 closes the dew removal pipe 500.

[0151] In some embodiments, the strong dew removal state can be selected to be turned on when the humidity is greater than or equal to 90%.

[0152] In some embodiments, a control board can be provided in the present application, and the control board is electrically connected to the reversing valve 700.

[0153] In some embodiments, the first valve body 800 can be electrically connected to the control board.

[0154] In some embodiments, the second valve body 900 can be electrically connected to the control board.

[0155] In some embodiments, the three-way valve 110 can be electrically connected to the control board.

[0156] In some embodiments, the refrigerator can include a humidity sensor.

[0157] In some embodiments, the humidity sensor can be electrically connected to the control board.

[0158] Through the above solution, through the calculation and analysis of multiple different working conditions, the heat transfer coefficient of the dew removal pipe 500 to the inside of the refrigerator is basically about 1.1 W / (m2·K). Taking the refrigerator 331 under test as an example, the total length of the dew removal pipe 500 is 2.6 m. At 32 °C, through calculation, the heat transfer amount of the dew removal pipe 500 to the inside of the box is 2.16 W, accounting for about 6.5% of the total heat load of the box. If the refrigerant flow rate in the dew removal pipe 500 is adjusted to 0 under low ambient humidity, the power consumption can be saved by 6.5%. It can be seen from this that the present application has a strong energy-saving effect.

[0159] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
