The refrigerator 100 includes a compressor, a condenser, an expansion valve, and an evaporator 51, and a refrigeration cycle is performed through the compressor, the condenser, the expansion valve, and the evaporator 51. The refrigerating cycle includes a compression process, a condensation process, an expansion process, and an evaporation process, and provides cold or heat to the storage space 11 through heat absorption and release processes of the refrigerant, thereby achieving temperature regulation of the storage space 11.

The compressor compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas, and the discharged refrigerant gas flows into the condenser. The condenser condenses the compressed high-temperature and high-pressure gaseous refrigerant into a liquid refrigerant, and heat is released to the surrounding environment through the condensation process.

The liquid refrigerant flowing out of the condenser enters an expansion valve, and the expansion valve expands the liquid refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid refrigerant. The low-pressure liquid refrigerant flowing out of the expansion valve enters the evaporator 51, and when the liquid refrigerant flows through the evaporator 51, the absorbed heat evaporates into a low-temperature low-pressure refrigerant gas, and the refrigerant gas in a low-temperature low-pressure state is returned to the compressor. The evaporator 51 may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. In the whole cycle, heat of the storage space 11 in the refrigerator 100 is transferred to the outside of the refrigerator 100 through the refrigerating cycle, so that the storage space 11 in the refrigerator 100 can be kept at a temperature lower than the indoor environment, and the objects in the storage space 11 can be refrigerated or frozen, so that the storage time of the objects in the refrigerator 100 is prolonged, and the requirements of users on refrigeration are met.

According to the refrigerator 100 of the present utility model, the storage space 11 is partitioned into the freezing chamber 31 and the refrigerating chamber 32, and generally, the temperature of the freezing chamber 31 is below-18 degrees celsius, the temperature of the refrigerating chamber 32 is 0-10 degrees celsius, and in actual production, the temperatures of the freezing chamber 31 and the refrigerating chamber 32 may be set according to the needs of users.

The freezing chamber 31 and the refrigerating chamber 32 of the present utility model are arranged up and down, and the refrigerating chamber 32 and the freezing chamber 31 may be arranged up and down in a specific manner according to actual customer demands, i.e., the refrigerating chamber 32 may be arranged above the freezing chamber 31, and in other embodiments, the freezing chamber 31 may be arranged above the refrigerating chamber 32.

In the present utility model, the freezing chamber 31 is disposed at one side of the storage space 11 near the top plate 12, the refrigerating chamber 32 is disposed at one side of the freezing chamber 31 near the base 13, the refrigerating chamber 32 is disposed below the freezing chamber 31, and the volume of the refrigerating chamber 32 is larger than the volume of the freezing chamber 31.

The refrigerator 100 further comprises a water box 6, the water box 6 is arranged on one side of the evaporator 51 close to the base 13, the water box 6 is used for receiving condensed water on the surface of the evaporator 51, a water outlet 62 and a ventilation opening 61 are arranged on the side wall or the bottom of the water box 6, the water outlet 62 is arranged close to the bottom of the water box 6, the ventilation opening 61 is arranged on one side of the water outlet 62 close to the top plate 12, namely the ventilation opening 61 is arranged above the water outlet 62. Wherein, the condensed water in the water box 6 flows out from the water outlet 62 near the bottom, which is beneficial to the outflow of the condensed water from the water outlet 62 at a lower position. The water box 6 exchanges gas with the main drainage pipe 7 through the ventilation port 61, because the ventilation port 61 is positioned above the water outlet 62, the density of the gas is less than that of the water, the gas is positioned above the condensed water in the water box 6, and the ventilation port 61 is positioned above the water outlet 62, so that the ventilation port 61 is correspondingly arranged above the gas of the condensed water in the water box 6, thereby being beneficial to the exchange of the gas.

The drain main pipe 7 communicates with the drain port 62 and the air vent 61, and extends in the height direction of the tank 1 between the top plate 12 and the base 13, and the drain main pipe 7 is used for draining condensed water in the water box 6, and condensed water in the water box 6 enters the drain main pipe 7 through the drain port 62 and is drained. The vent main pipe communicates with the ventilation port 61 so that bubbles in the vent main pipe can flow back into the water tank 6 through the ventilation port 61, instead of flowing back into the water tank 6 through the water drain port 62.

The refrigerator 100 further includes a water box joint 8, the water box joint 8 being connected between the drain main pipe 7 and the water box 6 so that the water box 6 and the drain main pipe 7 communicate. The water box joint 8 comprises a drainage connecting pipe 81 and a ventilation pipe 82, wherein the drainage connecting pipe 81 is used for draining condensed water in the water box 6, and the ventilation pipe 82 is used for draining bubbles which flow back to the water box 6 in the exhaust main pipe so that the exhaust main pipe is communicated with a gas space in the water box 6.

One end of the ventilation pipe 82 is connected with the ventilation port 61, and the other end is connected to the pipe wall of the drainage connecting pipe 81, which is close to the top plate 12, so that the ventilation pipe 82 is communicated with the drainage connecting pipe, when bubbles in the drainage main pipe 7 flow back to the water box 6, the bubbles flow towards the direction of the top plate 12, and flow through the drainage main pipe 7, the drainage connecting pipe 81 and the ventilation pipe 82 in sequence and then enter the water box 6.

Specifically, when the bubbles flow back into the drain connection pipe 81, since the density of the bubbles is smaller than that of water, the bubbles can move upward all the time, can enter the ventilation pipe 82 through the upper pipe wall of the drain connection pipe 81, and enter the space above the condensed water in the water box 6 through the ventilation pipe 82 instead of entering the water outlet 62 in the water box 6 through the drain connection pipe 81, the bubbles in the utility model can directly enter the gas space above the condensed water through the ventilation pipe 82 without generating the noise of the bubble flow back because the bubbles flow together with the liquid in the drain connection pipe 81 and the water outlet 62.

Since the lower end of the main drain pipe 7 is in contact with the total water receiving tray 92, the lower end of the main drain pipe 7 is in contact with air, and the main drain pipe 7 generally has some bubbles, the bubbles tend to flow back upward to the upper end of the main drain pipe 7 because the density of the bubbles is smaller than that of the condensed water. When the air bubbles in the main drain pipe 7 flow back to the water box 6, the air bubbles flow in the direction of the top plate 12, and the air bubbles flow from the main drain pipe 7 to the upper end of the main drain pipe 7, and the upper end of the main drain pipe 7; the water box joint 8 is connected, because the drainage connecting pipe 81 is located below the ventilation pipe 82, air bubbles flow into the drainage connecting pipe 81 firstly, until the air bubbles flow to the upper pipe wall of the drainage connecting pipe 81, because the ventilation pipe 82 is communicated with the upper pipe wall of the drainage connecting pipe 81, the air bubbles can flow into the ventilation pipe 82 through the opening of the upper pipe wall of the drainage connecting pipe 81, the ventilation pipe 82 is communicated with the ventilation port 61 of the water box 6, and because the ventilation port 61 is located above the water outlet 62, the air bubbles in the ventilation pipe 82 finally flow into the air space above condensed water in the water box 6 through the ventilation port 61 of the water box 6, and when the air bubbles flow back to the water box 6, the air bubbles enter the water box 6 through the ventilation port 61, so that backflow noise can not be generated.

In the prior art, only the water box 6 is provided with the water outlet 62, the water outlet 62 is used for discharging condensed water, the condensed water in the water box 6 directly flows into the main water drainage pipe 7 through the water outlet 62, the prior art is not provided with the ventilation port 61, when bubbles in the main water drainage pipe 7 flow back, the bubbles can only flow into the water box 6 together with the condensed water through the water outlet 62 on the water box 6, at the moment, noise can be generated by the backflow of the bubbles, normal use experience of a user can be influenced, and the noise generated when the bubbles flow back can be heard by the user.

Compared with the prior art, the water box 6 is provided with the water outlet 62 and the air vent 61, the water outlet 62 is used for draining water, the air vent 61 is used for air bubble backflow, so that air bubbles enter the water box 6 through the air vent 61 instead of entering the water box 6 through the water outlet 62 when backflow of the air bubbles, backflow noise generated by the water outlet 62 together with condensed water when the air bubbles backflow is avoided, and compared with the prior art, the air bubble backflow noise reducing device has the effect of obviously reducing the air bubble backflow noise. Meanwhile, the utility model is also provided with the water box joint 8, the water box joint 8 is connected between the water box 6 and the water drain main pipe 7, the water box joint 8 is provided with the water drain connecting pipe 81 connected with the water outlet 62 and the ventilation pipe 82 connected with the ventilation port 61, the ventilation pipe 82 is arranged above the water drain connecting pipe 81, the ventilation pipe 82 is communicated with the upper side pipe wall of the water drain connecting pipe 81, air bubbles flowing from the water drain main pipe 7 to the upper side of the water drain main pipe 7 firstly pass through the water drain connecting pipe 81 and then enter the ventilation pipe 82 through the opening of the upper side pipe wall of the water drain connecting pipe 81, and the air bubbles enter the ventilation port 61 positioned in the water box 6 through the ventilation pipe 82 so as to separate the reflux direction of the air bubbles from the flow direction of the condensed water, the condition that the reflux noise of the air entering the water box 6 through the water outlet 62 is large when the air bubbles reflux is prevented, and the noise in the use process of the refrigerator 100 is reduced.

In some embodiments of the refrigerator 100 of the present utility model, the water box 6 has a sidewall extending in the height direction of the cabinet 1 between the top plate 12 and the base 13 and a bottom plate 63 coupled to the bottom of the sidewall, and a drain port 62 is formed obliquely downward at a corner of the bottom of the sidewall and the bottom plate 63.

Specifically, the bottom plate 63 of the water box 6 is funnel-shaped, and the water outlet 62 is at the lowest position of the bottom plate 63 of the water box 6, so that water on the bottom plate 63 of the water box 6 can gather toward the water outlet 62 by gravity and flow out through the water outlet 62.

The water box 6 further comprises a stopper 65 provided at the inlet end of the drain opening 62, the stopper 65 serving to stop ice cubes formed by condensed water in the water box 6.

It should be noted that, because the temperature of the surface of the evaporator 51 is low, when the air containing water vapor flows through the surface of the evaporator 51, icing occurs on the surface of the evaporator 51, frozen ice cubes flow into the water box 6 along with condensed water on the surface of the evaporator 51, because the bottom plate 63 of the water box 6 is funnel-shaped, the ice cubes slide to the water outlet 62, because the pipe diameter of the water outlet 62 is small, if the ice cubes enter the water outlet 62, the water outlet 62 may be blocked, or the ice cubes are blocked at the opening end of the water outlet 62, so that the condensed water cannot smoothly flow into the water outlet 62, water accumulation phenomenon may occur in the water box 6, when the water accumulation in the water box 6 is large, water accumulation sometimes overflows from the water box 6, or the water accumulation covers the air permeable opening 61, so that the bubbles reflow again to the condensed water in the water box 6, and reflux noise is generated.

In the prior art, the water outlet 62 is not provided with the stop post 65, so that ice cubes can directly enter the water outlet 62 or block the water outlet 62 at the inlet end, and accumulated water in the water box 6 cannot be smoothly discharged. Compared with the prior art, the water outlet 62 is provided with the stop post 65 at the inlet end, the stop post 65 can stop ice cubes on one side of the stop post 65 far away from the water outlet 62 so as to prevent the ice cubes from entering the water outlet 62, prevent the ice cubes from blocking the inlet end of the water outlet 62, facilitate smooth drainage of condensed water in the water box 6, reduce the overflow of the condensed water in the water box 6 caused by the blockage of the main drainage pipe 7, and reduce the backflow of bubbles into the condensed water in the water box 6 again caused by the excessive coverage of the ventilation opening 61 by the condensed water in the water box 6, thereby reducing the probability of noise generation caused by backflow.

In some embodiments of the present utility model, the diameter of the ventilation opening 61 is smaller than that of the water outlet 62, and the diameter of the ventilation opening 61 gradually decreases from the end connected with the water box 6 to the end far away from the water box 6, which is beneficial to installing the ventilation pipe 82 of the water box joint 8 at the ventilation opening 61, and is convenient for installation.
