The refrigerator and the drain valve thereof according to the present utility model will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, in some embodiments of the present utility model, a refrigerator includes a cabinet 10, an evaporator 20, a cooling fan 30, and a liner 40. Wherein the cabinet 10 defines a refrigerating compartment 11, and the evaporator 20 and the refrigerating fan 30 are disposed in the refrigerating compartment 11. The inner container 40 is installed in the case 10 and communicates with the cooling compartment 11, so that cool air in the cooling compartment 11 is introduced into the inner container 40 by the cooling fan 30 to cool food materials in the inner container 40. Further, the air in the liner 40 flows back again into the refrigerating compartment 11, and is cooled again by the evaporator 20.

As shown in fig. 2 to 4, in some embodiments of the present utility model, the refrigerator further includes a drawer 50, a sleeve 60, and a duct cover 70 disposed in the liner 40. Wherein the sleeve 60 is disposed at the bottom of the liner 40, and the drawer 50 is drawably installed in the sleeve 60. An air duct 80 is formed between the air duct cover 70 and the rear sidewall of the liner 40 above the sleeve 60.

As shown in fig. 3 and 5, in some embodiments of the present utility model, a plurality of air outlets 71 are provided on the duct cover 70, so that cold air in the air duct 80 is blown out from the air outlets 71. The rear side wall of the inner container 40 is provided with return air inlets 41 at both sides of the air duct cover plate 70 so that air in the inner container 40 flows back to the refrigerating compartment 11 through the return air inlets 41. An air inlet 42 communicated with the air duct 80 is arranged at the top of the rear side wall of the inner container 40, so that cold air in the refrigeration compartment 11 enters the air duct 80 from the air inlet 42.

As shown in fig. 4 to 6, in some embodiments of the present utility model, the refrigerator further includes an air conditioner 90, and the air conditioner 90 is mounted on the sleeve 60 and located at the rear upper side of the sleeve 60. Further, an opening (not shown in the drawings) communicating with the air conditioner 90 is provided at the rear upper side of the sleeve 60. Still further, the air conditioner 90 is installed in the duct 80.

As can be seen from fig. 4 and 5, the top wall of the sleeve 60 abuts against the bottom end of the duct cover 70 to raise the volume fraction of the sleeve 60 in the front-rear direction of the refrigerator.

With continued reference to fig. 4-6, in some embodiments of the utility model, an air conditioning apparatus90 includes a cathode 91, an anode 92, and an electrolyte (not shown in the figure) filled between the cathode 91 and the anode 92. The air regulating device 90 absorbs oxygen in the sleeve 60 through the cathode 91, and the air regulating device 90 releases oxygen to the outside of the sleeve 60 (specifically, to the air duct 80) through the anode 92. Specifically, the oxygen undergoes a reduction reaction at the cathode 91, namely: o (O) ₂ +2H ₂ O+4e ^- →4OH ^- . While oxidation occurs at anode 92 and oxygen is generated, namely: 4OH ^- →O ₂ +2H ₂ O+4e ^- 。

It will be appreciated by those skilled in the art that although the air outlet holes of the air regulating device 90 are not explicitly shown, in some embodiments of the present utility model, the air regulating device 90 has air outlet holes in communication with the anode 92 such that oxygen at the anode 92 is exhausted into the air duct 80 through the air outlet holes.

As can be seen from fig. 4 to 6, the cathode 91 and the anode 92 are each in a plate-like or sheet-like structure as a whole, and the cathode 91 and the anode 92 are arranged substantially horizontally to ensure that the space between the cathode 91 and the anode 92 is filled with an electrolyte, preventing the occurrence of a gap between the cathode 91 and the anode 92.

With continued reference to fig. 4-6, in some embodiments of the utility model, the interior of the sleeve 60 defines a liquid guide cavity 61 below the air regulating device 90, with a drain hole 62 provided in a sidewall of the liquid guide cavity 61. The liquid guiding cavity 61 is used for containing electrolyte leaked from the air conditioner 90, and the liquid draining hole 62 is used for draining the electrolyte in the liquid guiding cavity 61.

As will be appreciated by those skilled in the art, when the electrolyte of the air conditioner 90 leaks, the electrolyte falls into the liquid guide cavity 61 under the action of its own gravity, and then the liquid guide cavity 61 is discharged from the liquid discharge hole 62, so as to prevent the electrolyte from polluting the food materials in the drawer 50.

The cathode 91 of the air-conditioning device 90 is usually in a membrane structure and is easily pierced by sharp food materials, so that the arrangement of the liquid guide cavity 61 can also effectively protect the cathode 91 of the air-conditioning device 90 and prevent the cathode 91 from being pierced.

With continued reference to fig. 4-6, in some embodiments of the utility model, a drain hole 62 is formed on the rear sidewall of the sleeve 60, and the drain hole 62 is located at the lowest position of the bottom surface of the liquid guide cavity 61.

Further, the bottom surface of the liquid guiding chamber 61 is provided as a V-shaped surface facing left and right, and the bottom surface of the liquid guiding chamber 61 is inclined downward from front to back so that the conductive liquid in the liquid guiding chamber 61 can flow to the drain hole 62 entirely.

In addition, the bottom surface of the liquid guiding chamber 61 may be provided in any other possible shape as required by those skilled in the art, for example, the height of the bottom surface of the liquid guiding chamber 61 is gradually lowered in the direction approaching the liquid discharging hole 62.

As shown in fig. 4 and 5, a vent (not shown) is provided on the front side wall of the liquid guiding chamber 61, so that oxygen in the sleeve 60 enters the liquid guiding chamber 61 through the vent and contacts with the cathode 91 of the air regulating device 90. The refrigerator further includes a blower 110 disposed at the air inlet 42, the blower 110 being configured to drive air within the sleeve 60 into the liquid guide cavity 61, thereby accelerating the absorption of oxygen within the sleeve 60 by the air regulating device 90. Further, the refrigerator further includes a waterproof and breathable film 120 for covering the air inlet 42, so as to prevent water vapor in the sleeve 60 from entering the liquid guide cavity 61 to contact with the cathode 91, thereby affecting the reduction reaction.

In addition, a person skilled in the art may also provide a vent on the left or right side wall of the liquid guiding chamber 61, as desired.

Further, one skilled in the art may omit at least one of the front side wall, the left side wall, and the right side wall of the liquid guiding chamber 61 as needed. Further alternatively, the blower 110 and waterproof and breathable membrane 120 may be omitted as desired by those skilled in the art, thereby allowing oxygen within the sleeve 60 to automatically diffuse to the cathode 91 of the air regulating device 90.

As shown in fig. 4 and 5, in some embodiments of the present utility model, the refrigerator further includes a drain pipe 130 and a drain valve 140, the drain pipe 130 being hermetically connected to the drain hole 62 through a top end thereof, and the drain pipe 130 being hermetically connected to the drain valve 140 through a bottom end thereof.

As can be seen from fig. 4 and 5, the drain valve 140 is provided at the rear lower side of the drain hole 62 so that the electrolyte flowing out of the drain hole 62 smoothly flows to the drain valve 140.

As shown in fig. 7, in some embodiments of the present utility model, the drain valve 140 includes a valve body 141 and a valve 142, the valve 142 being pivotally connected to the valve body 141 by its top end. Further, a magnet 143 is provided on the valve body 141 so that the valve 142 automatically closes the valve body 141 under the action of the magnet 143. That is, the opened valve 142 can be attracted to the position closing the valve body 141 by the magnet 143, preventing the outside air from entering the liquid guide chamber 61.

In addition, a person skilled in the art may also arrange the magnet 143 on the valve 142 as desired. Alternatively, the magnet 143 is provided on the valve body 141 and the valve 142, respectively, and the magnet 143 on the valve body 141 and the magnet 143 on the valve 142 are attracted to each other.

Further, in order to allow the valve 142 to be rapidly opened when the conductive liquid is present in the drain valve 140, a magnet 143 may be provided on the valve 142, and then an electromagnetic coil is provided on the valve body 141, which generates a repulsive force with the magnet 143 on the valve 142 when energized, thereby opening the valve 142. Still further, the drain valve 140 further includes a first terminal and a second terminal connected in series with the solenoid, the first terminal and the second terminal being disposed in the valve body 141 at a distance from each other, the first terminal and the second terminal being turned on when immersed in the electrolyte, and thus energizing the solenoid.

Further specifically, the first terminal is connected in series with a power source, the second terminal is connected in series with an electromagnetic coil, and the electromagnetic coil is also connected in series with the power source. That is, the first terminal, the power source, the electromagnetic coil, and the second terminal are sequentially connected in series. When the conductive liquid in the air conditioner 90 leaks and flows to the drain valve 140, the first terminal and the second terminal are soaked by the electrolyte and conducted, so that the electromagnetic coil is electrified. The energized electromagnetic coil acts on the magnet 143 on the valve 142 to generate a repulsive force, which ejects the valve 142, thereby allowing the conductive fluid in the drain valve 140 to flow out.

As can be seen in fig. 5, a gap (not labeled) is formed between the sleeve 60 and the rear sidewall of the liner 40.

As shown in fig. 5 and 7, in some embodiments of the present utility model, the bottom of the inner container 40 is further provided with a through hole 43, and the through hole 43 is positioned below the gap and aligned with the drain valve 140 such that the conductive liquid flows out of the through hole 43 to the outside of the inner container 40 after being discharged from the drain valve 140.

Referring back to fig. 4 and 5, in some embodiments of the present utility model, drawer 50 includes a body 51, a first door 52 fixedly coupled to or integrally formed with body 51, a cover 53 mounted to first door 52, and a second door 54 rotatably coupled to first door 52 and located on a side of first door 52 remote from body 51. After drawer 50 is inserted into sleeve 60, first door 52 abuts the front end of sleeve 60 through its inner surface. Preferably, the first door 52 and the front end of the sleeve 60 are sealingly abutted together. For example, the inner surface of the first door 52 is provided with a gasket or gasket such that the first door 52 sealingly abuts the sleeve 60 through the gasket or gasket.

As shown in fig. 8 and 9, the first door 52 is provided with a pressure equalizing hole 521, and the pressure equalizing hole 521 is used to communicate both the inside and outside of the drawer 50 to equalize the air pressure in the drawer 50. The cover 53 is provided at a side of the first door 52 remote from the second door 54, and the cover 53 is pivotally connected to the first door 52 through its top end so that the cover 53 swings to a position to shield the pressure equalizing hole 521 by its own weight.

Optionally, at least one of the cover 53 and the first door 52 is provided with a magnet 143 so that the cover 53 is held in a position to shield the pressure equalizing hole 521 by the magnet 143, preventing the cover 53 from being opened by negative pressure in the sleeve 60 when the gas in the sleeve 60 is reduced.

Alternatively, a torsion spring may be provided between the cover 53 and the first door 52 as necessary by those skilled in the art to maintain the cover 53 in a position to shield the pressure equalizing hole 521 by the torsion spring.

With continued reference to fig. 8 and 9, the second door 54 includes an operation portion 541 located above the rotation axis thereof and a driving portion 542 located below the rotation axis thereof, the operation portion 541 being configured to allow an operator to pull the drawer 50, and the driving portion 542 being capable of penetrating the pressure equalizing hole 521 and pushing up the cover 53. Further, the second door 54 further includes a supporting portion 543 below the rotation axis thereof, and the supporting portion 543 is configured to abut against the first door 52 (as shown in fig. 8), so that an operator pulls the drawer 50 through the operating portion 541.

With continued reference to fig. 8 and 9, in some embodiments of the utility model, drawer 50 further includes a spring 55 disposed between first door 52 and second door 54, spring 55 being configured to apply a force to second door 54 that moves drive portion 542 away from first door 52 to ensure that cover 53 shields equalization hole 521.

As can be seen from fig. 8 and 9, the spring 55 is a tension spring provided above the rotation shaft of the second door 54. Specifically, one end of the spring 55 is hooked with the first door 52, and the other end of the spring 55 is hooked with the second door 54.

In addition, the spring 55 may be provided as a compression spring under the rotation shaft of the second door 54 as necessary by those skilled in the art.

As shown in fig. 8, when the user pulls the drawer 50 outward, the user pulls the operation portion 541 of the second door 54 outward, thereby moving the driving portion 542 toward the cover 53. When the supporting portion 543 comes into contact with the first door 52, the driving portion 542 has passed through the pressure equalizing hole 521 and opens the cover 53, and the air pressures on both the inside and outside of the drawer 50 are equalized. As the user continues to pull second door 54, drawer 50 moves with second door 54 and is withdrawn from sleeve 60.

As shown in fig. 9, when the user releases the second door 54, the second door 54 moves to the position shown in fig. 9 by the spring 55. At this time, the driving portion 542 no longer abuts against the cover 53, and the cover 53 returns to the position where the pressure equalizing hole 521 is blocked.

Based on the foregoing description, it will be understood by those skilled in the art that the present utility model enables the electrolyte leaked from the air conditioner 90 to be contained in the liquid guide chamber 61 and discharged to the outside of the sleeve 60 through the liquid discharge hole 62 by defining the liquid guide chamber 61 below the air conditioner 90 inside the sleeve 60 and providing the liquid discharge hole 62 on the sidewall of the liquid guide chamber 61. Therefore, the refrigerator of the present utility model overcomes the problem of contaminating food materials when the air conditioner 90 leaks electrolyte.

Further, by pivotally connecting the valve 142 to the valve body 141 through the top end thereof and providing a magnet 143 on at least one of the valve body 141 and the valve 142, the valve 142 can automatically close the valve body 141 under the action of the magnet 143, so that when the electrolyte is discharged cleanly by the drain valve 140, the seal can be automatically moved to prevent external air from entering the sleeve 60.

Still further, the present utility model also provides the pressure equalizing hole 521 on the first door 52, the cover 53 shielding the pressure equalizing hole 521, and the second door 54 for driving the cover 53, so that the user can open the cover 53 through the second door 54 when pulling the drawer 50, and the air pressure in the sleeve 60 is equalized with the ambient air pressure. Avoiding that the air conditioning device 90 consumes oxygen inside the sleeve 60, resulting in a lower air pressure inside the sleeve 60, making it difficult for the user to open the drawer 50. Thus, the present utility model also facilitates the opening of drawer 50 by the user.

In addition, in other embodiments of the present utility model, those skilled in the art may also dispose sleeve 60, drawer 50, air-conditioning device 90, etc. outside liner 40 as desired.

Thus far, the technical solution of the present utility model has been described in connection with the foregoing embodiments, but it will be readily understood by those skilled in the art that the scope of the present utility model is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined by those skilled in the art without departing from the technical principles of the present utility model, and equivalent changes or substitutions can be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical principles and/or technical concepts of the present utility model will fall within the protection scope of the present utility model.
