Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Referring to fig. 1 and 2, fig. 1 is a sectional view of a refrigerator 1 according to a first embodiment of the present invention, and fig. 2 is a sectional view of the refrigerator 1 according to a second embodiment of the present invention, wherein fig. 1 shows a case where a drying space 140 and a moisturizing space 150 are in the same storage compartment, and fig. 2 shows a case where the drying space 140 and the moisturizing space 150 are in different storage compartments.

The present invention provides a refrigerator 1, which may generally include a cabinet 10 and a door 12.

The cabinet 10 may include a housing 120 and a plurality of inner containers 110, the housing 120 being positioned at the outermost side of the overall refrigerator 1 to protect the overall refrigerator 1. The plurality of inner containers 110 are wrapped by the outer shell 120, and a foaming layer 130 can be filled between the plurality of inner containers 110 and between each inner container 110 and the outer shell 120 to reduce outward heat dissipation of the inner containers 110. Each liner 110 may define a forwardly open storage compartment, and the storage compartments may be configured as a refrigerator compartment, freezer compartment, temperature change compartment, etc., with the number and function of the particular storage compartments being configurable according to the needs in advance.

The door 12 is movably disposed in front of the liner 110 to open and close the storage compartment of the liner 110, for example, the door 12 may be hinged to one side of the front of the case 10 to open and close the storage compartment in a pivoting manner.

In some embodiments, the cabinet 10 of the refrigerator 1 may further have a drying space 140 and a moisturizing space 150, and the humidity of the drying space 140 may be set to be smaller than that of the moisturizing space 150 so that a user can store in zones according to the degree of "happiness" of food.

In some specific embodiments, the drying space 140 and the moisturizing space 150 may be disposed in the same liner 110 (shown in fig. 1), for example, the drying space 140 and the moisturizing space 150 are both disposed within the refrigerating chamber of the refrigerator 1.

In other specific embodiments, the drying space 140 and the moisturizing space 150 may also be disposed in different liners 110 (shown in fig. 2), for example, the drying space 140 may be disposed within a refrigeration compartment and the moisturizing space 150 may be disposed within a temperature change compartment of the refrigerator 1.

The drying space 140 further has a water collecting tank 142 for collecting water, and in particular, a bottom wall of the inner container 110 provided with the drying space 140 may be recessed downward to form the water collecting tank 142. Since food or cold air streams often have some moisture in the store, the water may be vaporized by transpiration, respiration, etc. into the storage compartment, and the vapor may condense into liquid water, which may be collected by the sump 142.

Referring to fig. 3, fig. 3 is a schematic view of an atomizer 20 in a refrigerator 1 according to one embodiment of the present invention. The refrigerator 1 may further include an atomizer 20, the atomizer 20 being disposed within the moisturizing space 150, an inlet 212 of the atomizer 20 being in communication with the sump 142, an outlet 214 of the atomizer 20 being exposed to the moisturizing space 150 to controllably release an atomized mist into the moisturizing space 150.

That is, the refrigerator 1 of the present embodiment can transfer the water collected in the drying space 140 into the moisturizing space 150, and periodically release the water mist by using the atomizing device 20 disposed in the moisturizing space 150, so that not only the moisturizing space 150 and the drying space 140 can be maintained in respective reasonable humidity ranges (i.e., the humidity of the drying space 140 is reduced, the humidity of the moisturizing space 150 is increased), but also the collected water can be recycled, no special water supply device is required to be disposed for the moisturizing space 150, the structure of the moisturizing space 150 is simplified, and the difficulty and cost of installation and maintenance of the refrigerator 1 are reduced.

As described in the background art section, the storage compartment with moisturizing effect in the prior art needs to be configured with an external water source, so that an additional burden is inevitably added to the refrigerator, and the structure is complex, which is not beneficial to installation and maintenance.

In order to overcome the above-mentioned drawbacks of the prior art, the refrigerator 1 of the present embodiment collects water in the drying space 140 and transfers the collected water into the atomizing device 20 disposed in the moisturizing space 150, so as to release atomized water mist into the moisturizing space 150, thereby improving the humidity of the moisturizing space 150, and therefore, no special water supply device is required for the moisturizing space 150, and the difficulty and cost of installation and maintenance of the refrigerator 1 are reduced.

Referring to fig. 3, in some embodiments, the atomizing device 20 may further include a housing 210 and an atomizer 220, the housing 210 being fixed to an inner wall of the moisturizing space 150, the housing 210 having a water storage chamber 216 and an atomizing chamber 218 therein, the inlet 212 of the atomizing device 20 being in communication with the water storage chamber 216, the outlet 214 of the atomizing device 20 being in communication with the atomizing chamber 218, the atomizer 220 being disposed in the atomizing chamber 218 to convert water from the water storage chamber 216 into atomized water mist.

Specifically, the sump 142 may be in communication with the water storage chamber 216 through the inlet 212 of the atomizer device 20 to pre-store some water. The water storage cavity 216 may also be connected to the atomizer 220 in the atomizing cavity 218 through an atomizing inlet pipe 240, and when the humidity of the humidity maintaining compartment needs to be increased, the atomizing inlet pipe 240 directly discharges water onto the atomizer 220, and the atomizer 220 (e.g., ultrasonic vibrator) may convert liquid water into water mist and finally discharge the water mist into the humidity maintaining space 150.

Referring to fig. 3, further, the housing 210 further has an air inlet 219 communicating the moisturizing space 150 with the atomizing cavity 218, the atomizing device 20 may further include an atomizing fan 230, the atomizing fan 230 is disposed in the atomizing cavity 218, the atomizing fan 230 may promote to form an atomized air flow entering from the air inlet 219 and being discharged from the outlet 214 of the atomizing device 20, and the atomized air flow may carry water mist to be discharged into the moisturizing space 150 together, so as to improve the working efficiency, effectively reduce the storage weight loss of the food material, and maintain the freshness of the food material.

The atomizing fan 230 may be a centrifugal fan, and the air inlet 219 is oriented perpendicular to the outlet 214 of the atomizing device 20, so that the positions of the air inlet 219 and the outlet 214 of the atomizing device 20 are conveniently designed, and the centrifugal fan also has the characteristics of high wind pressure, so as to quickly blow water mist into the moisturizing space 150.

In addition, the atomizing fan 230 can accelerate the airflow velocity in the moisture-preserving space 150, not only improve the uniformity of the temperature of the moisture-preserving space 150, but also can uniformly spread the water mist as much as possible, and avoid re-condensing into water drops after local supersaturation.

In addition, the outlet 214 of the atomizing device 20 may be provided with a grille (not shown), and the area of the grille may be as large as possible, thereby further improving the humidification uniformity of the humidification space 150.

Referring to fig. 1 and 2, further, the refrigerator 1 may further include an embedded pipe 30, a booster pump 40 and a control valve (not shown in the drawings), wherein two ends of the embedded pipe 30 are respectively connected with the water collecting tank 142 and the water storage cavity 216, the booster pump 40 is disposed on the embedded pipe 30 to boost the water pressure in the embedded pipe 30, and the control valve is disposed on the embedded pipe 30 to control the on-off of the embedded pipe 30.

As can be seen from the above, in the case 10 of the refrigerator 1, the foaming layer 130 can be filled between the outer shell 120 and the inner containers 110, and between two adjacent inner containers 110, and the embedded pipe 30 can be disposed in the foaming layer 130, so as to not occupy the storage space 620 in the inner container 110.

In assembly, the pre-buried pipe 30 may be previously disposed between the outer case 120 and the inner container 110, then both ends thereof are respectively connected with the water collecting tank 142 and the water storage chamber 216, and finally the foaming layer 130 is formed through a foaming process, and the pre-buried pipe 30 is fixed therein. In addition, because the foaming layer 130 has a heat preservation function, the embedded pipe 30 is arranged in the foaming layer 130, so that the embedded pipe 30 can be prevented from being frozen and blocked, and the reliability is improved.

A liquid level meter can be further arranged in the water storage cavity 216, when the liquid level meter detects that the water level reaches a low early warning value, the booster pump 40 and the control valve can be opened in a linkage mode, and water in the water collecting tank 142 is guided from the embedded pipe 30 to the water storage cavity 216 for storage. A humidity sensor can be further arranged in the moisturizing space 150, when the humidity sensor detects that the humidity is smaller than a low early warning value, the atomization water inlet pipe 240 can be conducted through the valve, the atomizer 220 and the atomization fan 230 are started, the atomizer 220 is used for spraying water into the tap water storage cavity 216, the atomization fan 230 forms atomization airflow, the water mist is blown into the moisturizing space 150, and moisturizing of the moisturizing space 150 is completed.

In addition, since the water storage cavity 216 stores water in advance, when the atomizer 220 works, the water storage cavity 216 is communicated with the atomizer 220, so that the water on the surface of the atomizer 220 can be prevented from being too much to cause vibration, and the opening and closing times of the control valve are reduced as much as possible.

In some embodiments, the housing 210 may also be secured to the top wall of the moisturizing space 150 with the water storage chamber 216 positioned above the aerosolization chamber 218 and the outlet 214 of the aerosolization device 20 positioned at the bottom wall of the housing 210.

For the refrigerator 1, the rear wall of the inner container 110 is closer to the cooling air duct 160, so that the temperature of the rear wall is relatively lower, and the housing 210 is arranged on the top wall of the moisture-keeping space 150, that is, the top wall of the inner container 110, so that the atomizing device 20 can be prevented from directly contacting the air duct of the refrigerator 1, the influence on the air outlet of the cooling air duct 160 is reduced, and the freezing probability of water in the water storage cavity 216 is reduced.

In addition, since the mist formed by the atomizing device 20 still belongs to the liquid water, gravity has a certain influence on the diffusion thereof, if the mist is disposed on the bottom wall or the side wall of the moisture-keeping space 150, the mist may not reach the higher position of the moisture-keeping space 150 under the influence of gravity, and therefore, the mist is disposed on the top wall of the moisture-keeping space 150, and the mist is blown out from top to bottom, which is more favorable for the diffusion of the mist.

In some embodiments, the case 10 has a cooling air duct 160, the refrigerator 1 may further include an evaporator 70 and a drain pipe 80, the evaporator 70 is disposed in the cooling air duct 160 to provide cooling power to the refrigerator 1, the drain pipe 80 is disposed at a bottom of the evaporator 70 to drain defrost water on the evaporator 70, and the water collection tank 142 is further in communication with the drain pipe 80 to drain water collected in the water collection tank 142 from the drain pipe 80.

That is, in the present embodiment, the water collection tank 142 may be connected not only to the water storage chamber 216 of the atomizing device 20 but also to the drain pipe 80, so that water in the water collection tank 142 may be drained out of the refrigerator 1 through the drain pipe 80, thereby avoiding overflow of water collected by the water collection tank 142.

In addition, as can be seen from the foregoing, the humidity maintaining compartment can be disposed in the temperature changing compartment of the refrigerator 1, and the temperature adjusting range of the temperature changing compartment is generally wide, and when the temperature changes below zero, water mist may be frozen when the humidity is replenished to the humidity maintaining compartment, so that the control valve of the water collecting tank 142 to the water storage cavity 216 should be normally closed, water in the water collecting tank 142 can be discharged from the water discharging pipe 80, and water overflow of the water collecting tank 142 is avoided.

In some embodiments, the refrigerator 1 may further include a condensing plate 50, the condensing plate 50 being disposed at the drying space 140 and above the water collecting tank 142 to cool water vapor in the drying space 140 into liquid water, and discharging the liquid water into the water collecting tank 142.

The condensing plate 50 may be made of a metallic material having a good cold conducting property (e.g., aluminum, etc.) and provided on a side wall or a rear wall of the drying space 140 so that it can be maintained in a vertical state, and when the gaseous water in the drying space 140 encounters the cold condensing plate 50, it is condensed into water droplets, flows downward by gravity, and finally is collected in the water collecting tank 142.

Referring to fig. 4, fig. 4 is a schematic view of a condensing plate 50 in the refrigerator 1 according to one embodiment of the present invention. Further, the condensing plate 50 may be configured as a hollow structure having a receiving chamber 52 therein, and the receiving chamber 52 may be filled with a coolant 54 to store cold to cool the condensing plate 50.

Since the refrigerating system of the refrigerator 1 is intermittently operated, the cold storage agent 54 disposed in the condensation plate 50 can store cold when the refrigerating system is operated, and release cold to the condensation plate 50 when the refrigerating system is stopped, so that the condensation plate 50 always maintains a low temperature, thereby improving the collection efficiency.

Referring to fig. 5 to 7, fig. 5 is a sectional view of a refrigerator 1 according to a third embodiment of the present invention, fig. 6 is a sectional view of a refrigerator 1 according to a fourth embodiment of the present invention, and fig. 7 is a partial structural schematic diagram in the refrigerator 1 according to the third or fourth embodiment of the present invention, wherein fig. 5 shows a case where a drying space 140 has a drawer assembly 60 and the drying space 140 is in the same storage compartment as a moisturizing space 150, and fig. 6 shows a case where the drying space 140 has the drawer assembly 60 and the drying space 140 is in a different storage compartment from the moisturizing space 150.

In some embodiments, the refrigerator 1 may further include a drawer assembly 60, the drawer assembly 60 being operatively drawn out of or retracted into the drying space 140, and the drawer assembly 60 including a drawer body 610 having a storage space 620 therein, and the condensing plate 50 being disposed at an inner wall of the storage space 620.

In particular, the condensing plate 50 may be provided on a rear wall or a side wall of the storage space 620 to maintain a vertical state to collect water within the storage space 620.

Referring to fig. 7, further, the drawer body 610 is provided with a through-hole 630 below the condensing plate 50, and when the drawer assembly 60 is retracted into the drying space 140, the through-hole 630 is opposite to the water collection tank 142 so that water collected by the condensing plate 50 flows into the water collection tank 142 through the through-hole 630.

Fig. 7 shows one arrangement of the condensation plate 50, and when the condensation plate 50 is disposed on the rear wall of the storage space 620, the bottom wall of the drawer body 610 is provided with a through hole 630 opposite to the lower side of the condensation plate 50, and then the water collection tank 142 should be located below the through hole 630. That is, when the drawer assembly 60 is retracted into the drying space 140, the condensing plate 50, the through-hole 630 and the water collecting groove 142 are opposite to each other, so as to collect water of the storage space 620.

In addition, according to the above design concept, when the condensation plate 50 is disposed on the side wall of the storage space 620, the positions of the through holes 630 and the water collecting tank 142 are also changed correspondingly, which is not described herein.
