Detailed Description

Fig. 1 is a schematic structural view of a refrigerator 10 according to an embodiment of the present invention. The refrigerator 10 may generally include a cabinet 200, a condensation dehumidifying apparatus 300, and a heating apparatus 400.

In which a storage space 222 is formed inside the case 200. The storage space 222 may refer to a space for cryogenically preserving food materials or other items, such as a refrigerating space, or may refer to a space for cooking a food material to be cooked (such as meat), such as a cooking space.

The cabinet 200 may have a plurality of storage compartments 210 formed therein, each storage compartment 210 forming a storage space 222, and the refrigerating space or the aging space may be defined in any one of the storage compartments 210, for example, the storage compartment 210 may be directly used as the refrigerating space or the aging space. In some alternative embodiments, a storage container may be disposed in the storage compartment 210, and the interior of the storage container may be used as a refrigerating space or a curing space.

Fig. 2 is a front view of the internal structure of the refrigerator 10 according to one embodiment of the present invention, showing the storage space 222 and its surrounding components, which is a perspective view for convenience of example.

The condensation and dehumidification device 300 has a condensation portion 320 disposed in the storage space 222, and the condensation and dehumidification device 300 is configured to be controlled to start so as to condense water vapor in air around the condensation portion 320 on a surface of the condensation portion 320, thereby reducing humidity of the storage space 222. For example, after the condensation and dehumidification device 300 is controlled to start, the temperature of the condensation portion 320 may be lower than the temperature in the storage space 222, so as to promote the water vapor in the ambient air to condense on the surface of the condensation portion 320.

The heating device 400 is disposed corresponding to the condensing portion 320 and configured to heat the air after flowing through the condensing portion 320 when the condensing and dehumidifying device 300 is activated. In this embodiment, the heating device 400 may be disposed inside or outside the storage space 222 as long as it is ensured that the air after passing through the condensation part 320 may pass through the heating device 400. For example, the arrangement of the heating device 400 corresponding to the condensing portion 320 may mean that the heating device 400 is arranged adjacent to the condensing portion 320, and the heating device 400 is arranged downstream of the condensing portion 320 with respect to the airflow path flowing through the condensing portion 320.

Because the condensing and dehumidifying device 300 is disposed in the box 200, the condensing and dehumidifying device 300 can be controlled to start under the condition that the storage space 222 needs to be dehumidified, so that the water vapor in the storage space 222 is condensed on the surface of the condensing portion 320, and therefore, the refrigerator 10 of the embodiment can rapidly reduce the humidity of the storage space 222, which is beneficial to improving the fresh-keeping effect of the storage space 222.

The inventor has recognized that, due to the low surface temperature of the condensation portion 320, when the air in the storage space 222 flows through the condensation portion 320, the temperature of the air is reduced along with the condensation of the water vapor, that is, the temperature of the storage space 222 is affected while the humidity inside the storage space 222 is reduced by the condensation dehumidification device 300.

By providing the heating device 400, when the condensation and dehumidification device 300 is started, the air after flowing through the condensation portion 320 is heated by the heating device 400, which can make the air cooled by flowing through the condensation portion 320 obtain heat and raise the temperature, so that the refrigerator 10 of the embodiment can reduce the humidity of the storage space 222 and simultaneously can avoid influencing the temperature of the storage space 222.

The solution of the embodiment is particularly suitable for the case where the storage space 222 is a mature space. Ripening of different food materials is often required to be performed at a specific airflow flow rate, and the air in the storage space 222 needs to form an internal circulation airflow with a certain airflow flow rate. Based on the scheme of this embodiment, the refrigerator 10 can provide a suitable cooking atmosphere for the cooking of the food material, which is beneficial to forming a dry and constant-temperature internal circulation airflow.

A humidity sensor 800 may be disposed in the storage space 222 for detecting the humidity of the storage space 222, and the refrigerator 10 may determine whether to activate the condensation dehumidifying apparatus 300 according to the detection value of the humidity sensor 800. For example, when the detection value of the humidity sensor 800 exceeds a preset humidity threshold, it may be determined that the condensation and dehumidification device 300 is activated to ensure that the humidity of the storage space 222 is below the humidity threshold.

The condensation dehumidification device 300 may be a thermoelectric device, such as a device using electric energy for heat regulation, and the condensation portion 320 releases heat under the action of electric current to form a low-temperature portion of the condensation dehumidification device 300. For example, the condensation dehumidification device 300 may be a thermoelectric refrigerator.

The heating device 400 may be an electric heating element, such as any electric heating element including a heating wire, a heating sheet, a heating ring, a heating rod, or a heating tube.

In some alternative embodiments, the surface of the condensation portion 320 forms an inclined condensation surface to facilitate the collection of the condensed water. After the water vapor is condensed on the surface of the condensing part 320, the water vapor can be rapidly collected to the lower part of the condensing surface, so that most of the surface of the condensing surface is exposed, the effective contact area of the condensing part 320 and air can be increased, and the condensing efficiency of the water vapor is improved. For example, the condensation portion 320 may have a plate shape, and a condensation surface thereof may be obliquely disposed in the storage space 222. The inclination angle and the inclination direction of the condensation surface may be set according to actual needs, and for example, may be 5 to 30 ° inclined from the front to the back, or may be 5 to 30 ° inclined from one side of the transverse line to the other side.

The position of the condensation portion 320 in the storage space 222 may be arbitrarily set according to the actual space layout requirement, and may be set at the top, the bottom, the middle or the side of the storage space 222, for example. The surface of the condensation portion 320 may refer to a side of the condensation portion 320 facing the storage space 222. When the condensation portion 320 is disposed at the bottom of the storage space 222, the surface of the condensation portion 320 is an upper surface thereof.

In some alternative embodiments, the inclination of the condensing surface may be varied. For example, the condensation surfaces may extend obliquely downward from both lateral ends to a middle portion of the condensation portion 320 such that the middle portion of the condensation portion 320 forms a collecting groove 340 for the condensed water to collect. That is, the condensing surfaces of the present embodiment are not inclined in the same direction, but inclined in two different opposite directions, thereby forming the merging groove 340 at the middle of the condensing portion 320. For example, the cross-section of the condensation surface is substantially V-shaped.

With the above-described structure, the condensing portion 320 condenses the water vapor while collecting the formed condensed water to the collecting groove 340, which facilitates concentrated discharge of the condensed water.

It is to be understood that the terms "front", "back", "upper", "lower", "lateral", and the like, which refer to directions or positional relationships, are based on the directions or positional relationships shown in the drawings, and are used for convenience of description only, and do not indicate or imply that the described devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and therefore, should not be construed as limiting the present invention.

In some optional embodiments, the refrigerator 10 further includes a diversion device 500, which is formed with a diversion channel 510 for communicating with the confluence groove 340 and extending out of the storage space 222, and is configured to guide the condensed water converged into the confluence groove 340 out of the storage space 222. For example, the diversion channel 510 may extend to a drip pan or a press compartment of the refrigerator 10 to direct the condensate into the drip pan or the press compartment, so that the condensate may be directed along with the accumulated water in the drip pan or may be directly evaporated in the press compartment. The flow guiding device 500 may be an infusion tube, one end of which is communicated with the converging groove 340, and the other end of which is communicated with the water pan or the press bin.

In some alternative embodiments, the deflector 500 is disposed at the rear side of the storage space 222. For example, a mounting cavity for mounting the evaporator 900 and the like may be formed in the cabinet 200 at a rear side of the storage space 222, and the deflector 500 may be disposed in the mounting cavity.

Fig. 3 is a side view of the internal structure of the refrigerator 10 shown in fig. 2, showing the storage space 222 and its surrounding components, for convenience of example, in a perspective view.

The collecting groove 340 is inclined downwards from front to back, a water outlet is formed in the back wall of the storage space 222 and communicates the collecting groove 340 with the flow guide channel 510, so that the condensed water collected by the collecting groove 340 flows out of the water outlet and flows into the flow guide channel 510.

With the above structure, the condensed water condensed and attached to the surface of the condensing part 320 can be automatically collected to the collecting groove 340 by its own gravity, the condensed water collected by the collecting groove 340 can automatically flow out of the drain port and into the flow guide channel 510, and the condensed water formed on the surface of the condensing part 320 can be quickly and instantly drained.

Because the surface of the condensation portion 320 forms an inclined condensation surface, the condensation surface extends from the two lateral ends of the condensation portion 320 to the middle portion in an inclined manner, so that the convergence slot 340 for converging the condensed water is formed in the middle portion of the condensation portion 320, and the diversion device 500 can lead the condensed water converged in the convergence slot 340 out of the storage space 222 in time, therefore, the refrigerator 10 of the embodiment is beneficial to reducing or avoiding the re-evaporation of the condensed water generated in the storage space 222 due to retention.

In some optional embodiments, the refrigerator 10 may further include an airflow actuating device 600 disposed in the storage space 222 and configured to promote the airflow passing through the condensing portion 320 and the heating device 400. The airflow actuating device 600 may be a fan, such as a centrifugal fan, respectively, and in some embodiments, may be an axial fan, but is not limited thereto.

The heating device 400 is disposed downstream of the condensing part 320. It should be noted that the terms "upstream" and "downstream" refer to relative directions with respect to the fluid flow in the fluid path. For example, "upstream" refers to the direction of origin of the fluid, and "downstream" refers to the direction of destination of the fluid. The heating device 400 is disposed downstream of the condensing portion 320, that is, under the action of the airflow actuating device 600, the airflow in the storage space 222 flows through the condensing portion 320 first, and then flows through the heating device 400, so that the airflow absorbs heat and is heated.

Since the humidity of the air flow after passing through the condensing part 320 is low, the heating device 400 is disposed downstream of the condensing part 320, and the heating device 400 heats the air after passing through the condensing part 320, so that the condensation phenomenon of the heating device 400 can be reduced or avoided.

The condensation dehumidifying apparatus 300 and the heating apparatus 400 are respectively activated after being electrified. That is, by adjusting the power-on states of the condensation dehumidification device 300 and the heating device 400, the start-up and shut-down of the two devices can be controlled.

In some alternative embodiments, a return air duct is formed in the box 200, and is communicated with the storage space 222 through the return air opening 242, and is configured to guide the flow of return air after passing through the condensation portion 320 to the storage space 222 again. The heating device 400 is disposed in the return air duct.

That is, the heating device 400 is not disposed in the storage space 222, which can reduce or avoid temperature fluctuation in the storage space 222 caused by the heating device 400 heating other air (air that does not flow through the condensation portion 320) in the storage space 222. The return air opening 242 is located on a side wall of the storage space 222, for example, may be disposed at a bottom section of the side wall of the storage space 222, and the return air duct may extend upward from the return air opening 242 to a top section of the storage space 222 and communicate with the top section of the storage space 222 so as to redirect the flow of return air to the storage space 222.

In some further embodiments, the heating device 400 is disposed to extend along the direction of the air flow through the return air duct, which allows the return air flow to contact the heat-emitting surface of the heating device 400 sufficiently, thereby increasing the heating efficiency of the heating device 400. For example, the heating device 400 may be a heater chip and the flow of return air in the return air channel may flow along the chip surface of the heating device 400.

In some alternative embodiments, the return air duct has a first longitudinal section 244, a second longitudinal section 246, and a transverse section 248.

Wherein the first longitudinal section 244 and the second longitudinal section 246 are located at both lateral sides of the storage space 222, and the lateral section 248 is connected between the first longitudinal section 244 and the second longitudinal section 246. For example, the return air duct may be generally inverted U-shaped. The first longitudinal section 244, the second longitudinal section 246, and the transverse section 248 may each be formed within the foam of the case 200.

The transverse section 248 communicates with the storage space 222. That is, the return air flow may enter the storage space 222 from the top of the storage space 222. For example, the transverse segment 248 and the storage space 222 may be connected by way of an aperture.

In some alternative embodiments, the condensation portion 320 is disposed at the bottom of the storage space 222, for example, a shelf may be disposed above the condensation portion 320 to prevent the articles in the storage space 222 from directly contacting the condensation portion 320.

The airflow actuator 600 is disposed at the top of the storage space 222, and the air outlet end of the airflow actuator is disposed downward to blow the airflow of the storage space 222 downward to the condensation portion 320. Because the airflow actuator 600 is also adjacent to the air outlet end of the return air duct, the airflow actuator 600 can operate to promote a smooth internal circulation airflow path in the storage space 222.

The air return opening 242 is located on the sidewall of the storage space 222 and is disposed adjacent to the condensation portion 320, which shortens the distance between the air return duct and the condensation portion 320, so that the air flow blown down to the surface of the condensation portion 320 can quickly enter the air return duct from the air return opening 242 and be heated by the heating device 400 in time.

In some embodiments, at least one air supply outlet 212 is disposed on a back wall of the storage space 222 and configured to supply a heat exchange air flow to the storage space 222, so as to adjust the temperature of the storage space 222. The refrigerator 10 may further include an evaporator 900 disposed in the installation cavity of the cabinet 200 to exchange heat with air flowing therethrough, thereby generating the above-described heat-exchanged air flow. For example, a temperature sensor 700 may be disposed in the storage space 222 to detect a temperature of the storage space 222. The refrigerator 10 may control the opening and closing of the blowing port 212 and the heat exchange of the evaporator 900 according to a difference between a detection result of the temperature sensor 700 and a set temperature of the storage space 222.

The refrigerator 10 of the above embodiment combines the condensation dehumidifying apparatus 300 and the heating apparatus 400, and the refrigerator 10 can rapidly reduce the humidity of the storage space 222, which is beneficial to improving the fresh-keeping effect of the storage space 222, and can avoid the influence on the temperature of the storage space 222 while reducing the humidity of the storage space 222. The above embodiment is particularly suitable for the case that the storage space 222 is a ripening space, and the refrigerator 10 can simultaneously adjust the temperature and humidity of the ripening space to enable the ripening space to form an isothermal internal circulation airflow, thereby providing a suitable ripening atmosphere for the ripening of the food materials.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
