Detailed Description

The utility model provides a cold-stored refrigeration device, this cold-stored refrigeration device can be for refrigerator, refrigerator-freezer or other storing devices that have cold-stored and/or freezing function. Fig. 1 is a schematic structural view of a refrigerating and freezing apparatus according to an embodiment of the present invention, and fig. 2 is a schematic sectional view of the refrigerating and freezing apparatus according to an embodiment of the present invention.

Referring to fig. 1 to 2, a refrigerating and freezing device 1 of the present invention includes a box 10, and at least one storage compartment 11 is defined in the box 10. Further, the refrigerating and freezing device 1 may further include a door for opening and/or closing the storage compartment 11. One of the storage compartments 11 defines a heating chamber for accommodating an object to be processed, which can be heated, thawed, etc. Specifically, the housing 10 may define a plurality of storage compartments 11, for example, a refrigerating compartment, a freezing compartment and a temperature-changing compartment, which are different from each other in temperature and thus have different functions. The heating chamber may be formed in any one of the refrigerating compartment, the freezing compartment and the temperature varying compartment.

Further, the refrigerating and freezing device 1 further comprises an electromagnetic heating device for providing electromagnetic waves into the heating chamber to heat the object to be processed in the heating chamber. The electromagnetic wave provided by the electromagnetic heating device can be radio frequency wave, microwave and other electromagnetic waves with proper wavelength. The mode of heating the object to be processed by using the electromagnetic wave has high heating efficiency, uniform heating and can ensure the food quality. The electromagnetic heating device typically has an electromagnetic generating module 21 for generating an electromagnetic wave signal.

Particularly, the back of the box 10 is opened with a containing groove 12 having a backward opening, the backward opening of the containing groove 12 is covered with a cover 13 to define a containing space 14 between the containing groove 12 and the cover 13, and the cover 13 is opened with a heat dissipating hole for communicating the containing space 14 with the external environment of the box 10. The electromagnetic generating module 21 is disposed in the accommodating space 14, and a heat dissipation fan 31 is further disposed in the accommodating space 14 for driving airflow to flow between the accommodating space 14 and the external environment of the case 10 through the heat dissipation holes, so as to dissipate heat of the electromagnetic generating module 21.

Because the electromagnetic generating module 21 of the electromagnetic heating device is arranged in the containing space 14 formed by the containing groove 12 at the back of the box body 10 and the cover body 13, namely the electromagnetic generating module 21 is positioned outside the rear side of the box body 10, the electromagnetic heating device cannot occupy the storage space in the box body 10 and the heating space in the heating chamber, the storage space and the heating space are both large, and the space utilization rate is high.

Meanwhile, since the electromagnetic generating module 21 with high power is located outside the rear side of the box 10, the heat generated by the electromagnetic generating module is not dissipated in the box 10 to affect the storage temperature in the storage compartment. More importantly, the cover 13 is provided with heat dissipation holes through which heat generated by the electromagnetic generation module 21 can be dissipated. Further, still be equipped with radiator fan 31 in the appearance dress space 14, accessible radiator fan 31 drive air current accelerates to flow, makes the heat that electromagnetism generation module 21 produced distribute to external environment space more fast to cooling down electromagnetism generation module 21 fast, effectively, improved heating efficiency and heating effect, extension its life. The electromagnetic generation module 21 is arranged outside the rear side of the box body 10 and can be prevented from being seen by a user, and the overall appearance and the use experience of the user are improved.

Further, the cover 13 may be maintained flush with the rearward outer surface 10a of the case 10. Not only can the overall appearance of the refrigerating and freezing device 1 be improved, but also the box body 10 does not occupy too much space due to the arrangement of the electromagnetic generating module 21.

Fig. 3 and 4 are schematic cross-sectional views of different orientations at the receiving groove and the cover according to an embodiment of the present invention, the cross-sectional lines along fig. 3 and 4 being perpendicular to each other, and the straight arrows in fig. 3 indicate the general flow direction of the air flow. Referring to fig. 1 to 4, the heat dissipation holes include an air inlet hole 131 formed at the bottom of the cover 13 and an air outlet hole 132 formed at the top of the cover 13, so as to allow the air flow driven by the heat dissipation fan 31 to enter the accommodating space 14 through the air inlet hole 131 and flow out through the air outlet hole 132, thereby performing forced convection heat dissipation on the electromagnetic generating module 21. That is to say, the air inlet 131 and the air outlet 132 can be disposed at two opposite sides of the cover 13, so that the air flow forms a convection effect, thereby increasing the flow velocity of the air flow and further improving the heat dissipation efficiency of the electromagnetic generating module 21. According to the principle that hot air flow rises, the air inlet hole 131 and the air outlet hole 132 are arranged up and down, so that the air flow can flow quickly. Moreover, the air outlet 132 is especially disposed at the top of the cover 13, and the air inlet 131 is especially disposed at the bottom of the cover 13, so that the air flow with heat sent out through the air outlet 132 can directly rise without passing through the air inlet 131, and the heat can be prevented from entering the accommodating space 14 again to affect the heat dissipation effect.

In some embodiments, the air inlet holes 131 and the air outlet holes 132 can be both strip-shaped holes extending along the transverse direction, which not only increases the area of the air inlet and outlet holes and improves the air flow velocity, but also enables the air flow to uniformly flow to the electromagnetic generation module 21 after entering the containing space 14 and uniformly flow out, thereby improving the heat dissipation balance of the electromagnetic generation module 21.

In other embodiments, the air inlet opening 131 and the air outlet opening 132 may extend in the transverse direction and are divided into a plurality of small air inlets and a plurality of small air outlets 1321 by a plurality of partition ribs arranged side by side in the transverse direction. The mode not only can play a role in uniformly supplying air and balancing heat dissipation, but also can avoid unnecessary potential safety hazards caused by overlarge air inlet holes 131 and air outlet holes 132 (for example, fingers can stretch into the air inlet holes).

In some embodiments, a plurality of heat sinks 32 are further disposed in the housing space 14 for assisting in dissipating heat from the electromagnetic generating module 21. The arrangement of the heat sink 32 can increase the heat dissipation area of the electromagnetic generation module 21, thereby further improving the heat dissipation efficiency and the heat dissipation effect of the electromagnetic generation module 21.

Further, the plurality of heat dissipation fins 32 are arranged on the surface of the electromagnetic generation module 21 side by side and at intervals, so that the electromagnetic generation module 21 is directly connected with heat, and the heat transfer efficiency from the electromagnetic generation module 21 to the heat dissipation fins 32 is improved. The plurality of fins 32 are arranged in a side-by-side direction such that the gap between two adjacent fins 32 is matched with the flow direction of the air flow in the accommodating space 14, so that the air flow flows out through the air outlet 132 after passing through the gap between every two adjacent fins 32. Therefore, on one hand, the resistance effect of the radiating fins 32 on airflow flowing can be reduced, the airflow speed is improved, on the other hand, the sufficient contact between the airflow and the radiating fins 32 can be ensured, and therefore more heat can be taken away by the airflow.

Specifically, the air flow in the accommodating space 14 flows from the air inlet holes 131 at the bottom to the air outlet holes 132 at the top, i.e. the air flow flows in the direction from bottom to top in the accommodating space 14. The plurality of radiating fins 32 are arranged side by side in the transverse direction at intervals, and each radiating fin 32 extends in the up-down direction, so that the gap between two adjacent radiating fins 32 is penetrated up and down and is matched with the airflow direction.

In some embodiments, the heat dissipation fan 31 and the plurality of heat dissipation fins 32 are disposed on the rear surface of the electromagnetic generation module 21, the plurality of heat dissipation fins 32 are spaced apart from the cover 13 to form a gap 16, the gap 16 is communicated with the air inlet hole 131, the air inlet of the heat dissipation fan 31 faces the gap 16 between the plurality of heat dissipation fins 32 and the cover 13, and the air outlet 311 of the heat dissipation fan 31 faces the air outlet hole 132. Therefore, the airflow entering from the air inlet hole 131 can flow to the gap 16, and then flow to the air outlet hole 132 through the plurality of heat dissipation fins 32 or flow to the air outlet hole 132 through the heat dissipation fan 31.

Further, the heat dissipation fan 31 may be disposed between the plurality of heat dissipation fins 32 to reduce the space occupied thereby. The air inlet of the heat dissipation fan 31 may be flush with the rear end of the heat dissipation fins 32, and the air outlet of the heat dissipation fan 31 may be flush with the upper ends of the heat dissipation fins 32.

In some embodiments, the top of the front side of the cover 13 is provided with a transverse wind deflector 133 extending forward in a protruding manner, and two transverse sides of the cover 13 are respectively provided with a vertical wind deflector 134 extending forward in a protruding manner. That is, both the lateral wind deflector 133 and the two vertical wind deflectors 134 are projected and extended by the forward surface of the cover 13 toward the front side where the receiving groove 12 is located. The transverse wind deflector 133 and the two vertical wind deflectors 134 isolate the gap 16 from the air outlet and the air outlet 132 of the heat dissipation fan 31, so that the airflow entering through the air inlet 131 flows to the air outlet 132 after passing through the heat dissipation fins 32 and/or the heat dissipation fan 31. The arrangement of the transverse wind deflector 133 and the two vertical wind deflectors 134 prevents the air flow from leaking to other positions, and improves the flow rate and the heat dissipation effect of the air flow.

In some embodiments, the air inlet holes 131 and the air outlet holes 132 are covered with water blocking ribs 135, and the bottom of the water blocking ribs 135 is spaced apart from the rear surface of the cover 13, so that a gap is formed between the bottom wall of the water blocking ribs 135 and the rear surface of the cover 13 to allow the air flow to pass through. The setting of lid 13 can avoid electromagnetism to take place module 21 to be drenched or glue ash etc. by water to a certain extent, and fresh air inlet 131 and exhaust vent 132 department of lid 13 still cover specially has water blocking muscle 135, and the setting of water blocking muscle 135 neither can influence the normal flow of heat dissipation air current, can avoid again that the water logging of box 10 rear side causes electromagnetism to take place module 21 and wets or falls the ash in holding dress space 14, causes unnecessary potential safety hazard even.

Further, the water blocking rib 135 may be an arc-shaped water blocking rib which is convexly curved rearward from the rear surface of the cover body 13 from top to bottom. The water retaining rib 135 with such a shape is not only beautiful in shape, but also can be used for retaining water thereon, so as to prevent water drops from accumulating on the water retaining rib 135.

In some embodiments, a storage device 40 having a cylinder 41 and a door 42 is disposed in one of the storage compartments 11, and a heating chamber is formed in the storage device 40. When the heating process is performed, the door 42 closes the cylinder 41, thereby forming a closed heating chamber to prevent electromagnetic leakage.

Further, the electromagnetic heating device further comprises a radiation antenna 22 and a signal processing and measuring and controlling circuit 23 which are arranged in the cylinder 41, the radiation antenna 22 is electrically connected with the signal processing and measuring and controlling circuit 23, and the electromagnetic generating module 21 is electrically connected with the signal processing and measuring and controlling circuit 23 through a lead 50 which is preset in a foaming layer of the box body 10, and further electrically connected with the radiation antenna 22.

Specifically, the signal processing and measurement and control circuit 23 has a first radio frequency port 231 and a first signal transmission interface 232 led out from the rear wall of the storage device 40, the electromagnetic generation module 21 has a second radio frequency port 211 and a second signal transmission interface 212, the first radio frequency port 231 and the second radio frequency port 211 are connected through a radio frequency cable preset in a foaming layer of the box body 10, and the first signal transmission interface 232 and the second signal transmission interface 212 are connected through a signal transmission cable preset in the foaming layer of the box body 10.
