Background

With the progress of refrigerator technology, the existing refrigerator is endowed with more and more storage functions, such as defrosting, freezing beer and the like, besides the traditional refrigeration and freezing functions.

Detailed Description

The embodiments of the present invention will be described in detail below with reference to specific examples shown in the drawings. These examples are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

The embodiment provides a refrigeration appliance, the refrigeration appliance is preferably set up to the refrigerator, and it includes heat preservation box and heat preservation door body, a plurality of compartments are enclosed to the box, every the compartment is provided with at least one the heat preservation door body, with through the heat preservation door body opens or closes the compartment. Therefore, when the heat preservation door body opens the compartment, a user can put or take food into or out of the compartment; when the heat preservation door body closes the chamber, the chamber can maintain a low-temperature environment according to the set temperature of the chamber, and then low-temperature storage of food inside is achieved.

Referring to fig. 1, the compartments include a compartment 100, and the compartment 100 may be specifically configured as a temperature-variable compartment capable of being adjusted as needed within a large selectable temperature range (e.g., -18 to 5 ℃), but of course, the compartments may further include a refrigerating compartment adapted to store fruits and vegetables in a refrigerating temperature band (e.g., -2 to 10 ℃), and a freezing compartment adapted to freeze meat in a freezing temperature band (e.g., -18 to-5 ℃), that is, the refrigerator body encloses the refrigerating compartment, the freezing compartment, and the temperature-variable compartment denoted as the compartment 100 in the figure.

Further, the box body comprises inner containers which respectively enclose all compartments, such as a freezing inner container which encloses a freezing chamber, a refrigerating inner container which encloses a refrigerating chamber and a variable temperature inner container 10 which encloses a variable temperature chamber, and the box body further comprises heat insulation materials which are filled among the inner containers to realize the relative heat insulation of all the compartments, so that each compartment can stably maintain the respective temperature.

The refrigeration appliance also comprises a refrigeration system for providing refrigeration capacity for the compartments, the refrigeration system substantially comprises a compressor, a condenser, a throttling element and an evaporator, the compressor, the condenser, the throttling element and the evaporator are sequentially connected in series and are closed to form a circulation loop, and a refrigerant can circularly flow in the circulation loop and exchange heat with the external environment so as to correspondingly change the air temperature of the external environment.

In particular, the refrigeration appliance further comprises a refrigeration chamber and an air duct system.

The refrigerating chamber is arranged in the box body, the evaporator is contained in the refrigerating chamber, and when the refrigerant flows through the evaporator, the refrigerant can exchange heat with air in the refrigerating chamber so as to enable the air in the refrigerating chamber to form low-temperature cold air. The air duct system is used for communicating the refrigerating chamber with the plurality of chambers so as to convey low-temperature cold air in the refrigerating chamber to the plurality of chambers, thereby reducing the temperature of the plurality of chambers; meanwhile, the air duct system conveys the relatively high-temperature air of the plurality of compartments to the refrigerating compartment so as to be further manufactured into low-temperature cold air by the evaporator.

For example, the compartment 100 is communicated with the refrigeration compartment through the air duct system, the low-temperature cold air in the refrigeration compartment is conveyed into the compartment 100 through the air duct system, and the air in the compartment 100 returns to the refrigeration compartment through the air duct system.

Referring to fig. 2 and 3, the air duct system includes a return air inlet 12, a first air supply outlet 41 and a second air supply outlet 42, which are disposed in the compartment 100, and more specifically, the return air inlet 12 is disposed on a rear wall surface of the inner container 10, and the first air supply outlet 41 and the second air supply outlet 42 are disposed on an air duct module 40 installed inside the inner container 10 (i.e., inside the compartment 100). Thus, the cold air in the refrigeration compartment at low temperature partially exits the duct system through the first supply air outlet 41 and enters the compartment 100, partially exits the duct system through the second supply air outlet 42 and enters the compartment 100, and the air in the compartment 100 enters the duct system through the return air inlet 12 and then returns to the refrigeration compartment.

The refrigeration appliance further comprises a drawer 20 and a functional compartment 30.

The drawer 20 is movably housed in the compartment 100, and is movable in a manner of being pushed and pulled forward and backward with respect to the inner container 10. When the drawer 20 is pushed backwards to the rear end of the movement stroke, as shown in fig. 1, the drawer 20 is completely accommodated in the compartment 100, and the heat preservation door corresponding to the compartment 100 can be closed; when the drawer 20 is pulled out forward, as shown in fig. 4, an upper drawer opening of the drawer 20 may be at least partially exposed outside the compartment 100, thereby facilitating food access to the interior 200 of the drawer 20 through the drawer opening.

Referring to fig. 3, the pair of second supply vents 42 is located at the drawer 20 so that the cold air of the cooling compartment having a low temperature is supplied to the inside 200 of the drawer 20 immediately after leaving the second supply vents 42, i.e., the second supply vents 42 correspond to the drawer 20, so that the cold air of the low temperature supplied from the second supply vents 42 to the compartment 100 is directly supplied to the inside 200 of the drawer 20, not to the outside of the drawer 20.

Meanwhile, the drawer 20 is further provided with an air outlet 203, the air outlet 203 communicates the inside 200 of the drawer 20 with the outside of the drawer 20, and air in the inside 200 of the drawer 20 can be exhausted to the outside of the drawer 20; and the return air opening 12 allows the air outside the drawer 20 to return to the refrigeration compartment. Specifically, the air in the air duct system enters the interior 200 of the drawer 20 from the second supply opening 42, and is exhausted to the outside of the drawer 20 through the exhaust opening 203 after circulating in the interior 200 of the drawer 20; then, as shown by the hollow arrows in fig. 5, the air discharged from the air outlet 203 to the outside of the drawer 20 flows between the drawer 20 and the inner container 10, further leaves the compartment 100 via the air return opening 12, enters the air duct system, and finally returns to the refrigerating chamber.

The function box 30 is movably disposed in the drawer 20, and can be horizontally moved relative to the drawer 20 along a first direction, which is a left-right direction perpendicular to a drawing direction (i.e., a front-back direction) of the drawer 20 in this embodiment. That is, the width of the functional cartridge 30 in the left-right direction is smaller than the width of the interior 200 of the drawer 20 in the left-right direction, and the functional cartridge 30 can be translated left and right within the drawer 20. Of course, in a modified embodiment, the first direction may also be a front-rear direction parallel to the drawing direction (i.e., front-rear direction) of the drawer 20, in which case the depth of the functional cartridge 30 in the front-rear direction is smaller than the depth of the interior 200 of the drawer 20 in the front-rear direction.

Referring to fig. 6 and 7, the function cassette 30 is provided with a docking port 34, and the function cassette 30 has a function position and a rest position according to a positional relationship between the docking port 34 and the first blowing port 41 in a stroke in which the function cassette 30 moves horizontally in the first direction.

When the functional box 30 is in the functional position, as shown in fig. 3, the docking port 34 and the first air supply port 41 are distributed in a contraposition, that is, the docking port 34 and the first air supply port 41 are corresponding in position so that they can be docked, and at this time, the first air supply port 41 supplies the cold air in the refrigeration chamber at a low temperature to the interior 300 of the functional box 30, so that when the cold air in the refrigeration chamber leaves the air duct system from the first air supply port 41 and enters the compartment 100, the cold air at a low temperature directly enters the interior 300 of the functional box 30 through the docking port 34 to cool the interior 300 of the functional box 30, but not enters the exterior of the functional box 30.

When the functional box 30 is in the idle position, as shown in fig. 8, the docking port 34 and the first air blowing port 41 are distributed in a staggered manner, that is, the docking port 34 and the first air blowing port 41 are staggered so that they cannot be docked with each other, and at this time, the first air blowing port 41 supplies the low-temperature cold air in the refrigeration chamber to the inside 200 of the drawer 20 and the outside of the functional box 30, but not to the inside 300 of the functional box 30.

Thus, in the present embodiment, by arranging the movable functional box 30 in the drawer 20 and combining the arrangement of the second air supply outlet 42 and the first air supply outlet 41, when the functional box 30 is located at the functional position, the first air supply outlet 41 can supply air to the functional box 30 alone, so that the temperature inside the functional box 30 is rapidly reduced, and the functional box 30 realizes a special storage function such as ice beer, so that the ice functional box is attached to the drawer 20, the problem of low space utilization caused by the independent arrangement of the existing ice chamber is solved, and the storage temperature of the drawer 20 outside the functional box 30 is maintained substantially constant and is not excessively influenced by the special temperature environment in the functional box 30; when the functional box 30 does not need to exert a special storage function, the functional box 30 can be moved to the idle position, and at the moment, the drawer 20 can store conventional food, so that the functional box 30 can also be used as a sub-area in the drawer 20 to assist the arrangement and the partition placement of the food in the drawer 20, and the storage function diversity of the compartment 100 is improved; the overall space utilization rate of the refrigeration appliance is improved, and the problems of complex box body structure and high manufacturing cost caused by independent functional compartments are solved.

Preferably, the function box 30 can be also taken out from the drawer opening upwards from the inner part 200 of the drawer 20, so that the user can selectively place the function box 30 or take off the function box 30 according to personal use requirements, for example, for a user who has no requirement of ice beer, the function box 30 for realizing the ice beer function can be completely taken out from the drawer 20, and the user selectivity is increased.

Further, the refrigeration appliance also comprises a controller and a ventilation regulating mechanism.

The ventilation adjusting mechanism is disposed in the air duct system and connected to the controller, and adjusts the amount of air supplied to either or both of the first air supply outlet 41 and the second air supply outlet 42 under the control of the controller. In this way, under the control of the controller, the ventilation condition of the first air supply outlet 41 and/or the second air supply outlet 42 is regulated and controlled by the ventilation regulating mechanism, so as to realize the demand regulation of the storage temperature.

As described above, the compartment 100 is preferably provided as a temperature-variable chamber in the present embodiment. In general, the temperature-changing chamber may be operated as desired in a refrigerating storage mode and a freezing storage mode, respectively, in which: when the temperature-changing chamber operates in a refrigeration storage mode, the set temperature of the temperature-changing chamber is a refrigeration temperature band (for example, 2-5 ℃) suitable for fruit and vegetable storage, namely, the interior 200 of the drawer 20 basically and controllably maintains the refrigeration temperature band (for example, 2-5 ℃) environment; and when the variable temperature chamber is operated in the freezing storage mode, the set temperature of the variable temperature chamber is a freezing temperature zone (e.g., -18 to-5 ℃) adapted to the freezing of the meat, that is, the inside 200 of the drawer 20 is controlled to substantially maintain the environment of the freezing temperature zone (e.g., -18 to-5 ℃).

Further, when the temperature-changing chamber is in the cold storage mode and the function box 30 is in the function position, the ventilation adjusting mechanism may open the first air blowing port 41 and close the second air blowing port 42 for ventilation under the control of the controller. In this way, the function box 30 is started in the cold storage mode of the temperature changing chamber, the first air supply outlet 41 is opened for ventilation so as to supply low-temperature cold air to the inside 300 of the function box 30, and the inside 300 of the function box 30 is cooled, so that the function box 30 can realize special storage functions such as chilled beer; at this time, the second air supply outlet 42 is closed for ventilation, so that the space of the drawer 20 outside the functional box 30 is prevented from being excessively cooled, and the fruits and vegetables originally stored in the drawer 20 are prevented from being frostbitten due to too low temperature.

When the temperature-changing chamber is in the freezing storage mode and the function box 30 is in the function position, the ventilation adjusting mechanism can open the first air supply outlet 41 and the second air supply outlet 42 to ventilate under the control of the controller, and simultaneously, the air supply amount of the first air supply outlet 41 is larger than that of the second air supply outlet 42. In this way, the temperature changing chamber starts the functional box 30 in the freezing storage mode, the first air supply outlet 41 supplies low-temperature cold air to the inside 300 of the functional box 30 with relatively large air volume, and the inside 300 of the functional box 30 is rapidly cooled, so that the functional box 30 realizes special storage functions such as ice beer and the like; at this time, the second air supply outlet 42 supplies air to the drawer 20 space outside the functional box 30 with relatively small air volume, so as to maintain the temperature outside the functional box 30 to be basically constant, thereby meeting the storage requirement of the frozen meat originally stored in the drawer 20.

Preferably, the opening area of the first air supply opening 41 is larger than that of the second air supply opening 42, the ventilation adjusting mechanism comprises a first electric damper arranged at the first air supply opening 41 and a second electric damper arranged at the second air supply opening 42, the first electric damper can enable the first air supply opening 41 to open and close ventilation, and the second electric damper can enable the second air supply opening 42 to open and close ventilation under the control of the controller. In this way, when the first air blowing port 41 and the second air blowing port 42 are opened to ventilate, the opening area of the first air blowing port 41 is larger than that of the second air blowing port 42, and more air flows through the first air blowing port 41 in the same time. Of course, in a modified embodiment, the opening areas of the first air blowing port 41 and the second air blowing port 42 may be set to be the same, and the ventilation adjusting mechanism includes two speed-adjustable fans respectively provided at the first air blowing port 41 and the second air blowing port 42, so that the relative sizes of the respective air blowing amounts of the first air blowing port 41 and the second air blowing port 42 can be adjusted by adjusting the rotation speeds of the fans.

Preferably, in the refrigeration appliance according to an embodiment, the controller is configured to: upon receiving an instruction to activate the function box 30, querying a current mode of the temperature change chamber; if the current mode of the temperature-changing chamber is a cold storage mode, controlling the ventilation adjusting mechanism to enable the first air supply outlet 41 to open ventilation and the second air supply outlet 42 to close ventilation, specifically, the first electric air door opens the first air supply outlet 41, and the second electric air opening closes the second air supply outlet 42; if the current mode of the temperature changing chamber is the freezing storage mode, the ventilation adjusting mechanism is controlled to open both the first air supply outlet 41 and the second air supply outlet 42 for ventilation, and the air supply amount of the first air supply outlet 41 is greater than the air supply amount of the second air supply outlet 42, specifically, the first electric air door may fully open the first air supply outlet 41, and the second electric air door may fully open the second air supply outlet 42. So, when starting function box 30 and carrying out special memory function, according to the current mode of temperature-changing room is different, control first supply-air outlet 41 and the on-off state of second supply-air outlet 42, can realize function box 30 on the one hand if special storage demands such as beer in the ice town, avoid again influencing the outside drawer 20 storage temperature of function box 30 to the air supply of function box 30, both satisfy the frozen storage demand of the meat of original storage in the drawer 20, avoid the fruit vegetables of original storage in the drawer 20 to be frostbitten again.

Further, the function box 30 includes a box body 31 and a box cover 32. Wherein, the top of the box 31 has an opening for the user to take and put the storage object into the functional box 30; the box cover 32 is movably disposed at the top of the box body 31 to open or close the opening. Thus, by arranging the box cover 32 on the box body 31, when the functional box 30 is stored at a low temperature (for example, iced beer), the inside 300 of the functional box 30 is relatively sealed, so that the low-temperature cold air in the inside 300 of the functional box 30 is further prevented from overflowing to the outside of the functional box 30, the space temperature of the drawer 20 outside the functional box 30 is reduced, and meanwhile, the sufficient circulation of the cold air in the inside 300 of the functional box 30 is facilitated.

Specifically, the box body 31 roughly has a bottom box wall which is vertically opposed to the opening, a pair of box side walls which are oppositely arranged in the first direction, and a pair of box walls which are oppositely arranged in a second direction perpendicular to the first direction; as described above, in the present embodiment, the first direction is the left-right direction, and the second direction is the front-back direction, so that a pair of the first box side walls, i.e., the left box wall and the right box wall of the box body 31, and a pair of the box walls, i.e., the rear box wall 311 and the front box wall 312 of the box body 31, are provided.

Further, the drawer 20 has a bottom wall opposed up and down to the drawer opening, a pair of drawer walls opposed in the first direction, and a pair of side walls opposed in a second direction perpendicular to the first direction; as previously mentioned, the first direction is a left-right direction, and the second direction is a front-back direction, such that a pair of the drawer walls are the left and right side walls of the drawer 20, and a pair of the side walls are the rear and front side walls 21, 22 of the drawer 20.

The pair of box walls is movably supported on the pair of side walls, specifically, the rear box wall 311 of the function box 30 is movably supported on the rear side wall 21 of the drawer 20, and the front box wall 312 of the function box 30 is movably supported on the front side wall 22 of the drawer 20.

In the present embodiment, the rear side wall 21 and the front side wall 22 of the drawer 20 each have a support rail 23, the support rail 23 extending in the first direction; the rear case wall 311 and the front case wall 312 of the function case 30 each include a roller 33, and the roller 33 is supported on the support rail 23 and can horizontally move in the first direction along the support rail 23. Thereby, a supporting effect of the drawer 20 on the functional cartridge 30 is achieved, and a relative movement of the functional cartridge 30 with respect to the drawer 20 is achieved. Of course, in an alternative embodiment, the roller 33 may be replaced by a protrusion, and the supporting function of the drawer 20 on the functional box 30 and the movement of the functional box 30 may be realized.

Further, at least one of the rear sidewall 21 and the front sidewall 22 of the drawer 20 has a convex-concave varied portion 24, and when the function cartridge 30 is horizontally moved in the first direction, at least one of the rear cartridge wall 311 and the front cartridge wall 312 of the function cartridge 30 may be fitted to the convex-concave varied portion 24 to stop the function cartridge 30 at the function position. Thus, the convex-concave varied portion 24 actually limits the functional box 30 to be stably kept at the functional position, so as to ensure that the docking port 34 of the functional box 30 can be stably aligned to the first air supply port 41 when the functional box 30 is activated, thereby avoiding the situation that the docking port 34 is misaligned with the first air supply port 41 due to shaking or misoperation of the drawer 20, and if the docking port 34 is misaligned with the first air supply port 41 when the functional box 30 is activated, not only the functional box 30 cannot complete its special storage function, but also a large amount of cold air in the first air supply port 41 is accidentally supplied to the outside of the functional box 30 to cause temperature abnormality.

In the present embodiment, the rear sidewall 21 and the front sidewall 22 of the drawer 20 each have two convexo-concave varying portions 24.

Preferably, in this embodiment, referring to fig. 9, the convex-concave varying portion 24 is a groove recessed downward in the support rail 23, and when the roller 33 (or the convex block in the modified embodiment) is recessed in the groove, the functional cartridge 30 is located at the functional position. Or in a variant embodiment, the relief 24 may also be provided as a projection projecting upwards from the support rail 23, the functional cartridge 30 being located exactly in the functional position when the roller 33 (or the projection in a variant embodiment) abuts against the projection.

Further, the inner side of the support rail 23, for example, the front side of the support rail 23 on the rear side wall 21 of the drawer 20, and the rear side of the support rail 23 on the front side wall 22 of the drawer 20, are provided with an inwardly extending ledge 232, so that when the roller 33 (or the bump in the variation) is supported on the support rail 23, the roller 33 (or the bump in the variation) can be prevented from falling off the support rail 23 inwardly.
