Description

Refrigerating appliance

Technical Field

The invention relates to a refrigeration appliance, and belongs to the technical field of household appliances.

Background

With the progress of refrigerator technology, the existing refrigerator is endowed with more and more storage functions, such as thawing, iced beer, etc., in addition to the conventional refrigerating and freezing functions. For the iced beer function, an independent iced chamber is generally formed in the refrigerator body, that is, the iced chamber is individually enclosed by an inner container, and is isolated from other compartments (such as a freezing chamber, a refrigerating chamber, a temperature changing chamber, etc.) of the refrigerator by an insulating layer.

However, the setting temperature of the independently arranged icebox is between the refrigerating temperature and the freezing temperature, so that when icebox beer is not needed, the icebox can not meet the low-temperature storage requirement of meat freezing, and the icebox can not meet the storage requirement of fruits and vegetables due to low temperature and frostbite of the fruits and vegetables, so that the icebox can only be idle, and the space utilization rate of the refrigerator is seriously reduced; furthermore, for users who do not have the need for iced beer at all, the separate iced compartment, which cannot be removed, becomes the "chicken rib" compartment on the refrigerator; meanwhile, the independent iced chamber needs to be mutually isolated from other compartments (such as a freezing chamber, a refrigerating chamber, a temperature changing chamber and the like) of the refrigerator through a heat preservation layer, the space utilization rate of the refrigerator can be reduced due to the arrangement of the heat preservation layer, and the structure of the refrigerator body is more complex, so that simplification and cost reduction of refrigerator manufacture are not facilitated.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to specific examples shown in the drawings. The examples are not intended to limit the invention and structural, methodological, or functional modifications of the invention based on these embodiments are within the scope of the invention.

The embodiment provides a refrigeration appliance, the refrigeration appliance is preferably provided as a refrigerator, and comprises a heat preservation box body and a heat preservation door body, wherein a plurality of compartments are enclosed by the box body, and each compartment is provided with at least one heat preservation door body so as to open or close the compartment through the heat preservation door body. Thus, when the heat-insulating door body opens the compartment, a user can put or take out food into or from the compartment; when the heat-insulating door body closes the compartment, the compartment can maintain a low-temperature environment according to the set temperature of the compartment, so that the low-temperature storage of internal foods is realized.

Referring to fig. 1, the compartments include compartments 100, and the compartments 100 may be specifically configured as temperature-changing compartments that can be adjusted as needed within a wide optional temperature range (e.g., -18 to 5 ℃), but of course, the compartments may also include refrigerating compartments adapted for storing fruits and vegetables in a refrigerating temperature band (e.g., -2 to 10 ℃), and freezing compartments adapted for freezing meat in a freezing temperature band (e.g., -18 to-5 ℃), that is, the boxes enclose the refrigerating compartments, the freezing compartments, and the temperature-changing compartments labeled as compartments 100 in the drawing.

Further, the case includes inner containers that enclose respective compartments, such as a freezing inner container that encloses a freezing chamber, a refrigerating inner container that encloses a refrigerating chamber, and a temperature changing inner container 10 that encloses a temperature changing chamber, respectively, and further includes a heat insulating material filled between the respective inner containers to achieve relative insulation of the respective compartments, so that each compartment can stably maintain its own temperature.

The refrigeration device also comprises a refrigeration system for providing cold energy for the compartments, and the refrigeration system mainly comprises a compressor, a condenser, a throttling element and an evaporator, wherein the compressor, the condenser, the throttling element and the evaporator are sequentially connected in series and are closed into a circulation loop, and the refrigerant can circulate in the circulation loop and exchange heat with the external environment, so that the air temperature of the external environment correspondingly changes.

Specifically, the refrigeration appliance further comprises a refrigeration chamber and a wind channel 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 the air in the refrigerating chamber, so that the air in the refrigerating chamber forms low-temperature cold air. The air duct system is used for communicating the refrigerating chamber with the compartments so as to convey low-temperature cold air of the refrigerating chamber to the compartments, thereby reducing the temperature of the compartments; at the same time, the air duct system delivers relatively high temperature air of the compartments to the refrigeration compartment for further manufacture by the evaporator as low temperature cold air.

For example, the compartment 100 communicates with the refrigerating compartment through the air duct system, and cold air of a low temperature of the refrigerating compartment is transferred into the compartment 100 through the air duct system, and air in the compartment 100 is returned to the refrigerating compartment through the air duct system.

Referring specifically to fig. 2 and 3, the air duct system includes an air return port 12 provided in the chamber 100, a first air supply port 41 and a second air supply port 42, more specifically, the air return port 12 is provided on a rear wall surface of the liner 10, and the first air supply port 41 and the second air supply port 42 are provided on an air duct module 40 installed inside the liner 10 (i.e., inside the chamber 100). Thus, the cold air at low temperature of the refrigerating chamber leaves the air duct system partly via the first air supply opening 41 and enters the compartment 100, leaves the air duct system partly via the second air supply opening 42 and enters the compartment 100, whereas the air in the compartment 100 enters the air duct system via the return opening 12 and then returns to the refrigerating chamber.

The refrigerator further comprises a drawer 20 and a functional box 30.

The drawer 20 is movably accommodated in the compartment 100 and is movable in a front-rear push-pull manner with respect to the liner 10. When the drawer 20 is pushed back to the rear end of the movement stroke, as shown in fig. 1, the drawer 20 is completely contained in the compartment 100, and the thermal insulation door corresponding to the compartment 100 can be closed; when the drawer 20 is pulled forward, as shown in fig. 4, the upper drawer opening of the drawer 20 may be at least partially exposed to the outside of the compartment 100, thereby facilitating food access to the interior 200 of the drawer 20 through the drawer opening by a user.

Referring to fig. 3, the second air supply port 42 is positioned at the drawer 20 so that the low temperature Leng Kongqi of the refrigerating chamber is immediately supplied into the interior 200 of the drawer 20 when leaving the second air supply port 42, i.e., the positions of the second air supply port 42 and the drawer 20 correspond, such that the low temperature cold air introduced into the compartment 100 from the second air supply port 42 directly enters the interior 200 of the drawer 20, not the exterior of the drawer 20.

Meanwhile, the drawer 20 is further provided with an air outlet 203, and the air outlet 203 communicates the interior 200 of the drawer 20 with the exterior of the drawer 20, and can allow air in the interior 200 of the drawer 20 to be discharged to the exterior of the drawer 20; and return air inlet 12 allows air from outside drawer 20 to return to the refrigerated compartment. Specifically, the air in the duct system enters the drawer 20 inside 200 from the second air supply port 42, and is discharged to the outside of the drawer 20 through the air outlet 203 after circulating in the drawer 20 inside 200; then, as shown by 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 liner 10, further exits the chamber 100 through the air return port 12, enters the air duct system, and finally returns to the cooling chamber.

The functional cartridge 30 is movably disposed in the drawer 20 and is horizontally movable with respect to the drawer 20 in a first direction, which is a right-left direction perpendicular to a drawing direction (i.e., a front-rear 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 inside 200 of the drawer 20 in the left-right direction, and the functional cartridge 30 can be translated left-right within the drawer 20. Of course, in a variant 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 drawer 20 inside 200 in the front-rear direction.

Referring to fig. 6 and 7, the functional cassette 30 is provided with the opposite port 34, and the functional cassette 30 has a functional position and an idle position according to the positional relationship between the opposite port 34 and the first air supply port 41 in the course of the horizontal movement of the functional cassette 30 in the first direction.

When the functional box 30 is in the functional position, as shown in fig. 3, the opposite ports 34 are aligned with the first air supply ports 41, that is, the opposite ports 34 and the first air supply ports 41 are aligned with each other so that they can be abutted, and at this time, the first air supply ports 41 supply the low-temperature cool air of the cooling chamber into the functional box 30, so that the low-temperature cool air of the cooling chamber leaves the air duct system from the first air supply ports 41 and enters the compartment 100, and the air directly enters the functional box 30 through the opposite ports 34 to cool the interior 300 of the functional box 30, instead of entering the exterior of the functional box 30.

When the functional box 30 is at the rest position, as shown in fig. 8, the docking port 34 and the first air supply port 41 are staggered, that is, the docking port 34 and the first air supply port 41 are staggered so that they cannot be docked, and at this time, the first air supply port 41 supplies the cold air of the cooling chamber to the drawer 20 and the outside of the functional box 30, but not to the inside 300 of the functional box 30.

In this way, in this embodiment, by arranging the movable functional box 30 in the drawer 20 inside 200, and simultaneously, combining the arrangement of the second air supply opening 42 and the first air supply opening 41, when the functional box 30 is located at the functional position, the first air supply opening 41 can supply air to the functional box 30 alone, so that the interior 300 of the functional box 30 is cooled down rapidly, and the functional box 30 realizes a special storage function such as iced beer, so that the iced functional box is loaded in the drawer 20, the problem of low space utilization rate caused by independent arrangement of the existing iced chamber is solved, and at this time, the storage temperature of the drawer 20 outside the functional box 30 is maintained to be substantially constant and not excessively influenced by the special temperature environment in the functional box 30; when the function box 30 is not needed to play a special storage function, the function box 30 can be moved to the idle position, and the drawer 20 can store the conventional food at the moment, so that the function box 30 can also serve as a sub-area in the drawer 20 to assist in sorting and partition placement of the food in the drawer 20, and the storage function diversity of the compartment 100 is improved; the whole space utilization rate of the refrigeration appliance is improved, and the problems of complex box structure and high manufacturing cost caused by independent functional compartments are solved.

Preferably, the functional cartridge 30 is also removable from the interior 200 of the drawer 20 from the opening of the drawer for a user to selectively place the functional cartridge 30 or remove the functional cartridge 30 according to individual use requirements, for example, for a user who does not have a need for iced beer at all, the functional cartridge 30 for implementing the iced beer function can be completely removed from the drawer 20, increasing user selectivity.

Further, the refrigeration appliance also includes a controller and a ventilation adjustment mechanism.

The ventilation adjusting mechanism is arranged in the air duct system and connected with the controller, and adjusts the air supply quantity of either or both of the first air supply port 41 and the second air supply port 42 under the control of the controller. Thus, under the control of the controller, the ventilation condition of the first air supply port 41 and/or the second air supply port 42 is regulated and controlled by the ventilation regulating mechanism, so as to realize the on-demand regulation of the storage temperature.

As described above, the chamber 100 is preferably provided as a variable temperature chamber in the present embodiment. In general, however, the variable temperature chambers may be operated on demand in a refrigerated storage mode and a chilled storage mode, respectively, wherein: when the temperature changing chamber is operated in the cold storage mode, the set temperature of the temperature changing chamber is a cold storage temperature zone (e.g. 2-5 ℃) suitable for fruit and vegetable storage, that is, the interior 200 of the drawer 20 is basically controlled to maintain the cold storage temperature zone (e.g. 2-5 ℃) environment; when the temperature changing chamber is operated in the freezing storage mode, the set temperature of the temperature changing chamber is a freezing temperature zone (for example, -18 to-5 ℃) suitable for freezing meat, that is, the interior 200 of the drawer 20 is basically controlled to maintain the freezing temperature zone (for example, -18 to-5 ℃) environment.

Preferably, in the refrigeration appliance according to an embodiment, the controller is configured to:

querying the current mode of the variable temperature chamber when receiving an instruction to activate the function box 30; wherein, the instruction input of the user can be collected through a control panel or a mechanical key arranged on the thermal insulation door body, and the instruction input is given to receive the instruction for starting the function box 30;

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 port 41 to be opened for ventilation and enable the second air supply port 42 to be closed for ventilation; it can be understood that, at this time, the functional box 30 is at the functional position, the first air supply opening 41 is opened to supply cold air at low temperature to the interior 300 of the functional box 30, so as to cool the interior 300 of the functional box 30, so that the functional box 30 can realize special storage functions such as iced beer; meanwhile, the second air supply opening 42 is closed for ventilation to avoid excessive cooling of the space of the drawer 20 outside the functional box 30, so as to avoid frostbite of originally stored fruits and vegetables in the drawer 20 due to too low temperature;

if the current mode of the temperature changing chamber is a freezing storage mode, controlling the ventilation adjusting mechanism to enable the first air supply opening 41 and the second air supply opening 42 to be opened for ventilation, and enabling the air supply amount of the first air supply opening 41 to be larger than the air supply amount of the second air supply opening 42; it can be understood that, at this time, the functional box 30 is at the functional position, the first air supply opening 41 supplies cold air with low temperature to the interior 300 of the functional box 30 with relatively large air volume, and the interior 300 of the functional box 30 is rapidly cooled, so that the functional box 30 can realize special storage functions such as iced beer; meanwhile, the second air supply opening 42 supplies air to the drawer 20 outside the functional box 30 with relatively small air quantity, and maintains the temperature outside the functional box 30 to be basically constant, so that the storage requirement of freezing meat originally stored in the drawer 20 is met.

Thus, when the functional box 30 is started to perform a special storage function, the opening and closing states of the first air supply opening 41 and the second air supply opening 42 are controlled according to the different current modes of the temperature changing chamber, so that on one hand, the special storage requirements of the functional box 30 such as iced beer can be realized, the air supply to the functional box 30 is prevented from influencing the storage temperature of the drawer 20 outside the functional box 30, the storage requirements of the meat which is originally stored in the drawer 20 for freezing are met, and the fruits and vegetables which are originally stored in the drawer 20 are prevented from being frosted.

Preferably, the opening area of the first air supply port 41 is larger than the opening area of the second air supply port 42, the ventilation adjusting mechanism comprises a first electric air door arranged at the first air supply port 41 and a second electric air door arranged at the second air supply port 42, under the control of the controller, the first electric air door can enable the first air supply port 41 to open and close for ventilation, and the second electric air door can enable the second air supply port 42 to open and close for ventilation. Thus, when both the first air supply port 41 and the second air supply port 42 are opened, the first air supply port 41 has a larger opening area than the second air supply port 42, and more air flows through the first air supply port 41 at the same time. Of course, in a variant embodiment, the opening areas of the first air supply port 41 and the second air supply port 42 may be set to be the same, and the ventilation adjusting mechanism includes two adjustable speed fans respectively provided at the first air supply port 41 and the second air supply port 42, so as to adjust the respective air supply amounts of the first air supply port 41 and the second air supply port 42 by adjusting the rotational speeds of the fans.

Further, the functional cartridge 30 includes a cartridge body 31 and a cartridge cover 32. Wherein, the top of the box 31 is provided with an opening for a user to take and place the stored objects into the interior 300 of the functional box 30; the cover 32 is movably disposed at the top of the case 31 for opening or closing the opening. In this way, by providing the box cover 32 on the box body 31, the interior 300 of the functional box 30 is relatively sealed when the functional box 30 is stored at low temperature (such as iced beer), so that the low-temperature cold air in the interior 300 of the functional box 30 is further prevented from being scattered outside the functional box 30, the influence on the space temperature of the drawer 20 outside the functional box 30 is reduced, and meanwhile, the cold air is fully circulated in the interior 300 of the functional box 30.

In this way, by providing the air outlet 3120 at the front case wall 312 corresponding to the front side wall 22, the air of the inside 300 of the functional cassette 30 can be timely discharged from the nearby air outlet 203 to the outside of the drawer 20 when leaving the functional cassette 30 through the air outlet 3120, avoiding a large amount of cool air of the inside 300 of the functional cassette 30 from entering the inside 200 space of the drawer 20 outside the functional cassette 30 to cause a sudden change in the conventional storage temperature of the drawer 20.

In the embodiment of fig. 5, the front side wall 22 of the drawer 20 has an air guiding surface 221 located below the air outlet 203, and the air guiding surface 221 forms part of the inner surface of the drawer 20 and extends obliquely from bottom to top, as shown in the drawing, the extending direction X of the air guiding surface 221 from bottom to top forms an acute angle a with the vertical upward normal V. When the functional cartridge 30 is located at the functional position, the air outlet 3120 is lower than the air outlet 203 in the vertical direction, that is, relatively lower, and the air outlet 3120 is opposite to the air guiding surface 221 in the second direction, which is located right behind the air guiding surface 221. In this way, when the air in the interior 300 of the functional box 30 leaves the functional box 30 through the air outlet 3120, the air will flow forward and upward along the air guiding surface 221 under the guiding action of the air guiding surface 221, so as to be discharged from the nearby air outlet 203 to the outside of the drawer 20 in time, so as to avoid that a great amount of cold air in the interior 300 of the functional box 30 affects the temperature of the drawer 20 outside the functional box 30.

Of course, in a variant embodiment, by adjusting the position of the air outlet 203 or the air outlet 3120 in this embodiment, when the functional box 30 is located at the functional position, the air outlet 203 and the air outlet 3120 may be directly opposite to each other along the second direction, for example, the air outlet 203 is located directly in front of the air outlet 3120, or the air may be directly discharged to the outside of the drawer 20 through the air outlet 203 after leaving the functional box 30 through the air outlet 3120.

Further, in the present embodiment, the first air supply port 41 and the second air supply port 42 are disposed in order along the first direction, that is, in order along the left-right direction; when the functional cartridge 30 moves horizontally in the first direction in the drawer 20, the docking port 34 is aligned with or misaligned from the first air outlet 41 in a second direction perpendicular to the first direction, that is, the front-rear direction.
