Detailed Description
The present invention will be described in detail below with reference to embodiments shown in the drawings. The embodiment is not intended to limit the present invention, and structural, methodological, or functional modifications of the invention according to the embodiment are included in the scope of the invention.
Referring to fig. 1 to 13, an embodiment of a refrigeration apparatus according to the present invention is shown, where the refrigeration apparatus includes a first compartment 1, a second compartment 2, a refrigeration component (not shown) disposed in the first compartment 1, and an air duct component that cooperates with the refrigeration component to supply air and return air to the second compartment 2, where the air duct component includes an integrally disposed air supply structure and an air return structure, the air supply structure is disposed in a foaming cavity between the first compartment 1 and the second compartment 2, and the air supply structure is communicated with the first compartment 1 and the second compartment 2 along a height direction so as to supply cold energy from the first compartment 1 to the second compartment 2.
Specifically, as shown in fig. 1 and 2, a first embodiment of the refrigeration apparatus according to the present invention is a refrigerator, specifically, a three-door refrigerator disposed at intervals along a height direction, where the first compartment 1, the second compartment 2, and the third compartment 3 are a freezing compartment, a temperature changing compartment, and a refrigerating compartment (the drawing only shows a portion of each compartment). And the refrigerator comprises a refrigerating chamber, a temperature changing chamber and a freezing chamber from top to bottom in sequence along the height direction of the refrigerator, and the temperature changing chamber and the refrigerating chamber can be arranged above the freezing chamber at intervals along the transverse direction. In other embodiments, the refrigerator may be a double-door refrigerator, a side-by-side refrigerator, a french refrigerator, or other forms of refrigerators, and the refrigeration device may also be a refrigerator.
In this embodiment, the air return structure is an integral air return structure for returning air to the second compartment 2 and the third compartment 3, that is, an integral air return structure 4. The integral air return structural member 4 extends to one side of the second compartment 2 and the third compartment 3 along the height direction, and the integral air return structural member 4 is provided with a first air return inlet 41 and a second air return inlet 42 which are respectively communicated with the second compartment 2 and the third compartment 3 and an air return outlet 43 which is communicated with the first compartment 1. Therefore, the integral air return structural member 4 can return air to the second compartment 2 and also return air to the third compartment 3, so that the air return structural members are prevented from being respectively and independently arranged for the second compartment 2 and the third compartment 3, the cost is further saved, the occupied space of the air return structural member is reduced, and the volume ratio of the refrigerator is improved.
Meanwhile, in order to ensure the volume rate, the middle position of the liner is usually set in a backward concave manner for installing an air supply structure for refrigerating the compartment, and the integral air return structural member 4 is arranged on one side of the second compartment 2 and the third compartment 3 in an extending manner along the height direction, so that the integral air return structural member 4 is prevented from being arranged in the middle, and the front and rear directions of the refrigerator are too thick, and the miniaturization design of the refrigerator is facilitated under the condition of ensuring the volume rate of the refrigerator.
Furthermore, since the second compartment 2 is a temperature-changing chamber and is disposed below the third compartment 3, which is a refrigerating chamber, when the second compartment 2 is used for freezing, the internal temperature of the second compartment is lower than 0 degrees, and then the return air temperature of the second compartment 2 is also lower than 0 degrees, so that the first return air inlet 41 is closer to the return air outlet 43 in the height direction, that is, the distance between the first return air inlet 41 and the return air outlet 43 in the height direction is smaller than the distance between the second return air inlet 42 and the return air outlet 43 in the height direction, and further the return air of the second compartment 2 affects the return air of the third compartment 3 as less as possible, and the frost of the hot humid air returned by the third compartment 3 is reduced.
Of course, in other embodiments, if the second compartment 2 and the third compartment 3 are disposed above the first compartment 1 along the transverse direction, the integral return air structural member 4 may be applicable, and only the structure and the installation position need to be readjusted, for example: the integrated return air structural member 4 is of a T-shaped structure and is arranged at the rear sides of the second room 2 and the third room 3 and is positioned at the middle position, so that the distance between the first return air inlet 41 and the second return air inlet 42 is relatively short, and the integrated return air structural member 4 is beneficial to miniaturization. Or the integral air return structural member 4 is in an L-shaped structure, and a part extending along the transverse direction can be arranged in the foaming layer space between the second compartment 2, the third compartment 3 and the first compartment 1, and a part extending along the height direction can be arranged at one side of the transverse direction as in the embodiment.
As shown in fig. 6 to 9, in the present embodiment, the integral return air structural member 4 includes a foam seat 44 and a foam cover 45 mounted to be matched with each other in the front-rear direction, and a fixing structure for fixedly connecting the foam seat 44 and the foam cover 45, the fixing structure includes a positioning portion 461 protruding from one of the foam seat 44 and the foam cover 45, and a positioning groove 462 recessed from the other for being matched with the positioning portion 461. Therefore, through the structure, the integrated return air structural member 4 is simple in structure, low in cost and easy to install.
The integrated air return structural member 4 further comprises a sealing structure formed between the foam seat 44 and the foam cover 45, the sealing structure comprises a protruding portion 471 protruding from one of the foam seat 44 and the foam cover 45, a groove 472 concavely arranged from the other to be matched with the protruding portion 471, an air return passage for circulating air in the second compartment 2 and the third compartment 3 is formed between the foam seat 44 and the foam cover 45, and the protruding portion 471 is arranged beside the air return passage. By providing the protruding portion 471 and the groove 472, return air leakage from the gap between the foam seat 44 and the foam cover 45 can be effectively reduced, thereby ensuring normal circulation operation of the refrigeration system.
In this embodiment, the integral return air structure 4 further has a reinforcing portion 48 disposed within the return air duct, the reinforcing portion 48 protruding from the foam seat 44 and/or the foam cover 45 and disposed adjacent the second return air inlet 42. By providing the reinforcement 48, the risk of the foam material pressing against the foam seat 44 or the foam cover 45 being damaged during foaming is reduced.
Because the second compartment 2 is a temperature-changing chamber, when the second compartment 2 is used for the freezing chamber, the return air temperature of the second compartment 2 is low, so that the return air of the third compartment 3 is easy to influence, and the return air passage is frozen. Therefore, the integrated return air structural member 4 of the present invention further comprises a temperature control device disposed in the return air duct, wherein the temperature control device is used for preventing the return air temperature of the second compartment 2 and the return air temperature of the third compartment 3 from interfering with each other, thereby reducing the risk of freezing the return air duct.
Specifically, the return air duct includes a first return air duct 49 that is matched with the second compartment 2, and a second return air duct 410 that is matched with the third compartment 3, and the temperature control device is a partition 411 that protrudes from the foam seat 44 and/or the foam cover 45 to partition the first return air duct 49 and the second return air duct 410. In this embodiment, the partition 411 is formed by protruding from the foam seat 44 and the foam cover 45, and the partition 411 has a foam structure, so that the return air of the second compartment 2 and the return air of the third compartment 3 can be effectively prevented from directly contacting, and the risk of freezing the second return air duct 410 is reduced. The partition 411 may not only perform the above-mentioned functions, but also perform the function of reinforcing the structure, and the reinforcing portion 48 is disposed in the second return air duct 410 and close to the second return air inlet 42, so as to cooperate with the partition 411 in the height direction to provide the function of reinforcing the structure.
Further, in order to ensure that the partition 411 can effectively avoid the direct contact between the return air of the second compartment 2 and the return air of the third compartment 3, a protrusion 412 and a recess 413 are provided between the two partitions 411, so as to seal the end of the partition 411, thereby reducing the risk of direct contact between the return air of the second compartment 2 and the return air of the third compartment 3. Of course, in other embodiments, when the partition 411 protrudes from one of the foam seat 44 and the foam cover 45, the other may be concavely provided with a recess 412 that mates with the partition 411.
To further reduce the interference of the return air of the second compartment 2 with the return air of the third compartment 3, the risk of freezing the second return air duct 410 is caused. The refrigeration apparatus of the present invention further includes a heating element (not shown) disposed in the return air duct, and by means of the cooperation between the heating element and the partition 411, the risk of freezing the second return air duct 410 is reduced to the maximum, however, in other embodiments, only one heating element and only one partition 411 may be separately disposed, and the adjustment may be performed according to actual needs. When the heating element is provided separately, it may be provided on the inner wall of the return air duct, or the integral return air structure 4 may include a mounting portion for mounting the heating element.
Specifically, the heating element is disposed on the surface or inside the partition 411, and in this embodiment, the heating element is disposed inside the partition 411, that is, the installation portion, that is, the partition 411, so that the integrity of the integrated return air structural member 4 is improved. Because the heating element is generally of a metal structure, the risk of direct contact of the heating element with the return air humid air can also be reduced, thereby reducing the risk of oxidation of the heating element and improving the working life of the heating element.
In this embodiment, the refrigeration assembly includes a compressor, a condenser, a dewing pipe, a capillary tube, and an evaporator connected to each other, and the heating element is connected between the condenser and the dewing pipe or between the dewing pipe and the capillary tube. Thereby heating the return air of the second and third compartments 2 and 3 by using the temperature of the high temperature gas, thereby reducing the risk of freezing the second return air duct 410. Of course in other embodiments, the heating element may be connected to a condenser or dew point removing tube by a heat transfer element, for example: is connected through a heat pipe. Or the heating element is heated by power supply control.
As shown in fig. 11 to 13, in order to further improve the efficiency of installation of the air duct assembly and the capacity rate of the refrigerator, the refrigerating apparatus of the present invention further provides a second embodiment, which is different from the first embodiment in that: the air supply structural member and the integrated return air structural member 4 are integrally arranged, so that the air duct assembly is assembled only by one-time installation, and the air duct assembly is quite efficient. Therefore, the air supply structural member and the integrated air return structural member 4 can be formed by only slightly adjusting the foam seat 44 and the foam cover 45 to match each other.
Specifically, the air supply structural member comprises a first air supply structural member 5 and a second air supply structural member 6 which are connected with the integral air return structural member 4, the first air supply structural member 5 is arranged in the foaming cavity between the first room 1 and the second room 2 so as to supply air to the second room 2, and the second air supply structural member 6 is arranged in the foaming cavity between the second room 2 and the third room 3 so as to supply air to the third room 3. I.e. the first air supply structural member 5 and the second air supply structural member 6 are respectively connected with the integral return air structural member 4 along the transverse direction. And the sealing structure is also suitable for an air supply structural member, so that the risk of air supply leakage is reduced, and the stability and reliability of refrigeration are ensured.
Through the arrangement, the foaming layer space between the first room 1 and the second room 2, the second room 2 and the third room 3 can be fully utilized to install the first air supply structural member 5 and the second air supply structural member 6, the thickness of the first air supply structural member 5 and the second air supply structural member 6 protruding out of the rear side of the liner is greatly reduced, the miniaturization design of the refrigerator is facilitated, meanwhile, the liner is not required to carry out excessive abdication on the first air supply structural member 5 and the second air supply structural member 6, so that the volume rate of the refrigerator can be ensured, and the first air supply structural member 5 and the second air supply structural member 6 occupy the foaming layer space and can serve as a foaming layer, so that the use of foaming materials in the foaming process of the refrigerator can be reduced to a certain extent.
Of course, in other embodiments, the first air supply structural member 5 and the second air supply structural member 6 may be separately installed, and need not be integrally provided with the integral air return structural member 4. When the second chamber 2 and the third chamber 3 are disposed above the first chamber 1 along the transverse direction, the two air supply structural members are not required to be disposed, and the air supply structural members can be directly disposed in the foam layer space between the second chamber 2 and the third chamber 3, wherein the foam layer space is a space extending along the height direction, and then only air supply openings corresponding to the second chamber 2 and the third chamber 3 are required to be respectively disposed on the left and right sides of the air supply structural members.
In the present embodiment, the first air-blowing structural member 5 and the second air-blowing structural member 6 are disposed in the foam layer space between the first compartment 1 and the second compartment 2 and between the second compartment 2 and the third compartment 3, so that the air-blowing of the second compartment 2 is directly performed through the first compartment 1, but the air-blowing of the third compartment 3 is performed not directly through the first compartment 1 but through the first compartment 1 to the second compartment 2, and then through the second air-blowing structural member 6 to the third compartment 3 from the second compartment 2. And the traditional multi-compartment refrigerator is provided with the air supply structural members connected with the freezing chamber, and the number of the air supply structural members is large, the structure is large, and the arrangement is complex.
In this embodiment, since the second compartment 2 is a temperature changing compartment and the third compartment 3 is a refrigerating compartment, the temperature in the second compartment 2 can meet the requirement of the third compartment 3, and thus the cooling capacity in the second compartment 2 is sent to the third compartment 3 without affecting the storage of the articles in the third compartment 3.
Wherein the first air supply structural member 5 is provided with a first air supply port 51 communicated with the first compartment 1 and the second compartment 2, and the second air supply structural member 6 is provided with a second air supply port 61 communicated with the second compartment 2 and the third compartment 3. In the present embodiment, the number of the first air outlets 51 is greater than the number of the second air outlets 61. Therefore, when the second chamber 2 needs to be frozen, the first air supply opening 51 helps to lower the temperature of the second chamber 2 more quickly, and the number of the second air supply openings 61 is relatively small, so that the food material of the third chamber 3 is not easily frozen even if the temperature in the second chamber 2 is low. Of course, the first air supply port 51 and the second air supply port 61 may be provided with damper structures to adjust the air supply, thereby further improving the temperature control accuracy. Of course, in other embodiments, the number of the first air outlets 51 and the number of the second air outlets 61 may be equal, and only the first air outlets 51 are larger than the second air outlets 61.

The refrigeration equipment is further characterized by comprising a shell 7 arranged on the outer side of the inner container, a backboard 8 matched with the inner container and the shell 7, when the refrigeration equipment is assembled, the inner container and the shell 7 are assembled with each other, then an air duct assembly is installed, the other side of the air duct assembly along the transverse direction is attached to the inner wall of the shell 7, and finally the backboard 8 is installed, the rear side of the air duct assembly is attached to the inner wall of the backboard 8, so that the air duct assembly is positioned by the shell 7, the backboard 8 and the abdicating part 11, and therefore, the air duct assembly is fixed without additional fixing pieces, and the installation efficiency is greatly improved. Meanwhile, when the refrigerator finishes foaming, the foaming material is solidified, so that the fixing of the air duct assembly can be further enhanced, and the stable reliability between the air duct assembly and each compartment is ensured.
As shown in fig. 10, to further improve the fixing effect, structural strength and heat insulation effect of the air duct assembly, one side of the air duct assembly, which is matched with the inner wall of the housing 7 and the inner wall of the back plate 8, is arranged in a non-planar manner. Specifically, the side and/or the back of wind channel subassembly are wavy setting, and is uneven promptly, therefore, at the foaming in-process, wind channel subassembly can have more contact surface and foaming material to contact to improve fixed effect, not only, owing to wave structure, can also carry out spacingly to the wind channel subassembly, prevent to remove. The foaming layer structure and the wave structure are in concave-convex fit arrangement when the foaming material is solidified, so that limit is carried out. In addition, the protruding structure increases the thickness to some extent to improve structural strength and insulation effect.
In this embodiment, the wave structures are disposed at intervals from top to bottom, however, in other embodiments, the wave structures may be disposed at intervals along the front-rear direction, or may be disposed in combination with each other in both directions.
In order to ensure that the installation position of the air duct component can be effectively fixed, the back plate 8 is prevented from being installed, the air duct structure is deviated, and finally the situation that the surface of the air duct component cannot be normally filled in the foaming process is caused. The length of the protruding part of the wave structure can be increased, so that when the air duct component is installed, the protruding part is abutted against the inner wall of the shell 7 and the inner wall of the back plate 8, and then the air duct component is directly fixed by the abdication part 11 and the inner wall of the shell 7, and even if the back plate 8 is installed, the air duct component cannot deviate. Of course the convex portions of the wave structure may be fully or partially enlarged.
In addition, the invention provides another mode, namely, a plurality of fixing parts 9 can be respectively arranged on the side wall and the back surface of the air duct assembly in a protruding mode so as to be respectively abutted against the inner wall of the shell 7 and the inner wall of the back plate 8, and wiring grooves 91 are further concavely arranged on the fixing parts 9, so that wiring of the wire harness is facilitated.
In summary, the air duct assembly of the refrigeration equipment of the present invention is formed by integrally arranging the air supply structural member and the air return structural member, and the air supply structural member is arranged in the foaming cavity between the first compartment 1 and the second compartment 2. Therefore, not only the efficiency of the installation of the air duct assembly can be improved, but also the volume rate of the refrigerating equipment can be improved.
The above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention.
