In particular, the first evaporator and the second evaporator of the present embodiment are disposed in a mutually fitting manner in the intermediate layer, and they are closely adjacent to each other. Thus, the thickness of the interlayer can be further reduced in this embodiment. Therefore, the embodiment improves the capacity and the space utilization rate of the refrigeration equipment.

In addition, the technical solution provided by the above embodiment of the present invention may further have the following additional technical features:

Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

The technical solutions of some embodiments of the present invention are described below with reference to fig. 1 to 9.

Some refrigeration devices 100 are provided in embodiments of the present invention, and the refrigeration device 100 in embodiments of the present invention may be a household refrigeration device or a commercial refrigeration device, and may specifically be a refrigerator or an ice chest. It should be noted that the technical solution of the embodiment of the present invention is particularly suitable for a side-by-side refrigerator or a cross-door refrigerator. Embodiments of the present invention aim to improve the capacity and space utilization of the refrigeration apparatus 100.

Specifically, as shown in fig. 1, in the related art, an evaporator 102 'of a refrigeration apparatus 100', such as a side-by-side refrigerator, is provided in the vicinity of a refrigerating side of the refrigerator, and cools the refrigerating chamber by natural heat conduction and heat convection. As shown in fig. 2, the evaporator 102' provided in the vicinity of the refrigerating side of the refrigerator in the related art is a plate-tube fin evaporator. As shown in fig. 3, the logic control method for the refrigeration device 100' in the refrigerator in the related art is as follows: and judging whether the refrigerating chamber and the freezing chamber are simultaneously refrigerated or not. The refrigerating chamber and the freezing chamber are used for refrigerating simultaneously, the compressor works, the fan works and the evaporator works. Whether the temperature in the refrigerating chamber reaches a first preset temperature is detected. When the temperature in the refrigerating chamber reaches a first preset temperature, the compressor stops working, the fan works and the evaporator stops working. Detecting whether the temperature in the refrigerating chamber is higher than a second preset temperature. The temperature in the refrigerating chamber is higher than a second preset temperature, and the compressor, the fan and the evaporator work. Among them, the capacity of the refrigerator in the related art is low, the space utilization rate is not ideal enough, which causes the space waste and the refrigerator volume is large. In view of the above, the embodiment of the present invention improves the structure and the control method of the refrigeration apparatus 100, thereby achieving the purpose of improving the capacity and the space utilization rate.

Example 1

As shown in fig. 4, the present embodiment provides a refrigeration apparatus 100 including: a first compartment 102, a second compartment 104, an intermediate layer 106, a first evaporator 108 and a second evaporator 110. An interlayer 106 is disposed between the first compartment 102 and the second compartment 104. And a first evaporator 108 provided on the side of the intermediate layer 106 close to the first chamber 102. And a second evaporator 110 provided on a side of the interlayer 106 adjacent to the second chamber 104. Wherein at least a portion of the first evaporator 108 and at least a portion of the second evaporator 110 cooperate to bring the first evaporator 108 and the second evaporator 110 into close proximity with each other.

The first compartment 102 of the present embodiment is adapted to refrigerate the stored item, and the second compartment 104 is adapted to refrigerate the stored item, wherein the refrigerating temperature of the first compartment 102 is lower than the refrigerating temperature of the second compartment 104. An interlayer 106 is disposed between the first compartment 102 and the second compartment 104, and serves to, among other things, separate the first compartment 102 from the second compartment 104.

The first evaporator 108 of this embodiment primarily provides cooling to the first compartment 102, and the second evaporator 110 primarily provides cooling to the second compartment 104. The intermediate layer 106 is hollow and has a certain accommodation space. In the present embodiment, a first evaporator 108 and a second evaporator 110 are disposed on the interlayer 106, wherein the first evaporator 108 is adjacent to the first compartment 102, and the second evaporator 110 is adjacent to the second compartment 104. The first evaporator 108 and the second evaporator 110 of the present embodiment are fitted to each other. The mutual matching means that at least a part of the second evaporator 110 and the first evaporator 108 are fixed to each other, or at least a part of the second evaporator 110 is embedded in the first evaporator 108, or at least a part of the first evaporator 108 and the first evaporator 108 are closely attached to each other. The purpose of arranging the first evaporator 108 and the second evaporator 110 to cooperate with each other is to bring the first evaporator 108 and the second evaporator 110 as close to each other as possible, and thereby to improve the capacity and space utilization of the refrigeration apparatus 100.

The present embodiment relatively arranges the first evaporator 108 and the second evaporator 110 above the intermediate interlayer 106, and compared to the related art in which the evaporators are arranged outside the interlayer, the present embodiment saves the space occupied by the evaporators, thereby saving the internal space of the refrigeration apparatus 100. In particular, the first evaporator 108 and the second evaporator 110 of the present embodiment are disposed in a mutually fitting manner in the intermediate layer 106, and they are closely adjacent to each other. Thus, the thickness of the interlayer 106 can be further reduced in this embodiment.

It should be noted that the cooperation of the present embodiment may refer to direct cooperation of the first evaporator 108 and the second evaporator 110, for example, the first evaporator 108 and the second evaporator 110 are attached to each other and are connected to each other, or refer to indirect cooperation of the first evaporator 108 and the second evaporator 110, for example, the first evaporator 108 and the second evaporator 110 are respectively disposed on two sides of the middle interlayer 106, and the positions of the two correspond to each other.

In addition, because the first evaporator 108 and the second evaporator 110 are matched and close to each other and are commonly arranged between the first compartment 102 and the second compartment 104, and the thickness of the intermediate interlayer 106 is relatively thin, in this embodiment, on the basis that the first evaporator 108 supplies cold to the first compartment 102 and the second evaporator 110 supplies cold to the second compartment 104, cold energy of the second evaporator 110 can be used for supplying cold to the first compartment 102 and/or cold energy of the first evaporator 108 is used for supplying cold to the second compartment 104, and the intermediate interlayer 106 with the relatively thin thickness is more beneficial to cold energy exchange between the first compartment 102 and the second compartment 104. In summary, in the embodiment, on the basis of reasonably utilizing the internal space of the refrigeration apparatus 100, the energy consumption of the refrigeration apparatus 100 is further reduced, and the energy utilization efficiency of the refrigeration apparatus 100 is improved.

Finally, the intermediate layer 106 may avoid the problem of taint between the refrigerated and frozen stores between the first compartment 102 and the second compartment 104. Due to the cooperation and proximity of the second evaporator 110 with the first evaporator 108 proximate the first compartment 102, the second compartment 104 is free from side wall frost and condensation due to the evaporation of refrigerant in the second evaporator 110, and melted frost and dripping condensation is prevented from flowing into the second compartment 104 during a shutdown condition of the refrigeration unit 100.

Example 2

The present embodiment provides a refrigeration apparatus 100, and in addition to the technical features of embodiment 1 described above, the present embodiment further includes the following technical features.

An interlayer 106 separates first compartment 102 and second compartment 104 from each other to prevent gas flow between first compartment 102 and second compartment 104.

As shown in fig. 4, the upper end of the intermediate layer 106 and the upper wall 134 inside the refrigeration apparatus 100 abut against each other, and the lower end of the intermediate layer 106 and the lower wall 136 inside the refrigeration apparatus 100 abut against each other. Thus, the interlayer 106 separates the first compartment 102 and the second compartment 104 from each other, and the first compartment 102 and the second compartment 104 are independently provided, and there is no air flow exchange therebetween. Therefore, the present embodiment can avoid the smell of the first chamber 102 and the second chamber 104 from tainting each other, and improve the user experience.

Example 3

The present embodiment provides a refrigeration apparatus 100, and in addition to the technical features of any of the above embodiments, the present embodiment further includes the following technical features.

The refrigerant circulation line of the first evaporator 108 and the refrigerant circulation line of the second evaporator 110 are disposed in series with each other.

Specifically, the refrigeration apparatus 100 is provided with a compressor, a condenser, a first evaporator 108 and a second evaporator 110, the compressor, the condenser, the first evaporator 108 and the second evaporator 110 are communicated with each other through a refrigeration cycle pipeline, and a refrigerant is circularly evaporated and condensed in the refrigeration cycle pipeline to realize refrigeration of the refrigeration apparatus 100. In this embodiment, the first evaporator 108 and the second evaporator 110 are serially connected to each other in the refrigeration cycle pipeline, so as to achieve the purpose of sharing the cooling capacity between the two evaporators and further reduce the energy consumption of the refrigeration equipment 100.

Example 4

The first evaporator 108 is a fin evaporator. The second evaporator 110 is a plate-tube evaporator. The refrigerant can evaporate quickly and sufficiently in the fin evaporator to ensure that the first compartment 102 can achieve low temperature freezing. The thickness of the plate-tube evaporator is thinner, so that the space occupied by the evaporator can be reduced. In addition, the evaporator with the plate-tube structure is more convenient to be tightly fitted with the first evaporator 108, so as to further improve the capacity and the space utilization rate of the refrigeration equipment 100, and facilitate the cold exchange between the first evaporator 108 and the second evaporator 110, so as to further reduce the energy consumption of the refrigeration equipment.

Example 5

As shown in fig. 5 and 6, the present embodiment provides a refrigeration apparatus 100, and in addition to the technical features of any of the above embodiments, the present embodiment further includes the following technical features.

The second evaporator 110 includes: a tube end 130 and a plate end 132, the tube end 130 being provided with a refrigerant circulation line. The plate end 132 is provided with a plate-like structure. Wherein at least a portion of the plate end 132 cooperates with at least a portion of the first evaporator 108.

In other words, the second evaporator 110 of the present embodiment is a plate-and-tube evaporator. Wherein, because the plate end 132 of the plate-tube evaporator has a plate-like structure, it is more convenient to cooperate with the first evaporator 108, so as to achieve the purpose of making the first evaporator 108 and the second evaporator 110 closely approach.

Example 6

As shown in fig. 4, the present embodiment provides a refrigeration apparatus 100, and in addition to the technical features of any one of the above embodiments, the present embodiment further includes the following technical features.

The refrigeration apparatus 100 further comprises: a first air chute 112 and a second air chute 114. The first air duct 112 is disposed on the interlayer 106 and communicates with the first chamber 102. The second air duct 114 is disposed on the interlayer 106 and communicates with the second chamber 104. The first evaporator 108 is disposed in the first air duct 112, and the second evaporator 110 is disposed in the second air duct 114.

In other words, in the present embodiment, the first compartment 102 and the second compartment 104 are respectively provided with relatively independent air ducts. Compared with the related art in which the evaporator of the refrigerating compartment and the evaporator of the freezing compartment share at least one section of air duct, the present embodiment has the advantage that the evaporator and the air duct are respectively matched for the two compartments. The first air chute 112 and the second air chute 114 are completely independent of each other and are separated from each other by the intermediate layer 106. Therefore, compared with the related art of sharing part of the air duct, the present embodiment can further avoid the exchange of air flow between the two compartments, and prevent the stored objects from tainting odor. In addition, in the present embodiment, the first evaporator 108 and the second evaporator 110 are respectively disposed in the first air duct 112 and the second air duct 114, which is not only convenient for the two evaporators to directly and efficiently supply cold to the two compartments, but also saves the accommodating space required for installing the evaporators, thereby further achieving the purpose of increasing the capacity.

Example 7

The refrigeration apparatus 100 further comprises: a first fan 116 and a second fan 118. The first fan 116 is disposed in the first air duct 112. The second fan 118 is disposed in the second air duct 114. The first air duct 112 is provided with a first air supply outlet 120 and a first air return opening 124, the first fan 116 is disposed at the first air supply outlet 120, the second air duct 114 is provided with a second air supply outlet 122 and a second air return opening 126, and the second fan 118 is disposed at the second air supply outlet 122.

The function of the fan is to better drive the cold flow into the compartment. The fan is arranged at the air supply opening, so that the cold energy generated by the evaporator can be effectively driven to be sent out to the compartment. The cold air density is higher, so the embodiment can arrange the air supply opening above the chamber and arrange the air return opening below the chamber, so that the cold air is settled from top to bottom, the purpose of fully utilizing the cold quantity is achieved, and the temperature uniformity degree in the chamber is improved.

Example 8

The second evaporator 110 is disposed on a first side of the second air duct 114, and a gap X is disposed between the second evaporator 110 and a second side of the second air duct 114 opposite to the first side.

Because a gap X for air circulation is left between the second air duct 114 and the second evaporator 110, the present embodiment utilizes the characteristic of large air thermal resistance, so that the temperature of the refrigeration sidewall of the refrigeration equipment 100 can not be too low during refrigeration, thereby better solving the sidewall condensation problem.

Example 9

The refrigeration apparatus 100 further comprises: and a drain structure 128, the drain structure 128 being provided at a lower position of the first evaporator 108 and/or a lower position of the second evaporator 110.

The drainage structures 128 of this embodiment may be grooves that are recessed inwardly along the surface of the evaporator or outwardly convex ridges. The drain structure 128 functions to collect, direct and drain condensate that slides or drips down the evaporator.

Example 10

As shown in fig. 5 and 7, the present embodiment provides a refrigerating apparatus 100, and in addition to the technical features of embodiment 9 described above, the present embodiment further includes the following technical features.

The drainage structure 128 has a groove-like inclined structure inclined from either end to the other end with respect to either end, and the inclination angle of the drainage structure 128 is 7 ° to 30 °. The inclination angle of the drainage structure 128 is set to 7 ° to 30 °, so that the condensed water can be conveniently and smoothly drained, and the condensed water is prevented from being deposited or collected.

Example 11

The refrigeration apparatus 100 further comprises: a temperature sensor is provided in the first compartment 102 and/or in the second compartment 104.

The temperature sensor may collect the temperature in the first compartment 102 and/or the second compartment 104, so as to obtain the compartment temperature of the refrigeration apparatus 100 in time, thereby adjusting the refrigeration condition of the refrigeration apparatus 100 according to the refrigeration condition.

Example 12

As shown in fig. 8, the present embodiment provides a control method of a refrigeration apparatus, which is adapted to control the refrigeration apparatus 100 according to any embodiment of the present invention, the refrigeration apparatus 100 further includes a compressor, and the control method of the refrigeration apparatus includes at least one of the following steps:

and S102, responding to a defrosting instruction, and controlling the compressor, the first fan and the second fan to be closed.

And S104, responding to the refrigeration instructions of the first chamber and the second chamber, and controlling the compressor, the first fan and the second fan to be started.

And S106, responding to a first compartment refrigeration instruction, and controlling the compressor and the first fan to be started.

And S108, responding to a second compartment refrigeration instruction, and controlling the compressor and the second fan to be started.

In the present embodiment, when the refrigeration apparatus 100 performs the defrosting operation, the compressor and the fan of the refrigeration apparatus 100 are turned off, the refrigerant stops circulating, and the cooling energy does not flow and is not transmitted. When the refrigeration apparatus 100 performs the freezing and refrigerating functions simultaneously and the first compartment 102 and the second compartment 104 refrigerate simultaneously, the operation of the compressor is controlled and the two fans operate simultaneously to deliver refrigeration to the first compartment 102 and the second compartment 104, respectively. When the refrigeration apparatus 100 performs only the freezing function but not the refrigerating function, the present embodiment controls the operation of the compressor and controls only the first fan 116 to be turned on, and the second fan 118 to be in a stopped state. When the refrigeration apparatus 100 performs only the refrigerating function but not the freezing function, the present embodiment controls the operation of the compressor and controls only the second fan 118 to be turned on, and the first fan 116 is in a stopped state.

Because the refrigeration equipment 100 provided by the embodiment of the invention is provided with the two evaporators which are arranged in parallel and matched with each other, the two evaporators provided by the embodiment of the invention can share the cold energy, and the utilization rate of the cold energy is improved. Therefore, in the control method of the refrigeration equipment in the embodiment, when any one compartment has no refrigeration demand, only the fan corresponding to the other compartment can be started. In this case, since the thickness of the interlayer 106 between the two compartments is small and the two evaporators can share the cooling capacity, the compartment with the cooling demand and the corresponding evaporator can be used to supply cooling to the compartment without the cooling demand to maintain the temperature of the compartment without the cooling demand.

In summary, by using the control method of the refrigeration apparatus of the present embodiment to control the refrigeration apparatus 100 of any embodiment of the present invention, the energy consumption of the refrigeration apparatus 100 can be further reduced.
