A refrigerator

Technical Field

The utility model relates to the technical field of refrigeration, in particular to a refrigerator.

Background Art

Refrigerators are a common household appliance that can store food at low temperatures, thereby extending the shelf life of food. In order to further improve the preservation effect of refrigerators, a technical solution has emerged that uses magnetic fields to assist in low-temperature storage of food. One function of the magnetic field is to achieve sub-zero temperature refrigeration of food, that is, to prevent food from freezing even at sub-zero temperatures, thereby further extending the preservation time and improving the preservation effect.

However, the existing magnetic field compartment and the cold storage compartment or the freezer compartment share a refrigeration system, and an air-cooled refrigeration system must be used to blow cold air to two different compartments. Since there is a certain difference in storage temperature between the magnetic field compartment and the other compartments, and the temperature requirement of the magnetic field compartment is relatively strict, the refrigeration time of the cold storage compartment or the freezer compartment needs to accommodate the magnetic field compartment, which affects the storage effect of the cold storage compartment or the freezer compartment.

A three-way valve, wherein the outlet end of the condenser is connected to the inlet ends of the first evaporator and the second evaporator respectively via the three-way valve, so as to controllably realize the separate connection of the condenser and the first evaporator, or the separate connection of the condenser and the second evaporator, or the simultaneous connection of the condenser and the first evaporator and the second evaporator through the three-way valve.

Optionally, the refrigerator further comprises:

a first capillary tube, the first capillary tube being disposed between the first evaporator and the three-way valve so that the refrigerant flows through the first capillary tube before flowing into the first evaporator; and

The second capillary tube is arranged between the second evaporator and the three-way valve so that the refrigerant flows through the second capillary tube before flowing into the second evaporator.

Optionally, a flow rate of the second capillary tube is greater than a flow rate of the first capillary tube.

Optionally, the first evaporator is provided with two refrigerant channels, one refrigerant channel is used to connect with the three-way valve, and the other refrigerant channel is used to connect with the outlet end of the second evaporator, so that the refrigerant flowing out of the second evaporator can flow through the first evaporator.

Optionally, the refrigerator includes a turbulent fan, which is arranged in the second chamber and is used to make the air in the second chamber flow.

Optionally, the turbulent fan is arranged at the top of the second chamber, and the air outlet end of the turbulent fan faces the top wall of the second chamber.

The refrigerator of the utility model is provided with a first evaporator and a second evaporator in the refrigerator, so that the first evaporator refrigerates the first compartment and the second evaporator refrigerates the second compartment, and a magnetic field generating device is provided in the second compartment to generate a magnetic field in the second compartment, that is, the second compartment as the magnetic field compartment uses the second evaporator alone, and does not need to share the evaporator with the first compartment. Therefore, the operation of the first evaporator used for refrigerating the first compartment and the second evaporator used for refrigerating the second compartment do not affect each other, that is, the refrigeration work of the first compartment and the second compartment do not affect each other, so that the magnetic field compartment does not affect the refrigeration work of other compartments, and on the basis of ensuring the refrigeration effect of the magnetic field compartment, it does not affect the refrigeration effect of other compartments. Moreover, the second evaporator is arranged close to the compartment wall of the second compartment to directly conduct cold energy to the second compartment, and there is no need to use an external blowing method for refrigeration, so as to avoid the problem of too low surface temperature of food caused by cold air blowing directly on food, thereby avoiding affecting the magnetic field preservation effect of food. At the same time, being close to the compartment wall allows the cold energy to be better diffused in the effective space in the compartment.

Furthermore, the refrigerator of the utility model connects the condenser to the first evaporator and the second evaporator via a three-way valve, and by adjusting the three-way valve, the condenser can be connected to the first evaporator alone to refrigerate the first chamber alone, or connected to the second evaporator alone to refrigerate the second chamber alone, or connected to the first evaporator and the second evaporator at the same time to refrigerate the first chamber and the second chamber at the same time, so that the first evaporator and the second evaporator can be cooled separately even when they share a compressor and a condenser, thereby simplifying the structure of the refrigerator while ensuring the refrigeration flexibility of the first chamber and the second chamber.

Furthermore, the refrigerator of the utility model is provided with a spoiler fan in the second chamber, and the spoiler fan is provided at the top of the second chamber, and the air outlet of the spoiler fan is directed toward the top wall of the second chamber. After the spoiler fan is turned on, the spoiler fan can cause the air in the second chamber to flow from bottom to top, and the airflow will be blocked in the process of flowing upward, so that the airflow is diffused to the surroundings, and the cold is distributed more evenly in the second chamber. Moreover, because the cold tends to be deposited at the bottom of the second chamber, the spoiler fan causes the airflow to flow from bottom to top, which helps to diffuse the cold deposited at the bottom of the second chamber to the top of the second chamber, and better improves the temperature uniformity of the second chamber.

As shown in FIG. 1 and FIG. 2 , in one embodiment, the refrigerator includes a housing 1, a first evaporator 2, a refrigeration fan 3, a magnetic field generating device 4, and a second evaporator 5. The housing 1 is formed with a first compartment 101 and a second compartment 102. The first evaporator 2 is arranged outside the first compartment 101, and the refrigeration fan 3 is used to transfer the coldness of the first evaporator 2 to the first compartment 101 to refrigerate the first compartment 101. The magnetic field generating device 4 is used to generate a magnetic field in the second compartment 102. The second evaporator 5 is arranged close to the compartment wall of the second compartment 102, and the second evaporator 5 is used to directly conduct coldness to the second compartment 102.

1 and 2, specifically, the first compartment 101 is a freezing compartment, the second compartment 102 and the first compartment 101 are distributed along the longitudinal direction of the refrigerator, and the second compartment 102 is located above the first compartment 101. In addition to the first compartment 101 and the second compartment 102, the refrigerator is further provided with two other compartments, one compartment is located above the second compartment 102 and serves as a refrigerating compartment, and the other compartment is located below the first compartment 101 and also serves as a freezing compartment.

It should be noted that, in some other embodiments, the refrigerator may also be provided with only the first compartment and the second compartment. In addition, in some other embodiments, the first compartment may also be a refrigeration compartment.

In addition, it should be noted that those skilled in the art can configure the number, function and layout of the compartments other than the first compartment and the second compartment according to the requirements, and the number and layout of the compartments in this embodiment are only an example.

Continuing to refer to FIG. 1 and FIG. 2 , a refrigeration chamber 103 is provided at the rear side of the first chamber 101, and the first evaporator 2 is provided in the refrigeration chamber 103, so that the cold energy can be released in the refrigeration chamber 103. The refrigeration fan 3 is provided between the refrigeration chamber 103 and the first chamber 101, and is in communication with the refrigeration chamber 103 and the first chamber 101. Specifically, the refrigeration fan 3 is directly in communication with the refrigeration chamber 103, and a transition chamber (not marked in the figure) is further provided at the rear side of the first chamber 101, and the refrigeration fan 3 is in communication with the first chamber 101 through the transition chamber. After the refrigeration fan 3 is started, it can promote the flow of air, thereby generating cold air carrying the cold energy in the refrigeration chamber 103, and the cold air enters the first chamber 101 through the transition chamber, so as to cool the first chamber 101.

As shown in FIG. 1 and FIG. 2 , the magnetic field generating device 4 is in the shape of a plate, and the magnetic field generating device 4 is arranged in the second chamber 102. The magnetic field generating device 4 is arranged on the inner side of the bottom wall of the second chamber 102 and is arranged in contact with the bottom wall of the second chamber 102. The magnetic field generating device 4 generates a magnetic field in the second chamber 102, that is, the second chamber 102 is a magnetic field preservation chamber. The food in the second chamber 102 can be affected by the magnetic field during storage, thereby improving the storage effect. Specifically, the magnetic field acting on the food can make the food refrigerated at sub-zero temperatures, that is, the food does not freeze at sub-zero temperatures, thereby further extending the preservation time and improving the preservation effect. In addition, under the action of the magnetic field, if the meat ingredients are frozen, small ice crystals can also be generated in the ingredients, thereby preventing the ice crystals from piercing the cells and causing the loss of juice.

Furthermore, the second evaporator 5 is also disposed in the second chamber 102, and the second evaporator 5 is disposed at the top of the second chamber 102. Specifically, the second evaporator 5 is disposed on the inner side of the top wall of the second chamber 102 so as to be close to the top side chamber wall of the second chamber 102. During the operation of the second evaporator 5, the cold energy generated by the second evaporator 5 directly cools the second chamber 102, that is, the cold energy is directly transferred to the second chamber 102.

In the scheme of this embodiment, by arranging the first evaporator 2 and the second evaporator 5 in the refrigerator, the first evaporator 2 refrigerates the first chamber 101, and the second evaporator 5 refrigerates the second chamber 102. The magnetic field generating device 4 is arranged in the second chamber 102 to generate a magnetic field in the second chamber 102, that is, the second chamber 102 as the magnetic field chamber uses the second evaporator 5 alone, and does not need to share the evaporator with the first chamber 101. Therefore, the first evaporator 2 for refrigerating the first chamber 101 and the second evaporator 5 for refrigerating the second chamber 102 do not affect each other, that is, the refrigeration work of the first chamber 101 and the second chamber 102 do not affect each other, so that the magnetic field chamber will not affect the refrigeration work of other chambers, and on the basis of ensuring the refrigeration effect of the magnetic field chamber, it will not affect the refrigeration effect of other chambers. Moreover, the second evaporator 5 is arranged close to the wall of the second chamber 102 to directly conduct cold energy to the second chamber 102, without using external blowing for refrigeration, avoiding the problem of cold air blowing directly on the food causing the surface temperature of the food to be too low, thereby avoiding affecting the magnetic field preservation effect of the food. At the same time, being close to the wall of the chamber allows the cold energy to be better diffused in the effective space in the chamber.

In addition, by arranging the second evaporator 5 at the top of the second chamber 102 , since the cooling capacity has a downward trend, it helps to fully diffuse the cooling capacity generated by the second evaporator 5 from top to bottom in the second chamber 102 , thereby helping to improve the temperature uniformity in the second chamber 102 .

It should be noted that, in some other embodiments, the magnetic field generating device may also be disposed at other locations in the second chamber, such as being disposed close to the left wall or right wall of the second chamber. In addition, the magnetic field generating device may also be disposed outside the second chamber.

It should be noted that, in some other embodiments, the second evaporator may also be arranged at other positions in the second chamber, such as the left side or the right side. In addition, the second evaporator may also be arranged outside the second chamber.

As shown in FIG. 1 and FIG. 2 , further, a heat preservation layer 6 is provided around the second compartment 102, and the second evaporator 5 is arranged on the side of the heat preservation layer 6 facing the second compartment 102. Specifically, the heat preservation layer 6 constitutes the compartment wall of the second compartment 102, that is, the second evaporator 5 is arranged in the second compartment 102. Specifically, the heat preservation layer 6 can be a structure composed of a heat preservation foam layer or other heat insulation materials. The heat preservation layer 6 surrounds the second compartment 102. Generally speaking, the second compartment 102 is a cubic chamber, and the front side of the second compartment 102 is an opening for users to take and put food, so the second compartment 102 has a top side wall, a bottom side wall, a left side wall, a right side wall and a rear side wall, and the top side wall, the bottom side wall, the left side wall, the right side wall and the rear side wall of the second compartment 102 are all composed of the heat preservation layer 6, so that the heat preservation layer 6 is arranged around the second compartment 102. The side of the heat preservation layer 6 facing the second compartment 102 is the inner wall surface of the second compartment 102. The second evaporator 5 is arranged on the side of the insulation layer 6 facing the second chamber 102 and on the top of the second chamber 102 , that is, the second evaporator 5 is arranged on the side of the insulation layer 6 constituting the top side wall of the second chamber 102 facing the second chamber 102 .

By arranging the heat preservation layer 6 around the second chamber 102 and arranging the second evaporator 5 on the side of the heat preservation layer 6 facing the second chamber 102, the heat preservation layer 6 forms a barrier between the inner space of the second chamber 102 and the outside, and the cold energy generated by the second evaporator 5 is isolated in the second chamber 102, so that the cold energy in the second chamber 102 can be prevented from diffusing outward, thereby helping to ensure that the temperature in the second chamber 102 is maintained at the set temperature for a longer time, helping to fully utilize the cold energy and reduce energy waste.

It should be noted that, in some other embodiments, the chamber wall of the second chamber may not be composed of an insulation layer, but may be composed of a material with good thermal conductivity. The insulation layer is arranged on the outside of the chamber wall. For example, polyurethane is foamed outside the chamber wall to form an insulation layer, and the second evaporator is arranged between the insulation layer and the chamber wall.

As shown in FIG3 , the refrigerator further includes a compressor 7 and a condenser 8, wherein the outlet of the compressor 7 is connected in series with the inlet of the condenser 8, and a three-way valve 9, wherein the outlet of the condenser 8 is connected to the inlet of the first evaporator 2 and the second evaporator 5 respectively via the three-way valve 9, so as to controllably realize the connection between the condenser 8 and the first evaporator 2 alone, the connection between the condenser 8 and the second evaporator 5 alone, or the connection between the condenser 8 and the first evaporator 2 and the second evaporator 5 at the same time.

As shown in combination with Figures 1 to 3, specifically, during the refrigeration process, the refrigerant flows from the compressor 7 to the condenser 8, and then flows to the three-way valve 9. The two outlets of the three-way valve 9 lead to the first evaporator 2 and the second evaporator 5 respectively, and the three-way valve 9 has three outlet states. Among them, one state is that the opening leading to the first evaporator 2 is opened, and the opening leading to the second evaporator 5 is closed, so that the refrigerant from the condenser 8 can only flow to the first evaporator 2, thereby refrigerating the first chamber 101. One state is that the opening leading to the second evaporator 5 is opened, and the opening leading to the first evaporator 2 is closed, so that the refrigerant from the condenser 8 can only flow to the second evaporator 5, thereby refrigerating the second chamber 102. One state is that the opening leading to the first evaporator 2 is opened, and the opening leading to the second evaporator 5 is opened, so that the refrigerant from the condenser 8 can flow to the first evaporator 2 and the second evaporator 5 respectively, thereby refrigerating the first chamber 101 and the second chamber 102 at the same time. That is, the first evaporator 2 and the second evaporator 5 share a compressor 7 and a condenser 8 , and the flow path of the refrigerant from the condenser 8 to the first evaporator 2 and the second evaporator 5 is adjusted by the three-way valve 9 .

By connecting the condenser 8 with the first evaporator 2 and the second evaporator 5 via the three-way valve 9, and adjusting the three-way valve 9, the condenser 8 can be connected with the first evaporator 2 alone to refrigerate the first chamber 101 alone, or connected with the second evaporator 5 alone to refrigerate the second chamber 102 alone, or connected with the first evaporator 2 and the second evaporator 5 at the same time to refrigerate the first chamber 101 and the second chamber 102 at the same time, so that the first evaporator 2 and the second evaporator 5 can be cooled separately even when they share a compressor 7 and a condenser 8, thereby simplifying the structure of the refrigerator while ensuring the refrigeration flexibility of the first chamber 101 and the second chamber 102.

It should be noted that, in some other embodiments, the first evaporator and the second evaporator may also correspond to separate compressors and condensers, respectively.

3 , the refrigerator further includes a first capillary tube 10 and a second capillary tube 11. The first capillary tube 10 is disposed between the first evaporator 2 and the three-way valve 9 so that the refrigerant flows through the first capillary tube 10 before flowing into the first evaporator 2. The second capillary tube 11 is disposed between the second evaporator 5 and the three-way valve 9 so that the refrigerant flows through the second capillary tube 11 before flowing into the second evaporator 5.

It should be noted that, in some other embodiments, the capillary tube may also be replaced by an expansion valve.

Furthermore, the flow rate of the second capillary tube 11 is greater than the flow rate of the first capillary tube 10. Through the above structural design, when the first evaporator 2 and the second evaporator 5 are refrigerating at the same time, more refrigerant can flow through the second evaporator 5, which helps to ensure the refrigeration effect of the magnetic field chamber.

1 to 3 , specifically, the compressor 7 and the condenser 8 are arranged at the bottom of the refrigerator, for example, at the lower left corner in FIG. 1 , that is, the first evaporator 2 is closer to the compressor 7 and the condenser 8, so that the path for the refrigerant to complete a full flow in the passage where the first evaporator 2 is located is shorter, and the second evaporator 5 is farther from the compressor 7 and the condenser 8, so that the path for the refrigerant to complete a full flow in the passage where the second evaporator 5 is located is longer. In this case, the flow rate of the second evaporator 5 is greater than the flow rate of the first capillary tube 10, so that more refrigerant flows through the farther second evaporator 5, and relatively less refrigerant flows through the closer first evaporator 2, which helps to ensure that both the first chamber 101 and the second chamber 102 can obtain a better refrigeration effect.

As shown in FIG. 3 , the first evaporator 2 is provided with two refrigerant channels, one of which is used to connect with the three-way valve 9, and the other is used to connect with the outlet end of the second evaporator 5, so that the refrigerant flowing out of the second evaporator 5 can flow through the first evaporator 2, and can provide some additional cooling capacity for the first evaporator 2. Specifically, when the first evaporator 2 and the second evaporator 5 are refrigerated at the same time, because the flow rate of the second capillary tube 11 is greater than the flow rate of the first capillary tube 10, more refrigerant flows from the three-way valve 9 to the second evaporator 5, and less refrigerant flows from the three-way valve 9 to the first evaporator 2. However, the refrigerant flowing through the second evaporator 5 will flow to the first evaporator 2, so as to use the remaining cooling capacity to cool the first evaporator 2. Therefore, although the refrigerant flowing through the first evaporator 2 is less, the refrigerant flowing through the second evaporator 5 additionally flows through the first evaporator 2, which helps to ensure the cooling effect of the first chamber 101. At the same time, because the first evaporator 2 is used to refrigerate the freezing chamber, that is, the first chamber 101, and the storage temperature required by the freezing chamber is particularly low, the refrigerant flowing through the second evaporator 5 also flows through the first evaporator 2, so that the first chamber 101 can be refrigerated while the second chamber 102 is refrigerated, which helps to maintain the low temperature of the first chamber 101 and reduce the frequency of the first chamber 101 reaching the start point, thereby reducing the compressor startup frequency and avoiding frequent start and stop of the compressor.

As shown in FIG2 , the refrigerator includes a turbulent fan 12, which is disposed in the second compartment 102 and is used to cause the air in the second compartment 102 to flow. Specifically, the turbulent fan 12 is disposed in the inner space of the second compartment 102. After the turbulent fan 12 is started, the turbulent fan 12 turbules the air in the second compartment 102, thereby making the cold energy more evenly distributed in the second compartment 102, and improving the temperature uniformity of the second compartment 102.

As shown in Fig. 2 and Fig. 4, further, the spoiler fan 12 is arranged at the top of the second chamber 102, and the air outlet of the spoiler fan 12 faces the top wall of the second chamber 102. Specifically, a mounting box 13 is provided near the top side wall of the second chamber 102, and the spoiler fan 12 is arranged in the mounting box 13. The bottom wall of the mounting box 13 is provided with an opening, and the surrounding side walls are also provided with openings. As shown by the arrow in Fig. 4, when the spoiler fan 12 is turned on, the spoiler fan 12 allows air to flow from bottom to top, and the airflow enters the mounting box 13 through the opening on the bottom wall of the mounting box 13, and then the spoiler fan 12 prompts the airflow to continue to flow upward, and the airflow is dispersed to the surroundings after hitting the top wall of the mounting box 13, and then flows out of the mounting box 13 through the openings around the mounting box 13 and continues to flow to the surroundings.

By arranging the turbulent fan 12 at the top of the second chamber 102 and making the air outlet of the turbulent fan 12 face the top wall of the second chamber 102, after the turbulent fan 12 is turned on, the turbulent fan 12 can cause the air in the second chamber 102 to flow from bottom to top, and the airflow will be blocked in the process of flowing upward, so that the airflow is diffused to the surroundings, and the cold is distributed more evenly in the second chamber 102. In addition, because the cold tends to be deposited at the bottom of the second chamber 102, the turbulent fan 12 makes the airflow flow from bottom to top, which helps to diffuse the cold deposited at the bottom of the second chamber 102 to the top of the second chamber 102, and better improves the temperature uniformity of the second chamber 102.

It should be noted that, in some other embodiments, the refrigerator may not be provided with a mounting box, and the spoiler fan is directly exposed in the second chamber.

1 and 2 , specifically, the magnetic field generating device 4 is a permanent magnet sheet. The permanent magnet sheet has a simple structure and is easy to install.

It should be noted that, in some other embodiments, the magnetic field generating device may be an electromagnetic coil; or, the magnetic field generating device may be a structure composed of a permanent magnet sheet and an electromagnetic coil.

2 , a temperature sensor 14 is further provided in the second chamber 102 . The temperature sensor 14 is used to detect the temperature of the second chamber 102 , so as to better control the refrigeration process of the second chamber 102 .

At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
