Description

TECHNICAL FIELD

[0001] The utility model relates to a refrigerator. BACKGROUND

[0002] A technology has been disclosed for a long time to charge dust and the like in air by using ion wind, finally adsorbing and collecting, realizing the effect of purifying air, thereby achieving the function of preservation, but the technology mainly realizes air purification of the refrigerator, and cannot realize the function of active sterilization of food materials in the refrigerator.

[0003] In order to realize the function of active sterilization of food materials in the refrigerator, the applicant proposes a technology of loading an ion generating device such as a nanometer ion generating device in the refrigerator. The nanometer ion generating device is a device that causes the condensed water on the surface of the refrigeration end to vibrate at a high frequency to generate atomization and ionize nanometer water ions by reducing the temperature of the surface of the refrigeration end to about -8 DEG C by semiconductor refrigeration and passing high-voltage current through the metal sheet installed below the semiconductor refrigeration end. Nanometer water ions are generated by the nanometer ion generating device, and bacteria and mold in the refrigerator are killed by the nanometer water ions to inhibit food spoilage and remove odors in the refrigerator, thereby playing a preservation role.

[0004] However, in the above technology, the overall sterilization and odor removal effect in the refrigerator is affected by the following technical problems: (1) the nanometer water ions have weak stability, with a half-life of 10 minutes, and the nanometer water ions are easily adsorbed on the surface of the evaporator when passing through the evaporator with low temperature, so the circulation speed of the air path in the refrigerator should not be too fast, otherwise the nanometer water ions are difficult to diffuse in the refrigerator, thereby reducing the circulation speed of the air path in the refrigerator; (2) the nanometer ion generating device is installed in the air path of the refrigeration chamber with low temperature (lower than 2 DEG C, for example, the average temperature is -1 DEG C), so that the overall temperature of the nanometer ion generating device is low, and the optimal temperature of the nanometer ion generating device is 2-8 DEG C, so that the condensed water on the surface of the refrigeration end of the nanometer ion generating device is easily frozen, and after freezing, the nanometer ion generating device cannot work normally, and enough nanometer water ions cannot be generated, thereby resulting in poor ion generation effect; (3) the air vent of the nanometer ion generating device is arranged on one side, thereby resulting in weak ion diffusion effect; (4) the nanometer ion generating device is installed in the left air path of the air path corresponding to the second refrigeration space of the refrigeration chamber, and the air path heat insulation foam is arranged at the front, the nanometer water ions enter the second refrigeration space through the air vent on one side and the left air vent of the second refrigeration space, thereby resulting in low nanometer water ion solubility in the first refrigeration space of the refrigeration chamber, and uneven distribution of ions in the refrigerator. SUMMARY

[0005] This utility model was made in view of the above-mentioned problems, and its purpose is to provide a refrigerator that can effectively improve the overall sterilization and odor removal effect of the refrigerator compartment.

[0006] To achieve the above objectives, the refrigerator of this invention includes a cabinet, a door, a compressor, a first evaporator, a first fan that draws in first cooling gas cooled by the first evaporator and sends it into a first compartment via a first air duct, and an ion generating device. A return air vent is provided at the bottom of the first compartment for the first cooling gas to return to the first evaporator. The ion generating device is located inside the first compartment, outside the first air duct. By placing the ion generating device inside the compartment and outside the air duct, the average temperature around the ion generating device is high and fluctuates less, ensuring the ion generating device is at a suitable temperature and preventing the semiconductor cooling end from freezing, which is beneficial for the normal operation of the ion generating device. This improves the ion generation effect. Furthermore, by placing the return air vent at the bottom of the first compartment, the refrigerator's air circulation is top-out and bottom-back, which allows ions to diffuse evenly within the compartment, improving ion uniformity. Therefore, the overall sterilization and odor removal effect within the refrigerator compartment can be effectively improved.

[0007] Alternatively, in the refrigerator described above, the cabinet may include an upper cabinet, a middle cabinet, and a lower cabinet, and the door may include an upper door and a lower door. The upper cabinet, the middle cabinet, and the upper door constitute the first compartment, and the lower cabinet and the lower door constitute the second compartment located below the first compartment. The first compartment includes at least a refrigerator compartment, and the second compartment is a freezer compartment.

[0008] Alternatively, in the refrigerator described above, the refrigerator compartment can be divided into multiple sections by partitions. The ion generating device is located in the uppermost first section of the refrigerator compartment, spaced a predetermined distance from the top vent where the cooling gas enters the first section. By placing the ion generating device in the uppermost first section and maintaining a predetermined distance from the top vent, direct cold airflow towards the ion generating device can be avoided, preventing a drop in ambient temperature and further enhancing the ion generation effect. Furthermore, the ion concentration within the first section of the refrigerator compartment is increased. This effectively improves the overall sterilization and odor removal effect within the refrigerator compartment.

[0009] In addition, in the refrigerator of the utility model, a cover plate is arranged in front of the ion generating device, and a plurality of through micro-holes are formed in the cover plate on both sides of the top air outlet when viewed from the front of the refrigerator. In this way, the ions can be blown into the chamber through the circulating micro-holes after being fully mixed with the cooling gas sent from the top air outlet, so that the ions can be uniformly blown into the chamber, the ion uniformity of the whole chamber is ensured, and the wind speed is reduced by arranging the circulating micro-holes, the time of ion retention in the chamber is prolonged, and the sterilization in the chamber is also facilitated. Therefore, the sterilization and odor removal effects in the whole chamber of the refrigerator can be further effectively improved.

[0010] In addition, in the refrigerator of the utility model, the refrigerator further comprises a second evaporator and a second fan for sucking the second cooling gas cooled by the second evaporator and sending the second cooling gas to the freezing chamber through a second air path.

[0011] In addition, in the refrigerator of the utility model, the first evaporator and the second evaporator are independently arranged. In this way, the temperature of the gas cooled by the first evaporator can be increased, and the temperature in the first chamber can be further increased to ensure that the ion generating device is at a more suitable temperature, so that the ion generating effect is further improved. Therefore, the sterilization and odor removal effects in the whole chamber of the refrigerator can be further effectively improved.

[0012] In addition, in the refrigerator of the utility model, the first chamber further comprises a constant-temperature chamber and a variable-temperature chamber located below the refrigerating chamber.

[0013] In addition, in the refrigerator of the utility model, the ion generating device comprises a shell, a power supply substrate is arranged in the interior of the shell, a semiconductor refrigeration end for generating condensed water on the surface, and a high-voltage ionization end for ionizing the condensed water into nanometer water ions, and a first air vent and a second air vent are formed on both sides of the high-voltage ionization end. In this way, the air vents are arranged on both sides of the high-voltage ionization end as the ion generating end, so that air circulation can be formed on both sides of the ion generating end, and the diffusion speed of the ions can be improved. Therefore, the sterilization and odor removal effects in the whole chamber of the refrigerator can be further improved.

[0014] In addition, in the refrigerator of the utility model, the compressor is arranged at the top of the refrigerator.

[0015] In addition, in the refrigerator according to the present application, the refrigerator can further comprise a defrosting water evaporation chamber arranged at the bottom of the refrigerator.

[0016] According to the present application, a refrigerator capable of effectively improving the sterilization and odor removal effects of the whole refrigerator compartment can be provided. BRIEF DESCRIPTION OF DRAWINGS

[0025] As Figure 1 and Figure 2As shown, the refrigerator 1 according to the present embodiment includes a cabinet 10, a door 20, a compressor 30, a first evaporator 40, a first fan 50, a nanoe ion generating device 60 as an example of an ion generating device, a second evaporator 70, and a second fan 80. In addition, the refrigerator 1 includes a first compartment SI, a second compartment S2 located below the first compartment SI, and a defrost water evaporation compartment S3 provided at the bottom of the refrigerator 1.

[0026] In the present embodiment, the cabinet 10 includes an upper cabinet 101, a middle cabinet 102, and a lower cabinet 103. The door 20 includes an upper door 201 and a lower door 202. In this way, the first compartment SI is formed by the upper cabinet 101, the middle cabinet 102, and the upper door 201, and the second compartment S2 is formed by the lower cabinet 103 and the lower door 202. Here, the first compartment SI includes a refrigerating compartment SI 1, a constant temperature compartment SI 2 located below the refrigerating compartment SI 1, and a variable temperature compartment SI 3 located below the constant temperature compartment SI 2, and the second compartment S2 is a freezing compartment. However, the first compartment can include at least the refrigerating compartment, and can not include at least either one of the constant temperature compartment and the variable temperature compartment.

[0027] In addition, the compressor 30 is provided at the top of the refrigerator 1. However, it is not limited thereto, and the compressor 30 can be provided at the bottom of the refrigerator 1.

[0028] The first fan 50 sucks the first cooling air cooled by the first evaporator 40 and supplies it to the first compartment SI via a first air passage PI. At the bottom of the first compartment SI, a return air port P2 is provided for the first cooling air to return to the first evaporator 40. In this way, the first cooling air, i.e., low-temperature air, cooled by the first evaporator 40 is sucked by the first fan 50, passes through the first air passage PI, and is blown into the first compartment SI from a top air port P4, a middle air port, and the like of the first compartment SI, and after cooling the first compartment SI, returns to the first evaporator 40 through the return air port P2, thereby forming a refrigerating air passage circulation.

[0029] The second fan 80 sucks the second cooling air cooled by the second evaporator 70 and supplies it to the freezing compartment S2 via a second air passage P3.

[0030] The nanoe ion generating device 60 is a device that generates so-called nanoe ions, i.e., nanometer water ions. As shown, the nanoe ion generating device 60 is provided in the first compartment SI and located outside the first air passage PI. Specifically, as shown, the nanoe ion generating device 60 is provided at the left side in the width direction of the first compartment SI. In addition, as an effect of the nanometer water ions, there are effects of killing bacteria and mold, and removing odors, and the like. Figure 2 Figure 1

[0031] ​​As a specific structure of the nano-ion generating device 60, as shown in Figure 3 the nano-ion generating device 60 includes a housing 601, a power supply substrate 602 arranged inside the housing 601, a semiconductor refrigeration end 603 for generating condensed water on the surface, and a high-voltage ionization end 604 for ionizing the condensed water into nano-water ions. In addition, the housing 601 is formed with a first air vent 605 and a second air vent 606 located on both sides (i.e., left and right sides) of the high-voltage ionization end 604. In this way, when the nano-ion generating device 60 is in operation, condensed water is generated on the working surface of the semiconductor refrigeration end 603, and when the high-voltage ionization end 604 is powered, the condensed water is ionized into nano-water ions and diffused through the first air vent 605 and the second air vent 606. When the first fan 50 is running, low-temperature air is blown out through the top air outlet P4 and dispersed by the cover plate 90. Part of the air flows through the first air vent 605 and the second air vent 606, carrying the nano-water ions, and is blown into the first chamber S1 through the circulating micro-holes. The nano-water ions flow back to the first evaporator 40 after being sterilized in the first chamber S1.

[0032] In addition, as shown in Figure 2 the refrigeration chamber S11 is divided into three refrigeration spaces by two partitions, i.e., a first refrigeration space S111 located at the uppermost part, a third refrigeration space S113 located at the lowermost part, and a second refrigeration space S112 located between the first refrigeration space S111 and the third refrigeration space S113.

[0033] The nano-ion generating device 60 is arranged in the first refrigeration space S111 and is spaced apart from the top air outlet P4 by a predetermined distance.

[0034] In addition, as shown in Figure 2 a cover plate 90 is arranged in front of the nano-ion generating device 60. In addition, as shown in Figure 1 a plurality of through micro-holes 901 are formed in the cover plate 90 on both sides of the top air outlet P4 when viewed from the front of the refrigerator 1.

[0035] In this embodiment, the ion generating device is arranged in the chamber and located on the outer side of the air path, so that the average temperature around the ion generating device is high and the fluctuation is small, which can ensure that the ion generating device is at a suitable temperature and the semiconductor refrigeration end is not easy to freeze, which is beneficial to the normal operation of the ion generating device, thereby improving the ion generating effect. In addition, the return air outlet is arranged at the bottom of the first chamber, so that the air circulation of the refrigerator is from the top air outlet and the bottom return air outlet, thereby enabling the ions to diffuse uniformly in the chamber, and the uniformity of the ions in the chamber is improved. Therefore, the overall sterilization and odor removal effect in the chamber of the refrigerator can be effectively improved.

[0036] In addition, the ion generating device is arranged in the first refrigerating space at the uppermost portion and is spaced apart from the top air outlet by a predetermined distance, so that cold air is prevented from being directly blown to the ion generating device to lower the temperature of the surroundings, the ion generating effect is further improved, and the ion concentration in the first refrigerating space is increased. Thus, the sterilization and odor removal effects in the entire refrigerator compartment can be further effectively improved.

[0037] In addition, the through micro-holes are formed on the left and right sides of the cover plate, so that the ions are blown into the compartment through the circulating micro-holes after being sufficiently mixed with the cooling gas sent from the top air outlet. Thus, the ions can be uniformly blown into the compartment, the ion uniformity of the entire compartment is ensured, and the wind speed is reduced by the circulating micro-holes, the ions stay in the compartment for a longer time, and the sterilization in the compartment is also facilitated. Thus, the sterilization and odor removal effects in the entire refrigerator compartment can be further effectively improved.

[0038] In addition, the through micro-holes are formed on the left and right sides of the cover plate, so that the ions are blown into the compartment through the circulating micro-holes after being sufficiently mixed with the cooling gas sent from the top air outlet. Thus, the ions can be uniformly blown into the compartment, the ion uniformity of the entire compartment is ensured, and the wind speed is reduced by the circulating micro-holes, the ions stay in the compartment for a longer time, and the sterilization in the compartment is also facilitated. Thus, the sterilization and odor removal effects in the entire refrigerator compartment can be further effectively improved.

[0039] In addition, in the embodiment, the first evaporator 40 and the second evaporator 70 are independently arranged. In this way, the temperature of the gas cooled by the first evaporator can be increased, and the temperature in the first compartment can be further increased to ensure that the ion generating device is at a more suitable temperature, so that the ion generating effect is further improved.
