Description

REFRIGERATOR AND ION GENERATOR ASSEMBLY THEREOF

FIELD OF THE INVENTION

The present invention relates to a refrigerator deodorization field, and more especially to a refrigerator and an ion generator assembly thereof.

BACKGROUND ART

Generally speaking, a refrigerator is an appliance for maintaining foods stored therein under a low-temperature environment. Here is the common working principle of the refrigerator: during the evaporating process in a cooling machine, the refrigerant that is compressed in a compressor will absorb heat from the ambient air, so as to reduce the temperature of the ambient air. Moreover, air cooled during the above process is directed from the backside of the freezing compartment and the refrigerating compartment to their front by means of blowing action of a circulation fan arranged at the back of the freezing compartment and the refrigerating compartment, to maintain the temperature required by the foods in the freezing compartment or in the refrigerating compartment, such that the foods stored in the freezing compartment and the refrigerating compartment can be kept at a fresh condition for long time. Thereby, to elongate the storage time of foods, the various foods will be stored in the freezing compartment or refrigerating compartment of the refrigerator according to use requirements, so as to prevent the foods from

deteriorating and prevent reduction in the fresh degree. In this way, the refrigerator can store the various foods for long time.

Different from the freezing compartment for freezing foods, the refrigerating compartment is to store the foods at a temperature above the freezing point. Moreover, the refrigerating compartment also needs to store such foods that have been cooked well or have dense odor such as pickles for long time, and thus a user will be annoyed by the odor generated during the storing process of the foods. At present, in the domestic refrigerator, in order to reduce the odor generated by the various foods and prevent the odor from penetrating into other foods, platinum catalyst is usually arranged at the side of a defrost heater. In addition, in the recent domestic refrigerator, coolers are provided for cooling the freezing compartment and the

refrigerating compartment respectively, and the refreshing effect is enhanced by increasing the temperature in the refrigerating compartment. However, increase of the temperature in the refrigerating compartment will easily generate the stench, and easily breed the mixed bacterium in the refrigerating compartment.

For this reason, the active carbon is usually used in the refrigerator, and the various odors in the refrigerator are eliminated by means of the absorbing ability of the active carbon. Although this solution is relatively simple, the ideal sterilization and air purification effects can not be achieved due to limitation of the absorbing ability of the active carbon itself.

Now, there is a keen desire for a refrigerator deodorizing appliance that can fundamentally meet the sterilization and deodorization needs.

SUMMARY OF THE INVENTION

In view of this, the present invention is to provide a refrigerator and its ion generator assembly, to realize sterilizing and deodorizing effects fundamentally.

DETAILED DESCRIPTION OF THE INVENTION

The present invention is to provide a refrigerator and its ion generator assembly, to realize the sterilizing and deodorizing effects fundamentally.

The main inventive concept of the present invention is to arrange an ion generator within the refrigerating compartment of the refrigerator, and the ion generator can generate ozone ions by electrolyzing air molecules to exterminate the bacterium in the air in the refrigerator, thereby fundamentally realizing the sterilizing and deodorizing effects.

Hereinafter, technical solutions of the present invention will be described clearly and completely in combination with the drawings. Obviously, the mentioned embodiments are only parts in the present invention, rather than all the embodiments. Based on the mentioned embodiments in the present invention, any other embodiments that the person skilled in the art can reach under the premise of not exercising the creative skill shall fall into the scope of protection of the present invention.

Referring to Figs. 1 and 2, Fig. 1 is a bottom view of the ion generator assembly provided in the embodiment of the present invention, and Fig. 2 is a top view of the ion generator assembly provided in the embodiment of the present invention. The ion generator assembly as provided by the present invention can be used for carrying out refreshing and deodorizing treatments for the refrigerating compartment of the refrigerator, thereby achieving the ideal sterilizing and air-purifying effects. The ion generator assembly comprises: an ion generator base 1 , an ion generator 3 and an ion generator cover 2, wherein the ion generator 3 has ion emission electrodes 31 a, 31 b and a power plug 32, which is used to be connected with a power supply and supply the ion generator 3 with power. There are two ion emission electrodes, namely a first ion emission electrode 31a and a second ion emission electrode 31 b. When the power plug 32 is connected to the power supply, the ion generator 3 boosts the power frequency voltage to a required voltage by means of a high-voltage transformer, and the first ion emission electrode 31a and the second ion emission electrode 31 b ionize air into ozone ions. The ozone ions have the function of exterminating the bacterium, and thereby the sterilizing and deodorizing effects can be realized fundamentally.

As shown in Fig. 1 , the ion generator base 1 is provided with a limiting groove 17 for accommodating the ion generator 3, and fixing jacks (a first fixing jack 12a, and a second fixing jack 12b) for mounting the ion emission electrodes (the first ion emission electrode 31a and the second ion emission electrode 31 b). The ion generator 3 is disposed in the limiting groove 17. The fixing jacks are through-holes, and the first ion emission electrode 31a and the second ion emission electrode 31 b are inserted into and protrude from the first fixing jack 12a and the second fixing jack 12b respectively.

There may be a plurality of fixing jacks. In this embodiment, the number of the fixing jack is four, and a distance between the first ion emission electrode 31a and the second ion emission electrode 31 b can be varied by means of fitting of the first and second ion emission electrodes 31a, 31 b into the different fixing jacks, so as to be adapted to the ion generators 3 of different sizes. The persons skilled in the art can understand that since there are only two electrodes, only two fixing jacks just can meet the requirement (namely the first fixing jack 12a and the second fixing jack 12b).

As shown in Fig. 2, the ion generator cover 2 is fitted on the ion generator base 1 , and disposed above protruding end surfaces of the ion emission electrodes. A pierced structure is formed at a position of the ion generator cover 2 opposite to the ion emission electrodes. Concretely speaking, the ion generator base 1 is provided with an assembling end surface that is to be fitted to an inner container of the refrigerator. The ion generator cover 2 is fitted on the other end surface of the ion generator base 1 opposite to the assembling end surface, namely the protruding end surfaces of the ion emission electrodes (the first ion emission electrode 31a and the second ion emission electrode 31b) after being inserted into the fixing jacks. A pierced structure 21 is formed at a position of the ion generator cover 2 corresponding to the fixing jacks of the ion generator base 1 equipped with the ion emission electrodes, so as to ensure that the ozone ions can flow out through the pierced structure. Since the ion generator 3 needs to work under high voltage, arrangement of the ion generator cover 2 can achieve a protection function, and avoid the danger caused by accident touch of hands.

When placing the above ion generator assembly in the refrigerating compartment of the refrigerator, the ion generator can generate ozone ions by ionizing air molecules to exterminate the bacterium in the air in the refrigerator, and thereby the sterilizing and deodorizing effects can be fundamentally realized. If the ion generator assembly is arranged at the air duct outlet of the refrigerating compartment, the ozone ions generated by ionization can be taken to each corner of the refrigerating compartment to the maximum extent, and thereby everywhere is sterilized. The ion generator assembly is provided with the ion generator cover 2, and moreover an air duct cover plate is disposed outside the air duct of the refrigerator. Thereby, the ion generator can be disposed at a place that is inaccessible to the hands, and safety of a user is ensured, and

simultaneously the overall appearance effect in the refrigerator will not be influenced. The ion generator base provides a mounting basis for the ion generator, and a mounting basis for mounting the whole ion generator assembly in the refrigerating compartment of the refrigerator. By means of the ion generator base, the ion generator assembly can be conveniently mounted on the inner container of the refrigerating compartment of the refrigerator.

To achieve more reliable fixation of the ion emission electrodes, the ion generator assembly of the present invention further comprises an electrode fixing support plate 11 , which has inserting columns adapted to fit with the fixing jacks (the first fixing jack 12a and the second fixing jack 12b). The number of the inserting columns is the same as that of the ion emission electrodes, namely having a first inserting column 11a and a second inserting column 1 1 b. Both the first inserting column 1 1a and the second inserting column 11 b are provided with jacks adapted to fit with the ion emission electrodes. The first ion emission electrode 31a and the second ion emission electrode 31 b are respectively inserted into the jacks of the first inserting column 11 a and the second inserting column 11 b, and then the first inserting column 11 a and the second inserting column 1 1 b are respectively inserted into the first fixing jack 12a and the second fixing jack 12b. The electrode fixing support plate 11 may have threaded holes for fixing the electrode fixing support plate 11 to the ion generator base 1 by bolts, so as to achieve reliable fixation of the first ion emission electrode 31a and the second ion emission electrode 31 b, and to avoid a disadvantage that the ozone ions can not diffuse out smoothly due to escape of the first ion emission electrode 31a and the second ion emission electrode 31 b from the first fixing jack 12a and the second fixing jack 12b.

Referring to Figs. 3-5, Fig. 3 is a structural schematic view of a bottom of the ion generator cover provided in the embodiment of the present invention, Fig. 4 is a structural schematic view of a top of the ion generator base provided in the embodiment of the present invention, and Fig. 5 is an assembling schematic view of the ion generator cover and the ion generator base provided in the embodiment of the present invention.

As shown in Fig. 3, the ion generator cover 2 is provided with three fixing hooks in a triangle arrangement, namely a first fixing hook 23a, a second fixing hook 23b and a third fixing hook 23c; and correspondingly, as shown in Fig. 4, the ion generator base 1 is provided with three clip slots adapted to fit with the three fixing hooks, namely a first clip slot 14a, a second clip slot 14b and a third clip slot 14c. As shown in Fig. 5, cooperation of the three fixing hooks and the three clip slots achieves the fixation of the ion generator cover 2 and the ion generator base 1. Top ends of the fixing hooks are provided with hook-like bodies, and after the fixing hooks pass through the clip slots, the hook-like bodies will hook over tops of the clip slots, thereby fixing together the ion generator cover 2 and the ion generator base 1. In this embodiment, arrangement of the three fixing hooks and the three clip slots is a preferred fixing manner, and the person skilled in the art can understand that only two mutually-fitted fixing hooks and clip slots can achieve their fixation. Since the triangle is of stability, use of the three mutually-fitted fixing hooks and clip slots can make the fixation of the ion generator cover 2 and the ion generator base 1 more stable and reliable.

The ion generator cover 2 is further provided with positioning bolts, and there are two positioning bolts in this embodiment, namely a first positioning bolt 22a and a second positioning bolt 22b (as shown in Fig. 3). Correspondingly, the ion generator base 1 is further provided with positioning portions, and there are also two positioning portions in this embodiment, namely a first positioning portion 13a and a second positioning portion 13b (as shown in Fig. 4). One end of the positioning portion close to the ion generator cover 2 is a positioning hole adapted to fit with the positioning bolt (Fig. 5 shows a positioning hole 131 b of the second positioning portion 13b), and the opposite end is a positioning column (Fig. 5 shows a positioning column 132b of the second positioning portion 13b). Both the positioning bolts and the positioning portions are provided with jacks allowing screws to pass through. The first positioning bolt 22a and the second positioning bolt 22b are respectively inserted into the positioning holes of the first positioning portion 13a and the second positioning portion 13b, and by means of cooperation of the positioning bolts and the positioning holes, the relative position of the ion generator cover 2 and the ion generator base 1 can be easily determined. When assembling the ion generator cover 2 onto the ion generator base 1 , it is only required to align and insert the first positioning bolt 22a and the second positioning bolt 22b on the ion generator cover 2 respectively with and into the positioning holes of the first positioning portion 13a and the second positioning portion 13b on the ion generator base 1 , and in this way, the ion generator cover 2 can be assembled onto the correct position on the ion generator base 1. This shortens the assembling time and enhances the assembling efficiency.

Besides the above function, the positioning bolt and the positioning portion have also the function of determining a positional relation of the ion generator assembly and the refrigerator. Limiting holes are arranged at corresponding positions within the refrigerating compartment of the refrigerator, and when assembling the ion generator assembly, the positioning columns on the ion generator base 1 are inserted into the limiting holes of the refrigerator, so as to determine the positional relation of the ion generator assembly and the refrigerator. Moreover, both the positioning bolts and the positioning portions are provided with the jacks allowing screws to pass through. The screws are made to pass through the jacks and are tightened on the limiting holes, and in this way, the ion generator cover 2 and the ion generator base 1 are assembled onto the refrigerator.

Referring to Figs. 6 and 7, Fig. 6 is an exploded view showing that the ion generator of the ion generator assembly is not assembled to the ion generator base provided in the embodiments of the present invention, and Fig. 7 is a structural schematic view after the ion generator of the ion generator assembly is assembled to the ion generator base provided in the embodiments of the present invention.

As shown in Fig. 6, the ion generator 3 is to be assembled into the limiting groove 17 of the ion generator base 1. In order to achieve fixation of the ion generator 3, at least one pair of the opposite sidewalls of the limiting groove 17 is provided with hooks for fixing the ion generator 3, namely a first hook 15a and a second hook 15b. The so-called one pair of the opposite sidewalls specifically refers to: one sidewall, and one sidewall opposite to this side wall. After assembling the ion generator 3 into the limiting groove 17, the hook-like bodies at tops of the first hook 15a and the second hook 15b will hook end faces of a top of the ion generator 3, so as to prevent a disadvantage that the ion generator 3 moves due to a slight external force or vibration.

As shown in Fig. 7, both ends of the ion generator 3 may also be provided with positioning lugs, which have screw holes allowing screws to pass through. After the ion generator 3 is assembled to the limiting groove 17, the screws are used to pass through the screw holes on the positioning lugs, and by means of thread fitting of the screw holes and the screws, the screws are tightened, until the hook-like bodies at the tops of the first hook 15a and the second hook 15b are brought into contact with the end faces of the top of the ion generator 3. After the screws are tightened, the screws will exert an upward acting force on the ion generator 3, while the first hook 15a and the second hook 15b exert a downward acting force on the ion generator 3, whereby tightly fixing the ion generator 3 by means of the upward and downward acting forces. By arranging the positioning lugs at both ends of the ion generator 3, the error requirement between the height of the hook-like bodies of the first and second hooks 15a, 15b and the height of the ion generator 3 can be reduced. Even if the height of the hook-like bodies of the first and second hooks 15a, 15b is greater than the height of the ion generator 3, fixation of the ion generator 3 can also be achieved by tightening the screws, so long as the screws are ensured to enough long.

After the ion generator 3 is assembled well, the first and second ion emission electrodes 31a, 31 b are respectively inserted into the jacks on the first inserting column 1 1a and the second inserting column 1 1 b of the electrode fixing support plate 1 1 , and then the first inserting column 1 1a and the second inserting column 1 1 b are respectively inserted into the first fixing jack 12a and the second fixing jack 12b on the ion generator base 1 , whereby completing the assembling of the two electrodes. Fig. 7 shows four fixing jacks, and this is arranged according to the two different types of the ion generator 3 in the present invention. With respect to the ion generator of relatively high power, the two electrodes are respectively inserted into the two fixing jacks at both ends in order to ensure a sufficient space between the two electrodes; and with respect to the ion generator of relatively low power, the two electrodes are respectively inserted into the two fixing jacks at the middle. The ion generator base 1 in the present invention is suitable for installing of two different types of the ion generators. The person skilled in the art can appreciate that more fixing jacks can be provided to be adapted to more types of ion generators.

Activation of the ion generator 3 needs power of an external power supply. Thereby, the power plug 32 and a power line 18b connected to the power plug 32 are needed to introduce electric current into the ion generator 3, and then power lines 18a are used for introducing electric current into the first ion emission electrode 31a and the second ion emission electrode 31 b, so as to complete the ionization operation. Since these power lines are twisted together on the ion generator base 1 , clamp boards are disposed on the ion generator base 1 in order to clear up the power lines. The clamp boards have clip slots thereon for receiving exposed power lines of the ion generator 3, and arrangement of the power lines can be achieved by the clip slots on the clamp boards.

As illustrated in Fig.6, in this embodiment, there are a first clamp board 16a, a second clamp board 16b, and a third clamp board 16c, wherein the clip slots of the first clamp board 16a and the second clamp board 16b are used for accommodating the two power lines introduced from the ion generator 3 to the first ion emission electrode 31 a and the second ion emission electrode 31 b respectively, and the clip slot of the third clamp board 16c is used for accommodating the power line connected to the power plug 32.

Referring to Figs. 8 and 9, Fig. 8 is a structural schematic view of mounting the ion generator assembly provided in the embodiment of the present invention in a refrigerator; and Fig. 9 is a sectional view showing that the ion generator assembly provided in the embodiment of the present invention is in the refrigerator.

The present invention also provides a refrigerator, which comprises a refrigerating compartment, wherein an assembling groove 101 is disposed at an air duct outlet of the refrigerating compartment (the air duct outlet is usually opened on the inner container of the refrigerating compartment). The above-mentioned ion generator assembly 102 having the ion generator 3 and an air duct cover plate (not shown) disposed outside the ion generator assembly 102 are disposed in the assembling groove 101.

As shown in Fig. 9, in order to meet positioning and assembling needs of the ion generator assembly and the refrigerator, on the assembling groove 101 of the refrigerator a limiting hole 101 1 is provided which is adapted to fit with the positioning column 132 on the ion generator base 1 of the ion generator assembly. When assembling the ion generator assembly, an assembling end face of the ion generator base 1 is made to face the assembling groove 101 of the refrigerator, and the positioning column 132 on the ion generator base 1 is inserted into the limiting hole 1011 on the refrigerator, so as to determine the positional relation between the ion generator assembly and the refrigerator. Moreover, both the positioning bolts on the ion generator cover 2 and the positioning portions are provided with jacks 133 allowing screws to pass through. The screws are made to pass through the jacks 133 and are tightened on the limiting hole 101 1 , and in this way, the ion generator cover 2, the ion generator base 1 , and the refrigerator are assembled together.

Thereby, by disposing the ion generator assembly at the air duct outlet of the refrigerating compartment, the ozone ions generated by ionization can be taken to each corner of the refrigerating compartment to the maximum extent by means of cold wind, and thus everywhere is sterilized. The ion generator assembly is provided with the ion generator cover, and moreover the air duct cover plate is disposed outside the air duct of the refrigerator. Thereby, the ion generator can be disposed at a place that is inaccessible to the hands, and safety of a user is ensured, and simultaneously the overall appearance effect in the refrigerator will not be influenced. The ion generator base provides a mounting basis for the ion generator, and a mounting basis for mounting the whole ion generator assembly in the refrigerating compartment of the refrigerator. By means of the ion generator base, the ion generator assembly can be conveniently mounted on the inner container of the refrigerating compartment of the refrigerator.
