Household electrical appliance
[technical field]
The present invention relates to household electrical appliance, refer in particular to a kind of household electric refrigerator or refrigerator with the casing that is connected through the hinge and door.
[background technology]
Household electrical appliance, especially household electric refrigerator or refrigerator generally include the casing with inner accepting space and movably are connected to the door that is used to seal this inner accepting space on the casing, and door is hinged on the casing.Because the weight of door is big and switch is frequent, requires hinge to have good intensity, uses to satisfy for a long time.Simultaneously, people are attractive in appearance more and more higher to the household electrical appliance outward appearance, and it is hidden that this just requires that hinge will try one's best in casing and the installation site on the door, thereby avoid influencing the overall appearance aesthetic feeling of household electrical appliance.
United States Patent (USP) US7,065, disclosed a kind of household electric refrigerator 832B2 number, as shown in Figure 1 with hinge.This household electric refrigerator comprises casing 6, door 8, and hinge 32.One end of hinge 32 is fixed on by dog screw on the end face of casing 6, and the other end is inserted in the hole 12 on door 8 the end face.In order more firmly hinge 32 to be fixed on the end face of casing 6, in casing, can slip into a boss 18.This existing design no doubt can be satisfied the intensity of hinge and the firmly requirement of degree, but, because the two ends of hinge 32 all are to be directly installed on respectively on the last end face of casing 6 and door 8, no matter causing the user is front from refrigerator, or side from refrigerator, can be clear that the hinge of giving prominence on end face on casing 6 and the door 8, badly influence the aesthetic measure of the overall appearance of refrigerator, not meet the needs of current appliance design.

[specific embodiment]
With reference to figure 2, the refrigerator of one embodiment of the present invention comprises casing 1, door 2, and the hinge 3 that connects door 2 and casing 1.The casing 1 of the refrigerator of present embodiment has inner spatial accommodation, and this inside spatial accommodation comprises and being set up in parallel and refrigerating chamber spaced apart from each other and refrigerating chamber.Accordingly, door 2 comprises the refrigerating chamber of the difference closed box 1 that two fans are set up in parallel and the door body of refrigerating chamber, and Men Tijun can freely rotate between enable possition and closing position.The hinge 3 of present embodiment is arranged on casing 1 and door 2 top and is connected the upper hinge of door 2 and casing 1, extended meeting detailed description behind the structure of hinge 3 and the installation site.Usually also be provided with the following hinge that is connected door 2 and casing 1 in the bottom of casing 1 and door 2, show hinge down among the figure of present embodiment.
With reference to figure 3, hinge 3 of the present invention is made by the metal material with higher intensity and hardness, for example steel.Hinge 3 roughly is " L " type structure, and it comprises first end 31 and second end 34.The alignment pin 35 that downward extension is set on three locating holes, 32, the second ends 34 is set on first end 31.Between first end 31 and second end 34 groove 33 is set, the effect of groove 33 is to strengthen the tension compression strength of hinge 3.
With reference to figure 4, casing 1 of the present invention has top 10, and 10 sides near door 2 are provided with a depression 11 at the top.Depression 11 width is roughly the same with the width of first end 31 of hinge 3, and the degree of depth of depression 11 is less times greater than the thickness of first end 31 of hinge 3, thereby makes first end 31 of hinge 3 to be placed in to cave in 11.Locating hole 32 on first end 31 can match with the hold-down screw (not shown), thereby first end 31 of hinge 3 is fixed in the depression 11.Correspondingly, door 2 has top 20, and 20 sides near casing 1 are provided with a depression 21 at the top.Depression 20 width is provided with enough greatly, door 2 from full open position to complete closing position rotating process, second end 34 of hinge 3 not can with the sidewall interference of depression 21, guarantee door 2 freely rotating with respect to casing 1.Depression is provided with a locating hole in 21, and the alignment pin 35 on second end 34 of this locating hole and hinge 3 matches.After alignment pin 35 inserts this locating hole, be movable, guarantee door 2 freely rotating with respect to casing 1 with respect to this locating hole.
Because the top 10 of casing 1 is made by the sheet metal of very thin thickness usually, the bottom of depression 11 is made by the sheet metal of very thin thickness equally, and the weight of the door 2 that is connected with hinge 3 is bigger usually, cause caving in the undercapacity of this sheet metal of 11 bottoms securely first end 31 of hinge 3 is fixed in the depression 11, solution normally is provided with stiffening device in depression 11.With reference to figure 5 and Fig. 6, Fig. 5 and Fig. 6 have disclosed the reinforced sheet 4 of one embodiment of the present invention and have been installed in the position at the top 10 of casing 1.Reinforced sheet 4 has to have higher-strength and hardness and have certain thickness metal material makes two weld parts 41 that it comprises location division 40 and is positioned at 40 both sides, location division.Locating hole 32 corresponding through holes on first end 31 that has on the location division 40 with hinge 3, the hold-down screw (not shown) is passed locating hole 32 and is matched with this through hole, thereby first end 31 of hinge 3 is linked together with reinforced sheet 4.Weld part 41 is welded on the lower surface at top 10 of casing 1, thereby reinforced sheet 4 is positioned at the below of the depression 11 at top 10.
With reference to figure 7,, a hinged cover 4 is set on hinge 3 in order to make the outward appearance and my outward appearance of integral body of household electric refrigerator of hinge 3 after being installed between casing 1 and the door 2 more unified.Hinged cover 4 is made by plastic material, and the profile of its profile and hinge 3 is unanimous on the whole, also is " L " type.One end of hinged cover 4 is embedded in the depression 11 of casing 1 and covers on first end 31 of hinge 3, and another end cap is on second end 34 of hinge 3.
Fig. 2 is to the advantage of the refrigerator of scheming these 7 this embodiments that disclose: owing to be provided with first end 31 that can hold hinge 3 and the depression 11,21 of second end 34 respectively at the end face 10,20 of casing 1 and door 2, make hinge 3 be hidden in the depression 11,21, the user still is that the side all is not easy to see hinge 3 from the front, makes that the overall appearance of refrigerator is more attractive in appearance.Yet, it is to be noted, this is one embodiment of the present invention, those of ordinary skill in the art can make rational adjustment to this embodiment according to the principle of this embodiment, for example, the opening of the depression 11 of the casing 1 of present embodiment also can be adjusted on the leading flank that the top that opening is arranged on casing 1 faces the depression 21 on the door 2 on end face 10, and first end 31 of hinge 3 can insert from the recessed openings of this leading flank and navigated to the depression this moment; For example have, the reinforced sheet 4 of present embodiment navigates to the lower surface of end face 10 by welding, also can for example screw or riveted joint navigate to reinforced sheet the lower surface of end face 10 by other connected modes; These rational adjustment all should be within the protection domain of claim of the present invention.
