Abstract

A multipurpose refrigerator is disclosed, which can change the opening and shutting door to opaque or transparent for home or commercial use as needed. In front of the refrigerator (N), opening and shutting doors (1, 2) are installed and they can be rotating open or rotating closed by the rotating support axes (N1a, N2a) at the top and the bottom of the refrigerator (N). The opaque door (1) is attached in front of the transparent door (2), and by inserting rotating axis balls (102, 103, 202, 212) at the top and the bottom of the refrigerator (N) into rotating support axes (N1a, N2a) the opaque door (1) and the transparent door (2) can be rotated independently. The rotating axis balls (202, 212) are either attachable or detachable from the rotating support axes (N1a, N2a) by making joint part (203), which will touch the switch (3) on the cover (10) of the refrigerator and quirks (201, 211), which connect to the rotating axis balls (202, 212) at one part of the rotating axis balls (202, 212) at the top and the bottom of the opaque door (2).

Description

A MULT IPURPOSE REFR IGERATOR

TECHN ICAL F IELD

The Invention described here is a multipurpose refrigerator. In front

of the refrigerator, a transparent opening and shutting door and an

opaque opening and shutting door are installed in order. They can be

rotating open or rotating shut. The outer opaque door can be attached 01

detached. If you take off the door, you can use it for commercial

pui pose On the othei hand, if you use the refrigerator as it is, it would

function as an excellent thermal insulating multipurpose refrigerator.

BACKGROUND ART

In general, the categorization of home use and commercial use is

based on its appearance, but the opening and shutting door can make a

different category based on the usage and purpose of using it. That is to

say. the opening and shutting door of the home use refrigerator is

opaque in general, so the content of it can not be seen from outside

On the othei hand, the opening and shutting door of commercial

refngerator is transparent because it needs a display effect. So up to

now, there has been a problem which restricts the purpose of

refrigerator use just because of the difference of an opening and shutting D ISCLOSURE OF INVENT ION

As I described above, to solve the previous problem and

inconvenience at the same time, we invented a multipurpose refrigerator

which has a transparent door and an outer opaque door so that users

can put it on or take it off according to the place they use it(home or

store etc.) . This is quite an invention with many benefits. It expands the

range of usage, because only by putting on or taking off the opaque

opening and shutting door(2) outside of the transparent doorO ) , you can

convert the usage of the refrigerator(N) between home use and

commercial use. When you use it as a home use, you can identify the

content, whether it is there or where it is, before taking it out from the

refrigerator, so you can keep the storage for much longer time.

BEST MODE FOR CARRY ING OUT THE INVENTION

Installing the opening and shutting door at the front of a

refrigerator and making it rotating open and rotating close by the top and

bottom rotating support axes(N1 a, N2a), we built the opening and shutting door of the refrιgerator(N) double with

one transparent door(1 ) and one opaque door(2), and then inserted the

rotating axis ballsO 02, 103,202,212) at the top and bottom of each

opening and shutting doors(1 ,2) into the projected rotating support

axes(N 1 a,N2a) at the top and bottom support parts(N 1 ,N2) of

refrιgerator(N) so that the transparent opening and shutting doorO ) and

opaque opening and shutting door can be independently rotated, yet

making the opaque door(2) outer door that can be attached or detached

at the front of the transparent doorO ) by the joint parts(203,213) that

have quιrks(201 ,21 1 ) which are wide outside and narrow inside and

connected to the rotating axis balls(202,212) at the top and the bottom

of the opaque opening and shutting door(2)

And there are button swιtches(3) and press parts(4) that can be

generally used at the top coverd O) of the refrigerator The button

switch(3) will be switched off by the intervention of joint part(203) at the

top of the opaque opening and shutting door(2) when the door(2) is

closed, and will be back on if the intervention is removed That is the

way to control the inner light of the refrιgerator(N)

Also, by attaching a packing(101 ) same as the one installed

between the transparent doorO ) and refrigerator at the girth between an

opaque door(2) and a transparent doord ), we made the refπgeratoi

perfectly tightly shut and more heat insulated On the other hand the packingd OI ) has rubber magnetic inside, so the opaque doord ) can be

smoothly open and shut and is kept from opening by accident,

On the drawing, the code 20 which has no description is the

handle of each doorsd ,2) and 30 denotes a shelf which will be put into

the refrigerator

Just like described, the invention has a transparent opening and

shutting doord ) and opaque opening and shutting door(2) installed

two-fold

The opaque one(2) can be attached and detached at the rotating

support axes(N 1 a,N2a) because the rotating axis balls(202,212) at the top

and the bottom of the opaque door(2) are based on the quιrks(201 21 1 )

on one side

In other words, the opaque door(2) can be attached or detached at the

front of the refπgerator(N) , We can get a commercial refπgerator(N) which

shows the storage inside when we detach the opaque door(2) at the

outside of the transparent doord ) or we would have a home

refπgerator(N) whose content can not be seen through from outside

Because each doors inside or outside can be rotating open or rotating

closed if you open the outside opaque door(2) only, you can see the

storage inside without exposing the refrιgerator(N)

The joint part(203) at the top of the opaque door(2) will touch the top

coverd O) of the refπgerator(N) and will be pressed down when the opaque door(2) is closed, which will turn off the light in the

refrigerator(N) . On the contrary, it will be popped up when the opaque

door is being opened and will operate the button switch(3) which turn off

the light.

Because the opaque door(2) will be removed when the refrigerator

is used as commercial, the light might be always turned on. There is an

auxiliary press part(4) at the side of button switch(3), and you can turn

the light off by making the press part(4) push down the button switch(3).

We attached a packingd OI ) around the inside girth of the opaque

door to absorb shock, double heat insulation and for the ease of opening

and closing. This is the same rubber as the one installed in the

refrigerator and the packing has a rubber magnetic inside which makes

the opening and shutting of the door easy.

We also made grooves at the front of the opaque door, so you

can express beautiful pictures on it.

You can selectively put in or take out shelves inside of the

transparent doord ) when you use it at home, because inside of the

transparent doord ), there are hooking grooves at each sides. It is a

general structure for the refrigerator, so we will omit the detail for it.

The refrigerator in our description includes general refrigerators with

a cold storage and a freezer, or cooling only or freezing only devices as

well.
