Description

Door / Window Attachment Refrigerator {REFRIGERATOR ATTACHABLE TO GATE / WINDOW}

The present invention relates to a refrigerator, and more particularly to a refrigerator that can be installed in a door or a window.

A refrigerator is a device that cools a predetermined refrigerator compartment and a freezer compartment formed therein and stores food in the refrigerator / freezer for a long time freshly. The cooling operation of the refrigerator is generally performed by first cooling the ambient air by latent heat of evaporation generated upon expansion of the refrigerant and then circulating the cooled air by the blowing means.

However, these conventional refrigerators have a problem in that the installation location and use range are limited due to their structural characteristics.

In more detail, a typical refrigerator requires various accessories such as a compressor, an evaporator, and the like, and a space for them due to a cooling method using a refrigerant. Because of this, there is a limit to the minimization and simplification of the conventional refrigerator and it is often impossible to install in a specific location.

Milk or yogurt, for example, is generally delivered through the main newspaper slot. However, when leaving home for a long period of time due to going out or traveling, the delivered foods are easily damaged, especially in summer, because they are stored at room temperature. Here, there is a need for a refrigerator that can keep fresh foods installed and delivered to the door, but the development is not easy due to the size and structural limitations described by Arthur.

The present invention has been made to solve the above-mentioned problems, an object of the present invention is to provide a refrigerator that can be used directly attached to a location connecting the inside and the outside, such as a door or window.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention in which the above objects can be specifically realized are described with reference to the accompanying drawings. In describing the present embodiment, the same name and the same reference numerals are used for the same configuration and additional description thereof will be omitted below.

1 is a cross-sectional view showing a first embodiment of a refrigerator according to the present invention, Figure 2 is a cross-sectional view of a second embodiment of the refrigerator according to the present invention. The configuration of the present invention will be described in detail with reference to these drawings.

First, the first embodiment of the present invention is a refrigerator attached to the main door 1, the body 10 is largely attached to the main door 1, the cooling device 20 installed in the body 10 and The body 10 is composed of a door 30 for opening and closing the storage compartment inside.

In the configuration of the door-attached refrigerator, the body 10 is formed in the inner case 11 which is spaced at a predetermined interval from the outer case 11 and the outer case 11 to form the overall appearance of the refrigerator as a whole. ). Here, the inner case 12 is made of a thermally conductive material, and a metal material such as aluminum may be used as the thermally conductive material. The inner case 12 forms a storage compartment 13 inside the body 10, and the storage compartment 13 has a predetermined size formed at the front of the body 10 by the external / inner cases 11 and 12. Through the opening 13a, it communicates with the main door 1, more specifically with the inlet 2 formed in the main door. Apart from this, an inner partition 11a is installed at a rear portion of the body 10, and the partition 11a forms an internal device chamber 15 having a predetermined size for accommodating the cooling device 20. The space between the outer / inner cases 11 and 12 and the inner partition 11a is filled with a heat insulating material 14 to keep the temperature in the storage chamber 13 constant.

On the other hand, the body 10 may be attached to the door (1) using a variety of fixing members, but it is preferable to use an electromagnet located in front of the body 10 as the fixing member. The electromagnet 16 may be stably attached to the refrigerator to the gate mostly made of iron when power is applied.

In the constitution of the present invention, the cooling device 30 is required to maintain the inside of the storage chamber 13 at a predetermined low temperature in order to keep the food stored basically. In addition, in order to be lightweight and simplified so that the refrigerator can be directly attached to the window, the cooling device 30 itself is required to be small and high efficiency.

To this end, a direct cooling method using a thermoelectric module is applied to the cooling device 30 of the present invention. Accordingly, the cooling device 30 is spaced apart from the thermoelectric element 21 having the heat absorbing portion attached to the inner case 12, the heat sink 21 attached to the heat generating portion of the thermoelectric element 21, and the heat sink 21. It comprises a fan (23) which is installed to be.

The thermoelectric element 21 is formed of a thermoelectric element formed by stacking N-type and P-type semiconductors, an electrode bonded to upper and lower portions of the thermoelectric element, and a ceramic substrate attached to surround the electrodes, respectively. The thermoelectric element 21 uses the Peltier effect, which is a phenomenon in which a temperature difference occurs between two end surfaces of different metals when electricity is basically applied to two different metals joined together.

That is, when a direct current is applied to the positive electrode of the thermoelectric element 21, electrons in the N-type semiconductor and holes in the P-type semiconductor move from one side to the other side, take away the heat of one side and release it to the other side. Therefore, both side surfaces of the thermoelectric element 21 are respectively a heat absorbing portion and a heat generating portion that act independently. In the present invention, as described above, the heat absorbing portion of the thermoelectric element 21 is in close contact with the thermally conductive inner case 12, and thus, the inner case 12 and the internal storage chamber 13 may operate in the thermoelectric element ( Direct cooling by heat conduction from 21).

In addition, in the thermoelectric element 21, the endothermic portion is heated by its own heat transfer from the heat generating portion when left in operation due to its characteristics. Accordingly, in order to improve the heat absorbing part performance (cooling performance), a heat sink 22 and a fan 23 which appropriately cool the heat generating part are used. Here, the heat sink 22 generally has an air-cooled fin structure as shown, but a water-cooled structure may be used to obtain higher cooling performance. The fan 23 cools the heat sink 22 by blowing air introduced through the through hole 11b formed in the body 10.

In the configuration of the present invention, the door 30 is hinged to the storage compartment 13 and includes an elastic member installed on the hinge to support the body of the door 30. Accordingly, when the person who delivers from the outside pushes the food through the inlet 2 of the main door 1, the door 30 rotates about the hinge so that the internal storage chamber 13 is opened, and the food is stored. Thereafter, the internal storage chamber 13 is closed to prevent cold air leakage by the restoring force of the elastic member.

This first embodiment can be applied to a position other than the door 1 connecting the house and the outside to accommodate the food to be delivered due to the nature of the construction. Accordingly, the second embodiment of the present invention has a structure that can be attached to the window 4 formed in the wall 3 of the house, and is relatively large in size compared to the first embodiment, that is, the window 4. Have a size that fits.

In more detail, as shown in FIG. 2, the second embodiment also has a body 10 that is in close contact with the window 4 and cooling installed inside the body 10, similarly to the first embodiment. The device 20 and the door 30 that opens and closes the storage compartment inside the body 10.

The second embodiment is here attached to the window 4 by means of a rack 17, in fact the rack 17 is installed on the wall 3 to support the refrigerator of the second embodiment in close proximity to the window. In addition, since the window 4 exposes all of the front surface of the refrigerator when opened differently from the inlet 2 of the door 1 described above, the front surface of the second embodiment rotates forwardly in the same shape as a general refrigerator. The hinge door 30 may be installed. Accordingly, the outflow of cold air from the storage compartment 13 can be reduced as compared with the first embodiment.

Meanwhile, as illustrated in FIG. 3, the door / window-mounted refrigerator of the present invention further includes a rear door 40 formed to face the food input side so that the user can take out the food in the storage compartment 13. desirable. As shown, the rear door 40 includes a part of the cooling device 20 and the inner case 12 in structure, and thus the inner case 12 is substantially divided into two parts. Here, any one of the separated inner cases 12 is attached to the bar and a thermally conductive packing 12a, and the thermally conductive packing 12a seals the internal storage chamber 13 during operation of the refrigerator. The separated inner case 12 is connected to allow the cooling operation to be continued.

In addition, the rear door 30 may further include a high information support member 41 for close contact with the body 10 itself. The high information tank member 41 may be made of the same hook and clip that is caught on the hook and the same shape used in the ice box. This high information tank member 41 gives an improved airtightness to the storage chamber 13.

On the other hand, the cooling structure 20 may further include a fan 24 installed in the storage compartment. The fan 24 circulates the air in the storage chamber 13 to uniform the internal temperature distribution, thereby improving the cooling efficiency.

Such a modification of the present invention is illustrated and described with reference to the first embodiment in FIG. 3, but it can be understood that the present invention can be applied without further modification to the second embodiment, which is a window attached form.

Referring to the operation of the door / window attached refrigerator according to the present invention having such a configuration in more detail as follows.

First, in the case of the first embodiment, as described above, when the food is delivered by opening the feed opening 2, at the same time as shown in Figure 1 the door 30 is upward by the injected food Is pushed over. When the delivery person pulls out the hand after the put food is placed in the storage compartment 13, the door 30 closes the storage compartment 13 by an attached elastic member and the delivered food is relatively low temperature by continuous cooling process. Are preserved in Here, the first embodiment is easy to be damaged because it is installed in the newspaper inlet (2) of the door (1) and is suitable for delivery foods such as milk, yogurt, etc. of a relatively small size. Therefore, the first embodiment can keep the delivered milk and the like freshly even in the absence of the user.

Also in the case of the second embodiment, similar to the always first embodiment, the delivered food can be stored in the storage compartment 13 by the delivery person by opening the window 4 and the door 30 in turn. Since the window 4 has less installation restrictions than the newspaper inlet 2, the second embodiment can be designed to have a storage compartment 13 and an opening 13a that are relatively larger than the first embodiment. That is, the second embodiment can accommodate relatively large foods. Therefore, foods ordered by a user in a store or the like can be delivered by being stored by a delivery person inside the second embodiment directly from outside the house.

On the other hand, a direct current in a proper direction is applied to the thermoelectric element 21 during the operation of the first and second embodiments. At this time, the thermoelectric element 21 simultaneously performs endothermic and exothermic effects by the Peltier effect as mentioned above. The inner case 12 attached to the heat absorbing portion of the thermoelectric element 21 is continuously cooled, thereby keeping the low temperature below a predetermined temperature in the storage chamber 13.

On the other hand, the heat generating portion of the thermoelectric element 21 generates a large amount of heat corresponding to the heat absorbed from the inner case 12. This heat is effectively generated through the heat sink 22, and the heat sink 22 is also effectively cooled by the fan 23.

Although only a few embodiments have been described herein above, it will be apparent to those skilled in the art that the present invention may be embodied in many other specific forms without departing from the spirit and scope thereof. Therefore, the above-described embodiments are to be considered as illustrative and not restrictive, and thus, the invention is not limited to the above detailed description, but may vary within the scope of the appended claims and their equivalents.

Referring to the effect of the door / window attached refrigerator according to the present invention described above are as follows.

In the present invention, the cooling device using the thermoelectric element is to reduce and minimize the refrigerator itself, and the body of the refrigerator is formed to have a structure that can accommodate food through the door and the window. Therefore, due to these characteristics, the present invention can basically provide a refrigerator capable of freshly storing foods that are attached to doors and windows. On the other hand, when attached to a window, the food ordered can be delivered and stored directly in the refrigerator of the present invention by the delivery person by being designed to have an appropriately large size.

The functions of the door / window-mounted refrigerator according to the present invention provide a practical convenience to the user, and are particularly useful when the user is out, bathing or other housework.
