Abstract
Description
- The present invention relates to a refrigerator, and more particularly, to a refrigerator for preventing dewing of door gaskets. The refrigerator is capable of preventing cool air within the refrigerator from causing dew to form directly in the door gaskets.
- Generally, a refrigerator is partitioned into a freezer room or space and a cold room or space, in which food items are stored in frozen and cold states, respectively. So as to selectively open and close the freezer room or space and the cold room or space, a freezer door and a cold room door are separately mounted.
- The interior of the refrigerator is cooled by means of the cool air supplied continuously thereto, and the cool air is continuously produced through the heat exchanging operation of refrigerant, wherein the refrigerant is repeatedly compressed, condensed, expanded and evaporated.
- The cool air supplied to the interior of the refrigerator is evenly sent thereto by convection so that the food items stored within the refrigerator can be maintained at a desired temperature.
- On the other hand, if the cool air supplied to the interior of the refrigerator meets external air of high temperature and humidity, the gaskets, cabinet side surfaces and cover plate of the refrigerator are maintained below a dew point, thereby condensing dew thereon.
- So as to prevent dewing on the gaskets, a hot pipe is coupled to the inside of the cabinet in the conventional practice, thereby allowing the temperature of a portion where dewing is expected to be raised to greater than the dew point temperature.
- In case of the refrigerators developed recently for the purpose of energy saving, however, the prevention of dewing cannot be ensured just with the conventional hot pipe type structure.
- For example, the improvement of the insulation structure of the refrigerator or the improvement of the performance of the cooling cycle of the refrigerator has been recently made to obtain energy saving.
- To improve the performance of the cooling cycle of the refrigerator, the efficiency of a compressor, the heat transfer efficiency of a condenser, and the evaporation efficiency of an evaporator should be improved, and through the improvements, the evaporation temperature at which the refrigerant is evaporated in the evaporator can be lowered.
- Such improvements are advantageous to energy saving, but they do not solve the problem(s) caused by dewing on the refrigerator door gaskets.
- Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a refrigerator for preventing dewing on door gaskets. The refrigerator is capable of preventing cool air within the refrigerator from reaching the door gaskets, and reducing the temperature deviation or difference at a location where internal air and external air meet each other at or near the door gaskets to prevent dewing around the door gaskets.
- To accomplish the above object(s), according to the present invention, there is provided a refrigerator for preventing dewing on door gaskets, including one or more doors, each door having a rear or internal surface; a door gasket along one or more edges of the rear or internal surface of at least one of the one or more doors, configured to prevent cool air in an interior of the refrigerator from leaking to outside the refrigerator; and a cool air shield between a door inside surface and the door gasket, configured to separate the door gasket and the interior of the refrigerator from each other. The door inside surface may extend from the edge of the rear or internal surface of the door(s) toward the interior of the refrigerator.
- According to the present invention, desirably, the cool air shield includes a sealing surface portion contacting the internal surface of the door(s); and a shielding portion extending from one side of the sealing surface portion, configured to shield a space between the door inside surface of the door(s) and the inner surface of the refrigerator and/or to separate the door gasket and the interior of the refrigerator from each other.
- According to the present invention, desirably, one side of the sealing surface portion is in a coupling groove on the rear or internal surface of the door(s) and in contact with the door inside surface.
- According to the present invention, desirably, one side end portion of the sealing surface portion is bent or curved along an inner surface of the coupling groove, and a portion of the door gasket fits with the coupling groove and allows the bent or curved portion of the sealing surface portion to resist and/or press the inner surface of the coupling groove.
- According to the present invention, desirably, the shielding portion has a front end portion bent or curved toward the door gasket.
- According to the present invention, desirably, the front end portion of the shielding portion contacts an inner surface of the refrigerator when the door(s) is/are closed.
- The above and other objects, features and advantages of the present invention will be apparent from the following detailed description of embodiments of the invention in conjunction with the accompanying drawings, in which:
-
FIG. 1 is a cross-sectional view showing a refrigerator for preventing dewing on door gaskets according to the present invention; -
FIG. 2 is an enlarged cross-sectional view showing the part of dotted portion ofFIG. 1 with thefreezer door 3 in the closed position; -
FIG. 3 is a perspective view showing a cool air shield to be disposed in the refrigerator for preventing dewing on the door gaskets according to the present invention; -
FIG. 4 is a cross-sectional view showing temperature regions ofFIG. 2 ; and -
FIG. 5 is a graph showing the temperature of [something; a door gasket?] relative to the dew point according to the present invention and the conventional practice. - Hereinafter, an explanation of a refrigerator for preventing dewing on door gaskets according to the present invention will be given in detail given with reference to the attached drawings.
-
FIG. 1 is a cross-sectional view showing a refrigerator for preventing dewing of door gaskets according to the present invention,FIG. 2 is an enlarged cross-sectional view showing part of the dotted portion ofFIG. 1 with thefreezer door 3 in the closed position, andFIG. 3 is a perspective view showing a cool air shield for preventing dewing on the door gaskets according to the present invention. - Further,
FIG. 4 is a cross-sectional view showing temperature regions ofFIG. 2 , andFIG. 5 is a graph showing the temperatures of the door gaskets relative to the dew point according to the present invention and the conventional practice. - As shown in
FIGS. 1 and2 , afreezer door 3 and a cold room or coldstorage space door 4 are mounted on the cabinet of a refrigerator so as to open and close thefreezer 1 and the cold room orcold storage unit 2 when items like food are put thereinto and/or withdrawn therefrom. - A
door gasket 5 is mounted along one or more edges of the rear or internal surface of each of thefreezer door 3 and thecold room door 4 to prevent the cold air within the refrigerator from leaking through a space between the door and the refrigerator cabinet. For example, onedoor gasket 5 can be mounted on or fixed to the internal surface of thefreezer door 3 along and/or near a lower edge thereof, and another door gasket can be mounted on or fixed to the internal surface of thecold room door 4 along and/or near an upper edge thereof. - The
door gasket 5 includes acoupling portion 5a inserted into and/or fixed to acoupling groove 6 along the edges of the rear or internal surface of each of thefreezer door 3 and thecold room door 4, abuffering portion 5b extending from thecoupling portion 5a and configured to buffer the impact generated when the door is closed, and acontact portion 5c extending from thebuffering portion 5b and contacting the front surface of the refrigerator body or cabinet when thefreezer door 3 is closed. - Further, a
cover plate 8 is on or over apartition 7 that divides thefreezer 1 and thecold room 2 from each other. Amagnet 9 is inserted into thecontact portion 5c of thedoor gasket 5 and holds thefreezer door 3 closed when thecontact portion 5c contacts thecover plate 8 on the front surface of the refrigerator body or cabinet. - The
coupling portion 5a of thedoor gasket 5 is inserted into and/or fixed to thecoupling groove 6 along one or more edges of the rear or internal surface of each of thefreezer door 3 and thecold room door 4, so that thedoor gasket 5 is fixed to the door frame of each of thefreezer door 3 and thecold room door 4 and prevents the cold air within the refrigerator from leaking through the door to the outside. - On the other hand, the
freezer 1 and thecold room 2 have a plurality ofshelves 10 disposed therein on which items are stored and a plurality ofpockets 11 inside thefreezer door 3 and thecold room door 4 to accommodate food containers or drinks therein. Pocket bars (not shown) are inside thepockets 11 so as to prevent the food containers or drinks in thepockets 11 from escaping or falling. - According to the present invention, as shown in
FIG. 2 , a thincool air shield 100 is disposed between thedoor gasket 5 and a door insidesurface 3a to separate the interior of thefreezer 1 from thedoor gasket 5. That is, thecool air shield 100 is adapted to shield the space between the door insidesurface 3a and an inner surface 1a of thefreezer 1 at a relatively distant point from thedoor gasket 5 toward the interior of thefreezer 1. The door insidesurface 3a as shown inFIG. 2 extends from one or more edges of the rear or interior surface of thefreezer door 3, toward the interior of the refrigerator (or freezer). However, when thefreezer door 3 does not have a lower portion that extends into thefreezer 1, the door insidesurface 3a may be an internal surface of thefreezer door 3 just above thedoor gasket 5 and/or thecool air shield 100. - As shown in
FIG. 3 , thecool air shield 100 has asealing surface portion 101 that contacts the door insidesurface 3a of thefreezer door 3 and ashielding portion 102 that is bent and that extends from one side of thesealing surface portion 101 to shield the space between the door insidesurface 3a of thefreezer door 3 and the inner surface 1a of thefreezer 1. Alternatively, theshielding portion 102 is configured to shield the space between thedoor gasket 5 and an interior of thefreezer 1. - In more detail, one side or edge of the
sealing surface portion 101 of thecool air shield 100 is inserted into thecoupling groove 6 and/or brought into close contact with thecoupling groove 6, together with thedoor gasket 5. At the same time, an opposite side or edge of thesealing surface portion 101 extends toward the interior of thefreezer 1 along the door insidesurface 3a of thefreezer door 3, spaced apart from thedoor gasket 5. - The end portion of the
sealing surface portion 101 toward the interior of thefreezer 1 elastically contacts the door insidesurface 3a of thefreezer door 3, so that even if a long period of time has passed, thesealing surface portion 101 does not separate from the door insidesurface 3a of thefreezer door 3 due to its own weight or temperature changes. - When the
freezer door 3 is closed, thedoor gasket 5 may push thesealing surface portion 101 toward the door insidesurface 3a, thereby allowing thesealing surface portion 101 to be in contact with the door insidesurface 3a. - Furthermore, when the
sealing surface portion 101 elastically pushes toward the door insidesurface 3a of thefreezer door 3, as theshielding portion 102 shields the door gasket 5 from the inner surface 1a and/or interior of thefreezer 1, separation of thesealing surface portion 101 from the door insidesurface 3a can be prevented. - Further, the
shielding portion 102 may comprise or be made of a flexible material that may have a curtain shape and/or extend from thesealing surface portion 101 toward the inner surface 1a of thefreezer 1 and shield the space communicating with the door gasket 5 (e.g., the space under the door insidesurface 3a, between theshielding portion 102 and the door gasket 5). - Further, the
shielding portion 102 has a front end portion bent toward thedoor gasket 5 to inhibit or prevent locking when thefreezer room door 3 is closed. - Accordingly, the formation of the
cool air shield 100 prevents the cool air supplied to thefreezer 1 from directly coming into contact with thedoor gasket 5, thereby avoiding the freezing of the door gasket 5 (or cooling of the door gasket 5 to below the dew point), and thus reduce the deviation or difference of the temperature at a location where freezer internal air and external air meet each other at or near a boundary of thedoor gasket 5 to prevent dewing on or around thedoor gasket 5. - That is, as shown in
FIG. 4 , thedoor gasket 5 is not directly between a low temperature dry region A within thefreezer 1 and a high temperature and high humidity region C outside the refrigerator. Rather, a temperature drop suppressing region B is formed between thedoor gasket 5 and the low temperature dry region A within thefreezer 1 by thecool air shield 100, thereby reducing drastic temperature deviations and/or differences and thus preventing the formation of dew on or near thedoor gasket 5. - The
shielding portion 102 may contact the inner surface 1a of thefreezer 1, but even when spaced apart therefrom by a small distance or gap, the temperature drop suppressing region B can be effective. - According to the present invention, as shown in
FIG. 5 , the temperature of thedoor gasket 5 or thecover plate 8 is increased much more than when compared with the conventional practice, so that the time that the door gasket 5 or thecover plate 8 is below the dew point becomes shorter than in the conventional practice, and the lowest temperature of thedoor gasket 5 or thecover plate 8 becomes higher than in the conventional practice, thereby preventing (or at least significantly reducing) dewing around thedoor gasket 5 on thefreezer door 3. - Of course, the
cool air shield 100 may be disposed on thecold room door 4 to shield the space between the door inner surface 4a of thecold room door 4 and the inner surface or interior of thecold room 2. - As mentioned above, accordingly, the refrigerator for preventing dewing on the door gaskets according to the present invention is provided with a cool air shield that may be disposed between an inside surface of the freezer door and the door gasket to shield the space between the inside surface of the freezer door and the inner surface or interior of the freezer, thereby preventing the cool air supplied to the freezer from directly contacting the door gasket and further avoiding the freezing of the door gasket.
- Additionally, the present invention reduces a temperature deviation or difference at a location where internal air and external air meet each other (e.g., at or near a boundary of the door gaskets), thereby preventing dewing on or around the door gaskets.
- While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
