Detailed Description
The present invention will be described in more detail with reference to the accompanying drawings and examples.
Hereinafter, preferred embodiments of a refrigerator according to the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or corresponding portions are denoted by the same reference numerals, and redundant description is omitted.
Fig. 1 is a front view showing an internal structure of a refrigerator 100 according to the present invention. Fig. 2 is a sectional view showing the position of the drain pipe 30 of the refrigerator 100 according to the present invention. Fig. 3 is a plan view showing a water collecting tray of the refrigerator 100 of the present invention. Fig. 4 is a perspective view showing the drain pipe 30 and the water accumulation tray of the refrigerator 100 according to the present invention.
As shown in fig. 1 to 4, a refrigerator 100 includes: an evaporator 10; a water collecting tray 20 provided below the evaporator 10 and having a drain port 21; a drain pipe 30 connected to the drain port 21 and discharging water in the water accumulation tray 20 to the outside of the refrigerator 100; a heater 50 disposed between the evaporator 10 and the water accumulation tray 20 for heating and defrosting the evaporator 10; the heat conductor 40 includes a radiation portion 41 and an extension portion 42, the radiation portion 41 is provided on the water collecting tray 20 and radiates heat of the heater 50, and the extension portion 42 is provided to extend to the inside of the drain pipe 30.
More specifically, the heater 50 is disposed below the evaporator 10 with a space from the evaporator 10. In order to prevent the frost water of the evaporator 10 from dropping to the heater 50, a shielding part 51 may be further provided above the heater 50. The shielding part 51 can not only shield the defrosting water, but also uniformly radiate the heat of the heater 50 to the evaporator 10, thereby achieving a better defrosting effect. Further, the heater 50 is also provided at a distance from the heat conductive member 40. Therefore, when the skin of the heater 50 is damaged in an extreme case, the heat-conducting member 40 does not contact the heater 50, so that a safety hazard such as electrification of the refrigerator 100 does not occur.
In the refrigerator 100 of the present invention, the heat generated by the heater 50 during operation is transferred to the drain pipe 30 through the heat conducting member 40, thereby increasing the temperature in the drain pipe 30. Even if the water staying in the drain pipe 30 is frozen, the ice is melted by the heat conductive member 40, and the water flows out of the refrigerator 100 smoothly. Therefore, according to the present invention, the refrigerator 100 extends into the drain pipe 30 through the heat conduction member 40, so that the overall temperature in the drain pipe is raised, and the water in the drain pipe 30 can be effectively prevented from freezing. Through experiments, the highest temperature at points a, b and c in fig. 2 can be increased by more than 15 ℃ after the heat-conducting member 40 is used in the defrosting process, so that the freezing and freezing of the water in the drainage pipe can be avoided even if the retained water exists. In addition, in the case where the heat conductive member 40 is provided, the foaming layer 70 may be made to be a base heat insulation, so that the thickness of the foaming layer 70 at the drain pipe 30 may be reduced, thereby increasing the internal volume of the refrigerator 100.
Fig. 5 is a perspective view showing the water accumulation tray 20 of the refrigerator 100 according to the present invention. Fig. 6 is a perspective view showing the extension 42 of the heat conductor 40 of the refrigerator 100 according to the present invention.
As shown in fig. 5 and 6, in the refrigerator 100 of the present invention, the heat conducting member 40 is configured to match the shape of the water collecting tray 20 and the drain pipe 30. Preferably, the radiating portion 41 (hatched portion) is composed of a metal foil (e.g., aluminum foil) and is attached to the water collecting tray 20. Here, the radiation part 41 may cover the entire inner surface of the water accumulation tray 20. However, the water accumulation tray 20 may be covered with a part of the inner surface thereof as long as the heat can be sufficiently radiated. According to such a configuration, since the area of the drip tray 20 is large, by attaching the metal foil (the radiation portion 41) to the drip tray 20 in a large area, the radiation heat of the heater 50 can be sufficiently received and conducted into the drain pipe 30, thereby preventing the water in the drain pipe 30 from freezing, and the heat of the heater 50 can be reflected to the evaporator 10, thereby further improving defrosting efficiency.
In addition, the extension portion 42 may be a heat conducting sheet or a heat conducting pipe, and the extension portion 42 may also have flexibility. With this structure, the extension 42 can be easily inserted into the narrow drain pipe 30.
In addition, one end of the extension portion 42 extending to the inside of the drain pipe 30 is preferably provided in a curved shape, and may be formed in a circular ring shape as shown in fig. 6, for example. According to such a structure, the tip of the extension 42 can be prevented from damaging the drain pipe 30 at the time of installation.
In addition, it is preferable that the extension part 42 includes a connection part 421 and an insertion part 422, the connection part 421 is fixed to the radiation part 41, and the insertion part 422 is inserted into the drain pipe 30. Here, the connection portion 421 is attached to the radiation portion 41 by, for example, a metal foil tape 60 (aluminum foil tape). According to such a structure, heat can be efficiently transmitted to the drain pipe 30, thereby preventing the water in the drain pipe 30 from freezing.
Further, it is preferable that a claw 423 engageable with the water collecting tray 20 is provided at one end of the connection portion 421, and a locking groove is provided at a corresponding position of the water collecting tray 20. Through the gomphosis of jack catch and draw-in groove, can firmly be fixed connecting portion 421 with ponding dish 20, prevent that heat-conducting member 40 from droing. However, the fixing structure of the connection portion 421 of the heat conductor 40 and the water accumulation plate 20 is not limited to the engagement and fixation, and other known fixing structures may be employed.
According to the utility model discloses a refrigerator 100 can prevent that the water in drain pipe 30 from freezing and reducing the thickness of drain pipe 30 department foaming layer 70 to because heat-conducting member 40 and heater 50 contactless, can get rid of the potential safety hazard because of heater 50's epidermis destroys and bring.
While the present invention has been described in detail in connection with the drawings and the examples, it is to be understood that the above description is not intended to limit the present invention in any way. The present invention may be modified and varied as necessary by those skilled in the art without departing from the true spirit and scope of the invention, and all such modifications and variations are intended to be included within the scope of the invention.
