Abstract
Description
- The present invention relates to a refrigerator including a condenser.
- A refrigerator conventionally comprises a refrigerator body with a cooling compartment and a freezing compartment. Doors are mounted to the front of the refrigerator body to separately open and close the compartments and a component chamber is provided in a lower space of the refrigerating body wherein a compressor to compress a refrigerant and a condenser to condense the refrigerant supplied from the compressor are installed.
- Additionally, a cooling means to cool hot air generated in the compressor and the condenser is mounted in the component chamber. The cooling means include an inlet and an outlet located on a rear cover and positioned adjacent to the condenser and compressor respectively. A fan is disposed in the compartment chamber such that an airflow is generated therethrough.
- However, the fan and condenser are generally arranged relative to each other such that a fan 102 is disposed to blow air towards a condenser 103 located in a
cooling chamber 110, as illustrated in Figure 5A, or otherwise, such that afan 112 is disposed to draw air from acondenser 113 located in acooling chamber 110 as illustrated in Figure 5B. - A problem with the arrangement illustrated in Figure 5A wherein the fan 102 blows air towards the condenser is that direct movement of the air is distorted in front of the condenser 103 because of the resistance generated by a tube and fins of the condenser 103. Similarly, a problem with the arrangement illustrated in Figure 5B wherein the
fan 112 draws air from thecondenser 113 is that direct movement of the air is distorted because of the resistance generated by the rear of thecondenser 113. - The present invention seeks to provide a refrigerator which overcomes or substantially alleviates the problems discussed above and in which the heat radiating efficiency is improved.
- A refrigerator according to the present invention is characterised in that the condenser comprises a plurality of condensing elements disposed separately from each other.
- The refrigerator may further comprise at least one fan wherein the fan is disposed between the plurality of condensing elements.
- Preferably, the condenser comprises a first and a second condensing element and a fan is disposed between the first and second condensing elements such that air is drawn through the first condensing element and is subsequently blown through the second condensing element.
- In a preferred embodiment, the plurality of condensing elements are integrally connected.
- Advantageously, the refrigerator further comprises a compressor wherein air drawn through the plurality of condensing elements is supplied to the compressor.
- Embodiments of the invention will now be described, by way of example only, with reference to Figures 1 to 4 of the accompanying drawings, in which:
- Figure 1 is a perspective view of a refrigerator in accordance with the present invention;
- Figure 2 is a schematic diagram illustrating a component chamber of the refrigerator;
- Figure 3 is a diagram illustrating the airflow in the compartment chamber shown in Figure 2 when a fan located therein is operated;
- Figure 4 is a graph showing the heat radiating efficiency of a conventional refrigerator compared to a refrigerator according to the present invention; and
- Figures 5A and 5B illustrate the airflow in the component chamber of a conventional refrigerator when a fan located therein is operated.
- Referring to the drawings, there is shown in Figure 1 a refrigerator comprising a
refrigerator body 1 with acooling compartment 10 and afreezing compartment 20 located internally therein on the right and left sides respectively. Therefrigerator body 1 also includes acooling compartment door 11 and afreezing compartment door 21 to open and close their respective front openings.Door guides compartment doors - A plurality of
racks boxes compartments - Referring to Figure 2, a
component chamber 30 is located in a rear lower space of therefrigerator body 1. Within thecomponent chamber 30 are installed a number of components including acompressor 31 to compress a refrigerant, acondenser 32 to condense the refrigerant from thecompressor 31, and afan 33 provide an air flow across thecondenser 32. Thecompressor 31 and thecondenser 32 are separately installed at opposite sides of thecomponent chamber 30. - The
condenser 32 and thefan 33 are mounted to a supportingplate 34 which is installed in thecomponent chamber 30. Thecondenser 32 comprises afirst condensing element 32a and asecond condensing element 32b to condense the refrigerant supplied from thecompressor 31. The first andsecond condensing elements fan 33 is disposed in the space therebetween. - The
first condensing element 32a is located between thecompressor 31 and thefan 33 and thefan 33 is located in a space between thefirst condensing element 32a and thesecond condensing element 32b. - The flow of air inside the
component chamber 30 due to thefan 33 is shown in Figure 3. Air is drawn through the secondcondensing element 32b by thefan 33 and is subsequently blown through thefirst condensing element 32a by the fan wherein the air having passed through thefirst condensing element 32a is directed toward thecompressor 31. - When a component installed in the
component chamber 30, such as thecompressor 31, is operated when the refrigerator starting operating, the air temperature inside thecomponent chamber 30 is raised due to the heat generated as a result of operation of the component. The air inside thecomponent chamber 30 is then circulated dependent on the operation of thefan 33. - According to the present invention, the
fan 33 draws air through the second condensingelement 32b and subsequently blows it through the first condensingelement 32a. Thecondenser 32 includes the first and thesecond condensing parts fan 33 is displaced between the first condensingpart 32a and the second condensingpart 32b. As a result, the refrigerator according to the present invention has an improved condensation efficiency compared with the conventional refrigerators as illustrated in Figures 5A or 5B. - The above-described features of the present invention may be more clearly ascertained by reference to a graph shown in Figure 4, which compares the condensing efficiency of the conventional art and that of the present invention.
- According to the graph shown in Figure 4, a bar elevated higher toward a vertical axis indicates a higher heat radiation efficiency. Referring to the graph, the condensation efficiency of the refrigerator according to the present invention, is remarkably higher than the conventional refrigerator as illustrated in Figures 5A and 5B.
- In the exemplary embodiment described above, a pair of condensing parts are provided. However, the number of condensing parts is not limited but may be increased as necessary. Likewise, a fan is interposed between the pair of condensing parts in the above-described embodiment, but the number of fans may be increased according to the number of condensers.
- Also in the above-described embodiment, a plurality of condensing parts are integrally connected. However, the plurality of condensing parts are manufactured independently and are then connected by a coupler.
- Although an embodiment of the invention has been shown and described, it will be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles of the invention, the scope of which is defined in the claims and their equivalents and the foregoing description should be regarded as a description of a preferred embodiment only.
