Embodiment Construction

[0051] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0052] figure 1 is a perspective view of a refrigerator according to an embodiment of the present invention, figure 2 It is an exploded perspective view of a refrigerator according to an embodiment of the present invention, image 3 is along figure 1 The XX' line sectional view shown, Figure 4 will be image 3 A cross-sectional view of an enlarged representation of the thermoelectric module is shown.

[0053] The refrigerator may include: a body 1 forming a storage room S; a door 2 for opening and closing the storage room S; and a thermoelectric module 3 for cooling the storage room S.

[0054] The body 1 may be formed in a box shape. The height of the main body 1 can be more than 400mm and less than 700mm, so that it can be used as a bedside table.

[0055] The refrigerator in this embodiment may be a bedside refrigerator with a relatively l...

Abstract

A refrigerator provided by the embodiment of the invention includes: a main body having a storage chamber; a door for opening and closing the storage chamber; a thermoelectric module having a coolingsink for cooling the storage chamber and a heat sink for radiating heat sucked by the cooling sink; a cooling fan for circulating air to the cooling sink and the storage chamber; a heat-radiation fanfor flowing outside air to the heat sink; and a control unit for controlling the thermoelectric module, the cooling fan, and the heat-radiation fan, in which when the outside temperature exceeds the set temperature, the control unit can rotate each of the cooling fan and the heat-radiation fan at a high-speed, in which, when the outside temperature is equal to or lower than the set temperature andthe storage chamber temperature is in the upper limit range, the control unit can rotate each of the cooling fan and the heat-radiation fan at a medium-speed lower than a high-speed, and in which, when the outside temperature is equal to or lower than the set temperature and the storage chamber temperature is lower than the upper limit range, the control unit can rotate each of the cooling fan and the heat-radiation fan at a low-speed lower than a medium-speed, and thus there are advantages that the temperature deviation in the storage chamber, which can be generated when the outside temperature is high, can be minimized and noise can be minimized when the outside temperature is not high.

Description

technical field [0001] The present invention relates to a refrigerator, and more specifically, to a refrigerator using a thermoelectric module to cool a storage room. Background technique [0002] Refrigerators are devices that refrigerate or store food, medicines, and cosmetics at low temperatures to prevent them from rotting or deteriorating. [0003] The refrigerator includes: a storage room for storing food or medicines or cosmetics; and a cooling device for cooling the storage room. [0004] An example of the cooling device may be constituted by a refrigeration cycle device including a compressor, a condenser, an expansion mechanism, and an evaporator. [0005] Another example of the cooling device may be constituted by a thermoelectric module (TEM: Thermoelectric Module). The thermoelectric module utilizes a phenomenon that, when different metals are combined and current is passed, a temperature difference is generated on both end surfaces of the different metals. ...
