Abstract: Provided is a thermoelectric cooling device comprising: a thermoelectric module; a heat sink having a body, which has on one side a contact surface coming into contact with a heating side of the thermoelectric module, and a plurality of heat dissipation fins, and emitting the heat transferred from the heating side of the thermoelectric module; a heat pipe coupled to a mounting groove which is formed on the contact surface of the heat sink, and for transferring heat by means of a working fluid stored therein; and a cooling fan for forming the airflow to the heat sink, wherein the heat pipe comprises a plurality of corner-extension heat pipes extending to a corner area of the heat sink from the central part of the heat sink on which the thermoelectric module is installed, and the shape of the mounting groove corresponds to the shape of the corner-extension heat pipes.

Abstract: An ice-making water purifier includes a water tank unit, an instantaneous heating device, an extraction member, an ice-maker, a supply pump, an ice-making water inlet passage, an ice-making water supply valve, a flow rate sensor, and a controller configured to control driving of the supply pump and the opening and closing of the ice-making water supply valve such that purified water corresponding to a predetermined supply amount of ice-making water is supplied to the ice-maker on the basis of a flow rate value measured by the flow rate sensor. The controller controls the opening and closing of the channel such that purified water is preferentially supplied to the instantaneous heating device among the instantaneous heating device and the ice-maker.

Abstract: Provided is a water purifier comprising: a filter unit which has a reverse osmosis membrane filter; a supply valve; an instantaneous heating device which is provided with an inflow port, and an outflow port, and which heats and purified water entering through the inflow port and flowing to the outflow port, so that hot water is discharged through the outflow port; an extraction member; a supply pump; a domestic water drain line; a hot water drain line; a hot water drain valve; and a control unit which controls the opening/closing of respective flow channels of the hot water drain line and the domestic water drain line so that, among a hot water draining process through the hot water drain line, and a domestic water draining process through the domestic water drain line, the hot water draining process is carried out first.

Abstract: Disclosed herein are a card reader, a terminal and a method for processing payment information using the same, wherein the card reader may include a connector which is connected communicable with an external terminal; a reader unit which is configured to obtain an IC card (Integrated Circuit Card) information; a layer configuration unit wherein a key input layer wherein a plurality of keys are disposed for password inputs, is randomly formed; an interface unit which is able to transmit the information on the randomly formed key input layer to the external terminal via the connector and receive from the external terminal the position information corresponding to the inputted IC card password at the key input layer; and a password detection unit which is employed to process the received position information and detect the password inputted from the external terminal.

Abstract: A front panel operating apparatus and method of a vehicle display device such as a car audio can include a main chassis for accommodating an audio device, a front panel provided in the front side of the main chassis that opens or closes to allow access to a record medium for the audio device. The front panel can have a display part in the front side thereof. A supporting panel can be hinge-coupled to a lower side of the front panel to move a lower end of the front panel forward and backward by sliding from a prescribed location of the main chassis in forward and backward directions of the main chassis. A vertical guide can be formed at the front side of the main chassis, and a protrusion formed on the front panel can be inserted into the vertical guide for controllably moving an upper portion of the front panel up and down.

Abstract: A front panel driving apparatus for a car audio system comprises a main chassis, a slider base fitted inside the main chassis, and a slider. A plurality of roller structures are provided for promoting a more stable motion of the slider. The roller structures are formed between the slider base and the slider. A front panel is opened or closed by translating vertically when the slider moves back and forth. A lower end portion of the front panel is hinged upon a front end portion the slider. Projections that are protruded from both upper ends of the front panel are mounted inside generally vertical tracks of a front frame that is attached to a front of the main chassis.
