Abstract

PURPOSE:To regulate the surface temperature of thermoelectric elements so as to provide the most suitable radiant circumstances for the bodily sensation of a person who works at a desk, by furnishing screens, in which two or more thermoelectric elements are extensively arranged, to the rear, right and left sides of a desk top, and providing a voltage switch-over regulator for adjusting input voltage. CONSTITUTION:Two or more thermoelectric elements 3 are extensively arranged inside screens 2. The thermoelectric elements 3 are thermo-conductively connected to conduction plates 4 in order to uniform radiant energy per unit area at every height, and further to radiating fins 5 in order to make the waste heat, which is generated from the back of the thermoelectric elements 3, radiate effectively. The room air is sucked from a suction port 6 closed at a lower portion of the screens 2 by a fan 7 to discharge the waste heat generated from the radiating fins 5 into a room through a discharge port 8. The thermoelectric elements 3 are grouped according to their heights, and their surface temperatures are regulated by adjusting knobs 10 on a voltage regulator 9.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a desk with a radiant heating and cooling system that creates a comfortable desk work space.

BACKGROUND OF THE INVENTION In recent years, desks with heating and cooling devices built into them have come into use. Hereinafter, a conventional desk with an air-conditioning device will be explained based on FIG. 4. That is, it has a configuration in which cold air is blown out from a cold air outlet 103 provided above a screen 102 attached to the back surface of the desk top 1, and hot air is blown out from a warm air outlet 104 provided below. be.

Problems to be Solved by the Invention However, with the above-mentioned conventional devices, when the cold air is blown, the upper body, especially the face, etc., are well exposed to the cold air and a cooling sensation can be obtained, but the effect on the torso and lower body is poor, and the cold air is not exposed to the face. The problem was that it gave a strong sense of bother.

Also, when hot air is blown out, the feet feel good, but the upper body is far away from the hot air outlet.
This poses a problem in that the user is exposed to cooled, low-temperature warm air, which makes the user feel colder and more uncomfortable.

The present invention focuses on this problem, and provides a radiant environment that is optimal for cooling and heating desk work spaces for the entire body of each individual.
Traditionally it was cloth. The purpose is to provide a comfortable desk work space that eliminates the bothersome feeling of wind, which is a drawback of cold and hot air systems.

Means for Solving the Problems In order to achieve the above object, the present invention provides a screen in which a plurality of thermoelectric elements are arranged on the entire back surface and left and right sides of the top plate, and the input voltage of the thermoelectric elements can be adjusted and switched. The screen is provided with a voltage adjustment section for controlling the voltage.

Function: This configuration changes the surface temperature of the thermoelectric elements built into the screen and grouped at each height position, creating a radiation environment optimal for the experience of individuals working at a desk.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 to 3. As shown in the figure, a screen 2 is attached to the back and both left and right sides of a desk having a top plate 1, and a plurality of thermoelectric elements 3 are arranged on the entire surface inside the screen 2, and a plurality of thermoelectric elements 3 are arranged on the entire surface inside the screen 2. In order to make the radiant energy per unit area uniform, the conductive plate 4 and the thermoelectric element 3 are thermally coupled, and in order to more efficiently radiate the waste heat generated on the opposite side of the thermoelectric element 3, a radiation fin is provided. 6 is in a thermally bonded state. In order to treat the waste heat generated from the thermoelectric element 3, a screen 2 is provided.
Indoor air is sucked in through the suction port 6 provided at the lower part of the fan 7 by the rotation of the fan 7, and waste heat radiated from the radiation fins 6 is discharged into the room through the air outlet 8. Also, they were divided into groups according to their height positions (A1 e A2 m...A
n) A voltage regulator 9 for changing the surface temperature of the thermoelectric element 3 is provided on the side surface of the screen 2, and a variable resistor 11 for adjusting the input voltage to the individual thermoelectric elements 3 is divided into groups. The voltage regulator 9 has a configuration corresponding to the thermoelectric element 3.
Built-in. 1o is an adjustment knob for the variable resistor 11, and 12 is a power supply unit.

In this configuration, when the power supply unit 12 is energized and the adjustment knob 1o is adjusted to set the cold radiation field and the warm radiation field according to the individual's preference, arbitrary radiation is emitted from the thermoelectric elements 3 divided into groups A1 to An. Energy is radiated towards the human body.

As is clear from the explanation of the embodiments above, according to the present invention, in the space around the pile, any radiant energy field that suits the individual's preference can be obtained from the desk with the radiant air conditioning system, and the energy can be distributed throughout the whole body. It is possible to realize a desk with a radiant heating and cooling system that does not cause the trouble associated with forced convection systems and can provide a comfortable environment that suits the individual's experience.
