Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an electronic cooling pillow, and more particularly, to an electronic cooling pillow whose cooling power can be adjusted.

[Background of the invention J A conventional Naruko cooling pillow will be explained with reference to FIGS. 1 to 5.

The electronic cooling pillow consists of a pile body 1 and a power supply device 2.
Connect the 12 output lugs 6 to the sockets 4 of the pile body 1,
When a person turns on the power on/off switch 5 installed on the rear side of the pile body 1, a DC' current flows from the power supply 2 to the electronic cooling element B built in the pile body 1, and comes into close contact with the heat absorption side of the thermoelectric cooling element B. The heat transfer block and cooler 8 provided are cooled, and the heat radiator 9 provided in close contact with the heat radiation side of the electronic cooling element 6 is heated. The nine radiators are installed behind the pile body 1 and covered with a guard 10, and the heat from the radiators 9 is radiated into the outside air by natural convection.

The Naruko cooling pillow configured as described above has a power on/off switch 5.
Opens and closes cooling operation. In such an electronic cooling pillow, if the user feels that the pillow is too cold, he or she must turn off the power supply switch or place a towel or the like on the pile body to adjust the temperature. but,
There was a drawback that the pillar body quickly warmed up when the power supply switch was turned off, and another drawback was that when a towel or the like was placed on the pillar body, it did not feel cold at first when the head was placed on the pillow.

[Object of the Invention J The object of the present invention is to eliminate the above-mentioned drawbacks, prevent excessive cooling, and provide a highly safe electronic cooling pillow.

[Summary of the invention]

That is, in a Naruko cooling pillow consisting of a pillar body equipped with an electronic cooling element, a radiator, a cooler, and a 11t11i on/off switch, and a power supply device, a control device for controlling the power supplied to the electronic cooling element is provided, and the control device is provided. By connecting the device to the electronic cooling element and the drowsy VC1f row and fixing the heat generating part τ of the control device to the radiator, the control device can be manually or automatically controlled to control the electronic cooling device. In addition to increasing or decreasing the power supplied, it prevents the heat-generating part from heating up to high temperatures, prevents it from becoming too cold, and improves overall performance.

[Embodiment J of the Invention An embodiment of the present invention will be described below with reference to FIGS. 4 and 5.

FIG. 4 is a circuit diagram of the pillar body 1, in which one terminal of the socket 4, which is the connection part with the power supply device 2, is connected to one end of the thermoelectric cooling element 6, and the other terminal of the socket 4 is connected to the t source. Connected to one of the terminals of the on-off switch 5, and connected to one of the terminals of the on-off switch 5
A control device 11 is electrically connected in series between the other terminal of the electronic cooling element B and one end of the electronic cooling element B. The control device 1
1 is constituted by a parallel circuit of a resistor 12 and a switching device 16, and the resistor 12 is fixed to the heat sink 9 with screws 14a and 14b. The heat radiator 91-1. , opening/closing device 11
Total power Wa supplied from power supply device 2 when 6 is human
The power supply device 2 is designed to be able to sufficiently radiate both the heat Q1 generated by the thermoelectric cooling element 6 and the heat Q2 carried from the cooler 8 side to the radiator 9 side by the electronic cooling element 6. When only the electronic cooling element 6 is loaded, the maximum force W1
It is designed so that it can be extracted, that is, Wo = W+.

In this embodiment, when the opening/closing device 16 is set to a person and the Nariko cooling pillow is used, the resistor 12 is opened.

Since it is electrically short-circuited by the closing device 16, the operation of the electronic cooling pillow according to this embodiment is the same as that of the conventional electronic cooling pillow. Next, when the switching device 16 is turned off and the Naruko cooling pillow is used, the resistor 12 acts as a voltage drop device,
A part of the power W2 supplied to the column main body 1 from the power supply device f2 is consumed by the resistor 12, and the electric power W3 supplied to the electronic cooling element B decreases. Since the ability to transfer heat from the side to the side of the radiator 9, that is, the cooling power, is approximately proportional to the resultant force Ws supplied to the electronic cooling element B, the cooling power of the electronic cooling element B decreases. At this time, the power W4 consumed by the resistor 12 becomes heat Qs, which is radiated by the heat radiator 9. Such heat Qs acts as a thermal load on the radiator 9, increases the temperature of the radiator 9, increases the temperature difference between the heat radiation side and the heat absorption side of the electronic cooling element B, and increases the cooling efficiency of the electronic cooling element 6. lower. Due to the dual effects described above, operation can be performed with a weakened cooling power, and even if the resultant force W5 consumed by the resistor 12 is small, the rate of reduction in the cooling power can be increased. Also, the force W4 consumed by the resistor 12 is the force W4 supplied from the t-source device #2.
2(7) Partial Teh F), W2 = Ws +VV4
Since the resistor 12 is electrically connected in series with the electronic cooling element 6, the matching condition of power supply unit #2 is violated.
W2 (The relationship W+ holds true. Therefore, C resistor 12
Regarding the squid W41/C consumed in , W4<W+ holds true, and the resistor 12 does not generate abnormal heat. Heat radiation a9 is the heat QI equivalent to the maximum power VV + supplied from the power supply 2
and the radiator 9 from the cooler 8 side to the electronic cooling element 6.
Since the V-shaped design is designed to sufficiently radiate both the heat Q2 carried to the side, the heat Qs generated by the resistor 12 can be sufficiently radiated by the heat radiator 9, and the heat radiator 9 is fixed to the heat radiator 9. The resistor 12 does not become abnormally high temperature and is perfect. By changing the resistance value of the fvC resistor 12, any weak cooling operation can be easily set.

According to the present invention, if the user of the Seiko cooling pillow feels too cold, the pillar body can be equipped with a control device for controlling the 9-ku power (ii) to easily control the cooling power. Since it does not stop cooling, the cooling part of the pile body does not warm up too quickly, and there is no need to put a towel on it to adjust it, making it extremely easy to handle. Since the generated power does not increase, the control device and radiator will not become abnormally high temperature, making it safe.Furthermore, even if the electronic cooling element fails and short-circuits, and the full power of the control device IC is applied, the heat generated will not increase. The amount of heat is less than the amount of heat radiated by the radiator during normal operation of the electronic cooling pillow, so the control device and radiator will not reach abnormally high temperatures, making it extremely safe.
By using a parallel circuit of a voltage drop device and a switchgear as a control device, a switchgear that does not generate heat can be installed in a position where it is easy to operate, and by using a resistor as a voltage drop device, the structure is simple. can be made into an inexpensive device. Furthermore, since the failure mode of resistors is generally disconnection, safety is also increased.

It is important that electronic cooling pillows are easy to operate and safe, and since they are used while sleeping, it is extremely important that they are safe. According to the present invention, an electronic cooling pillow with a simple structure and extremely high safety can be provided.
