Abstract

A foothold including a thermoelectric module includes a body having an air channel in which a suction fan is provided and a dissipation channel in which a dissipation fan is provided, and a cover including an air discharge portion disposed on the body. Further, the thermoelectric element is disposed between the dissipation heat sink and the cover.

First claim

What is claimed is:

1. A foothold comprising:
a body having an air channel in which a suction fan is provided and a dissipation channel in which a dissipation fan is provided;
a dissipation heat sink provided in the body, the dissipation heat sink being positioned in the dissipation channel;
a cover disposed to cover the body and having a top surface on which a user's feet are placed; and
a thermoelectric element disposed between the dissipation heat sink and the cover,
wherein the cover includes:
a cover plate to contact with the thermoelectric element, the cover plate including an air discharge portion to discharge air that has passed through the air channel; and
at least one fin extending from the cover plate, the at least one fin being positioned in the air channel.

2. The foothold of claim 1 , wherein the air channel includes a first channel and a second channel, and
the dissipation channel is disposed between the first and second channels.

3. The foothold of claim 2 , wherein the suction fan includes:
a first fan disposed at a lower portion of the body to force the air to flow through the first channel; and
a second fan disposed at a lower portion of the body to force the air to flow through the second channel.

4. The foothold of claim 2 , wherein the body includes a first part forming the first channel and a second part forming the second channel, and
the first and second channels are disposed at center portions of the first and second parts, respectively.

5. The foothold of claim 4 , wherein the cover is disposed over the first and second parts, and
an intermediate channel is formed between a bottom surface of the cover and top surfaces of the first and second parts.

6. The foothold of claim 5 , wherein the at least one fin extends downward from the cover and is positioned in the intermediate channel.

7. The foothold of claim 6 , wherein the at least one fin extends in a front-rear direction from a bottom surface of the cover and guides the air, which has passed through the first and second channels, to front portions and rear portions of the first and second parts.

8. The foothold of claim 1 , wherein the air discharge portion is disposed over the intermediate channel.

9. The foothold of claim 1 , wherein the cover is detachably coupled to the body.

10. The foothold of claim 1 , wherein the cover plate includes a plate protrusion protruding downward from a bottom surface of the cover plate and being in contact with a heat absorption/dissipation portion of the thermoelectric element.

11. The foothold of claim 10 , further comprising a module insulator surrounding the thermoelectric element and having an insulator hole,
wherein the plate protrusion is inserted into the insulator hole.

12. The foothold of claim 1 , wherein the air discharge portion is formed in a plurality of rows and a plurality of columns, and
the at least one fin comprises a plurality of fins formed in a plurality of columns.

13. The foothold of claim 12 , wherein a column of the plurality of fins is aligned in a column of the air discharge portion.

14. The foothold of claim 4 , wherein the body further includes a third part disposed between the first and second parts, the third part forming the dissipation channel.

15. The foothold of claim 14 , wherein the dissipation channel includes:
a sink suction side channel formed from the dissipation fan to the dissipation heat sink; and
a sink discharge side channel extending from the dissipation heat sink to a side surface of the body.

16. The foothold of claim 15 , wherein the dissipation fan is disposed at a lower portion of the body.

17. The foothold of claim 15 , further comprising a dissipation cover provided on the side surface of the body, the dissipation cover to discharge the air which has flowed through the dissipation channel.

18. A foothold comprising:
a body having an air channel and a dissipation channel;
a suction fan provided in the air channel;
a dissipation fan provided in the dissipation channel;
a dissipation heat sink provided in the body, the dissipation heat sink being positioned in the dissipation channel; and
a cover plate disposed to cover the body, the cover plate including an air discharge portion to discharge air that has passed through the air channel, and
a thermoelectric element disposed between the dissipation heat sink and the cover.

19. The foothold of claim 18 , wherein the foothold further includes at least one fin protruding downward from a bottom surface of the cover plate and positioned in the air channel.

20. The foothold of claim 18 , wherein the air channel comprises a plurality of air channels and the heat dissipation channel is disposed between the plurality of air channels.
