Abstract

The utility model discloses a dustbin, which comprises a box body, a DC power supply and a semiconductor refrigerating sheet, wherein the refrigerating sheet is positioned at the bottom part of the dustbin and is electrically connected with the DC power supply. The utility model has the main design scheme that the semiconductor refrigerating sheet is adopted, the semiconductor refrigerating sheet has higher thermal electric potential after being electrified, the refrigerating effect is good, the temperature can be fast reduced, and the garbage in the dustbin can not easily go bad and get rotten.

Description

A kind of rubbish container

Technical field

The utility model relates to a kind of rubbish memory storage, particularly relates to a kind of rubbish container.

Background technology

In the rubbish container rubbish rotten, rot, give off an unpleasant smell, contaminated environment, people generally adopt the way of timely cleaning rubbish.But at summer or the high environment of temperature, rubbish is very easily rotten, rotten, produces niff, and untimely cleaning can influence the attractive in appearance of living environment.

The utility model content

The utility model has overcome above-mentioned technical deficiency, and a kind of novel dustbin that can slow down rotten, the rotten speed of rubbish is provided.

For achieving the above object, the utility model adopts following technical proposals.

The utility model is a kind of rubbish container, comprise casing, it is characterized in that also comprising semiconductor chilling plate and direct supply, described semiconductor chilling plate is by a plurality of double-type P-type semiconductors and N-type semiconductor, metallic conductor and insulating ceramic film are formed, described a plurality of double-type P-type semiconductor and N-type semiconductor are arranged, and be connected in series by the described metallic conductor that polylith is attached at described P-type semiconductor and N-type semiconductor both ends of the surface, two described metallic conductors of described direct supply and head and the tail are electrically connected, fit with one deck insulating ceramic film respectively in the described metallic conductor outside, that side that the head and the tail metallic conductor of described semiconductor chilling plate is electrically connected with described direct supply is away from described casing, and opposite side is close to described bottom half.

Above-mentioned rubbish container, the semiconductor chilling plate two ends have high thermo emf after energising, and refrigeration effective can prevent that the rubbish in the rubbish container is rotten fast, rot, and beautifying of living environment played a positive role.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is elaborated:

Fig. 1 the utility model rubbish container embodiment.

The specific embodiment

Describe in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:

Fig. 1 shows the embodiment of the utility model rubbish container.As shown in Figure 1, the utility model rubbish container, comprise casing 3, semiconductor chilling plate 1, direct supply 2, this semiconductor chilling plate is by a plurality of double-type P-type semiconductors 11 and N-type semiconductor 12, metallic conductor 13 and insulating ceramic film 14 are formed, a plurality of double-type P-type semiconductors 11 and N-type semiconductor 12 are arranged, and be connected in series by the metallic conductor 13 that polylith is attached at P-type semiconductor 11 and N-type semiconductor 12 both ends of the surface, two metallic conductors 13 of direct supply 2 and head and the tail are electrically connected, fit with one deck insulating ceramic film 14 respectively in metallic conductor 13 outsides, that side that the head and the tail metallic conductor 13 of this semiconductor chilling plate 1 is electrically connected with direct supply 2 is away from casing 3, and opposite side is close to casing 3 bottoms.

The utility model rubbish container gains enlightenment according to " peltier effect " and makes." peltier effect " is to be found by French physicist Pa Er card.He finds respectively to connect a bismuth silk at two of copper wire, again two bismuth silks is received respectively on the both positive and negative polarity of direct supply, and after the energising, a joint heating, another joint turns cold, and this phenomenon is called as " peltier effect ".The physical principle of " peltier effect " is: charge carrier moves in conductor and forms electric current, because charge carrier is in different energy levels in different materials, when it from high level when low-lying level is moved, will discharge surplus heat, show as and heat, otherwise, just need to absorb heat, show as refrigeration.The utility model rubbish container has overcome rotten, the rotten fast easily shortcoming of rubbish in traditional rubbish container, according to the physical principle of " peltier effect ", adopted semiconductor chilling plate, it has high thermo emf, good refrigeration effect, can in time lower the temperature, prevent that rubbish is rotten, rot.

Claims

1. rubbish container, comprise casing, it is characterized in that also comprising semiconductor chilling plate and direct supply, described semiconductor chilling plate is by a plurality of double-type P-type semiconductors and N-type semiconductor, metallic conductor and insulating ceramic film are formed, described a plurality of double-type P-type semiconductor and N-type semiconductor are arranged, and be connected in series by the described metallic conductor that polylith is attached at P-type semiconductor and N-type semiconductor both ends of the surface, two described metallic conductors of this direct supply and head and the tail are electrically connected, fit with the described insulating ceramic film of one deck respectively in the described metallic conductor outside, that side that the head and the tail metallic conductor of described semiconductor chilling plate is electrically connected with described direct supply is away from described casing, and opposite side is close to described bottom half.
