The first embodiment is as follows:

referring to fig. 1-3, an energy-saving hot air circulation oven capable of utilizing waste heat comprises a box body 1, an air inlet pipe 2 communicated with the interior of the box body 1 is installed at the upper end of the box body 1, an air distribution plate 3 is installed on the inner wall of the box body 1, and an electric heating component 4 is installed on the inner wall of the box body 1. The revolving chute 5 has been seted up to the lateral wall of

box

1, and 5 internal seal of revolving chute rotates and is connected with carousel 6, and a plurality of stock chests 61 have been seted up to equidistant on the lateral wall of carousel 6, and the intussuseption of stock chest 61 is filled with the silica gel granule, and through-hole 611 has all been seted up to two relative inner walls of stock chest 61.

It should be noted that there is a certain resistance to the rotation between the rotating disk 6 and the rotary trough 5, so that the rotating disk 6 can be kept stable when the hot and humid air flows through the storage troughs 61 on the rotating disk 6, and the silica gel particles in the storage troughs 61 above can absorb sufficient moisture and then push the rotating disk 6 to rotate, so as to ensure that the moisture in the storage troughs 61 below can be evaporated completely in sufficient time.

Be equipped with in the box 1 with the inside communicating return air pipe 7 of rotary trough 5, the upper end of box 1 is installed with the inside communicating exhaust pipe 8 of rotary trough 5, the lateral wall of box 1 seted up with the inside communicating one-way venthole 9 of rotary trough 5, one-way venthole 9 only allows the air to discharge to one-way venthole 9 from stock chest 61 in, can specifically realize the one-way function of giving vent to anger at the venthole installation check valve.

The return air pipe 7, the exhaust pipe 8 and the one-way air outlet hole 9 are communicated with each other through holes 611 which are adjacent to each other, and the return air pipe 7 and the exhaust pipe 8 are symmetrically arranged along the vertical axis of the rotary groove 5.

This device is when using, install air-supply line 2 and exhaust pipe 8 respectively at circulating fan's the end of giving vent to anger and inlet end, the air that fan 2 blew into can be scraped interior discharge box 1 by the air inlet in, advance 3 water conservancy diversion of air distribution plate and flow in box 1 (the air flow direction is shown as the arrow in figure 1), after heating food, damp and hot air is discharged gyration groove 5 by return air pipe 7, discharge into behind the moisture in the air of stock chest 61 internal diameter silica gel granule absorption air by through-hole 611, get into circulating fan by exhaust pipe 8, so can carry out recycle with the waste heat of the air after the discharge, the heat that significantly reduces runs off, thereby shorten the baking time, also save a large amount of power consumption simultaneously.

As shown in fig. 2, when the hot and humid air continuously passes through the upper storage trough 61, the silica gel particles in the storage trough 61 absorb a large amount of moisture, and the overall mass of the silica gel particles is increased accordingly. Specifically, when in use, as shown in fig. 3, the return air pipe 7 and the exhaust pipe 8 can be communicated with the storage tank 61 on the left side above, after the whole mass in the storage tank 61 is increased, the rotary table 6 is pushed to rotate counterclockwise under the action of gravity, the storage tank 61 absorbing moisture is positioned right below the rotary table 6, and the storage tank 61 on the right side above is rotated to the left side above, so as to dry the discharged hot and humid air. The material storage tank 61 positioned right below the rotary disc 6 is close to the inside of the box body 1, the temperature of the material storage tank is high, and moisture absorbed by silica gel particles in the material storage tank 61 can be quickly evaporated and discharged from the one-way air outlet 9 in a high-temperature state. After the left stock chest 61 in top absorbs sufficient moisture again, can promote carousel 6 anticlockwise rotation again to can continuously circulate and carry out drying process to exhaust damp and hot air.

Example two:

referring to fig. 4-5, different from the first embodiment, the side wall of the box body 1 is provided with an annular groove 10, the annular groove 10 wraps the periphery of the box body 1, and after the residual heat air is discharged into the annular groove 10, a heat insulation layer formed by hot air can be formed. The air inlet end of the exhaust pipe 8 is arranged at the inner bottom of the annular groove 10, a spiral pipe 11 is communicated between the annular groove 10 and the rotary groove 5, and the spiral pipe 11 is communicated with the one-way air outlet 9 through a guide pipe 12. The liquid outlet end of the guide pipe 12 is arranged at the outer side of the one-way limiting position of the one-way air outlet hole 9, so that water flowing out along the guide pipe 12 can be prevented from flowing back to the material storage tank 61.

In this embodiment, the air dried by the silica gel particles in the storage tank 61 will flow through the spiral tube 11, and when the air flows along the spiral pipeline of the spiral tube 11, the moisture in the air which is not dried is greater than the gas mass due to the mass of the moisture, and will be subjected to a larger centrifugal force, and will be thrown onto the inner wall of the spiral tube 11, and will gradually condense on the inner bottom of the spiral tube 11 under the action of gravity, and finally will be discharged into the one-way air outlet 9 along the conduit 12 and discharged out of the box body 1. The drying degree of the air discharged into the circulating fan can be further improved, so that the wet air is prevented from damaging the circulating fan.

In addition, the air will get into ring channel 10 after being discharged by spiral pipe 11, so can form good heat preservation all around at box 1 to prevent that the heat of box 1 from outwards giving off, further reduce the heat loss in the box 1, further promote the energy-conserving effect of this device, waste heat air finally gets into in the circulating fan by exhaust pipe 8 and recycles.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
