Abstract
A kiln including a stove and a heat source wherein the stove includes a cavity, an entry, and an air outlet. The cavity includes a front section communicating with the entry, a rear section disposed away from the entry, and a middle section disposed between the front section and the rear section. A top wall surface of the front section tilts downwardly toward the entry, and a top wall surface of the rear section tilts downwardly from the middle section toward a direction away from the entry. The air outlet is located between a top of the front section and the entry. The heat source is disposed in the rear section and includes a heating assembly for generating heat. The heating assembly is located at a position higher than a half of a distance between a top and a bottom of the middle section of the cavity.

A kiln, comprising:
- a stove, including a cavity, an entry, and an air outlet, wherein the cavity includes a front section, a middle section, and a rear section;
- the front section communicates with the entry;
- the middle section is disposed between the front section and the rear section;
- the rear section is away from the entry;
- a top wall surface of the front section tilts downwardly toward the entry;
- a top wall surface of the rear section tilts downwardly from the middle section toward a direction away from the entry;
- the air outlet is located between a top of the front section and the entry;
- a heat source, disposed in the rear section of the cavity and including a heating assembly adapted to generate heat for heating the cavity, wherein the heating assembly is located at a position which is higher than a half of a distance between a top and a bottom of the middle section of the cavity;
- and
- an exhaust pipe, wherein the stove includes a chamber, an air guide structure, and a heat storage member;
- an interior of the chamber forms the cavity, and the chamber includes the entry and the air outlet;
- the air guide structure is disposed at the top of the front section of the cavity, and the air guide structure communicates with the air outlet;
- the exhaust pipe is located above the air guide structure;
- the heat storage member covers an exterior of the cavity which is corresponding to the top of the front section of the cavity, and contacts the air guide structure;
- wherein the stove includes a thermal insulation structure;
- the thermal insulation structure covers an exterior of the cavity which is corresponding to the rear section and the middle section so as to make a temperature of the middle section is higher than that of the front section;
- wherein the thermal insulation structure includes a heat conduction layer, a heat storage layer, and a reflection layer;
- the heat conduction layer contacts the cavity;
- the heat conduction layer is disposed between the reflection layer and the heat conduction layer;
- a thermal conductivity of the heat conduction layer is greater than that of the heat storage layer;
- wherein the thermal insulation structure further includes another reflection layer and a thermal insulation layer;
- the thermal insulation layer is disposed between the reflection layer and said another reflection layer;
