Abstract
Provided is a thermostat with reduced temperature difference within the tank when a solution is being heat-treated. Stirring guides (114) for guiding a water-flow generated by a stirring bar (113) to both ends of a tank (106) in the longitudinal direction are disposed on the bottom of the tank (106). Thus, the water-flow generated by the stirring bar (113) is efficiently guided to both ends of the tank (106) in the longitudinal direction while keeping its momentum, and therefore a circulating water-flow for homogenizing the temperature of the water within the tank (106) can be effectively generated.

1-10. (canceled)
A bottom-side water conduit for a thermostat, comprising:
- an upper plate having four sides;
- two side plates respectively formed continuously and extending downward from two opposite sides of the upper plate;
- a shielding plate extending downward from one side of the upper plate and connected to the side plates;
- an inlet opening formed at the opposite side of the shielding plate;
- and
- an exit opening formed on the upper plate at the end on the side of the shielding plate.
A thermostat comprising:
- a tank adapted to contain a liquid, having a bottom surface thereof formed in a shape having a longitudinal direction and a transversal direction that are at right angles to one another and in which a length in the longitudinal direction is longer than a length in the transversal direction, and a side wall extending in the vertical direction from the bottom surface;
- a temperature changing unit arranged on the outer side of the tank and adapted to change the temperature of the liquid through the tank;
- a rotating body arranged within the tank on the bottom surface thereof;
- a drive unit adapted to rotary-drive the rotating body;
- and
- a bottom-side water conduit provided within the tank on the bottom surface thereof,
- wherein the bottom-side water conduit comprises an upper plate having four sides, two side plates respectively formed continuously and extending downward from two opposite sides of the upper plate, a shielding plate extending downward from one side of the upper plate and being connected to the side plates, an inlet opening formed at the opposite side of the shielding plate, and an exit opening formed on the upper plate at the end on the side of the shielding plate, and
- wherein the bottom-side water conduit is arranged in a position adjacent to the rotating body so that the shielding plates is oriented in the longitudinal direction of the tank.
A thermostat comprising:
- a casing including a first tank housing having a first tank, a second tank housing having a second tank and a third tank housing having a third tank, each of the first, second and third tanks being substantially the same shape and thermally separated from each other, wherein each tank is adapted to contain a liquid, a bottom surface thereof formed in a shape having a longitudinal direction and a transversal direction that are at right angles to one another and in which a length in the longitudinal direction is longer than a length in the transversal direction;
- and a side wall extending in the vertical direction from the bottom surface
- a temperature changing unit arranged on the outer side of the first tank and adapted to change the temperature of the liquid through the first tank;
- a rotating body arranged within the first tank on the bottom surface thereof;
- a drive unit adapted to rotary-drive the rotating body;
- and
- a bottom-side water conduit provided within the first tank on the bottom surface thereof,
- wherein the bottom-side water conduit comprises an upper plate having four sides, two side plates respectively formed continuously and extending downward from two opposite sides of the upper plate, a shielding plate extending downward from one side of the upper plate and being connected to the side plates, an inlet opening formed at the opposite side of the shielding plate, and an exit opening formed on the upper plate at the end on the side of the shielding plate, and
- wherein the bottom-side water conduit is arranged in a position adjacent to the rotating body so that the shielding plates is oriented in the longitudinal direction of the tank.
