BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermostat apparatus used for performing a chemical reaction, stirring, mixing, etc. under a required thermostat.

[0002]

2. Description of the Related Art A device shown in FIG. 2 is conventionally known as this type of device, and will be described with reference to FIG. That is, in the figure, 51 is a constant temperature bath having a required volume,
Reference numeral 52 denotes a stirring blade attached to the thermostat 51 via a required mounting bracket, reference numeral 53 denotes a motor for rotating the stirring blade 52, and reference numerals 54 and 55 denote heaters provided in the thermostat 51. The heating element 54 and the cooling element 5
Numerals 5 operate in conjunction with each other via an automatic temperature controller (not shown). In addition, A denotes a bath liquid composed of water or the like filled in the thermostat 51.

[0003] The conventional example constructed as described above is a motor 5
While the stirring blade 52 is rotated at a constant speed by the operation of 3, the heating element 54 and the cooling element 55 are operated in conjunction with each other, and the bath A in the constant temperature bath 51 is kept at a predetermined temperature.
Then, the substance contained in a required container is put into a thermostat 51 by a conventional method, and a chemical reaction, stirring, mixing, and the like are performed.

[0004]

The above-mentioned prior art is compact and can be used very easily, but on the other hand, the heating element 54 and the cooling element 55 are provided in the thermostat 51 to directly supply the bath liquid A. Since the temperature is controlled by heating and cooling, the temperature difference at the time of temperature control tends to be large, and it is very difficult to always maintain a uniform temperature. Further, the stirring blade 5 together with the heating element 54 and the cooling element 55 are used.
2 is provided directly in the constant temperature bath 51,
In addition to the remarkable reduction in the effective use space in the case 1, there is a drawback that the reaction container and the like are easily damaged by contact.

[0005] This invention solves the conventional problems at a glance and greatly increases the effective use space in the thermostatic bath.
It is an object of the present invention to provide a thermostatic bath apparatus which can not only keep the bath liquid at a constant temperature at all times, but also does not cause damage to the reaction vessel and the like.

[0006]

That is, in the present invention, a regulating bath 2 is connected to a thermostatic bath 1 via a liquid feed / reflux pipe 3/11 so as to freely circulate a bath liquid. The heating body 8 and the cooling body 9 are provided internally, and a substantially cap-shaped jammer plate 4 having a required diameter and having a through hole 5 is attached to a leading end of the liquid sending pipe 3 located in the adjustment tank 2, and A required stirring blade 6 is provided in the jammer plate 4 so as to correspond to the liquid feed pipe 3.

[0007]

Function The bath A in the thermostatic bath 1 is sequentially fed into the adjusting bath 2 through the feed pipe 3, and the heating element 8 and the cooling element 9 are operated in conjunction with each other while being stirred by the stirring blades 6 in a vortex shape. After being adjusted to a predetermined temperature, it is returned to the thermostat 1 again through the reflux pipe 11 and circulated.
The bath A in the thermostat 1 is always kept at a constant temperature.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention. Reference numeral 1 denotes a constant temperature bath having a required volume whose outside is surrounded by a heat insulating material, 2 denotes a regulating bath disposed under the constant temperature bath 1 and has an outside surrounded by a heat insulating material, and 3 denotes a bottom of the constant temperature bath 1. In the connected liquid feed pipe, the free end of the liquid feed pipe 3 is arranged horizontally at substantially the center in the adjustment tank 2. Reference numeral 4 denotes a substantially cap-shaped jammer plate attached to the tip of the liquid feed pipe 3, 5 denotes a required number of through holes formed at equal pitches on the outer peripheral wall of the jammer plate 4, and 6 denotes a liquid feed pipe 3. Stirring blades 7 arranged in the jammer plate 4 corresponding to the tips are motors for rotating the stirring blades 6. Reference numeral 8 denotes a heater such as a heater arranged in a spiral shape in the adjusting tank 2 so as to surround the free end of the liquid feed pipe 3, and 9 a spiral body to surround the outer periphery of the heater 8. A cooling body 10 provided with water or cold water as a cooling medium is a temperature sensor 10 provided in the upper part of the regulating tank 2, and the cooling body 9 and the heating body 8 are automatically detected by the temperature sensor 10. The temperature controllers (not shown) operate in conjunction with each other.
Reference numeral 11 denotes a reflux pipe that connects the upper part of the adjustment layer 2 and the upper end of the thermostatic chamber 1 through the lid 12 in a communicating manner.

In the embodiment configured as described above, the thermostat 1
The bath solution A in the inside is circulated through the adjustment layer 2 while being kept at a predetermined temperature. That is, the bath liquid A in the thermostat 1
Are sequentially fed into the jammer plate 4 of the adjusting tank 2 through the liquid feed pipe 3, and the heating element 8 and the cooling element 9 are operated in conjunction with each other while being swirled by the rotation of the stirring blade 6. Adjust to the prescribed temperature. The bath liquid A adjusted to a predetermined temperature is returned to the thermostat 1 again through the reflux pipe 11. Hereinafter, similarly, the bath solution A in the thermostatic bath 1 is circulated through the adjusting bath 2 while being kept at a predetermined temperature at a predetermined temperature, and is used for required applications as in the conventional example.

[0010]

Since the present invention is configured as described above, the bath solution A in the thermostatic bath 1 is sequentially fed into the adjusting bath 2 via the liquid feed pipe 3 and is stirred by the stirring blade 6 in a vortex flow. By operating the heating element 8 and the cooling element 9 in conjunction with each other while adjusting the temperature to a predetermined temperature, the heating element 8 and the cooling element 9 are returned to the thermostatic bath 1 again through the reflux pipe 11 and circulated.
The bath liquid A in the thermostat 1 is always kept at a constant temperature easily and
Not only can the temperature be kept constant, but also the stirring blade 6 and the heating element 8 are not directly installed in the temperature-controlled bath 1 unlike the conventional example.
In addition, it is possible to greatly increase the cost, and furthermore, there is no fear of damage to the reaction container and the like during use.
