Constant temperature water bath pot

The invention discloses a constant temperature water bath pot, which comprises an outer shell with an opening at the upper end, an inner gallbladder in the outer shell, a top plate at the opening of the outer shell, two ends of the top plate connected to the inner wall of the inner gallbladder, a heater in the inner gallbladder, a heater connected with a temperature controller and a switch through an electric wire, and a temperature controller and a switch are placed on the outer shell. One end of the inner liner is connected with an inlet pipe, the other end of the shell is connected with an outlet pipe, and the top plate is provided with four large holes of the same size. At the same time, there are several hole caps of different diameters above each large hole. The invention has the advantages of safety, reliability, applicability to containers of various diameters and precise temperature control.

[0001] The invention relates to a water bath pot, in particular to a constant temperature water bath pot. Background technology

[0002] The traditional thermostatic water bath pot adopts mechanical temperature control methods such as glass or bimetal plate, which can not accurately control the temperature at fixed points. Moreover, the diameter of the hole cover is single, and it is not suitable for containers of various diameters, and the practical range is small. summary of the invention

[0003] The purpose of the present invention is to overcome the above shortcomings and provide a safe and reliable constant temperature water bath pot suitable for vessels of various diameters and sizes.

[0004] The object of the present invention is realized by the following technical scheme: a constant temperature water bath pot, including an outer shell with an opening at the upper end, an inner gallbladder at the inner shell, a roof at the opening of the shell, two ends of the top plate connected to the inner wall of the inner gallbladder, a heater in the inner gallbladder, and a temperature control through electric wires connected by the heater. Instrument and switch, temperature controller and switch are placed on the shell, one end of the inner tank is connected with the intake pipe, the other end of the shell is connected with the outlet pipe, the top plate is equipped with four large holes of the same size, and the top of each large hole is equipped with multiple hole caps of different diameters.

[0005] The drawings are illustrated as follows: Fig. 1 is the schematic diagram of the present invention; Fig. 2 is the overhead view of the present invention; Fig. 1 is labeled as 1-case, 2-roof, 3-inner gallbladder, 4-heater, 5-temperature controller, 6-switch, 7-inlet pipe, 8-Outlet pipe and 9-orifice cap.

[0006] Specific embodiments: In order to deepen the understanding of the present invention, the present invention will be further elaborated in connection with embodiments and drawings, which are only used to explain the present invention and do not constitute a limitation of the scope of protection of the present invention.

[0007] Fig. 1 shows an embodiment of the constant temperature water bath pot of the present invention, including an outer shell 1 with an opening at the upper end, an inner gallbladder 3 at the inner part of the outer shell 1, a top plate 2 at the opening of the outer shell 1, two ends of the top plate 2 connected to the inner wall of the inner gallbladder 3, a heater 4 inside the inner gallbladder 3, and a temperature controller 5 through wires. And switch 6, temperature controller 5 and switch 6 are placed on shell 1, one end of inner tank 1 is connected with inlet pipe 7, the other end of shell 1 is connected with outlet pipe 8, and the top plate 2 is equipped with four large holes of the same size. At the same time, the top of each big hole is equipped with several hole caps of different diameters.

[0008] When in use, the container containing liquid is filled into the hole on the top plate 2. The inner liner 3 is filled with water. The heater 4 at the bottom of the inner liner 3 is heated by opening switch 5. When heated to the specified temperature, the heater is no longer heated for heat preservation. When the water temperature is lower than the specified temperature, the heater continues to work. During the heating process, the water in the inner liner 3 is heated. When steam evaporates from the crevice, the water in the tank will be reduced, and water can be added through the intake pipe 7. The invention has the advantages of safety, reliability, applicability to vessels of various diameters and precise temperature control.
