Abstract
The utility model belongs to a temperature controller used on a high-end water heater, which comprises a temperature controller body, wherein two terminals are arranged on the upper part of the temperature controller body, and potting resin is filled around the terminals and in the open space on the upper part of the terminals; the resin shell is arranged on the outer side of the temperature controller body, and the metal outer cover is arranged at the lower end of the temperature controller body and is riveted with the outer side of the lower part of the resin shell; the lower part of the left end of the resin shell is provided with a small groove which is communicated with the annular groove; an opening is arranged at the joint of the upper end of the small groove and the metal outer cover. The upper part of the utility model is provided with the potting resin, and the lower part is provided with the sealing ring, which can completely play a role of sealing; and the high-pressure air in the temperature controller can be released when high-temperature test is carried out, so that the temperature controller is ensured not to burst, deform, distort and the like.
Description
Technical Field
The utility model belongs to temperature controller, in particular to temperature controller for high-end water heater.
Background
In some high-end water heater industries, although the temperature is about 100 ℃, an important test index is provided for a sealing temperature controller used by a water heater, namely the sealing temperature controller is placed in an electric furnace, the temperature is increased to 250 ℃, the duration is 1 hour, and the product is not burst, deformed and twisted; however, when the temperature of the common sealed temperature controller rises to 250 ℃, due to the sealing, the gas inside the temperature controller can expand violently, which causes the temperature controller to burst or deform and distort, which is not desirable; if the temperature controller is not sealed, the temperature controller cannot play a sealing role when being normally used, insulation breakdown is easy to occur in a damp and hot environment, and certain potential safety hazards exist.
Disclosure of Invention
The invention aims to overcome the technical defects and provide a temperature controller for a high-end water heater.
The utility model provides a technical problem, the technical scheme who adopts is: a temperature controller used on a high-end water heater comprises a temperature controller body, wherein two terminals are arranged at the upper part of the temperature controller body, and potting resin is filled in the open spaces at the periphery and the upper part of the terminals; the resin shell is arranged on the outer side of the temperature controller body, and the metal outer cover is arranged at the lower end of the temperature controller body and is riveted with the outer side of the lower part of the resin shell; the lower part of the left end of the resin shell is provided with a small groove which is communicated with the annular groove; an opening is arranged at the joint of the upper end of the small groove and the metal outer cover.
The beneficial effects of the utility model are that, the utility model discloses there is potting resin and lower part to have under the effect of sealing washer on whole sealed temperature controller's upper portion, in temperature controller self work, play sealed effect completely, and when putting whole temperature controller into electric stove, when heaing up to 250 ℃, along with the rising of temperature, the inside atmospheric pressure of temperature controller crescent, gradual outside inflation, thereby the sealing washer some will be crowded to play carminative effect in the little recess, temperature controller just can not take place to burst, the condition such as distortion.
Drawings
The following description is made in detail by way of example with reference to the accompanying drawings.
FIG. 1 is a front view of a temperature controller for use on a high-end water heater.
In the figure: 1-a metal housing; 2-small groove; 3-opening; 4-a resin shell; 5-potting resin; 6-terminal; 7-temperature controller body; 8-sealing ring; 9-annular groove.
Detailed Description
In the embodiment, referring to the attached drawings, the temperature controller used on a high-end water heater comprises a temperature controller body 7, wherein two terminals 6 are arranged at the upper part of the temperature controller body 7, and potting resin 5 is filled at the periphery and the upper part of each terminal 6; the resin shell 4 is arranged on the outer side of the temperature controller body 7, the metal outer cover 1 is arranged at the lower end of the temperature controller body 7 and is riveted with the outer side of the lower part of the resin shell 4, and the temperature controller is characterized in that an annular groove 9 is arranged at the lower end of the resin shell 4, and a sealing ring 8 is arranged in the annular groove 9; the lower part of the left end of the resin shell 4 is provided with a small groove 2, and the small groove 2 is communicated with an annular groove 9; an opening 3 is arranged at the joint of the upper end of the small groove 2 and the metal outer cover 1.
The utility model discloses a theory of operation is: when the sealed temperature controller to be tested is placed in an electric furnace and heated to 250 ℃, the air pressure in the temperature controller gradually increases along with the rise of the temperature and gradually expands outwards, a small part of the sealing ring 8 is extruded into the small groove 2 to play a role in exhausting, and the temperature controller cannot crack, deform, distort and the like; in normal use, although external moist air or water can enter the small groove 2 through the opening 3 due to the sealing function of the sealing ring 8, the moist air or water cannot enter the temperature controller body 7 from the opening 3 due to the function of the sealing ring 8; the potting resin 5 is filled at the terminal 6 at the upper part of the temperature controller body 7, so that the temperature controller body 7 is ensured to be completely in a closed environment, and the temperature controller can be safely used in a humid and submerged environment.
The above description is only a preferred embodiment of the present invention, but the present invention is not limited thereto, and can also be used in similar sealing products, and all the mechanisms belonging to the present invention should be covered within the protection scope of the present invention.
