Abstract
Description
Technical Field
[0001] This utility model relates to an all-glass liquid heating container. Background Technology
[0002] Current technologies, such as Figure 3 As shown, an all-glass liquid heating container includes an all-glass liquid heating container 1, a circular base 2, an electric heating plate 3, a coupler 4, a fuse 5, a snap-action thermostat 6, and two temperature sensors 7. The electric heating plate and the all-glass liquid heating container 1 are bonded together with thermally conductive gel. The snap-action thermostat detects the temperature of the electric heating plate to prevent dry burning, while the two temperature sensors detect the temperature of the bottom plate of the all-glass liquid heating container 1. The problem is that the snap-action thermostat operates frequently. Due to the low thermal conductivity and slow heat transfer rate of glass and thermally conductive gel, there is a significant lag in monitoring the container temperature, making it difficult to accurately reflect the actual internal temperature during cooking and failing to effectively prevent dry burning. This may lead to excessively high temperatures between the heating plate aluminum plate and the glass container, thereby damaging the glass body and the thermally conductive materials. Utility Model Content
[0003] The purpose of this invention is to provide an improved all-glass liquid heating container with temperature control, which features a temperature sensor that directly detects the temperature of the heating plate, accurately controls the temperature of the heating plate, and shortens the boiling time.
[0004] This invention is implemented as follows: an improved temperature-controlled all-glass liquid heating container, characterized in that it includes an all-glass liquid heating container, an electric heating plate, a coupler, a fuse, a snap-action temperature controller, a plate temperature sensor, a container temperature sensor, and a main control board.
[0005] An electric heating plate includes a heat-conducting plate body and a heating element disposed on the heat-conducting plate;
[0006] The electric heating plate and the base plate of the all-glass liquid heating container are bonded together with thermal conductive gel. The snap-action thermostat works with the heating plate body. The plate temperature sensor detects the temperature of the heating plate body. The container temperature sensor is attached to the base plate of the all-glass liquid heating container and detects the container temperature. The plate temperature sensor works with the main control board to control the temperature of the electric heating plate and prevents dry burning. It also takes priority over the snap-action thermostat.
[0007] The improved temperature control all-glass liquid heating container is characterized in that the plate temperature sensor controls the temperature of the heat-conducting plate and the anti-dry-burning temperature to be lower than the activation temperature of the snap-action temperature controller.
[0008] The improved temperature control all-glass liquid heating container is characterized in that: the temperature of the heat-conducting plate is less than 230°C, which is the anti-dry-burning activation temperature point.
[0009] The operating temperature of the snap-action thermostat is less than 250℃.
[0010] The improved temperature control all-glass liquid heating container is characterized by the fact that the plate temperature sensor, container temperature sensor and main control board work together to control and reflect the liquid temperature inside the all-glass liquid heating container.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0018] like Figure 1 , Figure 2 As shown, an improved temperature-controlled all-glass liquid heating container includes an all-glass liquid heating container 1, an annular base 2, an electric heating plate 3, a coupler 4, a fuse (not shown), a snap-action temperature controller, a plate temperature sensor 51, a container temperature sensor 52, and a main control board.
[0019] The electric heating plate 3 includes a heat-conducting plate body and a heating tube disposed on the heat-conducting plate, which is a known technology and will only be briefly described here;
[0020] The electric heating plate 3 and the base plate of the all-glass liquid heating container 1 are bonded together with thermally conductive gel. The annular seat 2 is arranged around the electric heating plate 3 and fixed to the base plate of the all-glass liquid heating container 1. The snap-action thermostat cooperates with the heat-conducting plate body. The plate temperature sensor 51 detects the temperature of the heat-conducting plate body. The container temperature sensor 52 is set on the annular seat 2 and detects the container temperature. The plate temperature sensor 51 and the main control board control the temperature of the electric heating plate 3 and prevent dry burning. It takes priority over the snap-action thermostat.
[0021] The plate temperature sensor 51 can regulate the temperature of the electric heating plate in real time before the snap-action thermostat trips. For example, if the trip point of the snap-action thermostat is less than 250°C, the plate temperature sensor 51, in conjunction with the circuit board program, monitors and controls the temperature of the heating plate to be less than 230°C. This avoids or significantly reduces the number of trips of the snap-action thermostat during boiling water, thereby achieving faster and more precise temperature control and overheat protection, effectively shortening the boiling time.
[0022] The plate temperature sensor 51, the container temperature sensor 52, and the main control board work together to control and reflect the liquid temperature inside the all-glass liquid heating container 1.
[0023] The plate temperature sensor 51 controls the temperature of the heat-conducting plate and the anti-dry-burning temperature to be lower than the operating temperature of the snap-action thermostat. This design prevents frequent activation of the snap-action thermostat and shortens the heating time.
[0024] The temperature of the heat-conducting plate body is less than 230℃, which is the anti-dry-burning temperature point of the plate temperature sensor 51.
[0025] The operating temperature of the snap-action thermostat is when the temperature of the heat-conducting plate is less than 250℃.
[0026] As a further improvement of this utility model: the coupler 4, fuse, disc temperature sensor 51 and snap-action temperature controller are integrated into one unit to form an integrated temperature control component.
[0027] The all-glass liquid heating container is made of high borosilicate glass. Manufacturers of all-glass liquid heating containers and thermal conductive gel recommend using temperatures below 250 degrees Celsius. This invention employs a control method that protects the all-glass liquid heating container and thermal conductive gel, extending their service life.
[0028] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
