Embodiment 1

[0025] refer to figure 1 , the instant thick-film heater of the present embodiment includes a container for storing water and a thick-film heater 2 installed in the container. The container is the kettle body 1 of an electric kettle, and the material of the container can be selected from stainless steel and aluminum alloy. Material manufacturing can also be molded with food-grade organic polymer materials, mainly to achieve direct connection or indirect connection with the thick film heater 2 . The kettle body 1 includes the bottom plate 1.1 of the kettle body, and the thick film heater 2 is installed on the cross section of the kettle body 1. It is matched with the kettle body 1, and is also provided with a power supply base 3, and a temperature sensing tube and an anti-dry device are arranged in the container , The temperature sensing tube, the anti-dry heating device and the thick film heater 2 are all installed in the kettle body 1, and the thick film heater 2 is electrica...

Embodiment 2

[0031] refer to Figure 3-4 , the instant thick-film heater of the present embodiment is a water heater or a water dispenser, wherein the container is the outer wall 7 of the water heater or water dispenser, and the material of the container can be made of stainless steel or aluminum alloy, or can be made of food-grade organic polymer materials Molding manufacturing mainly depends on realizing the direct connection or indirect connection with the thick film heater 2 . The outer wall 7 is assembled by the front plate 7.4 and the back plate 7.5 to form a closed cavity, which is generally in the shape of a regular cuboid, but it can also be tightened on the container at the end of the hot water outlet as required, so that the upper part of the container The volume of the part is smaller than that of the lower part, which is similar to a triangular shape. If the upper part of the container is tightened, it will help the water heater or drinking fountain to quickly produce hot wate...

Abstract

The invention relates to an instant thick film heater which comprises a container and a thick film heater. The thick film heater comprises a heating substrate. A thick film circuit is printed on one side of the heating substrate. External contacts are arranged on the heating substrate. The container is provided with through holes for wiring of the thick film heater. A seal plate is hermetically arranged on the thick film circuit printed side of the heating substrate. An insulating layer is arranged on the seal plate. The seal plate is provided with wiring through holes for wring of the external contacts, the wiring through holes correspond to the external contacts in position, wiring parts are hermetically connected to the wiring through holes, and the other end of each wiring part is hermetically and fixedly connected with the corresponding through hole of the container. The thick film heater is suspended in the container through the wiring parts. The instant thick film heater is fully soaked in liquid to be heated, and accordingly heat exchange area is multiplied for the thick film heater and the liquid to be heated, heat generated by the thick film heater is utilized effectively and backward movement of the procedure of welding leads on the external contacts of the heating substrate is realized.

Description

technical field [0001] The invention relates to the technical field of electric heating devices for fluids, in particular to an instant thick film heater. Background technique [0002] At present, thick film thermal printing technology has gradually matured, and has the characteristics of good thermal conductivity, large heat dissipation area and high safety performance, but the efficiency and performance of fluid heating have not yet reached the design requirements for fully effective use. For example, the thick-film heater used to make instant water heaters in the prior art is generally fixed on the back plate of the instant water heater with a single heating plate, so as to avoid the gap between the thick-film circuit on the heating plate and the fluid to be heated. Contact, while ensuring the power supply requirements of the thick film heater and avoiding leakage. Another example is that the electric kettle in the prior art generally adopts the chassis heating mode, suc...
