Embodiment 1

[0026] Embodiment 1: As shown in Figure 1, Figure 2 and Figure 3, the energy-saving instant electric heating device of this embodiment includes a non-metallic water pipe 5, an electric heating wire 12 wound on the non-metallic water pipe and a water clamp capable of absorbing heat set. The non-metallic water pipe 5 is a thin-walled circular pipe with a smooth inner surface, which is made of special glass that is resistant to high temperature and large temperature difference without breaking, and has excellent insulating properties.

[0027] The water jacket includes a casing 10 and a casing 13, a water gap is left between the casing 10 and the casing 13, and sealing plugs 17 are arranged at both ends of the casing 10 and the casing 13. A sealing ring 8 is provided between 17 and the casing 10, and a water inlet 7, a water outlet 15 and an exhaust port 1 are provided on the casing 13. Between the sleeve pipe 10 and the water pipe 5, there is a gap where the heating wire 12 and...

Embodiment 2

[0030] Embodiment 2: As shown in FIG. 4 and FIG. 5 , this embodiment is a simplification of Embodiment 1, and the shell 13 in Embodiment 1 is eliminated, and other requirements are the same as Embodiment 1. The water flow enters from the lower end of the water pipe 5 during the operation of this embodiment, and the water flow flows out from the upper end of the water pipe 5 after being gradually heated to the required temperature during the upward flow in the water pipe.

[0031] FIG. 7 is a schematic structural view of a water dispenser equipped with an instant electric heating device 25 of this embodiment. 7, the inlet of the electromagnetic valve 23 is connected to the water outlet of the water dispenser bucket through the water pipe 24, the outlet of the electromagnetic valve 23 is connected to the inlet (lower end) of the heating device 25, and the outlet (upper end) of the heating device 25 is connected to drinking water Machine faucet 21. When in use, turn on the power...

Abstract

The invention relates to an energy-saving instant heating electric-heat device, comprising a non-metal water pipe, an electric-heat wire twisted on the non-metal water pipe and a water leg could absorb heat. When the device is operated, the normal temperature water firstly flows inside the water leg, the water is gradually preheated by the heat leaked via the electric-heat wire, the water preheated go to the water pipe, the water is gradually reheated by the electrical-heat wire when the water is flowing, when the water flows to the outlet of the heat device, the water temperature reaches the needed temperature. The distinctive character is that the heat speed is high, energy-saving, and safe and deposition would not be easy to form. The device is mainly applied in the instant heating drinking machine, to heat the water flows inside. The invention can be used in the devices that need to instantaneously heat the flowing liquids.

Description

technical field [0001] The invention relates to the technical field of liquid heating, in particular to an energy-saving instant heating electric heating device. Background technique [0002] The instant water dispenser has many advantages, for example, it completely overcomes the phenomenon of repeated heating of ordinary water dispensers, the water quality is fresh, and there is almost no energy consumption during standby. Such a water dispenser is disclosed in "Quick Electric Heating Water Dispenser" as Chinese Patent No. 200410089171.2. However, this water dispenser still has some places that need to be improved, especially the instant electric heater used therein. The electric heater is formed by the water pipe and the electric heating pipe through the casting body, which obviously has the following problems: [0003] 1. The surface temperature of the electric heater may exceed 200°C during operation, and there is no insulation layer, so the fire hazard is very large;...
