Problems solved by technology

[0003] Conventional electric heating devices are mostly installed in the middle of the inner cavity of the inner tank of the water heater. The electric heating tube heats the water stored in the entire inner tank, and the water stored in the inner tank will heat up as a whole, which causes the water temperature to rise slowly, so , conventional water heaters fail to achieve the effect of quickly outputting hot water
Secondly, especially solar water heaters, no matter what the weather is, will preheat the water in the inner tank to a certain extent. If the water consumption is not large, the electric heating device will still heat the water in the inner tank, which will cause a lot of energy consumption. waste
[0004] Nowadays, electric heating devices of electric water heaters or solar electric water heaters are required in the industry to have a high speed heating and hot water collection effect. Therefore, product designers and manufacturers adopt the following electric auxiliary heating or heat preservation methods to improve the speed of electric heating devices Thermal performance and hot water collection effect: (1) Increase the power of the electric heating tube, but the method of simply incre

Embodiment 1

[0022] according to Figure 1 to Figure 3 As shown, it is the best embodiment of the present invention, the solar water heater of the present invention uses fast electric auxiliary heating device, and it is applied to the cold water heating of electric water heater or solar water heater. The present invention includes an inner container 1 of the water heater and a water inlet pipe 2 and an outlet pipe 3 connected to the inner cavity of the inner container 1. The inner container 1 is generally made of steel and has a horizontal structure, and the water inlet pipe 2 passes through the bottom of the inner container 1. Into the bottom of the inner cavity of the inner tank 1 to supply cold water to the inner tank 1, while the outlet pipe 3 passes out from the top of the inner cavity of the inner tank 1 to the outside of the inner tank 1. Since hot water is less dense than cold water and floats up, Therefore, the water inlet port 31 of the water outlet pipe 3 is generally located at...

Embodiment 2

[0027] see Figure 4 , this embodiment is another embodiment of the present invention, the structure of this embodiment is basically the same as the structure of the above-mentioned preferred embodiment, the slight difference is that: the heat collecting and guiding tube 5 can also be a straight tube structure, it is set Outside the electric heating tube 4, it extends straight to the side of the water inlet port 31 of the water outlet pipe 3, and it can extend obliquely upward from the central position of the electric heating tube base 8 to the side of the water inlet port 31 of the water outlet pipe 3. The mode is more in line with the natural floating characteristics of hot water. After being heated, the water can naturally go upward along the heat collecting and guiding tube immediately, so that the hot water in the heat collecting and guiding tube 5 can be quickly guided to the inlet of the outlet pipe 3. Water port 31.

Abstract

The invention discloses a rapid electric auxiliary heating device for a solar water heater. The heating device comprises an inner container of the water heater, a water inlet pipe, a water outlet pipe and a heat accumulation guide flow cylinder, wherein the water inlet pipe and the water outlet pipe are both communicated with the inner cavity of the inner containner; the inner cavity of the inner container is provided with an electric heating tube; the heat accumulation guide flow cylinder is sleeved on the electric heating tube; the heat accumulation guide flow cylinder is provided with a water outlet; and the water outlet is positioned at the side of a water inlet port of the water outlet pipe. The heating device provided by the invention has the advantages that on the basis of not increasing the power of a heating pipe, the effect of rapid hot water generation of the water heater is realized, the structure is simple, the heat accumulation effect of hot water is good, and rapid high hot water output volume is reached; and when hot water is not used,, the temperature of the hot water at the middle and upper part of the inner container rises through the heat exchange of the hot water gathered close to the water outlet pipe to perform preheating, thus semi-inner container heating can be realized, and the use performance of an electric water heater or the solar water heater is improved greatly.

Description

technical field [0001] The invention relates to the field of electric heating products of a solar electric water heater, which is installed in an electric water heater or an inner tank of a solar electric water heater for heating cold water, in particular to a fast electric auxiliary heating device for a solar water heater. Background technique [0002] At present, both electric water heaters and solar electric water heaters are equipped with electric heating devices: the whole working process of the former electric water heater relies on the electric heating device to heat the cold water; When using solar electric water heaters in seasons or areas with insufficient sunshine, in order to maintain the quality and continuity of hot water supply and enable solar electric water heaters to be used around the clock throughout the year, electric heating devices are also required. [0003] Conventional electric heating devices are mostly installed in the middle of the inner cavity...
