Instant electric water heater with syncretic volume and the heating method

Abstract

The invention discloses a quick-heating and positive displacement integrated electric water heater and its heating method. The electric water heater comprises a cabinet, wherein a water inlet port and a water outlet port are provided on the cabinet. The invention is characterized in that a group of chambers for storing water is provided in the cabinet, and a guide hole is provided between each chamber; an electric heating membrane heater is provided outside the cabinet, one end of the electric heating membrane heater is communicated with the water inlet port of the cabinet via a circulating pump; the other end of the electric heating membrane heater is connected with water source via an automatic switch; the water outlet port of the cabinet is connected with the water utilization pipe of the electric water heater via the electric heating membrane heater; and a temperature detector is provided in the cabinet and connected with a control device for coordinating the operation of the electric heating membrane heater, circulating pump and automatic switch. The invention can meet the requirement of randomly supplying hot water, and has the advantages of convenient and rapid usage, good energy-saving effect, long service life, easy arrangement, high hot water supplying rate, and high safety.

Description

technical field [0001] The invention relates to an electric water heater, in particular to an electric water heater with integrated heating and volume and a heating method thereof. Background technique [0002] In the prior art, regardless of whether it is an electric water heater or a solar water heater, the inside of their pressurized water storage tank is a cavity structure. After the water tank is filled with hot water, when the hot water is used, cold water needs to be injected into the water tank at first, so that the hot water in the water tank can flow out by the pressure of the cold water. Since cold water needs to be continuously added to the water tank, the added cold water will quickly mix with the hot water in the original water tank, causing the temperature of the hot water in the water tank to drop rapidly. Therefore, in actual use, only about 60% of the entire water tank volume is heated. Water can be utilized, causing a huge waste of heat. At present, the ...

AI Technical Summary

Problems solved by technology

Therefore, limited by the volume, it is often only enough for one or two people to bathe with water, and the temperature drops and changes greatly when using water, which brings great inconvenience and waste to users.

Considering the overall volume factor of the water heater, the insulation layer is generally about 2cm, the insulation effect is relatively poor, and the heat loss is large

[0005] 2. The high temperature on the surface of the electric heating tube is easy to age and scale, which will inevitably lead to a decline in heating power, and the electric heating tube is easily damaged, which reduces the service life of the whole machine

[0006] 3. The existing volumetric electric water heater has a single shape and is a cylinder, which needs to be hoisted, which makes installation difficult, takes up a lot of space, and affects the effect of home decoration

[0007] 4. It is difficult to ensure the safety of water and electricity mixing all the time. Although the protective plug and the anti-electricity wall leak-proof device are used, the potential safety hazard cannot be fundamentally eliminated, and personal injury accidents occur from time to time.

[0008] 5. Considering power saving, hot water cannot be guaranteed 24 hours a day, causing inconvenience to home life

[0009] 6. The service life of the liner is limited

Equivalent to 5 to 7 horses of electric power, the wire diameter of the configuration wire is 4mm 2 Above, this will greatly increase the cost of the entire power system, reduce safety, and it is difficult to guarantee product life

Due to the existence of these serious defects, it is an important reason for the low user recognition rate in the market

[0012] 2. If the power is below 3000W, it is suitable for conventional home configuration, the power consumption is 10 amps, and the wire diameter is 2.5mm 2 , the instant heating temperature does not reach the ideal water temperature, usually it can only be used as daily water, and cannot be used for bathing first, especially when the room temperature is below 20°C, and the season with normal temperature at 20°C generally accounts for three-quarters of the year. time

Therefore, instant electric water heaters with a power below 3000W cannot meet the requirements.
