Description
Technical Field
The invention belongs to the field of water heaters, and particularly relates to an electric water heater and a mode realization method thereof.
Background
A water heater is a device that increases the temperature of cold water to hot water over a period of time. According to different working principles, the water heater can be divided into a gas water heater, an electric water heater, a solar water heater, a magnetic water heater, an air energy water heater, a heating water heater and the like. The electric water heater has the advantages of no danger and pollution such as gas leakage, CO poisoning, waste gas emission and the like, no influence of weather conditions and the like, and is widely applied to China and south China. The existing electric water heaters have many types, but when the electric water heaters are used, cold water needs to be continuously supplied, namely the cold water enters the inner container, and hot water can flow out, and the defects exist, namely the hot water at 75 ℃ in the whole inner container is quickly fused with the hot water once the cold water enters, and the water temperature can be quickly reduced. The problem is that the electric heater needs to be electrified for a long time to heat, and when the hot water is used in daily use such as vegetable washing, dish washing and face washing, a small amount of hot water is used, and the electric heater needs to be electrified to heat, so that electricity and energy are wasted; if the power is turned off, the temperature of the water is lowered by the supplemented cold water, especially in winter. Therefore, if hot water can be discharged without supplementing cold water at the moment, namely when hot water is not used for showering, a great amount of cold water can be added into a tank of hot water without supplementing cold water for daily vegetable washing, dish washing, face washing and the like, water with corresponding temperature can be added according to the requirement, and the whole tank of hot water can be well utilized.
Therefore, in view of the problem that the electric water heater needs to supplement cold water to discharge hot water, if the electric water heater with the function of closing the water inlet valve can be provided, and the electric water heater is in a peak-valley electricity price mode, namely, the electric water heater is electrified and heated in a valley section (21:00-8:00), the water inlet valve is closed in a peak section (8:00-21:00), the heating is stopped, the whole container of hot water is generally enough to ensure daily hot water supply in one day, and the shower is enough in summer; when the shower is taken in a season with low air temperature, the water supplementing mode and the constant-power-on heating mode are used, so that the energy conservation is realized.
In addition, cold water supplemented by a common electric water heater is mixed with original hot water in the water tank quickly, so that when a shower is taken, although the electric heating pipe is always heating, the temperature of water in the tank also drops quickly, so that the fluctuation of the temperature of the water at an outlet is large, and the shower is influenced. Therefore, according to the thermodynamic principle of the hot water circulating fluid, the layout in the tank is designed, so that the cold and hot water exchange is more reasonable, the layering and the partitioning of cold water and hot water are realized, and the aim of reducing the large water temperature fluctuation is fulfilled.

Detailed Description
The invention is described in further detail below with reference to the accompanying drawings. Other aspects, features and advantages of the present invention will become apparent from the following detailed description, which, when taken in conjunction with the drawings, illustrate by way of example the principles of the invention.
As shown in fig. 1, the main body of the novel electric water heater is composed of an insulating layer 2, a first water temperature sensor 5, a second water temperature sensor 17, a first water level monitor 6, a second water level monitor 13, a water inlet pipe 12, an auxiliary hot water pipe 16, a hot water pipe 18, a ventilation valve 4, a reversing valve 11, a split-flow water inlet 10, an upper heating pipe 7 and a lower heating pipe 9.
A. B, C the three district separates through a horizontal baffle 3 and a vertical baffle 3, wherein the straight tube hole 8 of diameter 20mm is seted up to horizontal baffle 3 so that hot water arrives the B district from the A district, diameter 10 mm's snakelike return bend 15 is seted up to vertical baffle for the hot water convection in A district and C district, because the water pressure difference of two pipe imports department is less, and snakelike return bend can cause the loss of torrent kinetic energy, the straight tube cross section is 4 times of snakelike return bend cross section simultaneously, so the water yield through the straight tube is greater than the water yield through snakelike return bend. Circulation of one of the hot water, zone a → zone B → zone C → zone a, is easily achieved. The unilateral clearance between the hot water pipe 18 and the horizontal clapboard 3 is 5 mm. The serpentine elbow configuration is shown in fig. 4.
1. Temperature setting selection
After 60L of whole water in the container is heated to the highest heating temperature of 75 ℃, through professional detection equipment, when a better heat insulation material and a production mode are adopted, namely the whole outer heat insulation shell is formed by foaming polyurethane, under the condition of the ambient temperature of 25 ℃, the test records how long the water temperature needs to be reduced to 38 ℃. The longer the time, the better the heat preservation effect of the water heater, and as can be seen from the test result of fig. 7, the whole container of water is powered off after being heated to 75 ℃, and after 113 hours, which is equivalent to four and a half days, the water temperature is reduced to 38 ℃.
In terms of heating temperature setting, when used in a shower, a maximum heating temperature is generally set, such as 75 ℃. But is it best to set what temperature is used for hot water for daily use? The analysis was as follows:
on the one hand, the survival of bacteria at different temperatures according to the World Health Organization (WHO) is: death immediately above 70 ℃; 90% of the cells die within 2 minutes at a temperature of more than 60 ℃; 90% of the cells die within 80-124 minutes at about 50 ℃; survival but not reproduction at 48-50 ℃; the optimal growth temperature is 32-42 ℃. On the other hand, the higher the water temperature is, the faster the heat dissipation is, as can be seen from fig. 7, the faster the water temperature falls in the range of 75 ℃ to 60 ℃, and the slower the temperature falls below 60 ℃.
It follows that, as common daily use of hot water, it is recommended to set the heating temperature to 60 ℃, which not only can inhibit bacteria, but also can reduce heating time and heat loss speed, reduce energy consumption, and be economical and environment-friendly.
2. Specific working process
The novel electric water heater can provide two modes: the water tank structure can meet the requirement of continuous circulation rising of hot water, and is not easy to cause the problem of sudden drop of the water temperature at the water outlet of the hot water pipe after cold water is supplemented; and the mode of 'daily (non-water supplement)' is used for daily vegetable washing, tableware washing and rinsing, at the moment, the daily mode is started, the upper end vent valve 4 is opened when the solar water heater is used, the water tank is communicated with the atmosphere, hot water in the liner flows out from the hot water pipe 18 or the auxiliary hot water pipe 16, and at the moment, the water temperature is measured and displayed by the water temperature sensor II 17.
2.1 shower (refill) mode
When a 'shower (water replenishing)' mode is selected on the control panel 14, the control reversing valve 11 is communicated with a water inlet channel of tap water and a water tank, the vent valve 4 at the upper end is closed (the vent valve is normally closed), at the moment, cold water firstly enters the first-stage heating of the area A to be heated, the heated water circulates upwards and enters the area B through the partition plate 3, the heat transfer of the water in the water heater has two modes of heat conduction and convection heat transfer, mainly the convection heat transfer is adopted, the density of the cold water is higher than the density of the hot water, so that the cold water is on the lower hot water, and the horizontal partition plate 3 is adopted to ensure that the heat exchange of the hot water in the area B to the cold water in the area A is difficult, thereby realizing the layering effect and reducing. The hot water entering the zone B is further heated in a second stage, the water temperature is further increased, and the hot water flows out of the hot water faucet through the hot water pipe 18 and is mixed with cold water to be used for continuous water use such as showering. Because the hot water is upward, the hot water pipe 18 at the high position always leads out the higher water temperature. Water with lower temperature circulates downwards and enters the zone C from the gap between the hot water pipe 18 and the middle partition plate 3, the vertical partition plate 3 is used between the zone C and the zone A, the heat convection between the two zones can be effectively blocked, and the hot water partitioning is realized. Therefore, the water temperature in the B area is always kept at a higher and stable set temperature, and the water temperature is displayed and controlled by the water temperature sensor I5.
The mode is used for continuously using water for bathing and the like, hot water flows out of the hot water pipe 18, the reversing valve 11 is communicated with the water inlet pipe 12, cold water enters the water tank (inner container) from the water inlet pipe 12 through the shunting-type water inlet hole 10, and the shunting-type water inlet hole 10 is used for reducing impact and facilitating mixing with the hot water existing in the area A as soon as possible, so that the temperature is improved. The power is electrified, the vent valve 4 is closed (water leakage is prevented), and the upper heating pipe 7 and the lower heating pipe 9 are heated simultaneously. At the moment, the temperature of the water in the liner is measured and displayed by the upper water temperature sensor I5. The water tank structure meets the requirement of continuous rising circulation of hot water, and is not easy to cause sudden drop of water temperature after cold water is supplemented.
QSuction device＝cm(t-t0) (1)
QPut＝cm(t0-t) (2)
In the formula QSuction device-the amount of heat absorbed, J;
Qput-the heat evolved, J;
c-specific heat capacity (specific heat capacity of water 4.2X 10)3J/(kg·℃))，J/(kg·℃)；
t-water temperature after heat energy transfer, DEG C;
t0initial water temperature, deg.C.
The calculation is carried out by taking 50L hot water at 60 ℃ in the whole container as an initial value, every 3L hot water flows out, every 3L cold water at 10 ℃ is supplemented, and a relation curve of the temperature and the water inflow is obtained by calculation and fitting according to the formulas (1) and (2) (figure 8). 2.2 daily (non-Water supplement) mode
When the 'daily (non-water-replenishing)' mode is selected on the control panel 14, the water tank and the auxiliary hot water pipe 16 are connected in a control reversing way, at the moment, the water inlet channel of the water tank is communicated with the hot water pipe 18 through the auxiliary hot water pipe 16, and the tap water is not communicated with the water inlet pipe 12; meanwhile, the upper end vent valve 4 is opened, so that the water tank is communicated with the atmosphere, water in the water tank can flow out from the hot water pipe 18 or the auxiliary hot water pipe 16, and the function of discharging hot water without supplementing water is realized. Therefore, the whole tank of hot water can be well utilized under the condition of not supplementing cold water.
When the water tank is full of water, i.e., when the water level is high, the water in the water tank may flow down from the upper portion of the hot water pipe 18, and when the water level is lower than the height of the hot water pipe, the water in the water tank flows through the sub-hot water pipe 16 to the hot water pipe 18 through the divided-flow type water inlet hole 10 and then to the hot water faucet.
Is used for daily vegetable washing, tableware washing and gargling. At the moment, heating is stopped, the vent valve 4 is opened, the reversing valve 11 is communicated with the auxiliary hot water pipe 16 and the split-flow water inlet hole 10, and the tap water pipe is not communicated with the water inlet pipe 12 entering the water tank; the hot water in the water tank (inner container) flows out from the hot water pipe 18 or the auxiliary hot water pipe 16. At this time, the water temperature is measured and displayed by the second water temperature sensor 17. When the water level is lower than the second water level detector 13, the hot water is used up, the reversing valve 11 is communicated with the water inlet pipe 12, cold water enters the liner from the water inlet pipe 12, the water replenishing mode is switched to, and when the first water level detector 6 detects the water level, the vent valve is closed.
When the first water level sensor 6 detects that the water level is not higher than the heater, the water heater is in a protection state and does not heat even if the heating temperature is set, and dry burning is prevented.
The two modes of operation of the vent valve are shown in fig. 2, wherein (a) shows the vent valve state in the daily (non-refill) mode, and (b) shows the vent valve state in the shower (refill) mode. Two working mode structures of the reversing valve are shown in fig. 5, wherein (a) the diagram shows the state of the reversing valve in a shower (water replenishing) mode, and (b) the diagram shows the state of the reversing valve in a daily (water non-replenishing) mode. The two operating mode spools of the reversing valve are shown in figure 6.
The calculation of the formulas (1) and (2) shows that under the condition that the upper heating pipe 7 and the lower heating pipe 9 are not heated, a daily (non-water-supplementing) mode is adopted, 50L of hot water at 60 ℃ in the whole container and 10 ℃ of cold water can be mixed to obtain 125L of warm water at 30 ℃ (the temperature of common face washing is not higher than that of the face washing), and the requirements of daily household hot water for washing dishes, vegetables and the like can be met.
On the other hand, as shown in fig. 8, if the "shower (water supplement)" mode in which hot water is discharged without continuously supplementing cold water of 10 ℃ is adopted, only the hot water of 30 ℃ of 45L is continuously supplied. Compared to the "daily (no water supplement)" mode, 80L of hot water at 30 ℃ is provided less.
