Description
Technical Field
The invention belongs to the field of temperature control, and particularly relates to a secondary regulating device for shower water temperature.
Background
The current method for using water for showering of the popular bathhouse is as follows: the cold water is heated to a high temperature of 50-70 ℃ by a boiler or other heating methods and stored in a hot water tank. The water temperature of the actual person in the shower is about 40 ℃. The general shower water temperature adjusting method comprises the following steps: the water tank is heated and cooled by an operator according to the temperature of the water in the shower water tank. When the water temperature of the shower is high, cold water is fed into the shower water tank, and when the water temperature of the shower is low, the water is heated. The primary basis for heating the water or cold water is the temperature displayed by the temperature display of the shower water tank. The other method is to use a temperature control instrument to automatically add cold water and heat into the shower water tank. The disadvantage of both of these methods is that there is a large lag in temperature display due to the large volume of the shower water tank. After adding hot or cold water, it takes a while to actually display the temperature after the actual mixing. Due to the uneven cold and hot water, the phenomenon of supercooling or overheating occurs in the bathing process. If the water temperature is proper, the normal water temperature can be recovered after partial shower water needs to be discharged. Resulting in a large amount of wasted hot water, which increases the operating cost. Meanwhile, because the shower water tank needs to be continuously filled with water by manpower, great labor intensity is brought to an operator.

A plurality of baffles are arranged in the first-stage water mixing tank, and adjacent baffles are arranged in a staggered mode, so that water flow in the first-stage water mixing tank flows out in a W shape.
The beneficial effects of the invention are:
1. the invention has the advantages that cold water enters the primary water mixing tank from the electromagnetic valve group, and the control box controls the opening number of the electromagnetic valves in the electromagnetic valve group, thereby controlling the water inflow of the cold water. The water inlet quantity of the cold water is gradually increased or decreased, so that the water temperature is stably changed. In addition, cold water and hot water simultaneously enter the first-stage water mixing tank with small volume, so that the hysteresis of temperature change is effectively reduced. Thereby increasing the speed of the reaction of the control box.
2. The water from the first-stage water mixing tank enters the second-stage water mixing tank. The cold water and the hot water are more fully mixed and stirred to reach the proper shower water temperature for shower.
3. The invention can greatly reduce the labor intensity of workers and reduce the expenditure of manpower. The temperature of the water discharged by the shower head is stable and accurate, and the comfort degree of bathers during bathing is increased. Meanwhile, because the shower water outlet is stable and accurate, the overheated or supercooled water does not need to be discharged, a large amount of energy consumption is saved, and the cost is reduced.

The present invention will be further described with reference to the following specific embodiments. Certain well-known elements of the drawings have been omitted or scaled in order not to obscure the embodiments of the invention.
Case one
As shown in figure 1, the hot water in the hot water tank 1 is provided by a boiler or other heating methods, the temperature of the water is 50-70 ℃, the electromagnetic valve group 5 is internally composed of a plurality of groups of electromagnetic valves, the primary water mixing tank 2 is a small-volume closed water tank, and the volume of the primary water mixing tank is less than 0.075m 3 . As shown in fig. 3, a hot water inlet 203, a cold water inlet 201, a mixed water outlet 202, and a mixed water temperature sensor mounting hole 204 are left outside the primary water mixing tank 2. The hot water inlet 203 and the cold water inlet 201 of the primary water mixing tank 2 are located on the same side of the tank, with the cold water inlet 201 being located above the primary water mixing tank 2. And a mixed water outlet 202 is positioned at the other side, a mixed water temperature sensor mounting hole 204 is positioned at the intersection of the hot water and the cold water, and a mixed water temperature sensor 7 is mounted in the hole for measuring the temperature of the mixed hot water and cold water entering the primary water mixing tank 2. The first-stage water mixing tank 2 is internally provided with a plurality of baffles, as shown in fig. 4, the baffles can enhance the bearing capacity of the water tank and can ensure that cold water and hot water are stirred and mixed in the water tank.
The control box can set the temperature of the shower water, and the solenoid valve set 5 is also controlled by the controller 4. The two check valves 9 are used for preventing water backflow caused by different pressures of cold water and hot water.
Hot water directly flows into the primary water mixing tank 2 from the hot water tank 1, and cold water entering the primary water mixing tank 2 is controlled by the electromagnetic valve group 5. The controller 4 controls the number of open solenoid valves in the solenoid valve group 5 according to the hot water temperature, the shower water temperature, the mixed water temperature and the set temperature, thereby controlling the flow rate of cold water entering the primary mixed water tank 2. The cold water and the hot water are preliminarily mixed and stirred in the first-stage water mixing tank 2 of small volume. The temperature is fast in response speed due to the small volume, and the rapid adjustment is easy to realize. The water after the initial mixing is discharged from the first-stage water mixing tank 2 and enters the second-stage water mixing tank 3 with large volume for fully mixing. The secondary water mixing tank has larger volume, and the influence of a small amount of injected new water on the water temperature is smaller, thereby being beneficial to the stability of the water temperature of the shower. The water from the second-stage water mixing tank 3 is the water with the set temperature. If the set temperature is about 40 ℃, the shower head can directly enter the shower head 10 for people to bath.
Case two as shown in fig. 2, the difference from case one is that a pressurizing pump 11 is added at the source of the cold water. In the system, hot water directly enters the primary water mixing tank 2, and cold water can enter the primary water mixing tank 2 only through the control of the electromagnetic valve group 5. It is required that the pressure of the cold water is higher than that of the hot water so that the cold water can enter the primary water mixing tank 2. In a general installation environment, the pressure of tap water is higher than that of hot water, so that the pressure pump 11 is not required to be installed. In some situations the cold water may come from a cold water tank, and a booster pump 11 is required.
