Description

 Solar water heater water measurement, water temperature measurement, hot water switch device

 The invention relates to the technical field of solar water heaters, and belongs to a solar water heater measuring water quantity, measuring water temperature and hot water switching device.

Background technique

 At present, the known solar water heater is composed of a heat collecting vacuum tube, a heat storage water tank, a bracket, a water pipe, an overflow pipe and a faucet. When using the faucet, the first thing that comes out is cool water (or cooler water). These cool waters fill the entire pipe between the faucet and the water tank. When these cool waters are finished, the hot water flows out. Users often dump these cool waters and then pick up hot water. This not only wastes water in the water tank, but also wastes time and increases the number of times the faucet is turned on and off. Especially for users whose water dragon head is far from the water storage tank, such as: users who live in low-rise buildings in high-rise buildings, every time they need to pour off more water in the half-basin. It is inconvenient for users who frequently use hot water, such as restaurants, laundries, and barber shops, and who are mostly at the bottom. Because water is always stored in the water pipe, it is easy to freeze the pipe when the temperature is low. Although it is now heated by electric heating, it not only consumes electricity, but it is easy to freeze if there is a power outage. And how much water is in the water tank? How high is the temperature? The user does not know. The amount of water measured by the electric sensor and the temperature of the water are measured, and the sensitivity is lowered due to the deposition of scale, which requires frequent maintenance. Often the faucet does not flow, only to know that the water tank is waterless. The water is hot, and I know that the temperature of the solar energy is high. Solar vacuum tubes are often bursting due to the addition of cold water at high temperatures.

Summary of the invention

 The object of the present invention is to provide a solar water heater measuring water quantity, measuring water temperature, and a hot water switching device, which can enable the user to know how much water and water temperature in the solar water storage tank is high, without frequent maintenance and a faucet flows out and The water in the water tank is the same temperature.

 The technical solution of the invention is: an integrated water temperature measuring instrument, a water measuring meter and a water control valve are arranged in the solar water storage tank, and a gas nozzle and a water pipe peripheral are arranged in the water tank outside the water storage tank. There are two cables and protective tubes. In the user's home, there are water temperature meters, water meters, alarms, and hot water taps.

 The water measuring capacity, the water measuring temperature and the hot water switching device of the solar water heater are characterized in that: it comprises a water control valve, a water meter, a water temperature meter, and a hot water tap;

 The water control raft is a sealed cylinder, and a water measuring meter and a water measuring temperature meter are connected at the top of the water control valve, and a water inlet is arranged on the side wall of the water control valve, and the bottom of the water control valve is arranged at the bottom of the water control valve. a water pipe joint is provided, and a check valve seat connected to the inner wall is arranged in the water control valve, a check valve is arranged on the check valve seat, and a top valve hand is arranged on the lower part of the check valve seat;

 The water meter is provided with a lifting pendant shaped water amount pointer;

 The temperatureometer is provided with a lifting pendant-shaped temperature pointer;

The hot water tap is provided with a fixed valve piece and a movable valve piece, and the movable valve piece is disposed on the fixed valve piece a spindle is disposed on the center of the fixed valve piece and the movable valve piece, a sleeve is sleeved on the main shaft, and a snap button is connected to the upper end of the main shaft;

 The measuring water meter has a water measuring cable, and the measuring cable has a conduit, and the measuring cable is connected from the bottom of the water control valve to the pendant-shaped water pointer;

 The water temperature measuring device is provided with a water measuring temperature cable, and the measuring water temperature cable has a conduit, and the water temperature cable is connected from the bottom of the water control valve to the pendant water temperature pointer;

 The bottom of the water control valve is provided with a hot water switch cable, and the upper end of the hot water switch cable is connected with the rear end of the top valve hand, and the lower end of the hot water switch cable passes through the water pipe and the hot water tap The moving valve piece is connected.

 The basic working principle of the invention is: when the water in the water tank increases or decreases, the floating tank on the water measuring meter moves up and down, and the floating floating tube rotates up and down. The water measuring amount in the water measuring meter is decreased or increased, so that the water quantity indicator drives the water quantity indicator on the water meter to drop or rise, reflecting the amount of water, when the water quantity pointer rises to the user-set water quantity touch When the water temperature rises or falls, the sac in the water temperature meter expands or contracts, so that the slider at the upper end of the cable in the water temperature meter rises or slides down, thereby pulling the water temperature to pull The water temperature indicator on the water meter rises or falls, reflecting the approximate temperature of the water. The alarm is triggered when the water temperature indicator rises to the temperature contact set by the user. The water measuring cable and the conduit of the water measuring cable jacket make the cable lift flexible. When the user uses hot water, turn the button on the hot water tap to the right to the "open" position, and the circular moving valve in the hot water nozzle rotates more than 90 degrees, thus pulling the pull in the hot water tap. The cable pulls down the top valve hand in the water tank control valve. Due to the action of the mast, the top valve handle acts as a check valve in the water control valve, and the hot water in the water storage tank flows out. Since the water pipe between the water storage tank and the outlet is empty, the hot water of the same temperature as that in the water storage tank flows out. When the user does not use water, turn the button back to the "off" position, the moving valve in the hot water tap is reversed, the cable is loose, and the check valve in the water tank is automatically closed under the pressure of self weight and water. The water in the water tank cannot flow out. Because the water in the water pipe is not flowing, a negative pressure is formed in the water pipe to cause poor water discharge or water storage. So set the drain nozzle. Under the suction generated by the self-weight of the water in the water pipe, the water discharge nozzle opens and puts in the air, so that the water in the water pipe is completely drained. It is especially emphasized that the button of the hot water nozzle is in the "off" position, and only the check valve in the water tank is closed, the outlet nozzle is still in an open state, and the water in the water pipe can be completely drained. When injecting cold water into the water storage tank, the button must be turned 90 degrees to the left to the "stop" position, so that the moving valve piece blocks the water outlet of the fixed valve piece. After the water injection is completed, the button must be returned to the "off" position, and the cool water in the water pipe should be drained to facilitate the next hot water use. This also avoids the danger of freezing the pipe when the temperature of the water in the pipe is lowered and the flaw of the frozen pipe. At the same time, turning the button to the "stop" position can be used as an emergency stop for hot water when the hot water flows out excessively.

The working characteristics of the present invention are: When the water temperature and the amount of water change, the user can intuitively know how high the temperature of the water is and how much water is in the water storage tank, so as to timely inject cold water and use hot water reasonably; When water is used, the water that flows out of the faucet is the same as the water temperature in the water tank. It avoids the bad situation of using hot water after pouring the cold water first, which can save water.

 The user should pay attention to: When the hot water is not full, the valve should be closed in advance. If the container is full of water and still not flowing, then you can turn the button to the "stop" position and stop immediately. Only water is still in the pipeline at this time. If the water is used for a long time, the water will cool into cold water, or the temperature will be too low to freeze the pipeline. Each time the water tank is filled with water, turn the button to the "off" position and drain the water from the pipe. So that you can use hot water next time.

 The invention has the advantages of being intuitive, convenient, and water-saving, and can be widely used with all solar water heaters. The user can intuitively understand the amount of water in the solar water heater storage tank on the roof and the top of the high building, how high the water temperature is, and when the switch is turned on, the hot water that is equivalent to the water temperature in the solar water heater storage tank is discharged. . The bottom user can pick up a cup of hot water from the solar water heater on the roof. Overcoming the previous users did not know how much water in the solar water storage tank, how high the water temperature is, when the water is used to drain the cold water in the clean pipeline before the hot water flows out, the electric sensor measures the water volume, measures the water temperature, because the scale deposits, the sensitivity decreases. The drawbacks of frequent maintenance. Only one main pipe is used to pass water on the equipment, and the overflow pipe is removed.

 The device can be independently decomposed into three sets. Namely: water measuring device, water measuring device, water control valve, hot water switch device. Separate use of "water control valve - hot water switch device" plus an interface can be used for the renewal of the old switch of the solar water heater before the use of the present invention; "water control valve - hot water switch device" can also be used as other liquid storage tank The remote control switch can reduce the immersion, corrosion and dripping of the liquid to the pipeline, which can improve the safety factor and service life of the pipeline.

The main shaft 906 is provided with a boring head 91 1 at the top end, a square shaft portion 912 at a lower portion of the main shaft 905, a positioning notch 904 at the upper end of the sleeve 905, and a positioning card 902 at a corresponding position of the snippet 901. A pupil 913 corresponding to the hoe is provided in the head of the button 901. The cable 3, 4, 801 is provided with a curved card tube 803 at the turning corners of the ducts 302, 402 and the down pipe 8. Used to reduce the frictional resistance when the cable, 801 passes through angled walls, tees, and elbows.

 The water measuring cable 4, the water measuring cable 3, the hot water switch cable 801 intermediate joints are respectively provided with cable junction pieces 401, 301, 802 for the connection between the cables;

 Next to the lower header 508, there are a water measuring gauge 6 and outlet nozzles 12 and 13 of the cables 3, 4 of the water measuring gauge 7, which are respectively connected to the cable conduits 302, 402, directly connected to the water meter 1 and the water temperature. Table 2; when the conductive water amount pointer 101, the temperature pointer 201 rises to the top contact with the amount of water set by the user according to his own needs, the water level positioning conductive contacts 102, 202, the buzzer 10 is turned on;

 When the button 901 on the hot water faucet 9 is rotated to the "on" position (see FIG. 12, turning right), the cable 801 is pulled to rotate the length of the valve plate 907 by a length of 1/4, thereby downward. Pulling the top valve hand 507 (see Fig. 2), jacking up the check valve 503, causing the hot water in the water storage tank to flow downward, passing through the lower water pipe 8 to the water outlet faucet 9, flowing out from the water outlet 915 of the fixed valve piece 909; When the hot water fills the water container quickly, turn the button 901 to the "off" position (see Figure 11 for a close). Since the cable 801 is reversed, (see Figure 2) the top valve hand 507 loses tension. The wide door 503 is closed under the combined action of the self-weight and the water pressure, and the hot water in the water storage tank cannot flow out; however, at this time, there is still hot water in the lower water pipe 8, and the negative pressure is formed due to the closing of the check valve 503, and then the pressure is released. The suction force formed by the water nozzle 509 due to the pressure of the outside atmosphere and the gravity of the water in the down pipe causes the beads 515 (see Fig. 20) in the drain nozzle 509 to retreat, thereby opening the drain nozzle 509 to make the downpipe The water flow in 8 is net; if the water receiving container is full and the hot water is still not flowing, The button 901 turns left to the "stop" position, (see FIG. 13 left turn and stop). The moving wide piece 907 completely blocks the water outlet hole 915 on the lower fixed valve piece 909, and stops immediately; it is noted that: When injecting cold water into the solar water storage tank, the snap button 901 must also be turned to the "stop" position to close the water outlet hole 915 in the fixed valve piece 909 to prevent water from flowing out of the hot water faucet 9; when the water storage tank is filled with water When the button 901 is turned to the "off" position, the cool water in the down pipe 8 is drained, so that the next time the hot water is used and the temperature is lowered to freeze the water pipe 8; it should be noted that when the button 901 is turned When the position of "ON" is turned (see Figure 12, turn right), the cable 801 is pulled back by the downward force of the water. With a loose hand, the button 901 will automatically revert to the "off" position. If you want to release the water and release the water (see Figure 3), the button 901 can be pressed down in the "on" position, so that the card 902 on the button 901 is caught in the slot 904 of the sleeve 905. When hot water is not used, the button 901 must be lifted up and then turned to the "off" position.

Referring to Figures 14, 15, and 16: the water measuring gauge 6 is composed of a fixed column 601, a rotating floating tube 602, a bellows 605, a floating box 607, and a tube head 606; one end of the cable 4 is inserted from the tube head 606, and is "into" The "shape" passes over the small ring 604, is attached to the uppermost ring, and the other end passes through the tube mouth 606 and is connected via a conduit 402 to the water hand 101 on the water meter 1. When the water tank is filled with water, it floats The tube 602 and the pontoon 607 are floated due to the buoyancy of the water, so that the opening angle between the rotating floating tube 602 and the fixed column 601 becomes smaller, and the small ring 604 is close to each other, thereby compressing the bellows 605, causing the water measuring amount of the cable 4 due to The gravity of the water amount pointer 101 falls downward. When the water is reduced, the float 607 is lowered, and the floating float 602 is laid down downward so that the small loops 604 are moved away from each other, thereby pulling up the cable 4, causing the water amount pointer 101 to rise. This will show an approximate amount of water on the water meter 1. The pontoon 607 is a sealed hollow box. The rotating float 602 is a sealed hollow tubular body. The pontoon collar 608, which can be rotated up and down, causes the pontoon 607 to float up and down within a defined range of the fixed upright 601 and the rotating float 602. The maintenance ring 609 is when the device is installed and repaired, the water tank is free of water, and the angles of the rotating floating tube 602 and the fixed column 601 are too large, so that when the water control valve 5 cannot be unscrewed, the air outlet is used from the outside of the water storage tank. The long hook lifts the floating box 607 so that the fixed column 601 and the rotating floating tube 602 are close together to facilitate the rotation of the water control valve 5. The fine water measuring amount of the cable 4 falls downward due to the gravity of the water amount pointer 101. Or when the water is small, the fine water measuring cable 4 is retracted, and the water amount pointer 101 is pulled to move, and the water amount is displayed on the water meter 1. When the water amount pointer 101 reaches the high end, the contact 102 is touched (the amount of water indicated by the contact 102 is set by the user), and the buzzer 10 alarms.

There is a vertical slot 702 and a slider 705. The slider 705 is connected to the thin water measuring cable 3, and the cable 3 passes through the vertical slot 702 from the bottom end, and passes through the cable guide 302 and the temperature pointer 201 in the water temperature meter 2. connection. When the temperature of the water in the storage tank rises, the volume of the liquid in the sac 703 expands, causing the sac tube 704 to rise straight up, jacking up the slider 705, thereby pulling the cable 3 in the vertical slot 702, The temperature pointer 201 that drives the lower end of the cable 3 moves upward, indicating the temperature on the water temperature gauge 2. When the temperature pointer 201 reaches the high end, the contact 202 is touched (the water temperature indicated by the contact point 202 is set by the user), and the buzzer 10 alarms.

 See Figure 3: The moving valve piece 907 is a moving piece. The fixed valve piece 909 is a fixed piece. The movable valve piece 907 and the fixed valve piece 909 are tightly laminated, and the movable valve piece 907 can freely rotate between the posts 910 around the main shaft 906. When the protruding head 908 hits the right post 910, the pulling in the cable eye 917 The cable 801 is pulled more than 90 degrees arc length. Since the water outlet hole 918 is larger than the fan surface of the water outlet hole 915 by 90 degrees, the water can still flow out from the water outlet hole 918; the upright curved block 916 ensures that the cable 801 is pulled to a certain extent. The length of the arc.

 When the nose 908 hits the left post 910, the water outlet 918 seals the water outlet 915, the water cannot flow out, and the upright curved flap 916 blocks the slack cable 801 from being flushed into the water outlets 918 and 915.

Referring to Fig. 23, Fig. 24, Fig. 25, the "water" pipe (8) is connected with a "person" word tee 804, and an arrow-shaped partition 806 is disposed in the middle of the "person" word tee 804. An intermediate ring 805 is disposed on the plate, and a water dividing card 821 is disposed under the partition plate. The water dividing card 821 is a left and right valve 808 arranged in a V shape by a rotating shaft 820 and fixedly connected on both sides of the rotating shaft. 816, on the left, The lower part of the right valve is provided with left and right water outlets 810, 817, and the left and right upper small rings 809, 815 are connected to the left and right side walls 808, 816, and the left and right water outlets 810, 817 are under the side walls. The left and right lower small rings 811 and 818 are connected; the left cable 807 is passed through the middle ring 805, the upper left small ring 809, and the lower left small ring 811, and the lower end of the left cable 807 is connected to the left cable piece 812. The upper end of the left cable 807 is connected to the upper cable 813; the middle ring 805, the upper right small ring 815, and the lower right small ring 818 pass through the right cable 814, and the lower end of the right cable 814 is connected to the right cable 819. The upper end of the right cable 814 is connected to the upper cable piece 813.

 When the user needs to use hot water in multiple places in the room, it is necessary to use multiple sets of "person" word tee 804 or "d" word tee 831 to connect the hot water tap 9 in multiple places. For example: kitchen, bathroom, bathroom, etc. The invention installs the "human" word tee 804 in the middle of the water pipe, and its structure is as shown in Fig. 23: when the user turns the button of the hot water tap connected to the right side, the right cable 814 is pulled, due to the middle ring 805, the upper right ring 815, the lower right small ring 818 is restricted, so that the right cable 814 is changed from bending to rigidity, so that the water dividing card 821 is rotated, the right valve 816 is erected, and the right water opening 817 is opened; meanwhile, the left valve 808 pieces are fallen down and blocked. At left port 810, hot water can only flow from the right spout 817. On the contrary, hot water flows through the left water outlet. When the user injects cold water into the solar water heater, the reverse force of the water naturally causes the water distribution card 821 to open the water-passing water outlet to cover the waterless water outlet. The "man" word tee 804 is made of a flat ribbon to reduce the gap between the water dividing card and the water inlet, and the cable 813 is connected to the 812 and 819 by the cable 813. When the diameter of the upper valve piece 907 is lengthened, the arc length of the upper valve piece 907 is lengthened, and the hot water tap 9 can be installed at a plurality of places by using a plurality of sets of "person" word tees 804. The invention installs the "D" word tee 831 in the middle of the water pipe, and its structure is as shown in Fig. 26. Fig. 27: When the user pulls the right cable 829, the water distribution card 824 is turned to the left side due to the limitation of the small rings 826 and 827. , thereby covering the water outlet 825. The water flows out from the right end of the "Ding" word tee. Otherwise, it is deep out from the left end. Users need to be aware that when using hot water, it is not possible to turn on two or more hot water taps at the same time.

 Since the invention has the advantages of convenience, water saving, power saving, and the use of a water control valve and a hot water switch as a remote switch of the liquid storage tank, it can be widely used with all solar water heaters.
