Abstract
The utility model relates to a cold/hot water automatic regulation water tap which is composed of a control circuit and a temperature regulating valve, wherein, the temperature regulating valve is composed of a water proportioning bar in a hollow box body, a sliding groove used for the bar to slide, a cold and a hot water inlet pipe mouths on the box body, a water outlet below the box body and a reversible electric machine outside the box body, wherein, a cold and a hot water inlets are opened near both ends of the water proportioning bar, and spacing in each water inlet is unequal to spacing in each water pipe mouth. The shaft end of the reversible electric machine is provided with a gear which is meshed with a rack bar on the water proportioning bar, and under the control of the control circuit, the reversible electric machine drives the water proportioning bar to slide to alter the proportion of the cold and hot water through the water inlet on the bar for regulating and controlling water temperature in the box body and keeping constant according to preset temperature.
Description
The utility model belongs to daily life field, relates to a kind of bath water temperature control device.
Cold water pipe and hot-water line are generally all established in the bathroom,, are made hot and cold water mix appropriateness and carry out bathing by the water valve regulating water-quantity on each water pipe by the bather.Because the heating boiler water-exit temperature changes often, tap water hydraulic also often be among the fluctuation and in the bathroom bather number indefinite, cause the water temperature of modulated control appropriateness very unstable, the bather gets and often regulates and control two water valves, has not only bothered water temperature but also easy-regulating appropriateness not.Hot water is scalded the people, and water valve grade easy to failure happens occasionally.
The utility model purpose is to propose a kind of cold and hot automatic temperature-control water tap, and it can be according to bather's setting, automatically hot and cold water is mixed into to set temperature and keep constant, and is very easy to use.
The utility model purpose is achieved in that hot and cold water automatic temperature-control water tap is made up of control circuit and heat control valve two-part.Heat control valve is made up of hot water or cold water's tube inlet, mixing water water outlet, the outer reversible electric machine of casing on the casing of hollow, the water distribution rod, chute, casing in the casing.The reversible electric machine shaft extension is gone in the casing, and axle head is with gear, and the water distribution rod lies in a horizontal plane in the chute, and there is tooth bar at rod middle part, and the gear matched of itself and reversible electric machine axle head can make the water distribution rod horizontally slip in chute.The nearly two ends of water distribution rod have hot water or cold water's water intake, and spacing does not wait with the interior spacing of hot water or cold water's tube inlet in these two mouthfuls.Control circuit is made up of measurement bridge circuit, signal amplification comparison circuit, current amplification circuit.When by after setting the potentiometer setting temperature by measure bridge circuit with the signal of perception through amplify comparison circuit, current amplification circuit control reversible electric machine just changes or reverse, transmission water distribution rod horizontally slips, thereby make hot water or cold water water inlet and hot water or cold water's mouth of pipe on it the different bore that staggers respectively, make the hot water or cold water be mixed to the temperature of setting and make water temperature constant.
Owing to adopt such scheme, make newly that the water temperature in the casing is not caught a cold, the influence of water temperature, hydraulic pressure in the hot-water line, can and keep constant automatically by bather's requirement regulation and control.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a hot and cold water automatic temperature-control water tap heat control valve generalized section.
Fig. 2 is a hot and cold water automatic temperature-control water tap heat control valve partial enlarged drawing.
Fig. 3 is hot and cold water automatic temperature-control water tap control circuit figure.
Fig. 4 is a hot and cold water automatic temperature-control water tap control circuit partial enlarged drawing.
Below in conjunction with accompanying drawing in detail embodiment is described in detail.
9 are the heat control valve casing among Fig. 1, hollow, water-fast by glass fibre reinforced plastics, plastics etc., insulate, have the material of certain intensity to make.Both sides have 2 holes on the casing 9, insert hot-water line 1, cold water pipe 11 respectively.Substantially horizontal has 2 chutes 2 in the two side, casing 9 interior top.4 are the water distribution rod, and Manufacturing material is with casing 9, and its two ends load is placed in the chute 2, can freely horizontally slip in chute.Place, water distribution rod 4 nearly two ends has hot water inlet 3 and cooling water inlet 12, spacing is in this 2 import: when hot water inlet 3 aligns with the port of hot-water line 1, cooling water inlet 12 ports proper and cold water pipe 11 stagger fully, block cold water fully via in this mouthful inflow box cavity 5.The 6th, the water outlet of casing below.The 7th, reversible electric machine, the 8th, motor shaft, it passes casing 9 rear and lower end and aligns with water distribution rod 4, passes the casing place at motor shaft 8 water seal is housed.10 are arranged on the temperature-sensitives resistance R4 of below in the casing, and it links to each other with casing 9 control circuit outward.Motor shaft shown in Figure 28 lower ends are with gear 14, and the middle part of water distribution rod 4 is a tooth bar 13, and the two engagement can make water distribution rod 4 move left and right.F box indicating power supply amplification circuit among Fig. 3, its enlarged view is seen Fig. 4.Form the measurement bridge circuit by 2 1.8K metal film resister R1, R2, setting potentiometer R3 and temperature sensitive resister R4.After R3 sets, if R4＞R3, when promptly mixing the water water temperature greater than the temperature set, C point voltage then) D point voltage is by R5, the R6 of 5.1K, the R7 of 6.8K, the amplification comparison circuit output negative voltage that the R8 metal film resister of 24K and IC741 form reverses through power supply amplification circuit control reversible electric machine 7; Otherwise reversible electric machine 7 is just changeing.When R4=R3, then IC741 output approaches zero, and reversible electric machine 7 stalls this moment promptly stop to mix water.Because reversible electric machine 7 rotates forward or backwards, drive water distribution rod 4 and slide to the left or to the right, thereby controlled the ratio that enters hot water and cold water in the box cavity 5, reached by the mixed water of setting temperature with kept the constant of water temperature.C1 is the capacitor of 0.47 μ f, and is in parallel with R8, plays delay circuit, protection water distribution rod 4 two ends and chute 2 two ends are not rigid answers back to.
During bathing, will set potentiometer R3 and be threaded to temperature required corresponding position and get final product.
The The whole control circuit board is with resin-sealed, and is isolated with water.The utility model can be used for the place that other hot and cold water mixes.
