Description

An automatic sensory spray bathtub with simulated fountain effect

technical field

The invention relates to an intelligent bathtub, in particular to an automatic induction type water spray bathtub simulating the effect of a fountain.

Background technique

With the continuous innovation and development of science and technology, new smart things and new products are emerging one after another, from the most common sensor faucets and smart toilets in the early stage of bathroom products to the hot selling automatic flushing massage bathtubs and bathroom cabinets And so on, have brought more comfortable bathroom new enjoyment for consumers. The intelligent technologies currently being applied in bathroom products mainly include:

Induction technology, such as the induction faucet launched by many international famous brands, is very popular, and infrared induction control can be realized without human contact (such as pressing, pressing, lifting, pulling, etc.), automatic water, hand sanitizer, hot air, etc. But this technology has not been applied to the bathtub at present.

Constant temperature technology, such as it is extremely sensitive to temperature, adjusts the mixing ratio of hot water and cold water through the mutual balance with general bias springs, keeps the water temperature constant, and will not cause sudden changes in water temperature due to changes in water pressure and water temperature Hot and cold. When the cold water is suddenly interrupted, the hot water can be automatically turned off within a few seconds, so that scalding accidents will no longer occur. There is a thermostat knob to adjust the temperature. Consumers can keep the temperature of the bath at different points according to their personal preferences, physical conditions, and different seasons, and choose the constant temperature bath they need in the range of 26-52°C. It really realizes the humanization of bathing.

At present, the main disadvantage of the traditional bath is that it consumes a lot of water and is inconvenient to use, and the shower cannot achieve the experience effect of the bath, and at the same time, the water loss is not small.

On the basis of constant temperature technology, bathtub products combined with induction technology will bring users a brand-new bathing experience. The control of the shower head, non-contact, makes bathing more comfortable, relaxed, hygienic and healthy.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1-4, the present invention is an automatic induction-type water spray bathtub simulating the effect of a fountain, including a bathtub cylinder 1, and the sides of the bathtub cylinder 1 are staggered with water spouts 6 and drainage seams 7, and the center of the bottom surface It has a ring-shaped water outlet 8, a support platform 2 is placed at the lower part of the center of the bottom surface, and a water pipe 4 is installed under one end of the bathtub cylinder body 1; in addition, the automatic induction spray bathtub also includes a control system and a remote control terminal 14; the control The system includes a power supply module 11, two infrared sensing modules 9, a temperature sensing module 13, a single-chip microcomputer 12, and a movable switch 10; the single-chip microcomputer 12 is placed inside the bathtub body 1; In the groove; the movable switch 10 is suspended above the bottom surface of the bathtub cylinder body 1, and the empty groove at the center of the lower surface of the movable switch 10 has a built-in touch plate 3, and the power module 11 and the touch plate 3 are in contact with each other, and the solenoid valve 5, Infrared sensing module 9, temperature sensing module 13 and single-chip microcomputer 12 provide power; Induction module 13 and infrared induction module 9 are all linked to each other with single-chip microcomputer 12; Described water pipe 4 pipelines are equipped with a water solenoid valve 5, and the control wire of described water solenoid valve 5 is connected single-chip microcomputer 12, and remote control terminal 14 communicates with bluetooth network. The Bluetooth module 15 of the single-chip microcomputer 12 is connected.

The user sets the water temperature on the remote control terminal 14, and transmits it to the single-chip microcomputer 12 through Bluetooth; when the person stands in the bathtub cylinder body 1, the movable switch 10 is pressed down by gravity, and the power module 11 and the touch panel 3 are in contact with each other to conduct water. Power supply with electromagnetic valve 5, infrared sensing module 9, temperature sensing module 13 and single-chip microcomputer 12; Infrared sensing module 9 senses human body height, and temperature sensing module 13 senses water temperature; After the temperature is fixed, the single-chip microcomputer 12 controls the water use solenoid valve 5 to adjust the water spray pressure of the water pipe 4 to make the water spray height reach the induction height. The specific formula is as follows:

$\mathrm{<span\; class="notranslate">\; f</span>}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; 2</span>}\sqrt{\mathrm{<span\; class="notranslate">\; 3</span>}}}{\mathrm{<span\; class="notranslate">\; 3</span>}}\mathrm{<span\; class="notranslate">\; mg</span>}<span\; class="notranslate">\; +</span>\mathrm{<span\; class="notranslate">\; a\&rho;g</span>}<span\; class="notranslate">\; -</span>\frac{\sqrt{\mathrm{<span\; class="notranslate">\; 3</span>}}}{\mathrm{<span\; class="notranslate">\; 3</span>}}\mathrm{<span\; class="notranslate">\; C</span>}$

The above formula is obtained according to the state of balanced movement of the water flow under the gravity, water spray pressure and water nozzle pressure when it reaches the critical state of the water nozzle. The pressure formula of the fluid at the water nozzle is as follows:

$\mathrm{<span\; class="notranslate">\; P</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; C</span>}<span\; class="notranslate">\; -</span>\sqrt{\mathrm{<span\; class="notranslate">\; 3</span>}}\mathrm{<span\; class="notranslate">\; a\&rho;g</span>}$

The above formula is derived from the Bernoulli equation of fluid mechanical energy conservation And kinetic energy, potential energy energy conservation principle The reasoning results are shown in Figure 5, where F is the water spray pressure to be set, p is the pressure at the starting point O of the fluid, v is the flow velocity at the starting point O of the fluid, m is the mass of the fluid at the starting point O, and ρ is Fluid density, g is the acceleration of gravity, C is a constant, a is the distance from the infrared sensor module 9 to the highest point O' of the person, and a' is the fluid movement distance to be set. Since the radius L of the bathtub is not greater than 50cm, a 'Approximate to a, h is the vertical height of the sensing point (h=asinθ), θ is the installation angle of the water pipe nozzle, that is, the spray angle, which is set to 60°.

During use, the water spray height changes with the height of the human body. When a person is lying down, the water spray height is the lowest, the required water spray pressure is the minimum, and the pressure on the water spray port is the highest; when the water level in the bathtub is too high, the water It flows out from the drainage seam 7; after the bath is finished and the person leaves the bathtub, when the movable switch 10 has no gravity, it automatically bounces upwards, the power supply is disconnected, the water outlet 8 is opened, and the bathing water flows out.
