Description

The present invention relates to a device for controlling

  and remotely programming the flow rate and temperature of a liquid flowing in a distribution circuit.

  It applies in particular to the regulation of the flow and temperature of a water flow used for domestic purposes, especially for taking showers or baths.

  It is known that in order to control the temperature and the flow rate of a liquid in a distribution circuit, a mixer fed with cold liquid and hot liquid is usually used by two supply circuits each comprising a solenoid valve for controlling the flow rate. controlled by a control circuit for adjusting the flow rate of cold liquid and hot liquid arriving in the mixer according to a temperature and a flow rate.

  It turns out that this solution, which is commonly used in industrial distribution circuits, is not suitable for domestic use because of its complexity (flow control, flow sensors, temperature sensors), their cost and problems with their installation.

  Moreover, at present, in most domestic applications, instead of using separate cold water / hot water faucets to deliver hot water to the desired temperature, taps are more and more commonly used. much easier to install and more ergonomic. Indeed, the adjustment of the water temperature is generally obtained by a rotation of the head of the mixers while the adjustment of the flow (at the temperature corresponding to the angular position of the head) is obtained by a tilting a lever attached to the head.

  On the basis of this finding, the Applicant filed on April 19, 2004 a French patent application No. 04 04139 for a device for remotely controlling and regulating the flow and temperature of a liquid circulating in a fuel circuit. distribution and which comprises: a conventional mixer structure which makes it possible to regulate the temperature and the flow rate by respectively exerting a rotation of its head and a tilting of a lever secured to said head; A control box including at least one selector that allows the user to select the desired temperature and flow rate of the water flow; Au at least one converter that converts the value to be servocontrolled into a proportional voltage that constitutes a control signal; Au at least one return chain comprising a sensor which measures the output quantity corresponding to either the temperature or the flow rate of the water flow at the outlet of the distribution circuit and which converts it into a reaction signal corresponding to a voltage ; At least one comparator which generates an error signal corresponding to the difference between the control signal and the associated feedback signal; É at least one action chain comprising at least one preamplifier and a power unit to which the error signal is applied; É means connecting the power member to the mixer to allow it to exercise a horizontal rotation of the head if the temperature is controlled and a vertical rotation of the lever secured to said head if the flow is controlled.

  This patent application also relates to two distinct arrangements of the internal structure of a conventional mixing valve; these two arrangements consisting in covering the mixer with a cover comprising on its upper face one or two orifices through which (s) pass (s) means (s) consisting of a cable connecting the power organs or the housing of control mixer and more particularly to the mixing lever of the mixer and / or a trunnion connected to said lever. In this way, an action on the cable (s) causes the tilting of the lever and the rotation and / or the translation of the seat disk and the control disk connected to the lever and thus makes it possible to control the flow and the temperature water flow.

  The invention that is the subject of the invention application FR 04 04139 and its variant embodiments have the characteristic of being based solely on fully analog solutions, which has the drawback of reducing the scalability of the functionalities of the assembly and can cause a lack of precision in the regulation of the flow rate and the temperature of the liquid.

  The invention therefore more particularly aims to overcome these disadvantages by providing a remote control device of the flow rate and the temperature of a liquid within a distribution circuit, accurate and to define setting cycles the flow rate and temperature of said liquid.

  It proposes for this purpose a device for remotely controlling and regulating the flow and temperature of a liquid circulating in a distribution circuit, characterized in that it comprises: a conventional mixer structure comprising two disks: seat disc which is provided with a cold water through-hole, a hot-water through-hole and a mixed water-through hole; and a control disc comprising a flow channel disposed on the seat disc, said control disc being connected to a drive lever adapted to be moved, said translational movement. being communicated to the control disk relative to the seat disc, thus making it possible to more or less close the water inlet orifices and the outlet orifice for the mixed water and to control the flow of the mixed water; ^ to be rotated, this rotational movement being communicated to the control disk thus controlling the temperature of the flow of mixed water; Au at least one sensor connected to a control box that measures the temperature and / or the flow rate of the water at the outlet of the distribution circuit; A control box enabling the user to select the desired water flow temperature T and flow rate D, this control box comprising: a selector allowing the user to select the temperature T and the flow rate D desired flow of water consisting of a joystick with two degrees of freedom, in two orthogonal directions, the angular difference of which is strictly proportional to the relative position of said control disk relative to said seat disk; at least one display means for displaying the temperature and / or the flow rate of the water at the outlet of the distribution circuit as measured by said sensor; At least one means connecting the control box to the mixing valve; A module covering the body of the mixing valve and comprising: a first servomechanism capable of ensuring rotational movement and thus able to control the rotation of said control disc thus making it possible to control the temperature of the outlet water flow; and oa second servomechanism capable of ensuring a translational movement connected at one of its ends to the first servomechanism and at its other end to said drive lever and thus able to control the translation of said control disk thus making it possible to control the flow of the outlet water flow; An electronic unit connected to or incorporated in the control box and for controlling said servomechanisms included in the body of the mixer; É a memory zone that can be included in said electronic unit.

  Thus, a user can choose, using the selector, the desired temperature and / or flow rate of the water flow at the outlet of the distribution circuit. Depending on this temperature and this flow rate, said electronic unit controls the servomechanisms through the means (s) connecting the control unit to the mixer rotation and / or translation of said control disk thus modulating the temperature and the flow rate of the water at the outlet of the distribution circuit, the user being able to modify the selected value of the temperature and the flow rate, taking into account the temperature and the flow rate evaluated by the sensor (s) (s) and which are displayed on the display means incorporated in the control box.
