Description

Title of the invention: Installation for chlorinating swimming pool water Technical field of the invention

[0001] The present invention relates to the technical field of installations for chlorinating swimming pool water. State of the art

[0002] Swimming pools are popular recreational facilities and the quality of their water is of paramount importance to protect the health of swimmers.

[0003] A widely used method for maintaining water quality is to add chlorine compounds, which effectively disinfect the water by eliminating harmful microorganisms.

[0004] For water chlorination, current installations rely on different technologies, in particular electrolysers.

[0005] The operation of the electrolyser consists of circulating an electric current between two platinum plates (electrolysis cell) so as to produce chlorine from the salt dissolved in the water.

[0006] This type of equipment is very widespread but does have some limitations:

[0007] - the electrolyser has a finite chlorine production capacity: in the event of a heatwave, storm or intensive use of the pool, it may happen that the chlorine produced is not enough to treat the water;

[0008] - the lifetime of the electrodes is limited (wear during production);

[0009] - the lower the water temperature, the less efficient the chlorine production and the faster the electrodes wear out.

[0010] In particular, it is customary to stop the production of chlorine by the electrolyser when the water temperature is below a minimum threshold value (for example 15°C) so as not to unnecessarily damage the electrodes.

[0011] Some chlorination installations then integrate an additional dosing pump, which is used below the minimum threshold value, instead of the production of chlorine by the electrolyser.

[0012] Such metering pumps are thus used to precisely inject chlorination chemicals into the pool water in order to maintain the appropriate chlorine levels.

[0013] However, in practice, the limit between the rapid degradation temperature, on the one hand, and the nominal operation of the electrodes of an electrolyser, on the other hand, is not limited to a minimum threshold value.

[0014] There is therefore a need for a technical solution that would make it possible to overcome the limitations of electrolysers, particularly in relation to temperature thresholds. Presentation of the invention

[0015] In order to overcome the aforementioned drawback of the state of the art, the present invention proposes an installation for chlorinating swimming pool water.

[0016] This chlorination installation comprises:

[0017] - chlorination means, for adding chlorine to said water, comprising:

[0018] — electrolyser means, for example an electrolyser for a swimming pool, and

[0019] — injector means, for example a liquid chlorine dosing pump,

[0020] - temperature sensor means, for measuring a collected temperature value temperature of the water in said swimming pool,

[0021] - means for measuring the chlorine level, for measuring a collected content of chlorine from the water of said swimming pool, and

[0022] - control means, comprising:

[0023] — a calculation module, to determine a quantity of chlorine to be supplied taking into account taking into account the said collected chlorine content and a set chlorine content, and

[0024] — a control module, for controlling said chlorination means as a function of the said quantity of chlorine to be supplied.

[0025] And, according to the invention, said control module is configured to distribute said quantity of chlorine to be supplied between said electrolyser means and said injector means, taking into account said collected temperature value and temperature thresholds of the water in said swimming pool, namely:

[0026] - an injection configuration, when said collected temperature value is in below a minimum temperature threshold, in which said injector means are controlled to supply said quantity of chlorine,

[0027] - an electrolyzer configuration, when the collected temperature value is su above a maximum temperature threshold, in which said electrolyser means are controlled to produce said quantity of chlorine, and

[0028] - a hybrid configuration, when the collected temperature value is included between said temperature thresholds, in which said electrolyser means and said injector means are controlled to each generate a share of said quantity of chlorine,

[0029] said share of the quantity of chlorine produced by said electrolyser means increasing with said collected temperature value.

[0030] Such a technical solution makes it possible to avoid a sudden switching between the electrolyser means and the injector means, at the minimum threshold temperature.

[0031] On the contrary, it ensures a progressive passage between the electrolyser means and the injector means, over a range between two threshold temperatures.

[0032] Other non-limiting and advantageous characteristics of the product / process according to the invention, taken individually or in all technically possible combinations, are the following:

[0033] - the minimum temperature threshold is 14 to 16°C and the maximum temperature threshold is 19 to 21°C;

[0034] - said control module is configured to increase continuously, or discontinuously, said first share Cal of the quantity of chlorine produced by said electrolyzing means;

[0035] - said control module is configured to continuously increase said first share of the quantity of chlorine to be supplied produced by said electrolyser means, among a continuous linear increase, a continuous logarithmic increase, a continuous exponential increase, a continuous polynomial increase;

[0036] - said control module is configured to discontinuously increase said first share of the quantity of chlorine produced by said electrolysing means, among levels, for example each degree of temperature;

[0037] - the control means comprise an additional calculation module, for complete a quantity of additional chlorine to be added, taking into account at least one additional parameter, which additional parameter is chosen for example from weather conditions which do not allow the electrolyser means to counter the development of bacteria and algae, intense use of said swimming pool, the status of the electrolyser means, in particular the electrodes, in particular at the end of their life, a salt level in the water which is below a minimum threshold;

[0038] - the control means comprise means for implementing the steps following: a step of calculating said quantity of chlorine to be supplied, taking into account said collected chlorine content and a set chlorine content, a chlorination step, taking into account said collected temperature value and said temperature thresholds, according to one of the configurations chosen from said injection configuration, said electrolyser configuration and said hybrid configuration.

[0039] The present invention also relates to a swimming pool equipped with an installation for chlorinating the water of a swimming pool, according to the invention.

[0040] The present invention also relates to a method for chlorinating swimming pool water, by implementing an installation according to the invention.

[0041] This method comprises:

[0042] - a step of calculating said quantity of chlorine to be supplied, taking into account said collected chlorine content and a set chlorine content,

[0043] - a chlorination step, taking into account said collected temperature value and of said temperature thresholds, according to one of the following configurations:

[0044] — an injection configuration, when said collected temperature value is in lower than said minimum temperature threshold, in which said injector means are controlled to generate said quantity of chlorine to be supplied,

[0045] — an electrolyzer configuration, when the collected temperature value is su above said maximum temperature threshold, in which said electrolyser means are controlled to generate said quantity of chlorine to be supplied, and

[0046] — a hybrid configuration, when the collected temperature value is included between said temperature thresholds, in which said electrolyser means and said injector means are controlled to each generate a share of said quantity of chlorine to be supplied,

[0047] the share of the quantity of chlorine to be supplied by said electrolyser means increasing with said collected temperature value.

[0048] Preferably, the process comprises a complementary chlorination step, taking into account at least one additional parameter.

[0049] This additional parameter is chosen for example from:

[0050] - weather conditions which do not allow the electrolyser means to counter the development of bacteria and algae,

[0051] - intense use of said swimming pool,

[0052] - the status of the electrolyser means, in particular the electrodes, in particular at the end of life,

[0053] - a salt level in the water which is below a minimum threshold.

[0054] Of course, the various features, variants and embodiments of the invention may be combined with each other in various combinations to the extent that they are not incompatible or mutually exclusive. Detailed description of the invention

[0055] Furthermore, various other characteristics of the invention emerge from the appended description given with reference to the drawings which illustrate non-limiting forms of embodiment of the invention and where:

[0056] [Fig-1] is a schematic view, in the form of a block diagram, of the installation of chlorination according to the invention;

[0058] [Fig.3] is a schematic view, in the form of a block diagram, of the method of chlorination according to the invention.

[0059] It should be noted that, in these figures, the structural and / or functional elements common to the different variants may have the same references.

[0060] As described in connection with [Fig. 1], the present invention thus relates to installation 1 for chlorinating the water of a swimming pool (not shown). Such an installation 1 is also called “chlorination installation 1”.

[0061] By "chlorination installation" is advantageously meant an installation designed to add chlorine compounds to the swimming pool water, in order to effectively disinfect the water by eliminating harmful microorganisms.

[0062] Generally speaking, the chlorination installation 1 according to the invention comprises:

[0063] - chlorination means 2, for adding chlorine to the swimming pool water,

[0064] - temperature sensor means 3, for measuring a collected value of tem temperature Te of the swimming pool water,

[0065] - means for measuring the chlorine level 4, for measuring a collected content of chlorine from the pool water, and

[0066] - control means 5, in particular for controlling the chlorination means 2 depending on the amount of chlorine to be supplied Ca and the collected temperature value Te. Chlorination methods

[0067] According to the present invention, the chlorination means 2 comprise two components:

[0068] - electrolyser means 21, and

[0069] - injector means 22.

[0070] The electrolyser means 21, for example an electrolyser for a swimming pool, are advantageously conventional in themselves.

[0071] Such electrolyser means 21 advantageously consist of circulating an electric current between two platinum plates (electrolysis cell) so as to produce chlorine from salt dissolved in the water.

[0072] The injector means 22, for example a liquid chlorine metering pump, are advantageously conventional in themselves.

[0073] Injector means 22 are for example connected to a chlorine tank, for distributing a dose of chlorine into the swimming pool water.

[0074] Generally speaking, the chlorination means 2 can be positioned on the swimming pool water filtration circuit. Temperature sensor means

[0075] The temperature sensor means 3 are advantageously conventional in themselves.

[0076] For example, these temperature sensor means 3 consist for example of a thermistor or a digital temperature sensor, immersed in the swimming pool water or installed to measure the temperature of the water in the water circulation pipes. Means of measuring chlorine levels

[0077] The means for measuring the chlorine level 4 are advantageously conventional in themselves.

[0078] For example, these means for measuring the chlorine level 4 consist of a redox probe or a chlorine probe. Means of ordering

[0079] Preferably, the control means 5 comprise a data processing system comprising means for implementing the method described below.

[0080] More preferably, the control means 5 advantageously comprise a microcontroller in which is stored a computer program which comprises instructions which, when said computer program is executed by said microcontroller, cause the latter to control the chlorination means 2 according to a method described below (also called “algorithm”).

[0081] Still generally, the control means 5 are advantageously in the form of an industrial programmable automaton, namely a programmable digital electronic device which sends orders to the chlorination means 2 from input data coming from sensors (in particular the temperature sensor means 3 and the chlorine level measuring means 4), from instructions and from a computer program.

[0082] More specifically, the control means 5 comprise:

[0083] - a calculation module 51, to determine a quantity of chlorine to be supplied Ca holding taking into account the collected chlorine content Ce and a set chlorine content Ct, and

[0084] - a control module 52, for controlling the chlorination means 2 according to the amount of chlorine to be supplied Ca.

[0085] In particular, the calculation module 51 determines the quantity of chlorine to be supplied Ca as being a differential between the collected chlorine content Ce and the set chlorine content Ct.

[0086] Furthermore, the control module 52 controls the respective operation of the electrolyser means 21 and the injector means 22, to achieve the quantity of chlorine to be supplied Ca.

[0087] According to the invention, the control module 52 is configured to distribute the quantity of chlorine to be supplied Ca between the electrolyser means 21 and the injector means 22.

[0088] In this sense, the quantity of chlorine to be supplied Ca is divided into shares which are designated respectively by:

[0089] - a first share Cal, for the share of the quantity of chlorine produced by the electrolyser means 21, in relation to the quantity of chlorine to be supplied Ca, and

[0090] - a second share Ca2, for the share of the quantity of chlorine produced by the injector means 22, in relation to the quantity of chlorine to be supplied Ca.

[0091] Generally, each Cal, Ca2 quota has a value ranging from 0% to 100%, relative to the quantity of chlorine to be supplied Ca. The sum of the Cal and Ca2 quotas is equal to 100% and corresponds to the quantity of chlorine to be supplied Ca.

[0092] For this, preferably, the control module 52 controls:

[0093] - the operating time of the electrolyser means 21, to obtain the first Cal share, or

[0094] - the volume of chlorine to be injected by the injector means 22, to obtain the second Ca2 share.

[0095] To control these shares, the control module 52 comprises in particular:

[0096] - a calculation unit 521, configured to calculate the distribution of the quantity of chlorine to be supplied Ca, between the electrolyser means 21 and the injector means 22 (namely the respective Cal and Ca2 shares), and

[0097] - a control unit 522, configured to control the respective operation of the electrolyzer means 21 and injector means 22, taking into account the aforementioned Cal, Ca2 shares.

[0098] The control module 52 thus advantageously consists of a computer program which comprises instructions which, when said computer program is executed, cause it to control the chlorination means 2 according to configurations described below.

[0099] In other words, the control module 52, and advantageously the calculation unit 521, automatically determines the respective shares Cal and Ca2.

[0100] According to the invention and as shown schematically in [Fig.2], this distribution of the quantity of chlorine to be supplied Ca (namely the respective shares Cal and Ca2) takes into account the collected temperature value Te and temperature thresholds TMin, TMax of the water in said swimming pool.

[0101] Preferably, the temperature thresholds TMin, TMax are chosen from:

[0102] - a minimum temperature threshold TMin ranging from 14 to 16°C, preferably 15°C, And

[0103] - a maximum temperature threshold TMax ranging from 19 to 21°C, preferably 20°C.

[0104] More precisely, the control module 52 (advantageously via the calculation unit 521) is configured to distribute the quantity of chlorine to be supplied Ca according to three configurations taking into account the collected temperature value Te.

[0105] First, the control module 52 is controlled in an “injection” configuration when the collected temperature value Te is lower than a minimum temperature threshold TMin.

[0106] The injector means 22 are then controlled to supply the quantity of chlorine to be supplied Ca.

[0107] The value of the second share Ca2 is then equal to the value Ca (the second Ca2 quota is equal to 100%); 100% of the chlorine is thus injected by the injector means 22. The value of the first Cal quota is zero.

[0108] Second, the control module 52 is controlled in an “electrolyzer” configuration when the collected temperature value Te is greater than a maximum temperature threshold TMax.

[0109] The electrolyser means 21 are then controlled to produce the quantity of chlorine to be supplied Ca.

[0110] The value of the first share Cal is equal to the value of Ca (the first share Cal is equal to 100%); 100% of the chlorine is produced by the electrolyser means 21. The value of the second share Ca2 is zero.

[0111] Third, the control module 52 is controlled in a “hybrid” configuration when the collected temperature value Te is between the temperature thresholds TMin and Tmax.

[0112] By “included”, we advantageously include a temperature range from the minimum temperature threshold TMin to the maximum temperature threshold Tmax.

[0113] The electrolyser means 21 and the injector means 22 are then controlled to each generate a share of the quantity of chlorine to be supplied Ca (the sum of the values ​​of Cal and Ca2 is equal to the value of Ca; the values ​​of the shares Cal and Ca2 are non-zero).

[0114] In this case, the first share Cal (produced by the electrolyser means 21) increases with the collected temperature value Te.

[0115] Conversely, the second share Ca2 (produced by the injector means 22) decreases with the collected temperature value Te.

[0116] Preferably, the control means 5 thus comprise means for implementing the following steps:

[0117] - a step of calculating said quantity of chlorine to be supplied Ca (advantageously via the calculation module 51), taking into account said collected chlorine content Ce and a set chlorine content Ct,

[0118] then

[0119] - a chlorination step (advantageously via the control module 52), taking taking into account said collected temperature value Te and the temperature thresholds TMin, TMax, according to one of the aforementioned configurations (injection configuration, electrolyser configuration or said hybrid configuration).

[0120] Preferably, the control module 52 is configured to continuously or discontinuously increase the first share Cal produced by the electrolyser means 21.

[0121] According to a first preferred embodiment, the control module 52 is configured to continuously increase the first share Cal produced by the electrolyzer means 21, among:

[0122] - a continuous linear increase,

[0123] - a continuous logarithmic increase,

[0124] - a continuous exponential increase,

[0125] - a continuous polynomial increase.

[0126] In the case of a continuous linear increase, the value of the first share Cal can be obtained by the following formula:

[0127] Cal = ((Te - TMin) / (TMax - TMin)) x 100%

[0128] According to a second embodiment, the control module 52 is configured to discontinuously increase the first share Cal produced by the electrolyser means 21, advantageously in the form of stages, for example one stage per degree of temperature.

[0129] An example of discontinuous increase is detailed below:

[0130] - the first Cal share is equal to 0% when the collected temperature value Te is lower than the minimum temperature threshold TMin,

[0131] - the first Cal share increases by 20 to 30% for each degree of temperature temperature, between the temperature thresholds TMin, TMax, and

[0132] - the first share Cal is equal to 100% when the collected value of tem temperature Te is greater than the maximum temperature threshold TMax.

[0133] According to the invention, the control means 5 advantageously comprise an additional calculation module 53, for determining a quantity of additional chlorine Cd to be provided, taking into account at least one additional parameter.

[0134] This additional parameter is chosen for example from:

[0135] - weather conditions which do not allow the electrolyser means 21 to counter the development of bacteria and algae,

[0136] - intensive use of the swimming pool,

[0137] - the status of the electrolyser means 21, in particular the electrodes, in particular in end of life,

[0138] - a salt level in the water which is below a minimum threshold.

[0139] In particular, monitoring weather conditions makes it possible to anticipate the destabilization of chlorine regulation and therefore to anticipate the development of unwanted microorganisms.

[0140] For this, the control means 5 are advantageously associated with at least one interface adapted to the provision of additional information, namely for example among:

[0141] - a human-machine interface (a touch screen or not, a keyboard, etc.) for the entry of information by an operator (for example, intensive use of the swimming pool),

[0142] - means for detecting the status of the electrolyser means 21,

[0143] - means for detecting the salt level in the water,

[0144] - a telecommunications network, for the transmission of meteorological conditions logical.

[0145] In practice, this quantity of additional chlorine Cd to be supplied is supplied by the injector means 22. Pool

[0146] The present invention also relates to the swimming pool equipped with this chlorination installation 1.

[0147] Such a chlorination installation 1 may possibly be integrated into an electrical system dedicated to the power supply and control of the electrical equipment of a swimming pool, which is described in document FR3119186.

[0148] Process for chlorinating swimming pool water

[0149] The present invention also relates to the method for chlorinating swimming pool water, by implementing the chlorination installation 1 according to the invention.

[0150] This chlorination process comprises a succession of steps, illustrated schematically in [Fig.3], namely:

[0151] - a calculation step A, for calculating the quantity of chlorine to be supplied Ca, taking taking into account the collected chlorine content Ce and a set chlorine content Ct,

[0152] - a chlorination step B, taking into account the collected temperature value Te and temperature thresholds TMin, Tmax.

[0153] This chlorination step B is carried out according to the aforementioned configurations:

[0154] - an injection configuration B1, when said collected temperature value Te is lower than said minimum temperature threshold TMin, in which said injector means 22 are controlled to generate said quantity of chlorine to be supplied Ca,

[0155] - an electrolyzer configuration B2, when the collected temperature value Te is greater than said maximum temperature threshold TMax, in which said electrolyser means 21 are controlled to generate said quantity of chlorine to be supplied Ca, and

[0156] - a hybrid configuration B3, when the collected temperature value Te is between said temperature thresholds TMin, TMax, in which said electrolyser means 21 and said injector means 22 are controlled to each generate a share Cal, Ca2 of said quantity of chlorine to be supplied Ca.

[0157] As previously developed, in the hybrid configuration B3, the first share Cal increases with the collected temperature value Te.

[0158] As discussed previously, such a technical solution according to the invention makes it possible to avoid sudden switching between the electrolyser means 21 and the injector means 22, at a threshold temperature.

[0159] On the contrary, it ensures a progressive passage between the electrolyser means 21 and the injector means 22, over a range between two threshold temperatures.

[0160] Preferably, this process comprises a complementary chlorination step B5, taking into account at least one additional parameter.

[0161] This additional parameter is chosen for example from:

[0162] - weather conditions which do not allow the electrolyser means 21 to counter the development of bacteria and algae,

[0163] - intense use of said swimming pool,

[0164] - the status of the electrolyser means 21 21, in particular the electrodes, in particular at the end of life,

[0165] - a salt level in the water which is below a minimum threshold.

[0166] This additional chlorination step is advantageously implemented by the injector means 22.

[0167] Of course, various other modifications may be made to the invention within the scope of the appended claims.
