Device for the electronic control of the

Operating sizes of a swimming pool system.

Description The invention relates to a device for electronic Control of a swimming pool system according to the preamble of claim 1.

Under swimming pool systems, components that can be manufactured from transportable parts become Swimming pools, especially so-called whirl pools, but also on the spot Completely erected swimming pool systems usually together with filter systems Understood.

In the case of such known swimming pool systems, there is generally a desire a certain bathing temperature or actual temperature of the pool water regardless of the environmental influences, in particular air temperature, fresh water inflow, heat dissipation to be kept constant by evaporation and heat conduction to the environment. on the other hand there is a general and especially at times of high energy costs, the desire to Heating the pool water to keep the heating energy used as low as possible.

For this purpose it is already known to measure the temperature of the pool water to keep a temperature controller approximately constant by changing the temperature difference between a setpoint temperature that can be set on the temperature controller and the respective The actual temperature of the pool water is formed and the heating output accordingly the difference is set automatically. To energy outside the real To save bathing times, it is also known to set the target temperature, for example manual adjustment of a setpoint device of the temperature controller. It It can also be thought of lowering the target temperature by means of an electromechanical Control timer.

The disadvantage here is that by lowering the target temperature the desired bathing temperature is not easily reached at the beginning of the bathing time becomes, if not to be accepted, that the desired bathing temperature has been heated up for a long time before the start of bathing time, but what a can mean a corresponding waste of energy. To make matters worse, the Time at which from a lowered target temperature to the target temperature for Reaching the desired bathing temperature or actual temperature during bathing time is switched, often only relatively cumbersome, for example on one Timer and remote from the target temperature sensor can be made. The point in time at which the switchover from the lower target temperature to the higher one The target temperature during the heating-up time or bathing time cannot be avoided either further through the dimensioning of the time-controlled means1, in particular setting anticipate a timer by the manufacturer or supplier of the swimming pool system, if the entire control device for optional use with different Swimming pool systems is manufactured. In addition, local and installation conditions Deviations from a normal presetting of the time-controlled means are necessary do.

The object of the present invention is therefore to provide a device for the electronic control of the operating parameters of a swimming pool system mentioned genus in such a way that it can be used as universally as possible for different swimming pool systems and with different adjustable bathing times and bathing temperatures ensure that the pool water is heated as efficiently as possible is achieved in such a way that the desired bath temperature or

Set the actual temperature of the pool water at the beginning of the bathing time.

This task is covered by the characterizing part of the claim 1 specified invention solved: It is essential in this device that not only the point in time of switching from a reduced setpoint to a higher one The setpoint can be set variably during the heating-up time or the bathing time and the target temperatures for controlling the temperature of the pool water during the heating and bath time and outside of these times are adjustable, but that beyond Means are provided with which, depending on the temperature difference between Presettable target temperature for bathing time and the current actual temperature the heating time is determined automatically and based on the adjustable desired start of bathing time, taking into account the heating-up time Heating starts in time to reach the desired bathing temperature, but do not start heating up prematurely, in order to keep the energy requirement low to keep. The device according to the invention is characterized in that taking into account the pool water temperature prior to heating the heating time is varied automatically so that at the beginning of the bathing time the desired temperature is reached. In addition, the shortest possible energy-saving Heat-up time determined. This determination can be done by a different for many Equipments for electronic pool systems that can be manufactured in accordance with the same Control takes place by storable in the device with a single Value the pool-specific deviations are taken into account.

This facility is also energy-saving because during the heating is only switched on once during the entire heating-up period, i.e. none Control with successive switch-on and switch-off and corresponding cooling down of the pool water enters. - Because the value of the beginning the bathing time and the adjustable swimming pool system-specific value in memory parts a combined memory in one device takes place, this facility set conveniently. The target temperature can also be specified on the same device for the bath time and the lowered target temperature, which is also called the economy temperature is designated.

It is also particularly advantageous that apart from the swimming pool system-specific Value no other data to be manually fed in to determine the heating-up period because the temperature difference otherwise used for regulation is used here for determination the heating-up time is used.

The pool system-specific value is particularly advantageous stored in the second memory part according to the dimensioning specified in claim 2. This swimming pool system-specific value is essentially made up of the constants the installed heating power and the heat capacity of the pool water to be heated certainly. The specified relationship applies to a heating-up time measured in minutes. By slightly varying the swimming pool system-specific value k, the Supervisors of the swimming pool system still introduce improvements to the desired bathing temperature at the beginning of the bathing time exactly without unnecessary heating.

According to claim 3 is in the same common memory but in a third memory part feeds a value of the lowered setpoint temperature, with the outside of the bathing time and the heating-up time an energy-saving low one The temperature level of the pool water is maintained. Switching to the low one The temperature level outside the heating-up time and bathing time takes place automatically by the time-controlled control unit.

In an embodiment of the device according to claim 4, this can also used to automatically comply with several preferably four filter cycles in which the pool water is filtered. After entering the start times and duration of the filter cycles, which is conveniently carried out on the central device, the filter cycles can run automatically.

An even more extensive design of the device, so that this can also be used to trigger pure switching functions for a fan, a lighting device Also suitable for manual operation is specified in claim 5. Switching from Manual operation to automatic operation takes place conveniently by pressing a sensor button, with which, in particular, the control unit is set. This allows the individual Combine switching options of the facility for maximum ease of use. at When the sensor button for automatic mode is switched on, the temperature of the pool water is set automatically regulated to the desired temperature during bathing time and outside of bathing time it is lowered to the economy temperature, which is also regulated can be adhered to. Controlling the economy temperature not only generates energy saved, but constant heating times can be expected. Also at The pool water is automatically controlled before the start of the bathing time heated up. The filter cycles also run during the same "Automatic" operating mode away.

In claim 6 it is indicated that the in the various memory parts values stored for control and / or regulation and beyond that those not stored actual values in particular the actual temperature with a liquid crystal display are representable.

By designing the sensor keys as a waterproof membrane keyboard according to claim 7, the central device can with these sensor keys in compliance of the protective regulations are set up in the immediate vicinity of the pool edge and is therefore easily accessible.

The invention is illustrated below with reference to a drawing with 4 figures explained in more detail. 1 shows a schematic block diagram of the device, Fig. 2 is a flowchart illustrating the control process for the heating period, 3 shows a plan view of a sensor key arrangement and display panel of the device and FIG. 4 is a diagrammatic representation of the device with a sensor key adjustable swimming pool system-specific value In Fig. 1 are generally with 1 sensor keys the desired values or functions in the device for electronic Control can be entered, as will be described in more detail below. The meaning of the values or functions results from the labeling of the sensor buttons in Fig. 1.

The actual appearance of an embodiment of this sensor key arrangement is shown in FIG. 3.

In Fig. 1 are keys that are functionally seen in context can, summarized with a bracket. A first group, which is shown in Fig. 3 with "temperature" is designated, a sensor button 2 holds the actual temperature, a setpoint button 3 for the setpoint temperature during bathing time and a sensor button 4 for an economy temperature or a reduced target temperature.

There is one in another group for specifying the filter cycles Sensor key 5 for the filter time, one sensor key 6 for the start of the filter time and a sensor button 7 next to each other for their duration.

Sensor buttons 8 and 9 are used to increase a preset value or smaller.

A sensor key 10 is for entering a swimming pool system-specific Value, which is designated as P / Q, provided.

Further sensor buttons 11, 12, 13, 14 are used to trigger switching functions in manual mode, i.e. to switch on a filter circuit, a fan, a Lighting system or a pump.

A sensor button 15 is used to specify the start of bathing time, i.e. a start time shown. A sensor key 16 is a superordinate key which is operated with one of the other keys when the input values are changed. A sensor button 17 is used to switch from automatic mode to manual mode. One Sensor button 18 labeled "clock" is used to set a time while a last sensor key 19 is provided for switching the device on and off.

From Fig. 3 it can be seen how these sensor keys in two rows 9 buttons each are grouped one above the other and can be easily operated.

The entire device is switched on and off with sensor button 19, while a timer 20 continues to run.

When switching off, all stored in the facility remain Values preserved.

The program key 16 is to be pressed before any values or Data can be saved with the special sensor buttons. It serves as protection against accidental adjustment of the facility.

By pressing the sensor button 15 after pressing the sensor button 16 becomes a start time, i.e. the start of the desired bathing time in a general with 21 designated memory entered, namely in the first memory part 20th

The sensor keys are used to enter this start time and other values 8 or 9 are used in conjunction with a numerical encoder 23, which controls the numeric value generated. This numerical value can be changed by pressing the sensor buttons 8 or 9 can be set larger or smaller. The numerical achieved in each case The value is shown with a display device 24, which acts as a liquid crystal display device is formed, shown. For this purpose, a display control 25 is actuated the sensor button assigned to a function, here sensor button 15 for the start time activated so that the numerical value set for the start time is activated via the display control 25 is forwarded to display 24. - The display controls act accordingly also when entering other numerical values together.

It should be noted at this point that the sensor key 2 is only used for control the display control 25 is provided for displaying the actual temperature and not for storing an actual temperature in the memory 21.

A target temperature that the pool water will reach during the heating-up time should be heated up and should be kept during bath time, can by pressing sensor button 3 after sensor button 16 in a further memory part 26 save.

A lowered setpoint temperature is stored in a similar way or an economy temperature with the sensor button 4 in a so-called third memory part 27

In a so-called second memory part 28, a swimming pool system-specific value k is stored by actuating the sensor buttons 17, 10, 8 or 9, which is also referred to as P / Q, since it takes into account the installed heating power P and the heat capacity of the pool water according to the following relationship : k = m. c. 60 3.6. P where: m = mass of the pool water kg c = specific heat capacity r kJ) .Ed CKs The relationships between the value k (abscissa) and the installed heating power P (ordinate) as well as the water volume of the pool water (parameters of the family of curves) is shown in FIG.

The values k to be set can also be tabulated for various Heating outputs and pool water capacities set up and made by the user A table can be read off by pressing the sensor buttons 8, 9, 10 in the second memory part 28 to be entered.

To enter the target temperature and the economy temperature with the Sensor buttons 3 and 4 must be added that here too the sensor buttons 8 and 9 are to be pressed for larger and smaller numerical values. The economy temperature respectively.

the lowered target temperature is expediently 5 to 8 "depending on the size of the pool and connected load of the heating device is set below the target temperature. This is to ensure that in the times outside of bathing time and during the heating-up time, the pool water cannot cool down enough that the automatic Heating becomes impossible.

To save four filter cycles, further memory parts 29, 30, 3l, 32 ', those with the sensor buttons 5, 6 and 7 in a functional context stand: After pressing sensor button 5 once for the filter time, appears in the display device 24 the first initial value of a first filter cycle, the can be adjusted to the desired value using buttons 8, 9. Through each Pressing sensor button 5 again will always use the next starting value of the other Filter cycles shown and can, if necessary.

be changed. During the filter time entries above Pressing the sensor button 5, the sensor button 6 can also be pressed to the To show the filter duration of the corresponding cycle with the display device 24. These The duration of the filter cycle can also be influenced by pressing sensor buttons 8 and 9 will. When the desired filter duration is displayed, this value can be scrolled through Press the sensor button 7 for the corresponding filter cycle in one of the other Feed in storage parts 29 - 32.

It is now assumed that all required values are now in memory 21 are included.

The further functional sequence is controlled by a control unit 33, which, however, also when saving of values and could be used when displaying them. The control unit 33 receives, among other things Commands from the sensor button 17 for manual / automatic mode, from the timer 20, whose Setting can be adjusted by means of sensor key 18, by means of the sensor key 19 for switching on and off as well as through the memory 21 and a yet to be described Arithmetic unit 34.

So much for a few links between the control unit and the other function groups of the facility are not mentioned here, as is the case with the rest of the description the device according to FIG. 1, it must be taken into account that this is a schematic Model acts.

The device also includes the arithmetic unit 34 in which areas 35, 36, 37 and 38 are shown. The area 35 acts in conjunction with a Reference junction 39 as a direct controller, which sends a signal corresponding to the temperature difference between target temperature or economy temperature and actual temperature - from a temperature sensor 40 delivered - forms, this.s signal of the temperature difference with a predetermined Time response and amplified to an actuator 41 - section heating - to the conventional Temperature control forwards.

This temperature control during bathing time with the target temperature or outside the bathing time and heating-up time with the economy temperature is activated by the Control unit 33 activated.

A special feature in connection with this regulation is the heating of the pool water to the actual temperature required for the bathing time: The one for this The control process in progress is described with reference to FIG. 2: In the value # end shown in block 42 corresponds to the flowchart of FIG the setpoint temperature which is stored in the storage part 26 in FIG. 1. In one Block 43 is the difference between this target temperature and the actual temperature #is formed. The block 43 thus corresponds to the comparison junction 39 in FIG. 1.

The temperature difference signal is stored in a register A. A swimming pool system-specific value P / Q, which is shown in a block 45, is stored in the register B corresponding to the memory part 28 in Fig. 1 and multiplied by the memory content of register A: block 46.

The product is reduced by the quotient 100 for display purposes only. This product, which is formed in section 36 of the arithmetic unit, determines the heating time depending on the temperature difference and the swimming pool system-specific Value. This product is also temporarily stored in register A. - Around to determine the switch-on time of the heating is cached by the Start time - blocks 47, 48 or memory part 22 in FIG. 1 - the switch-on time subtracted: block 49. From reaching the from the difference between the start time and the Switch-on time Tein is set via the actuator 41 in Fig. 1. The heating is switched on until it is reported at decision point 50 is that the actual temperature has reached or exceeded the target temperature has In the status "automatic" by pressing the sensor button 17 are also the filter cycles by comparing the values stored in the memory parts 29-32 activated in the calculator with the current time. This is the filter cycle controlled by the actuator 41 - section filter.

The functions described can run automatically if the Sensor button 17 was pressed to specify the "Automatic" status and then the individual automatically running functions were predetermined by actuation the sensor keys assigned to these functions, for example 11 "Filter", or 3 "Setpoint temperature", or 4 "Economy temperature".

If, on the other hand, manual mode is specified with sensor button 17, then the automatic controls and regulations described, among other things via the Control unit 33 switched off.

The switching functions "Filter", "Air", "Light", "Pump" by activating one of the sensor buttons 11 to 14 in conjunction with the Actuators 41 take effect. - blank page -
