The primary object of the present invention is to obtain a simple and economical structure applied to a manual hair dryer which is capable of recording and communicating a plurality of operation and function parameters, and thus being programmable and having a plurality of functions.

Another object of the present invention is to change the operating conditions and cycles of the device, and to store and display control information of the factors governing the operating performance, such as the flow rate of the discharge air, the temperature, the cold and the temperature change, and others described below. It is to provide a manual hair dryer including a circuit.

In short, the dryer comprises a circuit comprising a temperature sensor, a pressure sensor, and a microprocessor controlled by software which receives information from a group consisting of control of motor rotation and values selected by the user. On the other hand, the memory also records the parameters selected and measured by the circuit, records the operating time of the device and checks whether the selected values correspond to the performance of the electronic components of the circuit.

To successfully achieve these functions, the microprocessor is programmed not only to adjust the control variables but also to continuously check the motor speed to manipulate the acceleration state. Another important parameter is the current circulation through the exothermic resistance, the value of which is adjusted to control the temperature of the discharged air. This activates all the light emission control parts which display the operation state via the program level indicator, and displays all the current setting values on the display device. Factors to be measured from this are the circulation of the air flow in the device, the output temperature, the rpm of the motor, the service time, the current consumption and the voltage of the motor and the heating resistance.

The critical values are wasted power and motor revolutions, the maximums of which are described in the product information to avoid exceeding.

The program permanently maintains a record of the operation of the device. This record includes the total cumulative operating time, including the exact date of warranty and the initial time of use to establish operating conditions.

[Prior art]

Conventionally, many structures and designs that are applied to so-called manual hair dryers are known. Most of the conventional hair dryers are designed to satisfy a specific purpose for the method of distributing and using the discharged air stream. Accordingly, nozzles of various shapes that can be exchanged have been developed, and these nozzles are attached to the air discharge pipe. This nozzle improves the expected results by concentrating or diffusing the air flow. These attachable members may consist of various types of combs or brushes that meet the needs of the hairdresser.

This kind of functional change for the dryer is generally limited to adding an on / off switch to the air heating unit and selecting the maximum or minimum amount of air acting on the motor speed.

Other special requirements were embedded in large commercial hair dryers.

Each of these elements has features to accomplish its purpose, among which programmable control circuits include a microprocessor, which comprises at least one temperature sensor, a static pressure sensor, a motor rotation sensor, an ion generator, a series of A resistance battery having a selection switch, a power supply circuit of the motor, and the above-mentioned air heating device are connected.

To optimize the processing means, once the dryer is powered on and the operating value of that parameter is selected, the microprocessor sets the initial operating configuration to a value of 50%, and then the electrical, In response to thermal and mechanical inconsistencies, certain functional conditions are continuously defined against a normal database and recorded, signaled, and displayed using a display.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings so that the present invention constituting a programmable multifunction manual hair dryer can be understood and practiced. The drawings are exemplary and do not limit the invention. The parts can be selected from a variety of equivalent parts without departing from the principles of the invention.

In Fig. 1, the circuit taken as an embodiment of the present invention consists of an integrated circuit of the type "Peripheral Interface controller 16F873" or similar integrated circuit. The circuit is connected to an electric motor 2, which drives the dryer through a transistor 3 whose collector is connected in series to the triac 4. The motor-triac series sic houses a power supply 5 comprising a conventional capacitor and resistor.

Likewise in other similar circuits, the processor is connected to a heating resistor 6.

The circuit has a connection corresponding to a temperature sensor 7, a filter sensor 8, a pressure sensor 9 and an optocoupler sensor 10 which receives the rotational speed of the motor.

The device controls the corresponding parameters such that a power source 11 comprising the necessary components, such as rectifier diodes, zener diodes and electrolytic filters, is configured by means of electrical diagrams. The device adds associated circuit components, such as limiting resistors and capacitors, which supply a signal to a resistive battery 12 in series with the selector switch 13.

The operating status can be confirmed using a liquid crystal display 14 which provides an indication of the speed and temperature VU meters.

2 shows a method of placing parts in a housing of a manual hair dryer. Each basic component, such as a motor speed detector with a motor 2 and an optocoupler 10, is marked in the same way. The motor drives the turbine 15, which discharges air through the front nozzle 16. Here, a filter 17 having a heat generating resistor 6 having a heat detection thermocouple 7 and a pressure sensor 9 is provided. Moreover, the plate provided with the electronic component of a circuit is provided.

In the handle portion of the housing is arranged an ion generator 18 having a corresponding emitter electrode 19 arranged in the nozzle 16. Further, elements such as an ion generator operating selector for forming a push button corresponding to the keyboard 10, the temperature range, the speed, and the switch 13 are further provided in the handle portion.

The display device 14 in the handle displays the functions and values of the parameters involved in the function of the device, the data stored in the memory and the menus to be provided.

Since the voltage handled is very low, there is no inconvenience or risk of installing the switch 13 for controlling the operation of the dryer through the microprocessor 10 to the handle.

FIG. 3 shows a flowchart, which sets the configuration 22 of the initial function at start (power on) or start 21 and adjusts the value of the parameter to 50%. Once the operating parameter 23 has been determined, the input with operating configuration 23 is set and the state of the parameter is set 24. The operation state of the function is displayed on the display device 14.

The operating state is controlled by comparing with the parameters of the database (25). Here, a filter such as the filter replacement alarm 27 or the filter 8 member alarm determined by the electromagnetic pressure sensor 9 and the limit of the range of possible high temperature values 26 detected by the thermocouple 7 from the temperature A. Problem alarms are set. The problem of the motor is indicated by the motor brush replacement 28. This is done by identifying normal and cumulative operating times in the database.

Motor speed control 29 and temperature control 30 are executed in response to sensor recordings 31 and 32 provided by respective elements 10 and 7. This control result is displayed by the instructions 33 and 34 connected to the display device 14, the speedometer and the temperature VU meter.

The counter step 35 and the recording step 36 are reached through subsequent steps from the initial state of the flowchart. This recording step compiles most of the important data regarding the operation, maintenance and control of the dryer.

The flowchart shows the relationship present in the output 37 of the controls 29 and 30 and the information input 38 to the (sic) parameter state 24 described above.

[work]

Hereinafter, the function and operation relationship and operation results of the set components of the present invention will be described.

1 and 2 show a circuit and an apparatus composed of a plurality of parts which enable the implementation of the invention in one embodiment of the invention, and the flowchart of FIG. 3 shows detailed instructions for a program developed as a preferred embodiment. To show. 4 and 5 illustrate how the dryer operates over time under various conditions.

In the first use of the dryer, the dryer is set at the initial "0" point, and in the absence of a filter (since the filter is provided separately), the sensor indicates no filter on the display and prevents the motor from starting. The sensor reacts in the same way even if the filter is incorrectly installed so that the dryer does not operate when the power switch (button) is pressed several times.

When the filter is mounted, the sensor detects it and sends a signal to the microprocessor. The microprocessor records and displays the date and start time of use of the dryer from zero hours. These data are stored in memory and can be reused when the dryer is powered on.

When the dryer is powered on, the heater is gradually accelerated and the heater is gradually heated until the temperature initially set at the factory is reached. The purpose of heating at such a preset gentle speed is to extend the service life of the parts of the dryer.

When the operating state of the dryer reaches the "set temperature" and the selected amount of air, the curve is stabilized by reaching point 1 in the Cartesian diagram of FIG. 4 and remains constant throughout the dryer's full service time. The dotted line represents the selected operating value on the x axis. Conventional dryers define the locations indicated in the control, but do not provide information about changes that may occur during use. Instead, the flow rate and temperature change occur due to external condition change that will not occur in the dryer of the present invention.

Changing to the desired flow rate moves to point 2 in FIG. 5 without temperature change. To satisfy this, the motor speed is increased to decrease the temperature at the outlet of the dryer (a). The sensor corresponding to this detects this, and the microprocessor commands the current increase of the resistor to raise the predetermined value to compensate for the temperature decrease, and then returns to the preset value. This change is reflected in the corresponding curve.

In conventional dryers it is not possible to make such modifications via an open loop operating system where the actual flow of the dryer outlet is unknown.

An example of temperature change is simply that the microprocessor regulates the energization of the heating resistor and limits the maximum temperature to protect the circuit. This is not possible even if the user attempts to reset the maximum temperature value, and the display indicates why the temperature value cannot be reset by saying that the temperature is very high for the current flow rate.

It is assumed that there is no change in the variable, but a change occurs due to an external condition, for example, a change in external condition such as a partial blockage of the filter (see FIG. 6). When this happens, the flow rate decreases and the temperature rises. To compensate for this change, the microprocessor commands the motor to rotate at high speed to maintain the original flow rate. When the flow rates are balanced, the temperature stabilizes without further adjustment.

In the same graph, one can imagine the case where the filter is more seriously occluded. In the diagram, the first occlusion is located between point 1 and point 2, and the second occlusion starts at point 3. The modification here is made with the same logic as described above. However, when point 4 is reached, the motor becomes overspeed in the relationship between the flow rate and the rpm of the motor, the current supply is interrupted at that point, and the dryer is completely stopped. At the same time the display shows the indication "Filter change". Then, the dryer can not be used and can be reused after replacing the filter. This situation is detected by the filter sensor. In other words, filter replacement is necessary to make the dryer reusable. The filter change situation made during the use of these processes and the dryer is recorded and stored in the computer memory.

The contents of the analyzed chart are stored in the memory as set in the steps indicated by the counter 35 and the record 36 in which the normal and possible operating states occurring during use of the dryer are recorded. Thus, the operating history of the dryer is recorded and all the necessary information for the best operation of the dryer, such as filter replacement, motor bearings and the like, as well as repair work, is displayed on the display device 14.

In summary, the command circuit includes a microprocessor. This microprocessor is connected to the electric motor of the dryer via a transistor. The collector of the transistor is connected in series to the triac, and the motor-triac series has conventional elements, capacitors, resistors and the same electrical arrangement (configuration) as the conventional one. Exothermic resistance is supplied with electricity; The microprocessor is connected to a temperature sensor, a filter sensor, a pressure sensor and a motor speed sensor; The circuit has a display member, an adjustment member, and a connection member of operating parameters of the device controlled by the microprocessor and controlled by a program.

The foregoing has described the possible embodiments and specific application states in which the present invention can be implemented.

According to the present invention, a user can record and communicate with a plurality of operation and function parameters, thus obtaining a programmable and manual hair dryer having a plurality of functions. will be.
