Description

The utility model relates to the field of automation of control processes for household and industrial cameras of single-function use. In particular, the design of the control unit of the drying chamber is considered, made in the form of a control panel that is built into the drying cabinet, or remotely located in relation to the drying cabinet.

Domestic and industrial chambers for single-purpose use, in particular, under the drying chamber, are understood as automatic drying of clothes and shoes in various climatic conditions using drying systems equipped with blowing of their internal space, heated air currents and subsequent removal of heated air to the outside, as well as processing of dried clothes and shoes with a quartz bactericidal irradiator to disinfect the dried surface and an ionizer to remove and prevent unwanted electrostatic charges.

This drying system comprises a chamber for accommodating items to be dried therein, in which circulation of the drying air flow is organized by taking air from the outside of the chamber and supplying it with air blowing means to the chamber for heating and subsequent removal of the humidified air stream from the chamber to the external environment. The camera is made in the form of a cabinet with elements for hanging clothes to be dried and placing, for example, shoes. Exhaust fans are mounted in the upper part of the cabinet. In the lower part of the cabinet, a thermal block is fixed, which includes means for heating the air coming from outside the chamber and means for pumping heated air into the chamber. The device is equipped with an electronic control system for the circulation of drying air flow, which includes a control panel with manual settings for humidity and temperature, temperature and humidity sensors inside the chamber and actuating units for controlling the on and off heating elements of the heat unit and fans.

Traditionally, in such drying chambers the control system is formed either on one of the walls or on the cabinet door. So, for example, in patent GB 2394271 (D06F 58/10, 58/24, F26B 9/06, publ. 04/21/2004), a drying chamber is described, which is a parallelepiped-shaped housing with a front door, in which drills are made for output to the outside two knobs around which the scale is drawn, for setting the heating temperature and time, and a push-button switch / switch and a rotary organ for setting the fan operation modes. The controls themselves are mounted on the back of the door.

This well-known method of placing control mechanisms with the output of their controls to the outside is used for models of the drying cabinet, which will not subsequently undergo modernization and modification of the model itself. For such drying cabinets, which contain basic equipment that is subject to modernization and the creation of new advanced models, this method of placement of the control system is not suitable, since the new model may have a more expanded range of modes and, accordingly, a different set of control mechanisms. For this purpose, it is desirable that the drying cabinet itself with a full set of actuating units have the ability to change the control panel.

So, the control panel is known, made in the form of a separate unit attached to the cabinet, on the front wall of which the control elements are brought out: on / off, setting the heating temperature and operation modes of the fans (WO 2005/026427, D06F 58/14, publ. March 24, 2005). This decision was made as a prototype.

The disadvantage of this solution is that this unit is mounted on the wall of the drying cabinet, while the wires remain brought out, which is not safe for users and clearly violates safety requirements. In addition, the known unit does not allow to control the passage of the drying process and does not show the current values of the drying parameters.

This utility model aims to achieve a technical result, which consists in improving the safety of use.

The specified technical result is achieved by the fact that the control panel of the drying chamber, containing a parallelepiped-shaped case, on the front wall of which the power on / off controls, temperature settings for heating the air volume inside the drying chamber by the heater and operating modes of at least one fan are displayed, and on the back wall of which there is a terminal block connected to the power source for connecting wires from the power source, heater, thermal switch, it is intended protection against overheating and emergency power off, and at least one fan, and inside the case there is a processor unit equipped with a probe of a temperature and humidity sensor mounted on the back wall of the case. The case is made of polymer with the possibility of panel mounting in the wall or door of the drying chamber and installed in a metal casing with holes with insulating rubber glands, and the front wall is made in the form of a touch panel with LED indicators of measurement units, buttons for entering the editing mode and setting temperature settings , hysteresis of temperature, relative humidity and drying time, buttons for starting operation and switching to pause mode, and a manual switch on the circuit breaker against overcurrent in the load. At the same time, the processor unit is capable of implementing the function of sequentially demonstrating the current temperature, humidity and time parameters, signaling information about the beginning and end or temporary stopping of the drying process in the pause mode, and storing the settings in memory when entering the editing mode and setting the settings by pressing the button menu.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present utility model is illustrated by a specific example of execution, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the required technical result.

In FIG. 1 is a general view of a drying chamber control panel;

FIG. 2 - view of the rear panel of the remote control;

FIG. 3 is a block diagram of a control panel.

According to this utility model, a panel design is considered which is intended to control the drying process with control of temperature, relative humidity and duration of the drying process. The remote control maintains the set temperature in the drying chamber by controlling heaters and fans. Moreover, when the heater is operating, the exhaust fans are turned off, and when the heater is turned off, when the set temperature is reached, the exhaust fans are turned on. This method of pulsed operation allows for a uniform drying process by evaporation and drawing of moist air from the chamber. The drying process ends either when the set (set) drying time is reached, or when the humidity in the drying chamber reaches the set value.

According to this utility model, the design of a drying chamber control panel is considered (Figs. 1 and 2), which includes a parallelepiped-shaped housing 1 mounted in a cutout of a cabinet wall or door in a metal casing with openings insulated with rubber glands. On the front wall 2 of the casing, the controls for turning on / off the power, setting the temperature for heating the air volume inside the drying chamber by the heater 3 (TEN) and the operating modes of at least one fan 4 are displayed outside, and on the back wall of which there is a terminal block 5 connected to the power source for connecting wires from a power source 6, a heater 3, a thermal switch 7 and at least one fan 4. The housing is made of polymer with the possibility of panel mounting in the wall or door of the drying chamber .

The remote control is made with a circuit breaker against overcurrent in the load, with the ability to manually turn on from a button or switch or switch 8.

There is a probe 9 of the temperature and humidity sensor, mounted on the back wall 10 of the housing.

The front wall 2 is made in the form of a touch panel 11 with LED indicators 12 units, buttons 13 ("Menu") to enter the editing mode and 14 (+ -) settings for temperature, hysteresis, relative humidity and drying time, buttons 15 (“Start”) the beginning of work and 16 (“Pause / Stop”) the transition to pause mode and stop the drying process.

At the same time, the processor unit 17 (Fig. 3) is configured to implement the function of sequentially demonstrating the current temperature, humidity and time parameters on screen 18, signal information about the beginning and end or temporary stop of the drying process in the pause mode, and storing the settings in entering the editing mode and setting the settings by pressing the "Menu" button.

The following is an example of a concrete implementation of a utility model.

Structurally, the control panel is a sealed monoblock (moisture-proof), made on the basis of a plastic shield housing with slot dimensions in the shield for installation: 84 × 84 mm and a depth of 70 mm (Fig. 1).

The functional walls in the remote control are the front (front) and rear (back) walls.

On the front panel (Fig. 1) of the remote control are located:

- indicator 18 for indicating temperature, relative humidity, operating time, as well as settings in programming mode;

- LED indicators of units of measurement 12;

- indicators 19 turn on the heater, fan, network, drying process;

- buttons (from rubber) 15, 16: “Start” to initiate the beginning or continuation of the drying process, “Pause / Stop” to temporarily stop or end the drying process;

- buttons for entering the editing mode and setting the settings 13, 14 (programming mode buttons);

- automatic 20 protection against overcurrent in the load.

On the back of the case (Fig. 1) are located:

- probe temperature and humidity sensor 9, hermetically attached to the housing;

- terminals 5: for connecting power, heater (TEN), fan and thermal switch;

- button 10 with fixation to lock these settings in the editing mode and setting the settings.

The block diagram of the console is shown in FIG. 3.

The remote control is installed in the cutout of the front panel of the cabinet and secured by the brackets attached to it. To isolate the remote control housing from the internal chamber volume and reduce the effect of increased temperature and humidity on it, a metal casing with holes with rubber glands for the temperature and humidity sensor probe and cables are used: to the power source, to the heater, to the fan and the thermal switch. On the inside of the casing, it is necessary to fix the thermal switch of protection against overheating. Run the cables: mains voltage, from the heating elements and fans into the internal cavity of the casing. Connect the cables to the terminal block of the remote control. Connect the wires from the thermal relay to the remote control. Secure the plug part of the terminal block. Apply power to the remote control through the voltage transformation unit 21 of 220 V to 12 V. Set the required settings. Press the lock button for changing the settings on the back of the housing. Fasten the casing with screws to the inner surface of the chamber. The remote is ready to go.

To enter the editing mode, press and hold the Menu button for more than 1 s. The variable parameter will flicker. If changing the parameters is blocked, then when you try to change them, the entire line will wink. The sequential switching between the parameters is performed by the “Menu” button. When moving from one parameter to another, the value of the previous one is written into memory.

The following parameters are available for editing: temperature setpoint ° C (default value 30 ° C), temperature hysteresis in ° C (default value 3 ° C), relative humidity set point in% (default value 40%), drying time (hours and minutes, default value is 01 hour 00 min). Changing these settings can be blocked by a latch button located on the back of the device. Entering the editing mode is not possible during the drying process and, conversely, the drying mode is blocked in the editing mode. The time spent in editing mode is 30 s. After this time, exit from the editing mode with saving all the settings made.

The indicator operating mode is sliding: temperature, humidity, time (in turn, for example, every 5 seconds, the readings on the display change, first the temperature then shows humidity, then time).

When you press the "Start" button, the inscription: "Star" appears on the display, indicating the start of the drying process. If you press the “Pause / Stop” button, the drying process will be suspended. A blinking PAUS will appear. You can resume the drying mode by pressing the “Start” button again (“cont” will appear). After the drying time has expired or when the humidity reaches the set threshold (with an additional time of 30 s), the process will be stopped, “End” will appear on the indicator. In the event of a sensor failure, “SHtE” will appear on the indicator. In the event of a short circuit in the load circuit, the circuit breaker will trip. After closing the circuit, the machine button must be pressed until it locks.

Programming and viewing the settings is performed as follows. By repeatedly pressing the "Menu" button, you can view sequentially the settings: temperature + hysteresis, humidity, time. Using the buttons - and + you can change these parameters. Each subsequent press of the "menu" button leads to the storage of the changed parameter.

That is, after pressing the "Menu" button, the Temperature column opens (in it, using + and - you can set the temperature parameter, for example, set it to 40 ° C), press the Menu button again, thereby remembering the parameter.

Then we press the Menu button again and we get to the Temperature hysteresis section (there, using + and - we select the temperature parameter range, upon reaching the upper limit of which the heater will turn off and the exhaust fan will turn on, and when the lower limit is reached, the heater will turn on and the exhaust fan will turn off fan), then press Menu and the parameter is remembered.

Then we press the same “Menu” button and get into the Humidity section (there we set + and - the humidity parameter, after which the system turns off, then we press the “Menu” button and the device remembers the humidity parameter.

Then we press the same “Menu” button and get into the Time section (set, if necessary, the time after which the system will turn off completely), set the parameter, press the “Menu” button again to store the parameter.

Camera control is carried out by simply pressing the "Start / Stop" button. We click on the button, the drying process begins according to the specified algorithm, time goes on, press again - the drying process stops. Also, the drying process stops automatically when the set humidity is reached and after the set time has passed. The light on the remote control is on: the network shows that there is power and you can program the remote. After pressing the “Start” button, the drying process itself begins (DRYING lights up). When the heating is working, the heater is lit, when the fan is running, the VENT is lit. Upon completion of the process, DRYING ceases to burn, you can open the cabinet door and remove clothes or repeat the process or completely turn off the system.
