Description

The utility model relates to electrical engineering, namely to humidifiers for creating an artificial microclimate and air conditioning for such premises as living areas, offices, facilities for physical exercises and can be used to expand the physical, intellectual and adaptive capabilities of the body.

Humidifiers are widely known in science and technology and are widely used to increase the relative humidity in the room by saturating the air.

The most famous humidifiers are hot steam generators, the design of which involves placing inside the tank a container of water that is in thermal contact with a heating element that evaporates water in the tank and directs the steam through the spray gun to the outside of the cabinet to be treated.

Currently, there is a tendency to expand the functionality of air humidifiers by giving them additional capabilities, including by expanding the control function.

Known, for example, an air humidifier containing a housing, a water tank, an ultrasonic transducer for generating a stream of water vapor in the inner vessel, an opening in the housing and a diffuser with a vapor phase outlet mounted on the opening, contains a porous liner impregnated with perfume located in the diffuser such so that water vapor rises along the insert in front of the outlet (patent CN1862128, 2006).

The known device is compact and autonomous, but does not provide for the possibility of regulating the humidity of the room.

An air humidifier is also known, which contains a water tank inside the body, an ultrasonic transducer that vibrates in the water of the tank and generates a steam stream in the inner chamber communicating with the hole in the body, as well as a diffusion nozzle mounted on the said hole and containing a steam outlet, said nozzle contains an inner part of an elongated shape made of a porous material that can be impregnated with a volatile aromatic substance, with the possibility of passage ApoB flow along its walls, which then flows into said outlet (patent RU 2395755, 2007).

The known device also does not provide the ability to control humidity in the room.

Humidifiers are also known that have a system that prevents liquid spatter. For example, an air humidifier is known that contains an air duct, a fan, pallets filled with water, adjacent to the air duct and communicated with it through slots, the pallets are located one above the other and are made with holes in the sides having a local lowering and forming slots with the bottom of the higher pallet for air inlet and outlet, while the sides of one hole form a duct, and the sides of another hole form a channel for draining water, the duct is closed from below by a lid having an opening with sides, and the walls of the pallets are They are not stepped and form the body of the humidifier, the slots for air outlet are equipped with splash-proof dampers, the fan is located above the air duct, the humidifier is equipped with a water tank (patent RU No. 60683, 2007).

Known humidifier have limited functionality, because there is no possibility of regulation of humidity in the room.

A device is known for controlling the levels of characteristics of an artificial microclimate in a room, comprising an interface connected to a microclimate control unit, including, firstly, a memory controller that stores program commands for controlling the operation of the microclimate control unit by generating control signals, a timer associated with controller to synchronize events related to the control of artificial microclimate and including the generation of control signals and receiving signals, representing which represent the levels of characteristics in the room, an input device connected to the controller for inputting at least one of the set control points, an artificial microclimate characteristic sensor connected to the controller, for outputting at any given time a signal representing the level of characteristics in the room, sensor the presence of people associated with the controller to send a control signal to the controller, the controller’s memory also stores data on the drift and control dependencies, on a given control point, before which sets a given level of performance, about the specified maximum and minimum ranges near the control point and about the specified maximum recovery time, and according to the control signal from the sensor for the presence of people in the absence of people in the room, the level of the characteristic drifts towards the level of the environmental characteristic in the room adjacent to it areas, and if there are people in the room, the level of the characteristic in the room is shifted in the direction from the level of the specified characteristic environment, while the program commands include drift resolution only within the maximum range when there are no people in the room, and then, in the event of people appearing, activation of a controlled shift of the characteristic level in the room towards a given level of characteristic within the minimum range near the control point, moreover, the maximum range is limited so that for the microclimate control unit the amount of control time required to shift the level of microclimate characteristics in the room from m ksimalnogo range to a predetermined level not greater than a predetermined maximum recovery time (patent RU 2141081, 1999).

The known controlled device relates to a complex air conditioning system, including a heating unit, an air conditioning unit, a ventilation unit, a humidifier and a dehumidifier, a degassing unit, which makes it possible to control the humidity level and temperature in the room, i.e. Suitable for use in sports. However, the known device has a significant overall dimensions, inaccessible to a significant part of consumers, because require significant installation and maintenance costs during operation.

The known device is compact and contains controls. However, the controls do not provide humidity control in the room, including through remote access.

As can be seen from the description of the prior art, a significant number of different types of humidifiers are known, but there are no autonomous devices among them that would ensure the creation of a given humidity in a room with the minimum mass-dimensional dimensions with the possibility of its regulation, including through remote control.

A technical problem is the narrow arsenal of autonomous compact controlled air humidifiers suitable for creating the required humidity in various types of rooms through remote control.

The technical result is the expansion of the range of autonomous compact humidifiers with the ability to remotely control them.

The connector is preferably made in the form of a USB connector for connecting a remote access peripheral module. The circuit board with a USB connector is powered by a power supply. The circuit board with a USB connector is equipped with electrical contacts to enable electrical connection to the control unit.

As a peripheral device for remote access, it is preferable to use Wi-Fi modules known for these purposes for connecting a Wi-Fi receiver-transmitter and controlling the inventive humidifier remotely via a WEB page or a computer program installed on a mobile phone.

When the Wi-Fi module is disconnected, the rubber shutter closes the USB connector, eliminating the possibility of foreign objects and splashing water on the circuit board with a USB connector.

As a converter, the inventive humidifier preferably contains an ultrasonic transducer, which allows to obtain water dust, which is a fine droplet of water.

Figure 4 - shows the appearance of a humidifier and a rubber curtain without a Wi-Fi module;

Figure 5 - schematically shows a control panel with an information display.

The inventive humidifier (Figure 1) is based on the principle of forced evaporation and contains placed in the housing 1 of the reservoir 2 for the aqueous phase, which is filled with water, an ultrasonic transducer 3, which creates a vibration in the aqueous phase in the reservoir 2 and generates a stream of water dust in the inner chamber of vaporization 4, which communicates with the atomizer 5 installed at the outlet of the housing 1, a fan 6 installed in the lower part of the housing and providing for forced movement of the air flow received through There is an air intake hole located in the lower part of the housing, a pallet 7. In the front of the housing 1 there is a control unit 8 containing an electronic board 9 with a programmable microcontroller 10, radio elements 11, a quartz resonator 18, a hygrostat 19 and an information display 12. Electrical connection is provided with electric wires 15 from the power supply 16. On the front side of the housing there is a control panel 13 with windows for the information display 12 and controls 14, made in the form of buttons. In the pallet 7 and on the bottom of the housing 1 there is a light source, which is used as multi-colored LEDs 17. In the lower part of the housing 1, a thermometer 20 and a hygrometer 21 are located in the air intake hole. A socket 28 is made in the end cover of the housing, which is mechanically screwed (not shown) a printed circuit board 29 is fixed, having electrical contacts for electrical communication with the control unit 8 and a USB connector 30 for connecting a WiFi module 31. The USB connector 30 is equipped with an elastic shutter 32 made of rubber.

The inventive device in normal mode operates as follows. Water from the tank 2 for the aqueous phase enters the pan 7, where the ultrasonic transducer 3 by means of high-frequency vibrations of the ultrasonic membrane breaks the water into tiny particles, forming steam. The fan 6 pumps air from the room through the air intake hole into the inner chamber of vaporization 4. Air enriched with water vapor is blown humidified back into the room through a spray gun 5.

Thermometer 20, which is used as a semiconductor element (thermistor), depending on the temperature of the air changes the electrical resistance, based on the readings of which the programmable microcontroller 10 determines the temperature of the incoming air flow from the room. Based on the data transmitted by the thermometer 20 to the programmable microcontroller 10, the latter determines the air temperature in the room, according to a given program calculates the level of optimal air humidity and sends a command to the hygrostat 19.

The hygrometer 21, due to changes in the electric capacity depending on the change in relative humidity in the room, changes its capacity, based on this capacity, the programmable microcontroller 10 determines the current relative humidity in the room and transmits this data to the hygrostat 19. Hygrostat 19 based on the received data on air temperature and relative humidity in the room and the obtained data on the necessary optimal relative humidity controls the intensity of the ultrasonic transducer 3, or pre raschaet it.

Quartz resonator 18 is an element of the integrated circuit of the device that sets the clock frequency of the microcontroller. When voltage is applied to the electrodes, the quartz resonator 18, due to the piezoelectric effect, creates an electrical signal with a given clock frequency, which is the carrier for the microcontroller (carrier clock frequency). A programmable microcontroller 10 based on the carrier clock frequency of the quartz resonator 18 has the ability to determine the real time and on this effect the specified mode lasts 60 minutes. After starting this mode, the programmable microcontroller 10 starts the countdown and displays on the information display 12 the number of minutes remaining until the end of the specified mode (countdown).

As an example, we give an example of setting the settings (Figure 5) of the inventive humidifier and control modes of operation.

To start the humidifier in a given mode, you must turn on the device and set this mode by clicking on the control panel 13 on the corresponding control element 14, made in the form of a set of buttons (Figure 5). By pressing the button 22, the device turns on, and by pressing the button 23, the set mode is turned on. On the information display 12 in the corresponding familiarity 24 displays an indication of the specified operating mode, for example, the "sport" mode. The indication of the evaporation rate is displayed on the information display 12 in familiarity 25. The indicated indication lights up if it is necessary to raise the relative humidity in the room to the set value. Indication of familiarity is carried out automatically by turning on the LEDs 17, which provide lighting, for example, blue light. LEDs 17 indicate the operating mode for active sports and burn until the end of work in a given mode. The duration of the specified operating mode is displayed in the timer 26 of the information display 12, and the temperature is displayed in the temperature familiarity 27 of the information display 12.

Humidifier control in the case of remote location of the consumer (Figure 2 - Figure 4) is carried out from a peripheral device using a home Wi-Fi router, from where the control signal is sent to WiFi module 31. Control from a smartphone or tablet computer running IoS operating systems or Android, is carried out using a GUI application. The Wi-Fi humidifier module 31 establishes a connection to the server using the Internet on which the server part of the application is installed. The mobile application also establishes a connection to the server using the Internet. The server part of the application synchronizes a specific air humidifier with a specific mobile application, based on user accounts.

The printed circuit board 29 with a USB connector 30, in which the Wi-Fi module 31 is installed, interacts electrically with the humidifier control unit 8 through an electric contact group (Figure 3) with an electric drive (not shown). The Wi-Fi signal of module 31 is transmitted to the programmable microcontroller 10 of the electronic board 9. The priority of the signals from the control panel 13 and from the Wi-Fi module 31 is distributed as follows - when a remote and manual signal are sent, the execution command is issued with respect to the signal that acted last. Through the serial port, all the parameters of the humidifier are controlled, readings of the radio elements located on the electronic board 9 and error codes are read. Data is sent from the programmable microcontroller 10 of the electronic board 9 to the server and received from the server via Wi-Fi module 31. At the signal from the server, from the electronic board 9 of the control unit 8 of the air humidifier, new commands are issued to set the remotely set operating modes.

The use of the inventive humidifier expands the range of compact stand-alone devices suitable for control in manual mode and in remote access mode.
