Description

Humidifier combined with cold and hot water and control method of humidifier operation

The present invention relates to a humidifier.

In particular, the present invention relates to a humidifier coupled to a cold and hot water coupled to a cold and hot water humidifier coupled to the cold and hot water to perform the humidification operation by receiving the water required by the humidifier from the cold and hot water.

As is well-known, homes and offices operate air-conditioning facilities (e.g., air conditioners, fans, boilers, stoves, etc.) to keep the temperature fluctuating according to the season. By stimulating the situation is causing various diseases, including respiratory diseases.

In particular, household appliances (eg, television sets, refrigerators, air conditioners, video cassette recorders, sound equipment, etc.) used in homes and offices are diversified, and as the number thereof increases, the heat generated during the operation of the indoor air is reduced. As the temperature is increased, the humidity value of the indoor space is further lowered.

When the indoor space is dried in this way, the health of people (healthy people) is not only harmed, but also a fatal adverse effect on a weak person such as a child, an elderly person or a patient.

Accordingly, various measures are taken to keep the humidity value constant. Especially in the homes and hospitals where children and the elderly live, the humidity level is kept constant so that the indoor space can be made more comfortable. There are various means, one of which is the humidifier.

The humidifier is a device that can control the humidity of a certain space, which is installed in a confined space such as a home or office, converts water into an atomized state of water vapor or fine particles, and discharges it into the indoor space to change the humidity value of the indoor space. It is to perform the function of adjusting.

Referring to FIG. 1 to FIG. 2, a conventional humidifier operating state for adjusting the humidity of an arbitrary space is provided with a “key” for setting the overall operating environment of the humidifier such as setting a desired humidity value of the space to be humidified. The keypad 12 and the humidity sensor 14 installed to be exposed to the outside of the humidifier to detect the humidity value of the indoor space, and installed inside the humidification tank 130 to flow into the humidification tank 130 A temperature switch 16 for detecting a temperature value of water, and a float switch installed inside the heating bath 120 or the humidification tank 130 and switching (on / off) by water level flowing from the water tank 110. 18 and the microprocessor 10 which controls the heater 140 and the vibrator 150 to maintain a desired humidity value and outputs driving signals to the heater driver 20 and the vibrator driver 22, Under the control of the microprocessor 10 The heater driver 20 and the oscillator driver 22 for selecting an operating mode of the rotor 140 and the vibrator 150 and the heater 140 and the vibrator 150 generated by the microprocessor 10 under the control. Fan motor driver 24 for controlling the operation of the fan motor 160 for supplying air to discharge the atomization (water vapor) to the outside of the humidifier through the discharge port 170, and under the control of the microprocessor 10 And a buzzer driver 26 for driving a buzzer informing about a low water condition, and a light emitting diode driver 28 for lighting a light emitting diode (LED).

3 is a flowchart illustrating an operation state of a conventional general humidifier.

Determining whether the power applied by the power switch input of the keypad 12 is "on" (S301), and if the determined power is not confirmed as "on", it is determined whether the power is again "on" In step S302, when the power is determined to be "on", the humidity sensor 14 detects a current humidity value inputted as a digital signal, and when the current humidity value is checked, the humidification tank 130 has no water. Step S303 of determining whether the float switch 18 confirming whether the state is "on" and if the float switch 18 is "off" because there is water in the humidification tank 130, the keypad 12 Setting the desired humidity value to be humidified and storing it in a memory (S304), and if the desired humidity value is set, it is determined whether the set desired humidity value is greater than the current humidity value detected by the humidity sensor 14. In step S305, and the determined result, the desired humidity value is smaller than the current humidity value. If the desired humidity value is greater than the current humidity value, select the humidification mode (for example, sleep mode, weak mode, medium mode, strong mode, turbo mode, and purge mode) of the keypad 12. Step (S306) of determining whether "is" "on", and if it is determined that the humidification mode selection "key" is "on" step of heating the heater of the heater 140 by the heater driver 20 (S307) And, when the heater is heated, driving the vibrator of the vibrator 150 by the vibrator driver 22 (S308), and driving the fan motor 160 by the fan motor driver 24 when the vibrator is driven. If the humidification tank 130 has no water and the float switch 18 is “on” as a result of the step S309 and the step S302 returned to step S302, the buzzer is driven by the driving unit 26. Driving step (S310), and if the buzzer is driven to check whether the alarm sound is output more than a certain number of times (for example, 10 times) (S311), and the determined result a certain number of times If the number of times (eg 10 times) has not been outputted, the process returns to step S310, and if the output is a predetermined number of times (eg 10 times), the light emitting diode driver 28 turns on the light emitting diodes (S312). Is showing.

Looking at the operation process, the user determines whether the power applied by the power switch input of the keypad 12 is "on" (S301).

If it is determined that the power is not "on" as a result of the determination, the microprocessor 10 is detected by the humidity sensor 14 and input as a digital signal when the power is again determined to be "on". The current humidity value is checked (S302).

That is, when the current humidity value is checked, the microprocessor 10 determines whether the float switch 18 for checking whether the humidification tank 130 is in the water-free state (S303) by checking whether the humidification tank 130 is “on” (H303). If there is water and the float switch 18 is confirmed to be in the " off " state, the desired humidity value to be humidified by the keypad 12 is stored in the internal memory (S304).

When the desired humidity value to be humidified set by the keypad 12 is stored in the internal memory, the microprocessor 10 determines whether the desired humidity value stored in the memory is greater than the current humidity value detected by the humidity sensor 14 and input. If the desired humidity value stored in the memory is less than the present humidity value detected by the humidity sensor 14, the microprocessor 10 detects the humidity sensor 14 and inputs the digital humidity signal as a digital signal. Check (S302) to repeat the above process.

Meanwhile, if the desired humidity value stored in the memory is greater than the current humidity value, the microprocessor 10 determines that the humidification mode (eg, sleep mode, weak mode, medium mode, strong mode, Turbo mode, purge mode) If it is determined whether the selection "key" is "on" (S306) and one of the humidification mode selection "key" (for example, weak mode) is confirmed as "on", the control signal to the heater drive unit 20 By outputting the heater driver 20 heats the heater 140 (S307).

In addition, when the heater is heated, the microprocessor 10 outputs a control signal to the vibrator driver 22 to drive the vibrator 150 by the vibrator driver 22 (S308).

In addition, when the vibrator is driven, the microprocessor 10 outputs a control signal to the fan motor driver 24 to drive the fan motor 160 by the fan motor driver 24 (S309).

That is, the heater 140, the vibrator 150, and the fan motor 160 are sequentially driven.

When the heater 140, the vibrator 150, and the fan motor 160 are sequentially driven, the microprocessor 10 checks a current humidity value detected by the humidity sensor 14 and input as a digital signal (S302). Repeat the steps.

In addition, if it is determined in the step S303 that there is no water in the humidification tank 130 and the float switch 18 is in the "on" state, the microprocessor 10 buzzer outputs a control signal to the driver 26 to buzzer (not shown). After driving (S310) to check whether the alarm sound is output more than a certain number of times (for example, 10 times) (S311).

If the result of the check does not output more than a certain number of times (eg, 10 times), the microprocessor 10 continuously outputs a control signal to the buzzer driver 26 to drive the buzzer (S310) to generate a predetermined number of alarm sounds ( For example, if it is output more than 10 times) (S311) and outputs a predetermined number of times (eg, 10 times) or more, it outputs a control signal to the LED driver 28 so that the LED is driven by the LED driver 28. Turn on (S312) to inform the user that there is no water in the water tank 110 and the humidification tank 130.

In the humidifier as described above, it is necessary to install a water tank to supply water to the humidification tank, so that the price and volume of the humidifier are increased. In addition, the humidifier is heated to sterilize the water supplied to the humidification tank, but the heating temperature is steady. Because it only heats up to a certain temperature (40 ℃) so that it can operate, it has the drawback that it cannot remove all bacteria. That is, since the water supplied to the humidification tank is heated with mild heat, it has a defect that complete sterilization cannot be achieved.

The present invention has been made to solve the above-mentioned drawbacks as described above, by combining a humidifier with a cold water heater coupled to a cold water heater to selectively receive the water heated by the cold and hot water and cooled water to convert to fine particles To provide a humidifier and a method of controlling the operation of the humidifier.

The invention to achieve the above object is to check whether the humidifier is mounted while adjusting the water temperature of the cold water tank and the hot water tank by driving the heater and the cooling system according to the water temperature detected by the temperature sensor installed in the cold water tank and hot water tank. And a second step of checking whether the humidification mode of the humidifier is set to the cold humidification mode while supplying operation power of the humidifier when the humidifier is installed as a result of the first step, and the humidification mode is set to the cold humidification mode. The third step of performing the humidification mode set by key input while supplying cold water to the humidification tank by opening the solenoid valve for cold water, and opening the solenoid valve for hot water to supply hot water to the humidification tank when the humidification mode is set to the on-humidity mode. Characterized in that the fourth step of performing the humidification mode set by the key input.

As shown in FIG. 4, the humidifier main body 204 can be attached to and detached from a side surface of the cold / hot water main body 200 in which the water tank 202 can be seated thereon. That is, when looking at the outside, the coupling grooves 208 and 210 and the fixing groove 206 are formed in the cold / hot water body 200, and the coupling grooves 208 and 210 at one end of the lower end of the humidifier body 204. And a coupler 212 having coupling protrusions 216 and 218 and fixing protrusions 214 coupled to the fixing groove 206.

The humidifier main body 204, which is detachable to one side of the cold / hot water body main body 200, will be described in detail based on the separated perspective view shown in FIG.

The humidifier body 204 may be divided into a lower case 226, an upper case 228, and a lid 238.

The lower case 226 has a bottom surface 244 on which the vibrator 220 is installed on the upper surface, and is placed on the outer side of the bottom surface 244 to form a humidification tank 240, and the upper case 228 is embedded therein. Outer frame 246 and the fixing protrusion 214 protruding from the outer surface of the outer frame 246 and separated / coupled to the fixing groove 206 and the coupling groove 208 (210) of the cold and hot water heater body 200 and Coupling protrusions 216 and 218 and an inlet 242 connected to one end of the fixing protrusion 214 are connected to the hot water pipe 248 of the cold and hot water machine and the cold water pipe 250.

The upper case 228 is sealed in the upper portion of the inner cylinder 234 and the outer cylinder 232 opened downward, the center of the inner cylinder 234 to guide the discharge of fine water particles and the lid 238 is coupled Opening to form a discharge passage 230, one side of the outer cylinder 232 is attached to the upper coupler 224 is coupled to the lower coupler 218 of the lower case 226. Here, the lower end of the outer cylinder 232 and the upper coupler 224 is narrowly formed to be inserted into the outer frame 246 of the lower case 226.

Finally, the lid 238 is narrowly formed so that the lower end is coupled to the discharge passage 230, the discharge port 236 is formed on one side to discharge the fine water particles in a specific direction.

6 and 7, the internal structure of the cold and hot water combiner is coupled to the humidifier, the cold water valve 258 is provided in the lower portion of the cold water container 252 in which the partition plate 259 for dividing hot water and cold water is embedded. The evaporator 254 is wound around the outer circumferential surface of the cold water container 252, and has a cold water solenoid valve SV2 between the cold water container 252 and the inlet 242 of the coupling port 208. The cold water pipe 250 is connected. In addition, a heater 264 is hypothesized on the bottom surface of the hot water tank 262 connected to the cold water tank 252 and the induction pipe 256, and a hot water valve 260 to the outside of the cold / hot water body 200. Is connected, and a hot water pipe having a solenoid valve SV1 for hot water is connected between the upper portion of the cold / hot water body 200 and the inlet 242 of the coupling port 280.

FIG. 8, which is not described in the drawing, is a cooling system employed in a cold / hot water machine, which is configured to cool drinking water inside the cold water container 252 by circulating a refrigerant such as a working fluid, such as Freon, through a cooling cycle, which is a compressor 268 (compressor). , An evaporator 254 connected to the compressor 268 and an absorption pipe 272 to wind the cold water container 252, and a dryer 276 connected to the evaporator 254 and the capillary tube 274. And a heat dissipating condenser 270 adjacent to the dryer 276. According to this configuration, the refrigerant compressed by the high pressure in the compressor 268 is introduced into the evaporator 254 through the absorption pipe 272 and evaporated, wherein the amount of heat consumed as the heat of vaporization is used as the cold water tank 252, that is, the temperature of the drinking water. It leads to degradation. Accordingly, the drinking water can be cooled as much as desired, and the evaporated refrigerant is introduced into the heat dissipating condenser 279 via the dryer 276 through the capillary tube 274. The introduced refrigerant in the gaseous state is discharged to the outside while passing through the heat dissipating condenser 270 to be reduced to the liquid state. The refrigerant in the liquid state flows into the compressor 268 to again cycle the cooling cycle. Drinking water cooled through such a cooling system, in particular, cold water under the cold water container 252 on which the evaporator 254 is wound, ie, below the divider 259, is discharged to the outside by opening and closing the cold water valve 258. . Due to the difference in density, the relatively hot drinking water located above the divider 258 is supplied to the hot water tank 262 through the induction pipe 256. The hot water in the hot water tank 262 is discharged to the outside by a proper amount as the hot water valve 260 is opened and closed. The drinking water introduced into the hot water tank 262 from the cold water tank 252 by the discharged amount is heated by the heater 264 mounted at the bottom of the hot water tank 262. During heating, the heater 264 operates under the control of a control means (microprocessor) that recognizes the temperature value detected and output by the bimetal mounted on the side of the hot water tank 262 so that the temperature value in the hot water tank 262 is appropriate. Maintained within the temperature range it is possible to supply hot water at a constant temperature at all times.

In order to control the operation of the cold water heater combined with the humidifier as shown in FIG. 9, the humidity sensor 278, the heater 264, the cooling system 280, the micro switch 282, the cold water valve SV1, It consists of the valve | bulb for hot water SV2, the vibrator 220, the microprocessor 284, etc.

FIG. 10 is a flowchart illustrating an operation state of a humidifier coupled to a cold / hot water heater having the configuration as described above. The heater 264 according to the water temperature detected by the temperature sensor installed in the cold water tank 252 and the hot water tank 262. And a first step of checking whether the humidifier is mounted while adjusting the water temperature of the cold water tank 252 and the hot water tank 262 by driving the cooling system 280 and the operation of the humidifier when the humidifier is installed as a result of the first step. The second step of checking whether the humidification mode of the humidifier is set to the cold humidification mode while supplying power, and if the humidification mode is set to the cold humidification mode, opens the cold water solenoid valve SV2 to supply the cold water to the humidification tank 240. The third step of performing the humidification mode set by the key input while supplying, and when the humidification mode is set to the warm humidification mode by opening the hot water solenoid valve (SV1) to supply hot water to the humidification tank 240 and set as key input Being The fourth step of performing the humidification mode is shown.

Hereinafter, the operation of the present invention.

First, if the humidifier is not coupled (mounted) to the cold or hot water, and the micro switch 282 remains "off", the microprocessor 284 recognizes that the cold water and hot water are to be supplied using the hot and cold water heater as in the conventional cold and hot water heater. And control the operation for this. At this time, the microprocessor 284 maintains the cold water solenoid valve SV2 and the hot water solenoid valve SV1 in an "off" state.

That is, the drinking water flowing from the water tank 202 seated on the upper portion of the hot water tank 252 rides through the gap formed between the partition plate 259 and the inner surface of the cold water tank 252 and the cold water tank 252. Induction formed at the center of the divider 259 while being cooled by the cooling system 280 including the evaporator 254 and entering the bottom surface (a portion of the evaporator 24 wound around the outer circumferential surface). The tube 256 is supplied to the hot water tank 262 and heated by the heater 264 formed on the bottom surface.

Subsequently, when the cold water valve 258 is opened, the cold water cooled by the cooling system 280 is discharged to the outside through the cold water valve 258, and the drinking water filled in the bucket 202 is again divided with the partition plate 259. It is filled in a gap formed between the inner surface of the hot water tank 252.

When the hot water valve 260 is opened, the hot water heated by the heater 264 is discharged to the outside and the drinking water of the same amount as the discharged hot water is supplied again through the induction pipe 256. Here, since the density difference is formed in the hot water tank 262 by the temperature difference of the water formed around the partition plate 259 of the cold water tank 252, the water filled in the bottom surface of the cold water tank 252 does not flow backwards. The water filled in 202 is supplied through the induction pipe 256.

The internal temperature of the cold water tank 252 and the hot water tank 262 through which the cold water and the hot water are discharged by the opening of the valves 258 and 260 is a microprocessor that receives a temperature value detected by a temperature sensor (not shown). The cooling system 280 including the evaporator 254 is operated by the control of 284 to adjust the temperature value of the cold water tank 252 to a constant temperature, and the operation of the bimetal attached to one side of the hot water tank 262. As the power supplied to the heater 264 is supplied / blocked, the internal temperature of the hot water tank 262 may also maintain a constant temperature.

When the humidifier is mounted on one side of the cold / hot water machine, the engaging protrusions 216 and 218 and the fixing protrusion of the humidifier body 204 in the coupling grooves 208 and 210 and the fixing groove 206 formed in the cold / hot water body 200. 214 is coupled to the inlet 242 is in close contact with the connection of the cold water pipe 250 and the hot water pipe 248 and at the same time the microprocessor 282 is operated so that the humidifier body 204 is a cold and hot water body ( It tells the microprocessor 284 that it is mounted on the 200.

Then, the microprocessor 284 determines whether the operation mode of the humidifier is set to the cold humidification mode or the warm humidification mode by the operation of the keypad (not shown), and the solenoid valve SV2 or the solenoid valve SV for hot water. ). Accordingly, the cold water filled in the cold water container 252 or the hot water filled in the hot water container 262 is selectively supplied to the humidification tank 240 of the humidifier body 204 through the pipes 248 and 250. At this time, since the hot water supplied from the hot water tank 262 is supplied via the hot water pipe 248 wound on the outer circumferential surface of the cold water tank 252, the vibrator (as in the conventional humidifier formed in the humidification tank 240) ( 220 is maintained at a temperature capable of performing an ideal operation.

When cold water or hot water is supplied to the humidification tank 240 through the path as described above, the humidifier performs a humidification mode set by manipulation of a keypad not shown.

That is, by setting the humidification mode (turbo mode, strong mode, medium mode, weak mode, sleep mode, etc.) of the humidifier by operating the keypad, the vibrator 220 is operated to finely control the cold water or hot water supplied from the cold / hot water machine. By converting into water particles and discharging to the outside through the discharge passage 230 and the discharge port 236, it is possible to cool or warm humidification.

Looking at the operation of the humidifier coupled to the cold and hot water as described above with reference to Figure 10, the microprocessor 284 is a bimetal installed in the hot water tank 262 and the temperature sensor installed in the cold water tank 252, as in the conventional cold and hot water heater. Normal operation of cooling or heating drinking water filled in the cold water tank 252 and the hot water tank 262 by operating the cooling system 280 including the heater 264 and the evaporator 254 according to the detected temperature value. While controlling (S1) it is determined whether the micro switch 280 is switched to the "on" state by the installation of the humidifier (S2).

If it is determined that the micro switch 280 is switched to the "on" state (which means that the humidifier is coupled to the cold and hot water heater), is the humidification mode of the humidifier set to the cold humidification mode while supplying operating power to the humidifier (S3)? Confirm (S4).

When the cold humidification mode for cold humidifying a specific space is set, the cold water solenoid valve SV2 is opened (S5) so that cold water is supplied to the humidification tank 240 of the humidifier, so that the cold water filled in the cold water container 252 is humidified. While supplied to the tank 240 is converted into fine water particles by the vibrator 220 is discharged to the outside.

However, when the cold humidification mode is set to warm and humidify a specific space, the hot water solenoid valve (SV1) is opened so that cold water is supplied to the humidification tank 240 of the humidifier. While supplied to 240, the vibrator 220 is converted into fine water particles and discharged to the outside.

Of course, the humidification operation as described above is to adjust the humidification amount by adjusting the operation intensity of the vibrator 220 by the humidification mode (turbo mode, strong mode, medium mode, weak mode, etc.) set by the operation of the keypad.

Therefore, by converting the cold water and / or hot water supplied from the cold and hot water machine into fine water particles and discharging them to the outside, cold or hot humidification can be performed without installing a water tank in the humidifier.

As described above, the present invention allows the humidifier to be detached to one side of the cold / hot water machine, and performs only the function of the cold / hot water machine when the humidifier is not installed, and performs the function of the cold / hot water machine when the humidifier is installed, and is operated by the operation of the keypad. It is possible to receive water without installing a water tank in a humidifier by selectively receiving cold water and hot water supplied from a cold / hot water heater according to a cold humidification or a warm humidification mode and converting them into fine water particles and discharging them to the outside. Depending on the water, there is an effect that can selectively perform cold and warm humidification.

In particular, by cooling the water heated to a high temperature in the cold and hot water machine to convert the fine water particles to be discharged to the outside can be more hygienic sterilization of the water supplied to the humidification tank.
