Abstract

To provide a humidifier capable of sterilizing properly in accordance with the generating amount of chlorine by an electrode. When a user pushes an operation switch, a CPU 11 makes the energization of the electrode 4 (S1) off. When a timer has counted the elapse of a time T1 (S2), the electrode is energized by a voltage supplying source 16 and a current supplying source 17 (S3), and the values of a voltage and a current between respective electrodes at that time are detected by a voltage detecting sensor and a current detecting sensor (S4). The CPU 11 determines the energizing time T1 and the non-energizing time T2 of the electrode 4 in accordance with the detected values based on the correlation table of the values of current, the generating amount of chlorine and the energizing time of the electrode 4 which are stored in an RAM12.

The specific embodiment

Below, according to Fig. 1 to Fig. 5 embodiments of the invention are described.In Fig. 1, the 1st, have the feed-tank of the damping device of prism-shaped framework, the 2nd, be subjected to the water tank by what path 3 will carry out water from the water of this feed-tank 1.

Then, configuration electrode 4 described later in described path 3, and also can water in this path 3, be a part that enlarges tank so can be understood as, in addition, also can be disposed at described being subjected in the water tank 2.Have again, not shown buoy is set in being subjected to water tank 2, be subjected to water in the water tank 2 to be in predetermined water level when following, make not shown switch work, shut down forcibly described.

In addition, be subjected to dispose in the water tank 2 honey comb like humidification with water-absorbing body 5 described, its end (part) is immersed in the water, this humidification is drawn into top by capillarity with the water in this tank 2 with water-absorbing body 5.This humidification for example is made of the nonwoven fabric of making such as tacryl or polyester fiber with water-absorbing body 5.

And, have by blowing out of on the body of damping device, offering, by blowing out with pressure fan 6 that fan and fan electromotor 15 are formed the described humidification structure of the water vapour of water-absorbing body 5 gasifications to indoor supply with opening (not shown).

It is that Ti (titanium), top layer are the two plate electrode plates that Ir (iridium), Ta (tantalum), Pt (platinum) constitute that described electrode 4 for example has body, electrical current is 40 milliamperes, produce the free residual cl concn (for example 1ppm) of regulation, can obtain degerming, anti-fouling effect (bacteria-eliminating efficacy).

Below, the controlling party block diagram of key diagram 2.The 10th, the microcomputer of this damping device of centralized Control (hereinafter referred to as ' microcomputer '), there are the CPU11 as control device, the RAM (random access memory) 12 of store various kinds of data, stored program ROM (read-only storage) 13 and timer 14 etc. in portion within it.

Described microcomputer 10 is carried out by described electrode 4 and is carried out the order of degerming and carry out blowing out with the order of the fan electromotor 15 of pressure fan 6 etc. to described.To the order of described electrode 4 controlling by the time to electrode 4 energisings from the magnitude of voltage of voltage supply source 16 with from the current value in electric current supply source 17.

Carry out such control, when switching in the water of described electrode 4 in described path 3, water is 4H at anode ⁺+ 4e ^-+ (4OH ^-) become 2H ₂+ (4OH ^-), be 2H at negative electrode ₂O becomes 4H ⁺+ O ₂+ 4e ^-, the chlorine (being added on the chlorine in the running water in advance) that contains in water simultaneously is 2Cl at anode ^-Become Cl ₂+ 2e ^-, and this Cl ₂(chlorine) is soluble in water, and then Cl ₂+ H ₂O becomes HClO+HCl.

Therefore, by energising in electrode 4, produce the big HClO (hypochlorous acid) of sterilizing power.

But, described electrode 4 is switched on all the time, the electric power that not only increases consumption, and influence life-span of this electrode 4.Therefore, as shown in Figure 3, make electrode 4 energising by certain time interval, simultaneously in order to improve durability, the cycle carries out polarity and switches in accordance with regulations to the energising of electrode 4.This polarity switch be used to prevent all the time folk prescription when energising because of adhere to precipitate (Ca at cathode side ²⁺, Mg ²⁺Deng) running efficiency that causes descends.

Have, the no power time of described electrode 4 is T1 again, the switching time (positive polarity is time T 3, and negative polarity is a time T 4) among the conduction time T2, is that T3 and T4 are essentially the equal time.But also can make initial T2 conduction time is positive polarity, and be negative polarity the conduction time behind the no power.

According to above structure, the operation based on Fig. 4 is described.At first water (running water) is joined feed-tank 1 and be assembled on the damping device body (not shown), water supplies to through path 3 by its valve from feed-tank 1 and is subjected to water tank 2, and described humidification water-absorbing body 5 aspirates this equably and is subjected to water in the water tank 2.

Then, when the user pushed the running switch of operating portion of damping device, following control was handled in the degerming that electrode 4 carries out.At first, the CPU11 of microcomputer 10 makes electrode 4 no powers (S1), behind 14 timing elapsed time of the timer T1 (S2), make electrode 4 energisings (S3) by voltage supply source 16 and electric current supply source 17, detect each interelectrode magnitude of voltage and current value (S4) at this moment with voltage detecting sensor and current detection sensor (all not shown).

According to this detected value, grasp the state (chlorine generating capacity, cl concn) of humidification water, decision is to the T1 and no power time T 2 (S5) conduction time of electrode 4.Promptly, as shown in Figure 5, according to applying the current value (A, ampere) stored among the RAM12 under fixed voltage (24 volts) situation, chlorine generating capacity between each electrode and to the correlation table of conduction time of electrode 4, the CPU11 decision is to the T1 and no power time T 2 conduction time of electrode 4.This correlation table also can be divided into the correlation table of current value (A, ampere) and chlorine generating capacity and chlorine generating capacity and to the correlation table of conduction time of electrode 4.Conduction time, T1 was minute to be that unit changes, specifically, and for example, if current value is 0.1 ampere, then the chlorine generating capacity is 0.1ppm, and chlorine ion concentration is rare, T1 lengthening conduction time to electrode 4, no power time T 2 shortens simultaneously, on the contrary, if current value increases to 0.5 ampere, then the chlorine generating capacity is 1.4ppm, chlorine ion concentration is dense, to T1 shortening conduction time of electrode 4, no power time T 2 is increased set simultaneously.Have, chlorine ion concentration is the value of inferring according to the chlorine generating capacity, but also can decide according to the correlation table of current value and chlorine ion concentration again.

And, above example reaches correlation table to the conduction time of electrode 4 according to current value (A, ampere), chlorine generating capacity and decides T1 and no power time T 2 conduction time to electrode 4, but also can decide according to not shown detection magnitude of voltage, chlorine generating capacity with to the correlation table of conduction time of electrode 4.

Then, CPU11 judges whether polarity is positive polarity (S6), if positive polarity, then need to make polarity keep positive polarity (S9), and need elapsed time T2 (S13) through with the binary time T 3 of T2 conduction time of above-mentioned decision (S7), turn back to once more and judge whether polarity is the step (S6) of positive polarity, but after above-mentioned binary time T 3 (S7), polarity is negative polarity (S10), keeps this negative pole energising (S8, S12) before elapsed time T4.

Then,, make electrode 4 no power (S1,2) before elapsed time T1, as mentioned above, electrode 4 is controlled, so that carry out positive pole energising and negative pole is switched on through conduction time of above-mentioned decision behind the T2 (S13).

As described above, carry out control repeatedly, but wet practice is following carries out to indoor adding to the no power of electrode 4 and energising (anodal energising and negative pole are switched on).That is, humidification is subjected to water in the water tank 2 with water-absorbing body 5 suction, will supply with originally external indoor of damping device with the air of water vapour the mixings humidification of these water-absorbing body 5 gasifications by blowing out with pressure fan 6.

Have again, by described electrode 4 is switched on, at anode, 2Cl ^-Become Cl ₂+ 2e ^-, and this Cl ₂(chlorine) is soluble in water, so Cl ₂+ H ₂O becomes HClO+HCl.Therefore, produce the big HClO (hypochlorous acid) of sterilizing power.Therefore, can prevent the breeding of other mushrooms such as Legionella, coliform, not to indoor this Legionella etc. of emitting.

Embodiments of the invention more than have been described, but according to the above description, those skilled in the art can form various replacement examples, revise or be out of shape, in the scope that does not break away from spirit of the present invention, comprise above-mentioned various replacement example, revise or distortion.

As mentioned above, the present invention can provide the damping device that is carried out the suitable degerming corresponding with the chlorine generating capacity by electrode.
