めに、活性炭等の吸着剤の量により吸着容量が決まる。(Prior Art) In order to purify contaminated air containing various malodorous substances generated in the home, deodorizing devices equipped with various deodorizing methods have been considered. Among these, the most commonly used deodorizing method is one in which deodorization is performed by physically adsorbing molecules of odor substances using an adsorbent, typically activated carbon. However, since this method deodorizes by physical adsorption, the adsorption capacity is determined by the amount of adsorbent such as activated carbon.
このため、吸着剤の寿命が比較的短かく、吸着剤の交換
等のメインテナンスを必要とする。Therefore, the life of the adsorbent is relatively short, and maintenance such as replacement of the adsorbent is required.

適宜時期に手動で行うようにしている。For example, as disclosed in Japanese Patent Publication No. 59-12935, an adsorbent and an oxidation catalyst are provided, and the indoor air is purified and circulated, and the adsorbent is heated and regenerated. A method has been proposed in which the odor substances re-released from the adsorbent are decomposed and removed using an oxidation catalyst to extend the life of the adsorbent and reduce its usage. In this conventional method, the heating regeneration of the adsorbent is performed by operating a timer or manually at appropriate times.

ー自身が行わなければならないという好ましくない問題
がある。However, if the heating regeneration of the adsorbent is performed by operating a timer or manually at an appropriate time, it is difficult to correctly determine the period when the adsorption amount of the adsorbent has reached saturation, that is, the time when regeneration is necessary. Furthermore, there is an undesirable problem in that the user must perform the heating operation himself.
このため、ガスセンサを用いて吸着剤からの漏出臭気を
検出し、この検出出力により吸着剤の再生大行を制御す
るようにした方式が考えられている。For this reason, a method has been considered in which a gas sensor is used to detect the odor leaking from the adsorbent, and the output of this detection is used to control the regeneration of the adsorbent.

め、余分な電力消費を招くおそれがある。However, in this method, the sensitivity of the gas sensor is influenced by the circulating air volume during deodorization or the hot air during heating regeneration, and the detected output value changes. For this reason, it is difficult to correctly detect the necessary regeneration timing, and when the regeneration operation is executed, the regeneration operation is continued or repeated more than necessary, which may lead to excessive power consumption.

Because the detected output value changes due to the influence of However, there is a problem in that it may lead to excessive power consumption.

Therefore, when the deodorizing operation is performed for an appropriate period and the effectiveness of the adsorbent decreases, the difference in the atmosphere inside and outside the casing can be accurately detected by the differential output, and the time required for regeneration of the adsorbent can be accurately detected. . Then, the heater is energized based on this detection signal, and the adsorbent is heated and regenerated. When re-emission of odorous substances from the adsorbent stops as the regeneration operation progresses, the end of the regeneration operation is accurately detected in the same manner as described above by the differential output of the differential atmosphere sensor.

ている。The differential atmosphere sensor 10 has a pair of semiconductor odor sensors, an inner sensor and an outer sensor, mounted on both sides of a thin insulating substrate with high thermal conductivity. The structure is such that it can be extracted as a dynamic output. That is, a heater 13 is embedded in a thin insulating substrate (hereinafter also referred to as a heater substrate) 12 having high thermal conductivity. A pair of electrodes 14a and 14b are formed on both sides of the heater substrate 12 so as to face each other, and sensitive parts 15a and 15b made of a semiconductor material are respectively adhered to cover the picture electrodes 14a and 14b. There is. An inner sensor is configured on the sensitive part 15a side, and an outer sensor is configured on the sensitive part 15b side. Mesh filters 16 are placed on both sides of the sensor main body constructed in this manner.

１４ｂの各端子が検出部１１に接続されている。electrodes 14a formed on both sides of the heater substrate 12,

信号が出力されるようになっている。When molecules of an odor substance are adsorbed on the surfaces of the sensing parts 15a, 15b while the sensing parts 15a, 15b are heated to a predetermined temperature by the heater 13, the distance between the electrodes 14a, 14b is determined according to the amount of adsorption. The resistance value of detecting section 1 changes and
1, a difference signal is output that changes according to changes in the resistance values of both sensor sections.

In FIG. 3, the a characteristic line shows the resistance value change characteristic which is the detection signal of the inner sensor, and the b characteristic line shows the resistance value change characteristic which is the detection signal of the outer sensor.

b is heated to a predetermined temperature, and the difference between the inside atmosphere and the outside atmosphere of the casing 1 can be detected.

となる。When the fan 4 is driven during deodorization, indoor air containing odor is taken into the housing 1 through the intake port 2. The odor-containing air taken in is deodorized by physical adsorption of the odorous substances in the air by the adsorbent 6, and the deodorized air is blown into the room from the outlet 3. In this way, indoor air is purified. When the deodorizing operation is performed normally, the concentrations of odorous substances in the inner atmosphere and the outer atmosphere of the casing 1 near where the differential atmosphere sensor 10 is installed are almost constant. Therefore, the detection levels of the inner sensor and the outer sensor in the differential atmosphere sensor 10 are supposed to be approximately the same level. However, since the air volume by the fan 4 during deodorization is set to a larger value than during regeneration, which will be described next, the inner sensor is cooled and its sensitivity changes, causing a difference between the rain detection levels of the inner and outer sensors. tends to occur.

所定値以下となり、脱臭動作が正常に行われていること
が示される。However, since the inner sensor and the outer sensor are formed on both sides of the thin heater substrate 12 having high thermal conductivity, the temperatures of both sensors are almost the same, and the sensitivity changes similarly. Therefore, the absolute value of the detection level between the inner sensor and the outer sensor varies, but the resistance value (difference between a characteristic and b characteristic), which is the differential output, is as shown in Fig. 3 during deodorization.
The value is below the predetermined value, indicating that the deodorizing operation is being performed normally.
適宜期間、脱臭動作が行なわれて吸着剤６の効力が落ち
ると、筺体１の内側雰囲気の臭気物質濃度が増し、差動
出力が所定値以上（第３図中のｄ）となって吸着剤６の
再生に必要な時期が正確に検知される。When the deodorizing operation is performed for an appropriate period and the effectiveness of the adsorbent 6 decreases, the concentration of odorous substances in the atmosphere inside the housing 1 increases, and the differential output exceeds a predetermined value (d in Fig. 3), causing the adsorbent to lose its effectiveness. The timing required for the reproduction of 6 can be accurately detected.
この検知信号を基に、カートリッジヒータ８、９に通電
されて吸着剤６の加熱再生が行われる。Based on this detection signal, the cartridge heaters 8 and 9 are energized to heat and regenerate the adsorbent 6.
再生時は、ファン４による風量は脱臭時よりも低く設定
され、吸着剤から濃縮された臭気物質が再放出される。During regeneration, the air volume by the fan 4 is set lower than during deodorization, and concentrated odorous substances are re-released from the adsorbent.

終了信号を基にカートリッジヒータ８．９の通電を停止
して再生を終了する。This re-released odor substance is decomposed and removed by the thermal decomposition catalyst 7, and is prevented from leaking into the room. In this heating and heating process, the differential atmosphere sensor 10 is heated by the influence of hot air, but as in the case of deodorization described above, the sensitivity of the inner sensor and outer sensor changes in the same way. The difference between the atmosphere inside and outside the casing 1 is appropriately detected. As the deodorizing operation progresses, the differential output gradually decreases as shown during regeneration in Figure 3, and when the re-emission of odorous substances stops,
When the value is below a predetermined value, the end of reproduction is indicated. Based on this regeneration end signal, the cartridge heater 8.9 is de-energized to end the regeneration.
再生の終了後、脱臭装置は稼動が一時休止され、吸着剤
６が冷却されて、再び元の脱臭能力が与えられる。After the regeneration is completed, the operation of the deodorizing device is temporarily suspended, the adsorbent 6 is cooled, and the original deodorizing ability is restored.

An automatic control method may be used in which the cartridge heater 8.9 is turned off, or an appropriate notification means may be operated based on the detection signal, and the energization path of the cartridge heater 8.9 may be manually turned off based on the notification signal. Good too.

。[Effects of the Invention] As explained above, according to the present invention, a detection signal corresponding to the difference between the inside atmosphere and the outside atmosphere of the casing is provided near the outlet through which the gas after deodorization by the adsorbent is blown out. Because we installed a differential atmosphere sensor that outputs a control signal for the regeneration operation of the adsorbent, the sensitivity of the differential atmosphere sensor changes due to the influence of the circulating air volume during deodorization or the hot air during heating regeneration. However, since the differential output is almost unaffected by temperature changes, the difference in atmosphere inside and outside the case can be accurately detected at all times. Therefore, it is possible to accurately detect the time required for regeneration when the effectiveness of the adsorbent has decreased, and the end of the regeneration operation when the re-release of odor substances from the adsorbent has stopped during heating regeneration. This has the advantage that it is possible to appropriately control the odor and to perform an appropriate deodorizing operation at all times without causing odor leakage into the room.
