Description

本考案は、ホコリ量検出装置に関するものであって、特に、使用者が適時に空気洗浄ユニットに対し、交換、或いは、洗浄を実行することができるホコリ量検出装置に関するものである。 The present invention relates to a dust amount detection device, and more particularly, to a dust amount detection device that allows a user to replace or clean an air cleaning unit in a timely manner.

科学技術の発展に伴い、人々は多くの電子装置を開発し、電子装置は多種の発熱素子を有するので、電子装置が作動する時、内部の温度も高くなり、電子装置内部の温度環境が高すぎると、電子装置が故障を生じやすく、正常に作動しなくなる。 With the development of science and technology, people have developed a lot of electronic devices, and electronic devices have various heating elements, so when the electronic device operates, the internal temperature becomes high and the temperature environment inside the electronic device becomes high. If it is too high, the electronic device is prone to failure and does not operate normally.

よって、電子装置の発熱素子により生成される熱エネルギーを快速に散熱させるため、通常は、電子装置内部に散熱装置を内設し、例えば、ファンにより熱対流を増加させて、電子装置が正常な作業環境下で作動できるようにしている。また、ファンの吸風口、或いは、排風口に空気洗浄ユニット、例えば、フィルターを設置し、ファンが回転する時、外部環境の冷たい空気をフィルターから電子装置内部に送入し、ファンが電子装置内部の高温空気を排出して、温度を下げる効果を達成する。 Therefore, in order to quickly dissipate the heat energy generated by the heating element of the electronic device, the electronic device is normally installed by installing a heat dissipation device inside the electronic device, for example, by increasing the heat convection with a fan. It can be operated in the work environment. Also, an air cleaning unit such as a filter is installed at the air intake or exhaust port of the fan, and when the fan rotates, cool air from the outside environment is sent from the filter to the inside of the electronic device. High temperature air is exhausted to achieve the effect of lowering the temperature.

しかし、フィルターは、通常、ホコリを堆積し、フィルター上に累積したホコリが多くなると、フィルターを通過する気流量が減少し、ファンの回転速度が高くなり、電子装置内の熱エネルギーが効果的に排出されなくなる。 However, the filter usually accumulates dust, and if the dust accumulated on the filter increases, the air flow rate passing through the filter decreases, the fan speed increases, and the heat energy in the electronic device is effectively reduced. It will not be discharged.

上述の問題を改善するために、本考案は、空気洗浄ユニットのホコリ量を検出する検出装置を提供する。 In order to improve the above-mentioned problem, the present invention provides a detection device for detecting the dust amount of an air cleaning unit.

本考案のホコリ量検出装置は、空気洗浄ユニットのホコリ累積程度を検出し、ホコリ量検出装置は電子装置内に装着されて、電子装置はホコリ量検出装置が検出した結果に基づいて自主的に使用者に適時の空気洗浄ユニットの交換や洗浄の注意を促し、電子装置の正常な作動を確保する。 The dust amount detection device of the present invention detects the degree of dust accumulation of the air cleaning unit, the dust amount detection device is mounted in the electronic device, and the electronic device is voluntarily based on the result detected by the dust amount detection device. Encourage users to replace and clean the air cleaning unit in a timely manner and ensure the normal operation of the electronic device.

本考案のホコリ量検出装置は、空気洗浄ユニットとファンの間に位置し、空気洗浄ユニットとファンは電子装置内に位置する。ホコリ量検出装置は、環境温度を感知する第一温度センサーと、熱エネルギーを提供する加熱器と、加熱器上に位置し、加熱器の温度を感知する第二温度センサーと、からなる。環境温度と加熱器の温度間の温度差ΔT1と設定される基準温度差ΔT2の比較結果に基づいて、空気洗浄ユニット上に累積したホコリ量程度を判断する。 The dust amount detection device of the present invention is located between the air cleaning unit and the fan, and the air cleaning unit and the fan are located in the electronic device. The dust amount detection device includes a first temperature sensor that senses environmental temperature, a heater that provides thermal energy, and a second temperature sensor that is located on the heater and senses the temperature of the heater. Based on the comparison result of the temperature difference ΔT1 between the ambient temperature and the heater temperature and the set reference temperature difference ΔT2, the degree of dust accumulated on the air cleaning unit is determined.

本考案の電子装置は、制御ユニットと警告ユニットとを有し、制御ユニットは温度差ΔT1と基準温度差ΔT2間の温度差ΔTを計算すると共に、温度差ΔTと警告温度と比較し、温度差ΔTが警告温度より高い時、制御ユニットが警告ユニットに警告信号を発信させて、使用者に、空気洗浄ユニットの交換か洗浄の注意を促す。 The electronic device of the present invention has a control unit and a warning unit, and the control unit calculates a temperature difference ΔT between the temperature difference ΔT1 and the reference temperature difference ΔT2, and compares the temperature difference ΔT with the warning temperature. When ΔT is higher than the warning temperature, the control unit sends a warning signal to the warning unit to prompt the user to replace or clean the air cleaning unit.

本考案のホコリ量検出装置は、空気洗浄ユニットのホコリ累積程度を検出し、使用者に適時の空気洗浄ユニットの交換や洗浄の注意を促し、電子装置の正常な作動を確保する。 The dust amount detection device of the present invention detects the accumulated amount of dust in the air cleaning unit, prompts the user to replace the air cleaning unit in a timely manner, and take care of cleaning, and ensure the normal operation of the electronic device.

本考案のホコリ量検出装置は、電子装置上に応用し、電子装置上の空気洗浄ユニットのホコリ量程度を検出し、使用者に交換か洗浄が必要かどうかを注意させる。電子装置はファン、及び、空気洗浄ユニットを装着する電子装置、例えば、投影機、コンピュータ、空調装置、除湿機、或いは、その他の電子装置である。 The dust amount detection device of the present invention is applied to an electronic device, detects the amount of dust in an air cleaning unit on the electronic device, and makes the user aware of whether replacement or cleaning is necessary.

図1は、本考案の電子装置構造を示す図である。図のように、本考案の電子装置10内に、風道12、ファン14、フィルター等の空気洗浄ユニット16、及び、電子装置の作動を制御し、ファン14を結合して、ファン14の回転速度を制御し、ファン14が回転する時、電子装置10外の気流が空気洗浄ユニット16を経由して電子装置10内に進入する制御ユニット13、及び、制御ユニット13に結合され、データを保存するメモリ15と、からなり、空気洗浄ユニット16は風道12の一端に位置し、ファン14は風道12のもう一端に位置し、且つ、メモリ15は電気的消去可能ROM(EEPROM)である。 FIG. 1 is a view showing an electronic device structure of the present invention. As shown in the figure, the electronic device 10 of the present invention includes an air passage 12, a fan 14, an air cleaning unit 16 such as a filter, and the operation of the electronic device, and the fan 14 is coupled to rotate the fan 14. Controlling the speed, when the fan 14 rotates, the airflow outside the electronic device 10 is coupled to the control unit 13 that enters the electronic device 10 via the air cleaning unit 16 and the control unit 13 to store the data. The air cleaning unit 16 is located at one end of the air passage 12, the fan 14 is located at the other end of the air passage 12, and the memory 15 is an electrically erasable ROM (EEPROM). .

図2で示されるように、ホコリ量検出装置18は電子装置10内に設置されて、空気洗浄ユニット16上に累積したホコリ量程度を検出する。図で示されるように、ホコリ量検出装置18は電子装置10内に位置し、且つ、空気洗浄ユニット16とファン14の間に位置し、二つの温度センサー181、182、及び、熱エネルギーを提供する加熱器183と、からなる。加熱器183は、例えば、セメント抵抗、或いは、熱抵抗で、固定電圧が抵抗両端に施加され、固定温度を有し、且つ、温度センサー181は風道12の一位置上、或いは、電子装置10内の任意の位置に位置し、電子装置10の制御ユニット13に結合され、環境温度T1を感知すると共に、この環境温度T1結果を制御ユニット13に伝送する。加熱器183は風道12のもう一つの位置に位置し、且つ、温度センサー182は加熱器183上に位置すると共に、電子装置10の制御ユニット13に結合されて、加熱器183の温度T2を感知すると共に、加熱器温度T2結果を制御ユニット13に伝送し、その後、制御ユニット13は環境温度T1と加熱器温度T2間の温度差ΔT1を計算し、この温度差ΔT1とメモリ15内に設定された基準温度差ΔT2と比較し、即ち、温度差ΔT1と基準温度差ΔT2間の温度差ΔT(=ΔT1−ΔT2)を計算し、この温度差ΔTに基づいて、空気洗浄ユニット16上に累積したホコリ量程度を判断することができ、温度差ΔTが大きくなる時、空気洗浄ユニット16上のホコリ量が多いことを示す。また、制御ユニット13は環境温度T1、加熱器温度T2、温度差ΔTの温度値データをメモリ15内に保存する。 As shown in FIG. 2, the dust amount detection device 18 is installed in the electronic device 10 and detects the amount of dust accumulated on the air cleaning unit 16. As shown in the figure, the dust amount detection device 18 is located in the electronic device 10 and located between the air cleaning unit 16 and the fan 14, and provides two temperature sensors 181, 182 and thermal energy. And a heater 183. The heater 183 is, for example, a cement resistor or a thermal resistor, and a fixed voltage is applied to both ends of the resistor to have a fixed temperature. The temperature sensor 181 is located at one position of the air passage 12 or the electronic device 10. It is located at any position of the electronic device 10 and is coupled to the control unit 13 of the electronic device 10 to sense the ambient temperature T1 and transmit the ambient temperature T1 result to the control unit 13. The heater 183 is located at another position of the air passage 12, and the temperature sensor 182 is located on the heater 183 and is coupled to the control unit 13 of the electronic device 10 so that the temperature T2 of the heater 183 is determined. In addition to sensing, the heater temperature T2 result is transmitted to the control unit 13, and then the control unit 13 calculates the temperature difference ΔT1 between the ambient temperature T1 and the heater temperature T2, and sets this temperature difference ΔT1 in the memory 15 Is compared with the calculated reference temperature difference ΔT2, that is, a temperature difference ΔT (= ΔT1−ΔT2) between the temperature difference ΔT1 and the reference temperature difference ΔT2 is calculated and accumulated on the air cleaning unit 16 based on the temperature difference ΔT. When the temperature difference ΔT increases, it indicates that the amount of dust on the air cleaning unit 16 is large. Further, the control unit 13 stores the temperature value data of the environmental temperature T1, the heater temperature T2, and the temperature difference ΔT in the memory 15.

基準温度差ΔT2は空気洗浄ユニット16がホコリの被害を受けていない時、温度センサー181により感知された環境温度T1’と温度センサー182が感知した加熱器温度T2’の温度差を基準温度差ΔT2とし、即ち、ΔT2=T2’―T1’で、温度センサー181、182はそれぞれ環境温度T1’、加熱器T2’温度を制御ユニット13に伝送して基準温度差ΔT2を計算すると共に、メモリ15内に保存し、参考比較する。また、空気洗浄ユニット16のホコリが詰まる時、制御ユニット13はファン14の回転を加速するので、大きい風量が加熱器183に吹かれて、加熱器温度T2が下降し、故に、環境温度T1と加熱器温度T2間の温度差ΔT1は大きくなる。また、空気洗浄ユニット16のホコリが大量の時、制御ユニット13はファン14を加速させるが、空気洗浄ユニット16の重大なホコリ詰まりのために、加熱器183への風量が小さく、加熱器温度T2が上昇する。よって、このような状況下で、環境温度T1と加熱器温度T2間の温度差ΔT1も大きくなる。故に、加熱器温度T2は温度上昇、下降にかかわらず、皆、ホコリが空気洗浄ユニット16に累積していることを示し、且つ、環境温度T1と加熱器温度T2の温度差ΔT1と設定された基準温度差ΔT2の差が大きくなるほど、空気洗浄ユニット16上に累積したホコリ量が多く、詰まり程度が高いことを示す。 The reference temperature difference ΔT2 is the difference between the ambient temperature T1 ′ detected by the temperature sensor 181 and the heater temperature T2 ′ detected by the temperature sensor 182 when the air cleaning unit 16 is not damaged by dust. In other words, when ΔT2 = T2′−T1 ′, the temperature sensors 181 and 182 respectively transmit the environmental temperature T1 ′ and the heater T2 ′ temperature to the control unit 13 to calculate the reference temperature difference ΔT2 and in the memory 15 Save for reference comparison. Further, when the dust of the air cleaning unit 16 is clogged, the control unit 13 accelerates the rotation of the fan 14, so that a large amount of air is blown to the heater 183 and the heater temperature T2 is lowered. The temperature difference ΔT1 between the heater temperatures T2 increases. In addition, when the air cleaning unit 16 has a large amount of dust, the control unit 13 accelerates the fan 14, but due to a serious dust blockage of the air cleaning unit 16, the air volume to the heater 183 is small, and the heater temperature T2 Rises. Therefore, under such circumstances, the temperature difference ΔT1 between the environmental temperature T1 and the heater temperature T2 also increases. Therefore, the heater temperature T2 indicates that dust is accumulated in the air cleaning unit 16 regardless of whether the temperature rises or falls, and the temperature difference ΔT1 between the environmental temperature T1 and the heater temperature T2 is set. As the difference in the reference temperature difference ΔT2 increases, the amount of dust accumulated on the air cleaning unit 16 increases and the degree of clogging is higher.

更に、適時に使用者に空気洗浄ユニット16の交換や洗浄の注意を促すために、電子装置10は、更に警告ユニット20を有して、自動的に使用者に注意を促し、図3の電子装置とホコリ量検出装置の回路で示されるように、警告ユニット20は制御ユニット13と結合し、メモリ15内に警告温度が存在して、制御ユニット13に計算後の温度差ΔTと警告温度の比較を提供して比較させ、温度差ΔTが警告温度を超過する時、制御ユニット13は警告ユニット20を起動して、例えば、ランプ信号、音声信号等の警告信号、或いは、OSD信号を発信し、電子装置10のスクリーン(図示しない)により空気洗浄ユニット16の現在のホコリ累積量、詰まり程度の如何を表示する。温度差ΔTが警告温度を大幅に超過する時、制御ユニット13は直接、電子装置を停止して、電子装置10の温度が高くなるのを防止する。 Furthermore, in order to prompt the user to replace the air cleaning unit 16 and to be careful of cleaning in a timely manner, the electronic device 10 further includes a warning unit 20 to automatically alert the user to the electronic device shown in FIG. As shown in the circuit of the device and the dust amount detection device, the warning unit 20 is coupled to the control unit 13, and there is a warning temperature in the memory 15, and the calculated temperature difference ΔT and the warning temperature are calculated in the control unit 13. When the temperature difference ΔT exceeds the warning temperature, the control unit 13 activates the warning unit 20 to send a warning signal such as a lamp signal, an audio signal, or an OSD signal. The screen (not shown) of the electronic device 10 displays the current dust accumulation amount and clogging degree of the air cleaning unit 16. When the temperature difference ΔT greatly exceeds the warning temperature, the control unit 13 directly stops the electronic device to prevent the temperature of the electronic device 10 from increasing.

上述のように、本考案のホコリ量検出装置は、適時、空気洗浄ユニットに対する交換や洗浄をサポートし、電子装置が温度上昇により故障するのを防止し、ファンや空気洗浄ユニットを有する電子装置は本考案のホコリ量検出装置を利用して、ホコリ量の検出を実行できる。 As described above, the dust amount detection device of the present invention supports timely replacement and cleaning of the air cleaning unit, prevents the electronic device from malfunctioning due to temperature rise, and the electronic device having a fan and an air cleaning unit is The dust amount detection apparatus of the present invention can be used to detect the dust amount.
