Description
本発明は、例えば、流体処理装置における消耗部品の交換時期を使用者に通知するための通知装置及び流体処理装置に関する。
The present invention relates to, for example, a notification device and a fluid treatment device for notifying the user of the replacement time of consumable parts in the fluid treatment device.
従来、水道水を浄化させるための水処理装置が知られている(特許文献1参照)。この水処理装置は、水道水から不純物を除去するための浄化剤を有する。
Conventionally, a water treatment device for purifying tap water is known (see Patent Document 1). This water treatment device has a purifying agent for removing impurities from tap water.
このような浄化剤は、消耗部品であり、使用とともに汚れる。このため、水処理装置の性能を所望の状態に維持するために、消耗部品は、所定の期間使用された後、交換される。
Such a purifying agent is a consumable part and gets dirty with use. Therefore, in order to maintain the performance of the water treatment apparatus in a desired state, the consumable parts are replaced after being used for a predetermined period of time.
このために、上述の水処理装置は、浄化剤の交換時期を使用者に通知するための手段を有する。具体的には、この水処理装置は、水処理装置に流入する水道水の流量を一定にするための定流量弁と、この定流量弁に流入する水道水の圧力を検知する圧力スイッチを有する。
For this purpose, the above-mentioned water treatment device has a means for notifying the user when to replace the purifying agent. Specifically, this water treatment device has a constant flow valve for making the flow rate of tap water flowing into the water treatment device constant, and a pressure switch for detecting the pressure of tap water flowing into the constant flow valve. ..
そして、上述の水処理装置は、圧力スイッチにより定流量弁に流入する水道水の圧力が所定値以上である時間を検知して、検知した時間に基づいて、使用者が浄化剤の交換時期を判断するための情報を通知する。
Then, the above-mentioned water treatment device detects the time when the pressure of tap water flowing into the constant flow valve is equal to or higher than a predetermined value by the pressure switch, and the user sets the replacement time of the purifying agent based on the detected time. Notify information to make a decision.
ところで、上述のような特許文献1に開示された水処理装置の場合、定流量弁に流入する水道水の圧力を検出するための圧力センサを有している。このような圧力センサは、高価であり、交換時期を通知するための手段(通知装置)、延いては水処理装置のコストが嵩んでしまう可能性がある。
By the way, the water treatment apparatus disclosed in Patent Document 1 as described above has a pressure sensor for detecting the pressure of tap water flowing into the constant flow valve. Such a pressure sensor is expensive, and there is a possibility that the cost of the means (notification device) for notifying the replacement time, and thus the water treatment device, will increase.
本発明の目的は、使用者に、水処理装置に組み込まれた消耗部品の交換時期を通知することができる通知装置及び流体処理装置を低コストで提供することである。

次に、通知装置2の使用方法について説明する。先ず、使用者は、図7Aに示すような状態で、交換通知部4を設定する。図7Aに示す状態で、交換通知部4は、判定部6よりも最終ギヤ30fの回転方向(図7Aに矢印A2で示す方向)における前側に位置している。図7Aに示す状態を、通知装置2の初期状態(以下、単に「初期状態」と称する。)と称する。 (How to use the notification device)
Next, how to use the
尚、図示は省略するが、通知装置2は、通知装置2の状態を初期状態に設定する手段(以下、「初期化手段」と称する。)を備えていてもよい。初期化手段は、使用者の操作に基づいて、通知装置2の状態を初期状態に設定する。使用者は、古いフィルタ12を新しいフィルタ12に交換した後、初期化手段を操作することにより、通知装置2の状態を初期状態に設定する。その後、通知装置2の使用が開示される。
Although not shown, the notification device 2 may include means for setting the state of the notification device 2 to the initial state (hereinafter, referred to as "initialization means"). The initialization means sets the state of the notification device 2 to the initial state based on the operation of the user. After replacing the old filter 12 with the new filter 12, the user sets the state of the notification device 2 to the initial state by operating the initialization means. The use of the notification device 2 is then disclosed.
使用者が水栓14を開くと、水道管13から水栓14に向けて水が流れる。この水は、フィルタ12により処理されて、水栓14から流出する。この際、通知装置2を通過した水の流量に応じて、羽根車23が回転する。羽根車23の回転は、減速機3により減速されて、減速機3の最終ギヤ30fに伝達される。そして、最終ギヤ30fとともに、最終ギヤ30fに設けられた交換通知部4及び交換予告部5が回転する。
When the user opens the faucet 14, water flows from the water pipe 13 toward the faucet 14. This water is treated by the filter 12 and flows out of the faucet 14. At this time, the impeller 23 rotates according to the flow rate of the water that has passed through the notification device 2. The rotation of the impeller 23 is decelerated by the speed reducer 3 and transmitted to the final gear 30f of the speed reducer 3. Then, together with the final gear 30f, the exchange notification unit 4 and the exchange notice unit 5 provided on the final gear 30f rotate.
通知装置2を通過した水の流量が所定量に達すると、図7Bに示すように、交換予告部5と判定部6とが上下方向に一致する。換言すれば、交換予告部5は、最終ギヤ30fとともに回転し、フィルタ12の交換時期よりも所定時間前に、判定部6と上下方向に重なる。上下方向は、第一方向の一例に該当する。
When the flow rate of water that has passed through the notification device 2 reaches a predetermined amount, as shown in FIG. 7B, the replacement notice unit 5 and the determination unit 6 coincide with each other in the vertical direction. In other words, the replacement advance notice unit 5 rotates together with the final gear 30f and overlaps the determination unit 6 in the vertical direction before the replacement time of the filter 12 by a predetermined time. The vertical direction corresponds to an example of the first direction.
この状態で、使用者は、判定部6を介して、交換予告部5を視認できる。この結果、使用者は、フィルタ12の交換時期が近付いていることを認識できる。図7Bに示す状態を、通知装置2の交換予告状態(以下、単に「交換予告状態」と称する。)と称する。
In this state, the user can visually recognize the exchange notice unit 5 via the determination unit 6. As a result, the user can recognize that the time to replace the filter 12 is approaching. The state shown in FIG. 7B is referred to as a replacement notice state of the notification device 2 (hereinafter, simply referred to as “replacement notice state”).
図7Bに示す交換予告状態から更に、水が通知装置2を通過すると、図7Cに示すように、交換通知部4と判定部6とが上下方向に一致する。この状態で、使用者は、判定部6(スリット61)を介して、交換通知部4を視認できる。この結果、使用者は、フィルタ12の交換時期が到来したことを認識できる。
When water passes through the notification device 2 from the exchange notice state shown in FIG. 7B, the exchange notification unit 4 and the determination unit 6 coincide with each other in the vertical direction as shown in FIG. 7C. In this state, the user can visually recognize the exchange notification unit 4 via the determination unit 6 (slit 61). As a result, the user can recognize that it is time to replace the filter 12.
尚、図7Dは、既述の判定部の変形例1を備えた水処理装置に関して、図7Cに相当する図である。図7Dに示す構造の場合、図7Bに示す交換予告状態から更に、水が通知装置2を通過すると、交換通知部4と、判定部6Bのスリット61及び判定マーク62aとが上下方向に一致する。
Note that FIG. 7D is a diagram corresponding to FIG. 7C with respect to the water treatment apparatus provided with the above-described modification unit 1 of the determination unit. In the case of the structure shown in FIG. 7D, when water passes through the notification device 2 from the exchange notice state shown in FIG. 7B, the exchange notification unit 4 and the slit 61 and the determination mark 62a of the determination unit 6B coincide with each other in the vertical direction. ..
この状態で、使用者は、スリット61を介して、交換通知部4を視認しつつ、交換通知部4と判定マーク62aとの重なりを視認できる。このため、使用者は、フィルタ12の交換時期が到来したことを、より容易に認識できる。
In this state, the user can visually recognize the overlap between the exchange notification unit 4 and the determination mark 62a while visually recognizing the exchange notification unit 4 through the slit 61. Therefore, the user can more easily recognize that it is time to replace the filter 12.
又、図7Eは、既述の判定部の変形例2を備えた水処理装置に関して、図7Cに相当する図である。図7Eに示す構造についても、図7Dに示す構造と同様に、使用者は、フィルタ12の交換時期が到来したことを、より容易に認識できる。
Further, FIG. 7E is a diagram corresponding to FIG. 7C with respect to the water treatment apparatus provided with the above-described modification unit 2 of the determination unit. As for the structure shown in FIG. 7E, as in the structure shown in FIG. 7D, the user can more easily recognize that it is time to replace the filter 12.
