この発明は洋式トイレ用の衛生洗浄機のベーンポンプに
関するもので、特にベーンポンプの改良に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a vane pump for a sanitary washing machine for a Western-style toilet, and particularly relates to an improvement of the vane pump.

ポンプｌが形成されている。As shown in FIGS. 1 and 2, a conventional vane pump for a sanitary washing machine has a rotor taco equipped with a plurality of vanes 3 which are biased radially outward by springs, and which are connected from a front casing S and a rear casing 6. It is rotatably housed in a casing, one rotation is given by a motor j, and a seal 7 for preventing water leakage is provided between the casing and the motor.
A pump l is formed.

させて、局部の洗浄を行うものである。To explain the action, as shown in Figures 3 and 2,
The sanitary washing machine 1 is installed in a Western-style toilet 9, and the pump 1 pumps up the water in the tank through the filter 1/ in the low tank IO, conveys it to the hot water tank saw, changes the water to hot water, and S! Uchisan water from the water tank is spouted from the nozzle 13 to clean the private parts.
衛生洗浄機に自吸能力のあるベーンポンプを使用すると
、第１図のロータコと、ケーシングＳ、乙との隙間は平
均でθＯｇ鰭程度に管理しなければ所定能力が出ない。If a vane pump with self-priming capability is used in a sanitary washer, the gaps between the rotor tacho and the casings S and B shown in Fig. 1 must be controlled to an average of θOg fins or the specified capacity will not be achieved.
そのためこの隙間にはごみをかみやすい。こ゛みを防ぐ
ためフィルタ／ｌの目を細かくすると、圧力損失が大き
くなって、ポンプｌの能力が落ちてしまう欠点があった
。Therefore, it is easy for dirt to get caught in these gaps. If the mesh of the filter/l is made finer to prevent clogging, there is a drawback that the pressure loss increases and the capacity of the pump l decreases.

浄機のベーンポンプを提供しているものである。This invention was made in view of the above-mentioned drawbacks of the conventional pumps, and provides a vane pump that is less likely to get dirt caught in the gap between the rotor and the casing, and whose performance will not be reduced due to dirt. For this purpose, by providing a number of recesses in the pump rotor to accommodate debris, debris will accumulate in the recesses and become trapped between the rotor and casing, thus reducing pump capacity. We offer vane pumps for sanitary washing machines that do not fall and are resistant to dirt.
以下、図示する実施例について、この発明の詳細な説明

Since the other parts of the vane pump are the same as those of the conventional vane pump shown in FIGS. In the figure, /7 indicates garbage.
次に、この発明の作用について説明する。Next, the operation of this invention will be explained.

え、ノズル／３より湯水を噴出し、洗浄を行う。The operation of the sanitary washing machine is exactly the same as that explained in Figures 3 and q above, and the water in the low tank 10 is sent from the filter // to the mixed water tank 1 using the pump 1, and is turned into hot water. Then, spray hot water from nozzle /3 to clean.

が数倍長くなった。The rotor 1 (surrounded by the pump casing 2 and As the space volume divided by the vanes changes from J・→Dog→Small, water is sucked in from the inlet !a and discharged from the outlet K. Due to this action, water passes through the filter // from the low tank 10. It is sent to the hot water tank /, 2. At this time, the casing s, 6
The smaller the gap between the motor and the rotor/g in the axial direction of the motor, the less water flows out and the greater the pump capacity becomes. However, if the gap is made smaller, it becomes easy for the dirt in the water to get caught between the rotor is and the casing, the dirt accumulates, the rotational speed of the rotor gradually decreases, and the pump eventually stops. However, in this invention, the rotor/S is
6, the dirt 17 is deposited in the recess/6, so the durability against dirt filtration is several times longer than that of the conventional vane pump.
