  By the way, in water purifiers equipped with an electric pump, drinking water is instantaneously cooled by a built-in rapid cooling device or rapid heating device whenever drinking water is required or when a predetermined amount is consumed. There are types that heat or use or store.

  This type of water purifier is characterized by relatively low power consumption and high energy savings, and is expected to spread.

  On the other hand, it is necessary to continuously feed drinking water to the rapid cooling device or the rapid heating device every time instantaneous cooling and heating are performed, and it is desired to mount an efficient pump. Moreover, since it is often used in ordinary households, the silence of the pump itself is also required.

  However, the gear type or reciprocating type (diaphragm type: a type that pumps up and down the diaphragm through the crank of the motor) used in conventional water purifiers, etc., is not efficient and has an operating sound. There is a difficulty in that is large (for example, 60 dB or more).

  An object of this invention is to provide the pump for water purifiers which can supply drinking water efficiently and can improve silence.

  In order to solve the above-mentioned problem, the water purifier pump according to claim 1 is a disk-shaped turbine in which a plurality of action grooves for generating a vortex flow are formed in a radial direction, a casing for housing the turbine, and the turbine A vortex generating passage formed in the casing so as to accommodate a region where the working groove is formed, a suction passage for introducing drinking water into the vortex generating passage, the suction passage, and the turbine A discharge passage for feeding drinking water from the vortex generation passage, a partition wall separating the vortex generation passage between the suction passage and the discharge passage, It is comprised from the electric motor which rotates a turbine in a predetermined direction, It is characterized by the above-mentioned.

  The water purifier pump according to claim 2 is characterized in that at least one of the turbine and the casing is formed of a predetermined resin.

  The water purifier pump according to claim 3 is characterized in that a filter for filtering the drinking water is provided in at least one of the suction passage and the discharge passage.

  According to the present invention, the following effects can be obtained.

  That is, according to the water purifier pump according to claim 1, the drinking water is passed through each working groove by rotating a disk-shaped turbine in which a plurality of working grooves that generate vortex flow are formed in the radial direction. A pumping action is generated by causing a turbulent flow while rotating, and is pumped from the suction passage to the discharge passage. Since the efficiency increases in proportion to the rotational speed of the turbine, the higher the rotational speed, the higher the efficiency, and the smaller and higher pressure can be obtained. Further, since the rotating system is only an electric motor, the driving sound is quiet and the quietness can be enhanced, and the life can be extended.

  According to the water purifier pump of claim 2, since at least one of the turbine and the casing is formed of a predetermined resin, in a large pump, the turbine or the like is formed of a metal such as stainless steel in order to ensure strength and the like. Cost reduction and size reduction can be achieved as compared with this.

  In addition, it is possible to use polycarbonate etc. as predetermined resin.

  According to the water purifier pump according to claim 3, since a filter for filtering drinking water is provided in at least one of the suction passage and the discharge passage, it is possible to provide safer and more clean drinking water. it can.

  Hereinafter, the best mode for carrying out the present invention will be described more specifically with reference to the drawings. Here, in the accompanying drawings, the same reference numerals are given to the same members, and duplicate descriptions are omitted. In addition, since description here is the best form by which this invention is implemented, this invention is not limited to the said form.

  (First embodiment)

  With reference to FIGS. 1-4, the water purifier pump P1 which concerns on 1st Embodiment about this invention is demonstrated.

  FIG. 1 is a perspective view showing a configuration of a water purifier pump P1 according to the first embodiment of the present invention.

  As shown in FIG. 1, a water purifier pump P <b> 1 includes an electric motor 10 that can be driven by direct current or alternating current and whose rotation speed can be changed, a casing 12 that houses a turbine T attached to a rotating shaft 11 of the electric motor 10, and a mechanical A seal 13, an O-ring 14 formed of silicone rubber or the like that prevents leakage of drinking water, and a lid member 15 are included.

  The casing 12 includes a suction passage 12a and a discharge passage 12b.

  Reference numeral 12d denotes a casing-side mechanical seal.

  Although not particularly limited, at least one of the casing 12 and the turbine T can be formed of a resin such as polycarbonate.

  This makes it possible to form a resin pump, which is impossible with a large pump, and to reduce costs and reduce size and weight.

  Next, the configuration of the turbine T will be described with reference to FIG.

  In the turbine T, a large number of radial blades 100 are erected along the circumference of the disk-shaped turbine main body 50, and a plurality of working grooves 101 that generate vortex flows are formed between the blades 100.

  Although not particularly limited, the turbine T can have a diameter of about 4 cm, for example.
