Problems solved by technology

[0005] However, since the water intake 105 is open towards the external space, the drinking water remaining in passages such as the outlet pipe 103 contacts with the air in the external space at the water intake 105, and therefore, it is not an unpleasant method from a hygienic point of view. Satisfied state
Especially when the user does not perform the water intake operation so frequently and does not perform the water intake operation for a long time, during this period, the remaining drinking water remains in the state of contacting the air at the water intake port 105, so it is not ideal.

no. 1 approach

[0035] In the drinking water supply device having the above overall structure, such as Figure 4 As shown, a curved portion 282 is formed in the vicinity of the water intake 281 in the water intake outlet pipe 28 constituting a passage from the cold water intake valve 27 as an on-off valve to the water intake 281 . The curved portion 282 is formed so as to be curved with a corner edge 283 . That is, the curved portion 282 is not curved smoothly, but is formed such that the inclination or gradient of the inner surface through which drinking water flows changes sharply with the corner edge 283 as the boundary. Furthermore, the passage inner wall surface 284 formed on the upstream side of the corner edge 283 across the corner edge 283 becomes an upward slope toward the water intake valve 27 . The water intake outlet pipe 28 constitutes a water intake outlet passage formed of pipes.

no. 2 approach

[0043] Image 6 The water intake outlet pipe 28a in the drinking water supply device of the second embodiment is shown. This second embodiment differs from the first embodiment only in that the hole 289 for sucking air is formed on the water intake outlet pipe 28a, and is completely the same as the first embodiment in other respects, and has the same structure and structure as the first embodiment. Effect. Therefore, in the following description, differences will be mainly described, and the same reference numerals will be assigned to the same configurations, and repeated detailed descriptions will be omitted.

[0044] In the water intake pipe 28a of the second embodiment, one or two or more holes for sucking air are penetratingly formed on the channel inner wall surface 288 at a position near the downstream side of the corner edge 283 at the innermost position of the bent portion 282. 289. The hole size of the hole 289 is set to such a small size that water hardly passes t...

Embodiment approach

[0051] In addition, the present invention is not limited to the above-described embodiments, but includes other various embodiments. That is, as an object to which the present invention is applied, even figure 1 The present invention can also be applied to structures other than those illustrated. For example, as an ultraviolet lamp for sterilization, the structure illustrated is one used as an ultraviolet lamp 29a linked with water intake, and one used as an ultraviolet lamp 29b for regular lighting, but it is not limited to this, and many can also be used as Most of the ultraviolet lamps linked to water intake are only used as ultraviolet lamps for periodic lighting. In addition, although the structure having the hot water tank 5 in addition to the cold water tank 2 has been described as an example, the hot water tank 5 can be omitted to constitute a drinking water supply device that can only take cold water from the cold water tank 2 . Furthermore, as long as it is a drin...

Abstract

The invention provides a beverage water supply device, which can prevent the beverage water from remaining in a pathway from a water intaking valve to a water intake of a downstream side during a period from a switching off state of the water intaking valve when the water intake is completed to a switching on state of an opening and closing valve due to the next operation. A water intaking outlet pipe (28) communicated with a valve chamber (272) of a cold water intaking valve (27) extends to a water intake (281). On the water intaking outlet pipe (28), a tilted pathway part (286) intersects with an outlet pathway part (287), and a bending part (282) which bends with an angle edge (283) being the dividing line. A pathway inner wall face (284) of the tilted pathway part (286) at an upstream side is formed in an uphill shape, and a pathway inner wall face (288) of an outlet pathway part (287) at the downstream side hangs down. A water flow flowing down along the pathway inner wall face (284) is peeled away from the pathway inner wall face (288) while passing over the angle edge (283). In this case, an eddy current with air is formed at the back of the water flow.

Description

technical field [0001] The present invention relates to a drinking water supply device which is provided with a water intake valve on a water intake pipe extending from a tank or the like, and supplies drinking water stored in the tank or the like by opening and closing the water intake valve. In particular, the present invention relates to a technique capable of maintaining a hygienic condition in a passage from a water intake valve to a water intake well during a non-supply period in which drinking water is not supplied. Background technique [0002] In the past, for example, in the field of water purifiers, such a scheme has been proposed for water purifiers in which the outlet water pipe of the purified water is configured to extend horizontally from the top surface of the water purifier housing and then hang down: The water flow introduced into the water purification outlet of the outlet water pipe generates foam, and the foam is mixed in the water to soften the flow of...
