Description

  The present invention relates to a hot and cold water mixing device including a temperature control function unit.

  Conventionally, a hot and cold water mixing device including a temperature control function unit is known. The operation of the temperature control function unit is generally performed by rotating the temperature control handle.

  Generally, in a hot and cold water mixing device, a safety button is provided on a temperature control handle in order to prevent undesirably high temperature hot water from being discharged (there is a risk of burns). The safety button is a button that is operated when high-temperature hot water is discharged, and the temperature adjustment handle cannot be rotated to the high temperature side unless the safety button is pressed.

  For example, a locking portion is provided on the temperature control handle side, a locked portion is provided on the temperature control function portion side, and the locking portion and the locked portion are arranged at a desired rotation angle of the temperature control handle. The relative positions of the locking portion and the locked portion are adjusted in advance so as to cooperate and restrict further rotation of the temperature control handle. In addition, as described above, the configuration is such that only when the safety button is operated, the locking portion of the temperature control handle is retracted from the cooperative position with the locked portion of the temperature control function portion. Desirably, hot water can be prevented from being discharged.

  Here, the position of the locked portion is determined so that the rotation range of the temperature control handle can be adjusted appropriately according to the region where the hot-and-water mixing faucet device is installed (for example, whether it is a cold region). It is preferable that adjustment is possible. Therefore, a configuration is adopted in which the rotation angle regulating member having the locked portion is a separate component from the temperature control function unit, and the rotation angle regulation member is provided movably with respect to the temperature control function unit.

  On the other hand, the temperature control function unit is generally included between the upper cover member and the lower cover member in a mode of being included in the temperature control function unit housing. And a high pressure may act on a temperature control function part instantaneously, and there exists a possibility that it may come out of a temperature control function part housing. Therefore, it is preferable that the temperature control function unit adopts a configuration having a “pressing (locking)” function with respect to the temperature control function unit housing in order to prevent the temperature control function unit from coming out of the temperature control function unit housing.

  Under the background as described above, in the conventional hot and cold water mixing device, the rotation angle regulating member has such a “pressing (locking)” function. For example, in the faucet device disclosed in Patent Document 1, a part responsible for pressing the temperature control function part and a part responsible for the rotation angle regulation are one part.

  Specifically, as shown in FIG. 7 (corresponding to FIG. 2 of Patent Document 1), in the hot and cold water mixing faucet device 101, the temperature adjustment function part 110 has an outer peripheral edge part 111 exposed in a ring shape on the front side. An annular rotation angle regulating member 140 that also serves as a pressing member is fixed to the temperature control function unit housing 112 in a state of being in contact with the outer peripheral edge 111 from the front side.

  Thereby, the rotation angle regulating member 140 is responsible for regulating the rotation angle of the temperature control handle 130 and also holding the temperature control function unit 110. Since one component serves two functions, an increase in the number of components can be suppressed.

JP 2017-31689 A

  As described above, the temperature control function unit is generally included between the upper cover member and the lower cover member in a mode that is included in the temperature control function unit housing. Conventionally, the maintenance operation of the temperature control function unit has been performed after removing both the upper cover member and the lower cover member.

  In order to improve the maintenance work efficiency, the present inventor has intensively studied whether the maintenance work can be performed with only the lower cover member removed, that is, with the upper cover member attached.

  Here, when the upper cover member does not have a hanging part that hangs downward on the front side, the entire front side is opened even when only the lower cover member is removed. There is no hindrance.

  However, in recent years, in order to improve the design, the upper cover member includes an upper cover main body portion that extends above the upper surface of the temperature control function portion, and a hanging portion that hangs downward from the upper cover main body portion on the front surface side, In many cases. In such a case, since the component (for example, the rotation angle regulating member 140 in FIG. 7) responsible for holding the temperature adjustment function unit and regulating the rotation angle of the temperature adjustment handle is a relatively large component, the upper cover member It was difficult to remove the parts without removing the parts.

  The present invention has been made based on the above findings. An object of the present invention is to provide a hot and cold water mixing device that can perform maintenance work without removing an upper cover member.

  The present invention is a hot-water / water-mixing faucet device that mixes hot water supplied from a hot-water supply source with water supplied from the water-supply source to adjust the temperature, and the temperature control function unit A temperature adjustment handle that is rotated for temperature adjustment, a rotation angle restriction member that restricts the rotation angle of the temperature adjustment handle, an upper cover member provided on the upper surface side of the temperature adjustment function unit, and the temperature adjustment A lower cover member provided on the lower surface side of the function part, and a pressing member for preventing the temperature control function part from coming out of the upper cover member and the lower cover member, the upper cover member, An upper cover body portion extending above the upper surface of the temperature control function portion; and a hanging portion that hangs downward from the upper cover body portion on the front surface side where the temperature control handle is exposed. The temperature control handle from the front side When viewed in the axial direction, the rotational angle restricting member has a positional relationship that at least partially overlaps, and the pressing member is configured separately from the rotational angle restricting member. It is a hot and cold water mixing device.

  According to the present invention, although the hanging portion of the upper cover member is at least partially overlapped with the rotation angle regulating member when viewed from the front side in the axial direction of the temperature control handle, the pressing member And the rotation angle restricting member are configured separately (so as to be separable), so that it is easy to remove the pressing member and the rotation angle restricting member even when the upper cover member is not removed. It becomes easy to perform the maintenance work without removing the upper cover member.

  The temperature control function part has an outer peripheral edge part exposed to the front side in an annular shape, the temperature control function part is included in a temperature control function part housing, and the pressing member is It is preferable to have a flange member that contacts the outer peripheral edge portion in the axial direction, and a cap nut that fixes the flange member to the temperature control function unit housing.

  In this case, since the pressing member can be further separated into two parts, a flange member and a cap nut, it is easier to remove the pressing member in a state where the upper cover member is not removed. In addition, the flange member and the temperature control function unit can be engaged in the rotation direction, and the engagement position between the two can be adjusted to fix the flange member and the rotation angle regulating member in the rotation direction. In this state, the position and orientation of the rotation angle regulating member can be adjusted.

  The rotation angle restricting member is attached to and detached from the temperature control function part, and the rotation angle restricting member includes a locking part of the temperature control handle according to a rotation angle of the temperature control handle. A locking portion that cooperates to regulate further rotation of the temperature control handle, and the locking portion is attached to and detached from the temperature control function portion of the rotation angle regulating member; It is preferable that the position and orientation be such that a stepped portion is formed on the lower side of the rotation angle restricting member so as to protrude toward the front side in the axial direction and on the upper side of the rotation angle restricting member.

  In this case, the rotation angle regulating member can be attached and detached while avoiding the upper cover member that is attached by using the stepped portion (and the concave portion thereabove) by the locked portion of the rotation angle regulating member. .

  According to the present invention, although the hanging portion of the upper cover member is at least partially overlapped with the rotation angle regulating member when viewed from the front side in the axial direction of the temperature control handle, the pressing member And the rotation angle restricting member are configured separately (so as to be separable), so that it is easy to remove the pressing member and the rotation angle restricting member even when the upper cover member is not removed. It becomes easy to perform the maintenance work without removing the upper cover member.
