Description

The present invention relates to a rectifier for bathroom preheating used when preheating (preheating) the interior of a bathroom prior to bathing.

  When bathing in extreme cold, such as in the winter when the outside air temperature is low, everyone experiences a lot of uncomfortable feelings as they enter the bathroom and shake very cold. As a measure for wiping away such unpleasant feelings at the time of bathing, conventionally, as shown in FIG. 9, as shown in FIG. 9, hot water is sprayed for several minutes from a shower head 20 that is originally provided in the bathroom before bathing. Then, the temperature in the bathroom is increased by the steam (hot air), or the heater (indoor unit) 21 installed on the wall surface in the bathroom is operated several minutes before bathing. The preheating method which raises was adopted.

  However, when water is sprinkled from the shower head in advance for several minutes before bathing, the utility cost is likely to increase due to wasteful use of hot water. In particular, when the scheduled bathing is extended for some reason, the useless amount of hot water is increased due to the forgotten stoppage of hot water from the shower head, which further increases the utility cost. In addition, when a heater is installed in the bathroom, there is a problem that not only the equipment cost increases but also the running cost increases, so that the utility cost is further increased than in the case of the pre-shower.

  The present invention has been made in view of the above circumstances, effectively utilizing the hot water filling in the bathtub, while suppressing the increase in the utility cost and the utility cost due to wasteful use of hot water, while keeping the inside of the bathroom. It is an object of the present invention to provide a bathroom preheating rectifier that can be preheated to a comfortable and reasonable temperature.

In order to achieve the above object, a bathroom preheating rectifying appliance according to the present invention has an appliance main body having a hot water passage that converts hot water fed from a hot water discharge pipe into a downward flow at the center, and A cylindrical valve member having a hot water passage communicating with the hot water passage and connected and held in a fixed state at a lower end portion in the instrument main body, and the instrument at the lower end portion of the instrument main body in a state of covering the outer periphery of the valve member while is composed of a rotary member which is rotated operably assembled held about an axis passing through the hot water passage of the body and the valve member is attached to the front end side of the hot water supply discharge pipe to a bathtub,

On the other hand, when the valve member is closed, it is configured to discharge hot water into the bathtub only from the normal hot water discharge port,
Further, the means for misting the branched hot water includes a divided passage for dividing and flowing the branched hot water, swirling blades for imparting a turning force to the hot water flowing into the divided passages, and swirling by the swirling blades. And a squeezing part that squeezes the hot water to which the force is applied and sprays water from the water spout of the mist water .

  According to the present invention having the above-described configuration (Claim 1), part of the hot water fed from the hot water discharge pipe is rectified by the strainer when the hot water is filled in the bathtub prior to bathing. After that, it is discharged from the normal hot water outlet into the bathtub, and at the same time, some of the other branched hot water is misted and then sprayed into the bathroom from the water sprinkler. When the bathing is completed, the temperature in the bathroom gradually rises as the filling of the bath progresses, and when the filling of the bath reaches the appropriate level, that is, when the bathing is completed The room is raised to a comfortable ambient temperature that does not shake or cause discomfort. Therefore, it is only necessary to attach it to the tip of the discharge pipe for hot water supply. Not only can the equipment cost be significantly reduced compared to the case where a heater is installed in the bathroom, but also hot water such as when hot water is sprayed from the shower head.

To do. When the hot water filling in the bathtub 22 reaches an appropriate amount, that is, when the preparation for bathing is completed, the temperature in the bathroom 24 is raised to a comfortable atmospheric temperature without causing tremors or discomfort. It will be. Therefore, by simply attaching the rectifier 3 to the tip of the hot water supply discharge pipe 1, the equipment cost can be significantly reduced as compared with the case where a heater is installed, and the hot water can be reduced compared with the case where hot water is sprinkled from a shower head. The bathroom 24 can be preheated to a comfortable temperature reasonably and efficiently while minimizing wasteful use and associated increase in utility costs. Even when bathing in extreme cold, the bathroom 24 As soon as you enter, you can avoid being very cold and trembling or feeling uncomfortable. Moreover, since the strainer 6 comes into contact with the hot water, the hot water chlorine is removed by the copper ions generated from the strainer 6, and hot water that is harmless to the human body can be supplied into the bathtub 22.

  Further, when bathing in warm weather such as in the summer, the valve member 11 is switched to the closed state by rotating the rotating member 9, thereby stopping the spraying of mist water and eliminating unnecessary use of hot water. In addition, it is possible to efficiently fill the hot water by discharging the rectified hot water into the bathtub 22 only from the normal hot water discharge port 7. Also in this case, since the strainer 6 comes into contact with hot water, the chlorine of the hot water can be removed by the copper ions generated from the strainer 6, and hot water that is harmless to the human body can be supplied into the bathtub 22.

  By the way, the present inventors use the rectifying device 3 having the configuration described in the above embodiment to sprinkle (spray) mist water from the water spout 8 at the same time as the hot water filling. An experiment for measuring temperature change was performed, and the results shown in Table 1 and FIG. 6 were obtained. The measurement conditions in this experiment were that the initial temperature in the bathroom was 15 ° C., the hot water supply temperature was 50 ° C., and the ventilation fan stopped operating.

  As is apparent from the experimental results in Table 1 and FIG. 6, the room temperature (bathroom temperature) gradually increased with the elapse of the hot water filling time (unit: minutes, seconds), and the room temperature after 20 minutes had cooled. The temperature rose to 32 ° C where no discomfort was felt. After 20 minutes, the amount of hot water in the bathtub 22 was accumulated up to approximately 80%, and preparations for bathing were completed at any time, and hot water supply was stopped at that time. Even after a lapse of 2 to 3 minutes from the stop of the hot water supply, the room temperature was kept at about 29 ° C., and there was no coldness or discomfort.

  FIG. 7 shows the setting by turning the dial 25 to set the amount of hot water without setting the bathroom preheating rectifier 3 according to the present invention directly to the hot water discharge pipe 1 in the hot water mixing tap 23. When the amount of water is reached, the automatic shutoff device 26 that closes the valve and automatically stops the hot water supply may be attached to the discharge port of the automatic water stop device 26 (this is well known and the description of the specific structure is omitted). . In this case, it is possible to automatically stop water spraying of mist water from a plurality of water spray ports 8 at the same time as stopping automatic hot water supply from the normal discharge port 7 into the bathtub 22, further reducing waste of hot water. However, the preheating function in the bathroom 24 can be achieved.

FIG. 8 shows a copper hot water supply member 30 provided in the central hot water passage 5 of the appliance main body 4 of the bathroom preheating rectifier 3 shown in FIG. 2, and the hot water fed from the hot water supply discharge pipe 1 is made of copper. The reference example comprised so that the water flow member 30 and the copper strainer 6 might be contacted is shown. In this case , the copper ion effect is large. The water passage member 30 is formed into a cylindrical body with, for example, a large number of copper fibers entangled, and is configured to generate a large number of copper ions by contact with hot water flowing through the central hot water passage 5. Note that a water-permeable member in which a large number of copper fibers are entangled to form a bottomed cylindrical body and a plurality of communication holes communicating with the strainer 6 are formed at the bottom may be used. When a plurality of copper particles are accommodated inside the water-permeable member, since hot water flows between the copper particles, a larger number of copper ions are generated, and the ion effect of copper can be improved.
