Description

  The present invention relates to a hot and cold water mixing tap capable of adjusting the temperature of mixed water by rotating one handle.

  Generally, this kind of hot and cold water mixing tap is provided with a main body having a hot water inlet, a water inlet and a mixed water outlet, as described in Patent Documents 1 and 2, and fixed to the main body. Fixed valve, a movable valve rotatably provided on the stopper body, and slidably contacted with one end surface of the fixed valve, and a stopper body rotatably provided and non-rotatably connected to the movable valve. And a handle. Each of the fixed valves has a first hot water hole, a first water hole, and a first water hole each having one end opened to an end surface facing the movable valve, and each other end communicating with the hot water inlet, the water inlet, and the mixed water outlet. One mixing hole is formed. On the other hand, the movable valve is formed with a second hot water hole, a second water hole, and a second mixing hole that open to the end face facing the fixed valve, respectively.

  When the movable valve is rotated by the handle and positioned within a predetermined angle range, the first and second hot water holes communicate with each other, and the first and second water holes communicate with each other. On the other hand, the first and second mixing holes are always in communication. While the first and second hot water holes communicate with each other, the hot water introduced into the plug body from the hot water inlet sequentially passes through the first and second hot water holes when the first and second water holes communicate with each other. Then, it enters the mixing chamber formed inside the stopper body, and the water introduced into the stopper body from the water introduction port sequentially passes through the first and second water holes and then enters the mixing chamber. And after mixing hot water and water in a mixing chamber, after passing through the 2nd mixing hole and the 1st mixing hole one by one, it becomes mixed water and is discharged from a mixed water discharge outlet.

  The temperature of the mixed water discharged from the mixed water discharge port changes according to the turning operation of the handle. That is, when the movable valve is rotated by the handle, the communication area of the first and second hot water holes and the communication area of the first and second water holes change. In this case, when the movable valve is rotated to the high temperature position side, the communication area of the first and second hot water holes is increased, while the communication area of the first and second water holes is decreased. As a result, the temperature of the mixed water discharged from the mixed water discharge port increases. Conversely, when the movable valve is rotated to the low temperature position side, the communication area of the first and second hot water holes is reduced, while the communication area of the first and second water holes is increased. Therefore, the temperature of the mixed water discharged from the mixed water discharge port is lowered.

JP-A-6-185539 JP-A-8-159309

  In the above-described conventional hot and cold water mixing tap, when the handle is positioned at the center of the rotation range in the spring and autumn, the temperature of the mixed water is the highest frequency of use by the user (hereinafter referred to as the optimum temperature). Shall be. However, even if the position of the handle is the same, if the temperature of the water (tap water) introduced into the water inlet changes, the temperature of the mixed water changes accordingly. Therefore, in the summer and winter season, even if the handle is rotated to the center position, the mixed water having the optimum temperature cannot be obtained. In order to obtain mixed water at the optimum temperature, the handle must be adjusted to a lower temperature side than the center of its rotation range in summer, and the handle must be adjusted to a higher temperature in winter. For this reason, even if there is a request that the conventional hot and cold water mixing tap always wants to obtain mixed water at the optimum temperature when the handle is rotated to a predetermined position (for example, the center position of the rotation range), There was a problem that we could not respond to it.

In order to solve the above problems, the present invention provides a stopper body having a hot water inlet, a water inlet and a mixed water outlet, a fixed valve provided in the stopper body in a non-rotatable manner, and the stopper body. A movable valve that is rotatably provided and that is slidably contacted with one end surface of the fixed valve, and a handle having a base end portion that is rotatably provided on the plug body and that rotates the movable valve. The fixed valve has a first hot water hole whose one end is open to an end surface facing the movable valve, and the other end is in communication with the hot water inlet, the water inlet and the mixed water outlet, respectively. A first water hole and a first mixing hole are formed, and the movable valve is formed with a second hot water hole, a second water hole, and a second mixing hole respectively opened on an end surface facing the fixed valve. The first mixing hole and the second mixing hole communicate with each other with a communication area of a predetermined size or more, and the first hot water hole and the second mixing hole In the hot and cold water mixing plug, the communication area between the two hot water holes and the communication area between the first water hole and the second water hole change such that when one is increased as the movable valve rotates, the other is decreased. A first state in which the handle is non-rotatably connected to the movable valve and a second state in which the handle is allowed to rotate with respect to the movable valve between the movable valve and the handle. And an intermittent means that can be switched to each other.
In this case, the intermittent means is provided inside the proximal end portion of the handle so as to be movable in the vertical direction between an upper position and a lower position, and protrudes upward from the upper surface of the proximal end portion of the handle at the upper end portion. A pressing member provided with an operating portion; and a biasing means for biasing the pressing member upward. When the pressing member is located at the upper position, the intermittent means is in the first state. When the pressing member is in the lower position, the intermittent means may be configured to be in the second state, or when the pressing member is in the upper position. When the intermittent means is in the second state and the pressing member is in the lower position, the intermittent means may be in the first state.

  According to the hot and cold water mixing tap of the present invention having the above-described configuration, the handle is appropriately rotated to a position where the temperature of the mixed water becomes the optimum temperature while maintaining the state where the handle is non-rotatably connected to the movable valve by the intermittent means. Let Thereafter, the handle is made rotatable with respect to the movable valve by the intermittent means. Then, while maintaining the state, the handle is rotated to a desired position, for example, the center of the rotation range of the handle. By adjusting the position of the handle in this way, it is possible to always obtain mixed water at the optimum temperature when the handle is rotated to a desired position regardless of the temperature of the water.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 2 shows an embodiment of a hot and cold water mixing tap according to the present invention. This mixing plug is configured in the same manner as a known hot and cold mixing plug except for the intermittent means 11 described later. Therefore, first, the same parts as those of the known hot and cold water mixing tap will be described, and then the intermittent means as the main part of the present invention will be described.

  First, a description will be given of the same part as a known hot and cold water mixing plug. In FIG. 2, reference numeral 1 denotes a plug body. The plug body 1 is a hollow body having a substantially square cross section, and is arranged with its longitudinal direction oriented in the horizontal direction. A hot water inlet 1a and a water inlet 1b are respectively provided at one end and the other end of the back surface of the stopper body 1 in the longitudinal direction. A projecting portion 1 c is formed at the central portion in the longitudinal direction of the upper surface of the plug body 1. A mixed water discharge port 1d is formed on the outer surface facing the front of the protruding portion 1c.

  A fixed valve portion (fixed valve) 2 is formed integrally with the protruding portion 1c at the upper end portion of the protruding portion 1c. The fixed valve portion 2 may be formed separately from the protruding portion 1c and fixed to the protruding portion 1c. The fixed valve part 2 is formed with a hot water hole (first hot water hole) 2a, a water hole (first water hole) 2b, and a mixing hole (first mixing hole) 2c. One end of each hole 2a, 2b, 2c opens to the upper end surface of the fixed valve portion 2 (the upper end surface of the protruding portion 1c). The other end of the hot water hole 1d communicates with the hot water inlet 1a, the other end of the water hole 2b communicates with the water inlet 1b, and the other end of the mixing hole 2c communicates with the mixed water outlet 1d.

  A base end portion of the discharge pipe 3 is fitted to the lower portion of the projecting portion 1c so as to be rotatable in a watertight state. The inside of the discharge pipe 3 is always in communication with the mixed water discharge port 1d regardless of the rotational position of the discharge pipe 3. From the tip opening of the discharge pipe 3, hot water, water, or mixed water in which they are mixed is discharged according to the rotational position of the handle 10 described later. A cylindrical valve retainer 4 is screwed and fixed to the upper portion of the protruding portion 1c. Thereby, the base end portion of the discharge pipe 3 is prevented from coming out upward from the protruding portion 1c.

  A movable valve 5 is provided inside the valve presser 4. The movable valve 5 has a valve body 6 and first, second and third valve bodies 7, 8 and 9. The valve body 6 is fitted inside the valve presser 4 so as to be rotatable within a predetermined angle range (in this embodiment, a range of 180 ° in the circumferential direction). The 1st, 2nd and 3rd valve bodies 7, 8, and 9 have made the shape of a disk, and the 1st valve hole (2nd hot water hole) which penetrates each center part up and down in each center part. 7a, a second valve hole (second water hole) 8a and a third valve hole (second mixing hole) 9a are formed. The first, second, and third valve bodies 7, 8, 9 are fixed to the lower end surface of the valve body 6. The lower end surfaces of the first, second and third valve bodies 7, 8 and 9 are slidably pressed against the upper end surface of the fixed valve portion 2 in a watertight state. The first, second and third valve bodies 7, 8, 9 may be formed integrally with the lower end portion of the valve body 6.

  The first and second valve holes 7a and 8a are opposed to and separated from the hot water hole 2a and the water hole 2b, respectively, according to the rotational position of the valve body 6. In addition, the opposing area of the first valve hole 7a and the hot water hole 2a (referred to as a communication area; hereinafter the same) and the opposing area of the second valve hole 8a and the water hole 2b are accompanied by the rotation of the valve body 6. As one increases, the other decreases. That is, when the valve body 6 is rotated to the neutral position which is the center position of the rotation range, the opposing area between the first valve hole 7a and the hot water hole 2a, and the second valve hole 8a and the water hole 2b The facing area is the same. When the valve body 5 is rotated in one direction (clockwise in FIG. 2) from the neutral position, the opposing area between the first valve hole 7a and the hot water hole 2a increases as the valve body 6 rotates. The facing area between the second valve hole 8a and the water hole 2b decreases. When the valve body 8 is rotated by a maximum angle (90 ° in this embodiment) toward one direction, the opposing area between the first valve hole 7a and the hot water hole 2a is maximized, while the second valve The hole 8a is separated from the water hole 2b, and the space between them is blocked. Hereinafter, the rotation position of the valve body 6 at this time is referred to as a high temperature side limit position. Conversely, when the valve body 6 is rotated in the other direction from the neutral position, the facing area between the first valve hole 7a and the hot water hole 2a decreases, while the facing area between the second valve hole 8a and the water hole 2b is reduced. Increase. When the valve body 6 is rotated by a maximum angle in the other direction (in this embodiment, 90 °, which is the same as the angle between the neutral position and the high temperature side limit position), the first valve hole 7a. While being spaced apart from the hot water hole 2a in the circumferential direction, the space between them is blocked, while the communication area between the second valve hole 8a and the water hole 2b is maximized. Hereinafter, the rotation position of the valve body 6 at this time is referred to as a low temperature side limit position. On the other hand, the third valve hole 9a always communicates with the mixing hole 2c with a communication area of a predetermined size or more regardless of the rotational position of the valve body 6.

  Hot water that has entered the plug body 1 from the hot water inlet 1a passes through the hot water hole 2a and the first valve hole 7a, and then enters a mixing chamber (not shown) formed in the lower portion of the valve body 6. Similarly, water that has entered the plug body 1 from the water inlet 1b passes through the water hole 2b and the second valve hole 8a, and then enters the mixing chamber. When the valve body 6 is located at the high temperature side limit position or the low temperature side limit position, hot water or water enters the mixing chamber alone, but the valve body 6 is located between the high temperature side limit position and the low temperature side limit position. During this time, hot water and water enter the mixing chamber at the same time and are mixed in the mixing chamber. Hot water, water or mixed water in the mixing chamber sequentially passes through the third valve hole 9a and the mixing hole 2c, and enters the discharge pipe 3 from the mixed water discharge port 1d. And it discharges from the front-end | tip opening part of the discharge pipe 3. FIG.

  A receiving portion 10 a formed at the base end portion of the handle 10 is fitted to the outer peripheral surface of the upper end portion of the valve presser 4. The accommodating portion 10a is connected to the upper end portion of the valve presser 4 so as to be rotatable by a predetermined angle in the vertical direction. As a result, the gripping part 10b extending forward from the accommodating part 10a rotates in the vertical direction around the accommodating part 10a. The range of rotation of the handle 10 in the vertical direction is restricted between the stop position and the supply position from which the tip of the grip portion 10b is rotated upward by a predetermined angle. When the handle 10 is rotated to the supply position, hot water, water or mixed water is discharged from the discharge pipe 3. Conversely, when the handle 10 is rotated to the stop position, the discharge of hot water or the like from the discharge pipe 3 is stopped. Since the configuration for achieving such an action is well known and is not the main part of the present invention, its detailed description is omitted.

  The accommodating portion 10a of the handle 10 is connected to the upper end portion of the valve presser 4 so as to be rotatable in the horizontal direction even when the handle portion 10a is rotated to either the stop position or the supply position. As a result, the handle 10 can be rotated in the horizontal direction. The horizontal rotation range of the handle 10 is restricted to a predetermined angle range (140 ° range in this embodiment) by a stopper mechanism (not shown).

  Next, the interrupting means as the main part of the present invention will be described. In this embodiment, the interrupting mechanism 11 is used as the interrupting means as shown in FIG. The intermittence mechanism 11 is provided between the handle 10 and the valve main body 6, and has a first state in which the handle 10 is connected to the valve main body 6 in a non-rotatable manner in the horizontal direction, and the handle 10 according to the following configuration. Can be switched to the second state in which the valve body 6 can be freely rotated in the horizontal direction with respect to the valve body 6.

  That is, the intermittent mechanism 11 has a connecting shaft portion 12 and an operation button (pressing member) 13. The connecting shaft portion 12 is provided at the upper end portion of the valve body 6 so as not to rotate, and is arranged with its axis line coincident with the axis line of the valve body 6. A spline portion 12 a is formed on the outer peripheral surface of the upper end portion of the connecting shaft portion 12.

  The operation button 13 has an upper small-diameter portion (operation portion) 13 a and a lower large-diameter portion 13 b, and is arranged such that its axis coincides with the axis of the connecting shaft portion 12. The small-diameter portion 13a can be moved in a vertical direction in a through-hole 10c penetrating the central portion of the upper wall portion of the accommodating portion 10a of the handle 10, but is fitted non-rotatably. Therefore, the operation button 13 rotates integrally with the handle 10.

  Between the lower end surface of the large-diameter portion 13b and the upper end surface of the valve body 6, a coil spring 14 serving as an urging means is provided. The operation button 13 is biased upward by the coil spring 14, and the upper end surface of the large diameter portion 132 b is brought into contact with the upper wall portion of the housing portion 10 a of the handle 10. Hereinafter, the position of the operation button 13 at this time is referred to as an upper position.

  A connecting hole 13c extending upward from the lower end surface is formed in the large diameter portion 13b. The connecting hole 13 c is arranged with its axis line coincident with the axis line of the connecting shaft portion 12. When the operation button 13 is positioned at the upper position, the upper portion of the connecting shaft portion 12 is inserted into the lower portion of the connecting hole 13c so as to be movable in the vertical direction. When the operation button 13 is moved downward against the urging force of the coil spring 14 from this state, the upper bottom surface of the connection hole 13c hits the upper end surface of the connection shaft portion 12, and the operation button 13 further moves downward. I can't do that. Hereinafter, the position of the operation button 13 at this time is referred to as a lower position.

  A spline hole 13d is formed at the lower end of the connecting hole 13c. When the operation button 13 is positioned at the upper position, the spline portion 12a of the connecting shaft portion 12 is fitted in the spline hole portion 13d so as not to be rotatable and movable in the vertical direction. Therefore, when the operation button 13 is in the upper position, the handle 10 is non-rotatably connected to the valve body 6 via the operation button 13 and the connecting shaft portion 12, and the handle 10 is rotated in the horizontal direction. The movement is transmitted to the valve body 6 via the operation button 13 and the connecting shaft portion 12. The state of the coupling mechanism 11 at this time is the first state. When the operation button 13 is moved to the lower position against the biasing force of the coil spring 14, the spline portion 12a moves upward relative to the operation button 13 and comes out of the spline hole portion 13d. As a result, the operation button 13 can be rotated with respect to the connecting shaft portion 12, and as a result, the handle 10 can be rotated with respect to the valve body 6 in the horizontal direction. The state of the coupling mechanism 11 at this time is the second state.

  In the hot and cold water mixing plug having the above-described configuration, the valve body 6 is now positioned in the neutral position, and the handle 10 is positioned with its gripping portion 10b oriented in a direction perpendicular to the longitudinal direction of the plug body 1 (hereinafter referred to as “the plug body 1”). The position of the handle 10 at this time is referred to as a center position). Then, when the valve body 6 and the handle 10 are positioned in such a position, it is assumed that mixed water having a temperature that the user feels as an optimum temperature is discharged from the discharge pipe 3 in spring and autumn. The handle 10 can be rotated by 70 ° from the center position to the high temperature side and the low temperature side, respectively.

  In winter, the temperature of water (tap water) supplied to the water inlet 1b of the plug body 1 is lower than the temperature of water supplied in spring or autumn. For this reason, even if the handle | steering-wheel 10 rotates to a center position, the mixed water of optimal temperature cannot be obtained. This is because the temperature of the mixed water discharged from the discharge pipe 3 becomes lower than the optimum temperature by the amount of water temperature drop. In such a case, by performing the following operation, it is possible to obtain mixed water having an optimum temperature when the handle 10 is positioned at the center position.

  First, the handle 10 is rotated from the center position to the high temperature side with the handle 10 positioned at the supply position and the operation button 13 positioned at the upper position. Then, the valve body 6 rotates to the high temperature side following the rotation of the handle 10, so that the temperature of the mixed water discharged from the discharge pipe 3 rises with the rotation of the handle 10. When the temperature of the mixed water reaches the optimum temperature, the handle 10 is stopped. Next, the operation button 13 is pushed and moved to the lower position. Thereby, the handle 10 is brought into a rotatable state with respect to the valve body 6. While maintaining the state where the operation button 13 is positioned at the lower position, the handle 10 is rotated to the low temperature side to the center position. When the handle 10 reaches the center position, the operation button 13 is moved to the upper position by the coil spring 14. Then, the handle 10 is connected to the valve body 6 so as not to rotate. In this state, the valve body 6 is positioned on the higher temperature side than the neutral position even though the handle 10 is positioned at the center position. Therefore, even in winter when the water temperature is low, the water mixture at the optimum temperature can be obtained by positioning the handle 10 at the center position.

  Conversely, in the summer when the temperature of the water supplied to the water inlet 1b is higher than in the spring or autumn, the handle 10 is rotated to the low temperature side until the optimum temperature is obtained. Next, the handle 10 is returned to the center position while maintaining the state where the operation button 13 is positioned at the lower position. Thereafter, the operation button 13 is returned to the upper position by the coil spring 14. As a result, mixed water at the optimum temperature can be obtained by positioning the handle 10 at the center position even in summer.

  Further, in this embodiment, the range of rotation from the neutral position of the valve body 6 to the high temperature side and the low temperature side (both 90 °) is the range of rotation from the center position of the handle 10 to the high temperature side and the low temperature side. (Both 70 °), the rotation range of the handle 10 is maximized unless the adjustment angle from the neutral position of the valve body 6 exceeds a predetermined angle (20 ° in this embodiment). Can be secured. If the adjustment angle from the neutral position of the valve body 6 to the high temperature side or the low temperature side exceeds 20 °, the rotation range of the handle 10 to the high temperature side or the low temperature side is restricted by the rotation range of the valve body 6. As a result, the adjustment angle of the valve body 6 becomes smaller than 70 ° by an amount exceeding 20 °.

  3 and 4 show the main part of the second embodiment of the present invention. In this embodiment, an intermittent mechanism (interrupting means) 20 is used instead of the intermittent mechanism 11. Contrary to the intermittent mechanism 11 described above, when the operation button 21 is positioned at the lower position, the intermittent mechanism 20 is connected to the valve body 6 so as not to rotate in the horizontal direction (first state). When the button 21 is positioned at the upper position, the handle 10 is configured to be rotatable in the horizontal direction with respect to the valve body 6 (second state).

  That is, the operation button 21 has a main body part (operation part) 21a penetrating through the through hole 10c of the handle 10 so as to be movable in the vertical direction and turnable. A contact portion 21b having a diameter larger than that of the portion 21a is formed. The operation button 21 is urged upward by a coil spring 22 as urging means, and the abutting portion 21b abuts against the upper wall portion of the accommodating portion 10a unless pressed down. The position of the operation button 21 at this time is the upper position. When the operation button 21 located at the upper position is pushed to the lower position shown in FIG. 4 against the coil spring 22 as the biasing means, the movable member 23 resists the biasing force of the coil spring 24 as the biasing means. The spline hole portion 23a of the movable member 23 is fitted to the spline portion 12a of the connecting shaft portion 12 so as not to rotate. As a result, the handle 10 is rotated in the horizontal direction on the valve body 6 via the fixed member 25 fixed to the handle 10 and the movable member 23 fitted to the fixed member 25 so as not to be rotatable and movable in the vertical direction. Linked impossible. When the operation button 21 located at the lower position can be freely moved up and down, the movable member 23 is slightly pushed back upward by the coil spring 24 and moved to the engagement position. Accordingly, the operation button 21 is also moved slightly upward. Even when the movable member 23 is located at the engagement position, the spline hole portion 23a of the movable member 23 is non-rotatably fitted to the spline portion 12a of the connecting shaft portion 12. Therefore, when the valve body 6 is rotated by the handle 10, the operation button 21 may be maintained at the lower position, or the operation button 21 may be moved to the engagement position.

  When the operation button 21 located at the engagement position is pressed and moved again to the lower position and then released, the operation button 21 is moved to the upper position by the coil spring 22. Following this, the movable member 23 is moved upward to the original position by the coil spring 24. As a result, the movable member 23 is separated upward from the connecting shaft portion 12, and the handle 10 can be rotated with respect to the valve body 6. Since the configuration for causing the operation button 21 and the movable member 23 to behave as described above is well known, for example, as described in the microfilm of Japanese Utility Model Application No. 60-80893 (Japanese Utility Model Application No. 61-198868). Detailed description thereof will be omitted.

In addition, this invention is not limited to said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, in the above embodiment, the rotation range from the neutral position of the valve body 6 to the high temperature side and the low temperature side is different from the rotation range from the center position of the handle 10 to the high temperature side and the low temperature side. However, it may be the same angle.
Further, in the above embodiment, when the handle 10 is positioned at the center position, mixed water having the optimum temperature is obtained. However, the handle is positioned at a position deviated from the center position toward the high temperature side or the low temperature side. When 10 is located, mixed water having an optimum temperature may be obtained.
In the following embodiment, the operation button 21 is urged upward by the coil spring 22, but when the movable member 23 is provided on the operation button 21 so as not to move, the coil spring 22 is omitted. The movable member 23 and the operation button 21 may be urged upward by the coil spring 24. In that case, the coil spring 24 serves as a biasing means that biases the operation button 21 upward.
