Description

一种排残留水切换组件 技术领域
本发明涉及卫浴领域，尤其涉及切换组件。
背景技术
日常家庭中的淋浴花洒在淋浴停止后，管道中会有一部分残留水无法被排出，下一次淋浴的时候，这些残留水就变成冷水排出。因此，人们在淋浴时都习惯先让花洒排冷一段时间后再开始进行正常的淋浴。但是，现在的家庭中，淋浴设备往往不止一个，比如常见的顶喷花洒和手持花洒组成的淋浴系统。顶喷花洒和手持花洒的管道是相互独立的，因此管道中的残留水也是相互独立的。假设用户在淋浴前对手持花洒进行了排冷，在淋浴过程中需要切换成顶喷花洒时，顶喷花洒依然会排出一段时间的冷水，往往这个时候用户不会留意到需要再次进行排冷，就很容易被冷水淋到，淋浴体验比较差。而即使用户注意到并且进行了二次排冷，淋浴过程也被中断了，淋浴体验同样不佳。
发明内容
本发明所要解决的主要技术问题是提供一种排残留水切换组件，在其中一个出水通道出水时，另一个出水通道内的残留水排出；当切换到另一个出水通道排水时，原先的出水通道内的残留水排出。
为了解决上述的技术问题，本发明提供了一种排残留水切换组件，包括主体以及设置于主体内的切换件；所述主体包括一进水通道、第一出水通道、第二出水通道以及一排水通道；
所述切换件具有一进水口、第一过水孔、第二过水孔和排水孔；其中进水口与进水通道连通，第一过水孔、第二过水孔分别对应与第一出水通道、第二出水通道连通，排水孔与排水通道连通；
操作所述切换件使得该进水口与第一过水孔、第二过水孔中的一个连通，此时，第一过水孔、第二过水孔中的另一个通过排水孔与排水通道连通；所述进水口与第一过水孔连通时，进水通道内的水通过第一过水孔流入第一出水通道内， 第二出水通道内的残留水通过第二过水孔和排水孔后经排水通道排出；所述进水口与第二过水孔连通时，进水通道内的水通过第二过水孔流入第二出水通道内，第一出水通道内的残留水通过第一过水孔和排水孔后经排水通道排出。
在一较佳实施例中：所述切换件包括一转动轴、与所述转动轴连动设置的转动片、以及一保持静止的静止片；
所述进水口设置于所述转动片，所述转动片的下表面与进水口不同的位置设有一内凹的过水槽；所述第一过水孔、第二过水孔和排水孔分别设置于所述静止片上；当所述进水口与第一过水孔、第二过水孔中的一个连通时，所述过水槽将第一过水孔、第二过水孔中的另一个与排水孔连通。
在一较佳实施例中：所述排水孔在靠近过水槽的一侧具有与所述过水槽相对应的形状，远离过水槽的一侧为圆孔；所述圆孔与排水通道连通。
在一较佳实施例中：所述过水槽的横截面积大于圆孔的横截面积。
在一较佳实施例中：所述第一过水孔、第二过水孔为横截面积与所述圆孔相同的贯穿孔。
在一较佳实施例中：所述进水口从所述转动片的边缘沿着径向设置。
在一较佳实施例中：所述进水口始终最少与第一过水孔、第二过水孔中的一个连通。
在一较佳实施例中：所述主体包括一横管，其一端为开口端；所述切换件沿着轴向安装于横管内，且所述转动轴的末端暴露于开口端外；一操作把手与转动轴的末端转动连接，转动把手带动转动轴转动。
在一较佳实施例中：所述第一出水通道、第二出水通道分别垂直设置于所述横管的上下两侧；所述进水通道、排水通道与第二出水通道位于同一侧。
在一较佳实施例中：所述第一出水通道连接顶喷花洒、第二出水通道连接手持花洒。
相较于现有技术，本发明的技术方案具备以下有益效果：
1.本发明提供的一种排残留水切换组件，通过进水口与一个过水孔连通，实现了第一出水通道的出水功能；与此同时，另一个过水孔与排水孔连通，使得在第一出水通道出水的同时，第二出水通道内的残留水经过排水通道排出。这样就实现了排水和通水同步进行的目的。当用户从第一出水通道切换到第二出水通道 时，第二出水通道能够马上流出热水，避免用户被冷水淋到从而影响淋浴用户体验。并且，第一出水通道内的残留水也在第二出水通道通水的同时被排水通道排出。能够保证用户在第一出水通道、第二出水通道中进行自由切换的同时，都不会被冷水淋到。
此外，由于上一次淋浴后，总有一路冷水被排出，这意味着每次用户淋浴时，最多只需要排一次冷水即可，用户无需为此而形成淋浴前分别排两次冷水的习惯，使得淋浴前的等待时间被缩短，淋浴体验提升。
2.本发明提供的一种排残留水切换组件，切换阀的转动轴在转动过程中，转动片上的进水孔始终保持最少与第一过水孔、第二过水孔中的一个连通。这样，当淋浴开始后，无论用户如何进行切换操作，第一出水通道、第二出水通道中最少有一个是处于通水状态的。尤其当用户使用的是燃气热水器时，就不会因为切换过程中的止水状态而造成燃气热水器熄火。

具体实施方式
下文结合附图和具体实施方式对本发明做进一步说明。
参考图1-10，一种排残留水切换组件，包括主体1以及设置于主体1内的切换件2；所述主体1包括一进水通道11、第一出水通道12、第二出水通道13以及 一排水通道14；本实施例中，所述主体1包括一横管，其一端为开口端；所述切换件2沿着轴向安装于横管内。所述第一出水通道12、第二出水通道13分别垂直设置于所述横管的上下两侧；所述进水通道11、排水通道14与第二出水通道13位于同一侧。
本实施例中，所述第一出水通道12连接顶喷花洒、第二出水通道13连接手持花洒。根据需要，也可以连接其他的出水设备，比如厨房花洒，属于本实施例的简单替换，不再赘述。
所述切换件2具有一进水口21、第一过水孔22、第二过水孔23和排水孔24；其中进水口21与进水通道11连通，第一过水孔22、第二过水孔23分别对应与第一出水通道12、第二出水通道13连通，排水孔24与排水通道14连通；
操作所述切换件2使得该进水口21与第一过水孔22、第二过水孔23中的一个连通，此时，第一过水孔22、第二过水孔23中的另一个通过排水孔24与排水通道14连通。
因此，形成如下的出水效果：所述进水口21与第一过水孔22连通时，进水通道11内的水通过第一过水孔22流入第一出水通道12内，第二出水通道13内的残留水通过第二过水孔23和排水孔24后经排水通道14排出；所述进水口21与第二过水孔23连通时，进水通道11内的水通过第二过水孔23流入第二出水通道13内，第一出水通道12内的残留水通过第一过水孔22和排水孔24后经排水通道14排出。
经过上述的设计，使得在第一出水通道12出水的同时，第二出水通道13内的残留水经过排水通道14排出。这样就实现了排水和通水同步进行的目的。当用户从第一出水通道12切换到第二出水通道13时，第二出水通道13能够马上流出热水，避免用户被冷水淋到从而影响淋浴用户体验。并且，第一出水12通道内的残留水也在第二出水通道13通水的同时被排水通道14排出。能够保证用户在第一出水通道12、第二出水通道13中进行自由切换的同时，都不会被冷水淋到。
为了实现上述的设计，本实施例的具体结构如下：
所述切换件2包括一转动轴25、与所述转动轴25连动设置的转动片26、以及一保持静止的静止片27；所述转动轴25的末端暴露于开口端外；一操作把手15与转动轴25的末端转动连接，转动把手15带动转动轴25转动。
还包括：切换件套体20、上盖28、下盖29。上盖28与转动轴25固定连接，转动片26的上端面开有卡槽263，上盖28的下端面设有卡片281，上盖28与转动片26卡接固定；静止片27的周壁上开有卡槽271，下盖29的周壁向上延伸有卡接片291，静止片27与下盖29卡接固定；转动轴25、上盖28、转动片26、静止片27、下盖29依次装接在切换件套体20内，下盖29与切换件套体20固接。
所述进水口21设置于所述转动片26上，本实施例中，所述进水口21从所述转动片26的边缘沿着径向设置。所述转动片26的下表面与进水口21不同的位置设有一内凹的过水槽261；所述第一过水孔22、第二过水孔23和排水孔24分别设置于所述静止片27上；所述排水孔24为阶梯孔，并在靠近过水槽261的一侧具有与所述过水槽261相对应的长形孔242，远离过水槽261的一侧为圆孔241。并且，所述过水槽261的横截面积大于圆孔的横截面积。
采用上述设计后，当所述进水口21与第一过水孔22、第二过水孔23中的一个连通时，所述过水槽261将第一过水孔22、第二过水孔23中的另一个与排水孔24连通。而将所述排水孔24设置为阶梯孔，且所述过水槽261的横截面积设置为大于圆孔的横截面积，目的是为了保证转动片只要转动一个很小的角度，就能使得过水槽261分别连通第一过水孔22、第二过水孔23中的另一个与排水孔24，这样排残留水时的过水面积比较大，排水流量大，残留水可以快速被排出。
所述第一过水孔22、第二过水孔23为横截面积与所述圆孔相同的贯穿孔。
更进一步的，所述进水口21始终最少与第一过水孔22、第二过水孔23中的一个连通。这样，当淋浴开始后，无论用户如何进行切换操作，第一出水通道12、第二出水通道13中最少有一个是处于通水状态的。当用户使用的是燃气热水器时，就不会因为切换过程中的止水状态而造成燃气热水器熄火。
所述第一出水通道12连接顶喷花洒、第二出水通道13连接手持花洒：
如图1、2、5、6、7所示，需要使用顶喷花洒时，旋转转动轴25，转动轴25带动上盖28、转动片26转动，至进水口21与静止片27上的第一过水孔22连通，水流经进水通道11、进水口21、第一过水孔22、第一出水通道12，由顶喷花洒出水；

工业实用性
本发明一种排残留水切换组件，通过其进水口与一个过水孔连通，实现了第一出水通道的出水功能；与此同时，另一个过水孔与排水孔连通，使得在第一出水通道出水的同时，第二出水通道内的残留水经过排水通道排出。实现了排水和通水同步进行的目的，能够保证用户在第一出水通道、第二出水通道中进行自由切换的同时，都不会被冷水淋到，应用广泛，具有良好的工业实用性。
