具体实施方式
下面结合附图对本发明的一种洗衣机双头排水泵进行详细描述：
如图1、图2、图3、图4及图5所示，本发明的一种洗衣机双头排水泵，具体地，采用了如下的技术方案：
一种洗衣机双头排水泵，包括泵壳，泵壳上设置进水口8，所述的泵壳上分别设置至少一个第一出水口2和至少一个第二出水口6，泵壳上对应第一出水口2、第二出水口6分别安装第一排水电机1、第二排水电机10，第一排水电机1控制第一出水口2的开启/关闭，第二排水电机10控制第二出水口6的开启/关闭。
本发明的一种洗衣机双头排水泵，在泵壳上设置共用一个进水口的第一出水口2和第二出水口6，第一出水口2是实现洗衣机排水，第二出水口6是实现水重用排水，因此本发明的双头排水泵可适用于具有水重用功能的滚筒洗衣机上，整体结构集成度高，结构简单，易于安装。
本发明所述的泵壳至少包括内部相互连通的第一泵壳4和第二泵壳9，所述的进水口8、第一出水口2分别设置在第一泵壳4上，第二出水口6设置在第二泵壳9上；所述的第一排水电机1安装在第一泵壳4上，第二排水电机10安装在第二泵壳9上。
本发明的泵壳内部连通但是非一体化设计，包括内部相互连通的第一泵壳4和第二泵壳9两部分，这样更根据实际的排水需要分别对第一泵壳4和第二泵壳9进行设计。具体地，所述的若第一泵壳4、第二泵壳9主要由第一出水口2、第二出水口6的排水扬程决定，一般的，排水口的排水扬程越大，所设置的泵壳的体积也越大。
但是，由于实际的过程中，第二出水口6连接至水重用系统，由于水重用系统需要对洗涤水进行过滤过程，为了确保过滤的充分以达到良好的过滤效果，本发明的第二出水口6的排水扬程应该小于第一出水口2。因此，本发明的第二泵壳9的体积应该小于第一泵壳4的体积。另外，第二泵壳9的体积小于第一泵壳4的体积设计，可减小本发明的双头排水泵的整体结构的体积，防止其在某一方向上长度过长，更加方便其安装。
因此，本发明的双头排水泵可以实现水重用和排水作用，可以取代后面的三通阀等复杂的结构及部件。
由于本发明第二泵壳9的体积小于第一泵壳4的体积设计，因此，本发明的进水口8应该设置在第一泵壳4上，这样可尽可能大的增大进水口8的进水量，以确保为了保证第一出水口2和第二出水口6能够顺利出水，避免了因第二泵壳9的体积限制进水口8的进水量而导致排水口排水不连续。
具体的，本发明所述的第一泵壳4上还设有与进水口8连通的第三出水口，所述的第二泵壳9连接第三出水口，以实现第一泵壳4与第二泵壳9的内部相互连通。
本发明所述的第一泵壳4包括第一泵壳主体401、进水管402、第一出水管403和第三出水管404，第一泵壳主体401内部具有中空通道，进水管402、第一出水管403和第三出水管404分别连通第一泵壳主体401的中空通道，所述的进水口8、第一出水口2、第三出水口分别设置在进水管402、第一出水管403、第三出水管404的端部。
本发明的滚筒洗衣机的排水通过进水管402进入第一泵壳4的泵壳主体401的内部中空通道中，进而分别进入与中空通道相连通的第一出水管403和第三出水管404，第三出水管404中的排水接入第二泵壳9中，从而实现了将排水分别通入到两个泵壳中，而第一泵壳4中的排水排出分别受到第一排水电机1和第二排水电机10的控制，而第二泵壳9中的排水只受到第二排水电机10的控制。
作为本发明的一种优选实施方式，所述的进水管402、第一出水管403和第三出水管404分别与第一泵壳主体401的侧壁连通，第三出水管404与进水管402同平面设置，第三出水管404与第一出水管403异面设置。这样使得第二泵壳9设置在第一泵壳4的一侧，两者并列设置，减小了本发明的双头排水泵的整体轴向长度。
进一步优选地，所述的第三出水管404和进水管402设置在第一泵壳主体401的同一侧。这样使得第二泵壳9与金水管402设置在第一泵壳4的同一侧，减小了安装上的横向宽度，更加便于安装。
为了排水顺畅以及残留污物顺利流进泵壳，以便于手动清理，作为本发明的一种优选实施方式，所述的进水管402的进水口(8)处向上倾斜5°～15°设置。
如何实现第二泵壳9与第一泵壳4之间的连通是本发明需要解决的一个重要的技术问题，具体地，可采用以下两种技术方案：
方案一，本发明的第三出水管404为一L型管路，第三出水管404的一端一体连通在第一泵壳4的侧壁上，另一端一体连通第二泵壳9的内部。这样，第一泵壳4与第二泵壳9一体成型制成，工业化集成程度更高，装配更加简单方便。
方案二，本发明所述的第二泵壳9上设置与第二出水口6连通的第二泵壳进水口901，第二泵壳进水口901连接第一泵壳4的第三出水口。具体地，所述的第二泵壳进水口901通过连接件15连通第一泵壳4的第三出水口，优选地，所述的连接件15为软质水管。这样第一泵壳4和第二泵壳9分别加工后，再进行装配，加工更加的简单，而采用软质水管连接更加容易实现，降低了加工的精度要求。
总之，所述的第一泵壳4和第二泵壳9分体设置，第二泵壳9通过连接件15连通第一泵壳4；或者，所述的第一泵壳4和第二泵壳9一体成型。
作为本发明的一种优选实施方式，本发明的第一泵壳4的整体为一内部具有中空通道的柱状结构，具体的可为圆柱状结构，柱状结构的一端端部安装第一排水电机1，所述的第一出水口2的出水方向为竖直向上，即第一出水口2的轴线垂直柱状结构的中轴线设置。柱状结构的另一端端部为盘状的第一泵壳安装部5，第一泵壳安装部5上设置螺纹安装孔，所述的第一泵壳4通过螺纹安装在滚筒洗衣机的前面板内壁上。所述的第三出水管404和进水管402均连通柱状结构的侧壁上，且位于同一侧。
作为本发明的一种优选实施方式，所述第二出水口6的排水扬程小于第一出水口2的排水扬程。具体地，所述的第二出水口6的排水扬程为0.2m-0.8m，这样更适合于将重用水在水重用系统中进行有效的过滤处理。
作为本发明的一种优选实施方式，所述的第一出水口2、第二出水口6上分别设置第一止逆结构3、第二止逆结构7，第二止逆结构7采用软质材料一体成型，包括呈圆环状的安装部703和呈圆盘状的止逆部701，安装部703套装在第二出水口6的管壁上，止逆部701盖在第二出水口6上。
本发明的双头排水泵的两个出水口处均设有止逆结构，可以防止水回流，避免二次污染。
由于第二出水口6的排水扬程较小，因此，第二排水口6的内径也较小，本发明根据第二出水口6的这一结构特点设计出了一种结构简单且的第二止逆结构7。如图8所示，第二止逆结构7采用软质材料一体成型，包括安装部703、止逆部701和将二者连接成一体的连接柱702，所述的安装部703套装在第二出水口6的管壁上，自然状态下，止逆部701盖在第二出水口6上，当有水流从第二出水口6流出时，止逆部701在水流作用下被打开，而反向水流将会将止逆部701更加紧密的盖在第二出水口6上，从而实现了第二出水口6只能单向排出，而不会反向流回至第二泵壳9内，从而实现止逆的作用。因此，本发明的第二止逆结构7的结构更加的简单，安装更加的方便，且止逆效果明显。
实施例一
如图1、图2、图3、图4、图9、图10及图11所示，本实施例为适用于一种洗衣机双头排水泵的加强连接件，所述的双头排水泵包括共用一个进水口8的至少两个排水泵，所述的双头排水泵的两个排水泵通过加强连接件11连接为一体，加强连接件11固定安装在洗衣机安装板12上。
由于双头排水泵的两个排水泵的结构不同，因此会造成双头排水泵受力不均衡，所以容易产生震动，如果两个排水泵的连接不够牢固在震动过程中容易损坏，因此，本实施例 的加强连接件11针对双头排水泵的结构特点，可牢固的将两个排水泵固定连接起来，并通过加强连接件11固定安装在洗衣机安装板12上，确保其安装的稳定性。
由于本实施例的加强连接件11是为了将双头排水泵的两个排水泵连接为一体，因此，本实施例所述的加强连接件11包括两个分别用于安装两个排水泵的安装部，所述的两个安装部在双头排水泵的轴向上前后交错设置，使得两个排水泵在轴向上前后交错设置。
本实施例的加强连接件11包括两个安装部，两安装部在泵壳轴向上具有前后的错位，以实现轴向空间换径向空间。具体地，由于泵壳上设有连接排水电机的泵壳连接部，泵壳连接部的径向尺寸一般较大以确保排水电机的安装稳定性，两泵壳连接部同时通过固定连接件11连接为一体并安装在洗衣机安装板12上。若两个泵壳连接部在同一径向端面，则需要增加两者在径向上的安装距离，而加强连接件11的两安装部在泵体轴向上具有前后的错位设置，使得两泵壳连接部在轴向上前后错位安装，两泵壳连接部相邻部分可在轴向重合，节约在同一径向端面上的安装距离。
如图9、图10及图11所示，所述的加强连接件包括第一连接部1102、第二连接部1104以及连接部1105，第一连接部1102与第二连接部1104在双头排水泵的轴向上前后交错设置，连接部1105设置在第一连接部1102和第二连接部1104之间将两者连成一体。
本实施例的第一连接部1102与双头排水泵的一个排水泵相连，第二连接部1104则与另外一个排水泵相连，两者前后交错设置并且通过连接部1105连接为一体，这样，双头排水泵的两个排水泵通过加强连接件11连接为一体，且实现了前后交错设置，节省了径向上的安装空间。
本实施例的第一连接部1102上设置有用于与双头排水泵相连接的第一安装孔1101，第二连接部1104上设置有用于与双头排水泵相连接的第二安装孔1103，可采用螺栓或者螺钉进行固定安装，安装方式更加的简单方便。
本实施例的加强连接件11通过固定安装在洗衣机安装板12上，以实现将双头排水泵固定安装在洗衣机安装板12上，具体地，所述的第一连接部1102和第二连接部1104的下部部分分别向下延伸形成用于安装在洗衣机安装板12上的第一支撑安装部1110和第二支撑安装部1108。
本实施例的加强连接件11在对应的连接部下部都设置与洗衣机安装板12相连接的支撑安装部，使得加强连接件11受到多点支撑作用，进而确保了双头排水泵的安装稳定性。
具体地，为了将本实施例的加强连接件11固定安装在洗衣机安装板12上，所述的第一支撑安装部1110和第二支撑安装部1108上沿着其垂直方向设置至少两个支撑安装脚 1109，两个支撑安装脚1109之间形成用于卡装在洗衣机安装板12上的安装卡位1106。
本实施例采用将两个支撑安装脚1109之间形成的安装卡位1106卡装在洗衣机安装板12上的方式实现加强连接件11的固定安装，与之对应地，在洗衣机安装板12上上设置安装孔，第一支撑安装部1110和第二支撑安装部1108分别深入到与之相对应的安装孔内，两个支撑安装脚1109卡装在洗衣机安装板12上，因此，本实施例的加强连接件11的安装方式更加的简单方便。另外，在两个支撑安装脚1109上可套装上减震垫，从而实现对双头排水泵的减震作用，降低使用过程中的噪音。
为了进一步的增大加强连接件11对双头排水泵的支撑作用，本实施例的加强连接件11的第一连接部1102和支撑部1107沿着其垂直方向延伸分别形成两个支撑筋1111，所述的支撑筋1111均支撑在洗衣机安装板12的上表面。通过支撑筋1111的支撑作用，可进一步增强其支撑稳定性。
进一步地，所述的支撑筋1111平行于支撑安装脚1109设置，支撑筋1111与支撑安装脚1109设置在加强连接件11的同一侧，或者分别设置在两侧。优选地，支撑筋1111与支撑安装脚1109分别设置在加强连接件11的两侧，这样可以使加强连接件两侧都能得到有效的支撑作用。
为了进一步的减小泵壳径向上的长度，所述的两个排水电机的安装方向相垂直，因此，本实施例的加强连接件11的第一连接部1102横向设置，第二连接部1104竖向设置，所述的第二连接部1104的一侧部分横向延伸形成支撑部1107，支撑部1107与第一连接部1102反向设置。由于本实施例的第二连接部1104竖向设置，双头排水泵连接后对该处的支撑不够或者不好，因此本实施例的第二连接部1104的一侧部分横向延伸形成支撑部1107，支撑部1107可进一步的对其进行支撑，确保其整体安装稳定性。
本实施例所述的加强连接件11为一体冲压的钣金构件，这样使得加强连接件11的一体性更强，连接稳定效果更好。
具体地，本实施例所述双头排水泵的两个排水泵分别包括第一泵壳4和第二泵壳9，第一泵壳4和第二泵壳9内部相互连通，所述的进水口8设置在第一泵壳4上；所述的加强连接件包括两个分别用于安装第一泵壳4和第二泵壳9的安装部。
进一步地，所述的第一泵壳4和第二泵壳9并列设置，第一泵壳4和第二泵壳9的一端端部分别设置第一泵壳安装部和第二泵壳安装部，所述的第一泵壳安装部和第二泵壳安装部分别安装第一排水电机1和第二排水电机10；所述的加强连接件的两个安装部分别连接第一泵壳安装部和第二泵壳安装部，使得第一泵壳安装部和第二泵壳安装部在轴向上交 错设置。
本实施例的加强连接件11和第一排水电机1、第二排水电机10均连接在泵壳安装部上，因此，两者可共用一个安装孔位，不需要再单独开设孔位，安装更加的简单。
本实施例所述双头排水泵包括泵壳，泵壳上设置进水口8、至少一个第一出水口2和至少一个第二出水口6，泵壳上对应第一出水口2安装有控制其开启/关闭的第一排水电机1，泵壳上对应第二出水口6安装有控制其开启/关闭的第二排水电机10；所述的加强连接件将第一排水电机1和第二排水电机10连接为一体。
实施例二
如图1、图4、图9、图12、图13、图14及图15所示，本实施例为适用于一种洗衣机双头排水泵的安装减震装置，所述的双头排水泵包括共用一个进水口8的至少两个排水泵，两个排水泵通过加强连接件连接为一体，加强连接件安装在洗衣机安装板12上，所述的加强连接件和洗衣机安装板12之间设置用于缓解双头排水泵震动的安装减震装置14。
由于双头排水泵包括两个结构不同的排水泵，两个排水泵通过一个加强连接件11连接为一体，并通过加强连接件11固定安装在洗衣机安装板12上，由于双头排水泵工作过程中两个排水泵受力不均衡，所以容易产生振动及噪音，而且容易损坏，因此，本实施例的安装减震装置14设置在加强连接件11和洗衣机安装板12之间，可有效缓解双头排水泵震动以及噪音。
由于本实施例的安装减震装置14设置在加强连接件11和洗衣机安装板12之间，因此，安装减震装置14需要既与加强连接件11相装配，又与和洗衣机安装板12想装配，安装减震装置14相对于加强连接件11和洗衣机安装板12均具有减震作用。作为本实施例所述的安装减震装置包括采用弹性软质材料制成的本体，本体上设有用于装配洗衣机安装板12的第一减震腔室1404，和用于装配加强连接件的第二减震腔室。
如图12、图13、图14及图15所示，本实施例所述的本体为槽型结构，槽型结构的中部具有槽口，槽口卡装在洗衣机安装板12上，所述的第一减震腔室1404为槽型结构的槽口。
进一步地，所述的槽口处设有斜角，槽口的上壁和下壁上分别对应设置多个凸起筋位1407。本实施例的槽口处设有斜角，便于安装。本实施例的槽口上壁和下壁分别对应设置条状凸起筋位，装配后凸起筋位与洗衣机安装板接触，起到减震作用，且能避免共振。
本实施例所述的第一减震腔室1404将本体分成相互连接的第一减震部1401和第二减震部1402，所述的第二减震腔室设置在第一减震部1401和/或第二减震部1402上。
进一步地，所述的第二减震腔室为设置在第一减震部1401和/或第二减震部1402内部的空腔，该空腔朝着第一减震部401和/或第二减震部1402的一侧开设开口，且该开口与第一减震腔室1404的开口方向相反。这主要是由于本实施例的安装减震装置14的一侧安装在洗衣机安装板12上，另一侧安装加强连接件11。
具体地，槽型结构的上端即为第一减震部1401，槽型结构的下端即为第二减震部1402，槽型结构的上端和下端的后方内部分别设有两个安装槽，安装槽即为第二减震腔室。
本实施例所述的本体上设置用于限位固定加强连接件的卡扣1403，卡扣1403对称设置在第二减震腔室两侧。
本实施例的安装减震装置，其外形为槽型结构，槽型结构上下端长度可以不同，可上长下短，第一减震腔室为槽型结构的槽口，槽口处设有斜角，便于安装；槽型结构的上下端后方内部分别设有两个安装槽，第二减震腔室为安装槽。安装槽两侧设有卡扣，防止安装减震装置在装配过程中脱落或者组装后在运输过程中脱落。槽口上壁和下壁分别对应设置条状凸起筋位，装配后凸起筋位与洗衣机安装板接触，起到减震作用，且能避免共振。
本实施例的安装减震装置的槽型结构从洗衣安装板上的安装孔处装配，槽型结构的槽口卡在洗衣安装板上下方，可以起到上下减震的作用，并可以起到限位功能。
为了节省原材料，本实施例设置壁厚不同，与洗衣安装板接触的面厚度较大，增加减震效果，其余较小。
本实施例所述的加强连接件下部用于安装在洗衣机安装板12上的支撑安装部，支撑安装部上设有定位支撑在洗衣机安装板12上的支撑安装脚；支撑安装脚上设有安装减震装置。
具体地，所述的加强连接件包括两个分别用于安装两个排水泵的安装部，两个安装部下部部分分别向下延伸形成第一支撑安装部1110和第二支撑安装部1108，所述的安装减震装置分别安装在第一支撑安装部1110和第二支撑安装部1108上。
进一步地，所述的第一支撑安装部1110和第二支撑安装部1108上沿着其垂直方向设置至少两个支撑安装脚1109，所述的支撑安装脚1109分别安装在两个第二减震腔室中，所述的第一支撑安装部1110和第二支撑安装部1108限位安装在两个卡扣1403之间。
本实施例的第一支撑安装部1110和第二支撑安装部1108上分别设置至少两个支撑安装脚1109，与之相应的，所述的第二减震腔室包括第二减震上腔室1405和第二减震下腔室1406，以实现与支撑安装脚1109的装配。
本实施例的支撑安装脚1109根据加强连接件11的具体结构以及安装在洗衣机的安装板12的安装方式，在本体上分别设置与洗衣机安装板12相装配的第一减震腔室1404，和装配加强连接件11的支撑安装脚1109的第二腔室，使得本实施例的加强连接件11与洗衣 机安装板12之间不直接接触，而是通过支撑安装脚1109固定连接起来，可有效的减少双头排水泵工作过程中加强连接件11与洗衣机安装板12之间的震动和噪音，使用户获得更好的用户体验。
实施例三
如图1、图3、图4、图5、图6及图7所示，本实施例为适用于一种洗衣机双头排水泵的过滤器，所述的双头排水泵包括泵壳，泵壳上设置进水口及共用进水口的至少两个出水口，两个出水口分别由两个排水电机控制其开启/关闭，所述的泵壳内部两个出水口与进水口之间设置过滤器13，所述的过滤器13包括至少两个分别对应两个出水口的出水部，至少一个出水部上设置过滤部。
本实施例的过滤器13设置在双头排水泵的泵壳内部且位于两个出水口与进水口之间，使得洗衣机的排水经其过滤后分别从两个出水口排出。本实施例的过滤器13可将排水中的线屑及杂物过滤，以防止其堵塞出水口。
另外，由于本实施例的两个出水口的排水作用不同，可根据具体的设计需要只在两个出水部中的一个上设置过滤部，在满足过滤要求的基础上，简化了过滤器的结构，降低了制造成本。
本实施例所述的过滤器包括框状本体1305，框状本体1305两侧边框之间分别设置进水部1301、第二出水部1302，框状本体1305位于泵壳内部的一端端部设置第一出水部1303。
本实施例的第一出水部1303的排水直接排出洗衣机，因此，不需要对排水进行很大程度的过滤，只需要将排水中的线屑及杂物过滤掉即可，而且过度的过滤会影响到第一出水部1303的排水速度，因此本实施例的第一出水部1303直接与进水部1301连通。
进一步地，本实施例的第一出水部1303上设置十字型筋位，用以过滤掉排水中的线屑和杂物，防止堵塞与第一出水部1303对应的出水口。
作为本实施例的一种优选实施方式，所述的框状本体1305位于泵壳内部的一端端部为封闭底座1310，封闭底座1310呈圆盘状设置，且与泵壳内壁接触，所述的第一出水部1303为设置在封闭底座1310凸台状出水口。
本实施例的第二出水部1302对应的出水口的排水将通向洗衣机的水重用系统，水重用系统将排水进行过滤净化后重新进行利用，因此，对从第二出水部1302排出的水的过滤程度要求较高，需要在第二出水部1302上设置顾虑程度较高的过滤部，以最大程度的过滤掉线屑或者杂物。
作为本实施例的一种优选实施方式，本实施例的第二出水部1302与泵壳之间封闭接触， 所述的第二出水部1302上设置过滤部。
如图6及图7所示，具体地，所述的第二出水部1302包括底壁1308和分别与底壁1308相连接的第一侧壁1306、第二侧壁1307，底壁1308连接框状本体1305两侧边框，所述的底壁1308、第一侧壁1306、第二侧壁1307和泵壳内壁之间形成出水腔室，出水腔室分别连通一个出水口和进水口。
进一步地，所述的底壁1308上设置多个进水孔1309以形成过滤部，所述的第一侧壁1306、第二侧壁1307分别与底壁1308一侧的泵壳内壁之间封闭接触，使得水流只能从过滤部进入出水腔室。
本实施例的进水孔1309的孔径较小，以最大程度的对排水进行过滤，同时进水孔109设置的数量较多，以确保达到与第二出水部1302对应的排水口的排水扬程。
进一步地，所述的底壁1308的一侧朝向第一出水部1303所在的端部延伸并与其连接，所述的第一侧壁1306沿着底壁1308该侧设置并与其连接。
这样一方面可增大底壁1308的面积，同时增大第二出水部1302的过滤面，增大其进水量，另一面使得底壁1308与框状本体1305三面连接，更加稳固。
由于本实施例的第一出水部1303、第二出水部1302必须与两个出水口相对应，不然从第二出水部1302排出的水就无法实现过滤效果，因此，作为本实施例的一种优选实施方式，本实施例所述的框状本体1305的至少一侧边框上设置限位块1306，泵壳的内壁上设置限位滑槽，所述的限位块1306沿着限位滑槽滑进泵壳内部，使得过滤器的两个出水部分别与双头排水泵的两个出水口对应安装。
同时，由于现有的过滤器都是通过螺纹安装的方式装入泵壳内部的，而将过滤器13的限位块1306限定在泵壳的滑槽内后，过滤器13便无法转动，也就不能进行螺纹安装，因为，为了将本实施例的过滤器13装入到泵体内部，而不改变其螺纹安装的方式，作为本实施例的一种优选实施方式，本实施例所述的框状本体1305的另一端部连接有可自由转动的过滤器安装部1304，过滤器安装部1304固定安装在泵壳上，所述的第二出水部1302与过滤器安装部1304之间形成进水部1301。
具体地，框状本体1305的另一端部上设置一颈部，所述的过滤器安装部1304卡装在颈部内且能自由转动即可。
作为本实施例的一种优选实施方式，所述的泵壳至少包括内部相互连通的第一泵壳4和第二泵壳9，所述的进水口8、第一出水口2分别设置在第一泵壳4上，第二出水口6设置在第二泵壳9上；所述的过滤器安装在第一泵壳4的内部腔室，过滤器的一个出水部对 应第一出水口2设置，另一个对应第一泵壳4与第二泵壳9的连接处设置。
具体地，所述的第一泵壳4上还设有与进水口8连通的第三出水口，所述的第二泵壳9连接第三出水口；所述的第一出水部1303对应第一出水口2设置，第二出水部1302对应第三出水口设置。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
