Technical Field
[0001] The present application belongs to the technical field of household electrical appliances, and specifically relates to a water treatment device. Background Art
[0002] The shell of the water treatment equipment is provided with a water inlet, a water outlet, and a water inlet valve connected to the water inlet and a water outlet valve connected to the water outlet. The water inlet interface of the existing water inlet valve is built into the interior of the shell. In order to achieve the docking connection between the water inlet valve and the water inlet, it is necessary to add a water inlet pipe connector to the shell. One end of the water inlet pipe connector passes through the water inlet to extend into the interior of the shell to achieve the connection with the water inlet interface of the water inlet valve. The water outlet interface of the existing water outlet valve is also built into the interior of the shell. In order to achieve the docking connection between the water outlet valve and the water outlet, it is necessary to add a water outlet pipe connector to the shell. One end of the water outlet pipe connector passes through the water outlet to extend into the interior of the shell to achieve the connection with the water outlet interface of the water outlet valve.
[0003] Therefore, in the prior art, the connection position of the water inlet pipe connector and the water inlet valve, and the connection position of the water outlet pipe connector and the water outlet valve are both located inside the housing.

Moreover, the addition of the pipe connector not only increases the cost of the whole machine, but also increases the assembly process, reducing the assembly efficiency of the whole machine.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:
[0018] 1. In the present application, the water inlet end of the water inlet valve passes through the water inlet of the shell, and the water outlet end of the water outlet valve passes through the water outlet of the shell. On the one hand, it avoids adding a water inlet joint at the water inlet valve to connect with the water inlet to realize water inlet, and it also avoids adding a water outlet joint at the water outlet valve to connect with the water outlet to realize water outlet, thereby reducing the number of connecting parts, which not only reduces the cost, but also avoids the water leakage caused by the addition of connecting parts. On the other hand, the water inlet end passes through the water inlet, and the water outlet end passes through the water outlet. During the installation process of the water inlet valve and the water outlet valve, the rough positioning of the water inlet valve and the water outlet valve can be achieved through the water inlet and the water outlet, respectively, and the movement of the two along the radial direction of the water inlet and the water outlet is respectively restricted, thereby improving the assembly efficiency of the water inlet valve and the water outlet valve.
[0019] 2. As a preferred embodiment of the present application, the outer end face of the water inlet extends through the water inlet to the outside of the shell, and the outer end face of the water outlet extends through the water outlet to the outside of the shell, so that the joining position between the water inlet and the external pipeline and the joining position between the water outlet and the external pipeline are both located on the outside of the shell. Even if water leakage occurs at the joining position, the water drops will fall on the outside of the shell and will not affect the electronic components inside the shell, thereby reducing the protection cost of the electronic components inside the shell.
[0020] 3. As a preferred embodiment of the present application, the valve seat is provided with a first clamp for clamping the water inlet pipe connected to the water outlet valve to limit the displacement of the water outlet valve in a direction perpendicular to the axial direction of the water outlet, and the valve seat is provided with a second clamp for clamping the water outlet pipe connected to the water inlet valve to limit the displacement of the water inlet valve in a direction perpendicular to the axial direction of the water inlet. The first clamp and the second clamp respectively limit the displacement of the water outlet valve and the water inlet valve, and can respectively play a role in coarse positioning of the water outlet valve and the water inlet valve during the installation process of the water outlet valve and the water inlet valve, which helps to improve the assembly efficiency of the two. When the assembly is completed, the displacement restriction of the water outlet valve and the water inlet valve by the first clamp and the second clamp can ensure the installation position of the water outlet valve and the water inlet valve, avoid the eccentric arrangement of the water outlet valve and the water outlet, and the water inlet valve and the water inlet, thereby ensuring that the water inlet valve and the water outlet valve can be smoothly docked with the adapter located on the outside of the shell, respectively, greatly reducing the occurrence of water leakage. In addition, the first clamp and the second clamp are used to limit the water outlet valve and the water inlet valve, so that the water outlet valve and the water inlet valve can be easily installed and removed, making the installation, maintenance and repair work simple and easy.
[0021] 4. As a preferred embodiment of the present application, the valve seat is provided with a first supporting rib, which is against the water outlet valve; and / or, the valve seat is provided with a second supporting rib, which is against the water inlet valve. By providing the first supporting rib and the second supporting rib, the contact area between the water outlet valve and the water inlet valve and the valve seat can be reduced, thereby reducing the transmission path of the vibration generated during the operation of the water outlet valve and the water inlet valve, which can achieve a better effect of reducing vibration and noise. Moreover, the arrangement of the first supporting rib and the second supporting rib can enhance the structural strength of the valve seat, thereby enhancing the ability of the valve seat to resist deformation, and while enhancing the service life of the valve seat, can ensure the stability of the installation of the water inlet valve and the water outlet valve.
[0022] 5. As a preferred embodiment of the present application, the water outlet valve and the valve seat are connected by a first fastener penetrating the first mounting hole and the second mounting hole; and / or, the water inlet valve and the valve seat are connected by a second fastener penetrating the third mounting hole and the fourth mounting hole. The connection between the water outlet valve and the valve seat is achieved by the first fastener, and / or the connection between the water inlet valve and the valve seat is achieved by the second fastener, which can not only achieve rapid installation between the water outlet valve and the valve seat, and / or between the water inlet valve and the valve seat, but also facilitate subsequent maintenance and repair of the water outlet valve and / or the water inlet valve. In addition, the installation positions of the water outlet valve and the water inlet valve can be ensured to avoid displacement between the two.
[0023] 6. As a preferred embodiment of the present application, the control unit and the valve unit are separated on both sides of the valve seat, which not only realizes the dual use of the valve seat, but also realizes the relative isolation between the control unit and the water inlet valve and the water outlet valve through the valve seat, thereby realizing the separation of water and electricity and improving the protection effect of the control unit. Moreover, this embodiment makes full use of the space on the two opposite surfaces of the valve seat, making the layout of the whole machine more compact and contributing to the miniaturization of the whole machine.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
[0039] like Figures 1 to 4 As shown, a water treatment device includes a shell 1, a valve seat 4 arranged in the shell 1, and a valve unit installed on the valve seat 4, the valve unit includes an inlet valve 2 and an outlet valve 3, the shell 1 is provided with a water inlet 11 and a water outlet 12 penetrating the shell 1, the inlet valve 2 is provided with a water inlet end 21, the outlet valve 3 is provided with a water outlet end 31, the water inlet end 21 penetrates the water inlet 11, and the water outlet end 31 penetrates the water outlet 12.
[0040] The water inlet end 21 of the water inlet valve 2 in the present application refers to a structural component belonging to the water inlet valve 2 itself rather than an adapter connected to the water inlet valve 2 to constitute the water inlet end 21, and the water outlet end 31 of the water outlet valve 3 refers to a structural component belonging to the water outlet valve 3 itself rather than an adapter connected to the water outlet valve 3 to constitute the water outlet end 31.
[0041] In the present application, the water inlet end 21 of the water inlet valve 2 passes through the water inlet 11 of the shell 1, and the water outlet end 31 of the water outlet valve 3 passes through the water outlet 12 of the shell 1. On the one hand, it avoids adding a water inlet joint at the water inlet valve 2 to connect with the water inlet 11 to achieve water inlet, and it also avoids adding a water outlet joint at the water outlet valve 3 to connect with the water outlet 12 to achieve water outlet, thereby reducing the number of connecting parts, which not only reduces the cost, but also avoids the water leakage caused by the addition of connecting parts. On the other hand, the water inlet end 21 penetrates into the water inlet 11, and the water outlet end 31 penetrates into the water outlet 12. During the installation of the water inlet valve 2 and the water outlet valve 3, the rough positioning of the water inlet valve 2 and the water outlet valve 3 can be achieved through the water inlet 11 and the water outlet 12 respectively, and the movement of the two along the radial direction of the water inlet 11 and the water outlet 12 is respectively restricted, thereby improving the assembly efficiency of the water inlet valve 2 and the water outlet valve 3.
[0042] In the present application, the relative positional relationship between the water inlet end 21 and the water inlet 11, and the water outlet end 31 and the water outlet 12 may adopt any one of the following embodiments:
[0043] Embodiment 1: the water inlet end 21 of the water inlet valve 2 extends into the inner side of the water inlet 11 , and the water outlet end 31 of the water outlet valve 3 extends into the inner side of the water outlet 12 .
[0044] Embodiment 2: the water inlet end 21 of the water inlet valve 2 passes through the water inlet 11, and the outer end surface of the water inlet end 21 is flush with the outer side surface of the water inlet 11; the water outlet end 31 of the water outlet valve 3 passes through the water outlet 12, and the outer end surface of the water outlet end 31 is flush with the outer side surface of the water outlet 12.
[0045] Implementation method three: Figure 1 As shown, the outer end surface of the water inlet end 21 extends to the outside of the shell 1 through the water inlet 11, and the outer end surface of the water outlet end 31 extends to the outside of the shell 1 through the water outlet 12. Such an arrangement can make the joint position of the water inlet end 21 and the external pipeline and the joint position of the water outlet end 31 and the external pipeline both located on the outside of the shell 1. Even if water leakage occurs at the joint position, the water drops fall on the outside of the shell 1 and will not affect the electronic components inside the shell 1, thereby reducing the cost of protecting the electronic components inside the shell 1. In addition, the water inlet end 21 and the water outlet end 31 both pass through the outside of the shell 1, which can make the existence of the water inlet end 21 and the water outlet end 31 explicit, facilitate the connection of the water inlet end 21 and the water outlet end 31 with other pipelines respectively, and the connection part is located on the outside of the shell 1, thereby reducing the sealing cost.
[0046] The water treatment device in the present application also includes a water treatment unit arranged inside the shell 1, the water inlet valve 2 is provided with a water outlet pipe 23 connected to the water inlet of the water treatment unit, and the water outlet valve 3 is provided with a water inlet pipe 33 connected to the drain outlet of the water treatment unit.
[0047] It should be noted that the present application does not limit the function of the water treatment unit. In one embodiment, the water treatment unit is a filter unit, which includes a filter element, etc., to filter and purify the water entering the filter unit. In another embodiment, the water treatment unit is a heating unit, which includes a heating element, etc., to heat the water entering the heating unit. In another embodiment, the water treatment unit is an ice tank, which cools the water entering the ice tank.
[0048] As a preferred embodiment of the present application, Figure 2 and Figure 3As shown, the valve seat 4 is provided with a first clamp 41 and / or a second clamp 42, the water inlet pipe 33 is clamped into the first clamp 41 to limit the displacement of the water outlet valve 3 in a direction perpendicular to the axial direction of the water outlet 12, and the water outlet pipe 23 is clamped into the second clamp 42 to limit the displacement of the water inlet valve 2 in a direction perpendicular to the axial direction of the water inlet 11. The first clamp 41 and the second clamp 42 respectively limit the displacement of the water outlet valve 3 and the water inlet valve 2, and can respectively play a role in roughly positioning the water outlet valve 3 and the water inlet valve 2 during their installation, which helps to improve the assembly efficiency of the two. When the assembly is completed, the displacement restriction of the outlet valve 3 and the inlet valve 2 by the first clamp 41 and the second clamp 42 can ensure the installation position of the outlet valve 3 and the inlet valve 2, and avoid the eccentric arrangement of the outlet valve 3 and the water outlet 12, and the inlet valve 2 and the water inlet 11, thereby ensuring that the inlet valve 2 and the outlet valve 3 can be smoothly connected with the adapter located on the outside of the housing 1, respectively, greatly reducing the occurrence of water leakage. In addition, by limiting the outlet valve 3 and the inlet valve 2 through the first clamp 41 and the second clamp 42, the outlet valve 3 and the inlet valve 2 can be easily installed and disassembled, making the installation, maintenance and repair work simple and easy.
[0049] As a preferred embodiment of the present application, Figure 2 and Figure 3 As shown, the valve seat 4 is provided with a first limiting rib 46, and the first limiting rib 46 cooperates with the stopper of the water outlet valve 3 to limit the displacement of the water outlet valve 3 along a first direction perpendicular to the axial direction of the water outlet 12; and / or, the water inlet valve 2 and the water outlet valve 3 are arranged side by side on the valve seat 4 along a first direction perpendicular to the axial direction of the water outlet 12, and the valve seat 4 is provided with a second limiting rib 47, and the second limiting rib 47 cooperates with the stopper of the water inlet valve 2 to limit the displacement of the water inlet valve 2 along the first direction perpendicular to the axial direction of the water inlet 11. The first limiting rib 46 cooperates with the stopper of the water outlet valve 3 to limit the displacement of the water outlet valve 3 along the first direction. Therefore, the movement of the water outlet valve 3 along the first direction can be limited during the installation of the water outlet valve 3. On the one hand, the alignment between the water outlet valve 3 and the water outlet 12 can be conveniently and quickly achieved, so that the water outlet valve 3 can be quickly installed in place. On the other hand, the first limiting rib 46 can form a stopper for the water outlet valve 3 during the installation of the water outlet valve 3 to prevent it from moving along the first direction, thereby facilitating the fixation of the remaining installation parts of the water outlet valve 3 and improving the assembly efficiency. The second limiting rib 47 cooperates with the stopper of the water inlet valve 2 to limit the displacement of the water inlet valve 2 along the first direction. Therefore, the movement of the water inlet valve 2 along the first direction can be limited during the installation of the water inlet valve 2. On the one hand, the alignment between the water inlet valve 2 and the water inlet 11 can be conveniently and quickly achieved, so that the water inlet valve 2 can be quickly installed in place. On the other hand, the second limiting rib 47 can form a stopper for the water inlet valve 2 during the installation of the water inlet valve 2 to prevent it from moving along the first direction, thereby facilitating the fixation of the remaining installation parts of the water inlet valve 2 and improving the assembly efficiency.
[0050] In addition, the water inlet valve 2 and the water outlet valve 3 are arranged side by side on the valve seat 4 along a first direction perpendicular to the axial direction of the water outlet 12, which helps to compact the layout of the water inlet valve 2 and the water outlet valve 3 on the valve seat 4, thereby helping to miniaturize the entire machine.
[0051] As a preferred embodiment of this implementation, Figure 3 As shown, the first limiting rib 46 and the second limiting rib 47 extend in an arc shape respectively, which can adapt to the appearance of the water inlet valve 2 and the water outlet valve 3 on the one hand, and stop the water inlet valve 2 and the water outlet valve 3 respectively, and on the other hand, the stopping area between the water inlet valve 2 and the water outlet valve 3 can be increased as much as possible to improve the reliability of the stop.
[0052] As a preferred embodiment of the present application, Figure 2 and Figure 3 As shown, the valve seat 4 is provided with a first supporting rib 44, which is against the outlet valve 3; and / or, the valve seat 4 is provided with a second supporting rib 45, which is against the inlet valve 2. By providing the first supporting rib 44 and the second supporting rib 45, the contact area between the outlet valve 3 and the inlet valve 2 and the valve seat 4 can be reduced, thereby reducing the transmission path of the vibration generated during the operation of the outlet valve 3 and the inlet valve 2, and achieving a better vibration reduction and noise reduction effect. Moreover, the arrangement of the first supporting rib 44 and the second supporting rib 45 can improve the structural strength of the valve seat 4, thereby improving the ability of the valve seat 4 to resist deformation, and while improving the service life of the valve seat 4, it can ensure the stability of the installation of the inlet valve 2 and the outlet valve 3.
[0053] Furthermore, if Figure 3 As shown, the cross-sections of the first support rib 44 and the second support rib 45 along the first direction are both circular, which can increase the contact area between the first support rib 44 and the water outlet valve 3 and the contact area between the second support rib 45 and the water inlet valve 2 to achieve stable support, and can further reduce the contact area between the water outlet valve 3 and the water inlet valve 2 and the valve seat 4.
[0054] As a preference, Figure 3 As shown, there are two first limiting ribs 46 , which are respectively disposed on both sides of the first supporting rib 44 ; there are two second limiting ribs 47 , which are respectively disposed on both sides of the second supporting rib 45 .
[0055] As a preferred embodiment of the present application, Figure 2 and Figure 3As shown, the water outlet valve 3 is provided with a first mounting hole 32, the valve seat 4 is provided with a second mounting hole 48, and the water outlet valve 3 and the valve seat 4 are connected by a first fastener penetrating the first mounting hole 32 and the second mounting hole 48; and / or, the water inlet valve 2 is provided with a third mounting hole 22, the valve seat 4 is provided with a fourth mounting hole 49, and the water inlet valve 2 and the valve seat 4 are connected by a second fastener penetrating the third mounting hole 22 and the fourth mounting hole 49. The connection between the water outlet valve 3 and the valve seat 4 is achieved by the first fastener, and / or the connection between the water inlet valve 2 and the valve seat 4 is achieved by the second fastener, which can not only realize the rapid installation between the water outlet valve 3 and the valve seat 4, and / or between the water inlet valve 2 and the valve seat 4, but also facilitate the subsequent maintenance and repair of the water outlet valve 3 and / or the water inlet valve 2. In addition, the installation positions of the water outlet valve 3 and the water inlet valve 2 can be ensured to avoid the displacement of the two.
[0056] Furthermore, if Figure 2 As shown, the valve seat 4 is provided with a protruding first positioning frame 411, the water outlet valve 3 and the water inlet valve 2 are installed at the positioning frame, and the second mounting hole 48 and the fourth mounting hole 49 are located at two opposite corners of the diagonal of the positioning frame, so as to fully utilize the redundant space on the valve seat 4 to realize the installation of the water inlet valve 2 and the water outlet valve 3 and realize a compact structure arrangement.
[0057] As a preferred embodiment of the present application, Figures 2 to 4 As shown, one of the housing 1 and the valve seat 4 is provided with a buckle 13 , and the other is provided with a buckle position 43 adapted to the buckle 13 , and the valve seat 4 is connected to the housing 1 through the buckle 13 and the buckle position 43 .
[0058] As one of the examples under the present embodiment, the valve seat 4 and the shell 1 are connected only by the snap connection of the buckle 13 and the buckle position 43. Of course, there can be multiple buckles 13 and buckle positions 43. The valve seat 4 and the shell 1 are installed and fixed by the buckle 13 and the buckle position 43, which is convenient and fast, and realizes screw-free assembly, which helps to improve the assembly efficiency of the valve seat 4.
[0059] As another example of this implementation, Figure 3 and Figure 4 As shown, the housing 1 is provided with a positioning lug 14 for mounting the valve seat 4, the positioning lug 14 is provided with a fifth mounting hole 15, the valve seat 4 is provided with a sixth mounting hole 413, and the valve seat 4 is connected to the housing 1 via a third fastener penetrating the fifth mounting hole 15 and the sixth mounting hole 413. In this embodiment, the initial positioning between the valve seat 4 and the housing 1 is achieved through the buckle 13 and the buckle position 43, and the connection and fixation between the valve seat 4 and the housing 1 is achieved through the third fastener (such as a screw), which improves the stability of the valve seat 4 after installation, thereby ensuring the installation position of the water inlet valve 2 and the water outlet valve 3.
[0060] In this embodiment, the assembly between the valve seat 4 and the housing 1 can be any one of the following examples:
