It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any way.
[0027] The liner assembly provided in the embodiment of the present application is as follows: Figures 2 to 6 As shown, it includes: an inner tank; a water inlet pipe 200, which is sealed and penetrates the bottom wall 100 of the inner tank, the upper end of the water inlet pipe 200 is located inside the inner tank and is provided with a water outlet 210, and the lower end of the water inlet pipe 200 is located outside the inner tank and is provided with a water inlet; and a water stop cap 300, the water stop cap 300 is located inside the inner tank and covers the upper end of the water inlet pipe 200, and the water stop cap 300 is configured to prevent water flowing out of the water outlet 210 from flowing upward (upward can be inclined upward or vertically upward).
[0028] The inner container assembly, cold water from the water inlet pipe 200 into the inner container, the water cap 300 prevents the cold water from the water outlet 210 from flowing upwards, so that the cold water from the water outlet 210 reduces the impact of the temperature stratification of the hot water above the water outlet 210 in the inner container, so that the upper part of the water outlet 210 in the inner container is less likely to mix cold and hot water, so the output rate of the hot water in the inner container is higher. Moreover, the water cap 300 is covered on the upper end of the water inlet pipe 200, and the assembly scheme of the water cap 300 and the water inlet pipe 200 is relatively simple.
[0029] It can be that the water cap 300 and the water inlet pipe 200 are provided in an integrated structure; or it can be that the water cap 300 and the water inlet pipe 200 are provided in a split structure, as shown in Figure 2 、 Figure 4 and Figure 5 , and the like; all of the above can achieve the purpose of the present application, and the design idea is not deviated from the design idea of the present application, and will not be described here, and all should be within the protection scope of the present application.
[0030] In some examples, as shown in Figure 2 、 Figure 4 and Figure 5 , the water cap 300 and the water inlet pipe 200 are provided in a split structure and are connected by clamping, so that the water cap 300 and the water inlet pipe 200 are relatively easy to manufacture, and the assembly efficiency of the water cap 300 and the water inlet pipe 200 is also relatively high.
[0031] In some embodiments, as shown in Figure 4 and Figure 5 , one of the water cap 300 and the water inlet pipe 200 is provided with a clamping hole 310, and the other is provided with an elastic clamping jaw 220, and the elastic clamping jaw 220 is clamped into the clamping hole 310 to achieve clamping connection of the water cap 300 and the water inlet pipe 200. Among them, the elastic clamping jaw 220 includes a plurality of circumferentially distributed elastic clamping jaws 220, and the plurality of elastic clamping jaws 220 are clamped into the clamping hole 310 together to achieve clamping connection of the water cap 300 and the water inlet pipe 200.
[0032] It can be that, as shown in Figure 4 and Figure 5 , the water cap 300 is provided with a clamping hole 310, and the water inlet pipe 200 is provided with an elastic clamping jaw 220; or it can be that the water cap 300 is provided with an elastic clamping jaw, and the water inlet pipe 200 is provided with a clamping hole; of course, as shown in Figure 6 , the water cap 300 and the water inlet pipe 200 are connected by a screw 400 and the like; all of the above can achieve the purpose of the present application, and the design idea is not deviated from the design idea of the present application, and will not be described here, and all should be within the protection scope of the present application.
[0033] In some examples, as shown in Figures 2 to 5As shown, the cap mouth of the water blocking cap faces the bottom wall 100 of the inner container, and the water outlet 210 is located inside the water blocking cap and is arranged on the peripheral wall of the water inlet pipe 200 (i.e., the water outlet 210 faces the inner surface of the water blocking cap). The cold water flowing out of the water outlet 210 impacts on the inner surface of the water blocking cap, and the inner surface of the water blocking cap guides the cold water to flow from the cap mouth of the water blocking cap towards the bottom wall 100 of the inner container (i.e., the cold water flows obliquely or vertically from the cap mouth of the water blocking cap towards the bottom wall 100 of the inner container), so as to reduce the cold water impacting on the hot water above the water outlet 210 in the inner container, and thus the cold water and the hot water above the water outlet 210 in the inner container are less likely to mix, and thus the output rate of the hot water in the inner container is higher.
[0034] In some embodiments, as shown in Figure 2 As shown, the bottom wall 100 of the inner container is provided with a low-lying place 110, the water blocking cap deviates from the low-lying place 110, and the distance between the water blocking cap and the bottom wall 100 of the inner container gradually increases from the position away from the low-lying place 110 to the position close to the low-lying place 110, so that the cold water flows from the cap mouth of the water blocking cap towards the low-lying place 110 under the guidance of the water blocking cap, and the outflow height of the cold water is lower, and the outflow disturbance of the cold water at the low-lying place 110 is smaller, so that the cold water impacts on the hot water above the water outlet 210 in the inner container is smaller, and thus the cold water destroys the temperature stratification of the hot water above the water outlet 210 in the inner container is smaller.
[0035] In some embodiments, as shown in Figure 2 As shown, the bottom wall 100 of the inner container is an arc-shaped wall, the concave side of the arc-shaped wall faces upwards, and the convex side faces downwards, and the low-lying place 110 is located at the center of the arc-shaped wall, and the lower end of the water blocking cap extends obliquely downwards from the position away from the center of the arc-shaped wall (i.e., away from the low-lying place 110) to the position close to the center of the arc-shaped wall (i.e., close to the low-lying place 110), so that the cold water flows obliquely downwards towards the low-lying place 110 under the guidance of the water blocking cap, and thus the outflow height of the cold water is further reduced, and thus the cold water impacts on the hot water above the water outlet 210 in the inner container is smaller.
[0036] In some embodiments, as shown in Figure 2 As shown, the distance between the end of the water blocking cap away from the low-lying place 110 and the bottom wall 100 of the inner container is not greater than 1 mm, and the distance between the end of the water blocking cap close to the low-lying place 110 and the bottom wall 100 of the inner container is not greater than 6 mm (preferably 4-6 mm), so that the cold water impacts on the hot water above the water outlet 210 in the inner container is smaller, and thus the output rate of the hot water in the inner container is higher.
[0037] In some embodiments, as shown in Figures 2 to 5As shown, the water-blocking cap includes: a cap body 320, which is capped on the upper end of the water inlet pipe 200, and the cap mouth of the cap body 320 faces the bottom wall 100 of the inner container, and the water outlet 210 is located inside the cap body 320; and a cap brim 330, which is located on one side of the cap body 320 near the low-lying place 110 and is connected with the mouth wall of the cap mouth of the cap body 320. The cap body 320 guides the cold water to flow downward, and the cap brim 330 guides the cold water to flow obliquely downward toward the low-lying place 110. That is, the cold water flowing out of the water outlet 210 first flows downward under the guidance of the cap body 320, and then flows obliquely downward toward the low-lying place 110 (the low-lying place 110 is the center of the arc-shaped wall) under the guidance of the cap brim 330.
[0038] In some embodiments, the inner container includes a lower head and a peripheral wall of the inner container, the arc-shaped wall is located on the lower head, and the peripheral wall of the inner container is a cylindrical ring structure, and the periphery of the lower head is sealingly connected (such as welded connection) with the lower end of the peripheral wall of the inner container.
[0039] In some embodiments, as shown in Figure 2 、 Figure 4 and Figure 5 , the water outlet 210 is arranged as a plurality of rectangular holes uniformly arranged on the upper end of the peripheral wall of the water inlet pipe 200.
[0040] The water tank (not shown in the figure) provided by the embodiments of the present application includes the inner container assembly described in any of the above embodiments.

[0043] The heat pump water heater has all the advantages of the water tank provided by any of the above embodiments, which will not be repeated here.
[0044] In summary, the technical scheme provided by the embodiments of the present application is that the cold water is supplied into the inner container from the water inlet pipe, and the water-blocking cap prevents the cold water flowing out of the water outlet from flowing upward, so that the impact of the cold water flowing out of the water outlet on the temperature stratification of the hot water above the water outlet in the inner container is reduced, and therefore the cold-hot water mixing is less likely to occur above the water outlet in the inner container, and therefore the output rate of the hot water in the inner container is higher. Moreover, the water-blocking cap is capped on the upper end of the water inlet pipe, and the assembly scheme of the water-blocking cap and the water inlet pipe is relatively simple.
