DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0027] In this application, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0028] The present application embodiment provides a diverter plate, such as Figure 1 to Figure 7 As shown, the diverter plate includes a transverse partition 110, a first longitudinal partition 120 and a second longitudinal partition 130, and the first longitudinal partition 120 and the second longitudinal partition 130 are both arranged on the upper surface of the transverse partition 110; the first longitudinal partition 120 is arranged in a circle around the circumference of the transverse partition 110, and the second longitudinal partition 130 is arranged around the first longitudinal partition 120 to divide the upper space of the transverse partition 110 into a warm water zone 101, a variable temperature zone 102 and a cold water zone 103 arranged in sequence from the inside to the outside; the first longitudinal partition 120 is provided with a first water opening 121 connecting the warm water zone 101 and the variable temperature zone 102, and the second longitudinal partition 130 is provided with a second water opening 131 connecting the variable temperature zone 102 and the cold water zone 103.

[0029] Specifically, the first longitudinal partition 120 and the second longitudinal partition 130 are both cylindrical structures. The interior of the first longitudinal partition 120 defines a warm water zone 101, the variable temperature zone 102 is defined between the first longitudinal partition 120 and the second longitudinal partition 130, and the cold water zone 103 is defined between the second longitudinal partition 130 and the edge of the transverse partition 110; when the cold water in the cold water zone 103 is insufficient, the variable temperature zone 102 replenishes water to the cold water zone 103 through the second water port 131, and at the same time, the warm water zone 101 replenishes water to the variable temperature zone 102 through the first water port 121.

[0030] The diverter plate provided in the embodiment of the present application is configured such that the first longitudinal partition 120 and the second longitudinal partition 130 are arranged on the upper surface of the transverse partition 110, the first longitudinal partition 120 is arranged in a circle around the circumference of the transverse partition 110, and the second longitudinal partition 130 is arranged around the first longitudinal partition 120, so as to divide the upper space of the transverse partition 110 into a warm water zone 101, a variable temperature zone 102 and a cold water zone 103 which are arranged in sequence from the inside to the outside, the warm water zone 101 is connected with the variable temperature zone 102 through the first water opening 121 on the first longitudinal partition 120, and the variable temperature zone 102 is connected with the cold water zone 103 through the second water opening 131 on the second longitudinal partition 130, thereby the variable temperature zone 102 can be used to buffer the water flow, reduce the degree of mixing of cold water and warm water when the warm water is discharged, thereby reducing the influence of cold water on the outlet temperature of the warm water, ensuring the outlet temperature of the warm water, and avoiding the problem of the outlet temperature of the warm water being too low.

[0031] It can be understood that since the warm water zone 101 is adjacent to the variable temperature zone 102 but not to the cold water zone 103, the water in the warm water zone 101 directly exchanges heat with the water in the variable temperature zone 102. Also, since the temperature difference between the warm water zone 101 and the variable temperature zone 102 is much smaller than the temperature difference between the warm water zone 101 and the cold water zone 103, compared with the solution of direct heat exchange between the warm water zone and the cold water zone in the related art, in the present application, the heat exchange efficiency between the variable temperature zone 102 and the warm water zone 101 is worse, so that the adverse effect (i.e., cooling) on ​​the warm water zone 101 will be smaller, and the water temperature in the warm water zone 101 can be maintained at a higher temperature value to meet the user's usage requirements. Similarly, in the present application, since the cold water zone 103 is adjacent to the variable temperature zone 102 but not to the warm water zone 101, the water in the cold water zone 103 directly exchanges heat with the water in the variable temperature zone 102. Also, since the temperature difference between the cold water zone 103 and the variable temperature zone 102 is much smaller than the temperature difference between the warm water zone 101 and the cold water zone 103, compared with the direct heat exchange between the warm water zone and the cold water zone in the related art, the heat exchange efficiency between the warm water zone 101 and the cold water zone 103 in the present application is worse, so that the adverse effect (i.e., temperature rise) on the cold water zone 103 will be smaller, and the water temperature in the cold water zone 103 can be maintained at a lower temperature value to meet the user's usage requirements.

[0032] Optionally, the thermal conductivity of the diverter plate is lower than that of water, thereby reducing the heat conduction between the warm water zone 101 and the variable temperature zone 102, and between the variable temperature zone 102 and the cold water zone 103, and reducing the influence of cold water on the outlet temperature of the warm water, so as to ensure the outlet temperature of the warm water. Exemplarily, the diverter plate can be made of PP (polypropylene), and since the thermal conductivity of PP is much lower than that of water, PP can play a good heat insulation effect, reducing the heat conduction between the warm water zone 101 and the variable temperature zone 102, and between the variable temperature zone 102 and the cold water zone 103.

[0033] In some embodiments of the present application, the diverter plate further includes a first door body 140 for opening and closing the first water port 121, the first door body 140 is rotatably arranged around a horizontal axis to cover the first water port 121, and a first eccentric block 141 is provided at the lower end of the first door body 140; the first door body 140 is configured such that: when the buoyancy applied to the first door body 140 is less than the gravity, the first door body 140 opens the first water port 121 (such as Figure 5 to Figure 7 As shown), the water in the warm water zone 101 can flow to the variable temperature zone 102 through the first water port 121, so as to replenish the variable temperature zone 102 with water; when the buoyancy of the first door body 140 is greater than the gravity, the first door body 140 closes the first water port 121 (as shown in FIG. Figure 2 to Figure 4 As shown in FIG. 1 ), the water in the warm water zone 101 cannot flow to the variable temperature zone 102. By setting the first door body 140 of the above structure, the warm water zone 101 forms a closed warm water zone 101 without replenishing water to the variable temperature zone 102, thereby reducing the heat exchange between the warm water and the cold water and ensuring the outlet water temperature of the warm water.

[0034] Optionally, at least one side of the first water passage 121 is provided with a first limiting portion 122, the first door body 140 is located on the inner side of the first limiting portion 122, and the first eccentric block 141 is provided on the outward side of the first door body 140; when the first door body 140 closes the first water passage 121, the first door body 140 can abut against the first limiting portion 122. By adopting the above structure, the first limiting portion 122 can limit the first door body 140 when the first door body 140 closes the first water passage 121, so that the lower end of the first door body 140 cannot continue to rotate outward, thereby effectively closing the first water passage 121 to form a closed warm water area 101, thereby reducing the heat exchange between warm water and cold water.

[0035] In some embodiments of the present application, the diverter plate further includes a second door body 150 for opening and closing the second water port 131, the second door body 150 is rotatably arranged around a horizontal axis to cover the second water port 131, and a second eccentric block 151 is provided at the lower end of the second door body 150; the second door body 150 is configured such that: when the buoyancy applied to the second door body 150 is less than the gravity, the second door body 150 opens the second water port 131 (such as Figure 5 to Figure 7 As shown), the water in the variable temperature zone 102 can flow to the cold water zone 103 through the second water port 131 to replenish the cold water zone 103; when the buoyancy of the second door body 150 is greater than the gravity, the second door body 150 closes the second water port 131 (as shown). Figure 2 to Figure 4 As shown in FIG. 1 ), the water in the variable temperature zone 102 cannot flow to the cold water zone 103. By setting the second door body 150 of the above structure, the variable temperature zone 102 forms a closed variable temperature zone 102 without replenishing water to the cold water zone 103, thereby reducing the heat exchange between warm water and cold water and ensuring the outlet water temperature of the warm water.

[0036] Optionally, at least one side of the second water opening 131 is provided with a second limiting portion 132, the second door body 150 is located on the inner side of the second limiting portion 132, and the second eccentric block 151 is provided on the outward side of the second door body 150; when the second door body 150 closes the second water opening 131, the second door body 150 can abut against the second limiting portion 132. By adopting the above structure, the second limiting portion 132 can limit the second door body 150 when the second door body 150 closes the second water opening 131, so that the lower end of the second door body 150 cannot continue to rotate outward, thereby effectively closing the second water opening 131 to form a closed temperature change zone 102, thereby reducing the heat exchange between warm water and cold water.

[0037] In some embodiments of the present application, the first longitudinal baffle 120 is provided with two first guide plates 123 extending outward on both sides of the first water outlet 121, and the first guide plates 123 are suitable for guiding the water flow in the warm water zone 101 to the variable temperature zone 102, that is, the first guide plates 123 can play a guiding role, and smoothly guide the water flow in the warm water zone 101 to the variable temperature zone 102. Optionally, the distance between the two first guide plates 123 gradually increases from the first longitudinal baffle 120 to the outside, so that the water flow in the warm water zone 101 can be more smoothly guided to the variable temperature zone 102, and the guiding effect is better.

[0038] In some embodiments of the present application, the second longitudinal baffle 130 is provided with two second guide plates 133 extending outward on both sides of the second water outlet 131, and the second guide plates 133 are suitable for guiding the water flow in the variable temperature zone 102 to the cold water zone 103, that is, the second guide plates 133 can play a guiding role, and smoothly guide the water flow in the variable temperature zone 102 to the cold water zone 103. Optionally, the distance between the two second guide plates 133 gradually increases from the second longitudinal baffle 130 to the outside, so that the water flow in the variable temperature zone 102 can be more smoothly guided to the cold water zone 103, and the guiding effect is better.

[0039] In some embodiments of the present application, a guide hole 111 is provided at the bottom of the cold water zone 103, and the guide hole 111 can guide the water in the cold water zone 103 to the cold water cavity of the cold tank, thereby increasing the amount of cold water released. Optionally, the guide hole 111 is an inclined hole, and the inclined surface of the inclined hole can make the process of the water in the cold water zone 103 flowing to the cold water cavity of the cold tank smoother, further increasing the amount of cold water released.

[0040] Optionally, the diverter plate further includes a connecting pipe 160, which passes through the diaphragm 110 in the longitudinal direction and is connected to the warm water area 101. Specifically, one end of the connecting pipe 160 passes through the diaphragm 110 and is connected to the warm water area 101, and the other end of the connecting pipe 160 is suitable for connecting to the warm water outlet of the cold tank.

[0041] See also Figure 2 to Figure 7 , Figure 2 to Figure 7 The diverter disc shown works as follows:

[0042] When the water level in the cold water zone 103 drops, the buoyancy on the second door body 150 becomes smaller. Due to its own weight, the second door body 150 automatically opens the second water outlet 131 through the offset center of gravity, and the water in the variable temperature zone 102 is replenished to the cold water zone 103. At the same time, the water in the cold water zone 103 flows to the cold water chamber of the cold tank through the guide hole 111 for mixing; after the water level in the variable temperature zone 102 drops, the buoyancy on the first door body 140 becomes smaller. Due to its own weight, the first door body 140 automatically opens the first water outlet 121 through the offset center of gravity, and the warm water zone 101, the variable temperature zone 102 and the cold water zone 103 are connected. The water in the warm water zone 101 is replenished to the variable temperature zone 102, and the water in the variable temperature zone 102 is replenished to the cold water zone 103. After the cold water is replenished, the first door body 140 and the second door body 150 are closed by buoyancy.
