Description

Mixing tank and water heater containing it Technical Field

[0001] This utility model relates to a mixing tank and a water heater containing the same. Background Technology

[0002] Over time, tap water pipes accumulate a large amount of bacteria and impurities. These harmful substances can come into contact with human skin during bathing, potentially causing skin discomfort or even illness. Currently, water heaters commonly use silver ion sterilization technology to address this issue. However, the silver-plated filters used in existing technology have significant limitations. Due to their low silver ion density, the number of released silver ions is insufficient to achieve the ideal sterilization concentration. Moreover, the sterilization effect of silver ions is closely related to ion concentration; low concentrations of silver ions are insufficient to effectively inhibit bacterial growth, resulting in poor sterilization performance. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defect that the sterilization effect of water heaters in the prior art is difficult to guarantee, and to provide a mixing tank and a water heater containing the mixing tank.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A mixing tank, characterized in that it comprises:

[0006] The tank body has a cavity inside, and the cavity includes a first cavity and a second cavity that are connected along the axial direction of the tank body. The tank body has an inlet that communicates with the first cavity and an outlet that communicates with the second cavity.

[0007] The diverter includes a diverting baffle plate arranged radially along the tank body. The diverting baffle plate divides the cavity into a first cavity and a second cavity along the axial direction. The diverting baffle plate has a plurality of first diverting holes that penetrate along the axial direction, and the plurality of first diverting holes connect the first cavity and the second cavity.

[0008] A heating device is disposed in the flow divider plate and is used to heat the fluid located in the cavity.

[0009] In this technical solution, a heating device is set up to heat the fluid located in the cavity, thereby achieving the beneficial technical effect of high-temperature sterilization. Furthermore, the heating device is set in the flow divider that separates the first and second cavities, which can simultaneously heat the fluids in the first and second cavities located on both sides of the flow divider at the middle position of the cavity, thereby maximizing the heating efficiency of the heating device.

[0010] Preferably, the inlet and the outlet are respectively disposed on both sides of the diversion baffle along the axial direction;

[0011] The diverter also includes a diverter cylinder, which is located in the first cavity and is arranged along the axial direction. One end of the diverter cylinder is connected to the diverter baffle, and the other end extends toward the inlet. The diverter cylinder divides the first cavity radially into a first diverter zone within the diverter cylinder and a second diverter zone between the tank and the diverter cylinder. A plurality of second diverter holes are provided on the side wall of the diverter cylinder, which are radially penetrating and connect the first diverter zone and the second diverter zone.

[0012] In this technical solution, by setting up a diversion cylinder, the first cavity is divided into a first diversion zone inside the diversion cylinder and a second diversion zone between the tank and the diversion cylinder. The fluid entering the first cavity from the inlet first reaches the first diversion zone, and then passes radially through the second diversion hole before reaching the second diversion zone. This extends the flow path of the fluid, thereby increasing the time that the fluid stays in the first cavity for sterilization, and thus achieving a thorough sterilization effect.

[0013] Preferably, the diverter cylinder has a non-zero gap between itself and the inner wall of the tank along the axial direction.

[0014] In this technical solution, by setting a non-zero gap between the diversion cylinder and the inner wall of the tank along the axial direction, it is possible to guide the fluid that cannot pass through the second diversion hole when the fluid flow rate is too large, so that the fluid can directly enter the second diversion zone and avoid fluid backflow.

[0015] Preferably, the inner diameter of the diversion cylinder is larger than the diameter of the inlet.

[0016] In this technical solution, by setting the inner diameter of the diversion cylinder to be larger than the diameter of the inlet, sufficient space is provided to accommodate the fluid, so that the fluid can first enter the first diversion zone and then enter the second diversion zone through the second diversion hole.

[0017] Preferably, the plurality of second diversion holes are arranged in an array along the circumference of the diversion cylinder; and / or, the diameter of the second diversion holes is smaller than the diameter of the first diversion holes; and / or, the first diversion holes are arranged in an array.

[0018] In this technical solution, by arranging multiple second diversion holes in an array along the circumference of the diversion cylinder, a more uniform flow distribution effect can be achieved. By setting the diameter of the second diversion holes to be smaller than the diameter of the first diversion holes, the flow distribution effect can be further enhanced. Furthermore, by arranging the first diversion holes in an array, a more uniform flow distribution effect can be achieved.

[0019] Preferably, the inlet and the outlet are respectively disposed on both sides of the diversion baffle along the axial direction;

[0020] The mixing tank further includes a first guide cylinder and a second guide cylinder arranged along the axial direction, both of which are located in the second cavity;

[0021] One end of the first guide cylinder is connected to the diversion baffle, and the other end extends toward the outlet and is provided with a first opening toward the outlet.

[0022] One end of the second guide cylinder is connected to the bottom wall of the tank and communicates with the outlet, and the other end extends toward the diversion baffle and is provided with a second opening facing the diversion baffle.

[0023] The second guide cylinder is inserted into the first opening, and the gap between the outer wall of the second guide cylinder and the inner wall of the first guide cylinder forms a flow channel connecting the first opening and the second opening.

[0024] In this technical solution, the above-mentioned arrangement ensures that the fluid entering the second chamber first reaches the first opening near the outlet along the outer wall of the first tube, then changes direction and enters the first opening, then flows along the flow channel to the second opening near the diversion baffle, then changes direction and enters the second opening, then flows along the inner wall of the second cylinder to the outlet, thereby increasing the time the fluid stays in the second chamber for sterilization and further improving the sterilization efficiency.

[0025] Preferably, the length of the flow channel along the axial direction is 50%-80% of the length of the first guide cylinder.

[0026] In this technical solution, by setting the range of the length of the flow channel along the axial direction, on the one hand, the length of the flow channel is not too short, so that the fluid path is too short and the sterilization effect is not achieved; on the other hand, the length of the flow channel is not too long, so that the space between the end of the first guide cylinder near the diversion baffle and the second opening is too small, which affects the smooth flow of fluid from the first guide cylinder into the second opening of the second guide cylinder.

[0027] Preferably, the diversion baffle includes a first portion and a second portion connected along the axial direction, the first portion and the second portion surrounding and forming a receiving cavity that is separated from the cavity body;

[0028] The heating device has a disc-shaped structure, is located inside the accommodating cavity, and its outer periphery is in contact with the inner wall of the accommodating cavity.

[0029] In this technical solution, by setting a specific structure for the flow divider, a receiving cavity that is isolated from the main body can be provided for the heating device. Furthermore, by setting the heating device to a disc-shaped structure, with the heating device located inside the receiving cavity and the outer periphery of the heating device in contact with the inner wall of the receiving cavity, the heating device can achieve a better heating effect on the fluid in the cavity.

[0030] Preferably, the mixing tank further includes a temperature sensor disposed on the tank body, the temperature sensor being used to detect the temperature of the fluid inside the cavity.

[0031] A water heater characterized in that it includes a mixing tank as described above.

[0032] The positive and progressive effects of this utility model are as follows:

[0033] This invention achieves the beneficial technical effect of high-temperature sterilization by setting a heating device to heat the fluid located in the cavity; furthermore, by setting the heating device in the flow divider separating the first and second cavities, the fluids in the first and second cavities located on both sides of the flow divider can be heated simultaneously at the middle position of the cavity, thereby maximizing the heating efficiency of the heating device.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0072] As shown in Figures 1 to 5, this embodiment provides a mixing tank 1, which includes a tank body 10, a distributor 20, and a heating device 30.

[0073] The tank body 10 has a cavity inside, and the cavity includes a first cavity 11 and a second cavity 12 connected along the axial direction P of the tank body 10. The tank body 10 has an inlet 13 connected to the first cavity 11 and an outlet 14 connected to the second cavity 12.

[0074] The diverter 20 includes a diverter baffle 21, which is arranged radially R along the tank body 10. The diverter baffle 21 divides the cavity into a first cavity 11 and a second cavity 12 along the axial direction P. The diverter baffle 21 has a plurality of first diverter holes 211 that pass through along the axial direction P. The plurality of first diverter holes 211 connect the first cavity 11 and the second cavity 12.

[0075] The heating device 30 is located in the flow divider 21 and is used to heat the fluid located in the cavity.

[0076] In this way, by setting the heating device 30 to heat the fluid located in the cavity, the beneficial technical effect of high-temperature sterilization is achieved; furthermore, by setting the heating device 30 in the flow divider 21 that separates the first cavity 11 and the second cavity 12, the fluids in the first cavity 11 and the second cavity 12 located on both sides of the flow divider 21 can be heated simultaneously at the middle position of the cavity, so as to maximize the heating efficiency of the heating device 30.

[0077] Specifically, the tank body 10 is cylindrical, and the flow divider 21 is a shape that matches the cross-section of the tank body 10.

[0078] The inlet 13 and outlet 14 are respectively arranged on both sides of the diversion baffle 21 along the axial direction P. That is, the inlet 13 is located on the top wall 15 of the tank along the axial direction P; the outlet 14 is located on the bottom wall 16 of the tank along the axial direction P. Please refer to Figure 3.

[0079] The diverter 20 also includes a diverter cylinder 22, which is located in the first cavity 11 and is arranged along the axial direction P. One end of the diverter cylinder 22 is connected to the diverter baffle 21, and the other end extends towards the inlet 13. The diverter cylinder 22 divides the first cavity 11 radially into a first diverter zone 221 within the diverter cylinder 22 and a second diverter zone 222 between the tank 10 and the diverter cylinder 22. A plurality of second diverter holes 223 are provided on the side wall of the diverter cylinder 22, which are radially through the first diverter zone 221 and the second diverter zone 222.

[0080] In this way, by setting up the diversion cylinder 22, the first cavity 11 is divided into a first diversion zone 221 within the diversion cylinder 22 and a second diversion zone 222 between the tank 10 and the diversion cylinder 22. The fluid entering the first cavity 11 from the inlet 13 first reaches the first diversion zone 221, and then passes through the second diversion hole 223 radially R before reaching the second diversion zone 222 (the flow direction of the fluid is shown by the double arrows in Figure 4). This extends the flow path of the fluid, thereby increasing the time that the fluid stays in the first cavity 11 for sterilization, and thus achieving a thorough sterilization effect.

[0081] Preferably, a non-zero gap a is provided between the diversion cylinder 22 and the inner wall of the tank 10 along the axial direction P. In this way, by providing a non-zero gap a between the diversion cylinder 22 and the inner wall of the tank 10 along the axial direction P, the fluid that cannot pass through the second diversion hole 223 can be guided when the fluid flow rate is too large, so that the fluid can directly enter the second diversion zone 222 and avoid fluid backflow.

[0082] Preferably, the inner diameter d1 of the diversion cylinder 22 is larger than the diameter d2 of the inlet 13 to provide sufficient space to accommodate the fluid, so that the fluid can first enter the first diversion zone 221 and then enter the second diversion zone 222 through the second diversion hole 223.

[0083] Preferably, the plurality of second diversion holes 223 are arranged in an array along the circumference of the diversion cylinder 22 to achieve a more uniform diversion effect. The diameter of the second diversion holes 223 is smaller than the diameter of the first diversion holes 211 to better achieve the diversion effect. The first diversion holes 211 are arranged in an array to achieve a more uniform diversion effect.

[0084] Preferably, the mixing tank 1 further includes a first guide cylinder 40 and a second guide cylinder 50 arranged along the axial direction P, both of which are located in the second cavity 12; one end of the first guide cylinder 40 is connected to the diversion baffle 21, and the other end extends toward the outlet 14, and is provided with a first opening 41 facing the outlet 14; one end of the second guide cylinder 50 is connected to the bottom wall 16 of the tank and communicates with the outlet 14, and the other end extends toward the diversion baffle 21, and is provided with a second opening 51 facing the diversion baffle 21; the second guide cylinder 50 is inserted into the first opening 41, and the gap between the outer wall of the second guide cylinder 50 and the inner wall of the first guide cylinder 40 forms a flow channel 60 connecting the first opening 41 and the second opening 51. In this way, the fluid entering the second chamber 12 needs to first reach the first opening 41 near the outlet 14 along the outer wall of the first pipe, then change direction and enter the first opening 41, then reach the second opening 51 near the diversion baffle 21 along the flow channel 60, then change direction and enter the second opening 51, then flow along the inner wall of the second cylinder to the outlet 14 (the flow direction of the fluid is shown by the double arrows in Figure 4), thereby increasing the time for the fluid to stay in the second chamber 12 for sterilization and further improving the sterilization efficiency.

[0085] Preferably, the length b2 of the flow channel 60 along the axial direction P is 50%-80% of the length b1 of the first guide cylinder 40. By setting the range of the length b2 of the flow channel 60 along the axial direction P, on the one hand, the length b2 of the flow channel 60 is avoided from being too short, resulting in a short fluid path and insufficient sterilization effect; on the other hand, the length b2 of the flow channel 60 is avoided from being too long, resulting in insufficient space between the end of the first guide cylinder 40 near the diversion baffle 21 and the second opening 51, which would affect the smooth flow of fluid from the first guide cylinder 40 into the second opening 51 of the second guide cylinder 50.

[0086] Specifically, the flow divider 21 includes a first part 212 and a second part 213 connected along the axial direction P. The first part 212 and the second part 213 enclose a receiving cavity 214 that is isolated from the cavity body. The heating device 30 has a disc-shaped structure and is located within the receiving cavity 214, with its outer periphery fitting against the inner wall of the receiving cavity 214. Thus, by setting the specific structure of the flow divider 21, a receiving cavity 214 isolated from the cavity body can be provided for the heating device 30. Furthermore, by setting the heating device 30 to a disc-shaped structure, with the heating device 30 located within the receiving cavity 214 and its outer periphery fitting against the inner wall of the receiving cavity 214, the heating device 30 can achieve a better heating effect on the fluid in the cavity. The flow divider cylinder 22 is connected to the first part 212, and the first guide cylinder 40 is connected to the second part 213.

[0087] Preferably, the diversion cylinder 22 and the first part 212 are integrally formed, and the first guide cylinder 40 and the second part 213 are integrally formed.

[0088] The tank body 10 includes a first tank body 17 and a second tank body 18 that are detachably connected along the axial direction P. An inlet 13 is located in the first tank body 17, and an outlet 14 is located in the second tank body 18. The first tank body 17 and the second tank body 18 enclose a cavity. The first tank body 17 and a flow divider 21 enclose a first cavity 11, and the second tank body 18 and the flow divider 21 enclose a second cavity 12. The length of the first tank body 17 along the axial direction P is less than the length of the second tank body 18 along the axial direction P. The flow divider 21 is fixed to the inner wall of the first cavity 11.

[0089] In this embodiment, the mixing tank 1 also includes a temperature sensor 70, which is disposed on the tank body 10 and is used to detect the temperature of the fluid in the cavity.

[0090] This embodiment also provides a water heater, which includes the mixing tank 1 as described above.

[0091] In this embodiment, the mixing tank 1 and the water heater containing it are equipped with a heating device 30 to heat the fluid located in the cavity, thereby achieving the beneficial technical effect of high-temperature sterilization. Furthermore, by setting the heating device 30 in the diversion baffle 21 that separates the first cavity 11 and the second cavity 12, the fluids in the first cavity 11 and the second cavity 12 located on both sides of the diversion baffle 21 can be heated simultaneously at the middle position of the cavity, thereby maximizing the heating efficiency of the heating device 30.
