[0002] Common soda ice water containers typically have a baffle between the room temperature water inlet area and the ice water area to reduce the disturbance caused by room temperature water entering the container. However, the baffle can only serve to block the water flow and cannot suppress the turbulence generated when room temperature water enters the container. The ice water is easily disturbed by the turbulence, thus reducing the utilization rate of the ice water. Utility Model Content

The water outlet of the flow guide channel forms a water outlet. The flow guide channel is provided with a flow guide surface for guiding water flow. The flow guide surface causes the water flowing through the flow guide surface to change from turbulent flow to laminar flow.

[0006] Furthermore, it also includes a bottom wall, with the first end of the bottom wall being higher than its second end. The bottom wall has side walls on both sides that connect from the first end to the second end. The space enclosed by the bottom wall and the two side walls forms a flow channel. The bottom wall has a flow-guiding surface at least in part. The bottom wall and the two side walls are connected to the disc body. The gap between the second end of the bottom wall and the disc body forms a water outlet.

[0007] Furthermore, the inner surface of the bottom wall smoothly transitions from the water inlet to the water outlet, forming a guide surface, and the absolute value of the slope of the guide surface gradually decreases from the water inlet to the water outlet.

[0008] Furthermore, the water outlet has a horizontal or nearly horizontal direction.

[0009] Furthermore, each water inlet and outlet is evenly arranged circumferentially along the axis of the disc.

[0010] Furthermore, the water outlets all point in the same clockwise direction, causing the water to flow out in a spiral shape after passing through each guide channel.

[0011] An ice water tank includes an outer tank body and a cover body connected to the outer tank body. An evaporator is provided inside the outer tank body. A first water outlet is provided at the bottom of the outer tank body. A first water inlet is provided on the cover body. A guide plate as described above is provided on the upper part of the outer tank body. The space between the cover body and the guide plate forms a buffer zone. The first water inlet and the water inlet are connected to the buffer zone. The water outlet is connected to the lower space of the outer tank body.

[0012] Furthermore, the first water inlet and the water passage inlet are staggered.

[0013] Furthermore, the cover and the guide plate are respectively provided with a first clearance hole and a second clearance hole, and a part of the evaporator passes through the first clearance hole and the second clearance hole.

[0014] Furthermore, an inner tank is also provided inside the outer tank. The space between the outer tank and the inner tank constitutes a water storage space. A guide plate is fitted outside the inner tank. Each water outlet is connected to the water storage space. A portion of the outer side of the inner tank overlaps with the guide plate. The guide plate is connected to the cover, thereby pressing the inner tank tightly against the cover. The cover has a second water inlet and a second water outlet connected to the inner tank. The evaporator is located in the water storage space.

[0015] Furthermore, the opening of the inner tank is provided with an overlapping portion extending radially outward, which overlaps with the guide plate.

[0016] Furthermore, the cover is provided with a first liquid level hole for monitoring the water level of the outer tank and a second liquid level hole for monitoring the water level of the inner tank.

[0017] The beneficial effects of this utility model are:

The present invention proposes a flow guide plate, comprising a plate body, the plate body having a plurality of water inlets, each water inlet being connected to a flow guide channel, the water outlet of the flow guide channel constituting a water outlet. In use, room temperature water is divided into several water flows through each water inlet and the flow guide channel, avoiding the concentration of room temperature water in a localized area impacting the ice water and reducing the disturbance to the ice water when room temperature water enters. In addition, the flow guide channel is provided with a flow guide surface for guiding the water flow, causing the water flowing through the flow guide surface to change from turbulent flow to laminar flow, reducing the turbulence and flow velocity generated when room temperature water enters, further reducing the disturbance to the ice water, thereby improving the utilization rate of the ice water.

[0019] 2. The present invention proposes a flow guide plate, wherein the inner surface of the bottom wall smoothly transitions from the water inlet to the water outlet, the inner surface of the bottom wall forms a flow guide surface, and the absolute value of the slope of the flow guide surface gradually decreases from the water inlet to the water outlet, making the flow guide surface concave in shape.

Detailed Implementation

[0034] The following is combined with Figures 1-8 This utility model will be described in detail.

[0035] This embodiment proposes a flow guide plate 10, including a plate body 20. The plate body 20 has several water inlets 201, each connected to a flow guide channel 30. The outlet end of the flow guide channel 30 forms a water outlet 40. In use, room temperature water is divided into several water flows through the various water inlets 201 and the flow guide channel 30, avoiding the concentration of room temperature water in a localized area that impacts the chilled water and reducing the disturbance caused to the chilled water when room temperature water enters. At the same time, the flow guide channel 30 is provided with a flow guide surface 50 for guiding the water flow, causing the water flowing through the flow guide surface 50 to change from turbulent flow to laminar flow, reducing the turbulence and flow velocity generated when room temperature water enters, further reducing the disturbance to the chilled water, and improving the utilization rate of the chilled water.

[0036] The guide plate 10 also includes a bottom wall 301. The first end 3011 of the bottom wall 301 is higher than its second end 3012. The bottom wall 301 has side walls 302 on both sides, which are connected from the first end 3011 to the second end 3012. The side walls 302 and the bottom wall 301 are smoothly connected. The space enclosed by the bottom wall 301 and the two side walls 302 forms a guide channel 30. The bottom wall 301 has a guide surface 50 at least in part. The bottom wall 301 and the two side walls 302 are connected to the plate body 20. The gap between the second end 3012 of the bottom wall 301 and the plate body 20 forms a water outlet 40.

[0037] like Figure 1 and Figure 2As shown, the inner surface of the bottom wall 301 smoothly transitions from the water inlet 201 to the water outlet 40, thus forming a guide surface 50. The absolute value of the slope of the guide surface 50 gradually decreases from the water inlet 201 to the water outlet 40, making the guide surface 50 concave overall. The water outlet 40 is horizontal or tends to be horizontal, thus avoiding direct impact of room temperature water with ice water when it enters.

[0038] like Figure 1 As shown, the water inlets 201 and outlets 40 are evenly arranged circumferentially along the axis of the disc 20. The evenly arranged water inlets 201 divide the ambient temperature water into several streams, and the evenly arranged outlets 40 ensure that each stream flows evenly to all parts of the ice water surface. Furthermore, the outlets 40 all point in the same clockwise direction, causing the water to flow out in a spiral shape after passing through the guide channels 30, preventing the water from colliding with each other and generating turbulence. The flow direction is as follows: Figure 7 As shown.

[0039] like Figures 4-6 As shown, this embodiment also proposes an ice water tank 60, including an outer tank body 70 and a cover 90 connected to the outer tank body 70. An evaporator 100 is provided inside the outer tank body 70. A first water outlet 1102 is provided at the bottom of the outer tank body 70, and a first water inlet 1101 is provided on the cover 90. A guide plate 10, as described above, is provided at the upper part of the outer tank body 70. The space between the cover 90 and the guide plate 10 forms a buffer zone 130. The first water inlet 1101 and the water inlet 201 are connected to the buffer zone 130, and the water outlet 40 is connected to the lower space of the outer tank body 70. The buffer zone 130 is used to block the inflow of room temperature water, thereby reducing the inflow velocity of the room temperature water and creating the basic conditions for the transition from turbulent flow to laminar flow.

[0040] like Figure 6 As shown, the first water inlet 1101 and the water inlet 201 are staggered to prevent room temperature water from flowing directly to the water inlet 201 and to slow down the flow rate of room temperature water.

[0041] like Figure 8 As shown, the cover 90 and the guide plate 10 are respectively provided with a first clearance hole 1501 and a second clearance hole 1502. The second clearance hole 1502 is provided on the bottom wall 301, and a part of the evaporator 100 passes through the first clearance hole 1501 and the second clearance hole 1502.

[0042] like Figure 4 As shown, an inner tank 80 is also provided inside the outer tank 70. The space between the outer tank 70 and the inner tank 80 forms a water storage space 140. A guide plate 10 is fitted outside the inner tank 80. Each water outlet 40 is connected to the water storage space 140, and a portion of the outer side of the inner tank 80 overlaps with the guide plate 10. Figure 5 The inner tank 80 has an overlapping portion 801 extending radially outward at its opening, which overlaps with the guide plate 10. The guide plate 10 is connected to the cover 90, thereby pressing the inner tank 80 against the cover 90. Specifically, the outer tank 70 has a plurality of first connecting holes 1601, and the cover 90 has a plurality of first connecting members 1701, which are threadedly connected to the first connecting holes 1601, so that the outer tank 70 is connected to the cover 90; the plate 20 has a second connecting hole 1602, and the cover 90 has a plurality of second connecting members 1702, which are threadedly connected to the second connecting holes 1602, so that the guide plate 10 is connected to the cover 90.

[0043] like Figure 3 As shown, the cover 90 is also provided with a second water inlet 1201 and a second water outlet 1202 connected to the inner tank 80. Figure 4 An evaporator 100 is shown disposed in a water storage space 140. The cover 90 also has a first level hole 1801 for monitoring the water level in the outer tank 70 and a second level hole 1802 for monitoring the water level in the inner tank 80. The first level hole 1801 and the second level hole 1802 are used to place probes to monitor the current water level. The cover 90 also has a mounting hole 190, within which is an vent valve connected to the water storage space 140 to release excess pressure within the water storage space 140.

[0044] This embodiment proposes an ice water tank 60, with a water storage space 140 for holding drinking water and an inner tank 80 for holding soda water. An evaporator 100 refrigerates both the drinking water and soda water. Water is supplied to the water storage space 140 through a first inlet 1101 and a first outlet 1102, and to the inner tank 80 through a second inlet 1201 and a second outlet 1202.

[0045] During use, the water level in the storage space 140 drops, requiring replenishment through the first inlet 1101. Specifically, ambient temperature drinking water flows into the buffer zone 130 through the first inlet 1101. Due to the staggered arrangement between the first inlet 1101 and the water inlet 201, the flow rate of the ambient temperature drinking water is slowed down. Then, the ambient temperature drinking water flows into the guide channel 30 through the water inlet 201, and the guide surface 50 causes the flowing water to change from turbulent to laminar flow. Finally, the ambient temperature drinking water flows into the storage space 140 in a spiral shape through the water outlet 40. This uniformly squeezes the ice water in the storage space 140 out of the first outlet 1102, increasing the utilization rate of the ice water to over 80%.

[0046] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
