[0037] Now, refer to Figures 1 to 3 Exemplary embodiments according to the present invention are described in more detail.

[0038] refer to Figure 1 and Figure 2 The present invention provides a beverage machine 100, which includes a water bath 110, a refrigeration system 120, a stirring device 130, and a flow disturbance device 140. The water bath 110 has a receiving chamber 111 for receiving a water bath liquid. The refrigeration system 120 includes a mounting frame 121 and an evaporator 123. The mounting frame 121 is disposed on the water bath 110 and is located above the receiving chamber 111. The evaporator 123 is disposed on the lower surface of the mounting frame 121 and is located in the receiving chamber 111. The evaporator 123 is used to cool the water bath liquid. The stirring device 130 extends into the receiving chamber 111 to stir the water bath liquid. The spoiler 140 is provided on the lower surface of the mounting frame 121 and is located in the water bath 110. The spoiler 140 includes a spoiler 143, which extends along the depth direction of the accommodating chamber 111. The spoiler 143 is provided with a plurality of spoiler holes 144. The spoiler holes 144 are used to allow the water bath liquid to flow through, and the position of the spoiler 143 along the depth direction corresponds to the liquid level L of the water bath liquid. The above-mentioned water bath liquid can be water or other liquid capable of heat exchange.

[0039] According to the beverage machine of the present invention, the turbulence is weakened or even eliminated by using the flow disturbance device, which can improve the noise situation, reduce the formation of large bubbles in the water, reduce the possibility of cavitation in the agitator, and balance the water flow speed to ensure the stability of the ice-water mixture.

[0040] Specifically, the beverage dispenser 100 of the present invention includes a water bath 110 for holding an ice-water mixture. The ice-water mixture is continuously kept stable in the water bath 110 via a refrigeration system 120 and a stirring device 130. Other sensors and a water replenishment device maintain the liquid level L. Consequently, drinking water can be cooled in the water bath 110 via the drinking water piping or by exchanging heat with the ice-water piping at another location, resulting in lower-temperature drinking water.

[0041] Among them, the refrigeration system 120 includes a mounting rack 121, which is preferably arranged at the top opening of the water bath tank 110. The refrigeration system 120 further includes an evaporator 123, a condenser 122, and a compressor 124. The evaporator 123 is arranged on the lower surface of the mounting rack 121 and is located in the accommodation cavity 111. The evaporator 123 is used to exchange heat with water to cool the water so as to generate ice. After the ice falls off the coil of the evaporator 123, it is mixed with water to form an ice-water mixture.

[0042] The condenser 122 and the compressor 124 are arranged on the upper surface of the mounting rack 121. Specifically, the condenser 122, the compressor 124, and the evaporator 123 are interconnected through a refrigerant pipeline. The compressor 124 compresses the refrigerant to form a high-temperature gaseous refrigerant. The high-temperature gaseous refrigerant is condensed into a liquid in the condenser 122 through a fan or other heat exchange device. The liquid refrigerant evaporates into a gas in the evaporator 123 and absorbs the heat of the accommodation cavity 111 to cool the water.

[0043] Among them, the condenser 122 is arranged on one side of the mounting rack 121, and the compressor 124 is arranged adjacent to the condenser 122. In other words, the compressor 124 is arranged on the other adjacent side of the mounting rack 121 relative to the condenser 122, rather than the opposite side. Preferably, in Figure 1 the illustrated embodiment, an opening is provided in the middle of the mounting rack 121, and the above-mentioned stirring device 130 is arranged at the opening. Exemplarily, the motor of the stirring device 130 is arranged at the opening and is entirely or partially located above the mounting rack 121. The stirring shaft 131 of the stirring device 130 penetrates through the opening, and one end of the stirring shaft 131 is connected to the output shaft of the motor, and the other end is connected to the stirring paddle 132. The main control device for controlling the refrigeration system 120 is arranged in the middle of the mounting rack 121, or rather, the main control device is arranged near the opening of the mounting rack 121, and the main control device and the compressor 124 are separated by the opening.

[0044] The flow disturbing device 140 further includes a first support portion 141, a second support portion 142, and the above-mentioned flow disturbing plate 143. Among them, the first support portion 141 is connected to the lower surface of the mounting rack 121. A fixing structure 145 is provided at the top end of the first support portion 141. The fixing structure 145 is used for fixedly connecting with the mounting rack 121. The fixing structure 145 includes a fixing hole 146. Exemplarily, the flow disturbing device 140 can be fixed on the mounting rack 121 by screws. The first support portion 141 extends in the depth direction to provide sufficient depth such that the flow disturbing plate 143 can correspond to the liquid level L.

[0045] The second support part 142 is connected to the lower side of the first support part 141, and the spoiler 143 is connected to the lower side of the second support part 142. In other words, the second support part 142 is connected between the first support part 141 and the spoiler 143. Preferably, the second support part 142 extends in a plane perpendicular to the depth direction, thereby providing sufficient space for arranging the spoiler 143. For example, the number of spoilers 143 is set to at least two, that is, two or more spoilers 143 are provided, and the plurality of spoilers 143 can be arranged on the lower surface of the second support part 142 and spaced from each other by a sufficient space.

[0046] Moreover, as a preferred embodiment, the second support part 142 is provided with a through hole 147, the stirring shaft 131 of the stirring device 130 passes through the through hole 147, and the spoiler 143 is arranged adjacent to the through hole 147. Exemplarily, the spoiler 143 can be continuously arranged around the through hole 147.

[0047] In this embodiment, the number of spoilers 143 can also be set to at least two, and at least two spoilers 143 are symmetric with respect to the central axis of the through hole 147. For example, the two spoilers 143 shown in the figure are arranged facing each other. In an embodiment not shown, three, four, five or the like spoilers 143 can also be provided, and the plurality of spoilers 143 are symmetrically arranged around the central axis of the through hole 147.

[0048] This setting method can make the liquid surface L turbulence caused by the stirring paddle 132 of the stirring device 130 contact the spoiler 143 as early and fully as possible, thereby weakening the turbulence, and helping to reduce the decline amplitude of the central liquid surface L of the stirring vortex, thereby reducing the occurrence of cavitation.

[0049] When the number of spoilers 143 is set to two, the number of the first support parts 141 is also preferably set to two, the two first support parts 141 are arranged opposite to each other, and the first support part 141 and the spoiler 143 are offset in the depth direction.

[0050] As an alternative embodiment, the shapes of the plurality of spoiler holes 144 include at least one of a rectangle, a circle, a triangle, an ellipse, a square, a racetrack shape, and an arc shape. In other words, the forms of the plurality of spoiler holes 144 can be the same, and a rectangle, a circle, a triangle, an ellipse, a square, a racetrack shape, and an arc shape can be selected. Or, the plurality of spoiler holes 144 can select different shapes, such as a mixture of the above-mentioned plurality of shapes.

[0051] As a preferred embodiment, as Figures 1 to 3 shown, the spoiler hole 144 is configured as a rectangle, and the length direction of the spoiler hole 144 is parallel to the depth direction, or in other words, the spoiler hole 144 extends vertically.

According to the teachings of the present utility model, more variations and modifications can be made, and these variations and modifications all fall within the scope of protection required by the present utility model.
