[0053] In order to make the person skilled in the art better understand the utility model scheme, the technical scheme in the utility model embodiment will be described clearly and completely below in conjunction with the drawings.
[0054] Reference Figures 1 to 16The first embodiment of the present application provides a purified drinking machine, which comprises a storage ice box 10, an ice maker 20, an ice making box 30 and a drainage box 40; the ice maker 20 and the ice making box 30 are arranged at the opening of the storage ice box 10, and the ice making box 30 can be pivoted relative to the ice maker 20 to switch between an ice making state and an ice removing state; the opening of the storage ice box 10 is further provided with the drainage box 40 which can be pivoted relative to the ice maker 20 around the ice making box 30, and the inner cavity of the drainage box 40 is at least partially always covered on the outer wall of the ice making box 30; wherein the drainage box 40 is provided with a drainage opening 41 which is not communicated with the opening of the storage ice box 10.
[0055] When the ice making box 30 is switched from the ice making state to the ice removing state, the opening of the drainage box 40 is upward to receive the liquid poured out of the ice making box 30, and then the liquid flows out of the drainage box 40 from the drainage opening 41 based on the gravity effect.
[0056] When the ice making box 30 is switched to the ice removing state, the opening of the drainage box 40 is downward or toward one side to avoid blocking the ice blocks in the ice making box 30 from falling into the storage ice box 10.
[0057] In the embodiment, the ice maker 20 is used to make ice in the ice making box 30. Through the pivoting action of the ice making box 30, the ice making box 30 can be switched from the ice making state to the ice removing state, and combined with the pivoting action of the drainage box 40, the drainage box 40 is pivoted in cooperation with the state of the ice making box 30.
[0058] Referring to Figures 9 to 16 When the ice making box 30 is poured out of the liquid, the drainage box 40 is in a static state relative to the storage ice box 10, the ice making box 30 is pivoted relative to the drainage box 40 and around the ice maker 20, and at this time the opening of the drainage box 40 is upward; or, first the drainage box 40 is in a static state, then the ice making box 30 is pivoted relative to the drainage box 40 and around the ice maker 20, and then the drainage box 40 is pivoted around the ice maker 20 synchronously with the ice making box 30, at this time the opening edge of the drainage box 40 is still higher than the opening edge of the ice making box 30, and the opening of the drainage box 40 is not communicated with the inner cavity of the storage ice box 10; and then the liquid in the ice making box 30 flows out of the drainage box 40 from the drainage opening 41 based on the gravity effect.
[0059] Referring to Figures 9 to 16When the ice making box 30 is switched to the ice discharging state, the ice making box 30 is pivoted around the ice maker 20, the opening of the ice making box 30 faces downward or to one side, and the projection of the opening of the ice making box 30 on the horizontal plane is directly opposite the opening of the ice storage box 10 and located in the opening of the ice storage box 10. At the same time, the drainage box 40 is also pivoted around the ice maker 20, the opening of the drainage box 40 faces downward or is oriented to the same side as the opening of the ice making box 30, so that the ice in the ice making box 30 falls into the ice storage box 10 under the action of gravity, and the opening of the drainage box 40 faces downward or is oriented to the same side as the opening of the ice making box 30, so that the drainage box 40 does not block the ice in the ice making box 30 from falling into the ice storage box 10.
[0060] Therefore, the net drinking machine can not only discharge the residual ice water in the ice making box 30, but also avoid the drainage box 40 from blocking the ice in the ice making box 30 from being discharged into the ice storage box 10. That is, the net drinking machine can avoid the output error of the ice and the residual water after ice making. Moreover, the inner cavity of the drainage box 40 is at least partially always covered on the outer wall of the ice making box 30, the ice making box 30 and the drainage box 40 are pivoted, and the ice making box 30 and the drainage box 40 are arranged at the opening of the ice storage box 10, so that the drainage box 40 and the ice making box 30 do not interfere with and collide with the ice storage box 10, thereby avoiding the increase of the occupied space of the ice making device.
[0061] Specifically, the opening of the drainage box 40 is oriented to the same side as the opening of the ice making box 30, and the plane in which the opening of the drainage box 40 is located is parallel or intersects with the plane in which the opening of the ice making box 30 is located.
[0062] With reference to Figures 1 to 7 , the inner and outer wall surfaces of the ice making box 30 and the drainage box 40 extending along the pivoting axis direction thereof are in the shape of a circular arc. That is, the inner wall surface of the ice making box 30 and the drainage box 40 extending along the pivoting axis direction thereof and the outer wall surface of the ice making box 30 and the drainage box 40 extending along the pivoting axis direction thereof are in the shape of a circular arc.
[0063] In the present embodiment, compared with the prior art, the space occupied by the drainage box 40 is only slightly larger than that of the ice making box 30, thereby saving the space occupied by the structure of the ice making part.
[0064] With reference to Figures 1 to 8 , the drainage box 40 is enclosed by a bottom wall 42 extending along the pivoting axis direction of the drainage box 40, and a first end wall 43 and a second end wall 44 connected to the two ends of the bottom wall 42, respectively;
[0065] The drainage port 41 is arranged on the first end wall 43, and the drainage port 41 is arranged close to the bottom wall 42 and extends from the opening of the drainage box 40 to the bottom of the inner cavity of the drainage box 40;
[0066] In the present embodiment, the drainage box 40 and the drainage port 41 are arranged so that the drainage is smooth during the pivoting of the drainage box 40.
[0067] In some embodiments, the drainage box 40 is enclosed by a bottom wall 42 extending along the pivoting axis of the drainage box 40, and a first end wall 43 and a second end wall 44 connected to the two ends of the bottom wall 42 respectively;
[0068] The drainage port 41 is arranged on the bottom wall 42, and the drainage port 41 is close to the first end wall 43 and extends from the opening of the drainage box 40 to the bottom of the inner cavity of the drainage box 40.
[0069] Specifically, the ice-making box 30 and the drainage box 40 are arranged in a nested manner, the second end wall 44 of the drainage box 40 is connected to the pivoting controller 70, and the end wall of the ice-making box 30 close to the second end wall 44 is connected to the pivoting controller 70.
[0070] Referring to Figure 1 , Figure 2 , Figure 5 and Figure 7 , one side edge of the bottom wall 42 is provided with a water baffle 45, and the water baffle 45 and the inner wall of the drainage box 40 form a turnover water storage cavity 451.
[0071] Specifically, the water baffle 45 is close to the first extension end of the drainage port 41, and the first extension end of the drainage port 41 is close to the opening of the drainage box 40.
[0072] When the liquid in the ice-making box 30 is poured into the drainage box 40, the ice-making box 30 is pivoted relative to the drainage box 40, and the ice-making box 30 is pivoted in a direction away from the water baffle 45. When the ice-making box 30 is converted from the ice-making state to the ice-removing state, the pivoting direction of the ice-making box 30 and the drainage box 40 is the same as the pivoting direction of the ice-making box 30 in the above-mentioned drainage state.
[0073] In the present embodiment, the water baffle 45 of the present embodiment is used to avoid the ice-making box 30 from pivoting too fast, and the water flow is discharged out of the drainage box 40. Moreover, when the drainage box 40 is pivoted along with the ice-making box 30 around the ice maker 20, the turnover water storage cavity 451 is used to avoid the residual ice water in the drainage box 40 from being discharged out of the opening of the drainage box 40 into the ice storage box 10, and the ice-making box 30 can continue to pivot to ensure that the ice water in the ice-making box 30 is completely discharged into the drainage box 40. In summary, the water in the drainage box 40 is only discharged through the drainage port 41, thereby ensuring the correct output of the ice cubes and the residual ice water.
[0074] Referring to Figure 1The bottom wall 42 extends obliquely along the pivoting axis direction of the drain box 40, and one end connected with the first end wall 43 is farther away from the pivoting axis of the drain box 40 than the other end. That is, the bottom wall 42 of the drain box 40 is arranged obliquely.
[0075] In the embodiment, the drain box 40 is arranged obliquely, so that liquid at the first end wall 43 flows quickly to the second end wall 44, and the draining speed of the drain box 40 is accelerated.
[0076] With reference to Figures 1 to 4 The pure drinking machine further comprises a cold water tank 50, which is communicated with the ice making box 30 at a water outlet end, and is used to provide liquid for ice making to the ice making box 30.
[0077] The cold water tank 50 is sleeved outside the ice storage box 10, and at least part of the inner cavity wall and the ice storage box 10 form a backwater cavity 51.
[0078] In the embodiment, the ice storage box 10 and the cold water tank 50 are sleeved, the occupied space of the overall structure of the pure drinking machine is reduced, the backwater cavity 51 is utilized, and the water in the drain box 40 is drained through the drain port 41 and the backwater cavity 51 and then into the cold water tank 50. Thus, the pure drinking machine is sleeved, the opening of the ice storage box 10 and the water inlet of the cold water tank 50 are separately arranged at two positions, the draining direction of the drain box 40 and the ice discharging direction of the ice making box 30 are separately arranged, and the output of ice blocks and residual ice water is ensured to be correct.
[0079] With reference to Figures 1 to 4 The inner cavity of the drain box 40 is enclosed by a bottom wall 42 extending along the pivoting axis direction of the drain box 40, and a first end wall 43 and a second end wall 44 connected to two ends of the bottom wall 42 respectively. The drain port 41 is arranged on the first end wall 43 or the bottom wall 42, and the projection of the drain port 41 on a horizontal plane is opposite to the backwater cavity 51.
[0080] In the embodiment, the drain port 41 is utilized, and it is ensured that the liquid drained by the drain port 41 is drained only into the backwater cavity 51 and then into the cold water tank 50.
[0081] With reference to Figures 1 to 4 The inner cavity of the drain box 40 is enclosed by a bottom wall 42 extending along the pivoting axis direction of the drain box 40, and a first end wall 43 and a second end wall 44 connected to two ends of the bottom wall 42 respectively. The drain port 41 is arranged on the first end wall 43, or arranged on the bottom wall 42 and close to the first end wall 43.
[0082] The ice storage box 10 comprises a rear wall 11, a side wall 12, and a leading-out wall 13, at least one of the side walls 12 is connected with the rear wall 11 through a slant wall 14, and the slant wall 14 and the inner cavity wall of the cold water tank 50 enclose the water return cavity 51;
[0083] The ice storage box 10 is further provided with a water guide 60 at the opening, the water guide 60 is open at the upper end and used for receiving the liquid flowing out of the drain port 41, the lower end of the water guide 60 is not communicated with the opening of the ice storage box 10 and is communicated with the opening of the water return cavity 51.

[0085] With reference to Figures 1 to 4 , the stroke of the ice making box 30 from the ice making state to the ice removing state comprises a first stroke and a second stroke;
[0086] In the first stroke, the ice making box 30 starts to pivot relative to the drain box 40 from the ice making state, and the opening of the ice making box 30 gradually inclines to one side, so that the liquid in the ice making box 30 flows into the drain box 40;
[0087] In the second stroke, the ice making box 30 and the drain box 40 pivot relative to the ice maker 20 synchronously, until the ice making box 30 is switched to the ice removing state, and the opening of the drain box 40 faces downward or to one side.
[0088] In the embodiment, in the first stroke, the liquid in the ice making box 30 flows into the drain box 40, and then is drained out of the drain port 41 into the water return cavity 51, and finally flows into the cold water tank 50.

[0091] In the embodiment, the limiting distance and the pivoting path of the ice making box 30 relative to the drainage box 40 are limited by the limiting guide sliding groove 46 and the limiting column 31, so that when the ice making box 30 discharges liquid to the drainage box 40, the ice making box 30 and the drainage box 40 are pivoted asynchronously, or only the ice making box 30 is pivoted and the drainage box 40 is in a static state; when the ice making box 30 is in a defrosting state, the ice making box 30 drives the drainage box 40 to pivot together through the limiting guide sliding groove 46 and the limiting column 31, thereby facilitating the control instruction of the pivoting controller 70.
[0092] Further based on the embodiment, the control end of the pivoting controller 70 penetrates the second end wall 44 of the drainage box 40 and is then fixed to one end wall of the ice making box 30, thereby saving the structural material of the pure water machine.
