The invention proposes a soda machine.

In the embodiment of the present invention, as shown in FIG. 1 to FIG. 4, the soda machine includes:

Housing 70;

a water tank 10 disposed in the outer casing 70;

An evaporator 40 is located in the water tank 10 and disposed near the top of the water tank 10;

a spray pipe, the lower end is in communication with the water tank 10, and the upper end is disposed corresponding to the evaporator 40;

a spray water pump 20 (shown in FIG. 8) is disposed on the spray pipe for spraying water in the water tank 10 to the evaporator 40;

The soda water tank 50 is disposed in the outer casing 70, and the soda water tank 50 is provided with a water inlet 51, a water outlet 52, and an air inlet 53, and the water inlet 51 communicates with the water tank 10.

In this embodiment, the outer casing 70 is substantially in the shape of a rectangular parallelepiped. Of course, in other embodiments, the outer casing 70 may also have a shape such as a square, a cylinder or an elliptical cylinder.

In the present embodiment, the water tank 10 is in communication with the external clean water source, and the water flowing into the water tank 10 is clean water to flow into the soda water tank 50 after cooling to prepare the soda water. Usually, a filter element can be disposed in the soda machine, and the tap water is filtered through the filter core and flows into the water tank 10. A water level sensor may be disposed in the water tank 10 for detecting the water level in the water tank 10, thereby preventing the water tank 10 from entering the water in time or excessive water inflow. Since the water tank 10 is for preparing cold water, a water temperature sensor can be disposed in the water tank 10 in order to obtain parameters of the cold water. In order to avoid loss of cooling in the water tank 10, the outer surface of the water tank 10 is usually wrapped with an insulating material such as heat insulating cotton. The water tank 10 includes a box body and a box cover that seals and closes the box body, so that dust or the like can be prevented from entering the water tank 10, and the water in the water tank 10 is prevented from being polluted by the outside. In order to facilitate the cleaning of the water tank 10, the water in the water tank 10 is replaced, and a drain port may be arranged at the bottom of the water tank 10, and a drain pipe is externally connected to the outside.

The evaporator 40 is disposed within the water tank 10, preferably near the top of the water tank 10, so that the water tank 10 can accommodate more water while avoiding contact with water within the water tank 10. The upper end of the spray pipe is disposed corresponding to the evaporator 40, meaning that the upper end of the spray pipe is located directly above the evaporator 40 to spray water from the top; or the upper end of the spray pipe is located on the side of the evaporator 40. The spray pipe sprays water from the side to the evaporator 40. When the spray water pump 20 pumps the water at the bottom of the water tank 10 to the upper end of the spray pipe, since the water pressure in the spray pipe is large, it can be sprayed onto the evaporator 40 in a spray form, and then exchanged heat with the evaporator 40. It flows down and converges to the bottom of the water tank 10, and is again drawn into the spray pipe by the spray water pump 20, so that the water in the water tank 10 is turned into cold water.

In this embodiment, the upper end of the shower pipe is provided with a shower so that the water sprayed from the spray pipe is sprinkled on the evaporator 40, especially in the case where the heat exchange area of the evaporator 40 is large. For example, a fin-and-tube heat exchanger is capable of better contact with water. Of course, there is no need to set a shower on the upper end of the spray pipe.

In order to make the whole structure more compact, the soda water tank 50 can be disposed in the water tank 10 to form an integral module for easy installation and disassembly. Of course, the soda can 50 can also be disposed separately from the water tank 10. The air inlet 53 of the soda can 50 is connected to the air supply means, such as a carbon dioxide gas cylinder disposed in the outer casing 70, or a carbon dioxide gas cylinder independently of the soda machine. Then, when the soda water device is operated, the cold water in the water tank 10 flows into the soda water tank 50 through the water inlet 51, and the carbon dioxide gas in the carbon dioxide gas cylinder is charged into the soda water tank 50 from the air inlet 53, and the cold water and the carbon dioxide gas are The soda water is repeatedly mixed in the soda water tank 50, and the soda water flows out from the water outlet 52 of the soda water tank 50 for the user to drink.

In the present invention, since the evaporator 40 is disposed near the top of the water tank 10, and a spray pipe and a spray water pump 20 are disposed in the outer casing, the water at the bottom of the water tank 10 continuously passes through the spray water pump 20, and is sprayed through the spray pipe. To the evaporator 40, heat is exchanged with the evaporator 40, and the heat-exchanged water flows downward from the high portion where the evaporator 40 is located to the bottom of the water tank 10, and is mixed with the water in the water tank 10. Since the water in the water tank 10 continuously circulates under the driving of the spray water pump 20, the water in the water tank 10 is more uniformly mixed, and the water temperature in each position is more uniform, so that the soda water thus obtained has a better mouthfeel.

In the embodiment, the soda water tank 50 is disposed in the water tank 10, and the cold air in the water tank 10 can surround the soda water tank 50, and the soda water tank 50 is cooled to make the soda in the soda water tank 50. Lower water temperature is more conducive to the dissolution of carbon dioxide gas.

In this embodiment, the water tank 10 includes a box body that is open upward, and a box cover that seals the open port, and the box body and the box cover can be sealed by a sealing ring or sealed by glue. An ear plate 551 is protruded from the top surface of the soda can 50 and laterally protruded from the opposite side edges. Both the ear plates 551 are fixed to the cover. Specifically, the two ear plates 551 may be connected to the cover by screws, or the two ear plates 551 may be engaged with the cover. By providing the two ear plates 551 on the soda water tank 50, it is not necessary to punch holes in the soda water tank 50, which is advantageous for ensuring the strength and sealing of the soda water tank 50. At the same time, the two ear plates 551 are connected to the cover to facilitate the installation operation.

In this embodiment, the two ear plates 551 and the soda water tank 50 are two separate components. Of course, the two ear plates 551 can also be formed by two bumps integrally formed by the soda can 50. Specifically, a sock 55 is sleeved on the soda can 50, and the clip 55 is vertically disposed, and is circumferentially wound along the vertical direction of the soda can 50. The clip 55 is formed with two ear plates 551. In order to facilitate the clamping of the clamp 55 to the soda water tank 50, in the embodiment, the clamp 55 includes an upper clamp and a lower clamp, and the two ends of the upper clamp are connected with the two ends of the lower clamp to form a closed loop. The ring is formed, and the two joints of the upper clamp and the lower clamp each form an ear plate 551. Referring to FIG. 5, in order to position the clamp 55, a positioning rib 56 is disposed on the circumferential surface of the soda can 50. The extending direction of the positioning rib 56 coincides with the winding direction of the clamp 55 to make the clamp The 55 is wound along the positioning ribs 56 to position the clips 55 such that the ears 551 can be aligned with the attachment locations on the cover, such as the threaded holes or slots on the cover. The number of the positioning ribs 56 may be one, and the clip 55 abuts against the positioning ribs 56. Of course, the number of the positioning ribs 56 may also be two. The two positioning ribs 56 are spaced apart, and the clip 55 is located between the two positioning ribs 56 and abuts the two positioning ribs 56 respectively.

The soda water tank 50 in this embodiment is fixed to the box cover. In other embodiments, the soda water tank 50 can also be fixed to the box body. For example, a support plate, a soda water tank can be disposed on the side wall of the box body. 50 is placed on the support plate and supported by the support plate.

Referring to FIG. 4 and FIG. 6 together, the soda water tank 50 is pre-positioned to better ensure that the water inlet, the water outlet and the air inlet of the soda water tank 50 are docked with the corresponding let-off ports on the water tank 10, A positioning notch 16 is disposed on the inner side of the opposite side walls of the box body, and the positioning notch 16 is disposed upwardly through the top surface of the box body; each of the ear plates 551 is correspondingly disposed on one of the positioning notches. Within 16. The soda water tank 50 in this embodiment is placed laterally, and the water inlet, the water outlet and the air inlet are disposed on the same side of the soda water tank 50, and a retaining port is correspondingly arranged on the box body. In the specific installation, the water inlet, the water outlet and the air inlet of the soda water tank 50 are respectively connected to the corresponding pipelines, and then the pipeline is obliquely aligned with the delivery port on the tank body, and the soda water tank 50 is pressed at the same time. Away away from the end of the positional opening, the two ear plates 551 of the soda can 50 are caught in the two positioning notches 16, and the soda water tank 50 is horizontally restrained at this time, thereby avoiding the horizontal movement of the soda can 50, and Both sides of the soda can 50 are supported to prevent the soda can 50 from falling downward. Then, the cover is placed on the box, and the cover is screwed to the ear plate 551 by screws to limit the ups and downs of the soda can 50, thereby completing the installation of the soda can 50.

The soda water tank 50 in the present invention is preferably located in the ice storage chamber 12 of the water tank 10. A clamp 55 may be disposed on the outer circumference of the soda water tank 50. The clamp 55 is fixed to the water tank 10, and of course, may be disposed in the water tank 10. The soda can 50 is supported in the form of a support. In order to detect the water level in the soda water tank 50, a water level sensor is also disposed in the soda water tank 50 to prevent the water level in the soda water tank 50 from being too low or too high.

Referring to FIG. 7, in order to further ensure that the water temperature of the soda water tank 50 is lower, the soda machine further includes a cold water pipe 54 disposed in the soda water tank 50, and both ends of the cold water pipe 54 are sealed. The soda water tank 50 is provided to communicate with the water tank 10. In the present embodiment, since the water in the cold water pipe 54 comes from the water tank 10, and the water in the water tank 10 continuously exchanges heat with the evaporator 40, the temperature of the water in the cold water pipe 54 is low, so that the water in the soda water tank 50 is passed. In the manner in which the cold water pipe 54 is disposed, the water in the cold water pipe 54 continuously circulates with the water in the water tank 10, and continuously exchanges heat with the water in the soda water tank 50, so that the water temperature in the soda water tank 50 is further lowered, and Conducive to the full dissolution of carbon dioxide. A circulation water pump 57 is provided on the cold water pipe 54 to ensure that water in the cold water pipe 54 can flow and circulates with water in the water tank 10. In the present embodiment, the circulating water pump 57 is disposed inside the water tank 10. In addition, the cold water pipe 54 can communicate with the spray pipe, and the cold water pipe 54 and the spray pipe can share one water pump.

In this embodiment, both ends of the cold water pipe 54 are welded to the can body of the soda water tank 50 to prevent water leakage at the position where the cold water pipe 54 passes through the can body. Of course, the cold water pipe 54 and the can body can also be sealed by glue or a sealing ring. The cold water pipe 54 is preferably arranged in a tubular shape, so that the structure of the cold water pipe 54 is more compact, and it is more advantageous to utilize the inner space of the soda water tank 50, while avoiding the soda water tank while ensuring a large heat exchange area. 50 over-occupation of internal space.

In order to make the water flowing into the soda water tank 50 from the water inlet 51 to be mixed with the carbon dioxide gas, in the present embodiment, the diameter of the water inlet 51 gradually decreases from the outside to the inside. That is, in this embodiment, the water inlet 51 may be a tapered hole, so that when water flows from the larger inlet end of the water inlet 51 to the smaller water outlet, the water pressure becomes larger, and the rapid spray Out of the soda water tank 50, the water is misty and dispersed in the soda water tank 50, and the misty water can be sufficiently mixed with the carbon dioxide gas, so that the carbon dioxide gas is better dissolved in the water, so that the water is produced. The soda taste is better. The soda machine of the present invention can be dissolved in water by mixing the carbon dioxide gas by atomizing water, so that even if the water pressure and the gas pressure are low, the carbon dioxide gas can be dissolved into the water well, so that water having a lower water pressure can be used. The carbon dioxide with lower air pressure is therefore beneficial to improve the safety performance of the soda machine.

In order to allow the water flowing into the soda water tank 50 from the water inlet 51 to be mixed with the carbon dioxide gas, in other embodiments, the inner diameter of the water inlet pipe provided at the water inlet 51 may be set to It is larger than the diameter of the water inlet 51. In still other embodiments, by setting the aperture of the water inlet 51 on the soda machine to be small, the aperture of the inlet pipe is set larger, as water flows from the larger inlet pipe to the smaller inlet 51. The water pressure becomes large, and the water is quickly ejected from the water outlet end of the water inlet 51 to exhibit a mist.

Further, in the other embodiments, the outer surface of the can body is provided with a positioning sinking groove for sealing and inserting the inlet pipe, and the water inlet 51 is disposed at the bottom of the groove of the positioning sinking groove. Specifically, the inlet pipe may be welded, screwed, or tightly fitted to the wall of the positioning slot, and a sealing ring may be disposed between the outer wall of the inlet pipe and the wall of the positioning slot. Since the inlet pipe is inserted into the positioning sink, it is advantageous to position the installation position of the inlet pipe. Meanwhile, when the water inlets 51 are plural, a plurality of the water inlets 51 are disposed on the wall of the positioning sinking groove, so that the setting of the water inlet 51 is facilitated, and the plurality of inlets are The position of the nozzle 51 is defined as long as it is located in the positioning sink, thereby avoiding the positional displacement of the water inlet 51 and not being able to communicate well with the inlet pipe.

In order to allow the water flowing into the soda water tank 50 from the water inlet 51 to be mixed with the carbon dioxide gas, in other embodiments, the water inlet pipe provided at the water inlet 51 may also be provided from the water inlet 51. And extending into the tank body, and the water inlet pipe is located at one end of the tank body at least with a water spray hole, and the water spray hole has a smaller diameter than the inner pipe diameter of the water inlet pipe. In other embodiments, the number of water spray holes may be one or more, and a large water flow flowing out from the water inlet pipe is divided into one or more small water streams, which are sprayed from the water spray holes, and the atomization effect is obtained. Better, and the spray range is wider, which is more conducive to thorough mixing with carbon dioxide gas.

Referring to FIG. 2 again, in the embodiment, a partition 11 is disposed in the water tank 10 to partition the cavity of the water tank 10 into an ice storage chamber 12 and a water storage chamber 13 which are vertically distributed. The partition plate 11 is provided with a communication port 111 communicating with the ice storage chamber 12 and the water storage chamber 13. The evaporator 40 is located in the ice storage chamber 12, and the lower end of the spray tube extends The water storage chamber 13 is provided with an ice outlet 121 on the cavity wall of the ice storage chamber 12, and a conveying device is disposed in the ice storage chamber 12, and the conveying device is used for the evaporator 40. The fallen ice is transported to the ice outlet 121. In this embodiment, when water is continuously sprayed on the evaporator 40, part of the water will form an ice layer on the evaporator 40 due to the lower temperature of the evaporator 40, and will fall when the ice layer is thicker and thicker to form an ice block. Come down. In order to make the ice cube fall more easily, an electric heating film may be disposed on the outer surface of the evaporation tube or the fin of the evaporator 40. When the ice cube is thick, the electric heating film may be turned on to heat the ice cube, so that The ice cubes fall off smoothly, and during other time periods, the electric heating film is de-energized to avoid excessive heating in the water tank 10. When the ice cubes fall onto the partition 11, the conveying device transports the ice cubes to the ice outlet 121 and falls out from the ice outlet 121 for the user to use. At the same time, cold water which does not form ice blocks flows down from the communication port 111 on the partition 11, accumulates in the water storage chamber 13, and is subjected to the next cycle or preparation of soda water. In the present embodiment, by providing the form of the partition plate 11, the ice block can be prevented from falling, and at the same time, by providing the communication port 111 on the partition plate 11, it is ensured that the cold water can smoothly flow down, and the ice water separation is truly achieved.

In this embodiment, the conveying device specifically includes a screw rod 30 and a driving member. The screw rod 30 is driven by the driving member to continuously transport the ice cube at one end of the screw rod 30 to the other end, and the ice outlet 121 is close to the screw rod. The other end of the 30 is set. In other embodiments, the conveying device may further include a movable baffle and a driving member that drives the movable baffle to move toward and away from the ice outlet 121, and the driving member drives the movable baffle to move back and forth, and the movable baffle will The ice cubes are dialed to the ice outlet 121. The ice outlet 121 can be provided with a downwardly and outwardly extending slope, so that when the ice reaches the edge of the ice outlet 121, it can slide out along the slope for the user to access. The drive member is specifically a device that powers a motor or a cylinder.

Further, a buffer table 14 is disposed in the ice storage chamber 12 and directly below the evaporator 40, and the top surface of the buffer table 14 is an inclined surface. By setting the buffer table 14, the ice block can be dropped on the buffer table 14 and then dropped onto the partition plate 11. The buffer table 14 acts as a buffer for the ice block, thereby preventing the potential energy of the ice block from being excessively large and detrimental. Separator 11. By setting the top surface of the buffer table 14 in an inclined shape, it is possible to ensure that the ice cube can smoothly slide down. Preferably, the top surface of the buffer table 14 is arranged in a zigzag or wave shape, and the contact area between the ice block and the buffer table 14 is small, the friction is smaller, and the sliding of the ice block is smoother. In this embodiment, the buffer table 14 is a wedge.

Further, the soda machine further includes a full ice detector, and the full ice detector includes:

a first magnetic member (not shown) disposed adjacent to an upper edge of the inclined surface and fixed to the water tank 10;

a second magnetic member 60 extending in the up-and-down direction and blocking the lower edge of the inclined surface, the top of the second magnetic member 60 being rotatably connected to the inner wall of the water tank 10; the second magnetic attraction The member 60 has a first state vertically disposed by the magnetic attraction of the first magnetic member, and is pressed away from the ice block dropped onto the buffer table 14 while being away from the first a second state in which the direction of rotation of the magnetic member is rotated;

In this embodiment, one of the first magnetic member and the second magnetic member 60 is a magnet, and the other corresponds to a magnet or a metal member, and the first magnetic member and the second magnetic member The member 60 is capable of generating suction that is attracted to each other.

The first magnetic member may be disposed in the water tank 10 or may be disposed outside the water tank 10. As long as the second magnetic member 60 is in the first state, the first magnetic member can generate magnetic attraction with the first magnetic member. Just fine. For example, in one embodiment, the first magnetic member is disposed outside of the water tank 10 and is a steel tube, and the second magnetic member 60 is a magnet.

In this embodiment, the second magnetic member 60 includes a turret 61 and a magnetic attraction portion 62. The turret 61 extends in the up and down direction and is rotatably connected to the inner wall of the water tank 10. The turret 61 is disposed. On the side of the buffer table 14 on which the ice cubes slide, the magnetic attraction portion 62 is fixed to the bottom of the turret 61. Of course, the second magnetic member 60 may entirely be a magnetic portion 62 having magnetic properties without providing the turret 61.
