Technical Field
[0004]
[0001] The present invention relates to the technical field of refrigeration equipment, and particularly to a frozen drink machine.
Background Art
[0002] A frozen drink machine is a machine that provides a semi-frozen fruit juice beverage at a low temperature, and is classified into household and commercial types. A conventional household frozen drink machine generally consists of a housing, a refrigeration device, a storage tank, a stirring system, etc. The storage tank is provided with an inlet and an outlet, and a stirring blade is provided inside the storage tank. When the refrigeration device operates, the evaporator cools the beverage and freezes it in the storage tank. At the same time, under the agitation of the stirring mechanism, it is not completely frozen but gradually changes into a sherbet state. Since the stirring shaft extends from the cylindrical outer shell of the evaporator and is connected to the stirring blade, the bearing assembly requires a sealing member to prevent liquid leakage. However, the stirring shaft seal ring currently provided in the frozen drink machine cannot be removed and cannot be replaced after deterioration.
Summary of the Invention
Problems to be Solved by the Invention
[0003] The problem to be solved by the present invention is to provide a frozen drink machine that has the advantages of easy cleaning of the raw material container and easy replacement of the sealing pad of the rotating shaft, and overcomes the disadvantages of the prior art. To solve the technical problems described above, the technical solution of the present invention is as follows: A frozen drink machine comprising a housing, a refrigeration device, a stirring device, a controller, and a raw material container detachably attached to the housing, wherein the refrigeration device comprises a compressor, an evaporator, a condenser, and a throttling device, and further comprises an evaporator mounting cylinder, the evaporator being in close contact with the inner wall of the evaporator mounting cylinder, and the raw material container being fitted to the outside of the evaporator mounting cylinder, the stirring device comprising a stirring motor, a rotating shaft, and stirring blades, the tip of the rotating shaft passing through the evaporator mounting cylinder and being driven and connected to the stirring blades, the stirring blades being fitted to the outer wall of the evaporator mounting cylinder, the evaporator mounting cylinder being provided with a bearing seat for supporting the rotating shaft, the bearing seat comprising a fixing disc, a shaft sealing member, and a base, the base being installed inside the evaporator mounting cylinder, and the fixing disc and shaft sealing member being detachably fixed to the base on the outside of the evaporator mounting cylinder. [Effects of the Invention]
[0005] The beneficial effects of this invention are as follows: When not in operation, the raw material container can be removed from the housing and the inside can be cleaned. Since the fixing disc and shaft seal member are mounted on the outside of the evaporator mounting cylinder, if the shaft seal member deteriorates or breaks, it can be disassembled and replaced after removing the raw material container, thereby preventing the phenomenon of liquid leakage due to sealing failure. The front end of the raw material container of this invention protrudes outward and has a protruding chamber, and the front end of the stirring blade is close to the front panel of the protruding chamber, and the sloping upper wall is used to recirculate the frozen drink to the rear of the raw material container, preventing the frozen drink from accumulating and solidifying into clumps at the front end of the raw material container, resulting in a finer frozen drink. The sealing effect is improved by the rotating shaft passing through the shaft sleeve portion of the shaft seal member. The rotational locking connection between the first mounting ring of the container mounting seat and the second mounting ring of the container mounting plate makes positioning, mounting, removal, and cleaning of the raw material container extremely convenient. A sealing structure is provided between the first and second mounting rings, and between the first mounting ring and the evaporator mounting cylinder, to ensure that the frozen drink does not leak. A condensation water recovery section is provided below the raw material container to collect the condensation water formed on the outer wall of the raw material container by condensation in the air caused by the low temperature frozen drink, and discharge the condensation water through a water guide hole. A splash guard prevents the frozen drink from splashing out of the notch. The spout handle switch has two components, simplifying the switch structure and offering advantages in production and cost reduction. [Brief explanation of the drawing]

[0007] Specific embodiments of the present invention will be further described below with reference to the drawings. Those skilled in the art will understand that any changes, modifications, substitutions, and alterations made to these embodiments, without departing from the principles of the present invention, will still be within the scope of protection of the present invention.
[0008] Referring to Figures 1 to 14, the frozen drink machine comprises a housing 10, a refrigeration unit, a stirring unit, a controller, and a raw material container 1, the raw material container being detachably attached to the housing. The refrigeration unit comprises a compressor, an evaporator 201, a condenser, and a throttling device, and the stirring unit comprises a stirring motor, a rotating shaft, and stirring blades 4. The housing is divided into upper and lower parts, with the compressor and condenser installed in the lower housing chamber 101 (not shown) of the housing, and the stirring motor and motor cooling fan installed in the upper housing chamber 102 of the housing. The raw material container 1 is placed above the lower housing chamber 101, and the rear of the raw material container is close to the upper housing chamber 102. Ventilation grilles are provided on both the upper and lower parts of the rear plate 103 of the housing, and these ventilation grilles and the vents 104 on both side plates of the housing cooperate to form a heat dissipation air passage system for the compressor, condenser, and stirring motor. The frozen drink machine further includes an evaporator mounting cylinder 2, the evaporator being in close contact with the inner wall of the evaporator mounting cylinder, and the raw material container being fitted onto the outside of the evaporator mounting cylinder. The tip of the rotating shaft passes through the evaporator mounting cylinder and is driven and connected to the stirring blades, which are fitted onto the outer wall of the evaporator mounting cylinder. A bearing seat 7 for supporting the rotating shaft is provided on the evaporator mounting cylinder, and the bearing seat comprises a fixed disc 71, a shaft sealing member 72, and a base 73, the base being installed inside the evaporator mounting cylinder, and the fixed disc and shaft sealing member being detachably fixed to the base on the outside of the evaporator mounting cylinder.
[0009] The lower part of the front wall of the raw material container 1 protrudes outward to form a protruding chamber 12, and a spout is provided on the front panel of the protruding chamber, with a spout valve switch 3 above the spout. The front end of the stirring blade 4 is close to the front panel of the protruding chamber, and the upper wall of the protruding chamber has an inclined surface 121. A first through hole 711 is provided on the fixed disc, a second through hole is provided on the shaft seal member, a mounting column is provided inside the base, and a third mounting hole 731 is provided inside the mounting column. Fasteners penetrate the first through hole, the second through hole, and the third mounting hole to fix and connect the fixed disc, the shaft seal member, and the base. The shaft seal member 72 comprises a plate body 721 and a shaft sleeve portion 722, the shaft sleeve portion passing through the central hole of the fixed disc. Both the fixed disc and the base are made of plastic material, and screws can be used as fasteners. An oil seal mounting chamber 734 is provided inside the base, and an oil seal 74 is placed inside it. One end of the rotating shaft of the agitator is driven by a motor, and the other end passes through the shaft hole of the oil seal, the shaft seal member, and the fixing disc, extending from the front of the evaporator mounting cylinder and connecting to the agitator blade, thereby driving the agitator to operate. When the agitator blade rotates, it scrapes the frozen drink from the surface of the evaporator mounting cylinder on one hand and pushes the frozen drink toward the outlet of the raw material container on the other. Because the inner wall of the cylindrical wall of the evaporator mounting cylinder 2 is in close contact with the evaporator, the temperature of the cylindrical wall decreases, and the slurry in the raw material container is cooled through the cylindrical wall. As shown in Figure 3, a sleeve pipe 25 is provided inside the evaporator mounting cylinder 2, and one end of the sleeve pipe 25 is fixed to the base 73. After the base 73 and the sleeve pipe 25 are installed, the inner cylinder of the evaporator mounting cylinder 2 is foamed to form a foamed layer 23. Since the sleeve pipe is a hollow tube, the rotating shaft can pass through the entire evaporator mounting cylinder 2 through the sleeve pipe 25.
[0010] A container mounting seat 5 is provided on the housing, and the container mounting seat comprises a base plate 54 and a first mounting ring formed through the base plate, with the evaporator mounting cylinder passing through the first mounting ring. A container mounting plate 15 is provided at one end of the raw material container, and the container mounting plate 15 and the raw material container body can be formed by ultrasonic welding, and a second mounting ring 150 is formed through the container mounting plate, and the first mounting ring and the second mounting ring are connected by a rotational locking connection between the ring walls. The first mounting ring comprises a first ring opening 51 and a first ring base 53, and a seal groove 52 is provided between the first ring opening and the first ring base, and the container seal ring 6 encloses both opposing sides of the first ring opening. A positioning block 56 is provided on the first ring base 53, and a container locking groove 156 is provided on the second mounting ring 150. The container locking groove is L-shaped and has a first groove opening and a second locking groove that communicate with each other. Locking is completed when the positioning block 56 enters through the opening of the first groove opening and enters the second locking groove. A positioning projection is provided on the positioning block 56, and a recess is provided on the second locking groove corresponding to the positioning projection. To attach the raw material container, force must be applied by hand, and when the locking reaches the predetermined position, the positioning projection retracts into the recess. Similarly, when it is necessary to remove the raw material container from the housing, force must be applied to disengage the positioning projection from the recess in order to separate it from the second locking groove. The container seal ring 6 comprises an inner seal ring 61 and an outer seal member 62. The inner seal ring 61 is sandwiched between the first mounting ring and the evaporator mounting cylinder, and the outer seal member 62 is sandwiched between the first mounting ring and the second mounting ring. The outer seal member 62 is L-shaped, and a flange 622 is provided at one end of the L-shaped seal member, which presses against the outer wall of the evaporator mounting cylinder 2. An attachment head 621 is provided at the other end of the L-shaped sealing member. One end of the attachment head 621 fits into the sealing groove 52, and the other end fits into the gap formed by the second mounting ring 150 and the first ring base 53.
[0011] The housing is provided with a condensation water recovery section 105, and the condensation water recovery section is provided with a water guide hole 107. The water guide hole is used to guide condensation water from the outer wall of the raw material container to a water tray inside the housing or to the outside of the housing. The inner wall of the raw material container is provided with baffle ribs 17, which are used to prevent the material inside the raw material container from rising along the container wall when the stirring blades rotate. The side wall of the housing connected to the condensation water recovery section is provided with support projections 106, and the front wall of the housing connected to the condensation water recovery section is provided with a third locking groove 108 with an open top. The outer wall of the raw material container is provided with a container hook 13 and an arc-shaped rib 14. The container hook engages with the third locking groove, and the arc-shaped rib 14 is supported on the support projection 106. The container hook 13 is L-shaped and has a stopper plate 131, and when attaching the raw material container, the second mounting ring 150 is fitted towards the evaporator mounting cylinder until it approaches the container mounting seat 5. At this time, the container hook 13 is positioned on the opening of the third locking groove 108. The container hook 13 is inserted through the opening of the L-shaped third locking groove by gripping the raw material container, and rotation is completed when it comes into contact with the stopper of the third locking groove. A fourth hook 55 is provided on the base plate 54, and a mounting plate hook 155 is provided on the container mounting plate 15. Both the fourth hook 55 and the mounting plate hook 155 have L-shaped hook plates, and the structure of the fourth hook 55 is the same as that of the container hook 13, and the fourth hook 55 also has a stopper plate. Therefore, when the raw material container is rotated and locked to the container mounting seat 5, the fourth hook 55 and the mounting plate hook 155 interlock with each other to form a stopper structure, rotating the raw material container to a predetermined position.
[0012] A notch is provided in the top wall of the raw material container, and the notch has a roughly rectangular structure. A vertical wall 90 extends vertically along the edge of the notch to form an input compartment 9. A lid (not shown) is provided at the top of the input compartment. The vertical wall 90 has a pair of inner vertical walls 902 on the inside of the raw material container, and a splash guard plate 91 is provided on the notch, which is the bottom of the input compartment 9. The first side of the splash guard plate is connected to the base 901 of the input compartment, the second side of the splash guard plate extends diagonally downward and is not connected to the vertical wall 90, and the left and right sides of the splash guard plate are connected to the inner vertical walls 902, thereby forming a side input opening 11 below the input compartment. The second side is on the opposite side of the first side, and the direction from the first side to the second side coincides with the direction in which the stirring blades drive and rotate the material in the raw material container.
[0013] As shown in Figure 5, a protruding chamber 12 is provided at the bottom of the front wall 1a of the raw material container, the upper wall 121 of the protruding chamber 12 has a slope, and a spout is provided on the front panel 122 of the protruding chamber 12. A switch seat 16 is provided on the front panel 122, and the dispensing valve switch 3 is mounted on the switch seat 16. When in use, the dispensing valve switch 3 can be opened by operating the handle 31. When the frozen drink machine is in operation, the beverage liquid is added to the raw material container 1 through the input port, and the frozen drink is discharged from the spout under freezing and stirring conditions. The dispensing valve switch includes a handle and a sealing lid 8. The handle is divided into a rotatable handle section 31 and a connecting wall 32 extending from the handle hinge shaft hole 33 to both sides. The handle is attached to the switch seat 16 by the hinge shaft passing through the hinge shaft hole 33. The sealing lid comprises a lid plate, a sealing pad 80, and a return torsion coil spring 84. The lid plate is divided into a first end and a second end extending outwards from the lid plate hinge shaft hole 83. The free end of the connecting wall 32 presses against the first end 82 of the lid plate, and the sealing pad is attached to the second end 81 of the lid plate. The return torsion coil spring contacts the second end 81 of the lid plate and the front wall 122 of the raw material container, respectively, thereby providing a biasing force that closes the spout relative to the second end of the lid plate. Referring to Figure 9, when the rotating handle is pulled outwards, the connecting wall 32 applies pressure to the first end of the lid plate, causing the lid plate to rotate, the sealing pad 80 to move away from the spout, and thus the spout opens. A sealing pad seat 811 is provided on the second end 81 of the lid plate, and the sealing pad 80 is mounted on the sealing pad seat. Referring to Figure 9, the first end 82 of the cover plate is curved outward in an arc shape, and a convex edge is provided on the surface of the connecting wall 32 that contacts the first end of the cover plate, allowing the handle operation to be performed with less force.
[0014] The upper wall 121 of the protruding chamber 12 utilizes its own gradient to move the frozen drink that has not been discharged in a timely manner from the pouring outlet towards the rear end 1b of the raw material container, preventing the frozen drink from gathering above the front wall 1a of the raw material container and condensing into a lump, and reducing the pressure received by the front wall 1a of the raw material container. The top of the raw material container 1 has an arch-shaped structure. The rear end 1b of the raw material container and the front wall 1a of the raw material container are installed opposite to each other. The projected area of the front wall 1a of the raw material container is slightly smaller than the projected area of the rear end 1b of the raw material container. The raw material container slightly contracts from the rear end 1b of the raw material container towards the front wall 1a of the raw material container, and the raw material container 1 forms a shape that contracts towards the pouring outlet. An extrusion head 41 is provided on the stirring blade 4 and faces the base 42. When the evaporator is attached to the raw material container 1, the extrusion head 41 of the stirring blade 4 enters the protruding chamber 12 and is connected to the pouring outlet. When the frozen drink machine is in operation, through the rotation of the stirring blade 4, the extrusion head 41 pushes out the formed frozen drink from the pouring outlet.
