Description

Technical Field

[0001] The present invention relates to the technical field of ice makers, and particularly to an evaporator for an ice maker. Background Art

[0002] Chewing ice evaporators on the market all adopt the form of coiled copper tubes or flooded type; for the evaporator of the coiled copper tube type, the copper tube is attached to the stainless steel for heat conduction, and the attachment method can never achieve the effect of direct conduction, so the heat conduction efficiency is much worse; for the flooded type evaporator, because the inside is a large cavity without refrigerant guidance, the refrigerant enters from the bottom of the cavity and directly exits from the top of the cavity, resulting in a lower efficiency of heat conduction to the inner barrel, and a part of the cold energy directly returns to the compressor from the outlet pipe, resulting in poor performance. In addition, when the ice knife pushes the ice cubes to be extruded to the ice extrusion head, and the ice cubes are extruded from the ice outlet holes of the ice extrusion head, a large downward axial thrust will be received, and the axial thrust directly acts on the gearbox, resulting in a large force on the gearbox and easily causing damage to the gearbox.

[0003] Therefore, it is necessary to make further improvements. Summary of the Invention

[0004] The purpose of the present invention is to provide an ice maker evaporator with simple structure, high heat conduction efficiency, uniform refrigeration, good positioning effect and strong practicability to overcome the deficiencies of the prior art.

When the ice knife drives the ice scraper to rotate, the pushing part acts on the squeezed ice cubes.

[0010] It also includes a motor, a gear box assembly, a support frame and a base. The motor drive is connected to the input end of the gear box assembly, and the output end of the gear box assembly is connected to the ice skate. The base is fixed to the bottom of the inner barrel, and the bearing is installed on the base. The base and the gear box assembly are respectively fixed on the support frame. A plurality of positioning claws are arranged in a ring at the bottom of the base, and a plurality of positioning holes are arranged in a ring on the support frame. A positioning ring is arranged on the gear box assembly. After the positioning claws pass through the positioning holes, they are pressed inward against the outer circle of the positioning ring.

[0011] A second gap is provided between two adjacent ice outlet holes, and the two adjacent ice outlet holes are connected through the second gap.

[0012] A threaded portion is arranged on the side wall of the inner cavity, and a spiral blade is arranged on the ice skate. When the ice skate rotates, the spiral blade cooperates with the threaded portion to scrape off ice debris in the inner barrel.

[0029] The present invention will be further described below in conjunction with the drawings and embodiments.

[0030] See Figures 1 - 13The evaporator of the ice maker comprises an outer barrel 1, an inner barrel 2, an ice cutter 3, an ice squeezing head 4 and an ice scooping head 5. The outer barrel 1 is mounted on the upper part of the inner barrel 2. A cavity 6 is formed between the outer barrel 1 and the inner barrel 2. An air inlet pipe 7 for passing a refrigerant into the cavity 6 is provided on the outer barrel 1. The air inlet pipe 7 is connected to the cavity 6. The air inlet pipe 7 is connected to the capillary of the condenser. An inner cavity 8 is provided in the inner barrel 2. A water inlet pipe 9 for passing water into the inner cavity 8 is provided on the inner barrel 2. The water inlet pipe 9 is connected to the inner cavity 8. The ice cutter 3 is rotatably arranged in the inner cavity 8. The ice squeezing head 4 is arranged on the top of the inner barrel 2. A plurality of ice outlet holes 10 connected to the inner cavity 8 are annularly arranged on the ice squeezing head 4. The ice scooping head 5 is arranged on the top of the ice cutter 3 and is located outside the inner barrel 2. When the ice blade 3 rotates, it pushes the ice slag to the ice outlet hole 10 of the ice squeezing head 4, and the ice-shoveling head 5 acts on the ice outlet hole 10 to form ice cubes; when the compressor is started, the refrigerant enters the cavity 6 through the air inlet pipe 7, and the refrigerant evaporates in the cavity 6, and water continues to enter the inner cavity 8 of the inner barrel 2 through the water inlet pipe 9. Under the action of the refrigerant, the water entering the inner cavity 8 instantly freezes into ice slag. At this time, the ice blade 3 rotates to scrape off the ice slag on the inner cavity 8, and the ice blade 3 continues to push the ice slag to the ice squeezing head 4. The ice slag is pushed to the ice outlet hole 10 for shaping, thereby continuously squeezing out strips of ice cubes of a certain shape, and the ice cubes collide with the ice-shoveling head 5, thereby forming granular ice cubes, and the ice-shoveling head stirs the granular ice cubes and pushes the ice cubes into the ice basket. The evaporator is a chewing ice evaporator, which is used in refrigerators.

[0031] The cavity 6 is provided with an annular flow channel 11 which is distributed up and down, a first notch 12 is provided at the bottom of the flow channel 11, and two adjacent flow channels 11 are connected through the first notch 12. The air inlet pipe 7 is located at the bottom of the outer barrel 1, and an exhaust pipe 13 for discharging the refrigerant is provided at the top of the outer barrel 1. The exhaust pipe 13 is connected to the return air pipe of the compressor, and the exhaust pipe 13 is connected to the cavity 6. The air inlet pipe 7 is connected to the flow channel 11 at the bottom of the cavity 6, and the exhaust pipe 13 is connected to the flow channel 11 at the top of the cavity 6. When the evaporator is working, the low-temperature and high-pressure refrigerant enters the cavity 6 from the air inlet pipe 9, and then enters the flow channel 11, and flows upward layer by layer along the flow channel 11 (such as Figure 1 and Figure 7 The refrigerant flows through the top flow channel 11 and then returns to the compressor through the exhaust pipe 13. The flow channel 11 guides the flow of the refrigerant, which is beneficial to the evaporation of the refrigerant and the absorption of cold energy (i.e., the water in the inner cavity 8 absorbs the cold energy of the refrigerant), thereby making the cooling of the inner barrel 2 more uniform.

[0032] The inner wall of the outer barrel 1 is provided with guide ribs 36 distributed up and down. The guide ribs 36 are annular. A flow channel 11 is formed between two adjacent guide ribs 36 . The first notch 12 is provided on the guide rib 36 .

[0033] A bearing 14 is fixedly arranged on the inner cavity 8, and a limiting step 15 is arranged on the ice blade 3. The ice blade 3 presses downward on the bearing 14 through the limiting step 15. When squeezing ice, a very high clearance is required between the ice squeezing head 4 and the ice blade 3. If the clearance is too small, the friction will be too large, and the gear box assembly 23 and the motor 22 will have higher requirements. If the clearance is too large, the ice layer will be too thick and ice cubes cannot be squeezed out. Therefore, a bearing 14 is added to the bottom of the ice blade 3. The downward axial thrust (i.e., reaction force) received by the ice blade when squeezing ice acts on the bearing 14, which can ensure that the clearance between the ice squeezing head 4 and the ice blade 3 is neither too large nor too small, thereby ensuring the quality of the ice.

[0034] A second limiting portion 37 is protruded from the top of the bearing 14, and the limiting step 4 presses downward against the second limiting portion 37, thereby preventing the ice skate 3 from moving downward when working.

[0035] A connecting section 38 is provided at the lower part of the ice blade 3, and a rotating hole 39 is provided on the bearing 14. The connecting section 38 is rotatably connected with the rotating hole 39 to realize the front, back, left and right positioning of the ice blade 3.

[0036] A limiting fitting portion 40 is provided at the top of the ice blade 3, and the ice blade 3 is positioned to the upper limit on the ice squeezing head 5 through the limiting fitting portion 40; when the ice blade 3 rotates, the ice debris on the inner cavity 8 is scraped off, and the ice blade 3 pushes the ice debris to be squeezed onto the ice squeezing head 4, so that ice cubes are squeezed out from the ice outlet hole 10 of the ice squeezing head 4.

[0037] The bearing 14 is a tapered thrust bearing, which can withstand a heavy axial load, thereby effectively preventing the ice skate 3 from moving downward when working.

[0038] The ice blade 3 is provided with a sealing dynamic ring 16 and a sealing fixed ring 17 which are arranged in sequence from top to bottom. A support plate 18 is fixedly arranged on the inner cavity 8. A first limiting portion 19 is arranged on the ice blade 3. The sealing dynamic ring 16 presses upward against the first limiting portion 19. The bottom of the sealing fixed ring 17 is supported on the support plate 18. The bottom of the sealing dynamic ring 16 is supported on the sealing fixed ring 17. The sealing fixed ring 17 is arranged between the support plate 18 and the ice blade 3, which can prevent the water in the inner cavity 8 from leaking out of the inner cavity 8 from the gap between the support plate 18 and the ice blade 3.

[0039] An elliptical moving part 20 is provided on the top of the ice-squeezing head 5, and an inclined surface 21 is provided on the bottom of the moving part 20; when the ice blade 3 rotates, the ice debris is pushed to the ice outlet hole 10 of the ice-squeezing head 4, and the inclined surface 21 acts on the ice cubes formed on the ice outlet hole 10 to squeeze the ice cubes, and when the ice blade 3 drives the ice-squeezing head 5 to rotate, the moving part 20 acts on the squeezed ice cubes; when the ice cubes are squeezed out of the ice outlet hole 10, the inclined surface 21 is used to squeeze the ice, and at the same time, the moving part 20 pushes the ice cubes to the ice basket to prevent too much ice from remaining on the top of the inner bucket 2; by squeezing the ice cubes by the inclined surface 21 of the ice-squeezing head 5, the length of the ice cubes is more uniform and better looking.

[0040] It further includes a motor 22, a gearbox assembly 23, a support frame 24 and a base 25. The motor 22 is drivingly connected to the input end of the gearbox assembly 23, and the output end of the gearbox assembly 23 is connected to the connecting section 38 of the ice skate blade 3. The base 25 is fixed to the bottom of the inner barrel 2 by screws, the bearing 14 is installed on the base 25, and the base 25 and the gearbox assembly 23 are respectively fixed to the support frame 24 by screws. A plurality of positioning claws 26 are annularly arranged at the bottom of the base 25, a plurality of positioning holes 27 are annularly arranged on the support frame 24, and a positioning ring 28 is arranged on the gearbox assembly 23. After the positioning claws 26 pass through the positioning holes 27, they abut against the outer circle of the positioning ring 28 inwardly. In this way, when the gearbox assembly 23 is fixed to the inner barrel 1, the coaxiality of the gearbox assembly 23 and the inner barrel 1 is ensured, and eccentricity is prevented, so as to avoid uneven force on the motor 22 and deformation of the gearbox assembly 23.

[0041] A positioning groove 41 is arranged on the base 25, and the bearing 14 is positioned and installed on the positioning groove 41, so that the bearing 14 is positioned front, rear, left and right inside the inner barrel 2.

[0042] A positioning surface 42 is arranged at the bottom of the positioning groove 41, and the bearing 14 is limited up and down between the limiting step 15 and the positioning surface 42, so that the bearing 14 is positioned up and down inside the inner barrel 2.

[0043] An extrusion section 43 is arranged on the upper part of the ice skate blade 3, and the diameter of the extrusion section 43 is larger than that of the connecting section 38, so as to form a limiting step 15 between the extrusion section 43 and the connecting section 38.

[0044] A second notch 29 is arranged between two adjacent ice outlet holes 10, and two adjacent ice outlet holes 10 are communicated through the second notch 29. This structure enables the ice in the ice outlet hole 10 with more ice to partially move to the ice outlet hole 10 with less ice through the second notch 29 when the ice is squeezed to the ice outlet hole 10, making the ice output of each ice outlet hole 10 more uniform. Thus, the ice pushed out from each ice outlet hole 10 is formed and has the same hardness.

[0045] A threaded portion 30 is arranged on the side wall of the inner cavity 8, and a spiral cutting edge 31 is arranged on the extrusion section 43. When the ice skate blade 3 rotates, the spiral cutting edge 31 cooperates with the threaded portion 30 to scrape off the ice slag in the inner barrel 2, and then the spiral cutting edge 31 pushes the ice slag to be extruded to the ice squeezing head 4, so that the ice blocks are extruded from the ice outlet holes 10 of the ice squeezing head 4.

[0046] The threaded portion 30 is located on the side wall of the inner cavity 8 at the height position corresponding to the spiral cutting edge 31; the threaded portion 30 is a spiral groove; the threaded portion 30 can increase the friction force of the side wall of the inner cavity 8, prevent the ice in the inner barrel 2 from slipping, and further enable the ice skate blade 3 to smoothly scrape off the ice blocks, so that the ice output of the evaporator is smoother.

[0047] One side of the upper part of the ice skate blade 3 is provided with an exhaust hole 32, the top of the ice skate blade 3 is provided with a channel 33, and the ice pushing head 5 is provided with an air outlet hole 34. The inner cavity 8, the exhaust hole 32, the channel 33 and the air outlet hole 34 are connected in sequence to form an exhaust channel. During the ice making process of the evaporator, since there is air in the water in the inner cavity 8, the ice slag will squeeze the air in the water, thus squeezing out the air to form a certain amount of gas. If this gas accumulates more and more, there will be a relatively large air bubble in the inner cavity 8 of the inner barrel 2, which will affect the water inlet of the water inlet pipe 9 and the ice making of the entire inner barrel 2, and then form a frozen cylinder. For example, Figure 2 As shown by the arrow, by providing the exhaust channel, the gas in the inner cavity 8 enters the channel 33 through the exhaust hole 32, then is discharged upward through the channel 33, and finally is discharged out of the inner cavity 8 through the air outlet hole 34. As long as air is formed inside the inner cavity 8, it will be discharged to avoid abnormal ice making.

[0048] The exhaust hole 32 is arranged opposite to the ice pushing outlet point of the ice skate blade 3 to prevent the exhaust hole 32 from being blocked when discharging ice.

[0049] An oil seal 35 is sleeved on the ice skate blade 3. The oil seal 35 is located at the bottom of the bearing 14. The ice skate blade 3 passes through the inner hole 36 of the base 25. The oil seal 35 is arranged between the ice skate blade 3 and the base 25. The base 25 is provided with an installation groove 44, and the oil seal 35 is positioned and installed on the installation groove 44. When the bearing 14 is working, lubricating oil needs to be added. The oil seal 35 can prevent the lubricating oil from leaking out of the inner cavity 8 through the gap between the ice skate blade 3 and the base 25, and can effectively prevent oil leakage, thereby increasing the service life of the bearing 14.
