Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, and in particular to an ice scraping structure for an ice maker evaporator. Background Technology

[0002] Chinese Patent Document No. CN218495421U, published on February 17, 2023, discloses an evaporator and ice maker with a flow-guiding structure. The evaporator includes a main body, which comprises an inner cylinder and an outer cylinder. A cavity for refrigerant flow is formed between the inner and outer cylinders. A refrigerant inlet is provided at the upper end of the cavity. A guide member for guiding the refrigerant to flow along the outer wall of the inner cylinder is provided inside the cavity, and the guide member is located below the refrigerant inlet. During the ice-making process, when the ice blade (spiral propulsion component) scrapes the ice in the inner cylinder, the smooth surface of the inner cylinder results in insufficient friction, causing the ice in the entire inner cylinder to slip and thus fail to be scraped off, leading to the formation of a frozen cylinder.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide an ice scraping structure for an ice maker evaporator that is simple in structure, prevents ice from slipping, ensures smooth ice dispensing, has a reasonable layout, and is highly practical, in order to overcome the shortcomings of the prior art.

[0005] An ice scraping structure for an ice maker evaporator designed for this purpose includes an inner barrel and an ice blade rotatably disposed inside the inner barrel. The characteristic feature is that a threaded portion is provided on the inner wall of the inner barrel, and the ice blade cooperates with the threaded portion when rotating to scrape off ice blocks inside the inner barrel.

[0006] The threaded portion is recessed or protruding on the inner wall of the inner barrel.

[0007] The ice skate has a spiral blade that engages with the threaded part when the skate rotates.

[0008] The threaded part is located on the inner wall of the inner barrel at the height position corresponding to the spiral blade.

[0009] The top of the inner barrel is equipped with an ice extrusion head, which has an ice outlet hole. The threaded part and the spiral blade are located near the ice outlet hole.

[0010] The threaded section and the spiral blade are located at the top of the inner barrel.

[0011] The threaded part has the opposite helical direction to the helical cutting edge.

[0012] A gap is left between the threaded part and the spiral cutting edge.

[0013] The threaded part has a helical groove.

[0014] The threaded section extends upwards to the top of the inner tub.

[0015] The ice scraping structure of the ice maker evaporator of this utility model has a threaded part on the inner wall of the inner barrel. When the ice blade rotates, it cooperates with the threaded part to scrape off the ice in the inner barrel. The threaded part can increase the friction of the inner wall of the inner barrel, prevent the ice in the inner barrel from slipping, and thus make the ice blade scrape off the ice smoothly, thereby making the ice discharge of the evaporator smoother.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1-6 The ice scraping structure of the evaporator of this ice maker includes an inner barrel 1 and an ice blade 2 that is rotatably disposed inside the inner barrel 1. A threaded part 3 is provided on the inner wall of the inner barrel 1. When the ice blade 2 rotates, it cooperates with the threaded part 3 to scrape off the ice blocks inside the inner barrel 1.

[0024] The threaded portion 3 is recessed or protruding on the inner wall of the inner barrel 1. In this embodiment, the threaded portion 3 is recessed on the inner wall of the inner barrel 1.

[0025] The ice skate 2 is equipped with a spiral blade 4. When the ice skate 2 rotates, the spiral blade 4 and the threaded part 3 cooperate with each other to scrape off the ice blocks in the inner barrel 1.

[0026] The threaded part 3 is located on the inner wall of the inner barrel 1 at a height corresponding to the spiral blade 4.

[0027] The top of the inner barrel 1 is provided with an ice squeezing head 5, and the ice squeezing head 5 is provided with several ice outlet holes 6 in a ring. The threaded part 3 and the spiral blade 4 are located near the ice outlet holes 6. After the ice block in the inner barrel 1 is scraped off, the spiral blade 4 pushes the ice block to squeeze the ice squeezing head 5, so that the ice block is squeezed out from the ice outlet holes 6 of the ice squeezing head 5.

[0028] The threaded part 3 and the spiral blade 4 are located on the upper part of the inner barrel 1.

[0029] The spiral direction of the threaded part 3 is opposite to that of the spiral blade 4, which further increases the friction when scraping ice and improves the ice scraping effect.

[0030] A gap 7 is left between the threaded part 3 and the spiral blade 4.

[0031] The threaded part 3 is a helical groove.

[0032] The threaded portion 3 extends upward to the top of the inner barrel 1.

[0033] A notch 8 is provided between two adjacent ice outlet holes 6, and the two adjacent ice outlet holes 6 are connected through the notch 8. This structure allows ice blocks to be squeezed into the ice outlet holes 6, and the ice blocks in the ice outlet holes 6 with more ice blocks will move to the ice outlet holes 6 with fewer ice blocks through the notch 8, making the ice discharge from each ice outlet hole 6 more uniform. As a result, the ice blocks pushed out from each ice outlet hole 6 are all shaped and have the same hardness.

[0034] The lower end of the ice blade 2 is connected to the gearbox assembly, which is connected to the motor. The upper end of the ice blade 2 is connected to the ice-scraping head 9. The top of the ice-scraping head 9 is provided with an elliptical actuating part 10, and the bottom of the actuating part 10 is provided with an inclined surface 11. When the ice blade 2 rotates, it drives the ice-scraping head 9 to rotate. When the ice is squeezed out from the ice outlet 6, the inclined surface 11 is used to break the ice. At the same time, the actuating part 10 pushes the ice onto the ice-filled basket to prevent too much ice from remaining on the top of the inner bucket 1. By breaking the ice with the inclined surface 11 of the ice-scraping head 9, the length of the ice is made more uniform and better looking.

[0035] A bearing 12 is fixedly installed inside the inner barrel 1, and a limiting step 13 is provided on the ice skate 2. The ice skate 2 presses against the bearing 12 through the limiting step 13, thereby effectively fixing the ice skate 2. This makes it less likely for the ice skate 2 to deform or move downwards when working, thereby reducing the force on the gearbox assembly and preventing the ice skate from pressing down on the gearbox assembly and causing damage to the gearbox assembly, thus ensuring the normal operation of ice making.

[0036] The top of the ice skate 2 is provided with a limiting engagement part 14, and the ice skate 2 is positioned on the extrusion head 5 through the limiting engagement part 14.

[0037] A base 15 is fixedly installed at the bottom of the inner tub 1. A positioning groove is provided on the base 15, and the bearing 12 is positioned and installed on the positioning groove.

[0038] Bearing 12 is a tapered thrust bearing, which can withstand heavy axial loads, thus effectively preventing the ice skate 2 from moving downwards during operation.
