Description

TECHNICAL FIELD

[0001] The utility model relates to refrigeration technical field, concretely relates to an ice maker evaporator. BACKGROUND

[0002] The ice maker is a kind of refrigeration equipment for heat exchange between water and refrigerant, and the ice maker mainly includes ice-making evaporator and refrigeration system, and the refrigeration system is used to provide the cold quantity required for ice-making evaporator, and the ice-making evaporator is generally divided into spray type, immersion type and extrusion type according to different ice-making principles, wherein the extrusion type ice maker generally includes evaporator and spiral ice scraping mechanism, the spiral ice scraping mechanism pushes up the ice formed in the evaporator by screw rod and extrudes from ice extruding port to form ice bar, and under the action of ice breaking assembly, ice bar is broken into granular ice.

[0003] According to the above, the extrusion type ice maker is to make water condense on the cylinder wall to form ice layer after being cooled, and the ice layer is scraped by spiral ice scraping mechanism when rotating, and the scraped ice is transported from ice extruding port under the pushing action of spiral ice scraping mechanism.

[0004] The ice breaking assembly is installed outside the spiral ice scraping mechanism in the extrusion type ice-making evaporator disclosed by CN222123553U, the ice breaking assembly is composed of middle connecting piece and ice breaking rod, one end of the middle connecting piece is fixed with the cutter shaft in the spiral ice scraping mechanism, the other end of the middle connecting piece is fixed with the ice breaking rod, when the spiral ice scraping mechanism rotates, the ice breaking assembly rotates with the spiral ice scraping mechanism, and the ice breaking rod applies pushing force to the ice bar from the circumferential surface of the ice bar in the rotating process, so that the ice bar is broken, and granular ice is obtained.

[0005] For the above structure, since there are multiple ice extruding ports on the evaporator, ice bars can be output simultaneously from these ice extruding ports during ice-making, however, the ice breaking rod cannot apply pushing force to multiple ice bars simultaneously, that is, the ice breaking rod can only apply pushing force to each ice bar one by one in the rotating process, and this mode will cause the length of each granular ice to be inconsistent. UTILITY MODEL CONTENTS

[0006] The utility model provides an ice maker evaporator, and the utility model can make the length of obtained granular ice substantially consistent.

[0007] The technical solutions for solving the above technical problems are as follows:

[0008] The ice maker evaporator comprises a lower seat, a cylinder, an upper seat, an input pipe, a refrigeration unit, a spiral ice scraping mechanism, one end of the cylinder is fixed with the lower seat, the other end of the cylinder is fixed with the upper seat, the upper seat is provided with ice outlet holes penetrating the axial end face of the upper seat, the input pipe is connected with the cylinder, the refrigeration unit is arranged on the outer circumferential surface of the cylinder, a part of the spiral ice scraping mechanism is located in the cylinder, the spiral ice scraping mechanism is rotationally matched with the lower seat, the spiral ice scraping mechanism is also rotationally matched with the upper seat, and the ice maker evaporator also comprises a blocking assembly matched with the spiral ice scraping mechanism to extrude the ice output from the ice outlet holes to break the ice.

[0009] Since the spiral ice scraping mechanism pushes the ice formed in the cylinder from the lower to the upper, the ice is output from the ice outlet holes, and since the pushing force generated by the spiral ice scraping mechanism on the ice is continuous, when the ice is blocked by the blocking assembly, the ice strips of each ice outlet hole are broken into granular ice with substantially consistent lengths after reaching the same height, and since the ice strips output from the multiple ice outlet holes can be extruded by the spiral ice scraping mechanism and the blocking assembly, the lengths of the ice strips after being broken are substantially consistent, so that the obtained ice granules are relatively uniform.

[0025] The lower seat 1 includes a base 1a and a sealing assembly, the sealing assembly is in cooperation with the base 1a, and the spiral ice scraping mechanism is inserted into the sealing assembly and in rotational cooperation with the sealing assembly. The sealing assembly includes a first sealing sleeve 1b, a second sealing sleeve 1c and a spring 1d, the first sealing sleeve 1b is sleeved on one end of the spiral ice scraping mechanism and fixed with the spiral ice scraping mechanism, the knife shaft 3 is provided with a positioning step 3a, the first sealing sleeve 1b is sleeved on the knife shaft 3 and fixed with the knife shaft 3, the knife shaft 3, the first sealing sleeve 1b and the positioning step 3a cooperate, for example, the first sealing sleeve 1b abuts against the positioning step 3a, the second sealing sleeve 1c is fixed with the base 1a, one end of the spiral ice scraping mechanism is in clearance cooperation with the second sealing sleeve 1c, the spring 1d is sleeved on the first sealing sleeve 1b, one end of the spring 1d is in cooperation with the spiral ice scraping mechanism, one end of the spring 1d abuts against the positioning step 3a, the other end of the spring 1d is in cooperation with the first sealing sleeve 1b, and the tension generated by the spring 1d keeps the axial end faces of the first sealing sleeve 1b and the second sealing sleeve 1c in close contact.

[0026] The sealing assembly further includes a first wear-resistant component 1e and a second wear-resistant component 1f, the first wear-resistant component 1e is in cooperation with the first sealing sleeve 1b, and the second wear-resistant component 1f is in cooperation with the second sealing sleeve 1c, the axial end faces of the first wear-resistant component 1e and the second wear-resistant component 1f are in close contact. An annular groove is provided on the axial end face of the second sealing sleeve 1c, and the first wear-resistant component 1e and the second wear-resistant component 1f are installed in the second annular groove.

[0027] The upper seat 5 is provided with ice outlet openings 5a penetrating the axial end faces of the upper seat 5, when the knife shaft 3 rotates, the spiral scraper 4 pushes the ice formed in the cylinder 2 from bottom to top, under the continuous force, the ice is output from the ice outlet openings 5a. In this embodiment, the number of the ice outlet openings 5a is six, the shape of the ice outlet openings 5a can be various forms, for example, it can adopt a fan shape, it can also adopt a circular hole, it can also adopt a rectangular or polygonal shape, etc.

[0028] The input pipe 6 is connected with the cylinder 2, the refrigeration unit 10 is arranged on the outer circumferential surface of the cylinder 2, the input pipe 6 is used for inputting water into the cylinder 2, and the input pipe 6 is arranged at the lower part of the cylinder 2. The refrigeration unit 10 condenses the water input into the cylinder 2 by the input pipe 6 into ice. In this embodiment, the refrigeration unit 10 adopts the structure of the bellows in CN222123553U, and the specific structure is not described here. The bellows in the refrigeration unit can also be replaced by a cylindrical sleeve or a spiral coil.

[0029] The blocking assembly 7 cooperates with the spiral ice scraping mechanism to extrude the ice output from the ice outlets 5a to break the ice. The blocking assembly 7 is fixed with the upper seat 5 or the spiral ice scraping mechanism. Since the spiral ice scraping mechanism pushes the ice formed in the cylinder 2 upward from the bottom, the ice is output from the ice outlets 5a. Since the pushing force of the spiral ice scraping mechanism on the ice is continuous, when the ice is blocked by the blocking assembly 7, the ice strips output from each ice outlet are broken into ice particles of the same length after reaching the same height. For example, the ice strips output from the first ice outlet are broken into ice particles of the first length when reaching the first height at the first time, and the ice strips output from the second ice outlet are broken into ice particles of the first length when reaching the first height at the second time. Although the first time is not consistent with the second time, the ice strips output from the two ice outlets can be broken into ice particles of substantially the same length. Therefore, the lengths of the ice strips broken by the spiral ice scraping mechanism and the blocking assembly 7 are substantially the same, so that the obtained ice particles are relatively uniform.

[0030] The blocking assembly 7 includes an intermediate connecting part 7a and a blocking part 7b for blocking the ice. The intermediate connecting part 7a is fixed with the upper seat 5 or the spiral ice scraping mechanism. The diameter of at least a part of the blocking part 7b is greater than the diameter of the intermediate connecting part 7a. After the blocking part 7b is fixed with the intermediate connecting part 7a, since the intermediate connecting part 7a is located between the upper seat 5 and the blocking part 7b, the first spacing L1 is formed between one end of the blocking part 7b and the ice outlet 5a, and the first spacing L1 is used for determining the length of the ice strip. The intermediate connecting part 7a and the blocking part 7b both have a hollow structure, which can reduce the material consumption of the blocking assembly 7 and save costs.

[0031] The plurality of ice outlets 5a are arranged around the intermediate connecting part 7a, i.e., the intermediate connecting part 7a is located in the middle of the ice outlets 5a, so that the ice outlets 5a are uniformly distributed around the blocking assembly 7, and thus the ice strips output from the ice outlets 5a can be blocked by the blocking assembly 7.

[0032] The blocking component 7b is a cone or a cylinder, and in this embodiment, the blocking component 7b is preferably a circular cone. When the end of the ice strip abuts against the conical surface of the blocking component 7b, the ice strip is moved along the conical surface due to the conical surface of the blocking component 7b, and the ice strip is broken after being blocked by the conical surface. Thus, the ice strip can be prevented from being partially crushed due to excessive extrusion force during extrusion, and the blocking component 7b in the form of a cone can maintain the integrity of the broken ice strip.

[0033] The blocking component 7b is projected onto the axial end surface of the upper seat 5, and the projection covers at least a portion of each ice outlet 5a. That is, as viewed from the top (Fig. 4), Figure 3 ), the blocking component 7b covers at least a portion of each ice outlet 5a, thereby ensuring that the ice strip output from each ice outlet 5a is blocked by the blocking component 7b.

[0034] Embodiment 2

[0035] As Figure 4 and Figure 5 , the differences between this embodiment and Embodiment 1 are as follows:

[0036] The blocking assembly 7 is fixed with the spiral ice scraping mechanism. In this embodiment, one end of the intermediate connecting component 7a is fixed with the knife shaft 3, and the other end of the intermediate connecting component 7a is fixed with the blocking component 7b. The center of the blocking assembly 7 and the center of the knife shaft 3 are located on the same straight line. When the knife shaft 3 rotates, the blocking assembly 7 rotates with the knife shaft 3, but the axis of the blocking assembly 7 is always located in the middle of the plurality of ice outlets 5a, and thus does not affect the blocking effect of the blocking assembly 7 on the ice strips output from each ice outlet 5a.

[0037] The ice breaking and pushing rod 8 is further included for pushing the broken ice. The ice breaking and pushing rod 8 is fixed with the blocking assembly 7. The broken ice particles will accumulate, and when the ice particles accumulate, the ice breaking and pushing rod 8 will move the accumulated ice particles, i.e., push the ice particles to the output port (not shown in the figure) of the ice maker. Thus, the ice outlets 5a will not accumulate too many ice particles, and the ice particles will be automatically output from the output port.
