An ice making machine suitable for making transparent ice cubes

Abstract

An ice maker suitable for making transparent ice cubes includes an ice storage bucket, a bracket, a water spray assembly, an ice making assembly, and a control module. The water spray assembly includes a water distribution pipe, a nozzle, and a hose. The ice making assembly includes an ice tray, an ice grid, and a refrigerant assembly. Water is sprayed into the ice grid through the nozzle, and the water in the ice grid will immediately condense into a layer of ice and condense layer by layer until the ice grid is filled. There is an acute angle between the plane where the ice tray is located and the plane where the bracket is located. The plane where the ice making assembly is located is parallel to the plane where the water spray assembly is located, so that the finished ice will not hit the water spray assembly when it falls, so there is no need to flip the water spray assembly through a motor, thereby improving the ice making efficiency. Since the nozzle is no longer vertically arranged, but tilted, it can avoid the deposition of impurities in the water, thereby extending the life of the nozzle.

Description

Technical Field

[0001] The invention relates to the technical field of refrigeration equipment, and in particular to an ice making machine suitable for making transparent ice cubes. Background Art

[0002] Ice trays are essential tools in the field of ice making. Ice trays are divided into ordinary ice trays, water-flowing ice trays, spraying ice trays, etc. Among them, spraying ice trays are mostly placed horizontally when making ice, and the ice tray's ice grid faces downward and is located above the water pipe. Water is sprayed into the ice grid of the ice tray through the spray nozzle of the water pipe, and the water entering the ice grid condenses into ice by cooling during the process of water spraying to the ice tray. After the ice grid is filled, the ice tray is heated to make the ice fall off.

[0003] In the prior art, since the spray ice tray sprays water into the ice-making grid above the water pipe through the spray nozzle of the water pipe, and the diameter of the spray nozzle is generally small, the nozzle is easily blocked by impurities in the water, and during the de-icing process, the water pipe and the nozzle need to be moved away by a motor to prevent ice cubes from hitting the water pipe when falling, which is troublesome and affects the efficiency. In addition, the motor is easily damaged in a humid environment, thereby affecting the efficiency of ice making. Summary of the invention

[0004] In view of this, the present invention provides an ice making machine suitable for making transparent ice cubes to solve the above technical problems.

[0005] An ice making machine suitable for making transparent ice cubes comprises an ice storage bucket, two brackets arranged at intervals on the ice storage bucket, a water spray assembly arranged on one of the two brackets, and an ice making assembly arranged on the other bracket. The two brackets are respectively arranged at one end of the ice storage bucket and are respectively located on both sides of the ice storage bucket. The water spray assembly comprises a water distribution pipe arranged obliquely on one of the brackets, and a plurality of spray heads arranged on the water distribution pipe. One end of the water distribution pipe is arranged on one of the brackets, and the other end is arranged on the ice storage bucket and is located between the two brackets. The water spraying direction of the spray head is toward the ice making assembly, and the water spraying amount of the spray head gradually increases from one end close to the ice storage bucket to the direction away from the other end of the ice storage bucket. The ice making assembly comprises an ice tray arranged obliquely on the other bracket, and a plurality of rows of ice grids arranged on the ice tray. There is an acute angle between the plane where the ice tray is located and the plane where the bracket is located, and the plane where the ice tray is located is parallel to the plane where the water distribution pipe is located and is arranged at intervals. The ice tray faces the nozzle, and each of the ice trays corresponds to the position of each of the nozzles one by one. The water spraying assembly also includes a plurality of hoses respectively arranged on the nozzles, and the hoses are located between the water distribution pipe and the ice-making assembly. One end of the hose is sleeved on the nozzle, and the other end can bend and droop freely. The nozzle sprays water to straighten the bent hose, and the straightened hose faces the ice-making assembly and does not touch the ice-making assembly. When defrosting, the nozzle stops spraying water, so that the hose bends and droops freely, thereby not blocking the ice cubes from falling and preventing the ice cubes from hitting the hose.

[0006] Furthermore, an ice inlet and an ice outlet are respectively provided at two ends of the ice storage bucket, and the size of the ice inlet is larger than the ice outlet.

[0007] Furthermore, the ice maker suitable for making transparent ice cubes also includes a control module arranged outside the ice storage bucket, and the control module is used to control the opening and closing of the ice outlet.

[0008] Furthermore, the spacings between the nozzles in adjacent columns or rows are equal.

[0009] Furthermore, the length of the hose is 25 cm to 30 cm.

[0010] Furthermore, the angle between the plane where the ice tray is located and the plane where the bracket is located is 10 to 20 degrees.

[0011] Furthermore, the ice-making assembly further includes a refrigerant assembly disposed on the ice tray, and the refrigerant assembly is located between the ice tray and the bracket on which the ice-making assembly is disposed.

[0012] Compared with the prior art, the ice making machine for making transparent ice cubes provided by the present invention is designed by designing the setting angles of the water spray assembly and the ice making assembly. Specifically, the ice making assembly includes an ice tray obliquely arranged on one of the brackets, multiple rows of ice grids arranged on the ice tray, and a refrigerant assembly arranged on the ice tray. There is an acute angle between the plane where the ice tray is located and the plane where the bracket is located, and the angle of the acute angle is 10 to 20 degrees. The plane where the ice making assembly is located is parallel to the plane where the water spray assembly is located, so that the finished ice will not hit the water spray assembly when it falls, so there is no need to flip the water spray assembly through a motor, thereby improving the ice making efficiency. The water spray assembly includes a water distribution pipe obliquely arranged on another of the brackets, multiple rows of nozzles arranged on the water distribution pipe, and multiple hoses respectively arranged on the nozzles. The positions of the nozzles and the ice grids correspond one to one, and each nozzle cover is provided with the hose. Since the nozzles are no longer arranged vertically, but are arranged obliquely, the deposition of impurities in the water can be avoided, thereby extending the life of the nozzles. In addition, since the ice tray is set at an angle, when the water sprayed to the ice grid at a high place is no longer frozen, it will flow downward and flow to the ice grid below, which can not only improve the ice making efficiency, but also fill the ice grid below to make more square ice cubes.

[0017] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0018] like Figures 1 to 4As shown, it is a schematic diagram of the structure of an ice maker for making transparent ice cubes provided by the present invention. The ice maker for making transparent ice cubes includes an ice storage bucket 10, two brackets 20 arranged on the ice storage bucket 10 at intervals, a water spray assembly 30 arranged on one of the two brackets 10, an ice making assembly 40 arranged on the other bracket 10, and a control module 50 arranged on the ice storage bucket 10. It can be imagined that the ice maker for making transparent ice cubes also includes some other functional modules, such as assembly components, installation components, water pumps, and electrical connection components, etc., which are well known to those skilled in the art and will not be repeated here.

[0019] The ice storage bucket 10 is used to carry the bracket 20, the water spray assembly 30, the ice making assembly 40, and the control module 50 and is used to store ice cubes. An ice inlet 11 and an ice outlet 12 are respectively provided at both ends of the ice storage bucket 10, and the size of the ice inlet 11 is larger than the ice outlet 12. The ice inlet 11 is used to receive ice cubes dropped from the ice making assembly 40, and the ice cubes stored in the ice storage bucket 10 are dropped out from the ice outlet 12 by opening the ice outlet 12, which is a prior art and will not be described in detail here.

[0020] The two brackets 20 are respectively arranged at one end of the ice storage bucket 10 provided with the ice inlet 11 and are respectively located on both sides of the ice inlet 11. The brackets 20 are used to set the water spray assembly 30 and the ice making assembly 40. It can be understood that the two brackets 20 can be part of the entire frame of the ice maker, which will not be repeated here.

[0021] The water spray assembly 30 includes a water distribution pipe 31 obliquely disposed on one of the brackets 20 , a plurality of spray heads 32 disposed on the water distribution pipe 31 , and a plurality of hoses 33 respectively disposed on the spray heads 31 .

[0022] One end of the water diversion pipe 31 is disposed on one of the brackets 20, and the other end is disposed on the ice storage bucket 10 and is located between the two brackets 20. The water diversion pipe 31 is connected to a water inlet pipe (not shown), and the water diversion pipe 31 is used to divert water. Water is pumped by a water pump (not shown) and flows into the water diversion pipe 31 through the water pipe, and then diverted through the water diversion pipe 31 under the water pressure provided by the water pump.

[0023] The nozzles 32 are arranged in an array on the water distribution pipe 31, and the spacing between the nozzles 32 in adjacent columns or rows is equal. The water spraying direction of the nozzles 32 is toward the ice-making assembly 40, so that the water after diversion in the water distribution pipe 31 can be sprayed toward the ice-making assembly 40 through the nozzles 32. It can be imagined that the diameter of the nozzles 32 can be set according to actual needs, such as the flow rate of water, the head of the water pump, etc. The water spraying amount of the multiple nozzles 32 gradually increases from one end close to the ice storage bucket 10 to the other end away from the ice storage bucket 10, and the reason will be explained below in conjunction with the ice-making assembly 40.

[0024] One end of the plurality of hoses 33 is respectively sleeved on the nozzles 32, and the other end is free to bend and droop. The hose 33 is located between the water distribution pipe 31 and the ice-making assembly 40. When water is sprayed from the nozzle 32, the bent hose 33 is straightened under the action of water pressure. The straightened hose 33 faces the ice-making assembly 40 and does not touch the ice-making assembly 40, so as to prevent the water sprayed from the plurality of nozzles 32 from interfering with each other, so that the water can be sprayed to the ice-making assembly 40 more accurately. At the same time, since the hose 33 is bent under the action of gravity when water is not sprayed, the interference caused by the hose 33 to the ice-making assembly 40 when it is de-icing can be reduced, because the distance between the hose 33 and the ice-making assembly 40 is not very large, because if it is too large, a greater water pressure is required, and if the water pressure is too large, splashing will be formed, which will not only cause water waste, but also affect the life of other mechanisms such as motors. When the ice making assembly 40 finishes making ice and is defrosting, the spray head 32 stops spraying water, so that the hose 33 is bent and droops freely, so as not to block the ice cubes from falling and prevent the ice cubes from hitting the hose 33. The length of the hose 33 is 25-30 cm, which can be set according to the distance between the ice making assembly 40 and the water spray assembly 30.

[0025] The ice-making assembly 40 includes an ice tray 41 obliquely disposed on another of the brackets 20 , a plurality of rows of ice cubes 42 disposed on the ice tray 41 , and a refrigerant assembly 43 disposed on the ice tray 41 .

[0026] The ice tray 41 is tiltedly arranged on the bracket 20, and there is an acute angle between the plane where the ice tray 41 is located and the plane where the bracket 20 is located, and the angle of the acute angle is 10 to 20 degrees. In this embodiment, the acute angle is 17 degrees. The plane where the ice tray 41 is located is parallel to the plane where the water distribution pipe 31 is located and is arranged at intervals, so that it is convenient for the water spraying assembly 30 to spray water into the ice tray 42, and the ice made by the ice making assembly 40 will not hit the water spraying assembly 30 when it falls.

[0027] A plurality of ice trays 42 are arranged in an array on the ice tray 41, and the spacing between the ice trays 42 in adjacent columns or rows is equal. The ice trays 42 face the nozzles 32, and each of the ice trays 42 corresponds to the position of each of the nozzles 32, so that each of the nozzles 32 can accurately spray water into the corresponding ice trays 42. In the process of spraying the water from the nozzles 32 into the ice trays 42, a portion of the water in the ice trays 42 will condense into a layer of ice under the action of the refrigerant assembly 43, and the water will condense layer by layer through the continuous water spraying of the water spray assembly 30 until the ice trays 42 are filled, thus completing ice making. The water sprayed into the ice trays 42 will immediately condense into a layer of ice, so that the water has little contact time with the air during the freezing process, and each of the ice trays 42 is tilted to facilitate the escape of air in the water, so that the finished ice has fewer bubbles inside and becomes a transparent ice cube. In addition, since the ice tray 41 is tilted, when the water sprayed to the ice grid 42 at the upper position is not frozen, it will flow downward and flow to the ice grid below, which can not only improve the ice making efficiency, but also fill the ice grid 42 below to make more square ice cubes. The water spraying amount of the nozzle 32 at different heights gradually increases from one end close to the ice storage bucket 10 to the other end away from the ice storage bucket 10, which can evenly distribute the water flow in the ice grids 42 at different heights and avoid the phenomenon of different ice making speeds in the ice grids 42 at different heights.

[0028] The refrigerant assembly 43 is disposed on the ice tray 41 and is located between the ice tray 41 and the bracket 20 provided with the ice making assembly 40. A refrigerant is disposed in the refrigerant assembly 43, and the refrigerant absorbs the heat of the water in the ice tray 42 to condense the water into ice, thereby achieving the purpose of making ice. When ice making is completed, the refrigerant assembly 43 will also heat the ice tray 41 to make the ice in the ice tray 42 fall into the ice storage bucket 10. The refrigeration principle and ice removal principle are prior art, and will not be described in detail here.

[0029] The control module 50 is disposed outside the ice storage bucket 10 and is used to control the opening and closing of the ice outlet 12 so that an appropriate amount of ice can be taken out under the control of the user. However, this is a prior art and will not be described in detail here.

[0030] Compared with the prior art, the ice making machine for making transparent ice cubes provided by the present invention is designed by designing the setting angles of the water spray assembly 30 and the ice making assembly 40. Specifically, the ice making assembly includes an ice tray 41 obliquely arranged on one of the brackets 20, multiple rows of ice cubes 42 arranged on the ice tray 41, and a refrigerant assembly 43 arranged on the ice tray 41. There is an acute angle between the plane where the ice tray 41 is located and the plane where the bracket 20 is located, and the angle of the acute angle is 10 to 20 degrees. The plane where the ice making assembly 40 is located is parallel to the plane where the water spray assembly 30 is located, so that the finished ice will not hit the water spray assembly 30 when it falls, so there is no need to flip the water spray assembly 30 by a motor, thereby improving the ice making efficiency. The water spray assembly 30 includes a water distribution pipe 31 obliquely arranged on another of the brackets 20, multiple rows of spray heads 32 arranged on the water distribution pipe 31, and multiple hoses 33 respectively arranged on the spray heads 31. The positions of the nozzles 32 and the ice trays 42 correspond one to one, and each nozzle 32 is sleeved with the hose 33. Since the nozzles 32 are no longer vertically arranged but tilted, the impurities in the water can be prevented from being deposited, thereby extending the life of the nozzles 32. In addition, since the ice tray 41 is tilted, when the water sprayed to the ice tray 42 at a high position is no longer frozen, it will flow downward and flow to the ice tray below, which can not only improve the ice making efficiency, but also fill the ice tray 42 below to make more square ice cubes.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
