Description

Technical Field

[0001] The utility model relates to the field of household ice makers, and specifically to a high-efficiency ice-making device based on a telescopic mold. Background Art

[0002] Ice makers, as essential equipment nowadays, are widely used in personal households or beverage stores. The traditional ice-making method is to inject water into a mold and then place the entire mold in a freezer, relying on heat conduction to complete the production of ice cubes. However, when the mold is filled with water, some air bubbles will remain inside the ice grid; and since the traditional ice grid transfers cold from the outside to the inside, a large number of air bubbles will remain in the ice cubes produced by the traditional ice-making method, further reducing the transparency, hardness, and melting time of the ice cubes.

[0003] Therefore, the prior art proposes a device for making ice using an evaporator. Its main working principle is to evenly flow water onto the cooled evaporator, so that the water is cooled by the evaporator to the freezing point and then solidifies into ice; and when the ice cubes reach the required thickness, high-pressure hot gas is injected into the evaporator, and then the contact surface between the ice cubes and the evaporator starts to heat and melt, forming a water film between the ice cubes and the evaporator; with the assistance of the water film, the ice cubes can freely fall into the storage ice tank below by their own gravity.

[0004] Although evaporator ice-making can well improve the transparency, hardness, and melting time of ice cubes, since the water flow is evenly poured onto the metal evaporator, except for the bottom ice layer that directly contacts the evaporator, the ice layers formed later all receive the cold transferred from the underlying ice. And since the heat transfer efficiency of ice cubes is lower than that of metal, it will cause the ice-making speed of ice cubes to slow down.

[0005] At the same time, the number of ice cubes produced by the existing evaporator ice-making machines is determined by the number of its own grids, and most ice-making machines on the market can produce 20 - 50 ice cubes at a time. For household users who only need 6 - 10 ice cubes at a time, there will be many extra ice cubes, and some of the extra ice cubes will require additional energy for refrigerated storage, thus causing waste of energy. Summary of the Invention

[0006] In view of the above technical problems, the utility model provides a high-efficiency ice-making device based on a telescopic mold. By changing the original ice-making method, by splitting the complete ice cubes into a stack composed of several sheet-like ice layers, so that each layer of ice of the ice cubes is directly made by the cold transferred from the refrigeration components on the mold, improving the utilization efficiency of the cold of the refrigeration compressor or the refrigeration semiconductor, greatly shortening the time required for one ice-making; at the same time, the number of ice cubes prepared can be controlled, effectively improving the flexibility of the ice-making quantity.

[0007] To achieve the above technical objectives, the present utility model adopts the following technical means:

[0009] An ice sheet mold, which includes a mold bottom plate and a mold side frame. A refrigeration component for making ice is arranged in the mold bottom plate;

[0011] The mold side frame can be vertically contracted to be flush with the mold bottom plate or located below the mold bottom plate;

[0012] A first horizontal pushing component, which is arranged on one side of the mold bottom plate and is used to push the ice sheet in the horizontal direction;

[0013] A receiving groove, which is used to receive the ice sheet pushed out from the ice sheet mold;

[0014] An extrusion component, which is used to extrude and bond the ice sheets stacked up and down in the receiving groove into a single ice block.

[0015] The ice-making component adopts an evaporator.

[0016] A second water outlet device is arranged above the receiving groove.

[0017] The cross-section of the receiving groove is the same as the cross-section of the inner cavity of the mold side frame; a support plate is arranged at the bottom of the receiving groove, and the support plate is connected to the receiving groove through a vertical lifting component, and the vertical lifting component can control the vertical movement of the support plate;

[0018] The extrusion component includes a pushing top plate and a second horizontal pushing component;

[0019] The pushing top plate is arranged above the side of the receiving groove, and the bottom surface of the pushing top plate is flush with the top surface of the mold bottom plate;

[0020] The second horizontal pushing component is used to horizontally push the pushing top plate towards the receiving groove. A pressing part protruding downward is arranged at the bottom of the pushing top plate, and the pressing part is used to apply a vertical pressing force to the ice sheet when the pushing top plate is located on top of the ice sheet.

[0021] The ice sheet mold is made of hydrophilic material, and the first horizontal pushing component and the pushing top plate are made of hydrophobic material.

[0022] The pressing part is two protruding strips arranged at the bottom of the pushing top plate.

[0023] One end of the protruding strip adjacent to the receiving groove has an arc transition.

[0024] The mold opening accuracy of the mold bottom plate and the mold side frame is a positive and negative tolerance of 0.01-0.02mm.

[0025] The outermost side of the mold side frame is arranged as a heat insulation layer.

[0026] The first water outlet device and the second water outlet device both adopt atomizing nozzles.

[0027] Beneficial effects:

[0028] First, the utility model ice maker divides the ice cubes into a certain number of layers of ice flakes, and each layer of ice flakes is made by directly conducting cold energy from the evaporator. Compared with the traditional ice maker, the subsequent ice layers in the ice cubes are made by conducting cold energy from the bottom ice.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation modes.

[0039] The structural schematic diagram of the ice-making equipment of the present utility model is as Figure 1-7 shown. Embodiment 1

[0040] Referring to Figure 1-6 , the ice sheet mold of the ice-making equipment of the present utility model includes a mold bottom plate 1 and a mold side frame 2. A refrigeration component for making ice is arranged in the mold bottom plate 1; the mold side frame 2 is arranged outside the mold bottom plate 1, and the mold side frame 2 wraps the mold bottom plate 1 in a ring shape; a first water outlet device, specifically, an atomizing nozzle 3 can be used for work, which is used to send water to the refrigeration component, and ice sheets are formed in the ice sheet mold after being cooled by the refrigeration component; among them, the common thickness of ice sheets is 2.5-5 mm.

[0041] The mold side frame 2 can contract vertically to be flush with the mold bottom plate 1 or be located below the mold bottom plate 1. Specifically, a threaded rod 22 transmission device can be set. For example Figure 3-4 shown, the threaded rod 22 transmission device includes a threaded rod 22 and a rotating gear 23. The threaded rod 22 is rotatably connected to the bottom of the mold side frame 2, and a rotating gear 23 is sleeved outside the threaded rod 22. A threaded groove is opened on the inner wall of the rotating gear 23, and the rotating gear 23 is driven by the output end of the motor to rotate. Furthermore, after the ice sheet is formed, the motor drives the rotating gear 23 to rotate, and the threaded rod 22 is driven by the rotating gear 23 to spiral downwards. Thus, the mold side frame 2 rotatably connected to the threaded rod 22 also descends synchronously, so that the movement of the ice sheet will not be hindered by the mold side frame 2.

[0042] It also includes a first horizontal pushing component 51, which is arranged on one side of the mold bottom plate 1, and its bottom surface is flush with the top surface of the mold bottom plate 1, and is used to push the ice sheet in the horizontal direction. The components of the first horizontal pushing component 51 include a horizontal pushing component and an ice cube push rod 52. The horizontal pushing component is arranged on the side of the pushing part away from the mold bottom plate 1, and is connected to the ice cube push rod 52 to push the ice cube push rod 52 in the horizontal direction.

[0043] AsFigure 1-4 As shown, specifically, the horizontal pushing component can be composed in various forms. One of them can be the use of a threaded screw rod and a transmission gear. Among them, the threaded screw rod is horizontally arranged through the pushing constraint side wall 4 and is connected to the ice cube pushing rod 52. The screw rod transmission gear is arranged on the pushing constraint side wall 4 and sleeved outside the threaded screw rod. Or, the horizontal pushing component can also directly adopt any telescopic control device with a linear telescopic function, such as an electric telescopic rod or a hydraulic telescopic rod.

[0044] Above the mold bottom plate 1, there is also a pushing constraint side wall 4 with a rectangular frame structure, and the pushing constraint side wall 4 is used to constrain the horizontal pushing trajectory of the ice sheet to keep it stable.

[0045] As Figure 2 and 7 shown, it also includes a receiving groove 61, which is used to receive the ice sheets pushed out from the ice sheet mold. Above the receiving groove 61, there is a second water outlet device, specifically an atomizing nozzle 3; a squeezing part, which is used to squeeze and bond the ice sheets stacked up and down in the receiving groove 61 into one ice sheet. See Figure 7 , and the specific component parts can be the following structure: above the receiving groove 61, there is a squeezing plate, and the squeezing plate is installed by means of a telescopic mechanism with a linear telescopic function, such as a hydraulic telescopic rod or an electric telescopic rod, and is used to squeeze the ice sheets in the receiving groove 61.

[0046] Furthermore, see Figure 1-6 , in order to avoid the situation that the ice sheet adheres to the mold when it is pushed out, in this application, the mold side frame 2 is installed in the installation groove in the middle of the hollow bottom plate 8 with a plurality of strip-shaped grooves 81; among them, the strip-shaped grooves 81 are parallel to the pushing trajectory of the pushing part. Therefore, after the ice sheet is pushed out, it will pass through the hollow bottom plate 8, and because a plurality of strip-shaped grooves 81 are opened on the surface of the hollow bottom plate 8, the contact area between the hollow bottom plate 8 and the ice sheet is small, which can effectively reduce the friction force between the two. By this means, it can play a role in ensuring the integrity of the ice sheet.

[0047] See Figure 3-4 , this utility model considers that when the atomized water flow is sprayed outside the mold side frame 2, ice will also be formed, and this part of the ice will affect the shape of the ice sheet, further affect the shape after the ice sheets are stacked, and finally lead to poor ice making effect or even the ice sheets cannot be stacked smoothly. Therefore, in this application, a heat insulation layer 21 is provided on the telescopic mold side frame 2, and the heat insulation layer 21 is made of a heat insulation material, and specifically, polyurethane foam can be used for filling. By this means, it can play a role in preventing ice from being formed after the atomized water flow is sprayed outside the telescopic mold side frame 2.

[0048] To ensure that the gap between the mold side frame 2 and the mold bottom plate 1 does not cause water leakage, the mold opening precision of the mold bottom plate 1 and the mold side frame 2 is a positive and negative tolerance of 0.01 - 0.02 mm. Under the efficient heat conduction efficiency of the present utility model, the mold can reach a relatively low temperature during operation. When the fine water flow of the atomizing nozzle 3 is sprayed, an ice surface will be quickly formed at the bottom layer of the sheet-like space, playing a sealing role; and the smaller tolerance can further ensure the sealing performance of the ice-making mold. Under the condition of maintaining a certain mold opening precision and based on the efficient heat conduction efficiency, water cannot penetrate into the mold gap with a positive and negative tolerance of 0.01 - 0.02 mm, achieving the effect of ensuring the ice-making stability.

[0049] Working principle:

[0050] Furthermore, when ice-making is carried out on the mold bottom plate 1, due to the restraining effect of the mold side frame 2, a regular sheet-like ice layer, simply referred to as ice sheet, will be formed on the refrigeration component on the surface of the mold bottom plate 1. At this time, the mold side frame 2 is driven by the threaded rod 22 to descend. Then, the lead screw drive gear drives the threaded lead screw to rotate, and the ice block push rod 52 pushes the ice sheet towards the receiving groove 61. After the ice sheet enters the receiving groove 61, the atomizing nozzle 3 sprays water mist towards the ice sheet in the receiving groove 61, causing a water film to form on the surface of the ice sheet. After multiple ice-making - pushing actions, a sufficient number of ice sheets are pushed into the receiving groove 61 to wait for the extrusion component to assemble the ice sheets.

[0051] After a sufficient number of ice sheets are pushed into the assembly box, the extrusion plate presses downward. At this time, the ice sheets with residual water film will be bonded together due to the characteristics of ice, that is, in a low-temperature room and under mutual extrusion, the ice sheets coated with water will be bonded together, and then the ice sheets are assembled into ice blocks with sufficient thickness, ensuring the ice-making effect of the ice-making equipment.

[0052] Compared with the traditional ice-making machine in which the subsequent ice layers in the ice block are made by the cold quantity conducted from the bottom layer of ice, the present utility model equally divides the ice block into a certain number of ice sheets, and each ice sheet is made by the direct heat conduction of the evaporator 11. Therefore, it can effectively shorten the time required for refrigeration and improve the ice-making efficiency. At the same time, the ice sheets can also be assembled into ice blocks with appropriate thickness in the assembly part. During use, the melting time can be effectively extended, that is, the refrigeration effect of the refrigeration equipment can be ensured. Embodiment 2

[0053] The difference from Embodiment 1 is:

[0054] See Figure 1-2, the ice-making component uses the evaporator 11. After the ice sheet is formed on the mold bottom plate 1, the evaporator 11 switches to the heating mode, causing the ice between the ice sheet and the mold bottom plate 1 to melt and form a water film. When the ice sheet is pushed into the receiving groove 61 by the first horizontal pushing component 51, the water film on the surface of the ice sheet will continue to exist for a short time, and then it can ensure that the ice sheets are pressed together to condense into one body after being extruded by the extrusion component.

[0055] This embodiment also has other setting forms on the extrusion component: Refer to Figure 5-6 , the cross-section of the receiving groove 61 is the same as the cross-section of the inner cavity of the side frame 2 of the evaporator 11 mold; a support plate 62 is arranged at the bottom of the receiving groove 61 through a vertical lifting component; the extrusion component includes a pushing top plate 63 and a second horizontal pushing component; the pushing top plate 63 is arranged above the side of the receiving groove 61, and the bottom surface of the pushing top plate 63 is flush with the top surface of the mold bottom plate 1; the second horizontal pushing component is used to horizontally push the pushing top plate 63 towards the receiving groove 61, and a downward protruding pressing part is arranged at the bottom of the pushing top plate 63, and the pressing part is used to apply a vertical pressing force to the ice sheet. Specifically, the vertical lifting component and the second horizontal pushing component can adopt a screw lifting device or a hydraulic lifting device.

[0056] The beneficial effect of this setting form is that after the ice sheets enter the assembly part, they will be squeezed and spliced layer by layer. Compared with the technical solution of concentrating the ice sheets and then extruding them in Embodiment 1, this embodiment can ensure that each layer of ice sheets is effectively extruded to ensure that the finally spliced ice cubes have a tighter structure, thereby improving the ice-making effect of the ice maker.

[0057] At the same time, this embodiment also has other setting forms on the vertical lifting component. Refer to Figure 1-2 , the vertical lifting component includes a lifting rod 621 and a threaded rod 22. Among them, the lifting rod 621 is arranged on both sides of the support plate 62 and passes through the vertical sliding grooves 611 opened on both sides of the assembly box; the threaded rod 22 is vertically placed and sleeved in the threaded groove opened at the free end of the lifting rod 621.

[0058] This setting method drives the threaded rod 22 to rotate through the motor, and then drives the support plate 62 to rise; at the same time, since the lifting rod 621 is limited by the vertical sliding groove 611, it can ensure that the support plate 62 can rise along a straight track, avoiding the situation that the support plate 62 is skewed and stressed during rising, which further causes uneven ice cube assembly.

[0059] At the same time, to ensure that the ice sheet can stably receive the downward pressing force, refer to Figure 6The pressing part is two raised strips 631 provided at the bottom of the push top plate 63, and the side of the raised strip 631 close to the receiving groove 61 has an arc transition. Furthermore, when the push top plate 63 is pushed up, the raised block can effectively reduce the contact area between the push top plate 63 and the ice flakes, thereby increasing the pressure of the ice flakes and increasing the adhesion of the ice flakes; and the arc transition can effectively guide the raised strips 631 to the upper surface of the ice flakes, instead of the raised strips 631 squeezing the side wall of the ice flakes as the second horizontal push-out assembly is pushed out, thereby avoiding the ice flakes from breaking as much as possible.

[0060] To ensure that the ice cubes can be pushed out stably after assembly, the side wall of the push top plate 63 facing the support plate 62 is set to be a straight plane, so that when the ice cubes are pushed out from the side by the push top plate 63, the pressure area of ​​the ice cubes can be effectively increased, thereby improving the stability of the ice cubes being pushed out.

[0061] Furthermore, in order to ensure that the atomized water flow can stably adhere to the mold surface, the mold bottom plate 1 and the mold side frame 2 of the utility model are both made of hydrophilic materials, specifically metal materials such as aluminum or silver.

[0062] In order to ensure that the ice flakes will not stick to the pushing portion and the pushing top plate 63 when being pushed out, the first horizontal pushing component 51 and the pushing top plate 63 are both made of hydrophobic materials, and specifically copper can be used as the manufacturing material.

[0063] Working principle:

[0064] The atomizing nozzle 3 is operated to spray a uniform atomized water flow onto the mold bottom plate 1. The refrigeration component on the mold bottom plate 1 cools the atomized water flow on the mold bottom plate 1 to form a regular ice sheet. The mold side frame 2 is lowered until the top surface of the mold side frame 2 is flush with the top surface of the mold bottom plate 1.

[0065] The evaporator 11 is switched to the heating mode, so that the contact surface between the ice flakes and the ice flake mold melts to form a layer of water film. The first horizontal pushing component 51 pushes the ice flakes toward the receiving groove 61, causing it to fall into the receiving groove 61. The pushing top plate 63 is pushed out by the second horizontal pushing component, and the downward extrusion force generated by the sliding of the pushing top plate 63 on the upper surface of the ice flakes is used to apply a vertical extrusion force to the ice flakes contained in the receiving groove 61. The above steps are repeated so that the several ice flakes contained in the receiving groove 61 are squeezed and bonded, and as the ice flakes are stacked, ice cubes of a predetermined thickness are formed.
