Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ice-making evaporators, in particular to a novel ice-making evaporator. BACKGROUND

[0002] In the field of household appliances, the ice-making function is no longer limited to traditional electrical appliances such as ice machines and refrigerators. Some multifunctional water dispensing devices such as water dispensers, tea bar machines, and purified drinking machines also gradually come with ice-making functions, making the functions more diverse and the user experience better. The evaporator is the core component of the ice-making function of the electrical appliance, mainly including an ice-making shell and a heat-conducting piece. The heat-conducting piece circulates refrigerant, and the refrigerant absorbs the heat of the water flowing in the ice-making shell, so that the water flowing in the ice-making shell gradually freezes into ice. The traditional ice-making shell has only one ice-making cavity, and the ice in the ice-making cavity freezes into a whole ice block. The whole ice block is cut into small ice blocks according to needs after being taken out, which is very inconvenient to use. Therefore, the existing ice-making shell is mostly provided with a grid that separates the shell into multiple ice cells, and multiple small ice blocks can be directly made through the multiple ice cells. However, the ice-making shell with multiple ice cells has a problem. When the ice blocks are frozen in the ice cells, the ice blocks in the left and right adjacent ice cells are easily frozen together, which is not convenient for the independent and rapid falling of each ice block from the ice cell. Moreover, when the ice blocks in one ice cell fall, the ice blocks in the adjacent ice cells that are frozen together will also be taken out and fall into the ice storage box at the same time. The ice blocks that are frozen together are broken and separated by colliding with the ice storage box, generating a large amount of ice shavings, which is difficult to maintain the shape of the ice blocks and the ice shavings are also difficult to clean. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a novel ice-making evaporator to improve or solve the technical problem that the ice blocks in adjacent ice cells are easily frozen together in the existing evaporator.

[0004] The technical scheme adopted by the present application is as follows:

[0005] A novel ice-making evaporator, comprising a shell, a grid piece, and a heat-conducting piece arranged at the rear side of the shell. The front side of the shell is provided with an ice-making tank. The grid piece comprises a transverse grid and a longitudinal grid that are cross-connected. The transverse grid and the longitudinal grid separate the ice-making tank into multiple ice cells. The longitudinal grid has an ice-separating protrusion that protrudes outward from the ice-making tank in the longitudinal direction. The novel ice-making evaporator further comprises a heat-insulating piece that covers at least part of the ice-separating protrusion.

[0006] The novel ice-making evaporator provided by the present application further comprises the following additional technical features:

[0007] The heat-insulating piece is provided with a cavity that is adapted to the ice-separating protrusion. The ice-separating protrusion is inserted into the cavity.

[0008] The top surface of the ice separation protrusion has a length L1 in the longitudinal direction, and the top wall of the cavity has a length L2 in the longitudinal direction, where L2≥L1, so that the top surface of the ice separation protrusion can be entirely covered by the top wall of the cavity.

[0009] The bottom surface of the ice separation protrusion has a length L3 in the longitudinal direction, and the bottom wall of the cavity has a length L4 in the longitudinal direction, where L3>L4, so that the end of the ice separation protrusion close to the shell has a de-icing area exposed to the outside of the cavity.

[0010] The opening end of the cavity for inserting the ice separation protrusion is recessed in the direction away from the shell.

[0011] The heat insulation member is a flexible structure, and the ice separation protrusion is interference-fitted in the cavity.

[0012] The top of the ice separation protrusion is provided with an upwardly protruding limiting protrusion, and the cavity is provided with a limiting groove matched with the limiting protrusion.

[0013] The bottom surface of the ice separation protrusion gradually inclines downward from the end close to the shell to the end away from the shell.

[0014] The shell is provided with an air outlet hole on the bottom surface of the ice making tank, and the longitudinal grid is provided with a gap connecting the ice cells on both sides.

[0015] The transverse grid divides the ice making tank into two layers of ice cells, and divides the gap into an upper gap and a lower gap. In the upper layer of ice cells, adjacent two ice cells are connected through the upper gap. In the lower layer of ice cells, adjacent two ice cells are connected through the lower gap. The air outlet hole includes an upper air outlet hole corresponding to the upper layer of ice cells and a lower air outlet hole corresponding to the lower layer of ice cells.

[0016] Thanks to the above technical solutions, the application achieves at least the following technical effects:

[0017] 1. The novel ice making evaporator provided by the application divides the ice making tank into multiple ice cells by the transverse grid and the longitudinal grid. Compared with the prior art, the longitudinal grid has an ice separation protrusion protruding outward from the ice making tank in the longitudinal direction, and a heat insulation member is arranged on the ice separation protrusion. The ice separation protrusion and the heat insulation member can effectively prevent the water in the ice cells on both sides of the longitudinal grid from converging during ice making, thereby preventing the ice blocks in the ice cells on both sides of the longitudinal grid from freezing and adhering, allowing the ice blocks to be independently kept in the ice cells in a granular form, allowing the ice blocks to be independently and quickly removed from the ice cells when ice is taken, reducing the output of ice residues, and long-term maintaining the shape of the ice blocks, thereby improving the use experience of the equipment using the novel ice making evaporator.

[0018] 2. As a preferred embodiment, the heat insulation member is provided with a cavity matched with the ice separation protrusion, and the ice separation protrusion is inserted into the cavity. On the one hand, the heat insulation member is easy to assemble, and is not easy to fall off after assembly under the support of the ice separation protrusion. On the other hand, the heat insulation member can wrap the outer edge of the ice separation protrusion, effectively prevent the ice water in the adjacent ice compartments from adhering, and prevent the ice blocks in the adjacent ice compartments from freezing together.

[0019] 3. As a preferred embodiment, the length of the top surface of the ice separation protrusion along the longitudinal direction is L1, and the length of the top wall of the cavity along the longitudinal direction is L2, wherein L2≥L1, so that the top surface of the ice separation protrusion can be entirely covered by the top wall of the cavity. Under the blockage of the heat insulation member, the water in the adjacent ice compartments is difficult to flow over the top of the ice separation protrusion and freeze together, thereby avoiding the adhesion of the upper part of the ice blocks.

[0020] 4. As a preferred embodiment, the length of the bottom surface of the ice separation protrusion along the longitudinal direction is L3, and the length of the bottom wall of the cavity along the longitudinal direction is L4, wherein L3>L4, so that the ice separation protrusion has a de-icing area exposed to the outside of the cavity near the shell. This effectively increases the contact area of the ice blocks with the longitudinal grid, so that the ice blocks can quickly fall out of the ice compartments when the shell is heated for de-icing. In addition, by providing the de-icing area, the heat insulation member can also avoid the sliding process of the ice blocks from the ice compartments, preventing the edges of the heat insulation member from blocking the sliding of the ice blocks.

[0021] 5. As a preferred embodiment, the heat insulation member is a flexible structure, and the ice separation protrusion is inserted into the cavity with interference. Through this design, on the one hand, the firmness of the heat insulation member around the ice separation protrusion can be improved, so that the heat insulation member is not easy to fall off, and the ice separation effect is improved. On the other hand, the ice separation protrusion can also be closely fitted to the inner wall of the cavity, effectively preventing ice water from entering the cavity and freezing into ice.

[0022] 6. As a preferred embodiment, the top of the ice separation protrusion is provided with a limiting protrusion protruding upward, and the cavity is provided with a limiting groove matched with the limiting protrusion. Through the cooperation of the limiting protrusion and the limiting groove, the heat insulation member is reliably limited, reducing the risk of the heat insulation member falling off the ice separation protrusion.

[0023] 7. As a preferred embodiment, the bottom surface of the ice separation protrusion gradually inclines downward from one end close to the shell to the other end away from the shell. On the one hand, the bottom of the ice compartments on both sides can be reliably separated, preventing the bottom of the ice blocks on both sides from freezing and adhering. On the other hand, the ice separation protrusion can also guide the sliding of the ice blocks from the ice compartments. In addition, the lower end of the ice separation protrusion forms a sharp structure, which can hook and limit the heat insulation member, effectively preventing the bottom of the heat insulation member from separating from the ice separation protrusion.

[0024] 8. As a preferred embodiment, by setting the exhaust hole, the air staying inside the ice tray can be squeezed out of the exhaust hole when the water flow flows through the ice tray, so as to avoid the air entering the ice block as much as possible, increase the transparency of the ice block, and further improve the aesthetic appearance.

[0040] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail with reference to the accompanying drawings.

[0041] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the present application can be practiced without the specific details and other implementations can be employed. Thus, the scope of the present application is not intended to be limited to the particular examples described.

[0042] In addition, in the description of the present application, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "transverse", "longitudinal", and the like, indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0043] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "fixing" and the like should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection, or communication; can be directly connected, or indirectly connected through an intermediate medium; can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0044] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In the present application, the illustrative description of the above terms is not necessarily directed to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0045] In the embodiments of the present application, a new ice-making evaporator is provided. In order to facilitate the description and understanding, the following content provided by the present application is described on the basis of the structure of the product. Of course, those skilled in the art can understand that the above structure is only a specific example and illustrative description, and cannot constitute a specific limitation on the technical solutions provided by the present application.

[0046] As Figures 1 to 8As shown, the new ice-making evaporator provided by the present application comprises a shell 1, a grating 2, and a heat-conducting member 3 arranged at the rear side of the shell 1. The front side of the shell 1 is provided with an ice-making tank. The grating 2 comprises a transverse grating 21 and a longitudinal grating 22 which are cross-connected. The transverse grating 21 and the longitudinal grating 22 divide the ice-making tank into a plurality of ice cells 4. The longitudinal grating 22 has an ice-separating protrusion 221 which protrudes outward from the ice-making tank in the longitudinal direction. The new ice-making evaporator further comprises a heat-insulating member 5 which covers at least a partial region of the ice-separating protrusion 221.

[0047] Specifically, a heat-conducting substance which circulates and flows can be arranged in the heat-conducting member 3. Water flows downward through the ice-making tank from the top of the shell 1. The heat-conducting substance absorbs the heat of the water flow passing through the interior of the shell 1 through the shell 1, so that the water flow is gradually frozen into ice to form ice blocks. The transverse grating 21 and the longitudinal grating 22 divide the ice-making tank into a plurality of ice cells 4. An ice block which is generally consistent with the internal contour of each ice cell 4 can be frozen in each ice cell 4. In the prior art, the longitudinal grating is entirely hidden in the ice-making tank, which causes the ice blocks on both sides of the longitudinal grating to be easily frozen and adhered together across the longitudinal grating. Therefore, compared with the prior art, the new ice-making evaporator provided by the present application can effectively prevent the water in the ice cells 4 on both sides of the longitudinal grating 22 from converging during the ice-making process, and further prevent the ice blocks in the ice cells 4 on both sides of the longitudinal grating 22 from being frozen and adhered together, by virtue of the ice-separating protrusion 221 and the heat-insulating member 5. As a result, the ice blocks can be independently kept in each ice cell 4 in a granular form. When ice is taken out, the ice blocks can be independently and quickly detached from the ice cells 4, which reduces the output of ice residues and also effectively maintains the shape of the ice blocks, thereby improving the use experience of the equipment which uses the new ice-making evaporator.

[0048] The present application does not limit the connection mode of the heat-insulating member 5 and the ice-separating protrusion 221. For example, the heat-insulating member 5 can be pasted on the ice-separating protrusion 221. As another example, the heat-insulating member 5 can be fixed on the ice-separating protrusion 221 by screws. As a preferred embodiment of the present application, as shown in Figure 1 and Figures 3 to 6 The heat-insulating member 5 is provided with a cavity which is adapted to the ice-separating protrusion 221. The ice-separating protrusion 221 is inserted into the cavity. Through this arrangement, on the one hand, the heat-insulating member 5 is facilitated to be assembled and is not easy to fall off under the support of the ice-separating protrusion 221 after assembly. On the other hand, the heat-insulating member 5 can wrap the outer edge of the ice-separating protrusion 221, which effectively prevents the ice water in adjacent ice cells 4 from converging, thereby preventing the ice blocks in adjacent ice cells 4 from being frozen together.

[0049] As a preferred embodiment, as shown in Figure 6 andFigure 7 As shown, the top surface of the ice-separation protrusion 221 has a length dimension L1 in the longitudinal direction, and the top wall of the cavity has a length dimension L2 in the longitudinal direction, where L2≥L1, so that the top surface of the ice-separation protrusion 221 is entirely covered by the top wall of the cavity. As can be appreciated by those skilled in the art, the top of the ice-separation protrusion 221 forms a dangerous position for the ice blocks in the adjacent ice cell 4 to stick together, especially when the ice blocks have been substantially shaped in the ice cell 4 at the end of the freezing process, at which time the ice blocks gradually fill the ice cell 4, causing the water flow in the ice cell 4 to easily cross the top of the ice-separation protrusion 221 and then freeze the upper part of the ice blocks in the adjacent ice cell 4 together after freezing. Therefore, by making L2≥L1, the top surface of the ice-separation protrusion 221 is entirely covered by the top wall of the cavity, and the water in the adjacent ice cell 4 is prevented from crossing the top of the ice-separation protrusion 221 and freezing together under the blocking of the thermal insulation member 5, thereby avoiding the upper part of the ice blocks from sticking together.

[0050] Further, as shown in Figs. 2 and 3, the bottom surface of the ice-separation protrusion 221 has a length dimension L3 in the longitudinal direction, and the bottom wall of the cavity has a length dimension L4 in the longitudinal direction, where L3>L4, so that the ice-separation protrusion 221 has a de-icing area 2211 exposed to the outside of the cavity near the shell 1. Figure 6 Figure 8 As can be appreciated by those skilled in the art, the de-icing method of the evaporator is generally to heat the shell by a heating device to separate the ice blocks from the shell, the transverse grid and the longitudinal grid, and then make the ice blocks fall from the ice cell, and therefore, by providing the de-icing area 2211, the contact area of the ice blocks with the longitudinal grid 22 is effectively increased, so that the ice blocks can quickly fall from the ice cell 4 when de-icing by heating the shell 1, and further, by providing the de-icing area 2211, the thermal insulation member 5 can be avoided during the falling process of the ice blocks from the ice cell 4, preventing the edge of the thermal insulation member 5 from blocking the falling of the ice blocks.

[0051] As a preferred embodiment, the opening end of the cavity for inserting the ice-separation protrusion 221 is recessed in a direction away from the shell 1. As shown in Figs. 2 and 3, the recessed opening end of the cavity makes the edge line of the thermal insulation member 5 near the ice cell 4 (the dashed line in Fig. 3) an arc line concave inward, and by this arrangement, the area of the de-icing area 2211 is effectively increased, the contact area of the ice-separation protrusion 221 with the ice blocks is increased, and then the de-icing by heating is facilitated. Figure 3 Figure 6 Figure 6

[0052] ​​​​As a preferred embodiment, the heat insulation member 5 is a flexible structure, and the ice partition protrusion 221 is interference-fitted in the cavity. Those skilled in the art can understand that, through this design, on the one hand, the firmness of the heat insulation member 5 fitted on the ice partition protrusion 221 can be improved, so that the heat insulation member 5 is not easy to fall off, the ice partition effect is improved, and on the other hand, the ice partition protrusion 221 can be tightly attached to the inner wall of the cavity, effectively preventing ice water from entering the cavity and freezing into ice. As a preferred solution, the heat insulation member 5 can be made of silica gel, which is flexible, has strong heat insulation performance, is environmentally friendly, and will not pollute the ice.

[0053] Preferably, as shown in Figure 3 、 Figure 6 and Figure 7 , the top of the ice partition protrusion 221 is provided with an upward protruding limiting protrusion 222, and the cavity is provided with a limiting groove 51 matched with the limiting protrusion 222. Through the cooperation of the limiting protrusion 222 and the limiting groove 51, the heat insulation member 5 is reliably limited, reducing the risk of the heat insulation member 5 falling off from the ice partition protrusion 221.

[0054] Preferably, as shown in Figure 6 and Figure 8 , the bottom surface of the ice partition protrusion 221 gradually inclines downward from one end close to the shell 1 to the other end away from the shell 1. On the one hand, the ice partition protrusion 22 protrudes downward relative to the shell by a distance, which can reliably separate the bottoms of the ice cells 4 on both sides and prevent the bottoms of the ice blocks on both sides from freezing and adhering, and on the other hand, it can guide the ice blocks falling from the ice cells 4. In addition, the lower end of the ice partition protrusion 221 forms a sharp structure, which can hook and limit the heat insulation member 5, effectively preventing the bottom of the heat insulation member 5 from separating from the ice partition protrusion 221.

[0055] As a preferred embodiment of the present application, as shown in Figure 1 and Figure 2 , the shell 1 is provided with an exhaust hole 11 on the bottom surface of the ice making groove, and the longitudinal grid 22 is provided with a gap 223 communicating a plurality of ice cells. Those skilled in the art can understand that, during the freezing and forming of the ice blocks in the ice cells 4, if the ice blocks contain a lot of air, the ice blocks will be white due to the formation of a plurality of air bubbles inside, which will reduce the transparency of the ice blocks and affect the user experience. Therefore, it is necessary to reduce the air as much as possible during the freezing and forming of the ice blocks. The present solution provides the exhaust hole 11 and the gap 223, which can squeeze out the air remaining in the ice cells 4 through the exhaust hole 11 when the water flows through the ice cells 4, thereby avoiding the air entering the ice blocks as much as possible, increasing the transparency of the ice blocks, and improving the aesthetic appearance.

[0056] Further, as shown in Figure 1 and Figure 2As shown, the transverse grid 21 divides the ice making tank into two layers of ice cells 4, and divides the gap 223 into an upper gap and a lower gap. In the upper layer of ice cells 4, adjacent two ice cells 4 are communicated through the upper gap. In the lower layer of ice cells 4, adjacent two ice cells 4 are communicated through the lower gap. The exhaust hole 11 includes an upper exhaust hole 111 corresponding to the upper layer of ice cells 4 and a lower exhaust hole 112 corresponding to the lower layer of ice cells 4. Since each ice cell 4 needs to exhaust air outward, on the basis of the communication of the upper layer of ice cells 4 and the lower layer of ice cells 4, the number of exhaust holes 11 can be reduced, and it is not necessary to set an exhaust hole 11 at the position corresponding to each ice cell 4. For example, one exhaust hole 11 can be set at each corner of the shell 1, wherein the exhaust hole 11 at the upper end corner of the shell 1 is the upper exhaust hole 111, and the exhaust hole 11 at the lower end corner of the shell 1 is the lower exhaust hole 112.

[0059] The above only describes the embodiments of the present application and is not used to limit the present application. The present application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the scope of claims of the present application.
