Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a water tank structure and a refrigerator. Background Technology

[0002] In the prior art, the filter element in the refrigerator water supply tank includes a hollow fiber membrane. The hollow fiber membrane has a high density and a large resistance to water flow, which can easily lead to unstable water supply and low water supply reliability. Utility Model Content

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a water tank structure that can improve the reliability of water supply.

[0004] The second objective of this invention is to provide a refrigerator that includes the water tank structure described in the above embodiments.

[0005] According to a first aspect embodiment of the present invention, the water tank structure includes: a tank body, a partition, and a filter element. The tank body has a filling port that can be opened and closed. The partition is disposed within the tank body, and the partition and the tank body define a first chamber and a second chamber, which are connected. The filling port is configured to allow external fluid to flow into the first chamber. The filter element is disposed on the partition, and the filter element is configured such that the head pressure of the fluid in the first chamber is greater than the filter element pressure, and the fluid is adapted to flow from the first chamber through the filter element into the second chamber.

[0006] According to the water tank structure of this utility model embodiment, by setting a partition in the tank body, and the partition and the tank body jointly defining a first chamber and a second chamber that are interconnected, the difference in water level between the first chamber and the second chamber allows the fluid in the first chamber to smoothly enter the filter element when the head pressure of the fluid in the first chamber is greater than the filter element pressure. After filtration, the fluid flows to the second chamber, thus facilitating the stable delivery of the filtered fluid inside the tank to the outside of the tank body through the water supply component. This improves the stability and reliability of the water supply of the water tank structure. At the same time, it eliminates the need for a dedicated water supply component to adapt to the water tank structure, reducing production costs.

[0007] In some embodiments, the housing includes a top wall and a bottom wall, the top wall and the bottom wall being disposed opposite to each other, one end of the partition being connected to the bottom wall, the other end of the partition extending toward the top wall, and the other end of the partition defining a communication opening with the top wall, the first chamber and the second chamber being connected through the communication opening.

[0008] This facilitates communication between the first and second chambers, ensuring they are at the same atmospheric pressure. This allows fluid in the first chamber to be forced into the second chamber, thereby improving the reliability of the water tank structure's water supply.

[0009] In some embodiments, the partition is disposed perpendicular to the bottom wall; or, the other end of the partition extends obliquely toward the second chamber along the bottom wall toward the top wall.

[0010] Therefore, the partition is set vertically to the bottom wall, which can improve the installation efficiency of the partition; the partition is set at an angle, which can increase the water head pressure of the fluid in the first chamber, making it easier for the fluid in the first chamber to pass through the filter element and enter the second chamber, thereby improving the water supply efficiency of the water tank structure.

[0011] In some embodiments, at least a portion of the bottom wall is recessed along the height direction of the housing to form a groove, which is located within the second cavity.

[0012] This effectively increases the height difference between the water levels in the first and second chambers, thereby improving the water supply efficiency of the water tank structure.

[0013] In some embodiments, the water tank structure further includes a water supply assembly disposed in the second chamber, the water supply assembly including a drive member and a water supply pipe, the drive member being located in the settling tank; one end of the water supply pipe being connected to the drive member, the other end of the water supply pipe extending out of the tank body, and the drive member being configured to output fluid from the second chamber to the outside of the tank body via the water supply pipe.

[0014] This facilitates the output of fluid filtered by the filter element in the second chamber to the outside of the tank, ensuring that the water tank structure can smoothly supply water to external structural components that require water supply.

[0015] In some embodiments, the end of the partition away from the filling port is formed with an installation port; and / or, the end of the partition away from the filling port and the housing define an installation port; the filter element is detachably disposed at the installation port.

[0016] This improves the efficiency of filter installation and removal, while also increasing the connection strength between the baffle and the tank, thus improving the water supply efficiency of the tank structure.

[0017] In some embodiments, the container includes: a container body and a cover plate, the container body having an opening; the cover plate is separably fitted to the container body, the cover plate being able to open and close the opening, and the filling port being disposed on the cover plate.

[0018] This facilitates the installation and replacement of partitions, filter elements, and water supply components inside the tank, improves the sealing performance of the tank, and enhances the ease of operation.

[0019] In some embodiments, the partition and the cover are spaced apart along the height direction of the housing, and the partition and the cover define the communication opening.

[0020] This facilitates the connection between the first and second chambers via a communication port, allowing fluid in the first chamber to be forced into the second chamber, thereby improving the reliability of the water tank structure's water supply.

[0021] In some embodiments, the volume of the first chamber is greater than or equal to the volume of the second chamber.

[0022] This maximizes the volume of fluid stored in the first chamber, increasing its water storage capacity and thus improving the stability and reliability of the water supply system.

[0023] The refrigerator according to a second aspect of the present invention includes the water tank structure described in any one of the above embodiments.

[0024] This improves the stability and reliability of the water supply inside the refrigerator, while eliminating the need for a dedicated water supply component to adapt to the water tank structure, thus reducing production costs.

[0025] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0028] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-10 The water tank structure 100 according to an embodiment of the present utility model includes: a tank body 10, a partition 20, and a filter element 30.

[0029] Specifically, such as Figures 5-7 As shown, the housing 10 has a filling port 13, which can be opened and closed; a partition 20 is disposed inside the housing 10, and the partition 20 and the housing 10 define a first chamber 40 and a second chamber 41, which are connected; the filling port 13 is configured so that external fluid flows into the first chamber 40 through the filling port 13; a filter element 30 is disposed on the partition 20, and the filter element 30 is configured so that the water head pressure of the fluid in the first chamber 40 is greater than the filter element pressure of the filter element 30, and the fluid is suitable to flow from the first chamber 40 through the filter element 30 into the second chamber 41.

[0030] The partition 20 abuts against the adjacent sidewalls of the box 10 on both sides along the thickness direction of the box 10. The partition 20 and the box 10 together define the area along the thickness direction of the box 10. Figure 5The first chamber 40 and the second chamber 41 are arranged in the first direction A, which is the width direction of the housing 10. The filling port 13 is located adjacent to the first chamber 40. External fluid can enter the first chamber 40 through the filling port 13. The first chamber 40 and the second chamber 41 are under the same atmospheric pressure. Due to the difference in water level in the first chamber 40 and the second chamber 41, the fluid in the first chamber 40 generates water head pressure. When the water head pressure of the fluid in the first chamber 40 is greater than the filter element pressure (i.e., resistance) of the filter element 30, the fluid in the first chamber 40 enters the filter element 30. After being filtered by the filter element 30, it flows to the second chamber 41 until the water levels in the first chamber 40 and the second chamber 41 are the same, and the fluid stops flowing.

[0031] According to the water tank structure 100 of this utility model embodiment, by providing a partition 20 inside the tank body 10, and the partition 20 and the tank body 10 jointly defining a first chamber 40 and a second chamber 41 that are interconnected, the difference in water level between the first chamber 40 and the second chamber 41 allows the fluid in the first chamber 40 to smoothly enter the filter element 30 when the head pressure of the fluid in the first chamber 40 is greater than the filter element pressure of the filter element 30. After filtration, the fluid flows to the second chamber 41, thereby facilitating the stable delivery of the filtered fluid inside the tank body 10 to the outside of the tank body 10 through the water supply assembly 50. This improves the stability and reliability of the water supply of the water tank structure 100. At the same time, it eliminates the need for a dedicated water supply assembly to adapt to the water tank structure 100, reducing production costs.

[0032] Optionally, the filter element 30 is composed of a hollow fiber membrane and activated carbon, and the fluid may be water.

[0033] According to some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the housing 10 includes a top wall 121 and a bottom wall 111, which are arranged opposite to each other. One end of the partition 20 is connected to the bottom wall 111, and the other end of the partition 20 extends toward the top wall 121. The other end of the partition 20 and the top wall 121 define a communication port 21, through which the first chamber 40 and the second chamber 41 are connected.

[0034] Top wall 121 and bottom wall 111 along Figure 5 The second direction B, i.e. the height direction of the box 10, is arranged opposite to it, and the top wall 121 is located above the bottom wall 111. The first direction A and the second direction B are perpendicular. The partition 20 is connected to the bottom wall 111 at one end along the second direction B, and the other end of the partition 20 away from the bottom wall 111 along the second direction B is spaced apart from the top wall 121. Together with the top wall 121, they define a communication opening 21, which is suitable for connecting the first chamber 40 and the second chamber 41.

[0035] Thus, the partition 20 and the top wall 121 together define the communication port 21, which facilitates the communication between the first chamber 40 and the second chamber 41, so that the first chamber 40 and the second chamber 41 are under the same atmospheric pressure. When external fluid enters the first chamber 40, and there is a difference in water level between the first chamber 40 and the second chamber 41, the fluid in the first chamber 40 can generate water head pressure. When the water head pressure of the fluid in the first chamber 40 is greater than the filter element pressure of the filter element 30, the fluid in the first chamber 40 is easily forced into the second chamber 41, thereby improving the reliability of water supply from the water tank structure 100.

[0036] According to some embodiments of this utility model, such as Figure 5 As shown, the partition 20 is perpendicular to the bottom wall 111. That is, one end of the partition 20 adjacent to the bottom wall 111 along the second direction B is perpendicularly connected to the bottom wall 111, and the other end of the partition 20 extends along the second direction B in a direction away from the bottom wall 111. Therefore, by perpendicularly aligning the partition 20 with the bottom wall 111, the installation of the partition 20 is facilitated, the installation efficiency of the partition 20 is improved, and the structural strength and stability of the partition 20 are also enhanced.

[0037] Optionally, the other end of the partition 20 extends obliquely towards the second chamber 41 along the direction from the bottom wall 111 to the top wall 121. That is, one end of the partition 20 adjacent to the bottom wall 111 along the second direction B is connected to the bottom wall 111, and the other end of the partition 20 extends obliquely towards the second chamber 41 along the direction from the bottom wall 111 to the top wall 121. Thus, the oblique extension of the partition 20 towards the second chamber 41 can increase the head pressure of the fluid in the first chamber 40, making it easier for the fluid in the first chamber 40 to pass through the filter element 30 and enter the second chamber 41, thereby improving the efficiency of fluid entering the second chamber 41 from the first chamber 40 and improving the water supply efficiency of the water tank structure 100.

[0038] According to some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, at least a portion of the bottom wall 111 is recessed along the height direction of the box 10, i.e., the second direction B, toward the direction away from the center of the box 10 to form a groove 14, which is located in the second chamber 41.

[0039] The bottom wall 111 located in the second chamber 41 is recessed along the second direction B toward the direction away from the top wall 121 to form a groove 14. At this time, the distance between the bottom wall 111 and the top wall 121 of the second chamber 41 along the second direction B is greater than the distance between the bottom wall 111 and the top wall 121 of the first chamber 40 along the second direction B.

[0040] Therefore, by forming a settling trough 14 in the second chamber 41, the bottom wall 111 of the first chamber 40 is higher than the bottom wall 111 of the second chamber 41, which can effectively increase the height difference of the water level in the first chamber 40 and the second chamber 41, thereby increasing the head pressure of the fluid in the first chamber 40, making it easier for the fluid in the first chamber 40 to pass through the filter element 30 and enter the second chamber 41, effectively improving the water supply efficiency of the water tank structure 100.

[0041] According to some embodiments of this utility model, such as Figures 4-9 As shown, the water tank structure 100 also includes a water supply assembly 50, which is located in the second chamber 41. The water supply assembly 50 includes a drive unit 51 and a water supply pipe 52. The drive unit 51 is located in the settling tank 14. One end of the water supply pipe 52 is connected to the drive unit 51, and the other end of the water supply pipe 52 extends out of the tank body 10. The drive unit 51 is configured to output the fluid in the second chamber 41 to the outside of the tank body 10 through the water supply pipe 52.

[0042] The drive unit 51 is located in the settling tank 14 of the second chamber 41. One end of the water supply pipe 52 is connected to the drive unit 51, and the other end extends out of the housing 10 and connects to the external structural components of the housing 10 that require water supply. In this application, combined with Figure 10 The other end of the water supply pipe 52 is connected to the ice maker 53, and the drive unit 51 can drive the filtered fluid in the second chamber 41 to be transported to the ice maker 53 through the water supply pipe 52.

[0043] Therefore, by placing the water supply component 50 inside the second chamber 41, the fluid filtered by the filter element 30 inside the second chamber 41 can be output to the outside of the tank 10, ensuring that the water tank structure 100 can smoothly supply water to the external structural components that need water supply.

[0044] Alternatively, the drive unit 51 may be a gear pump or a magnetic pump.

[0045] According to some embodiments of this utility model, the end of the partition 20 away from the filling port 13 has an installation port. The end of the partition 20 adjacent to the bottom wall 111 along the second direction B is connected to the bottom wall 111, and the installation port extends through at least a portion of the end of the partition 20 adjacent to the bottom wall 111 along the first direction A. The filter element 30 is detachably disposed at the installation port. Therefore, the installation and removal efficiency of the filter element 30 can be improved while simultaneously increasing the connection strength between the partition 20 and the housing 10.

[0046] Optionally, the end of the partition 20 away from the filling port 13 defines an installation port with the housing 10, and the filter element 30 is detachably disposed at the installation port. The end of the partition 20 adjacent to the bottom wall 111 is spaced apart from the bottom wall 111 along the second direction B, and the partition 20, the bottom wall 111, and the two side walls of the housing 10 along the thickness direction together define the installation port. Therefore, while improving the installation and removal efficiency of the filter element 30, the installation area of ​​the filter element 30 can be increased, thereby increasing the flow rate of fluid entering the second chamber 41 from the first chamber 40 per unit time and improving the water supply efficiency of the water tank structure 100.

[0047] According to some embodiments of this utility model, such as Figure 4 and Figure 7 As shown, the box body 10 includes: a box body 11 and a cover plate 12. The box body 11 has an opening. The cover plate 12 is separably fitted with the box body 11. The cover plate 12 can open and close the opening. The filling port 13 is provided on the cover plate 12.

[0048] The bottom wall 111 is the side wall of the box body 11 away from the cover plate 12 along the second direction B. The opening of the box body 11 is open along the second direction B in the direction away from the bottom wall 111. The cover plate 12 is opposite to the box body 11 along the second direction B and forms a separable fit. The shape and size of the cover plate 12 are adapted to the box body 11. The filling port 13 penetrates at least a portion of the cover plate 12 adjacent to the first chamber 40 along the second direction B.

[0049] Thus, through the separable engagement of the cover plate 12 and the tank body 11, when the cover plate 12 is separated from the tank body 11, the opening of the tank body 11 is opened, which facilitates the installation and replacement of the partition 20, filter element 30 and water supply component 50 inside the tank body 11. When the cover plate 12 is engaged with the tank body 11, the sealing performance inside the tank body 10 can be improved. At the same time, by setting the filling port 13 on the cover plate 12, it is convenient to continuously replenish fluid to the first chamber 40 of the tank body 10, thereby improving the ease of operation.

[0050] According to some embodiments of this utility model, such as Figure 5 As shown, the partition 20 and the cover plate 12 are spaced apart along the height direction of the box 10, i.e., the second direction B, and the partition 20 and the cover plate 12 define the communication port 21.

[0051] The partition 20 is connected to the bottom wall 111 on the box body at one end away from the cover plate 12 along the second direction B. The other end of the partition 20 is spaced apart from the cover plate 12 along the second direction B. The partition 20 and the cover plate 12 together define a communication port 21, which is suitable for connecting the first chamber 40 and the second chamber 41.

[0052] Therefore, by having the partition 20 and the cover plate 12 spaced apart along the height direction of the tank 10, the first chamber 40 and the second chamber 41 are connected through the communication port 21, so that the first chamber 40 and the second chamber 41 are under the same atmospheric pressure. When external fluid enters the first chamber 40, and there is a difference in water level between the first chamber 40 and the second chamber 41, the fluid in the first chamber 40 can generate head pressure. When the head pressure of the fluid in the first chamber 40 is greater than the filter element pressure of the filter element 30, the fluid in the first chamber 40 is easily forced into the second chamber 41, thereby improving the reliability of water supply from the water tank structure 100.

[0053] According to some embodiments of this utility model, such as Figure 5 As shown, the volume of the first chamber 40 is greater than or equal to the volume of the second chamber 41.

[0054] Within the limited space of the tank 10, the volume of the first chamber 40 for storing fluid can be maximized, thereby increasing the water storage capacity of the first chamber 40 and improving the stability and reliability of the water supply from the water tank structure 100.

[0055] The refrigerator 1 according to the second aspect of the present invention includes a water tank structure 100 of any of the above embodiments.

[0056] In this application, combined with Figures 1-3 The refrigerator 1 has a storage compartment inside, and multiple partitions 20 can be installed in the storage compartment. The partitions 20 can divide the storage compartment into multiple chambers such as a refrigerator compartment and a freezer compartment. The body 10 of the water tank structure 100 is installed in the refrigerator compartment. The body 10 can supply water to the ice maker 53 through the water supply pipe 52 to provide the water required for the ice maker 53 to make ice. The ice maker 53 is installed in the freezer compartment. The ice maker 53 can make ice from the water tank. The body 10 can be placed on the bottom surface of the refrigerator compartment near the freezer compartment, and the ice maker 53 can be placed on the top surface of the freezer compartment near the refrigerator compartment to facilitate the arrangement of the water supply pipe 52. This application does not limit the type of ice maker 53, as long as the ice maker 53 can receive water from the water tank structure 100 and freeze the water at a low temperature.

[0057] By employing a water tank structure 100 with an internal partition 20, the partition 20 and the cabinet 10 together define a first chamber 40 and a second chamber 41 that are interconnected. Utilizing the difference in water level between the first chamber 40 and the second chamber 41, when the head pressure of the fluid in the first chamber 40 is greater than the filter element pressure of the filter element 30, the fluid in the first chamber 40 can smoothly enter the filter element 30, and after filtration, flow to the second chamber 41. This facilitates the stable delivery of the filtered fluid inside the cabinet 10 to the outside of the cabinet 10 through the water supply assembly 50, improving the stability and reliability of the water supply inside the refrigerator 1. At the same time, it eliminates the need for a dedicated water supply assembly to adapt to the water tank structure 100, reducing production costs.
