[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] In an exemplary technology, whether the water dispenser is a water dispenser placed on top of a water bucket and uses gravity to discharge water, or a water dispenser placed below a water bucket and uses a water pump to pump water, a cold tank is required to store a certain amount of low-temperature cold water to ensure sufficient cold water output. The cold tank of the water dispenser is not only used to store cold water, but also to replenish water to the hot tank. However, if the cold tank and the hot tank are directly connected and the cold water in the cold tank is directly input into the hot tank, not only will the hot water in the hot tank flow into the cold tank, resulting in a loss of cold capacity in the cold tank, but it will also increase the load on the hot tank and increase the heating time of the hot tank.

[0045] In order to solve the above problems, the utility model proposes a diverter plate, which is applied to the cold tank of the water dispenser. The diverter plate is used to partition and isolate the cold tank, so as to solve the technical problem that the hot water from the hot tank flows into the cold tank, resulting in heat loss and increasing the load on the hot tank. For the convenience of understanding, in each embodiment of the utility model, the water dispenser in the following is described as a vertical water dispenser with the cold tank on top and the hot tank below the cold tank, but it is not limited to this.

[0046] Reference Figures 1 to 6 In one embodiment, the diverter plate provided by the present invention includes a diverter tray 100 and an overflow ring 200 .

[0047] The diverter tray 100 has a first side 111 and a second side 112 opposite to each other. The diverter tray 100 is used to be installed in the cold tank 600 to separate a cold water zone 510 formed on the second side 112 thereof in the cold tank 600. The overflow ring 200 is provided on the first side 111 of the diverter tray 100 to separate a normal temperature zone 520 and a mixing zone 530 formed on the first side 111 of the diverter tray 100 in the cold tank 600. The normal temperature zone 520 is formed in the overflow ring 200, and the mixing zone 530 is formed outside the overflow ring 200. The diverter tray 100 is provided with a drain port 120 at a position corresponding to the mixing zone 530. The drain port 120 is used to connect the mixing zone 530 and the cold water zone 510.

[0048] In this embodiment, the normal temperature zone 520 is used to store normal temperature water, and the mixing zone 530 is connected to the cold water zone 510 through the drain port 120, and is used to transfer normal temperature water to the cold water zone 510 and prevent the cold water in the cold water zone 510 from mixing with the normal temperature water in the normal temperature zone 520.

[0049] The first side 111 and the second side 112 of the diverter tray 100 are arranged opposite to each other. Optionally, the upper side of the diverter tray is used as the first side 111 of the diverter tray, and the lower side of the diverter tray is used as the second side 112 of the diverter tray 100. The diverter tray is arranged in the cold tank 600 to define a cold water area 510 and a non-cold water area 510 in the cold tank 600. The inner circumferential wall of the cold tank 600 and the second side 112 of the diverter disk enclose the cold water zone 510 shown; the inner circumferential wall of the cold tank 600 and the first side 111 of the diverter disk enclose the non-cold water zone 510 shown, and the non-cold water zone 510 is further divided into a normal temperature zone 520 and a mixed zone 530 by the overflow ring 200 provided on the first side 111 of the diverter disk. Since the overflow ring 200 is annular, the normal temperature zone 520 and the mixed zone 530 are separated by the overflow ring 200, and the normal temperature zone 520 is determined to be formed in the overflow ring 200, and the mixed zone 530 is formed outside the overflow ring 200. In addition, in other replaceable embodiments, it is optionally replaced to determine that the mixed zone 530 is formed in the overflow ring 200, and the normal temperature zone 520 is formed outside the overflow ring 200; this is not limited here.

[0050] In one embodiment, the cold tank 600 is provided with a normal temperature water inlet 611 or other water inlets, and the normal temperature water inlet 611 is optionally set to an open port provided at the top of the cold tank 600, or a water inlet provided on the top cover of the cold tank 600. In order to reflect the advantage of reducing the energy consumption of the whole machine in the present application, the water intake through the normal temperature water inlet 611 is mainly described. In actual implementation, the normal temperature water inlet 611 may not be limited to being used for intake of normal temperature water. Normal temperature water or other water enters the normal temperature zone 520 of the cold tank 600 through the normal temperature water inlet 611. After the water entering the normal temperature zone 520 is sufficient to overflow from the overflow ring 200 to the mixing zone 530, the water entering the mixing zone 530 enters the cold water zone 510 through the downspout 120 provided in the mixing zone 530.

[0051] It should be noted that normal temperature water is a relative concept. It usually refers to water at normal room temperature. Its temperature does not have a fixed value because it varies with the environment, season and geographical location. In most indoor environments, the temperature of normal temperature water is roughly between 20℃ and 25℃. But please note that this is only a rough range and may actually vary due to various factors. In addition, normal temperature water used in water dispensers may also be understood as tap water or bottled water that has not been heated or cooled. The temperature of this water varies depending on the season and geographical location. In general, the specific temperature of normal temperature water is not a fixed value, but a relative concept that needs to be determined based on specific environments and conditions.

[0052] The overflow ring 200 is provided to prevent the water entering the cold tank 600 from directly entering the cold water zone 510, so as to slow down the flow speed of the normal temperature water and the speed at which the normal temperature water enters the cold water zone 510, and further reduce the energy consumption of the whole machine, and prevent the normal temperature water from flowing too fast and excessively mixing with the cold water in the cold water zone 510 at the bottom of the cold tank 600, thereby increasing the single cold water output; in this way, the problem of temperature leakage can also be prevented, resulting in too low a warm water outlet temperature, and even increasing the heat load and heating time of the hot tank, affecting the heating efficiency and user experience. In addition, the normal temperature water overflowing from the normal temperature zone 520 to the mixing zone 530 through the overflow ring 200 enters the cold water zone 510 through the water outlet 120. The setting of the water outlet 120 can also be used to increase the flow cross-sectional area of ​​the normal temperature water entering the cold water zone 510, so as to avoid the problem of insufficient water replenishment in the cold water zone 510 and the inability to replenish water in time that may occur when the normal temperature zone 520 and the cold water zone 510 are completely separated. The water outlet 120 can be used for any type of diverter plate and cold tank 600 that need to increase the cold water output of the cold tank 600. The setting of the water outlet 120 can also be used to guide the normal temperature water and other drinking water entering the cold tank 600 through the normal temperature water inlet 611 to flow downward to the cold water zone 510 according to the specified flow path. By controlling the water replenishment in the cold water zone 510, the working process of the water dispenser is further controlled to improve the reliability of temperature control and avoid heat loss.

[0053] In one embodiment, the water dispenser further includes a hot tank 700 .

[0054] Because the cold tank 600 and the hot tank of the existing water dispenser are directly connected, the cold tank 600 directly provides cold water to the hot tank 700. When the cold tank 600 and the hot tank 700 are used together, part of the high-temperature steam generated by the hot tank 700 will directly enter the cold tank 600, causing a temperature leakage problem. This will not only cause a loss of cold capacity in the cold tank 600, but also increase the load on the hot tank and increase the heating time of the hot tank.

[0055] To further avoid the problem of temperature leakage, the diverter tray is also provided with a warm water drain pipe 400, and the diverter tray 100 is provided with a warm water drain port 140 connected to the warm water drain pipe 400 at a position corresponding to the warm water drain pipe 400; the warm water drain pipe 400 is used to connect with the hot tank 700.

[0056] The hot tank 700 is replenished with warm water through the warm water downpipe 400 arranged on the diversion plate, instead of directly transmitting the cold water in the cold water zone 510 of the cold tank 600 into the hot tank 700, so as to shorten the heating time of the hot tank and avoid the problem of energy waste. In this way, it is also possible to avoid the water in the hot tank 700 from flowing into the cold water zone of the cold tank 600 to cause heat loss and avoid the loss of cold capacity of the cold tank 600.

[0057] Optionally, the hot tank 700 is provided with a water inlet pipe, which is in communication with the warm water drain pipe 400. The water inlet pipe and the warm water drain pipe 400 are optionally arranged on the same pipeline or on different independent pipe sections. When they are arranged on different pipe sections, the water inlet pipe and the warm water drain pipe 400 are optionally provided with a connecting portion 410 to achieve combined connection; the specific arrangement can be based on actual conditions and is not limited here.

[0058] Optionally, in one embodiment, the diverter tray is disposed in the cold tank body 610, and the overflow ring 200 is spaced apart from the inner circumferential wall of the cold tank 600, so as to enclose a mixing zone 530 between the outer circumferential wall of the overflow ring 200, the inner circumferential wall of the cold tank 600 and the diverter tray 100. Optionally, in order to ensure that the warm water and the cold water are fully mixed before flowing out from the cold water outlet 612, the drain port 120 is limited to be opened at the far end of the diameter of the connecting line between the warm water drain port 140 (or the fixed pipe 300 described below) and the center of the diverter tray 100, that is, the drain port 120 is limited to be arranged at the periphery of the diverter tray 100 or close to the periphery of the diverter tray 100; in this way, the structure can be simplified, the diverter tray can be processed, assembled and installed conveniently, and the processing cost can be reduced. The drain port 120 may specifically be, but is not limited to, a regular or irregular slot; alternatively, the diameter width of the outer peripheral wall of the diverter tray 100 is smaller than the diameter width of the inner peripheral wall of the cold tank 600, and the drain port 120 is a gap formed between the outer peripheral wall of the diverter tray 100 and the inner peripheral wall of the cold tank 600.

[0059] Furthermore, in one embodiment, the water outlet 120 is disposed adjacent to the overflow ring 200 to ensure that the water overflowing from the normal temperature zone 520 through the overflow ring 200 to the mixing zone 530 can enter the cold water zone 510 through the water outlet 120 to avoid excessive water accumulation in the mixing zone 530 .

[0060] Because the outer peripheral wall of the overflow ring 200, the inner peripheral wall of the cold tank 600 and the diversion tray 100 enclose a mixing zone 530, the water outlet 120 is limited to be arranged adjacent to the overflow ring 200, and the diversion tray 100 of the diversion tray is used to isolate the normal temperature zone 520 and the cold water zone 510 in the cold tank 600. When normal temperature water is supplied to the hot tank 700 through the normal temperature zone 520 instead of directly supplying cold water to the hot tank through the cold water zone 510, the water outlet 120 is limited to be arranged adjacent to the overflow ring 200, so that the normal temperature water overflowing to the mixing zone 530 can enter the cold water zone 510 in time through the water outlet 120, so as to improve the cold water outlet efficiency. In addition, by limiting the water outlet 120 to be arranged adjacent to the overflow ring 200, the space occupied by the mixing zone 530 can be reduced, and the space occupied by the diversion tray and the cold tank 600 can be further reduced, so as to facilitate transfer and use.

[0061] Optionally, since the mixing zone 530 is enclosed between the outer wall of the overflow ring 200, the inner wall of the cold tank 600 and the diverter tray 100, the size of the diverter tray 100 can be determined specifically according to the size of the inner wall of the cold tank 600, so that the outer wall of the diverter tray 100 arranged in the cold tank 600 is arranged close to the inner wall of the cold tank 600, and the normal temperature water overflowing from the normal temperature zone 520 through the overflow ring 200 to the mixing zone 530 enters the cold water zone 510 through the drain 120; or, a gap is formed between the outer wall of the diverter tray 100 and the inner wall of the cold tank 600, and the normal temperature water overflowing from the normal temperature zone 520 through the overflow ring 200 to the mixing zone 530 enters the cold water zone 510 through the gap between the outer wall of the diverter tray 100 and the inner wall of the cold tank 600 and the drain 120.

[0062] In one embodiment, there is at least one water outlet 120 . When there are multiple water outlets 120 , the multiple water outlets 120 are arranged at intervals along the circumference of the diversion tray 100 .

[0063] The shapes and sizes of the multiple drains 120 may be the same or different. When there are multiple drains 120, the spacing distances between adjacent different drains 120 may be the same or different. The specific settings may be based on actual conditions, and the shape, size and position of the drain 120 are not limited herein.

[0064] As a further embodiment, optionally, when different numbers of multiple water outlets 120 are provided, the total area of ​​the multiple water outlets 120 is limited to be no greater than a set area value, so as to ensure that the normal temperature water in the mixing zone 530 can enter the cold water zone 510 through the water outlet 120, while controlling the speed at which the normal temperature water enters the cold water zone 510, so as to avoid the normal temperature water flowing too fast and excessively mixing with the cold water in the cold water zone 510 at the bottom of the cold tank, thereby increasing the single cold water output and causing energy waste.

[0065] As a further embodiment, a thermostat is provided in the cold tank 600, and the thermostat includes a temperature control body and a temperature sensing tube, one end of the temperature sensing tube is connected to the temperature control body, and the temperature sensing tube includes a temperature sensing tube body and a temperature sensing head, and the temperature sensing head is arranged on the temperature sensing tube body, and the temperature sensing head is used to sense the temperature, and the temperature sensing tube body has a plurality of curved sections, and the plurality of curved sections are close to each other and form a detection part distributed in a planar manner. By setting the temperature sensing tube body to have a plurality of curved sections, the temperature sensing contact surface is increased and the temperature sensing error is reduced. The curved section is annular, and the plurality of curved sections are sequentially connected along the central axis thereof to form a cylindrical spiral arrangement; or, the plurality of curved sections are sequentially connected along the central axis thereof to form a plane spiral arrangement. In order to further improve the temperature sensing accuracy and reduce the temperature sensing error, the temperature sensing head is limited to be close to or at least partially arranged along the center line of the detection part, so that the temperature sensing area of ​​the temperature sensing tube is more concentrated. In order to enable the thermostat to sense the water temperature change in the cold tank 600 more quickly and to make up for the disadvantage of low temperature sensing accuracy, the position of the temperature sensing head can be specifically limited to correspond to the position of the water outlet 120. The water outlet 120 is arranged directly above the temperature sensing head of the thermostat in the cold tank 600. Through the water outlet 120, the water entering the cold tank 600 can flow downward along the designated flow path to the designated position of the cold water zone 510, so that the thermostat can timely detect the temperature change of the water entering the cold water zone 510 through the water outlet 120.

[0066] In one embodiment, the diverter tray is further provided with a fixing column for installing the diverter tray 100 in the cold tank 600. By providing the fixing column, the diverter tray is stably installed in the cold tank 600.

[0067] In order to make full use of the internal space of the cold tank 600 and reduce the setting of water outlets and other connection ports, in one embodiment, the cold tank 600 is provided with a cold water outlet 612, the fixing column is a fixing tube 300, the fixing tube 300 has a first end and a second end arranged opposite to each other, the first end of the fixing tube 300 is connected to the second side 112 of the diversion tray 100, and the second end of the fixing tube 300 is provided with a plug 310 for plugging and connecting with the cold water outlet 612. The second end of the fixing tube 300 can also be connected to the cold water outlet 612 by a snap connection, a threaded connection, etc., which is not limited here. The second end of the fixing tube 300 is connected and fixed to the cold water outlet 612 of the cold tank 600 by the plug 310. Specifically, a cold water outlet connected to the cold water area 510 can be set between the connection position of the fixed pipe 300 and the cold water outlet 612, on the fixed pipe 300 or on the cold water outlet 612 to achieve cold water discharge, so as to complete the installation of the diverter plate without affecting the water discharge of the cold water area 510 of the cold tank 600.

[0068] As an example, the fixed pipe 300 is used as a connection structure to firmly install the diverter plate in the hot tank 700, and is also used as a water outlet pipe of the cold water area 510 to discharge cold water. The fixed pipe 300 is provided with a cold water outlet 320, which is used to connect the cold water outlet 612 and the cold water area 510, and the cold water outlet 320 is at least arranged near the second end of the fixed pipe 300.

[0069] Optionally, a cold water outlet 320 is provided on the second end of the fixed pipe 300 or on the peripheral side wall near the second end, and the cold water outlet 320 is used to connect the cold water outlet and the cold water zone 510. The fixed pipe 300 may be, but is not limited to, a hollow pipe with a completely through middle portion, and the cold water outlet 320 is connected to the fixed pipe 300 to form a cold water outlet pipeline in the middle portion of the fixed pipe 300; or, a water outlet channel is provided at the second end of the fixed pipe 300, and the water outlet channel extends from the second end of the fixed pipe 300 toward the middle portion thereof to form a cold water outlet 612 at the second end of the fixed pipe 300, so that the cold water in the cold water zone 510 is discharged through the cold water outlet 612 provided at the second end.

[0070] In one embodiment, at least one ice-blocking prevention hole 130 is disposed on the diversion tray 100 , and the ice-blocking prevention hole 130 is used to connect the normal temperature zone 520 and the cold water zone 510 .

[0071] Optionally, the anti-ice-blocking hole 130 is circular, square, or any other shape suitable for actual use. There is at least one anti-ice-blocking hole 130, and at least one anti-ice-blocking hole 130 is provided at any position of the diverter tray 100. When a plurality of anti-ice-blocking holes 130 are provided, the plurality of anti-ice-blocking holes 130 can be arranged in rows, columns, or in any form at any position of the diverter tray 100, which is not limited here.

[0072] In one embodiment, the diameter of each ice-blocking prevention hole 130 is between 1 mm and 4 mm. The size of the ice-blocking prevention hole 130 can be adjusted according to production and use requirements and is not limited here.

[0073] In one embodiment, the water dispenser further includes an evaporator. The evaporator cover of the water dispenser is arranged outside the cold tank 600, and the position of the evaporator corresponds to the position of the cold water zone 510, so as to cool down the cold water zone 510. When the compressor of the water dispenser works for a long time, the evaporator continuously transfers cold energy to the cold tank 600 to achieve cooling. The temperature of the wall of the cold tank 600 is lower than the temperature of the middle part of the cold tank 600. When the water temperature near the wall of the cold tank 600 drops below 0 degrees Celsius without stopping for a long time, ice will appear. Because the distance between the diverter plate and the cold tank 600 is small, the mixing zone 530 of the diverter plate is prone to ice blockage, that is, the water in the cold tank 600 cannot directly enter the cold water zone 510 through the drain port 120.

[0074] In order to solve the problem of being unable to discharge cold water due to ice blockage, in one embodiment, the ice blocking hole 130 is limited to be set in the middle of the diverter tray 100. When ice blockage occurs in the mixing area 530 of the diverter tray, water can still be replenished to the cold water area 510 through at least one ice blocking hole 130 set in the middle of the diverter tray 100, ensuring the normal operation of the water system.

[0075] In addition, in some optional embodiments, in order to ensure the normal operation of the water system of the system and avoid excessive mixing of the normal temperature water with the cold water in the cold water area 510 at the bottom of the cold tank during daily operation, the hole area of ​​the ice blocking hole 130 is limited to be no larger than the area of ​​the water outlet 120. When multiple water outlets 120 are provided, the hole area of ​​all ice blocking holes 130 can be further limited to be no larger than the area of ​​any water outlet 120; this can be set according to actual conditions and is not limited here.

[0076] The specific working mechanism of the water dispenser of the present invention for achieving refrigeration and heating can be referred to the relevant description of the prior art, which will not be described in detail here.

[0077] Reference Figure 5 The utility model also provides a cold tank 600 for a water dispenser, which includes a cold tank body 610 and a diverter plate. The cold tank body 610 is provided with a normal temperature water inlet 611, a cold water outlet 612 and a hot tank connection port 613. The diverter plate is the diverter plate for a water dispenser as shown in the above embodiment, and is arranged in the cold tank body 610.

[0078] Since the cold tank 600 for the water dispenser adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments.

[0079] Furthermore, the overflow ring 200 is spaced apart from the inner wall of the cold tank 600 to enclose a mixing zone 530 between the outer wall of the overflow ring 200 , the inner wall of the cold tank 600 and the diversion tray 100 ; the normal temperature water inlet 611 is connected to the normal temperature zone 520 .

[0080] Optionally, the diverter plate is connected and fixed in the cold tank body 610; or, in order to facilitate assembly production and reduce processing costs, the diverter plate and the cold tank body 610 are set independently of each other, and the diverter plate is detachably installed in the cold tank body 610; the specific settings can be based on actual conditions and are not limited here.

[0081] Furthermore, the diverter plate includes a fixed pipe 300 and a warm water drain pipe 400. The diverter plate is installed in the cold tank 600 through the fixed pipe 300. The cold water area 510 is connected to the cold water outlet 612 through the cold water outlet 320 provided on the fixed pipe 300; the warm water drain pipe 400 is used to connect to the hot tank through the hot tank connection port 613. By arranging the diverter plate in the water dispenser to separate the normal temperature area 520 and the cold water area 510 in the cold tank 600, the hot tank is replenished with warm water through the warm water drain pipe 400 provided on the diverter plate, and the cold water in the cold water area 510 of the cold tank 600 is not directly transmitted to the hot tank, so as to shorten the heating time of the hot tank and avoid the problem of energy waste; in this way, it is also possible to avoid the water in the hot tank from entering the cold water area of ​​the cold tank 600 to cause heat loss, and avoid the loss of cold capacity of the cold tank 600.

[0082] The utility model also provides a water dispenser, referring to Figure 6 The water dispenser includes a cold tank 600 and a hot tank 700, wherein the cold tank 600 is the cold tank 600 for the water dispenser as shown in the above embodiment; the hot tank is connected to the warm water drain pipe 400.

A section of the water inlet pipe 710 located in the hot tank 700 is provided with an exhaust hole 711. The exhaust hole 711 is provided to release the pressure to reduce the pressure difference between the hot tank 700 and the cold tank, and solve the problem of high-temperature water flowing back to the cold tank due to the increase in air pressure inside the tank body after the high-temperature steam is generated. The water inlet pipe 710 and the warm water drain pipe 400 can be optionally provided on the same pipeline or on different independent pipe sections. When provided in different pipe sections, the water inlet pipe 710 and the warm water drain pipe 400 can be optionally provided with a connecting portion 410 to achieve a combined connection; the specific setting can be based on actual conditions and is not limited here.
