Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, and specifically to a hot water tank assembly and its water dispenser. Background Technology

[0002] Step-type water heaters are generally used in commercial water dispensers. They are energy-saving water heating devices that heat water layer by layer from the bottom until it boils. This improves upon the separation of hot and cold water while ensuring a healthy, single-boil water temperature, reducing the likelihood of "mixed" or "unmixed" water. Electrical control ensures only one boil, completely avoiding repeated heating. After each liter of water is heated and boiled, another liter is added from the bottom until the tank is full. Step-type water heaters can continuously dispense boiling water, avoiding the waiting time of traditional water heaters where the entire tank of water must be boiled before dispensing.

[0003] For example, Chinese utility model patent CN209436962U discloses a step-type bar counter water purifier, which includes a water tank and a control system installed inside the casing. The water tank has a water outlet pipe in the middle of the front side and a water inlet pipe at the bottom of the rear side. The casing includes a base plate, a front panel, two side panels, a back panel, and a cover plate connected by rivets. The water tank is installed on the base plate. The water outlet pipe has a water outlet valve exposed at the front of the front panel. A water receiving platform is installed below the water outlet valve. A water purifier and an electromagnetic water inlet valve are installed on the water inlet pipe. The water purifier is hung on the rear side of the back panel. An electric heating tube is installed in the lower rear part of the water tank. The electromagnetic water inlet valve and the electric heating tube are both electrically connected to the control system. However, the outlet of the existing design is located in the middle of the water tank. Users can only take hot water from the outlet when the actual water level is higher than the water level at the outlet. When there is still a lot of hot water below the outlet in the water tank, cold water needs to be added to push the water level up before water can be taken. Users need to wait for a certain period of time, which makes it impossible to quickly take hot water.

[0004] Therefore, existing technologies still need to be improved and developed to address the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a hot water tank assembly and its water dispenser.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a hot water tank assembly, including a tank body, a heating element, a temperature sensor, and a control module. Specifically, the tank body can be a sealed container assembled from a tank body and a tank lid. The heating element can be a heating tube. Both the heating element and the temperature sensor are located inside the tank body. Preferably, the mounting ends of the heating element and the temperature sensor are fixed to the upper end of the tank body. Both the heating element and the temperature sensor are electrically connected to the control module.

[0008] The upper end of the tank is provided with a water inlet and a vent. The vent can be connected to a pressure relief valve to ensure the water pressure inside the tank. The bottom of the tank is provided with a water outlet. The water inlet is connected to a first electronic control switch, preferably a solenoid valve. The tank is equipped with a multi-stage water level monitoring mechanism. It should be noted that the multi-stage water level monitoring mechanism can be configured as a two-stage, three-stage, or other mechanism depending on the size of the tank. The multi-stage water level monitoring mechanism is electrically connected to the control module. The multi-stage water level monitoring mechanism can sense several water level signals at different heights inside the tank and transmit the water level signals to the control module. The control module controls the opening and closing of the first electronic control switch according to the signals. When boiling water, the control module controls the first electronic switch to open, allowing cold water to flow in from the inlet at the top of the tank. When the water level reaches the first monitoring level at the bottom of the multi-level water level monitoring mechanism, the control module controls the first electronic switch to close, and controls the heating element to heat the first layer of cold water. When the temperature sensor detects that the water temperature reaches 100 degrees Celsius, the temperature signal is transmitted to the control module, which then controls the heating element to stop heating. Then, the control module controls the first electronic switch to open again, and cold water continues to be supplied until the second monitoring level is reached. The first electronic switch then closes, and the heating element continues to operate. When the temperature sensor detects that the water temperature reaches 100 degrees Celsius, the heating element stops heating, and so on, ensuring that all water reaching the last monitoring level is heated. When taking water, hot water flows out from the bottom of the tank. The user can take water until the water level drops to the first monitoring level, during which time cold water is not supplied. Alternatively, if the user takes water intermittently, the control module will open the first electronic switch when the user stops taking water, continuing to supply cold water and heating the water level step by step. With the above structural design, the tank can achieve layered water intake and segmented heating, resulting in rapid heating. Moreover, the hot water flows out from the bottom of the tank, allowing users to quickly remove the hot water from the middle and lower parts of the tank.

[0009] According to the above scheme, a baffle plate is provided vertically inside the tank, and a water passage hole is provided at the bottom of the baffle plate. The baffle plate divides the tank into a heating chamber and a hot water outlet chamber. The heating chamber and the hot water outlet chamber are connected through the water passage hole. The upper part of the heating chamber is connected to the water inlet, and the bottom of the hot water outlet chamber is connected to the water outlet. The heating element is placed at the bottom of the heating chamber. With the above structural arrangement, the water in the heating chamber is heated layer by layer. The hot water at the bottom of the heating chamber flows into the hot water outlet chamber through the water passage hole. When the user takes water, they will first take the pre-heated hot water stored in the hot water outlet chamber, rather than the lukewarm water mixed with cold water in the heating chamber.

[0010] According to the above scheme, the multi-stage water level monitoring mechanism is installed inside the hot water outlet chamber. With this structural arrangement, when a user draws water, the water level in the hot water outlet chamber changes faster than the water level in the heating water chamber. By installing the multi-stage water level monitoring mechanism inside the hot water outlet chamber, it can monitor and respond to water level changes in a timely manner, allowing the control module to promptly control the first electronic control switch to open and replenish cold water.

[0011] According to the above scheme, the multi-level water level monitoring mechanism includes a water level sensor, and the water level sensor is equipped with multiple water level control switches. With this structural setup, when cold water is added and the water level rises to the corresponding water level control switch, the water body will trigger the water level control switch, transmitting the water level signal to the control module.

[0012] According to the above scheme, the water level sensor is equipped with a low water level control switch, a medium water level control switch, and a high water level control switch. This structural design allows for the layer-by-layer heating of water at low, medium, and high water levels, meeting the requirement for continuous and rapid water output.

[0013] According to the above scheme, the sensing end of the temperature sensor is placed at the bottom of the heating chamber. This structural arrangement allows for precise monitoring of the water at the bottom of the heating chamber and timely response to the control module, enabling the control module to control the heating element to heat or de-heat.

[0014] According to the above scheme, the water outlet is connected to a water pump via a pipe. With this structural arrangement, when the water level is low or medium, the water pump can accelerate the flow of hot water.

[0015] This utility model also provides a water dispenser, which includes a main housing, a water outlet, and the aforementioned hot water tank assembly. The main housing can be assembled from a main outer shell, an upper cover, a lower cover, and a rear cover. The water outlet has a hot water channel and is fixedly connected to the main housing. The hot water tank assembly is installed inside the main housing, and the hot water channel is connected to the water outlet of the water pump. With the above structural arrangement, hot water in the hot water chamber can flow out from the water outlet.

[0016] This utility model also includes a first cold water pipeline and a second cold water pipeline. The first cold water pipeline is connected to the inlet. The second cold water pipeline is equipped with a second electric control switch, which is a solenoid valve. The second electric control switch is electrically connected to the control module. The outlet has a cold water channel, and the second cold water pipeline is connected to the cold water channel. Specifically, when it is necessary to heat cold water, the control module opens the first electric control switch, and cold water flows into the inlet through the first cold water pipeline. When it is necessary to directly draw cold water, the control module opens the second electric control switch, and cold water flows into the cold water channel of the outlet through the second cold water pipeline.

[0017] According to the above scheme, a display control panel is fixedly installed on the main housing. The display control panel is electrically connected to the control module. Specifically, a front cover plate is fixedly installed on the front side of the main housing, and the display control panel is embedded in the front cover plate. With the above structural arrangement, the display control panel can display the water temperature in the tank and control the water output using the buttons on the display control panel.

[0018] The beneficial effects of this utility model are:

[0019] This invention enables water to enter in layers and be heated in sections within the tank, achieving rapid heating. Furthermore, hot water flows out from the bottom of the tank, allowing users to quickly remove hot water from the middle and lower parts of the tank. Attached Figure Description

[0024] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-3 As shown in the figure, the arrows indicate the direction of water flow. This utility model provides a hot water tank assembly, including a tank body 1, a heating element 2, a temperature sensor 3, and a control module (not shown in the figure). Specifically, the tank body 1 is a sealed container assembled from a tank body 101 and a tank cover 102. The upper end of the tank body 101 is open, and the tank cover 102 is placed on the upper end of the tank body 101. A sealing ring 108 is provided between the tank cover 102 and the tank body 101. The heating element 2 is a heating tube. Both the heating element 2 and the temperature sensor 3 are located inside the tank body 101. The mounting ends of the heating element 2 and the temperature sensor 3 are fixed to the tank cover 102. Both the heating element 2 and the temperature sensor 3 are electrically connected to the control module.

[0026] The tank cover 102 is provided with a water inlet 103 and a vent 104. The bottom of the tank body 101 is provided with a water outlet 105. The water inlet 103 is connected to a first electric control switch 8, which is a solenoid valve. The tank body 101 is provided with a multi-level water level monitoring mechanism. The multi-level water level monitoring mechanism is electrically connected to the control module. The multi-level water level monitoring mechanism can sense several water level signals at different heights inside the tank body 101 and transmit the water level signals to the control module. The control module controls the opening and closing of the first electric control switch 8 according to the signals. When boiling water, the control module controls the first electronic switch 8 to open, allowing cold water to flow in through the inlet 103 on the lid 102. When the water level reaches the first monitoring level at the bottom of the multi-level water level monitoring mechanism, the control module controls the first electronic switch 8 to close, controlling the heating element 2 to heat the first layer of cold water. When the temperature sensor 3 detects that the water temperature has reached 100 degrees Celsius, the temperature signal is transmitted to the control module, which then controls the heating element 2 to stop heating. Then, the control module controls the first electronic switch 8 to open again, allowing cold water to continue flowing in. Upon reaching the second-level monitoring water level, the first electronic control switch 8 is turned off, while the heating element 2 continues to operate. When the temperature sensor detects that the water temperature has reached 100 degrees Celsius, the heating element 2 stops heating, and so on, ensuring that all water reaching the final monitoring water level is fully heated. When taking water, hot water flows out from the bottom of the tank body 101. The user can continue taking water until the water level drops to the first-level monitoring water level, during which time cold water will not be replenished. Alternatively, if the user takes water intermittently, the control module will control the first electronic control switch 8 to turn on when the user stops taking water, continuing to replenish cold water and heating the water level step by step. Through the above structural design, the tank body 101 achieves layered water intake and segmented heating, resulting in rapid heating. Moreover, the hot water flowing out from the bottom of the tank body 1 allows the user to quickly retrieve hot water from the middle and lower parts of the tank body 1.

[0027] Furthermore, a baffle plate 4 is vertically arranged inside the tank body 101. The bottom of the baffle plate 4 has a water passage hole 401. The baffle plate 4 divides the tank body 101 into a heating chamber 106 and a hot water outlet chamber 107. The heating chamber 106 and the hot water outlet chamber 107 are connected through the water passage hole 401. The upper part of the heating chamber 106 is connected to the water inlet 103, and the bottom of the hot water outlet chamber 107 is connected to the water outlet 105. The heating element 2 is placed at the bottom of the heating chamber 106. With this structural arrangement, the water in the heating chamber 106 is heated layer by layer. The hot water at the bottom of the heating chamber 106 flows into the hot water outlet chamber 107 through the water passage hole 401. When the user takes water, they preferentially take the pre-heated hot water stored in the hot water outlet chamber 107, rather than the lukewarm water mixed with cold water in the heating chamber 106.

[0028] Furthermore, the multi-stage water level monitoring mechanism is installed within the hot water outlet chamber 107. With this structural arrangement, when a user draws water, the water level in the hot water outlet chamber 107 changes faster than the water level in the heating water chamber. Installing the multi-stage water level monitoring mechanism within the hot water outlet chamber 107 allows for timely monitoring and response to water level changes, enabling the control module to promptly open the first electronic control switch 8 to replenish cold water.

[0029] Furthermore, the multi-level water level monitoring mechanism includes a water level sensor 5, which is equipped with a low water level control switch 501, a medium water level control switch 502, and a high water level control switch 503. Through this structural arrangement, water at low, medium, and high water levels can be heated layer by layer, meeting the requirement for continuous and rapid water output.

[0030] Furthermore, the sensing end of the temperature sensor 3 is located at the bottom of the heating chamber 106. This structural arrangement allows for precise monitoring of the water at the bottom of the heating chamber 106 and timely response to the control module, enabling the control module to control the heating element 2 to heat or de-heat.

[0031] Furthermore, the outlet 105 is connected to a water pump 6 via a pipe. With this structural arrangement, when the water level is low or medium, the water pump 6 can accelerate the flow of hot water.

[0032] like Figure 3As shown, this utility model also provides a water dispenser, which includes a main housing, a water outlet 7, and the aforementioned hot water tank assembly. The main housing is assembled from a main outer shell 11, an upper cover 12, a lower cover 13, and a rear cover 14. The water outlet 7 has a hot water channel (not shown in the figure) inside, and the water outlet 7 is fixedly connected to the main housing. The hot water tank assembly is installed inside the main housing, and the hot water channel is connected to the water outlet of the water pump 6. With the above structural arrangement, hot water in the hot water chamber can flow out from the water outlet 7.

[0033] This utility model also includes a first cold water pipe and a second cold water pipe (not shown in the figure). The first cold water pipe is connected to the inlet 103. The second cold water pipe is equipped with a second electric control switch 9, which is a solenoid valve. The second electric control switch 9 is electrically connected to the control module. The outlet 7 is provided with a cold water channel (not shown in the figure). The second cold water pipe is connected to the cold water channel. Specifically, when it is necessary to heat cold water, the control module opens the first electric control switch 8, and cold water flows into the inlet 103 through the first cold water pipe. When it is necessary to directly connect cold water, the control module opens the second electric control switch 9, and cold water flows into the cold water channel of the outlet 7 through the second cold water pipe.

[0034] Furthermore, a display control panel 10 is fixedly installed on the main housing. The display control panel 10 is electrically connected to the control module. Specifically, a front cover plate 15 is fixedly installed on the front side of the main housing, and the display control panel 10 is embedded in the front cover plate 15. With the above structural arrangement, the display control panel 10 can display the water temperature of the tank body 101, and control the water output using the buttons on the display control panel 10.

[0035] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
