Description

Technical Field

[0001] The utility model relates to the technical field of water diversion machines, in particular to a double-tank warm water machine. Background Art

[0002] Direct drinking water machine is a kind of household appliance that purifies water and makes it drinkable directly. Through multi-stage purification, tap water in the home can be directly drunk. There are two types of water heaters in the current market: step-by-step water heaters and warm water heaters. Among them, the step-by-step water heater is an energy-saving water heater that heats the water layer by layer from the bottom layer until the water is boiled.

[0003] Step-type water machines can only provide boiled water and direct drinking water, but not warm water. When you are thirsty, you usually mix boiled water with direct drinking water to adjust the temperature. If it is hot, add more cold water, and if it is cold, add some boiled water. It is difficult to control the temperature of the mixed water. On the one hand, it wastes the time of collecting water, and on the other hand, long-term reciprocating operation will accelerate the service life of the machine's water valve and direct drinking water valve.

[0004] The structural principle of the existing warm water machine is to adopt a heat exchanger method. When taking water, the boiled water is cooled by the heat exchanger and becomes warm water. The warm water is directly passed into the water outlet for drinking. When the warm water temperature is not suitable, professionals are required to open the shell and adjust it. Especially for the change of seasons between summer and winter, the difference in heat exchange effect caused by the cold water temperature in the heat exchange equipment will also lead to a difference in the outlet temperature of the warm boiled water.

[0026] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0027] Embodiment 1:

[0028] This embodiment provides a double-tank warm water machine, such as Figure 1-Figure 3 As shown, it includes a heat exchanger 5, a boiling water tank 3, a warm water tank 4 and a main control board 104, wherein the boiling water tank 3 is used to heat boiling water and store boiling water, and the warm water tank is used to store warm boiled water. An insulation layer may be provided on the outside of the boiling water tank and the warm water tank so that the boiling water tank and the warm water tank have a certain insulation effect.

[0029] The cold water is connected to the first end of the cold source pipe in the heat exchanger 5 through the first water inlet pipe 62, and the second end of the cold source pipe in the heat exchanger 5 is connected to the water inlet end of the hot water tank 3 through the second water inlet pipe 63. After the cold water is heated by heat exchange in the heat exchanger 5, it enters the hot water tank 3 for heating and is heated into boiling water in the hot water tank 3. The temperature of the cold water after passing through the heat exchanger 5 increases, and the thermal energy is effectively utilized, so that the temperature difference of the water that needs to be heated in the hot water tank 3 is reduced, saving energy consumption and cost.

[0030] The water outlet of the boiled water tank 3 is connected to the second end of the heat source pipe in the heat exchanger 5 through the first water outlet pipe 64, and the first end of the heat source pipe in the heat exchanger 5 is connected to the water inlet of the warm water tank 4 through the second water outlet pipe 65. The heat exchanger 5 is an existing heat exchange device, and the boiled water in the heat source pipe of the heat exchanger 5 and the cold water in the cold source pipe flow relative to each other, and heat exchange occurs, so that the temperature of the cold water flowing out of the second end is increased, and the temperature of the boiled water flowing out of the first end is reduced to become warm water, and the warm water flows to the warm water tank 4 for storage. The water outlet of the warm water tank 4 is connected to the warm water faucet 81 through the warm water outlet pipe 66, and the user takes warm water through the warm water faucet 81.

When multiple taps are taking water at the same time, the water output of each tap is guaranteed to be sufficient and continuously supplied, which solves the problem of traditional pure heat exchange warm water machines. Because the water output relies on the raw water pressure to push the warm water out, when multiple taps are taking water at the same time, there will be a situation where the taps or water points far away in the pipeline will have less water or interruption due to the partial pressure.

A third control valve 73 is provided on the warm water outlet pipe 66, and the third control valve 73 is used to regulate the water outlet of the warm water faucet 81, and the purpose of taking warm water can also be achieved by switching the third control valve 73. The first control valve 71, the second control valve 72, the third control valve 73 and the first water pump 91 are all connected to the main control board 104, and multiple control valves and pumps can be regulated by the main control board 104. There can be multiple warm water faucets 81, and each warm water faucet 81 is correspondingly provided with a third control valve 73.

[0035] As a preferred embodiment, the double-tank warm water machine in this embodiment also includes a water purification membrane assembly 1 and a water storage tank 2. One end of the water purification membrane assembly 1 is connected to an external water source and the other end is connected to the water storage tank 2 through a third water inlet pipe 61. The water purification membrane assembly 1 is used to filter the external water source and pass the treated water to the water storage tank 2 for storage. The water storage tank 2 supplies cold water to stabilize the flow. The other end of the water storage tank 2 is connected to a first water inlet pipe 62, which is used to pass cold water to the heat exchanger 5 as a cold source for heat exchange with boiled water. A second water pump 92 is provided on the third water inlet pipe 61 between the water purification membrane assembly 1 and the water storage tank 2. The second water pump 92 is used to provide power for the water flow so that the cold water can flow smoothly into the water storage tank 2 after being purified by the water purification membrane assembly 1.

[0036] The water storage tank 2 is connected to the cold water faucet 83 through the cold water outlet pipe 68, and a fifth control valve 75 is provided on the cold water outlet pipe 68, and the fifth control valve 75 is connected to the main control board 104. The user can take cold water through the cold water faucet 83, and adjust the water output and switch of the cold water through the fifth control valve 75.

[0037] The water purification membrane assembly 1 can be a reverse osmosis membrane assembly, which has a good water purification effect. The water purification membrane assembly 1 can be connected to tap water to filter the tap water so that the filtered water can meet the standard of direct drinking.

The liquid level sensor is used to detect the upper water level in the boiling water tank 3 and the warm water tank 4, so as to control the water level in the boiling water tank 3 and the warm water tank 4 through the main control board 104, and avoid the phenomenon of heating due to insufficient water level. When the water level in the warm water tank 4 is low, the water in the boiling water tank can be transported to the warm water tank 4 by opening the second control valve 72 and the first water pump 91. When the water level in the boiling water tank is insufficient, the cold water in the water storage tank can be allowed to enter the boiling water tank after heat exchange by opening the first control valve 71. It should be noted that the water storage tank can also be directly connected to the boiling water tank through a pipeline to directly provide cold water to the boiling water tank, and the cold water becomes boiling water after being heated in the boiling water tank. A water pump can be provided on the second water inlet pipe 63 to provide power for the transportation of cold water.

[0040] As a preferred embodiment, an LED ultraviolet sterilizer is provided at the water outlet of the warm water tank 4, and the LED ultraviolet sterilizer is connected to the main control board 104.

[0041] As a preferred embodiment, the double-tank warm water machine in this embodiment further includes an outer shell 101 and a frame 102. Figure 1 and Figure 2As shown, the outer shell 101 is connected to the outside of the frame 102, and the heat exchanger 5, the boiled water tank 3 and the warm water tank 4 are all installed on the frame 102 in the outer shell 101. A water receiving platform 103 that is concave backward is provided on the front side of the outer shell 101, and the warm water faucet 81 is installed on the upper side of the water receiving platform 103, and the boiled water faucet 82 and the cold water faucet 83 are arranged side by side with the warm water faucet 81 on the upper side of the water receiving platform 103. The warm water tank 4 is installed on the upper part of the frame 102, and the installation height of the warm water tank 4 is higher than the installation height of the warm water faucet 81, so that the warm boiled water can flow out under the action of gravity when the warm water faucet 81 is discharged. In addition, the installation height of the warm water tank 4 can also be lower than the installation height of the warm water faucet 81, and a water outlet pump is installed on the warm water outlet pipe 66 to realize the water outlet of the warm water faucet 81. The boiled water tank 3 is installed at the lower part of the frame 102 and is located below the warm water tank 4. The heat exchanger 5 is installed in the middle of the frame 102 to reduce the length of the first water inlet pipe 62, the second water inlet pipe 63, the first water outlet pipe 64 and the second water outlet pipe 65. The main control board 104 is installed on the outer shell 101 on the upper side of the water receiving platform 103 for easy regulation. The water storage tank 2 is arranged on the left or right side of the boiled water tank 3, and the water purification membrane assembly 1 is arranged on the front side of the water storage tank 2. A support plate 105 is arranged in the middle of the frame 102, and multiple water pumps can be installed on the support plate 105. Rollers 106 are connected to the four corners of the bottom end of the frame 102 to facilitate movement.

[0042] The above-mentioned first control valve 71 to the fifth control valve 75 are solenoid valves. The water inlet, exchange and heating processes of warm water and boiled water are automatically controlled by the main control board automatic system and the imported program; when the temperature sensor and liquid level sensor of each water tank detect the corresponding value, it will be transmitted to the main control board. The main control board automatically starts each valve to perform program actions such as water inlet, water exchange and water outlet according to the requirements set on demand; at the same time, the heating system will also automatically start heating and other actions according to the feedback value of the temperature sensor to meet the warm water requirements of the set temperature.

[0043] The working process of the double-tank warm water machine provided in this embodiment is as follows:

[0044] The raw water is purified by the water purification membrane assembly 1 and then enters the water storage tank 2 as backup cold water; the cold water enters the boiled water tank 3 through the outer pipe of the heat exchanger 5; the boiled water heated to the set temperature in the boiled water tank 3 enters the inner sleeve of the heat exchanger 5, and exchanges heat with the cold water entering the outer sleeve of the heat exchanger, so that the boiled water is cooled down and the cold water is heated up; the cooled warm boiled water enters the warm water tank 4 through the first water pump 91; the warm boiled water entering the warm water tank 4 can be taken by the demander on demand through the third control valve, and the temperature of the warm boiled water can be freely set according to demand. When the temperature is low, the heating system in the warm water tank will automatically start the heating function through the temperature sensor signal and the main control board instruction to heat up until the required set temperature. Because the water temperature in the warm water is after the heat exchange of the boiled water and has a certain temperature, it can quickly reach the set temperature through the heating system in the warm water tank. At the same time, there is also the warm water input supplemented by the heat exchange in the boiled water tank. The water storage tank ensures timely supply of purified water, and the boiling water tank ensures that a certain amount of boiling water enters the warm water tank for standby after heat exchange with purified cold water. This forms an uninterrupted cycle, thereby ensuring the formation of a large amount of warm boiled water and boiling water, thereby meeting the needs of large water usage.

[0045] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
