Examples
With reference to fig. 1 and fig. 2, the embodiment provides a heat storage type water dispenser with two exhaust channels, which includes a water inlet end 1, a water outlet end 2 and a heat storage tank 3, where the water inlet end 1 at least has a water inlet flow channel communicated with the heat storage tank 3. Specifically, in the present embodiment, the water inlet end 1 has a cold water inlet channel 11 and a hot water inlet channel 12, wherein the cold water inlet channel 11 is connected to the water outlet end 2, and the cold water inlet channel 11 is provided with a first electromagnetic valve 111 for controlling the opening and closing thereof. The hot water inlet channel 12 is used to connect with the heat storage tank 3, and a second electromagnetic valve 121 is disposed on the channel for controlling the on/off of the hot water inlet channel. When the first electromagnetic valve 111 is opened, water flows from the cold water inlet channel 11 to the water outlet end 2 to supply cold water to the user side; when the second electromagnetic valve 121 is opened, water flows into the heat storage tank 3 from the hot water inlet channel 12, and hot water in the heat storage tank 3 flows to the water outlet end 2 from the water outlet channel 21 to supply hot water to the user side.
The heat storage tank 3 is configured to communicate with the pressure relief passage through the control valve 4, that is, the heat storage tank 3 communicates with the atmosphere through the pressure relief passage when the control valve 4 is opened. For example, the control valve 4 is a relief valve that opens when the pressure in the heat storage tank 3 reaches a certain value, and allows the hot vapor in the heat storage tank 3 to be discharged from the relief passage. Alternatively, the control valve 4 is a check valve that allows only gas in the heat storage tank 3 to be discharged in one direction. The present invention is not limited to these examples, and is not particularly limited.
In this embodiment, the pressure relief channel is divided into two branches, namely a first pressure relief channel 5 and a second pressure relief channel 6, and both pressure relief channels are exhaust channels. The first pressure relief channel 5 is communicated with the atmosphere, and the second pressure relief channel 6 is communicated with the water outlet end 2. The first pressure release passage 5 is provided with a first pressure release valve 51, the second pressure release passage 6 is provided with a second pressure release valve 61, and the second pressure release passage 6 is disposed on the upstream side of the first pressure release valve 51 (i.e., near the end of the heat storage tank 3). When the pressure value in the first pressure relief channel 5 is greater than the pressure threshold value of the first pressure relief valve 51, the first pressure relief valve 51 is opened, and the corresponding heat storage tank 3 is communicated with the atmosphere, so that the interior of the heat storage tank 3 is at zero pressure. When the pressure value in the second pressure relief channel 6 is greater than the pressure threshold value of the second pressure relief valve 61, the second pressure relief valve 61 is opened, and at this time, the heat storage tank 3 is exhausted from the water outlet end 2.
It should be noted that the pressure threshold of the first pressure relief valve 51 is smaller than the pressure threshold of the second pressure relief valve 61, that is, normally, the first pressure relief valve 51 is opened preferentially, and the heat storage tank 3 is communicated with the atmosphere through the first pressure relief passage 5. Under the condition that first relief valve 51 is unusual or first pressure release passageway 5 blocks up, the pressure in second pressure release passageway 6 can continuously rise, and when the pressure in second pressure release passageway 6 was greater than the threshold value of second relief valve 61, second relief valve 61 opened to make heat storage tank 3 communicate with the atmosphere through second pressure release passageway 6. This embodiment plays duplicate protection's effect through setting up two pressure release passageways to avoid first relief valve 51 inefficacy back, suppress the pressure in pressure release passageway and the hot pot, cause pipeline, hot pot to burst, perhaps high-pressure gas strikes when user's water intaking, causes the user to scald the scheduling problem.
In an alternative embodiment of the present invention, based on the above-described embodiment, the control valve 4 is a reversing mechanism (e.g., a reversing valve) having an inlet end, an exhaust outlet end, and a drain outlet end. The inlet end is communicated with the heat storage tank 3, the exhaust outlet end is connected with the pressure relief channel, and the drainage outlet end is in adaptive connection with the water outlet channel 21. The reversing mechanism is connected with a control module (such as a PLC controller, a PCB and the like), and the control module is triggered in an operable mode to drive the inlet end of the reversing mechanism to be switched between the conduction with the exhaust outlet end and the conduction with the drainage outlet end. When the inlet end is communicated with the exhaust outlet end, the heat storage tank 3 is communicated with the pressure relief channel, and when the inlet end is communicated with the drainage outlet end, the heat storage tank 3 is communicated with the water outlet end 2.
Preferably, the first relief valve 51 and the second relief valve 61 are both one-way valves, wherein the pressure threshold of the first relief valve 51 is set to zero. Namely, the heat storage tank 3 is always communicated with the atmosphere when hot water is not discharged from the water outlet end 2, so that zero pressure is always kept in the heat storage tank 3, and the risk of pipe explosion is further reduced. In addition, the relief valve adopts the check valve, can avoid in each passageway and the heat storage tank 3 is backward discharged into to external dust or granule etc. to cause water pollution.
In another embodiment, the water outlet end 2 is provided with a switch 7 for triggering a control module, such as an infrared sensor, a human-computer interface, etc. Preferably, the system is a man-machine interface, buttons and the like are arranged on the man-machine interface, and a user can select cold water or hot water through the man-machine interface. When a user selects cold water, the trigger control module drives the first electromagnetic valve 111 to open, and at this time, the water inlet end 1 is communicated with the water outlet end 2 through the cold water inlet flow channel 11. When a user selects hot water, the trigger control module drives the second electromagnetic valve 121 to be opened and the inlet end and the drain outlet end of the reversing mechanism to be communicated, at the moment, the water inlet end 1 is communicated with the heat storage tank 3, and the heat storage tank 3 is communicated with the water outlet end 2.
The heat storage tank 3 is provided with a heating rod and a temperature sensing probe which are electrically connected with the control module. The temperature range in the heat storage tank 3 is preset, and when the temperature detected by the temperature sensing probe is lower than the minimum value of the temperature range, the control module drives the heating rod to heat to the maximum value of the temperature range and then stops. Thereby ensuring the water temperature in the heat storage tank 3 and facilitating the use at any time.
It should be mentioned that other parts not mentioned in this application are prior art, and are not described herein in detail, such as the machine body, the arrangement inside the machine body, the faucet, etc.
The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
