Description

Home Kitchen Energy Saving Drinking Water System

technical field

The utility model relates to a family kitchen energy-saving drinking water system combining solar energy and a water dispenser.

Background technique

As people's pursuit of quality of life is getting higher and higher, the traditional drinking fountains are not energy-saving and unhealthy, which has become a short board restricting social harmony and sustainable development. Traditional water dispensers mainly have the following three problems: First, repeated heating of drinking water leads to increased energy consumption; second, the "thousand-boiling water" formed by repeated heating will endanger human health; Existence, the air around the water dispenser will enter the bucket without any treatment, and the bacteria brought in by the air will continue to multiply, causing secondary pollution. Therefore, research on healthy and energy-saving drinking water products is very important. The utility model relates to a device combining solar energy and a water dispenser. Although the multifunctional solar water dispenser with the patent No. 201510108776. The problem of repeated heating, the repeated heating of drinking water in the solar water heater pipeline will also cause the nitrite content to increase, which is harmful to health.

Utility model content

In order to overcome the problem that the drinking water in the existing multi-functional solar water dispenser is repeatedly heated by solar energy, a family kitchen energy-saving drinking water system is provided, in which the purified tap water can be indirectly heated in a solar water storage tank through a heat exchanger, Instant drinking is purified and heated, avoiding repeated heating of drinking water in solar energy.

The utility model family kitchen energy-saving drinking water system is mainly composed of a solar water heater system, an elbow heat exchanger, a direct drinking machine, a cooling waste heat recovery device, a heat preservation water tank, a pressure sensor, a water level sensor and a purifier. It is composed of heat pipe, water storage tank and support.

The elbow heat exchanger is made of red copper, which is welded and surrounded in the solar water storage tank. After the purified drinking water (tap water) enters the heat exchange elbow, it is indirectly heated with the hot water in the solar water storage tank to avoid Drinking water is repeatedly heated in solar energy, increasing the nitrite content.

The direct drinking machine is a drinking water machine that can heat drinking water to boiling; the cooling waste heat recovery device is equipped with boiling water pipes, cold tap water pipes, and hollow pipes, the material of which is copper, and the boiling water pipes surround the hollow pipes , the inlet and outlet of the boiling water pipe are welded on the shell. The boiling water pipe flows the boiling drinking water heated by the direct drinking machine. The cold tap water pipe is composed of a shell and a hollow pipe. The cold tap water pipe flows cold tap water, hot water and The cold water flows countercurrently for indirect heat exchange.

The insulated water tank is equipped with a water level sensor and an electric heating wire. The insulated water tank is used to store warm tap water for cooling boiled water and make full use of the waste heat of cooling. The water level sensor is used to control the water level in the insulated tank. Hot water is available in the kitchen; pressure sensors are used to control the flow of drinking water and cooling water.

The beneficial effects of the utility model are: introducing a solar water heater to increase the initial temperature of the drinking water to be heated to realize energy saving, and meanwhile avoiding repeated heating of the drinking water in the solar water heater; changing the traditional heating method to realize instant drinking; introducing cooling waste heat Recycling device, make full use of energy.

Detailed ways

This embodiment will be described in detail below in conjunction with accompanying drawings 1-2.

This system is mainly composed of solar water heater system, direct drinking machine, cooling waste heat recovery device, heat preservation water tank, pressure sensor, water level sensor and purifier. As shown in Figure 1, when you need to drink 100°C boiling water (making tea or coffee), press the hot water button 7, the button is equipped with a pressure sensor 8, at this time the pressure sensor receives the pressure change, and the corresponding electric control valve 5 opens, After the tap water is filtered by the purifier 4, it flows into the elbow heat exchanger 3 in the solar water storage tank 2, and is indirectly heated by the hot water in the water storage tank 2 outside the tube, so that the drinking water is preheated before the water dispenser is heated. Effect. The indirect heating can prevent the filtered tap water from being heated repeatedly in the solar water storage tank 2, causing the nitrite content to increase. The filtered tap water after indirect heating enters a kind of instant hot drinking machine, direct drinking machine 6, is heated to 100 ℃ of boiling, directly connects from the hot water outlet.

When you need to drink warm water at 50°C (immediate drinking), press the warm water button 10, and the button 10 is also equipped with a pressure sensor 9. When receiving a pressure change, the electric control valves 5 and 11 are opened at the same time, and the filtered tap water enters At the same time as the elbow 3, the cooling tap water flows into the cold tap water pipe 17 in the cooling waste heat recovery device 12, and the filtered tap water is not directly connected after being heated and boiled through the above process, but enters the boiling water pipe 16 in the cooling waste heat recovery device 12, Indirectly cooled by the cold tap water in the cold tap water pipe 17, the boiling water is cooled to about 50°C, and enters the warm water outlet to connect. And the cooling water in the tap water pipe 17 absorbs heat and heats up, flows into the heat preservation water tank 14, and is used as kitchen washing water, when the residual heat recovered is not enough for kitchen washing, the water level sensor 15 sends a signal, and the electric control valve 13 opens, and the water comes from the solar water storage tank. 2 is replenished, and the incubator 14 is equipped with electric heating wires, which ensures that any weather in winter has hot water available in the kitchen. In this way, the initial temperature of the drinking water before being heated by the water dispenser is increased, energy is saved, and the quality of the drinking water is guaranteed.

Fig. 2 is the structural diagram of cooling waste heat recovery device, wherein 18 is a hollow pipe, plays a supporting role, also can avoid the cooling water quantity in the running water pipe 17 too much simultaneously, the cooling water temperature that flows into the incubator 14 is low.
