The working principle of the present utility model is as shown in Figure 3.

In the cooker unit, a flameout protection device (temperature control probe 12) is provided. When the flame goes out abnormally, in order to ensure that the gas does not leak, the flameout protection device detects that there is no flame, and automatically closes the gas valve. When the stove is working normally, there is a medium, that is, the food or water in the pot, which absorbs the heat energy generated by the stove, so that the temperature of the pot itself will not be too high. But when there is no food or water in the pot, or the food is boiled dry, the medium in the pot can no longer absorb the heat energy, which will cause the temperature of the pot itself to rise sharply, causing the pot to be burned through, or even cause a fire and other more serious consequences. . Now the temperature control probe 12 of the utility model has just worked, and by setting the operating temperature of the temperature sensor, only if the temperature sensor detects that the temperature is within the set safe temperature, the gas valve is kept open. When it captures abnormal temperature and the temperature is higher than the set safety test value, the control unit sends an instruction to cut off the gas circuit in time to prevent the occurrence of hazards. In the daily use of the cooker, not 100% of the large amount of heat energy generated by the cooker is really absorbed and utilized, and 30 to 40% of the heat energy is wasted. In order to effectively utilize these wasted heat energy, the heat collecting device arranged around the stove burner collects heat through water circulation and utilizes it. When the cooking range is not working, the water is also not flowing. After the cooker starts to work, when the above-mentioned temperature sensor detects a high but normal flame temperature, it controls the control unit to turn on the water pump to realize the water circulation, and when the detected temperature is not within the set range, the water circulation is turned off. This function is the second function of the temperature sensor (temperature control probe 12), that is, the above-mentioned temperature sensor integrates two functions of preventing overheating and opening the circulating water pump. The waste heat collected above can be used for kitchen cleaning water, washing water, etc., and the collected hot water is stored in a waste heat collection water tank 13 placed under the cooker. When domestic water is used, when the water temperature in the waste heat collection water tank 13 reaches the set value, the internal temperature sensor notifies the control unit to open the water outlet valve 39 on the waste heat collection water tank 13, and the hot water used is provided by the collected waste heat. to save energy. When the temperature of the hot water produced by collecting waste heat does not meet the needs, close the water outlet valve 39 of the waste heat collection water tank 13, open the water heater water outlet valve, and use the hot water produced by the main burner.

In the range hood unit, the bottom of the traditional range hood is a structure with one side against the wall and three sides open. When working, with a certain fan suction, the oil fume is dispersed from three sides, and the suction on all sides is weakened. While ensuring that all structures and functions are the same as those of the existing products on the market, the utility model adds a side baffle on the left and right sides below the range hood. In this way, the side baffles on the two sides and the wall on the back form a semi-closed structure with three sides closed and one side open. Under the action of the same fan, the suction absorbs air completely entering from the open part below, which greatly enhances the oil fume absorption effect. At the same time, the depth of the range hood can be reduced, avoiding potential safety hazards that users may touch their heads during use of existing products on the market, which is safe and beautiful. In the case of cooking with less oily smoke such as soup, using the traditional range hood, even if it works at low power, there is still a lot of noise. Pull down the front baffle to form a closed space under the range hood with only openings on the front side, so that all the fume can be discharged with only a small negative pressure. Therefore, the range hood of the utility model can work at a lower power, save energy, and have low noise at the same time. The front baffle is made of transparent material, through which the user can see the working conditions on the stove during the cooking process. It can be put away when not needed. In order to share the exhaust channel with the water heater, the range hood is designed as a multi-channel range hood, but it shares one air outlet to avoid multiple drilling and installation of the chimney channel. The waste gas produced by the water heater is exhausted through the range hood fan. When only the water heater is working, the fan of the range hood operates at a lower speed, which is sufficient to exhaust exhaust gas and reduce noise at the same time. When the user is cooking, turn on the medium and high speed gears of the range hood to meet the effect of exhausting the range hood.

The water heater unit is placed at the rear lower part of the stove cabinet 5, thus avoiding the unreasonable use of space and the destruction of the overall aesthetic feeling of the traditional separate installation. The water heater is equipped with a hot water heating device, which can realize functions such as home heating, bathing, washing, and warm water for kitchen cleaning. When the water heater needs to be used to provide hot water, the user turns on the faucet, and the control system, such as the water-air linkage valve, receives the signal of water flow, automatically turns on the range hood, and ensures that the range hood operates at a low speed to meet the exhaust gas generated by the water heater. to reduce noise pollution. Under the action of the range hood, the combustible gas that may remain in the combustion chamber is discharged to prevent accidents during ignition and ensure user safety. Then, after a few seconds, the ignition system automatically ignites the burner. When the burner goes out due to abnormal conditions, the flame detector installed above the burner will immediately cut off the gas source through the control system to avoid danger. After turning off the water heater, the fan of the range hood continues to run for a few seconds to ensure that the harmful gas in the combustion chamber is discharged from the room in time and then automatically shuts down. The temperature of the hot water provided by the water heater can be adjusted. There are two choices of water in winter and water in summer. At the same time, the size of the flame and the amount of hot and cold water can be adjusted automatically by water or by the control system to ensure the stability of the water temperature for users. When the user uses the system for home heating, the water heater provides another independent circulating water circuit, and a temperature sensor is installed at the hot water outlet of the heating system to facilitate the control of the heating temperature to the temperature set by the user. When the heating temperature reaches the temperature set by the user, the water heater stops working. When the temperature is lower than the set temperature, the water heater will re-ignite to provide heat. At the same time, an expansion tank is provided to adjust the internal pressure of the heating system.

When the water heater is working, a large amount of high-temperature gas flows through the flue. This will be a great waste of energy, so the utility model also adds a condensing waste heat collection device in the flue system, and fully absorbs the high temperature in the flue through the condensing waste heat collection device, so that the temperature at the air outlet is kept at 50 Celsius or even lower. The water circulation in the waste heat collection device is: cold water enters from the top of the device and circulates downward to fully absorb the waste heat in the flue. When the water circulates to the main heat exchanger, the water temperature has been raised to a higher temperature by the waste heat. After entering the main heat exchanger, under the action of the burner, the water temperature is further heated for use. Because the water entering the main heat exchanger already has a relatively high water temperature, the power of the burner needs to be large to meet the needs, thereby achieving the purpose of energy saving. The flue and the internal waste heat collection device are assembled as a whole, which is convenient for users to install. The waste heat collected in the flue will cause water vapor to condense into water droplets. A cold water collection device and a water neutralization device are installed under the flue, and the collected cold water is discharged into the household drainage system after neutralization to meet environmental protection requirements. Because the hot water heating device of the present utility model is different from the traditional boiler, the size of the heat exchange device of the traditional boiler is limited due to limitations such as volume. In this system, the water heater is set at the bottom, the flue is very high, and there is a large space at the rear of the whole system to install the heat exchange device, so the heat utilization rate of this system is much higher than that of the existing boilers in the market. In order to prevent the water in the waste heat collection device from freezing when the water heater is not used for a period of time in winter, a temperature sensor can be installed on the circulation pipe of the waste heat collection device. It will work automatically and turn on the water circulation pump at the same time; when the water temperature is higher than the freezing critical temperature, the electric heater will stop working and turn off the water circulation pump.

In the oven unit, whether it is an electric oven or a gas oven, during use, a large part of the heat is dissipated to cause waste. In traditional ovens, in order to avoid the harm caused by high temperature, the current products are all made of heat insulation materials at the heat dissipation points. This part of heat cannot be effectively utilized like this. In the new system, a heat collecting device is arranged above the oven, which is similar to the above heat collecting device. The switch of the circulating water pump is controlled by a temperature sensor, and the collected waste heat is stored in the collection water tank in the form of hot water. At the same time, a heat insulation layer is arranged on the rear side of the heat collecting device close to the outside of the water heater to prevent the high temperature of the water heater from affecting the performance and life of the oven. In addition, the oven unit can be replaced with dishwashers, gas ovens, electric ovens, cupboards and other equipment according to the actual needs of customers.

Other constituent units in the utility model can also be combined by products with the same function in different shapes selected by the user's preferences. The front adopts an integral panel with a blue background light behind all operating parts. After the panel is opened, the disinfection cabinet unit can be replaced and all internal water, electricity and gas connections can be made. The cold water inlet and hot water outlet are set on the side of the system; the total air source inlet is also set on the side. In order to still use other units when replacing and maintaining different units, independent valves are provided at the internal connections with each unit.
