Description

Coffee machine with electric control circulating waterway Technical Field The utility model relates to a coffee machine with an electric control circulating waterway, which is internally provided with a circulating waterway suite containing a heater so as to facilitate heating of a brewing head. Background Coffee is a very popular beverage in modern life, and has a refreshing effect besides a unique flavor, so various coffee brewing devices with various styles are provided on the market by various factories according to different flavor requirements. With the development of technology and the maturation of the coffee brewing step, commercial coffee appliances are a good choice for many consumers to meet the needs of most people for coffee brewing. However, there are still some problems in the commercial coffee brewing apparatus, such as that the preheating of the brewing head is a very important issue for some consumers with high demands, however, when some coffee brewing apparatuses are used for preheating the brewing head, the operation steps are complicated for users, the water in the container is heated by using a heating device such as an alcohol burner or a picnic stove, the heated hot water flows to the brewing head and is discharged through the brewing head after the handle on the coffee brewing apparatus is operated, and if the water in the container is used, the water must be replenished again and heated, and the above steps are repeated until the brewing head reaches the ideal temperature, so that the preheating of the brewing head is completed. In the above, it can be seen that the conventional coffee brewing apparatus needs a complicated water replenishing and heating process to complete the preheating of the brewing head. Disclosure of utility model The utility model comprises a circulating waterway sleeve, and the circulating waterway sleeve can be utilized to carry out electric control circulating heating on the brewing head when the utility model is started, so that the operation of water supplementing and heating is not needed under the condition that the water tank is supplemented with enough water in the preheating process of the brewing head. The utility model provides a coffee machine with an electric control circulating waterway, which comprises a brewing head, a circulating waterway sleeve, a control module and a heater, wherein the brewing head comprises a water inlet part, a water outlet part and a brewing handle, the circulating waterway sleeve comprises a water outlet pipeline, a water return pipeline, a water tank, an electromagnetic valve, a water pump, a control module, a touch switch and the heater, the control module is electrically connected with the electromagnetic valve, the water pump, the touch switch and the heater, one end of the water outlet pipeline and one end of the water return pipeline are respectively communicated with the water tank, the other end of the water outlet pipeline and the other end of the water return pipeline are respectively communicated with the water inlet part, the electromagnetic valve is arranged on the water return pipeline, the water pump is arranged on one of the water outlet pipeline and the water return pipeline, the heater is arranged on the water outlet pipeline, wherein when the brewing handle is in a preheating state, the water inlet part and the water outlet pipeline are not communicated, and when the brewing handle is switched to a brewing state, the water inlet part of the brewing head is communicated with the water outlet pipeline, the water return pipeline is contacted with the control module, and the control module is blocked when the brewing handle is contacted with the control switch.
