Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to an automatic cleaning brewer device. Background Art

[0002] At present, many fully automatic coffee machines on the market have coffee powder easily hidden in the brewer inlet, which is even more serious after making coffee many times. The coffee powder hidden in the brewer inlet not only affects the appearance and hygiene, but also causes mold and odor if it is not cleaned overnight. Re-making coffee will affect the flavor and quality of the coffee, and even endanger human health. Some coffee machines on the market now allow you to manually clean the brewer after making coffee.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN116548816A discloses a coffee brewing system and coffee machine that are easy to clean. The coffee brewing system includes a brewing seat and a brewing chamber assembly, the brewing chamber assembly includes a sliding seat and a brewing head (i.e., a brewer) disposed on the sliding seat, the brewing head is detachably connected to the sliding seat, and the coffee brewing system also includes: a fixed bracket, which is arranged opposite to the brewing seat; a connecting rod assembly, which is used to connect the brewing seat and the fixed bracket to form a machine body together, the machine body is detachably connected to the coffee machine, the sliding seat is connected to the connecting rod assembly, and can move relative to the connecting rod assembly in a direction close to or away from the brewing seat to allow the brewing head to dock or separate from the brewing seat. The coffee brewing system can be convenient for users to disassemble and clean it as a whole, but such a brewer is troublesome to disassemble and clean, and consumers often forget to clean it.

[0004] Therefore, the above-mentioned prior art needs to be improved and developed. Utility Model Content

[0005] In view of the above technical problems existing in the prior art, the utility model provides an automatic brewer cleaning device, which can realize automatic cleaning of the powder inlet of the coffee machine brewer.

[0006] In order to achieve the above object, the utility model is implemented through the following technical solutions:

[0007] The utility model provides an automatic cleaning brewer device, comprising a brewer and a brewing seat, the brewer and the brewing seat are arranged relatively to each other and work in coordination, specifically, the brewer and the brewing seat are installed at the left and right ends of a body of the coffee machine, the brewing seat is fixed to the left end of the body, the brewing seat is installed at the right end of the body through a sliding mechanism, the brewing seat is connected to a driving mechanism, and the brewer can be moved back and forth in a straight line along the direction of the brewing seat in coordination with the sliding mechanism by controlling the driving mechanism, and the direction in which the brewer slides toward the brewing seat is set as the forward direction, and the brewing seat is connected to the driving mechanism by controlling the driving mechanism. The direction in which the brewer slides away from the brewing seat is the backward direction, a brewing cavity is provided in the brewer, and the end of the brewing cavity opposite to the brewing seat is open, and the brewing cavity is also provided with a powder inlet connected to the brewing cavity. When it is necessary to brew coffee, the driving mechanism is controlled to move the brewer forward until the end of the brewing head away from the machine body blocks the open opening of the brewing seat, and when the powder drop port of the coffee machine grinding mechanism corresponds to the powder inlet, the coffee machine automatically adds coffee powder, and successively completes the extrusion and brewing of the coffee powder. This part belongs to the prior art and will not be described in detail.

[0008] The utility model also includes a flushing head, which is also installed in the body of the coffee machine. Preferably, the flushing head is located in front of the powder drop port of the coffee machine's grinding mechanism. The flushing head is provided with a water inlet and a water outlet. The water inlet is connected to a water inlet pipe, and the water outlet matches the powder inlet. When the coffee is made or the coffee needs to be flushed before making the coffee, the flushing water enters from the powder inlet and flows out from the open port, that is, the driving mechanism is controlled to make the brewer slide to the bottom of the flushing head, and the water outlet of the flushing head is docked with the powder inlet. The coffee machine automatically supplies water to the flushing head, and the flushing water flushes the powder inlet and the inside of the brewing cavity. After flushing, the driving mechanism is controlled to move the brewer backward, and the brewing seat is separated from the open port of the brewing cavity. The sewage flows down from the open port. If the coffee is cleaned after making the coffee, the coffee grounds and the sewage can fall together. Through the above-mentioned structural setting, the automatic cleaning of the powder inlet of the brewer can be realized, and the brewer does not need to be frequently disassembled for manual cleaning, which can meet the needs of consumers.

Through the above structural setting, flushing water can quickly reach the water outlet after entering the water inlet cavity from the water inlet, which reduces the cleaning time accordingly and provides a better user experience.

[0011] According to the above solution, the bottom of the lower cover is set to a structure concave toward the middle. Through the above structure, when flushing, the concave bottom of the lower cover is more conducive to the downward flow of flushing water, speeding up the flushing of the powder inlet, and after flushing, it is not easy to accumulate water at the bottom of the lower cover.

[0012] According to the above scheme, the plurality of water outlet holes are arranged in one circle or several circles. Through the above structural arrangement, the surroundings of the powder inlet can be fully cleaned.

[0013] According to the above scheme, the bottom of the lower cover is provided with a plurality of drainage grooves in the circumferential direction, and the drainage grooves correspond to the water outlet holes one by one. Through the above structural arrangement, the flushing water can be drained to the edge of the powder inlet, which is beneficial to the flushing of the powder inlet and can effectively prevent the flushing water from leaking out.

[0014] According to the above solution, the end of the water inlet pipe away from the flushing head is connected to a water pump. Through the above structural arrangement, the flushing power of the flushing water can be enhanced.

[0015] According to the above solution, a water receiving box for receiving flushing wastewater is provided below the brewer. Through the above structural arrangement, the water receiving box is also the coffee grounds receiving box of the coffee machine, and flushing can be completed without changing too much structure in the coffee machine.

This part belongs to the prior art, and the powder push rod is mainly used to compact the coffee powder and push out the coffee grounds after the coffee is prepared. After the flushing head is added to the utility model, the powder push rod can achieve a water scraping effect in the brewing cavity while pushing the coffee grounds, making the brewing cavity cleaner.

[0017] The beneficial effects of the utility model are:

[0018] When the utility model needs to be rinsed after making coffee or before making coffee, the driving mechanism can be automatically controlled to make the brewer slide to the bottom of the rinsing head, the water outlet of the rinsing head is connected with the powder inlet, and the coffee machine automatically supplies water to the rinsing head, and the rinsing water rinses the powder inlet and the inside of the brewing cavity. After rinsing, the driving mechanism is controlled to move the brewer backward, and the brewing seat is separated from the open mouth of the brewing cavity, and the sewage flows down from the open mouth. If it is cleaned after making coffee, the coffee grounds and the sewage can fall together. In this way, the powder inlet of the brewer can be automatically cleaned, and the brewer does not need to be frequently disassembled for manual cleaning, thereby improving the user experience.
