Description

Technical Field

[0001] The utility model relates to the technical field of hot drink equipment, in particular to a hot drink equipment utilizing waste water. Background Art

[0002] In hot drink equipment, there is usually a long pipe between the heated drinkable liquid and the liquid outlet. For example, in a heated water dispenser, there is a long water channel between the heated kettle and the water outlet. When the water channel has not circulated for a long time and hot water has not been output, when the user takes water through the water outlet, the outlet water temperature is often inaccurate or low. On the one hand, a small amount of cooled water may be retained in the water channel. On the other hand, when the hot water first passes through the water channel, the water channel pipe temperature is relatively low, which absorbs the heat of the hot water, causing the hot water to cool down quickly. In addition, the water retained in the water channel is prone to breeding bacteria over a long period of time due to its low temperature and stagnation. Even if there is no excess liquid accumulated in the water channel, it is easy to breed bacteria. Therefore, under the influence of many of the above reasons and other reasons, users usually treat the first cup of water they get as "waste water" and throw it away.

[0003] In order to facilitate users to drink cleaner and more accurately heated water, some manufacturers have added a wastewater channel to the waterway. Before the user drinks the water, the wastewater can be discharged to the wastewater tank through the wastewater channel, without the need for the user to frequently pour the water. However, due to the fact that existing hot drink equipment is usually small in size, the storage space and volume of the wastewater tank are relatively limited, and it is impossible to store too much wastewater. Users still need to clean the wastewater in the wastewater tank relatively frequently. In addition, the above-mentioned wastewater is not dirty water or sewage in the conventional sense. It is just that the standard is not as high as that of pure water after heating and high-temperature sterilization, or it does not meet the higher standards of users, but it is still usable domestic water and can even still be used as drinking water. If it is directly poured out for disposal, it is relatively wasteful and not environmentally friendly. Summary of the Invention

[0004] In response to the problems in the related art, the utility model proposes a hot drink device that utilizes wastewater, which can reduce the frequency of users cleaning the wastewater stored in the wastewater tank, improve the utilization rate of wastewater, and be more environmentally friendly.

[0005] The utility model is achieved in this way:

[0006] A hot drink device utilizing wastewater, comprising a hot water outlet device, a main water outlet pipeline, and a water outlet nozzle; the water inlet end of the main water outlet pipeline is connected to the hot water outlet device, and a first pipeline and a second pipeline are provided at the water outlet end, wherein the first pipeline is connected to the water outlet nozzle;

[0007] It also includes a water pump, a first solenoid valve and a wastewater collection container; the end of the second pipeline is connected to the wastewater collection container; the first solenoid valve is arranged on the second pipeline; the water pump is arranged on the water outlet main pipeline;

[0008] It also includes a reflux waterway; one end of the reflux waterway is connected to the wastewater collection container; the other end of the reflux waterway is connected to the main water outlet pipeline and is located before the water pump; the reflux waterway is a one-way flow channel, and the liquid passing through the reflux waterway only flows from the wastewater collection container to the main water outlet pipeline.

[0009] Through the cooperation of the water pump and the first solenoid valve, the hot water output by the hot water outlet device can be used to clean, sterilize and preheat the main water outlet pipeline, that is, to complete the treatment of most of the water channels of the entire hot drink device between the hot water outlet device and the water outlet, and at the same time, the cleaned wastewater is discharged to the wastewater collection container. At this time, the wastewater is not as high as the standard of high-temperature pure water, but it is still domestic water that can be used normally, rather than dirty water or sewage in the conventional sense. By leading the wastewater to the main water outlet pipeline through the reflux water channel, the wastewater can be reused, and the main water outlet pipeline can be preliminarily cleaned with wastewater. At this time, only a smaller amount of hot water is needed to complete the above-mentioned "cleaning, sterilization and preheating", and the user does not need to frequently clean the wastewater in the wastewater collection container.

[0010] As a further optimization of the above solution, a check valve is provided on the reflux waterway so that the liquid passing through the reflux waterway only flows from the wastewater collection container to the main water outlet pipeline.

[0011] As a further optimization of the above solution, a second solenoid valve is provided on the return water path; the second solenoid valve is closer to the starting end of the return water path than the check valve.

[0012] When the waste water collection container is separated from the hot beverage device, the second solenoid valve is closed to prevent a large amount of accumulated liquid in the return water path from leaking.

[0013] As a further optimization of the above scheme, a wastewater outlet is provided at the bottom of the wastewater collection container, and the wastewater outlet is connected to the starting end of the reflux waterway; a valve is provided at the wastewater outlet; when the wastewater collection container is separated from the reflux waterway, the valve is automatically closed; when the wastewater collection container is connected to the reflux waterway, the valve is automatically opened.

[0014] As a further optimization of the above solution, a support baffle is further provided on the inner side of the wastewater collection container, and a movable cavity is provided between the support baffle and the wastewater outlet;

[0015] The valve further comprises a movable member, wherein the movable member is partially or entirely disposed in the movable cavity; a spring is disposed between the movable member and the support baffle; two ends of the spring respectively abut against the movable member and the support baffle, so that the movable member blocks the wastewater outlet; the movable member, the spring, the movable cavity, and the support baffle cooperate with each other to form the valve;

[0016] When the wastewater collection container is connected to the hot beverage device, the movable part abuts against the mating position surface of the hot beverage device, compressing the spring to form a water gap between the movable part and the wastewater outlet, and the water gap is connected to the reflux waterway and the inner cavity of the wastewater collection container.

[0017] As a further optimization of the above solution, the wastewater outlet is a cylindrical structure; the movable member is a columnar structure; the movable member reciprocates along the wastewater outlet; a limiting portion protruding toward the outer circumference is provided at one end or near one end of the movable member; the limiting portion is placed in the movable cavity;

[0018] When the wastewater collecting container is separated from the reflux waterway, the limiting portion blocks the wastewater outlet.

[0019] As a further optimization of the above solution, when the wastewater collection container is separated from the reflux waterway, the outward end of the movable part protrudes outward and extends out of the wastewater outlet;

[0020] Alternatively, the hot drink device is provided with a convex portion at the position where it cooperates with the waste water collection container; when the waste water collection container is connected to the hot drink device, the convex portion abuts against the movable part and compresses the spring.

[0021] As a further optimization of the above solution, a filtering unit is further provided at the wastewater outlet.

[0022] As a further optimization of the above solution, the wastewater collection container is a wastewater box or a wastewater tank; after the wastewater collection container is assembled with the hot beverage device, the internal cavity of the wastewater collection container is in a sealed state isolated from the external environment.

[0023] As a further optimization of the above solution, the wastewater collection container is a water receiving box; the top of the water receiving box is open and is located directly below the water outlet.

[0024] Furthermore, the hot water outlet device is a kettle; or a heating pipe, wherein the water inlet end of the heating pipe is connected to the water tank.

[0025] The beneficial effects are as follows:

[0026] This utility model provides a hot drink device that utilizes wastewater. Through the cooperation of a water pump, a first solenoid valve, and a return water channel, wastewater is directed to a main water outlet pipe. The main water outlet pipe is initially cleaned with the wastewater, and then a small amount of hot water is used to clean, sterilize, and preheat the majority of the water channel between the hot water outlet and the water outlet in the hot drink device. Ultimately, this improves wastewater utilization and is more environmentally friendly. It also reduces the frequency with which users must clean wastewater from the wastewater collection container, ensuring that the temperature and cleanliness of the hot water obtained by the user meet the required standards.
