Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a novel aseptic constant temperature boiled water drinking equipment. Background Art

[0002] At present, multi-faucet water heaters mostly use heat exchange to exchange heat and save energy, so as to achieve the purpose of changing boiled water into warm boiled water. When used in areas with large temperature differences, the temperature of the warm water outlet will change, and manual adjustment is required to control the temperature of the warm water outlet. In order to solve the above problems, technicians in this field have made the following improvements. For example, a Chinese patent, the authorization announcement number is CN216393819U, which discloses a step-by-step heating and non-pressure heat exchange system for constant temperature boiled water. By setting a first heat exchange device and a second heat exchange device, multi-stage heat exchange can be achieved, which is energy-saving and constant temperature water outlet, and a variety of water temperatures including boiled water can be obtained. However, when the water inlet temperature of this scheme fluctuates, the water outlet temperature of the water heater will also change accordingly and cannot be maintained within a constant range; in existing drinking water equipment, due to the difference in flow rate and pressure between different pipelines, this will cause changes in the water outlet temperature of different faucets. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a novel aseptic constant temperature boiled water drinking equipment.

[0004] The technical solution of the utility model is:

The constant temperature temperature control valve controls the outlet water temperature to remain stable according to the use requirements, solving the problem of unstable outlet temperature of warm boiled water caused by changes in the inlet water temperature of existing water heaters on the market; at the same time, the constant temperature temperature control valve also solves the temperature change problem caused by differences in pipeline flow rate and pressure in multi-faucet machines. Among them, the exchanger plays a role in heat transfer in the device; through the exchanger, the heat in the hot tank is cooled to 25-30℃ to generate cold boiled water, realizing the effective use of heat and energy saving; solving the problem of the increase in the outlet water temperature of warm boiled water and cold boiled water caused by seasonal changes, thereby causing scalding, and can increase the safety of equipment use; it can also solve the problem of manually opening the cover to manually adjust the outlet water temperature due to seasonal changes. In addition, according to the above-mentioned new aseptic constant temperature cold boiled water drinking equipment proposed by the utility model, it can also have the following additional technical features:

[0007] According to one embodiment of the utility model, the water inlet pipeline is provided with a water inlet solenoid valve, one end of the water inlet solenoid valve is connected to the water purifier, and the other end is connected to the exchanger; the pure water in the water purifier continues to enter the heat tank through the water inlet pipeline after heat exchange in the exchanger.

[0010] In this technical solution, the hot water pipeline serves as a channel for hot water to flow from the hot water tank to the hot water faucet, ensuring a stable supply of hot water; the hot water solenoid valve realizes the on-off of the hot water inlet pipeline, allowing users to easily control the outflow of hot water, ensuring the timeliness and stability of hot water supply, and improving the user experience.

[0012] In this technical solution, the boiled water solenoid valve responds quickly by controlling the boiled water pipeline, realizing the instant supply of boiled water and improving the user's drinking experience; through heat exchange, the exchanger transfers the heat in the hot water to the cold water, reducing its temperature to 25-30°C, thereby generating boiled water. This design is not only energy-efficient, but also ensures that the temperature of boiled water is suitable, meeting the drinking needs of users. The addition of the over-flow germicidal lamp I reflects the importance attached to water quality safety. When boiled water flows through the over-flow germicidal lamp I, it will be irradiated by ultraviolet rays, thereby killing bacteria, viruses and other microorganisms in the water, ensuring the hygiene and safety of boiled water; it is not only energy-efficient, but also ensures that the temperature of boiled water is suitable, meeting the drinking needs of users.

[0016] In this technical solution, the sterilization pipeline allows the 100°C hot water in the hot tank to flow through the cold boiled water pipeline and the warm boiled water pipeline for all-round sterilization and disinfection. The flow of hot water can not only effectively kill bacteria, viruses and other microorganisms in the pipeline, but also remove dirt and residues in the pipeline to ensure the cleanliness and hygiene of the pipeline. When sterilization is required, the sterilization solenoid valve is opened, and hot water enters the sterilization pipeline for sterilization; when sterilization is not required, the sterilization solenoid valve is closed to avoid the waste of hot water and energy loss, and improve the energy efficiency and service life of the equipment. In addition, the addition of the safety valve provides safety protection for the sterilization process. When the pressure in the sterilization pipeline exceeds the set value, the safety valve will automatically open to release excess pressure to prevent pipeline rupture or equipment damage, which fully considers safety performance. The sterilization solenoid valve is responsible for controlling the on and off of the sterilization pipeline.
