Background

With the improvement of living standard of people, in a home or office scene, an instant heating type water dispenser is often equipped. The instant heating type water dispenser is fast in heating and short in waiting time of water heating, and is popular with users, such as tea making, coffee making and other types of infusion.

In a conventional instant heating type water dispenser, a heating element (such as a heating tube) is generally disposed in a pipeline for liquid to flow through, and when the liquid flows through the pipeline with the heating element, the liquid is heated by the heating element, so that the heated liquid is obtained at an outlet end of the pipeline. The traditional instant heating type water dispenser has the following defects:

1. since it takes time for the heating element to heat the liquid, the heating time of the liquid needs to be compressed in order to ensure the water outlet efficiency (i.e. to ensure that the flow rate of the liquid cannot be lower than the preset value), so the upper temperature limit for heating the liquid is limited. For example, if a user needs hot water at a temperature close to 100 ℃, the hot water obtained by heating a common instant heating type water dispenser can only reach 80-90 ℃ and cannot meet the requirements of the user.

2. When the liquid flows out of the pipeline, the subsequent heat supply is lost, namely the heat preservation function is not realized.

Therefore, a new instant heating type water dispenser needs to be developed, which can increase the heating temperature of the liquid and has a heat preservation function on the premise of ensuring the water outlet efficiency.

As shown in fig. 1 to fig. 6, it is an instant heating type water dispenser 100 according to an embodiment of the present invention.

As shown in fig. 1 and fig. 6, the instant heating type water dispenser 100 includes: a primary heating assembly 10, a secondary heating assembly 20, and a controller 30 connected to the primary heating assembly 10 and the secondary heating assembly 20, respectively. The primary heating assembly 10 is an instant heating module, and is used for primarily heating liquid. The secondary heating assembly 20 is used for receiving and carrying the liquid after primary heating, and under the control of the controller 30, secondary heating is performed on the liquid after primary heating according to the difference between the temperature after primary heating of the liquid and the target temperature preset by the user, so that the temperature of the liquid can be further increased to reach the preset target temperature.

The above-described tankless water dispenser 100 will be further described with reference to fig. 1 to 6.

As shown in fig. 2 and 3, the primary heating assembly 10 includes: the water pump 11, a pipeline 12 connected with the water pump 11, a first heating body 13 arranged on the pipeline 12, and a first temperature sensor 14 arranged on the pipeline 12. The water pump 11 is used for connecting a water source to pump liquid and deliver the liquid to the pipeline 12, and when the liquid flows through the pipeline 12, the first heating body 13 heats the liquid, so that instant heating type primary heating is realized on the liquid. The pipe 12 is provided with a water outlet 121 through which the liquid flows out, and the first temperature sensor 14 is located at the water outlet 121 to detect the temperature of the liquid after the liquid is heated once.

As shown in fig. 2 and 3, in the present embodiment, the primary heating assembly 10 may further include: an air pump 15 connected to the pipe 12. The air pump 15 is located between the water pump 11 and the pipe 12, and the air pump 15 is used to generate an air flow into the pipe 12 to reduce the liquid remaining in the pipe 12. After the liquid heating is completed, the air flow generated by the air pump 15 can blow out the liquid remained in the pipeline 12 or accelerate the evaporation of the liquid remained in the pipeline 12, so that the residual quantity of the liquid in the pipeline 12 is reduced, the probability of bacterial growth reduction is facilitated, and meanwhile, the accuracy of controlling the total conveying capacity of the liquid is also facilitated to be improved, and the control accuracy of the heating temperature of the liquid is facilitated to be improved.

Further, it is considered that the air pump 15 may introduce foreign substances in the external air into the duct 12 when generating the air flow, thereby causing contamination of the liquid. Thus, in some embodiments, the air intake end of the air pump 15 may be provided with an air filter. The air filter can intercept foreign substances in the air introduced into the air pump 15, preventing the generated air flow from introducing the foreign substances into the duct 12.

As shown in fig. 6, the secondary heating assembly 20 includes: a kettle 21, a second heating element 22 mounted on the kettle 21, and a second temperature sensor 23 mounted on the kettle 21. The kettle 21 receives liquid discharged from the water outlet 121. In this embodiment, the kettle 21 is disposed below the water outlet 121 of the pipe 12, and the top of the kettle 21 is provided with an opening, so that when the liquid after the heating is finished flows out from the water outlet 121 of the pipe 12, the liquid falls into the kettle 21 under the action of gravity. In other embodiments, a flow guide tube connecting the water outlet 121 and the water bottle 21 may be provided.

As shown in fig. 6, the controller 30 is electrically connected to the water pump 11, the first heat generating body 13, the first temperature sensor 14, the second heat generating body 22, and the second temperature sensor 23, respectively. The controller 30 controls the second heating element 22 to heat the liquid in the kettle 21 for the second time according to the temperature value fed back by the first temperature sensor 14, and feeds back the temperature value of the liquid in the kettle 21 through the second temperature sensor 23 to adjust the working state of the second heating element 22.

As shown in fig. 4 and 5, an implementation of a kettle 21 is provided. This kettle 21 includes: a base 211 and a kettle body 212 detachably connected to the base 211. As shown in fig. 6, the second heating element 22 and the second temperature sensor 23 are both installed at the bottom of the kettle body 212, and the second heating element 22 and the second temperature sensor 23 are indirectly electrically connected to the controller 30 through the base 211. The kettle body 212 and the base 211 are detachable, so that a user can pour liquid conveniently and clean the kettle body 212 conveniently.

Since the kettle 21 needs to store heated liquid, it is easy for a user to burn if touched by mistake, so that some targeted changes can be made. For example, in some embodiments, the outer peripheral side of the kettle body 212 may be provided with a heat insulating plate. The heat insulation plate can insulate the liquid in the kettle body 212, and is favorable for reducing the risk that a user is scalded by mistakenly touching the kettle body 212. For another example, as shown in fig. 4 and 5, in the present embodiment, a handle 2121 may be disposed at one side of the kettle body 212. The handle 2121 can be held by a user, so that the user is prevented from directly contacting the kettle body 212, and the probability of scalding is reduced.

In order to allow the user to intuitively know the temperature of the liquid in the kettle 21, in some embodiments, the secondary heating assembly 20 may further include: a temperature display screen mounted on the kettle 21. The temperature display screen is electrically connected with the second temperature sensor 23 to display the temperature of the liquid in the kettle 21 in real time. The temperature display screen can enable a user to observe the temperature of the liquid in the kettle 21 in real time, so that the current temperature of the liquid can be known visually.

As shown in fig. 1 to fig. 3, in the present embodiment, the instant heating type water dispenser 100 may further include: a water tank 40 connected with the water pump 11. The water tank 40 is connected with the water inlet end of the water pump 11. The water tank 40 may store a water source for the user to use at any time.

Further, the tankless water dispenser 100 may further include: a third temperature sensor 50 located at the bottom of the water tank 40. The third temperature sensor 50 is electrically connected to the controller 30. The third temperature sensor 50 can detect the temperature of the liquid in the water tank 40, which is equivalent to the initial temperature of the liquid, and in combination with the control of the controller 30, can perform more precise control on the water pump 11 and the first heating element 13 according to the temperature difference between the initial water temperature and the target water temperature set by the user and the amount of the heated liquid, thereby improving the control precision of the heating temperature of the liquid.

In addition, in order to facilitate the user operation, in some embodiments, the instant heating type water dispenser 100 may further include: a touch screen connected to the controller 30. The touch screen can improve the convenience of user operation and improve user experience.

It should be noted that, as shown in fig. 6, in the present embodiment, the controller 30 is integrated in the base 211 of the kettle 21, and accordingly, the touch screen may be disposed at a side portion of the base 211. In other embodiments, the base 211 and the controller 30 may be integrated into a single body and may be in the form of a panel.

The working principle is briefly described as follows:

in operation, as shown in figure 5, the water pump 11 draws liquid from a water supply and delivers it to the pipe 12. When the liquid flows through the pipeline 12, the first heating body 13 heats the liquid once, and the heated liquid flows into the kettle 21 from the water outlet 121 of the pipeline 12. The first temperature sensor 14 feeds back the temperature of the liquid after the first heating to the controller 30, and if the temperature of the liquid after the first heating is lower than the target temperature preset by the user, the controller 30 controls the second heating element 22 in the kettle 21 to heat the liquid for the second time until the temperature value of the liquid fed back by the second temperature sensor 23 reaches the preset target temperature. The second temperature sensor 23 can monitor the temperature of the liquid in the kettle 21, and the liquid can be heated and kept warm by the second heating element 22. For example, when the target water temperature preset by the user is 100 ℃, the upper limit of the temperature of the liquid after the liquid is heated for one time is 90 ℃, and after the liquid leaves the pipe 12 and flows into the kettle 21, the liquid is heated for the second time by the second heating element 22 in the kettle 21 until the temperature of the liquid reaches 100 ℃. When the user needs to keep warm, the liquid can be heated by the second heating body 22 to maintain the temperature.

It should be noted that if the target water temperature preset by the user is lower, that is, the primary heating unit 10 can heat the liquid to the target water temperature, the liquid does not need to be heated again when entering the water bottle 21.

In addition, secondary heating element 20 also can regard as traditional electric kettle to use, simultaneously, for traditional electric kettle, this scheme has compensatied traditional electric kettle can not the quantitative not enough of heating up water.

Moreover, the mechanism that can realize twice heating is arranged in this scheme, and more accurate control can be realized to the temperature of liquid.

The instant heating type water dispenser 100 realizes instant heating type primary heating of liquid by using the primary heating component 10, and then realizes secondary heating of the liquid by using the secondary heating component 20 capable of storing the liquid, thereby correcting the heating temperature of the liquid, improving the reachable heating temperature of the liquid on the premise of ensuring the water outlet efficiency, and having the heat preservation function.

All possible combinations of the technical features in the above embodiments may not be described for the sake of brevity, but should be considered as being within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above examples only represent preferred embodiments of the present invention, which are described in more detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
