Description

Technical Field

[0001] The present invention relates to a water dispenser, specifically a thick film instant heating water dispenser. Background Art

[0002] Traditional water dispensers often need to be equipped with a large-capacity water tank. The heating device directly heats the water in the water tank. After the water in the water tank is heated to boiling, users can fetch water for drinking. Such water dispensers have the following disadvantages:

[0003] ① The amount of water in the water tank is relatively large. Directly heating the water in the water tank will result in high energy consumption, large power consumption, low heating efficiency, and high load on the heating device, so that it is prone to aging and damage; that is, traditional water dispensers have disadvantages such as high energy consumption, low heating efficiency, and short service life;

[0004] ② Whenever the water temperature in the water tank is lower than the set minimum temperature, the system will start the heating device to heat the water body to ensure that the water temperature is constantly maintained at the set drinking temperature. This control method will cause the water body in the water tank to be continuously reheated to form thousand-boiled water (thousand-boiled water, water boiled for a long time or multiple times), resulting in the deterioration of water quality, which in turn affects drinking health and taste, and the water body is easily scaled after being boiled multiple times; in addition, when the amount of water in the water tank is insufficient, users often directly add unboiled raw water to the water tank, and the raw water is mixed with the original boiled water in the water tank to form yin-yang water. If users drink the unboiled yin-yang water for a long time, it will also affect their health; that is, traditional water dispensers have drinking health problems;

[0005] ③ Traditional water dispensers need to set up multiple sections of water pipes to realize the transmission of the internal water body. When multiple water pipes are involved, it is easy to make mistakes during assembly (such as misconnecting or missing water pipes), and it will lead to difficult assembly, cumbersome assembly operations; in addition, most of the water pipes are rubber pipes that are prone to aging. After aging, the water pipes are prone to leakage, which will directly shorten the service life of the water dispenser and increase the risk of electric leakage; in addition, there is often accumulated water in the water pipes, and this accumulated water is prone to breed bacteria and affect the health of users; that is, traditional water dispensers have disadvantages such as troublesome assembly, low assembly efficiency, easy assembly errors, short service life, low safety factor, and poor hygiene;

[0006] ④ The transmission power of the water body in the water pipe generally comes from the pump body set on the water pipe. The system controls the pump body to make the water body can be transmitted along the water path. The setting of the pump body will increase the manufacturing cost of the whole machine, and the pump body is a vulnerable part, resulting in a shortened service life of the water dispenser.

[0007] Therefore, it is necessary to further improve the traditional water dispenser. Summary of the Invention

[0008] The object of the present invention is to overcome the deficiencies of the above-mentioned prior art, and to provide a thick-film instant heating water dispenser, which has the characteristics of simple and reasonable structure, low manufacturing cost, low energy consumption, quantitative water output, health and hygiene, etc.

[0009] The object of the present invention is achieved as follows:

[0010] A thick-film instant heating water dispenser includes a water storage tank and a heating container arranged from top to bottom; the water storage tank supplies water to the heating container quantitatively through a water supply device; a heating device for heating the water body in the inner cavity of the heating container and a water outlet device for discharging the water body in the inner cavity of the heating container are arranged on the heating container; the heating device is connected to a control module; a water receiving area is provided below the heating container, and the water outlet device corresponds to the water receiving area.

[0011] The water supply device includes a water supply waterway for transmitting water and a pressure relief air path for admitting air and relieving pressure; the water inlet end of the water supply waterway communicates with the inner cavity of the water storage tank, and the water outlet end corresponds to the heating container; the air inlet end of the pressure relief air path communicates with the atmospheric pressure, and the air outlet end communicates with the inner cavity of the water storage tank.

[0012] The water supply device further includes a waterway switch for conducting or blocking the water supply waterway and / or an air path switch for conducting or blocking the pressure relief air path; the waterway switch is arranged on the water supply waterway; the air path switch is arranged on the pressure relief air path; alternatively, the water supply device further includes a composite switch for simultaneously conducting or blocking the water supply waterway and the pressure relief air path; the composite switch is arranged on the water supply waterway and the pressure relief air path.

[0013] The waterway switch and / or the air path switch or the composite switch is manually controlled or electrically controlled, and the electrically controlled switch is connected to the control module.

[0014] The air inlet end of the pressure relief air path extends into the inner cavity of the heating container, and when the water level in the heating container reaches the highest level, the water body submerges the air inlet end of the pressure relief air path.

[0015] The heating device is a thick-film heater attached to the outer side wall of the heating container; the inner cavity of the heating container is an open setting; the volume of the heating container is 100 ml - 300 ml, preferably 150 ml - 250 ml.

[0016] The water outlet device includes a water outlet waterway for transmitting water and a water outlet switch for conducting or blocking the water outlet waterway; the water inlet end of the water outlet waterway communicates with the inner cavity of the heating container, and the water outlet end is located above the water receiving area; the water outlet switch is arranged on the water outlet waterway, and the water outlet switch is connected to the control module.

[0017] The water outlet switch is manually controlled or electrically controlled, and the electrically controlled water outlet switch is connected to the control module.

[0018] This water dispenser further includes a supporting base; an upper frame and a lower frame corresponding to each other up and down are arranged on the supporting base, a water storage tank and a heating container are respectively arranged on the upper frame, a window corresponding to the heating container is arranged on the upper frame, and a water receiving area is located between the upper frame and the lower frame.

[0019] The water in the water storage tank and / or the water in the heating container flows out by gravity.

[0020] The beneficial effects of the present invention are as follows:

[0021] ① By arranging a heating container to store a fixed amount of water, the heating device heats the water in the heating container separately. Since the amount of water to be heated in the heating container is small, the heating speed is fast, the energy consumption is low, the load of the heating device is light, and the service life of the heating device is long; in addition, the user can add water to the heating device quantitatively according to actual needs. After meeting the needs, since the water in the heating container will be emptied and drunk after heating, the water will not be reheated repeatedly, effectively preventing the formation of thousand-rolled water and reducing the generation of water scale; when replenishing water, the user can directly add water to the water tank. Since the water in the water tank is raw water that has not been boiled, yin-yang water will not be formed, or the full water tank can be directly replaced, and yin-yang water will not be formed either, effectively ensuring the drinking health of users;

[0022] ② The water in each water circuit of this water dispenser will be emptied, avoiding water accumulation, and thus effectively preventing the growth of bacteria, further ensuring the drinking health of users; the many and long water pipes in the traditional water dispenser are cancelled, greatly simplifying the assembly difficulty of the water dispenser, improving the assembly efficiency and quality, and effectively preventing the leakage phenomenon caused by the aging of the water pipes, ensuring the service life of the water dispenser and improving the use safety of the water dispenser;

[0023] ③ The water in the water storage tank and the water in the heating container are both automatically discharged under the action of gravity, so the setting of the pump body can be cancelled. On the one hand, this can reduce the manufacturing cost, on the other hand, it can further ensure the service life of the water dispenser, on the other hand, it can simplify the control program of the control module, and can also reduce the power consumption of the water dispenser to a certain extent; the water storage tank and the heating container are arranged in an up-and-down arrangement, which can reduce the horizontal space occupied by the water dispenser, reduce the space requirements for the use place, and is suitable for most families;

[0024] ④ The air inlet end of the pressure relief air circuit for pressure relief extends into the inner cavity of the heating container. When for some reason (such as the switch is damaged and fails), the water level in the inner cavity of the heating container reaches the set highest water level, the water will submerge the air inlet end of the pressure relief air circuit. At this time, since the pressure relief air circuit is blocked by the water, the inner cavity of the water storage tank cannot complete the air intake and pressure relief action, and the water in the water storage tank cannot be discharged through the water supply water circuit under the action of the atmospheric pressure, thereby effectively preventing the heating container from overflowing with water.

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] First embodiment

[0032] Refer to Figures 1 - 3 , the thick-film instant-heating water dispenser involved in this embodiment includes a water storage tank 1 and a heating container 3 arranged from top to bottom; the bottom of the water storage tank 1 supplies water to the heating container 3 quantitatively through a water supply device 2, and the water supply method of the water storage tank 1 is gravity drainage; a heating device 4 for heating the water body in the inner cavity of the heating container 3 and a water outlet device 5 for discharging the water body in the inner cavity of the heating container 3 are arranged on the heating container 3, and the water supply method of the heating container 3 is gravity drainage; the heating device 4 is connected to a control module 6 to enable the control module 6 to effectively control the heating device 4; below the heating container 3 is a water receiving area 9, and the water outlet device 5 corresponds to the water receiving area 9, and the user can place a water receiving container 10 (such as a water cup, etc.) on the water receiving area 9 to receive water. When in use, the user controls the water storage tank 1 to add water to the heating container 3 quantitatively through the water supply device 2 (the amount of water depends on the user's needs), and after the water addition operation is completed, the system starts the heating device 4 to heat the water body in the heating container 3. After the water body is heated to boiling, the heating device 4 stops working, and the user then drains the boiling water in the heating container 3 through the water outlet device 5, and the boiling water falls freely into the water receiving container 10.

[0033] Further, the water supply device 2 includes a water supply waterway 201 for transmitting water bodies and a pressure relief air path 202 for intake air and pressure relief; the water inlet end of the water supply waterway 201 communicates with the inner cavity of the water storage tank 1, and the water outlet end corresponds to the heating container 3; the air inlet end of the pressure relief air path 202 communicates with the atmospheric pressure, and the air outlet end communicates with the inner cavity of the water storage tank 1. The water body in the water storage tank 1 is transmitted through the water supply waterway 201 and finally falls into the heating container 3. The water supply waterway 201 involved in this embodiment is vertically arranged; the outside air is transmitted through the pressure relief air path 202 and finally enters the inner cavity of the water storage tank 1 to ensure that the water body in the water storage tank 1 can be discharged smoothly. The pressure relief air path 202 involved in this embodiment is vertically arranged.

[0034] Further, the water supply device 2 further includes a composite switch 203 for simultaneously conducting or blocking the water supply waterway 201 and the pressure relief air path 202; the composite switch 203 is arranged on the water supply waterway 201 and the pressure relief air path 202; the composite switch 203 can effectively control the on-off of the water supply waterway 201 and the pressure relief air path 202, and further control the water addition, with reliable performance and convenient and simple operation. In addition, the following scheme can also be adopted for the on-off of the waterway and the air path, that is, the water supply device 2 further includes a waterway switch for conducting or blocking the water supply waterway 201 and / or an air path switch for conducting or blocking the pressure relief air path 202; the waterway switch is arranged on the water supply waterway 201; the air path switch is arranged on the pressure relief air path 202; when the waterway switch and the air path switch are set at the same time, the two switches work without interference, and whether the waterway switch blocks the water supply waterway 201 or the air path switch blocks the pressure relief air path 202, the effect of stopping water addition can be achieved; when the waterway switch or the air path switch is set alone, whether the waterway switch blocks the water supply waterway 201 or the air path switch blocks the pressure relief air path 202, the effect of stopping water addition can be achieved.

[0035] Further, the waterway switch and / or the air path switch or the composite switch 203 is manually controlled or electrically controlled, and the electrically controlled switch is connected to the control module 6. Common electrically controlled switches include solenoid valves and the like.

[0036] Further, referring to Figure 2 Figure, the air inlet end of the pressure relief air path 202 extends into the inner cavity of the heating container 3; referring to Figure 3, when the water level in the heating container 3 reaches the highest level, the water body submerges the intake end of the pressure relief air path 202. In the case where the water supply water path 201 and the pressure relief air path 202 are constantly connected due to the damage of the water path switch and / or the air path switch or the combined switch 203, water leakage will occur in the water supply water path 201. The heating container 3 catches the leaked water body. When the water level in the heating container 3 reaches the highest water level (generally the plane where the intake end of the pressure relief air path 202 is located), the water body will block the intake end of the pressure relief air path 202 along the trend. In the case where no gas enters the inner cavity of the water storage tank 1, the atmospheric pressure can effectively prevent the water body from continuing to leak, and at the same time, it can effectively prevent the heating container 3 from overflowing; the water supply water path 201 and the pressure relief air path 202 involved in this embodiment are arranged side by side with each other.

[0037] Further, the heating device 4 is a thick film heater attached to the outer side wall of the heating container 3. The thick film heater has high heating efficiency and low energy consumption, meeting the heating requirements of this water dispenser; the inner cavity of the heating container 3 is an open type, that is, the top of the heating container 3 is open or there are openings at the top, avoiding the influence of atmospheric pressure on normal water discharge; the volume of the heating container 3 is 200 ml. Of course, the volume of the heating container 3 can be changed adaptively according to the actual needs of users or the water dispenser.

[0038] Further, the water outlet device 5 includes a water outlet water path 501 for transmitting the water body and a water outlet switch 502 for conducting or blocking the water outlet water path 501; the intake end of the water outlet water path 501 is communicated with the inner cavity of the heating container 3, and the outlet end is located above the water receiving area 9; the water outlet switch 502 is arranged on the water outlet water path 501, and the water outlet switch 502 is connected to the control module 6. The user can discharge the boiled water in the heating container 3 by opening the water outlet switch 502. The boiled water is transmitted through the water outlet water path 501 and finally falls freely into the water receiving container 10. The water outlet water path 501 involved in this embodiment is arranged vertically.

[0039] Further, the water outlet switch 502 is manually controlled or electrically controlled. The electrically controlled water outlet switch 502 is connected to the control module 6. Commonly used electric switches include solenoid valves and the like.

[0040] Further, a temperature controller 8 for monitoring the temperature of the heating device 4 is arranged on the outer side wall of the heating device 4. The temperature controller 8 is connected to the control module 6; by monitoring the surface temperature of the heating device 4, the temperature of the water body in the heating container 3 can be determined to monitor whether the water body is boiling; this temperature monitoring method has a rapid response and high sensitivity.

[0041] Furthermore, this water dispenser further includes a support base 7; on the support base 7, there are an upper frame 701 and a lower frame 703 which are arranged corresponding to each other up and down; the water storage tank 1, the heating container 3, the control module 6, etc. are respectively arranged on the upper frame 701, wherein the water storage tank 1 is detachably arranged so that users can replace the water storage tank 1 or add water to the water storage tank 1; on the upper frame 701, there is a window 702 corresponding to the heating container 3 so that users can observe the water volume in the heating container 3 (the heating container 3 is preferably made of a transparent material, such as glass, etc.) through the window 702; the water receiving area 9 is located between the upper frame 701 and the lower frame 703; the lateral area of this support base 7 is small and it occupies less space, which is suitable for most ordinary families.

[0042] Second Embodiment

[0043] See Figure 4 and Figure 5 , the difference between the water dispenser involved in this embodiment and the first embodiment is that: the pressure relief air path 202 is sleeved outside the water supply water path 201 (alternatively, the water supply water path 201 is sleeved outside the pressure relief air path 202).

[0044] For the parts not described above, they are the same as those in the first embodiment and will not be analyzed and described in detail here.
