Description

Technical Field

[0001] The utility model relates to the technical field of emptying direct drinking machines, in particular to a direct drinking machine with an automatically emptying water tank. Background Art

[0002] A direct drinking machine is an appliance that purifies municipal tap water into direct drinking water, and at the same time heats, cools and distributes the purified water by consuming electrical energy.

[0003] However, existing direct drinking machines generally have two pre-storage tanks, one for loading room temperature water and the other for heating water. When the water dispenser is not used for many days, the bottled pure water connected to the water dispenser is generally not removed from the water dispenser. At this time, there will always be water in the two pre-storage tanks that has not been emptied. If the water stays in the two pre-storage tanks for many days, a large number of bacteria will breed in the pre-storage tanks.

[0004] For example, an emptying device disclosed in Chinese patent publication number CN218528472U, the emptying device for the direct drinking machine presses the first touch switch to close the first solenoid valve, so that the inside of the water inlet pipe is blocked, so that the water in the bottled water cannot enter the pre-storage tank through the water inlet pipe, and opens the second solenoid valve to make the inside of the sewer pipe unobstructed, thereby allowing the water in the pre-storage tank to be discharged into the collection box through the sewer pipe. During this period, the amount of water in the pre-storage tank is observed through the second transparent plate and the first transparent plate to determine whether the water in the pre-storage tank is drained, thereby achieving the effect of emptying the water in the pre-storage tank, and avoiding as much as possible the storage of a large amount of water in the pre-storage tank and the breeding of a large number of bacteria when the direct drinking machine is not used for many days.

[0005] In the above-mentioned emptying device, the water inlet pipe connected to the water tank of the direct drinking machine needs to be separated from the water tank during the disassembly and assembly process. In the cold environment of winter, the connection between the water inlet pipe and the water tank is prone to freezing. Therefore, if the water dispenser is not used for many days, the connection between the water inlet pipe and the water tank is prone to rupture. After drainage is completed, the water inlet pipe needs to be separated from the water tank. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present invention provides a direct drinking machine with an automatically emptying water tank, which solves the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a direct drinking machine with automatic water tank emptying, comprising a direct drinking machine body, a panel opening for receiving water is opened on one side of the direct drinking machine body, a water inlet for receiving water is provided on the panel opening, the water inlet is connected to a built-in water tank for storing water through a water inlet pipe, and an emptying module is provided at the bottom of the built-in water tank;

[0008] The drain module includes a downpipe that is limit-mounted at the bottom of the built-in water tank. A drain hopper that can be threadedly connected therein is fitted at the bottom of the downpipe. A hollow connecting pipe is welded to the bottom of the drain hopper. The connecting pipe is connected with a meshing gear through a connecting key, and an external wall of the meshing gear is meshed with a toothed disc whose outer wall is welded with a bracket.

[0009] In this embodiment, the bottom of the downpipe is threadedly connected to the top of the drain hopper through a threaded groove opened inside it. This type of flange connection method enables the drain hopper to be quickly disassembled from the downpipe. Therefore, when the direct drinking machine is not used for a long time, after the water in the built-in water tank of the direct drinking machine is drained, the built-in water tank is disconnected from the drain module to avoid residual water remaining in the downpipe, the drain hopper and the connecting pipe, prevent the inside of the pipeline from freezing, and ensure the normal subsequent use of the direct drinking machine.

[0010] A further improvement of the technical solution of the present utility model is that the other end of the bracket is welded to a limit seat that is vertically and fixedly installed on a rotating base. A driving bevel gear is rotatably installed on the rotating base, and a rotating rod with sleeves rotatably installed at both ends thereof is led into the limit seat.

[0011] A further improvement of the technical solution of the present utility model is that a concave plate penetrating the middle of the bracket is welded between the two mounting sleeves. An impact head is welded to the top of the concave plate at a position directly below the connecting pipe, and a touch switch is arranged above the impact head and at the bottom of the connecting pipe. When the rotating base is driven by a driving motor, the rotating base and the limit seat thereon start to rotate. At this time, the bracket welded to the limit seat drives the toothed disc connected therein to be transmitted with the meshing gear. At this time, the drain hopper and the connecting pipe below the downpipe rotate in the downpipe. Due to the threaded connection between the downpipe and the drain hopper, the docking relationship between the downpipe and the drain hopper is cancelled, and finally the quick disconnection of the downpipe and the drain pipe is completed. Finally, the drain pipe is separated from the built-in water tank. Further, during the disassembly process, because its electric control push rod controls the height of the overall drain module, after the connecting pipe is disassembled from the downpipe as a whole, the connecting pipe and the touch switch fall into the limit area formed by the bracket and the concave plate. At this time, the touch switch collides with the impact head, turning on the electric control push rod. At this time, the electric control push rod descends to complete the taking of the connecting pipe and the drain hopper.

[0012] A further improvement of the technical solution of the present utility model is that driven bevel gears meshingly connected with the driving bevel gear are symmetrically arranged at the left and right ends of the rotating rod.

[0013] A further improvement of the technical solution of the present utility model is that the bottom of the rotating base is connected to the output end of a driving motor installed on a base through a coupling, and a plurality of electric control push rods are fixedly installed at the bottom of the base.

[0014] A further improvement of the technical solution of the present utility model lies in that drain pipes for draining water are installed at the left and right ends of the emptying hopper in a limited manner, and electromagnetic valves for controlling drainage are installed on both of the drain pipes in a limited manner, and the other ends of the drain pipes are connected to a treatment tank inside the main body of the direct drinking machine.

[0015] Beneficial effects

[0016] The present utility model provides a direct drinking machine with automatic emptying of the water tank. Compared with the prior art, it has the following beneficial effects:

[0017] 1. For the direct drinking machine with automatic emptying of the water tank, the threaded groove opened inside the downpipe is threadedly connected to the top of the emptying hopper. This flange-like connection method enables the emptying hopper to be quickly disassembled from the downpipe. After the water is emptied, the built-in water tank and the emptying module are disconnected, avoiding the remaining water remaining in the downpipe, the emptying hopper and the connecting pipe, preventing the freezing of the pipeline inside, and ensuring the normal subsequent use of the direct drinking machine.

[0018] 2. For the direct drinking machine with automatic emptying of the water tank, after the connecting pipe is disassembled from the downpipe as a whole, the connecting pipe and the touch switch fall into the limiting area formed by the bracket and the concave plate. At this time, the touch switch collides with the impact head, turning on the electric control push rod. At this time, the electric control push rod descends to complete the taking of the connecting pipe and the emptying hopper. Brief description of the drawings

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 - 4 , this utility model provides three technical solutions:

[0033] Example 1:

[0034] A direct drinking machine with an automatically emptying water tank includes a main body 100. A panel opening 100a for receiving water is provided on one side of the main body 100. A water inlet 100b for receiving water is provided on the panel opening 100a. The water inlet 100b is connected to a built-in water tank 200 for storing water through a water receiving pipe 100c. An emptying module is provided at the bottom of the built-in water tank 200.

[0035] The emptying module includes a downpipe 301 which is limitedly installed at the bottom of the built-in water tank 200. An emptying bucket 302 which can be threadedly connected to the downpipe 301 is embedded at the bottom of the downpipe 301. A hollow connecting pipe 303 is welded to the bottom of the emptying bucket 302. The connecting pipe 303 is connected to a meshing gear 304 through a connecting key. The meshing gear 304 is meshed with a toothed disc 306 of a bracket 305 welded on its outer wall.

[0036] In this embodiment, the bottom of the sewer pipe 301 is threadedly connected to the top of the emptying bucket 302 through a threaded groove opened inside it. This flange-like connection method allows the emptying bucket 302 to be quickly disassembled from the sewer pipe 301. Therefore, when the direct drinking machine is not used for a long time, after the water in the built-in water tank 200 of the direct drinking machine is drained, the built-in water tank 200 is disconnected from the emptying module to avoid residual water in the sewer pipe 301, the emptying bucket 302 and the connecting pipe 303, to avoid freezing inside the pipe, and to ensure the subsequent normal use of the direct drinking machine.

[0037] Example 2:

[0038] Based on Embodiment 1: The other end of the bracket 305 is welded to the limiting seat 307 vertically and fixedly installed on the rotating base 308. A driving bevel gear 307a is rotatably installed on the rotating base 308. A rotating rod 307c is inserted into the limiting seat 307, and rotating sleeves 307b are rotatably installed at both ends of the rotating rod 307c. A concave plate 307d passing through the middle of the bracket 305 is welded between the two sets of rotating sleeves 307b. A striking head 307d1 is welded to the top of the concave plate 307d directly below the connecting pipe 303. A touch switch 307d2 is arranged above the striking head 307d1 and at the bottom of the connecting pipe 303.

[0039] In this embodiment, when the rotating base 308 is driven by the driving motor 400a, the rotating base 308 and the limiting seat 307 thereon start to rotate. At this time, the bracket 305 welded to the limiting seat 307 drives the gear disc 306 connected therein to transmit with the meshing gear 304. At this time, the emptying hopper 302 and the connecting pipe 303 below the sewer pipe 301 rotate in the sewer pipe 301. Due to the threaded connection between the sewer pipe 301 and the emptying hopper 302, the docking relationship between the sewer pipe 301 and the emptying hopper 302 is cancelled, and finally the rapid disconnection between the sewer pipe 301 and the drain pipe 500 is completed, and finally the drain pipe 500 is separated from the built-in water tank 200.

[0040] Furthermore, during the disassembly process, since the electric control push rod 400b controls the height of the overall emptying module, after the connecting pipe 303 is completely disassembled from the sewer pipe 301, the connecting pipe 303 and the touch switch 307d2 fall into the limiting area formed by the bracket 305 and the concave plate 307d. At this time, the touch switch 307d2 collides with the striking head 307d1, turning on the electric control push rod 400b. At this time, the electric control push rod 400b descends to complete the taking of the connecting pipe 303 and the emptying hopper 302.

[0041] The premise of the above situation is that the ratchet gear 304 has sufficient thickness and still transmits with the gear disc 306 during the gradual descent of the emptying hopper 302. Furthermore, in order to ensure that the bracket 305 and the concave plate 307d can stably limit the falling emptying hopper 302 and gear disc 306, both the emptying hopper 302 and the bracket 305 are made of permanent magnet materials and attract each other after falling.

[0042] Embodiment 3:

[0043] [[ID=~15]]Based on Embodiment 1 and Embodiment 2: Driven bevel gears 307c1 meshing with the driving bevel gear 307a are symmetrically arranged at the left and right ends of the rotating rod 307c.

[0044] In this embodiment, the present utility model provides an improved solution based on the prior art. In this case, the driving bevel gear 307a and the driven bevel gear 307c1 are meshed and connected, so the rotating rod 307c rotates. In this situation, the rotating rod 307c and the sleeve 307b are changed to be rotatably connected. Therefore, the concave plate 307d connected to the sleeve 307b rotates periodically. The impact head 307d1 touches the touch switch 307d2 after rotating to the highest point. At this time, an electric control valve is additionally installed in the emptying hopper 302. Therefore, the emptying hopper 302 realizes automatic emptying. It can be seen that in this specific embodiment, the bracket 305 needs to be removed, and the disassembly and assembly of the emptying hopper 302 after emptying cannot be achieved, only automatic emptying is realized.

[0045] Embodiment 4:

[0046] Based on Embodiment 1 and Embodiment 2: The bottom of the rotating base 308 is connected by a coupling to the output end of a driving motor 400a installed on the base 400, and a plurality of electric control push rods 400b are fixedly installed at the bottom of the base 400.

[0047] The left and right ends of the emptying hopper 302 are limitedly installed with drain pipes 500 for draining water. Electric control valves 500a for controlling drainage are limitedly installed on both drain pipes 500, and the other ends of the drain pipes 500 are connected to a treatment tank 500b inside the main body 100 of the drinking machine.

[0048] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0049] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0050] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
