Description

Technical Field

[0001] The present application relates to the field of drinking water equipment, and particularly to a dual-tank direct drinking machine. Background Art

[0002] With the improvement of living conditions, more and more people begin to pay attention to the improvement of living quality. As an important household appliance for improving living quality, a direct drinking machine filters harmful substances (such as heavy metals, residual chlorine, bacteria, and viruses) in municipal tap water by using a filter element, so that the water can meet the direct drinking standard. At the same time, the direct drinking machine also has a heating function. By using a heating box arranged in the machine body and heating the water through a heating tube placed in the heating box, people can take cold water and hot water at any time to meet the drinking water needs.

[0003] However, as the use time of the direct drinking machine increases, scale will be generated in the heating box, and the heating tube is more likely to generate scale due to higher temperature. If the scale on the heating tube is not cleaned in time, it will reduce the heating efficiency, increase the energy consumption of the heating tube, and affect the service life of the heating tube.

[0004] At present, the common method for cleaning the scale on the heating tube of a direct drinking machine is to disassemble the whole heating box and clean the internal scale. Although this method can directly contact and remove the scale, the operation is complex and time-consuming, increasing the maintenance cost of users; or use a descaling agent for cleaning. This method is relatively convenient, but since a large amount of clean water is required to flush the descaling agent remaining in the water tank to completely remove it, it causes waste of water resources. Summary of the Invention

[0005] In order to reduce the scale attached to the heating tube of the direct drinking machine and improve the service life of the heating tube, the present application provides a dual-tank direct drinking machine.

[0006] The dual-tank direct drinking machine provided by the present application adopts the following technical solutions: A dual-tank direct drinking machine includes a water outlet tank and a filter element. The water outlet tank includes a box body and a support seat slidably connected to the box body. A heating tube is connected to the support seat, and the heating tube can be moved into or out of the box body through the support seat; The filter element is used for filtering municipal tap water; the filter element is communicated with the water outlet tank.

[0007] By adopting the above technical solutions, the heating tube is slidably connected to the box body by using the support seat, so that the heating tube can be moved out of the box body for scale cleaning, reducing the workload of the overall disassembly and assembly method and reducing the waste of water resources.

[0008] Optionally, a film roller is rotatably connected to the outside of the box body. A storage film is arranged on the film roller, and the storage film is used for storing the scale cleaned from the heating tube. A clamping member is arranged on the support seat, and the clamping member is connected to one end of the storage film. The clamping member is used for unfolding the storage film so that the storage film stores the scale cleaned from the heating tube.

[0009] By adopting the above technical solution, after the clamping member clamps one end of the storage film, the clamping member moves along with the support seat to unfold the storage film, thereby facilitating the collection of the scale dropped during the cleaning process of the heating tube. The storage film provides a convenient collection method for scale cleaning, reduces the cleaning workload after the scale drops, and improves the cleaning efficiency.

[0010] Optionally, a storage hole is arranged on the support seat, and the storage film passes through the storage hole and is connected to the clamping member.

[0011] By adopting the above technical solution, after the scale cleaning is completed, when the support seat moves the heating tube into the box body, the storage film can pass through the storage hole and take out the scale, which is convenient for cleaning and improves the cleaning efficiency.

[0012] Optionally, an arc surface is arranged at the lower part of the storage hole, and a guiding surface is arranged on the inner side wall of the storage hole. The storage hole makes the storage film concave through the arc surface and the guiding surface.

[0013] By adopting the above technical solution, when the storage film passes through, the arc surface and the guiding surface make the storage film in a concave state, which is convenient for better storing the scale, reduces the possibility of the scale falling out of the storage film, and improves the cleaning efficiency.

[0014] Optionally, a film cutting member is arranged on the support seat on the side close to the clamping member, and the film cutting member is used for cutting the storage film.

[0015] By adopting the above technical solution, the film cutting member can conveniently cut the storage film storing the scale, reduces the excessive use of the storage film, and improves the overall convenience and practicality of the device.

[0016] Optionally, a placement groove is connected to the support seat on the side close to the clamping member, and the clamping member is placed in the placement groove.

[0017] By adopting the above technical solution, the placement groove fixes the clamping member, enables the clamping member to move along with the support seat, and pulls one end of the storage film, improving the convenience of device operation. At the same time, the placement groove can store the clamping member when it is not in use, reducing the possibility of the clamping member being lost or damaged due to random placement.

[0018] Optionally, a leak-proof block is provided on the support seat, and a sealing ring is provided on the support seat around the leak-proof block. The leak-proof block and the sealing ring are used to seal the connection between the box body and the support seat.

[0020] Optionally, a locking member is provided on the support seat, and the locking member is used to lock the support seat and the box body.

[0021] By adopting the above technical solution, the locking member reliably locks the support seat and the box body, reducing the possibility of relative movement between the support seat and the box body, which may cause water leakage from the connection.

[0022] Optionally, a slider is provided on the support seat, and a sliding groove is provided on the box body. The slider is slidably connected to the sliding groove.

[0023] By adopting the above technical solution, the support seat and the box body are stably and reliably slidably connected, reducing the possibility of the support seat shifting during movement.

[0024] Optionally, a preheating tank is further included. The preheating tank is used to preheat the water filtered by the filter element; the filter element, the preheating tank and the water outlet tank are communicated in sequence.

[0025] By adopting the above technical solution, the preheating tank can preheat the water filtered by the filter element, reducing the working load of the heating tube in the water outlet tank, improving the overall heating efficiency and increasing the service life of the heating tube.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By using the support seat and the box body to be slidably connected through the heating tube, the heating tube can be removed from the box body for scale cleaning, reducing the workload of the overall disassembly and assembly method and reducing the waste of water resources; 2.

Detailed Description of the Embodiment

[0029] The following will Figure 1 - be Figure 7 further described in detail with reference to the accompanying

[0030] The embodiment of the present application discloses a dual-tank direct drinking machine. As Figure 1 and Figure 2 shown, the dual-tank direct drinking machine includes a filter element 9, a preheating tank 2 and a water outlet tank 1. After the municipal tap water is filtered by the filter element 9, it enters the preheating tank 2 for preheating. In the preheating tank 2, the water can be heated to a certain temperature. In this embodiment, the water can be heated to 45 degrees in the preheating tank 2. After being heated by the preheating tank 2, the water enters the water outlet tank 1 and is further heated to 100 degrees. The preheating tank 2 can preheat the water to a certain temperature in advance, saving the time for heating the water from room temperature to 100 degrees. When hot water is needed, the direct drinking machine can supply it quickly, reducing the waiting time.

[0031] As Figure 3As shown, the water outlet tank 1 includes a box body 101 and a support base 102. A slide rail 1021 is fixedly connected to the support base 102, and a slide groove 1011 that cooperates with the slide rail 1021 is provided on the box body 101. Through the cooperation of the slide rail 1021 and the slide groove 1011, the support base 102 and the box body 101 are stably and reliably slidably connected, reducing the possibility of the support base 102 shifting during movement. A heating tube 3 is fixedly connected to the support base 102. By utilizing the sliding between the support base 102 and the box body 101, the heating tube 3 can be moved out of the box body 101 for scale cleaning, reducing the workload of the overall disassembly and assembly method and reducing the waste of water resources.

[0032] Meanwhile, in this embodiment, with the dual-tank design of the preheating tank 2 and the water outlet tank 1, the heating tube heats water at a certain temperature to 100 degrees. Compared with heating from room temperature to 100 degrees, the working load of the heating tube in the water outlet tank 1 is reduced, the overall heating efficiency is improved, and the service life of the heating tube 3 is increased.

[0033] As Figure 3 and Figure 4 shown, a film roller 4 is fixedly connected to the box body 101, a storage film 5 is installed on the film roller 4, a placement groove 8 is fixedly connected to the side of the support base 102 away from the box body 101, and a clamping member 6 is placed in the placement groove 8. In this embodiment, the clamping member 6 is a long strip-shaped clip. After the clamping member 6 clamps one end of the storage film 5, it is placed in the placement groove 8. Since the placement groove 8 is fixedly connected to the support base 102, when the support base 102 is slid to move the heating tube 3 out of the box body 101, the clamping member 6 moves together with the support base 102 and pulls one end of the storage film 5, causing the storage film 5 to unfold. After the storage film 5 unfolds, it is convenient to collect the scale that falls during the cleaning of the heating tube 3. The storage film 5 provides a convenient collection method for scale cleaning, reduces the cleaning workload after the scale falls, and improves the cleaning efficiency. At the same time, the placement groove 8 can store the clamping member 6 when it is not in use, reducing the possibility of the clamping member 6 being randomly placed and lost or damaged.

[0034] In addition, as Figure 4 shown, a convex block 801 is fixedly connected to the placement groove 8. When the clamping member 6 is placed in the placement groove 8, the convex block 801 abuts against the clamping member 6, making the storage film 5 clamped more firmly and improving the connection stability between the clamping member 6 and the storage film 5.

[0035] As Figure 5 and Figure 6 shown, a storage hole 7 is provided on the support base 102, and the storage film 5 passes through the storage hole 7 and is clamped by the clamping member 6. Among them, an arc surface 701 is provided at the lower part of the storage hole 7, and a guiding surface 702 is provided on the inner side wall of the storage hole 7.

[0036] It should be noted that after the scale on the heating tube 3 is cleaned, the scale falls on the storage film 5 and is collected. At this time, the clamping member 6 is taken out from the placement groove 8, and the position of the clamping member 6 is kept unchanged. The support seat 102 is moved to make the heating tube 3 return to the box body 101. During the process of the heating tube 3 returning to the box body 101, the storage film 5 collecting the scale passes through the storage hole 7, so that the scale moves to the side of the support seat 102 away from the box body 101, which is convenient for cleaning, thus improving the cleaning efficiency. When the storage film 5 passes through the storage hole 7, the arc surface 701 enables the storage film 5 to maintain a state of sagging in the middle under the action of the gravity of the scale; the guiding surface 702 can bend the two sides of the storage film 5 towards the middle. Through the arc surface 701 and the guiding surface 702, the storage film 5 is in a concave state, which can better store the scale, reduce the possibility of the scale falling out of the storage film 5, and improve the cleaning efficiency.

[0037] As Figure 3 and Figure 4 shown, a film cutting member 12 is also fixedly connected to the support seat 102. In this embodiment, the film cutting member 12 is a blade. After the storage film 5 moves all the scale out of the storage hole 7, the storage film 5 is abutted against the film cutting member 12, so that a part of the storage film 5 collecting the scale is cut off, which is convenient for throwing away the scale for treatment. Using the film cutting member 12 to cut the storage film 5 reduces the excessive use of the storage film 5 and improves the overall convenience and practicality of the device.

[0038] In addition, as Figure 7 shown, a leak-proof block 10 is also fixedly connected to the support seat 102, and a sealing ring 11 is fixedly connected to the periphery of the leak-proof block 10. When the support seat 102 moves to abut against the box body 101, the leak-proof block 10 and the sealing ring 11 can block the connection between the support seat 102 and the box body 101, reduce the possibility of water leakage from the connection, and improve the reliability and safety of the water outlet tank 1. As Figure 1 shown, a locking member 13 is installed on the support seat 102. In this embodiment, the locking member is a bolt; the support seat 102 is locked with the box body 101 by using the locking member 13, reducing the possibility of relative movement between the support seat 102 and the box body 101, which causes water to leak from the connection.

[0039] In addition, in this embodiment, the heating power of the heating tube 3 in the water outlet tank 1 is higher, and it is easier to generate scale compared with the heating tube 3 in the preheating tank. Therefore, the scale on the heating tube 3 in the water outlet tank 1 is removed in this embodiment. In some other embodiments, the descaling method of this embodiment can also be used for descaling the heating tube of the preheating tank.

[0040] The implementation principle of a dual-tank direct drinking machine in an embodiment of the present application is: When it is necessary to remove scale from the heating tube 3 in the water outlet tank 1, first empty the water in the water outlet tank 1, and then slide the support seat 102 to move the heating tube 3 out of the box body 101. When the support seat 102 moves, the clamping member 6 is located in the placement groove 8, so that the clamping member 6 moves together with the support seat 102. As the clamping member 6 moves, the storage film 5 unfolds under the traction of the clamping member 6. At this time, after the heating tube 3 moves to a suitable position, scale cleaning is carried out. The scale after cleaning falls into the storage film 5, which is convenient for cleaning the scale and improves the cleaning efficiency.

[0041] After the cleaning is completed, move the support seat 102 to move the heating tube back into the box body 101. At the same time, move the clamping member 6 out of the placement groove 8 and keep its position fixed. As the support seat 102 moves towards the box body 101, the storage film 5 passes through the storage hole 7 and moves the scale out. When the storage film 5 passes through the storage hole 7, the arc surface 701 and the guiding surface 702 make the storage film 5 in a concave state, better accommodating the scale in the storage film 5 and reducing the possibility of the scale falling out of the storage film 5. After all the scale has moved out of the storage hole 7, use the cutting member to cut the storage film 5. A part of the storage film 5 containing scale is discarded, and the end of the other part of the storage film 5 is clamped by the clamping member 6 and placed in the placement groove 8 for the next use.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
