Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more particularly to a heating tank for a water dispenser. Background Technology

[0002] The heating tank is an important component of a water dispenser. It is used to heat and store drinking water, thus providing hot water when users need it. The heating tank of a water dispenser is usually in the form of a barrel, with an internal cavity for holding the drinking water. At the bottom is a water inlet that communicates with the cavity, connected to an inlet pipe. At the top is a water outlet that also communicates with the cavity, connected to an outlet pipe.

[0003] In the aforementioned hot water tank structure, when a user takes hot water, after the hot water flows out of the outlet into the inner cavity, cold water needs to enter from the inlet to replenish the water stored inside. However, because the cold water is at a lower temperature, it mixes with the hot water in the inner cavity, causing the temperature of the already heated water to drop, resulting in the water dispenser not being able to provide the user with enough hot water. Therefore, the existing hot water tank structure needs improvement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a hot water tank that can avoid direct mixing with hot water in the inner cavity when cold water enters the inner cavity from the inlet, in light of the above-mentioned existing technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: The hot water tank includes a tank body, the tank body having an inner cavity for holding drinking water, the lower part of the tank body having a water inlet communicating with the inner cavity, the water inlet being connected to a water inlet pipe, characterized in that: the lower part of the tank body is also provided with a blocking and guiding mechanism, the blocking and guiding mechanism being arranged adjacent to the water inlet, the blocking and guiding mechanism including a blocking wall for preventing cold water entering from the water inlet from directly mixing with hot water in the inner cavity, and a guiding wall connected to the blocking wall for guiding drinking water to the periphery of the inner cavity, and a gap for water flow between the blocking and guiding mechanism and the side wall of the tank body.

[0006] To enable the hot water tank to heat drinking water, preferably, heating pipes for heating water are distributed on the side wall of the tank. These heating pipes heat the drinking water flowing in through the inlet. Combined with the aforementioned blocking and guiding mechanism, as the drinking water is guided outwards from the guiding wall, the heating pipes fully heat the drinking water before it flows upwards through the gaps to mix with the existing hot water in the tank. Simultaneously, the heating pipes on the side wall continuously heat the drinking water to a preset temperature, thus preventing a sudden drop in water temperature caused by direct mixing of hot and cold water.

[0007] As a type of blocking and guiding mechanism, preferably, the water inlet is located on the side wall of the tank, the lower end of the guiding wall is connected to the bottom wall of the tank, and the upper end is bent outward to form a blocking wall. A channel is formed between the guiding wall and the side wall of the tank to guide water to the perimeter of the inner cavity. The blocking wall is located above the water inlet and forms a gap with the side wall of the tank. The water inlet, the channel, and the gap are in fluid communication. In this way, after drinking water enters from the water inlet, it flows outward along the channel due to being blocked by the blocking wall above, and is fully heated by the heating pipe. Then, it flows upward through the gap to mix with the existing hot water above.

[0008] Furthermore, the barrier wall extends downwards from the inside out;

[0009] Alternatively, the barrier wall extends horizontally from the inside out;

[0010] Alternatively, the barrier wall extends upwards from the inside out.

[0011] Preferably, the gap gradually increases in size from the proximal end near the inlet to the distal end far from the outlet. This ensures that drinking water entering the inner cavity from the inlet can only move along the guide wall towards the distal end, further preventing the drinking water entering from the inlet from flowing directly upwards through the gap and mixing with the existing hot water in the inner cavity. Of course, the gap can also be evenly distributed from the proximal end near the inlet to the distal end far from the outlet.

[0012] As another structure of the blocking and guiding mechanism, preferably, the water inlet is located on the bottom wall of the tank, the water inlet pipe extends through the water inlet into the inner cavity, the blocking wall covers the outlet end of the water inlet pipe, the pipe wall of the water inlet pipe has at least two outlet holes communicating with the inner cavity, the outlet holes are located adjacent to the outlet end, the outer edge of the blocking wall extends outward to form the guiding wall, and the gap is formed between the guiding wall and the side wall of the tank. In this way, the blocking wall blocks the outlet end of the water inlet pipe, while the water flows out laterally from the outlet holes in the pipe wall, and is guided by the guiding wall to be heated by the heating pipes on the side wall of the tank and then flows upward from the gap to mix with the original hot water in the inner cavity.

[0013] Furthermore, the guide wall extends downwards from the inside out. This downward-extending guide wall directs the incoming drinking water downwards, preventing it from flowing directly upwards and mixing with the hot water above.

[0014] Compared with existing technologies, the advantages of this invention are as follows: The hot water tank is equipped with a blocking and guiding mechanism near the inlet, which includes a blocking wall and a guiding wall. The blocking wall prevents cold water entering through the inlet from directly mixing with the existing hot water in the inner cavity. The guiding wall guides the drinking water to the periphery of the inner cavity, where it is heated by heating pipes on the side wall of the tank. The heated drinking water then flows upward through the gap between the blocking and guiding mechanism and the side wall of the tank, mixing with the existing hot water in the inner cavity. This blocking and guiding mechanism prevents the cold water entering the inner cavity from directly mixing with the existing hot water, thus avoiding a drop in the hot water temperature and ensuring a stable output of hot water.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] like Figure 1-2 The image shows an embodiment of this utility model. This embodiment of the hot water tank includes a tank body 1, with an inner cavity 2 for holding drinking water. The lower part of the tank body 1 has a water inlet communicating with the inner cavity 2, and the upper part of the tank body 1 has a water outlet communicating with the inner cavity 2. An inlet pipe 3 is connected to the inlet, and an outlet pipe 4 is connected to the outlet. Heating pipes for heating water are distributed on the side wall 1a of the tank body 1. In use, cold water enters the inner cavity 2 through the inlet, is heated to a preset temperature by the heating pipes, and then flows out from the upper outlet to provide hot water to the user.

[0024] To prevent cold water from directly mixing with the hot water in the inner cavity 2 when it enters, thus lowering the water temperature and failing to provide enough hot water for the user, this embodiment has made special improvements to the hot water tank. Specifically, this embodiment has a blocking and guiding mechanism 5 provided at the lower part of the tank body 1. The blocking and guiding mechanism 5 is located near the water inlet. The blocking and guiding mechanism 5 can block the cold water entering through the water inlet, preventing it from directly mixing with the existing hot water in the inner cavity 2, and can guide the cold water to the sides of the tank body 1 so that the cold water is heated by the heating pipes on the side wall 1a.

[0025] See Figure 2 In this embodiment, the water inlet is located on the side wall 1a of the tank 1. The blocking and guiding mechanism 5 includes a blocking wall 51 for preventing cold water entering through the water inlet from directly mixing with hot water in the inner cavity 2, and a guiding wall 52 connected to the blocking wall 51 for guiding drinking water to the periphery of the inner cavity 2. The guiding wall 52 is arranged parallel to the side wall 1a of the tank 1, and a channel 7 is formed between the guiding wall 52 and the side wall 1a of the tank 1 to guide water to the periphery of the inner cavity 2. The lower end 52a of the guiding wall 52 is connected to the bottom wall 1b of the tank 1. The blocking wall 51 is located above the water inlet and is formed by bending outward from the upper end 52b of the guiding wall 52. In this embodiment, the blocking wall 51 extends horizontally from the inside to the outside, and its outermost end forms a gap 6 between it and the side wall 1a of the tank 1 for water to flow through. The gap 6 is evenly distributed from the proximal end near the water inlet to the distal end far from the water outlet. The water inlet, the channel 7 and the gap 6 are in fluid communication. When cold water enters through the inlet, it is blocked by the upper baffle wall 51 and flows outwards along the channel 7. As it flows outwards, the cold water is heated by the heating pipe, so that when it flows out through the gap 6 and mixes with the existing hot water above, it already has a higher water temperature and will not cause the hot water temperature in the inner cavity 2 to drop suddenly. This allows the hot water in the upper layer to maintain a preset temperature. When the newly entered drinking water flows upwards to the outlet, it can be continuously heated to a preset temperature by the heating pipe on the side wall 1a, thus stably providing users with enough hot water.

[0026] Example 2

[0027] See Figure 3 The structure of the hot water tank in this embodiment is basically the same as that in embodiment 1. The only difference is that the baffle wall 51 in this embodiment extends downward from the inside out. This has the following advantages: the downward-extending baffle wall 51 can guide the cold water entering from the inlet downward, further avoiding the possibility of the newly entered cold water flowing upward and directly mixing with the hot water above, thereby stabilizing the output of hot water.

[0028] Example 3

[0029] See Figure 4The structure of the hot water tank in this embodiment is basically the same as that in embodiment 1, except that the baffle wall 51 in this embodiment extends upward from the inside out. This upwardly extending baffle wall 51 can block the cold water that just enters from the inlet, preventing it from flowing directly upward and mixing with the hot water above, thus causing a sudden drop in the temperature of the hot water in the inner cavity 2, thereby stabilizing the output of hot water.

[0030] Example 4

[0031] See Figure 5 The structure of the hot water tank in this embodiment is basically the same as that in Embodiment 1, except that the gap 6 between the outer end of the baffle wall 51 and the side wall 1a of the tank body 1 gradually increases from the near end near the inlet to the far end far from the outlet. This has the following advantages: after drinking water enters the inner cavity 2 from the inlet, it can only move along the guide wall 52 to the far end. After being heated by the heating pipe, it flows upward from the gap 6 at the far end and mixes with the existing hot water above. This avoids the cold water that just entered from the inlet flowing directly upward from the gap 6 and mixing with the hot water above, thus lowering the hot water temperature and stabilizing the output of hot water.

[0032] Example 5

[0033] See Figure 6 The structure of the hot water tank in this embodiment is basically the same as that in Embodiment 1, except that: the water inlet is located on the bottom wall 1b of the tank body 1, the water inlet pipe 3 passes through the water inlet and extends into the inner cavity 2, and the blocking and guiding mechanism 5 includes a blocking wall 51 for preventing the cold water entering through the water inlet from directly mixing with the hot water in the inner cavity 2, and a guiding wall 52 connected to the blocking wall 51 for guiding drinking water to the periphery of the inner cavity 2. The blocking wall 51 covers the water outlet end of the water inlet pipe 3. Since the water outlet end of the water inlet pipe 3 is closed by the blocking wall 51, the water inlet pipe 3 in this embodiment has multiple water outlet holes 31 distributed circumferentially on the pipe wall near the water outlet end, and water can enter the inner cavity 2 through the water outlet holes 31. The outer edge of the barrier wall 51 extends outward to form a guide wall 52. There is a gap 6 between the guide wall 52 and the side wall 1a of the tank body 1. The guide wall 52 extends downward from the inside out, which can guide the newly entered cold water to the surrounding areas and downward at the same time, preventing it from flowing upward and directly mixing with the hot water above, thereby stabilizing the output of hot water.
