Description

Technical Field

[0001] The utility model relates to a hot water generator, in particular to a direct-heating temperature-controllable hot water generator. Background Art

[0002] Hot water generator is a mechanical device that uses the heat energy of fuel or other energy to heat water into steam and heats water through steam. Hot water generator has a wide range of applications, and is widely used in garment factories, dry cleaners, restaurants, steamed bun shops, canteens, restaurants, factories, mines, bean products factories and other places.

[0003] Chinese patent CN111076566A discloses a hot water generator which has the following defects: (1) although the partition can reduce the flow rate of steam and cold water, the flow path is too long, resulting in a temperature difference between the upper and lower parts, making the outlet water temperature very unstable; (2) the hot water outlet is set at the top. When the water temperature is too high, the overheated water needs to be discharged before cold water can be added to cool it down. This is very unreasonable and cannot cool it down stably and quickly. Therefore, its temperature control is very poor. Utility Model Content

[0023] The following specific embodiments illustrate the implementation of the present invention, and those familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0024] See also Figure 1 The utility model provides a directly heated controllable temperature hot water generator, comprising a storage tank 1, wherein a first partition 2 is vertically arranged in the storage tank 1, and the first partition 2 divides the space in the storage tank 1 into a heating chamber 100 and a buffer chamber 200; a plurality of second partitions 3 are vertically arranged in the buffer chamber 200, and through holes are provided on the first partition 2 and the second partition 3; a cold water inlet 11 is provided at the upper part of the storage tank 1 and at one side of the buffer chamber 200; a coil 4 is provided in the heating chamber 100, steam is introduced into the coil 4, and a plurality of air outlets are provided on the coil 4; a hot water outlet 12 is provided at the lower part of the storage tank 1 and at one side of the heating chamber 100.

[0025] The utility model divides the space in the storage tank 1 into a heating chamber 100 and a buffer chamber 200 through a first partition 2. The buffer chamber 200 can pre-store cold water, so that the cold water gradually enters the heating chamber 100 through the through hole of the first partition 2 and mixes evenly with the steam, so that the temperature of the hot water can be stably adjusted, and the sudden temperature drop caused by the cold water directly entering the heating chamber 100 is avoided. In addition, the utility model also sets a plurality of second partitions 3 in the buffer chamber 200 to achieve multiple buffering of the cold water entering the heating chamber 100, and ensure the stability of the water temperature in the heating chamber 100.

[0026] Furthermore, the bottoms of the first partition plate 2 and the second partition plate 3 are connected to the storage tank 1 , and a gap is left between the tops of the first partition plate 2 and the second partition plate 3 and the storage tank 1 .

[0027] Furthermore, the height of the first partition plate 2 is higher than the height of the second partition plate 3 .

[0028] Furthermore, two second partitions 3 are spaced apart in the buffer cavity 200 .

[0029] Furthermore, along the height direction of the first partition 2 / the second partition 3, the distribution density of the through holes is getting smaller and smaller. The density of the through holes is getting smaller and smaller, which means that the through holes are distributed less and less, and the area of ​​the through holes is getting smaller and smaller.

[0030] The utility model arranges the through hole distribution density to become smaller from bottom to top, mainly to ensure that most of the water is heated in the lower part of the heating chamber 100, to avoid the water level in the heating chamber 100 being too high, resulting in insufficient heating of the water in the upper part and causing temperature difference.

[0031] Furthermore, along the height direction of the first partition plate 2 / the second partition plate 3 , the area of ​​a single through hole becomes smaller and smaller.

[0032] Furthermore, along the height direction of the first partition plate 2 / the second partition plate 3 , the spacing between each row of through holes becomes larger and larger.

[0033] In one embodiment of the utility model, the coil 4 is bent, and the coil 4 is arranged between the inner wall of the storage tank 1 and the first partition 2. The storage tank 1 is provided with a steam inlet 13 connected to the coil 4, and a valve for controlling the amount of steam is provided at the steam inlet 13. By providing the bent coil 4, sufficient steam can be ensured to fully heat the water in the heating chamber 100.

[0034] Furthermore, the height of the coil 4 is located below the middle of the storage tank 1 .

[0035] Furthermore, a temperature sensor is provided in the storage tank 1, and the temperature sensor is used to control the amount of steam and the amount of cold water entering. When in use, the temperature sensor can monitor the temperature of the hot water in the storage tank 1 at any time. When the temperature of the hot water in the storage tank 1 does not meet the working condition requirements, the amount of steam entering and exiting can be controlled by controlling the opening and closing degree of the valve at the steam inlet 13, thereby controlling the temperature of the hot water; the temperature of the hot water can also be adjusted by controlling the amount of cold water added to the cold water inlet 11 at the top.

[0036] In one embodiment of the utility model, the top of the storage tank 1 is provided with an opening communicating with the outside, and an upper cover 5 is provided at the opening. The upper cover 5 is provided to facilitate later repair and maintenance.

[0037] In one embodiment of the utility model, an exhaust pipe 15 is provided on the top of the storage tank 1. The exhaust pipe 15 is a curved pipe with its opening facing downward. By providing the exhaust pipe 15, excessive pressure inside the storage tank 1 can be avoided, thereby ensuring the safety of the hot water generator.

[0038] In one embodiment of the present invention, a sewage outlet 14 is further provided at the bottom of the storage tank 1 to facilitate cleaning of the storage tank 1 .

[0039] The utility model has a simple structure. The buffer chamber is formed by the first partition, so that the cold water gradually enters the heating chamber through the through hole of the first partition and mixes with the steam evenly, avoiding the sudden change of water temperature caused by the cold water directly entering the heating chamber, so that the hot water temperature can be stably adjusted; and the through hole distribution density on the first partition / second partition is set to be smaller and smaller from bottom to top, ensuring that most of the water is heated in the lower part of the heating chamber, avoiding the water level in the heating chamber being too high, resulting in insufficient heating of the upper water, causing temperature difference. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
