Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of evaporators, and particularly relates to a single-channel evaporator. Background Art
[0002] A steam iron is one of the commonly used devices for ironing clothes. At present, most ironing devices on the market have the function of steam ironing to meet people's needs for ironing clothes. Specifically, the hot steam generated by the internal evaporator continuously contacts the clothes and fabrics, so as to achieve the purpose of softening the fiber tissues of the clothes and fabrics, and the clothes and fabrics are flattened through auxiliary actions, so as to meet people's needs for ironing clothes and fabrics.
[0003] In the prior art, a heating pipe is usually adaptively installed on an evaporation box body, and high temperature is generated by the heating pipe to vaporize water, that is, steam is generated. The pressure in the evaporator increases accordingly, and then the steam will be guided into a handheld hanging iron along a preset path; in some double-heating-channel solutions, the vaporized steam is prone to shunt and gas cross-flow, resulting in uneven air outlet of the steam iron and relatively weak output steam. Moreover, due to the influence of some heating channels, the vaporization of water flow is not thorough enough, and high-temperature water droplets are easily formed inside, that is, the phenomenon of water spraying will occur, which will cause the clothes to be wet and affect the ironing effect of the clothes. Summary of the Utility Model
[0004] The utility model provides a single-channel evaporator with relatively stable vaporization effect and uniform air outlet.
[0005] To achieve the above object, the utility model adopts the following technical scheme:
[0006] A single-channel evaporator includes an evaporation box body, a heating body is adaptively installed on the evaporation box body, a vaporization flow channel is formed in the evaporation box body, and a high-temperature region is formed in the heating body; a steam outlet is arranged on the evaporation box body; the water and / or steam in the vaporization flow channel passes through the high-temperature region at least twice and then sprays out from the steam outlet.
[0007] The principle and advantages of this scheme are as follows: By reasonably arranging the vaporization flow channel, the high-temperature region formed by the heating body can be passed through at least twice on the path of the vaporization flow channel, and the high-temperature heat source can be fully absorbed and utilized preferentially. The vaporized steam is relatively in a state of volume expansion. Under the state of high temperature and high pressure, it is beneficial to the rapid flow of steam, so that the steam flow rate sprayed out from the steam outlet is relatively large, and the steam volume is also increased synchronously; by vaporizing and absorbing the heat of the high-temperature region multiple times and the steam passing through the high-temperature region, the overall evaporation box body will not have a local high-temperature situation, and the situation of partial gas liquefaction and uneven air outlet due to uneven heating will not occur, thus ensuring a reasonable temperature control effect and improving the ironing effect.
[0008] Preferably, as an improvement, an isolation rib group is provided in the evaporation box body. The isolation rib group forms a vaporization flow channel. The vaporization flow channel has a starting section, and a part of the starting section is located in the high-temperature area. The isolation rib group includes a first isolation rib and a second isolation rib. The first isolation rib and the second isolation rib form the starting section, and the bottom wall height of the starting section is higher than the bottom wall height of other areas of the vaporization flow channel.
[0009] Beneficial effects: By adopting the above technical solution, the high-temperature heat source can be preferentially absorbed and utilized. The vaporized steam is relatively in a state of volume expansion. Under the state of high temperature and high pressure, it is beneficial to the rapid flow of the steam, so that the steam velocity ejected from the steam outlet is relatively large. Based on the fact that the bottom wall height of the starting section is higher than the bottom wall height of other areas of the vaporization flow channel, during the vaporization of water, it is convenient to shorten the path length of the inlet water and quickly contact the evaporation box body to avoid the occurrence of some gas explosion phenomena.
[0010] Preferably, as an improvement, the distance between the first isolation rib and the second isolation rib gradually increases along the inner movement path of the steam.
[0011] Beneficial effects: By adopting the above technical solution, it is convenient to guide the steam during the vaporization of water.
[0012] Preferably, as an improvement, the overall shape of the heating element is M-shaped.
[0013] Preferably, as an improvement, a thermostat for controlling the temperature of the heating element is installed on the outer side wall of the evaporation box body. The thermostat is electrically connected to the heating element. The installation position of the thermostat is arranged opposite to the high-temperature area.
[0014] Beneficial effects: By adopting the above technical solution, it is convenient to detect the steam multiple times through the thermostat, and effective temperature control management can be implemented through the thermostat, making the vaporization effect relatively stable.
[0015] Preferably, as an improvement, a box cover is adaptively installed on the evaporation box body. An inlet water joint is connected to the box cover. There is a water outlet point corresponding to the inlet water joint in the vaporization flow channel, and a diversion column is provided at the water outlet point.
[0016] Beneficial effects: By adopting the above technical solution, it is convenient for water to contact the diversion column, which plays a certain role in guiding the water and avoids the water flowing into a relatively far place in the vaporization flow channel, improving the vaporization speed and effect.
[0017] Preferably, as an improvement, the isolation rib group further includes a third isolation rib. A circulation section is formed between the second isolation rib and the third isolation rib. The steam flow paths of the starting section and the circulation section are overall opposite.
[0018] Beneficial effects: By adopting the above technical solution, it is convenient to extend the length of the vaporization flow path, and the circulation section is close to the starting section, making the structure more compact. Moreover, the vaporization path is relatively extended, enabling more sufficient vaporization. That is, the circulation section is also convenient for absorbing heat in the high-temperature area, further and continuously heating the steam, maintaining the steam in a high-pressure and high-temperature state, and preventing the occurrence of liquid phenomena.
[0019] Preferably, as an improvement, a confluence section is formed between the vaporization flow path and the inner wall of the evaporation box body. One end of the confluence section is connected to the circulation section, and the other end of the confluence section is connected to the steam outlet.
[0020] Beneficial effects: By adopting the above technical solution, not only is the vaporization path further extended, but also the heat generated on both sides of the heating body can be further absorbed, contributing to energy conservation and maintaining a stable temperature.
[0021] Preferably, as an improvement, the built-in spacing between the two sides of the confluence section is 4.5 - 6.5 mm.
[0022] Beneficial effects: By adopting the above technical solution, the built-in spacing between the two sides of the confluence section is reasonably arranged to avoid obvious airflow noise when the equipment is running, that is, when the steam flows through, improving the user experience.
