detailed description

The specific implementation manner of the present utility model is described in detail below in conjunction with accompanying drawing. It should be understood that the specific embodiments described here are only used to illustrate and explain the utility model, and are not intended to limit the utility model.

It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

In the present utility model, in the case of no contrary description, the used orientation words such as "up, down, top, bottom" are usually for the direction shown in the drawings or for vertical, vertical or gravity The terms used to describe the mutual positional relationship of each component in terms of direction. Orientation words such as "inner and outer" usually refer to the inside and outside of the chamber relative to the evaporation chamber and the like.

The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

Referring to Fig. 3, the utility model provides a new type of steam generator, including a steam generator housing 13, an evaporation chamber is formed in the steam generator housing 13, and a device is arranged in the evaporation chamber to heat the water in the evaporation chamber. The primary heating body 11 for evaporating and the secondary heating body 12 for reheating the steam. Wherein, the steam generator 1 also includes a thermal insulation layer 14 for blocking the heat radiation of the secondary heating body 12 or conduction to the steam generator casing 13, and the thermal insulation layer 14 is arranged at intervals between the steam generator casing 13 and the two sides. between the secondary heating bodies 12.

As a general gist, the utility model is to prevent the heat of the secondary heating body 12 from escaping. Therefore, compared with the conventional steam generator shown in FIG. 2, the new steam generator of the utility model shown in FIG. The heat layer 14 can effectively isolate the heat radiation of the secondary heating body 12 to the steam generator shell 13, reduce the temperature of the steam generator shell 13, and prevent the adjacent electric control board 50 from being damaged and the steam guide tube 30 from being heated and melted And so on.

Obviously, in order to realize the heat insulation function, the heat insulation layer 14 is preferably made of a heat insulation material, that is, a material with high temperature resistance and low thermal conductivity, such as a conventional silica gel layer formed of a silica gel material. Of course, other materials or composite materials that meet the characteristics of heat resistance and low thermal conductivity can be used, such as PPT materials and the like. The heat insulation layer 14 is not limited to a single material layer, and other heat insulation materials can also be coated on the inner surface of the heat insulation layer 14, and the heat insulation layer 14 can also be a hollow structure filled with heat resistance materials.

Further, a heat radiation reflective layer is formed on the inner surface of the heat insulation layer 14 to reflect most of the heat of the secondary heating body 12 back into the evaporation chamber, thereby reducing the heat absorption of the heat insulation layer 14 and lowering its own temperature. The heat radiation reflective layer can be formed by changing the design of the material, color or surface finish with high heat reflective performance, and can also be changed to enhance the heat reflectivity by changing the surface shape, such as improving the surface shape of the heat insulating layer 14 as much as possible to surround The arc or arch of the heat source to enhance heat reflection. In short, those skilled in the art can understand that the material, shape, structure, etc. of the heat insulation layer 14 are not limited to those shown in FIG. can be.

However, the heat insulation layer 14 covers at least the surrounding area of the secondary heating body 12 , that is, the area subject to strong heat radiation or heat conduction, so as to block the heat of the secondary heating body 12 from escaping to the greatest extent. As shown in Figure 3, the evaporation chamber of the steam generator includes a water chamber located below the liquid level and a steam chamber located above the liquid level, and the primary heating body 11 is arranged in the water chamber to heat water to form low-temperature water vapor , the secondary heating body 12 is arranged in the steam chamber to reheat the low-temperature water vapor to form high-temperature water vapor. In the illustrated embodiment, the heat insulation layer 14 at least fully covers the inner wall of the steam generator housing 13 in the steam chamber, that is, the entire area that can be affected by the heat of the secondary heating body 12 . Referring to FIG. 3 , the inner wall of the steam generator housing 13 includes the inner peripheral wall of the steam generator housing 13 and the inner wall of the top cover.

Due to the low thermal conductivity of the insulating layer 14, it generally does not absorb much heat by itself. However, in order to protect the heat insulation layer 14 and further reduce heat loss, the heat insulation layer 14 in FIG. 3 also specifically includes a water-touching portion 141 at the bottom, and the water-touching portion 141 extends downwards below the liquid level of the water chamber. . In this way, at least a portion of the heat insulation layer 14's own heat can be absorbed by the water, thereby reducing the portion of heat that can be conducted to the steam generator housing 13 .

In addition, a steam outlet A is formed on the top cover of the steam generator housing 13 . The heat insulation layer 14 includes a clamping portion 143 at the top, and the heat insulation layer 14 extends upward from the inner wall of the top cover of the top cover to cover the inner peripheral wall of the steam outlet A and is clamped to the top of the steam outlet A through the clamping portion 143 perimeter. In this way, the heat insulation layer 14 covers the inner peripheral wall of the steam outlet A. After the steam guide pipe 30 is connected to the steam outlet A, the heat emitted by the secondary heating body 12 can only be dissipated outward along the steam channel, and the steam heating. At the same time, after the top of the heat insulation layer 14 is clipped to the top peripheral edge of the steam outlet A through the clamping portion 143 , the heat insulation layer 14 can be effectively fixed to make the installation firm and stable.

Through the structural design of the heat radiation reflective layer, the water-contacting portion 141 , and the clamping portion 143 , the thermal insulation layer 14 absorbs less heat, and the temperature itself can be cooled and the installation is stable. However, the external dissipation of the heat insulation layer 14's own heat also needs to be reduced as much as possible. For this reason, in FIG. 3 , the outer wall surface of the heat insulation layer 14 and the inner wall surface of the steam generator housing 13 are particularly spaced apart from each other to form an air gap layer. The thermal conductivity of the air is significantly lower than the metal material of the steam generator housing 13 or the material of the heat insulation layer 14 . In addition, the heat insulation layer 14 may include a plurality of connection shell parts 142, and the multiple connection shell parts 142 are arranged at intervals on the outer wall surface of the heat insulation layer 14 and form ribs from the outer wall surface of the heat insulation layer 14 to The outer protrusion, the connecting housing part 142 is connected to the inner wall of the steam generator housing 13 through the air space layer. Through the plurality of rib-shaped connecting shell parts 142, not only the heat insulation layer 14 with a larger fixed area is supported more firmly and stably, but also the contact area between the heat insulation layer 14 and the steam generator shell 13 is greatly reduced. The self-heat escape of the heat insulation layer 14 is further reduced.

When the heat-insulating layer 14 absorbs less heat and dissipates less heat, obviously the temperature of the steam generator housing 13 on the outside of the heat-insulating layer 14 can be greatly reduced, without affecting the steam pipe 30 and the electric control board. 50 produces a hazard.

It should be noted that a water inlet B is provided on the circumferential casing part around the water chamber of the steam generator casing 13, and the water inlet B is connected with the water tank 20 through a water inlet pipe to supply water to the water chamber. There is usually a minimum water level and a maximum water level in the evaporation chamber, the primary heating body 11 is set below the minimum water level, and the secondary heating body 12 is set above the maximum water level. The heat insulation layer 14 can go over the water inlet B downwards to insulate and protect at least the inner wall of the housing above the water inlet B, and use the water from the water inlet B to flush the heat insulation layer 14 to reduce the temperature. In addition, a water level gauge can be installed in the water chamber, and a liquid level controller and a water pump can be installed in the garment steamer to monitor the water level in the water chamber, and timely and appropriate water can be replenished through the water pump to keep the water level at the lowest level and the water level at the highest level. Between the water levels, while not damaging the heating body and other components, it can continuously output high-temperature heating steam to the outside.

The appearance and structure of the garment steamer adopting the novel steam generator 1 of the present utility model is the same as that of the conventional garment steamer in FIG. 1 . In terms of composition and structure, it includes a main body 10, a steam guide pipe 30, a spray head 40 and an electric control board 50. The main body is provided with a water tank 20. The spray head 40 communicates with the steam chamber of the steam generator 1 through the steam guide pipe 30, and the water tank 20 The pipeline is connected to the water chamber of the steam generator 1 . Wherein the electric control board 50 is usually installed in the main body 10 and close to the steam generator housing 13, and the closest distance between the two is usually several millimeters, so in FIG. Burns, thus there is a need for thermal protection. Through the setting of the heat insulation layer 14 in FIG. service life and improve product performance.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model, for example, from the name , the difference between the secondary heating body 12 and the primary heating body 11 lies in the heating sequence, so in theory it can further have a tertiary heating body, a quaternary heating body, etc., or in other words, the secondary heating body 12 is not limited to the one shown in FIG. 3 A single heating body can also be a plurality of independent heating units arranged at intervals along the height direction in the steam chamber, and such changes should be included in the protection scope of the present invention.
