Description

一种保温壶技术领域 Insulation pot

本发明涉及液体保温装置领域，更具体的说是一种具有高效保温性能和外形美观的保温壶。 The invention relates to the field of liquid heat preservation devices, and more particularly to an insulation pot with high heat preservation performance and beautiful appearance.

技术背景 technical background

现有用于盛水的水壶有多种结构，居其应用领域的不同采用不同的保温结构。如仅用于盛水的咖啡壶、茶壶等产品，一般采用双层壶壁结构，进一步可以将壶壁之间抽真空，更具保温效果；或者是内层采用隔温防水材料，如陶瓷，外层采用不锈钢作为装饰层。用于直接加热的直热式热水壶，由于加热装置持续提供热量给热水壶，所以一般不采用保护结构，多数由单层金属一体成型构成，成本低。而对于内置有加热装置的电热水壶，结构是在设有加热装置的金属内胆的外侧加设一个外壳，外壳主要起到支撑、隔温防烫和装饰的效果。由于也是采用持续加温结构，所以对保温效果的要求不高，可以在外壳和内胆之间填充发泡材料起到一定的保温作用。 The existing water bottles for water contain a variety of structures, and different insulation structures are used in different fields of application. For example, the coffee maker, teapot and other products used only for water, generally adopt double-layer pot wall structure, and further can vacuum the pot wall to provide more heat preservation effect; or the inner layer is made of temperature-proof waterproof material, such as ceramics. The outer layer is made of stainless steel as a decorative layer. The direct-heating type hot water bottle for direct heating generally does not employ a protective structure because the heating device continuously supplies heat to the hot water bottle, and most of them are integrally formed of a single-layer metal, and the cost is low. For the electric kettle with built-in heating device, the structure is provided with an outer casing on the outer side of the metal inner tank provided with the heating device, and the outer casing mainly serves as a support, a temperature-proof anti-scalding and a decorative effect. Since the continuous heating structure is also adopted, the requirement for the heat preservation effect is not high, and the foaming material can be filled between the outer casing and the inner liner to maintain a certain heat preservation effect.

虽然针对不同的应用领域存在不同的热水壶结构，均具有其自身的优点，不过也存在各种各样的缺点。采用双层壶壁结构，并进行抽真空，这种结构虽然保温效果好，不过其制作成本十分高，并且仅仅适用于盛水的水壶，不能够被加热。单层金属壶体结构成本低廉，不过几乎不具有保温效果，需要通过持续加热来保持温度，因此浪费大量能源。陶瓷内胆、金属外壳的结构，金属外壳的作用仅仅是装饰而已，由于金属对颜料的附着能力很差，不适合图案喷绘等装饰效果；而且由于陶瓷内胆导热效果差，这种结构也不适用于加热。内置加热装置的电热水壶结构，这种结构一般适用于大型加热壶，采用固定式供水，不便于移动。而且其外壳一般采用塑料或金属制作，主要起到装饰作用而已，保温性能主要由外壳和内胆之间的空气层或发泡材料来实现，保温效果十分一般。因此可以看出现有的热水壶的保温效果十分一般，进一步导致了加热效率低，能源浪费等问题。而保温效果好的结构却难以用于加热，或制作成本太高，装饰效果也显得低档。 Although different kettle structures exist for different application fields, they all have their own advantages, but there are also various disadvantages. The double-walled wall structure is used and vacuum is applied. Although this structure has good heat preservation effect, its production cost is very high, and it is only suitable for water-filled water bottles and cannot be heated. The single-layer metal kettle body structure is low in cost, but has almost no heat preservation effect, and needs to be maintained by continuous heating, thereby wasting a lot of energy. The structure of the ceramic liner and the metal shell, the role of the metal shell is only the decoration, because the adhesion ability of the metal to the pigment is very poor, it is not suitable for decorative effects such as pattern printing; and because the ceramic inner tank has poor thermal conductivity, this structure is not Suitable for heating. The electric kettle structure with built-in heating device is generally suitable for large heating pots. It is fixed water supply and is not easy to move. Moreover, the outer casing is generally made of plastic or metal, and mainly serves as a decorative effect. The thermal insulation performance is mainly realized by an air layer or a foamed material between the outer casing and the inner casing, and the heat preservation effect is very general. Therefore, it can be seen that the insulation effect of the existing hot water bottle is very general, which further leads to problems such as low heating efficiency and waste of energy. The structure with good thermal insulation effect is difficult to use for heating, or the production cost is too high, and the decorative effect is also low.

发明内容本发明的目的在于克服现有技术中的缺陷，提供一种具有高效保温性能，结构简单，且能够进行精美装饰的保温壶。 Summary of the invention SUMMARY OF THE INVENTION The object of the present invention is to overcome the deficiencies in the prior art and to provide an insulated pot which has high heat-insulating properties, is simple in structure, and can be beautifully decorated.

本发明通过以下技术方案实现其目的。 The present invention achieves its object by the following technical solutions.

本发明设计的保温壶，结构至少包括壶体、壶盖和设于壶体一侧向外延伸的壶嘴，其主要设计结构是所述壶体的侧壁包括内胆、填充层和外壳三层结构，所述内胆由金属材料制成，填充层由隔温填充材料构成，外壳由陶瓷材料制成。本发明的设计重点在于每一层所采用的材料及其结构构成，各个层均具有重要的功能。内胆采用金属材料制作，一般是采用不锈钢一体冲压成型的壳体，其目的是直接用于盛装液体。金属材料具有导热快，造型多样化，制作简单等优点，所以能够适用于加热型的保温壶使用。且金属内胆具有镜面反射作用，能够减少壶内液体对外部的热辐射导致的热量散发。隔热材料填充在外壳和内胆之间，形成一个填充层，起到保温、隔热和消音的作用，一般采用发泡材料填充。外壳采用陶瓷材料制作，形成了第二保温层，使得内胆中液体的热量更不容易散发，进一步提高保温效果。而且陶瓷外壳的另一优点是具有美观的装饰效果，使得壶体外观显得十分高档，可以适用于高级场所使用。陶瓷还容易进行上色和绘画，且即使在高温环境下使用也不会褪色，所以能够设计各种各样、风格各异的陶瓷外壳，使得产品类型更为多样化，适合不同层次的群体使用。 The thermal insulation pot designed by the invention comprises at least a kettle body, a kettle lid and a spout extending outward from a side of the kettle body. The main design structure is that the side wall of the kettle body comprises a liner, a filling layer and a casing. The layer structure, the inner tank is made of a metal material, the filling layer is composed of a temperature-insulating filling material, and the outer casing is made of a ceramic material. The design of the present invention focuses on the materials used in each layer and their structural composition, each layer having an important function. The inner liner is made of a metal material, and is generally a stainless steel integrally stamped housing for the purpose of directly containing liquid. Metal materials have advantages such as fast heat conduction, diversified shapes, and simple fabrication, so they can be used in heating type insulation pots. Moreover, the metal liner has a specular reflection effect, which can reduce the heat dissipation caused by the external heat radiation of the liquid in the kettle. The heat insulating material is filled between the outer casing and the inner tank to form a filling layer for heat insulation, heat insulation and sound absorbing, and is generally filled with a foaming material. The outer shell is made of ceramic material, and the second heat insulating layer is formed, so that the heat of the liquid in the inner tank is less likely to be emitted, thereby further improving the heat preservation effect. Moreover, another advantage of the ceramic casing is that it has an aesthetically pleasing decorative effect, which makes the appearance of the kettle body very high-grade, and can be applied to an advanced place. Ceramics are also easy to color and paint, and they do not fade even when used in high temperature environments, so you can design a wide variety of ceramic shells of different styles, making the product type more diverse and suitable for different levels of groups. .

由于液体是从内胆中通过壶嘴流出的，因此所述壶嘴最好与内胆为一体式结构。这样能够减少构件之间的水密件的使用，结构上也更加稳定。壶嘴可以设于壶体顶部边缘，或者是壶体侧面。后者需要穿过填充层和外壳，因此在制作外壳的时候预留安装壶嘴的孔，安装的时候将壶嘴穿过所述孔与内胆相配合，并进行焊接即可。 Since the liquid flows out of the bladder through the spout, the spout is preferably of unitary construction with the bladder. This can reduce the use of watertight members between components and is also more structurally stable. The spout can be placed on the top edge of the kettle body or on the side of the kettle body. The latter needs to pass through the filling layer and the outer casing, so that the hole for installing the spout is reserved when the outer casing is made, and the spout is fitted through the hole to the inner casing and welded.

在上述的基础结构上，本发明可以进一步衍生设计出针对不同应用领域的保温壶。第一种结构是壶体的壷底包括内胆、填充层和底座三层结构，所述内胆由金属材料制成，填充层由隔温填充材料构成，底座由金属或塑料材料制成。这种壶由于采用几乎是全方位的密封保温结构，因此具有最好的保温效果，不过不适合加热，可以用作持久保温的咖啡壶或茶壶使用。第二种结构是所述壶体的壶底为内胆的底部，内胆由金属材料制成。采用内胆的底部作为壶底，可以直接放在加热装置上加热，如火炉或电磁炉等。由于本发明具有良好的保温效果，在加热的过程中，热量不容易流失，因此提高保温壶加热的效率，相对于现有的水壶缩短了加热时间，节省了能源。. 另一种结构是在第二种结构上做进一步的改良，在壶体壶底上设有电加热装置，对于电热盘等加热装置，还可以在其外侧设有底座与外壳相配合，用于保护电热盘不与外界接触。由于具有良好的保温结构，因此无需像现有技术一样在外壳和内胆之间留有较大空气腔用于隔热，所以本发明的电热型保温壷结构可以十分紧凑，体积较小，便于携带移动，且同样具有高效的加热性能和节能效果。 In the above-mentioned basic structure, the present invention can further derivate the design of the heat preservation pot for different application fields. The first structure is that the bottom of the kettle body comprises a liner, a filling layer and a base three-layer structure, the inner tank is made of a metal material, the filling layer is composed of a temperature-insulating filling material, and the base is made of a metal or plastic material. This kettle has the best insulation effect due to its almost all-round sealing and insulation structure, but it is not suitable for heating and can be used as a long-term insulated coffee pot or teapot. The second structure is that the bottom of the kettle body is the bottom of the inner liner, and the inner liner is made of a metal material. The bottom of the liner is used as the bottom of the pot, which can be directly placed on a heating device, such as a stove or an induction cooker. Because the invention has good insulation The effect is that heat is not easily lost during the heating process, so the heating efficiency of the heat preservation pot is improved, and the heating time is shortened compared with the existing water bottle, thereby saving energy. Another structure is to further improve the second structure, and an electric heating device is arranged on the bottom of the kettle body. For the heating device such as the electric heating plate, the base and the outer casing may be arranged on the outer side thereof. The protective electric heating plate is not in contact with the outside world. Because of the good thermal insulation structure, there is no need to leave a large air cavity between the outer casing and the inner tank for heat insulation as in the prior art, so the electrothermal insulation structure of the invention can be very compact, small in size and convenient. Carrying movement, and also has efficient heating performance and energy saving effect.

本发明具有良好的隔热效果，因此可以直接用手移动壷体。对于容量较大的水壶，本发明在外壳上连接有手柄，方便保温壶的移动。 The invention has a good thermal insulation effect, so that the carcass can be moved directly by hand. For a kettle having a large capacity, the present invention has a handle attached to the outer casing to facilitate the movement of the heat preservation pot.

相对于现有技术，本发明具有以下突出的实质性特点和显著的进步。 The present invention has the following outstanding substantive features and significant advances over the prior art.

本发明采用发泡材料填充层和陶瓷外壳具有双重保温效果，能够实现高效的保温性能，很好的防止热量散发。采用金属内胆使得保温壷可以应用于直接加热的热水壶领域，加工简易。由于具有良好的保温结构，在加热时具有很高的效率，缩短了加热时间，节省了能源。陶瓷外壳不仅起到保温隔热的作用，而且具有十分美观的装饰效果，可以设计多种图案，并且上色，颜色不会因为高温而脱落。陶瓷外壳显得整个保温壶美观大方，而且具有 4艮好的防污效果，不会被油污或水侵蚀，清洁十分方便。 The foaming material filling layer and the ceramic shell have double insulation effect, can realize high-efficiency heat preservation performance, and can well prevent heat dissipation. The metal liner allows the insulation to be applied to the field of direct heating, which is easy to process. Thanks to its good thermal insulation structure, it has high efficiency during heating, shortens heating time and saves energy. The ceramic case not only functions as a heat insulator, but also has a very beautiful decorative effect. It can be designed with a variety of patterns and colored, and the color does not fall off due to high temperatures. The ceramic case looks like the whole insulation pot is beautiful and generous, and has a good anti-fouling effect of 4 inches, which is not eroded by oil or water, and is very convenient to clean.

The side wall of the kettle body 1 includes a liner 4, a filling layer 5, and The outer casing 6 has a three-layer structure, the inner liner 4 is made of a metal material, the filling layer 5 is composed of a temperature-insulating foamed filling material, and the outer casing 6 is made of a ceramic material. The bottom of the pot includes a liner 4, a filling layer 5 and a base 8 three-layer structure that cooperates with the outer casing 6. Spout 3 At the top edge of the kettle body 1, the inner liner 4 is of a unitary structure. The body 1 has an inverted cone shape as a whole, and a handle 9 is provided on the side. The structure of the heat preservation pot designed in this embodiment is mainly used for holding liquid insulation, such as tea pots, coffee pots, etc., and a filter screen can be added in the pot body to isolate tea leaves and water.

本设计基本上为全封闭式保温结构，壶盖 2可以采用隔温材料制作或加设保温结构（图中未示出），侧壁具有内胆 4、填充层 5和外壳 6三层保温结构。使用时直接在保温壶中装入调配好的咖啡或茶水，由于金属内胆 4具有镜面作用，能够防止壶内液体对外进行热辐射；发泡填充层 5 能够有效减少壶内液体通过金属内胆 4对外进行热传导；陶瓷外壳 6不仅起到隔热保温的作用，而且能够在外壳 6 画上花纹图案，花纹图案的颜色是固化在陶瓷材料中的，在陶瓷烧制的过程中便形成。壶底也同样具有内胆 4、填充层 5和底座 8三层结构，底座 8可以采用金属、塑料材料制成，具有一定的保温效果。因此，无论使用多长时间，或在任何高温的情况下，均不会脱落，外观美观大方，便于清洗。 The design is basically a fully enclosed thermal insulation structure, and the lid 2 can be made of a temperature-insulating material or an insulating structure (not shown), and the side wall has a three-layer thermal insulation structure of the inner liner 4, the filling layer 5 and the outer casing 6. . When used, the prepared coffee or tea is directly filled in the heat preservation pot. Since the metal liner 4 has a mirror surface function, the liquid in the kettle can be prevented from externally radiating heat; the foamed filling layer 5 can effectively reduce the liquid in the kettle through the metal liner. 4 External heat conduction; The ceramic outer casing 6 not only functions as a heat insulating layer, but also can draw a pattern on the outer casing 6, and the color of the pattern is solidified in the ceramic material, which is formed during the firing of the ceramic. The bottom of the pot also has a three-layer structure of the inner tank 4, the filling layer 5 and the base 8.

Therefore, no matter how long it is used, or at any high temperature, it will not fall off, and the appearance will be beautiful and easy to clean.

在壶内装入液体之后，由于具有三层的高效保温结构，因此液体能够在壶内维持很长时间温度变化不大，十分适合高温或冰冻饮料的盛装。手柄 9也便于保温壶移动，使得使用更为方便。 After the liquid is filled in the kettle, the liquid can be maintained in the kettle for a long time due to the three-layer high-efficiency heat-insulating structure, which is suitable for high-temperature or frozen beverages. The handle 9 also facilitates the movement of the thermos pot, making it easier to use.

实施例 2 Example 2

本实施例的保温壶结构如图 2所示，包括壶体 1、壶盖 2和设于壶体 1一侧向外延伸的壶嘴 3, 壶体 1的侧壁包括内胆 4、填充层 5和外壳 6三层结构，所述内胆 4由金属材料制成，填充层 5由隔温发泡填充材料构成，外壳 6由陶瓷材料制成。壶体 1的壶底为内胆 4的底部，与内胆 4一体化成型，均由金属制成。壶嘴 3设于壶体 1侧面，穿过填充层 5和外壳 6。壷体 1侧面设有手柄 9, 侧壁的三层保温结构的作用及效果如实施例 1所描述。 The structure of the heat preservation pot of the present embodiment is as shown in FIG. 2, and includes a kettle body 1, a lid 2 and a spout 3 extending outward from the side of the kettle body 1. The side wall of the kettle body 1 includes a liner 4 and a filling layer. 5 and a three-layer structure of the outer casing 6, the inner casing 4 is made of a metal material, the filling layer 5 is composed of a temperature-insulating foaming filling material, and the outer casing 6 is made of a ceramic material. The bottom of the kettle body 1 is the bottom of the inner liner 4, and is integrally formed with the inner liner 4, and is made of metal. The spout 3 is disposed on the side of the body 1 and passes through the filling layer 5 and the outer casing 6. The side of the carcass 1 is provided with a handle 9. The function and effect of the three-layer thermal insulation structure of the side wall are as described in the first embodiment.

本设计为一种直热式加热型的保温壶结构，在使用的过程中，将水装入保溫壶内，让后将保温壶置于火炉或电磁炉上进行加热。由于是直接对金属内胆 4 进行加热，能够迅速将热量传导到壶内，被液体吸收。且由于壶体 1 的侧壁具有内胆 4、填充层 5和外壳 6三层保温结构，因此大大降低壷内的液体向外散发的热量，提高了加热效率，从而节省了能源。在非加热状态下，由于壶体 1 的三层保温结构的设置，使本保温壶具一定程度的保温功能。 The design is a direct heating type heating pot structure. In the process of using, the water is put into the thermostat pot, and then the incubator is placed on a stove or an induction cooker for heating. Since the metal liner 4 is directly heated, heat can be quickly transferred to the kettle and absorbed by the liquid. Moreover, since the side wall of the kettle body 1 has a three-layer heat insulating structure of the inner liner 4, the filling layer 5 and the outer casing 6, the heat radiated from the liquid inside the crucible is greatly reduced, and the heating efficiency is improved, thereby saving energy. In the non-heating state, due to the setting of the three-layer thermal insulation structure of the kettle body 1, the heat preservation pot has a certain degree of heat preservation function.

实施例 3 本实施例提供了一种电热式的保温壶结构，如图 3 所示。与上两个实施例一样, 包括壶体 1,、壶盖 2和设于壶体 1一侧向外延伸的壶嘴 3，壶体 1的侧壁包括内胆 4、填充层 5和外壳 6三层结构，所述内胆 4由金属材料制成，填充层 5由隔温发泡填充材料构成，外壳 6由陶瓷材料制成。改良的结构在于壶体 1的壶底上设有电加热装置 7, 壶底为与内胆 4一体化成型的金属结构。所述的电加热装置 7为通用的电热盘或半导体电热装置，电加热装置 7的外侧设有底座 8 与外壳 6相配合，底座 8用于保护电加热装置 7。在底座 8上还设有开关插座 71 用于与外部的电源连接，一般采用 360。旋转式开关插座结构。本实施例的 - 壶嘴 3采用与实施例 2—样的结构，设于壶体 1侧面，穿过填充层 5和外壳 6 (图中未示出）。手柄 9设于壶体 1的顶部，为提手式结构。側壁的三层保温结构的作用及效果如实施例 1所描述。 Example 3 This embodiment provides an electrothermal heat preservation pot structure, as shown in FIG. As with the previous two embodiments, the kettle body 1, the lid 2 and the spout 3 extending outwardly from the side of the kettle body 1 include a liner 4, a filling layer 5 and a casing 6 The three-layer structure, the inner tank 4 is made of a metal material, the filling layer 5 is composed of a temperature-insulating foaming filling material, and the outer casing 6 is made of a ceramic material. The improved structure is that an electric heating device 7 is arranged on the bottom of the kettle body 1, and the bottom of the kettle is a metal structure integrally formed with the inner liner 4. The electric heating device 7 is a general electric heating plate or a semiconductor electric heating device. The outer side of the electric heating device 7 is provided with a base 8 for cooperating with the outer casing 6, and the base 8 is for protecting the electric heating device 7. A switch socket 71 is also provided on the base 8 for connection to an external power source, generally 360. Rotary switch socket structure. The spout 3 of the present embodiment adopts a structure similar to that of the embodiment 2, and is disposed on the side of the body 1 through the filling layer 5 and the outer casing 6 (not shown). The handle 9 is disposed at the top of the kettle body 1 and is a handle structure. The function and effect of the three-layer insulation structure of the side wall are as described in Example 1.

在使用的过程中，在壷体 1内装入液体，然后将开关插座 71与外部电源连接，接通电加热装置 7，电加热装置 7通过金属内胆 4底部对壶内的液体进行加热。壶体 1的侧壁具有内胆 4、填充层 5和外壳 6三层保温结构，因此大大降低壶内的液体向外散发的热量，提高了加热效率，从而节省了能源。在非加热状态，壶体 1 的三层保温能够保持壶内的液体热量不会散发，壶体底部由于持续与尚具余热的电加热装置 7接触，且密封式的底座 8内形成的空气腔也起到一定隔热保温的作用，因此壶体 1 底部的热量也不容易散发。使得本设计成为一种具有高效节能，且能够长时间保持液体温度的电热式保温壶。 In the course of use, liquid is charged into the body 1, and then the switch socket 71 is connected to an external power source to turn on the electric heating device 7, and the electric heating device 7 heats the liquid in the kettle through the bottom of the metal liner 4. The side wall of the kettle body 1 has a three-layer heat preservation structure of the inner liner 4, the filling layer 5 and the outer casing 6, thereby greatly reducing the heat radiated from the liquid in the kettle and improving the heating efficiency, thereby saving energy. In the non-heated state, the three-layer insulation of the kettle body 1 can keep the liquid heat in the kettle from being dissipated, and the bottom of the kettle body is continuously in contact with the electric heating device 7 which has residual heat, and the air chamber formed in the sealed base 8 It also plays a role in heat insulation, so the heat at the bottom of the kettle body 1 is not easily dissipated. This design makes the electric heating pot which is energy efficient and can maintain the liquid temperature for a long time.

本实施例的结构如图 4 所示，除形状外，主要结构和工作过程与实施例 3 相似。区别在于本实施例的壶嘴 3设于壶体 1的顶部边缘，与内胆 4为一体式结构，手柄 9为设于壶体 1侧面，向外延伸的结构。并且在底座 8内侧填充有发泡材料，使得壶体 1底部更具保温效果。本设计与实施例 3的设计均可以与现有电热水壶一样设置有电控装置等提高电器使用安全性的结构，这些装置可以同样安装在底座 8内侧。 The structure of this embodiment is as shown in Fig. 4. The main structure and working process are similar to those of the third embodiment except for the shape. The difference is that the spout 3 of the embodiment is disposed on the top edge of the kettle body 1 and has an integral structure with the inner liner 4. The handle 9 is a structure which is disposed on the side of the kettle body 1 and extends outward. And the inside of the base 8 is filled with a foaming material, so that the bottom of the kettle body 1 is more insulated. Both of the design and the design of the embodiment 3 can be provided with an electric control device, such as an electric control device, to improve the safety of use of the electric appliance. These devices can be mounted on the inside of the base 8 as well.

上述实施例 2、 3和 4均与实施例 1一样，陶瓷结构的外壳 6可以进行花纹图案的装饰，使得外观更具美感。而且上述壶体 1 的侧壁结构均具有高效的三层保温层，因此在壶体 1 外侧是基本上感觉不到热量的，可以直接用手接触壶体 1 侧壁，提高了使用的安全性。本发明并不局限于上述 4项实施例的具体结构，任何侧壁具有金属内胆 4、发泡填充层 5和陶瓷外壳 6的保温壶结构均属于本设计所要求保护的内容。 The above embodiments 2, 3 and 4 are the same as in the first embodiment, and the outer casing 6 of the ceramic structure can be decorated with a tread pattern to make the appearance more aesthetic.
