Abstract

The utility model relates to a constant-temperature water cup, and belongs to the technical field of the heat engineering. The utility model is characterized in that the cup body is composed of a heat storage interlayer, an insulating layer and an outer shell from the interior to the exterior. The heat storage interlayer is filled with phase transition material which is used for storing the storing and regulating the temperature. The insulating layer adopts the common insulating material or a glass vacuum sleeve which is a thermal insulation bottle container. The utility model causes the poured hot water to fast reach to and keep the fundamentally constant temperature of 50-70 DEG C suitable for mouth for a long time. The utility model is a water drinking appliance with high efficiency, temperature regulation and thermal insulation.

Description

Constant temperature water cup

The utility model is a kind of highly effective thermoregulation, insulation drinking-water apparatus, belongs to the heat power engineering field.

Common in the market thermos cup great majority adopt vacuum insulation or conventional insulation thermal insulation of materials.From operating position, though the former heat-insulating property is good, need the long time but drop to the temperature that can drink by boiling water, give to drink and make troubles, and the relatively-high temperature of long period, can cause drink such as loss of nutritive components such as tealeaves, fruit juice and destruction to drink taste; On the other hand, but that drink remains on time of agreeable to the taste temperature 70-50 ℃ is shorter.Then temperature retention time is not long because heat-insulating property is relatively poor for the latter.

The purpose of this utility model is to overcome the shortcoming of above-mentioned thermos cup, and a kind of Constant temperature water cup of superior performance is provided.

The utility model mainly is made up of the bowl cover 1 with air blanketing, heat accumulation interlayer 5, heat insulation layer 4 and housing 6.Wherein bowl cover uses the hard non-toxic plastic; The heat accumulation interlayer uses stainless steel or glass, perfusion paraffin in the heat accumulation interlayer; Heat insulation layer uses conventional insulation material or glass evacuated cover, i.e. glass liner of thermos; Housing can be selected different materials according to different needs; Heat accumulation interlayer upper end is for preventing to melt because of paraffin the headroom of the superpressure that expands.

The utlity model has following advantage:

1. adopt paraffin as the phase transformation charges in the heat accumulation interlayer, its phase transition temperature is about 60 ℃, is just meeting the needs of the agreeable to the taste temperature of drink, and paraffin source sufficient, pollution-free, no corrosiveness, safe in utilization.

2. utilize paraffin heat absorption when carrying out solid-liquid phase change, heat release and temperature keeps constant principle, 70 ℃ of the temperature that the boiling water that pours in the cup is reduced to rapidly can drink, and in 4 hours, remain on agreeable to the taste temperature range 70-50 ℃.Still can remain on about 40 ℃ through 8 hours temperature.In actual use, owing to constantly drink, add water, the water in the cup temperature can remain between 65-55 ℃, and this humidity province is the most agreeable to the taste.

3. owing to the good temperature adjusting performance of this water tumbler, can avoid long high temperature to destroy the nutritional labeling of drink, thereby be particularly suitable for Instant Drinks tea, fruit juice and various auxotype drink.

4. this water tumbler has constituted composite heat-insulating layer by reservoir and heat insulation layer, thereby its overall heat insulation effect is better than general insulation water tumbler.

Description of drawings:

1. Fig. 1 is for adopting the cutaway view of the present utility model of common heat-insulation layer.

2. Fig. 2 is for adopting the cutaway view of the present utility model of glass evacuated interlayer.

3. Fig. 3 is for after pouring boiling water in this novel cup and adding a cover, the time dependent typical curve of water temperature.

4. Fig. 1 and Fig. 2 all can be used as explanation illustration of the present utility model.

5. used structure sequence number is in full accord among Fig. 1 and Fig. 2.1-bowl cover among the figure; The 2-headroom; 3-paraffin; The 4-heat insulation layer; 5-heat accumulation interlayer; The 6-housing.

Below enforcement of the present utility model is described further:

After pouring into boiling water in the cup, the paraffin heat absorption in the reservoir is melted, and makes the water in the cup temperature reduce to agreeable to the taste temperature rapidly; In heat radiation process thereafter, the paraffin of thawing begins to solidify, and constantly emits latent heat, makes the water in the cup temperature remain on agreeable to the taste temperature for a long time, thereby plays temperature adjustment and insulation effect, has realized that drink is at the relative constant temperature of agreeable to the taste temperature province in the cup.If drink in the middle of considering again and add boiling water, by interlayer paraffin melt, the adjusting of heat absorption, heat release when solidifying, can make more that beverage remains at about 60 ℃ of the most agreeable to the taste temperature in the cup.

Claims

1, a kind of Constant temperature water cup is characterized in that it is made up of heat accumulation interlayer, heat insulation layer and housing, and the heat accumulation interlayer is an internal layer; Heat insulation layer is in the reservoir outside; Housing then is the outermost layer that surrounds heat insulation layer.

2, water tumbler according to claim 1 is characterized by in the heat accumulation interlayer and does the phase transformation charges with paraffin.

3, water tumbler according to claim 1 is characterized by the headroom that superpressure preventing is arranged in the heat accumulation interlayer of sealing.
