Abstract
The invention provides a dish with a heat storage function and belongs to the technical field of articles for daily use. The dish comprises a dish body, the dish body is of a two-layer structure with a cavity in the middle, and a heat storage device is installed in the cavity. The heat storage device comprises a heat storage material layer, a bag wrapping a heat storage material and a heat-isolation layer. The heat-isolation material is a phase change heat storage material. The dish can cool high-temperature meals after making contact with the high-temperature meals, and heat can be preserved after the meals are cooled. After the dish is sterilized with hot water and taken out, the dish can release heat to achieve the automatic drying effect. The dish is simple in structure and stable in temperature control, and has the effects of energy conservation and environmental friendliness.
Description
Technical field
The invention belongs to daily living article technical field, particularly relates to a kind of dishes having heat storage function.
Background technology
Present thermal-insulative bowls and plates majority employing vacuum insulation or the method utilizing electric heater unit to heat realize the insulation to dishes.Utilize the method simple in construction that vacuum method is adiabatic, but heat insulation effect is poor；And utilizing the dishes that electric heater unit is incubated, structure is complicated, and price is high, and form is heavy and restriction by power supply, and the seal request of circuit is high, and is not easy to washing, is not suitable for very much daily life.Repeatedly electrical heating power consumption is serious, is unfavorable for environmental protection and saving.
After dish washing, Chang Buneng completely removes the remnants tiny globule on the surface of dishes, and antibacterial is prone to grow, and affects food safety, and traditional dishes drying apparatus is expensive, and area occupied is big.Dishes does not also have the function of autonomous drying.
For above-mentioned Problems existing, it is badly in need of a kind of simple in construction, high insulating effect, energy-conserving and environment-protective, it is possible to continue the dishes independently generated heat to reach autonomous drying function.
Summary of the invention
The purpose of the invention is to provide a kind of dishes having heat storage function, and food can be made when containing high temperature food to be quickly down to middle temperature, and protection human body is not burned, and after food cooling, dishes releases again heat, makes food cooling too not fast.Terminating in dining, after hot water high-temperature sterilization, dishes utilizes the heat absorbed, and automatically dries dishes, meets the requirement of energy-conserving and environment-protective.
In order to solve technique scheme, the invention adopts the following technical scheme that:
1. having a dishes for heat storage function, including dishes main body, described dishes main body is the middle double-decker for cavity, it is characterised in that have heat-storing device in described cavity, including heat accumulating layer, the capsule wrapping up heat accumulating and thermal insulation layer.
2. heat accumulating layer as claimed in claim 1, it is characterised in that: heat accumulating is a kind of covert wax, and fusing point is between 60-80 (DEG C), and specific heat is in that 2.0J/ (g. DEG C), and the heat of transformation is more than 200J/g, and volume change is less than 10%.Heat accumulating layer is evenly distributed in the cavity of dishes body.
3. the capsule wrapping up heat accumulating as claimed in claim 1, it is characterised in that: described capsule is one layer of polyethylene film closed, the fully wrapped around heat accumulating layer of capsule.
4. thermal insulation layer as claimed in claim 1, it is characterised in that: described thermal insulation layer is positioned at the lower surface of cavity, and material is polyurethane foam.
5. heat-storing device as claimed in claim 1, it is characterised in that: being full of heat accumulating in capsule, volume shared by capsule is not more than the 90% of the cavity volume removed outside thermal insulation layer volume.
The operation principle of the invention is as follows:
After temperature contains dishes higher than the high temperature food of covert wax fusing point, covert wax is become liquid from solid-state, absorbs heat, makes food temperature rapid decrease.When food temperature begins to decline, to lower than time below covert wax fusing point, covert wax is become solid-state from liquid, makes food cooling not too fast, plays the effect of insulation.
After dining terminates, when dishes being sterilized higher than the high-temperature water of covert wax fusing point by temperature, covert wax absorbs high-temperature water heat, liquid is become from solid-state, after taking out from high-temperature water, ambient temperature is lower than covert wax melting temperature, covert wax is become solid-state from liquid, releases heat, and dishes dries surface moisture automatically.
Compared with prior art, the invention has the characteristics that and beneficial effect:
1, the invention provides and a kind of uses phase change material to make dishes be provided with heat storage function, and simple in construction is convenient and practical.Overcome and use the defect that Electric heating thermal-insulative bowls and plates structure is complicated, rely on power supply, reduce structure complexity, overcome the dependence to power supply.
2, phase change material stable temperature control, overcome the defect of the bad temperature control of dishes of Electric heating, it is to avoid use temperature-adjusting circuit, reduces cost, increases stability.
3, high temperature food can play the effect of fast cooling, and protection human body is not burned, and high temperature food fast cooling can accelerate dining speed.
4, after dining terminates, when cleaning dishes with hot water, dishes absorbs heat and releases heat after taking out from hot water, plays the effect of drying automatically, and the dishes body of drying makes antibacterial not easily grow, and protects health.
5, the invention utilizes food self heat that food is incubated, and utilizes hot water heat that dishes is dried, has the effect of energy-conserving and environment-protective.

Detailed description of the invention
In order to make the purpose of the invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
The invention embodiment provides a kind of dishes having heat storage function, comprises dishes body 1, and institute's dishes body has cavity 2, has a heat-storing device in cavity, and described heat-storing device includes:
Heat accumulating 5, the capsule 3 wrapping up heat accumulating and thermal insulation layer 4；
Heat accumulating 5 is a kind of covert wax, and the covert wax fusing point of the present invention is selected in 60 (DEG C).Dishes can be lowered the temperature after contacting with high temperature food, can be incubated after food cooling.
The capsule 3 of parcel phase change material must have enough elasticity, also should have better thermostability.This example uses one layer of polyethylene film closed.
Described thermal insulation layer 4 is positioned at the lower surface of cavity, it is possible to prevent scattering and disappearing of heat, it is also possible to prevent excessive temperature from causing the scald to human body.The heat-barrier material used in this example is polyurethane foam.
