Abstract
A rollable cover for freezing compartments and cooling cabinets used in supermarket stores etc., which covers the boxes/cabinets when not open for removal of goods or display. It comprises a pliable, thermal insulating material which can be rolled on to the compartment to cover its opening, and rolled up after being used. The base material(13) is a laminate of plastic sheets enclosing air bubbles(14), with an exposed light reflecting surface. The base material(13) is provided with reinforcing bars(16A-D) which are attached with tapes adhered or welded to the base material. At least one edge of the base material(13) is bordered with a reinforcing tape(18) for supporting the rolled up cover when stored.
Description
Technical field
The present invention relates at the household freezer of places such as supermarket application and the lid that winds up of cooling cabinet use, when not showing goods, this lid is covered with such case/cabinet, and it also allows to carry out putting into and taking away of goods.
Background technology
When showing cooled freight, when showing frozen product, heat energy will cause the loss of energy to transmission all around especially.In addition, the temperature of goods in opening, the household freezer that exposes will be higher than the temperature in the household freezer of sealing.This storage life to goods is unfavorable.In addition, the condensation in the cooler bin of opening increases, thereby requires more frequent deicing.
The known cover layer made from foamed plastics and similar thermal insulation layer material, their beddings are on the opening of case and cabinet cooling cabin.But these known lids are heavier and expensive.Sometimes, the condensed water in the ambient air is deposited on upper surface, has reduced thermal insulation capabilities.
Summary of the invention
Main purpose of the present invention is to propose the lid that a kind of supermarket cooling cabin is used, and it is not only light but also more cheap than existing lid.What more recommended is that it is easy to spread out and sweep away.
Its purpose also is to propose a kind of lid, and it can discharge condensed water, thereby has reduced the deicing frequency.
The invention provides a kind of lid that winds up, the freezing room and the cooling cabinet that are used for supermarket etc., this lid at case/cabinet is not opened to take goods away or when showing, cover case/cabinet, the described lid that winds up comprises the heat insulator that one deck is pliable and tough, can spread out on the cabin to cover its opening, and after use, wind up, this covers four edges cover openings that pass through contact openings under the state of spreading out, heat insulator is made of porous material, it is characterized in that basic material is a kind of laminate that surrounds the plastic layer of air bubble, and have the reflecting surface that exposes; Basic material is provided with stiffener, and these stiffeners are with adhesive tape bonding or be soldered on the basic material, and basic material has at least an edge to stud with reinforcing band, the lid that winds up in order to supporting when storing.A kind of lid like this will be called as " heat lid " hereinafter, and it can be adopted simple method to make by cheap raw material.When it became web-like to store, the confining surface of lid and structure thereof were drained water.Reflecting surface reduces the heat that absorbs from incident ray.Thereby reduced the condensation of the water on the Re Gai two sides.
Description of drawings
Hereinafter will be illustrated the present invention in conjunction with the accompanying drawings, wherein
Fig. 1 is a perspective view with household freezer of the heat lid that the present invention proposes.
Fig. 2 is the part downside of heat lid among Fig. 1, and
Fig. 3 is the cross section along III-III line among Fig. 2.
Household freezer 11 shown in Figure 1 has opening upwards.What be covered with this opening is the heat lid 12 that a present invention proposes, and its edge is placed on the side and end of household freezer.
The specific embodiment
The details of heat lid 12 is shown in Fig. 2 and 3, and its basic material 13 is for surrounding the plastic layer of air bubble.This material is by constituting with the lower part, i.e. cover layer 13A (the clearest in Fig. 3), and it is the laminated product of polyester layer, and has outer metal cladding; Inner plastic layer, i.e. " bubble layer " 13B, it is soldered on the described ground floor so that in hole or air " bubble " 14 be enclosed in; And the second cover layer 13C.In this example, the parts of plastics among cover layer 13A, bubble layer 13B and the second cover layer 13C is all made by polyethylene.
Can develop other basic material with corresponding construction and corresponding weight, cost and hot property.
For adding heat-flash lid 12, be provided with stiffener 16A-D (Fig. 1), it crosses the longitudinal axis of heat lid and stretches, and every inner width that slightly is shorter than household freezer 11.Find, preferably shown in Fig. 2 and 3, stiffener 16A-D is assembled on the second cover layer 13C of basic material 13, rather than among production period is included in them basic material 13.
The assembling of Fig. 2 and 3 expression stiffener 16A-D, they are that the adhesive tape 17 that is used on the stiffener both sides connects on basic material 13.Adhesive tape 17 can be known narrow fabrics substrate and tack coat type, is used for being connected to enduringly the described second cover layer 13C.Stiffener 16A-D slightly is shorter than the width of heat lid 12, thereby makes the end of stiffener be able to be covered fully by the end of adhesive tape, adhesive tape be connected to the stiffener end near.
In addition, the side and the end margin of heat lid are covered by a kind of marginal belt 18 similar in appearance to adhesive tape 17.Marginal belt 18 has double purpose.At first, its objective is that the edge that prevents heat lid 12 is torn during winding up and spreading out.Secondly, it helps the upright storage of heat lid volume, and can not decreased base.Upright purpose of storing will be described hereinafter.Marginal belt 18 can also prevent that the basic material of lamination from being polluted.With 17 and 18 also the available energy material that is soldered to basic material 13 substituted.
Stiffener 16A-D in this example is a plastic tube, the pipe similar as pipe in structure and the electric installation.This pipe has low weight, high resiliency and necessary strength.In addition, this pipe also is easy to install.
Also can be used for cooling cabinet as the corresponding heat lid in example.At this moment, be preferably in the cooling cabinet top and connect a kind of trade mark and be the band of " Velcro ", and cover in heat corresponding band is set.Heat is covered at the top and is connected, and rolls down along the place ahead of cabinet opening.
When using, promptly use the hot shop of covering at closing time, spread out lid to cover the opening of household freezer and cooling cabinet.When using the heat lid, cooling in the cabin or cryogenic temperature can keep better, thereby have reduced power consumption.Sometimes, during using the heat lid, the reduction of power consumption can reach 25% to 35%.Think that these superior performances are based on that invention proposes, used material and reflecting surface combine and used stiffener.This lid in light weight, and material price is cheap.
When open the door in the shop, heat lid is taken away from household freezer, condensed water with major sedimentary on upper surface.Because sealing but the surface of a fixed structure is arranged, this water will keep from the teeth outwards, especially on the horizontal freezing case.During daytime, the heat lid that winds up is erectly deposited.Thereby water will be drained, heat lid 12 with desiccation so that use next time.
