Abstract
The utility model relates to a high efficiency thermal insulation electric water heater, comprising a housing (1), an inner container (2), foaming thermal insulation layers (3) and a vacuum insulation board (4). The foaming thermal insulation layers (3) and the vacuum insulation board (4) are located between the housing (1) and the inner container (2); the vacuum insulation board (4) is covered in the foaming thermal insulation layers (3). According to the utility model, the vacuum insulation board is covered in the foaming thermal insulation layers, which keeps a certain distance between the vacuum insulation board and a heat source, contributes to preventing the increase of a heat conductivity coefficient of the vacuum insulation board and guaranteeing the thermal insulation performance of the electric water heater and also can avoid abrasion between the vacuum insulation board and the housing.
Description
Technical field
The utility model belongs to high-effeciency thermal type electric water heater field.
Background technology
Chinese utility model patent ZL201120217929.1 discloses a kind of electric heater, comprise shell, inner bag and polyurethane insulation coating, at device between inner bag and polyurethane insulation coating or between shell and polyurethane insulation coating, there is vacuum heat-insulating plate, vacuum heat-insulating plate has formed the Double insulating layer of electric heater together with polyurethane insulation coating, this structure has greatly reduced the hot water heat in inner bag and has outwards distributed, improved the heat insulation effect of electric heater, and vacuum heat-insulating plate is thinner, do not increase the volume of electric heater.Yet this structure has the following disadvantages in actual production:
If vacuum heat-insulating plate is arranged between inner bag and polyurethane insulation coating, vacuum heat-insulating plate is close to inner bag, because vacuum heat-insulating plate more approaches its temperature of thermal source, raises sooner, and temperature is higher, and thermal conductivity factor is higher, thereby causes heat-insulating property to decline;
If vacuum heat-insulating plate is arranged between shell and polyurethane insulation coating, in production process, the frequent contact friction of vacuum heat-insulating plate and shell, thus cause vacuum heat-insulating plate easily damaged, heat-insulating property declines.
In order to overcome these defects, spy improves the insulation construction of electric heater.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of high-effeciency thermal type electric water heater will be provided, and it can not only ensure the heat-insulating property of electric heater, can also prevent that vacuum heat-insulating plate is impaired.
The technical scheme that the utility model solves its technical problem employing is: it comprises shell, inner bag, insulating foam layer and vacuum heat-insulating plate, and insulating foam layer and vacuum heat-insulating plate are between shell and inner bag, and vacuum heat-insulating plate is wrapped in insulating foam layer.
Preferably, between vacuum heat-insulating plate and inner bag, be provided with the spacer bar that both are separated.The arranging of spacer bar can guarantee to leave between vacuum heat-insulating plate and inner bag the gap for filling-foam heat-insulation layer, and by the position of arrangement pitch bar, can guarantee the gap between the abundant filled vacuum heat-insulating shield of foamed material and inner bag.
Further, spacer bar is that plastic material is made, and plastics have preferably heat-insulating property, and the heat that can effectively reduce inner bag is passed to vacuum heat-insulating plate.
Further, spacer bar is that EPS material is made, and sticks on inner bag.EPS material not only has preferably heat-insulating property, and when heat-insulation layer foams, the spacer bar of EPS material can be fused in the middle of heat-insulation layer, is more conducive to the abundant foaming of heat-insulation layer.
Preferably, insulating foam layer is polyurethane insulation coating.
The utility model is compared produced beneficial effect with background technology:
1, because the utility model is wrapped in vacuum heat-insulating plate in insulating foam layer, not only make to maintain a certain distance between vacuum heat-insulating plate and thermal source, contribute to the thermal conductivity factor that prevents vacuum heat-insulating plate to increase, ensure the heat-insulating property of electric heater, but also avoided wearing and tearing between vacuum heat-insulating plate and shell.
Accompanying drawing explanation: Fig. 1 is structure cross-sectional schematic of the present utility model;
Fig. 2 is STRUCTURE DECOMPOSITION figure of the present utility model (not containing insulating foam layer).
The specific embodiment: as depicted in figs. 1 and 2, the present embodiment comprises shell 1, inner bag 2, polyurethane insulation coating 3 and vacuum heat-insulating plate 4, polyurethane insulation coating 3 and vacuum heat-insulating plate 4 are between shell 1 and inner bag 2, and vacuum heat-insulating plate 4 is wrapped in polyurethane insulation coating 3.
Between vacuum heat-insulating plate 4 and inner bag 2, be provided with the EPS plastics spacer bar 5 that both are separated.Many spacer bar 5 sticks on inner bag 2 to support vacuum heat-insulating plate 4 with rule or irregular mode, can be for example as shown in Figure 2, article 12, spacer bar is uniformly distributed into 3 circles, and 4 spacer bars of every circle make to leave between vacuum heat-insulating plate 4 and inner bag 2 gap for polyurethane insulation coating 3 foaming.
Claims (2)
1. a high-effeciency thermal type electric water heater, comprise shell (1), inner bag (2), insulating foam layer (3) and vacuum heat-insulating plate (4), insulating foam layer (3) and vacuum heat-insulating plate (4) are positioned between shell (1) and inner bag (2), it is characterized in that: described vacuum heat-insulating plate (4) is wrapped in insulating foam layer (3), between vacuum heat-insulating plate (4) and inner bag (2), be provided with the spacer bar (5) that both are separated, spacer bar (5) is made for EPS plastic material, and sticks on inner bag (2).
2. high-effeciency thermal type electric water heater according to claim 1, is characterized in that: described insulating foam layer (3) is polyurethane insulation coating.
