Abstract

The utility model belongs to the technical field of a water heater with a heat generating device, particularly a vacuum water-boiling tank. The vacuum water-boiling tank comprises a liner body and a heater. A water inlet pipe and a water outlet pipe are arranged on the liner body. The heater is arranged in the liner body. The vacuum water-boiling tank is characterized in that an end cover is arranged on the liner body. The liner body and the end cover are all made from that metal inner layers and metal outer layers are combined. Vacuum layers are between the inner layers and the outer layers. An overflow valve is also arranged on a sealing liner body which is composed of the liner body and the end cover. The vacuum water-boiling tank has favorable heat insulation performance, low power consumption, safe utilization, etc. The vacuum water-boiling tank is a more ideal electric water heater.

Description

The vacuum boiled water tank

The utility model belongs to the water heater of heat-generating device technical field, particularly relates to a kind of vacuum boiled water tank.

In background technology, the electrothermal water boiling case mainly is made up of casing and heating, casing is to be made by single-layer metal book plate, and water inlet pipe and outlet pipe are housed on the casing, and casing is outer can be furnished with shell, shell generally plays insulation effect, during heater heat conduction in the case, can to water in boiling point, the tank surface temperature of this moment can reach about 95 ℃, because the metal cabinet heat radiation comparatively fast causes the very fast decline of boiling water temperature in the case, like this, need constantly repeat heating, the electrothermal water boiling case of making for this single-layer metal book plate for keeping water temperature, heat insulating ability is poor, the power consumption energy is big again, therefore, and in daily life, the both time-consuming energy that takes, impracticable again.

The purpose of this utility model is to provide a kind of good heat insulating power consumption little, not only safety but also practical vacuum boiled water tank.

The purpose of this utility model is achieved in that it comprises courage body and heater, water inlet pipe and outlet pipe are housed on the courage body, in the courage body heater is housed, it is characterized in that on the courage body end cap being housed, courage body and end cap are by metal internal layer and metal outer be combined into, and be vacuum layer between internal layer and the skin, sealing courage body is made of courage body and end cap, is provided with overflow valve in the upper end of sealing courage body.

The utlity model has reasonable in design, safe and convenient to use, energy-efficient, be the strong desirable boiled water tank of a kind of heat-insulating property.

In conjunction with the accompanying drawings and embodiments, the utility model is further specified as follows:

Fig. 1 is a structural representation of the present utility model

Fig. 2 is a structure of relief valve schematic diagram of the present utility model

Comprise courage body 2 and heater 8 with reference to accompanying drawing the utility model, water inlet pipe 9 and outlet pipe 11 are housed on the courage body 2, heater 8 is housed in the courage body 2, end cap 12 is housed on the courage body 2, courage body 2 and end cap 12 be by metal internal layer 4 and outer 3 be combined intos, and be vacuum layer 5 between internal layer 4 and outer 3, seals the courage body and be made of courage body 2 and end cap 12, between courage body 2 and end cap 12, sealing ring 11A can be installed, to improve sealing, heat insulating ability.Upper end at sealing courage body is provided with overflow valve 1, transparent pipe 7 is housed between overflow valve 1 and the water inlet pipe 9, so that observe the water level situation in the courage body 2, metallic porous sheet also is housed in the courage body 2, thermoswitch 6 is equipped with at the middle part of courage body 2, join with known electrical way between thermoswitch 6 and the heater 8, two ends up and down at sealing courage body are equipped with case lid 13 and base 10 respectively, overflow valve 1 is by valve body 15, valve gap 14, compositions such as handle 18 and stopper rod 20, valve body 15 is provided with overflow pipe 16 and water level pipe 17, spacing collar 22 is housed in the valve body 15, the upper end of stopper rod 20 flexibly connects through valve gap 14 and handle 18, be positioned on the stopper rod 20 of valve body 15 and be set with spring 19, sealing stopper ring 21 is equipped with in the bottom of stopper rod 20, the bottom energy gland of sealing stopper ring 21 is on spacing collar 22, handle 18 on the operation overflow valve 1, the sealing stopper ring 21 of stopper rod 20 bottoms can break away from spacing collar 22, overflow pipe 16 is communicated with the inner chamber of sealing courage body, and when the steam pressure in the sealing courage body is big, sealing stopper ring 21 can overcome spring 19 pressure under the effect of steam pressure, make stopper rod 20 to rising, then overflow pipe communicates with the inner chamber of sealing courage body for 16 this moments, thereby has ensured the safety of using.The using method of the electrothermal water boiling case in using method of the present utility model and the background technology is identical, does not do at this and gives unnecessary details.
