The invention relates to the field of water heaters, in particular to a water heater with a heat insulation device. The water heater comprises an inner container and an electrical chamber arranged on the periphery of an opening of the inner container. The opening of the inner container is formed in the electrical chamber, and a heating pipe flange is mounted at the opening of the inner container. The electrical chamber comprises an electrical element accommodating space for accommodating an electrical element, the heat insulation device is arranged in the electrical chamber and located at the periphery of the opening of the inner container, and the heating insulation device is used for isolating the heating pipe flange and the electrical element accommodating space. By means of the heat insulation device, loss of heat of hot water in the inner container can be reduced, an environment temperature value in the electrical chamber and a temperature rise value of the electrical element in the electrical chamber are lowered, the service life of the electrical element is prolonged, safety of the electrical element is improved, and heat preservation performance of the inner container is improved.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a water heater with a heat insulating device. Background technique [0002] At present, the main function of the electrical appliance room in the water heater is to install the electrical components, and the structure thereon is mainly designed for the placement of the electrical components. The electrical room is generally located at the right end of the water heater. It is open to the outside during production, which is convenient for the connection and operation of electrical components such as heating tubes, computer boards, temperature controllers, and power lines. The middle part of the electrical room is a circular heating tube flange, and the heating tube flange is Made of stainless steel, it is used to seal the inner tank and isolate the inside of the water heater from the outside world. [0003] However, the existing heat preservation measures for the electrical room of th...

Problems solved by technology

[0003] However, the existing heat preservation measures for the electrical room of the water heater are generally less, and lack the heat preservation structure of the heating pipe flange, and most of the heating pipe flanges in the electrical room are directly exposed outside.

Since the flange of the heating pipe is made of metal and has a high thermal conductivity, the heat stored in the hot water in the inner tank is transferred to the outside through the flange of the heating tube at the mouth of the tank, resulting in high ambient temperature and poor heat preservation effect at the inner tank of the water heater.

At the same time, after the electrical components are installed, the electrical room is isolated from the outside world through the maintenance cover, and the heat transferred from the flange of the heating pipe to the outside will increase the temperature in the electrical room (inner environment), so that the components in the electrical machine will not work by themselves. In addition to the temperature rise, the temperature rises further, making the working environment of the electrical components in the electrical room worse, affecting the service life of the electrical components (and their own electrical performance indicators, such as the temperature rise of the components, etc.) and the safety performance of the water heater

And because the maintenance cover is made of plastic, and there are few other insulation measures in the electrical room, the heat of the inner tank is seriously lost through the maintenance cover, which affects its overall thermal insulation performance, that is, the 24-hour inherent energy efficiency coefficient is also greatly affected

[0004] Although in the prior art, measures such as placing thermal insulation cotton at the bladder mouth can be used to prevent heat loss from the bladder mouth, but due to the poor consistency of line staff specification control, the placement of thermal insulation cotton during production is not completely controlled, making the actual use of thermal insulation cotton There is a deviation between the placement position and the intended placement position, resulting in unsatisfactory heat loss prevention effect

[0005] Based on the above description, there is an urgent need for a water heater with a thermal insulation device to solve the problem of high ambient temperature and poor heat preservation effect at the location of the water heater liner in the prior art, and to reduce the service life of electrical components and the safety performance of the water heater.
