A pumpless water heating mattress with a single pressure chamber structure

Abstract

The invention discloses a pump-free water heating mattress provided with a single pressure chamber structure. The pump-free water heating mattress comprises a mattress body provided with a warm water pipe inside, wherein one end of the warm water pipe is connected with a water outlet pipe of a water supply device, the other end of the warm water pipe is connected with the water supply device by virtue of a return water pipe, the water supply device comprises a water tank and one pressure chamber arranged below the water tank, a water adding hole is formed in the water tank, and a movable valve block opened along the water feeding direction is arranged between the water tank and the pressure chamber; and the pressure chamber is communicated with the water outlet pipe by virtue of a water delivery pipeline, the water delivery pipeline comprises a heating section and a heat exchange section composed of a heat exchanger, an electric heating tube sheathes outside the heating section, the electric heating tube is electrically connected with an electric control mainboard, the heat exchange section is arranged in the water tank, a separating cover is arranged outside the heat exchange section, and a water inlet exhaust valve is arranged at the top of the pressure chamber. The pump-free water heating mattress has the advantages of simple structure, comfort in application, no noise due to adoption of a pump-free structure for delivering water and high heat utilization ratio.

Description

technical field [0001] The invention relates to the technical field of water heating mattress manufacturing, in particular to a pumpless water heating mattress with a single pressure chamber structure. Background technique [0002] In the cold winter, electric heating mattresses are often used for heating in the south, but since electric heating mattresses generate heat through electric heating wires laid in the mattress, there are certain safety hazards. Reports of human injury are also common. At present, an alternative product of an electric heating mattress, that is, a water heating mattress, has appeared on the market; the water heating mattress is welcomed by people because of its good safety and comfort. [0003] In the existing water heating mattress, the water in the water tank is heated by a hot water pump and delivered to the mattress, and the water in the mattress flows back into the water tank, thereby realizing the recycling of water. But the work of heat pum...

Problems solved by technology

However, the operation of the hot water pump will produce sound, which is particularly obvious in quiet nights and will affect the quality of sleep of users. Moreover, as the working time of the water pump increases, the noise will become louder and louder.

In addition, a pumpless water heating mattress with a single pressure chamber structure currently on the market has a slow water flow rate. When the high-temperature water entering the mattress slowly flows to the end, the temperature will drop a lot, resulting in temperature differences in various parts of the mattress. , people lying on it at night will feel the obvious temperature difference, resulting in a decrease in comfort

At present, the movable valve plate of the pressure plug water inlet mechanism used in some products is set directly against the heating tube, and the air bubbles generated when the heating tube is heated will have an impact on the movable valve plate, which will affect the service life of the movable valve plate, so its The structure needs to be further improved
