Abstract

The object is to improve the cleaning effect of fine bubble water containing fine bubbles, reduce the number of parts and ensure the assembling workability of a washing machine. The solution is that the washing machine comprises a water containing barrel, a water supply valve, a water filling box, a pressure tank which is arranged at the downstream side of the water supply valve and temporarily stores water supplied by the water supply valve and air, a micro bubble generator which causes micro bubbles to be precipitated in water flowing out of the pressure tank, and an air suction valve. The suction valve connects the pressure tank and the water filling box in an openable and closable manner, and is provided in a space between the pressure tank and the water filling box, and closes the space between the pressure tank and the water filling box as the pressure in the pressure tank increases, and opens the space between the pressure tank and the water filling box as the pressure in the pressure tank decreases.

Description

Washing machine Technical Field Embodiments of the present invention relate to a washing machine. Background Conventionally, a technique for generating fine bubble water containing fine bubbles such as micro bubbles called microbubbles or ultra-fine bubbles by using a pressurized dissolving device for dissolving an air component into a liquid under pressure has been attracting attention. However, in the pressure dissolving apparatus having the conventional structure, there are many components for taking in the gas to be dissolved in the liquid, and components such as a pipe for supplying the taken-in gas into the tank of the apparatus, and there is a problem in that the number of components increases, which results in complicated assembling work of the washing machine. Prior art literature: Patent literature: Patent document 1 Japanese patent laid-open publication No. 2005-95605 Disclosure of Invention Problems to be solved by the invention: thus, the washing machine is provided which can improve the cleaning effect of fine bubble water containing fine bubbles, reduce the number of parts and ensure the assembling workability of the washing machine. Means for solving the problems: The washing machine of the embodiment comprises a water tank, a water supply valve connected with an external water supply source, a water injection box for receiving water supplied from the external water supply source through the water supply valve and injecting water into the water tank, a pressurizing tank arranged at the downstream side of the water supply valve and temporarily storing the water supplied through the water supply valve together with air, a micro bubble generator for precipitating micro bubbles in the water flowing out of the pressurizing tank, and a suction valve for connecting the pressurizing tank and the water injection box in an openable and closable manner, wherein a space arranged between the pressurizing tank and the water injection box is closed along with the rising of the pressure in the pressurizing tank, and the pressurizing tank and the water injection box are opened along with the falling of the pressure in the pressurizing tank. The invention has the following effects: according to the washing machine of the embodiment, the cleaning effect of the fine bubble water containing fine bubbles can be improved, and the number of parts can be reduced to ensure the assembling workability of the washing machine.
