According to data from Qichacha, Haier Zhijia (600690) has obtained a new invention patent authorization, titled "A Gas Detection Device for Washing Machines", with patent application number CN201910656401.5 and authorization date of June 21, 2024.
Patent Abstract: The present invention relates to the technical field of washing machines and discloses a gas detection device for washing machines. The gas detection device is configured to be installed in the sink of the washing machine. The gas detection device includes a shell and a gas detection component, and the shell can be installed in the sink; The gas detection component is installed inside the shell, and corresponds to the outlet of the flow channel of the washing machine. Gas is introduced into the flow channel, and the gas detection component receives the gas flowing out from the outlet and rotates to detect the water inlet program of the washing machine's water tank. Before leaving the factory, the gas detection device is installed in the sink of the washing machine, and gas is introduced into the flow channel. When the gas flows to the gas detection component at the outlet of the flow channel, the gas detection component acts, proving that the water inlet program of the flow channel is running correctly. The setting of the gas detection device replaces the water detection method through gas detection, keeping the washing machine in a dry state without the need for wiping, saving production and labor costs.
