Abstract: The present invention discloses a dehumidifier, a compressor and dehumidifier control method. A terminal cover is arranged at the top of the compressor, a mounting base and a wire outlet seat are arranged on the terminal cover, the mounting base is provided with a fixing groove used for mounting a first temperature detecting device for detecting the temperature at the top of the compressor, a bottom opening communicated with the top of the compressor is arranged at the bottom end of the fixing groove used for enabling the first temperature detecting device to prop against the top of the compressor and detect the temperature at the top of the compressor; the wire outlet seat is provided with a wiring groove used for mounting connecting wires of the compressor, and a clamping slot used for mounting a second temperature detecting device for detecting the temperature of the connecting wires.

Abstract: An amphoteric betaine-type polycarboxylic acid water reducer and a preparation method therefor are provided in the present invention. An unsaturated betaine-type monomer A and an acrylic acid-type polyethylene glycol monomer B are placed in a reaction container, stirred until uniform and then an acrylic acid-type monomer C is added, the stirring is continued and water is added to make adjustments so as to make the total mass of the monomers account for 10%-20% of the total mass of the aqueous solution; and under the protection of an inert gas, the temperature is raised to 60° C.-100° C., an aqueous initiator solution is added, maintaining the temperature and reacting for 4-6 h, and after the reaction is completed, the solution is cooled to room temperature, and the pH value thereof is adjusted to 5-7 to prepare the amphoteric betaine-type polycarboxylic acid water reducer.
