Temperature-adjustable bed

The invention provides a temperature-adjustable bed. The bed comprises a plurality of supporting legs, a bed board and fences. The fences are arranged on at least three side faces of the bed board ina surrounding mode. The supporting legs are cylindrical. The bed further comprises a temperature control assembly. Sliding grooves are formed in the supporting legs in the axial direction of the supporting legs. The bed board is slidably connected into the sliding grooves through connecting assemblies. The temperature control assembly comprises a water tank, a circulating water pipe and a heat exchanger. The circulating water pipe communicates with the water tank. The water tank is arranged on one sides of the supporting legs. The circulating water pipe is laid below the bed board. The heat exchanger is arranged between the water tank and the circulating water pipe. When the temperature-adjustable bed is used as a baby crib or a nursing bed, the bed board can be adjusted to be at the sameheight as or at a proper height as an adult bed. Therefore, parents can conveniently take care of infants, or nursing workers can conveniently take care of patients or old people. The circulating water pipe, the water tank and the heat exchanger are laid below the bed board, so that the bed board is preheated or cooled. Various use requirements are met.
