According to some embodiments of the present invention, as shown in fig. 2 and 7, groove 213 includes a first groove segment 2131 and a second groove segment 2132. The first recessed section 2131 extends in the axial direction of the housing 11. One end of the second recessed segment 2132 is connected to the first recessed segment 2131 and the other end of the second recessed segment 2132 extends in a direction toward the center of the enclosure 11. The protrusion 214 includes a first protrusion section 2141 and a second protrusion section 2142. The first protruding section 2141 extends in the axial direction of the cabinet 11, and the first protruding section 2141 fits in the first recessed section 2131. One end of the second protruding section 2142 is connected to the first protruding section 2141, the other end of the second protruding section 2142 extends in a direction toward the center of the cabinet 11, and the second protruding section 2142 fits into the second recessed section 2132.

For example, in the example of fig. 2 and 5, the second groove segment 2132 extends in a horizontal direction away from the first groove segment 2131, where the grooves 213 are generally L-shaped in shape. Similarly, the second protrusion 2142 extends in a direction away from the first protrusion 2141 along the horizontal direction, and the protrusion 214 is substantially L-shaped, so that when the protrusion 214 is inserted into the groove 213, the groove 213 and the protrusion 214 can achieve a simple labyrinth seal, so that external water is difficult to infiltrate into the housing 21, and the waterproof effect of the heat pump water heater 100 is further enhanced.

Further, the heat pump water heater 100 further includes a top cover 3, the top cover 3 is covered on the top of the housing 21, and the bottom wall of the top cover 3 abuts against the outer sidewall of the second groove section 2132.
