Embodiment Construction

[0023] In order to make the purpose, technical solution, and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] see Figure 1 to Figure 6 As shown, the present invention is an integrated heat pump 100. The integrated heat pump 100 integrates the driving device 1 and the heating assembly 2 to save space, and can be conveniently installed in household appliances, such as dishwashers and washing machines. Inside.

[0025] The integrated heat pump 100 is provided with a cocoon-shaped pump casing 3, the driving device 1 installed in the pump casing 3, and the impeller 4 installed in the pump casing 3 and connected to the driving device 1 in transmission. . The pump casing 3 is provided with an open accommodation cavity 30, and an outwardly protruding rib 31 is provided on the outer peripheral edge of one end of the accommodation cavity of the pump cas...

Abstract

An integrated heat pump comprises a pump casing, a driving device installed in the pump casing, an impeller installed in the pump casing and connected in transmission with the driving device, and a heater arranged opposite to the impeller. A cavity for accommodating medium is formed between the heater and the impeller, and the integrated heat pump is also provided with an input pipe, an output pipe, and a heating assembly communicating with the cavity, and the heating assembly includes the The heater and a casing shielding the outside of the heater, the casing is snap-fitted connected with the pump casing to cover the heater in the casing. In this way, the heater is not easy to accumulate dust, and the service life of the heater is prolonged.

Description

technical field [0001] The invention relates to a heat pump required in the field of household appliances, in particular to an integrated heat pump with a protection device. Background technique [0002] In the field of dishwashers and washing machines, both heating systems and centrifugal pump systems are used. Both systems require a certain amount of space and assembly methods to work in harmony. Therefore, the dishwasher needs to reserve a large space for the two systems of the centrifugal pump and the heater, and thus consumes more water and energy. [0003] At present, the main methods on the market are: 1. The centrifugal pump is arranged separately from the heating plate. 2. Integrated heating is adopted, but there is no protection design and the design of the heater is different. One of the two ways occupies a large space, and the other has a low safety factor. [0004] Therefore, it is necessary to design an improved integrated heat pump to solve the above probl...
