Description

Indoor unit of air conditioner and air conditioner Technical Field The utility model relates to the technical field of air conditioners, in particular to an air conditioner indoor unit and an air conditioner. Background With the development of the air conditioning and refrigeration industry, people favor the application of environment-friendly refrigerants. For example, R290 refrigerant, which contains propane as the main component, is an extremely flammable and explosive refrigerant, but has ozone depletion potential (Ozone Depletion Potential, ODP) of 0, no fluorine, and extremely low global warming potential (Global Warming Potential, GWP), and is an environmentally friendly refrigerant. When the R290, which is environmentally friendly but flammable and explosive, is applied to an air conditioner, it is necessary to strictly control the concentration thereof in order to prevent the explosion phenomenon. At present, the industry generally adopts a detection alarm mode to remind a user that the concentration of the refrigerant exceeds the standard, ventilation is needed, the mode has feasibility for the refrigerant with small common hazard (such as R32), but the mode still has a larger safety risk for the flammable and explosive refrigerant. Therefore, how to reduce the safety risk caused by refrigerant leakage is an urgent problem to be solved in the industry. Disclosure of utility model The utility model provides an air conditioner indoor unit and an air conditioner, which are used for solving the problem that the safety risk is higher in the prior art by adopting a detection alarm mode to cope with refrigerant leakage. A first aspect of the present utility model provides an indoor unit of an air conditioner, including: the indoor unit body is internally provided with an installation cavity; A safety protection assembly, in which a discharge passage is formed; the discharge channel is provided with a conducting state and a cut-off state, one end of the safety protection component is arranged on the indoor unit body, the other end of the safety protection component extends to the outside, and the safety protection component is used for discharging the refrigerant leaked into the installation cavity to the outside in the conducting state. The indoor unit of the air conditioner provided by the utility model further comprises: The detection assembly is used for detecting the content of the refrigerant in the installation cavity; and the control assembly is electrically connected with the detection assembly and the safety protection assembly. According to the air conditioner indoor unit provided by the utility model, the safety protection assembly comprises: one end of the discharge pipe is communicated with the mounting cavity, and the other end of the discharge pipe extends to the outside of the room; and a first switch member mounted on the discharge pipe for switching the discharge passage between the on state and the off state. According to the air conditioner indoor unit provided by the utility model, the indoor unit body is also provided with the exhaust port, the exhaust port is communicated with the mounting cavity, and the safety protection assembly further comprises: The connecting piece is arranged at the exhaust port and is detachably connected with one end of the exhaust pipe.
