So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.

In the description herein, unless otherwise specified and limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may include, for example, mechanical or electrical connections, communications between two elements, direct connections, and indirect connections via intermediary media, where the specific meaning of the terms is understood by those skilled in the art as appropriate.
The embodiment of the present disclosure provides a household electrical appliance, including evaporimeter, condenser, still include: the third heat exchanger comprises a first refrigerant flow path and a second refrigerant flow path which are arranged in a staggered manner; the first refrigerant flow path is communicated with a refrigerant outlet of the evaporator; the second refrigerant flow path is communicated with a refrigerant outlet of the condenser.
It is to be understood that the evaporator herein may be referred to as a first heat exchanger and the condenser herein may be referred to as a second heat exchanger. The household appliance provided by the embodiment of the disclosure further comprises a third heat exchanger. The refrigerant flowing out of the refrigerant outlet of the evaporator is defined as a first refrigerant, and the refrigerant flowing out of the refrigerant outlet of the condenser is defined as a second refrigerant. The first refrigerant flow path of the third heat exchanger is communicated with the refrigerant outlet of the evaporator, the second refrigerant flow path is communicated with the refrigerant outlet of the condenser, and the first refrigerant flow path and the second refrigerant flow path are arranged in a staggered mode to exchange heat of the first refrigerant in the first refrigerant flow path and the second refrigerant in the second refrigerant flow path, so that the temperature difference between the refrigerant entering the evaporator and the condenser and the external temperature is increased, the heat exchange efficiency of the evaporator and the condenser is improved, and the refrigeration or heating efficiency of the household appliance is improved.
As can be seen from the heat transfer formula Φ — kA Δ T, the greater the temperature difference between the evaporator and the condenser, the higher the heat transfer efficiency, and the more heat can be transferred per unit time. Therefore, the larger the temperature difference between the refrigerant entering the evaporator or the condenser and the outside is, the higher the heat exchange efficiency of the evaporator or the condenser is.
Taking the refrigeration condition as an example, as shown in fig. 2, the refrigerant flowing into the evaporator 1 is obtained by flowing out of the condenser 2 and throttling and depressurizing the refrigerant through the capillary tube 4, and if the temperature of the second refrigerant flowing out of the condenser 2 is lowered, the temperature of the refrigerant flowing into the evaporator 1 can be lowered. The temperature of the refrigerant flowing into the condenser 2 is obtained by the evaporator 1 flowing out and applying work through the compressor 3, and the temperature of the refrigerant flowing into the condenser 2 can be increased by increasing the temperature of the first refrigerant flowing out of the evaporator 1. Taking a window type air conditioner as an example, the window type air conditioner concentrates an evaporator 1 and a condenser 2 in the same box, the temperature of a first refrigerant flowing out of the evaporator 1 is usually about 15 ℃, and the temperature of a second refrigerant flowing out of the condenser 2 is usually about 45 ℃. As shown in fig. 1, in the present application, the third heat exchanger 5 exchanges heat between the first refrigerant in the first refrigerant flow path and the second refrigerant in the second refrigerant flow path, and after exchanging heat between the first refrigerant with a lower temperature and the second refrigerant with a higher temperature, the temperature of the first refrigerant is increased, and the temperature of the second refrigerant is decreased, so that the temperature difference between the refrigerant of the evaporator 1 and the condenser 2 and the outside is increased, and the heat exchange efficiency of the evaporator 1 and the condenser 2 is increased.
The first refrigerant flow path and the second refrigerant flow path which are arranged in a staggered manner can be understood as that the first refrigerant flow path and the second refrigerant flow path can be arranged in a staggered manner, so that the purpose of exchanging heat between the first refrigerant in the first refrigerant flow path and the second refrigerant in the second refrigerant flow path is achieved. Alternatively, the "staggered arrangement" may be that the first refrigerant flow path and the second refrigerant flow path include at least one contact point, that is, heat exchange may be performed in a direct contact manner, for example, heat exchange between the first refrigerant and the second refrigerant is achieved by a method of arranging cross contact and mutual winding, winding the first refrigerant flow path around the outer surface of the second refrigerant flow path, winding the second refrigerant flow path around the outer surface of the first refrigerant flow path, passing the first refrigerant flow path through the second refrigerant flow path, or passing the second refrigerant flow path through the first refrigerant flow path.
Optionally, an inner diameter of the first refrigerant flow path is larger than an inner diameter of the second refrigerant flow path. For example, when the air conditioner operates under a cooling condition, the state of the first refrigerant flowing out of the evaporator 1 is gaseous, the state of the second refrigerant flowing out of the condenser 2 is liquid, and the inner diameter of the first refrigerant flow path is set to be larger than that of the second refrigerant flow path, so that heat exchange between the refrigerants in the two refrigerant flow paths can be better realized. Optionally, a ratio of an inner diameter of the first refrigerant flow path to an inner diameter of the second refrigerant flow path is 1.5-5: 1.
Optionally, the third heat exchanger comprises: a housing forming a first refrigerant flow path; the pipeline penetrates through the shell and forms a second refrigerant flow path.
As shown in fig. 3 to 5, the second refrigerant flow path 52 penetrates the housing 510 forming the first refrigerant flow path 51 to exchange heat between the first refrigerant and the second refrigerant. Taking the cooling operation as an example, the first refrigerant having a relatively low temperature enters the first refrigerant flow path 51 of the third heat exchanger 5, and the second refrigerant flow path 52 penetrates the casing 510 to exchange heat with the first refrigerant in the casing 510. Alternatively, the material of the second refrigerant flow path 52 may be the same as that of the refrigerant outflow pipeline of the condenser; alternatively, the second refrigerant passage 52 is a partial pipe section of a refrigerant outflow line of the condenser.
Alternatively, when the second refrigerant passage 52 is a partial pipe section of the refrigerant outflow line of the condenser, the housing 510 constituting the first refrigerant passage 51 is provided with 4 openings. The first opening can be used as an inlet of a first refrigerant, and the second opening can be used as an outlet of the first refrigerant; the second refrigerant passage 52 in a pipe shape penetrates the remaining two openings of the housing 510. Optionally, the pipe is sealingly connected to the remaining two openings in a realisable manner, which may be by welding, gluing, etc.
Alternatively, the third heat exchanger 5 includes a first refrigerant passage 51 and a second refrigerant passage 52 that are integrally formed. For example, the second refrigerant passage 52 having a small inner diameter and a pipe shape is provided in the housing 510 constituting the first refrigerant passage 51, as shown in fig. 3 to 5. At this time, the housing 510 is provided with 4 openings, wherein the first opening may serve as an inlet of the first refrigerant, and the second opening may serve as an outlet of the first refrigerant; the remaining two openings are formed by penetrating both ends of the second refrigerant passage 52 through the casing 510, and serve as an inlet and an outlet of the second refrigerant, respectively. The integrally formed third heat exchanger 5 can improve the sealing property of the third heat exchanger 5.
Optionally, the housing comprises a heat exchange chamber and the conduit comprises a heat exchange tube section, the heat exchange tube section being disposed within the heat exchange chamber.
The heat exchange cavity may serve as the first refrigerant flow path 51, and the pipeline includes a heat exchange pipe section disposed in the heat exchange cavity. For example, when the air conditioner operates under a cooling condition, a gaseous first refrigerant flowing out of the evaporator 1 enters the heat exchange cavity and fills the heat exchange cavity, a second refrigerant flowing out of the condenser flows in the heat exchange tube section arranged in the heat exchange cavity, the first refrigerant and the second refrigerant complete heat exchange in the heat exchange cavity, the first refrigerant with lower temperature performs a cooling function on the second refrigerant with higher temperature, the second refrigerant with higher temperature performs a heating function on the first refrigerant with lower temperature, the temperature of the first refrigerant is further improved, and the temperature of the second refrigerant is reduced. Alternatively, the term "housing comprising a heat exchange chamber" is understood here to mean: the housing 510 constitutes a heat exchange chamber. Optionally, the material of the housing 510 is metal, such as copper, aluminum or aluminum alloy.
Alternatively, the heat exchange tube segments are helical, as shown in FIG. 3.
The spiral heat exchange tube segment improves the length of the heat exchange tube segment, improves the contact area between the heat exchange tube segment and the first refrigerant in the shell 510, improves the heat exchange efficiency between the first refrigerant in the first refrigerant flow path 51 and the second refrigerant in the second refrigerant flow path 52, and improves the refrigerating or heating capacity of the household appliance.
Alternatively, the heat exchange tube segments are convoluted, as shown in FIG. 4.
The convoluted heat exchange tube segment improves the length of the heat exchange tube segment, improves the contact area between the heat exchange tube segment and the first refrigerant in the shell 510, improves the heat exchange efficiency between the first refrigerant in the first refrigerant flow path 51 and the second refrigerant in the second refrigerant flow path 52, and improves the refrigerating or heating capacity of the household appliance.
Alternatively, the heat exchange tube segments are linear, as shown in FIG. 5.
The linear heat exchange pipe section can utilize a refrigerant outflow pipeline of a condenser of the household appliance device as the heat exchange pipe section, the refrigerant pipeline of the outflow part of the existing condenser can not be improved, and the preparation process of the third heat exchanger 5 provided by the embodiment of the disclosure is simplified.
Optionally, the household electrical appliance further includes a compressor, and the first refrigerant flow path includes: the first inlet is communicated with a refrigerant outlet of the evaporator; a first outlet in communication with the inlet of the compressor.
The first refrigerant flow path 51 includes a first inlet 511 communicating with the refrigerant outlet of the evaporator 1 and a first outlet 512 communicating with the inlet of the compressor 3, where communication can be understood as direct communication, as shown in fig. 3-5. The first refrigerant passage 51 exchanges heat of the first refrigerant flowing out of the evaporator 1 in the third heat exchanger 5, and the first refrigerant having exchanged heat flows out of the first outlet 512, flows into the compressor, and then flows into the condenser 2. Taking the refrigeration working condition as an example, after the first refrigerant exchanges heat through the third heat exchanger 5, the temperature is raised, that is, the temperature of the refrigerant flowing into the condenser 2 is raised, and the heat exchange efficiency of the condenser 2 of the household appliance is improved.
Optionally, the second refrigerant flow path includes: the second inlet is communicated with the refrigerant outlet of the condenser; and the second outlet is communicated with the refrigerant inlet of the evaporator.
The second refrigerant flow path 52 includes a second inlet 521 communicating with the refrigerant outlet of the condenser and a second outlet 522 communicating with the refrigerant inlet of the evaporator, where communication is understood to be direct communication, as shown in fig. 3-5. The second refrigerant passage 52 exchanges heat of the second refrigerant flowing out of the condenser 2 in the third heat exchanger 5, and the second refrigerant having exchanged heat flows out through the second outlet 522 and enters the evaporator 1 through the capillary tube 4. Taking the refrigeration condition as an example, after the second refrigerant exchanges heat through the third heat exchanger 5, the temperature is reduced, that is, the temperature of the refrigerant flowing into the evaporator 1 is reduced, and the heat exchange efficiency of the evaporator 1 of the household appliance is improved.
Optionally, the household appliances include window air conditioners, refrigerators, and freezers.
The household appliance provided by the embodiment of the disclosure can be a window type air conditioner. The evaporator 1 and the condenser 2 of the window type air conditioner are arranged in the same box body, a refrigerant flow path of the evaporator 1 and a refrigerant flow path of the condenser 2 can be easily guided together, the cost is low, and the window type air conditioner is beneficial to improving the refrigerating or heating efficiency of the window type air conditioner by arranging the third heat exchanger 5. And the length of the pipeline which needs to be increased and is additionally provided with the third heat exchanger is shorter, and the generated pressure drop has little influence on the performance of the window type air conditioner.
The household appliance provided by the embodiment of the disclosure can also be a refrigerator, a freezer and other refrigeration equipment, and can be used for improving the refrigeration capacity of the refrigerator, the freezer and other refrigeration equipment.
