[0092] Although not shown, the second door (31) may further include all or part of the same configuration as the first door shelf (313) and first shelf support (314) of the first door (32).

[0093] FIG. 2 is an exploded perspective view showing the internal configuration of a machine room of a refrigerator among home appliances according to one embodiment.

[0094] Fig. 2 shows the internal configuration of the machine room separated from the rear of the refrigerator (1) of Fig. 1.

[0095] Referring to Fig. 2, a machine room (40) may be provided at the lower rear side of the main body (10). However, the location of the machine room (40) is not limited thereto.

[0096] According to one embodiment, the machine room (40) may form a space in which a plurality of electrical components constituting a refrigeration cycle for cooling a storage room (e.g., the storage room (20) of FIG. 1) are arranged. The machine room (40) may be, for example, partitioned from the storage room (20) to form an independent space. The machine room (40) may be, for example, formed to be connected to an external space so that at least a portion of the components inside the machine room (40) may exchange heat with the outside.

[0097] According to one embodiment, the machine room (40) may include an upper plate (41), a lower plate (42), a side plate (43), or a rear cover (44). The upper plate (41) may, for example, form an upper surface of the machine room (40). The lower plate (42) may, for example, form a bottom surface of the machine room (40). The lower plate (42) may, for example, be provided to support electrical components (e.g., a compressor (51), a condenser (52), a blower (60)) disposed inside the machine room (40). The side plates (43) may, for example, form both sides of the machine room (40). The rear cover (44) may, for example, form the rear surface of the machine room (40). The rear cover (44) may, for example, be positioned on the same plane as the rear surface of the main body (10). That is, the rear cover (44) can form a part of the exterior of the refrigerator (1). The rear cover (44) can prevent the components inside the machine room (40) from being visible from the outside. The rear cover (44) can be detachably mounted, for example, on the lower rear side of the main body (10). Accordingly, a user can detach the components placed inside the machine room (40) by detaching the rear cover (44).

[0098] According to one embodiment, the rear cover (44) may include a first through hole (441) (e.g., an inlet) or a second through hole (442) (e.g., an outlet). The first through hole (441) may be, for example, a hole formed to allow air from outside the refrigerator (1) to flow into the inside of the machine room (40). The second through hole (442) may be, for example, a hole formed to allow air from inside the machine room (40) to flow out to the outside. Since the compressor (51) and the condenser (52) inside the machine room (40) emit heat while compressing or condensing the refrigerant, the temperature of the air inside the machine room (40) may increase. The first through hole (441) and the second through hole (442) may circulate the air inside the machine room (40). Specifically, cold air from outside can be introduced through the first through hole (441), and heated air inside the machine room (40) can be discharged to the outside through the second through hole (442).

[0099] According to some embodiments, a through hole may also be formed in the lower plate (42) or the side plate (43) to allow air to circulate inside the machine room (40).

[0100] According to one embodiment, the cold air supply device (50) (or heat pump) may include a compressor (51), a condenser (52), an expansion valve (not shown), or an evaporator (not shown). The cold air supply device (50) may operate a refrigeration cycle using, for example, the compressor (51), the condenser (52), the expansion valve, and the evaporator, thereby generating cold air to be provided to the storage compartment (20).

[0101] According to one embodiment, the compressor (51) may be disposed within the machine room (40). The compressor (51) may, for example, compress the refrigerant to a high temperature and high pressure state. Specifically, the compressor (51) may receive electric energy from the outside and use the rotational force of a motor (e.g., the motor (341) of FIG. 3) to compress the gaseous refrigerant to a high temperature and high pressure state. The compressed refrigerant may be moved to the condenser (52) by the connecting pipe (53). The compressor (51) may, for example, be disposed adjacent to the second through hole (442).

[0102] According to one embodiment, the condenser (52) may be disposed within the machine room (40). The condenser (52) may, for example, condense compressed refrigerant received from the compressor (51). The condenser (52) may radiate heat generated while condensing the refrigerant to the outside of the condenser (52). The condensed refrigerant passing through the condenser (52) may be moved to the expansion valve. The condenser (52) may, for example, be disposed adjacent to the first through hole (441).

[0103] The condensed refrigerant can become a low-temperature, low-pressure liquid as it passes through the expansion valve. The liquid refrigerant can pass through the expansion valve and move to the evaporator. The evaporator can vaporize the liquid refrigerant. As the liquid refrigerant evaporates, heat exchange occurs with the surrounding gas. As the liquid refrigerant evaporates, it absorbs latent heat from the surroundings, and as a result, the gas surrounding the evaporator is cooled, generating cold air. The generated cold air can be moved to the storage chamber (20) through a passage provided between the outer housing (11) and the inner housing (12). The vaporized refrigerant can be moved again to the compressor (51).

[0104] In one embodiment, a blower (60) may be disposed between a compressor (51) and a condenser (52) within a machine room (40). The blower (60) may be disposed, for example, such that air within the machine room (40) flows from the condenser (52) toward the compressor (51). The blower (60) may be mounted, for example, directly or indirectly, to a lower plate (42).

[0105] According to one embodiment, a drain hose (70) may be placed inside the machine room (40). The drain hose (70) may guide defrost water generated in the storage room (20) or the like to move to the machine room (40). Defrost water generated in the refrigerator (1) may move to the bottom surface of the machine room (40), i.e., the lower plate (42), through the drain hose (70). A fixing member (521) may be provided on the lower plate (42) to prevent water moved to the bottom surface from coming into contact with the condenser (52). The fixing member (521) may be formed to surround, for example, a portion of the lower portion of the condenser.

The converter (321) may electrically connect the power supply unit (310) and the inverter (323). The converter (321) may rectify AC power supplied from the power supply unit (310) and output a rectifying link voltage. For example, the converter (321) may be configured as a diode half-wave rectifier circuit to convert the AC power supplied from the power supply unit (310) into DC power by half-wave rectifying it. In addition, the converter (321) may full-wave rectify AC power by connecting four switching elements (Q1, Q2, Q3, Q4) in a high bridge configuration as illustrated instead of conventional diodes. The structure of the switching elements of the converter (321) is exemplary and does not limit the scope of the present disclosure.

[0117] According to one embodiment, a smoothing capacitor (322) may be connected between the converter (321) and the inverter (323). The smoothing capacitor (322) may smooth the voltage output from the converter (321) and convert it into direct current.

[0118] According to one embodiment, the inverter (323) may be configured to convert the DC voltage output from the converter (321) or the smoothing capacitor (322) into a three-phase AC (U, V, W) in the form of pulses with an arbitrary variable frequency through pulse width modulation (PWM).

The chip inductor (334) may be seated or coupled through the open portion of the chip inductor receiving portion (331). The chip inductor receiving portion (331) may constitute a portion of the main body (330a). The connector (330) structure of the present disclosure forms the chip inductor receiving portion (331) with an open upper portion during the manufacturing process of the connector (330), thereby facilitating the assembly of chip inductors (334) having different specifications as needed.

[0130] According to one embodiment, the chip inductor receiving portion (331) may include a bottom portion (3311), a first partition wall (3312), and a second partition wall (3313).

The second pin (333) may penetrate the second bulkhead (3313) and a portion thereof may be introduced into the second groove (3302).

[0150] According to one embodiment, the first connection end (3321) and the second connection end (3331) may be positioned to face each other while being spaced apart from each other. The first connection end (3321) and the second connection end (3331) facing each other may be coupled to a single chip inductor (334).

One first pin (332) and one second pin (333) corresponding to each other among the first pin (332) and the second pin (333) may be arranged so as to overlap along the longitudinal direction. For example, the first pin (332) and the second pin (333) facing each other may be positioned on a straight line.

[0152] In one embodiment, the chip inductor (334) can be coupled to be electrically connected to the first pin and the second pin (333). One chip inductor (334) can be electrically connected to one first pin (332) and one second pin (333). Before the chip inductor (334) is electrically connected to the first pin (332) and the second pin (333), no voltage and / or current is transmitted between the first pin (332) and the second pin (333).

[0153] According to one embodiment, the number of chip inductors (334) may be provided to correspond to the number of first pins (332) or the number of second pins (333). For example, if the number of first pins (332) or second pins (333) is three as illustrated, three chip inductors (334) may be provided.

[0155] According to one embodiment, the chip inductor (334) may include a first terminal (3341) and a second terminal (3342). The first terminal (3341) and the second terminal (3342) may be disposed on one surface of the chip inductor (334). The first terminal (3341) may be connected to the first pin (332). For example, the first terminal (3341) may be connected to the first connection end (3321). The second terminal (3342) may be connected to the second pin (333). For example, the second terminal (3342) may be connected to the second connection end (3331).

[0156] According to one embodiment, the chip inductor (334) may be disposed above the first connection end (3321) and the second connection end (3331) (e.g., in the +z direction). The chip inductor (334) may be soldered to the first connection end (3321) and the second connection end (3331). The chip inductor (334) may be disposed between the first partition wall (3312) and the second partition wall (3313). At least one of the first partition wall (3312) and the second partition wall (3313) may be formed to protrude above the chip inductor (334) (e.g., in the +z direction). The method by which the chip inductor (334) is connected to the first pin (332) and the second pin (333) is not limited thereto, and in addition to soldering, the electrodes and pins (the first pin, the second pin) may be electrically connected to each other by a method such as simple contact or fitting connection.

[0157] According to one embodiment, a connector (330) includes a chip inductor (334), thereby filtering out noise between wires (e.g., common mode noise), such as an inverter motor (341). Typically, a ferrite core or a CM choke coil has been used to filter out such noise, but this has resulted in problems of requiring additional manufacturing processes and taking up additional space. The present disclosure provides a filter in the connector (330), thereby minimizing the area occupied by the product within a home appliance and simplifying the manufacturing process, thereby reducing manufacturing costs.

[0158] According to one embodiment, a connector (330) can secure sufficient filter accommodation space (3314) to improve the manufacturing difficulty of electrically connecting a chip inductor (334) to a first connection end (3321) and a second connection end (3331).

[0159] Figure 8 is a cross-sectional view of the connector taken along line AA of Figure 5.

[0160] The embodiment of Fig. 8 can be optionally combined with the embodiments of Figs. 1 to 7. The embodiment of Fig. 8 can be optionally combined with the embodiments of Figs. 9 to 17.

[0161] Referring to FIG. 8, the second protrusion (336) formed between two adjacent chip inductors (334) can increase the surface distance (or creepage distance) between the two chip inductors (334). Even if the distance between the two chip inductors (334) becomes shorter due to the formation of the second protrusion (336), the occurrence of a short circuit between the two adjacent chip inductors (334) in situations such as high voltage output can be prevented. By forming the second protrusion (336), a compact-sized connector (330) can be implemented even though the chip inductor (334) is additionally placed on the connector (330).

[0162] According to one embodiment, the second protrusion (336) and the chip inductor (334) may be spaced apart from each other. By providing a gap between the second protrusion (336) and the chip inductor (334), sufficient mounting space can be secured when the chip inductor (334) is mounted in the filter receiving space (3314) during the manufacturing step.

[0163] According to one embodiment, the chip inductor (334) may be in contact with the first protrusion (335). The chip inductor (334) may be supported by the first protrusion (335). However, this is not limited thereto, and unlike the drawing, the chip inductor (334) may be soldered to the first connection end (e.g., the first connection end (3321) of FIG. 6) and the second connection end (e.g., the second connection end (3331) of FIG. 6) while being spaced apart from the first protrusion (335).

[0165] The embodiment of Fig. 9 can be optionally combined with the embodiments of Figs. 1 to 8. The embodiment of Fig. 9 can be optionally combined with the embodiments of Figs. 10 to 17.

[0166] Referring to FIG. 9, according to one embodiment, the first protrusion (335) may be formed to protrude further upward than the first upper surface (332a) of the first pin (332) or the second upper surface (333a) of the second pin (333). The first protrusion (335) may serve as a barrier to prevent the solder paste applied on the first connection end (3321) of the first pin (332) and the solder paste applied on the second connection end (3331) of the second pin (333) from being combined with each other during the soldering process.

[0167] However, this is not limited thereto, and the first protrusion (335) may be omitted from the connector (330). That is, the bottom portion (3311) may be positioned on the same plane as the first upper surface (332a) of the first pin (332) and the second upper surface (333a) of the second pin (333).

[0168] In one embodiment, the first inner side surface (3312a) of the first bulkhead (3312) may be an inclined surface. In one embodiment, the second inner side surface (3313a) of the second bulkhead (3313) may be an inclined surface. The first inner side surface (3312a) and the second inner side surface (3313a) may be formed as inclined surfaces such that the width of the filter receiving space (3314) becomes narrower as it goes toward the bottom portion (3311).

[0169] In one embodiment, the first bulkhead (3312) may include a first through hole (3312b). The first through hole (3312b) may be formed such that a first pin (332) may pass through it. The first pin (332) may pass through the first through hole (3312b) and enter the first groove (3301). The first pin (332) may enter the first groove (3301) until it contacts the side surface of the first protrusion (335).

[0170] In one embodiment, the first bulkhead (3312) may include a second through hole (3313b). The second through hole (3313b) may be formed such that a second pin (333) may pass through it. The second pin (333) may pass through the second through hole (3313b) and enter the second groove (3302). The second pin (333) may enter the second groove (3302) until it contacts the side surface of the first protrusion (335).

[0172] The embodiment of Fig. 10 can be optionally combined with the embodiments of Figs. 1 to 9. The embodiment of Fig. 10 can be optionally combined with the embodiments of Figs. 11 to 17.

[0173] Among the configurations of the connector (1000) illustrated in FIG. 10, the same reference numbers are used for configurations that are substantially the same or similar to the configurations of the connector (330) described in FIGS. 4 to 9.

[0174] Referring to FIG. 10, according to one embodiment, the connector (1000) may include a first pin (1010) and a second pin (1020).

[0175] According to one embodiment, the first pin (1010) may include a first load portion (1011) and a first connection end portion (1012). The first load portion (1011) may have, for example, a straight shape. The first connection end portion (1012) may be formed at an end of the first load portion (1011) toward the second pin (1020). The first connection end portion (1012) may have a larger horizontal cross-sectional area than the first load portion (1011). For example, the first connection end portion (1012) may have a larger width than the first load portion (1011). Here, the width may be a value measured with respect to a direction perpendicular to the longitudinal direction of the first pin (1010) (e.g., the x-axis direction). For example, the first pin (1010) may have a 'T' cross-sectional shape.

[0176] According to one embodiment, the second pin (1020) may include a second load portion (1021) and a second connection end portion (1022). The second load portion (1021) may have, for example, a straight shape. The second connection end portion (1022) may be formed at an end of the second load portion (1021) toward the second pin (1020). The second connection end portion (1022) may have a larger horizontal cross-sectional area than the second load portion (1021). For example, the second connection end portion (1022) may have a larger width than the second load portion (1021). Here, the width may be a value measured with respect to a direction perpendicular to the longitudinal direction of the second pin (1020) (e.g., the x-axis direction). For example, the second pin (1020) may have a 'T' cross-sectional shape.

[0177] According to one embodiment, the cross-sectional shape of the first connection end (1012) may correspond to the cross-sectional shape of the first electrode (e.g., the first electrode (3341) of FIG. 7) of the chip inductor (e.g., the chip inductor (334) of FIG. 7). As an example, the first connection end (1012) may have a rectangular cross-section, but is not limited thereto.

[0178] In one embodiment, the cross-sectional shape of the second connection end (1022) may correspond to the cross-sectional shape of the second electrode of the chip inductor (334) (e.g., the second electrode (3342) of FIG. 7). As an example, the first connection end (1012) may have a rectangular cross-section, but is not limited thereto.

[0179] As shown, by having the first connection end (1012) and the second connection end (1022) having a shape having a large area in the first pin (1010) and the second pin (1020), the first pin (1010) and the second pin (1020) can be electrically firmly coupled to the chip inductor (334).

[0180] In one embodiment, the connector (1000) may include a chip inductor, which may be substantially identical to the chip inductor (334) of FIG. 7. One chip inductor may be soldered to one first connection end (1012) and one second connection end (1022).
