Patent Description:
The compressor is an important part of an air conditioner, and provides compression and driving of a refrigerant in a refrigerant loop. Usually, the compressor is mounted in an outdoor unit of the air conditioner. The compressor extracts the refrigerant from a low-pressure region, compresses the refrigerant, and conveys the refrigerant to a condenser. Heat is dissipated through the condenser, causing the refrigerant to change from a gaseous state to a liquid state.

In the related art, a temperature sensor is disposed on a compressor of an outdoor units of some the air conditioner. However, due to a weak mounting structure of the temperature sensor, the temperature sensor comes loose easily, leading to distortion of detected temperature data. In this way, when an electronic control system of the air conditioner controls the compressor based on the temperature data detected by the temperature sensor, a protection action may fail to be made in time, resulting in failures such as wear of a pump body of the compressor and demagnetization of a motor. <CIT> discloses a compressor and an air conditioner.

The side plates on the two sides exert pressure on the temperature sensor from the two sides. In addition, the opening slot is formed on the top plate to increase elasticity to allow the top plate to press against the temperature sensor, which enables the temperature sensor to remain in contact with the outer wall of the housing, eliminating defects of the temperature sensor being looseness and falling off. The temperature sensor can effectively detect the housing temperature of the compressor, which helps to precisely control an operation state of the compressor.

The air conditioner is an air regulator, which is a device that uses artificial means to regulate and control the temperature, humidity, flow rate, and other parameters of ambient air in a building. Generally, the air conditioner comprises several parts of a cold source/heat source device, a hot and cold medium distribution system, and an end device, and other auxiliary devices. A refrigeration host, a water pump, a fan, and a piping system are mainly comprised. The end device is responsible for dealing with a state of the air as desired using distributed cold and heat, to achieve a determined target of an air parameter of a target environment.

In the related art, most air conditioners use a compressor as a power source for a refrigerant. The compressor is a fluid machine that changes a low-pressure gas into a high-pressure gas. The compressor is configured to take in a low-temperature and low-pressure refrigerant gas from a suction pipe, compress the low-temperature and low-pressure refrigerant gas to output a high-temperature and high-pressure refrigerant gas, and further provide power for a circulation of the refrigerant, realizing a refrigeration cycle of compression→condensation (heat release)→expansion→evaporation (heat absorption).

To avoid failures such as wear of a pump body of the compressor and demagnetization of a motor due to an overrun of operating temperature of the compressor, an electronic control system of the air conditioner usually controls the compressor based on temperature data. The temperature data comes from a temperature sensor disposed on an outer wall of the compressor. However, due to a weak mounting structure of the temperature sensor, the temperature sensor comes loose easily, which leads to distorted data of a temperature measurement, and is not conducive to protecting the compressor.

As illustrated in <FIG>, according to one embodiment of the present disclosure, a housing assembly applied in a compressor is provided. The compressor usually has a closed housing <NUM>. A motor and a compressor mechanism are both disposed in the housing <NUM>. An exhaust pipe <NUM> of the compressor is disposed on the housing <NUM>. A compressed high-temperature and high-pressure refrigerant gas is discharged from the exhaust pipe <NUM>.

It should be understood that, a temperature sensor <NUM> is disposed on an outer wall of the housing <NUM> to accurately detect a temperature of the housing <NUM>, thereby monitoring an operation state of the compressor. As illustrated in <FIG>, the temperature sensor <NUM> has a columnar shape. The temperature sensor <NUM> needs to be tightly attached to the outer wall of housing <NUM>, which can accurately measure the temperature of the housing <NUM>. Thus, a fixing bracket <NUM> is connected to the housing <NUM> to limit the temperature sensor <NUM>.

As illustrated in <FIG>, the fixing bracket <NUM> comprises a fixing portion <NUM> that covers the temperature sensor <NUM> and connection portions <NUM>. The connection portions <NUM> are configured to be fixedly connected to the housing <NUM>. Two connection portions <NUM> are provided and located on two sides of the fixing portion <NUM>, which realizes a fixed relative position between the fixing portion <NUM> and the housing <NUM>.

The fixing portion <NUM> comprises a top plate <NUM> and two side plates <NUM> arranged on two sides of the top plate <NUM>. That is, each side plate <NUM> is formed as a connection structure between the top plate <NUM> and the corresponding connection portion <NUM>. Each of the two side plates <NUM> is arranged in a tilted manner. An obtuse angle is formed between the side plate <NUM> and the top plate <NUM>. It should be understood that the top plate <NUM> and the two side plates <NUM> resemble three sides of a trapezoid. A mounting cavity <NUM> defined by the top plate <NUM>, the two side plates <NUM>, and the housing <NUM> has a substantially trapezoidal shape.

In addition, as illustrated in <FIG> and <FIG>, an opening slot <NUM> is formed on the top plate <NUM>. The opening slot <NUM> is located at an end of the top plate <NUM> facing away from the inlet end. Also, the opening slot <NUM> is slotted away from the inlet end and offset from a centerline of the top plate <NUM>. That is, the opening slot <NUM> is located at an edge position of the top plate <NUM>. With the opening slot <NUM>, elasticity of the top plate <NUM> is increased. Through a resetting force of an elastic deformation, the top plate <NUM> exerts pressure on the temperature sensor <NUM>. Since the opening slot <NUM> is not on the centerline of the top plate <NUM>, a deformation of the top plate <NUM> is biased to an edge of the opening slot <NUM>, thus a small deformation occurs at a position where the top plate <NUM> is in contact with the temperature sensor <NUM>, which is conducive to applying more stable pressure on the temperature sensor <NUM>, and reduces a risk of looseness of the temperature sensor <NUM> during the operation of the compressor.

During assembly, the temperature sensor <NUM> is inserted in the mounting cavity <NUM>. The temperature sensor <NUM> is in contact with the top plate <NUM>, the two side plates <NUM>, and the housing <NUM> simultaneously. Each of the two side plates <NUM> is in contact with the temperature sensor <NUM> at a position higher than an axis of the temperature sensor <NUM>. As illustrated in <FIG>, all of the top plate <NUM> and the two side plates <NUM> of the fixing portion <NUM> exert pressure on the temperature sensor <NUM>. A force F1 exerted by the top plate <NUM> is directed towards the housing <NUM> to enable the temperature sensor <NUM> to be tightly attached to the outer wall of the housing <NUM>, while forces F2 exerted by the two side plates <NUM> are symmetrical. A resultant force of the two forces F2 is also directed towards the housing <NUM>, which similarly enables the temperature sensor <NUM> to be tightly attached to the outer wall of the housing <NUM>. The opening slot <NUM> provides an elastic deformation to the top plate <NUM>. The resetting force of the elastic deformation is acted on the temperature sensor <NUM>. The temperature sensor <NUM> is kept in close contact with the housing <NUM> through limitations imposed by the top plate <NUM> and the two side plates <NUM> on the temperature sensor <NUM>, which allows the temperature sensor <NUM> to effectively and accurately detect the temperature of the housing <NUM>. Measurement data of the temperature sensor <NUM> is accurate and reliable. The fixing bracket <NUM> according to the embodiments of the present disclosure eliminates a defect of looseness of the temperature sensor <NUM>. The temperature sensor <NUM> can provide real-time feedback on the temperature of the housing <NUM>, which helps to accurately control an operation of the compressor, prevents the compressor from exceeding the operating temperature of the compressor, and avoids failures such as the wear of the pump body and the demagnetization of the motor.

It should be understood that, as illustrated in <FIG>, since the exhaust pipe <NUM> is configured to discharge the high-temperature and high-pressure refrigerant gas, a position where the exhaust pipe <NUM> is located is at a high temperature. Disposing a connection between the temperature sensor <NUM> and the housing <NUM> at a position adjacent to the exhaust pipe <NUM> can detect data more accurately, which helps to protect the compressor.

It should be understood that the fixing portion <NUM> is elastic and can be configured to position the temperature sensor <NUM>. The fixing portion <NUM> may be made of an elastic material, such as a copper alloy, or may have an elastically deformable structure, as long as the fixing portion <NUM> can limit the temperature sensor <NUM>.

As illustrated in <FIG>, it should be understood that, if the axial direction of the temperature sensor <NUM> is construed as a length direction of the top plate <NUM>, a direction perpendicular to the length direction is a width direction. To deviate the opening slot <NUM> from the temperature sensor <NUM>, a width of the opening slot <NUM> is set to be smaller than half of a width of the top plate <NUM>. In some embodiments, the width of the opening slot <NUM> is one-fifth of the width of the top plate <NUM>. Retaining a large area of the top plate <NUM> is favorable for applying pressure to the temperature sensor <NUM>.

As illustrated in <FIG>, it should be understood that, a spacing is reserved between the opening slot <NUM> and the flared opening <NUM>, in such a manner that the fixing portion <NUM> is at least partially intact. The partially-intact top plate <NUM> and the two side plates <NUM> exert pressure on the temperature sensor <NUM>, which facilitates fixation of the temperature sensor <NUM>.

It should be understood that an end of the fixing bracket <NUM> into which the temperature sensor <NUM> is mounted is defined as an inlet end. The temperature sensor <NUM> is inserted in the mounting cavity <NUM> from the inlet end. Usually, the inlet end has a large cross-sectional area to facilitate mounting of the temperature sensor <NUM>. As illustrated in <FIG> and <FIG>, to provide a sufficient limitation, an arc-shaped protrusion <NUM> may be formed on the top plate <NUM> at the inlet end. As illustrated in <FIG>, the arc-shaped protrusion <NUM> is an arc-shaped raised structure and faces towards the mounting cavity <NUM>. When the temperature sensor <NUM> is mounted in the mounting cavity <NUM>, the arc-shaped protrusion <NUM> abuts on the temperature sensor <NUM>. It should be understood that the arc-shaped protrusion <NUM> has an elastic structure and produces a small elastic deformation when in contact with the temperature sensor <NUM>. According to the principle of reaction force, the arc-shaped protrusion <NUM> exerts a force facing towards the housing <NUM> on the temperature sensor <NUM>, which prompts the temperature sensor <NUM> to be tightly attached to the outer wall of the housing <NUM>.

It should be understood that, the arc-shaped protrusion <NUM> may be disposed at the inlet end only, or the arc-shaped protrusion <NUM> may extend in an axial direction of the temperature sensor <NUM>, or a plurality of arc-shaped protrusions <NUM> may be disposed on the top plate <NUM> in the axial direction of the temperature sensor <NUM>. All of these examples can meet a requirement of limiting the temperature sensor <NUM>.

It should be understood that the mounting cavity <NUM> may be formed in a gradually-tapered cone shape. That is, in the axial direction of the temperature sensor <NUM>, the mounting cavity <NUM> is gradually tapered. The inlet end is located at a large size end to facilitate mounting of the temperature sensor <NUM>. A size of the large size end of the mounting cavity <NUM> may be set to be greater than a size of the temperature sensor <NUM>, while a size of a small size end of the mounting cavity <NUM> may be set to be smaller than that of the temperature sensor <NUM>. Considering that the top plate <NUM> and the two side plates <NUM> resemble three sides of a trapezoid, a cross section of the mounting cavity <NUM> is similar to a trapezoid. Thus, a width of the small size end of the mounting cavity <NUM> may be smaller than a diameter of the temperature sensor <NUM>, or a height of the small size end of the mounting cavity <NUM> may be smaller than the diameter of the temperature sensor <NUM>, or both the width and the height of the small size end of the mounting cavity <NUM> may be smaller than the diameter of the temperature sensor <NUM>. The opening slot <NUM> provides the elastic deformation to the fixing portion <NUM>, which can limit the temperature sensor <NUM>. When the temperature sensor <NUM> is mounted in the mounting cavity <NUM>, the temperature sensor <NUM> is limited by the gradually-tapered mounting cavity <NUM>, and the fixing portion <NUM> exerts pressure on the temperature sensor <NUM> to enable the temperature sensor <NUM> to be tightly attached to the outer wall of the housing <NUM>, in such a manner that the temperature sensor <NUM> is tightly attached to the housing <NUM>, allowing the temperature of the housing <NUM> to be accurately measured in real time. In addition, the small size end of the mounting cavity <NUM> can prevent the temperature sensor <NUM> from passing through the mounting cavity <NUM>, which facilitates accurate positioning.

It should be understood that the small size end of the mounting cavity <NUM> may also be set to match a cross-sectional area of the temperature sensor <NUM>. The temperature sensor <NUM> may be completely placed in the mounting cavity <NUM>, or the temperature sensor <NUM> may partially extend out of the mounting cavity <NUM>. The temperature sensor <NUM> is limited by the fixing portion <NUM> to keep abutting on the housing <NUM>, thus the temperature of the housing <NUM> can be detected accurately in real time.

It should be understood that the small size end of the mounting cavity <NUM> may also be set to be slightly greater than the temperature sensor <NUM> to allow the temperature sensor <NUM> to partially extend out of the mounting cavity <NUM>.

It should be understood that a structure of the top plate <NUM> arranged in a tilted manner is used to achieve gradual tapering of the mounting cavity <NUM> is that the top plate <NUM>. In the axial direction of the temperature sensor <NUM>, the top plate <NUM> is tilted towards the housing <NUM> in a direction facing away from the inlet end. That is, a distance between the top plate <NUM> and the housing <NUM> gradually decreases, making the mounting cavity <NUM> present a gradually-tapered structure. In addition, the tilted top plate <NUM> exerts, on the temperature sensor <NUM>, a force facing towards the housing <NUM>, prompting the temperature sensor <NUM> to be tightly attached to the outer wall of the housing <NUM>.

It should be understood that a structure used to achieve gradual tapering of the mounting cavity <NUM> is that the two side plates <NUM> gradually approach each other. In the axial direction of the temperature sensor <NUM>, a distance between the two side plates <NUM> gradually decreases in the direction facing away from the inlet end, making the mounting cavity <NUM> present a gradually-tapered structure. In addition, with the above structure, the two side plates <NUM> exert a greater force on the temperature sensor <NUM>, which helps to induce the temperature sensor <NUM> to be tightly attached to the outer wall of the housing <NUM>. In addition, the two side plates <NUM> further cooperate to clamp the temperature sensor <NUM>, which prevents the temperature sensor <NUM> from escaping from the mounting cavity <NUM>.

The top plate <NUM> arranged in the tilted manner and the two side plates <NUM> gradually approaching each other may be adopted simultaneously, to achieve the gradual tapering of the mounting cavity <NUM>. When the temperature sensor <NUM> is mounted in the mounting cavity <NUM>, all of the top plate <NUM> and the two side plates <NUM> apply pressure to the temperature sensor <NUM> to enable the temperature sensor <NUM> to be tightly attached to the outer wall of the housing <NUM>. In addition, the two side plates <NUM> further cooperate to clamp the temperature sensor <NUM>, which prevents the temperature sensor <NUM> from escaping from the mounting cavity <NUM>.

As illustrated in <FIG>, it should be understood that a flared opening <NUM> is formed on the fixing bracket <NUM>. A cross section of the flared opening <NUM> is greater than a cross section of the temperature sensor <NUM>. The flared opening <NUM> is the inlet end and formed as an inlet of the mounting cavity <NUM>. That is, the temperature sensor <NUM> is mounted in the mounting cavity <NUM> from the flared opening <NUM>. The flared opening <NUM> is configured to enlarge a space for entry to facilitate mounting of the temperature sensor <NUM>. In addition, an inner wall surface of the flared opening <NUM> has a horn shape, which can facilitate centering of the temperature sensor <NUM> to enable the temperature sensor <NUM> to enter the mounting cavity <NUM> accurately, improving a mounting efficiency.

It should be understood that, considering that the fixing bracket <NUM> is configured to fix the temperature sensor <NUM>, and the fixing portion <NUM> needs to apply pressure to the temperature sensor <NUM> to prompt the temperature sensor <NUM> to be in contact with the outer wall of the housing <NUM>, a length occupied by the flared opening <NUM> in the axial direction of the temperature sensor <NUM> is set to be smaller than one-third of a length of the fixing bracket <NUM>. In some embodiments, the length of the flared opening <NUM> is one-tenth of the length of the fixing bracket <NUM>, which enables nine-tenths of a length of the fixing portion <NUM> to exert pressure on the temperature sensor <NUM>. Thus, the pressure is sufficient to limit the temperature sensor <NUM>.

It should be understood that a length of an effective temperature-sensing region of the temperature sensor <NUM> in an axial direction is an effective temperature-sensing length. The effective temperature-sensing length is fixed. Setting the length of the fixing portion <NUM> to be smaller than the effective temperature-sensing length is conducive to observing whether the temperature sensor <NUM> is in close contact with the housing <NUM> and reduces a resistance during the assembly.

As illustrated in <FIG>, it should be understood that a heat-sensitive sleeve <NUM> is usually sleeved on the temperature sensor <NUM>. Considering that a position where the temperature sensor <NUM> is mounted in the mounting cavity <NUM> needs to be accurately positioned, the cross section of the flared opening <NUM> is set to be smaller than a cross section of the heat-sensitive sleeve <NUM>. That is, the heat-sensitive sleeve <NUM> is kept out of the flared opening <NUM> to provide a position limitation. During the assembly of the temperature sensor <NUM>, the heat-sensitive sleeve <NUM> abuts on the flared opening <NUM> to provide position positioning of the heat-sensitive sleeve <NUM>, accurately defining a mounting depth of the temperature sensor <NUM>.

It should be understood that, to define the length of the temperature sensor <NUM> mounted in the mounting cavity <NUM>, other structural forms may be used. For example, an end of the fixing bracket <NUM> opposite to the flared opening <NUM> may be formed as a closed structure. When the temperature sensor <NUM> is mounted in the mounting cavity <NUM>, the temperature sensor <NUM> may be directly inserted at a bottom of the mounting cavity <NUM>, which is simple and convenient.

Alternatively, a position limiting structure such as a position limiting ring may be disposed on an inner wall of the fixing portion <NUM>. The temperature sensor <NUM> is mounted in the mounting cavity <NUM>, until the temperature sensor <NUM> abuts on the position limiting ring.

Alternatively, a pressing sheet <NUM> is disposed at an end of the side plate <NUM> facing away from the flared opening <NUM>. The pressing sheet <NUM> extends in the axial direction of the temperature sensor <NUM>. When the temperature sensor <NUM> is mounted in the mounting cavity <NUM>, whether the temperature sensor <NUM> is mounted in place may be determined through observing relative positions of the temperature sensor <NUM> and the pressing sheet <NUM>. Two pressing sheets <NUM> may also apply clamping forces to the temperature sensor <NUM> to fix the temperature sensor <NUM>, preventing the temperature sensor <NUM> from escaping from the mounting cavity <NUM>.

As illustrated in <FIG>, it should be understood that, two welds <NUM> are arranged on each connection portion <NUM>, and a total of four welds <NUM> are on the fixing bracket <NUM>. The welds are configured to cooperate with the housing <NUM> to realize welding. The welding is realized in a method of resistance welding to fix the connection portions <NUM> on the outer wall of the housing <NUM>. The resistance welding is a method of welding by using resistance heat, which is generated when a current passes through a weldment and a contact position, as a heat source to heat the weldment locally, and heating a workpiece to a molten or plastic state at a contact surface of the workpiece and an adjacent region while applying pressure. During welding, no filler metal is required, leading to high productivity, small deformation of the weldment, and easy automation. To accurately define a region to be welded, two welds <NUM> are arranged on each connection portion <NUM>. As illustrated in <FIG>, the weld <NUM> is a protrusion facing towards the housing <NUM>. The weld used in conjunction with the resistance welding process can improve a welding efficiency.

It should be understood that the connection portions <NUM> may also be mounted on the housing <NUM> through fixtures. For example, the connection portions <NUM> are fixedly connected to the housing <NUM> through screws. The connection portions <NUM> may also be adhered to the housing <NUM> through glue to achieve fixation.

According to one embodiment of the present disclosure, a compressor is provided. The compressor comprises the housing assembly according to the above-mentioned embodiments. The fixing bracket <NUM> is connected to the housing <NUM> of the compressor. The fixing portion <NUM> of the fixing bracket <NUM> comprises the top plate <NUM> and the two side plates <NUM>. The two side plates <NUM> are arranged on two sides of the top plate <NUM>. Each of the two side plates <NUM> is arranged in a tilted manner. An obtuse angle is formed between the side plate <NUM> and the top plate <NUM>. It should be understood that the top plate <NUM> and the two side plates <NUM> resemble three sides of a trapezoid, enabling the mounting cavity <NUM> defined by the top plate <NUM>, the two side plates <NUM>, and the housing <NUM> to have a trapezoidal cross section.

During assembly, the temperature sensor <NUM> is inserted in the mounting cavity <NUM>. The temperature sensor <NUM> is in contact with the top plate <NUM>, the two side plates <NUM>, and the housing <NUM> simultaneously. Each of the two side plates <NUM> is in contact with the temperature sensor <NUM> at the position higher than the axis of the temperature sensor <NUM>. As illustrated in <FIG>, all of the top plate <NUM> and the two side plates <NUM> of the fixing portion <NUM> exert pressure on the temperature sensor <NUM>. The force F1 exerted by the top plate <NUM> is directed towards the housing <NUM> to enable the temperature sensor <NUM> to be tightly attached to the outer wall of the housing <NUM>, while the forces F2 exerted by the two side plates <NUM> are symmetrical. The resultant force of the two forces F2 is also directed towards the housing <NUM>, which similarly enables the temperature sensor <NUM> to be tightly attached to the outer wall of the housing <NUM>. The opening slot <NUM> provides the elastic deformation to the top plate <NUM>. The resetting force of the elastic deformation is acted on the temperature sensor <NUM>. The temperature sensor <NUM> is kept in close contact with the housing <NUM> through limitations imposed by the top plate <NUM> and the two side plates <NUM> on the temperature sensor <NUM>, which allows the temperature sensor <NUM> to effectively measure the temperature of the housing <NUM>. The measurement data of the temperature sensor <NUM> is accurate and reliable. The fixing bracket <NUM> according to the embodiments of the present disclosure eliminates the defect of looseness of the temperature sensor <NUM> and ensures that the temperature sensor <NUM> accurately detects the temperature of the housing <NUM>. The temperature sensor <NUM> can provide real-time feedback on the temperature of the housing <NUM>, which helps to accurately control the operation of the compressor, prevents the compressor from exceeding the operating temperature of the compressor, and avoids failures such as the wear of the pump body and the demagnetization of the motor.
