Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, and in particular to a circulating heating type air source heat pump water heater. Background Technology

[0002] Air source heat pump water heaters, also known as "air-source heat pump water heaters," operate on a principle very similar to air conditioners. They use a small amount of electricity to drive a compressor. High-pressure liquid refrigerant evaporates into a gaseous state in the evaporator after passing through an expansion valve, absorbing a large amount of heat energy from the air. The gaseous refrigerant is then compressed by the compressor into a high-temperature, high-pressure liquid state, which then enters the condenser to release heat and heat the water. This cycle continues, heating the water to 50°C~65°C. In this process, one unit of electricity is consumed to drive the compressor, while approximately four units of heat are absorbed and transferred from the ambient air to the water. Therefore, compared to electric water heaters, air source heat pump water heaters can save nearly three-quarters of the electricity.

[0003] Most air source heat pump water heaters on the market cannot quickly cool down the high-temperature liquid refrigerant when heating the water to allow it to enter the next cycle. At the same time, when absorbing low-temperature heat energy from the air, they cannot filter out dust and impurities from the air, thus affecting the working efficiency of the compressor. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the fact that most air source heat pump water heaters on the market, as described above or in the prior art, cannot quickly cool down the high-temperature liquid refrigerant when heating the water so that it can enter the next cycle, and cannot filter dust and impurities in the air when absorbing low-temperature heat energy, thus affecting the working efficiency of the compressor, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a circulating heating air source heat pump water heater.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a circulating heating air source heat pump water heater, including a heat pump housing, an installation chamber installed at the top of the heat pump housing, an air inlet pipe installed on the outer wall of the installation chamber, an air outlet pipe installed at the end of the installation chamber away from the air inlet pipe, and a filter sleeve fitted on the outer wall of the air inlet pipe; an installation and disassembly assembly installed on the outer wall of the installation chamber, a bracket installed at the bottom of the heat pump housing, a water tank assembly installed inside the heat pump housing, and a first groove formed on the outer wall of the air inlet pipe.

A vertical rod is fixedly installed at the top and bottom of the second groove, and a sliding sleeve is sleeved on the outer wall of the vertical rod. An L-shaped limiting rod penetrating a first through hole is installed on the outer wall of the sliding sleeve, and the L-shaped limiting rod is engaged with the first groove. A U-shaped handle is installed at the top of the L-shaped limiting rod.

[0015] By adopting the above technical solution, the L-shaped limiting rod is prevented from engaging with the first through hole through the cooperation of the first through hole and the L-shaped limiting rod, thus facilitating the installation and removal of the filter sleeve and the air inlet pipe by the operator.

[0016] As a preferred embodiment of the circulating heating air source heat pump water heater of this utility model, the outer wall of the vertical rod is fitted with a high-pressure spring body, and the top and bottom ends of the high-pressure spring body are respectively fixedly connected to the side wall of the second groove and the sliding sleeve.

[0017] By adopting the above technical solution and through the design of the high-pressure spring body, the elastic recovery of the high-pressure spring body drives the sliding sleeve to reciprocate up and down.

[0018] In a preferred embodiment of the circulating heating air source heat pump water heater of this utility model, the water tank assembly includes a water tank body, which is disposed inside the heat pump housing.

[0023] By adopting the above technical solution, the first connecting pipe passes through the second through hole in a meandering shape, thereby improving the heat absorption effect of the copper plate on the first connecting pipe.

[0024] The circulating heating air source heat pump water heater of this utility model has the following beneficial effects:

[0025] This invention firstly designs the compressor body to compress low-temperature heat in the air, causing the high-temperature liquid refrigerant generated by compression to enter the interior of the heating sleeve through the second connecting pipe. The heating sleeve, in a meandering shape, is fitted onto the outer wall of the water tank body to heat the water inside. Simultaneously, the heated high-temperature liquid refrigerant circulates through the first connecting pipe, passes through the second through hole, and enters the interior of the compressor body. The design of the copper plate and the second through hole allows for rapid heat absorption of the first connecting pipe, and the exhaust fan body is activated to quickly dissipate heat from the first connecting pipe and the copper plate, resulting in better rapid heat dissipation of the high-temperature liquid refrigerant.

[0026] This invention firstly utilizes the design of the second filter body to filter dust and lint, preventing air from entering the installation chamber and the compressor body, thus avoiding damage to the compressor body caused by dust and lint. Simultaneously, an L-shaped limiting rod engages with the first groove, and the filter sleeve cooperates with the air inlet pipe. This causes the L-shaped limiting rod to move the sliding sleeve up and down on the outer wall of the vertical rod, compressing the high-pressure spring body and causing deformation. The elastic recovery of the high-pressure spring body then drives the L-shaped limiting rod to reciprocate up and down, facilitating the removal of the L-shaped limiting rod from engaging with the first groove, thus making it easier for operators to disassemble and replace the filter sleeve.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0038] Example 1: Refer to Figures 1-5This is the first embodiment of the present invention. This embodiment provides a circulating heating air source heat pump water heater, which can solve the problems of most air source heat pump water heaters on the market, such as the inability to quickly cool down the high-temperature liquid refrigerant when heating the water temperature so that it can enter the next cycle, and the inability to filter dust and impurities in the air when absorbing low-temperature heat energy, thus affecting the working efficiency of the compressor. It includes a heat pump housing 1, an installation chamber 2 installed at the top of the heat pump housing 1, an air inlet pipe 3 installed on the outer wall of the installation chamber 2, an air outlet pipe 4 installed at the end of the installation chamber 2 away from the air inlet pipe 3, a filter sleeve 5 sleeved on the outer wall of the air inlet pipe 3; an installation and disassembly assembly 6 installed on the outer wall of the installation chamber 2; a bracket 7 installed at the bottom of the heat pump housing 1; a water tank assembly 8 installed inside the heat pump housing 1; and a first groove 301 opened on the outer wall of the air inlet pipe 3.

[0039] The compressor body 201 is installed at the bottom of the installation compartment 2, and the output end of the compressor body 201 is connected to a first connecting pipe 202 that penetrates the interior of the heat pump housing 1. The input end of the compressor body 201 is connected to a second connecting pipe 203 that penetrates the interior of the heat pump housing 1. By starting the compressor body 201, compressed hot air is driven into the second connecting pipe 203 and circulated through the first connecting pipe 202.

[0040] An exhaust fan body 401 is installed inside the exhaust pipe 4, and a first filter body 402 is installed inside the exhaust pipe 4. The design of the first filter body 402 is used to filter dust and lint in the air.

[0041] The water tank assembly 8 includes a water tank body 801, which is disposed inside the heat pump housing 1. A fixing seat 802 is installed at the bottom of the water tank body 801, and the bottom of the fixing seat 802 is fixedly connected to the bottom of the interior of the heat pump housing 1. Heating sleeves 803 are installed on the outer wall of the water tank body 801. The heating sleeves 803 are connected to the first connecting pipe 202 and the second connecting pipe 203 respectively. A heating pipe 804 is installed at the top of the water tank body 801. A hot water outlet 805 penetrating the heat pump housing 1 is installed on the outer wall of the water tank body 801. A cold water outlet 806 penetrating the heat pump housing 1 is installed on the outer wall of the water tank body 801. Through the design of the heating sleeves 803, the water inside the water tank body 801 is heated through the first connecting pipe 202 and the second connecting pipe 203 and through the heating sleeves 803.

[0042] The heat dissipation assembly 9 includes a mounting bracket 901, which is fixedly installed at the top of the mounting chamber 2. A copper plate 902 is installed at the bottom of the mounting bracket 901, and a second through hole 903 is opened inside the copper plate 902. The first connecting pipe 202 passes through the second through hole 903 in a meandering shape. By the first connecting pipe 202 passing through the second through hole 903 in a meandering shape, the heat absorption effect of the first connecting pipe 202 through the copper plate 902 is better.

[0043] The specific working principle is as follows: First, the compressor body 201 is designed to compress low-temperature heat in the air. The high-temperature liquid refrigerant generated by the compression enters the interior of the heating sleeve 803 through the second connecting pipe 203. The heating sleeve 803 is arranged in a meandering shape on the outer wall of the water tank body 801 to heat the water inside the water tank body 801. At the same time, the heated high-temperature liquid refrigerant circulates through the first connecting pipe 202, through the second through hole 903, and into the interior of the compressor body 201. The copper plate 902 and the second through hole 903 are designed to quickly absorb heat from the first connecting pipe 202. The exhaust fan body 401 is activated to quickly dissipate heat from the first connecting pipe 202 and the copper plate 902, thus improving the rapid heat dissipation effect of the high-temperature liquid refrigerant.

[0044] Example 2: Refer to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a circulating heating air source heat pump water heater, which solves the problems of most air source heat pump water heaters on the market, such as the inability to quickly cool down the high-temperature liquid refrigerant when heating the water so that it can enter the next cycle, and the inability to filter dust and impurities in the air when absorbing low-temperature heat energy, thus affecting the working efficiency of the compressor. The filter sleeve 5 is sleeved on the outer wall of the air inlet pipe 3. The filter sleeve 5 has a second filter screen body 501 inside. The top and bottom of the filter sleeve 5 are provided with first through holes 502. Through the cooperation of the first through holes 502 and the L-shaped limiting rod 605, the L-shaped limiting rod 605 is not locked with the first through holes 502, so as to facilitate the operator to install and disassemble the filter sleeve 5 and the air inlet pipe 3.

[0045] The installation and disassembly assembly 6 includes a second groove 601, which is formed on the outer wall of the installation chamber 2. A vertical rod 602 is fixedly installed at the top and bottom of the second groove 601, and a sliding sleeve 603 is sleeved on the outer wall of the vertical rod 602. An L-shaped limiting rod 605 that penetrates the first through hole 502 is installed on the outer wall of the sliding sleeve 603, and the L-shaped limiting rod 605 is engaged with the first groove 301. A U-shaped handle 606 is installed at the top of the L-shaped limiting rod 605. A high-pressure spring body 604 is sleeved on the outer wall of the vertical rod 602, and the top and bottom of the high-pressure spring body 604 are fixedly connected to the side walls of the second groove 601 and the sliding sleeve 603, respectively. Through the design of the high-pressure spring body 604, the sliding sleeve 603 is reciprocated and raised and lowered by the elastic recovery of the high-pressure spring body 604.

[0046] The specific working principle is as follows: First, the design of the second filter body 501 filters dust and lint, preventing air from entering the installation chamber 2 and the compressor body 201, thus preventing damage to the compressor body 201 caused by dust and lint. At the same time, the L-shaped limiting rod 605 engages with the first groove 301, and the filter sleeve 5 cooperates with the air inlet pipe 3, causing the L-shaped limiting rod 605 to drive the sliding sleeve 603 to rise and fall on the outer wall of the vertical rod 602, compressing the high-pressure spring body 604 to deform. The elastic recovery of the high-pressure spring body 604 then drives the L-shaped limiting rod 605 to reciprocate, making it easier for the L-shaped limiting rod 605 to no longer engage with the first groove 301, thus facilitating the operator to disassemble and replace the filter sleeve 5.

[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
