Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a caravan air conditioner according to an embodiment of the present invention.

The embodiment of the utility model provides a car as a house air conditioner, including the casing, still include: a four-way valve 4; a support plate 1 fixedly arranged in the casing; an elastic pad 5 wrapped outside the four-way valve 4; the elastic pad 5 is fixedly provided on the pressing plate 6 of the supporting plate 1.

The embodiment of the utility model provides a car as a house air conditioner, through increasing cross valve 4, develop the heat pump system of car as a house air conditioner, compare with adopting electric heating device among the prior art, when reducing the potential safety hazard, effectively improved the heating capacity to satisfy the heat supply demand and the energy-conserving demand of car as a house; and, through being fixed in the backup pad 1 with cross valve 4 with cushion 5 on, backup pad 1 and casing fixed connection, with the reliable fixed of cross valve 4, effectively avoided the condition that produces the pipeline spare fatigue because of cross valve 4 rocks in the driving process, further reduced the potential safety hazard.

As shown in fig. 2, the four-way valve 4 is connected in the same manner as in the air conditioning system, and includes a D-pipe connected to the outlet of the compressor of the motor home air conditioner, an S-pipe connected to the inlet of the compressor, an E-pipe connected to the evaporator (in a cooling state), and a C-pipe connected to the condenser (in a cooling state).

In order to facilitate the installation of backup pad 1, ensure its fixed stability, the embodiment of the utility model provides an among the car as a house air conditioner, 3 fixed connection of one end of backup pad 1 and the face lid of casing, the other end of backup pad 1 and the condenser top cap 2 fixed connection of casing. The supporting plate 1 can also be fixed with a side plate or a top plate of a motor home air conditioner, and the specific fixing mode is not limited.

The four-way valve 4 is arranged on one surface of the supporting plate 1 far away from the condenser top cover 2. In the installation, set up backup pad 1 fixed earlier on condenser top cap 2, place cross valve 4 again and accomplish fixedly on backup pad 1, effectively made things convenient for the installation of cross valve 4.

In the present embodiment, the pressure plate 6 is connected to the support plate 1 by screws 7. An accommodating groove for accommodating the elastic pad 5 is formed in the middle of the pressing plate 6, and in the installation process, the elastic pad 5 is wrapped outside the four-way valve 4 and then is arranged in the accommodating groove of the pressing plate 6; screw mounting holes at two ends of the pressure plate 6 are aligned with mounting holes on the support plate 1, and connection is completed through screws 7.

As shown in fig. 3, in the air conditioner for a motor home provided by the embodiment of the present invention, the elastic pad 5 includes an upper rubber pad 51 and a lower rubber pad 52, and the four-way valve 4 is disposed between the upper rubber pad 51 and the lower rubber pad 52. By arranging the elastic cushion 5 as a split structure, the relative installation of the elastic cushion 5 and the four-way valve 4 is effectively facilitated.

Further, the elastic pad 5 provided in this embodiment is a rubber pad, and may also be a resin pad or a cushion block made of other material with strong elasticity.

The elastic pad 5 may be provided in an integrated structure, and the elastic pad 5 is wrapped around the four-way valve 4 through elastic deformation thereof.

Wherein, in order to improve the matching stability of the elastic pad 5 and the four-way valve 4, a lower pipe groove for accommodating an E pipe, an S pipe and a C pipe of the four-way valve is arranged on the lower rubber pad 52; the number of the lower pipe grooves is 3, and the lower pipe grooves correspond to the E pipes, the S pipes and the C pipes of the four-way valve 4 one by one. Preferably, 3 lower flutes are arranged parallel to each other.

In the process of installing the elastic cushion 5 and the four-way valve 4 on the supporting plate 1, the lower rubber cushion 52 is placed on the supporting plate 1, then the four-way valve is placed on the lower rubber cushion 52, so that the E pipe, the S pipe and the C pipe of the four-way valve are respectively in one-to-one correspondence with 3 lower pipe grooves on the lower rubber cushion 52, the upper rubber cushion 51 covers the four-way valve 4, the elastic cushion 5 is ensured to wrap the four-way valve, and the installation of the pressure plate 6 is completed and the four-way valve is fixed.

Further, the embodiment of the present invention provides an upper rubber pad 51 on which an upper pipe groove is provided corresponding to the lower pipe groove of the lower rubber pad 52. That is, the number of the upper pipe grooves is 3 and corresponds to 3 lower pipe grooves arranged on the lower rubber mat 52 one by one, so that after the elastic mat 5 and the four-way valve 4 are installed relatively, the 3 upper pipe grooves correspond to the E pipe, the S pipe and the C pipe of the four-way valve 4 one by one.

Since the tubes E, S and C of the four-way valve 4 are generally circular tubes, in this embodiment, the upper tube slot of the upper rubber pad 51 and the lower tube slot of the lower rubber pad 52 are both semicircular tube slots. The diameter of the semicircular pipe groove is the same as the diameter of the pipe of the four-way valve 4 corresponding thereto.

As shown in fig. 3, the upper rubber pad 51 has a trapezoidal cross section, which is preferably an isosceles trapezoid. The plane of the upper bottom of the cross section of the upper rubber pad 51 is the contact surface of the upper rubber pad 51 and the pressing plate 6. That is, the lower bottom of the cross section of the upper gasket 51 is a surface provided with an upper duct groove, which forms a space for accommodating the duct of the four-way valve 4 in cooperation with the lower gasket 52. Because the cross section of the upper rubber cushion 51 is trapezoidal, the pressing plate 6 is contacted with the top surface of the upper rubber cushion 51 and extrudes the upper rubber cushion 51 towards the lower rubber cushion 52 in the mounting process, and because the cross section of the upper rubber cushion 51 is trapezoidal, the relative stability of the upper rubber cushion 51 and the lower rubber cushion 52 in the extrusion process is ensured, the upper rubber cushion 51 and the lower rubber cushion 52 are prevented from being staggered with each other, and the mounting stability is effectively improved.

In order to facilitate the valve body of cross valve 4 to be fixed, the embodiment of the utility model provides an in the car as a house air conditioner, the length of going up cushion 51 is less than the length of cushion 52 down, and the one end of going up cushion 51 aligns with the one end of cushion 52 down. Wherein, the other end of the upper rubber pad 51 is shorter than the other end of the lower rubber pad 52, so that a part of the lower rubber pad 52 close to the other end is exposed to the outside, so as to place the valve body of the four-way valve 4 at the position, and further ensure the fixing stability of the four-way valve 4.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The previous description of the disclosed embodiments is provided to enable any person 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 generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
